The invention relates to a floor staggering prevention electrical system, a floor staggering prevention implementation method using the system and an elevator comprising the system. The mistake-proofing electrical system comprises a collision bow, a plurality of travel switches and an electrical interlocking device, wherein the collision bow is arranged on a portal frame of a lift car and can move together with the lift car; the plurality of travel switches are respectively fixed on a car guide rail in a hoistway and are arranged to respectively correspond to the setting positions of the collision bow when the car stops at the leveling position of the corresponding floor, when the collision bow is in contact with the corresponding travel switch, the corresponding travel switch is triggered, and each travel switch is provided with a first group of contacts and a second group of contacts; the electrical interlocking device can be electrically connected with the first set of contacts of the corresponding travel switch, and when the electrical interlocking device is electrically connected with the first set of contacts of the corresponding travel switch, the electrical interlocking device is powered. The mistake-proofing electrical system is used as a set of independent peripheral electrical judgment system to cooperate with the CPU to perform redundancy, so as to prevent the elevator door lock from malfunctioning once the CPU breaks down or is in disorder.
本发明涉及防错层电气系统、利用该系统的防错层实现方法以及包括该系统的电梯。该防错层电气系统包括撞弓、多个行程开关和电气互锁装置,撞弓设置于轿厢的龙门架上且能够与轿厢一起移动;多个行程开关分别固定在井道内的轿厢导轨上,布置为分别对应于轿厢停靠在相应楼层的平层位置时撞弓的设置位置,当撞弓与相应行程开关接触时,相应行程开关被触发,每个行程开关具有第一组触点和第二组触点;电气互锁装置能够与相应行程开关的第一组触点电连接,当与相应行程开关的第一组触点电连接时,电气互锁装置被供电。防错层电气系统作为一套独立的外围电气判断系统来配合CPU进行冗余,防止CPU一旦发生故障或者错乱时使电梯门锁误动作。
