本文針對當前復雜性研究的難點與空白點，提出了供需鏈復雜性的定義；闡述了嫡理論及其與復雜性的相互關系，首次構建了供需鏈系統的通信模型；引入信息論中離散信源與聯合信源的概念，把供需鏈復雜性問題轉化為二元聯合信源的不確定性量度范疇。 -
In this thesis, can bus is used as the system bus, concentrating the research on the feasibility of using redundancy can bus technology in large - scale motor vehicle safety performance detecting & control system. this thesis first gives an overall design of the data collection and control system applied to the front end of a large - scale motor vehicle safety performance detecting & control system. regarding that the bus controller, bus driver and bus transfer medium would fail to function easily, the dual mode cold - redundancy structure is adopted in system to ensure the reliability
本文採用can總線作為系統總線，重點研究冗餘can總線技術應用於大型機動車安全性能測控系統的可行性並進行驗證:首先對基於冗餘can總線的機動車安全性能測控系統的前端數據採集與控制系統進行了總體設計，考慮到總線控制器、總線驅動器和總線介質都是容易出故障的部件，系統採用了二模冷冗餘結構來保障can總線通訊的可靠進行;其次，根據系統需要，設計了基於c8051f021的帶冗餘can總線通道的數據採集與控制模塊，用於採集與處理檢測現場的模擬信號和數字信號，並自行開發了can總線應用層協議以及應用軟體，通過冗餘can總線實現與上位機的可靠通訊;然後，為了驗證冗餘can總線設計方案的可行性，搭建試驗平臺並進行can總線故障切換的試驗;最後對課題的研究工作進行了總結與展望。
