Based On The Powerpc The Fsc823 Large Plotter Control System Design And Realization

The graph plotter is an in common use equipment to output graph, and it can conserve pattern on plot paper which make by computer. In the CAD system, pattern picture which make by design and put the code system, and the row material which make by the row material system, all needing 1:1 proportion drawing in plot paper, for usage of cutting out working procedure. Therefore, The graph plotter of wide breadth is the important output equipment of the clothing system significantly.The large graph plotter that current home clothing CAD uses the majority is the import equipment, the function is better, but the price is expensive, and the many of them are appropriative. In the domestic, there is the few factory to produce the large graph plotter in appropriation in CAD clothing machine. Traditional graph plotter in adoption is SCM control system, has no graph show function, need to link with computer, each graph plotter need a set of homologous softwares, passing the computer the command would be transmited to the graph plotter, still needing the computer to show an appearance for drawing sketch, machine can't be independent of the computer in dependence painting.For making graph plotter to escape from the computer independence painting, this task adopt linux embed operation system to empolder clothing graph plotter, it is a kind of innovation from the empoldering means. Make use of the trait and predominance of linux embed system, can not only realize above functions, but also because of the graph plotter has the USB and net interface, can read directly the painting in the USB to paint, also can pass the net read the document in the arbitrary computer, then can read the painting documents in the mailbox to paint. Customer use it more convenient, it can satisfy more extensive customer's need. The control part of graph plotter mainly adoptions PowerPC FSC823 embed system to control two electrical equipments and draw planar graph. Practice proving, use the embed system to empolder graph plotter contain excellences, such as hardware electrocircuit design simple, function abundance, control more accurate etc.
