摘要
为准确研究环境因素对农作物的生长产生的影响,设计了一种可以自动调节气室CO2浓度的检测控制系统。该系统采用12846液晶实时显示数据,根据人工设定气体含量参数,自动控制CO2发生器维持气室的气体含量。研究结果表明,该系统可对气室内氧气、二氧化碳和发生器内压力数据进行采集与控制,可实现内部存储、U盘读取和直接与PC机通信,以及在PC机上显示、存储数据等功能。
In order to accurately research environment factors on the effects of crop growth,a kind of the detection and control system of gas chamber automatically adjusting the CO2 concentration was designed.The system can collect and control the data of oxygen,carbon dioxide in gas chamber and the pressure of the carbon dioxide generator.And the system can real-timely display gas data with a 12846 LCD.According to artificially setting gas content parameters,the system can automatic control CO2 generator of gas content to maintain the gas chamber.Results show that the system can store data and read by U-disk directly.When communicating with PC,it can display and store data in PC.
