【摘要】 随着经济的发展,人们的生活水平不断提高,私家车的数量越来越多,但与此同时,汽车被盗事件也越来越多。因此,汽车防盗产品已成为当代汽车必不可少的装备,但传统汽车防盗系统存在作用距离短、可靠性低等缺点。本文给出了基于GPRS和GPS技术,采用ARM作为主控制器来实现的汽车防盗系统,在传感器模块检测到车辆被偷窃后,系统通过GPRS模块通知车主,车主可以通过短信对汽车进行远程锁死油路、声音报警等操作,并通过GPS模块获取车辆的GPS信息。系统在GPRS覆盖的范围内,可实现人车通信,实现对汽车状态全天候的检测与控制。论文主要对以下内容进行了研究：(1)根据汽车防盗系统要实现的目标,对汽车防盗系统进行了总体设计。将系统划分为传感器模块、GPRS模块、GPS模块和控制模块,并简要介绍了GPRS的原理和技术优势及GPS的定位原理。(2)采用ARM LPC2368微处理器作为主控制器,根据系统的功能需要完成了传感器检测模块、GPRS通讯模块、GPS定位模块、布防模块和远程控制模块等模块的选型和硬件电路设计。(3)汽车防盗系统的软件设计,包括传感器检测模块软件设计、GPRS模块软件设计和GPS模块软件设计。在简要分析SIM300串口通信控制、AT指令、短信息通讯的PDU模式分析和GPS定位信息提取的基础上,完成了加速度传感器、超声波传感器、发送PDU码短信息以及GPS定位任务等主要应用程序的设计。系统可实现报警信号的检测、车主与系统之间的通讯、GPS定位信息的获取、远程控制的操作,具有较高的实际应用价值。更多还原

【Abstract】 With the rapid development of economy, people’s living standard enhance unceasingly, and the amount of private cars increases gradually. At the same time, more and more car stolen affairs happened around us. The system of guard against theft has become an absolutely necessary equipment of vehicles; however the traditional guard systems have too much shortcoming, such as short distance and low reliability. Based on GPRS and GPS technology, this paper realizes car alarm system using ARM as the main controller. When the sensor module detects theft of car, the system would inform the owner through GPRS module by SMS, then the owner could give oders to stolen car remotely, like locked oil, voice alarm and getting GPS information through the GPS module. The system can realize Human-car corresponding,all-weather detect and control under the GPRS.Main contents in this paper include:(1) This paper gives an overall design of the system of guard against theft according to needing objectives, then devides the system into GPRS module, GPS module and control module, and briefly introduces the principle and technical advantage of GPRS and GPS positioning principle.(2) Using the ARM LPC2368 microprocessor as the main controller, according to the system’s function this issue completes the sensor module, GPRS communication module, GPS module, protection modules and relay control module selection and hardware circuit design.(3) The software design of system of guard against theft includes software design of sensor module, software design of GPRS module and software design of GPS module. On the basis of a brief analysis about control mechanism of SIM300 serial interface communication, AT instructions, PDU mode analysis of short information communication and extraction of GPS positioning information, thei paper implements some main applications, such as software design of acceleration sensor, software design of ultrasonic sensors, sending short information of PDU mode communication of PDU mode and the design of GPS positioning task.System can realize detection trespassed, communication between owner and system, acquiring GPS positioning information, control system open and remote control operation, with high practical value.更多还原
