摘 要智能农业是随着 Internet 的普及使用而发展起来的一门技术，他是集新兴的互联网、移动互联、云计算和物联网技术为一体，依托在现场的各种传感器节点（空气温度传感器、空气湿度传感器、光照传感器，土壤湿度传感器、二氧化碳传感器）和无线网络共同实现农业生产过程中的各阶段的智能感知、预警、收集、分析、决策，为农业生产提供可视化的管理和智能化的决策。MQTT（Message Queuing Telemetry Transport，消息队列遥测传输协议），是一种基于发布/订阅（publish/subscribe）模式的轻量级协议，该协议构建于TCP/IP 协议之上，MQTT 最大优点在于，可以以极少的代码和有限的带宽，为连接远程设备提供实时可靠的消息服务。作为一种低开销、低带宽占用的即时通讯协议，使其在物联网、小型设备、移动应用等方面有较广泛的应用。可以完整的体现出我对于知识的综合运用和理解。本系统通过前端开发和后端开发的结合，以及充分利用 JAVA 这个主流的脚本语言，实现了一个功能健全的智能农业系统关键字： 智能农业 ；物联网 ；传感器 ；MQTT ABSTRACTIntelligent agriculture is a technology developed with the popularity of Internet.It is a integration of emerging Internet, mobile interconnection, cloud computing and the Internet of things technology, relying on various sensor nodes in the field (air temperature sensor, air humidity sensor, light sensor, soil humidity sensor, Carbon dioxide sensor) and wireless network can realize intelligent perception, early warning, collection, analysis and decision-making in all stages of agricultural production, and provide visual management and intelligent decision-making for agricultural production.The MQTT (Message Queuing Telemetry Transport) is a lightweight protocol based on publish/subscribe mode, which is built on the TCP/IP protocol. The greatest advantage of MQTT is that it can provide real-time and reliable message service for connecting remote devices with very little code and limited bandwidth.As a low-cost and low-bandwidth instant communication protocol, ...
