摘要
针对现有电梯制动器难以通过可靠的仪器进行现场检测的状况,设计了便携式电梯制停参数检测装置。采用基于飞行时间(TOF)的测距技术和微机电(MEMS)电容式加速度传感器的测量原理对电梯制停过程中的制停距离和平均制停减速度进行测量,结合制停时间,综合判断电梯制动性能。试验结果表明,该装置测得电梯加速度与现有方法测试结果吻合,制停距离测量误差更小,为检验人员进行电梯制停参数检测提供了新方法。
Based on the status that the elevator brake can not be detected by reliable instruments,one kind of portable parameter detection device for elevator is designed. Principles of the time of flight（ TOF） technology and micro-electromechanical（ MEMS） capacitive acceleration sensor are applied to measure the stopping distance and the mean deceleration of the elevator and combined with the stopping time,the elevator braking performance can be evaluated.The results show that the acceleration test value of the designed device is consistent with the existed one and the measurement error of stopping distance is smaller. It can provide a new method for the elevator stopping parameter detection.
