Technical Field

[0001] This invention relates to the field of aircraft technology, and in particular to an aircraft alarm presentation method, device, controller, aircraft, and medium. Background Technology

[0002] With the rapid development of urban air mobility, the demand for remote control of electric vertical takeoff and landing (eVTOL) aircraft is increasing. During missions, these aircraft face complex and ever-changing flight environments and diverse mission requirements, making alarm presentation particularly important.

[0003] However, in existing technologies, alarm information overload occurs when a large number of alarms are presented simultaneously, placing an excessive cognitive burden on operators. Furthermore, due to the limited presentation methods, it is often difficult to quickly and accurately identify critical alarms when faced with such a large volume of alarm information. This fails to meet the information transmission needs in complex scenarios, affecting information comprehension and response accuracy, and reducing alarm information processing efficiency. This not only impacts the safe operation of the aircraft but may also seriously hinder mission execution. Therefore, how to achieve different presentations of alarm information and ensure improved alarm information processing efficiency is a pressing technical problem that needs to be solved. Summary of the Invention

Therefore, phrases appearing in different parts of this specification as referring to one embodiment, some embodiments, some other embodiments, and others do not necessarily refer to the same embodiment, but rather mean one or more, but not all, embodiments, unless otherwise specifically emphasized. The terms include, comprise, have, and variations thereof mean including but not limited to, unless otherwise specifically emphasized.

[0019] It should be understood that the sequence number of each step in the following embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0020] To illustrate the technical solution of the present invention, specific embodiments are described below.

[0021] See Figure 1 This is a flowchart illustrating an aircraft alarm presentation method according to an embodiment of the present invention, as shown below. Figure 1 As shown, the aircraft alarm presentation method can be implemented through the following steps.

[0022] S101: Acquire multi-source alarm information and flight status data of the aircraft, and preprocess the multi-source alarm information to obtain target alarm information.

[0023] In one implementation, 5G NR (Fifth Generation Mobile Communication Network) technology is used to establish a low-latency data channel between the 5G base station and the eVTOL aircraft, enabling real-time reception of alarm information. This information is acquired through various sensors onboard the aircraft, including but not limited to radar, infrared, and acoustic sensors. These sensors collect real-time information about the aircraft's surrounding environment and its own operational status. Multiple data interfaces within the alarm drive system of the eVTOL aircraft are used to obtain multi-source alarm information from various subsystems of the alarm drive system, such as the power system, flight control system, and flight management system. Each type of alarm information typically corresponds to a specific aspect of the aircraft's operation, and its importance and urgency may vary depending on the system type. This multi-source alarm information covers various types of alarms, such as engine failure alarms, navigation system anomaly alarms, and hazardous weather condition alarms. These alarms may originate from the aircraft's own monitoring system or from ground control centers or other external monitoring equipment. Flight status data includes key parameters such as the aircraft's speed, altitude, heading, and attitude, which are crucial for accurately determining the aircraft's current status.

[0024] Furthermore, single alarms are often difficult to reproduce. Therefore, for certain subsystems of the alarm drive system in an eVTOL aircraft, when multiple repeated alarms occur consecutively, an alarm can be identified and collected as a single alarm message. For example, for the first subsystem of the alarm drive system in an eVTOL aircraft, when the number of repeated alarms from the first subsystem reaches a preset number (e.g., 5 times) within a preset time period (e.g., 25 minutes), an alarm message for the first subsystem can be generated and used as the first alarm message among the aforementioned multiple alarm messages. Similarly, for the second subsystem and others in the eVTOL aircraft, a similar method can be used to determine the second alarm message for the second subsystem, and so on, until the multi-source alarm information of each subsystem in the alarm drive system of the eVTOL aircraft is obtained.

