[0002] Radioactive radiation detection devices are used to assess the level of radioactivity at different locations within a power plant, ensuring personnel are protected from hazards caused by abnormal conditions and to monitor the post-accident status. In some work areas, the dose rate is normally low, but may suddenly increase by orders of magnitude, affecting the residence of workers. It is necessary to continuously measure the dose rate of the radiation signal, and to issue audible and visual alarm signals when the radioactivity level or dose rate exceeds a preset threshold.

[0003] Radioactive radiation detection devices in related technologies (such as common gamma radiation monitoring devices in nuclear power plants) have relatively limited measurement ranges.

[0073] Radioactive radiation detection devices are used to assess the level of radioactivity at different locations within a power plant, ensuring personnel are protected from hazards caused by abnormal conditions and to monitor the post-accident status. In some work areas, the dose rate is normally low, but may suddenly increase by orders of magnitude, affecting the residence of workers. It is necessary to continuously measure the dose rate of the radiation signal, and to issue audible and visual alarm signals when the radioactivity level or dose rate exceeds a preset threshold.

[0074] First, a major problem faced by radioactive radiation detection devices in related technologies (such as common gamma radiation monitoring devices in nuclear power plants) is the limitation of signal and information transmission methods. These radioactive radiation detection devices typically include components such as radiation detectors, local processing and display units (LPDUs), and electrical connection boxes.

[0075] The function of a radiation detector is to convert radiation information into electrical signals through probes that can interact with the received radiation.

[0076] LPDU refers to the Local Processing and Display Unit, a crucial component of radiation signal monitoring systems in nuclear power plants. The primary function of the LPDU is to receive signals from radiation detectors, process the data to obtain digital or analog information, and then send this information to higher-level systems for further analysis and operation. LPDUs typically include data processing, display, and alarm functions, enabling on-site monitoring and preliminary processing of detected signals. The LPDU is responsible for receiving and processing detected signals, deriving measured values, and issuing audible and visual alarms when preset thresholds are exceeded or when a malfunction occurs.

[0077] The electrical connection box connects to the LPDU and, via power and communication cables, to the nuclear power plant's distributed control system (DCS), enabling centralized monitoring of the monitoring channels. The DCS, also known as a distributed control system, is a multi-level computer system integrating computer, communication, display, and control technologies. Its core concept is distributed control and centralized management.

[0078] However, there are several major technical problems in implementing these functions:

[0079] First, the radioactive radiation detection devices in the relevant technologies cannot be directly matched with systems based on bus transmission technology, which limits the compatibility and scalability of the monitoring devices.

[0080] Secondly, existing radiation detectors have limited measurement ranges. To adapt to different monitoring needs, they often need to be adapted within a certain range, or different types of radiation detectors and detection elements need to be used for different monitoring needs, which increases complexity and cost.

[0081] In addition, the existing radiation detectors are relatively complex in configuration and have many interfaces, which requires a certain amount of space for on-site setup and also brings a large workload to the installation and maintenance personnel.

[0082] In summary, radioactive radiation detection devices in related technologies face challenges in monitoring the radioactive environment of nuclear power plants, including signal transmission mismatch, limited measurement range, and complex configuration. These issues not only affect the performance and reliability of the monitoring devices but also increase operation and maintenance costs and difficulties.

[0083] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a radiation signal monitoring device and method for nuclear power plants, electronic equipment, and storage medium, which can effectively collect radiation signals over a wide range without significantly increasing complexity and cost.

[0084] The following explanation is based on the accompanying drawings.

[0085] Referring to FIG1A, a nuclear power plant radiation signal monitoring device according to an embodiment of this application may include:

[0086] The power module is used to provide input voltage to the radiation signal monitoring device in the nuclear power plant;

[0087] It should be noted that the power module is the foundation of the entire monitoring device, responsible for providing a stable input voltage to the nuclear power plant radiation signal monitoring equipment. The design of the power module needs to take into account the electromagnetic interference and power fluctuations that may exist in the nuclear power plant environment to ensure that the monitoring device can operate stably under various conditions.

