Description

A radiation monitoring system and method for nuclear power plants Technical Field

[0001] This invention relates to the field of radiation monitoring technology, and in particular to a radiation monitoring system and method for nuclear power plants. Background Technology

[0002] During the operation of a nuclear power plant, the radiation status of different areas within the radiation control zone varies due to factors such as changes in unit operating status, equipment condition, corrosion activation products, and maintenance activities. To evaluate the radiation status of each area within the radiation control zone and provide data support for occupational risk analysis, radiation protection assessment, and occupational exposure evaluation for workers, workplace radiation monitoring is necessary. Current radiation monitoring methods primarily involve installing fixed radiation monitoring equipment within the workplace and manually recording the monitoring results at regular intervals to determine the presence of radiation risks.

[0003] However, existing radiation monitoring methods rely heavily on paper records or manual data entry, resulting in low information update efficiency and an inability to achieve real-time monitoring of radiation from nuclear power plants, posing significant safety risks. Therefore, improvements are needed.

[0004] Summary of the Invention

[0005] In view of the shortcomings of the prior art described above, the purpose of this invention is to provide a nuclear power plant radiation monitoring system and method that can realize real-time monitoring of nuclear power plant radiation.

[0006] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0007] This invention provides a radiation monitoring system for nuclear power plants, comprising:

[0008] At least one radiation monitoring device;

[0009] A central control platform is communicatively connected to the radiation monitoring equipment. The central control platform includes a data acquisition module, an analysis and judgment module, and an alert module.

[0010] At least one intelligent display terminal is communicatively connected to the central control platform;

[0011] The data acquisition module is used to acquire the monitoring information of the radiation monitoring equipment, and to parse and process it to generate parsed information;

[0012] The analysis and judgment module is used to perform statistical analysis on the parsed information, generate statistical analysis data, and generate a reminder instruction when the statistical analysis data is within a preset range;

[0013] The warning and reminder module is used to process the reminder instruction and generate warning information;

[0014] The intelligent display terminal is used to display the warning information and generate timed analysis reports based on the statistical analysis data.

[0015] In one embodiment of the present invention, the radiation monitoring equipment is one or more of the following: a fixed area dose rate monitor, a portable dose rate monitor, a surface contamination monitoring device, a fixed airborne radioactivity monitor, a mobile airborne radioactivity monitor, and an airborne radioactivity sampling device.

[0016] In one embodiment of the present invention, the radiation monitoring device is provided with a positioning module and a short-term storage module. The positioning module is used to obtain its own positioning information, and the short-term storage module is used to store the monitoring information.

[0017] In one embodiment of the present invention, the radiation monitoring device is connected to the central control platform via wired and / or wireless communication. When the radiation monitoring device is connected to the central control platform via wireless communication, the radiation monitoring device is equipped with a communication module for sending the monitoring information to the central control platform.

[0018] In one embodiment of the present invention, the communication module is one or more of a 4G module, a 5G module, and a WIFI module.

[0019] In one embodiment of the present invention, the central control platform further includes a data storage module for storing the parsed information and providing a database for the analysis and judgment module.

[0020] In one embodiment of the present invention, the monitoring information includes equipment information, radiation type information, location information, and time information, wherein the radiation type information is at least one of regional dose rate, surface contamination activity, and airborne radioactivity concentration.

[0021] In one embodiment of the present invention, the preset range is divided into multiple consecutive alarm ranges. When the statistical analysis data is located in different alarm ranges, the analysis and judgment module generates different levels of reminder instructions to control the warning reminder module to generate different levels of warning information.

[0022] In one embodiment of the present invention, the preset range is divided into a first alarm range, a second alarm range, and a third alarm range. When the analysis and judgment module determines that the statistical analysis data is within the first alarm range, the action performed is to generate a pop-up reminder instruction and control the warning reminder module to send a pop-up warning message to the smart display terminal.

[0023] When the analysis and judgment module determines that the statistical analysis data is within the second alarm range, the action performed is to generate a flashing light reminder command and control the warning reminder module to generate a flashing light warning message;

[0024] When the analysis and judgment module determines that the statistical analysis data is within the third alarm range, the action performed is to generate a ringing reminder command and control the warning reminder module to generate a ringing warning message.

[0025] In one embodiment of the present invention, when the monitored information is the regional dose rate, the preset range is 2-100 μSv / h, the first alarm range is 2-10 μSv / h, the second alarm range is 10-20 μSv / h, and the third alarm range is 20-100 μSv / h.

[0026] When the monitored information is surface contamination activity, the preset range is 0.04 Bq / cm³. 3 -40Bq / cm 3 The first alarm range is 0.04 Bq / cm². 3 -0.4 Bq / cm 3 The second alarm range is 0.4 Bq / cm². 3 -4Bq / cm 3 The first alarm range is 4 Bq / cm 3 -40Bq / cm 3 ;

[0027] When the monitored information is airborne radioactivity concentration, the airborne radioactivity concentration is one or more of the following: inert gas radioactivity concentration, aerosol radioactivity concentration, and radioactive iodine activity concentration. When the monitored information is inert gas radioactivity concentration, the preset range is 3.7 × 10⁻⁶. 5 Bq / m 3 -3.7×10 8 Bq / m 3 The first alarm range is 3.7 × 10 5 Bq / m 3 -3.7×10 6 Bq / m 3 The second alarm range is 3.7 × 10 6 Bq / m 3 -3.7×10 7 Bq / m 3 The third alarm range is 3.7 × 10⁻⁶. 7 Bq / m 3 -3.7×10 8 Bq / m 3 .

