物聯(lián)網(wǎng)中RTU的DI是什么？如何實(shí)現(xiàn)DI相關(guān)軟件功能？

一 概述

DI即數(shù)字輸入（DI, Digital Input），用于接收二進(jìn)制信號(hào)（0或1），通常用于接收開關(guān)、按鈕、傳感器（如接近開關(guān)、光電傳感器等）的狀態(tài)。數(shù)字輸入只能識(shí)別兩種狀態(tài)：高電平（通常代表“1”或“開”）和低電平（通常代表“0”或“關(guān)”）。

二 相關(guān)技術(shù)描述

常開觸點(diǎn)（NO）或常閉觸點(diǎn)（NC）接入，

常開觸點(diǎn)，也稱為NO（Normally Open）觸點(diǎn)，指的是一種當(dāng)電氣設(shè)備未被激活時(shí)處于打開狀態(tài)的開關(guān)。換句話說，當(dāng)電流通過該開關(guān)時(shí)，觸點(diǎn)會(huì)關(guān)閉并允許電流流動(dòng)；而當(dāng)電流停止流動(dòng)時(shí)，觸點(diǎn)會(huì)自動(dòng)返回到打開狀態(tài)。常開觸點(diǎn)通常被用于需要手動(dòng)控制的電路中，例如呼叫按鈕、燈開關(guān)等。

常閉觸點(diǎn)，也稱為NC（Normally Closed）觸點(diǎn)，指的是一種當(dāng)電氣設(shè)備未被激活時(shí)處于關(guān)閉狀態(tài)的開關(guān)。與常開觸點(diǎn)不同，當(dāng)電流通過該開關(guān)時(shí)，觸點(diǎn)會(huì)打開并中斷電流的流動(dòng)；而當(dāng)電流停止流動(dòng)時(shí)，觸點(diǎn)會(huì)自動(dòng)返回到關(guān)閉狀態(tài)。常閉觸點(diǎn)通常被用于需要自動(dòng)控制的電路中，例如安全繼電器、保護(hù)裝置等。

狀態(tài)觸發(fā)? 可配置為脈沖計(jì)數(shù)接口

一種上升沿（按鍵釋放計(jì)數(shù)），一種下降沿（按鍵閉合計(jì)數(shù)），第三種電平（按鍵閉合釋放都會(huì)計(jì)數(shù)）。

濾波參數(shù)用于輸入信號(hào)有效性判斷，比如默認(rèn)使用6即6ms以下的輸入信號(hào)作為抖動(dòng)不會(huì)進(jìn)行計(jì)數(shù)也不會(huì)判斷為有效的輸入信號(hào)。

干節(jié)點(diǎn)信號(hào)輸入或0～3.3V電平信號(hào)輸入?

干接點(diǎn)信號(hào)是一種電氣開關(guān)信號(hào)，具有閉合和斷開兩種狀態(tài)，其兩個(gè)接點(diǎn)之間沒有極性，可以互換。這種信號(hào)通常用于各種開關(guān)、傳感器輸出以及繼電器、干簧管的輸出等。干接點(diǎn)信號(hào)在工業(yè)控制領(lǐng)域中應(yīng)用廣泛，具有無需電源即可工作的特點(diǎn)，適用于多種設(shè)備和場景。

三 應(yīng)用場景

3.1 計(jì)數(shù)器

統(tǒng)計(jì)接入設(shè)備觸發(fā)的次數(shù)，涉及到DI的采樣頻率，頻率太高，可能漏采，這一點(diǎn)在使用時(shí)必須考慮

3.2 門磁

門磁開關(guān)常用于門是否開啟、關(guān)閉。兩個(gè)磁鐵靠近后會(huì)產(chǎn)生一個(gè)高電平，或者低電平信號(hào)，DI檢測到后，可以識(shí)別門的狀態(tài)，從而通知云端同步門的狀態(tài)

3.3 紅外感應(yīng)

常用于熱源檢測，例如是否有人進(jìn)入檢測等。檢測到熱源后，會(huì)產(chǎn)生一個(gè)高電平或者低電平信號(hào)，DI接收到后，通知遠(yuǎn)端檢測事件發(fā)生。

3.4 煙感

室內(nèi)防火使用，檢測到煙以后，DI檢測到，配合DTU輸出DO告警等。

3.5 水浸

檢測是否有水進(jìn)入，傳感器會(huì)產(chǎn)生數(shù)字輸出信號(hào)給DI，DI檢測到后，進(jìn)行下一步處理。

4 Demo實(shí)戰(zhàn)

4.1 創(chuàng)建一個(gè)Demo

復(fù)制20.2_at_xtu示例工程，到同一個(gè)文件夾下，修改文件名為20.9_di_xtu，如圖：

4.2 修改makefile

增加文件組件所在目錄頭文件路徑，和源文件路徑，以及一些宏定義，如圖：

-D是makefile中定義宏定義必要的前綴，可以搜索相關(guān)makefile學(xué)習(xí)文章學(xué)習(xí)相關(guān)知識(shí)。

