Home users of smart systems ensure that they are extremely useful every day and are easy to use on their own, children and guests. Systems with radio communication should be installed e.B. during the renovation of the house.
Before the advent of smart home technology, each installation in the building performed only a specific task (e.B. a boiler heated the house and the hot water, an alarm and monitoring system guarded the safety of the residents and their property, etc.) and had its own automation system with separate controls and remote controls for operation.
The problem with different controls occurred when homeowners began to use more and more modern equipment and appliances such as ventilation and air conditioning, multiple lighting, multimedia, shutters and awnings, automatic irrigation. Engineers and electrical engineers then jointly developed intelligent technologies that combine various household appliances into one system and enable their uniform control. However, simpler management is only one of the many advantages of technological thinking for humans.
WHY IS IT WORTH HAVING A SMART HOME?
With this technology under your own roof, you can reduce the cost of using the building, increase the feeling of security and comfort, make the time at home more pleasant and if you invest in a flexible automation system, freely expand it and adapt it to the ever-changing requirements and ways of life. It is important that you do not have to be an electronics technician to be able to operate it.
savings. From an economic point of view, a properly configured intelligent system effectively reduces electricity and gas consumption. It has been calculated that in single-family homes, the savings of these energy sources are as high as 30%.
Smart Home hat viele VorteileThe intelligent system, in conjunction with motion detectors, can turn off the light every time it is detected that there is no one left in the room. Always after opening a window or patio door, turn off the mechanical ventilation and air conditioning. For sleeping, working and school or for a longer holiday – it lowers the temperature in the rooms and disconnects unnecessary devices from the grid. It also prevents water wastage, e.B. because the automatic irrigation system does not turn on when it has recently rained.
Safety and comfort. From a safety point of view, the most important advantage of “thinking” technology is its efficient operation, which results from the possibility of exchanging information between all coupled elements. If events occur inside or outside the building that are potentially dangerous for the occupants, he must react immediately by initiating alarm, security and deterrence measures. The convenience of operating the system lies in the remote execution of a series of control and management activities for the users.
HOW DOES A SMART HOME WORK?
The work of the system is controlled by a computer (extensive control) that collects and processes signals from various sensors in the house and garden. For signal transmission, electrical cables or radio waves are used. Sensors (movement, humidity, pressure, light intensity, floods, smoke, Chad, sleep gas, etc.) detect changes inside and out and transmit them to the central unit. There are also systems without a central unit, in which each of the elements decides which signals from the detectors are important to them.
FunktionsweiseAny change made in one subsystem must be immediately transferred to the others. All subsystems must take this into account and respond appropriately without delay. For example, after detecting traffic outside the building during the absence of residents, the system sends information to the building’s security office and to the owners, while at the same time carrying out a series of remedial actions on site – e.B. turning on the lighting in the house and garden, turning on an acoustic signal, lowering the outdoor blinds, blocking the door.
If the owners leave the window open on other occasions, the system also notifies them immediately, but above all changes the operation of heating and ventilation so that they do not incur unnecessary costs.
IS IT BETTER TO HAVE AN OPEN OR CLOSED SYSTEM?
High flexibility is one of the most important parameters when choosing a home automation system. The system can be reprogrammed several times and adapted to the current needs of the residents, extended and new devices and functions can be added in the future. However, extensibility depends on a good design and the type of intelligent technology used.
So-called closed systems offer products (technology, programs, devices, etc.) only from one manufacturer. When choosing such a system, investors can not resort to products of other companies. The opposite is true of the so-called open systems. Software, devices and hardware for them are manufactured by many programmers and many companies. One of the most popular open systems, suitable for single-family homes, is, for example, the KNX system, formerly known as EIB. All products used in this system are compatible, although they are manufactured by more than 100 companies.
Smart systems are not cheap, so it is better to pay attention in advance to the fact that they perfectly meet the individual requirements of each household and building in which they live. Before carrying out the project, it is worth learning about the capabilities of several open and closed systems.
