Abstract: The systematic model tool Petri net which directed against numerically controlled machine tools to renew and keep in the present situation is introduced into system research of the intelligent network reliability. In the foundation of collateral and dispersed conduct among intelligence network itself, reliability database and operator, the system model are set up, and the program code are be automatic produce. In the meantime, the XML is combined to realize between diverse database to enjoy something together. The imitative test is test and verify this method to be feasible in experiment balcony.
