Description

Technical Field

[0001] The present application belongs to the technical field of nuclear emergency reconnaissance training, and in particular relates to a portable nuclear radiation reconnaissance simulation training system and a nuclear radiation reconnaissance training method. Background Art

[0003] Existing portable simulation training equipment is mainly concentrated in single-installation simulation training equipment, such as simulation radiation meters, which can be used in two ways. One is to use small magnets or NFC to simulate induction signals for fixed-point measurement, and the other is to use GPS / Beidou to calibrate the points. Both methods directly input empirical hazard field data, and do not perform simulated hazard field solutions based on the actual pollution environment. They only meet the needs of single-installation operation training and cannot be used for team / squad training based on large-scale accident diffusion scenarios.

[0004] At present, there are two main methods for nuclear radiation reconnaissance training in China. One is to conduct actual training in a weak source environment, and the other is to conduct radioactive source search training or fixed value boundaries in a simple scenario with single-point source or multiple-point source configuration. The first is a natural environment with relatively weak radiation dose. Considering the safety of training and the pollution of the environment, it is urgent to build a training method that can meet the requirements of actual training and ensure safety. The second is to construct a nuclear accident environment mainly in the form of a single-point source or a single leakage source. The specific disposal is relatively simple, and it is impossible to fully construct a scenario that meets the law of accident evolution. The military and local emergency support forces urgently need a system that can meet the needs of outdoor large-scale nuclear radiation reconnaissance training. The other is a system that can support team exercises. Since it must install fixed communication base stations and positioning base stations, it can only be trained in fixed rooms or outdoor positioning coverage areas, and it does not have the ability to be flexibly deployed.

[0005] At present, there are mainly two types of radiation reconnaissance / monitoring semi-physical simulation training systems at home and abroad. The first is a simple training mode that combines simulated radiation sources and detection simulators. This training method mainly uses the simulation principle of radio frequency signals, and constructs a simple hazard field environment based on the distance information between the simulator and the simulated radiation source. It is mainly used for radiation source search training. This mode is not restricted by the environment and can be carried out indoors and outdoors. The disadvantage is that it cannot construct a complex training environment according to user needs; the second is an indoor radiation reconnaissance simulation training system, which can construct a small real-life environment indoors, and combine indoor positioning technology and numerical simulation technology to construct a realistic small space high-intensity radiation hazard field simulation environment, which can meet the emergency reconnaissance training of professional emergency reconnaissance groups. The disadvantage is that it cannot construct an accident scene with a large accident boundary. Summary of the invention

It is explicitly and implicitly understood by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0058] The portable nuclear radiation reconnaissance simulation training system provided in the embodiment of the present application is intended to provide users with a highly integrated, portable and comprehensive simulation training tool. The system helps users train their reconnaissance skills by simulating a realistic nuclear radiation environment, thereby improving their ability to respond to nuclear radiation events.

[0059] like Figure 1As shown, an embodiment of the present application provides a portable nuclear radiation reconnaissance simulation training system, including an integrated portable control box, the integrated portable control box including a control terminal, a communication base station and a power module for supplying power to the control terminal and the communication base station; a virtual hazard environment construction unit deployed in the control terminal; and a portable communication terminal and an intelligent simulation perception terminal respectively placed in the integrated portable control box.

[0060] Specifically, in the integrated portable control box, the control terminal, as the core control part of the system, is responsible for receiving, processing and sending various instructions and data; the communication base station is responsible for the communication between the modules within the system, ensuring the real-time transmission of data and the accurate execution of instructions; the power module provides a stable power supply for the control terminal and the communication base station to ensure the continuous operation of the system.

[0061] The virtual hazard environment construction unit is deployed in the control terminal and is responsible for simulating and constructing the nuclear radiation hazard environment. Figure 2 As shown, the virtual environment construction unit includes a hazard scenario editing module, a radiation damage estimation module, a hazard situation display module, an equipment terminal management module, a basic data management module and an interactive data distribution module. The modules are interconnected to jointly realize the construction of the virtual environment and the processing of data.

