This text chiefly introduces how to design a program to accomplish intelligence state examination system according to the original state examination system about the Y type of product of X type of aircraft. During the research process, in accordance with the examination rules of original system rigorously, we design the work flow and change the ageing mechanical switch virtually into the button on the touch screen. In addition, the standard signal which was provided with the electric circuit that composed by the electric relay before is completely replaced with the program in the original system during the examination program. Through the industry controlling machine, the improved system can accomplish state examination under all kinds starting ways of planes. The structure of new system becomes more inseparable, meanwhile the efficiency is improved and the reliability is enhanced.
