Gyroscope based elevator platform speed measuring system and method

Abstract

The invention provides a gyroscope based elevator platform speed measuring system. The system comprises a gyroscope signal acquiring unit, a gyroscope signal analyzing unit, a speed signal comparing unit, a vibrating signal comparing unit, alarming units and a big data platform, wherein the gyroscope information acquiring unit is connected to the gyroscope signal analyzing unit; the gyroscope signal analyzing unit is connected to the big data platform, the speed signal comparing unit and the vibrating signal comparing unit; the speed signal comparing unit and the vibrating signal comparing unit are correspondingly connected to the alarming units; in case of abnormal conditions, an alarming signal is sent to the corresponding alarming unit which is connected to an elevator maintenance and protection department; after receiving the alarming signal, the alarming units send alarming signals to the corresponding elevator maintenance and protection departments. The invention also provides agyroscope based elevator platform speed measuring method. According to the system and the method, the comprehensive detection method of gyroscope parameters is utilized, so that the elevator running state can be accurately reflected, and as a result, the damage caused by elevator risks and faults can be effectively prevented.

Description

technical field [0001] The invention relates to the field of elevator speed measurement, in particular to a gyroscope-based elevator platform speed measurement system. Background technique [0002] The elevator is now an important means of building transportation, and the running speed of the elevator is an important parameter for the operation of the elevator. It can obtain the running height of the elevator, whether it is overspeed, etc. Therefore, it is very important to detect the running speed of the elevator. The existing elevator state detection method only conducts regular manual inspection, etc., and there is no real-time elevator car system vibration data data reporting. Or only for video and audio data collection in the car, without vibration analysis when the elevator car is running, to accurately judge the status of the elevator. [0003] For example, Chinese patent application CN201110424438.9 discloses a method, device and system for measuring the speed of a...

AI Technical Summary

Problems solved by technology

First of all, the range of action of the ultrasonic velocimeter is limited, and the power consumption required to maintain a certain range of action is relatively high

In addition, for the vibration generated during the daily operation of the elevator, if there is an abnormality (such as abnormal operation of the elevator motor, abnormal mechanical state such as elevator car collision), there is no feedback
