【摘要】 为实现农业温室大棚的智能感知与远程控制,设计了基于物联网的智能化温室,研究了物联网在农业温室大棚的应用。首先,阐述了基于物联网的智能化温室工程整体方案,包括基础结构的设计、覆盖材料的选择、通风系统的设计以及保温系统的设计等,详细设计了智能化温室的结构。其次,对物联网的层次架构进行设计,为了兼容各类终端,在物联网标准的3层模式上附加了终端接入层,共计4层结构:终端接入层、系统应用层、中间件及感知层。然后,阐述了系统功能设计,在6大功能模块中着重阐述其中的数据采集功能以及数据分析预测功能,重点对涉及到的关键技术,即物联网关的设计、服务器通讯协议的实现及逻辑控制模式进行阐述。结合温室数据量以及传输模式,对主要命令字的代码及含义、消息头与消息体进行设计,对主要字段的定义名称、字段宽度及字段数据类型、含义等进行设计。更多还原

【Abstract】 This paper studies the Internet of things application of intellisense and remote control in agricultural greenhouses. Firstly it expounds the intelligent greenhouse based on Internet of things as a whole,including infrastructure design,cover material,ventilation system and the design of the thermal insulation system,etc. Then it designs general construction and hierarchy construction,divides hierarchy of system function construction. It establishes the hierarchy architecture of agricultural greenhouses and increases the terminal access layer to compatible with all kinds of terminal. Then the system functions and the implementation flow chart were described,and the function of data acquisition and prediction function are emphasized. In the realization of the key technologies the command code and the meaning of the word are designed.更多还原
