The invention provides an elevator brake shoe fault protection monitoring system, and belongs to the technical field of elevator brake shoe fault protection monitoring. The technical problem to be solved is to provide the improvement of the hardware structure of the elevator brake shoe fault protection monitoring system. According to the technical scheme, the device comprises a brake shoe abrasion indicator lamp, a spring fatigue indicator lamp, an electric bell and a storage battery which are arranged on an alarm control loop, and a brake shoe abrasion protection relay and a spring fatigue protection relay are further arranged on the alarm control loop; the first light fault protection relay and the second light fault protection relay are arranged on the fault detection loop; the fault detection loop is also provided with an isolation switch. The power input end of the alarm control loop is sequentially connected with the input end of a brake shoe abrasion indicator light, the input end of a spring fatigue indicator light, the input end of a brake shoe abrasion protection relay and the input end of a spring fatigue protection relay in parallel and then connected with the input end of a storage battery. The method is applied to elevator brake shoe fault monitoring places.
