Abstract

The invention discloses an over-temperature detection system of a belt conveyor roller and a control method of the over-temperature detection system, relating to the technical field of conveying machine measurement and control. According to the over-temperature detection system of the belt conveyor roller, fire is prevented by detecting the temperature of a roller bearing and executing a protection instruction. The over-temperature detection system comprises a roller group, an over-temperature detection unit and an industrial personal computer; the roller group comprises a plurality of rollers and a bracket; the over-temperature detection unit is in communication with the industrial personal computer through a CAN bus and comprises an over-temperature switch, a single chip microcomputer and a CAN bus transceiver chip; and the over-temperature switch is pasted to the roller bearing. Deformation is generated through a two-way shape memory alloy spring at a specific temperature and on-off of a circuit is achieved; and the single chip microcomputer and the CAN bus transceiver chip are packaged in a ceramic box and are arranged on the bracket of a support roller. According to the over-temperature detection system, the automatic detection of over-temperature of the belt conveyor roller is achieved, the over-temperature detection system is stable to operate, low in cost and suitable for massive application, and a fire hazard is completely eradicated effectively.
