一种新的自动扶梯防逆转监测方法

A New Monitoring Method to the Anti Unintentional Reversal of the Direction of Travel of Escalators

列举了检验机构对自动扶梯防逆转保护功能的几种检测方法；分析了现有的自动扶梯防逆转保护监测的几种形武．指出了这些形式存在的不足；提出了用于防逆转保护的一种新的速度监控相位法——双传感器安装于梯级棱对面监测法，分析了该方法的设计原则，并进行了试验测量。

Several monitoring methods of inspection units on the anti unintentional reversal of the direction of travel of escalator are listed. Several forms of the existing escalators protecting and monitoring are analyzed and the shortcomings of these forms existed are pointed out. A new speed monitoring phase method, namely dual sensor installed in step edge opposite monitoring method for the anti reversal of the direction of travel is proposed. The design principles of the method are analyzed and the experimental measurements are carried out.
