Embodiment Construction

[0038] Such as Figure 1 to Figure 4 As shown, the present invention predicts and prevents possible system crashes, data tampering and other factors by changing the monitoring methods of traditional control station access objects, data transmission and operating status, and can effectively defend against threats such as viruses and protect Information security for industrial control systems.

[0039] Such as figure 1 As shown, the DCS information security control station of the present invention adopts a dual-engine mode to drive and control the calculation execution and security management of configuration data, and its interior is composed of two parts: a security engine and a control engine.

[0040] The control engine is mainly responsible for the calculation and execution of the control configuration algorithm, equipment IO processing and communication management between the control engine and the upper computer and the control station;

[0041] The security engine is m...

Abstract

The invention provides a DCS information safety control method and control station. A control engine and a safety engine are arranged in the control station. The control engine controls computation execution of a configuration algorithm, equipment IO processing, and communication management between the control engine and a host computer and between the control engine and the control station. The safety engine takes charge of the safety detection and defense of the control engine, including access object safety monitoring of the control station, communication data accuracy verification, and control engine execution state detection. When a protective switch of the control station is activated, it requires the detection and the verification of the safety engine for the host computer to send any data or operation access request, and the safety engine feeds detection results of abnormal data and abnormal operation back to the host computer, and gives a real-time alarm about an abnormal case. The DCS information safety control method may solve technical problems that an industrial control system control station is usually attacked by threat such as a virus or the like and an operation fault of the control station is difficult to diagnose in a visualized manner.

Description

technical field [0001] The invention relates to an industrial automation control technology, in particular to a DCS information security control method and a DCS information security control station. Background technique [0002] Nowadays, more and more field control stations of industrial control systems use commercial PLC or industrial PC products. These commercial devices are compatible with many common network protocols, and generally use standardized programming languages ​​such as IEC61131-3, which are likely to cause security vulnerabilities. Illegal intrusion by threats such as viruses and malware. [0003] The software and hardware platforms of traditional industrial control systems have serious vulnerabilities. For example, the Stuxnet virus obtains system control authority by uploading MC7 (assembly language) code, infects the PLC controller in the industrial network, and modifies the DLL communication link. Thus destroying the normal operation of the PLC, and ev...
