Description
Technical Field
The invention relates to the field of air traffic control, in particular to an enhanced control instruction support system and a method thereof based on user attention focus perception, wherein the enhanced control instruction support system collects user attention focus information, and combines with conventional instruction support analysis data to analyze and process to obtain more accurate control instruction support information according with actual conditions.
Background
Air traffic control is an extremely important part in the civil aviation operation process, and a controller issues a control instruction corresponding to the current air traffic situation so as to ensure the air traffic safety operation, however, the problem of control instruction error or deviation is easy to occur through the mode of manually judging the instruction, and further the problem of system air operation safety is caused. Currently, in response to the above-mentioned problems, organizations have begun to develop some regulatory instruction support systems to assist the regulators to send the regulatory instructions more accurately.
The current regulatory instruction support system is mainly divided into a regulatory instruction monitoring prompt system and a regulatory instruction suggestion system: the control instruction monitoring and prompting system monitors whether a control instruction issued by a controller causes a potential instruction error or an instruction error condition in real time, and when the control instruction is possibly wrong or has a mistake, an instruction prompt and an alarm are sent; the control instruction suggestion system combines the traffic operation dynamic and various factors (such as controller preference, airport operation limitation, airspace operation limitation, airline preference and the like) to send out appropriate control instruction suggestions for the controller to refer to.
However, the current instruction support system still has some disadvantages:
1. the auxiliary effect of the control instruction monitoring/prompting/alarming system is poor:
in conventional policing guidelines, when the support system detects a potential conflict situation or an actual conflict situation, the support system may prompt an alarm prematurely if set too sensitively, or the support system may alarm because the user has not resolved the conflict in a particular way (at which time the user has otherwise resolved the conflict). For the user, if the support system prompts an alarm in advance or has more unnecessary prompts, the user easily thinks that the support system gives too many false alarms or false prompts, which causes the trust of the user on the support system to be reduced, even directly neglecting the prompts and alarms. For example, some users may actually be aware of the conflict and prepare to make a deployment at a later time, and the support system may alert that the user is unaware of the conflict, or some user may prepare to deploy using the a-plan at a later time, but the system may alert that the user is not deploying using the B-plan. The frequent occurrence of these situations causes the user experience to be extremely reduced, and the support system cannot be fully utilized.
Meanwhile, if the system is set to be more likely to conflict, an alarm is prompted, and the function of the control instruction monitoring system is not fully exerted.
2. The instruction suggests system deficiencies:
the user can adopt various allocation modes according to different traffic dynamics during the conventional command allocation. If the support system directly generates a plurality of allocation modes, the scheme which can be selected by the user is too many, the user needs to spend more energy for selection, the energy is consumed, and the control command is influenced. On the other hand, when the support system predicts the user's solution according to some manner to reduce the recommended solution, if the support system does not accurately learn or predict the manner in which the user wishes to make the solution, the generated solution may not necessarily conform to the manner desired by the user, and the user may be disturbed to some extent from thinking about the solution, affecting the control command.
In summary, the above mentioned situations all result in that the regulatory instruction support system cannot be widely popularized in practical applications, or the support system can primarily assist the instruction system, but the actual situation of assistance is not optimistic.

For convenience of description, the enhanced regulatory instruction support system based on the user attention focus perception is referred to as the enhanced regulatory instruction support system based on the user attention focus perception, and the enhanced regulatory instruction support system based on the user attention focus perception have no difference in meaning, and the enhanced regulatory instruction support system adopts an enhanced regulatory instruction support method based on the user attention focus perception for regulation.
As shown in fig. 1, the enhanced regulation instruction system is in communication with a conventional instruction support device 20, and includes an attention focus device 10 and an analysis processing device 30, where the attention focus device 10 is used to collect an attention focus of a user to obtain attention focus information, the conventional instruction support device 20 may be any type of conventional instruction support device to collect conventional regulation instruction support information, and the analysis processing device 30 is in communication with the attention focus device 10 and the conventional instruction support device 20 to respectively obtain and analyze the attention focus information and the conventional regulation instruction support information to obtain enhanced regulation instruction support information.
