The invention discloses a speed measurement control device of a coke mine hoist. The speed measurement control device of the coke mine hoist comprises a front-end hoist module, a magnetic rotary encoder speed measurement module, a connection visualization module and a control feedback module. The front-end hoist power module comprises a reduction motor and four disc brakes, the reduction motor isarranged on one side of a steel wire fixed pulley of the hoist, and the four disc brakes are all arranged at one end of a brake disc of the hoist. The magnetic rotary encoder speed measurement modulecomprises a permanent magnet rotary drum, a magnetic resistance probe and a signal amplification circuit. The connection visualization module comprises an A/D converter, a filter circuit and an oscilloscope. The control feedback module is developed and designed based on the FPGA. The speed measurement control device is applied to the reduction motor of the coke mine hoist, the magnetic rotary encoder scheme is adopted, a contactless magnetic encoder chip is used, a plurality of peripheral devices of the magnetic encoder are omitted, the size is smaller, the cost is lower, the safe production level of coal is effectively improved, and the personnel safety and production safety are ensured.