[0062] Specifically, the virtual environment construction unit is the core part of the portable nuclear radiation reconnaissance simulation training system, which is responsible for constructing and simulating the virtual environment of nuclear radiation reconnaissance. The unit includes multiple interconnected modules, each of which has a specific function, including:

[0063] The hazard scene editing module is configured to set hazard field parameters. This module allows users to set and edit hazard field parameters in simulation training according to actual needs. These parameters may include the intensity, location, type, etc. of the radiation source, as well as environmental conditions such as wind direction and wind speed. By accurately setting these parameters, different nuclear radiation reconnaissance scenarios can be simulated to meet different training needs.

[0064] Specifically, when the hazard field parameters are set through the hazard scene editing module in the embodiment of the present application, the hazard field parameters include explosion latitude and longitude coordinates, explosion type, wind speed, wind shear angle, time discrete step length, explosion equivalent, attenuation index and spatial discrete length.

[0065] The Radiation Damage Estimation module is configured to perform hazard field distribution solutions and generate solution data. This module uses mathematical models and algorithms to calculate the distribution of hazard fields in space according to the parameters set by the Hazard Scenario Editing module. It generates solution data that describes the intensity of the hazard field at different locations and times. This data is essential for assessing radiation hazards, developing reconnaissance strategies, etc.

[0066] Specifically, in the radiation damage estimation module, the embodiment of the present application adopts a Gaussian plume model to solve the hazard field distribution and generate solution data. The formula is as follows:

[0067]

[0068] Where C(x, y, z) represents the concentration of the pollutant at the position (x, y, z), in Bq / m 3 ;

[0069] Q represents the amount of pollutant leakage per unit time, in Bq / s;

[0070] H represents the release height of the source, in meters;

[0071] σ y represents the lateral diffusion coefficient, which is the standard deviation of the pollutant distribution in the y direction;

[0072] σ z represents the vertical diffusion coefficient, which is the standard deviation of the pollutant distribution in the z direction;

[0073] Indicates the average wind speed in m / s;

[0074] K u Indicates the vaporization rate of the leaked material.

[0075] The calculation method of the diffusion coefficient is shown in the following table:

[0076] Table 1

[0077] Atmospheric stability <![CDATA[σ y ]]> <![CDATA[σ z ]]> A <![CDATA[0.22x / (1+0.0001x) 0.5 ]]> 0.2x B <![CDATA[0.16x / (1+0.0001x) 0.5 ]]> 0.12x C <![CDATA[0.11x / (1+0.0001x) 0.5 ]]> <![CDATA[0.08x / (1+0.0002x) 0.5 ]]> D <![CDATA[0.08x / (1+0.0001x) 0.5 ]]> <![CDATA[0.06x / (1+0.0015x) 0.5 ]]> E <![CDATA[0.06x / (1+0.0001x) 0.5 ]]> 0.03x / (1+0.0003x) F <![CDATA[0.04x / (1+0.0001x) 0.5 ]]> 0.016x / (1+0.0003x)

[0078] In the Gaussian plume model, when the leaking substance is gas, K u The value is 1; when the leaked substance is a hot liquid compound, K u The value formula is as follows:

[0079] K u =0.012(t c -t d )+0.2

[0080] Among them, t c and t d Respectively represent the temperature and boiling point of the liquid, in °C;

[0081] When t c ≤t d When K u The value is 0.2.

[0082] Furthermore, when the radiation damage estimation module calculates the location on the ground, z=0, and the formula is as follows:

[0083]

[0084] In another embodiment of the present application, the radiation level distribution of the explosion can also be described by a circular model, and the dose rate of the part overlapping with the cloud track area is taken as the sum of the two. After obtaining the nuclear explosion equivalent and specific height data, combined with the current environment of the explosion point, as long as the coordinates of the explosion center and the measuring point are known and the distance between the two points is calculated, the radiation level at different locations can be estimated. This method belongs to the prior art and will not be repeated here.

