TECHNICAL FIELD
[0001] The present application relates to the technical field of intelligent operation and maintenance, more particularly to a digital analysis, prediction and disposal system for linkage between intelligent operation and emergency response. BACKGROUND
[0002] Under the background of deepening industrial digital transformation, the operation and emergency response of complex equipment clusters face multi-dimensional challenges. Modern industrial systems exhibit deep coupling characteristics of physical equipment, network architecture and business processes. The device topology evolves from linear connection to heterogeneous mesh structure. The resource pool covers multiple types of elements such as computing, storage, spare parts and bandwidth. The fault conduction path presents dynamic and nonlinear characteristics. The traditional operation and maintenance mode relies on preset rules and manual experience, which is difficult to meet the fault disposal needs of such complex systems. On the one hand, when a fault occurs, a single-point alarm often triggers a chain reaction. The existing system lacks quantitative characterization of the diffusion intensity of the fault in the topology network and can only locate the initial fault point, but cannot predict the heat conduction trend, resulting in a lag in blocking measures compared to the speed of fault spread. On the other hand, there is a time and space mismatch between resource scheduling and fault disposal. The dynamic matching of resource pool and fault area relies on static path planning, without considering the real-time changes of transmission delay and loss. Moreover, the resource feedback lacks a collaborative mechanism with blocking operations, resulting in resource redundancy or insufficient supply at critical nodes. The allocation of computing power at the edge and cloud and the data interaction delay further exacerbate the efficiency loss of fault response. When the network fluctuates or is interrupted, systems that rely on centralized decision-making in the cloud are prone to disposal stagnation, while pure edge deployment is limited by local computing power and cannot complete global path optimization. In addition, the value of historical data has not been fully tapped, and the selection of key blocking points and resource channel planning lack self-learning ability, making it difficult to adapt to changes in system characteristics caused by equipment aging and business iteration. These problems collectively make it difficult to balance the accuracy, real-time performance and resource utilization of fault disposal in complex industrial scenarios, and there is an urgent need to build an intelligent system that integrates digital analysis, prediction and linkage disposal.

[0114] When the system is deployed, a hybrid architecture of edge node + cloud platform is used:
[0115] The edge node is deployed locally in the equipment room, integrating a lightweight version of the fault thermal analysis module and a basic instruction execution unit of the dynamic handling execution module, for real-time collection of equipment data and execution of rapid blocking instructions;

Data interaction complies with OPC UA protocol, supports data encryption and breakpoint resume.
[0118] The system uses a hybrid architecture of edge node + cloud platform for deployment:
[0119] Edge node: Deployed in the control rooms and near the equipment of each production device in the park, the edge node integrates a lightweight version of the fault thermal analysis module and the basic instruction unit of the dynamic handling execution module. It directly accesses the sensor network of the field equipment, collects real-time operation parameters such as temperature, pressure, and flow, and can quickly perform simple fault blocking operations such as emergency valve shutdown and temporary suspension of local equipment operation, ensuring preliminary control at the initial stage of the fault.
[0120] Cloud platform: Deployed in the central control center of the park, it contains the complete functional modules of the system and has data analysis and processing capabilities. The cloud platform is responsible for processing large-scale device topology data, resource state data, and fault history data, completing tasks such as fault conduction thermal map drawing, full-path score calculation, and cross-regional resource feedback channel planning.
[0121] Data interaction mechanism: Edge nodes and cloud platforms interact through industrial Ethernet and wireless networks, using communication protocols that meet industrial standards, supporting data encryption and breakpoint resume. When the network state is good, edge nodes upload detailed data to the cloud for deep analysis and global optimization. When the network is abnormal or interrupted, edge nodes can rely on locally cached models and historical data to independently execute basic fault handling processes, ensuring the basic stability of the production process.
[0122] In specific implementation, device topology data: Extract the connection relationships and physical location information of all devices in the park from the device topology knowledge base, such as that reaction kettle A is connected to delivery pump B through a pipeline, and that the temperature sensor of reaction kettle A is connected to control system C through a cable. These connection relationships and relative positions provide a basic framework for analyzing possible fault conduction paths.
