Abstract
This paper presents the development of an air robotic system for monitoring the quality of ores in natural occurrence based on a specialized EDXRF device installed on a UAV equipped with technical vision. The sampling trajectory is selected using a depth camera. Electronic units were made and the designs of the main blocks of the structural diagram of the device were developed. The results are presented on the development and combination of the excitation and detection unit, as one of the main elements of the domestically produced specialized device (SD), which provides a significant expansion of the range of determined elements, an increase in the detection limit and the reliability of ore sampling in natural occurrence. On the basis of the developed main blocks and electronic components, a block diagram and a model of an energy-dispersive X-ray fluorescent device were developed on a modular basis, providing the necessary flexibility in adapting the device to various analytical tasks and unmanned aerial vehicles. Taking into account the developed technical and structural characteristics of the joint venture, a UAV was selected – a PX4 Vision quadrocopter equipped with technical vision with optimal characteristics. Based on the new developments of the structural scheme of the SD and its combination with the PX4 Vision quadrocopter, a model of an air robotic system for monitoring the quality of ores in natural occurrence was created, which will be used at mining enterprises in Kazakhstan. Research is being carried out within the framework of grant funding from the Committee of Science of the Ministry of Education and Science of the Republic of Kazakhstan for 2021-2023 in the priority area “Information, communication and space technologies” of the project AP09260493 “Development of a hardware and software complex of an air robotic system for monitoring the quality of ores in natural occurrence”.
