C#+Arduino Uno 实现声控系统完全实施手册

2022-05-23 05:00:39

话不多说先上视频，一看就懂

另外可参考这里:https://www.cnblogs.com/dehai/p/4285749.html ，这个近6年前的帖子

程序结构

程序分成上位机(PC端）与下位机（单片机）:

PC端，使用的是WinForm ,声音识别采用微软的System.Speech.dll（这个也有很多坑后面会每坑说明）

程序由：指令库，任务库，Http服务3部分组成

指令库:
系统会选择加载目录下XH.Cmd.xxxx.dll文件，并加载XHCmd开头的类型，类型需要做XHCmdAttribute标注，并且继承XHCommandBasic类

任务库:
系统会选择加载目录下XH.Task.xxxx.dll文件,并且加载XHTask开头的定义且继承XHTaskBasic的类，这可以用来提醒下班，自动关灯，关空调

定期检查机房服务器状态等等。。。。可以做很多扩展。

可以在在配置文件AppSetting节中ExcludeCmd与ExcludeTask，排除不需要加载的类型，另外下班提醒时间，开灯开空调提醒域值也在配置文件中

下面是PC端需要注意的问题---各种坑点

1.操作系统用的是Win7 64位完整版，很多Ghost版不带语音模块，程序能编译但一运行就会出错

2.电脑的麦克风跟杨声器最好是2个设备并且分开一段距离防

3.无法把程序改成Windows服务的形式，必需是可视化的Windows Form形式，远程桌面连接或计划任务启动的都无法使用语音识别功能

如果要长期处于监听状态，只能将程序执行文件的快捷方式拖进Windows的 “启动”目录下，并且取消windows的登陆界面

4.为保证程序稳定运行，建议在计划任务里设置每天凌晨重启PC、

5.当然为了保证一定的安全，PC机专用，开启防火墙（但要开放TCP ,9495端口），另外可以在网关设备或核心交换机处禁止PC访问外网或被外网访问。

6.提供的代码里定义PC的IP是10.2.8.188，端口是9495, 使用时务必修改成实际的IP地址

7.app.Config中的DefaultClientIP用来区分多个单片机用的，目前只涉及一个单片机的情况下设置成服务器IP:Port形式，如果要支持多个单片机，需要自己调整程序，框架是支持的。

具体原理是，单片机每个http请求会在QueryString携带传感器读数，并且带上自己的标识(也就是TagIP), 而PC会将下发的指令（指开灯，开空调等）通过这个请求的Response 返回给

指定tagIp的单片机，下发指令存放在一个以tagIp作为key的字典中。收到http请求后，在生成Response时会查看对应Key的字典中有无要携带回去的指令，有的话就会在Response中体现。每个单片机每隔2-3秒左右发送一次请求，也就是系统延迟在2-3秒左右。

8.执行目录下的data下面可以放mp3，语音指令是”播放音乐“，程序会随机选择一个mp3文件播放。

单片机是arduino uno 配合网络板扩展，采用的是有线网络，硬件模块也是近6年前的老物件

单片上连了红外头用来控制空调，光敏电阻采集网照强度可以在昏暗时提醒开灯，用温湿传感器DHT11--这个也比较坑，用电流传感器--用来确定空调是否打开，还有控制灯的继电器

完整的单片机代码入下，注意接口

#define DHT11_PIN 0 ---dht11 连的是arduino的A0 口
#define CurrentIndexPin A3 --- 电流传感器连A3口
#define IlluminationPin A2 --热敏电阻连A2口
#define relayAPin 8 ---继电器连 8号口
#define RebootPin 5 --这个是5号口连的是三级管的基级，用来物理重启单片机用的，这样你的系统可以非常非常强壮
