摘要
简述了基于现场智能测控仪的分布式温室测控系统,提出了一种结合土壤温度补偿和改进遗传算法GA寻优修正参数的土壤湿度在线检测新方法;同时,进一步以土壤湿度的模糊专家控制策略为例说明了系统控制功能的实现;最后,分析了联片温室温湿度测控项目的实际应用情况,并进行了总结。
Based on local intelligent controllers, the distributed monitor and control system tor greenhouses was introduced briefly. Because of the strong coupling and non-linearity characteristic, a new method for the soil humidity on-line measurement was proposed, with the modifying parameters and compensation of the soil temperature. The modifying parameters were optimized by the improved genetic algorithms in order to enhance the self adaptability of the soil humidity on-line measurement. In addition to, the fuzzy expert technology for soil humidity real-time control was emphasized to show control strategy realization. Finally, the monitor and control project applying in practice for temperature and humidity of the united greenhouses was discussed, and the conclusions were drawn.
