Remote smart gas control system mainly consists of three parts: the hardware part of data acquisition, the network transmission part and the software processing part. Collecting the data acquisition module in part collect the data from gas meter by a certain communication protocol method; Data is based on GPRS/CDMA/3G network, and sent that to Data Monitoring Center; Data Center can use computer communication, information management and database system to real-time monitoring the gas meter’s working status on customer sides. This system not only can collect real-time data (including the flow, temperature, pressure and other information), but also can carry out real-time information monitoring, data analysis and statistics. It also can remote charge and control gas meter. It can adjust price for multi-tier pricing mechanism. And it also can alarm when the smart gas meter has abnormal information.The topology diagram of GPRS/CDMA remote smart gas control system is as the follows:
