基于专家系统的储粮机械通风控制系统

Intelligent Control System of Storing Mechanical Ventilation Based on the Expert System

机械通风是粮库保持粮食品质的重要手段之一。但是由于粮情变化与含水率、仓储温度以及湿度等诸多因素相关,人工通风存在很多不足之处。对专家系统的知识规则库进行研究并根据实际应用提出具体的规则设计方法,利用专家系统的人机交互方式和系统自学习方式进行知识获取和修订补充,可以对粮库进行机械通风的决策以及通风过程中控制方面起到一个高级储粮专家的作用。实践证明,这种研究方法具有广泛的应用前景。

Mechanical ventilation is one of the most important ways to keep grain＇s quality in barn, whereas artificial ventilation has many disadvantages for those factors such as ratio of water,temperature and humidity of barn involved in the changes of gain quality. The design details of rule definition based on practicality is brought forward after research of expert system＇s knowledge - rule database. Expert system will work as an advanced grain storing expert in the decision and control of storing ventilation when using expert system＇s interactive man - machine technique and self - study system technique to gain new knowledge and modify previous knowledge. It has been proved that the research means have bright application future.
