Abstract: In order to address the shortcomings of high energy consumption and poor economy in the operation of the conveyor system in Wuyang coal mine, a new low energy consumption operation control system for belt conveyors is proposed. Through non-contact coal flow visual detection technology based on laser assistance, precise monitoring of coal flow on the conveyor is achieved, and flexible adjustment of conveyor operating speed is achieved through frequency conversion control technology. The article focuses on the research of coal flow image enhancement technology and laser stripe center point extraction technology, solving the problem of poor accuracy in coal flow image recognition. According to practical applications, the new low-energy operation control system can achieve an annual electricity cost savings of 1.9845 million yuan, and save about 387000 yuan/year in parts replacement and maintenance costs.
