基于GPRS的车用防盗报警器设计(硬件)
摘要
本课题是基于GPRS的远程监控汽车防盗,具体是要实现一个电子化,智能化,高可靠性的系统。这个系统把用户的手机或计算机作为整个系统的监控终端,短消息/GPRS数据作为车载模块与手机的传输媒介。系统的基本工作原理是这样的,当系统正常工作时,如果受到非法侵袭(如玻璃被打破,车门被撬),这时通过安装在车上的传感器的检测,首先发出声光报警,然后将信息提供给车载模块,车载模块再将信息处理判断后,以短消息或GPRS的形式将具体情况发送到用户手机或网站。由于使用GSM/GPRS网络作为系统通信的媒介,凡是GSM/GPRS网络能覆盖的地方就能保证系统正常运行,所以系统基本不受距离的限制。
本系统主要由单片机,振动传感器以及SIM300模块组成,借助最可靠、最成熟的GSM/GPRS网络,以最直观的短消息形式,直接把汽车的遇险情况反映到车主的手机屏幕上,以便车主在第一时间发现险情,从而进行必要的防范。它主要是采用振动传感器进行检测,把感应到的振动信号转换为电信号,单片机是该系统的主要部件,通过GSM/GPRS模块发送信息.
将这种技术应用于汽车远程防盗报警系统,弥补了传统防盗报警器报警方法的不足,并且降低成本、不受地域限制、报警准确迅速,能够达到汽车远程控制防盗报警系统的要求。

The VEHICLE ANTI-THEFT ALARM SYSTEM DESIGN
BASED ON GPRS
ABSTRACT
This issue is based on the GPRS car alarm remote monitoring, specifically to achieve an electronic, intelligent, high-reliability systems. The system to the user’s mobile terminal as a monitor of the system,short message/GPRS data as a vehicle module and cell phone transmission medium. The basic working principle of the system is that when the system work, if by the illegal invasion (such as the glass was broken, the door had been broken), this time by installing sensors in the vehicle testing, the first audible alarm, and then information provide to the vehicle module, vehicle information processing module then judge after the form of a short message or GPRS sent to the user specific mobile phone or website. The use of GSM/work as a system munication media, GSM/work to cover all areas will be able to ensure the normal running, so the system basically free from the constraints.
This system consists of single-chip puter, pressure sensors and SIM300 modem. It uses the most reliable, most mature GSM/GPRS work, in order to tell the state of vehicle to the owners in the form of short message in Chinese. This will help owners find the first time danger of electric vehicles in order to carry out preventive. It uses sensors to detect vibration , the vibration signal is converted to electrical signal. Single-chip puter is the pone
