Description

Technical Field

[0001] The present invention relates to the technical field of safety inspection, and more particularly to an integrated safety inspection method and system for a nuclear power plant. Background Art

[0002] Nuclear power plant security requires comprehensive inspections of vehicles entering and exiting various areas of the plant. These inspections include ensuring that the driver has permission to enter the designated area, that the vehicle has a valid and registered permit, whether the vehicle's nuclear radiation level exceeds permitted levels (which could indicate the illegal carrying of radioactive materials), whether illegal personnel are hiding under the vehicle, whether prohibited items are loaded inside the vehicle, and whether illegal items are hidden in key areas such as the cab, mailbox, and roof compartment. Current nuclear power plant practices rely on manual inspections of the cab, visually verifying the presence of illegal personnel or items. These inspections typically use paper receipts with handwritten vehicle passage times. This method fails to provide comprehensive vehicle inspections, creating effective records of vehicle passage and inspections, and hinders tracing back issues. Furthermore, manual inspections rely entirely on the security personnel's commitment and personal expertise, making it prone to oversights that could allow threats to enter key areas of the plant.

They should be regarded as exemplary and their purpose is only to illustrate the feasibility of implementing the technical solution of this application, but it does not mean that the applicant has or will necessarily use the solution.

[0054] In order to solve the technical problems existing in the existing nuclear power plant safety inspection scheme, the present invention provides an integrated safety inspection method for a nuclear power plant.

[0055] Figure 1 4 is a flow chart of an integrated safety inspection method for a nuclear power plant according to an embodiment of the present invention.

[0056] like Figure 1 As shown, the above-mentioned integrated safety inspection method for a nuclear power plant includes operations S110 to S150.

[0057] In operation S110 , the license plate information and driver information of the target vehicle are authenticated. If the authentication result indicates a pass, a safety inspection procedure for the target vehicle is initiated.

[0058] The above operation S110 involves the authority verification operation at the entrance of the nuclear power plant. The safety inspection procedure for the target vehicle will be started only after the authority verification result shows that the target vehicle and the driver both have the authority to pass through the nuclear power plant. If one of the target vehicle or the driver does not have the authority to communicate with the nuclear power plant, the target vehicle and the driver will be denied access to the nuclear power plant, and the operation prompt subsystem will prompt the target vehicle or driver that they do not have the authority and notify them to leave the entrance of the nuclear power plant as soon as possible.

[0059] In an embodiment of the present invention, before obtaining the driver's information, the driver's consent or authorization can be obtained. Only after the driver's consent is obtained can the driver's personal information be obtained and used for permission verification operations.

[0060] In operation S120 , a real-time nuclear radiation detection is performed on the target vehicle. When the nuclear radiation detection value indicates that the detection value is within a safe range, a scanning operation on the target vehicle is initiated.

[0061] After the target vehicle and driver have the permission to pass through the nuclear power plant, the target vehicle is allowed to enter the inspection channel of the nuclear power plant and undergoes nuclear radiation testing to check whether the nuclear radiation value of the target vehicle is within the safe value range. If it exceeds the safe value, an alarm signal is issued through the operation prompt subsystem and the subsequent safety inspection procedures are terminated.

[0062] In operation S130 , in response to the scanning operation, a full vehicle scan is performed on the chassis of the target vehicle to obtain a vehicle bottom scan image.

[0063] In operation S140 , in response to the scanning operation, multi-dimensional perspective imaging and backscattered imaging are performed on the target vehicle to obtain a perspective image and a backscattered image.

[0064] In the above operations S130 and S140, when the nuclear radiation detection value is within the safe value range, a multi-dimensional and all-round scan of the target vehicle is performed to detect whether the target vehicle carries any abnormal items.

[0065] In operation S150 , an abnormal object entrainment analysis is performed on the target vehicle based on the vehicle bottom scanning image, the perspective image, and the backscattered image. If the analysis result indicates that the target vehicle does not carry any abnormal object, the safety inspection procedure for the target vehicle is terminated.

