智能远程抄表系统集中控制器及通信协议设计

针对目前远程抄表技术落后、通信协议互操作性差、网络运行成本高等问题,为满足智能电网环境下对智能抄表提出的要求,本文提出了一种智能型、基于GSM和ZigBee双层结构网络的架构,并针对抄表系统的数据特点设计了远程抄表系统的通信协议;为保证通信链路的可靠性,设计出呼叫,应答,再通信的串口通信方案。最后,在实验条件下对所设计的系统进行了测试,测试结果表明,系统可靠性高、成本低廉、组网简单、抄表速度适中,基本达到了设计要求。

Design of Centralized Controller and Communication Protocol used in Smart Remote Meter Reading System

Considering the fact of obsolete remote meter reading technology, poor communication protocol interoperability, high network operation costs, in order to meet the requirements of smart meter reading in smart power grid, a kind of new two level network framework based on GSM ZigBee is proposed in which the communication protocol of remote meter reading system is designed. To ensure the reliability of communication link, the serial port communication solution which include the call, response, communication process. In the end of this paper, the solution is tested in laboratory. Test result shows that the system can be characterized as high reliability, low cost, simple network scheme, and moderate meter reading speed. The solution in this paper can meet the design requirements.
