摘要
借鉴物联网技术应用中EPC-global体系的构建方式,设计开发了由用户计量表具PGM、固定式和移动式燃气计量数据采集集中器GMDC、表具ID解析服务器OMNS及相应的通讯规约构成的燃气物联网应用系统,该系统可以解决城市管道燃气终端用户用气计量数据采集问题。其中,GMDC类似于Savant,是系统中的关键组件,文中详细介绍了GMDC的构成和工作原理。
The IOT-based urban pipeline gas system which is composed of pipeline gas meter （PGM）, gas metering data concentrator （GMDC）, object meter name server （OMNS） and corresponding communication protocol is designed and developed by using the EPC-global system for reference to measure how much of gas terminal users of the system use and acquire data. Among the modules, GMDC is the key component which is similar to the Savant of EPC-global system. The structure and operating principle of GMDC is introduced in detail.