[0066] In an embodiment of the present invention, a corresponding operation interface can be provided for the driver to choose to agree or reject the automated decision result. That is, before the intelligent analysis and processing / decision-making process is performed on the driver and vehicle information, an instruction to agree or reject the processing / decision-making process can be obtained from the driver through the corresponding operation interface. If the driver agrees to the processing / decision-making process, the intelligent analysis and processing / decision-making process is performed on the driver information, that is, step S150 is executed. If the driver rejects the processing / decision-making process, the expert decision-making process is entered.

[0067] According to an embodiment of the present invention, the above-mentioned integrated security inspection method for nuclear power plants also includes: using the information collected from the target vehicle during the security inspection procedure and the generated image data to form vehicle electronic pass inspection record data with the license plate information of the target vehicle as the index, and saving the vehicle electronic pass inspection record data into a database.

[0068] Intelligent image analysis is used to determine if any unusual objects are present on the roof, underbody, interior, or in the interlayers between surfaces. Inspectors can then use real-time video images and, combined with the collision information, determine whether the vehicle can pass. If no unusual objects are found, the inspector issues a release order for the target vehicle, allowing it to exit the nuclear power plant's inspection corridor. The inspection information is then linked to the vehicle's license plate number and stored electronically.

[0069] The integrated security inspection method for nuclear power plants provided by the present invention verifies the authority of the license plate information and driver information of the target vehicle, and through nuclear radiation detection and multi-dimensional scanning of the target vehicle, realizes multi-round, multi-dimensional and comprehensive security inspections of the target vehicles entering the nuclear power plant, greatly reducing the risk of missed inspections; at the same time, through the non-invasive full-vehicle scanning operation mode, not only can the detection of abnormal objects carried by the target vehicle be completed fully automatically, but also no human intervention is required, which greatly reduces costs and avoids the risk of relevant personnel being scanned by radiation.

[0070] According to an embodiment of the present invention, the above-mentioned authorization verification of the vehicle information and driver information of the target vehicle is performed, and when the authorization verification result indicates that it has passed, the safety inspection procedure for the target vehicle is started, including: collecting the facial information, access card information and password information corresponding to the access card information of the driver of the target vehicle; collecting the license plate information of the target vehicle; comparing the facial information, access card information, password information and license plate information with the corresponding information in the background database one by one to obtain the authorization verification result; when the authorization verification result indicates that it has passed, the state of the entrance interception device is converted to a release state so that the target vehicle is released to the inspection channel of the nuclear power plant, and the safety inspection procedure for the target vehicle is started.

[0071] According to an embodiment of the present invention, the above-mentioned real-time nuclear radiation detection of the target vehicle, when the nuclear radiation detection value is represented as being within a safe value range, initiating a scanning operation on the target vehicle includes: when the nuclear radiation detection value is represented as being within a safe value range, real-time position detection of the target vehicle and checking the driver status of the target vehicle; when the target vehicle is located at a designated scanning position and the driver of the target vehicle is located at a designated waiting position, initiating a scanning operation on the target vehicle.

[0072] According to an embodiment of the present invention, the above-mentioned inspection of the driver status of the target vehicle includes: continuously detecting the vehicle pass in the cab of the target vehicle and capturing the face of the person in the designated waiting position, and performing multi-dimensional judgment on the driver status in the cab through the vehicle pass and the captured facial image; when the multi-dimensional judgment result indicates that the driver has not left the cab, the driver is prompted to leave the cab through multiple types of notification methods.

[0073] The integrated safety inspection method for nuclear power plants provided by the present invention will be further described in detail below through specific embodiments.

[0074] When the target vehicle arrives at the entrance of the nuclear power plant inspection channel, the driver gets off the vehicle to collect facial images, access card information and password information; after sensing that the target vehicle has arrived at the designated location, the license plate information capture device is activated to obtain the license plate information.

[0075] The collected facial image, access card information, password information, and vehicle information are used for permission verification. If the verification fails, the driver will be notified that they do not have access rights and the security check process ends. If the verification passes, the subsequent security check process will be carried out.

[0076] The first sliding door opens automatically. After the vehicle enters the inspection channel, the first sliding door closes and the vehicle security inspection process starts.

[0077] After the inspection process is initiated, the nuclear radiation monitoring system monitors the value and alarm signals in real time. The process ends when the nuclear radiation exceeds the limit alarm signal is received. If the nuclear radiation monitoring is normal, the subsequent steps will be continued.

