The invention discloses an elevator landing door lock protection method. The method is achieved based on a host, first sensors, second sensors and electric magnetic mechanisms, wherein the corresponding first sensor and the corresponding second sensor are arranged at the upper end and the lower end of a corresponding landing door of each landing, the electric magnetic mechanisms are arranged on landing door locks correspondingly, the first sensors and the second sensors detect a signal of an elevator car in real time and transmit the detected signal to the host, a working state of the host isset, whether the elevator car is located at a set position or not is judged according to the selected working state and the received signal, if the elevator car is located at the set position, the signal is sent out, the electric magnetic mechanism of the corresponding landing door is controlled to act, and unlocking of the corresponding landing door lock is achieved, and if the elevator car is not located at the set position, the corresponding electric magnetic mechanism is reset and does not act. The method ensures the safety of rescue, maintenance or personnel in the elevator car, and avoids potential safety hazards.
本发明公开了电梯层门锁防护方法,基于主机,分设在每层站层门上下端的第一、第二传感器及设置在层门锁上的电动磁力机构实现,第一、第二传感器实时检测电梯轿厢的信号,并把检测到的信号传送给主机;设定主机的工作状态,根据选定工作状态和接收到的所述信号判断电梯轿厢的位置是否在设定位置;若在设定位置,则发出信号,控制本层站层门的电动磁力机构动作,实现本层站层门锁的开启;若不在设定位置,则电动磁力机构复位不动作;确保救援、维修或者轿厢内人员的安全,避免安全隐患。
