摘要： 针对现在中低端汽车中使用的具有固定频率无钥匙进入系统容易被干扰和破解,导致汽车防盗系统损坏甚至汽车丢失的问题,并为了保证无钥匙进入系统可以长时间使用以及未来可能的系统扩展升级,利用基于ARM9的S3C2410微处理器以及具有载波频率调制功能的射频收发芯片nRF905设计了一款新式的低功耗高可靠性的无钥匙进入系统.该系统利用跳频通信技术使得信息在通信过程中不会被干扰或拦截,增强了系统的可靠性；采用合理的电源管理模块,极大地降低了系统功耗.试验表明该无钥匙进入系统能够很好地满足实际应用要求.

Abstract: In order to solve the problem that the the PKE(passive keyless enter) with a fixed-frequency used in mid-and-low end cars was interfered and broken easily, which led to the damage of anti-theft system and even the loss of cars, and in order to ensure the PKE can be used long and be expanded and upgraded in the future, a new, low power consumption and high reliability PKE was designed with the S3C2410 microprocessor which is based on ARM9 and the RF transceiver chip nRF905 which has the function of frequency modulation. As frequency-hopping communication technology was used in the system, the information would not be disturbed or blocked in the communication process, which increased the reliability of the system. With reasonable power-management module, the system power consumption was greatly reduced. Test shows that the new PKE can well meet the practical application.
