[0034] With the development of nuclear energy technology and the increase of nuclear facilities, emergency response to nuclear accidents has become a critical issue. When a nuclear accident occurs, a quick and accurate inventory of nuclear emergency personnel is the key to ensuring personnel safety and effectively responding to the accident. However, there are some technical and operational limitations in the existing nuclear emergency personnel management system.

[0035] Traditional nuclear emergency personnel inventory systems usually rely on manual records or basic electronic tag systems, which have deficiencies in accuracy, efficiency and security. For example, manual records are prone to errors and are not suitable for rapid large-scale personnel inventory; although the electronic tag system increases the inventory speed, it does not work properly when the tag is damaged or lost, and cannot provide biometric verification of personnel.

[0036] In addition, existing recognition technologies are often limited to a single recognition method, which may fail due to environmental factors, occlusion, or non-cooperative behavior. Especially in high-risk environments such as nuclear emergencies, these limitations may have a significant impact on personnel safety.

[0037] In view of the above problems, the present invention provides an emergency response method based on nuclear emergency personnel inventory and evacuation, which aims to achieve efficient and accurate inventory of personnel in a nuclear emergency environment by integrating and innovating multiple recognition technologies (including but not limited to image recognition and biometrics), thereby improving the overall capability of nuclear accident emergency response.

[0038] This application example provides an example of a nuclear power plant emergency response method. Please refer to Figure 1 As shown, Figure 1 A schematic flow chart of a nuclear power plant emergency response method provided by the present application is shown. As an example but not a limitation, the method can be applied to a nuclear power plant emergency response system. The method includes:

[0039] S101, when a nuclear power plant is in an emergency response state, obtaining current position information and current state information of a first target object in an emergency location of the nuclear power plant, wherein the first target object is used to characterize a traceable object within a monitoring range.

[0040] S102, obtaining the last position information of a second target object in the emergency location, wherein the second target object is used to represent an untraceable object that is not within the monitoring range.

[0041] S103, determining target object inventory information corresponding to the emergency site based on the current location information and current state information of the first target object and the last location information of the second target object, wherein the target object inventory information is used to characterize the number and location information of the non-evacuated objects in the first target object and the second target object.

[0042] S104: Determine a corresponding evacuation strategy based on the target object inventory information, so as to assist the non-evacuated objects among the first target object and the second target object to evacuate from the emergency site based on the evacuation strategy.

[0043] Optionally, the current status information of the first target object includes at least one of the following: assembled, evacuated, decontaminated, and resettled. The above-mentioned first target object includes assembled personnel, evacuated personnel, decontaminated personnel, resettled personnel, etc., who can be clearly tracked and managed during the emergency response process, are in a known link of the emergency response, and have corresponding information records in the emergency management system, such as current location information, conversion time of different status information, etc.

[0044] Optionally, the above-mentioned second target object includes: a tracked person or a missing person. The current location information and current status information of the second target object are unknown during the emergency response process. Only the last location information of the second target object is known. However, the second target object is currently out of the monitoring scope of the normal emergency management process and is an object that requires special attention and search.

[0045] In the example of this application, at least one biometric device and at least one identification tag code can be set up in the nuclear power plant. The at least one biometric device and the mobile device used to scan the identification tag code are connected to the database of the nuclear power plant emergency response system and the emergency command server respectively. The at least one biometric device includes: a fixed face recognition device and a mobile face recognition device. For example, the fixed face recognition device can be pre-installed at the entrance, exit and important monitoring points of the emergency site. The fixed face recognition device is equipped with a high-resolution camera and advanced face recognition technology to identify the biometric information (such as facial feature information, pupil feature information, etc.) of at least one target object (including the first target object or the second target object).

[0046] When the target object (including the first target object or the second target object) stays at the installation location of the fixed face recognition device, or the target object passes through the installation location of the fixed face recognition device, the fixed face recognition device can quickly and accurately identify the biometric information of the target object, and can also verify the biometric information of the target object to obtain the identity information of the target object (for example, personnel ID, name, identity code, etc.), and upload the biometric information and / or identity information to the emergency command server of the nuclear power plant emergency response system to update the current location information of the target object in real time, so that the emergency command server can obtain the current location information of the first target object (such as assembled personnel, disinfected personnel, etc.) in the emergency site, and the last location information of the second target object (such as missing persons).

