【摘要】：建立高速、雙向、實(shí)時(shí)、集成的通信系統(tǒng)是實(shí)現(xiàn)智能電網(wǎng)的基礎(chǔ)。智能電網(wǎng)在通信技術(shù)領(lǐng)域主要關(guān)注兩個(gè)方面。其一是開放的通信架構(gòu),形成“即插即用”的環(huán)境,使電網(wǎng)元件之間能夠進(jìn)行網(wǎng)絡(luò)化通信;其二是統(tǒng)一的技術(shù)標(biāo)準(zhǔn),能使所有的傳感器、智能電子設(shè)備以及應(yīng)用系統(tǒng)之間實(shí)現(xiàn)無縫通信。而集中器是整個(gè)智能電網(wǎng)的抄表系統(tǒng)的關(guān)鍵,起著承上啟下的作用,所以是研究的重點(diǎn)。本文分析了國內(nèi)外抄表系統(tǒng)以及集中器研究現(xiàn)狀,發(fā)現(xiàn)市場上存在的集中器都是基于IPv4的。但是IPv4地址將被耗盡無法提供更多的地址,而IPv6擁有無限的地址空間,能夠?qū)崿F(xiàn)電網(wǎng)中每個(gè)設(shè)備都能有一個(gè)IP地址,并且傳輸效率高、速度快、網(wǎng)絡(luò)安全性高;具有無狀態(tài)地址自動(dòng)分配的特點(diǎn),可以支持新增設(shè)備迅速連接到網(wǎng)絡(luò)上,真正實(shí)現(xiàn)即插即用的功能。本文詳細(xì)介紹了IPv6智能電網(wǎng)集中器的設(shè)計(jì)過程,包括集中器系統(tǒng)設(shè)計(jì)、集中器硬件設(shè)計(jì)以及集中器的軟件設(shè)計(jì)。集中器采用的是基于ARM9的內(nèi)核S3C2440處理器的mini2440開發(fā)板,系統(tǒng)設(shè)計(jì)主要是介紹了主機(jī)、集中器、路由器、智能電表之間的連接,詳細(xì)介紹了各部分的功能以及是如何完成通信,關(guān)鍵介紹了376.1、376.2、IPv6、645之間的協(xié)議轉(zhuǎn)換;硬件設(shè)計(jì)主要是進(jìn)行了IPv6模塊設(shè)計(jì)、GPRS模塊設(shè)計(jì)、Flash存儲(chǔ)器設(shè)計(jì)、SDARM存儲(chǔ)設(shè)計(jì)以及電源等設(shè)計(jì);軟件設(shè)計(jì)主要包括Linux內(nèi)核移植、U-boot移植、交叉環(huán)境的建立、協(xié)議轉(zhuǎn)換程序設(shè)計(jì)等�；贗Pv6智能電網(wǎng)集中器可以高效穩(wěn)定的工作,實(shí)現(xiàn)每個(gè)電表一個(gè)IP地址,網(wǎng)絡(luò)安全比IPv4高而且傳輸效率更快。
[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.
