[Guardian] the Smart-Home-System

Overview

The Smart-Home-System is an open source project for multi-functional home monitoring system. It works mainly works as an server with other environment sensors . Users can do either remote monitoring, wireless control and automatic door control in maximums 24 clients(android and java desktop as examples inside the project) simultaneously.

Project structure

Android is the Android application client

DesktopClinet is a simple Java desktop client example based on Swing

PrototypeTest is some prototype when we try some new ideas

Application is the main logic server running on Raspberry PI (T means self contained thread):

Features

Basic

• Indoor gas status monitoring
• Remote video monitoring with face detection
• Remote door control
• Automatic door control by face detection and temperature measurement

Advanced

thanks to the independent structure of the server users can get information of server by their own defined clients. One can get massages by TCP socket:

• Send 4 byte int 0xff to the video server to get video frame in int frame_size followed with byte[frame_size] frame_data_incoded_with_jpeg
• Send 4 byte int 0x11 to the universal server to get home temperature in int actual_temperature_in cetigrade*1000
• Send 4 byte int 0x12 to the universal server to get home humidity in int actual_humidity_in_percent*1000
• Send 4 byte int 0x13 to the universal server to get home gas pressure in int actual_gas_pressure_in_P*1000
• Send 4 byte int 0x15 to the universal server to open the door
• Send 4 byte int 0x16 to the universal server to get door status in int status, if status > 0 means door is opened, status = 0 means door is closed.

Installation

Hardware

• SG90 : Servo
• BME680: gas sensor
• AMG8833: thermal sensor
• Raspberry Pi 3 Model B
• Camera: image capturer

The GPIO point of Raspberry is list below, remember we are using BCM port number:

Here we use power of 5v, and v- as 0V.

The BME680 and AMG8833 is connected in series I2C with any SDA and SCL pin.

The servo can be connected to any GPIO port.

Software

Firstly install CMake, the minimum make version is 3.12.4

Then, download and install all CPP libraries listed below:

• pigpio
• opencv4.x
• boost

important: please using make install to install all libraries and include headers to your /usr/lib and /usr/include directory, if you want to specify your own library and headers' directory, please modify the Application/CmakeLists.txt file.

Then, make sure you've installed python3.7, here we recommend anaconda

Then, install python packages as root by typing:

sudo pip3 install adafruit_amg88xx
sudo pip3 install bme680

Then, you need check the connectivity of hardware, find the i2c address of bme680 and amg8833, in raspberry pi, you may check it by typing:

sudo i2cdetect -y 1

change the settings in Application/main_def.hpp:

#define LOCKER_SERVO_PIN 17   //lock servo port
#define VIDEO_SERVER_PORT 12345 //video server port
#define UNIVERSAL_SERVER_PORT 1148 // universal server port
#define AMG8833_ADDR 0x69 //amg8833 i2c address
#define BME680_ADDR 0x77 //bme680 i2c address

now you can start your build:

cd Application/build
cmake ..
make

if succeed, you can execute the application by

sudo ./VideoStream

all unit tests can be run in Application/build/tests/ folder.
