摘要
汽车遥控门禁系统(RKE-remote keyless entry system)是一种应用于车辆的防盗技术。它可以用来远程遥控车门的上锁和解锁请求。该系统通过钥匙端发送一串特殊编码的数据,汽车防盗系统在接收到该数据后,进行解码运算来判断该数据的有效性,之后执行上锁或解锁的请求。由于无线干扰问题的存在,当钥匙和汽车间的通讯时间越长,受干扰的几率就越大。为了避免经常出错,对整个发送方式做一改进,以尽量减少受干扰的情况发生。
A Remote Keyless Entry System is an anti-theft technology for vehicles. It can be used to remote control door lock and unlock requests. The system sends a stream through a specially coded data, the receiver in car gets the data and decodes with encrypt algorithm. After decrypting the key information, the vehicle performs lock or unlock request. As wireless interference problems, the longer the communication spends between the key and the vehicle, the greater the chance of interference. In order to avoid these mistakes, this paper tries to improve the method for key fob＇s button strategy.