[0088] In some more specific embodiments, the power module can be one of three types of power sources: a linear regulated power supply, an external 24V input power supply, and an internal 24V output rechargeable lithium battery. The power module can be composed of structural components such as a linear power supply, a surge suppressor, a power input connector, and a voltage distribution unit.

[0089] The radiation detector includes a low-dose detection branch and a high-dose detection branch set in the target radiation monitoring field. The low-dose detection branch is equipped with a low-dose radiation-sensitive element and a low-dose signal conditioning module, and the high-dose detection branch is equipped with a high-dose radiation-sensitive element and a high-dose signal conditioning module. The low-dose detection branch is used to perform radiation detection in the low-dose radiation detection range, and the high-dose detection branch is used to perform radiation detection in the high-dose radiation range.

[0090] It should be noted that the radiation detector is the core of the monitoring device, comprising low-dose and high-dose detection branches positioned within the target radiation monitoring area. The low-dose detection branch is equipped with low-dose radiation-sensitive elements and low-dose signal conditioning modules, specifically designed for radiation detection in the low-dose radiation range. These elements and modules can detect and process weak radiation signals, ensuring accurate monitoring under normal operation or low-radiation-level conditions. The high-dose detection branch, on the other hand, is equipped with high-dose radiation-sensitive elements and high-dose signal conditioning modules for radiation detection in the high-dose radiation range. These elements and modules are designed to provide reliable monitoring data in situations of rapidly increasing radiation levels, such as nuclear accidents or leaks.

[0091] The processing and control module is used to control the radiation detector to detect the current radiation detection information using the low-dose detection branch or the high-dose detection branch, and to generate a monitoring indication signal based on the current radiation detection information;

[0092] It should be noted that the processing and control module is the intelligent center of the nuclear power plant's radiation signal monitoring device. It is responsible for controlling the switching of radiation detectors between low-dose and high-dose detection branches to adapt to current radiation detection needs. Based on the received radiation detection information, the processing and control module can generate monitoring indication signals that reflect the current radiation level and potential threats.

[0093] The monitoring indication module is used to receive monitoring indication signals from the processing control module and perform monitoring response operations based on the monitoring indication signals;

[0094] It should be noted that the monitoring indication module receives monitoring indication signals from the processing and control module and performs monitoring response operations based on these signals. This may include triggering alarms, recording data, adjusting detection parameters, or notifying operators. The monitoring indication module is designed to ensure rapid response and accurate execution, enabling timely and appropriate measures to be taken.

[0095] An integrated module is used to integrate a power supply module, a radiation detector, a processing control module, and a monitoring and indication module.

[0096] It is worth noting that the integrated module combines the power supply module, radiation detector, processing control module, and monitoring indication module into a compact and efficient nuclear power plant radiation signal monitoring device. The integrated module's design considers space optimization, component compatibility, and overall performance, ensuring the reliability and ease of use of the nuclear power plant radiation signal monitoring device.

[0097] Figure 1B shows another example of a radiation signal monitoring device for a nuclear power plant. This device can consist of multiple key modules that work together to monitor and process radiation signals. The integrated module in this embodiment integrates key components such as a power management module, processing control module, analog-to-digital conversion module, and communication module into a single unit, facilitating the management and coordination of the entire monitoring process.

[0098] The power supply module is responsible for providing a stable power supply to the entire nuclear power plant's radiation signal monitoring device, while the power management module is responsible for converting this power into the specific voltage required by each module within this embodiment, ensuring that each component operates in its optimal state. The processing and control module is the brain of this embodiment; it receives data from the radiation detector, analyzes and processes it, generates monitoring indication signals, and controls the operation of other modules.

[0099] In this embodiment, the analog-to-digital converter (AD / DA) acts as a bridge, converting analog signals into digital signals for analysis by the processing and control module. It also converts digital signals back to analog signals for control output or driving other devices. The communication module is responsible for enabling data exchange between the monitoring device and external embodiments of this application. It may include wired or wireless communication interfaces to ensure timely transmission of monitoring data to remote monitoring embodiments or receipt of instructions from the control center.

