The invention discloses an elevator limit switch auxiliary monitoring method. The method comprises the following steps that firstly, the maximum allowable distance H between an elevator counterweight and the upper end face of a counterweight buffer when an elevator car runs to a top floor is acquired, and the distance, namely the upper limit distance h0, between a car sill and a landing door sill on the topmost floor when the elevator car moves upwards until an upper limit switch acts is acquired; secondly, the distance hx between the elevator counterweight and the upper end face of the counterweight buffer is detected when the elevator car runs to the top floor; and thirdly, whether hx meets the condition that hx is larger than h0 and smaller than or equal to H or not is judged, if yes, the elevator runs normally, and if not, alarm information is sent to elevator maintenance personnel. According to the method, the position of the elevator counterweight is monitored in real time, the position of a counterweight lower collision plate can be limited within a range, and therefore a limit switch, especially the upper limit switch, can play a better role.

    本发明公开了一种电梯极限开关辅助监测方法,包括以下步骤:步骤一,采集电梯轿厢运行至顶层时,电梯对重与对重缓冲器上端面之间的最大允许距离H,采集电梯轿厢上行至上极限开关动作时,轿厢地坎与最顶层层门地坎之间的距离,即上极限距离h0;步骤二,当电梯轿厢运行至顶层时,检测电梯对重与对重缓冲器上端面之间的距离hx;步骤三,判断hx是否满足h0