[0047] In the example of this application, in a nuclear power plant, mobile face recognition equipment is quickly deployed on-site by emergency response personnel and integrated into handheld devices or wearable devices, such as tablet computers or smart glasses. In a rapidly changing emergency response environment, the use of mobile face recognition equipment to perform facial biometrics or pupil feature recognition on the target object can achieve real-time acquisition of the target object's biometric information at a temporary gathering point or accident site in an emergency location. In addition, the mobile face recognition device transmits the recognized biometric information to the emergency command server in real time to assist the emergency command server in determining the current location information of the first target object and the last location information of the second target object in the emergency location.

[0048] In addition, the identification tag code (for example, a QR code) pre-set in the emergency site can be scanned by the target object using a smartphone or other mobile device with a QR code scanning function when the target object arrives at the emergency site, thereby recording the target object's own current location information and scanning time information in real time. When used in combination with at least one of the above-mentioned biometric devices, dual verification is provided, allowing the emergency command server to further clarify the current location information of the first target object and the last location information of the second target object.

[0049] According to the current position information and current state information of the first target object, and the last position information of the second target object, the target object inventory information corresponding to the emergency site is determined. For example, the emergency command server of the nuclear power plant emergency response can comprehensively analyze and process the current position information and current state information of the first target object, and the last position information of the second target object, to obtain the number and position information of the non-evacuated objects in the first target object and the second target object, that is, the target object inventory information. Specifically, the real-time personnel inventory reporting unit of the emergency command server can be used to automatically generate at least one of the following types of personnel during the emergency response period according to the current position information and current state information of the first target object, and the last position information of the second target object: the number and position information of the assembled personnel, the evacuated personnel, the left-behind personnel, the missing personnel, the resettled personnel, etc., and the number and position information of the non-evacuated personnel (if the position of the missing person is uncertain, the position information is the last known position information).

[0050] Finally, based on the target object inventory information determined in the above example, the emergency command server conducts statistical tracking of the personnel status and formulates a reasonable evacuation strategy to ensure the scientificity and effectiveness of personnel evacuation under emergency response conditions. For example, based on the number and location information of non-evacuated objects at each emergency assembly point, the evacuation strategy can be determined to determine how many evacuation vehicles, protective equipment, and medical resources are needed, so as to avoid over-allocation or under-allocation of resources and improve the accuracy of resource allocation. Furthermore, according to the evacuation strategy, evacuation vehicles can be uniformly dispatched to each emergency assembly point to carry non-evacuated objects, and the person in charge of each emergency assembly point can organize the non-evacuated objects to get on the nearest vehicle and evacuate from the emergency assembly point.

[0051] Through the nuclear power plant emergency response method provided by the example of this application, first, when the nuclear power plant is in an emergency response state, any one or more biometric identification methods and scanning identification methods are used to obtain the current position information and current state information of the first target object within the monitoring range in the emergency site of the nuclear power plant, as well as the last position information of the second target object that is not within the monitoring range in the emergency site; then, according to the current position information and current state information of the first target object, and the last position information of the second target object, the number and position information of the unevacuated objects in the first target object and the second target object in the emergency site are determined; further, the corresponding evacuation strategy is determined based on the target object inventory information, so as to assist the unevacuated objects in the first target object and the second target object to evacuate from the emergency site based on the evacuation strategy. The accuracy of emergency response operations in nuclear power plants can be improved, and corresponding evacuation strategies can be formulated based on accurate personnel inventory information, so that the emergency resources of nuclear power plants can be more reasonably deployed.

[0052] For a possible implementation, please refer to Figure 2 As shown, Figure 2 A schematic flow chart of an optional nuclear power plant emergency response method provided by the present application is shown, which obtains current location information and current status information of a first target object in an emergency site of a nuclear power plant, including:

[0053] S201, obtaining biometric information obtained by at least one biometric identification device identifying a biometric feature of a first target object;

[0054] S202, determining first associated information of the biometric information of the first target object, wherein the first associated information includes: collection time information, collection location information, and an associated relationship with a specific event, where the specific event includes at least one of the following: a gathering event, an evacuation event, a decontamination event, and a placement event;

[0055] S203, determining the current location information of the first target object based on the collection time information and the collection location information of the biometric information of the first target object;

[0056] S204, determining current status information of the first target object based on the association between the biometric information of the first target object and the specific event, wherein the current status information includes at least one of the following: assembled, evacuated, disinfected, and settled.

[0057] Optionally, the at least one biometric recognition device includes: a fixed face recognition device and a mobile face recognition device.

