The Design And Implementation Of Miniature Ocean Buoy

In recent decades,the trend of global ocean observation has changed from the original discontinuous ship-based or shore-based survey to the current continuous fixed-point real-time observation.Developed countries are now observing the ocean through the development of advanced technologies and equipment and the use of multi-method fusion.Marine buoys are a newly developed new monitoring technology,which is gradually valued by many coastal countries and vigorously developed.It is an important technical means for offshore access to marine information and has an important role in marine development.Due to the complex environmental conditions in the water area of 100 m from the coastline in the near shallow sea area,large ships cannot operate,so it is necessary to design a miniature buoy as an alternative device.This article designs a cost-effective micro-buoy with a piston-type mechanical structure,which can work continuously for a long time without interruption.It is also used as a development platform for secondary development.This article first introduces the domestic and international research status and development trends of marine buoys,and then gives the overall design of the buoy according to the needs,including the structure design of the buoy,the realization of the remote control function,the selection of the single chip microcomputer and the design of the power supply scheme The communication module used by the buoy is the lora module,which has a networking function,and can build a monitoring network with unmanned ships and other offshore equipment.After that,the hardware and software parts of the system are introduced in detail.It introduces the STM32 series processors used in the system,and also introduces the circuits and interfaces of various hardware parts.In addition,the software development of the system is introduced.The software system is divided according to the application layer,real-time operating system and driver layer,and modular development is carried out.Then,the driver of each module is introduced.The focus is on the use of double closed-loop PID control algorithm to control the motor.Finally,an experimental test is carried out on the expected target of the buoy,and the test results are given.After analyzing the test results,it can be verified that the design reaches the expected target.
