基于物联网技术的农业智能化培养控制系统的开发   Agricultural intelligent cultivate control system based on Internet of Things technology development
摘  要
最近几年社会上在农业领域中广泛提出了智能农业的口号,认为智能农业是现代农业的重要标志和高级阶段,在农业产业链的各个关键环节,通过信息、知识和现代高新技术的高度融合,用信息流调控农业生产和经营活动的全过程,由于以上原因,此次毕业设计就研发设计了一套基于ZigBee网络的农业数据采集系统。
这套系统主要采用TI德州仪器公司生产的基于标准协议IEEE 802.15.4的2.4GHz的CC2530片上系统,配备有温度、湿度、光照度三种传感器,以网关、协调器、路由器和终端的形式组建网络,外网以SIM900为主的GSM短信实现,此次设计虽然没有涉及上位机软件的开发,但是在协调器上预留了串口转USB接口链接PC机。
这套系统能够自动完成环境监测、数据传输、参数显示以及远程查询等工作。通过传感器采集、网络传输,将数据汇集到协调器上,以3种方式显示或查询。第一种方式是在协调器上的LCD显示屏上显示数据;第二种方式是通过串口发送至PC机;第三种方式是将协调器链接到GSM模块,等待用户发送短信验证码查询数据。

Abstract
Recently years, in the field of agriculture , the slogan of intelligent agriculture is widely proposed , People think intelligent agriculture is an important symbol and advanced stage of modern agriculture . Intelligent agriculture is that in the agriculture industry chain of each key link , through the fusion of information , knowledge and the modern new high-tech ,using information flow to control agricultural production and operation activities in the whole process. The graduation design reserachs a set of agriculture data acquisition system,which is based on the ZigBee network.
The system mainly using TI company Texas instruments’s 2.4 GHz CC2530 chip system, which production is based on the standard agreement of the IEEE 802.15.4 , and equipped with three kinds of sensors ,namely temperature, humidity and light. The CC2530 chip system build a network in the form of gateway, coordinator, routers and the terminal .In addition ,the outer net’s GSM message implementation is mainly on SIM900, Although this design is not involved in the development of PC software , on the coordinator device of turning serial to USB interface is reserved to link PCS.
The system can automatically complete the work about environmental monitoring, data transmission, parameter display and remote inquiry . Through the sensors collecting and network transmission , collecting the data to the coordinator, with three ways to display or inquiry. The first way is to display data on the LCD screen of coordinator ; The second way is sent the data to the PC by serial; And the finally way is to link the coordinator to GSM module, waiting for the user to send a text message verification code to inquire the data.
