Abstract: In order to make the coal mine belt conveyor run more smoothly and reduce energy consumption, an advanced coal
flow detection system was designed. Through the establishment of Siemens open user communication, the coal flow on the
conveyor belt can be better detected. After on-site application, when the load of the conveyor changes several times, the driving
speed remains unchanged; when there is a significant change in load, the method of adjusting the driving speed of the conveyor is
adopted to reduce energy consumption and wear of the conveyor, and to fully utilize the trapezoidal speed adjustment strategy of
the frequency converter function.

Key words: belt conveyor; coal flow; coal flow detection system