[0085] In another embodiment of the present application, the radiation dose can characterize the degree of harm caused by radioactive nuclides to the human body through irradiation, and is an important indicator to measure the harm of nuclear accidents to the environment and human health. Radioactive nuclides mainly cause radiation damage to the human body in the following ways: direct air immersion external irradiation and skin external irradiation caused by plumes; ground deposition external irradiation caused by accumulation of dry and wet deposition on the soil surface; inhalation internal irradiation caused by inhalation of radioactive nuclides in plumes; ingestion internal irradiation caused by ingestion of irradiated plants, animal products or drinking water. Radiation dose diagnosis estimates the impact of corresponding radiation doses on nuclear accidents based on the concentration values ​​of each pathway output by the radiation damage estimation module. The dose estimation needs to take into account the different stages of the accident. In the early stages of the accident, the radiation dose is mainly caused by air immersion external irradiation, ground deposition external irradiation and inhalation internal irradiation. The formula is as follows:

[0086] E im =C A DF im ·O f

[0087] E gr =C gr DF gr ·O f

[0088] E inh =C A ·R inh DF inh

[0089] Among them, E im Indicates air immersion external exposure; C A Indicates the concentration of radionuclides in the air, in units of (Bq·m -3 );DF im The effective dose conversion factor for air immersion external radiation is expressed in (Sv·a -1 ·Bq -1 ·m 3 );O fIt represents the dose reduction factor taking into account the time share of the public exposed to air containing radioactive materials and the shielding effect of buildings; E gr Represents ground deposition external irradiation; C gr Indicates the concentration of radionuclides deposited on the ground, in units of (Bq·m -2 );DF gr It represents the conversion factor of effective dose of external radiation deposited on the ground, in units of (Sv·a -1 ·Bq -1 ·m 2 );E inh Indicates internal radiation by inhalation; R inh Indicates the respiratory rate of a person, in units of (m 3 ·a -1 );DF inh Indicates the effective dose conversion factor of inhalation internal radiation, the unit is (Sv·Bq -1 ).

[0090] In the middle and late stages of the accident, the main concerns were external radiation from ground deposition, internal radiation from inhalation, and internal radiation from ingestion. The formula is as follows:

[0091] E ing，p =C p，i ·H p DF ing

[0092] Among them, E ing，p Indicates inhalation internal radiation; C p，i Indicates the concentration of radionuclides in food (Bq kg -1 );H p Indicates the consumption rate of food, in units of (kg·a -1 );DF ing Indicates the conversion factor of effective dose of internal radiation by ingestion, in units of (Sv·Bq -1 ).

[0093] The total effective dose is the sum of the effective doses of all radionuclides in all irradiation pathways, and the formula is as follows:

[0094]

[0095] Where m represents the number of nuclides and n represents the total number of irradiation pathways.

[0096] The hazard situation display module is configured to visualize the hazard field. This module converts the solution data generated by the radiation damage estimation module into intuitive graphics and images to display the distribution and changes of the hazard field. This helps users understand the characteristics of the hazard field more intuitively, so as to make more accurate judgments and decisions.

[0097] The device terminal management module is configured to set and collect basic data of the intelligent simulation perception terminal. This module is responsible for managing and configuring the intelligent simulation perception terminal, including setting its working parameters and collecting its basic data. Intelligent simulation perception terminals are important equipment in simulation training. They can simulate sensors and detectors in real environments and collect and transmit hazard field data.

[0098] The basic data management module is configured to modify user information and scene files. This module is responsible for managing user information and scene files in the system. User information may include the user's identity, permissions, etc., while the scene file contains the scene data required for simulation training. Through this module, users can easily modify and update this information to meet different training needs.

[0099] The interactive data distribution module is configured to send the solution data generated by the radiation damage estimation module to the intelligent simulation perception terminal for hazard field data collection. This module is a bridge connecting the radiation damage estimation module and the intelligent simulation perception terminal. It sends the solution data to the intelligent simulation perception terminal in real time, enabling them to simulate a realistic hazard field data collection process based on these data. This helps users experience the process of nuclear radiation reconnaissance more realistically in simulation training.

