Laser radar-based elevator attitude recognition system and method

Abstract

The present invention discloses a laser radar-based elevator attitude recognition system and method. The system comprises at least two laser radars. One of the laser radars is arranged at the bottom center of the elevator car, and the remaining laser radars are arranged at the bottom edge of the elevator car. The power input end of each laser radar is connected with a power module through a relay;the data output end of each laser radar is connected with the I / O port of a processor; and the signal output end of the processor is connected with a voice output device. By setting a plurality of laser radars on the elevator car and matching the setting signs, calculation is performed by using the processor according to the data obtained after scanning by using the respective laser radar, the speed and the offset angle of the real-time operation of the elevator car can be determined, and the elevator attitude can be accurately recognized in real time; and when the speed and the offset angleare greater than the preset values, the voice output device is controlled by using the processor to emit an alarm sound, and the elevator accident is eliminated before the occurrence, so that the safety factor of the elevator operation is greatly improved, and the technical scheme of the preset invention is worth promoting.

Description

technical field [0001] The present invention relates to the technology in the field of elevators, in particular to a lidar-based elevator pose recognition system and method. Background technique [0002] A vertical elevator has a car running between at least two vertical or inclination angles of less than 15° rigid guide rails. The size and structure of the car are convenient for passengers to enter and exit or to load and unload goods. It is customary to use elevator as a general term for vertical transportation in buildings regardless of its driving mode. According to the speed, it can be divided into low-speed elevators (below 4 m / s), fast elevators (4-12 m / s) and high-speed elevators (above 12 m / s). [0003] Various parameters will be generated during the operation of the vertical elevator, among which the speed and deflection angle are one of the two important parameters, which determine the posture of the elevator car and have a direct impact on the operation safety ...

AI Technical Summary

Problems solved by technology

However, there is currently no system that can accurately identify the elevator position in real time, and cannot prevent elevator accidents before they occur.
