Carandini was responsible for lighting the L’Hospitalet de l’Infant railway station, which redraws the train line between Tarragona and Valencia and frees up the space occupied by the current tracks that cross the nucleus of many neighbourhoods and are on the sea front.
Lighting solution
The project had to meet the lighting levels for each of the zones: Platforms, shelters, car parks, roads and underpasses. Regulatory lumen levels were established, but uniformity should far exceed those requirements for the comfort of users of the areas.
The lighting solutions that Carandini used were V-MAX luminaires for outdoor roads and car parks, Junior on platforms, HFL on shelters, which always provide correct lighting levels, to ensure the safety of people passing through the station.
Planning lighting installations would not be a complete task today without a lighting management solution to match the best technologies available. For this reason, the implementation of a system of regulation of lighting was decided on that would increase the lighting levels of the platforms prior to the arrival of the trains.
In addition, for the entire installation; lighting control for each zone was required in order to adapt energy consumption to opening times, the presence of natural light, and passenger traffic. Finally, all of this would work automatically and be integrated within the overall control software for the facility, using SCADA of the installation, using SCADA technology.
System and architecture proposed
To achieve autonomous operation for the luminaires, it was decided to use the Carandini Controlux Engine system. This system allows a wide range of tailored solutions to be implemented and integrated into the most common communication protocols in the field of industrial automation and smart cities.
For communication with the luminaires, the use of the DALI control cable and protocol was proposed. As an intermittent, high volume infrastructure, communication with the luminaires could be guaranteed without exceeding the limitations of distances and devices within the communication protocol.
In order to regulate each group of luminaires differently, the arrangement of various control BUSES was defined. By using a protocol that allows the identified regulation of luminaires such as the DALI protocol, the number of control buses could be optimised by making 7 control groups with only 5 signal buses.
With the support of a team of specialist installers, the control buses were successfully introduced, with the implementation of the solution focussed on the validation of the software, specifically designed to meet the requirements of the project.
After the validation of the operation of all the luminaires and control devices, integration tests were carried out, which showed that all the variables were mapped correctly and the system reacted rapidly to the regulation instructions.
Results: Adaptation to the requirements in an integrated way
Carandini, with its portfolio of luminaires, was able to respond to the requirements of a project with high technical demands. In addition, with the Controlux Engine system it was possible to design a solution that met the full needs of each area of the facilities. This was possible thanks to the collaboration between the various companies involved in the project, the use of solutions with multiple modular functionalities, and standard industrial communication protocols. An open, flexible solution that allows automatic lighting control systems to be taken one step further, designed to interact with other devices. All of this leaves the door open for the design of facilities that meet current needs, but also those that have not yet been planned at the time of the facility design.
At Carandini, we are pleased to have helped to bring people closer, in addition to reducing the inconvenience and risk from trains passing at high speed through populated areas.
Junior – Platforms
Thanks to the versatility of fixings and optical distributions available to it, it shapes the light, taking it where it is required, thus creating comfortable environments in all kinds of urban spaces.
HFL – Shelters
The HFL series of luminaires with latest-generation LED technology provide quality lighting with excellent uniformity.
Controlux Engine
The system allows the implementation of a wide range of customised solutions and their integration into the most common communication protocols in the field of industrial automation and smart cities.
