The performance test virtual system of power line carrier based on lonworks locale control technology. the syetem is structure of modularity, it can be used to test all kinds of parameters of network performance according to your different requirements. in the lonmaker operation system and distributed database management system, the software of the system adopts object oriented programme. it can be run in windows 2000 system credibly
電力線載波通信網路性能虛擬測試儀基於lonworks現場總線控制技術,它採用了模塊化結構,可根據不同的測試需求,構成不同的測試系統。本虛擬測試儀的上位機軟體是在lonmaker操作系統和分散式數據庫管理系統microsoftsqlserver下採用的面向對象的編程方法開發完成的,可以在windows2000操作系統下可靠運行。Then test the time delay bandwidth and probability of error - code of power line carrier conmmunication network by plca - 22 protocol analyse apparatus to testify the validity of the system. at last i compare the results tested by the performance test virtual system and plca - 22 apparatus respectively, and analysis the virtue and shortage of the performance test virtual system, then bring forward the means to improve
然後使用plca - 22協議分析儀對此電力線載波網路的延時、帶寬、誤碼率進行測試,以驗證本電力線載波通信性能虛擬測試儀設計的正確性。最後對比電力線載波通信網路性能虛擬測試儀和plca - 22測試出的結果,分析電力線載波通信網路性能虛擬測試儀的優點和不足,提出了改進的方法。The performance test is to find out the factor of effecting the networks performance. performance analyse is the base and precondition of how to optimize the network performance. in the power line carrier network, it ’ s very far - ranging to test network performance by power line communication analysis apparatus plca - 22, protocol analysis apparatus lonmanager and lonscanner. but they are very expensive and can ’ t be popularized. so because of it, i design a performance test virtual system of power line carrier communication network
性能測試的目的在於找出影響網路性能的因素,從而得到提高網路性能的方法,因此性能測試是網路性能優化的基礎和前提。在電力線載波網路中,最為廣泛的方法是使用電力線通信分析儀plca - 22 , lonmanager協議分析儀和lonscanner協議分析儀對網路的性能進行測試。但是它們都非常的昂貴,不能普及,本文針對此,設計了電力線載波通信網路的網路性能虛擬測試儀。First the dissertation analyzes and compares the actuality of the performance of the power line carrier network, then put forward the principle of the test system, configuration of the hardware and design of the software of the system. so i analyze the theory of the test system by testing the time delay, and analyze the factor which effect the time delay. then narrate how to test the bandwidth and probability of error - code briefly
論文首先對電力線載波網路性能研究的現狀進行了分析和比較,然後提出本虛擬測試儀的實現原理,硬體的配製以及軟體的設計,接著通過詳細的延時測試說明此虛擬測試儀的運作原理,並分析影響延時的因素。還簡要地說明如何使用此虛擬測試儀對網路帶寬和誤碼率進行測試。分享友人
