An agricultural drones are gradually increasing in utilization due to economic efficiency, and consist of a main frame in charge of flying spray system in charge of moving pesticide to control targets. Therefore, the environment and characteristics of crops should be considered when controlling pesticides using drones and conditions such as systematic flying altitude of flight, speed, and spray time should be changed accordingly. However, pest control work using agricultural drones has different spray effects depending on level the operation proficiency and spray impact. In addition, there are variations in operating standards and control efficiency for agricultural drones, which hinder the distribution of agricultural control drones in the field of pest control work. Therefore, this study attempts to identify the spraying characteristics of agricultural drones, apply the effective spraying time, interval and experimentally verify the system that can calculation of spray area compared to previous studies. Through this experimental verification, it is intended to apply the optimal control process by minimizing the obstacles to pest control work by applying the operation method and systematic figures to agricultural drones.

In the recent farming industry, there is a growing diffusion of drones, which are recognized as a crucial technology of the 4 th industrial revolution to cope with aging. Especially, filming and pest control using drones are representative fields that have different age groups for obtaining a national license of multicopter that is a ultra-light flying device, and can create profits after getting a license. However, pest control technology using drones has different spray effects depending on levels of operational proficiency, since this highly relies on an operator's operating skills. It is anticipated that if this issue is supplemented, the use of drones for pest control in the farming industry will diversify. For analysis of spraying characteristics of agricultural pest control drones, this study aims to formulate effective spraying hours and effective spraying intervals and suggest an algorithm, which facilitates an accurate calculation of pest control area depending on the kinds of pest control drones. This algorithm can be used in the field of pest control by improving scatterling issues caused by drone flight methods of drone pest controllers and building an optimum pest control manual in future.

Recently, interests in the 4th industry have increased the level of demand for pest control by farmers in the field of rice farming, and the interests and use of agricultural pest control drones. Therefore, the diversification of agricultural control drones that spray high-concentration pesticides and the increase of agricultural exterminators due to the acquisition of national drone certifications are rapidly developing the agricultural sector in the drone industry. In addition, as detailed projects, an effective platform is required to construct large-scale big data due to pesticide management, exterminator management, precise spraying, pest control work volume classification, settlement, soil management, prediction and monitoring of damages by pests, etc. and to process the data. However, studies in South Korea and other countries on development of models and programs to integrate and process the big data such as data analysis algorithms, image analysis algorithms, growth management algorithms, AI algorithms, etc. are insufficient. This paper proposed an online drone pest control management information platform to meet the needs of managers and farmers in the agricultural field and to realize precise AI pest control based on the agricultural drone pest control processor using drones and presented foundation for development of a comprehensive management system through empirical experiments.

The utilization of agricultural drones for pest control operations has been increasing due to its economic efficiency. However, variations in the effectiveness of these operations occur depending on the operator's proficiency. In this study, we applied a smart operating mode to overcome the limitations of manual flight mode and proposed a numerical model. Through comparative validation with prior research, we conducted experimental verification. As a result, we determined the spray time and calculation of spray area for each drone model. We selected a drone for pest control with a high similarity to the numerical model and verified it experimentally. Through this, we confirmed that the application of the smart operating mode is more effective in terms of calculation of spray area and operational efficiency compared to manual flight mode.

This study aims to determine how agricultural drones are operated for flight tests using a 5G communication in order to carry out a mission such as sensing agricultural crop healthy status with special cameras. Drones were installed with a multi-spectral and IR camera to capture images of crop status in separate altitudes with different speeds. A multi-spectral camera can capture crop image data using five different particular wavelengths with a built-in GPS so that captured images with synchronized time could provide better accuracy of position and altitude during the flight time. Captured thermal videos are then sent to a ground server to be analyzed via 5G communication. Thus, combining two cameras can result in better visualization of vegetation areas. The flight test verified how agricultural drones equipped with special cameras could collect image data in vegetation areas.

High-resolution images taken by drones are being used for a variety of information, including monitoring. The management of agricultural facilities still uses mostly human survey methods. Surveying agricultural facilities, surveying the appearance of agricultural facilities, and the sleeping environment have legal and environmental constraints that are inaccessible to humans. In addition, in an area where information such as 3D maps and satellite maps are outdated or not provided, human investigation is inevitable, and a lot of time and money are invested. The purpose of this research is to design and develop drone system for field support incorporating AR smart glasses technology for the maintenance and management of agricultural facilities to improve the difficulties of using existing drones. In addition, We will also suggest ways to secure the safety of personal information in order to solve the damages caused by the exposure of personal information that may occur through video shooting.

