2. Operation 2-1. Outline of Operation An outline of the operation of the elevator system according to the present embodiment will be described. In the present system, when the hall call registration device 30 receives registration of a hall call (upward or downward call), the received hall call is assigned to any of a plurality of units. Then, the assigned machine (assigned machine) is caused to travel to the floor on which the hall call is registered. When the assigned car arrives at the registered floor and the user designates the destination floor with the destination floor button in the car, the assigned car is driven to the designated destination floor.

2-2. Operation of Group Management Control Device The control unit 11 of the group management control device 10 performs a process of assigning a car to a hall call. The number assignment process is a process of assigning a hall call registered using the hall call registration device 30 to any one of the plurality of units. Specifically, when the control unit 11 receives the allocation request signal from the hall call registration device 30 via the input/output interface 13, the control unit 11 performs the allocation process of allocating the hall call to any one of the plurality of units. The allocation request signal is a signal requesting that the hall call registered by the hall call registration device 30 be assigned to any one of a plurality of machines. The allocation request signal includes information indicating the floor (registered floor) where the hall call registration operation was performed.

  The control unit 11 outputs, to the number control device 40 corresponding to the assigned number (assigned number), a control signal for instructing the assigned hall call to travel to the registered floor (departure floor) and stop at the registered floor. .. The machine control device 40 that has received the control signal from the group management control device 10 drives and controls the corresponding elevator (machine) based on the control signal from the group management control device 10.

  Here, in the elevator system of the present embodiment, the control unit 11 of the group management control device 10 uses the simple method group management control (first group management control) and the immediate forecast method group management control (second group management). Control) and can be executed. When a hall call is generated on a specific floor where a floor indicator 70 indicating the current positions of a plurality of units is arranged, the control unit 11 of the group management control device 10 uses a simple group management for the hall call. When the control is executed and the hall call occurs on a floor other than the specific floor, the group management control of the immediate forecast method is executed for the hall call. This will be described in detail below.

2-2-1. Immediate forecast system In the group supervisory control of the instant forecast system, the control unit 11 of the group supervisory control device 10 responds to the landing call of each unit based on a plurality of parameters indicating the operating state of each unit when the hall calling occurs. An evaluation value regarding allocation suitability is obtained, and a hall call is allocated to a machine having the highest evaluation value among the plurality of cars.

  Specifically, the control unit 11 of the group management control device 10 first calculates, for each of the plurality of units, an evaluation value for selecting the unit to which the hall call is assigned, based on the operation information of each unit. The operation information of each unit includes, for example, the car state (including the car position, traveling direction, door open/closed state, load, etc.) of each unit, and the response time to the hall call (from the present, the assigned unit arrives at the departure floor). It includes information indicating the time (waiting time), the number of hall calls assigned to each unit, the predicted number of passengers in each unit (car load), and the like. The response time is, for example, (1) the travel time required for the car to move from the current position to the registration floor for the hall call, and (2) the time required for the car to reach the registration floor for the hall call from the current position. The time when the car is stopped in response to a car call registered by another hall call user using the destination floor button in the car, and (3) the car arrives from the current position to the hall call registration floor. In the meantime, it can be obtained by adding up the time during which it stopped in response to a hall call on the middle floor. After the calculation of the evaluation value, the control unit 11 selects the machine having the smallest evaluation value from the plurality of machines and assigns the hall call to the selected machine.

  The control unit 11 of the group management control device 10 immediately controls the lighting of the hall lantern 80 corresponding to the assigned number on the registered floor when the number is assigned to the hall call by the group management control of the immediate forecast method. A signal is output and the hall lantern 80 is turned on.

