In Dubna created the world's first single-wire transmission line, combined with high-speed data transmission. Intellectual development of the distribution network and the data transmission carries a small innovative company of the University "Dubna" — the company "Maison", a resident of a special economic zone "Dubna".
- The video surveillance system based on smart distribution network transmission and data in Dubna.
No wonder they say that everything is new — it is well forgotten old. At the beginning of XXI century, the University "Dubna" based on the technology of the inventor in the field of electrical and radio engineering, engineer and physicist Nikola Tesla, who in the XIX century, proposed a method of active power transfer using resonant properties of a single line made of a metallic conductor, the first in the world combined power transmission line and information. The line is based on a standard fiber optic cable laid between the pillars.
In Dubna are already two test landfill exploitation of intellectual distribution network transmission and data — on the university campus and on the embankment of the Volga in the street. Builders.
The system is based on a fiber optic cable with steel suspension cable, suspended on poles lighting campus. Consumers of electricity — lighting street lighting, video cameras, wireless access points, Wi-Fi, connected by optical fibers to their own servers, monitoring, billing, management and supply of power on the basis of digital substation forming the passage of the capacitive charge along the cable route. Modular converters needed to power devices designed for standard power supply, equipped with controllers control the parameters of the formation of stable resonant oscillations in the line. Free optical fiber cables are used to connect networks of various university buildings in a single data network, telephony, video surveillance systems, access control and management.
The second line of continuous Wi-Fi zone along the embankment of the Volga (the school number 9 to the pool "Archimedes") with a length of 1250 m was put into operation in the spring of this year (in test mode started to work in August 2012). This line extends a single information-educational environment of the city, created by the University "Dubna" in 2004.
It also implemented a system of single-wire transmission of electrical energy by supporting cables fiber optic cable connection. Wireless access points operating in the standard 82.11g, provided with food and transport data at high speed through a standard fiber optic cable. Antennas point of the line of lighting poles in the side of the Volga, which provides Wi-Fi coverage throughout the waterfront recreational areas. Internet access for students and teachers of the University "Dubna" is possible with the existing password, and anyone can register with the system by connecting to the site on-line (SSID wireless access systems «iNET»). In the area of Wi-Fi access is also possible to operate an IP-telephony University "Dubna".
The advantages of a single-wire transmission lines are clear: is the transmission of electrical energy over long distances without the use of transformer substations, the lack of a line of non-ferrous metals, reduced capital costs for construction of transmission lines by 40 percent, a significant reduction of losses in electricity transmission, reducing the number of accidents on the line associated with the weather events, the fundamental lack of short circuits in the wires, increasing electrical parameters during operation.
Intellectual development of the distribution network and the data transmission carries a small innovative company of the University "Dubna" Company "Maison", which is a resident of a special economic zone "Dubna".
