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...

Abstract

The invention discloses a three-dimensional movement sensor node-based gas leakage monitoring system. The system comprises a mesh guide rail arranged above a three-dimensional area to be monitored, aplurality of movement devices with controllers are connected to the mesh guide rail, the movement devices can move along the mesh guide rail under control of the controllers, each one of the movementdevices comprises a pulley, a rope and sensor nodes, the pulley is fixed in the movement device, one end of the rope is fixed to the pulley, the length of the rope can be adjusted by controlling rotation of the pulley, the other end of the rope is connected to the sensor node, each one of the sensor nodes comprises a wireless gas sensor module and a three-dimensional wind vector detection module and each one of the sensor nodes realizes three-dimensional movement and measurement of a gas concentration and a wind vector at any point. The invention provides a gas leakage source positioning method of the system.

Description

technical field [0001] The invention relates to a gas leakage monitoring method, in particular, it can complete the location of gas leakage sources in a three-dimensional complex environment. Background technique [0002] With the rapid development of the chemical industry, more and more toxic and harmful gases are produced, stored and transported. Although these chemical gases serve the development of society and facilitate people's lives, they also threaten people's health, social security and the natural environment. Historically, there have been many large-scale poisonous and harmful gas leakage accidents at home and abroad, causing heavy casualties and property losses. Therefore, once a gas leak occurs, it is of great significance to quickly find and locate the source of the leak. However, due to the turbulent flow in the natural environment, the monitoring of gas leakage, especially the source location, is difficult. [0003] At present, research on gas leakage moni...
