Description

Technical Field

[0001] This application relates to the technical field of data processing, and particularly to a method for secure storage and management of thermal power SCR denitration process data. Background Art

[0002] The SCR (Selective Catalytic Reduction) denitration process mainly relies on a denitration reaction device installed in the flue gas duct. Through chemical reactions between reducing agents such as ammonia and nitrogen oxides under the action of a catalyst, harmful nitrogen oxides are converted into harmless nitrogen and water, thereby realizing the purification treatment of flue gas. During this process, many key parameters such as ammonia concentration, nitrogen oxide concentration, and liquid level reflect the reaction progress and the operating state of the device in real time. Their accurate monitoring and control are of great significance for ensuring the denitration effect and maintaining the stable operation of the system.

[0003] However, in the traditional denitration process flow of thermal power plants, with the integration of industrial Internet of Things technology, although the convenience of data collection and transmission has been improved to a certain extent, many security risks have also been exposed. Most existing systems adopt a centralized data storage architecture. Once a single-node device, such as a sensor or a data collector, is maliciously attacked or controlled by criminals, due to the lack of an effective data anti-tampering mechanism, attackers can easily tamper with key data, leading to the risk of information leakage and then maliciously controlling the entire denitration process.

[0004] In view of this, we need a method for secure storage and management of thermal power SCR denitration process data to solve the above problems. Summary of the Invention

[0005] The purpose of this application is to solve the problem that most existing systems adopt a centralized data storage architecture, which can easily tamper with key data and lead to the risk of information leakage. To solve the above technical problems, a method for secure storage and management of thermal power SCR denitration process data is provided, which can effectively prevent any single-node device from easily tampering with key data and causing the risk of information leakage.

[0006] To achieve the above object, the embodiments of the present application adopt the following technical solutions: Automatically collect the monitoring data of key indicators during the reaction process at a preset frequency, which can be dynamically adjusted according to the emission standards of the thermal power industry and the real-time monitoring requirements. The collected monitoring data of key indicators forms terminal data; Extract key data from the enterprise resource planning system and the manufacturing execution system of the production management system as system data, and simultaneously upload the terminal data and the system data to the data management system through a link to form trusted data; Adopt a storage mechanism of one chain with multiple ledgers, isolate and keep confidential the trusted data based on the group dimension, send the transaction to a specific group to which the node belongs, and the specific group conducts consensus on the transaction and the trusted data and stores them; Based on the changes in the input parameters of the intelligent contract and the SCR denitration reaction device and the data of the Internet of Things devices, trigger the demand response to go on-chain, and generate curves and charts by recording the associated changes in the device input parameters, adjustment parameters, and system data; After sending a transaction request and automatically performing a transaction behavior through a distributed application accessing the data management system, generate transaction information and store it in the cloud database.

[0007] Further, according to the embodiments of the present application, the preset frequency includes a key monitoring period and a non-key monitoring period. When the preset frequency is set to once every 5 minutes during the key monitoring period, and when the preset frequency is set to once every 15 minutes during the non-key period.

[0008] Further, according to the embodiments of the present application, when conducting consensus and storage, a distributed cloud storage strategy is adopted, and the trusted data is scattered and stored on multiple cloud servers, and the cloud platform infrastructure is used to achieve creation and deployment, and the resource configuration is flexibly adjusted according to business requirements.

[0009] Further, according to the embodiments of the present application, when the trusted data is scattered and stored on multiple cloud servers, a redundant backup strategy is adopted, and the trusted data is synchronously stored on at least three cloud servers in different geographical locations to cope with the risk of single-point failure.

[0010] Further, according to the embodiments of the present application, when the key indicator data of the SCR denitration device is monitored, an early warning message is immediately sent to relevant supervisors and auxiliary supervision decisions are made.

[0011] Further, according to the embodiments of the present application, a double encryption method is adopted during the data transmission process. First, the trusted data is encrypted based on the industry-standard encryption algorithm, and then the encrypted trusted data is secondarily encrypted using the blockchain hashing algorithm.

[0012] Further, according to the embodiments of the present application, based on the group access mechanism and the network access review basis, an additional environmental protection compliance review of the organization where the application node is located is added, and only the nodes that pass the environmental protection compliance review can enter the specific group.

[0013] To achieve the above object, the embodiments of the present application also adopt the following technical solutions: a thermal power SCR denitration process data security storage and management system, which includes: a data acquisition module, which is used to automatically acquire the key index monitoring data during the reaction according to a preset frequency. The preset frequency can be dynamically adjusted according to the thermal power industry emission standards and real-time monitoring requirements.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components.