A VERY EXTENSIVE PROJECT
The building to be erected can be equipped with an intelligent installation based on traditional cabling. In the existing one it is easier to install wireless radio systems. Although the latter are usually more expensive than conventional (cable) walls, forgings and repairs that are stressful for residents are avoided.
The laying of the cables, the placement of the sensors and all other necessary elements of the system (e.B. motors, actuators, controls, buttons) should be specified in detail by the project manager. It is best if it contains a series of execution projects for certain plants – electrics, alarms, multimedia and, of course, intelligent. Before starting the project realization, it is necessary to thoroughly analyze the needs and requirements of the residents.
FUNCTIONS OF THE SMART HOME AT A GLANCE
For the users of single-family homes, the function of intelligent automation is the remote control of heating and electrical installations. As a rule, this also includes equipment responsible for the safety of the house and its occupants, ventilation and air conditioning systems. Of course, the room for manoeuvre is even greater.
Heating, ventilation, air conditioning, ventilation
Temperature and humidity control in a smart building is based on temperature sensors in every room, an outdoor weather station, and humidity sensors. When users leave the house, the system lowers the temperature, closes the windows and controls ventilation and air conditioning more efficiently. After the return of household members (or before their return), the elements of the system begin to work in a different mode, quickly bringing the room to a comfortable temperature and humidity. In rarely used rooms and at night, a cost-effective operation can be programmed, while the holiday mode can also be programmed on the go.
In rooms, the lamps switch on or off remotely, shine brighter or dimmed via motion detectors (e.B. type PIR) and light intensity sensors. Outside (in the garden, on the terrace, at the entrance gate and at the gate) the control of the light points is regulated by twilight sensors. In many intelligent households, so-called lighting moods are configured from selected light points. They are used wherever it is worthwhile to create an individual atmosphere, e.B. in a representative hall, living room, dining room, kitchen, multimedia room.
So-called light paths are marked for effective access to the property, access to the garage and the house entrance or when the residents have to go to the toilet at night (in this case, dimmed light or a sensitive LED light is usually used). In addition, it is possible to simulate the presence in the building with the help of light, this function is directly connected to the safety function.
Alarm and monitoring
The intelligent system can be integrated into the alarm system or building monitoring. It is irreplaceable for protection against accidental events caused by fire, Chad, gas, etc. The safety of the occupants and the building can be ensured by numerous motion detectors, smoke, charge, gas (including sleep). The panic button near the owner’s bed triggers a series of events – it sends information to the security office, can trigger an acoustic signal or illuminate the building.
An interesting security measure is access control – residents use an individual card or key that is recognizable by the system in their home. A useful solution is a special button that, when leaving the house, can turn off all unnecessary electrical appliances during our absence (except, of course, refrigerator, boiler, etc.). With the push of a button, you can be 100% sure that the iron, oven, café and induction hotplate will no longer work.
Roller blinds, awnings, blinds, blinds
In summer, when the sun shines too strong, the remote control allows the relief of the ventilation or air conditioning by automatically lowering blinds, shutters or awnings over terraces and balconies. In winter, lowering the outdoor blinds additionally protects the interior from frost and supports the heating system.
A large number of users incorporate the so-called multi-room system, i.e. a multi-zone system and a home cinema system, into the intelligent system. By integrating the multi-room system with speakers and controllers installed in each room, they can use modern audio devices throughout the building. The sound “wanders” with them from room to room.
Automatic irrigation begins after the information via twilight sensors and soil moisture sensors has been sent to the controllers. A motion detector near the sprinkler system protects the garden user from unwanted wetting, while a rain sensor blocks the irrigation system in case of prolonged rain.
Filling of sewage and rainwater tanks
Septic tank level sensors, coupled with the intelligent home system, make it possible to avoid the flow of waste to the property. They inform the owners (e.B. by SMS) about the need to call the slurry truck. They are also perfect for rainwater storage.