[0100] The radiation detector is the part that directly contacts the radiation source. It includes two detection branches: a low-dose branch and a high-dose branch. Each branch is equipped with a corresponding signal conditioning module and a sensing element. The low-dose and high-dose signal conditioning modules are responsible for the preliminary processing of the low-dose and high-dose radiation-induced signals, respectively, to facilitate subsequent analog-to-digital conversion and analysis. The design of these conditioning modules ensures that the embodiments of this application can provide accurate monitoring results under different radiation levels.

[0101] The monitoring indication module performs corresponding operations based on the monitoring indication signals generated by the processing control module, such as triggering alarms, recording data, or adjusting detection parameters, to ensure timely response when radiation levels exceed preset thresholds. The communication interface is the physical interface through which the monitoring device exchanges data with other embodiments of this application. It supports multiple communication protocols to adapt to different application scenarios.

[0102] In summary, the nuclear power plant radiation signal monitoring device of this application integrates multiple functional modules to achieve comprehensive monitoring and processing of radiation signals. This design not only improves the accuracy and reliability of radiation monitoring but also enhances the flexibility and scalability of the nuclear power plant radiation signal monitoring device.

[0103] Referring to Figure 2, the nuclear power plant radiation signal monitoring method according to the embodiments of this application is applied to the nuclear power plant radiation signal monitoring device of the embodiments of this application. The nuclear power plant radiation signal monitoring method may include:

[0104] Step S201: The processing control module controls the radiation detector to select the current detection branch between the low-dose detection branch and the high-dose detection branch; wherein, the low-dose detection branch is used to perform radiation detection in the low-dose radiation detection range, and the high-dose detection branch is used to perform radiation detection in the high-dose radiation range.

[0105] Step S202: Control the current detection branch to perform radiation detection in the target radiation monitoring field through the radiation detector to obtain the corresponding current radiation detection information;

[0106] Step S203: Transmit the current radiation detection information to the processing and control module through the radiation detector;

[0107] Step S204: In the processing and control module, a monitoring indication signal is generated based on the current radiation detection information;

[0108] In step S205, the monitoring indication module receives a monitoring indication signal from the processing control module and performs a monitoring response operation based on the monitoring indication signal.

[0109] To address the limitation of measurement range in related technologies for radioactive radiation detection devices under varying monitoring requirements, the nuclear power plant radiation signal monitoring method of this application achieves wide-range radiation signal monitoring through intelligent detection and processing control, without significantly increasing system complexity and cost. This method effectively solves the technical problem of wide-range monitoring under different radiation levels through intelligent detection branch selection, real-time data acquisition, processing, and response. This approach not only improves monitoring flexibility and accuracy but also reduces system complexity and cost, providing technical support for the safety management of nuclear power plants.

[0110] In step S201 of some embodiments, the processing control module controls the radiation detector to select the current detection branch between the low-dose detection branch and the high-dose detection branch.

[0111] It should be noted that in the radiation signal monitoring device of a nuclear power plant, the processing and control module is the core component responsible for intelligently selecting the working branch of the radiation detector. Based on the dose rate level of the current radiation environment, the processing and control module automatically controls the radiation detector to switch between low-dose and high-dose detection branches to adapt to different radiation monitoring needs. Specifically, the low-dose detection branch is used for radiation detection in the low-dose radiation range, while the high-dose detection branch is used for radiation detection in the high-dose radiation range. The low-dose detection branch is equipped with a specially designed low-dose radiation sensitive element and a low-dose signal conditioning module, which can provide high sensitivity and high accuracy detection capabilities in the low-dose radiation range, suitable for routine monitoring or environments with low radiation levels. Conversely, the high-dose detection branch is equipped with a high-dose sensitive element and a high-dose signal conditioning module capable of withstanding and accurately measuring high-dose radiation, suitable for situations where radiation leakage or other situations leading to a sharp increase in radiation levels may occur.

[0112] Through this intelligent switching mechanism, the processing control module of this embodiment ensures that the radiation signal monitoring device can provide accurate monitoring results under different radiation levels, while avoiding measurement errors or equipment damage caused by radiation levels exceeding the range of the radiation detector. This design not only improves the adaptability and reliability of the radiation signal monitoring device but also reduces the need for multiple different types of radiation detectors, thereby reducing cost and complexity. Furthermore, automatic switching of detection branches improves monitoring efficiency because operators do not need to manually adjust equipment settings; the system can automatically adapt to environmental changes, ensuring continuous and accurate radiation monitoring. This intelligent monitoring method is crucial for ensuring the safe operation of nuclear power plants and timely response to potential radiation risks.

