摘要
针对高速曳引式升降电梯轿厢实时状态监测对电梯原有电气结构依赖性强、监测灵敏度不高等问题,提出一种基于激光测距传感技术的电梯轿厢运行状态远程监测方法。介绍了激光测距传感技术的基本原理,基于激光测距传感技术开发设计了非接触式电梯轿厢位置、速度、加速度智能化监测系统,由此实现对电梯轿厢运行状态的远程监测。试验表明,基于激光测距传感技术的电梯轿厢运行状态远程监测方法能够实时响应、准确获取电梯轿厢的停留位置,以及运行速度、加速度信息,测量精度能够达到毫米级。
Aiming at the problems of strong dependence on the original electrical structure of the elevator and low monitoring sensitivity when monitoring the real-time status of high-speed traction elevator car,a remote monitoring method for the running status of elevator car based on laser rangefinding sensing technology was proposed.The basic principle of laser rangefinding sensing technology was introduced.Based on the laser rangefinding sensing technology,a non-contact intelligent monitoring system for elevator car’s position,speed,acceleration was developed and designed,thereby realizing remote monitoring of the running status of elevator car.Tests have shown that the remote monitoring method for the running status of elevator car based on laser rangefinding sensing technology can respond in real time and accurately obtain the stop position of the elevator car,as well as other information like running speed and acceleration and the measurement accuracy can reach the millimeter level.
