Description

Technical Field

[0001] The present invention relates to the technical field of fault detection, and in particular, to a method and device for fault identification of an air traffic control omnidirectional beacon device. Background Art

[0002] When there is relative motion between a transmitting antenna and a receiving antenna, the frequency of the electromotive force induced by the receiving antenna is no longer equal to the frequency of the power supply of the transmitting antenna, and this phenomenon is called the Doppler effect. Based on the Doppler effect, omnidirectional beacon devices have emerged. Generally, omnidirectional beacon devices operate at relatively high frequencies and can provide a short-range radio navigation system for aircraft with respect to the magnetic azimuth of the ground station within a 360-degree range. The signals sent by a VOR transmitter are two: one is a reference signal with a fixed phase; the other signal's phase changes continuously with the circumferential angle around the beacon station, that is, the phases of the signals transmitted at each angle are different. The signal transmitted at 360 degrees (pointing to the magnetic north pole) is in phase with the reference signal (phase difference is 0), while the signal transmitted at 180 degrees (pointing to the magnetic south pole) has a phase difference of 180 degrees from the reference signal. The VOR receiver on the aircraft can calculate which angle signal from the beacon station it is located on based on the phase difference between the two received signals.

[0003] Currently, omnidirectional beacon devices are high-precision devices for positioning and navigation, and are widely applicable to fields such as aviation, unmanned aerial vehicles, and satellites. However, omnidirectional beacon devices may also malfunction during use, affecting aviation flights. Summary of the Invention

[0059] The embodiments of the present invention disclose a method, device, electronic device and storage medium for fault identification of an omnidirectional VHF beacon equipment. First, a corresponding and unique feedback identifier is assigned to different omnidirectional VHF beacon equipment. Through this feedback identifier, a unique omnidirectional VHF beacon equipment can be identified, and relevant information of the omnidirectional VHF beacon equipment is obtained. And the composition rule of the feedback character is set in advance. In the embodiment, the feedback character is used to determine whether the omnidirectional VHF beacon equipment is in a fault state, and the formed rule is convenient for automatically processing the feedback information. In the embodiment, the omnidirectional VHF beacon equipment is calibrated regularly to ensure that the equipment maintains the best working state, and whether there is a fault is monitored after the equipment is calibrated, which can avoid misjudgment. After it is determined that the omnidirectional VHF beacon equipment has been calibrated, the working state of the omnidirectional VHF beacon equipment is further evaluated in combination with the feedback character to determine whether the current omnidirectional VHF beacon equipment is in a normal or faulty state. Since the working state of the omnidirectional VHF beacon equipment is monitored regularly through the feedback character, the fault can be identified in time, and then the maintenance can be carried out in time and corresponding measures can be taken. The whole process is automated without manual intervention, which improves the efficiency and makes the operation more stable and reliable.

[0060] Embodiment 1

[0061] Please refer to Figure 1 , Figure 1It is a schematic flowchart of a fault identification method for an omnidirectional VHF radio range (VOR) equipment disclosed in an embodiment of the present invention. Among them, the execution subject of the method described in the embodiment of the present invention is an execution subject composed of software or / and hardware. This execution subject can receive relevant information through wired or / and wireless means and can send certain instructions. Of course, it can also have certain processing functions and storage functions. This execution subject can control multiple devices, such as remote physical servers or cloud servers and related software, or it can also be a local host or server and related software that performs relevant operations on devices placed somewhere. In some scenarios, it can also control multiple storage devices, and the storage devices can be placed in the same place or different places as the devices. As Figure 1 shown, the fault identification method for the omnidirectional VHF radio range equipment includes the following steps:

[0062] 101. Set the feedback identifier for each omnidirectional VHF radio range equipment in the target area and set the feedback character rule.

[0063] In the embodiment, the air traffic control area is divided for management. The target area is any selected area. In this target area, there are multiple omnidirectional VHF radio range equipment respectively set at different positions. Assigning a unique feedback identifier to each omnidirectional VHF radio range equipment helps to quickly identify the feedback of a specific equipment among numerous received signals.

[0064] Moreover, define a set of standard character formats or coding rules. When the omnidirectional VHF radio range equipment responds to the calibration instruction or works normally, it will generate and send feedback characters according to these rules, which helps to automatically and quickly process the feedback information.

