智能家居的話，如果只能手動(dòng)控制會(huì)覺(jué)得不太智能，如果能用說(shuō)的或者自動(dòng)的話體驗(yàn)可能會(huì)更好一些。

智能家居其實(shí)就是為了給生活添加一些便利，懶人推送科技發(fā)展是沒(méi)錯(cuò)的。

對(duì)于個(gè)人而言接入智能家居無(wú)非有以下幾個(gè)原因：

1、動(dòng)動(dòng)手動(dòng)動(dòng)嘴不動(dòng)腿就是懶恨不能意念控制

2、開(kāi)關(guān)對(duì)小朋友不友好，個(gè)頭不夠摸不到開(kāi)關(guān)

3、全屋聯(lián)動(dòng)回家模式離家模式等等

基于以上幾個(gè)原因

通過(guò)嘗試。實(shí)現(xiàn)了語(yǔ)音控制 HA 設(shè)備的基本功能。

主要思路如圖：

開(kāi)始想著增加機(jī)械開(kāi)關(guān)手動(dòng)去操作，后來(lái)想了以下都語(yǔ)音控制了還要物理開(kāi)關(guān)干嘛呢。

小朋友和老人，直接語(yǔ)音控制開(kāi)關(guān)設(shè)備。就很舒服呢。

對(duì)于紅外設(shè)備，還沒(méi)研究透徹怎么去獲取遙控器的紅外編碼，然后發(fā)射出來(lái)。這樣就可以實(shí)現(xiàn)更多的功能。

可以語(yǔ)音控制空調(diào)、電視等紅外設(shè)備。

[智能家居]MQTT 控制 HomeAssistant 設(shè)備

https://bbs.ai-thinker.com/forum.php?mod=viewthread&tid=44644&fromuid=15918

(出處: 物聯(lián)網(wǎng)開(kāi)發(fā)者社區(qū)-安信可論壇)

這里主要還是用到了 HomeAssistant 的自動(dòng)化功能，這種設(shè)置不需要對(duì) HomeAssistant 有很深的了解，簡(jiǎn)單配置即可。

對(duì)于小白用戶體驗(yàn)更好一些，上手就用。對(duì)于大佬的話，可以延伸出更多的功能。

下面介紹一下主要功能模塊

一、離線語(yǔ)音模組系列

VC 系列模組是我司開(kāi)發(fā)的一款 AI 離線語(yǔ)音識(shí)別的產(chǎn)品，主芯片是云知聲推出的離線語(yǔ)音識(shí)別芯片鋒鳥(niǎo) M(US516P6)，具有高可靠性，通用性強(qiáng)的特點(diǎn)。在語(yǔ)音識(shí)別技術(shù)上實(shí)現(xiàn)了高可靠的喚醒識(shí)別率、更遠(yuǎn)距離的喚醒、更低誤喚醒率、更強(qiáng)的抗噪音能力、更快的響應(yīng)識(shí)別時(shí)間，免聯(lián)網(wǎng)的純離線識(shí)別。

VC 系列模組采用了 32bit RISC 架構(gòu)內(nèi)核，并加入了專門(mén)針對(duì)信號(hào)處理和語(yǔ)音識(shí)別所需要的 DSP 指令集，支持浮點(diǎn)運(yùn)算的 FPU 運(yùn)算單元，以及 FFT 加速器。支持最高 150 條本地指令離線識(shí)別，支持 RTOS 輕量級(jí)系統(tǒng)，以及簡(jiǎn)單友好的客制化工具。

VC 系列模組具有豐富的外圍接口，包括 UART/I2C/PWM/SPI，以及簡(jiǎn)單友好的二次開(kāi)發(fā)工具,方便客戶實(shí)現(xiàn)單模組的語(yǔ)音控制應(yīng)用場(chǎng)景方案。

VC-02 模組

串口燒錄工具

定制語(yǔ)音

安信可語(yǔ)音開(kāi)放平臺(tái)：http://voice.ai-thinker.com/

在安信可語(yǔ)音開(kāi)放平臺(tái)創(chuàng)建產(chǎn)品，選擇 VC 系列模組。

然后修改喚醒詞

設(shè)置 Pin 引腳功能

波特率設(shè)置 115200，引腳 B6 設(shè)置為 UART1_RX 引腳 B7 設(shè)置為 UART1_TX,用來(lái)發(fā)送接收數(shù)據(jù)。注意不要配置多個(gè) UART1，否則不生效。

添加語(yǔ)音指令

然后添加控制詳情

這里主要用到的就是串口數(shù)據(jù)，這里發(fā)送指令 第一位是指令開(kāi)頭默認(rèn) A1，第二位定義的是設(shè)備位置，第三位定義的是設(shè)備類型，第四位定義的是開(kāi)關(guān)狀態(tài)，第五位結(jié)束位默認(rèn) FF。根據(jù)自己的需要設(shè)置解析即可。

還有免喚醒命令，不用喚醒詞直接就可以用，比如開(kāi)燈、關(guān)燈等等。

免喚醒命令詞最多 10 個(gè)選擇自己需要的添加，添多了也是默認(rèn)取前 10 條。

二、Ai-M61-32S Wi-Fi 模組

Ai-M61 系列模組（下稱模組）是由深圳市安信可科技有限公司開(kāi)發(fā)的 Wi-Fi6 & 藍(lán)牙雙模模組，搭載 BL618 芯片作為處理器，支持 Wi-Fi 802.11b/g/n/ax 協(xié)議和 BLE 5.3 協(xié)議。BL618 芯片內(nèi)置低功耗的 32 位 RISC-V CPU，最高主頻可達(dá) 320M. 豐富的外圍接口，包括 DVP、MJPEG、Dispaly、Audio Codec、USB2.0、SDU、以太網(wǎng)(EMAC)、SD/MMC(SDH)、SPI、UART、I2C、I2S、PWM、GPDAC、GPADC、ACOMP 和 GPIO 等。可廣泛應(yīng)用于音視頻多媒體、物聯(lián)網(wǎng)(IoT)、移動(dòng)設(shè)備、可穿戴電子設(shè)備、智能家居等領(lǐng)域。
