Technology for realizing data acquisition and forwarding based on industrial gatekeeper under 2 + 1 architecture

Abstract

The invention discloses a technology for realizing data acquisition and forwarding based on an industrial gatekeeper under a 2 + 1 architecture, which comprises an inner end machine, an outer end machine and a transmission medium, the inner end machine and the outer end machine are connected through the transmission medium, the inner end machine and the outer end machine are also connected with anarbitration machine through special hardware and a special protocol, the arbitration machine is isolated from an external TCP / IP protocol module, the transmission medium is one or more of a wired channel, a carrier channel, a microwave channel or an optical fiber channel, and the inner end machine and the outer end machine are provided with communication interfaces. The inner end machine and theouter end machine are connected through the transmission medium, so that the industrial gatekeeper has a 2 + 1 architecture mode, the respective working energy consumption of the inner end machine andthe outer end machine in the industrial gatekeeper can be effectively reduced, the working efficiency is improved, the service life is prolonged, and meanwhile, the overall safety of the industrial gatekeeper is more effectively improved; The invention is suitable for interests of an enterprise.

Description

technical field [0001] The invention relates to the technical field of industrial network gates, in particular to a technology for realizing data collection and forwarding by an industrial network gate based on a 2+1 architecture. Background technique [0002] The gatekeeper is an information security device that uses a solid-state switch with multiple control functions to read and write media and connects two independent host systems. Since the two independent host systems are isolated through the gatekeeper, there is no physical connection for communication between the systems. , logical connection and information transmission protocol, there is no information exchange based on the protocol, but only non-protocol ferry in the form of data files, therefore, the gatekeeper logically isolates and blocks all potential attacks on the intranet The network connection prevents external attackers from directly invading, attacking or destroying the internal network, and ensures the ...

[0002] The gatekeeper is an information security device that uses a solid-state switch with multiple control functions to read and write media and connects two independent host systems. Since the two independent host systems are isolated through the gatekeeper, there is no physical connection for communication between the systems , logical connection and information transmission protocol, there is no information exchange based on the protocol, but only non-protocol ferry in the form of data files. Therefore, the gatekeeper logically isolates and blocks all potential attacks on the intranet The network connection prevents external attackers from directly invading, attacking or destroying the internal network, and ensures the security of internal hosts. Industrial gatekeepers are one of the gatekeepers, but the existing industrial gatekeepers have low security and energy The consumption is large, which is not conducive to the interests of the enterprise itself. Therefore, we propose a technology based on the 2+1 architecture of the industrial network gateway to realize data collection and forwarding