[0078] The vehicle drives to the designated location in the channel and stops, displays the information of the inspected vehicle and driver, and prompts the driver to leave the cab and wait at the designated location through voice and text.

[0079] The system continuously checks the vehicle pass in the cab and determines whether the driver has left the cab and is waiting at the designated location. It captures the face of the person at the designated location and compares it with the driver's face in the previous step. A multi-dimensional assessment is then made based on whether the face is detected in the cab. The entire inspection process is recorded. If the driver fails to comply, repeated reminders are given. If the above conditions are met, the system proceeds to the next step.

[0080] The vehicle underbody scanning subsystem is activated to scan the entire vehicle chassis, capturing scanned and video images. Simultaneously, the vehicle multi-dimensional scanning subsystem is activated to automatically perform perspective and backscattered imaging of the vehicle's two sides, roof, and interior from back to front along the planned route, capturing both perspective and backscattered scan images. The data, images, and videos collected during the inspection are then centrally displayed in real time.

[0081] Intelligent image analysis detects any unusual objects on the roof, underbody, interior, or between surfaces. Inspectors then use real-time video and collision verification information to determine if the vehicle is passable. If not, the operator's notification subsystem issues a notification, concluding the process. If passable, the operator proceeds to the next step.

[0082] The vehicle exits the inspection channel after a release is issued to the access control and interception subsystem, which lowers the bollards and opens the second sliding door. All inspection information, linked to the license plate number, is electronically recorded and stored, completing the inspection process.

[0083] According to a second aspect of the present invention, an integrated security inspection system for a nuclear power plant is provided, comprising: an authority verification subsystem for performing authority verification on the license plate information and driver information of a target vehicle, and starting a safety inspection procedure for the target vehicle when the authority verification result indicates that the vehicle has passed; a nuclear radiation monitoring subsystem for performing real-time nuclear radiation detection on the target vehicle, and starting a scanning operation on the target vehicle when the nuclear radiation detection value indicates that the vehicle is within a safe value range; a vehicle bottom scanning subsystem for performing a full vehicle scan on the chassis of the target vehicle in response to the scanning operation to obtain a vehicle bottom scanning image; a vehicle multi-dimensional scanning subsystem for performing multi-dimensional perspective imaging and backscatter imaging on the target vehicle in response to the scanning operation to obtain a perspective image and a backscatter image; an information display subsystem for performing abnormal object entrainment analysis on the target vehicle based on the vehicle bottom scanning image, the perspective image and the backscatter image, and ending the safety inspection procedure on the target vehicle when the analysis result indicates that the target vehicle is not entrained with abnormal objects.

[0084] According to an embodiment of the present invention, the above-mentioned integrated security inspection system of a nuclear power plant also includes: a driver information collection subsystem, a vehicle information collection subsystem, a video collection and analysis subsystem, a channel control and interception subsystem, and an operation prompt subsystem; wherein, the driver information collection subsystem and the vehicle information collection subsystem are arranged at the entrance end of the inspection channel of the nuclear power plant; wherein, the video collection and analysis subsystem is arranged at the entrance end and exit end of the inspection channel of the nuclear power plant, and the channel control and interception subsystem is arranged at the entrance end and exit end of the inspection channel of the nuclear power plant; wherein, the underbody scanning subsystem is arranged in the inspection channel of the nuclear power plant, the vehicle multi-dimensional scanning subsystem is arranged to be able to slide along the inspection channel of the nuclear power plant, the nuclear radiation monitoring subsystem is arranged on both sides of the inspection channel of the nuclear power plant, and the operation prompt subsystem is arranged at the exit end of the inspection channel of the nuclear power plant; wherein, the authority verification subsystem and the information display subsystem are arranged at the inspection booth.

[0085] According to an embodiment of the present invention, the above-mentioned driver information collection subsystem includes a card reader and a face recognition unit, and the driver information collection subsystem is used to collect the driver's facial image, access card information and password information corresponding to the access card information; wherein, the vehicle information collection subsystem includes a license plate capture camera, a fill light, an infrared counter-radiation sensor device, a ground sensing coil and a vehicle channel gear lever, and the vehicle information collection subsystem is used to collect the license plate information of the target vehicle when the ground sensing coil senses that the target vehicle passes and the infrared counter-radiation sensor device is blocked, and the fill light is used to provide light compensation.