[0058] In the example of this application, in a nuclear power plant, a fixed face recognition device is installed at the entrance, exit and important monitoring points of the emergency site. The fixed face recognition device is equipped with a high-resolution camera and advanced face recognition technology to identify the biometric information of the target object (staff, etc.). When the first target object stays at the fixed face recognition device or passes through the installation location of the fixed face recognition device, the fixed face recognition device can quickly and accurately identify the biometric information of the first target object and determine the first associated information of the biometric information of the first target object.

[0059] In the example of this application, in a nuclear power plant, mobile facial recognition equipment is quickly deployed on-site by emergency response personnel and integrated into handheld devices or wearable devices, such as tablet computers or smart glasses. In a rapidly changing emergency response environment, facial biometrics or pupil features can be recognized at a temporary assembly point or accident site in an emergency location to obtain the biometric information of the first target object. In addition, the fixed biometric device and the mobile biometric device transmit the identified biometric information to the emergency command server, which can be transmitted by wire or wireless means to ensure the timeliness and accuracy of the transmission of biometric information.

[0060] After receiving the biometric information of the first target object, the emergency command server determines the first associated information of the biometric information of the first target object, wherein the first associated information includes: collection time information (or acquisition time), collection location information (such as the installation location of the fixed face recognition device, the use location of the mobile face recognition device, etc.), and an associated relationship with a specific event. As an example but not limitation, the specific event includes at least one of the following: a gathering event, an evacuation event, a decontamination event, and a placement event.

[0061] The current location information of the first target object can be determined based on the collection time information and collection location information of the biometric information of the first target object; for example, based on the latest collection time of each collection location, the current location information of the first target object identified at the emergency assembly point is the “emergency assembly point”; the current location information of the first target object identified on the evacuation vehicle is the “evacuation vehicle”; the current location information of the first target object identified at the decontamination and disinfection point is the “decontamination and disinfection point”, etc.

[0062] According to the association relationship between the biometric information of the first target object and the specific event, the current state information of the first target object can be determined. For example, if the biometric information of the first target object is associated with the gathering event, the current state information of the first target object is "gathered"; if the biometric information of the first target object is associated with the evacuation event, the current state information of the first target object is "evacuated"; if the biometric information of the first target object is associated with the decontamination event, the current state information of the first target object is "decontaminated", etc.

[0063] For a possible implementation, please refer to Figure 3 As shown, Figure 3 A schematic flow chart of an optional nuclear power plant emergency response method provided by the present application is shown, and obtaining the last position information of the second target object in the emergency site includes:

[0064] S301, obtaining biometric information obtained by at least one biometric recognition device recognizing a biometric of a second target object;

[0065] S302, determining second associated information of the biometric information of the second target object, wherein the second associated information includes: collection time information and collection location information.

[0066] S303: Determine the last location information of the second target object based on the collection time information and the collection location information of the biometric information of the second target object.

[0067] In the example of this application, the fixed face recognition device continues to operate at various key locations in the emergency site, constantly scanning the surrounding environment and trying to identify the possible second target object. Even when the nuclear power plant is in an emergency state, the fixed face recognition device can still capture any biometric information related to the second target object with its high-resolution camera and advanced face recognition technology. In addition, the mobile face recognition device is carried by emergency responders (not the first or second target object) to conduct a focused search in areas where the second target object may exist. Due to the portability of the mobile face recognition device, it can be flexibly deployed to various complex terrains or areas where fixed face recognition devices are not deployed, thereby increasing the probability of discovering the biometric information of the second target object.

[0068] As an optional implementation, once any biometric identification device identifies the biometric information of the second target object, it immediately transmits the biometric information of the second target object to the emergency command server. It should be understood that whether through a wired connection or a wireless transmission method, it can ensure that the biometric information is quickly and accurately transmitted to the emergency command server for timely subsequent processing.

[0069] Afterwards, after receiving the biometric information, the emergency command server determines the second associated information of the biometric information of the second target object, wherein the second associated information includes: collection time information and collection location information; and then the emergency command server can determine the last location information of the second target object based on the collection time information and collection location information of the biometric information of the second target object.

[0070] In addition, after receiving the biometric information, the emergency command server can also compare the biometric information with the basic information stored in the local database of the nuclear power plant emergency response system, which stores the basic information of all target objects, including but not limited to name, identity code, contact information, etc. By comparing or matching the biometric information with the basic information, the specific identity information of the second target object can be determined, so as to enhance the possibility of tracking and rescuing the second target object.

