Description

Technical Field

[0001] The present invention belongs to the technical field of hazard identification management, and in particular relates to a hazard zone identification management system and method based on nuclear emergency events. Background Art

[0002] In the current emergency response system for nuclear, radiological, or chemical incidents, the rapid identification and effective management of hazardous areas are critical. Existing technical solutions primarily use signs carried by personnel or transported by vehicles to mark hazardous areas. While these signs can indicate the level of danger to a certain extent, they suffer from numerous shortcomings. First, traditional signs lack explosion-proof and chemical-proof properties and are easily damaged in extreme environments, compromising their effectiveness. Second, updating sign information relies on manual operation, which is inefficient and makes it difficult to ensure real-time information. Furthermore, the lack of a unified information sharing platform results in poor information transfer between departments, limiting the speed of emergency response.

[0003] Therefore, the present invention provides a dangerous area identification management system and method based on nuclear emergency events, which can improve the management efficiency and safety of dangerous areas by intelligent and automated means. Summary of the Invention

[0004] The present invention provides a hazardous area identification management system and method based on nuclear and chemical emergencies, which is used to solve the technical problems of the existing hazardous area identification management system lacking explosion-proof and chemical-proof characteristics, relying on manual labor for identification information, low efficiency, and lacking a unified information sharing platform.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is as follows: a dangerous area identification management system based on nuclear emergency events, the system includes a dangerous area division mark, a target tracker, a wireless communication module and information sharing software, the dangerous area division mark is provided with a target tracker, a wireless communication module and a light-emitting device, the dangerous area division mark adopts a tumbler shape and an integrated light-emitting device, which can facilitate on-site personnel to quickly identify the danger level, the target tracker has a built-in target positioning algorithm, once it is turned on, it automatically reports its precise location, determines the dangerous area and the current danger level information to the information sharing software, the information sharing software is responsible for receiving and integrating data from the dangerous area division mark to form a unified dangerous area map, the map can display the location, size and danger level of each dangerous area in real time, so that the emergency command center can grasp the location information of each dangerous area in real time, providing strong support for subsequent emergency response.

[0006] Furthermore, the light-emitting device adopts an energy-saving LED light source, and distinguishes different danger levels through red, yellow and green lights. Red represents high danger, yellow represents medium danger, and green represents safe or low-risk areas.

[0007] Furthermore, for the ground area, the dangerous area division markers can be directly placed at designated locations by manpower or machinery, or can be dropped to target locations using drones.

[0008] Furthermore, the target positioning algorithm integrates surf features and color features. The color features are based on the video captured by the drone. The input video series M1,...,M n , and the light-emitting position M1 (pos1, pos2, .., posn) in the tracking target position of the 1st frame; the tracking target position pos1, ..., posn of the output video series.

[0009] Furthermore, the specific steps of the target positioning algorithm are:

[0010] 1) Extract the tracking target position pos1 in the first frame;

[0011] 2) Initialize the target tracker;

[0012] 3) Calculate the surf features of the tth frame, and segment surf1 and surf2, and perform correlation filtering on each;

[0013] 4) Perform Fourier transform using circulant matrices and select the best result of filtering;

[0014] 5) Extract the color attribute features of the t-th frame;

[0017] Furthermore, the specific steps of performing Fourier transform using circulant matrices and selecting the best result of filtering processing are:

[0018] A. Feature extraction: Grayscale, compress, and normalize the video frame. Then, divide the image into cells of equal size and calculate the corresponding gradient histogram information. Then, concatenate all the cell features to form a large overlapping block, and calculate the histogram characteristics of the entire block. Then, normalize the gradient histogram within each block, and finally concatenate the feature vectors of the entire block to form the feature vector x.

[0019] The regression solution is obtained by Fourier transforming the eigenvector using the circulant matrix;

[0020] C. Search for the maximum value R of the surf feature max: Calculate the maximum value R of the response value R of the rectangular area p of the feature map with the same size as the feature vector x max .

[0022] A.X'=X·C, where X is the color data matrix, C is the target area color mask, and C=X'×w;

[0023] B. Set the surf feature maximum value R max Combined with the color information X', different colors of the logo are identified.

[0024] Furthermore, the wireless communication module can receive command information from the emergency command center and dynamically adjust the reported danger level information and light color according to the command content.

