Abstract

The invention discloses an industrial security communication gateway, which comprises a data receiving port connected with a lower computer system, a data sending port connected with an upper computer system, and an embedded platform connected between the two ports. The industrial security communication gateway comprises two embedded systems and a public cache, wherein the two embedded systems have different functions; the first embedded system comprises a data receiving module, a data resolving module and a data encrypting module; and the second embedded system comprises a data decrypting module and a data sending module. By the industrial security communication gateway, the security of the industrial security communication gateway can be improved.

Description

technical field [0001] The invention relates to the technical field of industrial communication, in particular to an industrial safety communication gateway. Background technique [0002] At present, in the "digital" factory process, it is necessary to uniformly monitor the equipment status and process parameters in the lower computer systems such as factory automation, metering, and weighing instruments. However, due to the wide variety of monitoring equipment, the diversification of equipment communication protocols, the geographical dispersion of equipment, and the inconsistency of enterprise information software standards, the problem of communication protocol conversion in the networking of various systems has become more and more prominent. Since information cannot be shared , The relative isolation of data and the differences in communication protocols have formed the "information island" of the enterprise, which has seriously affected the process of enterprise inform...
