[0002] In recent years, with the continuous maturity of UAV technology, in view of its characteristics of less casualties, low cost, high efficiency, and the advantages of predictable high-precision data, low noise level, and high spatial resolution, UAV aeromagnetic The R&D and application of the UAV geophysical survey system have increasingly attracted the attention of various aviation geophysical companies in the world. The development of UAV aerial geophysical survey system has been started in the world since 2003, but it started relatively late in China. From 2008 to 2011, the 715 Institute of CSIC , the Institute of Remote Sensing and Digital Earth of the Chinese Academy of Sciences, the China Land and Resources Airborne Geophysical Prospecting and Remote Sensing Center, and Lawrey Industries have successively carried out research work based on fixed-wing UAV aeromagnetic measurement technology, and have achieved certain research results, but It has not been applied to actual measurement work. In 2012, Peking University and other units also carried out special research in this area, and obtained a certain amount of experimental data, but it has not been popularized and applied. The multi-rotor unmanned aerial vehicle developed by Judeng Exploration Company The machine is equipped with a fluxgate magnetometer system, which is light in weight but low in accuracy. In 2013, the Geophysical Research Institute broke through key technical problems such as UAV system modification and integration, and magnetic compensation, and successfully realized China's first domestically produced medium-sized fixed-wing UAV. The aeromagnetic measurement system fully considers the impact of aircraft modification on aerodynamics and how to obtain high-quality aeromagnetic data. With reference to the appearance of the time-domain avionics pod currently being developed by the Institute of Geophysical and Geochemical Exploration, this kind of probe cabin is designed. , such as the patent application number: CN201811628724.5, the application publication number is CN109709615A, and the name is a kind of airborne magnetic measurement system for rotor drones, including a cover, a central processing module, a casing and an optical pump magnetometer. An organic cover is installed at one end, and a circuit board is installed on one side of the inside of the casing through a first fixing bolt, a central processing module is installed at one end of one side of the circuit board, and a wireless signal transceiver module is installed at the other end of one side of the circuit board , the top of the casing is equipped with an optical pump magnetometer, and one side of the optical pump magnetometer is provided with a display screen, and one end of the top of the optical pump magnetometer is equipped with a solar panel through a carrier frame, and the solar panel is below A storage battery is installed inside the carrier frame, but the disassembly and installation of this patent are too complicated for use, and it is inconvenient to operate, and this patent cannot be adjusted in length, so it is inconvenient to use, and when the magnetic probe needs to be fixed, It cannot be adjusted according to the width of the magnetic probe, and it is not convenient to adjust the angle, and the existing level adjustment device needs to be manually completed by the staff, so it is difficult to adjust
