Various changes can be made according to the design, etc., as long as they do not deviate from the concept.

(Embodiment 1)
1. Configuration 1-1. Overview FIG. 1 is a block diagram showing a configuration example of an elevator system 100 including an elevator group management system 1 according to an embodiment of the present invention. The elevator system 100 integrally controls the running and operation of a plurality of elevators 40A to 40F using an elevator group management system 1. In the present embodiment, as an example, six elevators 40A to 40F (hereinafter referred to as "cars" as appropriate) are provided, A to F. Note that in the following, each of the elevators 40A to 40F may be referred to as "elevator 40" without distinction.

The elevator system 100 includes an elevator group management system 1 and a plurality of elevators 40A to 40F. The elevator group management system 1 includes a group management control device 10, a plurality of destination floor registration devices 20, and a plurality of elevator control devices 30A to 30F. Note that hereinafter, each of the elevator control devices 30A to 30F may be referred to as "elevator control device 30" without distinction.

The elevator group management system 1 employs a destination floor registration method. In this embodiment, the destination floor registration device 20 is installed at or near the landing of each floor. The user performs a predetermined registration operation on the destination floor registration device 20 in order to specify a desired destination floor. This system 1 allocates the registered destination floor to any one of elevators 40A to 40F of elevators A to F, and sends an assignment indicating the allocated elevator 40 (assigned car) to the destination floor registration device 20. Display machine number information. By viewing the display on the destination floor registration device 20 during the registration operation, the user can recognize the assigned aircraft number he/she should board.

Each elevator 40 has a car, a hoist (motor), a counterweight, a weight sensor, and the like. The weight sensor is provided under the floor of the car of the elevator 40, for example, and can measure the weight inside the car. The weight sensor may be a sensor that measures the weight by measuring the tension of the rope suspending the elevator 40.

The elevator control device 30 of each elevator 40 controls the operation of the hoisting machine, etc. based on the control signal (assigned call signal) from the group management control device 10, thereby controlling the raising, lowering, stopping, and running speed of the car. control etc. In this embodiment, each elevator 40 is a variable speed elevator.

A variable speed elevator is an elevator that can run at a faster speed than the rated speed if the weight difference between the car (including users (passengers)) and the counterweight is small and the distance traveled is at least a predetermined distance. be. Rated speed is the maximum speed when going up and down. When the weight difference between the car and the counterweight is small, for example, when the load is about 40% to 60% of the rated load capacity, in this case, the hoisting machine required to raise and lower the car at the rated speed is The output may be smaller than when the weight difference is large. In other words, when the weight difference is small, the hoist has surplus output power even when the car runs at the rated speed. Therefore, the elevator control device 30 is able to increase the traveling speed of the elevator 40 beyond the rated speed. For example, if the rated speed is 45 m/min, the running speed can be increased to 60 m/min.

The elevator control device 30 of the elevator 40 causes the car (elevator 40) to run at a running speed faster than the rated speed by controlling the rotational speed of the hoist and the like when speed-up operation conditions are satisfied. Hereinafter, operating each elevator 40 at a traveling speed faster than the rated speed will be referred to as "speed-up operation" as appropriate.

Speed-up operation can be performed by satisfying speed-up operation conditions. In this embodiment, the speed-up driving conditions are such that (1) the distance traveled in the traveling section is greater than or equal to a predetermined threshold distance (hereinafter referred to as "traveling distance condition"), and (2) the occupancy rate in the car is within a predetermined range. (hereinafter referred to as the "occupancy rate condition"). The traveling section is a section between two floors in which the elevator 40 can travel. The occupancy rate may be defined by the load inside the car, or may be defined by the number of people riding in the car.

When the occupancy rate is determined by the live load, the above-mentioned predetermined range is the lower limit corresponding to the minimum live load in the car, where there is margin in the output of the hoist, and the lower limit, which corresponds to the minimum load in the car, where there is margin in the output of the hoist. and the upper limit corresponding to the maximum carrying load within. When the occupancy rate is defined by the number of people, the above-mentioned predetermined range includes a lower limit corresponding to the minimum number of passengers in the car, which provides a margin for the output of the hoisting machine, and an upper limit corresponding to the maximum number of passengers in the car, Set by. Further, the lower limit and upper limit of the predetermined range can be set based on the capacity of the car.

1-2. Configuration of Group Management Control Device The group management control device 10 includes a control section 11 , a storage section 12 , and an input/output interface 13 .

The control unit 11 controls the operation of the group management control device 10 as a whole. The control unit 11 may be composed of, for example, an arithmetic circuit. The control unit 11 includes a general-purpose processor such as a CPU or MPU that implements predetermined processing or functions by executing a program. The control unit 11 is configured to be able to communicate with the storage unit 12, and realizes various functions in the control unit 11 by reading and executing arithmetic programs stored in the storage unit 12.

For example, the control unit 11 realizes a function of allocating the destination floor registered in the destination floor registration device 20 to any one of the elevators 40 among the plurality of elevators 40A to 40F. Specifically, upon receiving the allocation request signal from the destination floor registration device 20 via the input/output interface 13, the control unit 11 starts the process of allocating the elevator 40. The assignment request signal is a signal requesting that the destination floor registered in the destination floor registration device 20 be assigned to one of the plurality of elevators 40A to 40F. The allocation request signal includes destination floor information, departure floor information, and identification information, which will be described later. The control unit 11 allocates the destination floor indicated by the received allocation request signal to one of the plurality of elevators 40A to 40F.

Based on the operation information of each elevator 40, the control unit 11 determines the elevator 40 (assigned car number) to which the destination floor is to be assigned by performing predetermined calculation processing. The operation information of each elevator 40 includes, for example, the destination floor and departure floor related to the destination floor call assigned to each elevator 40, the state of the car of each elevator 40, the expected waiting time (predicted waiting time), and the expected service. Contains information indicating completion time, number of scheduled car stops, etc. The state of the car of the elevator 40 includes the position of the car, the direction of travel, the open/closed state of the door, the load, and the like. The service completion time is the time until the assigned car arrives at the destination floor. The number of times the car is scheduled to stop is the number of times the elevator 40 is scheduled to stop until the service is completed.

For example, the control unit 11 calculates, for each elevator 40, an evaluation value for selecting the elevator 40 (assigned car) to which the destination floor should be assigned, based on the operation information of each elevator 40. After calculating the evaluation value, the control unit 11 selects the elevator 40 having the highest evaluation value from among the elevators 40A to 40F, and assigns the destination floor to the selected elevator 40. In this embodiment, the predicted waiting time is recorded in a predetermined predicted waiting time table stored in the storage unit 12, for example. Such arithmetic processing can be set as appropriate, for example, according to various allocation methods of destination floor calls.

