1、 I 智能农业监测系统设计 摘 要 在科技高速发展的今天，传统的农业生产方式已经渐渐跟不上快速发展 的经济需求。因此人们利用先进现代化科技创造了温室大棚、作物杂交、无 土栽培、太空育种等众多现代化农业种植技术。但这些先进的农业生产方式 大多数都是投入成本高，操作技术复杂，对操作人员的素质要求很高，从而 难以使普通的农民用户运用上这些先进农业生产技术。 本课题意在设计一款适合普通农民大众使用智能农业监测系统，本智能 农业监测系统主要应用于温室大棚农业生产。本系统主要基于嵌入式系统设 计，采用 ARM920T 架构的 S3C2440A 芯片作为主控芯片，用 DHT11(温湿度监 测)、MH-410
2、D5(二氧化碳传感器)、MQ-2(烟雾监测传感器)、TSL2561(光照强 度传感器)等传感器作为系统的环境监测模块， 用 RS485 串口作为系统远程通 信接口，用 P35 触摸屏作为系统人机交互窗口。本系统的最终实现效果为能 够对温室内温湿度、光照强度、CO浓度实时监测，且能将监测数据在 P35 屏上以直观的形式显示出来，当其中的某项指标达到预设值时系统能立马做 出信息反馈，调动其他设备及时对温室环境做出调控。最后系统还能够进行 远程控制和检测温室内烟雾与可燃性气体的浓度，做到遇火灾报警功能。 整个系统具有简单易用、成本低廉、智能化程度高、可靠性高等特点， 非常适合普通农民大众使用。 关键
