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

一 概述

DO 即模擬輸入（AI, Analog Input），用于讀取連續(xù)變化的信號(hào)，如溫度、濕度、壓力等。模擬輸入可以接收一定范圍內(nèi)的電壓或電流信號(hào)，并將其轉(zhuǎn)換為數(shù)字值。

二 相關(guān)技術(shù)描述

采集 4-20mA（可選 0-5V）信號(hào)。下圖為一種硬件設(shè)計(jì)方案

一般儀器儀表的信號(hào)電流都為4mA-20mA，指最小電流為4mA,最大電流為20mA 。

傳輸信號(hào)時(shí)候，要考慮到導(dǎo)線上也有電阻，如果用電壓傳輸則會(huì)在導(dǎo)線的產(chǎn)生一定的壓降，那接收端的信號(hào)就會(huì)產(chǎn)生一定的誤差了！所以使用電流信號(hào)作為變送器的標(biāo)準(zhǔn)傳輸！

那么為什么選擇4mA-20mA而不是0mA-20mA呢？4ma而不是0ma是用來檢測(cè)線路開路的，如果0是最小，那么開路故障就檢測(cè)不到了

可將采集值轉(zhuǎn)換為實(shí)際測(cè)量值，支持校準(zhǔn)?

可設(shè)置多項(xiàng)采樣、報(bào)警（如設(shè)置上下限報(bào)警值）

與數(shù)據(jù)上報(bào)參數(shù)?

支持連接及斷開狀態(tài)檢測(cè)?

雙重?cái)?shù)字濾波器抗噪?

采樣頻率：33Hz

采樣頻率（Sampling Frequency）是指在單位時(shí)間內(nèi)從連續(xù)信號(hào)中提取并組成離散信號(hào)的采樣個(gè)數(shù)，通常用赫茲（Hz）來表示。它是數(shù)字信號(hào)處理中的一個(gè)重要概念，用于將模擬信號(hào)轉(zhuǎn)換為數(shù)字信號(hào)。

10 位精度

10位ad轉(zhuǎn)換就是把模擬信號(hào)比如5v的電壓轉(zhuǎn)換成10位的數(shù)字信號(hào)1111111111.來表示.那么0v的模擬信號(hào)用數(shù)字量表示就是0000000000.精度其實(shí)就是分辨率即指數(shù)字量變化一個(gè)最小量時(shí)模擬信號(hào)的變化量.所以這里的精度應(yīng)該是5/2^10

三 應(yīng)用場(chǎng)景

3.1 水泵

云端通過控制DO輸出高低電平，來控制外圍電路，進(jìn)而控制水泵的啟停。

3.2 風(fēng)扇

同理，云端通過控制DO輸出高低電平，來控制外圍電路，進(jìn)而控制風(fēng)扇的啟停。

3.3 報(bào)警燈

結(jié)合DTU的DI功能，如果檢測(cè)到了DI異常信號(hào)輸入，DTU可以控制連接DO的報(bào)警燈報(bào)警。

4 Demo實(shí)戰(zhàn)

4.1 創(chuàng)建一個(gè)Demo

復(fù)制20.9_di_xtu示例工程，到同一個(gè)文件夾下，修改文件名為20.11_ai_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_sdksamplelibraries20.11_ai_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，

根據(jù)實(shí)驗(yàn)現(xiàn)象，用戶需要實(shí)現(xiàn)自己的AT指令，只需要參考組件中的例子，按照自己需求修改，

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(cè)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~~
