Abstract:
A design method of serial communieation protoeol was developed between PC and lower computer torealize graphies processing control in self-developed laser miero processing system. Through the image proeess.ing, irregular pieture was changed into binary image formed by m rows and n columns. Each row consists ofmany segments with alterate need and need nol machined. All the rows were selting value. A frame, trans.ferred to lower controller using serial communieation, was composed of start text (STX ), bytes, funetioneode, data, cheek-sum and end text ( ETX ). Before exeeution, each reeeived frame would be checked. Theresult of review and execution need feedback to PC. The feedback frame was the evidenee determined if theframe needs to be resent. The data frame feedback method ean improve the reliability of eommunieation.