[0086] According to an embodiment of the present invention, the video acquisition and analysis subsystem includes multiple cameras and an image analysis unit, which displays captured vehicle and driver images in real time on the information display subsystem. The passage control and interception subsystem includes double-layer sliding doors, lifting bollards, or other anti-collision devices. The operation prompt subsystem includes a display screen, an audible and visual alarm, and a figure player, and is used to provide information prompts to the driver and issue warnings to safety inspectors.

[0087] According to an embodiment of the present invention, the above-mentioned authority verification subsystem is also used to display the result of the authority verification in real time on the information display subsystem; wherein, the under-vehicle scanning subsystem is also used to display the under-vehicle scanning image in real time on the information display subsystem, and the under-vehicle scanning subsystem includes an intelligent mobile scanning robot and / or a high-speed snapshot camera; wherein, the information display subsystem is also used to display the images and information collected during the security inspection process to the security inspectors in real time, and save the received information and image data in the database with the license plate information as the index.

[0088] The following is a detailed description of the embodiments and the attached Figure 2 The integrated safety inspection system for nuclear power plants provided by the present invention is described in further detail.

[0089] Figure 2 2 is a schematic diagram of the deployment of an integrated safety inspection system for a nuclear power plant according to an embodiment of the present invention.

[0090] like Figure 2 As shown, the integrated security inspection system for nuclear power plants provided by the present invention includes a driver information collection subsystem (11), a vehicle information collection subsystem (12), a video collection and analysis subsystem (13), a vehicle bottom scanning subsystem (14), a vehicle multi-dimensional scanning subsystem (15), a channel control and interception subsystem (16), a nuclear radiation monitoring subsystem (17), an operation prompt subsystem (18), an authority verification subsystem (19), and an information display subsystem (20).

[0091] like Figure 2 As shown, the driver information collection subsystem (11) is deployed at the outermost side of the channel and is used to collect the vehicle driver's facial information, access card and password information, and transmit the collected information to the authority verification subsystem (19) and the information display subsystem (20).

[0092] The driver information collection subsystem (11) is composed of a card reader and a facial recognition camera. The driver of a passing vehicle needs to take a photo to capture his or her facial image, swipe the access card on the card reader, and enter the password. The above facial information, card information, and authorization password information are collected and transmitted to the background permission verification subsystem (19) for comparison and verification. When all the driver's information passes the verification, the vehicle security inspection process is triggered.

[0093] like Figure 2 As shown, the vehicle information collection subsystem (12) is deployed on the side of the channel close to the entrance, and is used to sense vehicles and collect vehicle license plate information, and transmit the collected information to the authority verification subsystem and the information display subsystem.

[0094] The vehicle information collection subsystem (12) consists of a license plate capture camera, a fill light, an infrared beam sensor, a ground sensor coil, and a channel barrier. When the inspection process begins, the ground sensor coil senses that a vehicle has passed and the infrared beam sensor is blocked by the vehicle, which triggers the license plate capture camera to capture the vehicle license plate. The fill light provides light compensation, and the license plate information is transmitted to the background permission verification subsystem (19) for verification to verify whether the vehicle has the permission to pass through this area.

[0095] like Figure 2 As shown, the video acquisition and analysis subsystem (13) consists of multiple video cameras deployed in front and behind the vehicle channel and a background analysis module. After the vehicle inspection process is triggered, the video camera records the entire vehicle inspection process and displays the real-time video image in the information display subsystem (20) to help the inspection personnel make auxiliary judgments. After the inspection process is started, video analysis is used to check whether there is a vehicle to be inspected in the channel. The video stream of the video camera directly in front of the vehicle is connected to the background analysis module in real time for intelligent analysis of the unified format pass posted on the vehicle cab and whether there is a driver in the cab. The analysis results are transmitted to the information display subsystem (19) and used as the judgment condition for whether to start the full vehicle scan.

[0096] like Figure 2 As shown, the vehicle bottom scanning subsystem (14) is deployed on the ground in the middle of the inspection channel. The vehicle bottom scanning subsystem (14) can use intelligent mobile scanning robots or high-speed snapshot cameras and other equipment to send back high-definition images and real-time video information of the entire vehicle bottom in real time. After the full vehicle scan is started, the vehicle bottom scanning imaging can be automatically completed and the images and videos can be transmitted to the information display subsystem (20).

