Monitoring and Control System for Highway Tunnel.pdf

1) System Structure

The system consists of lighting system, ventilation system, traffic guidance system, CCTV system, fire alarm system, fire control system, emergency phone system, and broadcasting system.

The system can also be divided into three parts: the field layer, communication layer and management control layer.

The field layer contains detection devices like fire alarm sensors, vehicle detectors, COVI, visibility instruments, wind velocity and direction instruments, etc, control devices like controllers in traffic area, lighting area and ventilation area etc.

The communication layer refers to the communication between controller, PLC and control center, realized by industrial Ethernet switches.

The control center contains a computer station, large screen monitor, sound and light alarm, etc.

2) Network Requirements

The industrial Ethernet switch of the optical fiber ring network must be fast-redundant, wide-temperature, good protection class and have strong EMC immunity to work in the harsh environment of tunnels.

3) Product Application

SICOM3000/SICOM3024/SICOM4000/KIEN6000 Industrial Ethernet switches are connected to optical fiber ring network to monitor the environmental factors of the tunnel.
