实时网络交互燃气计量系统的集中器设计与实现

The Design and Implementation of the Concentrator on the Interactive Real-Time NetWork Gas measurement System

本文围绕实时网络交互燃气计量系统的集中器进行研究,提出技术方案并加以实现。集中器下行通讯接口桥接PLC网络或HFC的同轴部分,上行通讯接口桥接GPRS模块或HFC的光纤部分。本文基于X86体系的WindowsCE操作系统和ARM9嵌入式平台的uClinux操作系统,对使用PLC网络接口和GPRS模块网络接口方式下的集中器的嵌入式软件进行设计和实现,解决了系统销售服务器与计量终端之间的双向通讯和规约转换。

This article focuses on the Concentrator on the Interactive Real -Time NetWork Gas measurement System to explore research and technical programs and to achieve which is a design of the Concentrator bridging communication interface for downlink PLC network or HFC coaxial part of uplink communications interface bridging GPRS module or HFC fiber - optic parts. Based on the X86 system and the Windows CE operating system platform ARM9 uClinux embedded operating system, the use of PLC Network Interface and GPRS network interface module under way on embedded software for the design and realization of the system to resolve the two -way communications, the converter and the Statute between the sale server and the gas metering terminal server.
