基于FPGA的土壤数据采集分析决策系统

A Soil Date Collecting, Analyzing and Decision-making System Based on FPGA

摘要:

为了改善当前土壤施肥及土壤数据管理的盲目性和随意性,提出了一种基于现场可编程门阵列(FPGA)的土壤数据采集分析决策系统;系统用FPGA搭建了土壤数据采集模块,采集了温湿度、酸碱度、常量元素含量和中微量元素含量等土壤信息,通过GPRS将采集到的数据传输给上位机;上位机以专家信息为参考,结合测土施肥技术、数据库技术和.NET技术,完成数据库、模型库和知识库的建立,并最终给出适宜种植的作物、肥力评价、施肥方案等决策结果;试验测试结果表明,该系统可以为种植农作物提供有效方案,在农业生产中有一定的应用前景。

Abstract:

In order to improve the blindness and randomness of current soil fertilization and soil data management, a soil data collecting, analyzing decision-making system based on field programmable gate array(FPGA) is proposed in this paper. This system builds the soil data collecting module on FPGA, which is designed for gathering temperature, humidity, pH, major elements and trace elements content in soil and transmitting the collected data to the host computer by GPRS. The host computer establish database, model base and knowledge base by using expert’s information and soil testing and fertilizer recommendation technology, and decision-making results will show suitable plant,evaluation of fertility and fertilization scheme. Test result show that the system can provide valid solution for crop planting and has a broad application prospect in the field of agriculture.
