With the rapid development of China's civil aviation industry, China's domestic flight traffic has maintained rapid growth in the past two decades. Although the sky is big, there are many aircraft. In addition to civilian aircraft, there are also military, general aviation and other types of aircraft flying in the sky. In order to ensure safety, a certain safe distance must be maintained between aircraft, which requires the air traffic control department to predict flight flow in advance. If the flight flow in a certain airport or a certain airspace is saturated or tends to be saturated, aircraft already flying in the air cannot wait still and can only handle it accordingly by implementing flight flow control. In the civil air traffic control system, it is the civil air traffic management system department that specifically implements the above-mentioned flight flow prediction and flight flow control work.

Civil aviation air surveillance equipment mainly includes primary/secondary radar, ADSB broadcast automatic related surveillance equipment and other equipment (hereinafter referred to as surveillance equipment). The surveillance equipment can accurately obtain the real-time position, altitude, and speed of the aircraft in real time. , heading, climb/descent rate and other raw surveillance data.

The Air Traffic Control Automation System (ATC) is the most important technical tool for air traffic controllers to grasp the flight situation in real time and implement air traffic control. In order to maintain continuous and precise monitoring of targets, the ATC system needs to receive, analyze and process the original monitoring data generated by each monitoring device.

Detailed ways

The embodiments of the technical solution of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only used to illustrate the technical solutions of the present invention more clearly, and are therefore only examples and cannot be used to limit the scope of the present invention.

It should be noted that, unless otherwise stated, the technical terms or scientific terms used in this application should have the usual meanings understood by those skilled in the art to which this invention belongs.

As shown in FIG1 , an embodiment of the present invention provides a method for monitoring the flow control situation of civil aviation flights, including the following steps:

S1, set flight flow control rules, manage and edit the flow control rules according to the flight direction, such as Kunming, Xi'an, Lhasa, Nanning, Guangzhou, etc. Multiple flow control rules can be set under each flight direction;

S2, set the display characteristics corresponding to each flow control rule; for flights that comply with a certain flow control rule, automatically display the signage of the flight according to the display characteristics corresponding to the flow control rule;

S3: For multiple flights that comply with the same flow control rule, calculate the time difference and distance between two flights in the multiple flights, and determine whether the time difference and distance meet the interval required by the flow control rule. If not, issue an alarm prompt.

In the embodiment of the present invention, flight flow control rules can be set, and the flow room controller can manage according to the flight direction, which is simple and convenient to operate; display features corresponding to the flow control rules are also set, and the flow room controller can filter the corresponding flights as needed. , improves work efficiency and reduces the probability of errors; it can also determine whether the intervals between multiple flights that comply with the same traffic control rule meet the requirements of the traffic control rule, and issue an alarm prompt if they do not meet the requirements. The flow room controller takes appropriate measures as early as possible.

In the embodiment of the present invention, setting flight flow control rules includes importing flow control rules published by other systems and/or creating and editing flow control rules.

Specific data items of flow control rules include but are not limited to flow control name, start time, end time, controlled waypoint, controlled departure airport, exempted departure airport, controlled landing airport, exempted landing airport, flow control reason, Limit type and limit time. In other invention embodiments, other specific data items can also be set according to actual needs.

In this embodiment of the present invention, the display characteristics include color and/or specific characters. When the display feature is color, each traffic control rule has its own corresponding color. For flow control rules belonging to the same flight direction, try to set a different color for each flow control rule in this direction to make it easy to distinguish. In the embodiment of the present invention, screening calculations can also be performed on all aircraft in the air based on the published and effective flow control rules.

For flights that meet certain flow control rules, the flight sign will be automatically displayed in the color corresponding to the flow control rule, or the specific characters corresponding to the flow control rule will be displayed on the flight sign. If a flight meets multiple flow control rules at the same time, a special character prompt will be given on its sign (such as arranging small squares of the colors corresponding to multiple flow control rules). Flights that do not meet any flow control rules, that is, uncontrolled flights, will be displayed with track symbols (such as a small airplane icon) by default.

The design goal of the existing ATC system is to be used by air traffic controllers. In their daily work, air traffic controllers screen and display aircraft targets mainly based on altitude, secondary radar transponder code segment, and whether the flight is related to the aircraft target. This seat is related to these three aspects. These three types of flight filtering and display functions are most commonly used by air traffic controllers, but they are of little use to traffic room controllers. The flow room controller's concerns are completely different from those of the air traffic controller. The flight filtering and display functions required are mainly the following two:

1) Only display the placard information of aircraft landing at a certain airport, or aircraft landing at certain airports. For example, only the placards of aircraft landing at Chengdu Shuangliu and Chengdu Tianfu airports will be displayed. The other aircraft will only use a specific placard. Small icons (such as small airplane icons) are displayed.

