Computer Control Pattern of Separate Concentrated Feed Additive Compound System for Large Middle Feed Plant

Based on the analysis of characteristics of three separated systems of feed additive,pre compound system and feed compound system, a concentrated shaped micro computer control system with STD total bus was used to control feed compound system. The multi task and seperate concentrated software diagram was used in the control system. CPU will sychronously separate concentrated work by interupting, timing and cycling, if the event is random or influences the system accuracy directly, or CPU will discrectly work by asynchronously inquiring and sub programe nexting. This article also put forword the hybrid timing control with software interuption INT 48H and error self learning of computer system, which improves the system accuracy, reduces equipment investment and modernizes production management.