[0025] Because these multi-source alarm messages may have different data formats, transmission protocols, or semantic structures, they need to be preprocessed—that is, standardized—to unify data formats, transmission protocols, and semantic structures, thereby obtaining the target alarm message for subsequent unified analysis and processing. A dedicated data conversion module can be designed to convert alarm messages from different sources and in different formats into a unified standard format. After the data conversion module is designed, an efficient and stable database system needs to be built to store these standardized target alarm messages. This database system should have powerful data storage capabilities, fast data retrieval capabilities, and reliable data security mechanisms to ensure that the required alarm information can be quickly and accurately obtained when needed, providing strong data support for the safe operation of the aircraft. For example, common data exchange formats such as JSON and XML can be used, while defining unified semantic rules to ensure accurate interpretation of different types of alarm messages. Through the above approach, the differences between multi-source alarm messages can be eliminated, resulting in target alarm messages with clear structure and explicit semantics, making subsequent data processing and analysis more efficient and accurate, and ensuring the safe operation of the aircraft.

[0026] S102: Based on the preset priority rules and the flight status data, determine the priority corresponding to the target alarm information.

[0027] In one implementation, the alarm-driven system in the eVTOL aircraft first loads a pre-defined priority rule base. This rule base is derived from extensive flight data analysis and expert experience, covering various possible flight scenarios and alarm types. Simultaneously, the system acquires flight status data in real time, including key parameters such as altitude, speed, heading, and weather conditions. Next, the system uses advanced algorithms to match and calculate this flight status data against the pre-defined priority rules, thereby accurately determining the priority of each target alarm message. Priorities are typically divided into high, medium, and low levels to allow for targeted processing and presentation. For example, if the alarm type is "system failure" and the flight altitude is below a safety threshold, its priority is set to high. It should be noted that the pre-defined priority rules can be formulated based on the safety criticality of different operating states of the aircraft; this application does not impose any limitations on this. For instance, during takeoff and landing, alarm messages related to altitude and speed have higher priority than those during other phases. Another approach is to pre-define a static priority list, associating each alarm type with a fixed priority level. When a target alarm is received, the list is queried directly to obtain its priority.

[0028] Furthermore, different types of systems have different priorities for target alarm information, and / or, even systems of the same type have different priorities for target alarm information. In other words, alarm information generated by different types of systems inherently has different priorities. For example, alarms generated by systems directly related to flight safety (such as flight control systems and power systems) typically have higher priority than alarms generated by systems related to auxiliary functions (such as cabin service systems and infotainment systems). This difference is determined by the varying degrees of criticality and potential risks of different systems in the overall operation of the aircraft. In practical applications, a basic alarm priority weight or range can be assigned to different types of systems during the system design phase or through preset configuration for reference in subsequent priority determination. Moreover, even within the same type of system, such as multiple power systems or redundant navigation systems on an aircraft, alarm information generated by different individual systems may have different priorities. This may be because these systems play slightly different roles in the aircraft architecture, or because the importance of a particular system may temporarily increase during a specific flight phase. For example, in twin-engine aircraft, warnings from the left engine and the right engine may be assigned different initial priorities in certain situations, or there may be differences in warning priorities between the primary and backup systems. This nuanced distinction helps to more accurately assess the urgency of warnings, ensuring that critical warnings are prioritized. This avoids the priority assessment bias caused by treating all target warning information indiscriminately, ensuring that critical warnings are accurately identified and assigned appropriate priorities. This provides a more reliable basis for subsequent warning presentation, improving the effectiveness of warning handling and the level of flight safety assurance.

[0029] In this embodiment, by comprehensively analyzing these preset priority rules and real-time acquired flight status data, the system can accurately assign corresponding priorities to target alarm information. This allows alarm information to be presented and processed according to priority order, ensuring that flight personnel can prioritize and handle alarm information that has the greatest impact on flight safety. Furthermore, it ensures that critical alarm information can be processed promptly and effectively in complex flight environments. This dynamic adjustment mechanism not only improves flight safety but also enhances the system's flexibility and adaptability. For example, if severe weather conditions are encountered during flight, the system can quickly identify and prioritize weather-related alarm information so that pilots can take immediate action.

[0030] S103: Determine different presentation methods of the target alarm information according to the priority corresponding to the target alarm information.