[0025] For the sake of simplicity and illustration, the principles of the embodiments are mainly described by referring to examples. In the following description, many specific details are set forth to provide a thorough understanding of the embodiments. However, it is obvious that for those of ordinary skill in the art, these embodiments may not be limited to these specific details in practice. In some instances, well-known methods and structures are not described in detail to avoid unnecessarily obscuring these embodiments. Additionally, all embodiments can be used in combination with each other.

[0026] Embodiment 1:

[0027] As Figure 1 shown, this embodiment provides a method for secure storage and management of thermal power SCR denitration process data. Among them, this method is applied to a secure storage and management system for thermal power SCR denitration process data, and this method includes:

[0028] S10. Automatically collect key index monitoring data during the reaction process at a preset frequency, and the preset frequency can be dynamically adjusted according to the thermal power industry emission standards and real-time monitoring requirements. The key index monitoring data after collection forms terminal data;

[0029] By setting sensors at key parts of the denitration reaction device, the sensors are used to automatically collect data at a preset frequency. For example, the ammonia concentration sensor can continuously sense the concentration change of the reducing agent ammonia, the nitrogen oxide concentration sensor can accurately capture the content fluctuation of harmful nitrogen oxides in the flue gas, the temperature sensor can closely monitor the reaction temperature, the pressure sensor can constantly pay attention to the system pressure dynamics, the flow sensor can accurately measure the flow rates of media such as ammonia and flue gas, and the liquid level sensor can closely monitor the liquid level of relevant storage containers.

[0030] During the key stage of the prevention and control of air pollution in key areas, to ensure real-time and accurate monitoring of the reduction effects of pollutants such as nitrogen oxides, the preset frequency is greatly increased, and it can be shortened to be collected once every 5 minutes or even at shorter intervals. This enables the system to capture the slightest fluctuations in emission data at the fastest speed, so as to feed back to the subsequent processing links in a timely manner.

[0031] S20. Extract key data from the enterprise resource planning system and the manufacturing execution system in the production management system as system data, upload the terminal data and the system data to the data management system through the upper link at the same time, and form trustworthy data;

[0032] S30. Adopt a storage mechanism of one chain with multiple ledgers, isolate and keep confidential the trustworthy data based on the group dimension, send the transaction to a specific group to which the node belongs, and the specific group conducts consensus on the transaction and the trustworthy data and stores them;

[0033] Further, according to the embodiments of the present application, when conducting consensus and storage, a distributed cloud storage strategy is adopted to disperse and store the trustworthy data on multiple cloud servers, use the cloud platform infrastructure to achieve creation and deployment, and flexibly adjust the resource configuration according to business requirements.

[0034] Further, according to the embodiments of the present application, when the trustworthy data is dispersed and stored on multiple cloud servers, a redundant backup strategy is adopted to synchronously store the trustworthy data on at least three cloud servers in different geographical locations to cope with the risk of single-point failure and ensure the persistent availability of the data.

[0035] Exemplarily, in the data management blockchain layer of the SCR denitration process in a thermal power plant, the one-chain multi-ledger storage mechanism divides the participants into groups according to the business entity, data type, and access authority. For example, the production department, the technical team, and the government department each form a group. The client sends a transaction to the corresponding group, and the group strictly verifies and stores the transaction and the data according to consensus algorithms such as PBFT. Other groups are unaware, preventing data leakage and illegal access, and ensuring that sensitive information flows within the authorized scope.

[0036] Adopt a storage mechanism of one chain with multiple ledgers to achieve data isolation and confidentiality on the same chain based on the group dimension. The client sends the transaction to a certain group to which the node belongs, and the group conducts consensus on the transaction and the data and stores them internally. Other groups are unaware and invisible to the transaction. Moreover, a distributed cloud storage strategy is adopted to disperse and store the data on multiple cloud servers, use the cloud platform infrastructure to achieve creation and deployment, and flexibly adjust the resource configuration according to business requirements to ensure that the computing power and storage capacity can be expanded or contracted as needed;

[0037] The distributed cloud storage strategy disperses and stores the SCR denitration process data on multiple cloud servers, and uses the cloud platform infrastructure to quickly create and deploy the system, eliminating the traditional hardware procurement and computer room construction processes. Moreover, as the business requirements of the thermal power enterprise change, such as the peak and trough of power generation and the data scale fluctuation caused by process upgrade, the system can flexibly adjust the resource configuration, and use the elastic scaling function of the cloud platform to expand or contract the computing and storage capacity as needed to ensure the stable storage of the data.

[0038] S40. Trigger the demand response to be uploaded to the blockchain based on the changes in the input parameters of the SCR denitration reaction device and the data of the Internet of Things devices. Generate curves and charts by recording the associated changes in the device input parameters, adjustment parameters, and system data.