[0025] Furthermore, the information sharing software also has a rights management function, which can provide corresponding levels of information access and operation permissions according to the responsibilities and permissions of different departments.

[0026] A method for managing a dangerous area identification system based on nuclear emergency events includes the following steps:

[0027] (1) Dangerous area demarcation and sign placement: Place the sign at the target location by manpower, machinery or drone;

[0028] (2) Positioning and information reporting: Through the built-in target positioning algorithm of the target tracker, once it is turned on, it automatically reports its precise location, determines the danger zone and the current danger level information to the information sharing software;

[0029] (3) Rapid response and dynamic adjustment: The information sharing software is responsible for receiving and integrating the data from the hazardous area division identification to form a unified hazardous area map for rapid response and processing. At the same time, the wireless communication module can receive command information from the emergency command center and dynamically adjust the reported hazard level information and light color according to the command content.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] (1) The explosion-proof and chemical-proof design and tumbler structure of the hazardous area demarcation sign of the present invention are waterproof and float on water, ensuring its stability and durability in various extreme environments. At the same time, it integrates a target tracker and target positioning algorithm, as well as an intelligent sign with information reporting function, to achieve real-time collection and uploading of hazardous area information.

[0032] (2) The present invention adopts information sharing software, which realizes the real-time updating and sharing of dangerous area information through an automated information reporting and receiving mechanism, significantly improves the emergency response speed, and realizes cross-departmental information integration and real-time sharing. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Figure 1 This is a structural diagram of the nuclear emergency hazard zone identification management system of the present invention. DETAILED DESCRIPTION

[0034] The present invention will be described in detail below with reference to specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those skilled in the art, several changes and improvements can be made without departing from the scope of the present invention. These all fall within the scope of protection of the present invention.

[0035] like Figure 1 As shown, a dangerous area identification management system based on nuclear emergency events includes a dangerous area division mark, a target tracker, a wireless communication module and information sharing software. The dangerous area division mark is provided with a target tracker, a wireless communication module and a light-emitting device. The dangerous area division mark adopts a tumbler shape and an integrated light-emitting device, which can facilitate on-site personnel to quickly identify the danger level. The target tracker has a built-in target positioning algorithm. Once turned on, it automatically reports its precise location, determines the dangerous area and the current danger level information to the information sharing software. The information sharing software is responsible for receiving and integrating data from the dangerous area division mark to form a unified dangerous area map. The map can display the location, size and danger level of each dangerous area in real time, so that the emergency command center can grasp the location information of each dangerous area in real time, providing strong support for subsequent emergency response.

[0036] Traditional signage is often made of ordinary plastic or metal, which are easily damaged in nuclear emergencies, making it difficult to maintain the integrity and readability of the sign. This invention utilizes explosion-proof and chemical-resistant materials, which are not only high-strength and high-toughness, but also effectively resist corrosion from extreme environments like radiation and chemical corrosion. Through a special treatment process, the sign's surface also has a self-cleaning function, preventing the adhesion of dust and oil, further extending the sign's service life.

[0037] Traditional signage often tilts or collapses due to factors like wind and terrain, making it difficult to accurately convey information. This new design utilizes a tumbler-shaped sign. This shape provides inherent stability, allowing the sign to remain upright even in uneven terrain or strong winds. Furthermore, the tumbler-shaped sign is easy to carry and place, reducing operational complexity and improving the efficiency of emergency response.

[0038] To visually display the hazard level, the present invention incorporates an integrated lighting device within the sign. This device utilizes an energy-efficient LED light source, emitting red, yellow, and green lights to differentiate between hazard levels. Red represents high hazard, yellow represents moderate hazard, and green represents safe or low-risk areas. This intuitive color display not only facilitates quick identification of hazard levels by on-site personnel, but also provides clear visual guidance at night or in low-light conditions.

[0039] Multiple placement methods are available to meet the needs of different emergency scenarios. For ground-level areas, signs can be placed directly at designated locations using manual or mechanical methods. For high-altitude or hard-to-reach locations, signs can be placed using aircraft such as drones. This flexible placement method significantly improves sign coverage and speeds emergency response.

