Description
Technical Field
[0001] This invention relates to the field of low-altitude aircraft technology, specifically to an artificial intelligence-based operation and maintenance management system and method for low-altitude aircraft. Background Technology
[0002] Low-altitude aircraft refer to aircraft operating in airspace below 1000 meters vertically (extending to 3000 meters in some areas), encompassing both manned and unmanned types, primarily used for passenger transport, cargo transport, or special operations. Core types include electric vertical takeoff and landing (eVTOL) aircraft, drones, helicopters, and light fixed-wing aircraft. eVTOLs achieve vertical takeoff and landing through electric propulsion, suitable for urban air traffic; drones are characterized by their small size and low cost, widely used in aerial photography, agricultural plant protection, and other fields; helicopters possess hovering capabilities, adapting to complex terrain; light fixed-wing aircraft are fast and have long range, but require runways for takeoff and landing. Key technologies include navigation and obstacle avoidance (LiDAR, visual sensors), flight control systems (automated control and weather monitoring), and power systems (battery endurance optimization). Low-altitude aircraft play a vital role in agriculture, logistics, and rescue operations; for example, drones are used for precise pesticide spraying and rapid delivery of medical supplies.
[0003] Battery defects in low-altitude aircraft are a key factor affecting their safety and range. As the main power source, lithium batteries are prone to sudden drops in power, overheating and runaway, or even fire and explosion when operating under high load or extreme temperatures. Existing low-altitude aircraft operation and maintenance management systems lack effective management and monitoring of batteries, which may lead to loss of control or crash in the air due to battery failure.

It also prevents batteries from being exposed to high temperatures for extended periods, reducing heat damage and extending battery life. Through automated monitoring and fault diagnosis, it reduces the need for manual intervention, improving the efficiency of operation and maintenance management. Furthermore, in the event of a fault, it helps the system determine whether the aircraft is ready for a safe return, allowing for dynamic adjustments to flight plans and reducing the risk of drone crashes due to battery failures.

While sending the heat dissipation signal, the fault diagnosis module continuously monitors the battery heat dissipation efficiency index SRzs. If the battery heat dissipation efficiency index SRzs is still higher than the battery heat dissipation efficiency index SRzs within a preset time, a battery fault signal is sent to the planning and processing module.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0051] Please see Figure 1-2 The low-altitude aircraft operation and maintenance management system based on artificial intelligence includes a battery status monitoring module, a data analysis and management module, a fault diagnosis module, and a planning and processing module.

[0058] By using multi-dimensional data such as temperature, voltage, and current, a comprehensive evaluation of the battery can be conducted to achieve early detection of battery problems and preventive maintenance, reduce sudden failures and downtime, and provide a large data foundation for the analysis of battery heat dissipation efficiency index and health status index.
[0059] The data analysis and management module is used to calculate the battery heat dissipation efficiency index and health status index based on the monitoring data;
[0060] The formula for calculating the battery heat dissipation efficiency index SRzs is:
[0061]
[0062] In the calculation formula, SRzs represents the battery heat dissipation efficiency index, W i This represents the temperature monitoring data of the i-th battery. This represents the i-th ambient temperature data. This represents the sum of the differences between ambient temperature data and battery temperature monitoring data, starting from i=1 and ending at i=n, reflecting the battery's heat dissipation requirements.
[0063] W b The standard deviation between ambient temperature data and battery temperature monitoring data is represented by p, where p represents the battery's heat generation power. Represents the thermal resistance of the battery, indicating the resistance to temperature rise per unit power.
[0064] n represents the total number of data points, used in the denominator to standardize the impact of multi-point data.
[0065] The battery heat dissipation efficiency index SRzs can evaluate the heat dissipation efficiency of the battery in real time, determine whether the battery is within a safe temperature range, avoid the risk of thermal runaway or fire due to overheating of the battery, and prevent the battery performance from deteriorating in low temperature environments, which would affect the flight range and safety of the aircraft. The formula incorporates thermal resistance, which can directly reflect the effectiveness of the heat dissipation system.
[0066] The formula for calculating the health status index JKzs is:
[0067]
[0068] In the calculation formula, JKzs represents the health status index, and W i W represents the temperature monitoring data of the i-th battery. o Represents the standard battery temperature, W i -W o MaxW represents the difference between battery temperature monitoring data and standard data. c α1 represents the maximum permissible difference in battery temperature, and α1 represents the weight of the battery temperature data.

