Description

Technical Field

[0001] This invention relates to the field of nuclear power simulator operation and maintenance, and in particular to an intelligent monitoring and early warning system for nuclear power simulators. Background Technology

[0002] During the operation and maintenance of nuclear power plant simulators, it is necessary to monitor data from all dimensions, including the physical host hardware status, network equipment operating parameters, and simulator model software health, in real time to ensure the continuous and stable conduct of core tasks such as nuclear power plant operator training and examinations.

[0003] The patent application with publication number CN116225856A in the prior art has the characteristics of flexible configuration, strong scalability and convenient maintenance through the system described above;

[0007] It is highly portable; for different nuclear power simulator environments, you only need to select the appropriate template.

[0008] Applicable to the entire lifecycle of a nuclear power simulator.

[0009] However, the current system only mentions basic permission management and SNMP protocol password configuration, without building a full-link data encryption mechanism, and does not specify the retention period and traceability capability of operation audit logs. It cannot meet the stringent requirements of nuclear safety regulations such as HAF102 for data leakage prevention, tamper prevention and operation traceability. At the same time, the solution does not disclose the high availability architecture design of the server. If the server fails at a single point, it will cause the entire monitoring system to fail.

[0040] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0041] First Embodiment

[0042] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in, Figure 1 This is a schematic diagram of the structure of a first embodiment of an intelligent monitoring and early warning system for a nuclear power simulator provided by the present invention; Figure 2 for Figure 1 The diagram shows the structure of the security module group. Figure 3 for Figure 1 The diagram shows the intelligent operation and maintenance efficiency module group. Figure 4 for Figure 1 The diagram shows the structural layout of the cost module group. A nuclear power simulator intelligent monitoring and early warning system includes:

[0043] Security assurance module group, intelligent operation and maintenance efficiency module group, and cost module group;

[0044] The security module group includes a data security encryption module, an operation audit and traceability module, and a high availability protection module;

[0045] The intelligent operation and maintenance efficiency module group is wirelessly connected to the security module group. The intelligent operation and maintenance efficiency module group includes an AI fault prediction module, a Bayesian root cause analysis module, and a templated deployment module.

[0046] The cost module group is wirelessly connected to the intelligent operation and maintenance efficiency module group, and the cost module group includes an intelligent healing module and a template and automatic adaptation module.

[0047] The data security encryption module includes a transmission encryption unit and a storage encryption unit.

[0048] The transmission encryption unit adopts the TLS 1.3 encryption protocol. When the monitoring end and the server establish a connection, it automatically completes the ECDHE key exchange and AES-256-GCM encryption algorithm configuration to ensure that sensitive data such as simulator operating parameters and fault logs exist in encrypted form during transmission, and only the server can decrypt them with a dedicated key. The storage encryption unit enables transparent data encryption for relational databases, encrypts sensitive fields such as key simulator configuration parameters and operator permission information separately, and the time series database uses the encryption bucket function to encrypt and store real-time monitoring data. The encryption key is stored through a hardware encryption module.

[0049] Deploy an audit log database on the server side and set the log retention period to a long period of years to cover all scenarios including configuration operations, user operations, and self-healing operations.

[0050] The high availability guarantee module includes a server cluster unit and a data synchronization unit.

[0051] The templated deployment module includes a template knowledge unit and an automatic monitoring item generation unit.

[0052] The template and automatic adaptation module includes a template customization extension unit and a device software automatic adaptation unit.

[0053] When the simulator experiences a lag, the multi-dimensional data association unit automatically extracts data such as network latency, CPU usage, and model data packet loss rate within a specified time before and after the lag, and constructs an association graph; the Bayesian network analysis unit calculates the probability of each factor's influence based on the graph.

[0054] The working principle of the intelligent monitoring and early warning system for a nuclear power simulator provided by this invention is as follows:

[0055] Data collection and secure transmission: The agent collects network load data, transmits it to the server via TLS 1.3 encryption, and stores it in an InfluxDB encrypted bucket;

[0056] Fault prediction and early warning: The AI ​​fault prediction module detected a continuous increase in network load, and the LSTM model predicted the "probability of reaching the threshold within 30 minutes", and the early warning was pushed to the operation and maintenance manager;

[0057] Fault occurrence and root cause location: If not intervened in time, network load will cause communication delays. The Bayesian root cause analysis module locates the root cause as overload of switch port traffic and visualizes the root cause chain.

[0058] Tiered self-healing and work order push: When the fault level is determined to be a general fault, the intelligent self-healing module automatically resets the port and pushes a work order to the operation and maintenance personnel.

[0059] Operation Log and Template Optimization: The operation audit and traceability module records the self-healing process, and the template customization extension unit adds the port traffic overload self-healing strategy to the corresponding template for reuse in subsequent projects.

[0060] Compared with related technologies, the intelligent monitoring and early warning system for nuclear power simulators provided by this invention has the following beneficial effects:

[0061] This invention provides an intelligent monitoring and early warning system for nuclear power simulators. Through the coordinated operation of the safety assurance module group, the intelligent operation and maintenance efficiency module group, and the cost module group, it solves the requirements of "data leakage prevention, tamper prevention, and operation traceability". The LSTM model improves the accuracy of fault prediction; Bayesian root cause analysis shortens the fault location time, reduces the risk of simulator downtime, and ensures the continuous training of operators.

[0066] The mounting rod 7 is installed at the bottom of the data acquisition unit 1.

[0067] The main body 1 of the data acquisition unit is made of aluminum alloy. The main body 1 has built-in temperature, voltage and current acquisition sensors for collecting host hardware operation data. The disassembly cover 2 is connected to the positioning groove 3 of the main body 1 of the data acquisition unit by positioning block 4. The positioning block 4 is made of elastic rubber to ensure a tight fit and easy disassembly.

The heat dissipation component 8 includes a heat dissipation mesh 81, a plurality of mounting blocks 82 and a plurality of bolts 83. The heat dissipation mesh 81 is disposed on the surface of the disassembly cover 2, and the plurality of mounting blocks 82 are respectively connected to both sides of the heat dissipation mesh 81.

[0076] The heat dissipation mesh 81 adopts a copper honeycomb structure and covers the surface of the disassembly cover 2. Copper has high thermal conductivity and can quickly conduct heat inside the collector. There are four mounting blocks 82 made of ABS plastic, which are fixed to the four corners of the heat dissipation mesh 81. Each mounting block 82 has a bolt hole. The bolts 83 are cross-head countersunk bolts made of stainless steel to prevent rust from affecting disassembly.

[0077] The working principle of the intelligent monitoring and early warning system for a nuclear power simulator provided by this invention is as follows:

[0078] Cover the surface of the disassembly cover 2 with the heat dissipation mesh 81, so that the bolt holes of the mounting block 82 are aligned with the reserved holes of the disassembly cover 2;

[0079] Take bolt 83, pass it through the bolt hole of mounting block 82 and the reserved hole of disassembly cover 2, and tighten it with a Phillips screwdriver to ensure that heat dissipation mesh 81 and disassembly cover 2 fit tightly together;
