Description

Technical Field

[0001] This invention belongs to the field of nuclear power safety technology, specifically relating to a nuclear power plant inspection and management system. Background Technology

[0002] Nuclear power equipment inspections are crucial for ensuring the stable and normal operation of the equipment. Currently, nuclear power plant inspections are primarily conducted by inspectors using pen and paper. Inspectors rely on their experience to check, test, judge, and record the condition of each piece of equipment. This process is time-consuming, has a high error rate, uses a limited recording method, provides limited information, and often results in missed inspections. Problems discovered during inspections cannot be addressed promptly, paper inspection records are difficult to preserve, and historical inspection data cannot be effectively utilized.

[0003] Although some nuclear power companies use handheld terminals for inspections, they only record data without further data analysis and processing. The data obtained from the inspections cannot be uploaded in a timely manner, making it difficult for management to understand sudden major events in a timely manner. There is a lack of on-site data extraction and analysis, resulting in a certain lag in emergency response. Summary of the Invention

[0004] The purpose of this invention is to provide a nuclear power room inspection and management system that can solve the problems of long inspection time, high error rate, single recording method, limited information content, and certain lag in emergency response in traditional power room inspections.

[0005] The technical solution of the present invention is as follows: a nuclear power room inspection and management system, including an equipment monitoring subsystem, a power and environment monitoring subsystem, a video monitoring subsystem, an operation and maintenance management subsystem, and an electronic inspection subsystem;

[0006] The equipment monitoring subsystem collects equipment status information, alarm information, and fault information from broadcast alarms, internal intercoms, data transmission, and the clock system, and transmits them to the operation and maintenance management subsystem.

[0007] Power and environmental monitoring subsystem; collects temperature, humidity, water immersion, access control, air conditioning, and UPS data and transmits them to the operation and maintenance management subsystem;

[0008] The video surveillance subsystem collects image information and aggregates it into the operation and maintenance management subsystem;

[0009] The operation and maintenance management subsystem processes the data collected by the equipment monitoring subsystem, power and environmental monitoring subsystem, and video monitoring subsystem in a unified manner to generate corresponding tasks, execution parameters, and execution nodes. The electronic inspection subsystem executes the corresponding tasks according to the tasks issued by the operation and maintenance management system.

[0010] The equipment monitoring subsystem monitors various devices in the computer room in real time, and collects and analyzes equipment operation data to detect equipment failures and performance degradation, ensuring the stable and safe operation of the equipment. The equipment monitoring subsystem monitors the following business subsystems: broadcasting, sound alarms, clocks, intercoms, video surveillance, telephones, video conferencing, maritime satellite, dispatch telephones, SMS platforms, access control, LEDs, audio and video systems, and structured cabling.

[0011] The equipment monitoring subsystem uses the Internet of Things (IoT) to collect and transmit data from various devices in the computer room to the Internet in real time. It collects and analyzes real-time data from various devices in the computer room and feeds back the analysis results to the user's computer or mobile phone in real time. It allows for remote monitoring and management of various devices in the computer room anytime and anywhere, and can promptly detect and resolve various faults and problems. Various faults and problems are notified to maintenance personnel in the form of alarms, and maintenance personnel issue maintenance tasks based on the alarm faults for handling.

[0012] The device monitoring subsystem remotely collects and receives device faults via an IoT gateway based on RS485, RS232, Bluetooth, Zigbee protocols or MQ message queues, and summarizes, classifies, and displays the faults and alarm types.

The computer room power mainly includes single-phase electricity, three-phase electricity, UPS, and storage batteries; the computer room environment mainly includes temperature and humidity, water immersion, air conditioning, and access control.

[0014] The video surveillance subsystem labels images and classifies faults in the equipment according to type to establish a fault type dataset. Then, it selects the YOLOv5 model, pre-trains it using the COCO dataset, and then trains the YOLOv5 model using the fault dataset. Finally, after training, the model is evaluated by calculating mAP, Recall, and Precision metrics to assess the model's accuracy.

[0015] The aforementioned operation and maintenance management subsystem collects alarm information, operation and maintenance information, and fault information from various front-end devices, summarizes and centrally processes the data, and includes the following modules: alarm management module, fault management module, and maintenance management module.

[0016] The nuclear power room inspection and management system uses the alarm management module for real-time monitoring and linkage with the power environment monitoring subsystem to centrally manage alarms for various subsystems and operating equipment in the power room. It features hierarchical display of alarms and functions such as audible and visual alarm reminders, alarm record statistics and queries, alarm data analysis, alarm location, and printing. It also includes equipment ledgers, spare parts, and document management.