[0100] In summary, the modules of the virtual environment construction unit cooperate with each other to build a complete simulation training environment. By accurately setting hazard field parameters, calculating hazard field distribution, visualizing radiation situation, managing equipment terminals and basic data, and distributing interactive data, the system can provide users with an efficient and realistic nuclear radiation reconnaissance simulation training experience.

[0101] The portable communication terminal is placed in the integrated portable control box and has wireless communication function. It is responsible for transmitting the hazard field data in the hazard field and transmitting the data to the communication base station through the wireless module. At the same time, it can also receive instructions from the communication base station to adjust and control the intelligent simulation perception terminal.

[0102] Specifically, the portable communication terminal is a key component in the system, responsible for transmitting the hazard field data in the hazard field, and transmitting these data to the communication base station through the wireless module. At the same time, it can also receive instructions from the communication base station, and adjust and control the intelligent simulation perception terminal according to these instructions. The portable communication terminal is equipped with corresponding sensors or detection devices, which can transmit the hazard field data in the hazard field in real time, such as radiation intensity, radiation type, etc. The collected data is transmitted to the communication base station through the built-in wireless module. This wireless transmission method ensures the real-time and accuracy of the data, and also improves the flexibility and convenience of the system. The portable communication terminal can also receive instructions from the communication base station, which may include adjusting the working mode and parameter settings of the intelligent simulation perception terminal. The terminal performs corresponding operations according to the received instructions to ensure the normal operation of the system.

[0103] The communication base station is a bridge between the portable communication terminal and the virtual hazard environment construction unit, and it is responsible for realizing the communication between the two. At the same time, the communication base station is also responsible for receiving the hazard field data sent by the portable communication terminal, and forwarding these data to the virtual hazard environment construction unit for further processing. The communication base station communicates with the portable communication terminal wirelessly to ensure the real-time transmission of data and the accurate issuance of instructions. At the same time, it can also be connected to the virtual hazard environment construction unit by wire or wireless to realize data exchange and sharing. After the communication base station receives the hazard field data sent by the portable communication terminal, it will forward these data to the virtual hazard environment construction unit. The virtual hazard environment construction unit performs operations such as hazard field distribution solution and hazard situation display based on the received data to provide real-time hazard field information for trainees.

[0104] In the portable nuclear radiation reconnaissance simulation training system, the portable communication terminal and the communication base station work together to realize data collection, transmission and processing. Through this collaborative working mode, the system can obtain the hazard field data in the hazard field in real time and build a realistic virtual hazard environment based on this data. Trainees can conduct nuclear radiation reconnaissance simulation training in this virtual environment to improve their skills and response capabilities.

[0105] In summary, portable communication terminals and communication base stations are important components of portable nuclear radiation reconnaissance simulation training systems. Through collaborative work, real-time data collection, transmission and processing are realized, providing trainees with a realistic virtual hazard environment, thereby improving training effects and quality.

[0106] The intelligent simulation perception terminal is also placed in the integrated portable control box, which has the ability to perceive and simulate nuclear radiation environment. It simulates a realistic nuclear radiation environment based on the instructions and data received, providing users with a realistic training experience.

[0107] Specifically, in the intelligent analog sensing terminal, the system uses the LoRa wireless transmission channel to build a communication network. This network uses the communication base station as the central node and the portable communication terminal as the peripheral node. The LoRa wireless transmission channel is used as the link for data transmission, and finally forms a star topology network. Among them, the communication base station is the center of the entire network, responsible for receiving data from the portable communication terminal and forwarding it to the control terminal. It is also responsible for communicating between the portable communication terminal and the control terminal to ensure smooth data transmission. The portable communication terminal is a peripheral node of the network, responsible for transmitting the hazard field data in the hazard field. These data are transmitted to the communication base station through the wireless module. The portable communication terminal can also receive instructions from the communication base station for adjusting and controlling the intelligent analog sensing terminal.

[0108] LoRa (Long Range) is a low-power wide area network communication technology with the advantages of long transmission distance and low power consumption. In this system, the LoRa wireless transmission channel is used as a link for data transmission to ensure that data can be transmitted smoothly between the portable communication terminal and the communication base station. The star topology is a network topology in which all nodes are connected to the central node through separate links. In this system, the communication base station serves as the central node, and the portable communication terminal serves as the peripheral node, which is connected to the central node through the LoRa wireless transmission channel, forming a star topology network.

