摘　　要：电梯运行中经常出现轿厢的意外移动故障现象,严重威胁人员的生命安全。为此,在当前电梯结构组成及轿厢意外移动故障原因分析的基础上,采用PLC控制器,从总体方案、硬件系统、软件系统等方面开展了检测及保护装置的设计及实际应用研究。运行效果显示,该保护装置运行良好,能较好地实现对电梯卡阻、封接故障等故障现象进行实时检测,并执行相关的安全保护措施和发出报警提示,降低了电梯的安全事故,具有重要的实际应用价值。During the operation of the elevator,the unexpected movement of the car often occurs,which seriously threatens the life safety of people.Therefore,based on the analysis of the current elevator structure composition and the cause of the car accidental movement fault,the design and practical application of the detection and protection device were carried out from the overall scheme,hardware system,software system and other aspects by using PLC controller.The operation results show that the protection device runs well,and can better realize the real-time detection of elevator jam,sealing fault and other fault phenomena,and implement the relevant safety protection measures and send out alarm prompts,which reduces the safety accidents of the elevator,and has important practical application value.
