OPTIMUS® Roadside Outstation

The challenge

Since 1998, Green Way Systems GmbH, with its headquarters in Frankfurt/Oder and subsidiaries in Baden-Baden, Amt Wachsenburg near Erfurt and Erkner near Berlin, has developed innovative products and systems for road traffic technology. This includes the planning and realization of demand-oriented system solutions including project management and systems service - specifically  the collection of traffic data in temporary traffic situations and the control of mobile traffic systems. About six years ago, Green Way Systems was looking for a partner that would be able to supply a small, lightweight yet robust control cabinet - effectively the heart of any mobile traffic control system. The requirements for the development of the housing were demanding. The outstation needed to be designed for rental equipment. For this, the highest requirements for regular assembly, transport and disassembly as well as for storage and retrieval had to be realized. At the same time, the devices have to perform their service in the truest sense of the word 'in wind and weather'  - just as reliably  in blazing sunshine and great heat as in rain or snowfall.

Key features

• Designed for use in temporary traffic technology
• Developed for mains-independent operation
• Energy-saving due to solar-optimised components
• Wireless monitoring and control of the system using the latest mobile radio technology
• Operational range from minus 20 to plus 60 degrees Celsius
• Low total weight due to the use of aluminum
• UV-resistant pressure equalisation plugs serve for cross ventilation

The häwa solution

Together with Green Way Systems, the experts at häwa GmbH set about developing a specific solution. The result: The OPTIMUS^® outstation has been designed for temporary traffic technology applications. For this, the OPTIMUS^® was designed as a pole cabinet and developed for mains-independent operation. The components used are solar-optimized and conserve energy resources. The communication for the monitoring and control of the system is wireless and based on the latest mobile radio technology. OPTIMUS^® has been designed so that a large number of different actuators and sensors can be connected quickly, easily and without errors by means of a plug system. The conventional cabling and insertion of the cables through cable glands are, therefore, completely eliminated. Thus, OPTIMUS^® is a compact "all-in-one device" and ideally suited for the operating and installation conditions of temporary traffic technology.

häwa guarantees an operational range from minus 20 to plus 60 degrees Celsius for OPTIMUS^®. By using aluminum for the mounting plate with a size of 450 X 590 millimetres, a total weight of only 21 kilograms has been achieved and the housing tray is completely welded. Aluminum is not only lighter than sheet steel or stainless steel but is also more robust than other materials when used outdoors. Thanks to IP55 protection, the housing is protected against dust and water and has full contact protection. The seal is foamed all around. UV-resistant pressure equalisation plugs attached to the bottom left and top right of the enclosure serve for cross ventilation. OPTIMUS^® is supplied ready to use in light grey (RAL 7035). The housing is powder-coated and withstands environmental influences thanks to polyester quality. A special highlight is the mains-independent operation thanks to solar optimisation. Once again, with this cooperation häwa has shown how an individual customer solution can be realised thanks to decades of experience. Around 1,000 original OPTIMUS^® outstations from Green Way Systems, which are in use nationwide, have a housing from Wain as their 'heart' - a remarkable success story that has been making Germany's roads safer for many years now.
