Atc Flight Conflict With The Low-altitude Warning System Design And Realization

On the one hand,air traffic control system,which can provide the controller with information about the height,position,heading and the like,is used by controller to keep a safe distance between the airplanes and the obstacles,so as to avoid conflict and,as well,make the automatic process of radar,flight plan and interactive operation come true. Although we have begun to develop the air traffic control system in China since 1970's,so many equipment from abroad are still used up till now.At the cost of high expenditure,it is of great necessity to have the equipment of air traffic control of our own. On the other hand,the status quo of air transportation keeps increasing,altogether with the quick pace of the economy's going up.The density of airplanes in the sky is increasing,meanwhile,the distance between them are much smaller.Therefore,it is pivotal to guarantee security of these airplanes. Aimed at the civil aviation airport,this warning system for air traffic control automation system includes amalgamation process of multi-radar data,warning process of flight conflict and low height,altogether with conflict display terminal.The theory and method about programming of all these units are told in detail in this article,and added to that is method of processing data with two networks and between two computers,master machine and slave one. The warning software system of flight conflict and low height has been installed and tested at Nanning,Lanzhou,Dalian and Wulumuqi airport effectively.
