Air traffic control automatic system secondary surveillance radar code directional allocation method

Abstract

The invention provides an air traffic control automatic system secondary surveillance radar code directional allocation method and belongs to the automation technical field. The method comprises the following steps: an ATC (air traffic control) system establishes an SSR resource allocation table of users in a parameter management module in the ATC system according to attributes of each SSR code segment of an SSR resource set by the users; the attributes of all SSR code segments are configured in the resource allocation table; and the ATC system allocates SSR codes meeting the attributes of the SSR code segments for flight. The method allows the ATC system to be able to support the users to customize the allocation direction of the SSR codes very flexibly, so that the users can control the allocation direction of each SSR code according to actual demands, and control the assignable SSR codes of each flight plan.

Description

technical field [0001] The invention belongs to the technical field of automation, and relates to an air traffic control automation system, in particular to a method for allocating codes and directions to secondary radar transponders by the air traffic control automation system. Background technique [0002] Air Traffic Control Automation System (Air Traffic Control System, hereinafter referred to as ATC system) is the most important technical tool for air traffic controllers to grasp the air traffic situation and manage air traffic in real time. [0003] At present, air traffic radar control is implemented in most of China's airspace, and radar identification is the premise of radar control. The airborne secondary radar transponder is a kind of equipment for the aircraft to automatically respond to the ground secondary radar interrogation signal. The secondary transponder is the most important and commonly used method for identifying aircraft in radar control. Therefore, b...

Problems solved by technology

[0007] The above-mentioned traditional technologies can only realize the cyclic allocation of SSR resources, but cannot control the specific allocation direction of each SSR. For example, the SSR code A1111 can only be allocated to flights bound for Beijing, or the SSR code A2222 is not allowed to be allocated to flights bound for Beijing. Shanghai flight

[0008] In this case, the borrowed SSR resources cannot be well utilized, resulting in the actual allocation of SSR resources at each airport is quite limited. When there are a large number of outbound flights, the SSR will not be enough. Or the SSR allocation is repeated, which directly affects the correct identification of air targets by the ATC system, and thus poses a potential threat to air traffic safety

[0009] 2. The causes of the shortcomings of the above-mentioned traditional technologies

[0010] According to research, most of the air traffic control automation systems across the country do not have the directional allocation function of SSR. Most of the SSR resources borrowed from other air traffic control centers adopt the same automatic allocation rules as ordinary SSR resources, or they are carried out by manual operation. The distribution and manual operation mode can meet the temporary needs, but the energy of the control personnel is limited, and it is inevitable that there will be work mistakes, and this manual operation mode is not a long-term solution
