[0073] Radioactive radiation detection devices are used to assess the radioactivity level at different locations in the power plant, to protect personnel from the hazards of abnormal situations, and to monitor the status after an accident. In some work areas, the dose rate is usually low, but it may suddenly increase by an order of magnitude, affecting the residence of the staff. The dose rate of the radiation signal needs to be continuously measured, and an audible and visual alarm signal is given when the radioactivity level or dose rate exceeds the preset threshold.
[0074] First, the main problem faced by radioactive radiation detection devices in related technologies (such as common nuclear power plant gamma radiation area monitoring devices) is the limitation of signal and information transmission methods. These radioactive radiation detection devices usually include 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 some probes that can interact with the received radiation.
[0076] LPDU refers to the local processing display unit, which is an important component of the radiation signal monitoring device of a nuclear power plant. The main function of LPDU is to receive signals from radiation detectors, obtain digital or analog information after data processing, and send this information to the upper structure for further analysis and operation. LPDU usually includes functions such as data processing, display, and alarm, which can realize local monitoring and preliminary processing of detection signals. The local processing display unit can be responsible for receiving and processing detection signals, obtaining measurement values, and issuing sound and light alarm signals when the preset threshold is exceeded or a fault occurs.
[0077] The electrical connection box is connected to the LPDU and connected to the distributed control system of the nuclear power plant through power cables and communication cables, so that the distributed control system can centrally monitor the monitoring channels. Among them, the distributed control system (DCS), also known as the distributed control system, is a multi-level computer system that integrates computer, communication, display and control technologies. Its core concept is decentralized control and centralized management.
[0078] However, there are several major technical problems in implementing these functions:
[0079] Firstly, the radioactive radiation detection device in the related art cannot be directly matched with the system based on bus transmission technology, which limits the compatibility and scalability of the monitoring device.
[0080] Secondly, the measurement range of existing radiation detectors is limited. In order to meet 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 configuration of existing radiation detectors is relatively complex and has many interfaces, which places certain requirements on the on-site layout space and also brings a large workload to the installation and operation and maintenance personnel.
[0082] In general, radioactive radiation detection devices in related technologies face problems such as signal transmission mismatch, limited measurement range, and complex configuration when implementing monitoring tasks in the radioactive environment of nuclear power plants. These problems not only affect the performance and reliability of the monitoring device, but also increase the cost and difficulty of operation and maintenance.
[0083] The present application aims to solve at least one of the technical problems existing in the prior art. To this end, the present application proposes a nuclear power plant radiation signal monitoring device and method, electronic equipment, and storage medium, which can effectively collect a wide range of radiation signals without significantly increasing complexity and cost.
[0084] Further explanation is given below based on the accompanying drawings.
[0085] Reference Figure 1A According to an embodiment of the present application, a nuclear power plant radiation signal monitoring device may include:
[0086] A power module, used to provide input voltage to a radiation signal monitoring device of a nuclear power plant;
[0087] It should be noted that the power module is the basis of the entire monitoring device. It is responsible for providing a stable input voltage to the nuclear power plant radiation signal monitoring device. The design of the power module needs to take into account the possible electromagnetic interference and power supply fluctuations 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 three types of power sources: a linear regulated power supply, an external 24V input power supply, and a rechargeable lithium battery with an internal 24V output. 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] A radiation detector, comprising a low-dose detection branch and a high-dose detection branch arranged in a target radiation monitoring field, wherein the low-dose detection branch is provided with a low-dose radiation sensitive element and a low-dose signal conditioning module, and the high-dose detection branch is provided with a high-dose radiation sensitive element and a high-dose signal conditioning module; wherein the low-dose detection branch is used for radiation detection in a low-dose radiation detection interval, and the high-dose detection branch is used for radiation detection in a high-dose radiation detection interval;
[0090] It should be noted that the radiation detector is the core of the monitoring device, which includes a low-dose detection branch and a high-dose detection branch set up in the target radiation monitoring field. The low-dose detection branch is equipped with low-dose radiation sensitive elements and low-dose signal conditioning modules, which are specially used for radiation detection in the low-dose radiation range. These low-dose radiation sensitive elements and low-dose signal conditioning modules can detect and process weak radiation signals to ensure accurate monitoring in normal operation or low-radiation level environments. The high-dose detection branch is equipped with high-dose radiation sensitive elements and high-dose signal conditioning modules for radiation detection in the high-dose radiation range. These high-dose radiation sensitive elements and high-dose signal conditioning modules are designed to provide reliable monitoring data when radiation levels rise sharply, such as in nuclear accidents or leaks.
[0091] A processing control module, used to control the radiation detector to detect current radiation detection information using a low-dose detection branch or a high-dose detection branch, and to generate a monitoring indication signal according to 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 radiation signal monitoring device. It is responsible for controlling the switching of the radiation detector between the low-dose detection branch and the high-dose detection branch to meet the current radiation detection needs. The processing and control module can generate monitoring indication signals based on the received radiation detection information. These monitoring indication signals reflect the current radiation level and possible threats.
