摘要
电动自行车在70-80年代经历了几次大起大落以后，充分运用当今新技术、新材料，尤其采用集成电路、新型电机、蓄电池等，提高了电动自行车质量，使其可靠性、安全性、灵活性得到了很大提高，到90年代初又再度形成热点，顺应了21世纪世界环保的潮流(它又称为绿色代步工具)。射频识别技术（Radio Frequency Identification，缩写RFID），射频识别技术是20世纪90年代开始兴起的一种自动识别技术，射频识别技术是一项利用射频信号通过空间耦合(交变磁场或电磁场)实现无接触信息传递并通过所传递的信息达到识别目的的技术。本研究运采用RFID技术，对电动自行车的实时时速、蓄电池电压、驱动档位、里程等数据进行无线识别传输，传输距离能达到2米以上，多台自行车上都使用无线里程计时，不会互相串扰。将进一步革新电动自行车的技术。提高电动自行车在日常生活中的价值。关键字：RFID；电动自行车；里程计；单片机；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.
