Either used in new or existing tunnels, the TLACS is adjustable and offers several levels of configuration. It will adapt to a wide variety of operator requirements. The extent of the system’s options is incomparable. In addition, the flexibility of its component package makes it very attractive to tunnel designers, constructors, and operators, thanks to the system’s modularity that can be adapted to any tunnel length and configuration. What’s more, the TLACS’ easy installation makes it particularly interesting when repairing or renovating a tunnel: it is possible to convert any standard lighting system into an intelligent system—using the tunnel’s existing cables.
All components were selected, set, and adjusted to accommodate most options. This intelligence can render significant savings in terms of energy and maintenance loads. The TLACS can use the electrical network as a communication channel to trigger a bidirectional dialog between the lamp and network controller. This NWC can also use a broadband network, such as an Ethernet or a wireless network, to communicate with the central tunnel management software (ITPMS). This gives operators the flexibility to control the system centrally through a simple and easy-to-use graphical interface. Its monitoring function constantly controls the operating status of all lamps and system components, keeping operators up-to-date on system performance.
The NWC, the main controller of the TLACS, is installed in the tunnel lighting cabinet and supports a wide range of standard communication protocols. It has 2 configurable serial interfaces (RS-232/RS-485) and an Ethernet 1, 0/100 Mbit/s interface (metallic) to integrate with any higher system, such as SCADA.
