Description

Technical Field

[0001] The present invention relates to the technical field of low-altitude economic processing, and specifically to a system that integrates multiple devices to ensure low-altitude flight safety and enhance flight experience. Background Art

[0002] With the development of the low-altitude economy, application scenarios such as drone delivery, low-altitude tourism, and emergency rescue are constantly emerging. However, existing low-altitude equipment has the following shortcomings in terms of functional integration, safety, positioning accuracy, and intelligent control: (I) CPU (central processing unit): Currently, the CPU processing capacity of low-altitude equipment is limited, which makes it difficult to meet the needs of complex flight control algorithms, data processing, and multi-device collaboration. For example, when processing flight attitude data, satellite positioning data, and microwave signal reception and processing at the same time, data congestion and processing delays are likely to occur.

[0003] (II) In terms of microwave signal devices, traditional microwave signal devices have poor signal transmission stability and anti-interference capabilities in low-altitude environments. In complex environments such as cities, obstacles such as tall buildings can easily interfere with the transmission of microwave signals, affecting communication between devices and detection of the surrounding environment.

[0004] (III) With regard to flashing devices, existing flashing devices have a single function and are merely used as a simple sign, with poor visibility and warning effects under different lighting conditions.

[0005] (iv) In terms of parachutes, the deployment mechanism of parachutes is not intelligent enough and is often triggered based on simple altitude or fault conditions. It cannot comprehensively consider factors such as the flight attitude, speed and surrounding environment of the equipment, resulting in its inability to function effectively in some emergency situations.

[0006] (V) Regarding gyro balancers, the accuracy of existing gyro balancers will gradually decrease during long-term flight or when subject to external interference, affecting the flight stability of low-altitude equipment.

[0007] (VI) In terms of automatic alarm devices, the triggering conditions and alarm methods of automatic alarm devices are relatively simple and cannot transmit comprehensive fault information or dangerous conditions to operators or monitoring centers in a timely and accurate manner.

[0008] (VII) Regarding satellite positioning systems, in some complex low-altitude environments, such as mountainous areas or cities with tall buildings, the positioning accuracy of satellite positioning systems will be affected, resulting in deviations in the flight path of low-altitude equipment.

[0009] (8) In terms of optical radar, the detection range and resolution of optical radar in low-altitude environments need to be improved, and its performance is unstable in complex environments such as strong light and smoke.

[0010] In summary, there is currently no system that effectively integrates CPU (central processing unit), microwave annunciator, flash device, parachute, gyroscope balancing device, battery, automatic alarm device, satellite positioning device, optical radar and health monitoring equipment to meet the needs of low-altitude economic development.

The gyroscope balance device 7 is installed near the center of gravity of the low-altitude flight device to accurately measure the flight attitude. After the installation is completed, a calibration operation is performed so that the roll angle, pitch angle and yaw angle of the flight equipment can be accurately detected at low altitude. The battery 2 is installed in the battery compartment of the low-altitude flight equipment. The automatic alarm device 8 is installed in the control cabin of the low-altitude flight equipment and is connected to the high-performance multi-core CPU 3 and the microwave signal device 4, and the alarm triggering conditions and the target address for sending the alarm signal (such as the communication address of the ground control center, the pilot's mobile device number, etc.) are set. The satellite positioning device 9 is installed on the top of the low-altitude flight equipment or other locations that can well receive satellite signals. The satellite positioning device 9 is initialized so that it can quickly obtain satellite signals and accurately calculate the location information of the flight equipment. The optical radar 10 is installed at the front end or bottom of the low-altitude flight equipment to perceive the environment in front of and below the flight, and the optical radar is calibrated to set its scanning range, resolution and other parameters. The health monitoring device 11 is installed near the seat of the flight personnel or directly worn on the flight personnel (such as a wearable health monitoring device), and the health monitoring device 11 is connected to the microwave signal device 4 to ensure that the collected health data can be transmitted in time.