In the present embodiment, in the above allocation process, the control unit 11 selects an elevator that is predicted to satisfy the speed-up operation condition by boarding the elevator 40 that is operating in the opposite direction to the direction that the user wants to go. 40, the elevator 40 is selected as a candidate for the assigned elevator. The operation of the group management control device 10 of this embodiment will be described later.

When the control unit 11 determines the allocated car number, it determines an allocated car signal indicating the determined allocated car number, and transmits the allocated car signal via the input/output interface 13 to the destination floor registration device 20 that transmitted the allocation request signal. The control unit 11 thereby notifies the destination floor registration device 20 of the allocated car number in response to receiving the allocation request signal. The assigned car signal may include reverse direction boarding information, which will be described later.

Further, when the assigned car is determined, the control unit 11 generates an assigned call signal regarding the departure floor and destination floor of the destination floor call, and sends the assigned call signal via the input/output interface 13 to the elevator control device 30 that controls the assigned car. Send. The control unit 11 thereby transmits information for operating the elevator 40 from the user's departure floor to the destination floor to the elevator control device 30 in response to receiving the allocation request signal. The assignment call signal may include a reverse direction stop command, which will be described later.

The control unit 11 is not limited to a mode in which hardware resources and software cooperate to realize a predetermined function, but may be configured with a hardware circuit specifically designed to realize a predetermined function. That is, the control unit 11 can be realized by various processors such as GPU, FPGA, DSP, ASIC, etc. in addition to CPU and MPU. Such a control unit 11 may be realized by, for example, a signal processing circuit that is a semiconductor integrated circuit.

The storage unit 12 is a storage medium that can store various information. The information includes programs and data. For example, as described above, the storage unit 12 stores calculation programs for realizing various functions according to the present embodiment. Furthermore, the storage unit 12 stores operation information of each elevator 40. The storage unit 12 is realized by, for example, a memory such as DRAM, SRAM, or flash memory, an HDD, an SSD, another storage device, or an appropriate combination thereof.

The input/output interface 13 is an interface for transmitting and receiving various signals between the group management control device 10, the destination floor registration device 20, and the elevator control devices 30A to 30F. The input/output interface 13 converts the signal output from the control unit 11 into a signal in a predetermined format and outputs the signal. In addition, the input/output interface 13 converts signals input from the destination floor registration device 20 and the elevator control devices 30A to 30F into signals in a predetermined format, and outputs the signals to the control unit 11.

1-3. Configuration of Destination Floor Registration Device FIG. 2 is a block diagram showing the configuration of the destination floor registration device 20 of the elevator group management system 1 according to the present embodiment.

The destination floor registration device 20 includes a control section 21, a storage section 22, an input/output interface 23, a notification section 24, and an operation section 25.

The control unit 21 controls the operation of the destination floor registration device 20. The control unit 21 is configured to be able to communicate with the storage unit 22, and realizes various functions in the control unit 21 by reading and executing arithmetic programs and the like stored in the storage unit 22. For example, the control unit 21 can output a display signal to the notification unit 24 to display the number of the elevator 40 and the running direction of the elevator 40 on the notification unit 24 to notify the user. The control unit 21 may be configured similarly to the control unit 11 described above.

The storage unit 22 is a storage medium that can store various information. The storage unit 22 may be configured similarly to the storage unit 12 described above.

The input/output interface 23 is an interface for transmitting and receiving signals between the destination floor registration device 20 and the group management control device 10. The input/output interface 23 converts the signal output from the control unit 21 into a signal in a predetermined format and outputs the signal. Further, the input/output interface 23 converts a signal input from the group management control device 10 into a signal in a predetermined format, and outputs the signal to the control section 21 .

The notification unit 24 can notify the user by any means. The notification unit 24 is a display unit that performs display based on a display signal output from the control unit 21, for example. The display section is composed of, for example, a liquid crystal display or an organic EL display.

The operation unit 25 is an interface for the user to input a destination floor. In this embodiment, as the operation unit 25, for example, a numeric keypad is used as shown in FIG. The operation unit 25 outputs a signal corresponding to the operation content of the operation unit 25 to the control unit 21. Note that the display section of the notification section 24 and the operation section 25 may be integrally configured as a touch panel display device.

1-4. Configuration of Elevator Control Device FIG. 3 is a block diagram showing the configuration of the elevator control device 30 of the elevator group management system 1 according to the present embodiment. Since the elevator control devices 30A to 30F each have the same configuration, they will be simply described as the elevator control device 30.

Like the group management control device 10 shown in FIG. 1, the elevator control device 30 includes hardware resources such as a control section 31, a storage section 32, and an input/output interface 33. The control unit 31 of the elevator control device 30 controls the operation of the elevator control device 30. The control unit 31 is configured to be able to communicate with the storage unit 32, and realizes various functions in the control unit 31 by reading and executing arithmetic programs and the like stored in the storage unit 32.

Further, the control unit 31 is configured to be able to acquire information indicating the weight inside the car of the elevator 40 measured by the weight sensor of the elevator 40 from the elevator 40 via the input/output interface 33 . The control unit 31 can determine the occupancy rate condition among the speed-up driving conditions described below based on the acquired weight. The control unit 31 may be configured similarly to the control unit 11 described above.

The elevator control devices 30A to 30F drive and control the corresponding elevators 40A to 40F, respectively, in accordance with the assigned call signal from the group management control device 10. In addition, each of the elevator control devices 30A to 30F detects the car status of the corresponding elevator 40A to 40F, including the position, running direction, door opening/closing status, load, etc., and includes information indicating the detected car status. The car status signal may be output to the group management control device 10.

2. Operation The operation of the elevator group management system 1 according to the present embodiment will be explained. In this system 1, the destination floor registration device 20 receives a destination floor registration operation by the user through the operation unit 25. The user registers a destination floor name indicating a desired destination floor by operating the operation unit 25. The group management control device 10 controls the operation of each elevator 40 based on the registered destination floor call through data communication with the destination floor registration device 20 and the elevator control device 30.

In this embodiment, each elevator 40 is managed by the group management system 1 so that when a predetermined speed-up operation condition is satisfied, the elevator 40 performs a speed-up operation that is faster than when the condition is not satisfied. Ru. If the frequency of speed-up operation of the elevator 40 can be increased, the operating efficiency of the elevator system 100 can be improved. Below, an example of the operation will be described when the speed-up operation conditions are a occupancy rate of 40% or more and 60% or less, a travel distance of 5 floors or more, and a car capacity of 20 people.

Conventionally, in elevator systems that employ a destination floor registration method, a selective collective method has been widely used as a method for allocating registered destination floors. The selective collective system is a system based on the premise that the user boards an elevator that departs in the same direction as the user's departure floor toward the destination floor (that is, the destination direction). However, these conventional methods have problems in terms of opportunities for speed-up operation, for example as described below.

FIG. 4 is a diagram for explaining the problems of the conventional elevator system. FIG. 4(a) shows an example of a situation in which a user waits for an elevator. FIG. 4(b) shows a conventional elevator operation diagram for the example of FIG. 4(a).

