Agricultural Drought Data Acquisition and Transmission System Based on Internet of Things

Abstract

The real-time acquisition and transmission system of agricultural drought data is researched. With the real time acquisition and analysis of agricultural drought data, it can effectively and accurately predict and analyze the agricultural drought data and provide scientific decision-making of water supply and drainage engineering. It has great significance in increasing agricultural production and to promoting agricultural production. Based on Internet of things technology, the networking sensing layer is distributed in the agricultural infrastructures, real-time data acquisition is realized, the network transmission layer is used to transmit the agricultural drought data, the scientific decision-making of water supply and drainage is realized in the decision layer based on expert system, the scientific decision-making of water supply and drainage is realized. The design scheme of agricultural drought data acquisition and transmission system is proposed based on Internet of Things. The infrared detector 512X10 is designed, the amplification of the input matching circuit are used in circuit design with low noise, for filtering and de-noising processing is realized in the FPGA for the agricultural drought data acquisition. Simulation result shows that the system acquisition and transmission performance is perfect, and it has prospective application value in the agricultural drought data acquisition and analysis.
