The traditional method has the problems of low alarm efficiency and high energy consumption, and puts forward the design of the Luqiao tunnel pressure alarm sensor node. According to the overall architecture of sensor nodes, the hardware design of sensor node, and the pressure sensor, MCU and wireless alarm sensing unit and the interface circuit module driver analysis; information interaction based on embedded bottom construction, communication protocol, collecting data through wireless sensor, and the deployment of sensor nodes. The experimental results show that the design method takes full account of data acquisition, and has the advantages of high alarm efficiency and small energy consumption, which can realize the safe operation of Luqiao tunnel.