[0113] Referring to Figure 3, according to some embodiments of this application, the radiation detection time slot corresponding to the current radiation detection information is the current detection time slot. Step S201, selecting the current detection branch from the low-dose detection branch and the high-dose detection branch, may include:

[0114] Step S301: Obtain historical radiation detection information corresponding to the historical detection time slots; wherein, the historical radiation detection information refers to the radiation detection time slots before the current detection time slot;

[0115] Step S302: Compare the low-dose radiation range and the high-dose radiation range with historical radiation detection information to obtain the radiation range comparison results;

[0116] Step S303: Based on the radiation interval comparison results, select the current detection branch from the low-dose detection branch and the high-dose detection branch.

[0117] In some embodiments of this application, the process of selecting the current detection branch involves analyzing historical radiation detection information and assessing the current radiation level. This process ensures that the nuclear power plant's radiation signal monitoring device can intelligently select the most suitable detection branch for radiation detection based on changes in the radiation environment.

[0118] In some embodiments, step S301 involves acquiring historical radiation detection information corresponding to historical detection time slots. This historical radiation detection information contains radiation level data prior to the current detection time slot, providing important reference for assessing the current radiation environment. By analyzing this historical radiation detection information, embodiments of this application can understand the trend of radiation level changes and whether any abnormal radiation events exist.

[0119] In step S302 of some embodiments, the low-dose radiation range and the high-dose radiation range are compared with historical radiation detection information. The purpose of this comparison process is to determine the relationship between the current radiation level and the preset radiation range. If the historical radiation detection information shows that the radiation level has always been low, the embodiments of this application may tend to select the low-dose detection branch as the current detection branch, because the low-dose detection branch can provide higher sensitivity and accuracy at this time. Conversely, if the historical radiation detection information shows that the radiation level has reached or exceeded the high-dose radiation range, the embodiments of this application may select the high-dose detection branch to ensure that accurate measurement results can still be obtained under high radiation levels.

[0120] In step S303 of some embodiments, based on the radiation interval comparison results, this embodiment selects the current detection branch from the low-dose detection branch and the high-dose detection branch. This selection is based on the analysis of historical radiation detection information and the assessment of the current radiation environment, ensuring that the nuclear power plant radiation signal monitoring device can provide optimal monitoring performance under different radiation levels. In this way, the nuclear power plant radiation signal monitoring device can flexibly adapt to changes in the radiation environment, providing accurate and reliable monitoring data under both low-dose and high-dose radiation conditions.

[0121] Referring to Figure 4, according to some embodiments of this application, step S303, selecting the current detection branch from the low-dose detection branch and the high-dose detection branch based on the radiation interval comparison results, may include:

[0122] Step S401: If the comparison results of the radiation intervals show that the historical radiation detection information does not meet the preset detection range transition conditions, select the low-dose detection branch as the current detection branch.

[0123] Step S402: If the comparison results of the radiation interval reflect that the historical radiation detection information meets the detection range transition conditions, select the high-dose detection branch as the current detection branch.

[0124] In some embodiments of this application, the process of selecting the current detection branch is an intelligent decision based on radiation range comparison results. This process ensures that the nuclear power plant radiation signal monitoring device can automatically select the most suitable detection branch for radiation detection based on historical radiation detection information and preset detection range transition conditions.

[0125] In step S401 of some embodiments, if the radiation range comparison result shows that the historical radiation detection information does not meet the preset detection range transition conditions, it means that the current radiation level has not reached the point where it is necessary to switch to the high-dose detection branch. In this case, embodiments of this application will select the low-dose detection branch as the current detection branch. The low-dose detection branch is equipped with specially designed low-dose radiation sensitive elements and signal conditioning modules, which can provide high sensitivity and high accuracy detection capabilities in the low-dose radiation range, and are suitable for daily monitoring or environments with low radiation levels. Selecting the low-dose detection branch can ensure accurate monitoring in normal operation or low-radiation level environments, while avoiding unnecessary resource consumption.

