轿式电梯专用按钮的设计

The design of the car-based elevator's type button

为了提高目前轿式电梯中按钮的可靠性,本文在对现有常规电梯按钮结构的分析基础上提出了一种专门用于轿式电梯的按钮改进装置的设计。其采用了压力传感器检测按钮是否被按下,利用光敏元件检测按钮背光灯的状态,再通过总线将信息传输给电梯控制器,从而提高按钮的可靠性,避免按钮故障情况的发生。

In order to improve the reliability of the elevator button,this paper presents a design for the buttons of the lift improvement devices based on the analysis of existing conventional elevator button structure.The pressure sensor detects whether the button is pressed,the photosensitive element detection button backlight state,the information will be transmited to the elevator controller by bus,so as to improve the reliability of the button,to avoid the occurrence of failures.
