摘 要
本課題是基于GPRS的遠程監(jiān)控汽車防盜，具體是要實現(xiàn)一個電子化，智能化，高可靠性的系統(tǒng)。這個系統(tǒng)把用戶的手機或計算機作為整個系統(tǒng)的監(jiān)控終端，短消息/GPRS數(shù)據(jù)作為車載模塊與手機的傳輸媒介。系統(tǒng)的基本工作原理是這樣的，當(dāng)系統(tǒng)正常工作時，如果受到非法侵襲(如玻璃被打破，車門被撬)，這時通過安裝在車上的傳感器的檢測，首先發(fā)出聲光報警，然后將信息提供給車載模塊，車載模塊再將信息處理判斷后，以短消息或GPRS的形式將具體情況發(fā)送到用戶手機或網(wǎng)站。由于使用GSM/GPRS網(wǎng)絡(luò)作為系統(tǒng)通信的媒介，凡是GSM/GPRS網(wǎng)絡(luò)能覆蓋的地方就能保證系統(tǒng)正常運行，所以系統(tǒng)基本不受距離的限制。
本系統(tǒng)主要由單片機，振動傳感器以及SIM300模塊組成，借助最可靠、最成熟的GSM/GPRS網(wǎng)絡(luò)，以最直觀的短消息形式，直接把汽車的遇險情況反映到車主的手機屏幕上，以便車主在第一時間發(fā)現(xiàn)險情，從而進行必要的防范。它主要是采用振動傳感器進行檢測，把感應(yīng)到的振動信號轉(zhuǎn)換為電信號，單片機是該系統(tǒng)的主要部件，通過GSM/GPRS模塊發(fā)送信息.
將這種技術(shù)應(yīng)用于汽車遠程防盜報警系統(tǒng)，彌補了傳統(tǒng)防盜報警器報警方法的不足，并且降低成本、不受地域限制、報警準(zhǔn)確迅速，能夠達到汽車遠程控制防盜報警系統(tǒng)的要求。

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/GPRS network as a system of communication media, GSM/GPRS network 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 microcomputer, pressure sensors and SIM300 modem. It uses the most reliable, most mature GSM/GPRS mobile network, 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 microcomputer is the main components of the system. This system dispatches a short message by GSM/GPRS modem.
The technology used in car remote anti-theft alarm system, make up the traditional methods of burglar alarm alarm deficiencies, and lower cost, without geographical restrictions, warning is accurate and quick, able to reach the remote control car anti-theft alarm system requirements.

KEY WORDS：GPRS modem, single-chip microcomputer, vibration sensors, vehicle anti-theft