[0126] In step S402 of some embodiments, if the radiation interval comparison results show that the historical radiation detection information meets the detection range transition condition, this indicates that the radiation level has reached or exceeded a preset threshold, requiring a higher detection capability. In this case, embodiments of this application select a high-dose detection branch as the current detection branch. The high-dose detection branch is equipped with sensitive elements and conditioning modules capable of withstanding and accurately measuring high-dose radiation, and is suitable for situations where radiation leakage or other situations leading to a sharp increase in radiation levels may occur.

This conversion process is a key step in signal conditioning, ensuring that the weak sensing signal received from the low-dose radiation-sensitive element can be effectively processed and converted for subsequent amplification and analysis.

[0149] It should be noted that pulse conditioning circuits can convert continuous radiation-induced signals into a series of discrete pulse signals. These discrete pulse signals can more accurately represent radiation events because the radiation-induced signals caused by radiation events have definite time intervals and amplitudes. Converting low-dose radiation-induced signals into low-dose radiation pulse signals makes the signals easier to digitize and quantize. Pulse conditioning circuits may include a series of electronic components, such as amplifiers, filters, limiters, and shapers, which work together to enhance the characteristics of the signal and prepare it for further processing.

[0172] An electrometer is a highly sensitive measuring device capable of directly measuring changes in electric charge, suitable for signal processing in high-dose-rate environments. The advantage of an electrometer lies in its very high measurement accuracy, especially at high signal strengths. However, electrometers can be sensitive to ambient noise; therefore, in some cases, further pulse conditioning may be necessary to ensure signal quality and measurement accuracy. An electrometer can convert high-dose radiation-induced signals into high-dose radiation pulse signals, which can then be further processed to generate current radiation detection information.

[0173] By utilizing pulse conditioning circuitry or an electrometer, the high-dose signal conditioning module can convert the raw high-dose radiation sensing signal into a clear and accurate high-dose radiation pulse signal. These high-dose radiation pulse signals can then be further amplified and shaped to ultimately generate current radiation detection information, providing accurate data to the processing and control module. This enables the entire nuclear power plant radiation signal monitoring device to effectively assess radiation levels and respond promptly to any anomalies.

[0178] In some embodiments, step S203 involves transmitting the current radiation detection information to the processing control module via the radiation detector.

[0179] In the nuclear power plant radiation signal monitoring method of this application embodiment, step S203 involves the process of the radiation detector transmitting the current radiation detection information to the processing and control module. This step is a key link in the information flow in the monitoring device, ensuring that the detected data can be transmitted to the processing and control module in a timely and accurate manner for further analysis and processing.

[0180] After a radiation detector probes within a target radiation monitoring area, it collects data on the radiation level of that area. This data can include information such as the type, intensity, and energy distribution of radiation, which is crucial for assessing the radiation environment and taking appropriate safety measures. In some embodiments, the radiation detector can perform preliminary processing on the raw acquired detection signal through an internal signal conditioning module, converting it into a format suitable for transmission. This may include amplifying weak signals, filtering noise, and converting signal formats to ensure data quality and reliable transmission.

[0181] It should be understood that once the current radiation detection information is conditioned to a suitable state, the radiation detector can transmit this information to the processing and control module.

Based on these analysis results, the processing and control module can generate monitoring indication signals, providing a basis for the monitoring indication module to execute monitoring response operations. This may include triggering audible and visual alarms, recording data, adjusting detection parameters, or notifying operators.

[0182] Referring to Figure 9, according to some embodiments of this application, the nuclear power plant radiation signal monitoring device further includes an analog-to-digital conversion module, which is disposed in the integrated module. Step S203, which transmits the current radiation detection information to the processing and control module through the radiation detector, may include:

[0183] Step S901: The current radiation detection information is transmitted to the analog-to-digital conversion module through the radiation detector to convert the current radiation detection information from an analog signal to a digital signal;

[0185] In some embodiments of this application, the nuclear power plant radiation signal monitoring device further includes an analog-to-digital conversion module, which is integrated into an integrated module and is responsible for converting the analog signals collected by the radiation detector into digital signals. This conversion process is crucial for subsequent data processing and analysis, as it enables the signals to be efficiently processed and analyzed by modern electronic systems and computer programs.

