基于GPS和SIM300的汽车防盗系统设计

Design of Car Alarm Against Theft System based on GPS and SIM300

设计了一个基于GPS的防盗系统,该系统采用ARM7芯片LPC2131为控制核心,将GPS模块传送过来的数据包进行解析,并对解析出的数据(经度、纬度、速度等位置信息)进行处理和判断.然后在液晶屏上显示相应位置信息.如果判断到汽车可能处于被盗时,则声音报警,并通过SIM300模块,向车主发出报警信息.

A security system is designed based on GPS adopting ARM7 chip of LPC2131 as the control core.The data packet is transmited by the GPS module,and then analyzed including longitude,latitude,speed and so on. Finally the relevant information is displayed in the LCD screen. If it detects that the car is likely to be stolen,the it alarms through the voice and sends the alarm information to the ower via SIM300 module.
