The invention provides an elevator car accidental movement protection device tester and system. A switch of the tester is arranged on a main machine box and connected with a brake control circuit, thebrake control circuit is connected with a power supply wiring input end of an elevator brake through a first interface, a car accidental movement signal acquisition circuit is connected with a signalinput circuit of a re-leveling door area on an elevator in series through a second interface, a processor is connected with the brake control circuit and a speed measuring sensor and used for sendinga power-off signal of the brake control circuit to the speed measuring sensor, and the processor synchronously obtains the moving direction, the moving distance and the stopping deceleration, measured by the speed measuring sensor, of a car. According to the elevator car accidental movement protection device tester and system, a test conclusion does not need to be indirectly judged by comparing detected elevator detection data with sample elevator type test data at present, so that the problem of misjudgment of the test conclusion possibly caused by inconsistent structural parameters of a sample elevator and a detected elevator is avoided, and the verification reliability is improved.

    本发明提供一种电梯轿厢意外移动保护装置测试仪、系统,该测试仪的开关设置在主机箱上,与制动器控制电路连接;制动器控制电路通过第一接口与电梯制动器的电源接线输入端连接;轿厢意外移动信号采集电路通过第二接口与电梯上再平层门区的信号输入电路串联连接;处理器分别与制动器控制电路、测速传感器连接,用于将制动器控制电路的断电信号发送给测速传感器,处理器同步获取测速传感器测量的轿厢移动方向、移动距离和制停减速度。本发明无需采用目前将被检电梯检测数据与样梯型式试验数据进行比对的方法间接判定检验结论,避免了因样梯与被检电梯结构参数不一致可能导致的检验结论错判的问题,提高了验证的可靠性。