[0039] Specifically, in the data management system of the SCR denitration process in thermal power plants, strengthen the incentive control of the power supply transfer entity and end-users, and give full play to the effectiveness of smart contracts. Define the reward settlement method: For the power supply transfer entity that accurately adjusts the power supply during peak electricity consumption, ensures stable power supply for the denitration device, etc., and meets the quality standards, give rewards such as electricity bill subsidies and priority power supply rights according to the proportion of the adjusted electricity volume, and settle monthly or quarterly; For end-users who respond to the energy-saving initiative of the power plant and reduce the electricity load during non-production necessary periods to assist the denitration process, obtain rewards such as integral redemption for gifts and electricity bill reduction according to the reduced electricity consumption, and the points are accumulated in real-time and exchanged regularly. Establish reward fulfillment rules: Embed multiple verifications in the smart contract, jointly with the bank to ensure the exclusive reservation of the reward funds, and supervise the release conditions and process with a third-party notary institution to prevent fraud. The smart contract triggers the demand response to be uploaded to the blockchain based on the data changes of the denitration device and the Internet of Things devices. For example, when there are fluctuations in the ammonia input volume, the initial concentration of nitrogen oxides, the temperature setting value, or abnormalities in the fan speed and pipeline pressure, capture and package them and upload them to the blockchain. Continuously record the associated changes, and use visualization tools to generate curve charts to present the real-time dynamics of the process, assist in tracing the data source and troubleshooting, and improve data management and operation efficiency.

[0040] S50. After sending a transaction request and automatically performing a transaction behavior through a distributed application accessing the data management system, generate transaction information and store it in the cloud database.

[0041] In the data management ecosystem of the SCR denitration process in thermal power plants, the interaction between users and the system is crucial. All personnel in various departments within the thermal power plant, external power supply transfer entities, and the public concerned about thermal power environmental protection, etc., if they need to deeply participate in data management and business collaboration, can access the blockchain platform system through distributed applications. For example, when production department personnel monitor the SCR denitration device and find that key parameters are abnormal and need to adjust material or equipment parameters, they can send a transaction request through the distributed application, including instructions such as adjusting the ammonia injection volume and replacing the catalyst. After the system receives it, it automatically conducts transactions according to the smart contract. If the contract verifies that the request is legal and reasonable, it will execute, generate transaction information containing the operation content, time, and personnel identification, and store it in the blockchain cloud database. Due to its characteristics, it can be permanently and reliably stored for subsequent analysis and traceability.

[0042] At the same time, to facilitate users to use the system functions, the application layer provides various blockchain access methods. For example, professional users such as the technology R & D department have deeply customizable development tools; the public users can check the thermal power environmental protection information through the web page. By improving the access and interaction mechanism, achieve efficient linkage between all parties and the system, and help improve the data management of the thermal power industry.

[0043] Further, according to the embodiments of the present application, the preset frequency includes a key monitoring period and a non-key monitoring period. When the preset frequency is set to once every 5 minutes during the key monitoring period, and when the preset frequency is set to once every 15 minutes during the non-key period.

[0044] Further, according to the embodiments of the present application, when the key index data of the SCR denitration device is monitored, a warning message is immediately sent to relevant supervisors and auxiliary supervision decisions are made.

[0045] Further, according to the embodiments of the present application, during the data transmission process, a double encryption method is adopted. First, the trusted data is encrypted based on the industry standard encryption algorithm, and then the encrypted trusted data is secondarily encrypted using the blockchain hash algorithm to ensure the security of data transmission and prevent data leakage and tampering.

[0046] Further, according to the embodiments of the present application, based on the group access mechanism and the network access review basis, an additional environmental protection compliance review of the organization where the application node is located is added. Only the nodes that pass the environmental protection compliance review can enter a specific group to ensure the legality and standardization of data interaction within the group.

[0047] The blockchain distributed storage feature can provide real-time distributed data storage for each important node of the SCR denitration process in thermal power plants. The anti-tampering feature can effectively prevent the risks of information leakage and malicious control caused by any single-node device in the industrial Internet of Things being maliciously attacked and controlled. In this way, a reliable, transparent and traceable, highly scalable, easy to maintain, stable and high fault tolerance data management system is constructed. By building a blockchain platform, the Internet of Things devices and communication networks, enterprise resource planning systems, production management systems, manufacturing execution systems, product life cycle management software and other systems on the SCR denitration process production line are connected, so that records such as equipment operation, production, and maintenance can be read through the blockchain management system, and relevant data can be dynamically grasped in real time.