Correspondingly, the enhanced regulatory directive support method based on the perception of the user attention focus is communicated with a conventional directive support system, and comprises the following steps:
s1: acquiring attention focus information of a user;
s2: acquiring conventional control instruction support information obtained by a conventional instruction support system in real time; and
s3: and analyzing and processing the focus-of-attention information and the conventional control instruction support information to obtain enhanced control instruction support information.
Wherein the general regulation instruction support information in the step S2 includes, but is not limited to, one or more of the following information: potential conflict information, instruction reminder information, instruction alert information, instruction suggestion information, and their source data information. Since the conventional policing instruction support information is well known in the prior art of air traffic control, that is, the conventional instruction support apparatus 20 is a common apparatus system, it is not described here too much in detail.
Specifically, in step S1, two scenarios are subdivided: one is to acquire the focus of attention of the user in the area/approach control work scene, and the other is to acquire the focus of attention of the user in the tower control work scene.
When the focus of attention of the user is obtained in the area/approach control work scene, the controller mainly needs to pay attention to the target information of each target in the main control device, wherein the target information of the target includes, but is not limited to, the position, the heading, the speed, the interval between each target and other information of each target, and meanwhile needs to pay attention to the influence information on the displays of some other devices, such as important element information displayed on the display of the meteorological device and important element information in the prompt display device of the important information, if necessary.
In this case, the gaze focus information acquisition may be achieved by one or more of the following:
1. operation information of a user in a radar automation system:
when implementing the regulatory command, the user conventionally needs to perform a selection click or other operation on each target in the radar automation system by using an interactive device (touch screen, mouse), and the information is defined as operation information, such as marking a distance connecting line between two targets or performing habitual operation according to an individual user, wherein the habitual operation of the user learns information such as habitual operation or unintentional operation when the user focuses on a certain target by collecting operation habits of each individual user through big data.
2. User sign information:
2.1 collecting sign information by using high-definition camera
The method comprises the steps of tracking the eye attention point information of a user in real time by using a high-definition camera arranged on the side of the main control equipment, wherein the eye attention point information comprises but is not limited to the position aligned with the center of an eyeball and the change characteristic information of the pupil when the user starts to watch a target, and converting the information into the coordinate information of the eye attention point of the user on the main control equipment.
2.2 utilize intelligent glasses to gather sign information:
by using the intelligent glasses, the camera device arranged on the glasses acquires the gaze and attention point information of the user in a manner similar to the manner described in 2.1, and analyzes and converts the gaze and attention point information into coordinate information of the eyeball and attention point of the user on the main control equipment.
In this way, the operation of the user on the radar automation system and the focus attention position of the user are acquired, so that the focus attention information of the user can be known. For example, if the attentive point of the user a is located at the position a, it is known that the attentive focus of the user is focused at the position a.
In the tower control work scenario, the tower controller focus is not limited to the primary control device, but includes a plurality of displays including, but not limited to, a weather information display and an electronic flight control system (or a conventional flight control), individual aircraft real-time dynamics, airport runways, and air space taxiway ramps associated with the runways.
For the above-mentioned contents of interest, the tower controller needs to give scanned attention to the above-mentioned contents, and needs to give more important attention to specific contents of interest in specific cases. Such as giving important attention during the takeoff and running of the aircraft, landing of the aircraft, potential or actual operational conflicts between aircraft, or ensuring that attention is paid to the changing content on the weather information display when the weather information changes.
The attention content can be acquired by one or more of the following ways:
1. the intelligent glasses worn during the command are utilized to collect attention information:
the intelligent glasses can utilize the camera device to learn the video scene in front of the glasses, which is overlapped with the visual angle of the user, or deduce the target observed by the user according to the spatial position and the azimuth visual angle of the user. Or the horizontal and vertical positions and the specific horizontal and vertical orientations of the glasses in the space range can be known and converted into the eye-sight focus point information of the user by utilizing a horizontal and vertical measuring instrument in the glasses and combining a specific device, such as a device which is arranged on the ceiling or the ground and matched with the glasses and measures the position of the glasses in the space range.
