摘　　要：自动扶梯与自动人行道作为高集成度的特种设备,对于扶手带及梯级速度的检测都是使用的精度不高的方法,针对该现象,设计一款自动扶梯扶手带及梯级速度无线监控装置,在扶梯牵引轮和扶手驱动轮一侧加装传感器,并通过无线通信的方式进行信号传输,当检测到的自动扶梯梯级速度或扶手带速度信号超过预设值时,指示灯亮红灯并且蜂鸣报警器鸣叫报警,同时控制扶梯停止。这样的设计可以避免线缆发生绞线事故,并提高自动扶梯与自动人行道的可靠性和安全性。Escalators and moving walks are highly integrated special equipment,and the handrail and step speeds are detected using methods with low accuracy.For this phenomenon,a wireless monitoring device for the handrail and step speeds of the escalator is designed,sensors are installed on one side of the escalator traction wheel and handrail drive wheel,and signals are transmitted through wireless communication.When the detected signals of the escalator step speed or handrail speed exceed the preset value,the indicator light will turn red,the buzzer will beep to alarm,while the escalator will be controlled to stop.This design can avoid cable stranding accidents and improve the reliability and safety of escalators and moving walks.