[0030] Preferably, the automatic alarm device 8 can send alarm signals in a variety of ways, such as sending a radio alarm signal to the ground control center, sending a notification to the pilot's mobile device, etc., and the alarm signal contains detailed abnormal information, such as the type of fault, the location of occurrence, and the degree of urgency. For example, if the engine of the flight equipment fails, the alarm signal will indicate the specific fault code of the engine so that ground maintenance personnel can quickly prepare maintenance tools and parts.

[0031] Preferably, during the flight, the optical radar 10 can detect obstacles in advance and transmit this information to the high-performance multi-core CPU 3. The high-performance multi-core CPU 3 adjusts the flight path according to this information to avoid collision accidents.

[0032] Preferably, the parachute triggering device 6 can accurately determine when and how to deploy the parachute based on the flight attitude data provided by the gyroscope balancing device 7, the altitude data of the satellite positioning system, the device speed calculated by the CPU, and the surrounding environment data factors.

[0033] Preferably, the gyro balancing device 7 can detect the change of the yaw angle of the flying device in time when encountering a crosswind, and adjust the rudder through the instructions of the high-performance multi-core CPU 3 to keep the flying device in the correct flight direction.

[0034] In this embodiment, the CPU is improved by using a high-performance multi-core CPU architecture, which is optimized specifically for low-altitude economic applications. Through parallel processing algorithms, it is possible to simultaneously and efficiently process attitude data from the gyro balancer, position data from the satellite positioning system, communication data from the microwave signaler, etc., and an adaptive CPU frequency adjustment mechanism is used to automatically adjust the CPU frequency according to the load of the device to balance performance and power consumption. For example, when the device is in a stable flight state and the data processing demand is small, the CPU frequency is reduced to save battery power; when performing complex flight missions or responding to emergencies, the CPU frequency is increased to ensure rapid data processing; Optimization of microwave signal generator 4 Adopt new microwave frequency bands and modulation technologies to improve the stability and anti-interference ability of signal transmission. By integrating adaptive filtering algorithms in microwave signal transmitters, interference signals from the surrounding environment can be identified and filtered out in real time. Multi-antenna microwave signal receiving and transmitting systems are adopted to enhance the signal coverage and receiving sensitivity through the coordinated work of multiple antennas. For example, in an urban environment, even if some antennas are blocked by buildings, other antennas can still ensure the normal transmission of signals. The flash device 5 is designed as an intelligent flash device, and its flash frequency, intensity and color can be automatically adjusted according to the ambient light conditions. In a strong light environment, the flash intensity is increased and the flash color is changed to enhance visibility; at night or in a low light environment, the flash intensity is reduced to avoid excessive interference with the surrounding environment. The flash device 5 is connected to the automatic alarm device 8. When the automatic alarm device is triggered, the flash device warns with a specific flashing mode, such as fast flashing red light, so that the operator or other relevant personnel can quickly identify the dangerous state of the equipment.

[0035] Improvement of the parachute trigger device 6, a parachute intelligent deployment system based on multi-sensor fusion. The system comprehensively considers factors such as flight attitude data provided by the gyro balancer, altitude data from the satellite positioning system, device speed and surrounding environment data calculated by the CPU, and accurately determines when and how to deploy the parachute. The later structure of the parachute adopts a new type of lightweight and high-strength material, which reduces the weight of the parachute while ensuring the reliability of the parachute, reducing the impact on the overall performance of the equipment; The gyro balance device 7 is upgraded with a high-precision gyro sensor combined with an advanced calibration algorithm. The algorithm regularly calibrates the gyro balancer using the precise position data of the satellite positioning system to ensure its accuracy during long-term flight. At the same time, a redundant backup system for the gyro balancer is designed. When the main gyro balancer fails, the backup system can immediately take over the work to ensure the flight stability of the low-altitude equipment; Battery 2 uses high energy density batteries, special electrode materials and electrolyte formulas to improve the battery's energy storage capacity. At the same time, the battery's charging speed has been significantly improved. It uses fast charging technology to fully charge the battery in a short time. It has its own battery management system that can automatically adjust the battery's working state according to the ambient temperature. In low temperature environments, the heating device is activated to maintain the battery's performance; in high temperature environments, the heat dissipation device is used to prevent the battery from overheating; The triggering conditions of the automatic alarm device 8 are more diversified. In addition to the traditional hardware failure trigger, the alarm can also be triggered according to abnormal data processed by the CPU, the positioning deviation of the satellite positioning system exceeds the threshold, the microwave signal is interrupted, etc.; the alarm method adopts a combination of various forms, including sound alarm, sending alarm information to the control center through a microwave signal device, and controlling the flash device to flash an alarm, etc., to ensure that the alarm information can be conveyed in a timely and accurate manner.

