1. Introduction

When it comes to drones, people seem to be familiar with them. For example, during the COVID-19 pandemic, drones are used to shout, and drones are used to manage traffic on traffic, and drones are used to perform military missions.. Big data,The advent of the 5G era has made the development of drones more intelligent, andDrones appeared earlierWorld War Imiddle,U.KTwo generals, Cadel and Pichel, develop radioControlsmall aircraft, make itUnder radio controlFly to a certainTargetOver the sky,Carry out related military activities. With the development of the big data era, the performance of drones has become more perfect. UAVs can be divided into two categories, namely military and civilian. Military uses are mainlyreconnaissance aircraft、target drone，CivilianYesDrone+Industry applications，Compared with military and civilian use, it develops more rapidly。Drones in all walks of lifeApplications,AllIt has greatly expanded the use of the drone itself, many countriesIt is also actively expandingDroneIndustry application and development of drone technology.This article usescitespace software performs visual analysis to obtain relevant visual knowledge maps, and then completes the analysis and mining of hot spots in drone research, providing direction for its development.

2. Data analysis

From Figure 1 and Figure 2, it can be seen that the number of publications on drone research is increasing every year, although there will be some fluctuations abroad.Domestic drone marketFrom the beginning to the presentAlmost developed30manyYear, from the beginningOnly applied tomilitarycasefieldNowGradually expand toCivilianfield. Domestic drone marketDevelopment in full swing, the degree of support and demand for drones by the publicalsoGradually climb，pastOver the past few years, drone productsalsoThere has been a significant increase, and there has been even an exponential growth.The country isThe regulatory system has also been further improved.Some foreign countries, such as the US militaryWill promote drone cluster research mission，Daily Mailsay,beautifulMilitary approval4 companies develop a drone that works in group collaborationPlan to replace humans with dangerous tasks, and hope to use them to be largerreduceCost of use of multi-function fighter。

Driven by information technologies such as the Internet of Things, big data, artificial intelligence, and cloud computing, the fourth scientific and technological revolution is ready to go, and at the same time, the scientific and technological revolution also provides strong information technology support for the development of drones. The in-depth application of data analysis technology will enable drones to achieve rapid management and provide excellent services, and new ecology, new models and new applications of drones will continue to come to your eyes.

The development context of the drone research field can be intuitively seen from the hot topics of drone (Figure 3) and the evolutionary visual map (Figure 4). Through the content of the article and combined with the visual knowledge graph (as shown in Figure 4), drone research and analysis can be divided into two stages:

(1) The first stage is the stage of introducing drone-related concept technologies. Researchers analyze the relevant theoretical knowledge and potential value of drones, and vigorously build drone research algorithms, such as neural networks, deep learning, etc.

(2) The second stage is the stage of deepening and application of drones. Researchers have proposed concepts such as intelligence of drones and drone peak groups, striving to promote the development of drones, build a complete drone ecosystem, and develop drone power systems.

The "Plan for the Development of New Generation Artificial Intelligence" points out the importance of human-machine collaboration under the driving force of big data, and strengthens the construction of intelligent technologies with independent unmanned systems. Focus on breaking through cutting-edge technologies such as drone system algorithms, dynamic perception, and rapid positioning. Figure 5 shows the knowledge map of domestic drone research institutions in my country. From the perspective of the issuing institutions, the School of Automation of Nanjing University of Aeronautics and Astronautics, the School of Astronautics of Beijing Institute of Technology, Nanjing University of Posts and Telecommunications, and the School of Computer Science and Engineering of Northwest Normal University have issued a large number of documents (see Figure 5). From the nature of the issuing agency, we can see that the better research institutes are an indispensable force in the current drone research.

3. Conclusion

This article is about drones as the theme, and the literature data on the development of drones in China National Knowledge Infrastructure database from 1980 to 2021For research objects, useCitespace visualization software draws scientific knowledge graphs and uses a field of bibliographic measurement methods for common word analysis and word frequency analysis to conduct in-depth analysis and discussion on the number of documents published, hot spots found in related research, and the evolution trends of hot spots. Its visual map can provide a reference for drone research. The research found that with the development of the times and the deepening of drone-related research,DroneThe word " has entered people's research field,With the in-depth application and promotion of cutting-edge technologies such as big data and artificial intelligence in the development of drones, it has prompted that drones will develop towards intelligence to become an inevitable trend. Thus aroundThe characteristics and advantages of 5G communication technology are formulated from infrastructure to application system to management system to digital and intelligent systems to complete the improvement of drone quality to achieve smart services.
