【摘要】 随着汽车数量不断增多,汽车被盗案件也逐渐增多,汽车被盗问题已经成为普遍关注和急需解决的社会问题。尤其是当今社会,小排量的经济车型占市场主导,更加需要一种可靠、安全、使用方便、价格低廉的汽车防盗系统。本文研究一种基于GSM通信网络的汽车远程报警系统,引入双重防盗的概念,通过双重防盗来提高设防汽车的安全性。设计了系统总体方案,分别研究了系统的硬件和软件,并对传感器进行了校正,对其将来可能应用到的领域做了一些探讨和分析。全球移动通信系统(GSM)是一种发展已经非常成熟的数字移动通信系统,它不仅抗干扰能力强、而且所覆盖区域内通信质量也高。其中的短消息服务具有通信成本低、实现容易、频谱利用率高而且保密性好等特点。系统选用GSM网络作为通讯平台来完成远程信息的传输,详细研究了GSM的网络体系结构和短信息的通信原理。数据的传输方式主要采用短消息方式的Text模式;是通过AT指令来实现短消息的接收和发送,文中简单列出了一些常用的AT指令及其使用方法。将TC35i GSM模块和微控制器系统相结合,通过振动传感器和速度传感器来实现短消息报警和对汽车的双重防盗。系统的硬件设计中主要包括对TC35i的外围电路设计,对在片CAN控制器PSXC592的结构设计和智能传感器节点设计三个部分。系统的软件设计主要是指对GSM模块程序指令的设计和微控制器程序语言的设计。本文还详细介绍了遗传神经网络的原理,并且把该原理应用在对汽车传感器的非线性校正上。实验表明此方法具有很高的校正精度和较强的鲁棒性。更多还原

【Abstract】 As the increasing of cars, Cases of automobile theft are increased gradually, automobile theft has become an urgent social problem which is concerned by public. Especially in the market which is led by small discharge capacity and economical automobile, a kind of credible, safe, usable and cheap automobile burlary-resisting system is required.An automobile burglary-resisting system based on GSM module is designed in this paper. Dual burlary-resisting is introduced. The automobile security is greatly enhanced through dual burlary-resisting. It presents the system design as a whole, then presents the hardware and software design of system, at last adjusts the sensors, presents some discussions and analysis in the possible applying fields.GSM is a kind of developed digital mobile communication system. It has charactors of strong anti-interference ability and high communications quality in covering regions. Short Message Service has many good features such as simple realization, low-cost communications, high spectrum efficiency and good confidentiality. GSM network works as a plantform for the long-range information transmission. The paper makes a detailed explaination about the network architecture of GSM and short message correspondence theory. Short message using Text mode is the main mean of the data transmission; Short messages are received and sent through the AT commands. The article lists the commonly used AT commands and their usages. The system combines the MCU and TC35i GSM module.Sensor and speed sensor are used to implement message alarm and dual theftproof of automobile.Three main parts are included in the hardware design: external circuit of TC35i, instrctural design of on-chip CAN controller P8XC592 and the design of intelligent sensor nodes. The software design of the system refers to the procedures’ command of GSM module and the programming language design of the microcontroller.The paper also introduces the principles of genetic neural networks in detail. The sensors are nonlinear corrected by genetic neural networks. Experiments show that, this method of correction has high precision and strong robustness.更多还原
