摘要随着汽车数量的不断增多，车辆被盗的数量也逐年上升，担心车辆被盗，成为每一位汽车用户关心的问题。

因此，研制出高性能的汽车防盗报警系统具有重要的应用价值。

目前，滚动码加密技术和无线遥控技术已经有了长足的发展，将该技术融入汽车防盗系统，是汽车防盗系统新的发展方向之一。

本课题设计一种可以远程遥控汽车车门的开关。

这种设计通过钥匙上发出的信号，来控制车门锁上的电动机，车门就可以打开或者关闭。

要实现该功能，采用了HCS301滚动码编码器作为钥匙发射模块核心，且配对解码芯片TDH6301，从而设计了一种可靠性和安全性较高的汽车车门控制电路系统。

在车载电路中采用了MC9S128单片机作为主控制模块，连接驱动电路的电动机工作，电动机的正反转对应车门的开关。

The number of cars increased, the number of vehicle thefts increased year by year. Fearing theft of vehicles has become a concern for every vehicle owner. Therefore, study on high-performance automotive anti-theft alarm system has an important application value. At present, the rolling code encryption technology and wireless remote control technology are already very mature. Those technologies have been introduced into car anti-theft system. It is a new development direction.This topic design a car that can remote control the switch. This design on the key signals to control vehicles door motor, the doors can be opened or closed. HCS301 encoding chip rolling was adopted to achieve the function as the core module, key code encoder and matching TDH6301 decoding chip, so as to design a high reliability and safety of the car door control circuit system. In automotive circuit adoptedMC9S128 single-chip microcomputer as the main control module, connection work power circuit of the motor, motor and reversing switch for the door.Key words: HCS301 encoding chip;TDH6301 decoding chip;MC9S128 single-chip目录引言............................................................................................................................ -
