🔥 這兩年開始畢業(yè)設(shè)計和畢業(yè)答辯的要求和難度不斷提升，傳統(tǒng)的畢設(shè)題目缺少創(chuàng)新和亮點，往往達不到畢業(yè)答辯的要求，這兩年不斷有學(xué)弟學(xué)妹告訴學(xué)長自己做的項目系統(tǒng)達不到老師的要求。

為了大家能夠順利以及最少的精力通過畢設(shè)，學(xué)長分享優(yōu)質(zhì)畢業(yè)設(shè)計項目，今天要分享的是

1 簡介

針對當前的疫情形勢，設(shè)計一款智能防疫門禁系統(tǒng)。本系統(tǒng)由STM32F103C8T6單片機核心板、彩屏液晶顯示電路、語音播報電路、非接觸測溫傳感器電路、舵機驅(qū)動電路、WIFI模塊、按鍵電路及電源組成，能夠采集人體溫度、記錄人流量，測量溫度對比溫度閾值，當測量溫度低于溫度閾值時，液晶顯示“狀態(tài):正常”，語音播報“溫度正常”，舵機動作（相當于打開閘門）；如果測量溫度超過設(shè)置閾值，液晶顯示“狀態(tài):注意！異常”，語音播報“請注意 溫度異常”，舵機不動作（不允許通過）。

總體方案設(shè)計圖

彩屏液晶顯示
采用1.8寸128X160像素tft屏幕，該屏幕采用ST7735S驅(qū)動芯片，通過14pin、0.5mmFPC接口（本來是想直接自己焊接FPC連接座的，然鵝技術(shù)不達標，焊了兩個都報廢了，于是換成了直插的）與單片機相連，通過SPI串口與單片機進行通信，用來顯示所測溫度或顯示其它必要信息。

語音播放芯片
采用NV020C-SOP8語音芯片，該芯片內(nèi)置一組PWM輸出器可直推0.5W喇叭，支持13bit的DAC輸出，也可外接功放模塊；采用靈活的多種操作模式（邊沿按鍵觸發(fā)，電平觸發(fā)、隨機按鍵播放、順序按鍵播放等）；外圍電路簡單，僅需一個耦合電容。靜態(tài)電路小于2uA；本系統(tǒng)中采用一線制控制模式，單片機僅需1個IO口輸出時序信號，即可控制該芯片輸出音頻。

非接觸測溫傳感器
采用GY-906-DCC模塊,該模塊體積小巧，內(nèi)部自帶環(huán)境溫度補償和線性校準算法，通過SPI通信與單片機進行數(shù)據(jù)交換，當溫度超過設(shè)定的閾值時，單片機進行及時的顯示和邏輯處理，本模塊精度非常之高，完全可以滿足無接觸測溫功能需求（本項目用的是10cm精度的）。

WIFI模塊
ESP12F 系列模組是深圳市安信可科技有限公司開發(fā)的一系列基于樂鑫ESP8266的低功耗UART-WiFi芯片模組，可以方便地進行二次開發(fā)，接入云端服務(wù)，實現(xiàn)手機3/4G全球隨時隨地的控制，加速產(chǎn)品原型設(shè)計。模塊核心處理器 ESP8266 在較小尺寸封裝中集成了業(yè)界領(lǐng)先的 Tensilica L106 超低功耗 32 位微型 MCU，帶有 16 位精簡模式，主頻支持 80 MHz 和 160 MHz，支持 RTOS，集成 Wi-Fi MAC/ BB/RF/PA/LNA，板載天線。支持標準的 IEEE802.11 b/g/n 協(xié)議，完整的 TCP/IP 協(xié)議棧。用戶可以使用該模塊為現(xiàn)有的設(shè)備添加聯(lián)網(wǎng)功能，也可以構(gòu)建獨立的網(wǎng)絡(luò)控制器。本系統(tǒng)采用該模塊進行數(shù)據(jù)的上傳，可以實時將數(shù)據(jù)上傳給后臺服務(wù)器，進行數(shù)據(jù)的存儲和大數(shù)據(jù)處理等。

主控模塊
STM32F103C8T6(STM32F103C6T6也可以)是一款基于ARM Cortex-M 內(nèi)核STM32系列的32位的微控制器，程序存儲器容量是64KB，需要電壓2V~3.6V，本系統(tǒng)采用stm32f103c8t6當主控模塊，實時采集紅外傳感器獲取溫度，如果溫度低于或高于指定閾值時，操作TFT顯示屏顯示溫度異常和語音模塊播報，同時控制舵機關(guān)閉，模擬門閘關(guān)閉狀態(tài)，并將溫度信息通過wifi模塊上傳至后臺，提醒后臺工作人員進行上報和處理。主模塊原理圖如下：
