Abstract

The invention provides an underwater glider magnetic field characteristic test system, a data acquisition method and a test method, and belongs to the technical field of magnetic field characteristic test. The system comprises a three-axis fluxgate sensor used for collecting magnetic field data in three orthogonal directions; a magnetic field signal conditioning module which is used for receiving and processing magnetic field data output by the three-axis fluxgate sensor; an attitude sensor which is used for collecting attitude data of three axes of the three-axis fluxgate sensor; a data processing and monitoring subsystem which is used for checking and processing data in real time; and a main control module which is used for controlling the three-axis fluxgate sensor and the attitude sensor to synchronously acquire and receive the attitude data and the magnetic field data, performing data storage and recovery, and performing data transmission with the data processing and monitoring subsystem. According to the system, the magnetic field characteristics of the underwater glider can be accurately tested, and real-time monitoring of magnetic anomalies generated under static and dynamic conditions of the underwater glider can be realized in combination with a test method.

Description

technical field [0001] The invention belongs to the technical field of magnetic field characteristic testing, and in particular relates to an underwater glider magnetic field characteristic testing system, a data collection method and a testing method. Background technique [0002] The marine electromagnetic detection system is carried on the underwater glider, which can realize large-scale observation of the marine electromagnetic environment. However, when the underwater glider is moving and stationary, the internal magnetic components, power supply system, motion drive system, control system, etc. will generate magnetic field noise of different frequencies and strengths, and these magnetic field noises become an important source of interference for marine electromagnetic environment detection , which in turn affects the sensitivity of the marine electromagnetic detection system. Therefore, in order to increase the magnetic detection capability of the marine electromagnet...
