General description
- complex technological equipment for tunnels
- used for traffic safety and passengers in during standard or emergency situations in the tunnels
- the complex solution contains a control and information system, a camera system, a set of systems for measuring physical values, a system for measuring traffic data, a radio network in the tunnel, backup power supply systems, SOS securing, equipment of before-portal segments and other devices according to the specific project
- suitable for smaller constructions with a shorter tube, but also for long highway tunnels of several km length
- high level of security
- all system are designed and supplied in accordance to valid standards and technical conditions of Ředitelství silnic a dálnic ČR
Basic technical description
- the control system ensures complete control above all systems
- a part of the system is a well-arranged diagnostic system and a archivation system of measured data
- IT systems control the changing traffic signs, vehicle signal devices and illuminated traffic signs
- a MUR-05 stationary camera system is used to measure section speeds
- a video detection system is used for recognizing orange boards on vehicles transporting dangerous loads according to the ADR agreement and also for identifying the level of danger in case of an accident
- together with weight sensors and induction loops, the camera system enable the measuring of vehicle weight
- for securing safety key physical values are continuously measured – carbon monoxide, speed and direction of air flow (opacity), air temperature and many more
- the power supply of technological devices is supplied from the mains during standard operations; during this time an alternative power supply connection and an independent backup power supply are always ready to be used
- a part of the realization is the equipping of the before-portal section with changing traffic signs, information boards and a dynamic system of measuring vehicle height
