摘要
 紅外技術(shù)應(yīng)用越來越廣泛和普及，因此我們選用AT89C51單片機(jī)為核心，以MT8880芯片和ISD1420芯片為輔助以及一些其他的外圍輔助電路，構(gòu)成了一個(gè)紅外自動(dòng)報(bào)警系統(tǒng)。紅外傳感器既安全又隱蔽，而且技術(shù)十分成熟。因此選用了紅外傳感器。該系統(tǒng)的主要功能是:利用紅外傳感器輸入報(bào)警信息給CPU,CPU在通過語音芯片產(chǎn)生報(bào)警并把相應(yīng)的報(bào)警信息通過話機(jī)傳給用戶,用戶可以通過話機(jī)對(duì)系統(tǒng)進(jìn)行操作,可以及時(shí)解除錯(cuò)誤報(bào)警.
 這個(gè)系統(tǒng)由我們?nèi)齻�(gè)人合作完成。主要有信號(hào)檢測(cè),語音芯片和軟件部分.我主要是負(fù)責(zé)軟件部分.軟件部分主要由系統(tǒng)初試化,密碼檢測(cè),振鈴音檢測(cè),自動(dòng)摘機(jī)等部分組成

ABSTRACT
 Infrared Technology applies more and more and extensively with universality, so we choose to use the AT89C51 a single slice machine for the core, taking the MT8880 chips and ISD1420 chips as assistances and some other outer circle assistance electric circuit, constitute a red outside report to the police system automatically. Infrared Sensors is safe and concealment, and the technique is very mature. Therefore chose to use a red unauthorized biography feeling machine. The main function of that system BE: make use of a red unauthorized biography feeling machine importation to report to the police an information to the CPU, the CPU is passing a speech chip's creation to report to the police and correspond of report to the police an information to pass customer through a words machine, the customer can pass words machine to carry on an operation to the system, can relieve a mistake to report to the police in time.
   This system is been three personal cooperation completions by us. Mainly there are signal examination, speech chip and software part. I mainly is be responsible for software part. The software part is mainly turned by system first attempt, the password examines, flapping a bell sound examination, taking off machine automatically etc. part constitute.
