Research on Recognition and Control Technology of Coal Mine Inclined Shaft Running Cars

The phenomenon of coal mine running cars is a common type of accident in inclined shaft transportation. Early prediction and active control of running cars are of utmost importance in improving the level of running car protection. This article applies a radar system to the recognition of inclined shaft running cars, obtaining real-time mining and industrial information, automatically detecting whether the locomotive has stall, overspeed and other situations, and assisting the running car protection device to intercept it in the first time. The signal-to-noise ratio of the three target echoes measured by the radar is not less than 20dB, and the filtering algorithm can meet the speed measurement requirements, verifying the feasibility of the running car recognition method. In the aspect of active control, matrix based interlocking control strategy is adopted, and intuitive control strategy is obtained by using the multi section division method of running lines, which simplifies the interlocking logic relationship, realizes the intelligent dispatching of all track trains, and verifies the feasibility and progressiveness of the control of rail transport vehicles.