Figure 4(a) shows that in an elevator system installed in a building with 1st to 8th floors, seven users from the 1st floor register a destination floor call for the 7th floor, and then A situation in which one user registers a destination floor call heading for the 6th floor will be exemplified. Furthermore, in the example of FIG. 4(a), it is assumed that the elevator (car) to which the above destination floor call is assigned is currently located on the 7th floor.

In the situation shown in FIG. 4(a), the conventional elevator first descends from the seventh floor to the first floor in order to board the user on the first floor, as shown in FIG. 4(b). Next, in the process of ascending from the 1st floor to the 7th floor, the elevator stops at the 2nd floor to pick up a user heading from the 2nd floor to the 6th floor, and stops at the 6th floor to let the user get off. . In this case, the number of users (i.e., passengers) riding in the elevator is 7 in the traveling section A1 from the 1st floor to the 2nd floor, and 8 in the traveling section A2 from the 2nd floor to the 6th floor. , there are 7 people in traveling section A3 from the 6th floor to the 7th floor.

In the examples shown in FIGS. 4A and 4B, the occupancy rate condition under the speed-up driving condition is satisfied only in the traveling section A2 with eight passengers. However, in this travel section A2, the travel distance of the elevator is four floors from the second floor to the sixth floor, and the travel distance condition is not satisfied. Therefore, in the conventional system, speed-up operation cannot be performed in a situation such as that shown in FIG. 4(a).

Therefore, the elevator group management system 1 according to the present embodiment adopts a reverse direction boarding permission method in order to enable speed-up operation even in a situation where speed-up operation cannot be performed using the conventional method as described above. Adopt. The reverse direction boarding permission method is an allocation method that allows a user to board an elevator 40 operating in the opposite direction to the destination direction (hereinafter referred to as "reverse direction boarding"). An overview of the operation of this system 1 will be explained using FIG. 5.

FIG. 5 is a diagram for explaining an overview of the operation of the elevator group management system 1 according to the present embodiment. FIG. 5(a) illustrates a situation in which a user waits for the elevator 40, similar to the example of FIG. 4(a). FIG. 5(b) shows an operation diagram of the elevator 40 of this embodiment for the example of FIG. 5(a). In addition, in FIG. 5(b), the conventional system operation diagram (FIG. 4(b)) is also shown with a broken line.

In the situation shown in FIG. 5(a) (same as FIG. 4(a)), the elevator group management system 1 according to the present embodiment allows users to wait on the second floor according to the reverse direction boarding permission method. A destination floor call is assigned to an elevator 40 operating in a direction opposite to the destination direction (hereinafter referred to as "reverse direction assignment").

As shown in FIG. 5(b), the elevator 40 according to the present embodiment, as shown in FIG. It stops on the first floor, and then stops on the first floor. Next, the elevator 40 ascends from the first floor and sequentially stops at the sixth and seventh floors, which are the destination floors of each passenger. In this case, the number of passengers in the elevator 40 is 1 in the running section B1 from the 2nd floor to the 1st floor, 8 passengers in the running section B2 from the 1st floor to the 6th floor, and 8 passengers in the running section B2 from the 6th floor to the 7th floor. There are 7 people in section B3.

In the examples shown in FIGS. 5(a) and 5(b), the operation of the elevator 40 in this embodiment differs from the conventional operation in that the elevator 40 travels in a direction opposite to the direction of the passenger's destination in a part of the traveling section B1. (See the broken line in FIG. 5(b)). Further, after the traveling section B1 of such reverse direction boarding, both the occupancy rate condition and the traveling distance condition are satisfied in the traveling section B2 heading toward the passenger's destination floor. Therefore, the elevator 40 of this embodiment can perform speed-up operation in the travel section B1. As a result, in the example of FIG. 5(b), the elevator 40 is able to arrive at the destination floor (6th and 7th floor) earlier than in the conventional system.

The elevator group management system 1 according to the present embodiment operates in such a way that when the traveling section B2 in which the speed-up operation condition is satisfied as described above is predicted, the traveling section B1 for boarding in the opposite direction is allowed. Performs allocation processing applying the boarding permission method. Thereby, the present system 1 can increase the chances of speed-up operation compared to the conventional system, and can improve the operation efficiency of the elevator system 100. The details of the operation of this system 1 will be explained below.

2-1. Destination Floor Call Assignment Process In this system 1, an example of an operation in which the group management control device 10 performs an assignment process in response to a destination floor call newly registered in the destination floor registration device 20 (that is, a new call) is shown in FIG. 6 will be used for explanation. FIG. 6 is a flowchart showing an example of the allocation process of the group management control device 10 in this embodiment.

In this embodiment, the first floor (lobby floor) is set in advance as a standard floor for determining speed-up operation conditions, and the operation in which speed-up operation is applied to traveling upward from the reference floor is described. Explain an example. Each process shown in the flowchart of FIG. 6 is executed by, for example, the control unit 11 of the group management control device 10.

First, the control unit 11 of the group management control device 10 determines whether an allocation request signal has been received from the destination floor registration device 20 via the input/output interface 13 (S11). When the control unit 11 determines that the allocation request signal has not been received (S11: NO), the control unit 11 executes the determination in step S11 again.

Regarding step S11, when a new call is registered by the user's operation in the destination floor registration device 20, the control unit 21 of the destination floor registration device 20 sends an assignment request signal including destination floor information, departure floor information, and identification information. generate. The destination floor information indicates the destination floor registered by the user. The departure floor information indicates, for example, the installation floor of the destination floor registration device 20 on which the operation was performed, as the departure floor at which the user gets on the elevator 40. The identification information is information for identifying the destination floor registration device 20. The control unit 21 of the destination floor registration device 20 transmits the generated assignment request signal to the group management control device 10.

When the control unit 11 determines that an allocation request signal has been received from the destination floor registration device 20 (S11: YES), the control unit 11 selects the next floor based on departure floor information and destination floor information included in the received allocation request signal. It is determined whether formula (1) is satisfied (S12).
Destination floor > Departure floor > Standard floor…(1)

In other words, as in the above equation (1), the control unit 11 determines that the destination floor indicated by the destination floor information in the allocation request signal is a floor higher than the departure floor indicated by the departure floor information, and the departure floor is the reference floor. It is determined whether the floor is higher than the floor (S12). The judgment in step S12 is made in order to confirm whether or not the destination direction is upward in the new call corresponding to the received allocation request signal, and whether or not it is possible to go from the departure floor to the reference floor by traveling downward in the opposite direction. It will be done. For example, in the example of FIG. 5, the determination in step S12 when the user waiting on the first floor registers the destination floor call is NO, and the determination in step S12 when the user waiting on the second floor registers the destination floor call is NO. YES.

