Embodiment 1

[0028] This embodiment comprehensively analyzes the characteristics of electromagnetic radiation and conduction coupling of solar-powered drones and their equipped unit equipment. Specifically, solar-powered drones have a large distribution range of power supply equipment in addition to the limited load weight of general drones. specialty. The large distribution range of power supply equipment leads to a relatively large range of electromagnetic radiation, which will have a considerable impact on the installation position and shielding methods of wireless communication antennas. At the same time, in the processing of electromagnetic compatibility, it is also necessary to consider the influence of factors such as the structural strength, counterweight, load, aerodynamics, and measurement and control equipment of solar drones.

Abstract

The invention provides a platform load electromagnetic compatibility method based on a solar unmanned aerial vehicle and the solar unmanned aerial vehicle. The method comprises electromagnetic noise radiation compatibility design and electromagnetic noise conduction compatibility design. According to the electromagnetic noise radiation compatible design, a wireless communication antenna of the 30-512MHz frequency band is arranged on a tail beam of the solar unmanned aerial vehicle, and meanwhile, a safe distance is also reserved between the wireless communication antenna of the 30-512MHz frequency band and a steering engine. In this way, a wireless communication antenna larger than 600 MHz is arranged on a machine shell of the solar unmanned aerial vehicle. The electromagnetic noise conduction compatible design comprises the following steps: taking power from each unit device in the unmanned aerial vehicle in a nearby manner, and performing segmentation processing on multiple places such as a power supply ground, a protection ground, a digital signal ground and an analog signal ground at the same time. According to the method, the electromagnetic compatibility problem among variousunit devices of the solar unmanned aerial vehicle is solved, so that the wireless unit device is effectively carried, and the opening and normal operation of various services are ensured.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, and more specifically, to a method for electromagnetic compatibility of a platform carrier based on a solar unmanned aerial vehicle, and a solar unmanned aerial vehicle. Background technique [0002] Solar drones need a large number of solar power conversion modules and power management modules, and the low-frequency electromagnetic radiation caused by power conversion and management modules is very strong, and the electromagnetic radiation is mainly concentrated below 500MHz, which has caused serious damage to the airborne wireless unit equipment. Interference; at the same time, each wireless unit device can affect each other through the conduction coupling of power lines and signal lines. Therefore, it is necessary to conduct a comprehensive analysis of the electromagnetic compatibility characteristics of solar drones and propose corresponding solutions.
