I. Introduction

With the rapid development of science and technology, drones are increasingly used in various fields, from aerial photography and entertainment to industrial inspection and agricultural plant protection. Low-altitude unmanned drones have attracted more and more attention due to their flexibility and efficiency. The solution developed based on STM32H730 equipped with DJYOS proposed in this study aims to provide new ideas and methods for the performance improvement and application expansion of low-altitude unmanned drones.

2. Hardware Configuration

1. Camera main board
The camera motherboard of the drone uses the rk1126 motherboard, which supports a 12-megapixel camera. This high-pixel camera can provide clear and delicate images, laying the foundation for the realization of machine vision. In terms of photography, it can capture rich details and colors, providing users with high-quality photo materials; in terms of video recording, the smooth picture and excellent picture quality enable it to meet the needs of various application scenarios, such as geographic surveying and mapping, film and television shooting, etc.

2. Flight Control System
The flight control system is the core component of the drone. This solution uses the flight control board developed by the stm32h730 solution and is equipped with an electric drive. The STM32H730 has the characteristics of high performance and low power consumption, and can quickly process a large amount of flight data to achieve precise attitude control and stable flight. The electric drive system provides efficient and reliable guarantee for the power output of the drone, ensuring the stable operation of the drone in various complex environments.

3. LiDAR Sensor
In order to ensure the safety of the drone during low-altitude flight, a laser radar sensor is equipped for obstacle avoidance. The laser radar sensor can quickly and accurately detect surrounding obstacles and feed back the information to the flight control system in real time, so that the drone can make evasive actions in time to avoid collision accidents.

(IV) Motor and body shell materials
Four brushless motors provide the drone with powerful driving force, ensuring that it can fly stably in different environments and missions. The fuselage shell is made of lightweight and technological materials, which not only reduces the overall weight of the drone and improves flight efficiency, but also the beautiful and transparent design increases the appearance of the drone.

3. Power and endurance

1. Battery performance
The 5000mha large-capacity battery provides sufficient energy support for the drone. After rigorous testing and optimization, the battery can support the drone to fly continuously for 16 minutes. This endurance has certain advantages among similar low-altitude unmanned drones and meets the needs of most users in a flight mission.

2. Energy Management
In order to extend the battery life and improve energy efficiency, the drone's power management system uses advanced technology. It can monitor battery power, voltage, temperature and other parameters in real time, and intelligently adjust the power output according to the flight status and load conditions to ensure stable power supply during the flight of the drone.

4. Control method

1. Remote control
The remote control supports manual remote control, providing users with an intuitive and convenient operating experience. The design of the remote control conforms to the principles of ergonomics, the button layout is reasonable, and the operation feels comfortable. Through the remote control, users can accurately control the flight attitude, speed, altitude and other parameters of the drone to achieve various complex flight actions.

(II) Mobile phone image transmission
Image transmission can be performed through mobile phones, allowing users to obtain images and videos taken by drones in real time. This function not only facilitates users to monitor and adjust the shooting content in real time, but also provides users with more creative possibilities. The stability and image clarity of mobile phone image transmission have been optimized and tested many times, and can maintain good performance in different network environments.

V. Conclusion

In summary, the low-altitude unmanned aerial vehicle solution developed based on the STM32H730 equipped with DJYOS has significant advantages in hardware configuration, power and endurance, and control methods. The successful application of this solution will bring new opportunities for the development of low-altitude unmanned aerial vehicles and provide strong support for the innovation and progress of related industries. However, in practical applications, continuous optimization and improvement are still needed to adapt to the changing market demand and technological development trends. In the future, we expect this solution to be widely used in more fields, bringing more convenience and innovation to human production and life.