[0028] In one embodiment of the present invention, when the analysis and judgment module determines that the statistical analysis data is less than the minimum boundary value of the preset range, the action performed is to repeatedly acquire the parsed information, perform statistical analysis processing on the parsed information, generate new statistical analysis data, and repeatedly judge the new statistical analysis data until the statistical analysis data is within the preset range.

[0029] When the analysis and judgment module determines that the statistical analysis data is greater than the maximum boundary value of the preset range, the action performed is to simultaneously generate reminder instructions at all levels.

[0030] The present invention also provides a method for monitoring radiation in a nuclear power plant, comprising:

[0031] The data acquisition module obtains monitoring information from the radiation monitoring equipment, parses and processes it, and generates parsed information.

[0032] The analysis and judgment module performs statistical analysis on the parsed information to generate statistical analysis data.

[0033] The analysis and judgment module generates a reminder instruction based on the comparison between the statistical analysis data and a preset range;

[0034] The alert module processes the alert instruction and generates an alert message.

[0035] The intelligent display terminal displays the warning information and generates a timed analysis report based on the statistical analysis data.

[0036] In one embodiment of the present invention, the step of generating a reminder instruction based on the comparison of the statistical analysis data with a preset range includes:

[0037] Determine whether the statistical analysis data is within a preset range;

[0038] If the statistical analysis data is within the preset range, then the level of the statistical analysis data within the preset range is further determined to generate a corresponding level of reminder instruction;

[0039] If the statistical analysis data is greater than the maximum boundary value of the preset range, then all levels of reminder instructions will be generated simultaneously.

[0040] If the statistical analysis data is less than the minimum boundary value of the preset range, the parsed information is repeatedly acquired, statistical analysis is performed on the parsed information to generate new statistical analysis data, and the new statistical analysis data is repeatedly judged until the statistical analysis data is within the preset range.

[0041] As described above, the present invention provides a radiation monitoring system and method for nuclear power plants. By setting a data acquisition module to communicate with the radiation monitoring equipment, the system can acquire monitoring information from the radiation monitoring equipment in real time, reducing the workload of manually recording monitoring information and manually entering it into the database, and improving the efficiency of uploading monitoring information. By setting a data acquisition module to communicate with the analysis and judgment module, the system can provide real-time reminders of radiation monitoring results, reducing safety hazards. By setting an intelligent display terminal to communicate with the analysis and judgment module and the warning reminder module respectively, the system can display timed analysis reports and warning information in real time, allowing staff to observe the timed analysis reports and whether warning information has appeared, thereby realizing real-time monitoring of radiation in nuclear power plants.

[0054] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0055] Referring to Figure 1, this invention provides a nuclear power plant radiation monitoring system, which can be applied to radiation monitoring in nuclear power plants to achieve real-time uploading and updating of radiation monitoring data within the nuclear power plant, thereby realizing real-time monitoring of radiation in the nuclear power plant. The nuclear power plant radiation monitoring system may include, but is not limited to, radiation monitoring equipment 110, a central control platform 120, and an intelligent display terminal 130. At least one radiation monitoring device 110 may be installed to monitor various data within the nuclear power plant to obtain monitoring information. The radiation monitoring equipment 110 can be classified according to its monitoring function as dose rate monitoring equipment 111, surface contamination monitoring equipment 112, and airborne radioactivity monitoring equipment 113.

[0056] Furthermore, the dose rate monitoring device 111 can be used to monitor the regional dose rate within the working area, and the dose rate monitoring device 111 may include, but is not limited to, a fixed regional dose rate monitor 1111 and a portable dose rate monitor 1112. The portable dose rate monitor 1112 can be categorized into a portable gamma dose rate monitor, a long-rod dose rate monitor, and a portable neutron dose rate monitor. However, it is not limited to these categories; the portable dose rate monitor 1112 may also include other types of dose rate monitors. Specifically, the portable gamma dose rate monitor can be used to monitor the dose rate of gamma rays, that is, the radiation level of gamma radiation. The long-rod dose rate monitor has an extended rod-like structure, allowing the operator to perform dose rate monitoring at a greater distance; it is typically used in environments with high radiation levels, such as nuclear power plants, nuclear accident sites, or other locations requiring radiation monitoring. The portable neutron dose rate monitor can be used to monitor the dose rate of neutron radiation. A neutron is a neutral particle that typically occurs in nuclear reactions, such as nuclear fusion or nuclear fission.

[0057] Furthermore, the surface contamination monitoring device 112 can be used to monitor contamination on surfaces such as equipment surfaces, workbenches, floors, and walls in the controlled area that may be contaminated with radioactivity. The airborne radioactivity monitoring device 113 can be used to sample and monitor gases in areas with airborne contamination. The airborne radioactivity monitoring device 113 can be classified into a fixed airborne radioactivity monitor 1131, a mobile airborne radioactivity monitor 1132, and an airborne radioactivity sampling device 1133.

