Abstract

The invention belongs to the technical field of ground-air transient electromagnetic measurement by using a magnetic source, and particularly relates to a semi-aviation transient electromagnetic data real-time return method suitable for landslide detection, which comprises the following steps of: quickly flying by using an unmanned aerial vehicle platform, automatically combining channels and superposing in the air to obtain measured data of a KB level; and actually measured data are transmitted back to a ground receiving station in real time through wireless communication, so that the data can be conveniently processed in real time. Compared with a conventional method, the method provided by the invention can provide a quicker interpretation result in landslide geological disaster implementation measurement, and provides a basis for disaster control under an emergency condition of landslide geological disasters.

Description

technical field [0001] The invention belongs to the technical field of ground-air transient electromagnetic measurement using a magnetic source, in particular to a real-time return transmission method of semi-aviation transient electromagnetic data suitable for landslide detection. Background technique [0002] The semi-aviation transient electromagnetic method is launched on the ground, and the receiving system is mounted on the flight platform to achieve efficient and fast acquisition. It has a unified coordination between the detection depth and work efficiency. direction. The research shows that the ground-air transient electromagnetic method has great potential in the fields of minerals, oil and gas and geological disasters. [0003] Although domestic and foreign research and application experiments have been carried out in many aspects such as flight platforms, emission sources, data acquisition methods, and data processing in semi-aviation transient electromagnetic f...
