A variety of highgrade household electrical appliances and the valuables have for many families. However, some lawless elements are also more and more. This is seen most security awareness is not strong enough. Causing steal phenomenon it is often seen. Therefore, more and more households in property safety is concerned about. Security has bee an important topic. Infrared antitheft alarm is a kind of intelligent alarm system, can greatly improve the safety degree of the households, effectively guarantee the residents39。本論文先后介紹了紅外線防盜報警器的意義、發(fā)展背景、發(fā)展前景、系統(tǒng)的基本電路結構和系統(tǒng)軟件的設計。在CPU程序運行以后控制輸出口電平使得蜂鳴器與發(fā)光二極管組成的聲光報警電路同時進行聲光報警。由于紅外線是不見光，有很強的隱蔽性和保密性，因此在防盜、警戒等安保裝置中得到了廣泛的應用，通過紅外線發(fā)射和接受系統(tǒng)來感應是否有人闖入，如果探測到有人闖入，那么系統(tǒng)的聲光報警電路會發(fā)出警鳴聲給人們以提醒。防盜就成了一項重要的課題。然而一些不法分子也是越來越多。 教學單位電子電氣工程系學生學號 編號 本科畢業(yè)設計題　　目　紅外線防盜報警器設計　學生姓名　　　　專業(yè)名稱　電氣工程及其自動化　指導教師　　　　　 2012年3月8日24紅外線防盜報警器設計摘要近年來，隨著改革開放的深入發(fā)展，電子電器的飛速發(fā)展，人民的生活水平有了很大提高。各種高檔家電產(chǎn)品和貴重物品為許多家庭所擁有。因此，越來越多的居民家庭對財產(chǎn)安全問題十分擔憂。紅外線防盜報警器是一種智能報警系統(tǒng)，可以大大提高了居民家庭的安全程度，有效保證了居民的人身財產(chǎn)安全。該系統(tǒng)以單片機AT89S52系列為核心，采用紅外線發(fā)射管和紅外線接收管為發(fā)射和接收裝置，由反相器芯片反相間接控制CPU工作。并通過單片機系統(tǒng)向聲光報警電路發(fā)出信號，達到聲光報警的目的。關鍵詞：報警器；AT89S52單片機；紅外線發(fā)送；紅外線接受；The design of infrared antitheft alarm systemAbstractIn recent years, with the deepening of reform and openingup, electronic and electrical appliances rapid development, people39。 personal and property safety. Because infrared is not exposed to light, has strong confidentiality and secrecy, therefore in security, alert security device has been widely used, through the infrared transmitting and receiving system for sensing whether someone is breaking into, if the detected someone broke in, then the system will send out alarm sound and light alarm circuit sounds to the people to remind. The system based on singlechip AT89S52 series as the core, using the infrared emission tube and the infrared receiving tube for transmitting and receiving device, by an inverter inverting indirect control CPU chip. In the CPU program to run after the control of output level makes the buzzer and the light emitting diode prising an acoustooptic alarm circuit at the same time the sound and light alarm. And through the single chip microputer system to sound and light alarm circuit sends out signals to alarm, the purpose of. This paper has introduced the infrared antitheft alarm significance, development background, development prospects, system basic circuit structure and the software system design..Keywords:Power Circuit。 Infrared send ；Infrared receive。傳統(tǒng)的機械式（防盜網(wǎng)、防盜窗）家居防衛(wèi)在實際使用中暴露出一些隱患，正如國務院下達的《關于住宅小區(qū)禁止