[0073] This reflects abnormal battery current. Excessive current may indicate battery overload or short circuit, while insufficient current may indicate degraded battery performance.
[0074] The health status index, which integrates temperature, voltage, and current deviations, reflects the overall health status of the battery, facilitating rapid assessment and decision-making. It provides real-time feedback on battery health, preventing flight accidents caused by battery failures and improving the safety and reliability of the aircraft.
[0075] The fault diagnosis module is used to diagnose faults in aircraft equipment based on battery heat dissipation efficiency index and health status index.
[0076] When the calculated value of the battery thermal efficiency index SRzs exceeds the battery thermal efficiency index threshold, it indicates that the current battery thermal performance is poor. A thermal signal is sent to optimize the thermal system. While sending the thermal signal, the fault diagnosis module continuously monitors the battery thermal efficiency index SRzs. If the battery thermal efficiency index SRzs is still higher than the battery thermal efficiency index SRzs within a preset time, a battery fault signal is sent to the planning and processing module.
[0077] By continuously monitoring the battery thermal efficiency index, the operating status of the cooling system can be detected in real time. When the battery thermal efficiency index exceeds the threshold, it indicates poor heat dissipation. The system will immediately trigger thermal optimization measures to prevent the battery from overheating due to poor heat dissipation, which could lead to serious problems such as thermal runaway, capacity decay, or fire and explosion. Timely heat dissipation prevents the battery from being in a high-temperature state for a long time, reduces heat damage to the battery, and extends battery life. At the same time, thermal optimization measures can eliminate temporary problems, improve the accuracy of system judgment, and reduce interference with flight plans.
[0078] When the health status index JKzs exceeds the health status index threshold, it indicates that the current battery health status is poor, and a poor battery health status signal is sent to the planning and processing module.
[0079] Real-time monitoring of health status indices enables automated monitoring and fault diagnosis, reducing the need for manual intervention and improving the efficiency of operation and maintenance management.
[0080] The planning and processing module is used to make emergency responses based on the fault diagnosis results;
[0081] Upon receiving either a battery fault signal or a poor battery health signal, the planning and processing module calculates the current battery return capability and takes emergency measures based on it. The formula for calculating the battery return capability FHnl is as follows:
[0082]
[0083] In the calculation formula, FHnl represents the battery's return capability, C represents the battery's nominal total capacity, JKzs represents the battery's state of health index, and X... dRepresents the current battery power consumption, SRzs represents the battery heat dissipation efficiency index, and X represents the current battery power consumption. j F represents the flight distance corresponding to the current battery consumption. j Represents the return distance;

[0086] In the calculation formula, FHnl represents the battery return capability, and X d X represents the current amount of electricity consumed by the battery. j This represents the flight distance corresponding to the current battery consumption. Average power consumption over distance.
[0087] Taking into account energy consumption, return distance, heat dissipation efficiency, and health status, the formula can comprehensively reflect the battery's return capability. It also reflects the negative impact of heat dissipation efficiency and health status on the return capability. When the system receives a battery fault signal or a poor health status signal, the formula can quickly calculate the battery's return capability, helping the system determine whether the aircraft has the conditions for a safe return, helping the system to dynamically adjust the flight plan, and reducing the problem of drone crashes that may be caused by battery failure.
[0088] When the battery return capability FHnl≥1, the planning and processing module sends a return signal to the aircraft; when the battery return capability FHnl<1, the planning and processing module sends a landing signal to the nearest landing site.
[0089] The specific methods of the aforementioned AI-based low-altitude aircraft operation and maintenance management system are as follows:
[0090] Step 1: Monitor the aircraft's status and collect monitoring data to form temperature monitoring dataset, voltage monitoring dataset, and current monitoring dataset, which are then recorded and saved.

[0092] Step 3: Judge the battery's heat dissipation effect based on the battery heat dissipation efficiency index. If the current battery heat dissipation effect is poor, send a heat dissipation signal to the heat dissipation system for heat dissipation optimization.
[0093] Step 4: After heat dissipation optimization, continuously monitor the battery heat dissipation efficiency index to determine if a malfunction has occurred; Step 5: Based on the health status index, determine whether the aircraft equipment has a poor battery health status.
[0094] Step 6: If either battery malfunction or poor battery health is detected, assess the current battery return capability.
[0095] Step 7: Take emergency measures based on the battery's return-to-home capability.
