摘要
当前煤矿一般采用人工读取压力表数值的方法测试煤层原始瓦斯压力值,这种方法费时费力且读数误差很大。为了解决这些问题,将存储测试理论和无线传感网络技术应用于矿井瓦斯压力测试领域,提出了一种煤层原始瓦斯压力监测系统。在FPGA控制下,井下终端节点采集瓦斯压力数据后先存入NAND Flash中作为备份,然后经路由节点上传至井上瓦斯压力监测平台并实时显示。试验结果表明,系统无需人工干预即可实现对煤层瓦斯压力的多测点全自动实时监测,测量误差小于1%,上位机监测界面可实时显示16个节点的压力变化曲线和6个节点的压力值,对矿井瓦斯压力监测具有重要的实用和推广意义。
At present, the coal mine generally uses the method of manual reading pressure gauge to measure the original gas pressure value of coal seam, which is time-consuming and laborious and has a large reading error.To solve these problems, a downhole monitoring system for coal seam gas pressure is put forward. and carries out the mine gas pressure test through adopting the storage test theory and wireless sensor network technology. Through FPGA, The gas pressure data collected by the downhole terminal node is first stored in NAND Flash as backup, and then uploaded to the gas pressure monitoring platform and displayed in real time through the routing node.The test results show that the system can realize automatic real-time monitoring of multi-measuring points of coal seam gas pressure without manual intervention, and measurement error is less than 1%. The PC monitor interface can display the pressure curve of 16 nodes and the pressure value of 6 nodes in real time. It has important practical and popularizing significance for mine gas pressure monitoring.
