Diagnosis operation device and method of elevator

Abstract

The invention relates to diagnosis operation device and method of an elevator. A reference mode corresponding to the environmental temperature, the traveling status and the like before an earthquake occurs is set before diagnosis operation is implemented, and the abnormity detection precision in diagnosis operation can be greatly improved. The diagnosis operation is carried out after control operation in the earthquake is implemented, i.e. a lift car of the elevator travels, preset elevator equipment is simultaneously measured, and a measured value and the reference mode are compared to judgewhether the equipment is abnormal or not. Before the earthquake occurs, the reference mode corresponding to the equipment is prestored in a reference mode storage part (3). In the preset period afterthe earthquake occurs, the variation is measured when the reference mode corresponding to the equipment is relatively stored in the reference mode storage part (3). Then, the reference mode corresponding to the equipment is reset before the diagnosis operation starts according to the reference mode stored in the reference mode storage part (3) before the earthquake occurs and the variation obtained in the preset period after the earthquake occurs.

Description

technical field [0001] The present invention relates to an elevator diagnosis operation device and a diagnosis operation method for performing a diagnosis operation in order to restart the operation of the elevator after the earthquake control operation is performed. Background technique [0002] In an elevator equipped with an earthquake detector, when shaking of an earthquake is detected, an earthquake control operation called stopping at the nearest floor to rescue passengers is performed according to the scale of the earthquake (magnitude of acceleration of the building, etc.). In addition, depending on the scale of the earthquake, some of the following abnormalities may occur in the elevator shaft: the car and the counterweight are detached from the guide rails, the joints of the guide rails are deformed, or ropes and cables are caught in the shaft. On the protrusions in the road. Therefore, in the past, when some kind of abnormality may occur in the elevator due to th...

Problems solved by technology

However, in the gear transmission (ギア-ド, geared) type (such as turbine) hoisting machines, etc., the torque current and the like will also change due to the ambient temperature and the traveling conditions before the earthquake, such as air temperature, elevator operating rate, etc. When the diagnostic operation is performed at night when the temperature and operating rate are both low, and during the diagnostic operation during the day when the temperature and work rate are high, the torque current will have a large difference

Therefore, even if a reference pattern is set for each device and the reference pattern is regularly learned, the width of the reference pattern needs to be set relatively large, so it is difficult to improve the accuracy of abnormality detection during diagnostic operation

[0010] In addition, the diagnostic operation described in Patent Document 1 simply compares the measured value of the sound with a predetermined three-level reference level to determine whether there is an abnormality. According to this description, no specific solution to the above-mentioned problem can be derived.
