Weather Information Acquisition System Based on SIM Card 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 E-Lins 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.