Additionally, the above scheme can be improved as follows
1.0.1：
The movement information of the eyeball is tracked by using the tracking imaging device for the eyeball in the glasses like the above, so that the position information of the eyeball relative to the glasses and the characteristic information of the pupil change when the eyeball focuses on the target are obtained.
1.0.2：
And corresponding sensing equipment, such as an infrared device, is also arranged on each display device, and when the corresponding visual angle of the glasses and the display surface of the sensing equipment on each display device are intersected with a set rule and the duration is longer than a set value, the attention focus point information is acquired.
2. Sign information is collected and tracked by utilizing front-facing camera device in equipment
When paying attention to equipment such as a radar automation system and an electronic process list system, a user tracks physical sign information by means of a front-facing camera on the equipment and records the physical sign information as attention point information, which is similar to the content introduced before.
3. Collecting and tracking sign information by one or more cameras in working scene
The physical sign information of the tracked user is acquired by the camera device, and the specific mode is similar to the content introduced before.
The basic principle is that the position of a worker in a workplace and the visual angle height (height corresponding to eyeballs of the worker) of the worker are obtained by a plurality of camera devices in the workplace, the visual angle (horizontal angle and vertical angle) corresponding to the observation of an object by the worker and pupil change characteristic information or other physical sign information when the user starts to focus on the object are obtained by another camera, and the angle aligned with the center of the eyeballs of the worker in the space is obtained and analyzed and converted into the coordinate information of the attention point of the eyeballs of the user in the space.
4. With tracking operation information of a user on the display device:
tracking user operation information in radar automation system, tower electronic process list, tower traditional process list, weather display device and other devices
In other words, the step S1 further includes the steps of:
s11, acquiring operation information of a user on the radar automation system, wherein the operation information comprises but is not limited to selection information and habitual operation information of the user on the radar automation system;
s12: acquiring sign information of a user, wherein the sign information comprises eye attention point information of the user; and
s13: and analyzing the sign information and/or the operation information to obtain the focus of attention information of the user.
In some cases, the step S11 requires obtaining the operation information of the user on an auxiliary display device, wherein the auxiliary display device includes, but is not limited to, a weather information display and an electronic flight control system (or a conventional flight control unit), each aircraft real-time dynamic state, an airport runway, and an airspace taxiway apron associated with the runway, and correspondingly, the physical sign information includes the attention content of the user on the auxiliary display device, wherein the attention content shows whether the user pays attention to the auxiliary device. The specific data acquisition manner for the step S11 and the step S12 has been described in the previous example, and is not specifically expanded here.
Correspondingly, the focus of attention device 10 includes an operation information obtaining device 11, a sign information obtaining device 12, and a focus analyzing device 13, where the operation information obtaining device 11 obtains operation information of a user on the main control device and/or the auxiliary device, the sign information obtaining device 12 may be an intelligent glasses capable of obtaining information of a focus of attention, and the focus analyzing device 13 is communicatively connected to the operation information obtaining device 11 and the sign information obtaining device 12 to obtain the operation information and the sign information, and analyzes to obtain focus of attention information of the user.
Specifically, the focus analysis device 13 analyzes the feature information and the operation information in the following ways, which may include the following ways:
1. analysis processing on the operation information:
for the operation information on the primary control device, the user can be shown to pay attention to the corresponding target area according to the modes of clicking the target by a user mouse, marking the corresponding area by the user, amplifying and reducing the corresponding area by the user, marking some targets by the user (such as marking conflict connection lines), and the like.
Furthermore, the target area concerned by the user can be obtained according to big data (analyzing and processing various operations and concerned contents consciously or unconsciously by the user).
