The seminar-presentation of the results of the selected projects for AO "Russian Railways" took place on November 22, 2018 at the center for innovative development of Russian Railways, Moscow.
A.V. Dvorkovich, doctor of technical sciences, member-correspondent of RAS, Director of Phystech School of Radio Engineering and Computer Technology of MIPT, presented the RAVIS project: "RAVIS 2.0 – Technology of digital terrestrial multimedia broadcasting and communication of VHF range and the possibility of its use for the needs of Russian Railways on the basis of the results of a comprehensive project: "Development of software and hardware for terrestrial video broadcasting systems and communication of mass and special applications using a limited frequency resource" (2015-2017).
Possibilities of applying the results of a complex project for Russian Railways
Possibilities of applying the results of a complex project for Russian Railways: “SMART RAILWAY STATION BUILDING and SMART STATIONS”
Possibilities of applying the results of a complex project for the Russian Railways: the transfer of images and videos
Info transfer to the driver's cab from the next crossing (in case of interference – the vehicle goes to the crossing and gets stuck in front of the approaching train). It is possible to transfer video or images from the crossing in an allocated frequency band 160 MHz for a particular train driver, and not to everyone in range.
Image/video transmission is performed on a narrowband channel from 10 kHz (slide show) to 250 kHz (full-length video).
RAVIS allows to urgently transfer video/images from the place of the train derailing through the air to the RAVIS receiver and then to the nearest Transtelecom or another operator node, and from there via optic fiber to the Situation center.
Possibilities of application of the results of a complex project for Russian Railways: single-frequency network along railways
The construction of single-frequency broadcasting networks for mobile reception along railway lines opens up unlimited possibilities of broadcasting for continuous mobile reception of various audio and video programs (for children and adults, road information, etc.). Passengers will be able to watch TV programs on the screens installed inside or listen to radio programs throughout the trip.
