物联网环境下的温室大棚监控系统的设计

物联网环境下的温室大棚监控系统的设计(论文12000字)
摘要：为了满足现代信息化、自动化的农业温室大棚需求，本课题设计由上位机和下位组成的温室大棚远程监控、操作系统。由单片机MSP430为核心、温湿度传感器DHT11、无线通信模块nRF24L01组成的下位机负责采集和上传温室大棚内的环境数据，上位机（PC）接收、显示下位机传输的数据并由用户进行操作。上位机软件开发环境使用的是LABVIEW，编写的软件能够在显示屏上显示该时间节点的温湿度测量数据，可以即时手动调控温室大棚内的环境，也可以自动设定温湿度限制，在较长时间范围内由系统自动调控。

The Internet of things environment of greenhouse monitoring system
Abstract: In order to meet the demand of modern informatization  and automation of agricultural greenhouses, this topic design composed of upper machine and lower greenhouses remote monitoring,and the operating system. Consists of microprocessor MSP430 as the core, temperature and humidity sensor DHT11, wireless communication module nRF24L01 lower machine is responsible for the collection and uploading of greenhouses within the environmental data, the upper machine (PC) receive a machine transmission of data, display and operated by the user. PC software development environment using the LABVIEW, writing software can be displayed on the screen of the measured data of temperature and humidity, time node can regulate and control the environment inside the greenhouses, instant manual also can automatically set temperature and humidity limits, within a long time by the system automatic control.
Keywords:MSP430 single chip microcomputer, DHT11 temperature and humidity sensors, nRF24L01 communication module and Labview
