经过不断地踩坑(学习),初代的简易智能家居中控系统已经做好了,在申请项目时填写的功能都做出来了,但是有些功能不是用Wio Terminal实现的(一方面是因为代码量太大,会给Wio Terminal的"压力"也很大,另一方面,我的技术还不太够,还要继续学习、寻找解决方法)。
先给大家介绍一下我最初的想法
项目简介
Wio Terminal is a highly integrated development board, which comes with an LCD display, three buttons, a five-way switch, as well as microphones, speakers, accelerometers, infrared transmitters, etc., it can even be combined with the Raspberry Pi, Jetson nano! As the “brain” of a home, these hardware are extremely practical, therefore, in the smart home control system, I choose Wio Terminal as the core of this system.
Wio Terminal是一块高度集成的开发板,它自带一块液晶显示屏、三个按钮、一个五向开关以及麦克风、扬声器、加速度传感器、红外发射器等,它甚至可以和树莓派、Jetson nano结合。而作为一个家的"大脑",这些硬件都是非常实用的,因此,在智能家居中控系统中,我选择将Wio Terminal作为这个系统的核心。
In the future, there should be a smart housekeeper in the house, and this smart housekeeper is a simple version of what I am doing now. With it, you will be able to get accurate and real-time data of temperature, humidity, light intensity and so on. Not only that, it’s also like a “universal” remote control which can help you control your home’s appliances. Of course, it should be like a smart speaker can understand our instructions, and give us a response!
未来的家里,应该有一个智能管家,这个智能管家就是我现在做的简易版本。有了它,你便可以获取家里准确且实时的温度、湿度、光照强度等数据。不仅如此,它还像一个"万能"遥控器,能帮助你操控家里的电器。当然,它应该像智能音箱一样可以听懂我们给它的指令,并给我们做出回应!
系统功能
- 在液晶显示屏上展示温湿度、光照强度、大气压力、可燃气体含量等数据,为了省电,当用户拿起它时,该系统才会显示这些数据。
- 控制灯的开关,左边的按钮能控制灯的开关,中间和右边的按钮分别能调亮和调暗。
- 对该系统说话时,他会给用户发送一个包含温湿度、光照强度、大气压力、可燃气体含量等数据的邮件。
- 该系统会在用户操控灯或是用语音操控其发送邮件时,会给予语音反馈。
前期准备
在做这个项目的过程中,我第一次使用Wio Terminal这一开发板:
给初次使用Wio Terminal的开发者的入门指南
不知道是什么原因,我在Wio Terminal上使用Grove - Temperature Humidity Pressure Gas Sensor时收不到数据,以至于我不得不绕了弯去实现它:
使用Django搭建简易数据中台(基于Grove - Temperature Humidity Pressure Gas Sensor)
重新走回正轨,实现显示数据的主要功能:
使用Wio Terminal通过HTTP请求获取并展示传感器实时数据
下一步就要完善其他三个功能了,这三个功能我主要通过Python实现
完善系统功能
前面我简单提了一下某些不在Wio Terminal上实现的功能的原因,具体原因就不过多地阐述了,毕竟才刚开始做,所以我打算先把功能实现了,至于实现方式,我想在二代系统中去改善
通过Wio Terminal输出状态
我想表达的状态,是读取Configurable Buttons的状态(是否按下按钮)和Microphone的数据 (数据也可以代表状态)
对于Wio Terminal来说,单纯地输出这些数据是比较简单的
在setup()里补充引脚定义:
pinMode(WIO_MIC, INPUT);
pinMode(WIO_KEY_A, INPUT_PULLUP);
pinMode(WIO_KEY_B, INPUT_PULLUP);
pinMode(WIO_KEY_C, INPUT_PULLUP);
在loop()里补充if条件语句:
int val_first = analogRead(WIO_MIC);
int val_next = analogRead(WIO_MIC);
if (abs(val_first - val_next) >= 100){
Serial.println("send message!");
}
if (digitalRead(WIO_KEY_A) == LOW) {
Serial.println("A Key pressed");
}
if (digitalRead(WIO_KEY_B) == LOW) {
Serial.println("B Key pressed");
}
if (digitalRead(WIO_KEY_C) == LOW) {
Serial.println("C Key pressed");
}
当Wio Terminal连接PC端时,PC端会读取串口的数据,读到对应的输出就做出相应的动作

成功上传后,打开串口监视器:
下面,我们来看看Python的具体实现
使用Python读取串口数据并做出相应决策
WEB端增加保存数据的功能
因为需要发送邮件,所以我把传感器接收到的数据先存放到一个txt文本文件里,发送邮件时,直接发送这个文本文件即可
在views.py里:
def index(request):
datas = getDatas()
content = {
'temperature':datas[0],
'pressure':datas[1],
'humidity':datas[2],
'gas':datas[3],
'updataTime':datas[4],
}
jsonData = json.dumps(content)
with open("D:\TemperatureHumidityPressureGasData.txt", "w") as fp:
fp.write(jsonData)
return HttpResponse(jsonData)
主要改动的地方就是:
with open("D:\TemperatureHumidityPressureGasData.txt", "w") as fp:
fp.write(jsonData)
文件存放的路径可以修改成自己的路径
打开该文本文件,看一下是否可以成功保存:
通过红外模块控制小夜灯
小夜灯是在某宝买的,可以用遥控器控制的那种:
因为Wio Terminal没有红外解码功能,所以我另外买了一个红外模块,编码和解码合在一起那种,当然还需要一个USB-TTL串口转换器:
思路其实很简单,读取遥控器上对应按键发送的数据,再用红外模块发射出去即可
解码可以用串口调试助手,比较方便:
串口收到什么就发送什么,接收的时候最好找个暗一点的地方,多试几次
下面是我收集到的各个按键应该发送的数据(十六进制):

发送红外只需要再加两行即可:
send_data = bytes.fromhex(send_data) #先编码,再发送
infrared_ser.write(send_data)
通过语音控制PC端发送邮件
语音这块不是真正意义上的语音识别,当Wio Terminal识别到环境音频信号有起伏时,会向串口发送"send message!",PC端读取到后就会发送邮件
说话时,音频信号会有明显的起伏:
发送邮件不难,我把他封装成了一个方法 ,用到时直接调用即可:

这里的发送方和接收方都可以写成自己的邮箱 ,试着发送一封邮件测试一下:
预览一下这个txt文件:
通过语音合成给予用户回复
在Windows系统下,可以直接调用系统的语音包:

下面来看一下完整的程序
完整的程序
代码里的串口需要改成自己的串口 :
- COM14是Wio Terminal开发板
- COM15是红外模块
- COM19是Seeeduino V4.2开发板
每次插拔后,串口可能会发生改变,因为电脑上的USB接口不够用,我买了一个USB扩展坞

项目展示
基于Wio Terminal的简易智能家居中控系统
后期想法
目前的系统只是非常简易的初代版本,后期会考虑使用云平台来存储传感器收集的温湿度、光照强度、紫外线强度等数据,并制作一个app,让用户出门在外也能对家里的情况了如指掌。