If the above formula (1) is not satisfied (S12: NO), the control unit 11 determines the allocated car number to be allocated to the new call using a normal allocation method that does not perform backward allocation (S13). In this case, the destination direction of the new call is downward, or the downward direction from the departure floor does not lead to the reference floor, so in this embodiment, the new call is particularly subject to reverse direction assignment. do not. Step S13 is performed, for example, by selecting an optimal car from all the cars as the assigned car, using arithmetic processing based on the selective collective method or the like.

Thereafter, the control unit 11 generates an allocated car signal indicating the determined allocated car, and transmits the generated allocated car signal to the destination floor registration device 20 that is the source of the allocation request signal (S14). When the control unit 21 of the destination floor registration device 20 receives the allocated car signal from the group management control device 10 as a response to the transmission of the above-mentioned allocation request signal, the control unit 21 selects the destination floor registered by the user and the information contained in the allocated car information. The information indicating the allocated car number is displayed on the notification unit 24. As a result, the destination floor registration device 20 notifies the user that the registered destination floor has been assigned to the displayed assigned car number.

Further, the control unit 11 generates an assigned call signal regarding the departure floor and destination floor of the new call, and transmits the generated assigned call signal to the elevator control device 30 of the determined assigned car (S15). The control unit 31 of the elevator control device 30 drives and controls the operation of the elevator 40 based on the assigned call signal received from the group management control device 10. According to the assigned call signal transmitted in step S15, the elevator 40 is operated in the direction of the user's destination.

On the other hand, if the above formula (1) is satisfied (S12: YES), the control unit 11 performs backward allocation determination processing based on the received allocation request signal (S16). The backward allocation determination process (S16) is a process of determining whether there is a car among all the cars 40A to 40F that is a candidate for applying the backward allocation, for example, by predicting whether or not speed-up operation is possible. Details of the backward allocation determination process will be described later (S16).

The control unit 11 determines whether there is a candidate car based on the result of the backward allocation determination process (S16) (S17).

If there is a candidate car for backward allocation (S17: YES), the control unit 11 determines the allocated car to which the new call of the allocation request signal is to be assigned from among the candidate cars for backward allocation (S18). If there are a plurality of candidate cars, in step S18, the control unit 11 can select the most suitable candidate car from among the plurality of candidate cars as the allocated car, for example, using arithmetic processing based on the reverse direction boarding permission system.

Thereafter, the control unit 11 generates, for example, an assigned car signal indicating the assigned car so as to include the reverse direction boarding information, and sends the assigned car signal including the reverse direction boarding information to the destination floor registration device 20, which is the transmission source of the allocation request signal. The machine number signal is transmitted (S19). For example, the reverse direction boarding information indicates the direction opposite to the destination direction of the new call, as the traveling direction of the assigned car when the user boards the vehicle in the reverse direction.

When the control unit 21 of the destination floor registration device 20 receives the assigned car signal in step S19, it sends information to the notifying unit 24 for guiding the user to board in the opposite direction, along with the assigned car signal similar to that in step S14, for example. to be displayed. The guide information of the reverse direction information notified by the destination floor registration device 20 in this way indicates the traveling direction of the assigned car when the user gets on board.

Further, the control unit 11 generates an assigned call signal similar to step S15 so as to include the reverse direction stop command, and transmits the assigned call signal including the reverse direction stop command to the elevator control device 30 of the determined assigned machine. (S20). The reverse direction stop command is a command to stop the assigned aircraft at the departure floor or the like while it is operating in the direction opposite to the destination direction of the new call in the operation of the allocated aircraft based on the reverse direction assignment.

When the control unit 31 of the elevator control device 30 receives the assigned call signal in step S20, it sets the timing for stopping at the departure floor of the new call in the direction opposite to the destination direction based on the reverse direction stop command. In this case, for example, when the elevator 40 travels from the reference floor after boarding in the opposite direction, speed-up operation may be performed. Details of the operation of the elevator control device 30 will be described later.

On the other hand, if there is no candidate machine for backward allocation (S17: NO), the control unit 11 performs steps S13 to S15 using the above-described normal allocation method. The assigned car signal in step S14 does not particularly include reverse direction boarding information. Further, the assigned call signal in step S15 does not particularly include a reverse direction stop command.

For example, after transmitting the allocation call signal to the elevator control device 30 (S15, S20), the control unit 11 ends the allocation process shown in the flowchart of FIG.

According to the above allocation process, if the new call can be a target for backward allocation (S12: YES), the control unit 11 performs the process of step S16 to determine whether there is a candidate machine for backward allocation. (S17). If there is a candidate car (S17: YES), the optimum car is selected as the allocated car from among the candidate cars by applying the reverse direction permissible boarding system (S18). In this way, when a destination floor call is registered by a user, the destination floor call can be preferentially assigned to a car that is predicted to be able to operate at increased speed by boarding in the opposite direction. Thereby, the group management system 1 can increase the frequency of speed-up operation of the elevator 40.

Further, upon receiving the assigned car signal through the process of step S19, the destination floor registration device 20 notifies the user of the assigned car to which the new call has been assigned as well as information for guiding boarding in the opposite direction. Thereby, even if the group management system 1 assigns a car that travels in the opposite direction to the user's destination, it can encourage the user to board the car.

2-1-1. Reverse Allocation Determination Process Next, the backward allocation determination process in step S16 in FIG. 6 will be described. FIG. 7 is a flowchart illustrating an example of backward assignment determination processing by the group management control device 10.

First, the control unit 11 sets the machine number c (S31). The car number c is set within the range of c=1 to 6, for example, corresponding to the six elevators 40A to 40F, A to F. For example, the control unit 11 sets the machine number c=1 in step S31 for the first time, and sequentially increments the machine number c in subsequent steps S31. Hereinafter, the elevator 40 with car number c will also be referred to as "c car." The c-th car is an example of a specific car that can be the target of backward allocation in this embodiment.

Next, the control unit 11 refers to the operation information stored in the storage unit 12 of the group management control device 10, for example, and determines that the call assignment with the reference floor as the departure floor (that is, the operation schedule to the reference floor) is c. It is determined whether it is registered in the machine number (S32). The determination in step S32 is made to confirm whether or not a user who is scheduled to board the car No. c is waiting on the standard floor.

If the service schedule to the standard floor is not registered for car No. c (S32: NO), the control unit 11 determines that Car No. c is not a candidate car for reverse direction allocation for a new call (S33).

If the service schedule to the standard floor is registered for the car No. c (S32: YES), the control unit 11 determines whether the No. c car is in the ascending operation state, for example, based on the operation information of the No. c car. (S34). The operating state during upward movement includes a state in which the elevator 40 is moving upward, and a state in which the elevator 40 has stopped during upward movement.

