一、概述在冶金、水泥、化工、食品等行业的产品中,有很多产品都是由多种原料以一定的比例进行综合加工而制成,产品质量的好坏在很大程度上取决于这些原料配比的精度。配料不准,就会出废品,并由此引起一系列的恶性循环,产生综合性的不良效果。自动配料控制是当前国内外的重要课题之一。综观国内目前的配料状况,大都是人工操作。由于生产现场条件恶劣,测试手段落后,并且带有随机性,工人的劳动强度大,所以配料精度很难保证。这种落后的工作方法,不仅与当前企业大生产的规模不相适应, First, an overview In the metallurgical, cement, chemical, food and other industries products, many products are made from a variety of raw materials to a certain percentage of the overall processing and made, the quality of the product depends largely on these Raw material ratio accuracy. Ingredients are not allowed, it will be a waste, and thus cause a series of vicious circle, resulting in a comprehensive adverse effects. Automatic ingredient control is one of the important topics at home and abroad. Looking at the current status of the domestic ingredients, mostly manual operation. Due to poor production site conditions, testing methods behind, and with randomness, the labor intensity of workers, so the accuracy of ingredients is difficult to guarantee. This backward working method not only does not fit the current scale of the large-scale production of enterprises,
