The invention discloses a full-automatic lifting plate control system which is reasonable to design, is convenient to install and use and has low cost. The full-automatic lifting plate control system is provided with a master control controller module, wherein the master control controller module receives data information and processes data and commands; the master control controller module is respectively electrically connected with a motion control module, an intelligent sensing network for collecting and feeding back data information and a controller local area network communication port; the controller local area network communication port is electrically connected with a lumping control system; and the power supply of each system adopts an isolated power supply mode. The full-automatic lifting plate control system is an intelligent and efficient dedicated control system for the lifting plate of a flat knitting machine, so that the stress is even when a cut piece is lifted, yarn is saved, the control precision is high, and the full-automatic lifting plate control system is accurate to position. The reliability of the whole lifting system is improved, and the production force and the production quality are improved.
