摘要
介绍了如何以AT89C52单片机作为控制核心控制GSM模块,实现发送短信、拨打报警电话的汽车防盗报警系统。该系统使用人体红外传感器探测报警信号,当红外传感器接收到报警信号时,单片机通过向GSM模块发送AT指令控制GSM模块发送报警短信或拨打报警电话。本汽车防盗系统利用GSM手机网络对汽车进行24小时无距离全方位监控,当汽车出现警情时,立即发送报警短信并拨打电话报告车主。GSM技术打破了传统汽车防盗系统的范围瓶颈,实践证明该系统稳定可靠。
A car anti-theft alarming system with the functions of sending SMS and dialing alarming numbers was introduced in this paper. In this system AT89C52 SCM is used as core control module to control the GSM module. Meanwhile the body infrared sensor performs to detect the alarming signals. Once the sensor receives alarming signals SCM will send AT instructions which controls GSM to send alarming signals or dialing alarming numbers as soon as possible. By this alarming system your car will be under monitoring all day from all aspects. As a result, the owner will get informed in time if something wrong happens. A great breakthrough on enlarging the monitoring range has been made by GSM technology. Also practice has proved the stability and reliability of this system.
