Beidou satellite based augmentation system and short message function-based marine monitoring buoy

Abstract

The invention relates to a Beidou-based marine monitoring buoy and specifically relates to a Beidou satellite based augmentation system and short message function-based marine monitoring buoy which mainly comprises a buoy sensor, a data processing unit, a Beidou satellite based augmentation receiver, a Beidou short message communication module, a laser range finding radar, a triaxial accelerometer, a disk shaped outer shell, an anchoring system and a power supply system. The marine monitoring buoy disclosed in a technical solution of the invention can be used for real time monitoring of meteorology and hydrology information of marine wind directions, wind speed, temperature, humidity, air pressure, rainfall, visibility, water temperature, salinity, waves, ocean currents and the lie; the information can be sent back to a ground monitoring center according to needs, and a centimeter grade high precision positioning function can be fulfilled; a anti-collision alarm function, a theft positioning and tracking function and the like can also be fulfilled.

Description

technical field [0001] The invention belongs to the technical field of shipping and satellite navigation, and in particular relates to a marine monitoring buoy based on a Beidou satellite-based augmentation system and a short message function. Background technique [0002] Marine buoy is an automatic marine environment observation platform and an important part of the modern marine environment three-dimensional monitoring system. It has the ability to automatically, long-term, and continuously collect marine environmental data. Even in harsh environments or when other on-site monitoring methods are difficult or impossible to monitor, ocean buoys can still work effectively. Ocean buoys are important facilities to ensure the safe navigation of ships at sea, and can provide navigation services for ships at night, foggy, rainy and other adverse weather conditions. [0003] The Beidou satellite navigation system has not been widely used in marine monitoring buoys. The current Be...

Problems solved by technology

Compared with other communication methods, the information transmission rate of Beidou is low, and the existing frequency of sending short messages of Beidou and the amount of information sent in a single time obviously do not meet the actual needs

[0006] 3. Due to the influence of man-made and natural factors such as the collision of sailing ships, tides, water flow and wind waves, the buoy will deviate from the set range of motion, thereby driving the underwater anchor to move, or when the anchor chain breaks, There is a phenomenon of buoy drift

Generally, the positioning accuracy of the buoy monitoring system is required to be 5m, and the positioning accuracy of the existing buoy monitoring system cannot meet this requirement

[0007] 4. Due to the unattended working state all the year round, it is difficult to maintain marine buoys, and they are vulnerable to intentional or unintentional impact damage from external forces, and even stolen by criminals. It is urgent to strengthen the anti-collision research of marine buoys and the location tracking after being stolen
