Airport surface monitoring research of Civil Aviation University of China bears new fruit

Early in 2010, Personnel, Science and Education Department (PSED) of CAAC hosted a program appraising meeting undertaken by Aeronautical Automation College of Civil Aviation University of China (CAUC). This project dwells on the study of airport monitoring system, anti-collision and dispatching system based on the network of radio location. Sun Yigang, a professor of Aeronautical Automation College of CAUC, has been in charge of this project. The appraisal commission is composed of experts from Beijing University of Aeronautics and Astronautics, Beijing Institute of Technology, Tianjin University, Tianjin Polytechnic University, Tianjin Binhai International Airport, Capital Airport Construction Company, Beijing Bowei Airport Support Ltd. . All the experts attended the appraisal meeting. After appraisal, the commission believes the program employs advanced technology with a professional design, filling the blank of this technology in China. This technology reaches advanced level in the world. This program employs radio location system based on Zigbee wireless sensor networks. This technology, by means of collecting the information of the location of the moving vehicles on the apron through range positioning system: RSSI, can give an alarm to drivers in an effort to avoid the collision of vehicles and aircraft. What’s more, using RSSI can have a dynamic positioning precision of 1-3m with each positioning time less than 12 ms. In addition, the monitoring picture can provide coordinates and other detailed information of moving vehicles, accordingly, crews of the airports can effectively dispatch various vehicles based on the monitoring information. Further more, this system resistant to electric-magnetic interference can longtime work stably and reliably to its low power consumption. All in all, the fulfillment of this program lays a solid foundation for the follow-on applications of the airport surface monitoring system, anti-collision and dispatching system.
