Weather information acquisition system based on 4g industrial Router

The meteorological information acquisition system uses the real-time meteorological data to make more accurate prediction and alarm to the meteorological conditions in a certain period of time, including short-term rainfall forecast, medium-term precipitation forecast and flood early warning forecast, which is a very important link in the flood control work.

The traditional meteorological information collection is automatically completed by each meteorological observation station using meteorological acquisition equipment, and the meteorological data is transmitted to the meteorological center through DDN or telephone lines. After processing and analysis, the short-term and medium-term rainfall can be forecast, providing reliable decision support for flood prediction and flood control. The adoption of DDN can fully ensure the smooth and complete data transmission, but the disadvantage is that the monthly fee is too high; The use of PSTN telephone lines for data transmission, billing by the time, is not cheap.

A new method of transmitting meteorological information through wireless data communication is now available. Each meteorological collection point maintains real-time connection with the host station of the central station through SIM card router. The automatic observation equipment will transmit the meteorological information obtained to the host station of the meteorological center, which will process the information and form the meteorological forecast information.

The communication system based on router has the advantages of making full use of the existing network, shortening the construction period and reducing the construction cost, and has the characteristics of convenient installation, simple maintenance and strong expansion of the equipment.

The structure of meteorological acquisition system is described below

1. Meteorological information collection point: the 3G/4G/5G wireless data acquisition and transmission terminal of E-LINS is adopted, which is connected to the computer through RS232 serial port and connected to the dedicated 3G/4G/5G wireless network provided by the Meteorological Bureau by the Mobile Company. Computer operation system software and application software of meteorological information collection point. The network has no restrictions on the location, time or number of meteorological information collection points, which can be increased or decreased at any time. It can meet the needs of mountainous areas, remote areas and cross-regional access.

2. Meteorological Central Station: DDN special lines provided by Provincial Mobile, China Unicom and China Telecom are used to connect with 2G/3G/4G wireless network. Because DDN special line can provide high bandwidth, when the number of meteorological information collection points increases, the center can meet the demand without expanding capacity.

3. 2G/3G/4G wireless transmission weather station adopts the line and interface provided by mobile. All meteorological information collection points use a unified STK card. Meanwhile, the meteorological center registers all points and saves relevant data for identification and maintenance. The STK card used in the meteorological information collection point can only be used for data communication function with the meteorological information collection system. Each meteorological information collection point runs the original system software and application software, which supports the 24-hour real-time online, and realizes the 24-hour transmission of meteorological information data collected by the meteorological information collection point.
