本期為大家推送迪文科技校企合作案例——全自動(dòng)智能核酸提取儀。該方案具有直觀的操作界面，通過(guò)屏幕實(shí)時(shí)監(jiān)控設(shè)備狀態(tài)、溫度、時(shí)間等信息，可通過(guò)調(diào)整參數(shù)，并集成了紫外消毒、密碼修改等實(shí)用功能，增強(qiáng)了實(shí)驗(yàn)操作的便捷性與數(shù)據(jù)的安全性。同時(shí)，設(shè)備還支持實(shí)驗(yàn)啟動(dòng)、暫停及結(jié)束操作，以及HEAP和LED燈光控制，進(jìn)一步確保了實(shí)驗(yàn)的精確性與可靠性。

<主界面>：主要包括儀器主菜單選擇，HEAP系統(tǒng)（減少氣溶膠污染）、LED（照明）和實(shí)驗(yàn)選擇等。(圖1)

<設(shè)置>：核酸提取儀具體的儀器調(diào)試、參數(shù)設(shè)置等。（圖2）

<新建實(shí)驗(yàn)>：核酸提取儀工作運(yùn)行與工作參數(shù)配置。（圖3）

<紫外消毒>：核酸提取儀開(kāi)啟關(guān)閉紫外線燈滅菌及開(kāi)啟時(shí)間的設(shè)置等。（圖4）

< 登錄界面 >：通過(guò)輸入密碼解鎖使用權(quán)限。（圖5）

< 密碼修改界面 >：通過(guò)輸入舊密碼來(lái)更換成新密碼。（圖6）

【C51工程設(shè)計(jì)】

C51的代碼量較大，這里以主函數(shù)代碼及各種控件的處理代碼為例。

主函數(shù)：

#include "sys.h"

#include "uart4.h"

#include "uart5.h"

#include "touch.h"

#include "tim0.h"

#include "norflash.h"

#include "lab.h"

void main(void)

{  

    sys_init();

    uart4_init(9600);

    uart5_init(9600);

    timer0_cnt_init();

    page_change(25);

    touch_init();

    while(1)

    {   

        val_addr_handler();

        lab_time_handler();

        Uart4_Rx_handler();

    }  

}
