Gas Leakage Monitoring with Mobile Wireless Sensor Networks

Abstract

In this paper, a real-time and early warning gas leakage monitoring system has been developed for large-scale region based on Mobile Wireless Sensor Networks (MWSNs). The system consists two parts: sensor terminal and center server. A sensor terminal includes TDLAS gas sensor which has remarkably high accuracy and reasonable size, microcontroller, Global Position System (GPS) receiver module, General Packet Radio Service (GPRS) module and power module. The center server is developed to receive, process and store the data. A real-time monitoring cloud platform is developed to display real-time data. A mobile wireless sensors networks, which consists of mobile sensor terminals and stationary sensor terminals, enable a large-region leakage monitoring. Experiments are carried out to valid the system. The results show that the real-time and early warning gas leakage monitoring system developed in this paper is reliable and practice.
