【導(dǎo)讀】隨著科技的發(fā)展和人們生活水平的提高，家居智能防盜成了越來越熱門的話題。課題貼近日常生活，又能很好地運(yùn)用所學(xué)的單片機(jī)知識(shí)，主要是針對(duì)家庭的安全問題，成不必要的損失。也可以外加傳感器，連接至報(bào)警系統(tǒng)上，將窗戶等需要監(jiān)測(cè)的地方與。大門構(gòu)成整體的監(jiān)控報(bào)警系統(tǒng)，對(duì)房屋進(jìn)行整體監(jiān)控。保證住戶的人身財(cái)產(chǎn)安全。本系統(tǒng)的設(shè)計(jì)中，采用51單片機(jī)為主控制器，用不同顏色的LED燈為裝態(tài)指示燈，LCD記錄報(bào)警時(shí)間，并通過繼電器控制給主人撥打電話。警告狀態(tài)，這個(gè)狀態(tài)在門開后觸發(fā)水銀開關(guān)使得，黃燈亮，蜂鳴響，LCD時(shí)間更新，處于警告狀態(tài)，并且識(shí)別是否是陌生人。后進(jìn)入正常狀態(tài)，如果不按下識(shí)別按鈕或者時(shí)間超過5s，則觸發(fā)報(bào)警狀態(tài)。動(dòng)，1分鐘后除了LCD時(shí)間顯示停止外其他模塊恢復(fù)正常工作狀態(tài)。等為狀態(tài)指示燈和系統(tǒng)時(shí)間顯示等顯示電路部分，綠色LED——P1^0,黃色LED—P1^1，2腳和3腳接晶振，并通過2個(gè)22uF的電容接地。以下為LCD1602的頭文件。
