Remote Monitoring and Warning Technology for Combustible Gas in Large Scale and Multiple Regions

To establish a unified platform for combustible gas monitoring and warning in large scale and multiple regions, the technology of wireless ad-hoc network and general packet radio service (GPRS) were used to the acquisition node and the convergence transmission node of combustible gas monitoring and warning. Meanwhile, a cloud management platform in a server were built by web and database technology. The algorithm of temperature and humidity compensation combined with multistage alarm strategy and data encryption made the system more accurate, secure and intelligent. The system has been used in residential area for combustible gas monitoring and warning. The management department could also make immediate decision and analysis data in a long term through the cloud management platform. Application test shows that both the packet loss rate and the time of receiving warning information are completely qualified.