[0058] Among them, the fixed airborne radioactivity monitor 1131 can be set up in a fixed location, usually in factories, laboratories, nuclear power plants, etc., to continuously monitor the concentration of radioactive substances in the air, as well as any radioactive gases that may be present.

[0059] The mobile airborne radioactivity monitor 1132 can be carried to different locations for monitoring, and is used for rapid monitoring and assessment of workplaces, accident sites, or other locations where radioactive contamination may exist. This helps to determine the location and extent of the contamination source, facilitating appropriate response measures. The mobile airborne radioactivity monitor 1132 may include, but is not limited to, mobile inert gas monitors, mobile aerosol monitors, and mobile iodine monitors, which can be used to monitor the radioactivity concentration of inert gases, aerosols, or radioactive iodine in areas with airborne contamination risk, respectively.

[0060] The airborne radioactive sampling device 1133 is used to collect air from areas where radioactive gases are present for subsequent laboratory analysis. The purpose of the airborne radioactive sampling device 1133 is to collect potential radioactive contaminants for further analysis and evaluation.

[0061] It is worth further clarification that the monitoring information generated by the radiation monitoring device 110 may include, but is not limited to, device information, radiation type information, location information, and time information. The device information may include the coding information and technical parameter information corresponding to the radiation monitoring device 110, thereby determining the type of the radiation monitoring device 110 and the corresponding radiation monitoring type based on the coding information and technical parameter information. That is, the radiation type information can be determined by different types of radiation monitoring devices 110, and the radiation type information may be at least one of regional dose rate, surface contamination activity, and airborne radioactivity concentration. The location information may include, but is not limited to, the location information of the radiation monitoring device 110 and the plant layout information of its location. The plant layout information may include, but is not limited to, a list of the number of plants, a list of each plant compartment, two-dimensional map information of each floor of the plant, and a three-dimensional map.

[0062] When radiation monitoring device 110 is a dose rate monitoring device 111, the radiation type information is the regional dose rate information. When radiation monitoring device 110 is a surface contamination monitoring device 112, the radiation type information can be the surface contamination activity information of surfaces such as equipment surfaces, workbench surfaces, floors, and walls in the control area that may be radioactively contaminated. When radiation monitoring device 110 is an airborne radioactivity monitoring device 113, the radiation type information can be airborne radioactivity concentration information.

[0063] It is worth further explaining that the radiation monitoring device 110 may be equipped with a positioning module 114 and a short-term storage module 115. The positioning module 114 can be used to obtain its own positioning information to help staff quickly screen radiation risk areas. The positioning module 114 can be a Global Positioning System (GPS) module or a local positioning module based on WIFI or Bluetooth.

[0064] The short-term storage module 115 can be used to store and back up its own monitoring information to prevent the loss of monitoring information due to poor network signal or failure of the radiation monitoring equipment 110. The short-term storage module 115 can be random access memory (RAM), cache memory, or solid-state drive (SSD). However, it is not limited to these; the short-term storage module 115 can also be other storage modules, as long as they can meet the requirements for storing and backing up the monitoring information.

[0065] In one embodiment of the present invention, referring to FIG1, six radiation monitoring devices 110 may be provided, and the six radiation monitoring devices 110 may be respectively a fixed area dose rate monitor 1111, a portable dose rate monitor 1112, a surface contamination monitoring device 112, a fixed airborne radioactivity monitor 1131, a mobile airborne radioactivity monitor 1132, and an airborne radioactivity sampling device 1133. In addition, each of the six radiation monitoring devices 110 may be equipped with a positioning module 114 and a short-term storage module 115.

[0066] In addition to their respective equipment information, location information, and time information, the monitoring information generated by different radiation monitoring devices 110 may also include their respective radiation type information. Specifically, the radiation type information acquired by the fixed area dose rate monitor 1111 and the portable dose rate monitor 1112 is area dose rate information. The radiation type information acquired by the surface contamination monitoring device 112 is surface contamination activity information. The radiation type information acquired by the fixed airborne radioactivity monitor 1131, the mobile airborne radioactivity monitor 1132, and the airborne radioactivity sampling device 1133 is airborne radioactivity concentration information.

[0067] Please refer to Figures 1 and 2. The central control platform 120 can be a cloud server, and the central control platform 120 can communicate with the radiation monitoring device 110 to receive the monitoring information uploaded by the radiation monitoring device 110, and process the monitoring information to generate warning information.

[0068] The radiation monitoring device 110 and the central control platform 120 can be connected via wired and / or wireless communication. When the radiation monitoring device 110 and the central control platform 120 are connected via wireless communication, a communication module 116 can be installed inside the radiation monitoring device 110 to send monitoring information to the central control platform 120. The communication module 116 can be one or more of a 4G module, a 5G module, and a WIFI module.

[0069] When the radiation monitoring device 110 and the central control platform 120 are connected via wired communication, the wired communication connection methods may include, but are not limited to, Ethernet wired communication connection, serial communication connection, and USB (Universal Serial Bus) communication connection. Ethernet is a widely used wired communication standard in local area networks (LANs), which can use transmission media such as twisted-pair cables or optical fibers, providing high-speed and stable data transmission. Serial communication is a communication method that transmits data bit by bit; serial communication protocols may include RS-232, RS-485, and CAN bus. USB is a common universal interface standard suitable for short-distance data transmission.