[0040] The present invention uses a built-in target positioning algorithm within the target tracker. Once activated (e.g., by a reconnaissance officer or drone), it automatically reports its precise location, identifying the danger zone and its current danger level to information sharing software. This allows the emergency command center to obtain real-time location information for each danger zone, providing strong support for subsequent emergency response.

[0041] The target localization algorithm integrates surf features and color features. The color features are based on the video captured by the drone. The input video series M1,...,M n , and the light-emitting position M1 (pos1, pos2, .., posn) in the tracking target position of the 1st frame; the tracking target position pos1, ..., posn of the output video series.

[0042] The specific steps are:

[0043] 1) Extract the tracking target position pos1 in the first frame;

[0044] 2) Initialize the target tracker;

[0045] 3) Calculate the surf features of the tth frame, and segment surf1 and surf2, and perform correlation filtering on each. The correlation filter model is as follows: Where F and G are input image and response output;

[0046] 4) Perform Fourier transform using circulant matrices and select the best result of filtering;

[0047] 5) Extract the color attribute features of the t-th frame;

[0048] 6) Fusing the best surf features and color attribute features to obtain a feature response map;

[0049] 7) Find the target position pos1,...,posn according to the response graph until the end of the video.

[0050] In step 4), the specific steps of performing Fourier transform using circulant matrices and selecting the best result of filtering are as follows:

[0051] A. Feature extraction: Grayscale, compress, and normalize the video frame. Then, divide the image into cells of equal size and calculate the corresponding gradient histogram information. Then, concatenate all the cell features to form a large overlapping block, and calculate the histogram characteristics of the entire block. Then, normalize the gradient histogram within each block, and finally concatenate the feature vectors of the entire block to form the feature vector x.

[0052] B. Using the circulant matrix to perform Fourier transform on the eigenvector, the regression solution is: in is the vector after Fourier transformation, * represents the complex conjugate;

[0053] C. Search for the maximum value R of the surf feature max : Calculate the maximum value R of the response value R of the rectangular area p of the feature map with the same size as the feature vector x max :

[0054] In the formula, d is the characteristic dimension, which ranges from 1 to D.

[0055] In step 6), the specific steps of fusing the best surf features and color attribute features to obtain the feature response map are as follows:

[0056] A.X'=X·C, where X is the color data matrix and C is the target area color mask.

[0057] C = X' × w;

[0058] B. Set the surf feature maximum value R max Combined with the color information X', different colors of the logo are identified.

[0059] The information sharing software receives and integrates data from various markers to create a unified danger zone map. This map displays real-time information such as the location, size, and hazard level of each danger zone, supporting multiple query and display methods. Furthermore, the information sharing software includes permission management, providing appropriate levels of information access and operational permissions based on the responsibilities and authority of different departments. This allows each department to quickly obtain the information they need based on their actual needs, enabling coordinated operations and efficient emergency response.

[0060] The present invention also integrates a wireless communication module within the sign, which is capable of receiving command information from the emergency command center and dynamically adjusting the reported danger level information and lighting color based on the command content. This allows the system to quickly respond and update relevant information as the danger zone level changes as the accident progresses, ensuring the accuracy and timeliness of the information. When the sign receives new danger level information, the built-in lighting device automatically adjusts the lighting color based on the command content. This intuitive visual feedback method not only allows on-site personnel to quickly identify changes in danger levels, but also enhances the sense of urgency and effectiveness of emergency response.

[0061] A method for managing a dangerous area identification system based on nuclear emergency events includes the following steps:

[0062] (1) Dangerous area demarcation and sign placement: Place the sign at the target location by manpower, machinery or drone;

[0063] (2) Positioning and information reporting: Through the built-in target positioning algorithm of the target tracker, once it is turned on, it automatically reports its precise location, determines the danger zone and the current danger level information to the information sharing software;

[0064] (3) Rapid response and dynamic adjustment: The information sharing software is responsible for receiving and integrating the data from the hazardous area division identification to form a unified hazardous area map for rapid response and processing. At the same time, the wireless communication module can receive command information from the emergency command center and dynamically adjust the reported hazard level information and light color according to the command content.

[0065] This invention uses intelligent and automated means to achieve real-time information collection, reporting, and updating, greatly improving the speed and accuracy of emergency response. At the same time, through the support of information sharing software, various departments can grasp the situation in dangerous areas in real time and work together to form a powerful emergency response force.
