摘　　要：针对手工浇注的特点与现状,提出浇注自动化的设想,建立了浇口液位的控制模型,采用工业摄像检测浇口液位、铁液包失重间接检测浇注流量法,设计了浇注串级控制控制系统。根据浇口液位的数学模型,提出了基于组态软件、串级技术和智能仪表的自动浇注控制系统。结果表明,串级技术能有效地抑制系统中存在的扰动,通过提高主控制器的增益,可以提高系统工作频率,改善浇注品质。Aiming at the characteristics and problems of handicraft pouring in foundry,the mathematics model of objects were established and the auto-pouring cascade control system was designed,based on CCD sensor and weigh-lost weightier.The controller used configuration software,intelligence measuring appliance and cascade control was investigated,according to the mathematics mode of pouring system.The results showed that the good effects were achieved by the cascade controller and the control system has the characteristics of static accuracy,adaptability,reliability and anti-interference by rising main controller＇s variable gain.
