[0078] Figure 3 It is a flow chart of a method for monitoring foreign matter intrusion in a nuclear power plant proposed in another embodiment of the present disclosure.

[0079] like Figure 3 As shown, the foreign body intrusion monitoring method for a nuclear power plant includes:

[0080] S301: Obtaining RFID signal detection results of corresponding incoming items and RFID signal detection results of outgoing items of the nuclear power plant, wherein the corresponding incoming items of the nuclear power plant are configured with corresponding RFID tags.

[0081] Among them, incoming items may refer to items brought into a nuclear power plant during a certain operation, while outgoing items may refer to items taken away from a nuclear power plant during an operation.

[0082] In the disclosed embodiment, when the RFID signal detection results of the corresponding incoming items and the RFID signal detection results of the outgoing items of the nuclear power plant are obtained, real-time automatic detection of the incoming and outgoing items of the nuclear power plant can be achieved.

[0083] S302: Determine the inventory information of the incoming items based on the RFID signal detection results of the incoming items.

[0084] Among them, the incoming items inventory information can be used to indicate the list of incoming items.

[0085] In the disclosed embodiment, the inventory information of incoming items may include item type, entry time, etc., and there is no limitation on this.

[0094] Figure 4 It is a flow chart of a method for monitoring foreign matter intrusion in a nuclear power plant proposed in another embodiment of the present disclosure.

[0095] like Figure 4 As shown, the foreign body intrusion monitoring method for a nuclear power plant includes:

[0096] S401: Acquire real-time monitoring data of a target area.

[0097] Among them, real-time monitoring data refers to the video data of the target area obtained by high-definition video monitoring equipment.

[0098] That is, in the disclosed embodiment, high-definition video surveillance equipment may be configured in a nuclear power plant to obtain real-time monitoring data of a target area, thereby providing reliable data support for the subsequent construction of an electronic fence corresponding to the target area.

[0099] S402: Building an electronic fence corresponding to the target area based on the real-time monitoring data.

[0100] Among them, electronic fence refers to a security system that integrates video surveillance and intelligent recognition technology, which can monitor the activities within the fence area in real time in combination with the video surveillance system. Once there is an illegal intrusion or abnormal behavior (such as foreign object intrusion, etc.), the system will immediately trigger an alarm.

[0101] S403: When a foreign object is detected entering the electronic fence, a foreign object intrusion alarm message is generated.

[0102] That is to say, in the embodiment of the present disclosure, while foreign body intrusion monitoring is performed based on three-dimensional point cloud data and image data, foreign body intrusion monitoring can also be performed based on real-time monitoring data of the target area.

[0103] In this embodiment, by acquiring real-time monitoring data of the target area, an electronic fence corresponding to the target area is constructed based on the real-time monitoring data, and when a foreign object is detected to enter the electronic fence, a foreign object intrusion alarm message is generated. Thus, real-time foreign object intrusion monitoring of the target area can be achieved based on the real-time monitoring data, thereby effectively improving the robustness of the foreign object intrusion monitoring method of the nuclear power plant.

[0104] Based on the above embodiments, the foreign body intrusion monitoring method for a nuclear power plant proposed in the present disclosure can be implemented by a foreign body intrusion monitoring system for a nuclear power plant, such as Figure 5 As shown, Figure 5 This is a schematic diagram of the structure of the foreign body intrusion monitoring system for nuclear power plants proposed in the present disclosure. The system can be composed of the following parts:

[0105] Item counting system: It can prevent foreign objects from intruding. At the beginning of the inspection, the incoming items are counted and classified, RFID tags are attached to the temporary incoming items, and images of people and objects are saved and weighed with high precision. When the inspection is completed, the items are counted again. Through comparative analysis, it can be checked whether any items are missing, and relevant information of the missing items can be provided.

[0106] 3D LiDAR monitoring module: By continuously scanning the key areas of the nuclear power plant (i.e. the target areas mentioned above), a three-dimensional space dot matrix is ​​constructed in real time. LiDAR has the characteristics of high precision, high resolution and fast response, and can keenly capture any tiny movement of objects and spatial changes. Once an abnormal dot matrix distribution is detected, it can be preliminarily judged that there may be foreign body intrusion.

[0107] HD video surveillance module: works in conjunction with the laser radar monitoring module. When the laser radar detects suspected foreign objects intruding, it immediately triggers the HD video surveillance system to collect and analyze HD images of the abnormal area. With its excellent image clarity and color reproduction capabilities, the HD video surveillance system can accurately identify the type, shape, size and other characteristics of foreign objects, greatly increasing the speed of identifying and judging the type of foreign objects. The video information of the alarm time period is automatically reported to the management background for manual inspection of the details of the foreign objects. At the same time, restricted areas can be demarcated and electronic fences can be set up. When objects enter the restricted area, an alarm signal can also be issued. It serves as a backup with the radar monitoring system to improve the accuracy and reliability of monitoring. When the electromagnetic environment of the environmental noise meter meets the requirements, noise detectors and microwave detectors can be added for multi-dimensional detection.

[0108] Data Processing and Analysis Center: Responsible for receiving and integrating data from LiDAR and HD video surveillance modules. Using advanced algorithms and models, the center conducts in-depth analysis and processing of data to accurately determine the intrusion of foreign objects and assess the risks they may bring.

[0109] Alarm and response system: Once the data processing and analysis center confirms the foreign body intrusion event, the alarm device will be immediately activated, including sound and light alarm, SMS notification module, etc., to send detailed alarm information to relevant personnel. At the same time, according to the type of foreign body and risk assessment results, it provides a strong basis for formulating effective treatment plans.

[0110] Database and storage module: used to store various data in the monitoring process, including laser radar dot matrix data, high-definition video images, analysis results and alarm records, etc. These data are not only helpful for post-accident tracing and cause analysis, but also provide important basis for system optimization and improvement.

[0111] The innovative nuclear power plant foreign body intrusion monitoring system proposed in the present disclosure, at its core, is a detection method that integrates laser radar and high-definition video (noise or microwave detectors can be added in some scenarios) to achieve comprehensive, accurate, and real-time monitoring of nuclear power plants, ensuring that foreign body intrusion is discovered in a timely manner and that corresponding measures are taken. It can also effectively shorten the downtime and reactor downtime caused by the search for foreign bodies after foreign body intrusion occurs, so it has a very huge economic value. This monitoring system is applicable to multiple key areas of nuclear power plants, such as reactor buildings, fuel storage areas, cooling systems, electrical equipment rooms, etc. Whether during normal operation or during special periods such as equipment overhaul and maintenance, it can provide reliable protection for the safety of nuclear power plants. It can also be promoted in various nuclear power plants and has broad market prospects.