If the car No. c is not in the operating state in which the car is ascending (S34: NO), the control unit 11 determines whether the car in the car c is in the operating state in which the car is descending, based on the current car state obtained from the elevator control device 30 of the car c, for example. In this state, it is determined whether the current floor is higher than the departure floor (S35). The operating state during descent includes a state in which the elevator 40 is traveling downward and a state in which the elevator 40 is stopped in the middle of traveling downward. The current floor is the floor where the car of the elevator 40 is currently located, and is not limited to the floor where the car is stopped, but may be the closest floor where the car is running.

If the current floor is not a floor higher than the departure floor in the operating state where the c-th car is descending (S35: NO), the control unit 11 determines that the c-th car is not a candidate car for backward allocation (S33).

If the C unit is in the operating state of ascending (S34: YES), or if the current floor is higher than the departure floor in the descending operating state (S35: YES), the C unit is in the scheduled operating state. The train can stop at the departure floor before stopping at the standard floor. In such a case, the control unit 11 performs various condition determinations to predict whether car No. c can perform speed-up operation on the reference floor (S36 to S39).

For example, the control unit 11 determines whether the following formula (21) is satisfied (i.e., the next stop from the standard floor) based on the floor where the c car is scheduled to stop next to the standard floor (i.e., the next scheduled stop floor). It is determined whether the difference up to the scheduled stop floor is greater than or equal to a predetermined number of floors FL (S36).
Next scheduled stop floor - standard floor ≧ FL...(21)

In the above equation (21), the predetermined number of floors FL indicates the threshold distance of the travel distance condition under the speed-up driving condition, and is, for example, 5 floors, but is not particularly limited thereto. In step S36, the control unit 11 refers to, for example, the lowest floor among the floors scheduled to stop after the reference floor in the operation information of car No. c, as the next scheduled stop floor.

If the above formula (21) is not satisfied (S36: NO), the control unit 11 determines that the c-th car is not a candidate car for backward allocation (S33).

If the above formula (21) is satisfied (S36: YES), the control unit 11 determines whether the following formula (22) is satisfied (that is, whether the difference from the reference floor to the destination floor is greater than or equal to the predetermined number of floors FL) is determined (S37).
Destination floor - reference floor ≧FL...(22)

According to steps S36 and S37, when a new call is assigned to car No. c, it can be predicted whether or not the mileage condition under the speed-up driving condition will be satisfied on the reference floor.

If the above formula (22) is not satisfied (S37: NO), the control unit 11 determines that the c-th car is not a candidate car for backward allocation (S33).

If the above formula (22) is satisfied (S37: YES), the control unit 11 determines whether the following formula (23) regarding the lower limit of the occupancy rate condition for car No. c on the reference floor is satisfied (S38).
Standard floor departure number of people ≧Pmin×P…(23)

In the above equation (23), the number of passengers departing from the standard floor is the number of passengers scheduled to arrive when the C-car departs from the standard floor, excluding, for example, new call users. The number of people can be calculated, for example, based on the call assignment for car No. c. The lower limit number of people Pmin is the lower limit number of people under the occupancy rate condition, and is, for example, eight people, but is not particularly limited to this. The predetermined coefficient P is a positive value less than 1, such as 0.7, 0.8, 0.9, etc., but is not limited thereto.

The above equation (23) indicates a condition in which the number of people departing from the standard floor is larger than a threshold value Pmin×P (an example of a first threshold value) obtained by lowering the lower limit number of people Pmin in the occupancy rate condition by multiplying it by a predetermined coefficient P. The judgment in step S38 based on the above formula (23) is that the number of people departing from the standard floor before the new call assignment is greater than or equal to the number of people who are predicted to be able to perform speed-up operation from the standard floor by boarding in the future. This is done to narrow down candidate machines for backward allocation.

If the above formula (23) regarding the lower limit of the occupancy rate condition is not satisfied (S38: NO), the control unit 11 determines that the c-car is not a candidate car for backward allocation (S33).

If the above formula (23) regarding the lower limit of the occupancy rate condition is satisfied (S38: YES), the control unit 11 determines whether the following formula (24) regarding the upper limit of the occupancy rate condition of car c on the standard floor is satisfied (S39 ).
Standard floor departure number +1≦Pmax…(24)

In the above formula (24), the upper limit number of people Pmax is the maximum number of people under the occupancy rate condition, and is, for example, 12 people, but is not particularly limited to this. The left side of the above equation (24) shows that the number of people departing from the standard floor is increased by one person in accordance with the number of new users. The above equation (24) indicates a condition in which the number of people who take into account the number of people departing from the standard floor by taking into account the increase in number of people boarding in the opposite direction is smaller than the upper limit number of people Pmax (an example of the second threshold value) in the occupancy rate condition. The judgment in step S39 based on the above formula (24) is that if a new call is assigned, the number of passengers departing from the standard floor is so large that it is predicted that speed-up operation will not be possible. This is done to exclude the machine from the candidates for backward allocation.

If the above formula (24) regarding the upper limit of the occupancy rate condition is not satisfied (S39: NO), the control unit 11 determines that the c-car is not a candidate car for backward allocation (S33).

If the above formula (24) regarding the upper limit of the occupancy rate condition is satisfied (S39: YES), the control unit 11 determines that car No. c is a candidate car (S40). For example, the control unit 11 sets the flags (referred to as Rf[1] to Rf[6]) for each machine to manage whether or not all machines 40A to 40F are candidates for backward allocation to the machine c. Flag Rf[c] is set to ON (S40). The initial value of each of the flags Rf[1] to Rf[6] is set to OFF, for example, before the start of the backward allocation determination process (S16). Further, when it is determined that the c-th car is not a candidate car, the corresponding flag Rf[c] is maintained at OFF.

When it is determined whether car No. c is a candidate car for backward allocation (S33, S40), the control unit 11 determines whether the determination for all cars 40A to 40F has been completed (S41). If the determination has not been completed for all the machines 40A to 40F (S41: NO), the control unit 11 sets the machine number c to the undetermined machine in step S31, and performs the processing from step S32 onwards.

If the determination for all machines 40A to 40F is completed (S41: YES), the control unit 11 ends the backward allocation determination process (S16). After that, step S17 in FIG. 6 is performed.

According to the above backward allocation determination process (S16), when the new call is assigned to a specific car, it is predicted whether or not the car satisfies the mileage condition through the processes of steps S36 to S37. Furthermore, through the processing in steps S38 to S39, it is predicted whether or not the car in question satisfies the occupancy rate condition, for example, based on the number of passengers instead of the actual weight in the car. The control unit 11 determines whether or not the speed-up operation conditions will be satisfied when such a new call is assigned by backward assignment, and selects candidate machines for reverse assignment for the new call in which each of the machines 40A to 40F is registered. It can be determined whether or not.

