[0002] Nuclear power engineering is an important part of modern energy, and nuclear power instrumentation is an important part of nuclear power engineering. Nuclear power instrumentation mainly refers to the instruments or equipment used to detect, measure, calculate, and display the physical parameters, material composition, and physical properties of various process systems in nuclear power plants. In order to ensure that the instruments of nuclear power plants can operate stably for a long time, regular maintenance and overhaul are required to ensure that all components of the instruments are in good working condition.

[0003] In related technologies, the instrument safety management system generally performs unified routine maintenance for nuclear power plant instruments within the area by dividing the plant area. However, the operating environments of instruments of different types and functions in different areas of the same plant area vary greatly, so the maintenance resources and maintenance frequencies they require are also different.

[0063] Now, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in a variety of different forms and should not be interpreted as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided to make the disclosure of the present application thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art.

[0064] In this embodiment, a maintenance method for nuclear power instruments is provided, such as Figure 1 As shown, the method includes:

[0065] Step 101: in response to the completion of a routine maintenance operation, obtaining operating environment data of at least one data category of a nuclear power instrument.

[0066] The nuclear power instrument in the embodiment of the present application is an instrument used to measure and monitor the operating status and parameters of a nuclear power plant, and may include pressure instruments, temperature instruments, power instruments, liquid level instruments, flow meters, speed instruments, etc.

[0067] Among them, routine maintenance operations are maintenance operations performed according to the first maintenance plan when the routine maintenance interval meets the first preset management cycle, so as to perform regular maintenance on nuclear power plant instruments. The routine maintenance interval is the first time length from the current moment to the triggering moment of the previous routine maintenance operation. The first maintenance plan is different routine maintenance plans customized for nuclear power plant instruments in different plant areas, which can be configured according to the model of nuclear power instruments, nuclear power plant operation requirements, etc. The first preset management cycle is used to determine the preset management cycle of routine maintenance operations, for example, routine maintenance operations are performed once a month, or once every 15 days, which is not specifically limited in the embodiments of the present application.

[0068] Specifically, the data categories of operating environment data include ambient temperature, ambient humidity, operating intensity, radiation, etc. Correspondingly, the operating environment data of nuclear power instruments include: ambient temperature value, ambient humidity value, operating intensity value, flow value, power value and radiation value, etc.

[0069] In this embodiment, after the routine maintenance operation is completed, operating environment data of at least one data category of the nuclear power instrument in the first preset management period of the routine maintenance operation is collected, so as to predict possible faults of the nuclear power instrument from the perspectives of ambient temperature, operating intensity or radiation, etc., and help to avoid the occurrence or further deterioration of instrument faults in a targeted manner.

[0070] In an actual application scenario, step 101, i.e., obtaining operating environment data of at least one data category of a nuclear power instrument, specifically includes the following steps:

[0071] Step 101 - 1 , determining a sampling period according to a triggering time of a routine maintenance operation and a first preset management cycle.

[0072] Step 101 - 2 , obtaining the maximum values ​​of the sampling data of the nuclear power instrument in multiple sub-periods in the sampling period, and calculating the average value of the maximum values ​​of the sampling data in the multiple sub-periods as the operating environment data.

[0073] The sampling period can be divided into multiple sub-periods according to a specified number or a specified duration. The specified number and the specified duration can be reasonably set according to actual needs. For example, if the sampling period is one month, one day is used as a sub-period.

[0074] In this embodiment, the first time period between the current routine maintenance operation and the previous routine maintenance operation is used as the sampling period for the data collection operation, that is, the data generated during the routine management period immediately following the current moment is collected to ensure the timeliness of the operating environment data. Thus, the operating environment data such as ambient temperature value, operating intensity value, flow value and radiation value are used to reflect the different working conditions of nuclear power instruments during the routine management period, which helps to detect whether the nuclear power instruments are in a safe operating state during the routine management period from multiple angles, and assists the system in accurate maintenance management.

[0075] For example, for ambient temperature, the maximum value of the ambient temperature of the nuclear power instrument in each sub-period can be obtained and marked as the peak temperature value, and the peak temperature values ​​of the nuclear power instrument in all sub-periods are summed and averaged to obtain the ambient temperature value. Similarly, for operating intensity, the maximum value of the continuous operating time of the nuclear power instrument in each sub-period is obtained and marked as the continuous operation value, and the continuous operation values ​​of the nuclear power instrument in all sub-periods are summed and averaged to obtain the operating intensity value. Similarly, for radiation intensity, the maximum value of the radiation intensity received by the nuclear power instrument in each sub-period is obtained and marked as the radiation intensity value, and the radiation intensity values ​​of the nuclear power instrument in all sub-periods are summed and averaged to obtain the radiation value.

[0076] Step 102 : Match the operating environment data with a preset data interval sequence according to the data category, and determine a target data interval in the preset data interval sequence that matches the operating environment data.

