Abstract：To accurately and dynamically obtain the wind speed and air volume of the underground wind station,an anthropomorphic measurement system for roadway wind speed was developed.The system uses an electric motor as the driving force and a mechanical anemometer as the measurement means,integrating a controller,display board,alarm,and camera to achieve automatic counting,resetting,and six-line trajectory airflow measurement,AI-based intelligent recognition of the anemometer dial,and synchronized release of measurement results both underground and on the surface.The main body of the measuring device is a single supporting cantilever beam structure primarily made of carbon fiber,characterized by light weight,easy installation,and convenient storage.Through developing the mine intrinsically safe actuator,the wireless automatic control of mechanical anemometer automatic counting and resetting is realized.Based on the dynamic geometric relationship between the anemometer and the motor,a mathematical model for inverse calculation of"anemometer trajectory→motor rotation stroke"is established,enabling automatic six-line wind measurement.The system underwent industrial trials at Cilinshan and Yanbei Coal Mines.Using the results of tracer gas airflow measurement as the standard,the feasibility of replacing manual measurement with the device was analyzed:the measurement results of the device were consistent with the tracer gas airflow measurement results in terms of variation trend,with an average measurement error of less than 5%.The anthropomorphic airflow measurement system can replace manual measurement,achieving"one-click airflow measurement"and accurate,dynamic acquisition of full-section roadway wind speed.