In addition, if the process in step S39 predicts that the number of passengers departing from the standard floor will exceed the upper limit of the occupancy rate condition when a new call is assigned to a specific car (S39: NO), then is determined not to be a candidate machine for backward allocation (S33). Thereby, it is possible to avoid a situation where a car that is predicted to already satisfy the speed-up operation condition no longer satisfies the occupancy rate condition and, by extension, the speed-up operation condition when a new call is assigned. Therefore, the group management system 1 can suppress a decrease in the frequency of speed-up operation of the elevator 40.

The process of step S37 described above is not limited to particularly between steps S31 to S41, and may be performed, for example, before step S31. In this case, the control unit 11 executes the subsequent steps S31 to S41 only for the car that satisfies the above equation (22) in step S37.

Further, the threshold value in step S38 is not limited to multiplying the above-mentioned lower limit number of people Pmin by a predetermined coefficient P, and various settings are possible. For example, the threshold value may be set by subtracting a predetermined number (for example, 1 or 2) from the lower limit number of people Pmin instead of the right side of the above equation (23). Further, the lower limit value in step S38 does not necessarily have to be relaxed from the occupancy rate condition, and may be the same as the lower limit number of people Pmin.

2-2. Operation of Elevator Control Device The operation of the elevator control device 30 in the present system 1 will be explained using FIGS. 8 and 9. Below, an example of the operation of the elevator control device 30 in which the speed-up operation is not limited to upward from the first floor will be described.

2-2-1. Setting Process of Elevator Control Device FIG. 8 is a flowchart showing an example of a setting process in the elevator control device 30. The setting process shown in the flowchart of FIG. 8 is executed by the control units 31A to 31F of any of the elevator control devices 30A to 30F. Below, as an example, an example in which the control unit 31A of the elevator control device 30A that controls car A performs the setting process will be described.

The setting process illustrated in FIG. 8 is started with stop schedule flags Sp[f][D] for each floor and vertical direction stored in the storage unit 32 of the elevator control device 30, and is executed periodically, for example. Ru. The stop schedule flag Sp[f][D] is a flag that indicates ON/OFF whether there is a plan to stop at the f floor, and is a flag that indicates whether or not there is a plan to stop at the f floor. and the running of the vehicle are managed separately. For example, if Car No. A is scheduled to stop at floor f and then travel upward, Sp[f][UP] is set to "ON" in advance.

First, the control unit 31A of the elevator control device 30A determines whether an assignment call signal has been received from the group management control device 10 (S51).

When the control unit 31A determines that the allocation call signal has not been received (S51: NO), the control unit 31A determines whether the A car is on any floor (referred to as the "F floor") based on the current running state of the A car. It is determined whether the vehicle has stopped in the direction (S52). For example, when the A car is scheduled to stop on the F floor and then travel upward or downward, the determination in step S52 will be YES.

When the control unit 31A determines that the A car has stopped on the F floor heading in the D direction (S52: YES), it sets the stop schedule flag Sp[F][D] to "OFF" (S53), and in step S51 Return to In step S53, the setting of the planned stop on the F floor in the D direction is reset in accordance with the completion of that plan.

On the other hand, if the control unit 31A determines that the A car is not stopped on the F floor heading in the D direction (S52: NO), the control unit 31A does not particularly change the settings of the stop schedule flags Sp[F][D] and steps Return to S51.

When the control unit 31A determines that the assigned call signal has been received (S51: YES), the control unit 31A determines whether the received assigned call signal includes a reverse direction stop command (S54).

If the assigned call signal does not include a reverse direction stop command (S54: NO), the control unit 31A determines whether the destination floor is higher than the departure floor based on the departure floor and destination floor included in the assigned call signal. It is determined whether or not (S55).

If the destination floor is higher than the departure floor (S55: YES), the control unit 31A sets the upward stop schedule flag Sp[f=departure floor][UP] to "ON" for the departure floor. (S56). As a result, a schedule is set in which the A-car stops at the departure floor and then travels upward in the same direction as the passenger's destination.

If the destination floor is not a floor above the departure floor (S55: NO), the control unit 31A sets the downward stop schedule flag Sp[f=departure floor][DOWN] to "ON" for the departure floor. (S57). As a result, a schedule is set in which the A-car stops at the departure floor and then travels downward in the same direction as the passenger's destination.

When the assigned call signal includes a reverse direction stop command (S54: YES), the control unit 31A determines whether the destination floor is a floor higher than the departure floor based on the departure floor and destination floor included in the assigned call signal. It is determined whether there is one (S58).

If the destination floor is higher than the departure floor (S58: YES), the downward stop schedule flag Sp[f=departure floor][DOWN] is set to "ON" for the departure floor (S59). As a result, a schedule is set in which the A-car stops at the departure floor and then travels downward in the opposite direction to the passenger's destination.

If the destination floor is not a floor higher than the departure floor (S58: NO), the control unit 31A sets the upward stop schedule flag Sp[f=departure floor][UP] to "ON" for the departure floor. (S60). As a result, a schedule is set in which the A-car stops at the departure floor and then travels upward in the opposite direction to the passenger's destination.

After executing steps S56, S57, S59, or S60, the elevator control device 30A ends the setting process for the received assignment call signal. When the process ends, the control unit 31A returns to step S51 and determines whether another allocation call signal has been received.

According to the above setting process in the elevator control device 30, when the received assigned call signal includes a reverse direction stop command (S54: NO), the control unit 31 controls the elevator 40 to be operated in the reverse direction by the process from step S58 onwards. The boarding direction can be set to stop at the passenger's departure floor.

2-2-2. Operation Control of Elevator Control Device With the scheduled stop floor of the elevator 40 set as described above, the elevator control device 30 determines whether or not the speed-up operation condition is satisfied and controls the running of the elevator 40. An example will be explained using FIG. 9.

FIG. 9 is a flowchart illustrating the operation control of the elevator 40 in the elevator control device 30. The process shown in the flowchart of FIG. 9 is executed by the control units 31A to 31F of any of the elevator control devices 30A to 30F, as in FIG. 8, and an example in which car A is run will be described below.

First, the control unit 31A determines whether departure preparations for aircraft A have been completed (S71). Preparation for departure includes, for example, closing the car door in a state where Car A has stopped at an arbitrary floor and the next planned stop floor has been determined. When the control unit 31A determines that preparations for departure are not completed (S71: NO), the control unit 31A executes the determination in step S71 again.

When the control unit 31A determines that preparations for departure have been completed (S71: YES), the control unit 31A obtains information indicating the current weight in the car of car A, for example, and determines that the weight in the car of car A is within a predetermined range. It is determined whether or not (S72). That is, in step S72, the control unit 31A determines whether the weight in the car of car A satisfies the occupancy rate condition under the speed-up operation condition.

If the weight in the car is not within the predetermined range (S72: NO), car A does not satisfy the speed-up operation conditions. In this case, the control unit 31A causes the car A to travel so that the car runs from the current floor to the next scheduled stop floor in normal operation rather than speed-up operation (S73).

