Embodiment Construction

[0020] The invention provides a new type of bionic lateral line sensor, which has a small structure and reasonable arrangement, adopts the bionic lateral line mechanism based on the principle of fish, has the advantages of being sensitive to fluid velocity, acceleration, force, impact frequency and amplitude, and can work underwater To sense the effect of fluid on the sensor, the bionic cilia with a special structure is used to replace the lateral line receptors of fish, which can not only directly detect the impact of fluid, but also have the function of sealing and waterproofing.

[0021] In order to better understand the above-mentioned technical solution, the above-mentioned technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0022] like Figure 1-Figure 7 As shown, a novel bionic lateral line sensor includes a housing 4, a clamp one 5, a clamp two 6, a fixing seat 8, a PU tube plug 9, a ...

Abstract

The invention provides a novel bionic lateral line sensor, and the application target is positioned as an underwater robot. The main function is to assist the underwater robot to perceive the fluid environment, including the perception of fluid velocity, acceleration, and fluctuation frequency. The underwater robot can adjust its operating posture autonomously by extracting the information obtained from sensor detection. The bionic principle of the sensor is based on the lateral line sensory organ of the fish. During the operation of the underwater robot, the impact of the water flow perpendicular to the direction of the bionic cilia transmits the force to the stress rod, and then further causes the deformation of the strain beam. The strain beam The detection element on the metal foil strain gauge detects the deformation of the strain beam, converts it into a voltage signal and transmits it, and finally can obtain the corresponding relationship between the change of the fluid and the change of the voltage signal. fluid state.

Description

technical field [0001] The invention relates to the technical field of underwater sensors, in particular to a novel bionic lateral line sensor. Background technique [0002] Natural light cannot penetrate below 1000 meters in the deep sea. In this dark environment, vision can no longer play a role. However, fish living in this environment can fly freely, hunt and avoid the pursuit of natural enemies. It relies on the lateral line organs of fish. The discovery of the fish lateral line system inspired scientists to sense the fluid environment by creating a bionic lateral line system. At present, there are very few research reports on the application of the lateral line sensing principle for underwater adaptive regulation on unmanned autonomous underwater vehicles. Contents of the invention [0003] The invention relates to a new type of bionic lateral line sensor, which has a compact structure and reasonable arrangement, adopts the bionic lateral line mechanism based on fi...
