摘要
研制的智能钥匙系统将滚动码技术与无线通信技术相结合,利用单片机PIC16F639和无线接收模块TDA5201设计了一种可以进行高、低频双向通信的汽车交互式无钥匙门禁系统;该系统功耗低、收发距离远、可靠性及安全性高,给出具体的软、硬件设计,并对设计中的关键技术进行详细的描述;系统无需人为干预就可自动执行对用户的身份识别,符合未来汽车的智能安全的发展方向,且稍加改动即可应用于汽车轮胎测压和汽车防盗等方面,具有极佳的市场前景和巨大的潜在效益。
A novel intelligent key system is designed by means of combination of KEELOQ technology and wireless-communication technology in this paper. By using a PIC16F639 MCU and TDA5201 wireless receiver module, the high-low-frequency two-way commu- nication automobile keyless entry system is developed. The test results show that this system has many advantages such as low power, long communication distance, high reliability and high security. This paper gives the design of hardware and software. Moreover the key technologies in design are analyzed in detail. This system can recognize user identity without keystroke, in line with the direction of intelligent and security development of the vehicle, but also can make up automobile tire pressure monitoring system or vehicle anti-theft system etc, which has excellent market prospects and huge potential benefits.
