摘要:

为了准确动态获取井下测风站的风速风量,研制了一套巷道拟人化测风系统。该系统以电机为驱动力,以机械风表为测风手段,协同控制器、显示牌、报警器、摄像仪实现风表自动计数、回零与六线法测风,风表表盘AI智能识别,测风结果井下井上同步发布。测风装置主体是以碳纤维为主材的单一支撑悬臂梁结构,具备重量轻、易安装、好收纳特点;通过研制矿用本安执行器,实现了机械风表计数和回零的无线自动控制;基于风表与电机的动态几何关系,建立了“风表轨迹→电机转动行程”逆解算的数学模型,实现风表自动六线测风。该系统在慈林山和砚北煤矿进行了工业性试验,以示踪气体风量测定的结果作为标准值,分析了装置测风替代人工测风的可行性:装置测风结果与示踪气体风量测定的结果在变化趋势上保持一致,测风平均误差小于5%,拟人化测风系统可取代人工测风,实现“一键测风”,准确动态获取巷道全断面风速。

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.
