浅谈电梯轿厢井道绝对位置检测系统在电梯上的应用

APPLICATION OF THE ELEVATOR USING CAR ABSOLUTE POSITION IN WELL TESTING SYSTEM

电梯轿厢井道绝对位置检测系统．是一种独立于电梯控制系统的电梯安全装置．通过安装在轿厢的位置检测传感器．实时监测轿厢在井道的位置及速度．当检测到电梯超速或终端超速时．该系统能独立断开安全回路。由于其对轿厢的绝对位置能实时检测．所以能先于电梯控制系统判断轿厢出现意外移动情况．及时启动保护装置。

The elevator car absolute position in well testing system is a safety device for an elevator which is independent of the elevator control system, through the installation of the elevator car position detection sensor, the position and speed of real-time monitoring of the car in the well; when detecting that the elevator over speed or terminal position exceeding the speed limit, this system can independently disconnect the safety loop. Because of the absolute position of the elevator car can real-time detection, so it can precede the elevator control system to judge the car appear accidental movement, starting protection device in time.