[0186] In step S901 of some embodiments, the radiation detector transmits the collected current radiation detection information to the analog-to-digital conversion module. This information initially exists in the form of analog signals, reflecting continuous changes in radiation levels. The role of the analog-to-digital conversion module is to convert these analog signals into digital signals. This process typically involves sampling, quantizing, and encoding the analog signals. Sampling is the process of measuring signals at fixed time intervals, quantization is the process of mapping continuous signal amplitudes to the nearest discrete values, and encoding is the process of converting these discrete values ​​into digital form.

[0189] In summary, the information transmission process in step S203 is fundamental to ensuring the effective operation of the monitoring device. It enables the data collected by the radiation detector to be processed in a timely manner and used to ensure the safe operation of the nuclear power plant. In this way, the nuclear power plant radiation signal monitoring device of this application can achieve continuous monitoring of radiation levels and respond promptly to any abnormalities, thereby protecting personnel and the environment from radiation hazards.

[0190] In step S204 of some embodiments, a monitoring indication signal is generated in the processing control module based on the current radiation detection information;

[0191] In the nuclear power plant radiation signal monitoring method of this application, step S204 is a key step, which involves how the processing control module generates a monitoring indication signal based on the current radiation detection information received from the radiation detector.

[0192] It should be noted that after receiving the radiation detection information transmitted by the radiation detector, the processing and control module can use built-in algorithms and preset thresholds to analyze the radiation detection information, and realize statistical analysis, trend prediction, and anomaly detection of the radiation level of the target radiation monitoring area, so as to assess the current state and potential risks of the radiation environment.

[0193] In some embodiments, the preset threshold can be set based on safety standards and operating procedures to determine whether the radiation level exceeds the normal range. If the analysis results show that the radiation level is within the normal range, the processing control module can generate a monitoring indication signal indicating that the radiation environment is safe and no special measures are required. This monitoring indication signal can be a simple status indication, such as a constantly lit green light indicating normal operation. However, if the radiation level exceeds the preset threshold, the processing control module can generate a monitoring indication signal indicating a potential risk or emergency. This monitoring indication signal may include triggering an audible and visual alarm to immediately alert operators to potential hazards; initiating a data logging program for detailed analysis of the radiation event; or sending a notification to the control center requesting further guidance or support.

[0194] Furthermore, the monitoring indication signal may also include further instructions to the radiation detector, such as switching the detection branch to adapt to different radiation levels, or adjusting the detection parameters to improve measurement accuracy. These automated response measures help ensure that the nuclear power plant radiation signal monitoring device of this application embodiment can provide accurate and reliable monitoring data in various radiation environments and take appropriate safety measures in a timely manner.

[0195] In summary, the processing and control module in step S204 generates monitoring indication signals through intelligent analysis and judgment, providing an efficient and automated response mechanism for radiation monitoring in nuclear power plants. This not only improves the response speed and accuracy of radiation signal monitoring devices in nuclear power plants but also enhances the plant's ability to respond to radiation events, thereby better protecting the safety of personnel and the environment.

[0198] In some embodiments of this application, the design of the nuclear power plant radiation signal monitoring device includes a communication module integrated into an integrated module. This module is responsible for enabling data communication between the monitoring device and the nuclear power plant's distributed control system (DCS). This communication function is crucial for ensuring that monitoring data can be transmitted to the control system in a timely manner and triggering corresponding abnormal monitoring operations.

[0199] In step S204, the processing control module generates monitoring indication signals based on the current radiation detection information. These signals reflect the real-time status of the radiation level, including any possible anomalies or emergencies. Once the monitoring indication signals are generated, the communication module can intervene to perform its data transmission duties.

[0200] The monitoring indication signals are transmitted to the nuclear power plant's distributed control system (DCS) via the communication module. It is important to emphasize that the DCS is a centralized system for monitoring and controlling the entire nuclear power plant's operation. It receives signals from the plant's radiation monitoring devices and executes anomaly detection operations according to preset logic and safety protocols. These operations may include triggering alarms, recording events, adjusting process parameters, activating safety systems, or notifying operators.