  Further, in the group management control of the immediate forecast method, the control unit 11 of the group management control device 10 provisionally allocates each of the assigned and unanswered hall calls to each of the plurality of units at a predetermined time cycle. , Obtain the evaluation value regarding the allocation suitability of each machine, and if there is a machine with an evaluation value showing an allocation suitability higher than the evaluation value of the currently allocated machine among multiple machines, the highest allocation The allocation is changed to the machine having the evaluation value showing the highest allocation aptitude, provided that the difference between the evaluation value showing the aptitude and the evaluation value of the currently allocated machine is a predetermined value or more. In the immediate forecast method, the assigned number is guided when the hall call is registered, and if the assigned number is changed after that, the user may be confused. Therefore, the implementation of allocation change is limited only when the above conditions are met. Incidentally, instead of the condition that the difference between the evaluation value showing the highest allocation aptitude and the evaluation value of the currently allocated machine is a predetermined value or more, for example, of the machine having the evaluation value showing the highest allocation aptitude The condition may be that the response time is shorter than the response time of the assigned vehicle by a predetermined time or more. For example, the allocation change is not performed only by shortening the response time (waiting time of the user) by about 10 seconds by the allocation change, and the allocation change is performed by reducing the response time by about 1 minute. In addition, when the difference between the evaluation value indicating the highest allocation suitability and the evaluation value of the currently allocated machine is a predetermined value or more, a predetermined value, for example, the frequency of occurrence of allocation change The setting is made so that the occurrence frequency of the allocation change is approximately the same as the occurrence frequency of the allocation change when the response time is reduced by about 1 minute.

  The control unit 11 of the group management control device 10 uses the group management control of the immediate forecast method to immediately change the allocation of the car on the registered floor when the allocation of the car is changed with respect to the hall call that has been allocated and has not responded. A lighting control signal is output to the hall lantern 80 corresponding to the No. machine to light the hall lantern 80.

  In the above-described immediate forecasting method, the number of units that respond to a hall call with the shortest response time is not always assigned, but as compared with the simple method, good operation efficiency can be obtained for the entire elevator system.

2-2-2. Simplified method In the group management control of the simplified method, the control unit 11 of the group management control device 10 provisionally assigns a hall call to each of a plurality of units when a hall call is generated, and based on the operation information of each unit. , The response time (time from the current position until the assigned car arrives at the departure floor) of each car is determined, and the car call is assigned to the car with the smallest response time among the plurality of cars.

  In addition, the control unit 11 of the group management control device 10 causes the assigned number control device 40 corresponding to the assigned number (assignment number) to drive the assigned hall call to the registration floor (departure floor) and stop at the registration floor. The control signal for instructing is output.

  In the group management control of the simplified method, the control unit 11 of the group management control device 10 provisionally allocates each of the assigned and unanswered hall calls to each of the plurality of units at a predetermined time period, and then the respective units. , The response time to the hall call is determined, and if there is a machine with a response time shorter than that of the currently allocated machine among multiple machines, it is assigned to the machine with the smallest response time. Make a change. Therefore, the allocation change is relatively frequently made to the car having the minimum response time.

  Here, in the present embodiment, since the hall lantern 80 is not installed on the specific floor, guidance of the number is performed when the assigned number for the new hall call is decided or when the assignment is changed. There is no. Although the hall lantern 80 is not installed on the specific floor in the present embodiment, the hall lantern 80 may be installed on the specific floor. Then, the control unit 11 of the group management control device 10 outputs a lighting control signal to the hall lantern 80 on the specific floor immediately before the assigned number arrives at the specific floor as the registered floor, and even if the hall lantern 80 is turned on. Good.

2-3-4. Allocation change process of hall calls Call numbers for management are added to the hall calls that have been registered and have not yet responded, and the control unit 11 of the group management control device 10 individually manages each hall call that has been registered. Determine whether it is necessary to change the allocation. FIG. 5 is a flowchart illustrating the allocation changing process performed by the group management control device 10 according to the first embodiment. The process according to this flowchart is repeatedly executed at a predetermined time cycle.

  The control unit 11 of the group management control device 10 sets 1 as the call number i of the registered hall call Ci (S41).

  The control unit 11 of the group management control device 10 determines whether or not the registered floor of the hall call Ci with the call number i is the specific floor (S42).

