Problems solved by technology

This method can ensure the speed and accuracy of information transmission, but because the cable cannot be too long, the range of motion of the robot fish is limited, and it can only swim around the ground console
Therefore, the existing information transmission methods are difficult to meet the requirements of large-scale movement of robotic fish

Embodiment

[0028]According to the system structure and connection relationship described in the present invention, a water surface information relay device applied to the underwater bionic robot fish 1 is fabricated. Sinonuo SV series video image optical transceiver (including optical transmitter 3 and optical receiver 16) and ST interface optical cable 8 are used, and the high-frequency wireless sending module 17 and high-frequency wireless receiving module 11 adopt the 4-channel series of Navigator. Use the MAX232 chip to make a protocol level conversion module (including module (M1)5, module (M2)13), and select Huaronghui GW100A as the low-frequency wireless module (W1)12, (W2)14. Water surface buoy 9 adopts hard plastics to make, and lithium rechargeable battery is as power supply 6,15. Each part of the present invention is correspondingly installed inside the robot fish, the water surface buoy and the ground console, and after the robot fish and the water surface buoy are sealed wit...

Abstract

A water surface information relay system of bionic machinery fish comprises two portions of video information relay and digital signal relay. The video information relay portion consists of light emitter and receiver, optical cable, high frequency radio transmission module, double-ring antenna, high frequency radio receive module, etc.; the digital signal relay portion comprises protocol level conversion modules M1 and M2, low frequency radio modules W1 and W2. It is featured as setting the light emitter and the level conversion module M1 in machinery fish; setting the light receiver, the high frequency radio transmission module, the level conversion module M2, the low frequency radio module W2, the double-ring antenna and power supply in water surfacefloating beacon; through the optical cable connecting units in said beacon to the bionic machinery fish, respectively sending video-digital signal to ground control table by radio modules of high frequency and low frequency.

Description

technical field [0001] The invention relates to a water surface information relay system, in particular to an information transmission system between an underwater bionic robotic fish and a ground console. Background technique [0002] The bionic robot fish is a bionic that imitates fish. From 1994 when MIT successfully developed Robotuna, the world's first real bionic robot fish, to the current domestic and foreign research institutions are constantly developing new types of artificial robot fish, human beings are constantly pursuing and exploring high-performance shipping tools. At present, under the promotion of bionics, material science, control science and other disciplines, the research of bionic robot fish has become a research hotspot in the field of robotics. [0003] At present, many bionic robot fish focus on the research of swimming mechanism, without information transmission with the outside world, the robot fish moves according to the preset setting or a certa...
