The Research Of Yangling Fertilization Information Management System Based On Multi-source Heterogeneous Data

With the continuous further development of agricultural informatization,meanwhile, in order to make the yangling national agricultural high-tech industries demonstration zone become the important part of the agricultural teaching, scientific research, production, service and the industrialization of agriculture, so it is particularly imaportant that is using remote sensing platform quickly get more technology research precision agriculture in arid spread to our country construction about agricultural information.Yangling demonstration zone at present already had some similar individual information system, part of the information system also has the corresponding retrieval module, but there are single retrieval data sources, without achieve multiple heterogeneous data retrieval and communication, and lack of data of thematic.Aimed at this situation, through combined with remote sensing platform in collaborative projects more ground sensor with multi-platform remote sensing data from crop fertilization diagnosis technology demand, need to build a kind of yangling demonstration zone for multi-source heterogeneous data integration and information management system to solve the above problem.This article from the integration of multi-source heterogeneous data and cucumber in two dimensions of information management research, specific research work is as follows:(1) in yangling demonstration zone bearing fruit almond shaped, rubbing valley, remit three core test area as the main information collection area, according to the data basis of auxiliary decision-making platform model base demand analysis three experimental zone of the agricultural production management demand characteristics, roles, permissions, and personnel requirements, complete information of the database design and build water.(2) By three core test area wireless sensor network based data, ground, field trials and portable devices to collect data, crop and soil data, remote sensing image data of remote sensing inversion data from the different data platform, such as reasonable classification;For ground sensor network data, text data, remote sensing image data, and so on the data characteristics of multi-source heterogeneous data is analyzed, at the same time refer to relevant standards and specifications, and formulate a set of suitable for three experimental zone, fertilization in precision agriculture decision-making management data in support of the specification of data collection and sharing.(3) Through the normalized processing of multi-source heterogeneous data of text data, ground sensor network data, remote sensing images that should be respectively by essentially SSIS ETL tool, Web Service and metadata- file server multiple integration methods,these data would be integrated into the basis of information database to complete the three core experimental zone of the main crop cultivation of wheat, corn, apple on cucumber in auxiliary decision system of data integration and data management.(4) According to the demand characteristics of multi-source heterogeneous data, database management,roles and permissions, we deside to use C/S model designed and developed fertilization information management system based on multi-source heterogeneous data.
