KBS / MAV system to ensure of higher transportation safety of passengers in metro. It consists of several technological blocks which form, via their interconnection, for its users, a powerful tool for video monitoring (CCTV), audio services (Audio) and general data communication in wireless transmission environment between stationary part and train-sets.
KBS / MAV-TRLAN local network to ensure interconnection of all
KBS / MAV-DATA + KBS / MAV-INT interface for interconnection of other technological blocks
KBS / MAV-CBTC data transmission from automatic train control system (ATC) in relation to CBTC functionality
Description KBS / MAV
KBS / MAV system uses standard Ethernet environment for communication between several technological blocks of KBS / MAV system in relation to integration to dispatcher centre and servicing centre of customer. KBS / MAV system consist from several technological blocks:
KBS / MAV-WAL
wireless communication system to ensure wireless interconnection and control of communication between stationary and mobile part
KBS / MAV-CCTV
video monitoring system
KBS / MAV-IPPHO
audio communication system based on IP technology (passenger emergency communication system and communication system for train drivers)
KBS / MAV-TRLAN
local network to ensure interconnection of all KBS / MAV system components in the train-set
KBS / MAV-DATA + KBS / MAV-INT
interface for interconnection of other technological blocks (outside KBS / MAV system) in stationary and mobile part (train-set); data transmission from security systems, firealarm systems, system of uniform time and the others
KBS / MAV-CBTC
data transmission from automatic train control system (ATC) in relation to CBTC functionality
