Industrial SCADA (Supervisory Control and Data Acquisition) system simulation platform

Abstract

The invention discloses an industrial SCADA (Supervisory Control and Data Acquisition) system simulation platform. The platform can realize Modbus / TCP, IEC 60870-5-104 and BACnet / IP protocols in an industrial SCADA system. The platform is divided into four parts which are simulation module used for simulating a virtual controlled object, a PLC honeypot, an SCADA server and a protocol communicationmodule. The platform specifically simulates an industrial SCADA system network data flow including various typical industrial control protocols, adopts a construction mode based on the PLC honeypot,simulates a network data flow with large-scale nodes, multiple protocols and special interactive mode in the real industrial control system environment through realizing response behaviors of a PLC for the SCADA server and control functions for the controlled object, and realizes a complete communication process of data among a process monitoring layer, a field control layer and the controlled object in the industrial SCADA system. The industrial SCADA system simulation platform performs packaging on the PLC honeypot by using the flexibility of the simulation module for serving as the virtualcontrolled object and combining the light weight of a docker environment, thereby enabling the platform to be transplantable and expandable.

AI Technical Summary

Problems solved by technology

At present, research on the construction of security platforms for industrial control systems is still in its infancy. Most people know little about the architecture, protocols, interaction modes, and communication methods of industrial control systems. There are almost no simulation platforms for simulating the on-site environment of industrial control systems. The realization of this platform helps to understand the structure of the industrial control system itself, the format and characteristics of the protocol, and the interaction mode and mode between nodes, so as to have a more intuitive understanding and clear cognition of the typical industrial control process
