The Research of Precision Agriculture and Virtual Systemof Agricultural Production

摘要

The virtual system of agriculture production develops through transplanting the idea andtechnique of virtual manufacturing (VM) which have been successfully used in industrial field intoagricultural production. It is a comprehensive subject which is developed on the basis of thesimulating and the modeling ,and is supported by many subjects ,such as computer graphics ,intellectual technology, virtual-practical technique, etc. Under virtual environment ,the practicalsystem of production is simulated through the use of simulating and modeling technique.A variety of abstract models and processes which form virtual system of agricultural production aresimilar to practical objects and processes in many ways such as feature ,action and function ,etc,and are correlative with practical models and process one by one . The virtual system of agriculturalproduction help people know products’ function and production’s process as well as productionsystemstate before the practical products is manufactured so that excellent tactics could be donetimely.The virtual system of agricultural production neither expends resource of material and energy norproduces any practical products basically, but whole production process from market analyzing,breed fostering , market administering to service after sale is realized substantially on computer.This text has discussed the concept, meaning ,feasibility and system structure of virtual agriculturalproduction system, and the key technique which develops virtual system of agricultural production. Itcan be found out obviously that the virtual system of agricultural production is a new technique. Itselfis developing ,but its application will change the appearance of agricultural production system.
