In the face of the increasingly severe industrial control security situation, the network security research on industrial control systems in the energy industry is relatively lagging behind. Throughout the current research progress of industrial control information security, it mainly focuses on the construction of industrial control attack models and protection systems, the mining of industrial control system security vulnerabilities, the dynamic protection of industrial control systems, the active defense of industrial control systems, and the testing and verification of industrial control system security issues, etc. question. Since the research on the above problems needs to provide research objects and test verification platforms, the establishment of a safe test environment platform device for industrial control systems in the energy industry is the most important link at present.

Investigating the simulation test environment platform devices currently built in the energy industry, most of them have problems such as insufficient industry pertinence, large size, high cost, and insufficient security attacks and test results. In particular, there is no complete and systematic industrial control test system for high Simulating and restoring the industrial control operating environment with simulation degree is not conducive to the evaluation of the attack and defense effects of the industrial control system, the analysis of the attack and defense scenarios, the verification of vulnerability hazards, and the evaluation of the effectiveness of security technologies. These problems seriously restrict the security research of industrial control systems in the energy industry.

To build a simulation test environment platform for the control system of the energy industry, it is necessary to select a typical industry background and a typical process technology. The process control system is a typical control system in the petroleum and petrochemical industry. Its control logic is simple and easy to understand. It generally adopts discrete control mode and can be compatible with various PLC, RTU and other controllers and different configuration software. It is a good industrial control system. Universal testbed for information security.

Based on the above background content, the present invention proposes a natural gas transportation system simulation platform 100 integrating configuration monitoring, database system, electrical control, and pneumatic control, which is compatible with various PLCs and RTUs, and simulates the process flow of natural gas transportation in reality. It presents the logic control principle of natural gas pipeline transmission site, and realizes the safety test environment platform for generalized energy transmission.

As shown in FIG. 1 , a natural gas transmission system simulation platform 100 according to an embodiment of the present invention includes: a simulated pipeline system 10 , a control system 20 , an industrial control information security system 30 and a database system 40 .

Specifically, as shown in FIG. 1 to FIG. 3 , the simulated pipeline system 10 has an input end 110 and an output end 120 . The simulated gas is input to the simulated pipeline system 10 from the input end 110 and output from the output end 120 , and the output end 120 is an analog gas. user terminal.

The control system 20 is connected to the simulated piping system 10 for controlling the simulated piping system 10 . The industrial control information security system 30 is connected to the control system 20, and the industrial control information security system 30 is used for acquiring and analyzing the operation parameter information of the control system 20.

The database system 40 is connected with the simulation pipeline system 10, the control system 20 and the industrial control information security system 30, and is used for storing the operation data of the simulation simulation platform 100.

The natural gas transportation system simulation platform 100 according to the embodiment of the present invention can simulate the process flow of natural gas transportation in real scenes, present the logic control principle of the natural gas pipeline transportation site, show the display of the natural gas pipeline transportation scene after remote attack, and the corresponding data collection and analysis , so as to facilitate technical personnel to conduct research on industrial control system security vulnerability mining and protection.

According to some embodiments of the present invention, as shown in FIG. 1 , the simulation platform 100 further includes: a configuration monitoring system 50 , and the configuration monitoring system 50 can display the simulated pipeline system 10 in real time by creating a two-dimensional and/or three-dimensional landscape map. The transport state of the simulated gas in . That is to say, the configuration monitoring system 50 can create a two-dimensional landscape map, a three-dimensional landscape map, or both a two-dimensional landscape map and a three-dimensional landscape map, so as to simulate the conveying state of the simulated gas in the simulated pipeline system 10. Real-time monitoring display.

For example, the configuration monitoring system 50 can be developed using a LabVIEW software tool programmed in a graphical language, so as to facilitate maintenance and secondary development. At the same time, LabVIEW can generate .exe and installation files for easy porting. The configuration software of the control center adopts the UNITY 3D modeling method to visually display the transmission, pressure regulation, venting and network attack effects of the natural gas pipeline in real time by creating a three-dimensional landscape map.

In some embodiments of the present invention, the simulated pipeline system 10 includes multi-stage transmission pipelines, and pressure regulating equipment is provided between adjacent two-stage transmission pipelines, and the pressure regulating equipment is connected to the control system 20 . It should be noted that in the process of natural gas delivery to the user end, the temperature and pressure, especially the pressure, of the natural gas after various separations and treatments before it is input to the residential user greatly exceed the residential pipeline and gas equipment. Therefore, it needs to be reduced to the user's use range through a multi-stage pressure regulation process. In order to restore this industrial process, the simulation platform 100 has designed a set of pneumatic pressure regulating equipment, which has functions such as gas data acquisition and pressure regulation. In this way, the gas pressure can be adjusted, and the compressed gas pressure can be reduced to the set range, so as to restore and simulate the gas supply project of residential users well.

