摘要
随着我国国民生活水平的不断提高,电梯成为人们日常生活中随处可见的设备。电梯在为人们的生活带来便利的同时,也存在诸多安全隐患。其中,电梯门回路故障就是一种常见的电梯故障,为了保障公众的生命安全,相关责任单位应当定期做好电梯门回路故障检测功能,一旦发现电梯门回路中存在故障,则应当立即切断电梯运行。重点介绍了电梯的一种典型的门回路检测逻辑电路,使用逻辑判断方法实现功能,并围绕电梯门回路检测原理介绍了门回路检测的检验方法。最后分析了一则贯通门电梯的改造案例,发现其未对改造的贯通门增加相应门回路检测功能,导致无法在该侧实现相应功能,经过重新设计电路板及程序,促使门回路检测系统能同时保证贯通门侧和正常层门侧有效,为相关实践工作提供借鉴和帮助。
With the continuous improvement of China′s national living standards,elevator has become a ubiquitous equipment in people′s daily life. Elevator brings convenience to people′s life,but there are also many security risks. Among them,the elevator door circuit fault is a common elevator fault,in order to protect the public′s life safety,the relevant responsible units should regularly do a good job in the elevator door circuit fault detection,once found in the elevator circuit fault,it should immediately cut off the elevator operation. A typical door loop detection logic circuit diagram of elevator was focused on,which used logic judgment method to realize the function,around the principle of elevator loop detection,the detection method of door loop detection was introduced,and a transformation case of through door elevator was analyzed,which caused by the failure to add corresponding door loop detection function to the transformed through door. Finally,through redesigning the circuit board and program,the door loop detection system could ensure the effectiveness of through door detection and normal floor door detection at the same time,which could provide some reference and help for the relevant practical work.