[0065] Furthermore, the feedback character rule of the embodiment includes the feedback identifier + feedback character. Among them, the feedback characters generated at different time nodes correspond to different character strings. The character string can be a relatively long string of characters or a single character. Each character string corresponds to a feedback time. For example, the character A t1 , can represent the feedback character sent for the first time in the first time period after this calibration. In this example, a fixed detection period, such as 24 hours a day, is divided into multiple monitoring time periods. A corresponds to the first time period, B corresponds to the second time period, and so on. Secondly, t1 represents the first feedback character, t2 corresponds to the second feedback character, and so on. According to this type of feedback character rule, the length of the character can be minimized as much as possible, which helps to quickly transmit the feedback data, avoid occupying the transmission channel for a long time, and also helps to find out the meaning corresponding to the feedback character more efficiently.

[0066] In the embodiment, the feedback characters of the omnidirectional beacon device are detected at preset intervals, including: sending an inquiry instruction to the corresponding omnidirectional beacon device at preset intervals, where the inquiry instruction includes a character string of the feedback character; receiving the feedback character returned by the omnidirectional beacon device, classifying and archiving the feedback character according to the feedback identifier in the feedback character, and detecting whether there is a character string in the feedback character.

[0067] In this step, an inquiry instruction is sent to each confirmed normal omnidirectional beacon device at a preset time interval. Here, the inquiry instruction not only contains request information but also a specific character string, which is the key for subsequent comparison. The character string in the inquiry instruction can be a predefined, unique or regularly patterned character sequence, used to ensure that the received feedback character is directly related to the inquiry instruction, thereby improving the accuracy and efficiency of data processing.

[0068] 102. Send a calibration instruction to each omnidirectional beacon device in the target area at preset time intervals to calibrate each omnidirectional beacon device, and receive the calibration completion information feedback by the omnidirectional beacon device. The calibration completion information includes a completion signal and a feedback character.

[0069] By regularly sending calibration instructions to each omnidirectional beacon device in the target area, ensure that all devices remain in the optimal working state. The calibration process can include adjusting parameters such as amplitude, power, and phase to ensure the accuracy and stability of the signal. After sending the calibration instruction, receive the calibration completion information from the omnidirectional beacon device, including a completion signal and a feedback character. The completion signal indicates that the device has received and executed the calibration instruction, and the feedback character can be used for subsequent fault identification.

[0070] 103. When it is confirmed that the corresponding omnidirectional beacon device is normal based on the calibration completion information, the feedback characters of the omnidirectional beacon device are detected at preset intervals.

[0071] After confirming that the omnidirectional beacon device is normal, the system automatically detects the feedback characters of the device at preset intervals. This periodic detection helps to timely detect small changes in the device state, thereby preventing the occurrence of potential faults. By shortening the detection interval, the response speed to device state changes can be improved, ensuring the continuity and safety of the air traffic control system.

[0072] 104. Evaluate the working state of the omnidirectional beacon device according to the feedback character.

[0073] According to the received feedback character, combined with preset evaluation criteria or algorithms, evaluate the working state of the omnidirectional beacon device. If the feedback character indicates an abnormal device state (such as a weakened signal strength, a frequency offset exceeding the allowable range, etc.), corresponding measures can be taken in a timely manner.

[0074] In this step, the working state of the omnidirectional beacon device is evaluated according to the feedback character, including: obtaining the first timestamp of the received feedback character and the second timestamp of the sent inquiry instruction, calculating the time difference according to the first timestamp and the second timestamp, and judging whether the time difference is within the running time difference range; when the time difference is within the running time difference range, checking whether the string in the feedback character is consistent with the string in the inquiry instruction according to the feedback character rule, when the time difference is outside the running time difference range, defining the working state of the current omnidirectional beacon device as abnormal; when the string in the feedback character is consistent with the string in the inquiry instruction, defining the working state of the current omnidirectional beacon device as normal, otherwise defining the working state of the current omnidirectional beacon device as abnormal.

[0075] Record the first timestamp (denoted as T1) of the received feedback character and the second timestamp (denoted as T2) of the sent inquiry instruction. These two timestamps respectively represent the start and end moments of the device's response to the inquiry instruction. Calculate the time difference (ΔT = T1 - T2) according to T1 and T2. The time difference reflects the response time of the device from receiving the inquiry instruction to returning the feedback character. Then, judge whether this time difference ΔT is within the preset running time difference range. The running time difference range is comprehensively set according to factors such as the normal response speed of the device and network latency, and is used to judge whether the device's response is timely. If ΔT exceeds the running time difference range, it means that the response time of the device is too long or too short, and there may be problems such as communication failures, device failures, or network latency. At this time, define the working state of the current omnidirectional beacon device as abnormal.

