基于FPGA的智慧果园土壤环境信息采集系统

FPGA-based Intelligent Orchard Soil Environmental Information Acquisition System

针对精准智慧果园需要完整的智慧果园测控管理系统来促进中国智慧化果园的发展,提出了一种基于FPGA的智慧果园土壤采集系统的设计方案。系统总体设计主要包括土壤信息采集、数据传输、数据存储、数据处理等几个方面,硬件部分包含各类器件的选型,软件部分包含所用的语言、开发软件、AD转换和仿真。首先,以FPGA为控制核心,简化电路的设计,充分利用其存储功能;其次,采用传感器采集土壤湿度信息,并利用AD转换器将模拟信号转化为数字信号,将结果显示在LCD液晶屏上,再将采集到的数据传输给主模块;最后,通过判断实现灌溉,该采集系统符合现代智慧果园的发展趋势。

A complete smart orchard monitoring and control system is needed to promote the development of intelligent orchards in China.A design scheme based on FPGA for a smart orchard soil collection system is proposed,which mainly includes soil information collection,data transmission,data storage,data processing,and other aspects.The overall design of the system is presented,including the selection of various devices for the hardware part and the language,development software,AD conversion,and simulation for the software part.To simplify the circuit design,FPGA is utilized as the control core to make full useof its storage function,and sensors is utilized to collect soil moisture information.The AD converter converts the analog signal into a digital signal and displays the result on an LCD screen,the collected data is then transmitted to the main module and irrigation is implemented through judgment.In summary,the collection system conforms to the development trend of modern smart orchard.
