Fault detection method and device for airborne geophysical prospecting system

Abstract

The embodiments of the invention provide a fault detection method and device for an airborne geophysical prospecting system. The method comprises the following steps that: for each subsystem in the airborne geophysical prospecting system, the state fault identifier of the subsystem is determined on the basis of the output quantity fault identifier of the subsystem; the fault identifier of each subsystem is determined based on the state fault identifier and communication interruption fault identifier of each subsystem; the fault identifier of the airborne geophysical prospecting system is determined on the basis of the fault identifier of each subsystem in the airborne geophysical prospecting system; and whether the airborne geophysical prospecting system malfunctions is determined on the basis of the fault identifier of the airborne geophysical exploration system. According to the method and the device provided by the embodiments of the invention, invalid measurement and invalid flightcan be avoided, and working efficiency is improved. The fault detection method and device are suitable for various airborne geophysical prospecting methods, and have the advantages of automatic performance, real-time performance, flexibility in setting and the like.

Description

technical field [0001] The invention relates to the technical field of fault detection, in particular to a fault detection method and device for an airborne geophysical prospecting system. Background technique [0002] Aeronautical geophysical exploration, referred to as aeronautical geophysical exploration, is a high-tech combination of geophysical exploration technology and aviation technology. Its essence is to use aviation aircraft as a carrier to load geophysical detection instruments to complete geophysical information measurement operations in the air. . Aerial geophysical prospecting has the advantages of high efficiency, low cost, and ease of large-scale work, and plays an important role in the fields of mineral and oil and gas resource investigation, basic geological survey, military and national defense construction, etc. Common airborne geophysical methods include airborne magnetic survey, airborne electromagnetic survey, airborne radioactive survey, airborne gr...

AI Technical Summary

Problems solved by technology

[0006] (1) The fault detection is inseparable from the ground monitoring system and the judgment of the staff, that is, it is not automatic fault detection in the true sense;

[0007] (2) Since it takes a certain amount of time for the staff to judge and send Beidou data, the real-time performance of fault judgment is limited;

[0008] (3) It can only be applied to a specific type of airborne gamma spectrum survey system, the scope of application is limited, and the portability is poor
