摘要: 针对传统瓦斯抽放监测系统由于监测参数多而存在安装传感器多、铺设电缆多、安装维护不便等问题，设计了一种新型矿用多参数气体流量传感器。该传感器可测量管径为80～1 000 mm的管道内流速为0.3～30 m/s的气体流量，只需在管道上取一个安装孔，传感器接一根四芯监控电缆就可通过RS485将管道流量、温度和压力信号上传到传输分站。工业性试验结果表明，该传感器量程比大，稳定性好，减少了瓦斯抽放监测系统前期调研、施工和维护等工作量，具有较强的实用性。Abstract: In order to solve problem that traditional gas drainage monitoring system needs many sensors, cables and has inconvenient installation and maintenance because of too many monitored parameters, the paper designed a new kind of mine-used multi-parameter gas flow sensor. The sensor can measure gas flow with flow rate between 0.3 m/s to 30 m/s in pipeline with diameter between 80 mm to 1 000 mm. The sensor only needs a mounting hole for installation, and uses a four-core cable to transfer signals of flow, temperature and pressure to transmission substation by RS485. Industrial test results show that the sensor has high range ratio, good stability and practicability, and can reduce workload of preliminary research, construction and maintenance of gas drainage monitoring system.
