【摘要】：在江苏东台地区,因其沙性土壤的独特地理优势,特别适合种植西瓜,这让西瓜成为当地的特产。尽管这些年来,我国智能温室的发展有了长足的进步,东台西瓜种植也引进了智能温室。但是,智能温室的成本过高,大部分小户瓜农还是采用传统的种植方法,不仅辛苦而且效率偏低。为了提高当地小户瓜农的生产效率,减轻生产负担,本文设计了一个用来实时监测温室内部环境的监测系统,并设计了远程登录功能,实现了温室种植自动化管理。本文首先对江苏东台的西瓜种植情况进行分析,并根据西瓜种植的要求进行总体设计。接着分别对系统的采集终端和监测基站,进行硬件电路设计。然后根据电路进行了系统的软件实现。为了减少采集终端的功耗,设计了一种考虑剩余电量的星型组网方式,选取电量最多的采集终端作为中间节点,负责转发接收节点的指令,并将数据传给基站。基站通过RS485总线,将接收到的数据传给上位机。最后利用LabVIEW设计了系统的上位机,实现了温室温度、湿度和光照度的实时显示,并利用其WEB功能,实现系统远程登录的要求。最终实验结果表明,本文设计的监测系统,可以有效的监测温室内部的环境,提高生产效率,并且可以减少人工成本,达到了设计要求。
[Abstract]:In the Dongtai area of Jiangsu Province, watermelon is particularly suitable for growing watermelon because of its unique geographical advantage in sandy soil, which makes watermelon a local specialty. Although the development of intelligent greenhouses in China has made great progress in recent years, Dongtai watermelon planting has also introduced intelligent greenhouses. However, the cost of smart greenhouses is too high. Most small farmers still use traditional planting methods, which are not only hard but also inefficient. In order to improve the production efficiency of local small farmers, In order to lighten the production burden, a monitoring system is designed to monitor the inner environment of greenhouse in real time, and the remote login function is designed to realize the automatic management of greenhouse planting. Firstly, this paper analyzes the planting situation of watermelon in Dongtai, Jiangsu Province. According to the requirements of watermelon planting, the overall design is carried out. Then the hardware circuit is designed for the acquisition terminal and the monitoring base station of the system, respectively. Then, the software implementation of the system is carried out according to the circuit. In order to reduce the power consumption of the acquisition terminal, In this paper, a star network is designed, which considers the residual quantity of electricity. The acquisition terminal with the most electricity is selected as the intermediate node, which is responsible for forwarding the instructions of the receiving node and transmitting the data to the base station. The base station passes the data through the RS485 bus. Finally, the upper computer of the system is designed by using LabVIEW. The real-time display of greenhouse temperature, humidity and illuminance is realized, and the requirement of remote login of the system is realized by using its WEB function. Finally, the experiment results show that, The monitoring system designed in this paper can effectively monitor the environment inside the greenhouse, improve the production efficiency, and can reduce the labor cost and meet the design requirements.
