摘要
電動自行車在70-80年代經歷了幾次大起大落以后，充分運用當今新技術、新材料，尤其采用集成電路、新型電機、蓄電池等，提高了電動自行車質量，使其可靠性、安全性、靈活性得到了很大提高，到90年代初又再度形成熱點，順應了21世紀世界環保的潮流(它又稱為綠色代步工具)。射頻識別技術（Radio Frequency Identification，縮寫RFID），射頻識別技術是20世紀90年代開始興起的一種自動識別技術，射頻識別技術是一項利用射頻信號通過空間耦合(交變磁場或電磁場)實現無接觸信息傳遞并通過所傳遞的信息達到識別目的的技術。本研究運采用RFID技術，對電動自行車的實時時速、蓄電池電壓、驅動檔位、里程等數據進行無線識別傳輸，傳輸距離能達到2米以上，多臺自行車上都使用無線里程計時，不會互相串擾。將進一步革新電動自行車的技術。提高電動自行車在日常生活中的價值。關鍵字：RFID；電動自行車；里程計；單片機；CC2500
Abstract
Electric bicycle in the 70-80 years experienced several ups and downs after the full use of today, new technologies, new materials, in particular, use of integrated circuits, new motor, batteries, etc. to improve the quality of electric bicycles to the reliability, security, flexibility has been greatly improved, to the early 90s and again in the formation of hot spots, conforms to the trend of environmental protection in the 21st century (it is called green travel tools). Radio frequency identification technology (Radio Frequency Identification, abbreviation RFID), radio frequency identification technology is the 20th century, the rise of the 90s an automatic identification technology, radio frequency identification technology is the use of a radio frequency signal through space coupling (alternating magnetic field or EMF) free access to information transmission, and pass the message to identify the purpose of technology. This study uses RFID technology, transportation, real-time speed limit for electric bicycles, battery voltage, drive gear, mileage and other data, RFID transmission, transmission distance can reach 2 meters or more, more than one bicycle use wireless mileage timing, not mutually crosstalk. Electric bicycles will be further innovation technology. Improve the electric bicycle in daily life value.
