Next, the operation of the platform destination floor display system 10 according to the first embodiment will be described.

FIG. 5 is a flow chart for allocating a car to a user based on the data of the input destination floor call. Next, allocation processing will be described with reference to FIG.

First, the elevator user presses or touches the desired floor button 14 on the input device 5 . Then, the destination floor call (hall call) is registered in the platform destination floor registration device 13 . Here, both the data of the destination floor and the data of the hall call to the departure floor are registered.

In step S101 of FIG. 5, it is determined whether or not all cars 6 are expected to be fully occupied at the departure floor.

In step S102 of FIG. 5, it is determined whether or not there is a car for which the same previously registered destination floor call as the newly registered destination floor call is not registered. exists (if YES), the process proceeds to step S103.

In step S103 of FIG. 5, the same elevator car as the new destination floor call is set to the destination floor of the registered destination floor call as a non-allocated elevator car, and the process proceeds to the next step S104 for allocation. The steps S102 and S103 are interposed between the steps S101 and S104 because the same destination floor is displayed on the destination floor display device 11 and the destination floor display device 12. This is to avoid With this configuration, it is possible to prevent the user from being confused as to which response car 6 should appear.

In step S101, if there is a car that is not expected to be full (NO), and if there is no car in which the same registered destination floor call as the new destination floor call is not registered in step S102 (NO), step S104 , and allocation processing is performed.

In step S104, based on the information of the new destination floor call input and registered from the input device 5 and the operation information of each car 6 input from the elevator group management control device 21, the number predicted to be the most appropriate is selected. assigned and registered. Here, the operation information of each car 6 input from each elevator control device 20 via the elevator group management control device 21 is information such as car position, driving direction, door open/close state, etc. Based on the destination floor call registration information etc. from the input device 5, select the most suitable car for allocating the hall call information from each car 6, assign the destination floor call to the most suitable car 6, The process proceeds to step S105. At this time, the assigned car number is displayed on the input device 5 . Therefore, the user can confirm the assigned car displayed on the input device 5, move to the boarding/alighting gate 3, and wait.

In step S105, it is determined whether or not the number of passengers in the assigned elevator is predicted to be less than full on the departure floor. The destination floor is displayed on the floor display device 11, and the allocation process ends.

In step S105, if the number of passengers in the assigned car is more than full at the departure floor (if NO), proceed to step S107, display the destination floor of the new destination floor call on the second destination floor display device 12, finish. Therefore, even if all elevators are expected to be full when a new destination floor call is entered and registered, the user who entered the new destination floor call will be assigned the most suitable elevator, and It is guided to 3. With this configuration, queues in front of the input device and congestion (stagnation) at the boarding point 1 can be avoided.

FIG. 6 is a flowchart of car response processing by the boarding point destination floor display system 10 according to the first embodiment. Here, the processing at the time of response of the assigned car 6 is shown. In FIG. 6, the left column shows the processing when the car 6 arrives at the departure floor, and the right column shows the processing when the car 6 departs.

In step S111 of FIG. 6, it is determined whether or not the response car 6 has arrived. If it is determined that it has arrived (YES), the process proceeds to step S112.

In step S112, the destination floor display device 11 of the arrival floor blinks, thereby informing the user of the platform 1 that the first responding car has arrived, and the process proceeds to step S113.

In step S113, since the car 6 has already arrived, the hall call assignment is deleted and the process proceeds to step S114.

Steps S114 to S119 are steps of loop processing of a destination floor call list, which is a list of registered destination floor calls. The process is repeated until the capacity of the car 6 is reached by picking up the cases one by one, and the loop process ends.

To explain the process of processing the destination floor call data of one user in the loop processing described above, in step S115, it is determined whether or not the floor where the elevator is stopped is the departure floor for the destination floor call. If so (if YES), go to step S116. Here, it is determined whether or not the number of passengers in the allocated car is less than full. If it is determined in step S116 that the car is less than full (if YES), the process proceeds to step S117 to delete the destination floor call data from the registered destination floor call list. That is, since the user has boarded the answering machine, it is deleted from the registered destination floor call list, and the process proceeds to the next step S118. In step S118, the car call for the destination floor is registered. That is, after the user gets in, a call is registered from the destination floor to call the car 6 to the destination floor. After the registration, the process returns to step S115 to process the destination floor call data of the next user.

In step S115, if the floor where the elevator is stopped is not the departure floor for the destination floor call (NO), and in step S116, if the number of passengers in the assigned car is more than full (NO), The process proceeds to step S119.

When the data processing for one destination floor call in the registered destination floor call list is completed, the process returns to step S115 again, and the loop processing from steps S115 to S118 is performed for the next user's destination floor call data. . The loop processing ends when the number of passengers in the car 6 reaches the capacity, and the process proceeds to step S121. Then, each process is performed at the departure timing of the elevator.

Next, the processing steps at the departure timing of the elevator in the right column will be described.

In step S121, it is determined whether or not the elevator has departed, and if it is determined that the elevator has departed frequently (in the case of YES), the process proceeds to step S122. In step S122, the display on the destination floor display device 11 and the destination floor display device 12 is erased, and the process proceeds to step S123. In step S122, all the displays on both the destination floor display device 11 and the destination floor display device 12 are erased.

In step S123, it is determined whether or not the data of the destination floor call for the departure floor of the departing elevator remains. If it is determined that the data remains (in the case of YES), the process proceeds to step S124 to assign the hall call to the departure floor. to register. Next, in step S125, the destination floors of the remaining destination floor call data are displayed on the destination floor display device 11 of the departure floor for the first time.

For example, as shown in FIG. 2, when "5 6 8 10" is displayed on the first destination floor display device 11 and "7 9" is displayed on the second destination floor display device 12, the first When the car 6 in response departs, the displays of "5 6 8 10" on the first floor display device 11 and the second floor display device 12 all disappear. After that, the destination floor "7 9" displayed on the second destination floor display device 12 is displayed on the first destination floor display device 11, and the next responding car stops at the 7th and 9th floors. is displayed. In other words, the content "7 9" displayed on the second destination floor display device 12 for the second time shifts to the first destination floor display device 11 for the first time.
