Abstract

PURPOSE:To provide an elevator operation control device capable of storing the result of low-speed automatic operation implemented after the occurrence of an earthquake, and allowing a maintenance person to confirm the result of his/her check. CONSTITUTION:An elevator is equipped with main control devices l and 2 to control the operation of a car as well as a vibration sensor 5 to detect a vibration, and the devices 1 and 2 perform a low-speed automatic operation for detecting the condition of the elevator when the sensor 5 detects the occurrence of a vibration equal to or above the preset level. Regarding this elevator, a judgement section is provided for making judgement as to whether the low-speed automatic operation should be continued, depending on the abnormal state of the elevator detected at the time of the operation, together with a memory section 6 for storing the result of the low-speed automatic operation.

2. Description of the Related Art In a conventional elevator, when a vibration sensor such as an acceleration sensor detects a level near the lower limit of a strong earthquake, a control device mainly composed of a microcomputer for controlling the entire system suspends car operation, In this state, it waits for the inspection of the elevator including the car.

As disclosed in Japanese Unexamined Patent Publication No. 5-170387, low-speed automatic operation is performed when an earthquake occurs, and if there is no abnormality as a result, the car is stopped at the reference floor, while low-speed automatic operation is performed. If an anomaly was detected, the car would be parked there and awaiting elevator inspection.

As described above, low-speed automatic operation is performed when an earthquake occurs, and if an abnormality is detected as a result, low-speed automatic operation is interrupted and the car is suspended on the spot. However, in that case, when the elevator maintenance staff came to check later, the details beyond the interruption of low-speed automatic operation were not remembered, so it was possible to find an abnormal place. The same inspection as that performed in low-speed automatic operation must be performed again, and the inspection takes a long time. Further, since it is not known to what extent the low speed automatic inspection has been carried out, there is a possibility that the inspection may be performed again at a place where there is no abnormality as a result of the low speed automatic operation.

Therefore, the inspection after the occurrence of the earthquake takes a long time, and the number of elevators is large in the central area of the city. Therefore, one maintenance worker must inspect a large number of elevators. It takes a considerable amount of time to inspect all elevators. However, for people using elevators, we would like them to check the elevators that are stopped as soon as possible and restore them to normal.

With this structure, after the occurrence of an earthquake, the presence or absence of an abnormality in each device of the elevator is detected by low-speed automatic operation performed by a command from the elevator control device, and the determination unit is determined according to the degree of the abnormality. Determines whether to continue low-speed automatic operation, and because the results of low-speed automatic operation are all stored in the storage unit, there is no damage to elevator equipment due to low-speed automatic operation, and maintenance is also possible. Since the worker only needs to inspect the parts that could not be confirmed by low-speed automatic operation, the inspection time can be shortened and the elevator immobility time due to the earthquake can be shortened.

When an earthquake occurs, the measurement information from the earthquake detector 5 is sent to the first and second control devices 1 and 2 to determine the vibration level. Then, it is determined in step S1 whether or not the vibration level is equal to or higher than a preset first level. If the vibration level is equal to or higher than the first level, the process proceeds to step S2. If the vibration level is lower than the first level, the process proceeds to step S11 to continue normal operation. . In step S2, it is determined whether the elevator car 3 or 4 is running, and if it is running, step S2

In step S4, the car vibration level is a preset second level (a level higher than the first level. For example, if the first level is 80 gal, the second level is 120).
It is determined whether or not it is equal to or higher than the gull), and if it is equal to or higher than the second level, the process proceeds to step S5, and if it is lower than the second level, the process proceeds to step S41, and after a lapse of a predetermined time, automatically returns to continue normal operation in step S42. To do. In step S5, it is determined whether or not the car vibration level is equal to or higher than a preset third level (a level higher than the second level. For example, if the second level is 120 gal, the third level is 150 gal). If it is at the third level or higher, the process proceeds to step S6 and the third

In step S51, low-speed automatic operation is performed, and the inspection result is stored in the storage unit 6 while confirming the state of the elevator. The details of the confirmation include whether the door is open / closed normally, the car is stopped normally, etc., and these are automatically inspected, and the inspection result is stored in the storage unit 6. In step S52, the control devices 1 and 2 determine whether or not an elevator abnormality that cannot continue low-speed automatic operation is detected. An elevator state in which low-speed automatic operation cannot be continued is, for example, when the car is out of the rail or when the door is not opened or closed. If an elevator abnormality is detected such that the low speed automatic operation cannot be continued, the result up to where the low speed automatic operation is performed is stored, the reason why the low speed automatic operation cannot be continued is also stored, and the process proceeds to step S54. Step S53
Then, the control devices 1 and 2 determine whether the low-speed automatic operation is completed. When it is completed, the process proceeds to step S54. In step S54, the elevator is stopped. In step S55, the maintenance staff checks the contents displayed on the display unit 7 for inspection.

As described above, in this embodiment, even when an earthquake occurs, when the maintenance staff performs on-site inspection, the low-speed operation is automatically performed in advance to grasp and store the elevator status. The employee looks at the stored results and finds that there is an abnormal place or a place where low speed operation is not performed, and a place that cannot be checked by low speed automatic operation, for example, no foreign matter has fallen on the floor in the elevator tower. Or, check if there is any foreign object on the floor of the elevator machine room. Therefore, as a result of low-speed automatic operation,
Since it is not necessary to inspect a normal part, there is an effect that the inspection time can be shortened.
