Abstract

PURPOSE:To permit the unmanned control operation by carrying out the automatic maintenance operation in an arbitrary number of times in a day by a timer. CONSTITUTION:An automatic maintenance operation generating function 110 is operated by a timer 100, and a comparator 140 carries out the comparison between a starting frequency setting memory device 120 and a starting frequency counter 130 which memorizes the number of times of start in the actual arbitrary time, and the number of times for the maintenance operation is calculated. The result of the calculation is input into an automatic maintenance operation instruction device 160, and automatic maintenance operation is carried out in the number of times for the maintenance operation, and when the operation is completed, the starting frequency counter 130 is reset by a reset signal 170, and the starting frequency is set to zero. While, an operation instruction 300 transmitted from the automatic maintenance operation generating function 110 is sent into an elevator operation function 180, and an elevator is operated by an elevator operating device 310, and the number of times of operations is feedback-operated into the automatic maintenance operation generating function 110 through a transmission line 320 for counter.

Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to an elevator control device, and provides an elevator that performs suitable maintenance operation by automatically operating an elevator that is rarely used or has a negative effect on the elevator. Regarding a control device.

[Conventional technology]

Conventionally, as described in Japanese Unexamined Patent Publication No. 51-137257 and Japanese Unexamined Patent Publication No. 53-18150, elevators are operated by the elevator user by operating a signal input device, etc. inside the car or at the entrance/exit of the hall. A car call signal was sent to the elevator control panel, which started the elevator operation.

[Problem to be solved by the invention]

In the above-mentioned conventional technology, when operating the elevator at the beginning of the day, the manager and the driver operate the elevator back and forth several times to check whether it is normal or not. In addition, if the driver was to wait on a specific floor at a specific time, the manager and driver would drive to that floor. In addition, elevators that are operated very infrequently may not operate even once a day, which is a very unfavorable condition in terms of maintenance.

An object of the present invention is to provide a device that can be operated reliably any number of times a day.

[Means to solve the problem]

The above object is distantly related by effectively and automatically performing maintenance operations any number of times per day, and by automatically operating and waiting on any floor at any time.

[Effect]

Elevator automatic maintenance operation is performed at any set time using a clock and 24-hour meter, or by remote control from the outside, so there is no possibility of malfunction.

Also, if the elevator breaks down during automatic maintenance operation,
Since the failure detection device issues a stop command and the elevator stops, the elevator does not malfunction due to failure.

〔Example〕

FIG. 1 is a circuit diagram of an embodiment of the present invention. When the time set for maintenance operation comes, contact 91 is turned on, relay 1 is turned on, and its contact 21 turns on relay 4, and the elevator is turned on. The device automatically starts moving and operates until the contact 91 turns off. At this time, when a call is registered, contacts 93 to 13 are turned on, relay 3 is turned on, and contact 31 is turned on, turning off relay 1 and disconnecting the maintenance operation command circuit, resulting in normal operation. When the call is answered, contacts 93 to 13 are turned off and relay 3
is turned off, the contact 31 is turned off, and the relay 1 is turned on again to enter maintenance operation. At this time, when the failure detection device 8 operates, the relay 6 turns on, and its contact 61 causes the relay 4 to
At the same time, the contact 62 operates the alarm device to issue an alarm. Also, when the time set for management operation comes, contact 92 turns on and relay 2
is turned on, its contact 11 is turned on, turning on the relay 4 and operating the elevator. When the elevator arrives at the designated floor, the floor detection device 97 turns on, turning on the relay 7,
Turn off relay 4 to stop operation. At the same time, the contact 72 turns off the relay 3, making it impossible to register a call.

FIG. 2 is a system diagram representative of the present invention.

The automatic maintenance operation generation function 110 is activated by the timer 100, and the comparator 140 compares the startup number setting memory 120 with the startup number counter 130, which stores the actual number of startups within a given time, and performs the maintenance operation. Calculate the power count. This calculation result is brought to the automatic maintenance operation command device 160, and automatic maintenance operation is performed for the number of times that the maintenance operation should be performed, and when the operation is completed, the activation number counter 130 is reset by the reset signal 170, and the activation number is set to O. On the other hand, the operation command 30 issued from the automatic maintenance operation generation function 110
0 is sent to the elevator operation function 180, and the elevator operation equipment! 1310, the elevator is operated, and the number of operations is fed back to the automatic maintenance operation generation function 110 through the counter communication line 320.

Further, if the elevator malfunctions during operation, the failure detection device 11200 of the failure detection function 190 transmits the signal to the stop command generation device 210, and the stop signal 330 is transmitted to the elevator operation function 180 to stop the operation. At the same time, a malfunction display 220 is displayed on the elevator hall side or any other location.
I do. Furthermore, the phenomenon of a failure is transmitted to the failure reporting device 230, and is reported to a building management system 250 within the same building or at a remote location via communication 240.

FIG. 3 is a flow diagram of the present invention. When the timer is turned on, the elevator makes an arbitrary call and performs automatic maintenance operation in accordance with the call.

FIG. 4 is a flowchart of one embodiment of the present invention.

If the timer is turned on and the floor is not called within the specified time, a call will be made for the desired floor and automatic maintenance operation will be performed while following the call. Furthermore, if a failure occurs, the elevator is stopped, a failure notification is made, and further information is displayed.

5 and 6 are flowcharts of automatic maintenance operation performed by remote control instead of the timer in FIGS. 3 and 4. FIG.

〔Effect of the invention〕

According to the present invention, unmanned management operation is possible. In addition, if a failure occurs during operation, the elevator will stop, and a failure display can be displayed, allowing safety management to be performed before using the elevator6.