According to some embodiments of the present invention, as shown in FIG. 3 , oil and gas separators (horizontal oil and gas separator T1 and vertical oil and gas separator T2 are shown in the figure) are provided on the transmission pipeline, which are used for oil and gas separation of simulated gas. separation. It should be noted that when natural gas is transported, oil and gas separation is required. In order to improve the authenticity of the simulation, in the present invention, by setting the oil and gas separator, the oil and gas separation process in the natural gas transportation process can be simulated, thereby improving the simulation authenticity of the simulation platform 100 .

In some embodiments of the present invention, as shown in FIG. 2 and FIG. 3 , a vent valve is provided on the transmission pipeline (the light gray valves shown in FIG. Simulate the gas for venting. It should be noted that during the natural gas transmission process, there may be a problem of pipeline bursting. At this time, the natural gas in the transmission pipeline needs to be vented to reduce potential safety hazards. In the present invention, by arranging a vent valve on the transmission pipeline, the vent valve can be controlled by the control system 20 to realize the venting of the simulated gas in the transmission pipeline, which improves the authenticity of the simulation platform 100.

According to some embodiments of the present invention, the transmission pipeline is provided with an indicator for indicating the burst status of the transmission pipeline. For example, the indicator can be a gas. By setting the gas on the transmission pipeline, when the air pressure on the transmission pipeline is greater than the preset value, the gas on the transmission pipeline will be blown out. In this way, the burst state of the pipeline during natural gas transportation can be simulated.

In some embodiments of the present invention, the industrial control information security system 30 includes: a communication module for communicating with a remote device, so as to perform remote data collection and analysis on the control system 20. It can be understood that by setting the communication module, remote and local operation control can be realized.

According to some embodiments of the present invention, the control system 20 includes: a control center, a field station, and instruments.

The control center is used for scheduling and controlling the transportation of the simulated gas in the simulated pipeline system 10 , and for allocating the management and control authority of the simulated simulation platform 100 . The control center is the intelligence and dispatching center of the entire simulation platform 100. Under normal circumstances, the operator can complete the monitoring and operation management of the entire urban gas transmission and distribution network through the computer system in the dispatching control center.

The station is used to schedule and control the delivery of simulated gas at preset simulated stations in the simulated piping system 10. It should be noted that, in the natural gas transmission industry, the control area to which the logic controller (PLC) or remote terminal (RTU) of the non-dispatching control center belongs is generally referred to as the field station. It mainly includes gate stations, pipeline network pressure regulating stations, special pressure regulating stations for key industrial users and pipeline network monitoring points, which are divided into manned stations and unmanned stations according to their importance.

Field instruments mainly include sensors, transmitters, local display instruments, intelligent instruments and actuators, which are mainly responsible for detecting and measuring the operating parameters of the current site and controlling field devices.

In some embodiments of the invention, the control system 20 includes a plurality of detachable controllers, which are programmable logic controllers or remote terminal units. In the related art, in the natural gas transmission system simulation platform, there are problems such as time-consuming and labor-intensive updating and disassembly of the controller equipment. In the present invention, the design and installation of the controller (including PLC and RTU) adopts a detachable type, that is, without changing other hardware devices and logic control electrical circuits of the system, only other brands and types of controllers can be replaced. The maintenance of the system facilitates the expansion and upgrade of the system, and improves the utilization rate of the entire platform device.

According to some embodiments of the present invention, the simulated gas is air compressed by an air compressor. For example, medical air compressors can be used to compress air, and compressed air can be used to replace natural gas, which not only ensures that the pressure range of compressed gas is consistent with that of natural gas, but also avoids environmental pollution and waste of materials. The compressed air can not only be used for normal pipeline testing, but also greatly reduces the noise in the experimental environment of the equipment.

Since the compressed gas pressure is much higher than the normal atmospheric pressure, in order to visually display the gas pressure of the pipelines at all levels, and at the same time to ensure safety, this design adopts the tire pressure valve to be added to the pipeline at all levels, through the tire pressure valve. The discoloration properties are shown.

The natural gas transmission system simulation platform 100 of the present invention will be described in detail below with reference to the accompanying drawings with a specific embodiment. It is to be understood that the following description is only an exemplary description, rather than a specific limitation of the present invention.

