Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the configuration of an elevator group supervisory control device according to the first embodiment of the present invention. In the figure, the group management control device 8 controls the entire elevators 15 with cooling devices having the cooling device 2 on the cab 1 via the elevator control devices 7 as a whole.
Each car room 1 of each elevator 15 with a cooling device is connected to a cooling device 2 via a drain hose 3, a tank 4 for storing drainage from the cooling device 2, and a water level detecting device 5 for detecting the water level of the tank 4. , And a drainage device 12 attached to the lower side of the tank 4 for draining the water accumulated in the tank 4. A drainage port 13 is provided on the lowest floor of the hoistway of each elevator so that water from the tank 4 can be drained through the drainage device 12 of each elevator.

The water discharged from the cooling device 2 mounted for cooling the cab 1 is stored in the tank 4 via the drain hose 3, and the water level in the tank 4 is detected when the water in the tank 4 is full. When detected by the device 5, the water level detection device 5 outputs a full water signal 6 to the corresponding elevator control device 7. The elevator control device 7 outputs a drainage request 9 to the group management control device 8 in response to this full water signal.

Upon receiving this drainage request 9, the group management control device 8 outputs a drainage command 10 to the corresponding elevator control device 7 when the drainage condition is satisfied, as will be described later. Upon receiving this drainage command 10, the elevator control device 7 directs the corresponding elevator 15 to the lowermost floor, stops at the lowest floor, and then outputs the drainage signal 11 to the drainage device 12. The drainage device 12 responds to the drainage signal 11 to pass the water in the tank 4 through the drainage device 12 to the drainage port 13 of the hoistway.
Drain to.

Further, the elevator control unit 7 uses the full water signal 6
Regardless of whether or not there is a drainage command from the group management control device 1
With 0, the corresponding elevator 15 can be directed to the lowest floor for drainage.

Next, the operation of the first embodiment will be described with reference to the flow chart shown in FIG. In FIG. 2, first, the group management control device 8 determines whether or not there is a drainage request 9 from the elevator control device 7 (step 10).
1). If there is a drainage request 9, it is determined whether or not another elevator is heading for drainage or is being drained (step 102). If it is heading for drainage or if there is something in drainage, it waits until drainage of the elevator is completed (step 104), and proceeds to step 103. If there is no other elevator in the drainage, the process immediately proceeds to step 103.
In step 103, it is determined whether or not there is only one drainage request 9, and if there is only one drainage command 9, a drainage command 10 is output to the elevator that has issued the drainage request 9 (step 10
5) Allow drainage.

If it is determined in step 103 that the number of drainage requests 9 is not one, the drainage command 10 is output to the elevator having the smallest machine number among the elevators that issued the drainage request 9 to drain the water. Then, the drainages of the plurality of elevators are controlled so as not to overlap (step 106). For the other elevators for which the drainage command has not been issued, return to step 102, wait until the drainage of the elevator for which the drainage command has been issued is completed in step 106 (step 104), and repeat the processing from step 103 onward. By doing this, control is performed so that the water is discharged one by one.

As described above, even if a plurality of drainage requests 9 are made, it is possible to prevent the reduction of the transportation power by controlling the drainage by one unit at a time. Next, FIG.
The operation of the second embodiment of the present invention will be described with reference to the flowchart shown in FIG. The configuration of the second embodiment is the same as that shown in FIG. 1, except that the group management control device 8 incorporates the processing shown in FIG.

In FIG. 3, first, the group management control device 8
Is a determination as to whether it is within a certain time before driving at work (step 201), a determination as to whether it is within a certain time before driving at lunch (step 202), and before driving at work. Whether it is within a certain period of time (Step 2
03) is performed, and if either is the case, the drainage command 10 is first issued to the elevator with the smallest machine number in order to drain all the elevators in advance (step 204). Then, it waits until the drainage of this elevator is completed (step 205), and then issues the drainage command 10 to the elevator with the smallest machine number (step 206).
It is determined whether or not the drainage of all the elevators is completed (step 207), and if it is not completed, the step 205 is performed until the drainage processing of all the elevators is completed.
Repeat the above.

As described above, transportation capacity is needed by draining all the elevators one by one before the time when transportation capacity is required, such as when going to work, at lunch, when leaving work, etc. It is possible to prevent the drainage from being performed during the period. The time zone that requires transportation capacity is not limited to the time of going to work, lunch, and leaving, and it is possible to set a time zone specific to the building.