[0071] In a possible implementation, when the biometric identification device is a fixed biometric identification device, the biometric identification device is fixedly installed at at least one of the following locations in the emergency location: an entrance, an exit, and a monitoring point.

[0072] In another possible implementation, when the biometric device is a mobile device, the biometric device is integrated into a handheld device or a wearable device, so as to be movably set at a temporary assembly point or accident site in an emergency location.

[0073] By setting up fixed biometric devices at the entrance of the emergency site in advance, when any target object enters the emergency site, the fixed biometric device can quickly identify its biometric information, record the collection time information, collection location information, and association with specific events corresponding to the identification of the biometric information, so as to accurately grasp the situation of personnel entering the emergency site, effectively manage the inflow of personnel in an emergency, and provide initial data for subsequent personnel inventory and tracking.

[0074] By setting up fixed biometric equipment at the exit of the emergency site in advance, the departure of any target object (any person in the emergency site) can be monitored. If people evacuate during the emergency response process, the fixed biometric equipment can promptly identify and record the biometric information of the evacuated people, and record the corresponding collection time information, collection location information, and association with specific events when the biometric information is identified, providing real-time data for determining the existing people in the emergency site.

[0075] By installing fixed biometric devices at important monitoring points in emergency sites, specific areas can be monitored. For example, by installing monitoring points in areas where key equipment or materials are stored, the safety of these important resources can be ensured, and any unauthorized personnel approaching can be detected in a timely manner. For example, for areas that may be dangerous or require special attention, such as areas with high radiation, fixed biometric devices can monitor the entry and exit of personnel in real time, so as to track the personnel in these areas and take appropriate protective measures or conduct emergency rescue when necessary.

[0076] Integrating biometric devices into handheld devices (such as tablets) or wearable devices (such as smart glasses) allows emergency responders (non-first or second target objects) to have high flexibility and mobility on site. At temporary assembly points, due to the high mobility of personnel, traditional fixed biometric devices may not be able to fully cover all areas, while mobile devices can be carried by emergency responders to identify and verify the first target object and / or the second target object at any time.

[0077] In addition, in areas such as temporary assembly points or accident sites, the situation is often complex and changeable, and there may be obstacles, narrow passages or dangerous areas. Mobile biometric devices can be flexibly deployed according to actual conditions, are not restricted by fixed locations, and can quickly and accurately identify the biometric information of the target object, improving the efficiency and accuracy of emergency response inventory.

[0078] For example, at a temporary assembly point, people may constantly join or leave, and mobile devices can identify and register new arrivals at any time, and can also reconfirm registered personnel to ensure the accuracy and completeness of personnel information. For another example, at an accident site, emergency situations may change at any time, such as fire spread, building collapse, etc. Mobile biometric devices can adjust their positions as emergency responders move, continuously monitor and identify target objects, and provide timely information support for rescue and evacuation decisions.

[0079] In a possible implementation, obtaining current location information of a first target object in an emergency location of a nuclear power plant includes:

[0080] Based on at least one identification tag code set in the emergency place, the current location information of the first target object in the emergency place is determined, wherein when the first target object uses a mobile device to scan the identification tag code set in the emergency place, the basic information, current location information and scanning time information of the first target object reported by the mobile device are obtained, and the basic information includes: name, identity code, and contact information.

[0081] In the example of this application, by setting up at least one identification label code, such as an emergency site QR code, in the emergency site of the nuclear power plant, an important positioning basis is provided for determining the current location information of the first target object. These label codes can be affixed to any location in the emergency site to facilitate the first target object to scan using a mobile device.

[0082] When the first target object uses a mobile device to scan the identification tag code, the mobile device will report the first target object's basic information (such as personal ID, name, etc.), current location information (obtained through the positioning function of the mobile device, such as GPS positioning or manually entered location information) and scanning time information.

[0083] The emergency command server receives the basic information, current location information and scanning time information of the target object reported by the mobile device. Using data analysis technology, the current location information and scanning time information of each first target object are processed and analyzed, and the target object can be located in the emergency site according to the current location information, and the current location information of the first target object can be determined by combining factors such as scanning time information. In addition, the current location information and movement trajectory of the first target object can be displayed on a map or in a chart through visualization means, so that the current location information of the first target object in the emergency site can be tracked and understood more intuitively.