[0077] The preset data interval sequence includes a plurality of preset data intervals arranged in sequence. The preset data interval sequence corresponds to the data type one by one, that is, each type of operating environment data corresponds to a preset data interval sequence, for example, the ambient humidity corresponds to the ambient humidity interval sequence, the ambient temperature corresponds to the ambient temperature interval sequence, the operating intensity corresponds to the operating intensity interval sequence, and the radiance corresponds to the radiation interval sequence.

[0078] It is worth mentioning that the preset data interval can be associated with the second maintenance plan of the corresponding data type, and the second maintenance plans associated with preset data intervals of different data types are different. The second maintenance plans associated with multiple preset data intervals of the same data type can be the same or different, so as to facilitate the use of different second maintenance plans to perform appropriate maintenance operations on nuclear power instruments in different situations. Of course, the preset data interval may not be associated with the second maintenance plan, that is, when the operating environment data is within the preset data interval, no maintenance is required.

[0079] In one embodiment, the maintenance method of nuclear power instruments before step 102 also includes: obtaining specified operating environment data of the nuclear power instruments within a preset time period; determining the operating environment data range based on the maximum and minimum values ​​of the specified operating environment data; segmenting the operating environment data range to obtain multiple preset data intervals; and arranging the multiple preset data intervals in sequence to form a preset data interval sequence.

[0080] The preset period is the reset interval of the preset data interval sequence, which can be reasonably set according to the needs. At least one routine maintenance operation can be experienced within the preset period. For example, the preset period is configured as 1 year, and the first preset management cycle of the routine maintenance operation is configured as 1 quarter. At this time, 4 routine maintenance operations will be experienced within the preset period.

[0081] Specifically, the specified operating environment data may be operating environment data obtained during a sampling period within a preset period, or all operating environment data collected during a preset period, and the embodiments of the present application do not specifically limit this.

[0082] In this embodiment, the required specified operating environment data is obtained according to the preset time period, and the operating environment data range is defined by the maximum and minimum values ​​of the data, so as to determine all possible fluctuations in the operation of the nuclear power instrument. Then the large range is divided into multiple smaller preset data intervals to accurately distinguish different working conditions. Finally, multiple preset data intervals are arranged in order to form a preset data interval sequence, which can make the arrangement of the data intervals more orderly and clear, and facilitate management personnel to view, analyze and formulate corresponding maintenance plans.

[0083] Furthermore, the segmentation process may be segmentation according to a preset number or segmentation according to a preset numerical interval. The segmentation rules for the operating environment data ranges of different data types may be the same or different.

[0084] Exemplarily, the maximum and minimum values ​​of the environmental values ​​measured by all nuclear power instruments constitute the environmental range, the environmental range is divided into M1 environmental intervals, the average value of the maximum boundary value and the minimum boundary value of the environmental interval is marked as the environmental performance value of the environmental interval, and the environmental intervals are arranged in descending order according to the environmental performance values ​​to obtain an environmental sequence. The maximum and minimum values ​​of the operating intensity values ​​measured by all nuclear power instruments constitute the intensity range, the intensity range is divided into M2 intensity intervals, the average value of the maximum boundary value and the minimum boundary value of the intensity interval is marked as the intensity performance value of the intensity interval, and the intensity intervals are arranged in descending order according to the intensity performance values ​​to obtain an intensity sequence. The maximum and minimum values ​​of the radiation values ​​measured by all nuclear power instruments constitute the radiation range, the radiation range is divided into M3 radiation intervals, the average value of the maximum boundary value and the minimum boundary value of the radiation interval is marked as the radiation performance value of the radiation interval, and the radiation intervals are arranged in descending order according to the radiation performance values ​​to obtain a radiation sequence. Among them, M1, M2, and M3 are numerical constants, and the specific values ​​can be set by the management personnel.

[0085] Step 103: If the target data interval does not match the key data interval, and the target data interval is associated with a second maintenance plan, a characteristic maintenance operation of the nuclear power instrument is performed according to the second maintenance plan.

[0086] In this embodiment, if the target data interval does not match the key data interval, and the target data interval is associated with a second maintenance plan, indicating that the probability of abnormal conditions in the nuclear power instrument corresponding to the target data interval is low, then the second maintenance plan is used to perform personalized feature maintenance operations for the data category of the bad operating environment data. Thus, personalized maintenance plans are dynamically allocated to nuclear power instruments under different operating conditions such as operating environment, work intensity, and operating interference, and abnormal parts are maintained and repaired in time, which not only reduces the probability of failures and improves the operating reliability of nuclear power plants, but also avoids unnecessary maintenance work, reduces maintenance costs, and reduces the impact on the operation process of the nuclear power system as much as possible. Maintenance resources can also be deployed to other areas that require more maintenance, optimizing the utilization rate of maintenance resources.

[0087] In one embodiment, in step 103, a characteristic maintenance operation of the nuclear power instrument is performed according to the second maintenance plan, specifically including: if the routine maintenance operation of the nuclear power instrument is not performed, and the second time length from the current moment to the triggering moment of the previous characteristic maintenance operation meets the second preset management cycle, then the characteristic maintenance operation is performed according to the second maintenance plan.

