| Abstract: | The research is carried out for the control part of radiographic inspection system in this paper.A distributed control mode based on CAN is proposed.The message framing and data link control proccedure are introduced.Moreover,the CAN interface and the corresponding communication software are accomplished.The control mode for slave units is designed by which the real time monitoring of inspection process is achieved.In addition,the possible application in future is also discussed.It is indicated through practice that the methods presented in this paper possesses the advantage of high transmission rate,strong reliability and good flexibility which make it suitable for the control of real time radiography inspection station.Meanwhile,it can also be applied to other similar situations. |