[0093] A monitoring indication module, used to receive a monitoring indication signal from the processing control module and perform a monitoring response operation according to the monitoring indication signal;
[0094] It should be noted that the monitoring and indication module receives monitoring and indication signals from the processing and control module and performs monitoring and response operations based on these signals. This may include triggering alarms, recording data, adjusting detection parameters, or notifying operators. The design of the monitoring and indication module needs to ensure rapid response and accurate execution so that appropriate measures can be taken in a timely manner.
[0095] An integrated module is used to integrate a power module, a radiation detector, a processing control module and a monitoring indication module.
[0096] It is worth noting that the integrated module integrates the power module, radiation detector, processing control module and monitoring indicator module into a compact and efficient nuclear power plant radiation signal monitoring device. The design of the integrated module takes into account 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 Another example diagram of a nuclear power plant radiation signal monitoring device is shown. The nuclear power plant radiation signal monitoring device can be composed of multiple key modules that work together to monitor and process radiation signals. The integrated module of the embodiment of the present application integrates key components such as the power management module, the processing control module, the analog-to-digital conversion module, and the communication module into a whole to facilitate the management and coordination of the entire monitoring process.
[0098] The power module is responsible for providing a stable power supply for the entire nuclear power plant radiation signal monitoring device, while the power management module is responsible for converting this power into the specific voltage required by each module within the embodiment of the present application, ensuring that each component can operate at its optimal state. The processing control module is the brain of the embodiment of the present application. It receives data from the radiation detector, analyzes and processes it, generates monitoring indication signals, and controls the operation of other modules.
[0099] The analog-to-digital conversion module (AD / DA) plays the role of a bridge in the embodiment of the present application. It converts analog signals into digital signals for analysis by the processing control module, and can also convert digital signals back into analog signals for controlling output or driving other devices. The communication module is responsible for realizing data exchange between the monitoring device and the external embodiment of the present application. It may include a wired or wireless communication interface to ensure that the monitoring data can be transmitted to the remote monitoring embodiment of the present application or receive instructions from the control center in a timely manner.
[0100] The radiation detector is the part that directly contacts the radiation source. It includes two detection branches, low-dose and high-dose, each of which is equipped with a corresponding signal conditioning module and sensitive element. The low-dose signal conditioning module and the high-dose signal conditioning module are responsible for the preliminary processing of the low-dose and high-dose radiation sensing signals, respectively, to facilitate the subsequent analog-to-digital conversion and analysis. The design of these conditioning modules ensures that the embodiments of the present application can provide accurate monitoring results under different radiation levels.
[0101] The monitoring indication module performs corresponding operations according to the monitoring indication signal generated by the processing control module, such as triggering an alarm, recording data, or adjusting detection parameters, to ensure timely response when the radiation level exceeds the preset threshold. The communication interface is a physical interface for the monitoring device to exchange data with other embodiments of the present application. It supports multiple communication protocols to adapt to different application scenarios.
[0102] In general, the nuclear power plant radiation signal monitoring device of the embodiment of the present application realizes comprehensive monitoring and processing of radiation signals by integrating multiple functional modules. 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] Reference Figure 2 According to the nuclear power plant radiation signal monitoring method of the embodiment of the present application, it is applied to the nuclear power plant radiation signal monitoring device of the embodiment of the present application, wherein the nuclear power plant radiation signal monitoring method may include:
[0104] Step S201, controlling the radiation detector to select a current detection branch from a low-dose detection branch and a high-dose detection branch through a processing control module; wherein the low-dose detection branch is used to perform radiation detection in a low-dose radiation detection interval, and the high-dose detection branch is used to perform radiation detection in a high-dose radiation interval;
[0105] Step S202, controlling the current detection branch to perform radiation detection in the target radiation monitoring field through the radiation detector to obtain corresponding current radiation detection information;
[0106] Step S203, transmitting the current radiation detection information to the processing control module through the radiation detector;
[0107] Step S204, generating a monitoring indication signal in the processing control module according to the current radiation detection information;
[0108] Step S205: the monitoring instruction module receives the monitoring instruction signal from the processing control module, and performs a monitoring response operation according to the monitoring instruction signal.
[0109] In view of the problem that radioactive radiation detection devices in related technologies have limited measurement range under different monitoring requirements, the nuclear power plant radiation signal monitoring method of the embodiment of the present application realizes the monitoring of a wide range of radiation signals through intelligent detection and processing control without significantly increasing the complexity and cost of the system. The nuclear power plant radiation signal monitoring method of the embodiment of the present application 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 method not only improves the flexibility and accuracy of monitoring, but also reduces the complexity and cost of the system, 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 a current detection branch between a low-dose detection branch and a 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. The processing and control module automatically controls the radiation detector to switch between the low-dose detection branch and the high-dose detection branch according to the dose rate level of the current radiation environment to adapt to different radiation monitoring needs. Among them, the low-dose detection branch is used for radiation detection in the low-dose radiation detection interval, and the high-dose detection branch is used for radiation detection in the high-dose radiation interval. The low-dose detection branch is equipped with specially designed low-dose radiation sensitive elements and low-dose signal conditioning modules. The low-dose radiation sensitive elements and low-dose signal conditioning modules can provide high-sensitivity and high-precision detection capabilities in the low-dose radiation interval, which are suitable for daily monitoring or environments with low radiation levels. On the contrary, the high-dose detection branch is equipped with high-dose sensitive elements and high-dose signal conditioning modules that can withstand and accurately measure high-dose radiation, and is suitable for situations where radiation leakage may occur or other situations that cause a sharp increase in radiation levels.
