The allocation control switching unit 607 is registered on the floor that is determined to correspond to the peak time zone when the landing call registration method is switched to the registration method by the vertical call by the landing call registration method switching unit 605. Regarding the call, an instruction to switch to the multiple-unit allocation control that allocates a plurality of elevators to one call is output to the vertical call allocation control unit 602b.

<Operation of the elevator system using the group management control device according to the first embodiment>
Next, the operation of the elevator system 1 according to the present embodiment will be described with reference to the flowchart of FIG. FIG. 3 shows a flow of determination processing of response control contents for a landing call on each floor, which is executed at a predetermined timing in the group management control device 61 while the elevator system 1 is in operation.

In the present embodiment, the landing destination floor call assignment control unit 602a sends the landing call reception / registration unit 601 to the landing destination floor call reception / registration unit 601 for the floor where the landing call registration method is switched to the landing destination floor call as the normal landing destination floor call allocation control. It is set to determine the optimum one assigned machine for one registered landing call. Further, the upper / lower call assignment control unit 602b previously performs the upper / lower call allocation control at the normal time for one landing call registered in the landing call reception / registration unit 601 for the floor where the landing call registration method is switched to the upper / lower call. , It is set to determine the most suitable one assigned machine.

First, the floor registration method determination unit 606 of the group management control device 61 selects a floor to be processed, for example, "1st floor", and the "1st floor" is the vertical call registration device and the landing destination floor call registration device. It is determined whether or not the floor is annexed (S1). Here, since these devices are installed side by side on the “1st floor” (“YES” in S1), the process proceeds to step S2.

The floor registration method determination unit 606 further determines whether or not the current landing call registration method of the "1st floor" is the landing destination floor call registration method based on the switching command output from the landing call registration method switching unit 605. Is determined (S2).

When the floor registration method determination unit 606 determines that the current landing call registration method for the "1st floor" is the landing destination floor call registration method ("YES" in S2), the allocation control switching unit 607 is set to "1. Regarding the "floor", the landing destination floor call allocation control unit 602a determines that the normal landing destination floor call allocation control is continued (S3).

Further, when the floor registration method determination unit 606 determines in step S2 that the current landing call registration method on the “1st floor” is the vertical call registration method (“NO” in S2), the allocation control switching unit 607 , It is confirmed by the peak time zone determination unit 604 whether or not the "first floor" is currently determined to be the peak time zone (S4).

Here, when it is not currently determined that the "1st floor" is not in the peak time zone ("NO" in S4), the allocation control switching unit 607 is a vertical call allocation control unit 602b for the "1st floor" and is usually used. It is determined that the up / down call allocation control of is continued (S5).

Further, when it is determined in step S4 that the "first floor" is currently in the peak time zone ("YES" in S4), the allocation control switching unit 607 responds to the vertical call allocation control unit 602b with "1". An instruction to switch to the multiple unit allocation control for "floor" is output (S6).

In step S1, when the floor to be processed is a floor on which the vertical call registration device and the landing destination floor call registration device are not installed (“NO” in S1, response control to the landing call after step S2). The content judgment process is not executed.

The group management control device 61 executes the above-mentioned processes of steps S1 to S6 for all floors in the building. Then, the vertical call allocation control unit 602b forcibly determines a plurality of allocation units for one landing call for the floor that has acquired the instruction to switch to the allocation control for a plurality of units from the allocation control switching unit 607.

Then, the allocation command output unit 603 is based on the allocation unit information determined by the landing destination floor call allocation control unit 602a or the allocation unit information determined by the vertical call allocation control unit 602b, and the control device 12A to the corresponding elevator. Output the allocation command to 12C.

In the elevator control devices 12A to 12C that have acquired the allocation command, the allocation response control units 122A to 122C assign the corresponding elevators 10A to 10C by the allocation command from the allocation command output unit 603 to the landing destination floor call or the registration floor of the vertical call. Respond to and open the door.

In the above first embodiment, when the landing call registration method is a landing destination floor call, the registered landing call is compulsory even during peak hours when high demand for the corresponding floor is expected. If the landing call registration method is up / down call without executing the multiple vehicle allocation process, forced multiple vehicle allocation is performed for the landing call registered on the floor during peak hours. By controlling in this way, when the landing call registration method is the landing destination floor call method, it is possible to prevent unnecessary response from being generated and the transportation efficiency is lowered, and in the case of the vertical call registration method, it is left unloaded. Can be prevented from increasing the waiting time of the user.
