Design of Frequency Converting System for Trawling Winch
摘要
Abstract
Based on the operational characteristics of trawling winch ,the controlling scheme of the frequency converting system was designed. The scheme kept the trawl winch constant tension by PLC and conveyer control AC motor which used the trawling tension as control object. The variable frequency speed-adjusting system was introduced with the control scheme and constitution of the system,and the hardware circuit,software were designed as well. The results showed that the control system had advantages of high running accuracy and good stability ,and could meet the safe, reliable operation for trawl winch under special environmental conditions.关键词
