BackgroundDue to the narrow space, low visibility, complex environment in the tunnel, the security management is difficult. For security, to improve traffic efficiency of tunnel, installed a set of intelligent monitoring system, including fire detector, jet fan, intelligent lightning, signal control, variable information board. When breaking of fire or traffic accident, monitoring system can be used to linkage management center, to evacuate people, upload real situation in the tunnel to help emergency rescue. In addition, set up a control center near to tunnel, for daily management.RequirementsFull GE fiber ports, meet with video, broadcast, alarm, information and data transmissionAutomatic redundant network connection, ensuring data transmission steadyDifferent traffic with autonomous cha...
