SMART CITIES concept
Smart cities are developed urban areas designed with a perspective of creating high quality of life and sustainable economic development via advancement in several key sectors including technology, economy, environment, mobility, people, and government. The concept of smart cities is aimed to offer a set of infrastructure and new generation services to citizens and local authorities with the support of Information and Communication Technologies (ICT) and Internet of things (IoT) capabilities. It consists also of a secure fashion to manage a city's assets. These assets include local departments' information systems, schools, libraries, transportation systems, hospitals, power plants, water supply networks, waste management, law enforcement, and other community services. Another basic issue in this framework is to involve citizens in a live, user-friendly and bi-directional informational structure (citizens/local authorities) with mutual benefits.
In this framework, Hemus Technologies created a Smart City IoT & Cloud system utilizing mobile internet and location services of users/citizens. With this system the citizens and visitors of the city, by tapping their smartphone on one of the many Cloud on Tap Information Tags (COTICs) that are installed all over the city, will be able to receive information about the current environmental conditions, news and alerts directly from the Municipality’s office, some risk assessment based on their health conditions and the current environmental conditions in the area, and also information on a live map about nearby points of interest. This system consists of an administration platform hosted in a secure Cloud, the deployed COTIC tags in the form of adhesive stickers that are installed all over the city, and a front end which the citizens and visitors are able to access via the COTIC tags with tapping their smartphones on them.
A version of this Smart City IoT & Cloud system is already installed by Aratos Group in the City of Athens and in the City of Nafplio, in Greece. Similar versions are currently prepared for Bulgarian and other European cities that have shown interest in our solution.
SMART & SECURE ENERGY NETWORKS concept
Nowadays, energy networks are handled via a concept of a “smart electrical grid” which includes a variety of operational and energy measures including smart meters, smart appliances, renewable energy resources, and energy efficient resources. Electronic power conditioning and control of the production and distribution of electricity are important aspects of this smart grid.
Fundamentally, the smart grid is an energy generation, transmission and distribution network enhanced by digital control, monitoring and telecommunications capabilities. In addition to providing real-time, two-way flow of electrical power, it also enables automated, bidirectional flow of information. Consequently, all stakeholders in the electricity chain – from generation plant to commercial, industrial, and residential users – gain insight into both electricity flow and the infrastructure transporting it. To add intelligence to existing infrastructure, new digital equipment and devices are strategically deployed to complement existing equipment. This new layer of digital equipment connects all assets being in fact an example of the Internet of Things (IoT) in action.
Security is a major key: without it, the smart grid, like any data network, cannot function. Electricity grids are valuable and critical targets that need to be protected from cyber threats. As a large system of distributed and interconnected systems, the smart grid offers an exceptionally large attack surface. Any successful attack on a critical element can jeopardize grid security and cascade into a whole system blackout. End-to-end security is therefore one of the major starting conditions for an effective digital energy infrastructure. Each smart grid subsystem, its associated assets and the data derived from those assets require specific security functions and solutions. The solution to secure a substation is not the same as the solution to secure demand response or protect personal data or operational intelligence.
Cyber security technologies and best practices necessary to protect the smart grid include: anti-virus, firewalls, intrusion prevention systems, network security design, defense-in-depth and system hardening.
In this framework, Hemus Technologies created a Smart & Secure Energy Networks platform that is about a holistic binary energy networks management & protection platform catering both for their Physical and Cyber Security and Safety, offering a unique blend of critical data collection input services and their fusion at Aratos’ designed operator’s HQ to C4I2 standards.
The holistic platform targets the following sectors of energy networks divisions:
- Air: Electricity/Telecommunications Grid
- Ground: Oil, Gas Pipelines
- Underground: Oil/Gas/Water Pipelines, Electricity/Telecom. Grid, Fiber Optics
The holistic platform provides big data collection and intelligent management from the following levels:
- Space, offering unique Satellite Remote Sensing Technologies,
- Air, providing customized Remotely Piloted Aircraft Systems (RPAS),
- Ground, with integrated combination of innovative Sensing/Monitoring Solutions,
- Underground, based on innovative Fiber Optics Solutions,
- SCADA, Innovative Integration and Big Data fusion.
Customized versions of the Smart & Secure Energy Networks
platform are promoted via Aratos Group worldwide to governments and big energy companies.
