摘要
针对目前无线通信技术在电力监控系统中的应用,研究了一种通过GPRS网络将电力监控终端接入互联网的技术方案。该方案利用GPRS无线模块与GPRS网络间的无线信道作为物理层接口,在此之上通过PPP协议实现数据链路层,最后采用uIP软件协议栈实现精简的TCP/IP协议作为网络层和传输层。在应用层采用了自定义规约。由于协议各层次都是纯软件实现,因此本方案具有成本低廉、配置灵活的特点,并且在现场使用,效果良好。
Due to the application of wireless communication technology in the electric power monitoring system, the method that power monitoring unit accessing Internet based on GPRS is presented. The wireless channels between the GPRS wireless module and GPRS network are as the interface of physical layer, the PPP is used to data link layer. Also the uIP protocol instead of the complicated TCP/IP is used to implement the network layer and the transport layer. The user-defined protocol is used to the application layer. Since the protocols are implemented by software, it is low cost and flexible configuration. And the power monitoring unit is used in good working order.
