Problems solved by technology

In this implementation mode, OPC data packets will not be disassembled and protocol converted, but will be transparently transmitted directly through the gatekeeper ferry system, so the security risks carried by the original traffic will also be propagated, which greatly reduces the network gatekeeper safety efficacy

Abstract

The embodiment of the invention provides an OPC gateway system based on Linux and a data processing method, the system comprises a first host and a second host, a virtualization platform is built on the Linux system of the first host and the second host, and a Windows client operating system is installed on the virtualization platform; wherein an OPC Server proxy program runs in a Windows client operating system of the second host, and an OPC Client proxy program runs in a Windows client operating system of the first host; and the first host and the second host are both provided with Socket services. According to the embodiment of the invention, from the perspective of a virtualization technology, Windows is operated in a Linux virtualization platform, so that an OPC program developed by Window is indirectly operated in a Linux environment, and Linux-based OPC data collection and proxy are realized on the whole.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a Linux-based OPC gatekeeper system and a data processing method. Background technique [0002] In the industrial production process system, it is necessary to collect the data generated by the controller devices of various manufacturers through the OPC protocol. The OPC gatekeeper is deployed between the OPC Server and the OPC Client to proxy and transmit the OPC data, so as to This is to ensure network isolation and security protection. [0003] The OPC protocol standard is formulated by Microsoft Corporation and implemented based on Microsoft's DCOM standard. DCOM is a private standard of Microsoft, and Microsoft has not released its source code and detailed design documents, so OPC is a private protocol of Microsoft, and OPC-related development can only be carried out in the windows environment. Due to the openness and high performance of Linux, network security devices i...