[0112] Through this intelligent switching mechanism, the processing and control module of the embodiment of the present application ensures that the radiation signal monitoring device can provide accurate monitoring results at 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 a variety of different types of radiation detectors, thereby reducing costs and complexity. In addition, the automatic switching of detection branches also improves monitoring efficiency, because the operator does not need to manually adjust the equipment settings, and the system can automatically adapt to environmental changes to ensure continuous and accurate radiation monitoring. This intelligent monitoring method is crucial to ensuring the safe operation of nuclear power plants and timely responding to potential radiation risks.
[0113] Reference Figure 3 According to some embodiments of the present application, the radiation detection time slot corresponding to the current radiation detection information is the current detection time slot, and step S201 selects the current detection branch from the low-dose detection branch and the high-dose detection branch, which may include:
[0114] Step S301, obtaining historical radiation detection information corresponding to a historical detection time slot; wherein the historical radiation detection information is a radiation detection time slot before a current detection time slot;
[0115] Step S302, comparing the low-dose radiation interval and the high-dose radiation interval with the historical radiation detection information to obtain a radiation interval comparison result;
[0116] Step S303: selecting a current detection branch from the low-dose detection branch and the high-dose detection branch according to the radiation interval comparison result.
[0117] In some embodiments of the present application, the process of selecting the current detection branch involves analyzing historical radiation detection information and evaluating the current radiation level. This process ensures that the nuclear power plant radiation signal monitoring device can intelligently select the most appropriate detection branch for radiation detection according to changes in the radiation environment.
[0118] In step S301 of some embodiments, historical radiation detection information corresponding to the historical detection time slot is obtained. These historical radiation detection information contain radiation level data before the current detection time slot, which provides an important reference for evaluating the current radiation environment. By analyzing these historical radiation detection information, the embodiments of the present application can understand the changing trend of the radiation level and whether there are any abnormal radiation events.
[0119] In step S302 of some embodiments, the low-dose radiation interval and the high-dose radiation interval are compared with the historical radiation detection information. The purpose of this comparison process is to determine the relationship between the current radiation level and the preset radiation interval. If the historical radiation detection information shows that the radiation level has always been low, the embodiment of the present 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. On the contrary, if the historical radiation detection information shows that the radiation level has reached or exceeded the high-dose radiation interval, the embodiment of the present application may select the high-dose detection branch to ensure that accurate measurement results can still be obtained at high radiation levels.
[0120] In step S303 of some embodiments, according to the radiation interval comparison result, the embodiment of the present application 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 evaluation of the current radiation environment, ensuring that the nuclear power plant radiation signal monitoring device can provide the best 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 and provide accurate and reliable monitoring data regardless of low-dose or high-dose radiation conditions.
[0121] Reference Figure 4 According to some embodiments of the present application, step S303 selects a current detection branch from a low-dose detection branch and a high-dose detection branch according to the radiation interval comparison result, which may include:
[0122] Step S401, when the radiation interval comparison result reflects that the historical radiation detection information does not meet the preset detection range transition condition, a low-dose detection branch is selected as the current detection branch;
[0123] Step S402: When the comparison result in the radiation interval reflects that the historical radiation detection information meets the detection range transition condition, a high-dose detection branch is selected as the current detection branch.
[0124] In some embodiments of the present application, the process of selecting the current detection branch is an intelligent decision based on the radiation interval comparison result. This process ensures that the nuclear power plant radiation signal monitoring device can automatically select the most appropriate 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 interval comparison result shows that the historical radiation detection information does not meet the preset detection range transition condition, this means that the current radiation level has not reached the level that requires switching to the high-dose detection branch. In this case, the embodiment of the present 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-precision detection capabilities within the low-dose radiation interval, and are suitable for daily monitoring or environments with low radiation levels. Selecting a low-dose detection branch can ensure accurate monitoring during normal operation or in a low-radiation level environment while avoiding unnecessary resource consumption.
[0126] In step S402 of some embodiments, if the radiation interval comparison result shows that the historical radiation detection information meets the detection range transition condition, this indicates that the radiation level has reached or exceeded the preset threshold and requires a higher intensity detection capability. In this case, the embodiment of the present application will select a high-dose detection branch as the current detection branch. The high-dose detection branch is equipped with sensitive elements and conditioning modules that can withstand and accurately measure high-dose radiation, and is suitable for situations where radiation leakage may occur or other situations that cause a sharp increase in radiation levels. Selecting a high-dose detection branch can ensure that accurate measurement results can still be obtained at high radiation levels, and potential radiation risks can be responded to in a timely manner.
