Design of Simulation Device for Greenhouse Control

To avoid the cases that control algorithm can`t work well after application in green-house, and then cause losses, it`s essential to test the performance of the control algorithm before putting it into practical use. To achieve this, we need a method to test the control algorithm rapidly and effectively. However, there is no such effective method to test the performance of the control algorithm in a greenhouse. With the rapid development of the IoT technology in the field of agricultural production, the method of process data modeling is proposed to help solve such problems. Based on the method of process data modeling, this paper proposes a new model which includes Z-transformation, scope control, OFF response and difference bias, and developed a greenhouse simulation test model. The experimental results show that our model can capture the changes of both temperature and humidity, and also limit the humidity within the set range. This proves that our model is effective and precise.
