Airship long-endurance random measuring point three-component aviation wide-area survey system

Abstract

The invention discloses an airship long-endurance random measuring point three-component aviation wide-area survey system, and the system comprises a task command module, a flight module and a load equipment module. According to the invention, aerial wide-area survey operation can be realized, and a plurality of problems of ground operation, such as personnel safety, operation efficiency, even personnel inaccessibility and the like, are solved. The system has large load, can carry multi-task equipment, can carry a three-component sensor to obtain a three-component magnetic field vector and a sensor attitude, thereby solving the influence caused by the low-frequency attitude change of the aircraft hanging basket. The system is particularly suitable for plateau and large-range survey engineering operation, long-endurance operation can be achieved through one-time take-off and landing, and therefore the overall engineering efficiency is obtained. Besides, under the monitoring of the taskcommand module, the effectiveness and completeness of the acquired data are guaranteed, and a reliable data basis is provided for later geological analysis.

Description

technical field [0001] The invention relates to a three-component aerial wide-area survey system with random measuring points during long endurance of an airship, and belongs to the technical field of aerial geophysical prospecting. Background technique [0002] The wide-area electromagnetic method has been applied in geophysical engineering practice and is one of the more common and effective means of geological survey in the industry. In many years of application, the electric method is the main method, and the method of placing metal electrodes on the ground is used to collect the information of the earth's electric field. This method requires engineering and construction personnel to traverse all measuring points on foot, retract electrodes and cables. In this way, a large number of metal electrodes, cables, and equipment need to be carried. For harsh operating environments, especially plateau deep valleys and dense forests, safety, efficiency, cost and even engineerin...

AI Technical Summary

Problems solved by technology

Although rotor UAVs can operate at low speed, continuous low-speed operation causes the aircraft to continue to be in a state of high power output, and its flight time and range are greatly affected

[0007] 2. Time limit

Immediately adopting gasoline-powered or gasoline-electric hybrid UAVs, the improvement of this situation is relatively limited, especially in the plateau environment with low oxygen-deficient air density, the efficiency of fuel engines drops sharply

[0008] 3. Load and space

But this is only enough to mount a single sensor

High altitude operation, UAV performance is greatly reduced

If a three-component sensor is mounted, or in order to obtain a greater range and flight time, a large oil-powered drone (commercial load 30-50 kg) can also be used, and such drones are mostly used for cargo or plant protection applications, and plateau scenarios There are very few commercial applications, so civilian products are not easy to obtain and are not suitable for engineering promotion