[0031] In one implementation, the presentation of target alarm information is flexibly adjusted based on its priority, allowing for different presentations of the alarm information and ensuring that pilots receive the most critical information immediately. For example, a single presentation method can be preset for each priority level. Different colors, sounds, icons, or vibration modes can be used to present the target alarm information according to its priority. High-priority alarms can be displayed in a striking red with a rapid alarm sound to draw the pilots' immediate attention; medium-priority alarms can be displayed in yellow with a gentler tone; and low-priority alarms can be displayed in green with only slight vibration or text prompts. By assigning different display priorities and effects to different types of alarm information, pilots can quickly identify and differentiate alarms of varying priorities, enabling more accurate and timely responses and ensuring the safe operation of aircraft in complex mission environments.

[0032] In summary, this invention provides an aircraft alarm presentation method, apparatus, controller, aircraft, and medium. By acquiring multi-source alarm information and flight status data from the aircraft, and preprocessing the multi-source alarm information to obtain target alarm information, the priority of the target alarm information is determined based on preset priority rules and flight status data. Different presentation methods for the target alarm information are then determined according to its priority. Therefore, this application ensures that alarm information of different urgency levels is perceived by operators in the most appropriate way by determining different presentation methods based on the priority of the target alarm information, thereby achieving different presentations of alarm information, improving alarm information processing efficiency, and effectively enhancing flight safety and operational efficiency.

[0033] In one embodiment, specifically in step S101, which involves preprocessing the multi-source alarm information to obtain the target alarm information, the following steps are included: The multi-source alarm information is cleaned and standardized to obtain the processed multi-source alarm information; The processed multi-source alarm information is classified to obtain the target alarm information.

[0034] Specifically, by cleaning and standardizing multi-source alarm information, processed multi-source alarm information is obtained. Data cleaning and standardization refer to the process of identifying, correcting, or removing erroneous, inaccurate, incomplete, or irrelevant parts of the multi-source alarm information. This can include removing duplicate data, filling in missing values ​​(e.g., through interpolation or default values), correcting format errors (e.g., inconsistent date formats), and identifying and handling outliers (e.g., sensor readings outside a reasonable range). Standardization refers to unifying multi-source alarm information from different sources and in different formats into a preset, consistent data format and representation. For example, unifying physical quantities in different units (such as temperature and pressure) into standard units, and mapping alarm events with different descriptions (such as "motor overheating" and "motor high temperature") to a unified alarm type identifier. The processed multi-source alarm information is then classified to obtain target alarm information. Classification refers to assigning the cleaned and standardized alarm information to specific alarm categories according to preset rules or models. For example, alarm information can be categorized into "power system alarms," ​​"flight control system alarms," ​​and "flight management system alarms." Classification processing can be based on the text content of the alarm information (keyword matching, natural language processing), the source system identifier, and the range of alarm parameters. This approach eliminates noise and inconsistencies in the original multi-source alarm information, ensuring data quality and consistency for subsequent processing. This provides structured input for subsequent prioritization, allowing the system to adopt different processing strategies for different types of alarms, improving the efficiency and accuracy of alarm processing. Ultimately, this helps the aircraft understand alarm information more quickly and accurately, take timely countermeasures, and ensure flight safety.

[0035] In one embodiment, specifically in step S102, the priority rules include type allocation sub-rules, urgency adjustment sub-rules, frequency correction sub-rules, and suppression sub-rules. That is, determining the priority corresponding to the target alarm information based on preset priority rules and flight status data includes the following steps: Based on the type allocation sub-rules, different basic priority scores are assigned to each target alarm message according to the alarm type to obtain the first priority ranking, wherein the alarm types include warning alarms, alert alarms and advisory alarms; Based on the aforementioned urgency adjustment sub-rule, the priority of each target alarm message is adjusted according to the importance of the target alarm message and the flight status data to obtain a second priority ranking; Based on the frequency correction sub-rule, the priority of each target alarm message is adjusted according to the historical alarm occurrence frequency to obtain a third priority ranking. The first priority sort, the second priority sort, and the third priority sort are weighted and summed according to preset weights to obtain the initial priority corresponding to the target alarm information; Based on the suppression sub-rule, each target alarm message is subjected to information suppression processing by the relevance of the target alarm message and the initial priority corresponding to the target alarm message, so as to obtain the priority corresponding to the target alarm message.