[0036] Satellite positioning device 9 is enhanced, using the integrated positioning technology of satellite positioning system, optical radar and microwave signal device. Optical radar and microwave signal device can supplement the satellite positioning system. When the satellite signal is blocked or interfered, the optical radar's short-range high-precision positioning and the microwave signal device's relative positioning capability are used to improve the overall positioning accuracy. A satellite positioning signal enhancement algorithm is developed to improve the positioning stability of the satellite positioning system in complex low-altitude environments by optimizing the processing of multiple satellite signals. Optimize the optical system and signal processing algorithm of the optical radar 10 to improve the detection range and resolution of the optical radar. By adopting a new laser emission source and a highly sensitive photoelectric detector, as well as advanced signal processing algorithms, it is possible to more accurately detect obstacles and terrain information in low-altitude environments. At the same time, the adaptive working mode of the optical radar 10 is set to reduce the laser emission power in a strong light environment to avoid interference; in low-visibility environments such as smoke, the laser emission frequency and signal processing gain are increased to enhance detection capabilities.

[0037] The software algorithms that need to be explained are as follows: The adaptive frequency adjustment algorithm in the CPU adjusts the CPU frequency according to preset rules by monitoring the load of the device in real time, such as data flow, task queue, etc. The load monitoring program runs regularly to ensure the timeliness of frequency adjustment.

[0038] The adaptive filtering algorithm in the microwave signal generator uses digital signal processing technology to analyze the received microwave signal in real time, identify the characteristics of the interference signal, and remove it through the filtering algorithm. The parameters of the filtering algorithm can be adaptively adjusted according to changes in the environment.

[0039] The intelligent control algorithm of the flash device determines the current lighting environment based on the data from the ambient light sensor, and then adjusts the flash frequency, intensity and color according to preset rules. The data collection frequency of the ambient light sensor is set according to the flight speed of the device and the possibility of environmental changes.

[0040] The intelligent deployment algorithm of the parachute comprehensively analyzes multi-source data such as the gyro balancer, satellite positioning system, speed and environmental data calculated by the CPU, etc. The data fusion technology is used to fuse these data, and then decide whether to deploy the parachute and how to deploy it according to the preset danger condition judgment criteria.

[0041] The calibration algorithm of the gyro balancer uses the precise position data of the satellite positioning system to calculate the deviation of the gyro balancer by comparing the theoretical position of the device with the actual position, and calibrate it. The calibration operation is performed regularly, and the calibration cycle is adjusted according to the flight time and environmental conditions of the device.

[0042] The temperature control algorithm in the battery management system monitors the temperature of the battery in real time through the temperature sensor. When the temperature is lower than the set low temperature threshold, the heating device is activated; when the temperature is higher than the high temperature threshold, the cooling device is activated. The power of the heating and cooling devices is adjusted according to the difference between the battery temperature and the threshold.

[0043] The triggering judgment algorithm of the automatic alarm device comprehensively considers multiple factors such as data anomaly detection from the CPU, positioning deviation of the satellite positioning system, microwave signal interruption, etc. When any factor meets the preset alarm condition, the alarm operation is triggered. The alarm operation is executed in the preset alarm mode sequence, such as sound alarm first, then sending alarm information, etc.

[0044] The fusion positioning algorithm of the satellite positioning system fuses the satellite positioning data, the positioning data of the optical radar and the relative positioning data of the microwave signal device. By using data fusion methods such as weighted average, the weights are determined according to the reliability of each data source in different environments, so as to obtain more accurate positioning results.

