基於Wio Terminal的簡易智能家居中控系統(初代版本)

經過不斷地踩坑(學習),初代的簡易智能家居中控系統已經做好了,在申請項目時填寫的功能都做出來了,但是有些功能不是用Wio Terminal實現的(一方面是因爲代碼量太大,會給Wio Terminal的"壓力"也很大,另一方面,我的技術還不太夠,還要繼續學習、尋找解決方法)。

先給大家介紹一下我最初的想法

項目簡介

  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是一塊高度集成的開發板,它自帶一塊液晶顯示屏、三個按鈕、一個五向開關以及麥克風、揚聲器、加速度傳感器、紅外發射器等,它甚至可以和樹莓派、Jetson nano結合。而作爲一個家的"大腦",這些硬件都是非常實用的,因此,在智能家居中控系統中,我選擇將Wio Terminal作爲這個系統的核心。

  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!
  未來的家裏,應該有一個智能管家,這個智能管家就是我現在做的簡易版本。有了它,你便可以獲取家裏準確且實時的溫度、溼度、光照強度等數據。不僅如此,它還像一個"萬能"遙控器,能幫助你操控家裏的電器。當然,它應該像智能音箱一樣可以聽懂我們給它的指令,並給我們做出迴應!

系統功能

1. 在液晶顯示屏上展示溫溼度、光照強度、大氣壓力、可燃氣體含量等數據,爲了省電,當用戶拿起它時,該系統纔會顯示這些數據。
2. 控制燈的開關,左邊的按鈕能控制燈的開關,中間和右邊的按鈕分別能調亮和調暗。
3. 對該系統說話時,他會給用戶發送一個包含溫溼度、光照強度、大氣壓力、可燃氣體含量等數據的郵件。
4. 該系統會在用戶操控燈或是用語音操控其發送郵件時,會給予語音反饋。

前期準備

在做這個項目的過程中,我第一次使用Wio Terminal這一開發板:
給初次使用Wio Terminal的開發者的入門指南

不知道是什麼原因,我在Wio Terminal上使用Grove - Temperature Humidity Pressure Gas Sensor時收不到數據,以至於我不得不繞了彎去實現它:
使用Django搭建簡易數據中臺(基於Grove - Temperature Humidity Pressure Gas Sensor)

重新走回正軌,實現顯示數據的主要功能:
使用Wio Terminal通過HTTP請求獲取並展示傳感器實時數據

下一步就要完善其他三個功能了,這三個功能我主要通過Python實現

完善系統功能

前面我簡單提了一下某些不在Wio Terminal上實現的功能的原因,具體原因就不過多地闡述了,畢竟纔剛開始做,所以我打算先把功能實現了,至於實現方式,我想在二代系統中去改善

通過Wio Terminal輸出狀態

我想表達的狀態,是讀取Configurable Buttons的狀態(是否按下按鈕)和Microphone的數據 (數據也可以代表狀態)

對於Wio Terminal來說,單純地輸出這些數據是比較簡單的

在setup()裏補充引腳定義:

pinMode(WIO_MIC, INPUT);
pinMode(WIO_KEY_A, INPUT_PULLUP);
pinMode(WIO_KEY_B, INPUT_PULLUP);
pinMode(WIO_KEY_C, INPUT_PULLUP);

在loop()裏補充if條件語句:

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");
 }

當Wio Terminal連接PC端時,PC端會讀取串口的數據,讀到對應的輸出就做出相應的動作

成功上傳後,打開串口監視器:

下面,我們來看看Python的具體實現

使用Python讀取串口數據並做出相應決策

WEB端增加保存數據的功能

因爲需要發送郵件,所以我把傳感器接收到的數據先存放到一個txt文本文件裏,發送郵件時,直接發送這個文本文件即可

在views.py裏:

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)

主要改動的地方就是:

with open("D:\TemperatureHumidityPressureGasData.txt", "w") as fp:
        fp.write(jsonData)

文件存放的路徑可以修改成自己的路徑

打開該文本文件,看一下是否可以成功保存:

通過紅外模塊控制小夜燈

小夜燈是在某寶買的,可以用遙控器控制的那種:

因爲Wio Terminal沒有紅外解碼功能,所以我另外買了一個紅外模塊,編碼和解碼合在一起那種,當然還需要一個USB-TTL串口轉換器:

思路其實很簡單,讀取遙控器上對應按鍵發送的數據,再用紅外模塊發射出去即可

解碼可以用串口調試助手,比較方便:

串口收到什麼就發送什麼,接收的時候最好找個暗一點的地方,多試幾次

下面是我收集到的各個按鍵應該發送的數據(十六進制):

發送紅外只需要再加兩行即可:

send_data = bytes.fromhex(send_data) #先編碼,再發送
infrared_ser.write(send_data)

通過語音控制PC端發送郵件

語音這塊不是真正意義上的語音識別,當Wio Terminal識別到環境音頻信號有起伏時,會向串口發送"send message!",PC端讀取到後就會發送郵件

說話時,音頻信號會有明顯的起伏:

這裏的發送方和接收方都可以寫成自己的郵箱 ,試着發送一封郵件測試一下:

預覽一下這個txt文件:

通過語音合成給予用戶回覆

在Windows系統下,可以直接調用系統的語音包:

import win32com.client

speaker = win32com.client.Dispatch("SAPI.SpVoice")
text = "輸入要語音合成的內容"
speaker.Speak(text)

下面來看一下完整的程序

完整的程序

代碼裏的串口需要改成自己的串口 :

• COM14是Wio Terminal開發板
• COM15是紅外模塊
• COM19是Seeeduino V4.2開發板

每次插拔後,串口可能會發生改變,因爲電腦上的USB接口不夠用,我買了一個USB擴展塢

基於Wio Terminal的簡易智能家居中控系統

後期想法

  目前的系統只是非常簡易的初代版本,後期會考慮使用雲平臺來存儲傳感器收集的溫溼度、光照強度、紫外線強度等數據,並製作一個app,讓用戶出門在外也能對家裏的情況瞭如指掌。
