Abstract:

In order to accurately and dynamically obtain the wind speed and air volume of the underground wind station, a set of anthropomorphic measurement system for roadway wind speed was developed. The system uses the motor as the driving force and the mechanical wind meter as the wind measurement means. The controller, display board, alarm, and camera work together to realize the automatic clutch and zero return of the mechanical wind meter. The mechanical wind meter automatically measures wind according to the six-line trajectory. The dial of the mechanical wind meter is intelligently recognized by AI, and the wind measurement results are released simultaneously underground and above the well. The main body of the wind measuring device is a single supporting cantilever beam structure made of carbon fiber as the main material, which has the characteristics of light weight, easy installation and easy storage. Through simulation and theoretical calculation, the maximum bending subsidence of cantilever beam is determined to ensure that the slider can slide on the slide rail without obstacles. Through the development of mine intrinsically safe actuator, the wireless automatic control of mechanical wind meter counting and zeroing is realized. Based on the dynamic geometric relationship between the wind meter and the motor, a mathematical model of the inverse solution of "wind meter trajectory → motor rotation stroke" is established to realize the autonomous six-line wind measurement of the wind meter. The system has been tested industrially in Cilinshan Coal Mine and Yanbei Coal Mine. Taking the results of tracer gas air volume measurement as the standard value, the feasibility of device wind measurement instead of manual wind measurement is analyzed: The wind measurement results of the device are consistent with the tracer gas air volume measurement results in terms of changing trend and fluctuation, and the average wind measurement error is less than 5%. The anthropomorphic wind measurement system can replace manual wind measurement and realize "one-click wind measurement". Accurately and dynamically obtain the wind speed of the whole section of the tunnel.