[0127] Through the method shown in step S401 to step S402, the nuclear power plant radiation signal monitoring device can intelligently select the most appropriate detection branch according to the actual changes in the radiation environment, thereby realizing effective monitoring of different radiation levels. This design not only improves the flexibility and accuracy of monitoring, but also reduces the cost and complexity of the embodiment of the present application, and provides strong technical support for the safety management of nuclear power plants. By automatically adapting to changes in the radiation environment, the nuclear power plant radiation signal monitoring device can operate more efficiently and ensure that reliable monitoring data can be provided at various radiation levels.
[0128] It can be seen that the current detection branch selection process reflects the intelligent and automated characteristics of the nuclear power plant radiation signal monitoring device. It realizes the intelligent selection of the current detection branch by analyzing historical radiation detection information and evaluating the current radiation level, thereby improving the adaptability and monitoring efficiency of the nuclear power plant radiation signal monitoring device. This design not only improves the accuracy of radiation monitoring, but also helps to enhance the nuclear power plant's ability to respond to radiation events, providing a strong guarantee for the safe operation of the nuclear power plant.
[0129] In step S202 of some embodiments, the radiation detector controls the current detection branch to perform radiation detection in the target radiation monitoring field to obtain corresponding current radiation detection information;
[0130] In the nuclear power plant radiation signal monitoring method of the embodiment of the present application, step S202 describes the process of controlling 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. This step ensures that the nuclear power plant radiation signal monitoring device can select a suitable detection branch according to the current radiation environment, thereby achieving accurate measurement of the radiation level.
[0131] In the low-dose detection branch, low-dose radiation sensitive elements and low-dose signal conditioning modules work together to detect radiation in the low-dose radiation range. These elements and modules are specially designed to detect weak radiation signals, and they can provide high sensitivity and high-precision detection capabilities in normal operation or low-radiation level environments. When the radiation level rises and exceeds the measurement range of the low-dose detection branch, the processing control module will intelligently switch to the high-dose detection branch.
[0132] The high-dose detection branch is equipped with high-dose radiation sensitive components and high-dose signal conditioning modules, which can withstand and accurately measure high-dose radiation. They are suitable for situations where radiation leakage or other situations that cause a sharp increase in radiation levels may occur, ensuring that reliable monitoring data can still be provided in these emergency situations.
[0133] Through this design, the radiation detector can automatically select the most appropriate detection branch under different radiation levels, thereby realizing effective monitoring of a wide range of radiation signals, which not only improves the flexibility and accuracy of monitoring, but also reduces cost and complexity.
[0134] Reference Figure 5 According to some embodiments of the present application, the current detection branch is a low-dose detection branch, and step S202 controls the current detection branch to perform radiation detection in the target radiation monitoring field through the radiation detector to obtain corresponding current radiation detection information, which may include:

[0136] Step S502: performing a low-dose signal conditioning operation on the low-dose radiation sensing signal by a low-dose signal conditioning module to obtain current radiation detection information.
[0137] In some embodiments of the present application, when the current detection branch is a low-dose detection branch, the radiation detector will use this detection branch to perform radiation detection in the target radiation monitoring field to obtain accurate current radiation detection information.
[0138] In step S501 of some embodiments, low-dose radiation sensitive elements are used to perform radiation sensing in the target radiation monitoring field. These sensitive elements are specially designed to detect low-level radiation. They can sense weak radiation changes in the environment and convert them into low-dose radiation sensing signals. Although these signals are weak, they contain important information about the radiation level and are the basis for subsequent analysis and processing.
[0139] In step S502 of some embodiments, the low-dose signal conditioning module further processes these low-dose radiation sensing signals. The signal conditioning operation may include amplifying the signal for detection, filtering to remove noise, and converting the signal format to ensure the quality and reliability of the signal. The conditioned signal is converted into current radiation detection information, which can accurately reflect the radiation level of the target radiation monitoring field.
[0140] Reference Figure 6 According to some embodiments of the present application, step S502 performs a low-dose signal conditioning operation on the low-dose radiation sensing signal to obtain current radiation detection information, which may include:
[0141] Step S601, converting the low-dose radiation sensing signal into a low-dose radiation pulse signal;
[0142] Step S602, performing signal amplification processing on the low-dose pulse signal to obtain a low-dose radiation amplified signal;
[0143] Step S603, performing a shaping operation on the low-dose radiation amplified signal to obtain current radiation detection information.
[0144] In some embodiments of the present application, performing low-dose signal conditioning on low-dose radiation sensing signals is a key step in obtaining accurate radiation detection information. This process includes three main steps, each of which is intended to improve the quality of low-dose radiation sensing signals and ensure that the current radiation detection information obtained is both accurate and reliable.
