Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In the description of the specification and claims, it should be understood that the terms first, second, etc. are used solely for the purpose of distinguishing between similar features and not necessarily for the purpose of describing a sequential or chronological order, and not necessarily for the purpose of indicating or implying a relative importance or implicitly indicating the number of features indicated. The terms are interchangeable where appropriate. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include at least one such feature.
The aircraft radio navigation is to measure navigation parameters such as azimuth, distance, speed and the like of an aircraft by utilizing the propagation characteristics of radio waves, calculate the deviation between the aircraft and a specified route, and operate the aircraft by an aircraft pilot or an autopilot to eliminate the deviation, so that the aircraft is kept on the specified route, and therefore, the aircraft radio system can cause the aircraft to fail to operate normally when the aircraft fails, and the troubleshooting work is needed in time.
At present, reasons for the failure of the aircraft radio navigation system mainly comprise external environment interference, configuration influence of the aircraft radio navigation system and faults of the aircraft equipment, and in the embodiment of the invention, the configuration influence of the aircraft radio navigation system and the faults of the aircraft equipment are collectively called as faults of the radio navigation system. In the prior art, external environment interference and faults of a radio navigation system cannot be well distinguished, once fault data occur, the reason that the aircraft radio navigation system cannot work normally is further determined through isolation and troubleshooting, and a large amount of time and resource cost are consumed in the process.
Referring to fig. 1, a flow chart of steps of an troubleshooting method of an aircraft radio navigation system according to an embodiment of the invention is shown. In this embodiment, the troubleshooting method of the radio navigation system of the aircraft is specifically performed by steps S1 to S5:
s1, acquiring QAR data of an aircraft fleet, and obtaining data when GPS of each aircraft in the fleet is lost or GPS precision is degraded, wherein the data is used as fleet abnormal data.
It can be understood that the situation that the radio navigation system of the airplane cannot work normally due to the interference of the external environment has the space-time aggregation characteristic, and the space domain which interferes with the radio navigation system of the airplane can be accurately positioned by acquiring the QAR data of the aircrew and analyzing the aircraft data of the whole aircrew of the aircrew.
Preferably, in the embodiment of the present invention, after step S1, the fleet anomaly data can also be displayed on a map, and the data when the GPS of the aircraft of different times and/or different models is lost or the GPS accuracy is degraded can be checked by searching according to the time and the tail number of the aircraft.
S2, acquiring fault data of a radio navigation system of the aircraft to be troubleshooted; the radio navigation system includes GPWC systems.
It should be noted that the radio navigation system includes GPWC system (Ground Proximity Warning Computer, enhanced near-earth warning system) by way of example only, and in practical application, the radio navigation system may further include at least one of a GPS positioning system, TCAS system (Traffic Collision Avoidance System, air traffic warning and collision avoidance system), LRRA system (Low Range Radio Altimeter, low-altitude radio altimeter), ADIRU system (AIR DATA INERTIAL REFERENCE Unit, air data and inertial navigation system), ILS system (Instrument LANDING SYSTEM ), VOR system (VHF Omnidirectional Range), ATC antenna (AIR TRAFFIC Control) and DEM range finder.
S3, judging whether fault data of GPWC systems of the aircraft to be troubleshooted are matched with abnormal data of the fleet or not; if yes, executing step S4, otherwise executing step S5.
S4, judging that the environment is disturbed to cause faults.
S5, judging that the radio navigation system of the aircraft to be discharged has faults.
In the scheme, the operation data of the aircraft, namely the abnormal data of the aircraft fleet, can be obtained by acquiring the QAR data of the aircraft fleet under the condition of radio interference; and matching the fault data of the GPWC system of the aircraft to be eliminated with the abnormal data of the fleet, if the fault data of the GPWC system of the aircraft to be eliminated can be successfully matched, the fault of the aircraft to be eliminated is caused by external radio interference, otherwise, the fault of the radio-electric system is caused. By adopting the embodiment of the invention, the flight data of the whole fleet can be analyzed, the faults of the aircraft to be eliminated are automatically distinguished to be caused by the external environment or the faults of the aircraft equipment body, the complex isolation and elimination work of the aircraft under the condition of external interference is avoided, and the time cost and the maintenance cost are greatly reduced.
As a preferred embodiment, step S1, acquiring QAR data of an aircraft fleet, and obtaining data when GPS of each aircraft in the fleet is lost or GPS accuracy is degraded, as fleet anomaly data, specifically, executing through steps S11 to S12:
s11, acquiring QAR data of the aviation fleet.
S12, according to the QAR data, extracting and obtaining time points when GPS loss or GPS precision degradation occurs to each aircraft in the fleet, and position, altitude, heading and speed data of the aircraft under the time points as fleet abnormal data.
It should be noted that, the time point is not an accurate absolute time, in the embodiment of the present invention, the take-off time of the aircraft can approximately reflect the airspace in which the aircraft is located because the route of the aircraft is relatively fixed, and in practical application, the take-off time can also be calculated from the time point when the aircraft begins to slide, which does not affect the beneficial effects obtained by the present invention.
In the above scheme, since the current GPS signal is relatively stable, when the GPS loss or the GPS precision degradation occurs in the aircraft, the current GPS signal can be considered to be the external signal interference, and the position, altitude, heading and speed data of the aircraft at the time point can be combined with the time point when the GPS loss or the GPS precision degradation occurs in the aircraft, so that the flight airspace and the flight state of the radio navigation system of the aircraft when the radio navigation system of the aircraft is interfered by the external signal can be represented.
