“Smart house” has been on everyone’s ears for a long time, but it is often perceived in a narrow sense – as a system for controlling audio and video equipment. Meanwhile, its meaning is much wider, and the benefits for the owners of a country house are invaluable.
Under sensitive guidance
Therefore, a “smart home” is a complex of technical and software tools, the main task of which is to simplify and improve the quality of management of the building’s engineering systems. In modern country houses, it controls lighting, heating, air conditioning, security and fire alarms, as well as electrical networks, emergency equipment, home theater and multi-room systems. Engineering equipment connected to the “smart home” system works as harmoniously and efficiently as possible (for example, the air conditioning system will never work “against” heating), which allows you to significantly save on the operation of suburban real estate, and makes living in the background of nature truly comfortable.
It is characteristic that with the help of a “smart house” it is possible to control not only individual engineering systems, but also their groups by simply pressing a key of one of the scenario switches or a button on a wall-mounted or portable touch control panel. At the same time, in automatic or semi-automatic mode, the scenario specified by the user when configuring the equipment begins to be implemented.
Simple scenarios include, for example, controlling the operation of several lamps. So, after returning home from work, you can turn on the lights in all rooms at once with the help of one button. However, the “smart home” easily performs more complex tasks. For example, the “Evening” scenario will allow you to set the overhead lights to 10% of the maximum power, and the group of floor lamps to 50%, close the blinds, turn on the broadcast of your favorite TV channel or radio station. After touching the “Sleep” button, the light in the bedrooms will be gradually extinguished, but the next lighting in the hallway or corridor will be activated, the temperature in the bedrooms will be reduced by 1-2 ° C, and by the time of rising (after 6-8 hours) it will return to comfortable values . The “I’m leaving” scenario will ensure automatic turning off of the lights in the entire house, switching the climate system to economic mode,
The mouse will not jump
An extremely useful function of the “advanced” modifications of the “smart house” is the remote monitoring of the property. With the help of video cameras, you can watch what is happening in the cottage from anywhere in the world at any time of the day or night. All that will be required for this is access to the Internet and knowledge of the secret password, which is indispensable for entering the virtual system of managing your home. By the way, with its help, it will be possible not only to observe what is happening, but also to perform a variety of control actions in real time – activate and deactivate the irrigation system, to create the appearance of the presence of people in the house, turn on music or TV, lighting equipment , control the heating and air conditioning system. You can even remotely open gates and front doors to welcome guests,
The “smart house” also copes very well with the functions of a watchman of a country villa. The eyes and ears of the system are a wide variety of gauges and sensors installed in certain responsible places. For example, leak sensors can be installed during kitchen remodeling and bathrooms flush with the floor surface, which signal an emergency in the water supply system, and gas and CO leak sensors can be installed on the walls in the kitchen and in the boiler room. All premises, without exception, are equipped with fire detectors (react to smoke or flames) and motion sensors. If one of the sensors is triggered, the system will perform the necessary actions to localize the accident. So, in case of water leakage or methane leakage, the access of water or gas will be immediately blocked with the help of electromagnetic valves, the house will be transferred to emergency power supply.
The owner will be immediately informed about all significant events taking place in the house using the SMS notification system or e-mail, and about a fire or the fact that burglars broke into the house – security services.
In pursuit of perfection
Currently, there are different approaches to creating a “smart home” system. Installation architecture can be very complex. But to a first approximation, all “smart home” systems used in country cottages can be divided into centralized and decentralized.
Centralized systems are perfectly integrated into modern luxury cottages. They begin to be installed before the finishing work begins, and the work is often completed after the residents move into the cottage. The heart of the installations is the central controller, in fact, it is the brain of the system, from which signals are sent through various communication channels (most often via “twisted pair” type cables) to the executive and command units, which control the work of engineering systems. Executive command units have built-in microcontrollers, but the program that ensures the coordinated interaction of all components of the “smart house” is only in the centralized controller. The user can control all the engineering equipment with the help of very convenient and stylish touch panels.
By choosing a centralized system, the developer gets the most high-tech solution that ensures first-class operation of audio and video equipment. But in the event of a failure of the central controller, the system can only work in manual mode, which temporarily reduces the comfort of living.
A spacious niche or even a small room may be required to accommodate the central controller and auxiliary equipment. Of course, the price of such a solution may seem excessively high to many.
In decentralized “smart house” systems, there is no central controller. The system consists of sensors (motion, button press, humidity, temperature, etc.) and executive devices (or activators). The intelligence of the system is distributed among its components – each of them has its own microcontroller and control program.
Information exchange between components is carried out according to special rules (data exchange protocols are used for this purpose, of which there are currently a large number) using one or another information channel. The bowls all use a “twisted pair” type cable (its laying is carried out before the start of finishing), which ensures the transmission of information, as well as the power supply of the controllers. However, a radio channel or the existing power wiring of a country house is also suitable for broadcasting signals.
Systems operating on a radio channel and power wiring are easily installed in cottages where the final decoration has already been completed, since the laying of additional control communications is not required. The user interacts with the decentralized system using scenario switches, keypads installed in one or another room, the equipment can be reconfigured using a PC.
At a high quality level, decentralized “smart home” systems allow you to implement simple lighting and security scenarios, they are suitable for reliable control of mechanism drives (for example, roller shutters), some climate control operations, etc.
Decentralized systems allow you to manage a large number of components, are easily expanded and configured. They are reliable, the failure of any of their components does not affect the performance of the system as a whole. As necessary, the system can be supplemented with new elements, step by step increasing the comfort of equipment management.
The new security system from Siemens combines all monitoring systems, from motion sensors to gas leak alarms, into one device that can be controlled remotely. The emergency button allows users to directly contact the police and other emergency services.