[0145] In step S601 of some embodiments, the low-dose radiation sensing signal is converted into a low-dose radiation pulse signal. This conversion process utilizes the characteristics of the radiation sensitive element to convert the continuous radiation sensing signal into a series of pulse signals. Such pulse signals are easier to be processed by subsequent electronic circuits because they have clear time intervals and amplitudes and can more accurately represent radiation events.
[0146] According to some embodiments of the present application, the low-dose signal conditioning module includes a pulse conditioning circuit, and step S601 converts the low-dose radiation sensing signal into a low-dose radiation pulse signal, which may include:
[0147] A pulse conditioning circuit is used to convert the low-dose radiation sensing signal into a low-dose radiation pulse signal.
[0148] In some embodiments of the present application, the design core of the low-dose signal conditioning module lies in the pulse conditioning circuit it contains, which is responsible for converting the low-dose radiation sensing signal into a low-dose radiation pulse signal. This conversion process is a key step in signal conditioning, which ensures 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 the pulse conditioning circuit can convert the continuous radiation sensing signal into a series of discrete pulse signals. These discrete pulse signals can more accurately represent the radiation event, because the radiation sensing signal caused by the radiation event has a clear time interval and amplitude. After the low-dose radiation sensing signal is converted into a low-dose radiation pulse signal, the signal is easier to be digitized and quantized. The pulse conditioning circuit can include a series of electronic components, such as amplifiers, filters, limiters and shapers, which work together on the signal to enhance its characteristics and prepare it for the next step of processing.
[0150] In some more specific embodiments, first, an amplifier can be used to enhance the amplitude of the signal so that the originally weak radiation-induced signal reaches a level that can be further processed. Then, a filter is used to remove noise and interference in the signal to ensure the purity of the signal. Furthermore, a limiter is used to limit the amplitude of the signal to prevent the signal from being too large and distorted. Finally, a shaper is used to convert the signal into a pulse with a uniform shape and amplitude to facilitate subsequent analog-to-digital conversion and data analysis.
[0151] Therefore, through these functions of the pulse conditioning circuit, the low-dose signal conditioning module can convert the original low-dose radiation sensing signal into a clear and accurate low-dose radiation pulse signal. These low-dose radiation pulse signals can then be further amplified and shaped to ultimately generate current radiation detection information, providing accurate data for the processing control module, thereby enabling the nuclear power plant radiation signal monitoring method of the present application to more effectively assess radiation levels and respond to any abnormal conditions in a timely manner. This signal conditioning method ensures that in a low-dose radiation environment, the nuclear power plant radiation signal monitoring device can still provide high-quality monitoring data, providing important support for the safe operation of the nuclear power plant.
[0152] In step S602 of some embodiments, these low-dose pulse signals are amplified. Since the original low-dose radiation induced signals may be very weak, the amplification process is to enhance the amplitude of these signals to a level that can be further processed and analyzed. Signal amplification is a common step in signal conditioning, which helps to improve the signal-to-noise ratio of the signal, making the useful information in the signal more prominent.
[0153] In step S603 of some embodiments, a shaping operation is performed on the low-dose radiation amplified signal. The shaping operation includes processes such as limiting, differentiation, and integration, and the purpose is to convert the amplified pulse signal into a pulse with a uniform shape and amplitude for digitization and quantization processing. The shaped signal is more standardized, which is convenient for subsequent analog-to-digital conversion and data analysis.
[0154] Through the three steps of step S601 to step S603, the low-dose signal conditioning module can convert the original low-dose radiation sensing signal into clear and accurate current radiation detection information. This information can then be received and analyzed by the processing control module to evaluate the radiation level and generate corresponding monitoring indication signals. This signal conditioning method ensures that high-quality monitoring data can still be provided in a low-dose radiation environment, providing important support for the safe operation of nuclear power plants.
[0155] Through the two steps of step S501 to step S502, the low-dose detection branch can effectively detect and process low-dose radiation signals, and provide accurate data for the processing control module, so that the entire nuclear power plant radiation signal monitoring device can effectively monitor and evaluate the low-dose radiation environment. This design not only improves the sensitivity and accuracy of the nuclear power plant radiation signal monitoring device, but also ensures that the monitoring device can provide reliable monitoring results at low-dose radiation levels, providing support for the safety management of the nuclear power plant.

The signal conditioning operation may include amplifying the signal for detection, filtering to remove noise, and converting the signal format to ensure the quality and reliability of the signal. The conditioned signal is converted into current radiation detection information, which can accurately reflect the high radiation level of the target radiation monitoring field.

[0168] According to some embodiments of the present application, the high-dose signal conditioning module includes a pulse conditioning circuit or an electrometer, and step S801 converts the high-dose radiation sensing signal into a high-dose radiation pulse signal, which may include:
[0169] The high-dose radiation induction signal is converted into a high-dose radiation pulse signal using a pulse conditioning circuit or an electrometer.