[0036] Specifically, firstly, based on the type allocation sub-rules, each target alarm message is meticulously identified according to its type. These alarm types are clearly divided into three main categories: warning alarms, alert alarms, and advisory alarms, each corresponding to a different basic priority score. The system automatically compares the characteristics of the target alarm message with the definitions in the rule base to accurately determine its type and assign a corresponding basic priority score to obtain the first priority ranking. This process ensures the objectivity and accuracy of the first priority ranking. Among them, warning alarms typically indicate events that pose a direct threat to flight safety and are assigned the highest basic priority score; alert alarms indicate potential risks or events requiring attention and are assigned a medium basic priority score; while advisory alarms provide informational alerts and are assigned a lower basic priority score. This classification and allocation ensures that alarms possess distinguishability based on their inherent properties from the initial stage. Then, based on the urgency adjustment sub-rules, the priority of each target alarm message is adjusted by comprehensively considering the importance of the event corresponding to the target alarm message and the current flight status data of the aircraft, thus obtaining a second priority ranking. The importance includes factors such as the severity of the event's impact on flight safety and the criticality of the system involved; the flight status data includes flight speed, altitude, attitude, and navigation information. This adjustment process fully considers real-time changes during flight, making the alarm priority more closely match the actual flight scenario and providing pilots with more accurate and timely warnings.

[0037] Furthermore, based on frequency correction sub-rules, the priority of each target alarm message is adjusted according to the historical alarm occurrence frequency, resulting in a third priority ranking. The statistics on historical alarm occurrence frequency cover multiple dimensions, including different flight phases, different flight environments, and different aircraft types. Alarm messages that frequently occur in specific flight phases or environments will have their priority appropriately lowered, as frequent occurrence may indicate that the alarm is not an urgent or critical issue, or that the pilot has already developed some experience and ability to handle it. Conversely, alarm messages that rarely occur but could have serious consequences when they do, will have their priority increased to ensure that the pilot can quickly pay attention and take effective measures. For example, alarms that occur frequently in a short period of time may indicate a deep system fault, and their priority should be increased; while alarms that persist for a long time without deterioration and are known to the aircraft can have their priority appropriately lowered to avoid information fatigue. Through this frequency-based correction, the third priority ranking can more comprehensively reflect the actual importance and urgency of alarm messages. The first, second, and third priority rankings are then weighted and summed according to preset weights to obtain the initial priority corresponding to the target alarm information. In the weighted summation process, the preset weights fully consider the importance of different priorities in the overall assessment. Through this comprehensive weighting method, the final initial priority corresponding to the target alarm information can comprehensively and objectively reflect the actual importance and urgency of the alarm information, providing strong support for pilot decision-making.

[0038] Finally, when performing information suppression, it is first necessary to clarify the correlation between target alarm messages. This correlation can be determined by analyzing factors such as the source, nature, and scope of impact of the alarm messages. For highly correlated target alarm messages, if their initial priorities differ, appropriate adjustments need to be made based on the actual situation to avoid important information being overlooked due to improper priority settings. Simultaneously, combining the initial priorities of the target alarm messages, a specific suppression algorithm is used to comprehensively evaluate each target alarm message, ultimately determining the priority of each target alarm message within the overall alarm system. It should be noted that manual suppression of alarm messages can also be achieved through the manual intervention interface module in the alarm-driven system of the eVTOL aircraft, i.e., through selective selection or batch selection functions. For example, when a main system failure triggers multiple cascading alarms, the suppression sub-rules can identify these correlations, presenting only the most critical alarms or reducing the presentation intensity of secondary alarms, thereby preventing the aircraft from being overwhelmed by excessive information. The above scheme significantly improves the accuracy and rationality of alarm priority classification, avoids misjudgment or omission that may be caused by a single factor, effectively reduces the interference of redundant alarms on the aircraft, and enables the aircraft to identify the most critical and urgent alarms more quickly and accurately, thereby improving the response efficiency and decision-making quality to abnormal situations of the aircraft and ensuring flight safety.

