Modular Glove Machine Control System Design

With the improvement of mechanical and electrical integration of the glove machine level,some of the glove machine control subsystem is the traditional mechanical type is converted intomechanical and electrical combination type, electric proportion bigger and bigger, even morethan the trend of the mechanical parts．Although electric control model has the advantages ofsimple structure, flexible operation, but the traditional mechanical model has the advantages ofstable, so the two types respectively occupy a certain proportion of the market．This will be themain part of the glove machine modular design, make the existing common different subsystemsof glove machine can use the same master control program.This design first, analyze the existing glove machine different subsystem, main part of theglove machine is divided into six modules of needle selection module, flexible shaft controlmodule, yarn signal detection module, display module, interface module, keys module．The firstthree more special, there are two different control system．Needle selection module containstraditional small electromagnet control roller mechanical and new type electromagnet needleselection control system, flexible shaft control module controls the big drum has a traditionalelectromagnet type of special mechanical and electromagnetic valve control cylinder controlsystem, the module contains fixed single color yarn and double color yarn in yarn．The rest of thethree modules has not occurred against the background of different types.Therefore the glove machine control system transplant Linux system．In addition to thenecessary hardware design, still need to code the software part．The kernel part of the drive,system startup scripts, the application layer of the master control program software part ofwriting is key．Drive part will be based on Linux bus-equipment-drive structure, part of codingusing platform bus driver．Specifically write generic driver for each module, in light of differentmodels of each module to write the corresponding device file, so as to realize each module driverto control a variety of similar equipment．Still need to write the startup script/etc/init.d/rcS,through the menu options, glove machine is completed by each module start testing of theequipment．At the same time, the master control program of the application layer will be startedby the startup scripts.By the kernel part of the drive, system startup script code, that is completed through the modularization of glove machine, makes application layer glove main program andthe underlying separation, reduce glove machine mechanical structure changes bring softwaremodifications.In this paper, in order to realize the basic function of the modular glove machine controlsystem．This design is the modular thought to glove machine subsystem software compatibilitybetween the old and the new provides a good solution．Make the glove machine will no longerdue to the change of some subsystems bring about changes in the entire software system.