In relation to $4^{th}$ industrial revolution, it is required to build a smart agricultural system using the pest control drones, which are emerging fast these days as a role to support pest control work of farmers and improve aging issues in farming. However, the absence of accurate criteria on management of the pest control drones and the effect of pesticide application is leading to damage to crops by pesticides. The extreme shortage of analysis of management of the pest control drones and relevant studies, and big differences in pest control efficiency depending on the operation skills of controllers are the biggest reasons for the damage. Therefore, this paper suggests a basic study on agricultural pest control drone operation system buildup to make out working schedules and calculate the dosage of pesticide by understanding the features of the pest control drones properly based on the control using smart operating mode.

A drone invented for the military has been increased the range of application with the development of relevant technology, and it influences to include the private area. Currently, the use of drone has been increasing in many areas, such as agriculture, unmanned parcel service, production of image contents, and architecture. In 2021, South of Korea, a drone certificate system for drone flight is introduced and on operation. In case of drone flight with the maximum takeoff weight as 2kg or up, the flight experience and practical examination are required, whereas in case of drone lighter than 2kg, the online education qualification is enough to operate it without the flight experience and practical examination. Recently, the drone related accidents have been increasing with the rapidly supply of camera drones with the maximum takeoff weight as less than 2kg. This paper introduces the characteristics of the camera drone to meet burgeoning demand, and discusses an education plan for the camera drone.

최근 물 사용에 대한 각 부문 간의 경쟁이 심화되고 있으며, 미래 기후변화에 대응하기 위해 체계적이고 효율적인 수자원 활용이 요구되고 있다. 농업용수는 우리나라 수자원의 40% 이상을 차지하고 있지만, 생활용수, 공업용수와 달리 경험에 기반한 관행적 관리가 이루어지고 있어 체계적인 관리가 필요하다. 농업용수의 체계적 관리와 분석을 위해 최신화된 수혜면적 파악 및 수혜구역 내 수로 네트워크 구축은 필수적 요소이다. 현재 활용하고 있는 농업용 저수지 수혜면적 및 수로 자료는 한국농어촌공사의 RIMS 자료를 기반으로 하고 있다. 하지만 기존 자료의 경우 준공 당시 설계기준으로 작성되거나 수년 전 갱신된 자료로 최신현황을 반영하지 못하고 있다. 이러한 문제점을 보완하기 위해 직접 측량을 통한 자료 취득 또는 농림축산식품부의 스마트팜맵과 같은 대체, 보완자료가 활용되고 있다. 직접 측량의 경우 최신화된 정확한 자료 취득이 가능하지만, 많은 시간이 소요되며, 스마트팜맵의 경우 취득 주기가 1~2년으로 주기에 따라 최신자료의 활용이 어려울 수 있다. 본 연구에서는 자료 산정 시간 단축 및 최신자료 취득을 위해 고해상도 영상을 활용하고자 하였으며, 여주시 삼합저수지를 대상으로 검증하였다. 영상자료로는 위성영상, 항공영상, 드론영상을 활용하였으며, 위성영상의 경우 구글어스 프로의 2020년 11월 고해상도 영상, 국토리지정보원의 2019~2020년 51cm급 항공 영상, 2020년 10월 촬영한 4cm급 드론영상을 사용하였다. 수혜면적 산정은 기존 RIMS 자료와 스마트팜맵을 통해 확인한 수혜면적에서 영상을 통해 확인한 토지이용 변경지역을 추출하여 재산정하였으며, 수로 네트워크의 경우 RIMS 자료를 기반으로 드론영상을 통해 확인된 수로 추가 및 DEM (Digital Elevation Model) 영상을 활용한 용수 흐름도 작성을 통해 구축하였다. 본 연구에서 재산정한 수혜면적과 수로 네트워크는 정확한 용수 수요량 및 공급량 산정, 관개 효율 분석 등과 같은 농업용수 분석 전반에 기초자료로 활용 가능할 것으로 판단된다.
