I was pleasantly surprised when in November 2005 a message arrived from Wayne Wheeler, the new computer science editor of Springer Verlag, notifying me that he in tends to qualify this book as a Springer major reference work (MRW), thereby releasing past restrictions on page counts, freeing me from the constraint of having to compress my style, and making it possible to include important and interesting data compression methods that were either ignored or mentioned in passing in previous editions.

as a message came into prominence with the publication in 1948 of an influential paper by Claude Shannon, "A Mathematical Theory of Communication." This paper provides the foundations of information theory and endows the word information not only with a technical meaning but also a measure. If the sending device is equally likely to send any one of a set of N messages, then the preferred measure of "the information produced when one message is chosen from the set" is the base two logarithm of N (This measure is called self-information). In this paper, Shannon cont

電動汽車TTCAN總線技術(shù)研究.rar

TTCAN協(xié)議在CAN協(xié)議基礎(chǔ)之上，將事件觸發(fā)機制與實時性更高的時間觸發(fā)機制相結(jié)合，提高了網(wǎng)絡(luò)實時性，滿足對安全性要求苛刻的實時系統(tǒng)以及總線日益增長的信息負載的需求；同時，CAN總線技術(shù)的基礎(chǔ)為TTCAN總線技術(shù)研究奠定了很好的軟硬件支持條件。論文首先介紹了TTCAN協(xié)議的通訊原理、軟硬件環(huán)境的建立和總線網(wǎng)絡(luò)性能的測試方法。按照ISO11898－4標(biāo)準(zhǔn)的要求，在自主研發(fā)的CAN總線實時仿真系統(tǒng)上結(jié)合軟件編程能夠?qū)崿F(xiàn)TTCAN協(xié)議的時間觸發(fā)通訊功能，使整個系統(tǒng)成為具有時間觸發(fā)功能的TTCAN總線通訊網(wǎng)絡(luò)，得到網(wǎng)絡(luò)要采用TTCAN協(xié)議通訊時各ECU必須具備穩(wěn)定可靠的本地時鐘和相應(yīng)的時鐘同步和計數(shù)機制的結(jié)論。結(jié)合混合動力電動汽車動力系統(tǒng)對采用TTCAN協(xié)議通訊時的網(wǎng)絡(luò)性能進行了測試和分析，結(jié)果表明，TTCAN網(wǎng)絡(luò)中周期型消息的實時性不受網(wǎng)絡(luò)中其他消息的影響，時間觸發(fā)通訊方式和系統(tǒng)矩陣的調(diào)度安排在一定程度上減少了總線上消息間的沖突，提高了網(wǎng)絡(luò)實時性和總線帶寬利用率。對比分析同等條件下TTCAN總線網(wǎng)絡(luò)和CAN總線網(wǎng)絡(luò)的性能，TTCAN協(xié)議能夠保證網(wǎng)絡(luò)總線在高峰值負載的情況下網(wǎng)絡(luò)的實時性。研究了對TTCAN總線網(wǎng)絡(luò)中time master（時間主節(jié)點）和reference message（參考消息）進行故障診斷和容錯的方法，通過實驗驗證了采用冗余的方式能夠保證當(dāng)前時間意義上的主節(jié)點和參考消息故障情況下整個網(wǎng)絡(luò)的性能不受影響，提高故障情況下網(wǎng)絡(luò)的可靠性。
