| Abstract: | The security and the reliability are the main problems that the network control system face.This paper design a new network control scheme to resolve the problems.It draws on the network isolation of the main monitoring station of the industrial site and the filter technology of the NDIS intermediate driver to realize the system＇s hidden protection.The results show that it not only reduce the communication burden of the industrial controller,improve the real Time Capabilities of the system,but also effectively guarantee the safety and reliability of the system. |
