The all-optical-fiber bionic fish side line system comprises an optical sending module, a bionic fish side line optical fiber, an optical receiving module and a signal processing module. The bionic fish side line optical fiber is used for simulating the function of a fish side line system and sensing parameters such as water flow, water pressure, water sound and water temperature underwater; the bionic fish side line optical fiber comprises a cladding unit and a fiber core unit. The fiber core unit comprises a fiber core of a water body flow velocity fiber, a fiber core of a water flow acceleration fiber, a water sound fiber core and a temperature fiber core; the optical receiving module is used for receiving the optical signal transmitted by the optical fiber fish side line module, converting the optical signal into an electric signal and transmitting the electric signal to the signal processing module; the signal processing module is used for imitating the nervous system of the fish and intelligently processing and analyzing signals from the optical fiber fish side line module. The problems of poor directivity, single-point measurement and single function of a sensor in the prior art are solved.

Description

technical field [0001] The invention belongs to the field of bionic materials and bionic intelligent structures, and more specifically relates to a water velocity optical fiber, a water velocity optical fiber, and an all-fiber bionic fish lateral line system. Background technique [0002] Fish rely on their own lateral line system to perceive the characteristics of the fluid, and can know the flow direction and strength of the fluid, and then assist them to complete behaviors such as predation, learning, avoiding enemies, flocking, group swimming, and reproduction. The lateral line system is based on neuromasts distributed in different parts of the fish body, and senses fluid movement when the position of the body and the water flow changes during the swimming process of the fish. [0003] Fish sidelines are suitable for extremely complex underwater environments where optical, chemical, and acoustic detection methods fail, such as coastal, shallow seas, and waters densely co...
