Marine meteorological monitoring solutionsApplication background The 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 for 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 structureTo (Marine meteorological terminal acquisition equipment) : use serial port rs232/485 connection mode On (Background server): the module establishes a TCP channel with the main station based on a 4G/5G wireless network The main function of the module: serial port application System overviewThe 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 GPRS/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 air and 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.Features and advantages The equipment works with the national ocean center to match and meet the requirements of ocean monitoring application scenarios to the maximum extent possible. Ultra-low power consumption equipment helps the national ocean center to achieve ultra-long, stable, and reliable monitoring needs, among which the average power consumption of equipment is 0.09w online non-communication, and the average value of big data communication is 0.4-0.6w. It can meet the low power environment of the solar power supply. Strong resistance to salt spray corrosion adapts to extreme sea weather and the environment. High-standard industrial-grade wireless communication equipment can guarantee the stability and reliability of meteorological data. With GPRRS/4G/5G wireless communication, it is possible to set up automatic monitoring stations on any sea surface where there is a wireless signal. The equipment is easy to operate, easy to install and maintain, no need for professionals so that the site installation and debugging personnel are easy and efficient. Low cost, reduce the use of costs.
