The invention provides an elevator safety circuit fault location system which comprises a fault location module connected to connected in an elevator safety circuit and a plurality of switch assemblies. Each switch assembly comprises a switch controlled through a safety component and a capacitor corresponding to the switch. The fault location module comprises a capacitance detecting unit and a position calculation unit, wherein the capacitance detecting unit is used for detecting capacitance of the elevator safety circuit, and the position calculation unit is used for calculating the position of a switch in an off state in the elevator safety circuit according to the capacitance in the elevator safety circuit. The invention further provides a corresponding method and the location module. By arranging the capacitors for the switches in the elevator safety circuit and detecting capacitance in the elevator safety circuit, positioning of elevator safety circuit fault points is achieved, manual troubleshooting for elevator safety circuit faults is avoided, and time and labor are saved.
Description
technical field [0001] The present invention relates to the field of elevator safety, more specifically, to an elevator safety loop fault location system, method and location module. Background technique [0002] An elevator is a vertical lift powered by an electric motor, equipped with a box-like gondola, used for carrying people or goods in multi-storey buildings. In modern society, elevators have become indispensable transportation equipment. The existence of elevators makes the traffic of high-rise buildings more convenient. [0003] Since the operation of the elevator involves personal safety, in order to ensure the safe operation of the elevator, many safety components are installed in various parts of the elevator in operation and control, such as speed limiter, safety gear, emergency stop button, emergency exit switch, bottom Pit switch, limit switch and other safety components. The contacts and relays of the above-mentioned safety components are connected in seri...
