Embodiment 1

[0046] A detection system for underwater sunken ships, such as figure 1 As shown, it includes: a carrier platform 110 for flying above sea level, a signal processor 120 arranged on the carrier platform, a plurality of power frequency electromagnetic sensing devices and a plurality of servo systems (each power frequency electromagnetic sensor The sensing device and its corresponding servo system are composed of figure 1 Indicated by 130). Among them, a plurality of power-frequency electromagnetic sensing devices are arranged around a point, and each power-frequency electromagnetic sensing device is used to detect and perceive the sea level center of the sea area to be detected in real time under the independent drive of its corresponding servo system. The sea area of ​​any radius area within the preset fan-shaped sea level range with the center of the circle, each preset fan-shaped sea level range has no overlap and the sum of the central angle θ is less than or equal to 360 d...

Embodiment 2

[0069] A detection method for an underwater shipwreck, using any detection system for an underwater shipwreck as described in the first embodiment above, and performing the following detection steps:

[0070] Control the carrier platform in the detection system to fly above the sea level, and control the servo systems in the detection system at the same time, so that the real-time and synchronous detection and perception of each power frequency electromagnetic sensing device can be centered on the sea level center of the current sea area to be detected Sea areas within any radius area within the preset fan-shaped sea level range, each preset fan-shaped sea level range does not overlap and the sum of the central angles is less than or equal to 360 degrees;

[0071] Control the signal processor in the detection system to process the power frequency electromagnetic signals collected by each power frequency electromagnetic sensing device in real time, obtain the total power frequen...

Abstract

The invention belongs to the field of underwater target detection, and specifically discloses a detection system and detection method for underwater shipwrecks. The system includes: an aircraft carrier platform used for flying above sea level; Arranged in a circle, and each power frequency electromagnetic sensing device is used for real-time independent drive of its corresponding servo system to detect and perceive any radius area within the preset fan-shaped sea level centered on the sea level center of the current sea area to be detected In the sea area, each preset fan-shaped sea level range has no overlap and the sum of the central angles is less than or equal to 360 degrees; the signal processor is used to process the power frequency electromagnetic signals collected by each power frequency electromagnetic sensing device in real time, through processing and combining with the background power frequency Electromagnetic signal comparison to identify the sunken ship area. The present invention combines the frequency band advantages of power frequency electromagnetics and the sensor array detection system to give full play to the overall performance, thereby improving the wide-range scanning perception ability of underwater sunken ships, and breaking through the limitations of the detection range and relatively large interference noise.

Description

technical field [0001] The invention belongs to the field of underwater target detection, and more specifically relates to a detection system and detection method for underwater shipwrecks. Background technique [0002] With the rapid advancement of economic globalization, the exchanges between countries in the world are becoming more and more frequent. In order to carry out economic communication and cargo exchanges between countries, the advantages of ocean transportation, such as large volume and convenient waterways, have become the first choice for cargo transportation in various countries. Transportation trends. However, human beings are often insignificant in the face of natural forces. Maritime navigation will encounter many emergencies, those unexpected environmental disturbance factors (tornado, glaciers, reefs, etc.) will lead to accidents, and then maritime clearance and salvage, emergency rescue has become a public emergency emergency rescue A pivotal task in ...
