基于GSM的智能车牌防盗报警装置的设计

摘要

由于生活中汽车的数量与日俱增,汽车车牌的安全也成了很多人关注的问题。本装置与其他车牌防盗装置相比更加有效,通过霍尔效应传感器监测,在车牌紧固螺丝防护帽脱落的第一时间进行现场报警[1],起到警示作用,同时通过GSM通讯模块及时向车主手机发送车牌被撬信息,从而能及时阻止车牌被盗,详细叙述了本装置的设计背景,系统原理设计,硬件电路设计,给出了系统原理图,安装示意图和传感器电路图。%A increasing number of cars in our life has aroused public concern of license plate security.Comparing with other devices of plates guarding against theft,this device is more effective.Monitored by hall effect sensor,it alarmed the moment the tightened screw helmet falls,meanwhile,the car owner receive the mobile phone message of plate prying,so he can prevent license plates being stolen in time.The device＇s design background,principles of system design and hardware circuit design are stated.System schematic diagram,installation diagram and sensor circuit diagram are also given.
