摘要
目的 针对近年来频发的汽车被盗现象,设计一种基于单片机的GSM汽车防盗系统,并给出该系统的总体设计方案。方法 研究以STC89C51单片机和GSM移动网络技术为核心,结合Keil、AltiumDesigner等软件,设计汽车安全防盗系统。该系统主要由STC89C51单片机、GSM模块、振动传感模块、无线收发模块、声光报警模块和液晶数据显示模块组成。结果 通过振动传感器检测车辆异常信号,实现汽车的声光报警,同时利用GSM模块通过通信网络将报警信息发送给指定用户,实现汽车的远程报警。设计通过软件程序和硬件电路相结合,具有系统误报率低、安装和配置容易、使用方便、模块成本低、功耗低等优点。结论 该设计克服了传统的报警系统报警范围小的缺点,车主可以通过手机短信及时获得报警信息,在汽车防盗领域有很好的应用前景。
Objective Aiming at the phenomenon of car theft in recent years,a GSM car anti-theft system based on single-chip microcomputer was designed,and the overall design scheme of the system was given.Methods The research focused on STC89C51 single-chip microcomputer and GSM mobile network technology.Keil,Altium Designer and other softwares were used to design the car security anti-theft system.The system was mainly composed of STC89C51 single chip microcomputer,GSM module,vibration sensing module,wireless transceiver module,sound and light alarm module and liquid crystal data display module.Results The system detected the abnormal signal of the vehicle through the vibration sensor,realized the sound and light alarm of the car,and simultaneously transmitted the alarm information to the designated user through the communication network by the GSM module to realize the remote alarm of the automobile.The design combines software program and hardware circuit,which have the advantages of low false alarm rate,easy installation and configuration,convenient use,low module cost and low power consumption.Conclusion The design overcomes the shortcomings of the traditional alarm system with a small alarm range.The vehicle owner can obtain the alarm information in time through the short message.And the design has a good application prospect in the field of automobile anti-theft.
