Tai Lam Tunnel

Application:

Tunnel environmental controls.

Scale:

More than 5,500 points spanning a 4.4-mile long tunnel.

Solutions:

UCOS monitors and controls tunnel ventilation, power management, lane control, lighting, closed-circuit TV, fire service, HVAC, plumbing and drainage, and high/low voltage power supplies.

Digital fiber optic repeaters help extend the communications range of the I/O over such a long distance. Dual Ethernet networks improve reliability.

CSI engineers also implemented a full manual control system that replaces all automatic control if the operators enter manual fallback mode, thus allowing operators to manually control selected devices inside the tunnel.

A mosaic mimic display in the control room provides a wall-size overview of tunnel ventilation and lighting, as well as high voltage and low voltage power usage.

Scope:

Project management, specification development, advanced application development, systems and equipment acquisition, system configuration and testing, instrument engineering, drawings and documentation, installation and commissioning, training, product and system support, field services.
