For problems of non-comprehensive monitoring data and large volume and inconvenient installation of flameproof type monitoring equipment existed in running status monitoring system for scraper conveyor in fully mechanized working face, a running status monitoring system of scraper conveyor was developed, and software and hardware design schemes of substation of the system were introduced in details. The substation, which is composed by CPU, data acquisition module and communication module, can monitor running status of driving equipments for scraper conveyor, and diagnose load status of scraper conveyor by use of input and output speed monitoring method for torque limiter. The test result shows that the substation meets intrinsically safe requirements, and has accurate monitoring data, stable communication and reasonable and effective diagnosis method of load status.