[0039] In one embodiment, specifically in step S103, which involves determining different presentation methods of the target alarm information based on its priority, the following steps are included: If the priority corresponding to the target alarm information is the first target alarm priority, then the presentation mode of the target alarm information is determined to be the first information presentation mode, wherein the first information presentation mode is a first auditory prompt and a first visual warning. The first auditory prompt includes a voice prompt that is played in a loop at a first preset time interval and an alarm sound with a first audio frequency. The first visual warning includes alarm text information and a warning sign that flashes at a first flashing frequency. If the priority corresponding to the target alarm information is the second target alarm priority, then the presentation mode of the target alarm information is determined to be the second information presentation mode, wherein the second information presentation mode is a second auditory prompt and a second visual warning. The second auditory prompt includes a voice prompt that is played in a loop at a second frequency and an alarm sound with a second audio frequency. The second visual warning includes alarm text information and a warning sign that flashes at a second flashing frequency. If the priority corresponding to the target alarm information is the third target alarm priority, then the presentation method of the target alarm information is determined to be the third information presentation method, wherein the third information presentation method is a third auditory prompt and a third visual warning, the third auditory prompt is a single tone prompt, and the third visual warning is only an alarm information text display, wherein the priorities of the first target alarm priority, the second target alarm priority, and the third target alarm priority decrease in sequence.

[0040] In one implementation, when a target alarm message is determined to be the first target alarm priority, its presentation method is set to a first information presentation method. This first information presentation method includes a combination of a first auditory prompt and a first visual warning. The first auditory prompt includes a voice prompt that loops at a first preset time interval and an alarm tone with a first audio frequency. The first visual warning includes alarm text information and a warning sign flashing at a first flashing frequency. In actual operation, this presentation method can quickly attract the pilot's attention. The voice prompt that loops at the first preset time interval serves as a high-frequency repetitive voice prompt, such as a rapid and continuous "warning, warning" sound, combined with an alarm tone with a first audio frequency (high-frequency tone), such as a sharp buzzing sound, providing the pilot with a strong warning signal from an auditory perspective. Meanwhile, visually, the alarm text is clearly displayed on the aircraft's display interface in a striking color, such as red, and is accompanied by a warning indicator that flashes at the first flashing frequency (high-frequency flashing), such as a flashing red triangle or circle icon. This first flashing frequency (high-frequency flashing) can further enhance the visual impact and ensure that the pilot notices the first target alarm priority information at the first time, so as to take appropriate countermeasures in a timely manner and ensure flight safety.

[0041] When a target alarm message is determined to be the second target alarm priority, its presentation method is set to the second information presentation method. This second information presentation method includes a combination of second auditory cues and second visual warnings. The second auditory cues include a voice prompt that loops at a second frequency and an alarm tone with a second audio frequency. The second visual warning includes alarm text information and a warning symbol flashing at a second flashing frequency. In actual operation, the voice prompt that loops at the second frequency is used as a low-frequency repetitive voice prompt, such as a slightly spaced and repeated "Attention, attention" sound, paired with the alarm tone with a second audio frequency (mid-frequency tone), to convey a relatively clear warning to the pilot audibly. The alarm tone with a second audio frequency (mid-frequency tone) is not as sharp and piercing as a high-frequency tone, but it still has a certain alerting effect. Visually, the alarm text is also presented clearly on the aircraft's display interface in a relatively conspicuous color, such as orange, accompanied by a warning symbol flashing at a second flashing frequency (low-frequency flashing), like a slowly flashing orange square icon. Although this second flashing frequency (low-frequency flashing) is not as intense as the first flashing frequency (high-frequency flashing), it can still continuously attract the pilot's attention, allowing the pilot to notice the priority information of the second target warning in a timely manner, and thus take appropriate action to maintain the stability and safety of the flight process.