DTU_BASED_ON_TCP 表示當(dāng)前是TCP模式，當(dāng)前組件使用需要am.h中包含一些對(duì)應(yīng)。

DTU_TYPE_5X6 表示使用SOM板貼片5x6卡，可以使用其它卡，修改為對(duì)應(yīng)宏定義就可以。

DTU_UART_115200_BAUD 表示使用115200波特率

DTU_TYPE_JSON_INCLUDE 表示把JSON功能包含進(jìn)來

4.3 增加頭文件

使用代碼編輯器，將新建的工程文件加入代碼編輯器中，打開main.c，修改main.c，加入am.h頭文件，如圖：

4.4 修改代碼

示例使用的是板載5x6卡，用戶的硬件可能是使用外置卡，或者是三合一全網(wǎng)通卡，因?yàn)橛布先N卡使用的模組SIM卡接口不一樣（外置卡SIM1，5x6卡和三合一卡SIM2），所以，需要通過一個(gè)全局變量來制定SIM卡硬件接口。

extern外部變量SDK_INIT_SIM_SELECT_VALUE，這里判斷了是否使用外置卡，這個(gè)宏定義在Makefile里面定義。

在Phase1Inits_enter中，宏定義判斷是否要包含對(duì)SDK_INIT_SIM_SELECT_VALUE變量的修改。

在Phase2Inits_exit 調(diào)用文件組件提供的對(duì)外API，如圖：

4.5 編譯

在SDK根目錄打開命令行，輸入命令.build.bat -l .amaziot_bloom_os_sdksamplelibraries20.9_di_xtu

4.6 生成固件

參考入門中開發(fā)工具，生成工具。

4.7 查看現(xiàn)象

固件下載到模組后，發(fā)送DI 配置AT指令，觀察AT串口信息，

觸發(fā)di后，使用查看命令

本文章源自奇跡物聯(lián)開源的物聯(lián)網(wǎng)應(yīng)用知識(shí)庫Cellular IoT Wiki，更多技術(shù)干貨歡迎關(guān)注收藏Wiki：Cellular IoT Wiki 知識(shí)庫（https://rckrv97mzx.feishu.cn/wiki/wikcnBvAC9WOkEYG5CLqGwm6PHf）

歡迎同學(xué)們走進(jìn)AmazIOT知識(shí)庫的世界！

這里是為物聯(lián)網(wǎng)人構(gòu)建的技術(shù)應(yīng)用百科，以便幫助你更快更簡單的開發(fā)物聯(lián)網(wǎng)產(chǎn)品。

Cellular IoT Wiki初心：

在我們長期投身于蜂窩物聯(lián)網(wǎng) ODM/OEM 解決方案的實(shí)踐過程中，一直被物聯(lián)網(wǎng)技術(shù)碎片化與產(chǎn)業(yè)資源碎片化的問題所困擾。從產(chǎn)品定義、芯片選型，到軟硬件研發(fā)和測試，物聯(lián)網(wǎng)技術(shù)的碎片化以及產(chǎn)業(yè)資源的碎片化，始終對(duì)團(tuán)隊(duì)的產(chǎn)品開發(fā)交付質(zhì)量和效率形成制約。為了減少因物聯(lián)網(wǎng)碎片化而帶來的重復(fù)開發(fā)工作，我們著手對(duì)物聯(lián)網(wǎng)開發(fā)中高頻應(yīng)用的技術(shù)知識(shí)進(jìn)行沉淀管理，并基于 Bloom OS 搭建了不同平臺(tái)的 RTOS 應(yīng)用生態(tài)。后來我們發(fā)現(xiàn)，很多物聯(lián)網(wǎng)產(chǎn)品開發(fā)團(tuán)隊(duì)都面臨著相似的困擾，于是，我們決定向全體物聯(lián)網(wǎng)行業(yè)開發(fā)者開放奇跡物聯(lián)內(nèi)部沉淀的應(yīng)用技術(shù)知識(shí)庫 Wiki，期望能為更多物聯(lián)網(wǎng)產(chǎn)品開發(fā)者減輕一些重復(fù)造輪子的負(fù)擔(dān)。

Cellular IoT Wiki沉淀的技術(shù)內(nèi)容方向如下：

奇跡物聯(lián)的業(yè)務(wù)服務(wù)范圍：基于自研的NB-IoT、Cat1、Cat4等物聯(lián)網(wǎng)模組，為客戶物聯(lián)網(wǎng)ODM/OEM解決方案服務(wù)。我們的研發(fā)技術(shù)中心在石家莊，PCBA生產(chǎn)基地分布在深圳、石家莊、北京三個(gè)工廠，滿足不同區(qū)域&不同量產(chǎn)規(guī)模&不同產(chǎn)品開發(fā)階段的生產(chǎn)制造任務(wù)。跟傳統(tǒng)PCBA工廠最大的區(qū)別是我們只服務(wù)物聯(lián)網(wǎng)行業(yè)客戶。

連接我們，和10000+物聯(lián)網(wǎng)開發(fā)者一起 降低技術(shù)和成本門檻

讓蜂窩物聯(lián)網(wǎng)應(yīng)用更簡單~~
