📋 Tender Overview
The exercise of the Fire and Rescue Service of the Railway Administration today tested the operation of the new security system of the Brezensky tunnel including the unique Accur8vison system based on accurate laser detection. The second longest railway tunnel in our territory is located on the line from Chomutov to Zatec. The installation of equipment on the tunnel portals will help to eliminate the unauthorized entry of persons into its tube and thus increase the safety of railway traffic.The state-of-the-art technology of the Accur8vison system uses a combination of LiDAR technology known for example from autonomous vehicles and camera surveillance to detect motion. LiDAR technology works on a similar principle as radar but instead of radio waves it uses a light beam emitted by a laser diode and is characterized by a very high detection accuracy in the range of 2 to 3 cm. The system also incorporates elements of virtual reality simulating the real world with the help of 3D maps created in the Unity system which is also used for the creation of computer games or film production.The new security system is unique and accurate location of all moving objects in the guarded zone and thanks to its unique technology can direct rotating cameras directly to the place of alarm and completely autonomously monitor the intruder and the direction of its movement. He can automatically prompt the intruder to leave the guarded area in four language versions and if he does not obey he will warn the narrator of the danger. The whole process of supervision and response to the situation is thus significantly accelerated.In the event that the dispatcher evaluates the alarm message as a serious breach of safety stops traffic on the track and takes over the supervision of the entire guarding system ie control of rotating cameras and radio. . For increasingly busy conventional lines and the future operation of high-speed lines VRT this is an essential element of the whole jigsaw puzzle of safe railway traffic.The system always works with three laser sensors on each portal used to evaluate objects and a camera system. It thus provides spatial detection which also includes the area above the portals. CCTV technology works independently the recording from the cameras on the portals is stored for 168 hours in accordance with the provisions of the GDPR.The presentation of the new security of the Bezensk tunnel took place at the Droukovice railway station. It was followed by a tactical exercise of the components of the Integrated Rescue System. He was proclaimed II. degree of fire alarm it was attended by 10 units. The exercise was focused on a simulated fire of a GW Train train set. As a result of a technical defect a fire occurred on it approximately 900 m from the Droukovice entrance portal. Upon arrival at the scene the rescue and evacuation of passengers and the liquidation of the fire were carried out. At the same time all elements of the tunnels safety equipment were inspected.The aim of the exercise was to verify not only the technical capabilities of all rescue services but mainly to check the ability of IRS units according to the alarm plan of the tunnel which is with a length of 1758 m the longest single-track in the Czech Republic.