[0042] When a target alarm message is determined to be a third-priority target alarm, its presentation method is set to a third-information presentation method. This method combines a third-auditory cue and a third-visual warning. The third-auditory cue is a single-tone alert, serving only as a one-time information arrival signal. The third-visual warning is simply a text display of the alarm message. The aircraft can view the detailed alarm content as needed without requiring additional mandatory alerts. The single-tone cue is typically a short, clear, and non-harsh sound, such as a soft "ding." For the third-visual warning, the alarm message text is displayed in a relatively inconspicuous color, such as light gray or light blue, in a specific area of ​​the aircraft's display interface. This specific area usually does not occupy the main part of the display interface. The aircraft can view the detailed alarm content itself when needed. This method avoids excessive visual interference while ensuring that necessary information is provided when required. Furthermore, the priority of the first-target alarm, second-target alarm, and third-target alarm decreases sequentially. Through the above-mentioned scheme, this application can combine alarm priority with specific and differentiated auditory and visual presentation methods, thereby ensuring that alarm information of different urgency levels is perceived by operators in the most appropriate way, improving the recognition efficiency and response speed of alarm information, optimizing the human-computer interaction experience, and thus effectively improving flight safety and operational efficiency.

[0043] In one embodiment, after step S103, that is, after determining the different presentation methods of the target alarm information, the following steps are included: Obtain the processing status and alarm details of each target alarm message, wherein the processing status is used to indicate whether the target alarm message has been processed, and the alarm details include alarm time, alarm content, and alarm reason; For any unprocessed target alarm information, a processing reminder message corresponding to the target alarm information is sent, and corresponding alarm processing measures are taken based on the alarm details. For the target alarm information that has been processed, determine whether the system indicator value of the business system corresponding to the target alarm information has returned to normal. If it has not returned to normal, modify the processing status of the target alarm information.

[0044] In one implementation, a detailed alarm information viewing interface is provided through the manual intervention interface module of the alarm-driven system in the eVTOL aircraft. This allows for the acquisition of the processing status and alarm details for each target alarm. The processing status indicates whether the target alarm has been processed, while the alarm details include the alarm time, alarm content, and alarm reason. For unprocessed target alarms, the alarm-driven system sends a corresponding processing reminder to the aircraft and takes appropriate alarm processing measures based on the alarm details. When the system detects that a target alarm has been in an "unprocessed" state for an extended period, it proactively sends a processing reminder to the aircraft. This reminder can take various forms, such as re-displaying the alarm on the cockpit display screen as a highlight, flashing icon, or pop-up window, or issuing a repeated voice prompt via a speech synthesis system to ensure the aircraft notices the unprocessed alarm. The frequency and intensity of the reminder can be dynamically adjusted according to the alarm priority. Simultaneously, based on the alarm details, the alarm-driven system can provide the aircraft with targeted processing suggestions or operational guidance. For example, for an alarm of "low engine oil pressure", the system can display a corresponding checklist, troubleshooting steps or emergency operating procedures (SOPs), and can even link with the flight management system to automatically adjust relevant parameters or isolate the faulty unit to help the aircraft respond to the alarm quickly and accurately.

[0045] Furthermore, for processed target alarm information, the system will determine whether the system indicator values ​​of the corresponding business system have returned to normal. If not, the processing status of the target alarm information will be modified. After the aircraft performs initial processing of the alarm, the system will continuously monitor the key operating indicators of the business systems related to the alarm. For example, for an alarm of "low engine oil pressure," the system will continuously monitor the engine oil pressure sensor data. If the oil pressure value returns to the normal range and remains stable after processing, the alarm is considered to have been effectively resolved. This process may involve comparison with preset thresholds, trend analysis, or comparison with other normal system data. If the system detects that the indicator values ​​of the relevant business system have not returned to normal after the aircraft's processing, it indicates that the alarm has not been truly resolved or has not been thoroughly processed. At this time, the alarm-driven system will change the processing status of the target alarm information from "processed" back to "unprocessed" or "processing failed," and may trigger the processing reminder mechanism again to prompt the aircraft to reassess and take further measures to ensure that the problem is thoroughly resolved. The above technical solutions can significantly improve the efficiency and accuracy of aircraft alarm processing, allowing the aircraft to fully understand the details of alarms through the manual intervention interface module, including both processed and unprocessed alarms, thereby making more reasonable response measures, effectively avoiding safety hazards caused by human negligence, and improving the safety and reliability of the aircraft.