[0170] In some embodiments of the present application, the high-dose signal conditioning module is intended to effectively convert the high-dose radiation sensing signal into a high-dose radiation pulse signal, in order to ensure the quality and reliability of the signal for subsequent analysis and processing. The high-dose signal conditioning module may include a pulse conditioning circuit or an electrometer, both of which have their own characteristics and advantages and are suitable for different application scenarios.
[0171] Pulse conditioning circuits are commonly used electronic circuits that are able to convert continuous radiation-induced signals into a series of discrete pulse signals. These pulse signals are easier to digitize and quantize because they have well-defined time intervals and amplitudes, which can more accurately represent radiation events. Pulse conditioning circuits may include a series of electronic components such as amplifiers, filters, limiters, and shapers, which work together to act on the signal to enhance its characteristics and prepare it for further processing. In this way, pulse conditioning circuits are able to convert high-dose radiation-induced signals into high-dose radiation pulse signals, providing the basis for subsequent signal amplification and shaping operations.
[0172] An electrometer is a highly sensitive measurement device that can directly measure changes in charge and is suitable for signal processing in high dose rate environments. The advantage of an electrometer is that it can provide very high measurement accuracy, especially when the signal strength is high. However, electrometers can be sensitive to environmental noise, so in some cases, it may still be necessary to further process the signal using pulse conditioning to ensure signal quality and measurement accuracy. An electrometer can convert high-dose radiation sensing signals into high-dose radiation pulse signals, which can then be further processed to generate current radiation detection information.
[0173] By utilizing a pulse conditioning circuit or an electrometer, the high-dose signal conditioning module can convert the original 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 for the processing and control module, so that the entire nuclear power plant radiation signal monitoring device can effectively assess the radiation level and respond to any abnormal situation in a timely manner. This signal conditioning method ensures that in a high-dose radiation environment, the nuclear power plant radiation signal monitoring device can still provide high-quality monitoring data, providing important support for the safe operation of the nuclear power plant. In this way, the nuclear power plant radiation signal monitoring device of the present application can achieve continuous monitoring of radiation levels and respond to any abnormal situation in a timely manner, thereby protecting personnel and the environment from radiation hazards.
[0174] In step S802 of some embodiments, these high-dose pulse signals are amplified. Since the original high-dose radiation induced signals may be very weak, the amplification process is to enhance the amplitude of these signals to a level that can be further processed and analyzed. Signal amplification is a common step in signal conditioning, which helps to improve the signal-to-noise ratio of the signal, making the useful information in the signal more prominent.
[0175] In step S803 of some embodiments, a shaping operation is performed on the high-dose radiation amplified signal. The shaping operation includes processes such as limiting, differentiation, and integration, and the purpose is to convert the amplified pulse signal into a pulse with a uniform shape and amplitude for digitization and quantization processing. The shaped signal is more standardized, which is convenient for subsequent analog-to-digital conversion and data analysis.
[0176] Through the three steps of step S801 to step S803, the high-dose signal conditioning module can convert the original high-dose radiation sensing signal into clear and accurate current radiation detection information. This information can then be received and analyzed by the processing control module to evaluate the radiation level and generate corresponding monitoring indication signals. This signal conditioning method ensures that the nuclear power plant radiation signal monitoring device can still provide high-quality monitoring data in a high-dose radiation environment, providing important support for the safe operation of the nuclear power plant. In this way, the nuclear power plant radiation signal monitoring device can achieve continuous monitoring of radiation levels and respond to any abnormal conditions in a timely manner, thereby protecting personnel and the environment from radiation hazards.
[0177] Through the two steps of step S701 to step S702, the high-dose detection branch can effectively detect and process high-dose radiation signals, and provide accurate data for the processing control module, so that the nuclear power plant radiation signal monitoring device can effectively monitor and evaluate the high-dose radiation environment. This design not only improves the sensitivity and accuracy of the nuclear power plant radiation signal monitoring device, but also ensures that the nuclear power plant radiation signal monitoring device can provide reliable monitoring results under high-dose radiation levels, and provide support for the safety management of the nuclear power plant. In this way, the nuclear power plant radiation signal monitoring device can realize continuous monitoring of radiation levels and respond to any abnormal situation in a timely manner, thereby protecting personnel and the environment from radiation hazards.
[0178] In step S203 of some embodiments, current radiation detection information is transmitted to a processing control module via the radiation detector;
[0179] In the nuclear power plant radiation signal monitoring method of the embodiment of the present application, step S203 involves the process of the radiation detector transmitting the current radiation detection information to the processing control module. This step is a key link in the information flow in the monitoring device, which ensures that the detected data can be timely and accurately transmitted to the processing control module for further analysis and processing.
[0180] After the radiation detector detects in the target radiation monitoring field, it will collect data about the radiation level of the target radiation monitoring field. This data may include information such as the type, intensity, and energy distribution of the radiation, which is essential for assessing the radiation environment and taking corresponding safety measures. In some embodiments, the radiation detector can perform preliminary processing on the original acquired detection signal through an internal signal conditioning module and convert it into a format suitable for transmission. This can include amplifying weak signals, filtering out noise, converting signal forms, etc. to ensure the quality of the data and the reliability of transmission.