[0070] In one embodiment of the present invention, referring to FIG2, when the radiation monitoring device 110 includes a fixed area dose rate monitor 1111, a portable dose rate monitor 1112, a surface contamination monitoring device 112, a fixed airborne radioactivity monitor 1131, a mobile airborne radioactivity monitor 1132, and an airborne radioactivity sampling device 1133, the fixed area dose rate monitor 1111, the fixed airborne radioactivity monitor 1131, and the airborne radioactivity sampling device 1133 can be wired to the central control platform 120, and the portable dose rate monitor 1112, the surface contamination monitoring device 112, and the mobile airborne radioactivity monitor 1132 can be respectively equipped with a communication module 116 to realize wireless communication connection with the central control platform 120.

[0071] Please refer to Figure 2. The central control platform 120 may be equipped with a data acquisition module 121, an analysis and judgment module 122, and an alarm and reminder module 123. When the radiation monitoring device 110 and the central control platform 120 are connected via wired communication, the data acquisition module 121 can communicate with the radiation monitoring device 110 to collect monitoring information from the device. This reduces the workload of manually recording measurement results and manually entering them into the database, improving the efficiency and accuracy of uploading and storing monitoring information.

[0072] However, this is not the only limitation. When the radiation monitoring device 110 and the central control platform 120 are connected by wireless communication, the data acquisition module 121 can communicate with the communication module 116 in the radiation monitoring device 110 to collect and acquire the monitoring information of the radiation monitoring device 110.

[0073] Furthermore, the data acquisition module 121 may include interface program units for various radiation monitoring devices 110 to parse and process the monitoring information sent by the radiation monitoring devices 110, generate parsed information, and upload the parsed information to the analysis and judgment module 122.

[0074] The analysis and judgment module 122 is communicatively connected to the data acquisition module 121 to perform statistical analysis on the parsed information in the data acquisition module 121, generating statistical analysis data. This statistical analysis data may include, but is not limited to, trend data on regional dose rate, airborne radioactivity concentration, and surface contamination activity within a specified area over a specific time period (single, daily, weekly, monthly, yearly, etc.). However, it is not limited to this; the analysis and judgment module 122 also determines whether the statistical analysis data falls within a preset range and generates an alert command to remind staff of potential radiation safety hazards, ensuring that nuclear power plant workers are protected from unnecessary radiation.

[0075] Furthermore, the analysis and judgment module 122 can determine whether the statistical analysis data is within a preset range to decide whether to generate an alert instruction. If the statistical analysis data is less than the minimum boundary value within the preset range, the parsed information in the data acquisition module 121 needs to be repeatedly acquired, and the statistical analysis processing on the parsed information needs to be repeated to generate new statistical analysis data. The new statistical analysis data is then repeatedly judged until the statistical analysis data is within the preset range. If the statistical analysis data is greater than the maximum boundary value within the preset range, the analysis and judgment module 122 generates alert instructions at all levels simultaneously and uploads all levels of alert instructions to the warning and alert module 123 to control the warning and alert module 123 to generate warning information at all levels accordingly.

[0076] In one embodiment of the present invention, the preset range can be divided into multiple consecutive alarm ranges, and when the statistical analysis data falls within different alarm ranges, the analysis and judgment module 122 can generate different levels of alert instructions to control the warning alert module 123 to generate corresponding levels of warning information. For example, the preset range can be divided into a first alarm range, a second alarm range, and a third alarm range. However, it is not limited to this; the preset range can also be divided into other numbers of alarm ranges. The alert instructions may include, but are not limited to, pop-up alert instructions, flashing light alert instructions, and ringing alert instructions.

[0077] When the analysis and judgment module 122 determines that the statistical analysis data is within the first alarm range, its action can be to generate a pop-up reminder command. When the analysis and judgment module 122 determines that the statistical analysis data is within the second alarm range, its action can be to generate a flashing light reminder command. When the analysis and judgment module 122 determines that the statistical analysis data is within the third alarm range, its action can be to generate a ringing reminder command. However, it is not limited to these actions; when the analysis and judgment module 122 determines that the statistical analysis data is within other alarm ranges, its action can be to generate other corresponding reminder commands.

[0078] Furthermore, when the statistical analysis data is determined to be the minimum or maximum boundary value of the first alarm range, the statistical analysis data can be defined as being within the first alarm range. When the statistical analysis data is the maximum boundary value of the second alarm range, the statistical analysis data can be defined as being within the second alarm range. When the statistical analysis data is the maximum boundary value of the third alarm range, the statistical analysis data can be defined as being within the third alarm range.

[0079] It is worth further clarification that the preset range can be determined based on the radiation type information in the monitoring data, and the corresponding preset range will also be different when the radiation type information is different. For example, when the radiation type information in the monitoring data is regional dose rate, the preset range can be 2-100 μSv / h, the first alarm range can be 2-10 μSv / h, the second alarm range can be 10-20 μSv / h, and the third alarm range can be 20-100 μSv / h. Among these, when the monitoring data is regional dose rate, and the statistical analysis data is 2 μSv / h or 10 μSv / h, it can be classified as the first alarm range; when the statistical analysis data is 20 μSv / h, it can be classified as the second alarm range; and when the statistical analysis data is 10 μSv / h, it can be classified as the third alarm range.

