摘要
设计了一种双向汽车防盗器。该防盗器由主机和遥控器组成,采用半双工通信方式。主机可检测车身内的多个触发源,实现防盗自动报警,并通知遥控器进行远程报警。此外主机还能完成遥控器设定的车门自动上下锁、报警自动恢复、报警紧急解除等功能。使用自定义的无线通信协议,数据传输采用PWM编码,并使用FSK调制和解调。该防盗器具有实时性强、可靠性高、功耗低等优点。
A two way car alarm was designed. The alarm, in which the half-duplex communication mode is adopted, consists of two main parts： the remote controller and the mainframe. The mainframe can detect multiple trigger sources inside a car body so as to implement the automatic alarm and remote control for remote alarm notification. In addition, the mainframe can complete the set functions, such as automatic lock and open of doors, automatic recovery of car alarm and urgent release of alarm. According to the custom wireless communications protocol, PWM encoding, and FSK modulation and demodulation are employed for the data transmission. This anti-theft device has the advantages of real-time, high reliability and low power consumption.