[0181] It should be understood that once the current radiation detection information is adjusted to a suitable state, the radiation detector can transmit the current radiation detection information to the processing control module. After receiving the current radiation detection information, the processing control module can perform further analysis, such as dose rate calculation, radiation type identification, trend analysis, etc. Based on these analysis results, the processing control module can generate a monitoring indication signal to provide the monitoring indication module with a basis for performing monitoring response operations. This can include triggering sound and light alarms, recording data, adjusting detection parameters, or notifying operators, etc.
[0182] Reference Fig. 9 According to some embodiments of the present 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 transmits the current radiation detection information to the processing control module through the radiation detector, which may include:
[0183] Step S901, transmitting current radiation detection information to an analog-to-digital conversion module through a radiation detector to convert the current radiation detection information from an analog signal into a digital signal;
[0184] Step S902: Transmitting the current radiation detection information converted into a digital signal to a processing control module.
[0185] In some embodiments of the present application, the nuclear power plant radiation signal monitoring device also includes an analog-to-digital conversion module, which is integrated in the integrated module and is responsible for converting the analog signal collected by the radiation detector into a digital signal. This conversion process is crucial for subsequent data processing and analysis because it enables the signal to be effectively 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 originally exists in the form of analog signals, which reflect the continuous changes in radiation levels. The function of the analog-to-digital conversion module is to convert these analog signals into digital signals, a process that usually 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 closest discrete values, and encoding is the process of converting these discrete values into digital form.
[0187] In step S902 of some embodiments, the analog-to-digital conversion module transmits the current radiation detection information converted into digital signals to the processing control module. The processing control module is the brain of the nuclear power plant radiation signal monitoring device, which is responsible for receiving these digital signals and performing further analysis and processing. These processes may include statistical analysis of radiation levels, trend prediction, anomaly detection, etc., to evaluate the current state and potential risks of the radiation environment.
[0188] Through this conversion process of the analog-to-digital conversion module, the nuclear power plant radiation signal monitoring device can convert analog radiation detection information into digital form, so that the monitoring data can be analyzed and processed more accurately. This digital information transmission method improves the transmission efficiency and accuracy of data, and also provides the possibility of realizing automated monitoring response and remote monitoring. In this way, the nuclear power plant radiation signal monitoring device can operate more flexibly and efficiently, ensuring that reliable monitoring data can be provided under various radiation levels, providing important support for the safe operation of nuclear power plants.
[0189] In short, the information transmission process in step S203 is the basis for ensuring that the monitoring device can operate effectively, which 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 the present application can realize continuous monitoring of radiation levels and respond to any abnormal situation in a timely manner, 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 according to the current radiation detection information;
[0191] In the nuclear power plant radiation signal monitoring method of the present application, step S204 is a key link, which involves how the processing control module generates a monitoring indication signal according to 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 the built-in algorithm and preset thresholds to analyze the radiation detection information to achieve statistical analysis, trend prediction, anomaly detection, etc. of the radiation level of the target radiation monitoring field, so as to evaluate the current status and potential risks of the radiation environment.
[0193] In some embodiments, the preset threshold value 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 to indicate that the radiation environment is safe and no special measures are required. This monitoring indication signal can be a simple status indication, such as keeping a green light on, indicating normal operation. However, if the radiation level exceeds the preset threshold value, the processing control module can generate a monitoring indication signal to indicate possible risks or emergencies. This monitoring indication signal may include triggering an audible and visual alarm to immediately alert the operator to potential dangers; or starting a data recording program to perform a detailed analysis of the radiation event; or sending a notification to the control center to request further guidance or support.
[0194] In addition, the monitoring indication signal may also include further instructions to the radiation detector, such as switching detection branches to adapt to different radiation levels, or adjusting detection parameters to improve measurement accuracy. These automated response measures help ensure that the nuclear power plant radiation signal monitoring device of the embodiment of the present application 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 control module in step S204 generates a monitoring indication signal through intelligent analysis and judgment, providing an efficient and automated response mechanism for the radiation monitoring of the nuclear power plant. This not only improves the response speed and accuracy of the radiation signal monitoring device of the nuclear power plant, but also enhances the response capability of the nuclear power plant to radiation events, thereby better ensuring the safety of personnel and the environment.
[0196] According to some embodiments of the present application, the nuclear power plant radiation signal monitoring device further includes a communication module, which is disposed in the integrated module. After the control module generates a monitoring indication signal according to the current radiation detection information in step S204, the following may also be included:
[0197] The monitoring indication signal is sent to the distributed control system of the nuclear power plant through the communication module, so that the distributed control system of the nuclear power plant performs abnormal monitoring operations on the monitoring indication signal.
