Light signal systems

Control units | Switch cards | Software tools for light signal systems

Whether ready-to-use control units of the deTRA series, individually combinable components or an individually configured system - dresden elektronik provides you with the lighting signal solution which is optimally tailored to your needs. The control unit series deTRA already covers a wide range of applications. Simple nodes such as pedestrian crossings or complex nodes can be realized as stationary or mobile system and in centralized or decentralized design, depending on your requirements.

We accompany you from the first project draft to the commissioning of the traffic junction solution. With our many years of experience, we make sure that you receive an LSA solution which is optimally tailored to your needs.

Selection and adaptation of core control

  • Selection of the necessary control components
  • Determine the necessary functional additional modules
  • Adaptation of assemblies to operating conditions (cabinet installation as swivel frame or on mounting plate)

Combination with different switch cards

  • Selection of the desired structure in centralized or decentralized structure
  • If necessary, simulation of the necessary cable lengths depending on the illuminant and determination of the necessary cable cross sections
  • Selection of the circuit board depending on the desired illuminant

User-friendly software tools

With the easy to use software tools from dresden elektronik complex traffic projects can be realized fast and efficiently. From the creation of the traffic data over the test of the logic up to the supply of the system you receive a comprehensive software package.

  • deTRAver: Creation of the supply data
  • deTRAsim: Simulation of supply data and online visualization on site

Supply tool deTRAver

With deTRAver you can create the supply data for each individual node. You can supply up to 3 sub-nodes with up to 64 signal groups and 128 signal heads in up to 32 programs. A large number of overviews support you during parameterization. Individual solutions can be implemented using an integrated logic module.

By selecting the menu items in the tree structure, a clear, intuitive user interface is created. Each menu item is assigned a window for defining the corresponding parameters. The created parameter set can be saved and reloaded by the simulation tool deTRAsim.

The download of the supply and VS-PLUS or LISA+ data to the control unit and the upload of the error and event memories is done either via a serial interface or via Ethernet.

Simulation tool deTRAsim

The graphic simulation program deTRAsim supports you in testing and commissioning the plant. The developed logic is checked by test scenarios with detector simulation.

Various views (signal generators, signal groups, traffic flows, detectors, etc.) can be selected and evaluated. A direct connection to the control unit with online visualization is possible from deTRAsim.

Thanks to the different views and test scenarios, system parameterization can be perfectly coordinated. For an all-encompassing overview, you can import an intersection plan as background image. Signal transmitter symbols, detectors, etc. are then assigned to this plan accordingly.

LISA+ direct supply

If the supply data was created in the LISA+ workstation, it can be used directly and loaded using the LISA+ direct supply module. Only the manufacturer data has to be adapted in the supply tool deTRAver. This eliminates the error-prone and inefficient "writing off" of the VTU and, above all, the VA logic.

VS-Plus

VA logic created using VS-Plus can also be loaded in the deTRAver supply tool. In addition to the manufacturer data, the VS-Plus IDs must be entered to complete the complete VA logic.
