Description
技术领域technical field
本申请实施例涉及站台门系统领域,尤其涉及一种站台门系统安全回路电路。The embodiments of the present application relate to the field of platform door systems, and in particular, to a safety loop circuit of a platform door system.
背景技术Background technique
地铁以其快速、准时、方便、舒适等优点,已经成为现代城市的公共交通的主要发展方向。而轨道站台门的控制作为地铁安全系统中较为关键的组成部分,直接关系并影响到地铁运行的安全性、可靠性。With its advantages of speed, punctuality, convenience and comfort, subway has become the main development direction of public transportation in modern cities. The control of the rail platform door, as a key component in the subway safety system, is directly related to and affects the safety and reliability of the subway operation.
现有技术中通过设置安全回路对地铁的站台门进行安全监测,在滑动门、应急门、端门上都安装有门关闭锁紧开关,门关闭锁紧开关及必要电路形成安全回路,所有门单元的安全回路单元串联起来,并且返回到站台门控制器中,形成站台门控制系统关闭锁紧安全回路。In the prior art, the safety monitoring of subway platform doors is carried out by setting up safety circuits. Door closing locking switches are installed on sliding doors, emergency doors and end doors. The door closing locking switches and necessary circuits form a safety circuit. The safety circuit units of the unit are connected in series and returned to the platform door controller to form the platform door control system to close and lock the safety circuit.
而目前的站台门安全回路设计中存在控制电路不稳定导致站台门不能正常工作的问题。目前站台门安全回路设计存在的控制电路不稳定包括行程开关触点抖动、行程开关触点不同步以及单一触点故障导致整侧安全回路工作异常等。行程开关触点抖动是当行程开关安装不到位或者老化时,行程开关动作时容易出现信号抖动,一旦有开关抖动则整条安全回路信号状态将不稳定。发生行程开关触点抖动时,由于信号系统检测到站台门安全回路状态跳变,则判定站台门状态为不安全状态,不允许列车进出站,需要通过人工操作站台控制盘上的互锁解除设备,才能让列车进出站。而且行程开关触点抖动这种情况往往是一闪而过,排查和定位都很难。正常情况下,行程开关触点为同步触发,在行程开关老化或安装不到位处于临界位置时,行程开关的触点组会出现不同步的情况。目前的站台门安全回路设计是由所有站台门行程开关触点串联组成,主路上任意一组行程开关故障如触点损坏、接触不良等,将造成整侧安全回路工作异常,需人工排查后将该滑动门安全回路进行短接旁路,维修后才能让滑动门恢复正常工作。However, in the current platform door safety circuit design, there is a problem that the control circuit is unstable and the platform door cannot work normally. At present, the instability of the control circuit in the design of the platform door safety circuit includes the jitter of the travel switch contacts, the asynchronous contact of the travel switch, and the abnormal operation of the entire safety circuit caused by a single contact failure. The contact jitter of the travel switch means that when the travel switch is not installed properly or is aging, the signal jitter is prone to occur when the travel switch is in action. Once the switch jitters, the signal state of the entire safety circuit will be unstable. When the contact of the travel switch vibrates, because the signal system detects the state jump of the safety circuit of the platform door, it is determined that the state of the platform door is unsafe, and the train is not allowed to enter or leave the station. It is necessary to manually operate the interlock release device on the platform control panel. to allow the train to enter and exit the station. Moreover, the situation of the contact vibration of the travel switch is often a flash, and it is difficult to troubleshoot and locate. Under normal circumstances, the contacts of the travel switch are triggered synchronously. When the travel switch is aged or installed in a critical position, the contact group of the travel switch will be out of synchronization. The current platform door safety circuit design is composed of all platform door travel switch contacts connected in series. Any group of travel switch failures on the main road, such as contact damage, poor contact, etc., will cause the entire side of the safety circuit to work abnormally. The sliding door safety circuit is short-circuited and bypassed, and the sliding door can be restored to normal operation only after maintenance.
