Summary:A mining intrinsic safety speed sensor control circuit is characterized by comprising a frequency output circuit (1), a speed control circuit (2) and a nixie tube display circuit. The frequency output circuit (1) is mounted in a roller of a mining intrinsic safety speed sensor, a frequency quantity output end of the frequency output circuit (1) is connected with a signal receiving end of the speed control circuit (2), and a nixie tube (3) is connected with a display output end of the speed control circuit (2). The mining intrinsic safety speed sensor control circuit is convenient to use and convenient for underground maintenance, a support is fixed onto a belt conveyor support by steel cables of the support to enable the roller to freely fall on a belt, equipment tightness is fine, and the mining intrinsic safety speed sensor control circuit is simple in mechanism and basically belongs to maintenance-free products.
