 位移传感器在电梯中的应用

       电梯是现代建筑内关系到人民生命财产安全的重要交通工具,是楼层用以固定提升的成套设备,它由提升曳引系统、引导系统、安全装置和电控系统组成。如何提高电梯的运行效率、降低电梯能耗以及减少机械磨损、延长电梯的使用寿命,都是非常重要的研究课题。目前电梯的控制普遍采用了两种方式,一是采用微机作为信号控制单元,实现电梯的自动调度和集选运行功能,拖动控制则由变频器来完成;第二种控制方式用可编程控制器(PLC)取代微机实现信号集选控制。

       电梯中向控制系统、拖动系统提供载荷、换向、障碍、位置、速度等各种信号并信号反馈给控制系统的使电梯平衡运行的装置是传感器。电梯中应用的传感器种类比较多。如:位移传感器、称重传感器、光幕传感器、平层传感器、速度编码器等。位移传感器与平层传感器是电梯平层控制调整的装置,实现自动平层,且平层必须准确。适应频繁起动、停止、调整及换向的工作要求,使加、减速和等速平稳,速度曲线平滑,到站前无微动。

        Elevator is an important vehicle related to the safety of people's life and property in modern buildings. It is a complete set of equipment for fixed lifting of floors. It is composed of lifting and towing system, guiding system, safety device and electric control system.How to improve the efficiency of elevator operation, reduce energy consumption, reduce mechanical wear and prolong the service life of the elevator, are very important research topics.At present, elevator control is generally used in two ways, one is the use of microcomputer as a signal control unit, to achieve automatic dispatching and set operation functions of the elevator, drag control is completed by the inverter;The second control mode USES PLC to replace microcomputer to realize signal set selection control.

 

 

        In the elevator, the sensor is the device that provides load, reversing, obstacle, position, speed and other signals to the control system and drag system, and the signals feed back to the control system to make the elevator run in balance.There are many kinds of sensors used in elevators.Such as: displacement sensor, weight sensor, light screen sensor, flat sensor, speed encoder, etc。The displacement sensor and the horizontal sensor are the elevator horizontal layer control adjustment device, realizes the automatic horizontal layer, and the horizontal layer must be accurate.Adapt to the requirements of frequent start, stop, adjustment and commutation, make acceleration, deceleration and constant speed smooth, speed curve smooth, no twitching before the station.
