On-line monitoring system of working face footage based on radar ranging

  • 摘要: 传统的静态人工测量技术获取的工作面进尺非连续、时效性差,无法满足在线实时预警的要求,针对该问题,设计了基于雷达测距的工作面进尺在线监测系统。该系统采用应答式和反射式雷达测距传感器组合布置工艺,克服了反射式测距雷达测量距离小的不足,解决了应答式测距雷达安装维护困难、难以实时测距的问题。分析了雷达测距原理,并开发了由反射式和应答式雷达测距传感器构成的矿用本质安全型雷达测距传感器。测试结果表明,该系统能够稳定、可靠地实现工作面进尺在线监测、实时采集与分析,当测量距离小于200 m时,最大绝对误差为0.24 m,测量距离和精度能够满足瓦斯灾害预警的要求。
    Abstract: The working face footage acquired by traditional artificial static measurement technology has non-continuous and poor time-effectiveness, and ca't satisfy requirement of on-line real-time warning. For the above problem, an on-line monitoring system of working face footage based on radar ranging was designed. The system uses combination arrangement process of response radar ranging sensor and reflection radar ranging sensor to overcome shortcomings of short measuring range of the reflection radar and solve problem of difficult installatipn and maintainance of the response radar. Principle of the radar ranging was analyzed, and mine-used intrinsically safe radar ranging sensor composed of the reflection radar ranging sensor and response radar ranging sensor was developed. The test result shows that the system can stably and reliably realize on-line monitoring, real-time collection and analysis of working face footage. When measuring distance is less than 200 m, the maximum absolute error is 0.24 m, and the measuring distance and accuracy can meet the needs of gas disaster early warning.
