【摘要】：电力线通信技术作为一种新型通信技术,具有无需重新布线、分布范围广的优点,因此,它成为国内外研究的热点。远程抄表作为低压电力线通信技术的一个应用,是智能电网的重要组成部分。目前,基于低压电力线通信技术的远程抄表系统主要采用窄带电力线通信技术,这种抄表系统具有通信速率低、扩展性差和数据不能共享等缺点。因此,提出了基于宽带电力线通信技术的远程抄表系统,并对整个系统进行了架构设计。该系统由远程服务器、家庭网关和电表服务器构成。本论文主要进行家庭网关的设计与开发,家庭网关由家庭路由控制器和宽带电力线通信调制解调器构成。在开发中,硬件开发平台选用飞思卡尔单片机开发板MCF52233DEMO,嵌入式操作系统选用具有移植简单、实时性强、源码开放等优点的嵌入式操作系统μC/OS-II。先将μC/OS-II移植在MCF52233DEMO上来构建软件开发平台,然后完成MCF52233DEMO中GPIO口、异步串行通信接口和以太网接口的驱动程序设计。在自主实现TCP/IP协议栈中部分协议基础上,完成了家庭路由控制器中嵌入式控制终端的设计与开发。该嵌入式网关作为新型家庭网关不但具有常见的网络管理功能,而且能通过网关的网络接口和串口实现对设备的控制。在基于低压电力线通信技术的智能家庭和智能电网等领域中,既可以用作网络管理器,又可以用作控制终端。
[Abstract]:As a new type of communication technology, power line communication technology has the advantages of no rewiring and wide distribution, so it has become a research hotspot at home and abroad. At present, the remote meter reading system based on low voltage power line communication technology mainly adopts narrow band power line communication technology, this kind of meter reading system has low communication rate. Therefore, a remote meter reading system based on broadband power line communication technology is proposed, and the whole system is designed. The system is composed of remote server, home gateway and ammeter server. The home gateway is composed of a home routing controller and a broadband power line communication modem. The hardware development platform is MCF52233DEMO.The embedded operating system 渭 C / OS-II, which has the advantages of simple transplantation, high real-time performance and open source code, is used to build the software development platform by transplanting 渭 C / OS-II onto MCF52233DEMO. Then, the driver design of GPIO port, asynchronous serial communication interface and Ethernet interface in MCF52233DEMO is completed, and the design and development of embedded control terminal in home routing controller is completed on the basis of implementing some protocols in TCP/IP protocol stack. As a new type of home gateway, the embedded gateway not only has common network management functions, In the field of intelligent home and smart grid based on low-voltage power line communication technology, it can be used not only as network manager but also as control terminal.
