采用WLAN通讯方式的机械式停车设备接入点切换的安全问题

Safety of access point switch of mechanical parking equipment with WLAN communication method

部分大型机械式停车设备采用WLAN作为监控通讯形式甚至指令通讯形式。由于停车设备尺寸以及结构的局限性必然涉及到接入点切换的问题,而接入点切换所产生的延时及切换"陷阱"会对立体车库的运行带来一定的安全隐患。文中就这种接入点切换机制进行了分析,并对所带来的安全问题进行了探讨。

For some large-scale parking equipment,WLAN is used in monitoring communication,even in command communication. As limitations of the size and structure of the parking equipment involve the switching of access point,any delay resulting from the switching of access points and switching ＂trap＂may bring certain hazard for the running of stereo garages. The paper analyzes the switching mechanism of access points and discusses resulting safety problems.
