【摘要】：電力載波通信(Power Line Carrier Communication,PLC)是指利用電力線作為通信傳輸信道的一種通信技術(shù)。電力線路本身可靠性高且通達(dá)各地,將其用作通信線路則具有得天獨厚的優(yōu)勢。隨著“堅強智能電網(wǎng)”在“十二五”計劃期間逐步推廣,更實時的業(yè)務(wù)需求開始出現(xiàn),對電力載波通信網(wǎng)絡(luò)可靠性、實時性有了更高的要求。因此為了提高網(wǎng)絡(luò)實時性而優(yōu)化任務(wù)調(diào)度策略具有較高的應(yīng)用價值。本文分析了AMI系統(tǒng)中集中器頻繁執(zhí)行的眾多任務(wù),將主要任務(wù)可以分為兩種類型,即單節(jié)點通信任務(wù)和全網(wǎng)數(shù)據(jù)收集任務(wù)。單節(jié)點通信任務(wù)通常采用指定中繼或采用路由算法尋路來完成通信,相關(guān)路由算法的研究也較多。全網(wǎng)載波子節(jié)點數(shù)據(jù)收集任務(wù)通常采用單節(jié)點輪詢收集的調(diào)度機制,即通過反復(fù)執(zhí)行多次單點收集來完成任務(wù)。這種單點輪詢的調(diào)度機制簡單易于操作,但忽視了節(jié)點間的關(guān)系,任務(wù)執(zhí)行時間也較長,且隨著網(wǎng)絡(luò)規(guī)模的擴(kuò)大,耗時也更多,大大降低了電力載波通信系統(tǒng)的實時性。本文從單節(jié)點通信任務(wù)的路由算法入手,基于分簇物理拓?fù)浣Y(jié)構(gòu),為完成域管理節(jié)點(Domain Master,DM)和子節(jié)點之間的通信任務(wù),研究一種最優(yōu)位置轉(zhuǎn)發(fā)路由算法。在此路由算法的基礎(chǔ)上,提出了單分支收集算法(Single Branch Collection,SBC)和單簇收集算法(Single Cluster Collection,SCC),并提出了適應(yīng)于全網(wǎng)數(shù)據(jù)收集任務(wù)的單分支收集為主、單簇和單點補充收集為輔的調(diào)度策略。通過Matlab仿真結(jié)果比較,單節(jié)點通信任務(wù)和全網(wǎng)收集任務(wù)的總的報文發(fā)送次數(shù)得到了縮減,提高了任務(wù)執(zhí)行的時間性能。另外,采用高速載波芯片搭建了電力載波通信環(huán)境,設(shè)計了通信協(xié)議并實現(xiàn)了優(yōu)化后的調(diào)度策略,進(jìn)一步驗證了優(yōu)化后的調(diào)度策略在實際載波環(huán)境中良好的時間性能。
[Abstract]:Power Line Carrier Communication (PLC) is a communication technology which uses power line as communication channel. The power line itself has high reliability and access to various places, and it has a unique advantage as a communication line. With the gradual promotion of "strong smart grid" in the 12th Five-Year Plan period, more real-time service requirements begin to appear, which has higher requirements for the reliability and real-time performance of power carrier communication network. Therefore, to improve the real-time performance of the network and optimize the task scheduling strategy has a higher application value. This paper analyzes many tasks frequently performed by concentrators in AMI system. The main tasks can be divided into two types: single node communication task and whole network data collection task. Single node communication tasks usually use specific relay or routing algorithm to complete the communication. The data collection task of carrier subnode in the whole network usually adopts the scheduling mechanism of single node polling collection, that is, the task is completed by repeated single point collection. The scheduling mechanism of single point polling is simple and easy to operate, but the relationship between nodes is ignored, the task execution time is longer, and with the expansion of network scale, the time consuming is more and more, which greatly reduces the real-time performance of power carrier communication system. Starting with the routing algorithm of single node communication task, based on the cluster physical topology, this paper studies an optimal location forwarding routing algorithm in order to complete the communication task between domain management node and sub-nodes. Based on this routing algorithm, a single Branch collection algorithm (single Branch collection) and a single Cluster collection algorithm (single Cluster collection) are proposed, and a scheduling strategy is proposed, which is based on single branch collection, supplemented by single cluster and single point supplementary collection, which is suitable for the task of data collection in the whole network. Compared with the simulation results of Matlab, the total number of packets sent between the single node communication task and the whole network collection task is reduced, and the time performance of task execution is improved. In addition, the power carrier communication environment is built with high speed carrier chip, the communication protocol is designed and the optimized scheduling strategy is implemented, which further verifies the good time performance of the optimized scheduling strategy in the actual carrier environment.