[0017] The fault management module establishes a fault management log, which includes equipment maintenance personnel, maintenance time, cause of fault, and photos of the equipment before and after the handling.

[0018] The maintenance management module establishes a maintenance database to manage and access information on core equipment failure handling and spare parts availability.

[0019] The beneficial effects of this invention are as follows: By employing image recognition methods, it enables inspection work in areas inaccessible to personnel or with limited inspection space. It allows for timely and accurate understanding of alarm information throughout the computer room for easier handling, enabling early fault detection and allowing for rapid isolation of problems, thus ensuring the reliability of system equipment.

[0020] Figure 1 This is a diagram of the nuclear power room inspection and management system architecture provided by the present invention. Detailed Implementation

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] The nuclear power room inspection management system and method provided by this invention are based on an advanced network management model and a hardware and software solution. It adopts event correlation and anomaly handling as the basic technology platform. In addition to monitoring the basic room environment and power, it also implements centralized fault management for communication systems such as broadcasting, audible alarms, intercoms, and clocks, as well as professional networks such as switching, transmission, data, and power supply of equipment from different manufacturers. At the same time, it realizes the correlation between alarms and responsible personnel, and interfaces with the fault ticket management system to promptly transmit alarm information to maintenance personnel, record fault tracking and handling tickets, and help maintenance personnel improve equipment and business management level.

[0023] The nuclear power room inspection and management system collects the operating status of each monitored object and transmits it to the dedicated network of the inspection system. Maintenance personnel can view the specific equipment operating data and fault information in real time. At the same time, the system has functions such as video linkage and SMS linkage to assist maintenance personnel in completing daily inspection and fault diagnosis work, and ensure the safe and reliable operation of the communication room.

[0024] Equipment faults are categorized by type, and a fault type image library is established. Image recognition methods are used to analyze and compare collected equipment images to determine the fault condition. This data is then reflected in the management system, enabling maintenance personnel to promptly and accurately understand alarm information across the entire computer room for timely handling. This facilitates early fault detection, allowing for rapid problem isolation and ensuring system equipment reliability. A fault management log is established, including information such as equipment maintenance personnel, maintenance time, fault cause, and before-and-after photos of the equipment. This log provides preliminary analysis and judgment when faults occur, facilitating rapid fault handling by maintenance personnel.

[0025] By combining QR codes and RFID tags, intelligent identification is achieved. During on-site inspections, the inspection terminal equipment automatically records the inspection time and automatically opens the task requirements and inspection item list corresponding to the tag device through QR code or RFID scanning identification devices.

[0026] Data collected through image recognition and terminal devices is uploaded to the inspection management system for data analysis. The data view of the inspection management system can present the status of various indicators of the equipment in different chart forms, which facilitates monitoring of equipment operation from a macro perspective, automatically generating defect reports, and providing maintenance assistance decisions by combining historical fault data.

Faults and problems are alerted to maintenance personnel, who then issue maintenance tasks based on the alerts. Intelligent analysis technology utilizes various intelligent algorithms and data analysis techniques to deeply analyze and predict data from various devices in the data center, facilitating timely problem detection and resolution.

[0038] The system monitors environmental parameters such as temperature, humidity, water leakage, and fire prevention for the working environment of power equipment and power transmission and transformation equipment. It also monitors the air conditioning in the computer room and connects to the power environment monitoring system to achieve real-time data monitoring, alarm threshold setting, alarm prediction, and takes corresponding handling strategies in conjunction with emergency plans to ensure that the working environment is in a healthy state and provide strong support for the reliable operation of the equipment.

[0039] The video surveillance subsystem, through video images, can comprehensively monitor the operation of the computer room, improve security, avoid human errors such as missed detections and false detections, and enhance the level of operation and maintenance management. Through a remote monitoring and automatic early warning system, it can replace manual labor for large-scale, uninterrupted monitoring of computer room equipment, featuring cost-effectiveness, simplicity, convenient maintenance, and flexible configuration. Simultaneously, by annotating images and classifying equipment faults according to type, a fault type dataset is established. Then, a YOLOv5 model with high algorithm accuracy and speed is selected, pre-trained using the COCO dataset, and then trained on the fault dataset. Finally, after training, the model is evaluated by calculating metrics such as mAP, Recall, and Precision to assess its accuracy.
