采用嵌入式微处理器LPC2129作为控制单位,设计了煤矿瓦斯浓度和风速监测节点,各节点通过CAN总线与监控主机连接进行通信,对各节点监测区域的瓦斯浓度数据分析后,主机向风机节点发送控制指令,调节风机的输出功率。该系统不仅监测风机出风口附近的瓦斯浓度和风速,而且做到了对整个矿井内各个区域实时掌握,以便对风机的工作状态做出及时的调整,达到安全生产和节能的目的。
The embedded microprocessor LPC2129 is used as the control unit to design the gas concentration and wind speed monitoring nodes in coal mine. Each node communicates with the monitoring host via CAN bus. After analyzing the gas concentration data in the monitoring area of each node, the host sends control to the wind turbine node Command, adjust the fan output power. The system not only monitors the gas concentration and wind speed near the air outlet of the fan, but also realizes the real-time mastery of the various regions in the entire mine so that the working status of the fan can be adjusted in time to achieve safety production and energy saving.
