【摘要】：建立高速、双向、实时、集成的通信系统是实现智能电网的基础。智能电网在通信技术领域主要关注两个方面。其一是开放的通信架构,形成“即插即用”的环境,使电网元件之间能够进行网络化通信;其二是统一的技术标准,能使所有的传感器、智能电子设备以及应用系统之间实现无缝通信。而集中器是整个智能电网的抄表系统的关键,起着承上启下的作用,所以是研究的重点。本文分析了国内外抄表系统以及集中器研究现状,发现市场上存在的集中器都是基于IPv4的。但是IPv4地址将被耗尽无法提供更多的地址,而IPv6拥有无限的地址空间,能够实现电网中每个设备都能有一个IP地址,并且传输效率高、速度快、网络安全性高;具有无状态地址自动分配的特点,可以支持新增设备迅速连接到网络上,真正实现即插即用的功能。本文详细介绍了IPv6智能电网集中器的设计过程,包括集中器系统设计、集中器硬件设计以及集中器的软件设计。集中器采用的是基于ARM9的内核S3C2440处理器的mini2440开发板,系统设计主要是介绍了主机、集中器、路由器、智能电表之间的连接,详细介绍了各部分的功能以及是如何完成通信,关键介绍了376.1、376.2、IPv6、645之间的协议转换;硬件设计主要是进行了IPv6模块设计、GPRS模块设计、Flash存储器设计、SDARM存储设计以及电源等设计;软件设计主要包括Linux内核移植、U-boot移植、交叉环境的建立、协议转换程序设计等。基于IPv6智能电网集中器可以高效稳定的工作,实现每个电表一个IP地址,网络安全比IPv4高而且传输效率更快。
[Abstract]:The establishment of high-speed, bidirectional, real-time and integrated communication system is the basis of smart grid. Smart grid mainly pays attention to two aspects in the field of communication technology. One is the open communication architecture, which forms a "plug and play" environment, which enables the network communication between power grid components, and the other is a unified technical standard, which enables seamless communication between all sensors, intelligent electronic devices and application systems. Concentrator is the key to the meter reading system of the whole smart grid, which plays the role of connecting the above and the following, so it is the focus of research. In this paper, the research status of meter reading system and concentrator at home and abroad is analyzed, and it is found that the concentrator in the market is based on IPv4. However, the IPv4 address will be exhausted and can not provide more addresses, and IPv6 has unlimited address space, which can realize that every device in the power grid can have a IP address, and the transmission efficiency is high, the speed is fast, and the network security is high. It has the characteristics of automatic address allocation, which can support the new devices to connect to the network quickly and realize the function of plug and play. In this paper, the design process of IPv6 smart grid concentrator is introduced in detail, including concentrator system design, concentrator hardware design and concentrator software design. The concentrator adopts the mini2440 development board of kernel S3C2440 processor based on ARM9. The system design mainly introduces the connection between host computer, concentrator, router and intelligent meter, introduces in detail the functions of each part and how to complete the communication, and key introduces the protocol conversion between 376.13762 and IPv4 6645. The hardware design mainly includes IPv6 module design, GPRS module design, Flash memory design, SDARM storage design and power supply design, and the software design mainly includes Linux kernel transplantation, U-boot transplantation, cross environment establishment, protocol conversion program design and so on. The smart grid concentrator based on IPv6 can work efficiently and stably, and realize one IP address per meter. The network security is higher than that of IPv4 and the transmission efficiency is faster.
