摘要针对车辆防盗以及营运监管需求的日益增长，研究智能防盗及定位装置成为当前汽车电子研究的热点之一。本课题主要设计一种基于GPS/BD和GSM 的智能汽车报警装置。

在分析实际应用需求的前提下，制定了基于GPS/BD和GSM模块的总体方案，车载终端采用单片机Atmega162为控制核心，通过GPS/BD接收模块（UM220）获取车辆的地理位置、时间以及速度等信息，经单片机判断车辆是否在非法情况下进行了移动，同时给设置的通信号码通过GSM以短信方式实时告知车辆的具体位置，并可以响应车主的短信实现声音报警或自动熄火（机械保护）等功能。61117

本文主要完成了系统总体设计以及主要模块的软硬件设计。

Title    Intelligent Automobile Alarming Device Based On GPS_BD And GSM Technology 

Abstract Research of intelligent anti-theft and positioning device has become a hot research spot of automotive electronics for acquiring the growing demands of vehicle anti-theft as well as operation and supervision.

With the actual application requirements were analyzed, the general design based on GPS/BD and GSM module was presented in this paper. Vehicle terminal uses Atmega162 as the control core of the module. Using GPS/BD Receiver Module (UM220) to obtain vehicle’s location, time, and speed information, after signal processing the microcontroller determines whether the vehicle is in special situations. Meanwhile, Terminal uses SMS to inform the exact location of the vehicle in real time by GSM. Moreover, terminal also can respond to the owner’s SMS to implement audible alarm or automatic flame failure (mechanical protection) and other functions.

The system design and the main module hardware and software design are implemented in this paper. 

Key words: Positioning and monitoring, BeiDou System, GPS, GSM,SCM, C + + Programming