  When the registered floor of the hall call Ci of the call number i is the specific floor (YES in S42), the control unit 11 of the group management control device 10 determines the allocation change of the hall call Ci of the call number i by a simple method ( S43).

  When the registered floor of the hall call Ci of the call number i is not the specific floor (YES in S42), the control unit 11 of the group management control device 10 determines the allocation change of the hall call Ci of the call number i by the immediate forecast method ( S44).

  The control unit 11 of the group management control device 10 sets a number obtained by adding 1 to the current call number i as a new call number i (S45).

  The control unit 11 of the group management control device 10 determines whether or not the call number i is larger than the number of machine numbers imax (S46).

  When the called number i is not larger than the number imax of the number of machines (NO in S46), the control unit 11 of the group management control device 10 repeats the processing from step S42.

Specific Processing of Allocation Change Processing by Simplified Method FIG. 6 is a flowchart illustrating specific processing of allocation change processing by the simple method performed in step S43 of FIG. 5 by the group management control device 10 according to the first embodiment. is there.

  The control unit 11 of the group management control device 10 provisionally allocates the hall calls Ci to the units 1 to n, respectively, and calculates the response times of the units 1 to n (S51).

  The control unit 11 of the group management control device 10 determines whether or not the response time of the car to which the hall call Ci is currently assigned is the minimum among the calculated response times of the cars 1 to n (S52). ..

  When the response time of the car to which the hall call Ci is currently assigned is not the minimum (NO in S52), the control unit 11 of the group management control device 10 reallocates the hall call Ci to the car having the smallest response time. (S53), the process according to the flowchart of FIG. 6 ends, and the process of step S45 of FIG. 5 is performed.

  When the response time of the car to which the hall call Ci is currently assigned is the minimum (YES in S52), the control unit 11 of the group management control device 10 ends the process according to the flowchart of FIG. 6 and proceeds to step S45 of FIG. Process. That is, the control unit 11 of the group management control device 10 does not change the allocation of the hall call Ci.

2-3-6. Specific Processing of Allocation Change Processing by Immediate Forecasting Method FIG. 7 is a flowchart for explaining specific processing of allocation change by the immediate forecasting method performed in step S44 of FIG. 5 by the group management control device 10 according to the first embodiment. Is.

  The control unit 11 of the group management control device 10 provisionally allocates the hall call Ci to the units 1 to n, and calculates the evaluation value of the units 1 to n (S61).

  The control unit 11 of the group management control device 10 determines whether or not the evaluation value of the car to which the hall call Ci is currently assigned is the smallest among the calculated evaluation values of the cars 1 to n (S62). ..

  When the evaluation value of the car to which the hall call Ci is currently assigned is not the minimum (NO in S62), the control unit 11 of the group management control device 10 causes the machine to which the minimum evaluation value and the hall call Ci are currently assigned. It is determined whether or not the difference from the evaluation value of is larger than a predetermined value (S63).

  If the difference between the evaluation values is larger than the predetermined value (YES in S63), the control unit 11 of the group management control device 10 allocates the hall call Ci to the car having the smallest evaluation value (S64), and The process according to the flowchart of FIG. 7 is ended, and the process of step S45 of FIG. 5 is performed. In addition, when the allocation is changed in step S64, the control unit 11 of the group management control device 10 immediately outputs a lighting control signal to the hall lantern 80 corresponding to the allocation change destination machine on the registered floor, and The hall lantern 80 is turned on. When the allocation is changed, needless to say, the hall lantern 80 is not turned on for the allocated number before the allocation is changed.

  When the evaluation value of the car to which the hall call Ci is currently assigned is the smallest (YES in S62), the control unit 11 of the group management control device 10 ends the process according to the flowchart of FIG. 7, and step S45 of FIG. Process. That is, the control unit 11 of the group management control device 10 does not change the allocation of the hall call Ci.

