Underwater monitoring device and method based on beam forming technology

Abstract

The invention provides an underwater monitoring device and method based on a beam forming technology, and the device comprises a main console and two frogman detection sonars, and the main console comprises a processor, a memory, a communication module, a power module, and an alarm module. The frogman detection sonars are respectively arranged on underwater quay walls at two sides of a port and are in two-way communication with the main console; each frogman detection sonar comprises a transmitting transducer, a receiving transducer, a control module, a storage module, a communication module and a power supply module; each frogman detection sonar further comprises a frogman recognition unit and an infrared recognition unit, the frogman recognition unit comprises a first recognition module, a calculation module, a second recognition module and a target sample library, and the infrared recognition unit comprises an infrared camera and an image recognition module. According to the underwater monitoring device and method based on the beam forming technology provided by the invention, the water area near a port can be comprehensively monitored, and the type of the underwater target to be detected can be accurately identified.

Description

technical field [0001] The application belongs to the technical field of underwater acoustic detection equipment, and in particular, relates to an underwater monitoring device and method based on beamforming technology. Background technique [0002] In recent years, with the continuous development of the field of marine exploration and development, ports and seaports have become important targets of attack. In open state-to-state warfare, mines are effective at deterring underwater sneak attacks; but in today's ongoing non-war conflict, dangerous underwater targets need to be detected in advance so that effective measures can be taken—politely Ask the opponent to leave, or fight back with a deadly attack. [0003] In response to the above monitoring requirements for underwater targets, technologies such as frogman detection sonar and anti-frogman detection equipment are also constantly developing. Among them, in the prior art, the frogman detection sonar based on the beamf...

AI Technical Summary

Problems solved by technology

[0004] However, there are errors and many influencing factors in the actual application of the above-mentioned frogman detection sonar. For example, the existing frogman detection sonars all have short-range blind spots, and cannot detect and detect underwater targets that break through their monitoring range and enter the short-range blind spots In addition, various fish and other marine life may also be mistakenly identified as dangerous underwater targets, resulting in false positives
