對西瓜大棚溫度環境的現狀進行分析,針對目前大棚中應用溫度系統的問題,并且結合宿遷當地西瓜大棚的特點需求,文章目的是研究設計控制精確、操作簡單且成本較低的大棚溫度控制系

摘要作者對宿遷當地的西瓜大棚的溫度控制現狀進行了調查,發現當地的西瓜大棚雖然有使用溫度控制方法,但其方法都需要人工去控制,操作起來比較麻煩。所以,設計一個操作簡單并且能夠實現溫度自動控制的系統就很有必要。35839
該文主要是對西瓜大棚溫度環境的現狀進行分析,針對目前大棚中應用溫度系統的問題,并且結合宿遷當地西瓜大棚的特點需求,文章目的是研究設計控制精確、操作簡單且成本較低的大棚溫度控制系統。通過使用STC89C52單片機作為主控制器、NTC熱敏電阻傳感器作為溫度信息采集原件等構成溫度控制系統整體結構,實現對大棚溫度的檢測與控制從而提升大棚內西瓜的產量。該設計系統具有成本低,結構簡單、操作方便等特點。
該設計系統主要包括以下幾個模塊:傳感器模塊、CPU模塊、顯示器模塊、按鍵模塊、繼電器模塊、數模轉換模塊和溫度調節模塊。通過這幾個模塊相互聯系工作從而實現對西瓜大棚內溫度環境進行檢測與控制。
經過試驗,檢測出了該設計系統基本能夠實現對當地西瓜大棚內的溫度進行控制。

Abstract The author made an investigation on the present conditions of temperature in watermelon greenhouse in Suqian, although the local watermelon greenhouses are using temperature control devices, but they still need manual control and it is inconvenient. So, it is necessary to design a control system which is easy to operate and could realize temperature auto-control.

This paper mainly analyzes the temperature environment of the watermelon greenhouse. Focusing on the present issue of applying the temperature system in greenhouses and combining the features and demands of watermelon greenhouses in Suqian, this paper aims to study and design an accurate-controlled, simple-operated and low cost temperature control system for greenhouses. By using STC89C52 micro-controller as the main controller and using NTC thermistor sensor as the temperature information acquisition of the original constitution of temperature control the overall structure of the system, an overall structure of temperature control system is formed to realize the detection and control of the greenhouses and thus to improve the production of watermelon greenhouses. The design system is low cost, simple-structured and easy-operated.
This system consists of the following modules: the sensor module, the CPU module, the display module, the key module, the analog-digital conversion module and the temperature control module. These modules work together to realize the detection and control of temperature environment in watermelon greenhouses.
Through experiments, this design realizes its basic temperature control in watermelon greenhouses.
