對(duì)射式紅外線防盜報(bào)警器的設(shè)計(jì)

摘  要
本系統(tǒng)是基于AT89S52單片機(jī)控制的紅外線防盜報(bào)警器，主要由紅外線發(fā)射部分、紅外線接收部分、單片機(jī)以及聲光報(bào)警部分組成?？赏ㄟ^發(fā)射電路發(fā)射的紅外線被遮擋時(shí)控制報(bào)警系統(tǒng)報(bào)警, 通過單片機(jī)控制報(bào)警電路的運(yùn)行，并能同時(shí)進(jìn)行聲光報(bào)警，用紅外線收發(fā)管進(jìn)行檢測，安裝隱蔽，不易被發(fā)現(xiàn)；探測信號(hào)采用脈沖信號(hào)，節(jié)能且抗干擾。系統(tǒng)可以探測到一定范圍內(nèi)的人的闖入, 可以應(yīng)用在安防范圍比較確定的情況下。采用這種方法設(shè)計(jì)的防盜報(bào)警器具有成本廉價(jià)和探測效果好的優(yōu)點(diǎn)，有著廣闊的市場前景。

ABSTRACT
The system is a infra-red anti-theft alarm controled by single-chip AT89S52, including infra-red part of the launch, part of the infrared receiver, microcontroller, as well as part of sound and light alarm.The system will alarm when infrared ray has been blocked , through the single-chip microcomputer to control the operation of alarm circuit, and at the same time sound and light alarm, with infrared transceiver test tube, install hidden, can not easily be found; detection signal using pulse signal, energy-saving and anti-jamming. This system can detect a certain person within the scope of the intrusion, security can be applied to determine the scope of the case. Designed using this method of anti-theft alarm and detection in a cost-effectiveness of low-cost best advantages, has broad market prospects.

KEY WORDS: Single chip microcomputer；Infrared anti-theft alarm; Sound and light alarm
