Abstract

The present invention provides a trusted protocol conversion method for protocol conversion between a first industrial control system and a second industrial control system. The method includes: receiving an external access request to be sent to the first industrial control system; The list judges the legitimacy of the external access request, and judges the access type of the external access request, and the type includes a data query request and a control operation request; when the external access request is a data query request, the status queried from the first industrial control system The data is grouped according to the protocol of the second industrial control system and sent to the second industrial control system; when the external access request is a control operation request, the control operation request is grouped according to the protocol of the first industrial control system and sent to the first An industrial control system; correspondingly, the present invention also provides a trusted protocol conversion system; the present invention reduces the delay of communication between industrial control systems, and improves the reliability of communication between industrial control systems.

Description

technical field [0001] The invention relates to the technical field of industrial information, in particular to a trusted protocol conversion method and system. Background technique [0002] With the rapid development of industrial automation control, more and more industrial enterprises use their internal (or private) network to interconnect their production process special equipment or industrial intelligent equipment (Intelligent Electric Device, referred to as "IED") to form a production Control system network. [0003] Various industrial control network protocols are based on the ISO / OSI open system interconnection model. The OSI reference model is divided into 7 layers. The industrial control network communication protocol is simplified according to its own specificity. It adopts the physical layer, data link layer and Network layer, while considering the control function and specific application of field devices, the application layer is added. To realize the communi...
