摘 要：我国是农业大国, 温室种植在农业生产中占有越来越重要的地位，传统的温室大棚种植基本依靠人工操作，既耗人力又达不到理想的效果。为了提高农产品的产量、质量及附加值，迫切需要研制智能温室大棚。本文介绍智能大棚系统设计与实现课题的子课题“无线传感器网络设计”，以RS-485总线构建的传感器网络为基础，采集目标监测区域的温度、湿度、光强度等与农作物生长密切相关的数据，通过测控终端将数据传递到网络服务器，供相关人员对温室大棚进行远程监控和管理。终端接受来自服务器的指令，启动通风降温、加水、遮阳补光等调控设备。本设计硬件主要使用STM32F03单片机和ENC28J60网络接口芯片，软件使用开源的uIP1。0嵌入式TCP/IP协议栈，以TCP客户端身份与服务器建立连接并收发数据包。本文介绍了测控终端的软硬件设计思想及设计过程。91983

Abstract： Our country is agricultural country, greenhouse planting occupies more and more important position in agricultural production, the traditional greenhouses planting already relying on manual operation, consume manpower  more and more but can not  reach the ideal effect。 In order to improve the production, quality and added value of agricultural products, we urgently need to develop a smart greenhouse。 In this paper,introducing the intelligent greenhouse system design and implementation of the project of the wireless sensor network design, build an RS - 485 bus, on the basis of the sensor network collects target monitoring area, such as temperature, humidity, light intensity and crop growth is closely related to the data, through the measurement and control terminals to pass data to the web server, provide for the relevant personnel for remote monitoring and management of greenhouses。 The terminal accepts instructions from the server, and starting ventilation cooling , adding water and shading the light。 The design of the hardware is mainly use STM32F03 single-chip computer and network interface chip ENC28J60, software using open source  uIP1。0 embedded TCP/IP protocol stack, as a TCP client and server to establish connections and send and receive packets。 This paper introduces the design thought and design process of the software and hardware design of the measuring terminal。源G于J优L尔V论N文M网WwW.youeRw.com 原文+QQ75201`8766