  When the difference between the evaluation values is not larger than the predetermined value (NO in S63), the control unit 11 of the group management control device 10 ends the process according to the flowchart of FIG. 7 and performs the process of step S45 of FIG. . That is, the control unit 11 of the group management control device 10 does not change the allocation of the hall call Ci. This is because, if the allocation is changed easily in the immediate forecast system, it may cause confusion for users.

3. Action As described above, the immediate forecast method has an advantage that the operation efficiency of the entire elevator system can be increased. However, in the immediate forecast system, when the user registers a new upward or downward hall call at a certain floor, the car closest to the registered floor does not always respond. Therefore, in the group management system of the immediate forecast system, if the floor indicator 70 is provided in the elevator hall, the user can visually recognize such a situation, and the visually recognizable user responds to the number of the car closest to the registered floor. You may feel strange about not doing it.

  Therefore, when the floor indicator 70 is provided, it is conceivable to adopt the above-described simple method as the group management control method of the elevator system. However, in the simple method, the number allocation is determined based only on the response time of each hall call. Therefore, if the response time of one hall call is controlled to be the shortest, the response time of other hall calls becomes long. May be. In addition, the allocation change may be repeatedly performed among a plurality of units so that the operations of the plurality of units become almost the same, and so-called dumpling operation may occur. Therefore, the elevator system as a whole has a problem that it is difficult to obtain sufficient operation efficiency as compared with the immediate forecast method.

  Therefore, when a hall call occurs on a specific floor where the floor indicator 70 indicating the current positions of a plurality of units is arranged, the control unit 11 of the elevator group management control device 10 according to the present embodiment calls the hall call. When the hall call is generated on a floor other than the specific floor, the group management control of the instant forecast method is executed for the hall call.

  According to such control, when a hall call occurs on the specific floor where the floor indicator 70 is arranged, the car having the minimum response time is assigned. Therefore, there is a high possibility that a car existing near the specific floor will be assigned. Therefore, the user waiting while watching the floor indicator 70 on the specific floor is prevented from feeling uncomfortable.

  On the other hand, when a hall call occurs on a floor other than a specific floor, an evaluation value regarding the allocation suitability of each unit for the hall call is obtained based on multiple parameters indicating the operating status of each unit, and multiple units are The hall call is assigned to the car having the evaluation value showing the highest suitability for assignment. Therefore, the operating efficiency of the elevator system as a whole can be appropriately secured.

  As described above, according to the present invention, it is possible to appropriately secure the operation efficiency of the entire elevator system while suppressing the discomfort of the user on the specific floor.

(Embodiment 2)
In the first embodiment, the simplified method is always applied on the specific floor. On the other hand, in the present embodiment, the simplified method is applied only to the time period other than the predetermined congestion time zone on the specific floor, and the immediate forecast method is applied to the predetermined floor time. Hereinafter, the configuration and the like for that will be described focusing on the differences from the first embodiment.

  In the present embodiment, a hall lantern 80 is arranged on the specific floor together with the floor indicator 70. This is because the guidance of the car is provided by the immediate forecast method.

  FIG. 8 is a flowchart illustrating a number assignment process for a hall call by the group management control device 10 according to the second embodiment. In this embodiment, the process of step S112 is additionally performed. Note that the same step numbers are assigned to the steps that execute the same processing as that of the first embodiment.

  When the floor for which the hall call is registered is the specific floor in step S12 of FIG. 8 (YES in S12), the control unit 11 of the group management control device 10 determines whether or not the current time is in a predetermined congestion time zone. (S112). The predetermined congestion time zone is, for example, a work time zone from 8:00 am to 9:00 am and a lunch time zone from 12:00 to 13:00.

  Then, when the current time is not within the predetermined congestion time zone (NO in S112), the control unit 11 of the group management control device 10 assigns the hall call to any one of the plurality of units by a simple method (S13). .. Then, the control unit 11 of the group management control device 10 outputs a lighting control signal to the hall lantern 80 corresponding to the assigned car on the specific floor immediately before the assigned car arrives at the specific floor, and turns on the hall lantern 80.
