Furthermore,the remote control ofthelasermarking system callbeimplemented by munication power ofthe PC/104. First,thispaper analyses thedisadvantage of thesoftwareplatform used by current control mode on real—time and multitask scheduling,discusses the advantage of the development oflasermarking control software based on embedded re{il·time way toimplement real—time controlunder linuxsystem isresearched,e tosolution by added the RTLinux ,the graphic processing used in thissystem is researched,and thegraphic processing algorithm usedinthissystem last, the concrete implementation ofthe whole software system isintroduced indetail,and the improvable aspect isgiven.