Further, as a preferred embodiment, step S3 is executed to determine whether the fault data of GPWC systems of the aircraft to be troubleshooted matches the fleet anomaly data, specifically through steps S31 to S33:

And S33, judging that the fault data of the GPWC system of the aircraft to be troubleshooted is not matched with the abnormal data of the fleet.
It should be noted that, the influence of the external environment on the radio navigation system of the aircraft may be due to reflection, attenuation or multipath propagation of signals caused by topography and topography; electromagnetic interference may also be generated by other radios, radars, communication devices, etc.; it is also possible that certain equipment or weather phenomena produce electromagnetic radiation or severe weather conditions that affect radio signal transmission, these effects having spatio-temporal aggregation characteristics, typically occurring in fixed air spaces. By monitoring the distance between the aircraft and the ground, the GPWC system generates fault data when the GPWC system monitors that the aircraft is approaching the ground, that the aircraft is at an abnormal altitude, that the terrain surrounding the aircraft is changing, that the aircraft glide angle is abnormal, that the aircraft speed is abnormal, or that the aircraft GPS signals are abnormal.
In the above scheme, when the time point, the position, the altitude, the course and the speed data of the fault data of the GPWC system of the aircraft to be troubleshooted are consistent with the abnormal data of the fleet, the GPS signal abnormality of the aircraft can be judged to be the fault caused by the external environment interference.
Preferably, the radio navigation system further comprises a TCAS system, and after determining that the radio navigation system of the aircraft to be troubleshooted has a fault in step S5, the troubleshooting method of the radio navigation system of the aircraft further comprises steps S511 to S512:
S511, when the fault data of the radio navigation system of the aircraft to be troubleshooted comprises the fault data of the TCAS system, determining that the aircraft to be troubleshooted has the TCAS fault.
It should be noted that, when the fault data of the radio navigation system of the aircraft to be troubleshooted includes the fault data of the TCAS system, it is indicated that the TCAS system may not accurately detect the positions and distances of other aircraft due to communication faults, self-checking failures, and the like, so that collision may occur during the flight.
S512, judging that the fault of the aircraft to be eliminated is an antenna fault or a computer fault according to the fault data of the TCAS.
For example, when the fault data of the TCAS system includes a fault code or warning information related to the antenna, determining that the fault of the aircraft to be troubleshooted is an antenna fault; when the fault data of the TCAS system comprises no response of the system, automatic restarting or sending out a warning signal related to a computer, the fault of the aircraft to be eliminated is judged to be the computer fault.
Preferably, the radio navigation system further comprises LRRA a system, and after determining that there is a fault in the radio navigation system of the aircraft to be troubleshooted in step S5, the troubleshooting method of the radio navigation system of the aircraft further comprises steps S521 to S522:
S521, when the fault data of the radio navigation system of the aircraft to be troubleshooted comprises the fault data of the LRRA system, judging that the aircraft to be troubleshooted is a landing gear configuration defect fault or a radio fault.
It should be noted that the LRRA system of the aircraft measures the altitude of the aircraft by transmitting and receiving radio signals, which can provide an accurate distance between the aircraft and the ground, and help the pilot to grasp the altitude information of the aircraft. When the LRRA system generates fault data, it may be that the LRRA system fails due to radio failure of the aircraft, or that the inherent reliability of the equipment selected for use by the radio system of the aircraft is different, i.e., a landing gear configuration defect failure.
S522, judging the position of the failed transceiver or antenna according to the fault data of the LRRA system.
It will be appreciated that the location of the failed transceiver or antenna is determined by the type of failure, time of occurrence of the failure, failure mode, etc. indicated in the failure data of the LRRA system, which may be an antenna failure or a failure caused by a failure of the transceiver mechanism type.
As a preferred embodiment, the radio navigation system further includes LRRA, and after determining that the radio navigation system of the aircraft to be troubleshooted has a fault in step S5, the troubleshooting method of the radio navigation system of the aircraft further includes steps S531 to S533:
S531, screening out jump data with low-altitude data jump from fault data of LRRA systems of the airplanes to be eliminated.
S532, according to the jump data, the jump probability distribution and jump geographical position data of the radio altitude systems with different piece numbers are obtained through analysis.
S533, analyzing the reliability of the aircraft to be discharged according to the jump probability distribution and the jump geographic position data.
In the above scheme, when the low-altitude data jump occurs in the fault data of the LRRA system, the problems that a sensor fault, external signal interference or power supply fault and the like possibly occur are described, and according to the jump probability distribution and jump geographical position data of the radio altitude systems with different piece numbers obtained by the jump data, the jump probability distribution and jump geographical position data can be used as a data source for reliability analysis of an aircraft, and by carrying out the reliability analysis on the aircraft, support can be provided for the reliability data, and whether the fault of the aircraft is caused by an equipment body or not is further determined from the angle of flight big data.
By adopting the troubleshooting method of the radio navigation system of the aircraft, provided by the embodiment of the invention, the operation data of the aircraft, namely the abnormal data of the aircraft can be obtained by acquiring the QAR data of the aircraft fleet when radio interference exists; then matching the fault data of GPWC systems of the aircraft to be troubleshooted with the abnormal data of the aircraft team, if the fault data can be successfully matched, the fault of the aircraft to be troubleshooted is caused by external radio interference, otherwise, the fault of the radio navigation system is indicated; by analyzing the flight data of the whole fleet, the faults of the aircraft to be eliminated can be automatically distinguished to be caused by the external environment or the faults of the aircraft equipment body, so that the complex isolation and elimination work of the aircraft under the condition of external interference is avoided, and the time cost and the maintenance cost are greatly reduced.