If the weight in the car is within the predetermined range (S72: YES), Car A satisfies the occupancy rate condition among the speed-up operation conditions. In this case, the control unit 31A determines whether the travel distance between the current floor and the next scheduled stop floor is equal to or greater than the predetermined floor FL (S74). That is, in step S74, the control unit 31A determines whether or not the travel distance condition is satisfied for the travel section in which the A car will travel from now on.

If the traveling distance between the current floor and the next scheduled stop floor is not equal to or greater than the predetermined floor FL (S74: NO), the A car does not satisfy the speed-up operation conditions. In this case, the control unit 31A causes the car No. A to travel in normal operation to the next scheduled stop floor (S73).

If the travel distance between the current floor and the next scheduled stop floor is equal to or greater than the predetermined floor FL (S74: YES), the A car satisfies the speed-up operation conditions. Therefore, in this case, the control unit 31A causes the car A to travel so that the car runs at increased speed from the current floor to the next scheduled stop floor (S75).

The control unit 31A causes the car No. A to travel in normal operation or speed-up operation (S73 or S75), and ends the process shown in the flowchart of FIG. 9. Thereafter, when the A-car stops at the scheduled stop floor, the control unit 31A executes the process again from step S71.

According to the above-described operation control in the elevator control device 30, the control unit 31 determines whether or not the occupancy rate condition is satisfied based on the actual weight in the car before the departure of the elevator 40 (S72). The sufficiency of the up-operation conditions can be determined with high accuracy. According to such a determination, the elevator control device 30 switches whether to operate the elevator 40 between normal operation and speed-up operation (S72, S74).

3. Summary As explained above, the elevator group management system 1 according to the present embodiment is an elevator that can perform speed-up operation in which the elevator runs at a speed faster than the rated speed in a travel section that satisfies predetermined speed-up operation conditions. The group management system 1 includes a destination floor registration device 20 for a user to register a destination floor call indicating a desired destination floor, and a destination floor call registered by the user with the destination floor registration device 20. and a control device 10 that allocates a destination floor call to one of the plurality of elevators 40 based on the destination floor call. , when a user gets on a train that travels in the opposite direction from the user's departure floor to the destination floor, it predicts whether or not the speed-up driving conditions will be met, and depending on the prediction result, , controls whether or not the elevator 40 operates in the opposite direction.

Thereby, the elevator group management system 1 according to the present embodiment determines whether or not to operate the elevator in the opposite direction depending on the prediction result of whether or not the speed-up operation condition is satisfied when the user gets on the train in the opposite direction. control. As a result, the present system 1 can increase the opportunity to run the elevator at a speed faster than the rated speed (that is, the opportunity to perform speed-up operation) in the variable speed elevator by using the reverse direction boarding permission method.

Further, in the elevator group management system 1 according to the present embodiment, when the control device 10 predicts that the speed-up operation condition will be satisfied, the control device 10 assigns a destination floor call candidate ( In other words, the destination car may be classified into candidate cars, and the assigned car to which the destination floor call is assigned may be determined from among the candidates.

As a result, if there is a car in which the speed-up driving condition is predicted to be satisfied if the user rides in the opposite direction, the system 1 assigns the destination floor name registered by the user to one of such cars. . Therefore, the group management system 1 can increase the frequency of speed-up driving using the reverse direction boarding allowance method.

Furthermore, in the elevator group management system 1 according to the present embodiment, if the control device 10 predicts that the speed-up operation condition will not be met, the control device 10 can call the destination floor from a plurality of elevators without using operation in the opposite direction. The allocated machine number to be allocated may be determined.

As a result, this system 1 allows the user to board in the opposite direction, but for destination floor calls for which there is no car that can perform speed-up operation, the system 1 assigns the most suitable car to the destination floor without assigning the reverse direction. Calls can be assigned and group management control of the elevator system 100 can be performed.

In the elevator group management system 1 according to the present embodiment, the speed-up operation conditions include that the occupancy rate of a specific car on a predetermined standard floor is within a predetermined range, and that the standard floor and the next The travel distance between the specific car and the scheduled stop floor at which the specific car stops may be equal to or greater than a threshold distance.

Thereby, the present system 1 controls whether or not to perform speed-up operation for a specific elevator 40 based on the occupancy rate of the specific elevator 40 and the distance traveled by the specific elevator. For example, the present system 1 is configured to perform speed-up operation when the hoisting machine of the elevator 40 has surplus output and the elevator 40 is traveling in a section having a distance long enough to travel at a speed higher than the rated speed. Elevator 40 can be controlled.

Further, in the elevator group management system 1 according to the present embodiment, the control device 10 determines the occupancy rate of a specific car on a reference floor and the lower limit of a predetermined range when boarding of users in the opposite direction is not considered. It may be predicted whether or not the speed-up driving condition is satisfied by comparing the first threshold value which is smaller than the first threshold value.

As a result, if the occupancy rate of a specific car when the user does not board the specific car exceeds the first threshold value, which is smaller than the lower limit of the predetermined range of the occupancy rate condition, the system 1 will It is possible to predict that the occupancy rate may exceed the lower limit. Thereby, the present system 1 can secure opportunities to perform speed-up operation and increase the frequency thereof.

Further, in the elevator group management system 1 according to the present embodiment, the control device 10 determines the occupancy rate of a specific car on a reference floor and the upper limit of a predetermined range when boarding of users in the opposite direction is taken into consideration. It may be predicted whether or not the speed-up driving condition is satisfied by comparing the speed-up driving condition with a second threshold value indicating the speed-up driving condition.

As a result, the present system 1 calculates the possibility that the speed-up driving condition will be satisfied as long as the occupancy rate when the user gets on a specific car does not exceed the second threshold value indicating the upper limit of the predetermined range of the occupancy rate condition. Can be predicted. Thereby, the present system 1 can improve the operating efficiency of the elevator system 100 by speeding up operation.

Further, in the elevator group management system 1 according to the present embodiment, the control device 10 may exclude from the above candidates, among the plurality of elevators, the occupancy rate on the reference floor exceeds the second threshold value. .

As a result, if there is a car whose occupancy rate exceeds the second threshold when the destination floor call is assigned, this system 1 can preferentially allocate the destination floor call to a car other than the concerned car in the reverse direction allocation. . Therefore, the present system 1 can suppress a situation in which a new destination floor call is assigned to a car for which speed-up operation is already predicted to be possible due to reverse direction assignment, thereby making speed-up operation impossible. Therefore, the system 1 can increase the frequency of speed-up operation.

Further, in the elevator group management system 1 according to the present embodiment, the destination floor registration device 20 includes a notification unit 24 that notifies users of the assigned car number, and the control device 10 operates the assigned car number in the opposite direction. If it is determined to proceed in the opposite direction, the notification unit 24 may notify that the assigned car will proceed in the opposite direction.

