BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator monitoring and control device, and more particularly to an elevator monitoring and control device that monitors and controls the operation of a plurality of elevators based on allowable electric energy. .

2. Description of the Related Art As a conventional elevator monitoring and control system of this type, there is a technique disclosed in Japanese Patent Application Laid-Open No. 57-90368.

[0003] Normally, the power consumption from when an elevator starts running until it stops is rapidly consumed during acceleration, and a peak occurs, and the power consumption during steady running is considerably smaller than during acceleration. Factors that influence this power consumption include the number of passengers in the car, driving direction, travel distance, and travel speed.

[0004] Therefore, by controlling the start timing of the elevators, simultaneous acceleration of a plurality of elevators can be avoided, operation control can be performed to suppress peak power consumption, and power saving can be promoted.

[0005] Therefore, in the conventional elevator monitoring and control device disclosed in the above publication, the power consumption required for operation of the elevator is predicted and calculated, and the predicted value of the power consumption is compared with a predetermined allowable value, and the predicted value is calculated. When it is detected that the permissible value has been exceeded, at least one elevator is controlled to an operating state different from the predicted operating state, and the number of elevators that can be activated simultaneously is controlled for each group management control means. .

[0006]

SUMMARY OF THE INVENTION In the conventional elevator monitoring and control apparatus as described above, the permissible value of power consumption of the elevator is fixed for each group management control means.

Therefore, even if all the elevators controlled by one group management control means are stopped and there is surplus power, the number of elevators that can be started within this group management control means is limited. The power could not be allocated to other group management control means, and the power could not be used effectively. As a result, the elevators could not be operated efficiently.

[0008] Therefore, the present invention provides an elevator monitoring and control device that can appropriately allocate and set the number of elevators to be activated to each group management control means according to the permissible value of power consumption of the elevator and the operation status of the elevators. The challenge is to provide this information.

[0009]

[Means for Solving the Problems] The present invention provides group management control means for group management of a plurality of elevators, and supervisory control means for monitoring and controlling the operation of each of the elevators via the plurality of group management and control means. and allowable power amount detection means for detecting the allowable amount of power that can be consumed by each of the elevators, and startable number setting means that determines the number of elevators that can be started simultaneously in the entire building based on the allowable power amount. and a start-up permitted number setting means for allocating the startable number of elevators to each group management control means according to the operation status of each elevator and setting the start-up permitted number.

0010

[Operation] In the elevator monitoring and control device of the present invention, the allowable power amount that can be consumed by each elevator is detected by the allowable power amount detection means, and based on this allowable power amount, the elevators can be started simultaneously in the entire building. The number of elevators that can be started is determined by the number of elevators that can be started, and the number of elevators that can be started is allocated to each group management control means that manages a plurality of elevators in a group according to the operation status of each elevator, and the number of elevators that can be started is allocated to each group management control means that manages a plurality of elevators in groups. Since the number of units that can be activated can be efficiently distributed to the group management control means,
Peak power consumption can be suppressed.

[0011]

[Examples] Examples of the present invention will be described below.

FIG. 1 is a block diagram showing an elevator monitoring and control device according to an embodiment of the present invention.

In the figure, reference numeral 1 denotes a group management control means for group management of a plurality of elevators, 2 an operation status detection means for detecting the operation status of each elevator controlled by the plurality of group management control means 1, and 3 a building. An external device that detects the overall power consumption situation, 4 is an allowable power amount detection means that detects the allowable power of the elevator, and 5 is a simultaneous activation of the entire building based on the allowable power amount detected by the allowable power amount detection means 4. 6 is a startable number setting means for setting the number of elevators that can be activated, and 6 is a means for setting the number of elevators that can be started. This is a startup-permitted number setting means for setting the number of startup-permitted devices of the management control means 1.

Next, the specific structure of the elevator monitoring and control device of this embodiment will be explained. FIG. 2 is an overall configuration diagram showing a specific configuration of an elevator monitoring and control device according to an embodiment of the present invention.

In the figure, reference numeral 7 denotes a controller for each elevator, which is connected to the group management control means 1. 1a is a CPU functioning as a central processing unit of the group management control means 1; 1b is an I/F for connection with each unit controller 7;
c is a memory in which programs and data are stored, 1
d is an I/F for connection with a monitoring control means 8, which will be described later. An elevator operation control command signal from the supervisory control means 8 is serially communicated via this I/F 1d. Reference numeral 8 denotes a supervisory control means for transmitting various operation control commands to each group management control means 1 to monitor and control the operation of the elevators, and similarly to the group management control means 1, it is equipped with a CPU 8a and a memory 8c. , an I/F 8b for connection with each group management control means 1, and an I/F 8d for connection with the allowable power amount detection means 4.