[0097] like Figure 2 As shown, the vehicle multi-dimensional scanning subsystem (15) can move forward and backward autonomously according to instructions along a fixed route within the inspection channel.

[0098] The vehicle multi-dimensional scanning subsystem (15) is responsible for forming a side perspective image, a side backscattered image, a top backscattered image, a top perspective image, or a combination of the above perspective and backscattered images through projection imaging and backscattered imaging, and inspecting the interior of the vehicle body, the interior of the cab, the surface of the vehicle body, and the surface of the roof from multiple dimensions. After the full vehicle scanning process is started, the vehicle multi-dimensional scanning subsystem (15) can move along the planned path, generate scan images in real time, and mark abnormal areas in the image to assist the inspector in focusing on the inspection.

[0099] like Figure 2 As shown, the channel control interception subsystem (16) is deployed at the channel entrance and exit to control vehicles entering and leaving the channel and prevent vehicles from passing illegally.

[0100] The channel control and interception subsystem (16) consists of a double-layer sliding door, a lifting column or an anti-collision device. When the driver's identity verification is passed, the first sliding door opens to allow the vehicle to enter the inspection channel. When the vehicle enters the inspection channel, the first sliding door closes. When the entire inspection process is completed and the inspection results are normal and the vehicle is allowed to pass, the lifting column or anti-collision device falls and the second sliding door opens. After the vehicle exits the channel, the second sliding door and the lifting column or anti-collision device automatically rise. The entire channel control process can be automatically controlled by the system or manually controlled by the inspection staff.

[0101] like Figure 2 As shown, the nuclear radiation monitoring subsystem (17) is deployed on both sides of the center of the channel to monitor the nuclear radiation value of the vehicle after the vehicle enters the channel and determine whether it exceeds the limit.

[0102] The nuclear radiation monitoring subsystem (17) starts monitoring and outputting nuclear radiation values ​​after the vehicle inspection process is started. The real-time data and alarm signals are transmitted to the information display subsystem (20).

[0103] like Figure 2 As shown, the operation prompt subsystem (18) is deployed at one end of the channel to display relevant information of the inspected vehicle and to provide process step prompts to the vehicle driver.

[0104] The operation prompt subsystem (18) is composed of an LED display screen, an audible and visual alarm, and a sound player, and is used to display license plate information, pass information, and driver information. At the same time, it can cooperate with the sound player to provide process information prompts to the driver of the inspected vehicle. When an abnormal inspection situation occurs, the audible and visual alarm can be used to prompt the inspection personnel to issue an alarm message.

[0105] like Figure 2 As shown, the background server of the authority verification subsystem (19) is deployed in the computer room.

[0106] The authority verification subsystem (19) receives the driver's face, access card and password information, and license plate information transmitted by the driver and vehicle information collection system, and compares them with the background database to verify whether the driver and vehicle have the right to pass through the target area, and feeds back the verification results to the information display subsystem (20).

[0107] like Figure 2 As shown, the background server of the information display subsystem (20) is deployed in the computer room.

[0108] The information display subsystem (20) receives the collected information, verification information, scanned image information, radiation monitoring data, vehicle bottom scan images and video recordings from the above subsystems, forms a data string indexed by the vehicle license plate and saves it as vehicle electronic pass inspection record data. At the same time, the above information can be displayed on the computer screen for inspection personnel to observe. During the vehicle inspection process, according to the current process status, the operation prompt subsystem is driven to provide text and voice prompts, and finally the vehicle is released through the channel control and interception subsystem (16), so that the entire inspection operation forms a closed loop.

[0109] The integrated nuclear power plant security inspection system provided by this invention conducts comprehensive vehicle inspections across multiple dimensions, including driver information, vehicle information, and radiation monitoring systems. The entire vehicle (underbody, roof, interior, and interlayer) is scanned and imaged non-invasively and fully automatically, eliminating the need for human intervention. This system also enables unmanned operation and remote inspection and release, saving personnel and generating electronic inspection records for traceability and retrospective review. Furthermore, intelligent video analysis determines whether the driver has exited the vehicle and whether anyone is inside the cab, preventing radiation exposure.