Thereby, when the user rides in the opposite direction, the system 1 notifies the user that the assigned car will be traveling in the opposite direction to the destination direction. This allows the user to know in advance that the car he or she is boarding will be traveling in the opposite direction to the destination, before boarding the vehicle. Therefore, this system 1 can improve convenience for users.

Further, the elevator group management system 1 according to the present embodiment further includes an elevator control device 30 that controls the operation of a predetermined number of elevators 40, and the elevator control device 30 is configured to control the operation of a predetermined number of elevators in accordance with speed-up operation conditions. Depending on whether or not the conditions are met, it may be possible to switch whether or not to operate a predetermined machine at increased speed.

As a result, when controlling the operation of a predetermined machine, the system 1 can switch whether or not to operate the machine in speed-up operation depending on whether the machine satisfies the speed-up operation condition. I can do it. For example, the group management system 1 more reliably performs speed-up operation when the hoisting machine of the elevator 40 has surplus output and is traveling in a section that is long enough to travel at a speed higher than the rated speed. The elevator 40 can be controlled to perform the following steps.

The elevator group management method according to the present embodiment is capable of executing speed-up operation in which elevators run at a speed higher than the rated speed in a travel section that satisfies predetermined speed-up operation conditions, and allows users to perform desired speed-up operation. Elevator group management method for allocating a destination floor call to one of a plurality of elevators 40 based on the destination floor call registered in the destination floor registration device 20 for registering the destination floor call indicating the destination floor When a user gets on a train during a service in which a specific car out of multiple cars runs in the opposite direction from the user's departure floor to the destination floor, based on the destination floor call. Then, it is predicted whether or not the speed-up operation condition is satisfied, and depending on the result of the prediction, it is controlled whether or not the elevator 40 is operated in the opposite direction.

According to such an elevator group management method, it is possible to increase the chances of speeding up operation by predicting whether or not the speeding up operation condition is satisfied when a user gets on the elevator in the opposite direction.

The computer program according to the present embodiment can cause an arithmetic circuit to execute the above elevator group management method.

In the first embodiment described above, in the assignment process of the group management control device 10, the reference floor is set to the first floor (lobby floor) as an example, but the present invention is not limited to this. For example, the reference floor may be the top floor of a building. In this case, the control unit 11 of the group management control device 10 determines the condition in which each inequality sign in equation (1) is inverted in step S12 of FIG. Allocation processing can be executed.

In the above case, the elevator group management system 1 allows the user to ride in the opposite direction when the destination direction is downward instead of the upward direction as in the first embodiment. By allocating the elevators 40 in this way, it is possible to increase the frequency of speed-up operation. In addition, in this case, in the same backward allocation determination process as in the first embodiment described above, the control unit 11 determines in step S34 whether or not the car No. c is in the descending operation state, and in step S35 whether the car No. c It is determined whether the current floor is a floor lower than the departure floor in the operating state where the train is ascending.

Further, in the elevator group management system 1 according to the present embodiment, the reference floor may be a floor other than the first floor or the top floor. Further, a plurality of reference floors may be set. The reference floor may be a floor on which the car of the elevator 40 reverses its traveling direction, for example, the second floor or another floor. Specifically, when the car of the elevator 40 stops at the second floor from the third or higher floor and ascends again to the third or higher floor, the second floor can be considered as the reference floor. Similarly, even if the building has a basement floor, the control unit 11 can perform the backward allocation determination process using, for example, the first floor as the reference floor. Further, on each reference floor, the traveling direction in which the speed-up operation can be performed can be appropriately set to one or both of the vertical directions.

In the embodiment described above, in step S38 of the backward allocation determination process (FIG. 7), the control unit 11 determines whether equation (23) is satisfied, but the present invention is not limited to this. For example, the control unit 11 may determine that the occupancy rate condition is not satisfied if the occupancy rate of car No. C when departing from the reference floor is below the lower limit of a predetermined range.

Furthermore, in the embodiment described above, in the backward allocation determination process, the control unit 11 determines whether equation (24) is satisfied, as defined in step S39 of FIG. 7, but the present invention It is not limited to this. For example, the control unit 11 may determine that the occupancy rate condition is not satisfied if the occupancy rate of car No. C when departing from the reference floor exceeds the upper limit of a predetermined range.

In the embodiment described above, the traveling distance of the traveling section is expressed, for example, by the difference in the number of floors between the current floor of the car of the elevator 40 and the next scheduled stop floor. The mileage is not limited to this. For example, depending on the building, the distance between the first and second floors may be greater than the distance between other floors. Therefore, each of the control units 11 and 31 may correct the difference in the distance between floors of the building in which the group management system 1 is located, and specify the travel distance of the travel section. Further, the travel distance of the travel section may be the inter-floor distance between the current floor and the next scheduled stop floor. In this case, each of the control units 11 and 31 can specify the travel distance of the travel section based on the distance between floors of the building where the group management system 1 is located. The difference in the distance between floors can be stored in each of the storage units 12 and 32. The predetermined threshold distance regarding the travel distance condition may also be determined in consideration of the distance between floors, similar to the travel distance of the travel section.

In the embodiment described above, if there is no candidate car that is predicted to satisfy the speed-up operation conditions, the control unit 11 selects an optimal car from among all the cars to be assigned to the destination floor call corresponding to the allocation request signal. is selected as the assigned machine number, but the present invention is not limited thereto. For example, if it is predicted that the speed-up driving condition is already satisfied for a specific car, and it is predicted that the speed-up driving condition will no longer be satisfied if the user gets on the specific car, the control unit 11 The destination floor number of the user may be assigned to a car other than the car number as much as possible. This makes it possible to preferentially allocate destination floor calls to cars other than the specific car that is predicted to already satisfy speed-up operation. Therefore, in the elevator system 100 having the group management system 1, the control unit 11 can prevent speed-up operation from becoming impossible by assigning a new destination floor call to a car for which speed-up operation is already possible. .

In the embodiment described above, a new destination floor call is registered by the user operating the destination floor registration device 20, but the present invention is not limited to this. For example, the user may register the destination floor call by operating an information terminal such as a mobile phone, smart phone, or tablet. In this case, the group management control device 10 transmits an assigned car signal to the information terminal. The information terminal can display the destination floor and the allocated car number on the display of the information terminal based on the received allocated car signal. Further, when the assigned car signal includes reverse direction boarding information, the information terminal can display the traveling direction of the assigned car on the display.

In the above-described embodiment, the notification unit 24 is a display unit, but the notification unit 24 is not limited to this. The notification section 24 may include an audio output section such as a speaker instead of or in addition to the display section. Thereby, the notification unit 24 can notify the user of the destination floor, assigned car number, and travel direction to the user not only by visual means but also by auditory means.

The elevator group management system, group management method, and computer program according to the present invention are realized by cooperation between hardware resources, such as a processor and memory, and software (computer program).