Next, the operation of the third embodiment of the present invention will be described with reference to the flow chart shown in FIG. The configuration of the third embodiment is the same as that shown in FIG. 1, except that the group management control device 8 incorporates the processing shown in FIG.

In FIG. 4, first, the group management control device 8
Determines whether there is a drainage request 9 (step 30).
1). When there is a drainage request 9, the interval of the drainage request 9 is calculated from the time of the previous drainage request 9 and the current time of the machine that issued this drainage request 9 (n-th machine), and as T (n) It is stored (step 302). Further, the current latest time when the drainage request 9 is made is stored as t (n) (step 303).

Then, the drainage command 10 is issued to the machine having the drainage request 9 (step 304). At this time, if there are drainage requests 9 from a plurality of elevators, the drainage commands 10 are issued one by one in order from the smallest machine number as in the first embodiment, and the water is drained.

If there is no drainage request 9 in the judgment of step 301, it is judged whether or not it is within a certain time period before the driving at work, the driving at lunch, or the driving at work (step 305). . If it is within a certain time, the time of the next drainage request of all elevators is t (n) + T
It is predicted as (n) (step 306), and it is determined whether or not this predicted time overlaps the time zone of driving at work, driving at lunch, or driving at work (step 307). If there are overlapping ones, a drainage command is issued one by one in order from the smallest numbered machine number to cause drainage (step 308). Further, the time t (n) at which the latest drainage request of the machine that issued the drainage command 10 is made is updated to the current time (step 309).

As described above, when the interval of the drainage request is stored for each unit and the drainage is expected during the time when the transportation capacity is required, such as when going to work, at lunch, and when leaving the office. Only by performing drainage in advance, it is possible to prevent drainage during a time period when transportation capacity is required.

Next, the operation of the fourth embodiment of the present invention will be described with reference to the flow chart shown in FIG. The configuration of the fourth embodiment is the same as that shown in FIG. 1, except that the group management control device 8 incorporates the processing shown in FIG.

In FIG. 5, first, the group management control device 8
Determines whether there is a drainage request 9 (step 40
1). If there is a drainage request 9, it is determined whether or not a downward landing call is registered between the floor that can stop at the current floor of the unit that issued the drainage request 9 or if it is running, the lowest floor. (Step 402). If it is not registered, the process jumps to step 405 to issue the drainage command 10 to the unit that has the drainage request 9 to cause it to drain, but if there is a registered landing call, then that landing call is issued to the drainage request 9.
After the completion of the call (step 404), the machine having the drainage request 9 issues the drainage command 10 to drain the water (step 405).

In the above processing, the operation time for drainage can be shortened by issuing the drainage command 10 for draining after moving the unit for which the drainage request 9 is made as downward as possible.

[0031]

As described above, according to the present invention,
When there are multiple drainage requests from an elevator, a drainage command is issued to only one of the elevators, and the elevator that receives the drainage command completes drainage before issuing a drainage command to the next elevator. Since the drainage of water is controlled so that it does not overlap, it is possible to prevent a reduction in transportation capacity.

Further, according to the present invention, at work, at lunch,
Regardless of whether there is a drainage request before the time when the transport capacity of the elevator is required, including when leaving the office, issue a drainage command to all elevators one by one, and before the time when the transport capacity is required, all The elevator will be drained and controlled so that it will not drain during the time when transportation is required.
It is possible to prevent drainage from being performed during a time period when transportation capacity is required.

Further, according to the present invention, the time interval of the drainage request is measured, the time when the next drainage request is issued is predicted from this time interval, and the estimated time includes the time of going to work, lunch, and leaving the elevator. Detecting an elevator that overlaps with the time zone that requires transportation capacity, issue a drainage command to the elevator a predetermined time before the time when transportation capacity is required, and do not drain in the time zone that requires transportation capacity. Therefore, it is possible to prevent the drainage from being performed during the time period when the transportation capacity is required.

Furthermore, according to the present invention, a downward hall call existing below the current position of the elevator that has received the drainage request is detected, and the hall call is given priority to the elevator that has received the drainage request. The elevator is moved downward in response to this landing call, and a drainage command is issued to the elevator to control the drainage operation time so that the drainage operation time is shortened. Can be shortened.
