The solution was developed by a company in Austria called Polyfilld. The company was built in 2012 to provide RFID tags for non-woven synthetic materials installed between roadbed and asphalt. The RFID tag is carried out by a test vehicle equipped with an RFID reader, which can travel at speeds of up to 40 kilometers per hour.
Polyfilld is testing UHF tags and readers designed specifically for this solution by Schreiner LogiData. The first version of the RFID solution already installed and used in the United States uses a high frequency 13.56 MHz passive RFID tag that complies with the ISO 15693 standard. Since the reading range of the high frequency technology is limited, the reading rate of the application during the reading process of the vehicle is not high. The newly developed second edition solution uses UHF technology and is tested in North Austria.
Through this solution, road maintenance and inspection personnel can achieve "good communication" with the road, and can quickly find out the detailed information of road maintenance, such as the time of recent maintenance, the materials used, and the person in charge.
Polyfilld has been supplying high-frequency RFID solutions to London's transportation management since 2007, with a label installed approximately every 200 meters. Each tag has a unique code that is associated with road repair information in the backend database. The installation of the tag can be performed by the customer himself, and the tag information is initialized by the handheld reader and the related data is stored in the user back-end database. Polyfilld not only provides labels, readers, but also special middleware for compatible label reading systems and existing road maintenance systems.
The Schreiner LogiData RFID reader is installed on the road inspection vehicle. The reader reads the unique code of the tag and sends the code to the on-board computer via a wired network or Bluetooth.
The second version of the solution uses a solution based on ultra high frequency (UHF) technology, in which the tags and readers are supplied by Schreiner LogiData. The UHF reader includes a set of read/write antennas that increase the tag reading rate as the vehicle passes at high speed.
Since the summer of last year, the UHF system has been tested. So far, the system has performed well and the results have been satisfactory. Polyfilld has applied for patents in Europe and will soon be launched in the United States, South Africa and other places.
