碩士 === 國立勤益科技大學 === 工業工程與管理系 === 99 === RFID signals to prevent collisions and to enhance the RFID reader (Reader) to read electronic tags (Tag) efficiency, this study proposes a new algorithm idea is for the passive electronic tag (Tag) signal collision, the combined Meridian concept RFID signals to prevent collisions. To the human body, blood circulation is not good it will cause pain, but pain is usually the place, blocking the formation of almost all the gas pain, but this phenomenon with the RFID reader (Reader) read numerous electronic tag (Tag) When, at the same time, Reader to receive numerous signals, the signal blocking caused by failure to read or read data is not complete, which will reduce the reading and, therefore, this study of traditional Chinese medicine meridian theory, developed a set of algorithm, we named it as the Chinese Meridian Theory Algorithm (CMTA), and with other methods of simulation experiments, subjects in this study, a total of four methods, respectively, Binary Tree Algorithm (BTA), Bit competed calculus Act (BCA), Pure-Aloha algorithm (PAA), Chinese Meridian Theory algorithm (CMTA), we limit these four methods in the same environment for simulation, the results show Tag reads 10000, this study proposed CMTA takes seconds to 1172.562 s, followed by the BCA takes seconds to 1609.4 s, followed by PAA takes seconds to 1993.34 s, and finally the BTA takes seconds to 2754.688 s, we can see that CMTA is better than the BCA, more than PAA and BTA.