For the current energy industry's industrial control system information security attacks, testing and verification are insufficient, and the existing shooting range environment is not targeted enough, the industry's control process technology and industry background characteristics are not obvious. Moreover, the current range platform for the natural gas industry lacks versatility, which is not conducive to effective research on industrial control information security.

The invention proposes a SCADA (Supervisory Control And Data Acquisition) system for natural gas pipeline transportation, which integrates configuration control of upper computer, three-dimensional real-time remote monitoring, database system, lower computer controller, electrical control, and air power source, and can be compatible with multiple PLC (Programmable Logic Controller) and RTU (Remote Terminal Unit) are used to simulate the process flow of natural gas transportation in real scenes, present the logic control principle of natural gas pipeline transportation site, and realize the construction of a generalized simulation platform 100 for energy transportation. Moreover, it can realize the damage of natural gas pipeline transportation scenarios after remote attack and the corresponding data collection and analysis, so as to help technicians conduct research on the mining and protection of industrial control system security vulnerabilities.

The simulation platform 100 takes the energy industry as the background and natural gas pipeline transportation as the specific industry object, and designs the local field host computer monitoring, control center remote monitoring, database storage, electrical control, pipeline valve control, The functions of user pressure regulation and conveying, flow control and calculation are described in further detail below.

The natural gas pipeline transportation SCADA system simulation platform 100 not only needs to meet the process flow of the natural gas pipeline transportation simulation, refine and restore the operation logic of the transportation process control system, present the industrial control system scene of the transportation process, and show the control system when it is attacked. damage and data collection and analysis. The simulation platform 100 simulates the complete control system of the natural gas industry in the energy industry, which not only needs to realize the normal natural gas process processing and the corresponding data acquisition, processing, monitoring, analysis, alarm and data interaction with other management systems, but also involves the transmission of natural gas. Process-related parameters such as pressure, flow rate, temperature, etc.; and corresponding detection, monitoring, alarm, execution, etc.

The simulation platform 100 also provides a platform environment for the safety testing of industrial control equipment. Therefore, the overall architecture includes the process display function of the conveying process, the configuration control function of the upper computer, the real-time acquisition function of the operation data, the database storage function, the three-dimensional Dynamic display function, data input and output function, user login function, user authority operation function, logic control function, electrical control function, mechanism operation function, instrumentation function, etc., as shown in Figure 2-Figure 5. Among them, Figure 2, Figure 3, Figure 4 and Figure 5 are the simplified process flow diagram, the upper computer configuration, the system architecture diagram and the process composition diagram of the natural gas pipeline transportation SCADA system simulation test platform device.

The simulation platform 100 realizes the control center (remote) and on-site monitoring and management functions of simulated natural gas pipeline transportation through the cooperation of four parts, namely: control center, field station, field instrument and communication system.

Among them, whether the SCADA system of natural gas pipeline transportation works well, its communication system plays a crucial role. Usually, the communication mode applied in the natural gas pipeline transmission system consists of wired (232, 485, Ethernet and optical cable, etc.) and wireless (GSM and GPRS, etc.). In the design of the invention, 485 and Ethernet bus are used for data communication between devices and between devices and systems.

The simulation platform 100 simulates the operation process of natural gas pipeline transportation. At the same time, because natural gas itself belongs to the gas category, its parameters such as density and pressure (0-1.0MPa) are larger than those of air under normal pressure. At the same time, considering the safety and environmental protection of testers, medical air compressors (0-1.0MPa) can be used to pressurize air to replace natural gas for operation tasks, so as to realize the reduction of natural gas gas pressure characteristics and the pipeline transmission of gas Operation.

From the point of view of the process flow, the simulation platform 100 includes the components of gas transmission trunk line, gas transmission to users, high-pressure venting and low-pressure venting, control center and local field monitoring, etc. Its specific process composition and process are simplified as shown in Figure 5 and shown in Figure 2.

The main line of gas transmission means that the collected natural gas is transported to the multi-stage pipeline of the natural gas processing area through the main pipeline, and then vertical and horizontal oil and gas separation is carried out, and then the separated natural gas is transported to the pressure regulating pipeline; The gas transmission to the user is to pass the natural gas in the pressure regulating pipeline through multi-stage pressure regulation to reduce the natural gas pressure in the pipeline to the pressure range used by the user; When the pipeline is repaired, the gas in the pipeline needs to be transported to the anti-aircraft tower for combustion, so as to avoid accidents such as explosion and leakage.