2) Only display aircraft signs that are restricted by one or several flow control rules. For example, only display all aircraft whose destination airport is Chongqing that meet the flow control rule <2 flights landing at Chongqing Airport within 30 minutes, minimum interval of 10 minutes>. The remaining aircraft are only displayed with a specific small icon (such as a small airplane icon).

The traditional ATC system does not have a filtering function. Traffic room controllers use the traditional ATC system. In order to achieve flow prediction and control, they can only manually control all flights one by one based on the flight's destination or the current flow control rules. Filter display. During the daily peak hours of flights, such an operation is extremely inconvenient and brings huge additional work expenses. It greatly reduces the work efficiency of the flow room controller and easily leads to errors in the work.

In the embodiment of the present invention, the flow control rules are managed and displayed according to the flight direction, allowing the flow room controller to search and grasp the flow control rules in each flight direction, and the operation is very simple and convenient. Moreover, in the embodiment of the present invention, the display characteristics corresponding to each flow control rule are set, and the flow room controller can filter according to the flow control rules, so that the flow room controller can see the flow-controlled flights in the current air flight situation at a glance. It is no longer necessary to manually filter and display controlled flights one by one, which greatly improves the daily work efficiency of flow room controllers and reduces the probability of errors in daily work.

In the embodiment of the present invention, the warning prompt includes: a signboard warning prompt of two flights whose interval does not meet the requirements of the flow control rule, and the two flights are automatically connected and the time difference and distance between the two flights are displayed. The signboard warning prompt includes the signboard automatically flashing or displaying special warning characters (the content and color of the warning characters are configurable).

In order to better understand the technical solution of the alarm in the embodiment of the present invention, the following examples are listed:

The required interval for setting traffic control rules is: 2 flights every 30 minutes after landing at Chongqing Airport, with a minimum interval of 10 minutes. If there are two flights landing at Chongqing Airport in the air at this time, both flights satisfy the same flow control rule, but the time interval between the two flights is 8 minutes, then the time between the two flights If the interval is less than 10 minutes required by the flow control rules, an alarm will be automatically given on the signs of the two flights to remind the traffic room controller to take corresponding control measures and increase the time interval between the two flights. .

The embodiment of the present invention also includes: for multiple flights that comply with the same flow control rule, the time difference and distance between two flights in the multiple flights are calculated, and it is determined whether the time difference and distance are about to fail to meet the interval required by the flow control rule. If the time difference and distance are about to fail to meet the interval required by the flow control rule, an early warning prompt is issued. Among them, judging whether the time difference and distance are about to fail to meet the interval required by the flow control rule may include: judging whether the time difference and distance are greater than 1.1 times the interval required by the flow control rule. Specifically, for multiple flights that comply with the same flow control rule, the time difference and distance between two flights in the multiple flights are calculated, and it is determined whether the time difference and distance are greater than 1.1 times the interval required by the flow control rule. If not, an early warning prompt is issued.

The existing ATC system mainly assists air traffic controllers to dynamically monitor and command aircraft in the air to prevent dangerous approaches between aircraft, prevent aircraft from colliding with ground targets, and prevent aircraft from entering dangerous areas. The corresponding alarm functions are mainly They are conflict alarms, low and high alarms, dangerous zone alarms, etc. The alarm function of the ATC system is very important, but it is not a function that the flow room controller needs. The embodiment of the invention can promptly remind the flow room controller that the time and distance intervals between controlled flights do not meet the requirements of the flow control rules, so that the flow room controller no longer needs to monitor and calculate the time and distance intervals between controlled flights by himself. Whether the requirements of the flow control rules are met, the alarm will automatically remind the flow room controller to take corresponding measures as early as possible, which greatly facilitates the daily work of the flow room controller.

S1, set flight flow control rules, classify and manage the flow control rules according to flight directions, such as Kunming, Xi'an, Lhasa, Nanning, Guangzhou and other directions. Multiple flow control rules can be set under each flight direction;

S2, setting the display characteristics corresponding to each flow control rule; for a flight that meets a certain flow control rule, automatically displaying the flight sign according to the display characteristics corresponding to the flow control rule;

S3: For multiple flights that comply with the same flow control rule, calculate the time difference and distance between two flights in the multiple flights, and determine whether the time difference and distance meet the interval required by the flow control rule. If not, issue an alarm prompt.

In the embodiment of the present invention, flight flow control rules can be set, and the flow room controller can manage according to the flight direction, which is simple and convenient to operate; display features corresponding to the flow control rules are also set, and the flow room controller can filter the corresponding flights as needed. , improves work efficiency and reduces the probability of errors; it can also determine whether the intervals between multiple flights that comply with the same traffic control rule meet the requirements of the traffic control rule, and issue an alarm prompt if they do not meet the requirements.
