摘要
汽车防盗门控系统是汽车安全的保障,传统的遥控门禁系统已经无法满足广大用户的需求,免持式被动无钥匙门禁系统正迅速成为汽车远程无钥匙门禁应用的主流。该设计在硬件设计中芯片选择了STM32F103、2.4G无线通讯模块使用设计、RFID射频读卡器模块使用设计、电源电路设计。软件设计详述了SPI总线和CAN总线通讯协议、滚码加密方案设计、2.4G通讯模块驱动、RFID射频模块驱动。实现了较远距离有效通讯,有效通过遥控器对汽车进行开锁操作,通讯过程中使用滚码加密的方式,使系统具有安全性、保密性,使用RFID射频方式近距离识别遥控,遥控在车身附近,执行开门动作。
Car security door control system is the security of the car,the traditional remote control access control system has been unable to meet the needs of the majority of users,hands-free passive keyless access control system is rapidly becoming the mainstream of remote keyless access control application in cars.In the hardware design,STM32 F103,2.4 g wireless communication module,RFID radio frequency card reader module and power circuit are selected.The software design details SPI and CAN bus communication protocols,roll code encryption scheme design,2.4 g communication module driver,RFID rf module driver.Effective communication is realized over a long distance.The lock is unlocked effectively through the remote control.Rolling code encryption is used in the communication process to make the system secure and confidential.
