摘要
以DVP-SS-11R型PLC为蔬菜大棚温湿度控制中心,利用DOP-B07S201型触摸屏显示,设定温湿度值以及报警的上下限值,使用电子模块DVP-04PT、DVP-04AD以及温度传感器PT100和湿度传感器HM1500对蔬菜大棚的温湿度进行检测,实现对蔬菜大棚温度和湿度的控制。
The PLC is used as the control center of the system that can measure and control the temperature and humidity of the vegetable greenhouse.With the help of touching screen,users can set the required value of temperature and humidity,and also the upper-lower limit of temperature and humidity.The touching screen will give an alarm when the temperature and humidity go beyond the limit.The electronic modules DVP-04PT,DVP-04AD,temperature sensors PT100,humidity sensors HM1500,are used to examine temperature and humidity respectively.
