Description

Technical Field

[0001] The present invention relates to the technical field of aircraft wheel maintenance, and in particular to an aircraft wheel brake monitoring system and method. Background Art

[0002] As an important component of the aircraft landing gear, aircraft wheels support and reduce shock when the aircraft is parked, taxied, taking off or landing. For damage that does not exceed the standard, if there is no effective monitoring, it is easy for the damage to worsen or even exceed the standard but not be discovered in time. Repeated confirmation of damage during route operation is likely to cause flight delays and economic losses. If the wheel has excessive damage, it is very easy to cause tire blowouts, air leaks, etc. If these situations occur when the aircraft is taxiing at high speed, it will seriously affect flight safety, and at best, it will run off the runway, and at worst, the aircraft will be destroyed and people will die. At present, most airlines use oil-based markers to directly mark the tire side corresponding to the damaged part of the tire when monitoring aircraft wheel damage.

[0003] Regarding tire pressure, many airlines do not have the option of installing tire pressure sensors, and the tire pressure values ​​obtained during tire pressure measurement are recorded on paper work cards.

[0004] Regarding the remaining life of the brakes, there are only brake indicator pins on the aircraft, but no sensors. The remaining length of the brake indicator pins measured during the inspection (indicating the remaining life) is also only recorded on the paper work card.

[0005] Disadvantages of existing technology:

[0006] 1. Use an oil-based marker pen to mark the wheel directly. As the wheel wears more or the side wears, the mark will be lost easily.

[0007] 2. Only by seeing the actual wheel can we determine whether there is any damage record for the wheel.

[0008] 3. Due to the lack of relevant information such as the time and location of the injury, the specific injury size, and the injury standard, it is impossible to further analyze the injury data.

[0009] 4. Regarding tire pressure, many airlines do not have the option of installing tire pressure sensors, and the tire pressure values ​​measured are recorded on paper work cards, which make it impossible to quickly query and perform data analysis to monitor whether the tire has potential failures such as excessive leakage rates.

[0010] 5. Regarding the remaining life of brakes, there are only brake indicator pins on the aircraft, but no sensors. Information such as which brakes currently installed in the fleet are about to reach the replacement threshold, that is, the remaining life is close to zero, cannot be obtained, so it is impossible to extract brake life information for flight adjustments, and replacement may be required during operation, resulting in flight delays.

[0011] In view of this, the inventor has designed a system and method that can digitally record and monitor wheel damage, tire pressure, and remaining brake life. Summary of the invention

[0012] The purpose of the present invention is to provide a wheel brake monitoring system and method. By establishing this system, wheel damage, tire pressure, and remaining brake life can be digitally recorded and monitored, data can be analyzed, and airports with high puncture rates can be identified, so that corresponding management and control measures can be formulated. The leakage rate of tires within a certain period can be monitored, and defective tires can be replaced in advance. The situation of abnormally short brake life can also be identified, thereby identifying potential system failures, preventive troubleshooting to eliminate unsafe incidents such as tire blowouts caused by system failures, and flight adjustments can be made in advance, and brake components with a life close to zero can be replaced in an orderly manner, reducing temporary replacements during operation and avoiding flight delays.

[0021] Furthermore, the wheel damage recording module includes a CAD-assisted positioning module, which is used to establish a two-dimensional coordinate model according to different wheels of different models. The model takes the aircraft tire valve core axis as the origin and is marked 360° clockwise at intervals of 10°, and based on the CAD two-dimensional graphics, a tire contour map and a tread expansion map with the aforementioned marking degrees are obtained. The damage mark can be marked once or twice on the tire contour map and the tread expansion map, respectively, to locate the circumferential position and axial position of the damage, respectively. The tire contour map and the tread expansion map with the aforementioned damage mark are linked to the wheel information summary page.

[0022] Furthermore, the mobile terminal includes an AR auxiliary positioning module, which is used to call the camera of the mobile terminal to capture a real-time wheel image and align it with a tire contour map with a circular scale to achieve circumferential auxiliary positioning of wheel damage.

[0023] Furthermore, the wheel damage recording module includes a damage auxiliary judgment module, in which the damage standards corresponding to the tire manufacturer and tire model are pre-recorded in the wheel damage monitoring module.