[0080] When the monitoring information is surface contaminant activity, the preset range can be 0.04 Bq / cm³. 3 -40Bq / cm 3 And the first alarm range is 0.04 Bq / cm².3 -0.4 Bq / cm 3 The second alarm range is 0.4 Bq / cm². 3 -4Bq / cm 3 The first alarm range is 4 Bq / cm². 3 -40Bq / cm 3 Among them, when the monitoring information is surface contamination activity, and when the statistical analysis data is 0.04 Bq / cm³, the monitoring information is considered to be surface contamination activity. 3 Or 0.4 Bq / cm 3 When this occurs, it can be categorized into the first alarm range, and when the statistical analysis data is 4 Bq / cm³. 3 When this occurs, it can be categorized as the second alarm range, and when the statistical analysis data is 40 Bq / cm³. 3 In this case, it can be classified as the third alarm range.

[0081] When the monitored information is the concentration of airborne radioactivity, the airborne radioactivity concentration may include, but is not limited to, one or more of the following: the radioactivity concentration of inert gas, the radioactivity concentration of aerosol, and the radioactive iodine activity concentration. When the airborne radioactivity concentration is the radioactivity concentration of inert gas, its corresponding preset range can be 3.7 × 10⁻⁶. 5 Bq / m 3 -3.7×10 8 Bq / m 3 Furthermore, the first alarm range can be 3.7 × 10⁻⁶. 5 Bq / m 3 -3.7×10 6 Bq / m 3 The second alarm range can be 3.7 × 10 6 Bq / m 3 -3.7×10 7 Bq / m 3 The third alarm range can be 3.7 × 10 7 Bq / m 3 -3.7×10 8 Bq / m 3 Among them, when the monitored information is the radioactivity concentration of inert gas, and when the statistical analysis data is 3.7 × 10⁻⁶, the monitoring information is considered to be of the highest quality. 5 Bq / m 3 Or 3.7×10 6 Bq / m 3 When this occurs, it can be categorized into the first alarm range, and when the statistical analysis data is 3.7 × 10⁻⁶. 7 Bq / m 3 When this occurs, it can be categorized as the second alarm range, and when the statistical analysis data is 3.7 × 10⁻⁶. 8 Bq / m 3 In this case, it can be classified as the third alarm range.

[0082] In one embodiment of the present invention, the warning and reminder module 123 can be communicatively connected to the analysis and judgment module 122 to perform reminder processing according to the reminder instructions generated by the analysis and judgment module 122, so as to generate corresponding warning information. The warning information may include, but is not limited to, pop-up warning information, flashing light warning information, and ringing warning information, and the warning information can be determined according to the reminder instructions generated by the analysis and judgment module 122.

[0083] For example, when the analysis and judgment module 122 determines that the statistical analysis data is within the first alarm range, its action is to generate a pop-up reminder instruction and send it to the warning reminder module 123. When the warning reminder module 123 determines that it has received the pop-up reminder instruction, its action is to process the pop-up reminder according to the pop-up reminder instruction to generate a pop-up warning message.

[0084] When the analysis and judgment module 122 determines that the statistical analysis data is within the second alarm range, its action is to generate a flashing light reminder command and send it to the warning reminder module 123. When the warning reminder module 123 determines that it has received the flashing light reminder command, its action is to perform flashing light reminder processing according to the flashing light reminder command and generate flashing light reminder information.

[0085] When the analysis and judgment module 122 determines that the statistical analysis data is within the third alarm range, its action is to generate a ringing reminder command and send it to the warning reminder module 123. When the warning reminder module 123 determines that it has received the ringing reminder command, its action is to perform ringing reminder processing according to the ringing reminder command and generate ringing reminder information.

[0086] Please refer to Figure 2. The central control platform 120 may also be equipped with a data storage module 124. The data storage module 124 can be connected to the data acquisition module 121 and the analysis and judgment module 122 respectively to store the parsed information in the data acquisition module 121 and provide a database for the analysis and judgment module 122.

[0087] At least one intelligent display terminal 130 can be configured, and the intelligent display terminal 130 can communicate with the central control platform 120 to display warning information from the central control platform 120, and generate timed analysis reports based on statistical analysis data for real-time display. Specifically, the intelligent display terminal 130 can communicate with the analysis and judgment module 122 and the warning and reminder module 123 respectively. The intelligent display terminal 130 can be a computer, and it can have a display screen to display warning information and timed analysis reports. The intelligent display terminal 130 and the analysis and judgment module 122 can have a one-way or two-way communication connection. When the intelligent display terminal 130 and the analysis and judgment module 122 have a two-way communication connection, the intelligent display terminal 130 can have a graphical user interface (GUI) to receive and execute work instructions issued by the user.

[0088] In one embodiment of the present invention, referring to FIG. 2, the radiation monitoring device 110 includes a fixed area dose rate monitor 1111, a portable dose rate monitor 1112, a surface contamination monitoring device 112, a fixed airborne radioactivity monitor 1131, a mobile airborne radioactivity monitor 1132, and an airborne radioactivity sampling device 1133. Each radiation monitoring device 110 is equipped with a short-time memory module 115 and a positioning module 114. The short-time memory module 115 can be random access memory (RAM), and the positioning module 114 can be a global positioning module (GPS).

