Description
Technical Field
The utility model relates to a technical field is gathered in the aerial survey, specifically is a light-duty fixed wing unmanned aerial vehicle aeromagnetic main field and horizontal gradient measurement system that hangs down.
Background
The aviation magnetic detection (referred to as aeromagnetic detection for short) is firstly used for detecting magnetic anomaly caused by submarines by naval and then used for civil aviation physical exploration. Along with the maturity of application technology, the application of unmanned aerial vehicle in the aeromagnetic detection is showing to increase, unmanned aerial vehicle carries on aeromagnetic detection equipment and can deploy fast, high efficiency, the data collection of high accuracy, develop large scale aeromagnetic operation not only can eliminate the influence that interferent and relief topography such as ground earth's surface produced, fully save the cost, and also can be in geological environment and the environment that safety standard forbids manned aircraft magnetism survey system, undertake the detection task and even can obtain the detection data of better quality than manned aircraft aeromagnetic system, not only can acquire the earth magnetic total field intensity of observation point, can also obtain the difference of earth magnetic field between two probes, realize aviation horizontal magnetic gradient measurement promptly, improve magnetic anomaly resolution and explain the effect.
The magnetometers mainly used in the market at present are three-axis fluxgate magnetometers, proton magnetometers, Overhauser magnetometers, optical pump magnetometers and superconducting quantum interference magnetometers. Proton/overhauser, optical pump magnetometer. Proton magnetometer and Overhauser magnetometer are less used for aviation magnetic measurement due to the limitations of working mode, gradient tolerance, sampling rate and the like. The aviation magnetic measurement is limited by various factors such as a detection principle, a probe material, a volume, a weight, a sampling rate, a price and the like, the optical pump magnetometer is mainly used for the commercial aviation magnetic measurement at present, and the triaxial fluxgate magnetometer is used as a compensation or three-component measurement auxiliary.
Due to the characteristic of being particularly sensitive to the magnetic component, the aeromagnetic system has a special requirement on the platform selection of the unmanned aerial vehicle, and the low magnetism, the flight characteristic and the endurance time of the unmanned aerial vehicle are one of the key factors of the actual aeromagnetic operation. In the existing market, the unmanned aerial vehicle can be roughly divided into single rotor, multi-rotor and fixed-wing unmanned aerial vehicles. Single rotor unmanned aerial vehicle structure is complicated, and spare part is numerous many, and research and development cost is very high, and the cycle is very long, and the maintenance is inconvenient, and is very high to the requirement of operative employee. Many rotor unmanned aerial vehicle control and production easily, but the biggest problem is that duration is than relatively poor, and flight distance and scope have also received very big restriction. Although the ordinary fixed wing unmanned aerial vehicle has strong cruising ability and higher speed, the unmanned aerial vehicle takes off and lands on flat terrain or a special runway, and is obviously not a proper choice for geophysical prospecting services such as mineral exploration and the like which need field operation. The mode of a vertical fixed wing unmanned aerial vehicle appears in the market and the technical field at present, a multi-shaft power unit is added on the basis of a conventional fixed wing aircraft, the vertical fixed wing unmanned aerial vehicle flies or hovers in a multi-shaft mode in the take-off, landing and low-speed states, flies in a fixed wing mode in the flat flying state, overcomes the gravity through aerodynamic lift, and greatly improves the flight time and speed. But because a plurality of magnetic devices such as motors, electric modulation devices and the like need to be added. The vertical fixed wing unmanned aerial vehicle carrying aeromagnetic system needs certain layout design, selection and modification to meet the requirements, and the vertical fixed wing unmanned aerial vehicle specially designed for the aeromagnetic system does not exist in the current market.
The prior aeromagnetic system needs to comprise a GPS, an optical pump magnetometer, a three-axis fluxgate magnetometer, a collector and other devices, and has larger volume, and the total weight is generally more than 5 kg. Therefore, the requirement on the load capacity of the unmanned aerial vehicle platform is high, and the expensive large-scale fixed wing unmanned aerial vehicle platform in the million/million level or the unmanned helicopter platform is adopted in the market for carrying.
Secondly, many commercial optical pump magnetometers and aeromagnetic compensation equipment are imported, the price is very high, and meanwhile, the mainstream high-precision optical pump magnetometers in the market belong to sensitive equipment, and the import is restricted by people.
Furthermore, according to the relevant laws and regulations in the state at present, an unmanned aerial vehicle with an empty weight of more than 4kg and a takeoff weight (including a battery) of more than 7kg belongs to the unmanned aerial vehicle above class II, and no matter whether the unmanned aerial vehicle flies in a sight distance or not, an airspace needs to be applied in advance. And when the weight is lower than the weight requirement, the aircraft flies in the flight-suitable airspace and the sight distance, and only needs to report to the supervision platform in real time without applying for the airspace in advance. The popularization and application of the aeromagnetic measurement system of the optical pump magnetometer are greatly limited under the conditions, at present, main research and technology are concentrated in national projects such as universities and national scientific research institutes, and truly marketable products do not exist.
