The invention relates to an alarm detecting method and system for trapped-in-elevator accidents. The system comprises a main control panel center processing unit (CPU), a door machine monitoring module, a speed monitoring module, an overhauling loop monitoring module, an emergency stop switch monitoring module, a timer module, an instruction registration module and a trapped-in-elevator alarm module. According to the method, through repeatedly detecting and judging whether the elevator speed is zero or not, whether an elevator is at a running state or not, whether floor instruction registration exists or not, whether an inspection switch and an emergency stop switch are started or not, whether an elevator door is in place or not, and whether an alarm bell button is started or not, and by comprehensively analyzing and judging multiple factors, the false triggering of the alarm bell button is eliminated, and the emergency stop and overhaul operation of maintenance personnel are eliminated; and an alarm is given in time through the trapped-in-elevator alarm module, so that trapped persons in an elevator car can be found in time, and meanwhile, the accuracy is higher.
本发明涉及一种电梯困人报警检测方法及系统,该系统包括主控板CPU、门机监控模块、速度监控模块、检修回路监控模块、急停开关监控模块、计时器模块、指令登记模块及困人报警模块,该方法通过多次检测判断电梯速度是否为零、并与电梯是否处于运行状态、是否有楼层指令登记以及检修开关、急停开关是否启动、电梯门是否到位、警铃按钮是否启动多种因素综合分析判断,从而排除警铃按钮的误触发以及排除维保人员急停、检修操作,并通过困人报警模块及时发出报警,从而保证了及时发现电梯轿厢中的被困人员,同时准确度较高。
