A device for comparing and testing the performance of a magnetic anomaly sensor in a deep sea environment comprises a standard magnetic anomaly sensor (1), a to-be-compared-and-tested magnetic anomaly sensor (2), a standard magnetic anomaly signal generator (3), a fixing support (4), a standard magnetic anomaly sensor fixing cover plate (5), a standard magnetic anomaly sensor upper hoop (6), a standard magnetic anomaly sensor lower hoop (7), ato-be-compared-and-testedmagnetic anomaly sensor fixing cover plate (8), a standardmagnetic anomaly signal generator fixing cover plate (9) and astandard magnetic anomaly signal generator clamp (10). The device is applied to a deep sea environment with high water pressure, high corrosion and low temperature, and has the characteristics of light weight, high strength and corrosion resistance.

Description

technical field [0001] The invention belongs to the field of sensor testing, and in particular relates to a performance comparison measurement device and a comparison measurement method for a magnetic anomaly sensor in a deep-sea environment. Background technique [0002] Magnetic anomaly detection technology is a detection technology to detect the disturbance and change of the static magnetic field. The earth itself is a huge magnet, and it is generally believed that the spin of a large amount of ferrous fluid inside it produces a geomagnetic field, thus forming the north and south magnetic poles of the earth. Although the position of the magnetic poles is moving every year, and the strength of the geomagnetic field will also change, or even reverse, but in most of the time, the signal of the geomagnetic field is very stable, which can be regarded as a stable, static state. magnetic field. Magnetic anomaly detection technology measures the gradient anomaly caused by the c...

Problems solved by technology

At present, some sensors have been developed, but in terms of detection, due to the lack of industry standards, no clear detection methods and detection equipment have been formed. There is still a long distance from standardization and standardization, and there is still a standard signal source in the deep sea environment. Difficult to find, difficult to accurately control the detection distance and many other problems
