Embodiment Construction
[0023] The core component of the invention is a mobile sensor node structure, involving guide rails, motion devices (including controllers), pulleys, ropes and sensor nodes. The original design of this structure is to solve the problem of difficult installation of sensor nodes in complex environments. In addition, designing sensor nodes in a mobile form can reduce the number of sensor nodes and reduce costs. The sensor node is composed of a wireless gas sensor module and a three-dimensional wind vector detection module, which can reach any point in the three-dimensional space to measure the gas concentration and wind vector of the point under the control of the controller. According to the source localization algorithm of the present invention, the number of sensor nodes is at least four.
[0024] The method for monitoring and locating gas leakage sources in the present invention is based on the idea of dividing tetrahedrons, that is, the area to be monitored is divided into...
