Temperature Intelligent Monitoring of Brake Disk of Coal Mining Mechanism Based on Fiber Grating Sensor
With the development of intelligent brake disc of coal mining mechanism,the existing monitoring methods can not ac-curately capture the potential faults in the operating state of the brake disc.To this end,a fiber grating sensor which can be used for multi-parameter testing of intelligent brake disc is designed.A stainless steel encapsulated fiber grating temperature sensor is selected to characterize its test performance,and the test results are fitting analyzed by least square method.The re-sults show that at the same temperature,the temperature sensor forms a similar central wavelength,which achieves good re-peatability.The sensitivity curve forms a nearly linear curve,and the temperature sensor can obtain the ideal linearity,which can meet the requirements of the brake disc oil temperature test.The fiber grating temperature sensor can achieve the safety and reliability requirements of the brake disc of coal mining mechanism when the oil temperature is detected,and has a signifi-cant advantage in the monitoring of the brake disc.
