The subject of my presentation is SMART HOUSE.
I think this topic is very important for the audience because it is connected with our future life.
The main points of my talk are:
The History of the development of «Smart House»
The work of the home automation system
Sensors in the clever house
My talk will be during 10 minutes.
At the end of our talk I’ll answer you questions.
First of all I’ll be looking at the history of smart house.
One of the first "Smart Houses" was built in the United States of America. It happened in the middle of the XX century. They were houses of the wealthiest Americans, equipped with electronics, such as microwave, washing machine, air conditioner, fan or wall-mounted TV with a remote control system.
History of "smart home" began in 1961, when Joel and Ruth Spira invented and patented a special device for fine adjustment of light.
A major event in the further development of technology "smart home" was the creation of the Swedish company Pico Electronics, home automation in 1975, which first began to be used to control the music player.
In 1978 was developed a technology management of electrical household appliances by wire network. It was done by the company Leviton and X10 USA. But this technology is anticipated frequency of 60 Hz and a voltage of 110 V, because of what was not popular in Russia.
Company Echelon, created protocol LonWorks, allowed intellectualize each node management system and microprocessor chips. This system allows you to store the database parameters and data on scanning the various devices on the computer, and after the commission of certain events happening any reaction to these events.
Now days the system went even further in terms of features.
This leads directly to the next part of my talk. I would like to tell you about the application of home automation in peoples’ practice
Twitter & SMS Doorbell
If someone pressing the doorbell an X10 signal to Misterhouse which announces the speakers that there is someone at the door and sent an sms text message toy mobile phone.
Turning lights on and off
in several areas will turn lights detecting movement if it is dark. In the morning it turns bedside light on to wake somebody up gradually.
A Voice message.
Voice message telling me what time it is, what the external temperature is and the current weather. The system also provides notifications if the fridge door has been left open.
The coffee machine
The coffee machine in the kitchen is turned on a few minutes after Star Trek sounds that coffee is ready.
People can schedule events creating an event in a Google calendar which makes a nice easy way to schedule things from any device and caters for one off events or repeating events.
Monitoring of gas usage
Monitoring of gas usage has a pulse magnet inside that pulses and show how much gas is used.
The central heating thermostat
The central heating thermostat can control the heating based on the temperature information.
Video system may consists of three IP cameras. For examples: Camera one is opposite down the front path from above the front door. Camera 2 is inside the front window. Camera 3 with night vision gives a view of the yard and back door.
People used external Pace Voice modem later they switched to Asterisk. Asterisk is very powerful and has huge potential for home automation. Such as music, call parking, speaking clock, alarm calls and so on.
An autonomous robotic vacuum cleaner, on a preset schedule it will set off and clean the living area returning to its charger once finished.
Curtain Automation automate opening and closing of the living room curtains.
Next I’ll go on to the examples of sensors home automation system.
The sensors tracing the movement
They applied in security systems and in creation of intellectual lighting.
Gerkon is the electromechanical device, working at disconnection of contacts.
The acoustic announcer of breaking glass reacts to a sound at glass destruction.
Motion sensors are based on technology of tracking change infrared or ultrasonic fields, they are used in security systems and automatic managements lighting .
Sensors of presence are similar to sensors of the movement. They are based on the principle of action, but are more sensitive to change of parameters.
The sensors reacting to environment parameters
The external sensor of temperature will supply system given to air temperature in the street.
Room sensors of temperature promote comfortable temperature in certain rooms.
The sensor of leak of gas will give a signal on the panel and will report about leak by a shrill signal.
Fire-prevention sensors react to existence in air of a smoke or temperature increase over critical size.
The leakage sensor of water will block the valve cut in a water supply system.
Well, that’s all I wanted to say about this topic.
Thank you very much for you attention.
If you have any questions, please ask me.