[0201] In this way, nuclear power plant radiation monitoring devices can be tightly integrated with the DCS (Distributed Control System) to form a collaborative system. This integration not only improves the efficiency of monitoring data utilization but also enhances the nuclear power plant's ability to respond to potential radiation risks. Through automated anomaly monitoring operations, nuclear power plants can take timely measures to prevent radiation accidents or mitigate their impact, thereby protecting personnel safety and environmental health.

[0202] In some embodiments, step S205 involves the monitoring indication module receiving a monitoring indication signal from the processing control module and performing a monitoring response operation based on the monitoring indication signal.

[0203] In the nuclear power plant radiation signal monitoring method of this application, step S205 describes the role of the monitoring indication module in the nuclear power plant radiation signal monitoring device, namely, receiving monitoring indication signals from the processing and control module and executing corresponding monitoring response operations based on these signals. This step is the final link in the entire monitoring process, ensuring that monitoring data can be transformed into actual response measures to guarantee the safe operation of the nuclear power plant.

[0204] It should be noted that the monitoring indication module is the execution part of the radiation signal monitoring device in a nuclear power plant. It is responsible for taking action based on the monitoring indication signals generated by the processing control module, that is, executing monitoring response operations. Executing monitoring response operations may include, but are not limited to, triggering audible and visual alarm systems to warn on-site personnel of abnormally high radiation levels; initiating emergency procedures, such as closing access to specific areas or activating radiation protection facilities; and recording and reporting detailed information about radiation events for subsequent analysis and decision-making.

[0205] When the monitoring indication module receives a monitoring indication signal, it will execute the corresponding monitoring response operation. For example, if the signal indicates that the radiation level exceeds the safety threshold, the monitoring indication module may trigger a red alarm light and siren, and simultaneously send an emergency notification to the control center via the communication system. Furthermore, the monitoring indication module can also control other safety systems, such as automatically shutting down radiation sources or activating radiation shielding facilities.

[0206] In summary, the monitoring indication module in step S205 is an indispensable component of the nuclear power plant radiation signal monitoring device. By performing monitoring response operations, it ensures the practical application of the nuclear power plant radiation signal monitoring method of this application and the safety of the nuclear power plant. In this way, the nuclear power plant radiation signal monitoring device and method of this application can not only provide accurate radiation monitoring data but also take swift action when necessary to protect personnel and equipment from radiation hazards.

[0208] Step S1001: In the power management module, the input voltage is converted into various module operating voltages;

[0209] Step S1002: Based on the integrated module, the operating voltage of each module is allocated to the radiation detector, the processing control module, and the monitoring indication module.

[0210] In some embodiments of this application, the design of the nuclear power plant radiation signal monitoring device includes a power management module. This module acts as a bridge between the power module and the integrated module, responsible for converting the input voltage into the operating voltage required by each module within the device. The power management module is a critical component ensuring the stable operation of the entire monitoring device; it needs to provide accurate and stable power to meet the power demands of different modules.

[0211] In step S1001 of some embodiments, the power management module first receives an input voltage from the power module, which may be a standard voltage from the internal power system of the nuclear power plant. Then, the power management module converts this input voltage into various operating voltages via internal voltage conversion circuitry. These operating voltages may include, but are not limited to, specific voltages required to power critical components such as radiation detectors, processing control modules, and monitoring indication modules.

[0212] In step S1002 of some embodiments, the converted multiple operating voltages are then received by the integration module, which is responsible for accurately allocating the required operating voltage for each module to the corresponding components. This allocation is based on the specific requirements and design parameters of each module, ensuring that each module operates in its optimal state. For example, a radiation detector may require a stable low voltage to ensure accurate measurements of its sensitive elements, while a processing control module may require a slightly higher voltage to support its complex data processing tasks.

[0213] Through the embodiments of this application shown in steps S1001 to S1002, the collaborative operation of the power management module and the integration module enables the nuclear power plant radiation signal monitoring device to ensure that all components receive adequate power, thereby achieving efficient and reliable radiation monitoring.
