Industrial Control Systems (ICS) are known as Industrial Control systems, which are widely used in various social fields, especially those critical infrastructures related to national civilization and national security, including energy production, power transmission, chemical industry, medical treatment, communication, and municipal facilities. The industrial control system in China already bears over 80% of the automatic operation tasks of key infrastructure, and becomes the important content of national strategy.
With the deep progress of the strategic deployment of 'internet +' and 'china manufacturing 2025', an industrial control system is continuously fused with new technology, more and more industrial devices adopt standardized protocols and are continuously accessed to the internet, the original specificity and closure of the industrial control system are opened, network security risks are inevitably increased, once the industrial control system is invaded or attacked, the devices are damaged, the personnel are injured and killed, the system is shut down and stopped, and the society is agitated and the country is uneasy. Since 2010, after the virus event of 'earthquake network', the network attack for the industrial control system is endless and increasing every year, and the attack means is more complex and diversified. In particular, in recent years, the complex external international environment aggravates the network security risk of the industrial control system, the security threat of the industrial control system is increasingly aggravated, and the industrial control system gradually permeates into a plurality of key fields of industrial production and national economic life. On the basis of best practices in the information security industry, in combination with the security problems of the industrial control system, research on the vulnerability of the industrial control system is urgently needed to be strengthened, and a targeted solution and a security protection measure are provided.
However, in the face of increasingly severe safety situation of the industrial control system, the network safety research of the industrial control system is relatively delayed. At present, several aspects related to industrial control systems are researched, namely the construction problem of an attack model and a safety protection system of the industrial control system, the excavation and utilization problem of security holes of the industrial control system, the test verification problem of the safety technology of the industrial control system, the dynamic protection problem of components of the industrial control system and the active defense problem of the industrial control system.

The current testing and verifying scenes aiming at the information security field of the industrial control system are insufficient, the industrial pertinence is insufficient, and the characteristic recovery of the industrial control system is not obvious. And in particular, industrial systems that can characterize municipal, traffic, etc. process control systems are lacking. And the safety test platform for industrial control systems and products at present lacks in universality, cannot be compatible with various different types of equipment, and is complex and time-consuming in replacement and disassembly of industrial control equipment.
The invention provides a simulation test platform 100 for a sewage treatment process control system, aiming at the defects of the safety test and verification simulation environment platform in the field of industrial information safety, the lack of the universality of the current safety test platform, the incapability of being compatible with various types of equipment, the complexity and time consumption for replacing and disassembling industrial control equipment and the like.

In addition, the simulation test platform 100 integrates double-container water tank liquid level control, multi-controller switching and sewage treatment integration to form a multifunctional industrial control system simulation test platform 100, and a practical and universal test platform for information safety of an industrial control system is realized. The simulation test platform 100 can not only provide an experiment model and a platform for the research of a nonlinear experiment control system; and a verification platform is provided for the research of the control system security defense algorithm, the device reaction in the industrial control field under attack can be simulated, and the damage condition of the industrial control device under attack can be displayed obviously.
The simulation test platform 100 can be compatible with various controllers 110 such as a PLC (programmable logic controller), an RTU (remote terminal unit) and the like and configuration software, simulate the site of a sewage treatment process control system in a real scene, refine and restore the operation logic of the process control system, present the process flow of the sewage treatment process, and realize data acquisition and analysis of a sewage treatment scene after remote attack, so that technicians can conveniently research the safety vulnerability discovery and protection of the industrial control system.

Step 1: sewage treatment process control system simulation test platform 100 integral structure
The simulation test platform 100 not only needs to meet the requirements of scene simulation of a sewage treatment process control system site, refine and restore operation logic of the process control system, present a process flow of the sewage treatment process, realize data acquisition and analysis of a sewage treatment scene after remote attack, but also needs to provide a platform environment for safety test of industrial control equipment, so that the overall architecture comprises a sewage treatment process display function, an upper computer configuration control function, real-time operation data acquisition, data input and output, logic control, electrical control, mechanism operation and the like, and is specifically shown in fig. 1 and 2.
Step 2: sewage treatment process control system simulation test platform 100 operation flow
The flow process and working process of the sewage treatment process are briefly described below, as shown in fig. 2 and 3. First, the first valve F1 and the third valve F3 are opened, and the first pump 710 (negative pressure pump/power pump) is started, so that the sewage in the sewage tank 20 is dialyzed into the membrane through the MBR membrane under the action of pressure difference, and other pollutants are continuously remained in the sewage tank 20 due to the fact that the pollutants cannot permeate the MBR membrane due to factors such as the structure of the pollutants, and thus, the sewage is treated and purified.
Subsequently, the dialyzed clean water is supplied to the clean water tank 30 through the first pipe S1, and the separation of water and contaminants in the contaminated water is performed. Then, the treated clean water is supplied to the first water tank 410 (assumed here as a user) through the second pipe S2 by the action of the second pump body 720 (straight flow pump). Wherein the first water tank 410 can supply water to the second water tank 420 (if assumed to be a sewage tank) through the second valve body F2 (proportional valve), and the second water tank 420 can discharge water to the sewage tank 20 again through the second drain pipe S42, wherein the first drain pipe S41 is provided with a first drain valve F6, and the second drain pipe S42 is provided with a second drain valve F7 (on-off valve).
The sewage reaches the clean water tank 30 after being re-purified, and the process realizes the re-use of the purified water. The sewage tank 20 and the clean water tank 30 are both provided with a liquid level limit switch 820 to detect the height of the liquid level and ensure the normal sewage treatment and clean water supply. The whole process is repeated in this way, and the sewage is circularly treated, purified and recycled.
Finally, after the test process is finished, the sewage tank 20 and the clean water tank 30 may discharge water through the first and second water discharge pipes S71 and S72, respectively.
And step 3: municipal administration sewage treatment process simulation test platform 100 holds water tank liquid level control system doubly
The simulation test platform 100 is internally provided with a set of double-container water tank liquid level control system, so that not only can the civil water dispatching and water recycling in municipal sewage treatment be simulated, but also a set of nonlinear experiment control system research and experiment platform environment can be provided. The specific process is as follows: the first water tank 410 and the second water tank 420 are respectively communicated with the sewage tank 20 through a first drain pipe S41 and a second drain pipe S42, the first drain pipe S41 and the second drain pipe S42 are respectively provided with a switch valve (a first drain valve F6 and a second drain valve F7), and the conversion of a single-containing water tank and a double-containing water tank can be realized through the combined action of the liquid level sensors 810 arranged on the first water tank 410 and the second water tank 420, a second valve body F2 (a proportional valve) and the second pump body 720. When the actual liquid level is lower than the set liquid level, the second valve body F2 or the second pump body 720 is started to add water; when the actual liquid level is higher than the set liquid level, the water is drained through the first drain pipe S41 and the second drain pipe S42, so that the balance of the water level can be dynamically adjusted through the created system model and the control algorithm.

The sewage treatment process is monitored through the configuration software of the human-computer interaction upper computer, and commands are sent to the system to start running, drain processing, system shutdown and the like, so that the actions of the controllers 110 and the execution mechanisms are coordinated. And meanwhile, information data uploaded by the lower computer, the sensor, the transmitter and other components are received, and sewage treatment, conveying and utilization of clean water and recycling are carried out through a built-in logic control program.