[0089] Furthermore, the fixed area dose rate monitor 1111, the fixed airborne radioactivity monitor 1131, and the airborne radioactivity sampling device 1133 are respectively connected to the data acquisition module 121 via a CAN bus to upload their monitoring information to the data acquisition module 121. The portable dose rate monitor 1112, the surface contamination monitoring device 112, and the mobile airborne radioactivity monitor 1132 may each be equipped with a communication module 116. The communication module 116 is a 4G communication module, and it is wirelessly connected to the data acquisition module 121.

[0090] Furthermore, the central control platform 120 includes a data acquisition module 121, an analysis and judgment module 122, an alert and reminder module 123, and a data storage module 124. The data acquisition module 121 collects various monitoring information from the radiation monitoring equipment 110 and analyzes and processes this information to obtain the analyzed data. The analysis and judgment module 122 is communicatively connected to the data acquisition module 121 to perform statistical analysis on the analyzed information, generate statistical analysis data, and generate an alert command when the statistical analysis data falls within a preset range.

[0091] The preset ranges are divided into a first alarm range, a second alarm range, and a third alarm range. Alarm commands include pop-up alerts, flashing light alerts, and ringing alerts. When the radiation type data within the statistical analysis data falls within the first alarm range, the analysis and judgment module 122 generates a pop-up alert. When the radiation type data within the statistical analysis data falls within the second alarm range, the analysis and judgment module 122 generates a flashing light alert. When the radiation type data within the statistical analysis data falls within the third alarm range, the analysis and judgment module 122 generates a ringing alert.

[0092] It is worth further explaining that the warning and reminder module 123 can be communicatively connected to the analysis and judgment module 122 to process reminders according to the reminder command and generate warning information. Specifically, when the reminder command is a pop-up reminder command, the warning information is a pop-up warning message. When the reminder command is a flashing light reminder command, the warning information is a flashing light warning message. When the reminder command is a ringing reminder command, the warning information is a ringing warning message.

[0093] The data storage module 124 is communicatively connected to the data acquisition module 121 to store and back up the parsed information. The data storage module 124 is also communicatively connected to the analysis and judgment module 122 to provide a database for the analysis and judgment module 122.

[0094] The intelligent display terminal 130 is a computer-based terminal, and it has a bidirectional communication connection with the analysis and judgment module 122 to obtain statistical analysis data and generate scheduled analysis reports. The intelligent display terminal 130 may also have a user interface to receive and execute user-issued work instructions. The intelligent display terminal 130 is also connected to the warning and reminder module 123 to obtain and display warning information.

[0095] Figure 3 is a flowchart of a radiation monitoring method for nuclear power plants. This method can be applied to the aforementioned monitoring system. When the monitoring method monitors the radiation monitoring system 100, the nuclear power plant radiation monitoring method may include the following steps.

[0096] Step S100: The data acquisition module acquires the monitoring information from the radiation monitoring equipment, and parses and processes it to generate parsed information.

[0097] Step S200: The analysis and judgment module performs statistical analysis on the parsed information to generate statistical analysis data.

[0098] Step S300: The analysis and judgment module generates a reminder instruction based on the comparison between statistical analysis data and a preset range.

[0099] Step S400: The warning and reminder module processes the reminder according to the reminder instruction and generates a warning message.

[0100] Step S500: The intelligent display terminal displays warning information and generates a timed analysis report based on statistical analysis data.

[0101] In one embodiment of the present invention, when step S100 is executed, specifically, the monitoring information of the radiation monitoring device 110 can be acquired by the data acquisition module 121 and parsed to obtain the parsed information. The data acquisition module 121 can be wired to the radiation monitoring device 110 to acquire the monitoring information of the radiation monitoring device 110. The wired communication connection method may include, but is not limited to, Ethernet wired communication connection, serial communication connection, and USB (Universal Serial Bus) communication connection.

[0102] Ethernet is a widely used wired communication standard for Local Area Networks (LANs). It can use transmission media such as twisted-pair cables or optical fibers, providing high-speed and stable data transmission. Serial communication is a communication method that transmits data bit by bit. Serial communication protocols can include RS-232, RS-485, and CAN bus, among others. USB is a common universal interface standard suitable for short-distance data transmission.

[0103] Furthermore, the monitoring information generated by the radiation monitoring device 110 may include, but is not limited to, device information, radiation type information, location information, and time information. The device information may include the coding information and technical parameter information corresponding to the radiation monitoring device 110, thereby determining the type of the radiation monitoring device 110 and the corresponding radiation monitoring type based on the coding information and technical parameter information. That is, the radiation type information can be determined by different types of radiation monitoring devices 110, and the radiation type information may be at least one of regional dose rate, surface contamination activity, and airborne radioactivity concentration. The location information may include, but is not limited to, the location information of the radiation monitoring device 110 and the plant layout information of its location. The plant layout information may include, but is not limited to, a list of the number of plants, a list of each plant compartment, two-dimensional map information of each floor of the plant, and a three-dimensional map.

[0104] When radiation monitoring device 110 is a dose rate monitoring device 111, the radiation type information is the regional dose rate information. When radiation monitoring device 110 is a surface contamination monitoring device 112, the radiation type information can be the surface contamination activity information of surfaces such as equipment surfaces, workbench surfaces, floors, and walls in the control area that may be radioactively contaminated. When radiation monitoring device 110 is an airborne radioactivity monitoring device 113, the radiation type information can be airborne radioactivity concentration information.

