  However, if the control as described above is performed, it is avoided that the user misses the car for the time required for the user to move to the assigned car platform in order to keep the car open. However, since the car is restrained and does not respond to other calls while the door is open, there is a problem in that the transportation efficiency decreases during that time.

  The present invention has been made in view of the above circumstances, and when performing group management of a plurality of elevators installed in a building based on the user's destination floor information detected at the elevator landing floor, It is an object of the present invention to provide an elevator group management control device and a group management control method that suppress a decrease in transportation efficiency while providing high convenience.

  According to the embodiment for achieving the above object, the group management control device includes a user travel time determination unit, an allocation priority determination unit, a predicted car arrival time calculation unit, and an allocation car determination unit. The user travel time determination unit determines the time required for the user to travel from the landing destination floor call registration device to the elevator platform. The assignment priority order determination unit determines the priority order of the assigned cars when an elevator call is generated. The predicted car arrival time calculation unit calculates the time at which each elevator car arrives at the floor where the elevator call is generated. The assigned car determination unit determines, as the assigned car, the car having the highest priority of the assigned car among the cars that can secure time for the user to move to the landing before the arrival of the car.

<Operation of Elevator System Using Group Management Control Device According to First Embodiment>
Next, operation | movement of the elevator system 1 by this embodiment is demonstrated with reference to the sequence diagram of FIG.

  In the present embodiment, the user movement time setting unit 301 of the group management control device 30A requires that the user move in a planar manner from the landing destination floor call registration device 20 to the landings 12-1 to 12-3. It is assumed that the movement time is set as a fixed value as “30 seconds”.

  When any one of the buttons in the destination floor call button group 21 of the landing destination floor call registration device 20 is operated by the user in the state where the travel time is set in this way, the elevator call information generated by this operation Is registered in the call registration unit 22 (S1).

  Next, the elevator destination call information registered in the call registration unit 22 of the landing destination floor call registration device 20 is recognized in the landing destination floor call recognition unit 302 of the group management control device 30A (S2).

  Next, in the user travel time determination unit 303, the user moves to each of the landings 12-1 to 12-3 after the elevator call information is registered based on the information set by the user travel time setting unit 301. It is determined that the user travel time is “30 seconds” (S3).

  Next, in the allocation candidate car evaluation unit 304 and the predicted car arrival time calculation unit 305, operation status information (position information of each car 11-1 to 11-3, (Movement direction, destination registration status, etc.) are acquired (S4).

  Next, in the allocation candidate car evaluation unit 304, occurrence occurs based on the elevator call registration information recognized in step S2 and the latest operation status information of each of the elevators 10-1 to 10-3 acquired in step S4. The priority of assignment of the cars 11-1 to 11-3 for responding to the registered elevator call registration is determined (S5). Here, it is assumed that the car is determined to have a higher priority in the order of the car 11-1 → the car 11-2 → the car 11-3.

  Next, in the estimated car arrival time calculation unit 305, for the elevator call registration information recognized by the landing destination floor call recognition unit 302 based on the latest operation status information of each elevator 10-1 to 10-3, A predicted car arrival time, which is a time required for each of the cars 11-1 to 11-3 to arrive at the landing floor in response, is calculated (S6). Here, the estimated arrival time of the car 11-1 is calculated as “10 seconds”, the estimated arrival time of the car 11-2 is “25 seconds”, and the predicted arrival time of the car 11-3 is calculated as “35 seconds”. Shall be.

  Next, in the travel time comparison unit 306, the first user travel time determined by the user travel time determination unit 303 and the cars 11-1 to 11-3 calculated by the predicted car arrival time calculation unit 305. The estimated arrival time of the car is compared, and it is determined whether or not a sufficient time can be secured for the user to move to the corresponding landing by the arrival of each car (S7).

  Here, the first user travel time “30 seconds” determined by the user travel time determination unit 303 and the estimated car arrival time “10” of the car 11-1 calculated by the predicted car arrival time calculation unit 305. The time difference that is the comparison result with “second” is calculated as “−20 seconds”, the time difference that is the comparison result with the expected arrival time “25 seconds” of the car 11-2 is calculated as “−5 seconds”, The time difference which is a comparison result with the estimated car arrival time “35 seconds” of the car 11-3 is calculated as “+5 seconds”.

  Next, in the restricted car selection unit 307, as a restricted car, it is determined from the comparison result of the travel time comparing unit 306 that it is determined that the time for the user to move to the corresponding landing by the arrival of the car cannot be secured sufficiently. Selected (S8).

  In the present embodiment, a passenger car whose time difference calculated as a comparison result is smaller than “−10 seconds” is moved to the call generation floor in response to the elevator call. It may be left in response to another call that occurs before arrival, and it is determined that the user's travel time cannot be secured and is selected as a restricted car. Specifically, since the time difference “−20 seconds” calculated for the car 11-1 is smaller than “−10 seconds”, it is selected as a restricted car.

  Next, in the assigned car determination unit 308, among the cars that are not selected as the restricted car by the restricted car selection unit 307, the car having the highest assignment priority determined by the assignment candidate car evaluation unit 304 is the elevator. It is determined as an assigned car to respond to call registration (S9).

  In the present embodiment, the car 11-2 and the car 11-3 which are not selected as the restricted cars are the cars to be assigned, and the passengers are picked up based on the priority determined in step S5. The car 11-2 is determined as the assigned car.

  The determined assigned car information is transmitted to the assigned car notifying device 40 and output for notifying the user. The assigned car notification device 40 is constituted by, for example, a display device, a speaker, and the like, and is notified by display on the display device, sound output from the speaker, or the like.

  Further, when the car 11-2 is determined as the assigned car, this information is transmitted to the control device (not shown) of the corresponding elevator 10-2, and the car 11-2 responds to the elevator call registration. It is controlled to move to the landing floor (S11).

  According to the above embodiment, based on the call registration by the destination floor call registration device installed on the landing floor, the user can transfer a plurality of elevators installed in the building from the destination floor call registration device to the elevator landing. Since the group management control is performed while securing the traveling time, it is possible to perform the elevator operation control that suppresses a decrease in transportation efficiency while providing high convenience to the user. Accordingly, it is possible to prevent a situation in which a plurality of elevator calls are generated for a single user by registering the call again after being late in the car that has been moved in response to the call registered by the user.

  In the first embodiment, the user travel time setting unit 301 sets the travel time individually for each car, and the user travel time determination unit 303 and the travel time comparison unit 306 travel to the corresponding car. Information may be used.

  Furthermore, as shown in FIG. 4, a plurality of landing destination call registration devices 20-1 to 20-4 and assigned car notification devices 40-1 to 40-4 are installed on the landing floor, and the group management control device 30A is used. The passenger travel time setting unit 301 sets the travel time for each combination of the landing destination floor call registration devices 20-1 to 20-4 and the landings 12-1 to 12-3, thereby determining the user travel time. The travel time information related to the combination of the corresponding landing destination floor call registration device and the landing may be used in the part 303 and the travel time comparison part 306. At this time, the determined assigned car information is output to an assigned car notifying device installed in the vicinity of the corresponding landing destination floor registration device.
