Smart home of the future for a comfortable and healthy living and working environment
The integrated electrical protection and control equipment from Eti, d.o.o. and Robotina, d.o.o., which have joined forces in this project, also contribute to the concept of a net-zero energy building.
Dom 24 h provides a complete electrical, thermal and information supply for living and working spaces. It contributes to the concept of a net zero energy building by being largely energy self-sufficient, thanks to its solar power plant and electric batteries, where surplus electricity is stored, with the use of super-insulating materials, a highly efficient ventilation and heat recovery system, the use of phase-change materials, high-quality paints and moisture-control coatings and a net zero energy building concept.
On higher power consumers, current transformers with the possibility of analysing various parameters (mains voltage, currents, frequency, operating and reactive power) and AC protection switches with arc detection are installed, which, by analysing the voltage and current signal, detect the form of the signal indicating the presence of an arc in the installation and thus switch it off. In this way, they help to prevent the occurrence of a fire at the installation.
Scheme of the distribution board:
The control part is used to control the heating (a two-way heat sub-station is installed to return heat to the district heating system), the blinds, the underfloor heating valves, the ceiling cooling valves, the heating water supply to the storage tank, the drinking water valves and the rainwater valves, openers, room thermostat, scene controller, LED strip brightness adjustment, door limit switches, occupancy sensors, outdoor light sensor, water spill detectors, heat pump, solar power, battery system and touch screens for operation.
Finished distribution board:
Communication between the devices is done using different protocols over LAN and WAN (modbus TCP/IP, restAPI, MQTT, socket sending), serial connection (RS-232 and RS-485 or modbus RTU), Canbus and wireless Z-wave connection. From the various devices communicating with each other using one of the above protocols, information flows through the concentrators to the gateway to the IP network. Through the IP gateway, it goes to one or more distributed servers for the provision of cloud services.
The lighting is controlled by a DALI digital addressable lighting interface. The DALI protocol allows individual or group control of luminaires and reliable communication via bus line.
Dom 24 h is a demonstration of a residential and work facility with state-of-the-art materials and state-of-the-art technology that increases individual comfort through simple operation, facilitates various tasks, saves time and costs and increases the safety of people and their property.
