“…The field working data can be remotely recalled and stored directly in the corresponding database, greatly improving the efficiency of data collection, the analysis and application; when the mechanical failure, the mechanical users can also make use of the computer techniques to analysis and diagnostic ,or to take targeting processing procedures of precision agriculture, which is basing on GPS, GIS, RS Technology for urging on the agricultural production to be changed more scientific and refined.
