Description

Command operation management system and method based on 1090ES link ADS-B technology

technical field

The invention relates to the technical field of air traffic services, in particular to a command and operation management system and method based on 1090ES link ADS-B technology.

Background technique

ADS-B is Automatic Dependent Surveillance-Broadcasting, which can automatically obtain information from relevant airborne equipment and broadcast information such as the position, altitude, speed and aircraft identification code of the aircraft to other aircraft and ground stations without manual operation or inquiry. It includes ADS-B OUT function and ADS-B IN function. ADS-B OUT is mainly used to realize effective ground-to-air surveillance of aircraft. ADS-BIN is an advanced application of ADS-B, which can enhance the crew's situational awareness of surrounding traffic. .

There are three data links available for ADS-B worldwide, namely 1090ES (1090 MHz Extended Text), UAT (Universal Access Transceiver), and VDL-4 (Mode 4 Very High Frequency Data Link). Civil Aviation of China clearly adopts the ADS-B technology of the 1090ES link, and requires all domestic transport aircraft to install the 1090 link ADS-B OUT airborne equipment mandatory. At the same time, the 1090ES link is also applied to ADS-B in the vast majority of countries and regions in the world. primary link.

With the rapid development of the civil aviation transportation industry, the air traffic is increasing rapidly. Higher requirements are put forward for airspace resource utilization, flight safety and operational efficiency. ADS-B is the future primary surveillance technology identified by ICAO ICAO. As an advanced application of ADS-B, ADS-B IN can significantly improve flight safety and improve airspace operation efficiency, and is a key technology to realize the modernization of air transportation system. The realization of ADS-B IN function requires that the aircraft must be equipped with airborne equipment with ADS-B IN function. Relying on the functions of the ADS-B IN airborne equipment, it enhances the crew's ability to perceive the surrounding traffic situation during the flight, and can achieve the optimal operation of each flight stage at various stages of flight operation, such as cruise, approach landing, taxiing, etc. Effect.

At present, in developed countries in Europe and America, the relatively mature exploration of ADS-B IN function in various stages of flight operations is CAVS (CDTI Assisted Visual Separation Approach) and ITP (Flight Level Change Procedure).

CAVS refers to the use of CDTI to assist the crew in obtaining and maintaining visual contact with the preceding aircraft or designated other aircraft during the approach phase. This application allows the pilot to use the information provided by the CDTI to maintain the own aircraft separation from the preceding aircraft in lieu of the EVA visual information when the EVA visual information is temporarily lost.

ITP means that on the premise that the information obtained by an aircraft equipped with suitable equipment meets the ITP start-up standard, the crew can perform climb or descent maneuvers to achieve the desired flight level and realize the change of the level. This application can make the aircraft more in the most At the same time, it can avoid high-density flight or the level with unstable airflow.

Among the existing patents, in the aspect of airborne equipment, the invention patent with the application number of 201810756542.X discloses a system and method for assisting visual separation with a cockpit traffic information display (CDTI) using a vertical position display. The provided system and method on a landscape display and using a vertical position display (VSD), presenting additional relevant visual approach information, such as the vertical distance between own aircraft and target aircraft, the rate of descent of own aircraft and target aircraft, and own aircraft based An alert is generated by comparing the determined distance to the selected other aircraft with the user-selected range distance. The invention patent with the application number of 201310123259.0 discloses an aircraft cockpit display system and method for presenting a trajectory program (ITP) for use. The invention provides a symbol system related to the execution process of the ITP displayed on the cockpit display , and proposed a method of implementing ITP by analyzing data to predict fuel consumption reduction.

In the above patents, the applications of CAVS and ITP are mainly concentrated on the airborne side. With the effect of the above patents, pilots can improve their perception of visual approach information and execute ITP procedures to improve fuel consumption. However, the improvement of flight safety and operational efficiency is a process of combining air and ground. The maintenance and orderly operation of aircraft during the flight phase are the result of effective communication and cooperation between pilots and ground controllers. In specific flight scenarios, if the achievements of the above patents are directly used, the applications of CAVS and ITP are mainly concentrated on the airborne side. The means of situational awareness of the ITP implementation process cannot provide effective ATS decisions.

In terms of ground command and surveillance system, the invention patent application number 201110322681.X discloses a regional airspace management and surveillance system based on TCAS system. The system responds to A/C or S mode installed in regional airspace through signal interrogation unit The aircraft of the aircraft can be inquired, and then the heading, airframe status, position and other information of the aircraft in the regional airspace can be obtained. At the same time, the system can be integrated into the airborne ADS-B network to obtain relevant status information of the aircraft in the form of receiving broadcasts. However, this system only provides basic information such as aircraft speed, position, flight number, etc., which cannot meet the information requirements of complex operations such as ITP and CAVS, and cannot realize the control-aided decision-making application of CAVS and ITP under the existing system or operating mode.

When the aircraft does not have ADS-B IN capability, the ground supervisor's instructions are used instead Crew CDTI information acquisition, direct command the crew to perform CAVS-like and ITP-like operations in the whole process of approach phase and altitude change; when the aircraft has ADS-B IN capability, ground controllers rely on this system to establish and communicate with pilots. Integrated situational awareness, assisting pilots to perform CAVS and ITP when necessary in accordance with the established CAVS and ITP operating procedures. Specifically, the present invention is based on the command and operation management system of 1090ES link ADS-B technology, and has the following functions:

Basic traffic surveillance and warning: Present the aircraft operating situation (position, speed, altitude, heading, etc.) in real time, and provide aircraft separation warning functions to assist ground supervisors in providing basic air traffic management services.

Correspondingly, based on the above embodiment, the command and operation management system based on the 1090ES link ADS-B technology of the present invention has the following technical advantages:

First, the system can provide ground supervisors with basic surveillance information, enabling them to grasp the flight situation of the aircraft in real time, and remind supervisors to pay attention to potentially conflicting aircraft through the aircraft separation warning function.

Whether the alarm conditions are met, and if so, output alarm information. In the approach warning process, the warning condition can be given based on the distance between the own aircraft and the designated other aircraft. At the same time, since the speed of the aircraft may change in real time, the pilot also has a reaction time when processing, so the warning condition is also It can be given based on the time, which includes the interval time between the local machine and the designated other machine and the reaction time of the person.
