DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator control device, and more particularly, to a system for inspecting an elevator on a car for inspection so that the elevator to be inspected can be immediately stopped at a position where the elevator can be loaded on the car. The present invention relates to an elevator control device.

[0002]

2. Description of the Related Art Elevators installed in high-rise buildings are operated under group management control. Recently, not only high-rise buildings but also middle-to-low-rise buildings have been equipped with a large number of elevators employing group management control. I have.

In a bank elevator having a group management control function, an arbitrary hall call is common to all elevators, and which is the most suitable for the hall call is calculated. An instruction is given to assign the most suitable machine to respond.

[0004] In such an elevator, a special car is used for regular inspection, inspection and repair work when a failure or the like occurs, but in a high-rise building, the elevator machine to be inspected is installed. It often takes time to catch. In order to stop the elevator of a specific car at the position where it was on the car, it had to make a hall call and wait for the elevator.

[0005]

Often times, during repeated hall calls a number of times, the elevator that was sent first instead of the intended elevator may come. In this way, it is difficult to catch the unit to be inspected, and while the target elevator does not come, it takes time to raise and lower the elevators unrelated to inspection many times, and in between that, wasted power energy Was spent. On the other hand, if the elevator to be inspected does not come after the hall call has been repeated several times, the elevators that responded temporarily are disconnected from the group management control, stopped as outside the group, and stopped one by one. It has been pointed out that there is a need for more troublesome procedure operations, such as reducing and catching from management control. Therefore, an object of the present invention is to solve the above-mentioned problems of the prior art, and when trying to check the elevator while riding on the car, the simple operation of operating the on-car check switch allows the elevator to be mounted on the car. It is an object of the present invention to provide an elevator control device in which an elevator is moved straight to a riding position.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to a group management operation device for sharing a hall call among a plurality of elevators and allocating an optimum elevator based on the hall call signal. A changeover switch for switching the control mode from the group management operation so that each elevator does not respond to a new hall call; controlling the operation of each elevator according to a command given from the group management operation device, Based on the ON signal from the switch, the subsequent assignment of the hall call to the corresponding elevator is prohibited, and if there is already a car call given to the corresponding elevator before the changeover switch is switched, the operation in response to this is completed. Operation control device that makes the elevator go straight to a predetermined position where the inspector gets in after It is a feature.

[0007]

According to the present invention, when inspecting an elevator, by operating the changeover switch, a hall call is not assigned, and the elevator operation control can be immediately started on the car from the group management operation. Is switched to the control to make the elevator go straight to the elevator. When the change-over switch is turned on, the corresponding elevator responds after the car call that has already been made disappears. Also, at the stop position of the last car call, the auto-announcer broadcasted, "We will check it now, so please use another elevator." The elevator may be made to go straight to the stop position.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a schematic diagram showing an elevator shaft controlled and controlled by a group and a car used for inspection and repair. In the figure, 1 indicates a hold door and 2 indicates a car. The car 2 is suspended by a wire cable 3 so that the hoistway 4 can be placed side by side at a position parallel to an elevator (not shown). In this embodiment, when the inspection worker inspects the elevator while riding on the ceiling 2a of the car 2, first, the ceiling portion of the elevator (not shown) to be inspected matches the level of the floor 5 on the top floor. As described above, after the elevator is stopped, the key of the hold door 1 is released and opened, and the rider gets on the car 2 via the elevator.

Next, FIG. 2 is a block diagram of a control system for performing group management operation control of the bank elevators from the a-th car to the n-th car. Reference numeral 6 denotes a hall call signal from each floor of the building. The hall call signal 6 is input to the group control operation device 7, and the group control operation device 7 controls the operation of each elevator car corresponding to a command signal for calculating and assigning the optimum car to the floor where the hall call was made. Devices 8a, 8
, 8n. In this embodiment, a group management operation control device 7 and an operation control device 8a of each elevator car,
, 8n are connected via out-of-group contacts 9a, 9b, ..., 9n. These external contacts 9a, 9b,...
9n is a contact for removing an elevator of an arbitrary group as required. Each group contact 9a, 9b, ..., 9n
Is a normally closed contact, and when group management operation control cannot be performed due to a failure, inspection, or the like, the contact can be opened to disconnect the elevator of a specific car from the control target.

Here, each of elevators a, b,
.., N operation control switches 10a, 1
.., 10n are provided. When the operation changeover switches 10a, 10b,..., 10n are set to ON, the operation control devices 8a, 8b,.
The car call from the group management operation device 7 is not assigned to n, and the operation control devices 8a, 8b,.
In accordance with the processing content of the flowchart of FIG. 3, the elevators a, b,..., N are deviated from the group management operation control, and are shifted to operation control for repairing and inspecting the elevator. On the other hand, the operation changeover switch 10a,
When 10b,..., 10n are set to OFF, normal group management operation control for controlling the operation of each elevator a, b,. I have.

FIG. 3 is a flow chart showing the elevator operation control when the elevator is inspected while riding on the car 2. The operation of the present embodiment will be described below with reference to this flowchart. I do. First, if the elevator to be inspected is, for example, the elevator a among the elevators a to n, the changeover switch 10 of the elevator a
When a is turned on, the following processing is started. In step S1, even if there is a hall call, the group management operating device 7 prohibits the assignment of the hall call to the car No. a to be inspected, which is to be inspected, and allocates the hall call to another car other than the car a. If there is a car call before the changeover switch 10a is turned on, YES in step S2.
The control of step S3 for responding to the car call already made is executed for the car a to be inspected. This process
The process is performed until there is no more car call made before the changeover switch 10a is turned on. If there is no more car call (No in step S2), the processing contents from step S4 are performed.

In step S4, in response to the final car call, in order to prevent the passenger from getting in at the position where the car No. a is stopped, and when a passenger who does not know that the inspection is to be started comes in, In order to call attention, a guidance broadcast about the start of the inspection work, for example, "A new elevator will be inspected now, so please use another elevator."

Next, in step S5, the illumination lamp in the elevator is turned off, and after a while, the door is closed. In this way, after taking all possible measures to prevent anyone other than those concerned from getting on elevator a, which has been removed from normal group management operation for inspection, proceed to step S6, where car 2 An operation signal for causing the elevator a to go straight to the position where the user rides on the vehicle is supplied to the operation control device 8a. Elevator a, upon receiving a command from the operation control device 8a, stops as shown in FIG. 1 such that the ceiling portion matches the level of the floor 5 on the top floor. At this time, the key of Holder 1 has been released, and the worker
Can be opened and the user can get on the ceiling of the car 2 via the ceiling of the elevator.

As described above, according to the present embodiment, the changeover switches 10a, 10a corresponding to the elevator to be inspected.
With the simple operation of inserting 0b,..., 10n, the hall call switches from the common group management operation control to the control for elevator inspection. You can go straight to the position you need to ride.

As described above, the switches 10a, 10b,.
Although the embodiment in which n is attached to the control panel of the machine room has been described, the present invention is not limited to this embodiment.
For example, by adding a contact to a parking switch installed in a hall, the same function can be obtained by operating from the hall. Also, as for the method of transmitting and receiving the operation switching signal by the changeover switch, it is also possible to adopt a wireless method or a method such as encryption registration using a button on the operation panel.

[0016]

As is apparent from the above description, according to the present invention, when performing an inspection and repair of an elevator controlled in the county operation, the target elevator is operated by operating the changeover switch once. The system is configured so that it can be stopped immediately at a position where it can be put on the car, so that the time required for inspection can be shortened, efficient inspection and repair work can be performed, and service to users can be improved. Energy waste can be eliminated.
