 Hot items displayed before entering the tunnel Infrared cameras and RFID chips at the tunnel entrance to prevent a truck with dangerous goods catches fire inside the tunnel, Siemens has developed a system consisting of a combined video and infrared camera to identify the critical parts of a truck is about to become overheated car before running into the tunnel. The camera detects if the vehicle is a truck and then compares the data stored on the allowable temperature of wheels, brakes and engine with the measured values. Is the temperature too high warns traffic management for the tunnel. To further identify the load a vehicle with it in the tunnel, the company has developed an RFID-based ID system, as information displays that will sit on the vehicle can be dirty and can not be read from the video images. RFID chip can be activated by the reader from 50 meters. The case of active RFID has therefore become power dependent. To save power circuit is activated by the reader. A special encryption chip that prevents the information can be fueled by unauthorized home. By knowing which cargo car with it can fire to insert the correct extinguishing a fire should occur in the tunnel? |
