Abstract

The invention provides a credible protocol conversion method which is used for protocol conversion between a first industrial control system and a second industrial control system. The method comprises the steps of receiving an external access request to be transmitted to the first industrial control system; judging the legality of the external access request according to a preset white list, and judging the access types of the external access request, wherein the access types include a data query request and a control operation request; when the external access request is the data query request, grouping the state data queried by the first industrial control system according to the protocol of the second industrial control system, and sending to the second industrial control system; and when the external access request is the control operation request, grouping the control operation request according to the protocol of the first industrial control system, and sending to the first industrial control system. Correspondingly, the invention also provides a credible protocol conversion system. According to the invention, the delay of the communication between the industrial control systems can be alleviated, and the reliability of the communication between the industrial control systems can be promoted.

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 The internet. [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 co...
