摘　　要：设计了一种基于无线Mesh网络的瓦斯监测节点,详细介绍了节点电池供电电路、瓦斯检测电路、报警电路、显示电路、光控电路、无线组网模块6个部分硬件电路设计,以及各部分电路功耗及低功耗工作机制。模拟测试表明,该节点实现了无线自组网及低功耗运行,能够保证瓦斯监测节点在不换电池的情况下工作7 d以上。A gas monitoring node based on wireless Mesh network is designed. Six parts of the hardware circuit is presented in detail,including the node battery power supply circuit,gas detection circuit,alarm circuit,display circuit,light control circuit,wireless network module,and the power consumption and work mechanism of all parts of the hardware circuit are presented in detail too. The simulation results show that the node realizes the wireless ad hoc network and low power consumption,and can ensure the gas monitoring node to work more than 7 days without changing the battery.