[0045] The adaptive working mode algorithm of the optical radar determines the current lighting environment based on the data of the ambient light sensor. When the light intensity exceeds the strong light threshold, the laser emission power is reduced; when the ambient visibility is lower than the set low visibility threshold, the laser emission frequency and signal processing gain are increased. The above algorithms belong to conventional technologies in this field, so they are not described in detail here.

[0046] Therefore, this system achieves the following technical effects: 1. Integrate a variety of devices with different functions, such as high-performance multi-core CPU3, microwave signal device4, flash device5, parachute trigger device6, gyroscope balance device7, automatic alarm device8, satellite positioning device9, optical radar10, health monitoring device11, etc., to form a complete low-altitude flight support and function realization system. This integrated design reduces the complexity of the system and improves the collaborative work efficiency between various devices. For example, traditional low-altitude flight equipment may require multiple independent control units to manage different functions, while this system realizes seamless connection between various functions through unified management of high-performance multi-core CPU3; 2. Realize intelligent decision-making and emergency response. The CPU makes intelligent decisions based on data from various subsystems. In case of emergency, such as flight equipment failure, abnormal health monitoring data, or dangerous flight environment, the system can quickly respond to emergencies. For example, when the optical radar detects an impending collision and the gyroscopic balance device cannot avoid the collision by adjusting the flight attitude, the CPU can simultaneously trigger the parachute device and the automatic alarm device to ensure the safety of flight equipment and personnel; 3. Realize multifunctional data fusion and utilization. The system can integrate multiple data, such as satellite positioning data, health monitoring data, and light radar environmental perception data, and realize multiple functions based on these data. For example, based on satellite positioning data and health monitoring data, the ground control center can provide personalized flight advice to people in flight, such as reminding people with health problems to pay attention to environmental changes when approaching certain specific areas.

[0047] The working principle of the normal flight phase of the present invention is as follows: 1. After the CPU is started, it first obtains the initial position information of the flight equipment from the satellite positioning device and calculates the flight path according to the pre-set flight plan; 2. The gyroscopic balancing device 7 monitors the flight attitude in real time and transmits the data to the CPU. The CPU adjusts the control surface of the flight device according to the data to keep the flight attitude stable.

[0048] 3. The optical radar 10 continuously scans the flight environment and transmits the detected obstacle information to the CPU. The CPU adjusts the flight path based on this information to avoid collision.

[0049] 4. The health monitoring device 11 regularly collects the health data of the flight personnel and transmits it to the CPU through a microwave signal device. The CPU performs a simple analysis of the health data. If the data is normal, the flight will continue normally; if the health data is found to be abnormal, the CPU will trigger an automatic alarm device and decide whether to adjust the flight plan according to the situation.

[0050] 5. The microwave signal device 4 regularly sends flight data (including position, speed, flight attitude, health data, etc.) to the ground control center, and receives instructions from the ground control center (such as flight path adjustment instructions, etc.).

[0051] 6. The battery management system (BMS) of battery 2 continuously monitors the battery power, voltage, temperature and other parameters. If the power level is below a certain threshold, the BMS notifies the CPU, and the CPU decides whether to adjust the flight path to find a charging location or reduce the energy consumption of the flight equipment based on the flight plan.

[0052] The emergency situation of the present invention is handled as follows: If the flight equipment fails (such as engine failure, control surface failure, etc.), the gyro balance device detects an abnormal flight attitude, and the CPU determines the emergency measures based on the type and severity of the failure. If the failure is serious, the CPU triggers the parachute device to release the parachute, and at the same time triggers the automatic alarm device to send an alarm signal to the ground control center and relevant personnel.

[0053] If the health monitoring device detects that the flight crew's health condition is seriously life-threatening (such as sudden heart attack, severe hypoxia, etc.), the CPU immediately triggers the automatic alarm device, adjusts the flight plan, and performs emergency landing operations to ensure that the flight crew can receive timely treatment.

[0054] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