[0123] Resource pool state data: Collect real-time state of resource pool, including load of each computing node, inventory quantity and distribution location of different types of spare parts, bandwidth occupation of network link, etc. Mark the influence weight of different resources on fault conduction according to these data, such as that the support ability of a computing node with high load for fault analysis and processing decreases, and the inhibition effect on fault conduction weakens; while the area with sufficient spare parts inventory can obtain resource support faster during fault handling, reducing the risk of fault diffusion.
[0124] Fault prediction data: Receive real-time fault information sent by the fault prediction module, including fault type such as temperature anomaly and pressure fluctuation, initial device node, and fault trend prediction, etc. These information provide input for thermal value calculation and fault conduction analysis.
[0125] The fault heat analysis module uses a heat conduction simulation algorithm, combined with the above collected device topology, resource state and fault data, to calculate the fault heat value of each device node, and its calculation formula is:
[0126] wherein, is the fault heat value of node i, is the fault severity factor, is the resource influence factor, is the conduction coefficient, + + = 1, specifically the fault severity factor is determined according to the fault type and the degree of influence on production, for example, the severity of the abnormal temperature of the reaction kettle is higher than that of the slight leakage of the ordinary valve; the resource influence factor is related to the resource state around the node, the more abundant the resources, the lower the factor value, indicating that the inhibition of the resources on the fault conduction is stronger; the conduction coefficient reflects the coupling degree between the node and the fault source, the closer the connection and the more direct the influence, the larger the conduction coefficient value.
[0127] According to the calculated heat value of each node, a visual fault conduction heat map is generated, in which different colors represent different heat values, and the deeper the color, the more serious the degree of influence of the node by the fault and the higher the probability of fault conduction. Through the heat map, the operation and maintenance personnel can intuitively master the distribution and spread of the fault in the device topology, and provide a clear visual reference for subsequent blocking decisions.
[0128] The blocking point identification module evaluates the blocking value of each node by calculating the node blocking efficiency value, which is defined as: wherein, is the amount of total heat value in the fault conduction heat map after blocking node j, is the resource cost required to block the node, the module traverses all nodes in the device topology, and calculates the blocking efficiency value of each node one by one, for example, blocking a certain key valve node may greatly reduce the total heat value, but the resource cost required is also higher; while blocking a auxiliary monitoring node, the total heat value may decrease limitedly, but the resource cost is lower. Through calculation and comparison, each node is sorted from high to low according to the blocking efficiency value, and the nodes with high blocking value are preliminarily screened out as candidate key blocking nodes.
[0129] In order to more accurately locate the key blocking node, the module analyzes all possible fault conduction paths in the device topology, and calculates the score of each path, and the calculation formula of the path score is:
[0130] P is a certain conduction path in the device topology, the failure thermal value of the path node n, the resource cost of the blocking node n, traverse all possible conduction paths, calculate the score of each path, select the path with the highest score and the associated node as the candidate of the key blocking point, then perform blocking synergy verification on these candidate nodes, if multiple candidate nodes belong to a shorter path, combine them to evaluate the joint blocking effectiveness, the calculation formula is:
[0131] wherein, the resource input overlap degree between nodes, the overlap penalty coefficient, through this synergy verification, avoid duplication in resource input, ensure that resources can be used most reasonably, and finally determine multiple key blocking nodes.
[0132] The counter-feeding channel construction module analyzes the demand type and demand priority of various resources in the failure influence area according to the failure conduction thermal map, for example, the temperature abnormality of the reaction kettle in the failure influence area may require temperature control related spare parts and additional computing resources to support real-time temperature simulation and regulation; and the pump failure may require pump body spare parts and maintenance personnel resources.
[0133] Query the state data of the resource pool, find the available resources that match the demand of the failure influence area, and determine the location, type and quantity of these resources, based on the device topology relationship, use the shortest path algorithm and resource scheduling algorithm to plan the resource delivery path from the resource pool to the failure influence area, and the channel construction satisfies the following formula:
[0134] wherein the resource transmission delay of path node k, the resource transmission loss coefficient of path node k, by minimizing the weighted sum of transmission delay and loss, determine the optimal resource counter-feeding channel, ensure that resources can be delivered to where they are needed with the highest efficiency and the smallest loss, and provide timely resource support for fault handling.
