Intelligent elevator safety detection system and detection method

Abstract

The invention provides an intelligent elevator safety detection system and method. The intelligent elevator safety detection system comprises input point acquisition modules, a displacement acquisition module, a man-machine interaction module, a data processing module, a data storage module and a data analysis module. The input point acquisition modules, the displacement acquisition module and the man-machine interaction module are connected with the data processing module. The data processing module is connected with the data storage module. The data analysis module is connected with the data storage module. The intelligent elevator safety detection system integrates displacement speed detection and input point detection, and carrying and testing are convenient. A movable encoder is used for detecting the elevator speed, and when detection is conducted, only the operation that a wheel groove of the encoder is attached to a steel wire rope in an elevator machine room needs to be conducted; and when the steel wire rope moves, a runner of the encoder rotates accordingly, the displacement recording is conducted, the speed is calculated according to the displacement, and therefore the elevator displacement and speed can be accurately measured without entering of an elevator shaft.

Description

technical field [0001] The invention relates to elevator safety detection technology, in particular to an intelligent elevator safety detection system and detection method. Background technique [0002] With the increase of high-rise buildings, elevators have become more and more common in our lives, accompanied by elevator safety issues, so the importance of elevator safety testing is self-evident. [0003] Many of the current elevator safety inspection items involve the inspection of the elevator moving distance and the output response time of the elevator controller. Usually the detection of the moving distance of the elevator is by measuring the length of the marked steel wire rope, and the response time of the elevator control output is basically measured with an oscilloscope. According to the current detection method, testers need to carry more equipment, including oscilloscopes, measurement tools, measurement lines, etc., and when measuring on different sites, differ...

Problems solved by technology

According to the current detection method, testers need to carry more equipment, including oscilloscopes, measurement tools, measurement lines, etc., and when measuring on different sites, different measurement environments and measuring instruments will also lead to inaccurate measurement results, and some are harsh The test environment will also affect the use of test instruments. For example, the oscilloscope must use AC power, but some environments do not allow it; the test voltage on site includes high voltage and low voltage, DC and AC, and different probes need to be used for testing. inconvenient