[0109] LoRa technology has the advantage of long transmission distance, enabling portable communication terminals to communicate with communication base stations at a longer distance. LoRa technology also has the advantage of low power consumption, which helps to extend the battery life of portable communication terminals. The star topology has the advantage of good network stability because all nodes are connected to the central node through separate links, reducing the possibility of network failure.

[0110] The star topology networking mode formed by using LoRa wireless transmission channel, communication base station as central node, portable communication terminal as peripheral node and LoRa wireless transmission channel as link has significant advantages in intelligent analog sensing terminal. This networking mode not only improves the stability and reliability of data transmission, but also reduces the power consumption and cost of the system.

[0111] In summary, the portable nuclear radiation reconnaissance simulation training system of the embodiment of the present application is highly integrated, and all modules and components are integrated in an integrated portable control box, which is easy to carry and transport. The system covers all the functions required for nuclear radiation reconnaissance training, including environmental simulation, data acquisition, command transmission, etc. Through wireless communication and real-time data processing technology, it is ensured that the system can reflect changes in the nuclear radiation environment in real time. The system adopts an intuitive operating interface and a simple operating process to facilitate users to quickly get started and train efficiently. The system is suitable for various training scenarios that require nuclear radiation reconnaissance skills, such as military training, emergency rescue, nuclear power plant operation and maintenance, etc. By simulating a realistic nuclear radiation environment, it helps users improve their ability and skill level to deal with nuclear radiation incidents.

[0112] like Figure 3 As shown, the embodiment of the present application also provides a nuclear radiation reconnaissance training method, comprising the following steps:

[0113] Step 301, training preparation stage.

[0114] In the embodiment of the present application, step 301, i.e., the training preparation stage, is the basis and premise of the entire training process. The main task of this stage is to build a virtual nuclear radiation hazard environment to provide necessary scenes and data support for subsequent training.

[0115] The embodiment of the present application first needs to start the control terminal, portable communication terminal and intelligent simulation perception terminal in the integrated portable control box, and establish a communication connection through the communication base station. The control terminal is the core of the entire training system, responsible for managing and coordinating the operation of each module. The virtual hazard environment construction unit is started and run by the control terminal to provide a basis for the subsequent virtual environment construction. In the control terminal, the virtual hazard environment construction unit is run. The virtual hazard environment construction unit is the key to constructing a virtual nuclear radiation hazard environment, including a hazard scenario editing module, a radiation damage estimation module, a hazard situation display module, an equipment terminal management module, a basic data management module and an interactive data distribution module. Each module is interconnected to realize the editing of hazard scenarios, the distribution solution of hazard fields, and the visualization display and other functions.

[0116] Next, the hazard scene editing module in the virtual hazard environment construction unit is used to determine whether there is pre-stored hazard field data in the local data. If so, these data are directly loaded, and the distribution of the hazard field is solved through the radiation damage estimation module. After the solution is completed, the hazard situation display module performs a visual display to construct a virtual hazard field. If there is no pre-stored hazard field data locally, it is necessary to perform simulation editing through the hazard scene editing module. This includes setting the parameters of the hazard field, such as radiation intensity, range, etc., and solving it through the radiation damage estimation module. After the solution is completed, the hazard situation display module also performs a visual display to construct the corresponding hazard field. After the virtual hazard environment is constructed, the basic data of the intelligent simulation perception terminal needs to be set and collected through the device terminal management module. These data include the terminal ID, location, sensor type, etc.

[0117] Finally, the basic data management module is used to modify and update user information and scene files. This includes operations such as adding new users, deleting old users, updating user permissions, and adding, deleting, modifying, and checking scene files. These operations help ensure the security and flexibility of the training system.

[0118] In summary, the training preparation stage of step 301 is the foundation and key of the entire nuclear radiation reconnaissance training process. Through the work of this stage, a realistic virtual nuclear radiation hazard environment can be constructed to provide strong support for subsequent training.

