LIKE SO MANY OTHERS , THIS BOOK WAS WRITTEN BECAUSE WE COULDN ’ T FIND ONE LIKE IT . We needed something to hand to all of those people who have come to us asking for “a good book to read on RFID.” When we looked for candidates we found some great books, but most were aimed at electrical engineers or top-level managers, with very little for those of us who are in between. This book is for developers, system and software architects, and project managers, as well as students and professionals in all of the industries impacted by Radio Frequency Identification (RFID) who want to understand how this technology works. As the title suggests, this book is about RFID in general and not just the most recent developments; however, because so much is going on in the Area of RFID for the supply chain and especially the Electronic Product Code (EPC), we have devoted consider- able space to these topics. Regardless of the type of RFID work you may be doing, we think you will find something useful here.

RFID networks are currently recognized as one a research Area of priority. Research activities related to RFID technology have been booming recently. A number of ongoing projects are being funded in Europe, Asia, and North America. According to leading market analysts, the development of the RFID market is projected to increase from approximately $3 billion in 2005 to $25 billion in 2015. Several countries have dedicated innovation programs to support and develop RFID systems and related technologies: the RFID initiative in Taiwan, Ubiquitous Japan and the NSF SBIR program in the USA. The EU has recently advertised its Strategic Research Roadmap concerning the Internet of Things, which first of all refers to the RFID technology before being extended to commu- nicating devices as in M2M (Machine to Machine). In this roadmap, several application domains have been identified:

Radio frequency identification (RFID) and Wireless sensor networks (WSN) are the two key wireless technologies that have diversified applications in the present and the upcoming systems in this Area. RFID is a wireless automated recognition technology which is primarily used to recognize objects or to follow their posi- tion without providing any sign about the physical form of the substance. On the other hand, WSN not only offers information about the state of the substance and environment but also enables multi-hop wireless communications.

I am presenting this novel book on advances and trends in power electronics and motor drives to the professional community with the expectation that it will be given the same wide and enthusiastic acceptance by practicing engineers, R&D professionals, univer- sity professors, and even graduate students that my other books in this Area have. Unlike the traditional books available in the Area of power electronics, this book has a unique presentation format that makes it convenient for group presentations that use Microsoft’s PowerPoint software. In fact, a disk is included that has a PowerPoint file on it that is ready for presentation with the core figures. Presentations can also be organized using just selected portions of the book

CAN (Controller Area Network)是一種串行通信協(xié)議，能夠有效地支持分布式實時控制，具有很高的安全性。它的應用范圍從高速網(wǎng)絡到低成本的多路復用布線。在汽車電子領(lǐng)域，發(fā)動機控制單元、傳感器、防滑系統(tǒng)等均使用CAN連接，比特率可達1mbit /s。與此同時，在汽車車身內(nèi)安裝電子元件，如燈組、電動車窗等，以取代其他需要的線束，也是具有成本效益的。

CAN 是 Controller Area Network 的縮寫，是 ISO 國際標準化的串行通信協(xié)議。CAN總線有兩個ISO國際標準：ISO11898 和 ISO11519。ISO11898 定義了通信速率為 125 kbps～1 Mbps 的高速 CAN 通信標準，屬于閉環(huán)總線，傳輸速率可達1Mbps，總線長度 ≤ 40米。ISO11519 定義了通信速率為 10～125 kbps 的低速 CAN 通信標準，屬于開環(huán)總線，傳輸速率為40kbps時，總線長度可達1000米描述了can通信協(xié)議
