Embodiment 1

[0034] The overall structure of the present embodiment test bed is as follows figure 1 shown. The system includes physical layer, control layer and monitoring layer, which belongs to the typical layered structure of industrial control system. Among them, the physical layer adopts sewage treatment Matlab model and semi-physical model; the control layer adopts GE RX3i programmable controller, and the monitoring layer adopts KingScada configuration software. The controller and monitoring computer are connected through Ethernet, and the test equipment is also connected to Ethernet to realize the attack test on the test bed. In this system, data communication is the key. The unit of data communication mainly includes Matlab simulation program, man-machine interface and PLC. Adopt GE's IGSOPC server.

[0035] The information flow of the whole system is as figure 2 shown. The process measurement parameters of the Matlab simulation are related to the measurement input of the PI...

Abstract

The present invention relates to a virtual and actual combined sewage treatment plant test bed and a construction method thereof. The test bed comprises a physical layer, a control layer and a monitoring layer. The physical layer comprises a sewage treatment process process simulated virtual part and a semi-physical simulation part. A sewage treatment process process simulated computer carries out numerical simulation on a sewage treatment process and transmits the process parameter obtained from the simulation to a semi-physical simulation system. The control layer comprises a GE company RX3i model PLC. The monitoring layer comprises a monitoring computer, network equipment and test equipment. The intuitive characteristic and dynamic sense are good in the process simulation and display of the sewage treatment process, a physical model and a digital simulation system are integrated well, and the effect after attacking a sewage treatment control system can be displayed. The data exchange between two sides is realized by using the object link of process automation and the embedding technology OPC technology, the flexibility is high, and no hardware wire connection is realized.

Description

technical field [0001] The invention belongs to the field of industrial control simulation and emulation, and mainly relates to a virtual-real combined sewage treatment plant test bed and a construction method thereof. Background technique [0002] Test beds are widely used in information security research for industrial control systems. Currently commonly used test bed construction schemes include software simulation, physical or semi-physical simulation, and a combination of simulation and simulation (combination of virtual and real). Software simulation adopts software simulation method, which has high flexibility, but poor presentation and not intuitive enough. Although the hardware-in-the-loop simulation is more intuitive and real, it has high cost and poor flexibility. However, the method of combination of virtual and actual has concentrated the advantages of the above two methods to a certain extent, and overcomes their respective shortcomings. [0003] The existin...
