Development of Novel Detector of Disk Brake in Coal Mine

In order to solve problems of few stored data and lack of communication function of existing detectors of disk brake in coal mine, the paper proposed a design scheme of novel detector of disk brake based on μPSD3354 microprocessor and ADS7957 A/D chip. The detector can automatically detect and real-timely display parameters of working status of disk brakes. When brake clearance exceeds the specified value, the detector will give sound and light alarm and show the exceeding brake. Besides, the detector can store data detected in a year, and transmit the historic data to upper computer. The testing result showed that the detector runs stably and reliably.