[0084] In a possible implementation, obtaining the last location information of the second target object in the emergency location includes:

[0085] Based on at least one identification tag code set in the emergency place, the last location information of the second target object in the emergency place is determined, wherein when the second target object uses a mobile device to scan the identification tag code set in the emergency place, the basic information, current location information and scanning time information of the second target object reported by the mobile device are obtained, and the last location information is determined based on the current location information of the second target object last reported by the mobile device, and the basic information includes: name, identity code, and contact information.

[0086] In the present application example, identification tag codes set in the nuclear power plant, such as the emergency site QR code, are distributed in various key locations of the emergency site, providing a way for the target object to actively report its own information, which can serve as an important source of clues for determining the last location information of the second target object.

[0087] When the second target object uses a mobile device to scan the identification tag code under normal circumstances, the mobile device will report the basic information, current location information and scanning time information of the second target object. It should be understood that even if the target object is not considered missing under normal circumstances, these scanning records may play an important role when the second target object is missing in the future. For example, the current location information of the second target object last reported by the mobile device can be used as the last location information of the second target object, which improves the accuracy and reliability of determining the last location information of the second target object. Furthermore, the specific search range in the evacuation strategy can be determined based on the last location information, guiding emergency rescue personnel to conduct focused searches in possible areas, thereby increasing the probability of finding the second target object.

[0088] In addition, as an example but not limitation, the basic information of the second target object reported by the mobile device, such as personnel ID, name, etc., can be associated and matched with the basic information of the target object recorded in the personnel database of the nuclear power plant. If a target object is found missing during the emergency response process, the emergency command server can quickly determine the identity information of the target object based on the basic information of the target object, providing a basis for subsequent tracking, search and rescue work.

[0089] In this application example, in addition to the last location information reported in real time by the target object's mobile device, the emergency command server can also query the historical scanning records in the identification tag code system. If the second target object has scanned a tag code at a certain location at a certain point in the past, tracking clues about the activity trajectory of the second target object can be determined based on the historical records. By analyzing the scanning time sequence and position changes of the historical records, the movement direction and possible destination of the second target object can be inferred.

[0090] In a possible implementation, the identification tag code is also set on the evacuation vehicle, and the decontamination and disinfection point and emergency placement point in the nuclear power plant. The method also includes:

[0091] When it is detected that the first target object and / or the second target object uses a mobile device to scan an identification tag code set on an evacuation vehicle, basic information and evacuation time of the first target object or the second target object reported by the mobile device are obtained;

[0092] When the first target object or the second target object is monitored and the mobile device is used to scan the identification tag code set in the decontamination and disinfection point, the basic information and disinfection information of the first target object or the second target object reported by the mobile device are obtained;

[0093] When the first target object or the second target object is monitored and the mobile device is used to scan the identification tag code set in the emergency placement point, the basic information and placement information of the first target object or the second target object reported by the mobile device are obtained.

[0094] In this application example, an identification tag code (such as a QR code) is set in an evacuation vehicle (such as a vehicle, helicopter, etc.). When the target object (the first target object or the second target object) scans the tag code using a mobile device (such as a smart phone), the mobile device reports the basic information and evacuation time of the target object to the emergency command server.

[0095] It should be understood that the basic information of the target object reported by the mobile device (such as personnel ID, name, etc.) is helpful for accurately identifying the identity information of the target object in the entire emergency response state; the evacuation time is a time node information that can clearly identify the target object to evacuate by evacuation transportation, which is helpful for subsequent personnel inventory, evacuation progress monitoring and traceability analysis. For example, by comparing the evacuation time of different target objects, the order of evacuation can be understood and whether there is a delay.

[0096] In addition, since nuclear power plant accidents may lead to radioactive contamination, decontamination is an important part of ensuring the health and safety of personnel. By setting identification tag codes at the decontamination points of nuclear power plants in advance, the basic information and decontamination information of the target object (such as the start time of decontamination, whether the decontamination is completed, whether it meets the safety standards, etc.) can be obtained when the target object is scanned, and the emergency command server can grasp the decontamination status of each target object in real time.

[0097] As an example but not a limitation, the basic information of the target object is used to accurately identify the identity information of the target object, and the decontamination information can be used to arrange the subsequent command process. For example, if the decontamination is not completed or does not meet the standards, the target object can be further processed or re-arranged for decontamination. At the same time, the basic information and decontamination information of the target object can be summarized to the emergency command server to provide data support for determining emergency decisions and evacuation strategies, such as judging the work efficiency of the decontamination point and whether more resources need to be deployed.