2. And (3) analysis processing of sign information:
the physical sign information collected by the camera device is mainly analyzed and processed according to the collected content to obtain the position of a point concerned by a user and an event which starts to be concerned:
according to the camera device analysis: a1. aligning the eyeball with the position; a2. eyeball attention starting target feature information (such as pupil change features when the glasses start to pay attention to the target) and a3. attention degree (attention time and glasses focus degree) are obtained according to the b1. position coordinates of the user attention point/area and b2. attention focus degree b3. attention time.
Namely, the focus analysis device 13 is in communication with the operation information acquisition device 11 and the physical sign information acquisition device 12, and acquires the gaze attention point information and the attention content of the user according to the above manner, and since the attention content can be directly acquired, excessive description is not given here.
In addition, in the step S3, the analysis processing device analyzes the focus of attention information and the general regulation instruction support information, where the general regulation instruction support information includes an instruction area of an instruction user, the analysis processing device compares the instruction area with the focus of attention information, and when the focus of attention information does not coincide with the instruction area, the analysis processing device adjusts the general regulation instruction support information according to the focus of attention information to obtain the enhanced regulation instruction support information.
The setting manner of adjusting the conventional instruction support information to the enhanced regulation instruction support information may be as follows:
1. run conflict/hint type instruction support information:
the conventional operation conflict/prompt instruction support information is mainly obtained by analyzing conflict information between the aircraft and the aircraft in an operation area and between the aircraft and other obstacles and areas;
2. run conflict/hint information
The operation conflict information mainly refers to information that the aircraft is potentially separated from other aircraft by less than a specified value.
The conventional instruction support system analyzes and judges the operation conflict information between the aircrafts according to the analysis of the actual predicted position information of the aircrafts and other related information, and the operation conflict information can be converted into each conflict point information with coordinate information.
The analysis processing device of the invention unifies the eye attention point information and the conflict information, when a certain conflict point is observed by a user in a form exceeding a certain attention degree, the conflict point can be inferred to be observed according to a set form, and the enhanced control instruction support information can not take the information as enhanced operation conflict information.
A1 for example, when the conventional command support system learns that an X conflict point is formed between the a aircraft and the B aircraft, and the system learns that the user has performed gaze attention for more than 1s for a plurality of times at the X conflict point, it is inferred that the user has focused on the X conflict point, and the enhanced command support information may not be used as the enhanced operation conflict information when generated.
A2 for example, when the conventional command support system learns that a aircraft is sliding from a taxiway outside the runway toward the runway area (which would be conventionally required by the aircraft) with a tendency to approach greater than a conventional value, the active area of the a aircraft will be a significant point of interest, and when the aircraft is continuing to approach the runway area and the distance is less than a set point, a prompt will be issued. However, when the enhanced command support system observes that the user keeps continuously paying attention to the aircraft for an interval of not less than 2s, it is inferred that the user has paid attention to the X conflict point, and when the enhanced command support information is generated, the information may not be regarded as enhanced operation conflict information.
3 instruction suggestion information
The conventional instruction support system generates a suggested instruction of a deployment scheme according to various traffic operation information, and after the user point of interest information is combined, the system can obtain the point of interest focused by the user and the deployment scheme corresponding to the point of interest, and accordingly selects the scheme corresponding to the point of interest.
For example, in a deployment scenario consisting of A, B conflict sets, to deploy the scenario, the user can resolve the conflict set by resolving the conflict a, and can also resolve the conflict set by resolving the conflict B. When the command enhancement system learns that the user has explicitly focused on the A conflict, it may be set that it prefers deployment by resolving the A conflict, and the enhanced command system prefers the scheme to provide it with a set of deployed A conflict-resolved conflicts.
The present invention is not limited to the above-mentioned preferred embodiments, and any other products in various forms can be obtained by anyone in the light of the present invention, but any changes in the shape or structure thereof, which have the same or similar technical solutions as those of the present application, fall within the protection scope of the present invention.
