DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing the configuration of a group management control system of the present invention.

In FIG. 1, a group management control system manages each elevator as a group, performs group call allocation control and operation mode switching control, and a group management control apparatus 1 and an operation mode provided in the group management control apparatus 1. A group pipe control unit 2 that performs switching control and the like, an assignment control unit 3 that is provided in the group management control device 1 and that inputs hall call information and the like from each floor and allocates and controls an optimal elevator, and is provided in each floor hall Hall call buttons 4a to 4n for registering hall calls, hall call input / output control units 5a to 5n for controlling input / output of hall calls from the hall call buttons 4a to 4n, and call response control provided for each elevator. And elevator control devices 6a to 6n for controlling door opening and closing, and elevator control devices 6a to 6n
Each of the cars 7a to 7n is used to service passengers.

Explaining the operation of the above-mentioned structure, first, when the passenger pushes the hall call buttons 4a to 4n, the microcomputers of the group management control unit 2 and the allocation control unit 3 in the group management control unit 1 perform logic.・ Calculate, select and determine the most suitable elevator, and service the elevator. The hall call registered with the hall call buttons 4a to 4n is sent to the allocation control unit 3 in the group management control device 1 by the hall call input / output control units 5a to 5n.

Within the allocation control section 3, the hall call registration state is monitored using a hall call information table (hereinafter referred to as HCT) as shown in FIG. This HCT is set so as to be able to store information for each ascending hall call and descending hall call on each floor. For example, if a down hall call on the second floor occurs, HC
The Ba bit of 2d of T is set, and when the allocation control unit 3 selects and allocates the optimum machine, the HCT allocation bit Bb is set. When the assigned elevator has finished responding to the down hall call on the second floor, the call bit Ba and the assignment bit Bb of the HCT are cleared.

Therefore, the operation of the group supervisory control device of the present invention at the time of switching from the working mode at work to the normal operation mode or at the time of switching from the normal operation mode to the working mode at work is shown in FIG. This will be described using a flowchart.

First, the group management control unit 2 determines whether it is the time zone of the operation mode at work (step 1), and when it is determined that it is the time zone of the operation mode at the time of work, the car loading load on the standard floor is determined. Specified value (45% of the car's rated load)
(Step 2).
When it is determined in step 2 that the predetermined value has been reached, the mode is switched to the operation mode at work (step 3). Here, it is again determined whether or not it is the time zone of the operation mode at work (step 4), and it is determined at step 4 that it is the time zone of the operation mode at time of work, and when it is switched to the operation mode at the time of work, the allocation control unit 3 The ratio of the total number of descending hall calls to the total number of hall calls is calculated by the group management control unit 2 based on the information of the HCT call bit 3a in the group management control unit 2. RO preset
It is compared with a predetermined ratio (about 35% to 40%) stored in M (step 5). As a result of the comparison in step 4, when the calculated current ratio has reached the predetermined ratio, the group management control unit 2 counts the elapsed time, and R
It is judged whether or not the current ratio has reached a predetermined ratio continuously for a predetermined time stored in the OM (step 6). If it is judged that the current ratio has reached the predetermined time or more, the normal operation is performed. The mode is switched (step 7). If it is determined in step 1 or step 4 that it is not the time zone of the attending operation mode, the process proceeds to step 7 to enter the normal operation mode. If it is determined in step 2 that the car loading load at the standard floor has not reached the predetermined value, the process proceeds to step 1 and the above-described operation is performed. Further, if it is determined in step 5 or step 6 that the ratio has not reached the predetermined value or has exceeded the predetermined value for the predetermined time or more, the process proceeds to step 3 and the above-described operation is performed.

As described above, according to the present embodiment, the ratio of the total number of descending hall calls to the total number of hall calls becomes a predetermined value or more even during the time zone of the operation mode when commuting to work, and this state continues for a predetermined time or more. In this case, it is possible to switch to the normal operation mode, so it is not necessary to wastefully drive in the operation mode when attending work while the passengers getting on and off the service on the standard floor are completed. It becomes possible to control.

In the present embodiment, the ratio of the total number of descending hall calls to the total number of hall calls is calculated, but the ratio of the total number of ascending hall calls to the total number of hall calls is calculated in the same manner. Needless to say, the effect of can be obtained.