[0105] Furthermore, the data acquisition module 121 may include interface program units for various radiation monitoring devices 110 to parse and process the monitoring information sent by the radiation monitoring devices 110, generate parsed information, and upload the parsed information to the analysis and judgment module 122.

[0106] In one embodiment of the present invention, when step S200 is executed, specifically, the analysis and judgment module 122 is communicatively connected to the data acquisition module 121 to perform statistical analysis on the parsed information in the data acquisition module 121 and generate statistical analysis data. The statistical analysis data may include, but is not limited to, trend data on regional dose rate, airborne radioactivity concentration, and surface contamination activity within a specific time period (single, daily, weekly, monthly, yearly, etc.) of a specified area. However, it is not limited to this; the analysis and judgment module 122 is also used to determine whether the statistical analysis data falls within a preset range and generate a reminder instruction to alert staff to potential radiation safety hazards.

[0107] In one embodiment of the present invention, when step S300 is executed, step S300 may specifically include steps S310 to S340, as detailed below.

[0108] Step S310: Determine whether the statistical analysis data is within the preset range.

[0109] Step S320: If the statistical analysis data is within a preset range, then continue to determine the level of the statistical analysis data within the preset range in order to generate a corresponding level of reminder instruction.

[0110] Step S330: If the statistical analysis data is greater than the maximum boundary value of the preset range, then all levels of reminder instructions will be generated simultaneously.

[0111] Step S340: If the statistical analysis data is less than the minimum boundary value of the preset range, the parsed information is repeatedly obtained, the parsed information is statistically analyzed and processed to generate new statistical analysis data, and the new statistical analysis data is repeatedly judged until the statistical analysis data is within the preset range.

[0112] In one embodiment of the present invention, when steps S310 to S340 are executed, specifically, the analysis and judgment module 122 can determine whether the statistical analysis data is within a preset range to determine whether to generate an alert instruction. If the statistical analysis data is less than the minimum boundary value within the preset range, the parsed information in the data acquisition module 121 needs to be repeatedly acquired, the parsed information is repeatedly subjected to statistical analysis processing to generate new statistical analysis data, and the new statistical analysis data is repeatedly judged until the statistical analysis data is within the preset range. If the statistical analysis data is greater than the maximum boundary value within the preset range, the analysis and judgment module 122 generates alert instructions at all levels simultaneously and uploads all levels of alert instructions to the warning and reminder module 123.

[0113] Furthermore, the preset range can be divided into multiple consecutive alarm ranges, and when the statistical analysis data falls within different alarm ranges, the analysis and judgment module 122 can generate different levels of alert instructions to control the warning module 123 to generate corresponding levels of warning information. The preset range can be divided into a first alarm range, a second alarm range, and a third alarm range. However, it is not limited to this; the preset range can also be divided into other numbers of alarm ranges. The alert instructions may include, but are not limited to, pop-up alert instructions, flashing light alert instructions, and ringing alert instructions.

[0114] When the analysis and judgment module 122 determines that the statistical analysis data is within the first alarm range, its action can be to generate a pop-up reminder command. When the analysis and judgment module 122 determines that the statistical analysis data is within the second alarm range, its action can be to generate a flashing light reminder command. When the analysis and judgment module 122 determines that the statistical analysis data is within the third alarm range, its action can be to generate a ringing reminder command. However, it is not limited to these actions; when the analysis and judgment module 122 determines that the statistical analysis data is within other alarm ranges, its action can be to generate other corresponding reminder commands.

[0115] Specifically, when the statistical analysis data is the minimum or maximum boundary value of the first alarm range, the statistical analysis data can be defined as being within the first alarm range. When the statistical analysis data is the maximum boundary value of the second alarm range, the statistical analysis data can be defined as being within the second alarm range. When the statistical analysis data is the maximum boundary value of the third alarm range, the statistical analysis data can be defined as being within the third alarm range.

[0116] It is worth further clarification that the preset range can be determined based on the radiation type information in the monitoring data, and the corresponding preset range will also be different when the radiation type information is different. For example, when the radiation type information in the monitoring data is regional dose rate, the preset range can be 2-100 μSv / h, the first alarm range can be 2-10 μSv / h, the second alarm range can be 10-20 μSv / h, and the third alarm range can be 20-100 μSv / h. Among these, when the monitoring data is regional dose rate, and the statistical analysis data is 2 μSv / h or 10 μSv / h, it can be classified as the first alarm range; when the statistical analysis data is 20 μSv / h, it can be classified as the second alarm range; and when the statistical analysis data is 10 μSv / h, it can be classified as the third alarm range.

[0117] When the monitoring information is surface contaminant activity, the preset range can be 0.04 Bq / cm³. 3 -40Bq / cm 3 And the first alarm range is 0.04 Bq / cm². 3 -0.4 Bq / cm 3 The second alarm range is 0.4 Bq / cm². 3 -4Bq / cm 3 The first alarm range is 4 Bq / cm². 3 -40Bq / cm 3 Among them, when the monitoring information is surface contamination activity, and when the statistical analysis data is 0.04 Bq / cm³, the monitoring information is considered to be surface contamination activity. 3 Or 0.4 Bq / cm 3 When this occurs, it can be categorized into the first alarm range, and when the statistical analysis data is 4 Bq / cm³. 3 When this occurs, it can be categorized as the second alarm range, and when the statistical analysis data is 40 Bq / cm³. 3 In this case, it can be classified as the third alarm range.

