Description
Technical Field
[0001] The present invention belongs to the technical field of aircraft radar training systems, and in particular relates to a civil aviation aircraft radar simulation device, a training system and a training method. Background Art
[0002] Current civil aviation maintenance training for specific aircraft types, particularly regarding aircraft radar systems, which are crucial for aircraft maintenance, suffers from a significant lack of experiential learning. The mainstream model still relies heavily on static text descriptions in technical manuals, theoretical explanations in standard textbooks, and physical comparisons using retired aircraft. These traditional methods certainly provide basic knowledge and structural cognition, but they are seriously deficient in presenting the complex working principles, dynamic interaction processes and realistic operating environments of radar systems. They cannot vividly demonstrate key abstract concepts such as radar beam scanning characteristics, target detection and tracking logic, dynamic display of weather echoes, and multi-system collaborative working mechanisms. It is even more difficult to simulate the entire process of how pilots observe, interpret radar echo information and make decisions when facing various complex weather and airspace scenarios in a real cockpit environment. What is particularly prominent is that in the face of the need for maintenance personnel to have an in-depth understanding of the practical aspects of radar system ground testing, fault diagnosis, calibration and maintenance, existing training methods can hardly provide any 1:1 full-scale simulation teaching platform that can highly restore the real cockpit environment; The present invention uses virtual simulation technology to explain the working principle and a real simulated cabin to train students on the actual operation process, and combines the two to achieve virtual-real interaction. Summary of the Invention

The simulated B737NG cockpit includes a B737NG flight simulator, a B737NG radar function panel, an embedded signal acquisition board, and a flight LCD panel simulation display. The embedded signal acquisition board can collect real-time information about the trainee's actual cockpit operations and upload the signals to the virtual simulation host via a bus communication module.

[0016] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.
[0017] like Figure 1-6 As shown, a civil aircraft radar simulation device of the present invention includes: The computer main structure, including a standard cabinet, a virtual simulation host and a bus communication module, can simulate actual faults and check whether the operation is correct. It can also output simulation images to the outside world and simulate the environment inside and outside the cabin to enhance the authenticity of the virtual simulation. By using virtual simulation technology, the main inspection processes and key operating points required for ground maintenance of the B737NG model can be presented through virtual simulation. It can also simulate uncommon faults in actual work and check whether the corresponding operations are correct, thereby improving the skills of trainees. At the same time, this module, as the host, can output virtual images to external displays, including the virtual simulation visual display system and the built-in LCD display of the B737NG simulated cockpit. It can simulate from the outside environment to the inside environment, thereby improving the authenticity of the virtual simulation and simulating the actual operation environment and uncommon abnormal situation scenarios.
[0018] The simulated B737NG cockpit includes a B737NG flight simulator, a B737NG radar function panel, an embedded signal acquisition board, and a flight LCD panel simulation display. The embedded signal acquisition board can collect real-time information about the trainee's actual cockpit operations and upload the signals to the virtual simulation host via a bus communication module. The flight LCD panel simulation display is connected to the simulation host via an HDMI video cable to receive images of the cabin's LCD instruments generated by the host and display the corresponding data content. The built-in embedded acquisition board can collect the trainees' actual operations on various panels in the cabin in real time, and can upload the signals to the host through the data bus. The built-in LCD screen is connected to the host through an HDMI video cable, and can receive the images of the LCD instruments in the cabin generated by the host and display the corresponding data content. The use of a physical simulation cabin can allow trainees to truly experience the actual working environment without a real machine environment. The physical simulation cabin can help trainees better adapt to future working conditions and quickly find the actual areas that need to be operated in the complex real machine cockpit. The real operating experience cannot be replaced by pure virtual touch. Real maintenance operations require blind control to find the panel that needs to be operated, combined with multi-point control and simultaneous observation of the cabin display. Pure touch cannot achieve this at all. The use of a physical operation interface avoids this shortcoming.
[0019] Simulate B737NG airborne radar, including: B737NG airborne radar model; The motion control servo system can receive signals sent by the virtual simulation host on the bus communication module. The motion control servo system can drive the B737NG airborne radar model to rotate, thereby simulating the motion posture of the real aircraft radar; A movable display stand is used to carry the motion control servo system and the B737NG airborne radar model.
[0020] By receiving signals from the host computer on the bus, the servo module drives the onboard radar model to rotate, simulating the motion of a real aircraft radar. This physical simulation, combined with the virtual cabin simulation, helps trainees understand the corresponding radar status during ground maintenance operations and deepens their understanding of the relationship between the cabin data display and the actual radar panel.
[0021] The virtual simulation visual display system mainly uses a 75-inch LCD display, which receives the virtual simulation images sent by the virtual simulation host through the HDMI interface and can simulate the situation outside the cockpit.
[0022] The display can receive virtual simulation images sent by the host through the HDMI interface, and can simulate the situation outside the cockpit, including abnormal personnel intrusion, ground personnel's command and other scenarios, forming a complete work scene simulation with the operations inside the cabin, reducing the dependence of maintenance personnel training on the real airport environment and corresponding aircraft models. It is a low-cost, high-simulation training method that is repeatable and can be upgraded according to the latest training content, with strong upgrade and iteration space.
[0023] like Figure 7-8 As shown, a ground cognitive training system is built into a virtual simulation host of a civil aircraft radar simulation device; The ground cognitive training system includes: The data processing unit is used to read the trainee's actual operation and generate corresponding response feedback based on the operation, including virtual images, simulated physical movements, and lighting response effects of the simulated cabin, forming a good closed-loop feedback loop with the trainee; Aviation training question banks and training syllabi, including updateable question banks and training syllabi, are closely related to the ground radar training content for the B737NG aircraft. The system can read the training syllabus in real time and generate training content based on the syllabus to prevent training from becoming outdated. Training assessment content can be generated based on the latest question bank. The data management and analysis module can record the historical operation records of different trainees, which can be used for training content generation, performance assessment and teaching upgrade analysis.
[0024] The intelligent training content generation module can intelligently generate targeted training and assessment content based on the aviation training question bank, training outline and historical data of trainees. It can also comprehensively generate personalized training content suitable for individual trainees based on their learning progress, past performance levels and historical errors, thus achieving differentiated and personalized training.
[0025] A training method comprising: S1: Divide the aviation training question bank into multiple question bank intervals according to the content scope. Students select the question bank intervals they need to learn according to different majors. Generate the training learning scope according to the learning progress and further select the question bank intervals. S2: Set multiple different score ranges, set the degree of increase or decrease in the number of questions to be answered in different score ranges, match the past score level with the score range, and calculate the number of questions to be answered for the corresponding training; S3: Lock the target question bank interval based on historical errors, first extract a fixed number of answers within the error question bank interval, and then randomly extract answers within the training learning range based on the number of remaining training questions; S4: Generate a personal comprehensive training question bank.
[0026] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed herein are intended to be covered by the claims of the present invention.