In the elevator monitoring and control device having the above structure, the number of elevators permitted to start is set for each group management control means 1. FIG. 3 is a flowchart showing a program for setting the number of elevators permitted to start for each group management control means of an elevator monitoring and control device according to an embodiment of the present invention.

In the figure, in step S1, the quotient of the allowable power amount and the power consumption required to start one elevator is determined as the number of startable elevators. Note that the allowable power amount is determined by the allowable power amount detection means 4.
It is determined by In step S2, step S1
The number of elevators that can be started is compared with the number of elevators that are activated, and if the former (the number of elevators that can be started) is greater or equal, the operation to set the number of elevators that are allowed to start is completed, and the number of elevators that can be started is If the number of machines) is smaller, step S3
Then, the number of groups to be managed by the group management control means 1 connected to the elevator supervisory control means 8 is set. Next, in step S4, it is determined whether or not the number of devices that can be activated is 0. If the number of devices that can be activated is 0, the operation of setting the number of devices that are allowed to start is completed. If the number of elevators that can be activated is not 0, the number of elevators that are allowed to start is compared with the number of elevators that are activated within the group management in step S5, and if they are equal, the process proceeds to step S8; if they are not equal, the number of elevators that are allowed to start is determined in step S6. Add 1 to
In step S7, 1 is subtracted from the number of devices that can be started, and one of the number of devices that can be started is assigned as the number of devices that are allowed to start. Then, in step S8, 1 is subtracted from the group management number of the group management control means 1, and the process proceeds to the next group management, and the processing from step S4 is performed. This operation is continued until the number of groups managed by the group management control means 1 becomes zero. Then, in step S9, when the number of groups managed by the group management control means 1 becomes 0 and the processing for all group management is completed, the process from step S3 is repeated again, and the number of devices that can be activated becomes 0. The above-mentioned series of operations for setting the number of devices to be activated is completed.

As described above, the elevator monitoring and control device of this embodiment includes a group management control means 1 for group management of a plurality of elevators, and a group management control means 1 for monitoring the operation of each elevator. a supervisory control means 8 for controlling the above-mentioned elevators; an allowable power amount detection means 4 for detecting the allowable amount of power that can be consumed by each elevator; a number setting means 5 for determining the number of elevators that can be started; and a group management control means 1 for determining the number of elevators that can be started according to the operation status of each elevator.
and a startup permission number setting means 6 for setting the number of startup permission devices to be allocated. Note that the bootable number setting means 5 and the bootable number setting means 6 are executed within the monitoring control means 8, and specifically, are executed according to the program flowchart of FIG. 3.

That is, in the elevator monitoring and control device of this embodiment, the allowable power amount detecting means 4 detects the allowable amount of power that can be consumed by each elevator, and based on this allowable amount of power, the entire building can be activated simultaneously. Each group management control means 1 determines the number of elevators that can be started by a startable number setting means 5, and manages a plurality of elevators in groups by means of a starting permitted number setting means 6, which determines the number of elevators that can be started according to the operation status of each elevator. This is to set the number of devices that are allowed to be activated.

Therefore, in this embodiment, the permissible power consumption value of the elevator is not fixed for each group management control means 1, but all the elevators controlled by a certain group management control means 1 are stopped and the power consumption is reduced. If there is a margin, the number of elevators that can be started within this group management control means 1 can be allocated to other group management control means 1. Therefore, it is possible to appropriately allocate and set the number of elevators that are permitted to start up to each group management control means 1 according to the permissible value of power consumption of the elevators and the operation status of the elevators, thereby efficiently controlling the number of elevators that can be started up. Since the power can be distributed to means 1, the peak power consumption can be suppressed, the allowable power of the elevators in the entire building can be used effectively, and the elevators can be operated efficiently.

By the way, in the above embodiment, the case where the number of units that can be activated is equally allocated to each group management control means 1 has been explained, but it is possible to increase the number of units that can be activated to a certain group management control means 1, or , priorities may be assigned according to the group management control means 1.

[0022]

As explained above, the elevator supervisory control device of the present invention includes a group management control means, a supervisory control means, a startable number setting means, a startable number setting means, and a control device for each elevator. The allowable power amount that can be consumed in the building is detected by the allowable power amount detection means, and based on this allowable power amount, the number of elevators that can be started simultaneously in the entire building is determined by the startable number setting means. The number of elevators that can be started can be set efficiently by setting the number of elevators that can be started by allocating the number of elevators to each group management control means that manages multiple elevators in a group using the startup-permitted number setting means according to the operation status of each elevator. Since the power can be distributed to the management control means and the peak power consumption can be suppressed, the allowable power of the elevators in the entire building can be used effectively, and the elevators can be operated efficiently.
