- 摘要
伴隨著社會的發展，人們的生活質量不斷提高，擁有了更多的奢飾品，因此防盜就成了一項重要的課題。本次畢業設計的紅外線防盜報警器是基于電源電路給整個電路提供+5V電壓，通過紅外線發射和接受系統來感應是否有人闖入，并通過單片機系統向聲光報警電路發出信號，達到聲光報警的目的。論文首先簡單介紹了紅外線防盜報警器的發展背景、基本電路結構和工作原理，以及國內紅外線防盜報警器的發展狀況，然后結合應用電路具體介紹了該應用電路的工作原理。論文詳細論述了電源電路的具體變壓、整流、濾波、穩壓過程，以及通過單片機系統內部程序的設定來區分紅外線接受端電壓的變化，并通過單片機來控制聲光報警電路，最后通過555定時器來輸出穩定的信號。最后，附錄部分附有本次設計所應用到的電路原理圖。

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.
