The invention discloses a fully-mechanized circular knitting
machine control system which comprises a man-
machine interaction unit, a real-
time control unit and a mechanism executing unit, wherein the man-
machine interaction unit is connected with the real-
time control unit by adopting a parallel
bus; the real-
time control unit and the mechanism executing unit respectively realize data communication of density motor regulation control and control of various kinds of air valves by adopting a multi-path RS 485
bus and a multi-node
CAN bus; the man-machine interaction unit is used for displaying state information of the fully-mechanized circular knitting
machine control system, editing, storing and analyzing pattern files, editing
system control parameters, and testing actions of all functional parts; the real-time
control unit is used for reading process action information in a
data conversion unit through the parallel
bus, and storing the process action information in an external
expanded memory of the real-time
control unit; and the mechanism executing unit is used for controlling the action of a needle selector, density regulation action and actions of various kinds of air valves. The fully-mechanized circular knitting
machine control system has the advantages of being large in pattern weaving range, being high in replacement speed, shortening the design period of products, being high in weaving speed, increasing the production efficiency and ensuring the reliability of system production.