[0076] After confirming that the time difference is within the operating time difference range, further check whether the string in the feedback character is the same as the string in the inquiry instruction. In the embodiment, weather reasons or equipment failures themselves may affect the transmission of signals. Poor signals may cause signal reception delays, etc. Therefore, in response to this situation, a time difference is set to address the problem of untimely transmission, and the first standby device, including signal amplifiers and other devices, is called. Specifically, when the operating state of the current omnidirectional beacon device is abnormal and the time difference is outside the operating time difference range, repeatedly send an inquiry instruction to the omnidirectional beacon device to receive the feedback characters repeatedly fed back from the omnidirectional beacon device. Based on the feedback characters of each feedback, count the proportion of the time difference outside the operating duration range in all the feedback characters. And when the proportion is greater than the set proportion value, start the first standby device; when the operating state of the current omnidirectional beacon device is abnormal and the time difference is within the operating time difference range, send a secondary inquiry instruction to the omnidirectional beacon device to receive the feedback characters fed back again from the omnidirectional beacon device. Compare whether the string in the feedback characters fed back again is the same as the string in the inquiry instruction. When they are inconsistent, define the omnidirectional beacon device as the current omnidirectional beacon device, and select at least one omnidirectional beacon device adjacent to the current omnidirectional beacon device as the confirmation omnidirectional beacon device; control the confirmation omnidirectional beacon device to send a waving signal to the current omnidirectional beacon device and receive the reply signal from the current omnidirectional beacon device; based on the reply signal, confirm whether the current omnidirectional beacon device has a fault. When it is confirmed that the current omnidirectional beacon device has a fault, start the second standby device of the current omnidirectional beacon device.

[0077] When it is detected that the working state of the current VOR device is abnormal and the time difference exceeds the operating time difference range, the system automatically sends a repeated inquiry instruction to the device. This is to verify whether the abnormality is caused by accidental factors (such as temporary network fluctuations) or whether there are persistent problems with the device itself. When the proportion of abnormal time differences statistically obtained is greater than the set proportion value (this proportion value can be adjusted according to the actual situation), it is considered that the device has persistent communication or response problems. Once it is confirmed that the device has persistent problems, the system immediately activates the first standby device to ensure the continuity and stability of the air traffic control system. When the time difference is within the operating time difference range, but the working state of the device is still determined to be abnormal (such as inconsistent feedback character content), a secondary inquiry instruction is sent to the device. This is to further confirm whether the device fails to correctly respond to the first inquiry due to some fault reasons (such as software errors, data processing delays, etc.). The system receives the re-feedback characters from the device and compares whether the strings in them are the same as the strings in the inquiry instruction. If they are not the same, it indicates that there are problems with the device in data processing or feedback generation. After confirming that there are problems with the current device, the system should select at least one VOR device adjacent to the current device as the confirmation VOR device. These devices will be used to further verify the state of the current device or assist in troubleshooting. The control confirmation VOR device is controlled to send a waving signal to the current device and wait for the received response signal. This step aims to check whether the current device can still respond to external signals, thereby further confirming its working state. If it is confirmed based on the response signal that the current device does have a fault, the system immediately activates the second standby device of the device.

[0078] Further, the embodiment may further include that when it is confirmed that there is a fault in the current VOR device, a self-check instruction is sent to the current VOR device, so that the current VOR device analyzes the components to be detected indicated in the self-check instruction after receiving the self-check instruction, and detects the components. In the self-check instruction, the components to be detected can be specified, such as indicators, transmitters, etc. When the VOR device receives the self-check instruction, it interacts with the components to be detected to confirm whether they are working properly, and records and feeds back the interaction results to the system.

[0079] The embodiment may further include that after an interval of a set duration, a repeated inquiry instruction is resent to the VOR device to receive the feedback characters repeatedly fed back by the VOR device, and based on the feedback characters of each feedback, the proportion of the time differences outside the operating duration range among all the feedback characters is statistically obtained, and when the proportion is less than the set proportion value, the VOR device is restarted. This step is usually applicable to weather conditions because the weather affects the VOR device in the short term. After the bad weather passes, the VOR device may spontaneously return to normal, and at this time, the VOR device is restarted.
