Smart technology – fi nding the right balance for energy effi ciency

S
mart technology extends from the private sphere to various branches of industry and global IoT-based networking platforms. With smart technology, data from
devices is collected, exchanged and bundled via intelligent networking, to provide technical and price advantages in any sector. Artifi cial intelligence (AI) is enabling an even greater level of automation, providing decisive advantages. In smart city setups, sustainability, safety and high quality of
life are key today. Modern technologies from the fi elds of energy, mobility, urban planning, administration and communication are networked to improve residents’ quality of life. From parking guidance systems in multi-storey car parks to energy supply, processes run more efficiently and sustainably. Modern, intelligent buildings usually use automated,
energy-efficient decentralised energy supply and can be precisely controlled in terms of energy consumption. Existing buildings can also be converted into smart buildings as part of modernisation and renovation projects. So-called heat maps are used wherever the density of a specifi c parameter needs to be measured – and measures need to be taken in real time wherever possible. GEYER products are used in a wide range of intelligent concepts for the demand-based control of heating, cooling, ventilation and lighting solutions. Low power consumption and low tolerances, coupled with
excellent performance in extreme weather and vibration conditions, make GEYER products the right choice for networking applications in smart cities.
Smart grids and smart metering Smart grids enable real-time monitoring and control of grid facilities. Intelligent devices monitor energy generation, transport, storage and distribution, as well as consumption. Data gathered from these devices is used to create a grid profi le and regulate the energy grid. We are increasingly seeing terms such as ‘Internet of Energy’, ‘Integration of Renewable Energies’, and ‘Grid to Vehicle Integration’, as they become important.

www.electronicsworld.co.uk Global climate targets and programmes for the transition
to renewable energies require smart grids in which electricity producers and consumers communicate digitally. This requires devices known as smart meters. A smart meter system typically consists of a digital
meter and a communications unit known as an SMGW (smart meter gateway). This gateway is connected via LAN or mobile communications, to transmit the measured electricity consumption to the relevant electricity network operators.
The same concept applies to any application that
requires energy consumption monitoring. Although the introduction of smart metering systems
began several years ago, it is expected to reach its peak in the coming years. Manufacturers of smart meter devices are currently focusing on a new generation of devices in new frequency ranges with a narrower channel spacing, the so-called SRD-860 frequency band (ZigBee, IEEE802.15.1, LPWlan, etc.). This is changing the technical requirements for quartz manufacturers and posing signifi cant challenges in terms of accuracy and stability.
Smart urban mobility Another area of application where energy efficiency and sustainability are important is intelligent mobility solutions, in which traffic volumes are continuously planned, monitored and thus managed, to prevent gridlocks, traffic densities and CO2
emissions. All future-orientated concepts will use smart devices and
controls in one or another, and the following are the areas they all have in common: • Automation. • Connectivity. • Energy efficiency. • Miniaturisation. • Sustainability. • Competitiveness.