The specific operation process of the simulation platform 100 is as follows:

As shown in Figure 3, firstly, start the air compressor, open the main valve F0 to charge the compressed air instead of natural gas into the main line S0, then open the first main pipeline valve F1 and the second main pipeline valve F2, at this time after the first main pipeline valve F1 and the second main pipeline valve F2 are opened. The mixed oil and gas in the primary manifold S1 reaches the horizontal oil and gas separator T1 for oil and gas separation.

Next, open the first-stage pipeline valve F11 or the second-stage pipeline valve F21 (note: the pipeline valves here correspond to each other, such as: the first-stage pipeline valve F11 and the first main pipeline valve F1 are a group; the first-stage pipeline valve F11 and the first main pipeline valve F1 are a group; The second-stage pipeline valve F21 and the second main pipeline valve F2 are a group). At this time, the mixed gas passing through the horizontal oil-gas separator T1 enters the second-stage manifold S2.

Next, open the first-stage pipeline valve F12 or the second-stage pipeline valve F22 or the third-stage pipeline valve F32, and the mixed gas entering the second-stage header S2 enters the vertical oil-gas separator T2 Vertical oil and gas separation is performed, and the separated gas will enter the third-stage manifold S3.

Next, open the first three-stage pipeline valve F13 or the second three-stage pipeline valve F23. At this time, the gas entering the third-stage manifold S3 enters the decompression area (or the pressure regulating area), and after the first adjustment Due to the decompression effect of the pressure valve P1 or the second pressure regulating valve P2, the pressure of the gas has been reduced to a certain range.

Finally, after the first pressure regulation, the gas pressure has been reduced to a certain limit. At this time, the third pressure regulating valve P3 can be used for secondary pressure regulation to supply gas to the user.

The simulation platform 100 has the function of gas venting (including low-pressure venting and high-pressure venting, as shown in Figure 5). The specific workflow is that when the main valve F0 goes to the first-level header S1, or the first-level header S1 to the second-level header S2, or the second-level header S2 to the third-level header S3, there is a pipeline leakage, etc. In case of abnormality, it is necessary to open the corresponding high-pressure vent valve to release and burn the gas stored in the pipeline, and then carry out the maintenance of the pipeline. Similarly, when an abnormality occurs after the tertiary manifold, it is necessary to open the corresponding low-pressure vent valve to release and burn the gas stored in the pipeline, and then carry out the maintenance of the pipeline.

The natural gas pipeline transportation SCADA system simulation platform 100 integrates common industrial software and hardware such as PLC, RTU, Labview configuration software, database, etc. , S7 and other industrial protocols, network attacks, vulnerability verification, security testing and risk assessment can be performed on different software and hardware (or different protocols, ports) in the platform device. In addition, by attacking the pressure regulation process during the transportation process, the degree of damage to the residential gas supply caused by the network attack can be visualized.

To sum up, the present invention is aimed at the insufficient scenarios of attack, testing and verification in the current energy industry industrial control information security field. The simulation platform 100 integrates configuration monitoring, database technology, electrical control, pneumatic control and other technologies. Simplified energy industry natural gas pipeline transportation process, pipeline valve control logic, pipeline pressure regulation process control logic, upper computer configuration monitoring system, remote central monitoring system, compressed air pressure display, electrical control cabinet, database system, gas flow measurement, High-pressure venting, low-pressure venting, vertical and horizontal gas separation processes, etc.

The real-time management, scheduling and control of the natural gas pipeline transportation process through the real-time monitoring of the upper computer configuration of the on-site operation station and the human-computer interaction of the control center, the system start-up operation, system shutdown, pipeline venting, pipeline valve control, gas flow measurement etc. to issue instructions; coordinate various controllers and actuators; at the same time, accept the information data uploaded by the lower computer, sensors, transmitters and other components, and process the gas pipeline transmission through the logic control program.

The simulation platform 100 is equipped with multi-authority operation functions such as control center and local control, and is also equipped with remote access functions, providing local and remote attack and defense test scenarios, which is more in line with current technology integration trends and security research needs.

The simulation platform 100 device can completely reproduce the process flow and business functions of the SCADA system for natural gas pipeline transportation, and at the same time can intuitively present the system response when attacked, and show the damage to industrial control equipment when it is attacked.

The simulation simulation platform 100 simulates the abnormal state phenomenon of the gas transmitted by the pipeline when the control parameters are illegally modified due to the attack on the PLC, RTU and database systems; when the simulated pressure regulator and the host computer configuration are attacked, the normal expansion of the balloon is represented by the phenomenon. The explosion phenomenon of the pipeline at the residential user end; when the simulated configuration software is attacked, the configuration software cannot display the gas information normally.
