基于ARM处理器的汽车智能防盗系统的应用研究
摘要
随着经济的迅速发展,人们的生活水平不断得到提高,私家车的数量越来越多。但与此同时,汽车被盗的数量每年也以惊人的速度不断飙升,给人们带来了巨大的经济损失。因此,汽车防盗产品已成为当代汽车必不可少的装备。但传统的汽车报警系统存在很多的问题,如作用距离短、可靠性低等。在分析汽车防盗系统现状和发展趋势的基础上,设计了基于ARM、GPRS和GPS的网络智能型汽车防盗系统。
首先根据汽车防盗系统的基本组成、工作原理及对防盗系统的性能要求,对汽车防盗系统进行了总体设计。在硬件设计上,从提高系统的运行速度和数据处理能力出发,采用ARM微处理器——S3C44B0X作为主控制器,并根据汽车防盗的功能需要设计了相应的数据存储、数据采集、GPS定位、GPRS通信、CAN总线接口等硬件模块,进行数据采集、监控终端防盗报警控制以及远程监控。
其次,为了满足汽车防盗系统的实时性和处理复杂多任务的需要,本系统监控终端核心控制器移植了μC/OS-Ⅱ嵌入式实时操作系统,建立了系统的软件平台,并在该平台上进行了应用软件设计。控制器采集定位数据,经GPRS网络发送短消息给车主手机以及接入Internet传送数据到监控中心两种方式,来实现远程监控和报警。
再次,利用Visual C++6.0及Access数据库技术,设计了监控中心PC的监控软件。通过该软件可实时监控汽车当前的状态,并可实现历史数据和报警电话的查询等功能。
本论文重点研究了利用ARM微控制器采集定位数据,并通过GPRS网络实现与监控中心PC和车主手机的通信,从而达到远程防盗的功能。最后,在实验室环境下对该系统进行了模拟调试,系统运行良好,能够实现定位数据采集及远程防盗的目的,具有较好的实时性和可靠性。
With the rapid development of economy, people’s lives have improved a lot, and more and more people buy automobile. At the same time, however, the numbers of thefts of automobiles are rising every year, which makes people suffer from tremendous economic loss. Hence, the system of guard against theft becomes an absolutely necessarily equipment of today’s vehicles. However, the traditional guard systems have too much limitation, such as close distance, bad reliability, and etc. On the basis of the research of vehicle guard system status and development trends, the design of vehicle guard system based on ARM, GPRS and GPS is proposed.
At first, in accordance with the components and the working principle of the vehicle guard system, the design of the vehicle guard system was proposed in this paper first. In hardware design, ARM MPU-S3C44B0X was used as the main control unit to improve the operating speed of the system and data processing capabilities. Moreover, the data storage, sensor, GPS positioning, GPRS communication, CAN-bus interface modules were designed based on the function requirement of the system.
Secondly, in order to satisfy the demand of real-time ability and multi-task management,μC/OS-Ⅱ, the embedded real-time operating system, was transplanted. On this basis, the application software was designed. In order to realize the distant monitoring and alarming, the controller collected the GPS data and sent it to the owner’s mobile phone though GPRS, And at the same time, the GPS data is sent to the monitoring center PC through Internet.
In addition, Visual C++6.0 and Access database technology were applied to design the PC monitoring software. And via this software we can observe the current statues of the car. Furthermore, we can achieve the historical data and alarm phone number.
The research of GPS data collecting by the controller and the communication with the monitoring center and the owner’s mobile phone via GPRS is the emphases of this paper. Finally, through the simulation and debugging in the lab environment, the system run well and realized the function of GPS data acquisition and distant alarming. And the system is proved to have the advantages of high data acquisition speed and good reliability.