[0119] Step 302, training implementation phase.

[0120] In the embodiment of the present application, step 302, i.e., the training implementation phase, is a key link in the entire training process. The main task of this phase is to carry out emergency simulation reconnaissance training through the intelligent simulation perception terminal.

[0121] Specifically, the solution data generated by the radiation damage estimation module is sent to the intelligent simulation perception terminal through the interactive data distribution module. Through the wireless module, the portable communication terminal receives the task instructions forwarded by the communication base station. According to the task instructions, the portable communication terminal transmits the hazard field data in the hazard field. These data may include radiation intensity, radiation type, ambient temperature, humidity, etc.

[0122] The collected hazard field data is transmitted to the communication base station through the LoRa wireless transmission channel. LoRa technology has the advantages of long transmission distance and low power consumption, which is very suitable for such training scenarios. After receiving the hazard field data sent by the portable communication terminal, the communication base station forwards it to the control terminal. The control terminal updates the hazard field visualization display in real time through the hazard situation display module based on the received data.

[0123] The control terminal determines whether the hazard field data exceeds the preset threshold based on the received hazard field data. This step is crucial to ensure training safety. If the hazard field data exceeds the preset threshold, the control terminal will send a warning signal through the intelligent simulation perception terminal. This can remind the trainers to take timely measures to avoid potential dangers. The intelligent simulation perception terminal will also send its location and status information to the control terminal based on GPS or Beidou positioning. This information helps trainers understand the operating status of the equipment and the progress of training.

[0124] According to the preset training goals and requirements, determine whether the training is completed. If completed, enter the next step of data preservation and analysis and processing. If the training is completed, the control terminal will save the training data and perform data analysis and processing through the basic data management module. These analysis results can be used to evaluate the training effect, optimize the training plan, etc.

[0125] If the training is not completed, repeat the above steps until the preset training goals and requirements are achieved.

[0126] In summary, step 302, i.e., the training implementation phase, is a crucial link in nuclear radiation reconnaissance training. Through the operation and data processing of this phase, the reconnaissance capability in a nuclear radiation environment can be simulated, providing strong support for subsequent evaluation and actual combat application.

[0127] Step 303, training evaluation phase.

[0128] In the embodiment of the present application, step 303 is the training evaluation stage, which mainly focuses on summarizing and evaluating the training process.

[0129] Specifically, the hazard situation display module plays a vital role in this stage. It uses the data collected during the training process to perform visualization configuration and intuitively display the changes in the hazard field during the training process. This visualization not only helps trainers clearly understand the dynamics of the hazard field during the training process, but also provides strong data support for subsequent evaluations.

[0130] The device terminal management module and basic data management module in the virtual hazard environment construction unit jointly participate in the comprehensive evaluation of training data. The device terminal management module is responsible for collecting and managing data from intelligent simulation perception terminals, portable communication terminals and other devices to ensure the integrity and accuracy of the data. The basic data management module is responsible for managing and updating user information and scenario files to provide necessary background information for the evaluation.

[0131] During the comprehensive evaluation process, the two modules will work together to conduct in-depth analysis of the training data and evaluate whether the training effect has achieved the expected goal. The evaluation content may include the simulation accuracy of the hazard field, the response speed of the intelligent simulation perception terminal, the data transmission stability of the portable communication terminal, and many other aspects.

[0132] The evaluation results will be displayed through the hazard situation display module. In this way, the trainers can intuitively see the evaluation results and understand the advantages and disadvantages of the training process. Based on the evaluation results, the trainers can further adjust the training plan, optimize the training process, and improve the training effect.

[0133] When the evaluation results meet the preset standards and the trainers believe that the training has achieved the expected goals, the nuclear radiation reconnaissance training can be ended. At this time, the trainers will save the training data for subsequent analysis and summary. At the same time, they will also summarize the experience and lessons learned during the training process to provide reference for future training.

[0134] In summary, the training evaluation phase of step 303 ensures the effectiveness and pertinence of the training through steps such as visualization configuration and display, comprehensive data evaluation, and display of evaluation results and completion of training.
