Study On Cropland Information Speediness Collection And Manage System Base On GPS And GIS

Since 20th century 1980s,information tidal wave fills the whole globe base on computer technology fiber and secondary planet communicate technology,information level become important sign which weighs a country's modernization level and synthesis national power. Agriculture modernization is important compose part of socialism modernization building in our country,its essence is science technology of agriculture,which is equipping agriculture by modern times science and technology and its application,accordingly drive our country agriculture transformation form tradition agriculture to modern times agriculture. In the present age,on the one hand,we should depend modern times science technology,building firm modern times agriculture basic,strive for realizing agriculture mechanization earlier;On the other hand,we should receive challenge of the world economy age,develop new agriculture science and technology revolution,develop information agriculture,push agriculture information course.This paper aim at characteristic of age,combine a whole by GPS technology,GIS Technology,DSS Technology and sensor Technology,and apply some facets of cropland information decision-making system,the result is very good.The main research content of this paper including:(1) Develop instrument equipmentIn research course of this problem,penman and doctor qiu develop a cropland information speediness decision-making testing instrument in order to prevail cropland information. This new instrument have test-speed-rapid,test-precision-high,real -time-test,and can test orientation-information compare to tradition instrument. It can problem of orientation difficulty when prevail cropland information at present.(2) Experiment analysis of SWR soil moisture sensorBecause of cropland information excessive,can't experiment everyone,penmanprocess soil containing water or moisture data experiment to vegetable terras cropland and gravel,prevailed experiment data,and draw experiment curve drawing of differ soil. The results turned out to be:1) SWR soil moisture sensor have higher precision and stronger practical value .2) Different soil and different soil depth,soil containing water or moisture data is disciplinarian transform. Meanwhile,Using this apparatus measured soil containing water data from plane and section,and using software Arc view insert value analyzed by distance inverse ratio measure,the result is very good.(3) The study of GPS orientation experimentIn this paper,penman do some experiments by GPS310 and GPS315.The main experiment including:GPS310 odd spot experiment > GPS315 relative orientation experiment GPS3 10 area experiment. Simultaneity,this paper advanced a means of real time calculate area in order to calculate area effectively,it have some utility value.(4) The project of cropland information decision-making systemThe core of this paper is develop and design of cropland information decision-making system. The whole system base on theory of charter one to charter six,inherited basic structure of tradition information system,appended GPS GIS DSS especial function. It can the whole system function more perfect,designated cropland manage aspect henceforth effectively.