[0198] In some embodiments of the present application, the design of the nuclear power plant radiation signal monitoring device includes a communication module, which is integrated in the integrated module and is responsible for realizing data communication between the monitoring device and the nuclear power plant distributed control system (DCS). This communication function is crucial to ensure that the monitoring data can be transmitted to the control system in a timely manner and trigger the corresponding abnormal monitoring operation.
[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 abnormalities or emergencies. Once the monitoring indication signal is generated, the communication module can intervene and perform its data transmission duties.
[0200] Through the communication module, the monitoring indication signal is sent to the distributed control system (DCS) of the nuclear power plant. It should be emphasized that the DCS is a system that centrally monitors and controls the operation of the entire nuclear power plant. It can receive signals from the radiation signal monitoring device of the nuclear power plant and perform abnormal monitoring operations according to preset logic and safety protocols. These operations may include triggering alarms, recording events, adjusting process parameters, starting safety systems, or notifying operators.
[0201] In this way, the radiation signal monitoring device of the nuclear power plant can be closely integrated with the DCS to form a collaborative system. This integration not only improves the utilization efficiency of monitoring data, but also helps to enhance the response capability of the nuclear power plant to potential radiation risks. Through automated abnormal monitoring operations, the nuclear power plant can take timely measures to prevent the occurrence of radiation accidents or mitigate their impact, thereby protecting personnel safety and environmental health.
[0202] In step S205 of some embodiments, the monitoring instruction module receives a monitoring instruction signal from the processing control module, and performs a monitoring response operation according to the monitoring instruction signal.
[0203] In the nuclear power plant radiation signal monitoring method of the present application, step S205 describes the role of the monitoring indication module in the nuclear power plant radiation signal monitoring device, that is, receiving the monitoring indication signal from the processing control module and performing corresponding monitoring response operations according to these signals. This step is the final link in the entire monitoring process, which ensures that the monitoring data can be converted into actual response measures to ensure the safe operation of the nuclear power plant.
[0204] It should be noted that the monitoring and indication module is the executive part of the nuclear power plant radiation signal monitoring device, which is responsible for taking actions based on the monitoring and indication signals generated by the processing and control module, that is, performing monitoring response operations. The execution of monitoring response operations may include but is not limited to triggering the sound and light alarm system to warn on-site workers of abnormally elevated radiation levels; initiating emergency procedures, such as closing access to specific areas, or activating radiation protection facilities; and recording and reporting the details of radiation events for subsequent analysis and decision-making.
[0205] When the monitoring and indication module receives a monitoring indication signal, it will perform the corresponding monitoring response operation. For example, if the signal indicates that the radiation level exceeds the safety threshold, the monitoring and indication module may trigger a red alarm light and siren, and send an emergency notification to the control center through the communication system. In addition, the monitoring and indication module can also control other safety systems, such as automatically shutting down the radiation source or activating radiation shielding facilities.
[0206] In short, the monitoring indication module in step S205 is an indispensable component of the nuclear power plant radiation signal monitoring device, which ensures the practical application of the nuclear power plant radiation signal monitoring method of the present application and the safety of the nuclear power plant by performing the monitoring response operation. In this way, the nuclear power plant radiation signal monitoring device and method of the present application can not only provide accurate radiation monitoring data, but also take prompt action when necessary to protect personnel and equipment from radiation hazards.

[0208] Step S1001, in the power management module, converting the input voltage into a plurality of module operating voltages;
[0209] Step S1002, based on the integrated module, the operating voltage of each module is distributed to the radiation detector, the processing control module and the monitoring indication module.
[0210] In some embodiments of the present application, the design of the nuclear power plant radiation signal monitoring device includes a power management module, which acts as a bridge between the power module and the integrated module and is responsible for converting the input voltage into the working voltage required by each module in the device. The power management module is a key component to ensure the stable operation of the entire monitoring device, and it needs to provide accurate and stable power to meet the power requirements 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 power system inside the nuclear power plant. Then, the power management module converts this input voltage into a variety of different operating voltages through an internal voltage conversion circuit. These operating voltages may include but are not limited to specific voltages required to power key 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 integrated module, which is responsible for accurately allocating the operating voltage required by each module to the corresponding components. This allocation is based on the specific requirements and design parameters of each module to ensure that each module can operate at its optimal state. For example, a radiation detector may require a stable low voltage to ensure accurate measurement 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 embodiment of the present application shown in step S1001 to step S1002, the coordinated work of the power management module and the integrated module enables the nuclear power plant radiation signal monitoring device to ensure that all components can obtain appropriate power supply, thereby achieving efficient and reliable radiation monitoring. This design not only improves the stability and reliability of radiation monitoring, but also helps to extend the service life of the device and reduce maintenance costs. In addition, precise power management also helps to reduce energy waste and improve the energy efficiency of the entire monitoring system. In this way, the nuclear power plant radiation signal monitoring device can provide a solid foundation for the safe operation of the nuclear power plant and ensure that the radiation level is accurately monitored and responded to in a timely manner.
