Based on the XYZ06 surface remote sensing weather station,an automatic meteorological data acquisition and processing system is developed by means of virtual instrument technology,in which the acquisition,processing,displaying,storage and transmission of temperature and humidity data can be conducted.Inserting the date acquisition card(ACL-8216) into the terminal computer of the station,communication is realized with the observation software of this station.The communication "order words" and their meaning are shown on the screen in real time.This virtual data acquisition system can be conveniently applied to teaching practice for automatic weather stations.The expenses of experiment equipment can be greatly reduced.
