基于單片機(jī)的指紋門(mén)禁設(shè)計(jì)STC89C52

功能：

研究?jī)?nèi)容：本課題以單片機(jī)為核心采用C語(yǔ)言來(lái)開(kāi)發(fā)一指紋電子密碼鎖。系統(tǒng)擬在Altium?Designer9開(kāi)發(fā)平臺(tái)上設(shè)計(jì)原理圖，并繪制PCB并制成單片機(jī)開(kāi)發(fā)板，然后根據(jù)原理圖將相關(guān)元器件焊接到開(kāi)發(fā)板上。軟件部分在Keil?uVision4開(kāi)發(fā)平臺(tái)上進(jìn)行相關(guān)代碼的編寫(xiě)和調(diào)試。然后利用串口助手工具將代碼下載到開(kāi)發(fā)板進(jìn)行運(yùn)行，觀(guān)察硬件各模塊是否可以正常運(yùn)行。以及測(cè)試結(jié)果是否能夠滿(mǎn)足需求，便于及時(shí)調(diào)整設(shè)計(jì)。

課題的主要任務(wù)是設(shè)計(jì)出一個(gè)可以錄入指紋，并可對(duì)錄入指紋進(jìn)行匹配比較，如果正確即可開(kāi)鎖。

1. 設(shè)置有管理員密碼，管理員密碼內(nèi)置不可修改，密碼具有掉電存儲(chǔ)功能。
2. 輸入管理員密碼后進(jìn)入指紋錄制模式，錄入自己的指紋
3. 錄制成功后，支持指紋開(kāi)鎖，指紋匹配成功后，繼電器吸合表示開(kāi)門(mén)，并且語(yǔ)音提示開(kāi)鎖成功
4. 當(dāng)遇到震動(dòng)時(shí)，語(yǔ)音提示，請(qǐng)勿強(qiáng)行開(kāi)鎖，并且可以通過(guò)sim模塊發(fā)送報(bào)警短信
5. 單片機(jī)內(nèi)置用戶(hù)密碼，匹配成功后可以通過(guò)app使用密碼開(kāi)鎖。

重點(diǎn)難點(diǎn)：指紋的錄制與識(shí)別，語(yǔ)音提示，并且具有報(bào)警系統(tǒng)，當(dāng)遇到震動(dòng)時(shí)時(shí)可以發(fā)出語(yǔ)音報(bào)警和sim短信報(bào)警，硬件元器件較多使用了大量串口，pcb排版要注意，避免各個(gè)部件之間的干擾。
