Research And Development Of Main Control Unit Of The Meteorological Data Collector Based On MPU

There have close relations between Meteorology and the surevival, production activities of mankind, national defense or social and economic developmentare subject to weather detection. Already existing meteorological observation way to rely on artificial operating and reading mainly, not only efficiency is low, but also every parameter needs artificial record and gather, the work load is huge, apt to make mistakes, can't already meet the existing meteorological observation request. Meanwhile, development and application of information technology, electronic technology and computer technology, offer strong technical support for automatic meteorological observation. Under this kind of environment, the automatic meteorological observation technology of our country has got the fast development. Through the research work for many years, it is already ripe basically to observe technology. But in the research of its key equipment——the meteorological data collector, research work far lags behind the foreign developed country. The meteorological data collector is one of the main technological difficult problems of the meteorological instrument trade of our country. There are no ripe products yet at home. The supply and demand depends on the foreign import products mainly.In the face of the current situation of developing new generation data collector with high accuracy and high flexibility for our country, this thesis carries on research and structures to the main control unit of the meteorological data collector. It offers the platform for the designs of other parts of data collector. The main control unit like the microcomputer embedded in the automatic meteorological observation system, is the control and operation core of the whole gather system. The quality of its performance determines directly the kinds of the collector function and excellence of performance.
