WSN based Gas Leakage Detecting and Locating System for Petrochemical Industry

This paper develops a gas leakage detecting and locating system for the production safety in Petrochemical Industry based on Wireless Sensor Networks (WSN). It can collect the data of monitoring sites wirelessly and sent to the computer to update values in the location software. Consequently, it can give a real-time detective of the potential risk area, collect the data of a leak accident and locate the leakage point. However the former systems can not react in time, even cannot obtain data from an accident and locate accurately. The paper has three parts, first gives the overall system design, and then provides the approaches on both hardware and software to achieve it.
