Description

technical field [0001] The invention relates to the technical field of information transmission systems, in particular to an FPGA-based unmanned aerial vehicle information transmission system. Background technique [0002] The digitalization of information and the development of the network have greatly improved people's ability to process and transmit information. Traditional methods of information processing and transmission have been unable to meet people's requirements for information. For communication systems, the effectiveness of information Sexuality is an important feature of it. The time delay of the obtained information will have a huge impact on its effectiveness, and sometimes even have a negative effect. The current single-machine flight of the drone may lead to this situation. , and the working method of UAV networking can greatly improve this problem. [0003] However, the development of UAV systems in my country still faces many challenges. For example, th...

[0002] The digitalization of information and the development of the network have greatly improved people's ability to process and transmit information. Traditional methods of information processing and transmission have been unable to meet people's requirements for information. For communication systems, the effectiveness of information Sexuality is an important feature of it. The time delay of the obtained information will have a huge impact on its effectiveness, and sometimes even have a negative effect. The current single-machine flight of the drone may lead to this situation. , and the use of UAV networking can greatly improve this problem

[0003] However, the development of UAV systems in my country still faces many challenges

For example, there are still difficulties in mastering complex drone technology. my country has exhibited many drone models at the Zhuhai Air Show, but has not mass-produced physical machines. The development of drones in my country lags behind the needs of the army. However, the reconnaissance methods are still relatively backward. In the Hanchuan earthquake, in order to search and rescue the crashed helicopter, tens of thousands of people were sent into the mountain to search. During the search and rescue process, a militiaman unfortunately died

In addition, my country is still in the initial stage of research and development of UAV broadband data links. Compared with foreign countries, the transmission rate is low, the link capacity is small, point-to-point is used in isolation, and the degree of networking from point to surface has not yet been reached. Seriously restricts the effectiveness of UAV systems

[0004] From the perspective of the overall development, all units and services are still in a state of fragmentation, lack of unified planning and design, lack of clear roadmap for equipment performance, and the versatility of the platform and the modular development of the system are far behind the world's advanced level. Compared with Europe and the United States, the future development direction and positioning of UAVs are not yet clear
