Embodiment 1

[0031] Embodiment 1: For the convenience of explanation, we illustrate the implementation process of the present invention with a cuboid plexiglass water tank simulation as the target detection area. A certain amount of tap water is injected into the water tank, and its conductivity is about 340 μS / cm, and the water surface height is greater than that of the experimental object (target measured object) height. Adjust the position of the detection device so that the transmitting electrode and the receiving electrode are immersed in the water, and ensure that the two electrodes will not collide with the experimental object during the movement of the device. Select a metal aluminum cylinder (with a size of Φ20mm×40mm) as the measured object, and place it at any position at the bottom of the cuboid tank container. Specifically, in this embodiment, the measured object is placed on a length×width two-dimensional plane The middle coordinate is (15cm, 20cm), the specific object size a...

Abstract

The invention relates to the underwater active positioning field and particularly relates to an underwater two-dimensional space active electric field positioning method based on a particle swarm optimization algorithm. According to the method, a detected object is positioned through an underwater active electric field, especially for a metal object, influence of complex factors including darkness and turbidity of the underwater environment can be solved, and detection reliability and validity are improved. Starting from the basic theory of an electromagnetic field, an active electric field positioning mechanism of a light current fish is simulated, underwater positioning precision is improved to a millimeter magnitude level, moreover, a local optimal deadlock can be avoided, underwater detection validity and searching optimization are improved, the method is suitable for commercialization development, as underwater detection steps are gradually accelerated, underwater positioning technology requirements are wider and wider, and relatively good business development prospects and application values are realized.

Description

technical field [0001] The invention relates to the field of underwater active electric field positioning, in particular to an underwater two-dimensional space active electric field positioning method based on a particle swarm optimization algorithm. Background technique [0002] With the rapid development of productivity and the continuous advancement of science and technology, people's pace of exploring the ocean is accelerating, and underwater detection technology is gradually developing. Weak electric fish can sense the external environment by establishing a low-frequency electric field underwater, which we call active electric field localization. [0003] The mystery in the body of the weakly electric fish has not only aroused the interest of biologists, but also attracted the attention of bionic researchers. In recent years, based on the idea of ​​active electric field positioning of weak electric fish, engineers have begun to study how to make active electric field p...
