Application background



Marine meteorological monitoring system is a new type of Marine meteorological monitoring equipment developed rapidly with the development of science and technology and the need of Marine meteorological monitoring and forecasting. Improving the capability of coastal meteorological observation will provide an important basis for the accurate monitoring and prediction of disastrous weather at sea, especially the track and intensity of tropical cyclones, as well as the prediction of strong winds, fog and strong convection at sea and relevant scientific research.


The Marine meteorological monitoring system has realized three-dimensional monitoring of Marine meteorology, all-weather monitoring of Marine meteorology and automatic monitoring of unattended Marine meteorology. The three-dimensional ocean monitoring system can be used to obtain all kinds of Marine information in real time, so as to link up and give play to the role of Marine information resources in economic and social development to the greatest extent, so as to improve the capacity of Marine informatization and meet the needs of the rapid development of Marine economy.


Marine meteorological monitoring systems are generally divided into two parts: water and water. The water part is equipped with a variety of meteorological elements and sensors to measure the wind speed, wind direction, air temperature, air pressure, temperature and other meteorological elements respectively. The underwater part has a variety of hydrologic elements sensors, which respectively measure the ocean hydrologic elements such as wave, ocean current, tide level, sea temperature and salinity.




Scheme structure


To (Marine meteorological terminal acquisition equipment) : use serial port rs232/485 connection mode
On (Background server) : the module establishes TCP channel with the main station based on 4G/5G wireless network
The main function of the module: serial port application
 



System overview


The Marine meteorological monitoring system is composed of a monitoring and monitoring central station and a number of Marine meteorological monitoring buoys distributed in different locations as sub-stations. The sensor acquisition equipment in the monitoring buoy collects and analyzes the Marine meteorological indicators, and is connected with the GPRRS/4G/5G wireless transmission equipment. The data is transmitted to the monitoring center through the wireless network in real time. The monitoring center conducts unified processing and analysis of the data of each sub-station and takes corresponding countermeasures.


Front-end: detection, analysis and collection of indicators mainly rely on the corresponding professional instruments such as the Marine meteorological information acquisition terminal, and the terminal communication interface is connected with the GPRS/4G/5G wireless equipment.


Communication: the strong corrosion resistance, high specification and industrial level anti-interference characteristics of the airland wireless module, as well as its low power consumption and strong stability, can ensure that DTU can realize 24-hour real-time communication with the data of the environmental protection monitoring center under the application of ocean scene.


Background: the Marine meteorological monitoring center unifies and analyzes the information and status of all DTU in the front end through the Internet, and then takes corresponding measures.