[0098] Afterwards, by setting up an identification tag code at the emergency resettlement site in advance, after the target object uses a mobile device to scan the identification tag code, the basic information and resettlement information of the target object are reported through the mobile device. The basic information of the target object is used again for identity confirmation to avoid confusion during the resettlement process. The resettlement information may include the resettlement location, resettlement start time, whether special care is needed, etc., which can help the emergency management department to reasonably arrange resettlement resources. For example, according to whether the target object needs special care, the corresponding medical resources or daily necessities are allocated, which helps to ensure that the target object is properly managed at the resettlement site. At the same time, through the analysis of a large number of target object resettlement information, the accommodation capacity of the resettlement site and the rationality of resource allocation can be evaluated.

[0099] An optional nuclear accident emergency personnel collection and management architecture is provided for the above application scenarios. Figure 4 As shown, Figure 4 A schematic diagram of an optional nuclear accident emergency personnel collection inventory and management architecture provided by the present application is shown, in which:

[0100] In addition to the traditional clock-in devices, fixed face recognition devices, mobile face recognition devices and the place codes corresponding to the emergency assembly points are set up at the emergency assembly points in the nuclear power plant (such as emergency assembly point 1..., emergency assembly point N). After arriving at the emergency assembly point, personnel can choose to sign in in one of several ways. Selecting the face recognition device requires biometric recognition, and selecting the QR code method requires using the built-in intelligent communication collection and using an adapted dedicated application to scan the code. Mobile face recognition devices are used as auxiliary tools for emergency management personnel, as a supplement to other methods when resources are tight, or there is no smartphone or the device is unavailable. In this scenario, the information of the assembled personnel (including personnel ID, personnel name, personnel status-assembled, assembly time) is transmitted to the emergency command server by wired or wireless means (such as emergency dedicated network).

[0101] It should be noted that the emergency command server can also share all emergency response information or emergency command information received or obtained with the government server through the information sharing network.

[0102] In emergency evacuation vehicles and other means of transportation, set vehicle codes and mobile face recognition devices. After the evacuees get on the vehicle, they can choose to sign in in one of several ways. Selecting a face recognition device requires biometric recognition, and selecting a QR code requires using built-in intelligent communication collection and scanning with an adapted dedicated application. Mobile face recognition devices are used as an auxiliary tool for vehicle codes to supplement when personnel do not have smartphones or they are unavailable. The data in this scenario transmits the collected personnel information (including personnel ID, personnel name, personnel status-evacuated, evacuation time) to the emergency command server wirelessly.

[0103] At the decontamination and disinfection point, in addition to the traditional clock-in device, fixed facial recognition devices, mobile facial recognition devices and the place code corresponding to the emergency assembly point are set up. After arriving at the emergency assembly point, personnel can choose to sign in in one of several ways. Selecting a facial recognition device requires biometric recognition, and selecting a QR code requires using built-in intelligent communication collection and using an adapted dedicated application to scan the code. Mobile facial recognition devices are used as auxiliary tools for emergency management personnel, as a supplement to other methods when resources are tight, or when there is no smartphone or the device is unavailable. The data in this scenario transmits the information of the assembled personnel (including personnel ID, personnel name, personnel status-decontaminated, decontamination time) to the emergency command server wirelessly.

[0104] At the resettlement point, in addition to the traditional punch-in device, fixed face recognition devices, mobile face recognition devices and the location code corresponding to the emergency assembly point are set up. After arriving at the emergency assembly point, personnel can choose to sign in in one of several ways. Choosing a face recognition device requires biometric recognition, and choosing a QR code requires using the built-in intelligent communication collection and scanning the code using an adapted dedicated application. Mobile face recognition devices are used as auxiliary tools for emergency management personnel, as a supplement to other methods when resources are tight, or there is no smartphone or the device is unavailable. The data in this scenario transmits the basic information of the assembled personnel (including personnel ID, personnel name, personnel status-already settled, settlement time) to the emergency command server by wireless means. The above information is transmitted to the power plant emergency command server through network security protection equipment. The emergency command server conducts statistical tracking of the personnel status in the nuclear power plant to form real-time personnel status information required for command, including the number of personnel currently in each location, the number of personnel who have not arrived, and the list, etc.

[0105] The nuclear power plant emergency response system, also known as the nuclear emergency personnel inventory and evacuation dynamic management system, integrates multiple management modules to achieve real-time monitoring and management of personnel information in nuclear emergency situations. The system includes personnel management module, facility site management module, emergency personnel information module and QR code generation module, aiming to improve the efficiency and accuracy of nuclear emergency response.
