Civil airport surface monitoring system

Abstract

The invention discloses a civil airport surface monitoring system. The system comprises a supervisory computer monitoring system and a ZigBee wireless network positioning system, wherein the supervisory computer monitoring system is positioned in an airport surface monitoring room; and the ZigBee wireless network positioning system is positioned in a parking apron range and consists of three kinds of network equipment, namely fixed reference node equipment, vehicle-mounted mobile positioning node equipment and a coordinator gateway. The system can immediately and accurately reflect the condition of a moving vehicle; and when the distance between the moving vehicle and an airplane reaches a preset value, an alarm can be sent to a driver so as to immediately prevent the accident of collision between the moving vehicle and the airplane. A visible and convenient vehicle information management platform is provided for airport station site management, and the on-site operation command management level of an airport and the operation safety and the operation efficiency of the airport are improved.

Description

【Technical field】 [0001] The invention relates to a civil aviation airport scene monitoring and management system, in particular to a civil aviation airport scene monitoring system capable of sending prompts to vehicles approaching or working near an aircraft to avoid collision accidents. 【Background technique】 [0002] When a vehicle hits an aircraft on the tarmac or taxiway, such accidents are mainly caused by the driver of the vehicle driving illegally (such as the vehicle not following the prescribed path, approaching the aircraft at an excessive speed), approaching the aircraft unconsciously, etc. In 2003, a passenger plane of an airline was crashed by a tractor at Ningbo Lishe Airport and scrapped; in 2005, three passenger planes were crashed by vehicles at Baiyun Airport, Xianyang International Airport, and Capital Airport respectively. In recent years, accidents and incidents in which aircraft are collided by vehicles on the tarmac continue to occur. [0003] Nowada...

Problems solved by technology

However, GPS has the following problems: (1) GPS positioning accuracy is generally 30-50 meters, which cannot meet the positioning accuracy requirements of airport vehicles; (2) The first capture time of GPS is too long, generally within 2 to 3 minutes; (3) Vehicles When entering the warehouse, passing through the underground passage, or being blocked by airport buildings or facilities, such as corridor bridges, the GPS system is not very reliable or even loses the target; (4) using GPS, only the mobile unit can obtain the positioning data. Transmission to the control center must be combined with other communication methods, which will increase equipment and operating expenses to a large extent; (5) The GPS system is easily blocked, because the location of the transmitting satellite is very high and far away, and the distance to the receiver The signal is very weak and therefore prone to interference