[0135] The dynamic handling execution module analyzes the device type, current running state and carried business of each key blocking node, combined with the specific type of failure, formulates precise blocking instructions including resource injection strategy, business migration strategy and hardware restart / reset strategy, the instruction generation follows the principle of minimum business impact, the possible impact of the instruction is evaluated through the business impact degree evaluation model, the calculation formula is:
[0136] wherein, the business importance, For the duration of business interruption, To minimize the cost of business recovery, ensure that the business impact I after the instruction is executed is below a preset threshold, effectively blocking the transmission of faults while minimizing interference with normal production operations.
[0137] The module identifies the types of resources released during fault handling and takes corresponding recycling measures based on the resource type: if it is a computing resource, it injects it into a nearby overloaded node, updates the computing resource distribution in the resource pool, and triggers real-time updates to the fault heatmap; if it is a spare part resource, it returns it to the dynamic resource pool to replenish spare parts reserves and improve resource reuse rate; if it is a network bandwidth resource, it reroutes it to the fault area, adjusts the bandwidth allocation of the network topology, and optimizes the utilization of network resources. After all resource recycling operations are completed, the module calls the interface of the fault heatmap analysis module to update the fault propagation heatmap. Based on the changes in heatmap values before and after resource recycling and the resource input-output ratio, the module corrects the heatmap value calculation model to continuously improve the accuracy and adaptability of the model.
[0138] The machine learning training module collects relevant data on historical fault handling within the park, including fault types, selection of key blocking points, planning of resource feedback channels, and final handling effects, such as fault recovery time and business losses. This data is then organized, cleaned, and labeled to construct a training dataset, providing high-quality samples for model training.
[0139] With recovery time after fault handling, business interruption losses, and resource investment costs as optimization objectives, a reinforcement learning algorithm is used to train the critical blockage point location model and the resource feedback channel planning model. The objective function is:
[0140] in, For fault recovery time, For business interruption losses, Cost of resource investment + + = 1. Through continuous learning and iteration, the model parameters are optimized to improve the model's ability to plan key blocking points and resource feedback channels. The optimized model parameters are regularly updated to the blocking point identification module and the feedback channel construction module to achieve self-optimization of the algorithm. This enables the system to continuously adapt to changes in equipment status and business needs, and continuously improve the effectiveness of fault handling.
[0141] The data interaction module uses standardized data interfaces to communicate with external modules, ensuring the accuracy and compatibility of data transmission: When interacting with the fault prediction module, it receives fault prediction data encapsulated in a specific format, and data transmission follows the corresponding protocol to ensure real-time acquisition of accurate fault warning information; when interacting with the equipment topology knowledge base, it reads the equipment's 3D model data and connection relationship map through a specified interface, and performs data querying and updating to ensure the timeliness and accuracy of equipment topology information; when interacting with the resource pool status monitoring module, it acquires real-time resource status data, which is stored in a specific database format and synchronized through professional data acquisition tools to provide data support for resource scheduling and feedback channel planning. When outputting precise blocking instructions and resource recycling schemes to external systems, the instructions and schemes are encapsulated in a standard format and transmitted to the operation and maintenance execution terminal or upper-level management system through a secure protocol to ensure accurate and reliable information transmission and guide operation and maintenance personnel in actual fault handling operations.
[0142] The application of this system in chemical production parks has improved the response speed of fault handling. It can quickly locate key blocking nodes and plan resource feedback channels after a fault occurs, effectively curbing the spread of the fault. The efficiency of resource utilization has also been greatly improved, avoiding redundant investment and waste of resources. The system's self-optimization capability enables it to continuously adapt to changes in equipment and business within the park, continuously improving the accuracy and effectiveness of fault handling. At the same time, the collaborative working mode between edge nodes and the cloud platform ensures that the system can still maintain basic fault handling capabilities when network conditions are poor, providing a guarantee for the stable production of the park and reducing production interruption losses and resource consumption caused by faults.