[0118] When the monitored information is the concentration of airborne radioactivity, the airborne radioactivity concentration may include, but is not limited to, one or more of the following: the radioactivity concentration of inert gas, the radioactivity concentration of aerosol, and the radioactive iodine activity concentration. When the airborne radioactivity concentration is the radioactivity concentration of inert gas, its corresponding preset range can be 3.7 × 10⁻⁶. 5 Bq / m 3 -3.7×10 8 Bq / m 3 Furthermore, the first alarm range can be 3.7 × 10⁻⁶. 5 Bq / m 3 -3.7×10 6 Bq / m 3 The second alarm range can be 3.7 × 106 Bq / m 3 -3.7×10 7 Bq / m 3 The third alarm range can be 3.7 × 10 7 Bq / m 3 -3.7×10 8 Bq / m 3 .

[0119] Among them, when the monitored information is the concentration of radioactive inert gas, and when the statistical analysis data is 3.7 × 10⁻⁶, the monitoring information is considered to be the concentration of radioactive inert gas. 5 Bq / m 3 Or 3.7×10 6 Bq / m 3 When this occurs, it can be categorized into the first alarm range, and when the statistical analysis data is 3.7 × 10⁻⁶. 7 Bq / m 3 When this occurs, it can be categorized as the second alarm range, and when the statistical analysis data is 3.7 × 10⁻⁶. 8 Bq / m 3 In this case, it can be classified as the third alarm range.

[0120] In one embodiment of the present invention, when step S400 is executed, specifically, the warning and reminder module 123 can be communicatively connected to the analysis and judgment module 122 to perform reminder processing based on the reminder instructions generated by the analysis and judgment module 122, so as to generate warning information. The warning information may include, but is not limited to, pop-up warning information, flashing light warning information, and ringing warning information, and the warning information can be determined based on the reminder instructions generated by the analysis and judgment module 122.

[0121] For example, when the analysis and judgment module 122 determines that the statistical analysis data is within the first alarm range, its action is to generate a pop-up reminder instruction and send it to the warning reminder module 123. When the warning reminder module 123 determines that it has received the pop-up reminder instruction, its action is to process the pop-up reminder according to the pop-up reminder instruction to generate a pop-up warning message.

[0122] When the analysis and judgment module 122 determines that the statistical analysis data is within the second alarm range, its action is to generate a flashing light reminder command and send it to the warning reminder module 123. When the warning reminder module 123 determines that it has received the flashing light reminder command, its action is to perform flashing light reminder processing according to the flashing light reminder command and generate flashing light reminder information.

[0123] When the analysis and judgment module 122 determines that the statistical analysis data is within the third alarm range, its action is to generate a ringing reminder command and send it to the warning reminder module 123. When the warning reminder module 123 determines that it has received the ringing reminder command, its action is to perform ringing reminder processing according to the ringing reminder command and generate ringing reminder information.

[0124] In one embodiment of the present invention, when step S500 is executed, specifically, at least one intelligent display terminal 130 may be provided, and the intelligent display terminal 130 may be communicatively connected to the central control platform 120 to display warning information from the central control platform 120, and generate timed analysis reports based on statistical analysis data for real-time display. Specifically, the intelligent display terminal 130 may be communicatively connected to the analysis and judgment module 122 and the warning and reminder module 123 respectively. The intelligent display terminal 130 may be a computer, and a display screen may be provided within the intelligent display terminal 130 to display warning information and timed analysis reports. The intelligent display terminal 130 and the analysis and judgment module 122 may have a one-way communication connection or a two-way communication connection. When the intelligent display terminal 130 and the analysis and judgment module 122 have a two-way communication connection, the intelligent display terminal 130 may be provided with a graphical user interface (GUI) to receive and execute work instructions issued by the user.

[0125] In summary, the nuclear power plant radiation monitoring system and method provided by this invention, by setting up a data acquisition module to communicate with the radiation monitoring equipment, can acquire monitoring information from the radiation monitoring equipment in real time, reduce the workload of manually recording monitoring information and manually entering it into the database, avoid the problem of data saving errors due to manual recording mistakes, and improve the uploading efficiency of monitoring information.

[0126] By setting up a communication connection between the data acquisition module and the analysis and judgment module, monitoring information can be uploaded to the analysis and judgment module for sequential parsing and judgment processing to generate corresponding alert instructions. These alert instructions then control the warning module to generate corresponding warning information, thereby achieving real-time alerts for radiation monitoring and reducing safety hazards.

[0127] Simultaneously, by establishing a communication connection between the intelligent display terminal and the analysis and judgment module, regular analysis reports can be generated based on the statistical analysis data from the analysis and judgment module. Furthermore, by establishing a communication connection between the intelligent display terminal and the warning and reminder module, warning information can be displayed in real time, allowing staff to observe the regular analysis reports and whether warning messages have appeared, thus achieving real-time monitoring of radiation from the nuclear power plant. Further, staff can also quickly locate radiation sources by observing the location information in the regular analysis reports on the intelligent display terminal, facilitating timely control of radiation risks.
