微信小程序+OneNET物联+掌控板
本帖最后由 云天 于 2019-12-5 22:32 编辑要实现，通过微信小程序语音控制掌控板。语音识别可通过微信小程序中加载官方推出微信同声传译插件实现。在掌控板上亮灯及显示相应控制指令。
https://www.dfrobot.com.cn/images/upload/Image/20190621154900y29j5q.jpg暂未控制电机，因发现mPython X不能使用掌控板扩展板（也许是自己不会用，请各位指教）。那么如何使用该款插件呢？开发者可登录小程序后台管理，依次选择【设置】【第三方服务】【添加插件】输入“同声传译”或者“语音识别”、“翻译”等搜索关键字搜索插件即可添加。

只要你添加了该款插件，便能利用该插件开放的语音识别接口、语音合成接口、文本翻译接口实现小程序的语音功能。
1、index.js中代码
//index.js
//获取应用实例
const app = getApp()
Page({
data: {
button:'语音识别',
tts:''
},
//事件处理函数
OneNet: function (ml) {//向掌控板下发命令
wx.request({
url: 'https://api.heclouds.com/cmds?device_id=566544929', //接口地址，自己设备ID
header: {
'api-key': 'wVCSX14SwmBSuS=DIU2M=eHqVb0=' // 填写自己设备ID的'api-key'
},
method: 'POST',
data: ml,
success(res) {
console.log(res.data)
}
})
},
tts:function(){
var that = this;
if(that.data.button==="语音识别"){
that.setData({
button: "退出语音"
});
var plugin = requirePlugin("WechatSI")//在app.json中加载“微信同声传译”插件
let manager = plugin.getRecordRecognitionManager()
manager.onRecognize = function (res) {//语音识别过程中，判断是否出现控制指令，如“向左”
console.log("current result", res.result)
if (res.result != "" || res.result !=NULL){
if(res.result.indexOf("向左")!=-1){//下达控制指令时，可以使用如“向左转”、“向前进”等，增加识别率
that.setData({
tts: "向左"
});
that.OneNet("向左");
manager.stop();
}
if (res.result.indexOf("向右") != -1) {
that.setData({
tts: "向右"
});
that.OneNet("向右");
manager.stop();
}
if (res.result.indexOf("前进") != -1) {
that.setData({
tts: "前进"
});
that.OneNet("前进");
manager.stop();
}
if (res.result.indexOf("后退") != -1) {
that.setData({
tts: "后退"
});
that.OneNet("后退");
manager.stop();
}
if (res.result.indexOf("停止") != -1) {
that.setData({
tts: "停止"
});
that.OneNet("停止");
manager.stop();
}
if (res.result.indexOf("退出") != -1) {
that.setData({
tts: "退出"
});
manager.stop();
}
}
}
manager.onStop = function (res) {//在识别完成时，判断是退出还是进行下一次语音识别，这样可连续识别，也可通过“退出”指令结束语音识别。
console.log("record file path", res.tempFilePath);
console.log("result", res.result)
if (res.result != "" || res.result != NULL) {
if (res.result.indexOf("退出")===-1){
manager.start({ duration: 30000, lang: "zh_CN" })
}
else{
that.setData({
button: "语音识别"
});
}
}
else{
manager.start({ duration: 30000, lang: "zh_CN" })
}
}
manager.onStart = function (res) {
console.log("成功开始录音识别", res)
}
manager.onError = function (res) {
console.error("error msg", res.msg)
manager.start({ duration: 30000, lang: "zh_CN" })
}
manager.start({ duration: 30000, lang: "zh_CN" })
}
else {
that.setData({
button: "语音识别"
});
}
}
})
2、页面布局
<!--index.wxml-->
<view class="container">
<view class="userinfo">
<text class="user-motto">语音结果：{{tts}}</text>
</view>
<view class="usermotto">
<button bindtap="tts"> {{button}} </button>
</view>
</view>
3、插件加载，app.json
{
"pages": [
"pages/index/index",
"pages/logs/logs"
],
"window": {
"backgroundTextStyle": "light",
"navigationBarBackgroundColor": "#fff",
"navigationBarTitleText": "小程序语音控制掌控板",
"navigationBarTextStyle": "black"
},
"style": "v2",
"sitemapLocation": "sitemap.json",
"plugins": {
"WechatSI": {
"version": "0.0.7",
"provider": "wx069ba97219f66d99"
}
}
}

很棒的文章 X还不支持DF的扩展板，你懂的。
不过mpython将来会开放接口，高手自己写就可以了。{:5_178:} 如果电机不用控制转速，可以直接接到引脚上，前几天做远程控制风扇就是直接接到引脚上的 支持一下
