伴隨著社會(huì)的發(fā)展，人們的生活質(zhì)量不斷提高，擁有了更多的奢飾品，因此防盜就成了一項(xiàng)重要的課題。本次畢業(yè)設(shè)計(jì)的紅外線防盜報(bào)警器是基于電源電路給整個(gè)電路提供+5V電壓，通過(guò)紅外線發(fā)射和接受系統(tǒng)來(lái)感應(yīng)是否有人闖入，并通過(guò)單片機(jī)系統(tǒng)向聲光報(bào)警電路發(fā)出信號(hào)，達(dá)到聲光報(bào)警的目的。論文首先簡(jiǎn)單介紹了紅外線防盜報(bào)警器的發(fā)展背景、基本電路結(jié)構(gòu)和工作原理，以及國(guó)內(nèi)紅外線防盜報(bào)警器的發(fā)展?fàn)顩r，然后結(jié)合應(yīng)用電路具體介紹了該應(yīng)用電路的工作原理。論文詳細(xì)論述了電源電路的具體變壓、整流、濾波、穩(wěn)壓過(guò)程，以及通過(guò)單片機(jī)系統(tǒng)內(nèi)部程序的設(shè)定來(lái)區(qū)分紅外線接受端電壓的變化，并通過(guò)單片機(jī)來(lái)控制聲光報(bào)警電路，最后通過(guò)555定時(shí)器來(lái)輸出穩(wěn)定的信號(hào)。最后，附錄部分附有本次設(shè)計(jì)所應(yīng)用到的電路原理圖。

Infrared Burglar Alarm
Abstract
The design and development of graduation infrared burglar alarm is based on the power supply circuit for the entire circuit to provide +5 V voltage, through an infrared transmitting and receiving system whether the intrusion sensors, SCM system and through to the sound and light alarm circuit sent a signal to sound and light alarm purposes. The paper introduced the simple anti-theft alarm infrared background of the development, basic circuit structure and working principle, Infrared and domestic security alarm state of development, then combined application specific circuits on the application of circuit theory. Papers discussed in detail the specific power rectifier circuit, rectifier, filtering, Regulators process. SCM system, as well as through the creation of internal procedures to distinguish between infrared receiving terminal voltage changes. and through MCU to control sound and light alarm circuit, the final adoption of 555 timer output signal stability. Finally, the appendix attached to this part of the design applied to the circuit diagram.
