基于C51的聲光報(bào)警設(shè)計(jì)


摘    要

本設(shè)計(jì)的目的在于把各種現(xiàn)代化的報(bào)警系統(tǒng)中的公共部分光電報(bào)警部分提取出來(lái)，獨(dú)立成系統(tǒng)。降低其他設(shè)計(jì)者開發(fā)新的報(bào)警裝置的時(shí)間成本。本設(shè)計(jì)的聲光報(bào)警系統(tǒng)是以at89c52單片機(jī)為核心，完成對(duì)輸入信號(hào)的條件判斷，并控制相應(yīng)的LED和蜂鳴器動(dòng)作，從而達(dá)到根據(jù)外部條件發(fā)出警報(bào)的目的。本設(shè)計(jì)最終實(shí)現(xiàn)了，紅外遙控對(duì)報(bào)警器進(jìn)行復(fù)位，多種頻率的聲音報(bào)警，和流水燈顯示。在此基礎(chǔ)之上又添加了液晶顯示模塊，能夠清楚的顯示單片機(jī)當(dāng)前的狀態(tài)。并增加了喇叭以改善發(fā)聲效果和報(bào)警方式。

ABSTRACT

Sound and light alarm system as a common alarm systems is widely used in area of  production and human life. The aim of the design is making the public part of the photoelectric alarm in the modern alarm system and lets the part work as a independent system. This design would help other designers reduce time cost for development. The design of sound and light alarm system is based on AT89C52 MCU core. LED corresponding the input signals fuction and buzzer control function to achieve the alarm according to the purpose of external conditions are performed in this design. In the design, infrared remote control of the alarm reset, multi-frequency sound alarm and the led water flow are finally realizied.  Additionally, the liquid crystal display module is added to clearly show the current state of SCM and a speaker is also designed to improve the sound effects and  alarm style .

Key words:  sound and light alarm, AT89C52, remote control, LCD display