[0088] Among them, after determining that the routine maintenance operation is completed, the second preset management cycle is determined based on the first preset management cycle. For example, if the maintenance frequency in the first preset management cycle is once a month, the second preset management cycle can be set to maintenance once a month or once every three months.

[0089] In this embodiment, when conventional maintenance operations of nuclear power instruments are not performed and the second preset management cycle of the characteristic maintenance operation is met, the characteristic maintenance operation is triggered. On the one hand, repeated maintenance is avoided and maintenance resources are saved. On the other hand, the triggering frequency of the characteristic maintenance operation is reasonably controlled to avoid the impact of the fault on the operation of the nuclear power plant.

[0090] Step 104: If the target data interval matches the key data interval, a key maintenance operation of the nuclear power instrument is performed according to the third maintenance plan corresponding to the key data interval.

[0091] The key data interval is determined based on the number of times the preset data interval is used as the target data interval for the feature maintenance operation.

[0092] It should be noted that the second maintenance plan is a maintenance plan customized for a certain type of data feature, that is, a plan for regular maintenance of instruments whose operating data in all plant areas is in a preset data interval, so as to solve abnormal problems in a certain type of situation. The second maintenance plans corresponding to different data types are different, for example, environmental maintenance plans, intensity maintenance plans, and radiation maintenance plans for different problems. Specifically, for abnormal ambient temperature, the ambient temperature maintenance plan can be regular cleaning of nuclear power instruments, and for abnormal flow, the ambient humidity plan can be instrument calibration. The third maintenance plan is a maintenance plan customized for key management objects, which can be configured with reference to the data category to which the key data interval belongs, the boundary value of the key data interval, and the number of times the key data interval is used as the target data interval for characteristic maintenance operations according to the preset data interval. The first maintenance plan, the second maintenance plan, and the third maintenance plan differ in maintenance subject, maintenance frequency (preset management cycle), and maintenance measures. The difference in maintenance subject causes a single instrument to form a cross-maintenance phenomenon when different maintenance plans are executed, and the difference in maintenance frequency matches the maintenance plan with the instrument operation status. The preset management cycle in the third maintenance plan is shorter than the preset management cycle in the first maintenance plan, that is, the maintenance frequency of the key maintenance operation is greater than the maintenance frequency of the routine maintenance operation. The maintenance measures include at least one of the following: cleaning, tightening, calibration, lubrication, and repair.

[0093] The maintenance method of nuclear power instruments provided in the embodiment of the present application, after performing routine maintenance operations on the instruments in the nuclear power plant, matches the operating environment data of the nuclear power instruments belonging to the same data category with the preset data interval sequence, and determines the preset data interval in which the operating environment data is located in the preset data interval sequence under the data category as the target data interval. First, match the target data interval with the pre-set key data interval. If the target data interval matches the key data interval, it means that the nuclear power instrument corresponding to the target data interval is often maintained within the preset time period, and the probability of abnormal conditions is high, and it is an object that needs to be paid special attention to, then the key maintenance operation of the nuclear power instrument is performed according to the third maintenance plan corresponding to the key data interval. If the target data interval does not match the key data interval, and the target data interval is associated with a second maintenance plan, it means that the probability of abnormal conditions in the nuclear power instrument corresponding to the target data interval is low, then for the data category of the poor operating environment data, the second maintenance plan is used to perform personalized feature maintenance operations. Thus, different maintenance plans can be dynamically allocated for nuclear power instruments under different operating conditions such as operating environment, work intensity and operating interference, so that the instruments of nuclear power plants can be cross-maintained in different maintenance plans, improving maintenance efficiency while ensuring the safe operation of instruments. At the same time, key maintenance objects can be extracted and maintained according to key maintenance plans, which is helpful for timely commissioning and maintenance of nuclear power instruments, ensuring the safe and stable operation of nuclear power instruments, and further ensuring the safety of instrument operation.

[0094] In actual application scenarios, maintenance operations can be performed by controlling corresponding maintenance equipment to maintain nuclear power instruments according to the maintenance plan, or by regularly sending reminder information containing maintenance measures of the maintenance subject and requirements in the maintenance plan to maintenance personnel according to the management cycle in the maintenance plan to remind maintenance personnel that manual maintenance is required.

[0095] In one embodiment, the preset data interval sequence includes a plurality of preset data intervals arranged in sequence. Before step 103 or step 104, the maintenance method of the nuclear power instrument further includes:

[0096] Step 201 : obtaining the number of times each preset data interval is used as a target data interval for a feature maintenance operation.

[0097] Step 202 , selecting key data intervals of different data categories from a plurality of preset data intervals of different data categories according to the number of times.

[0098] In this embodiment, by counting the number of times each preset data interval is selected as the target data interval and the related feature maintenance operations are performed, it can be known which preset data intervals are frequently hit. In other words, nuclear power instruments often use the second maintenance plan corresponding to the preset data interval for maintenance operations. The overall logic is that for instruments operating in high temperature, high humidity, high intensity, and high radiation environments, the maintenance frequency is higher, and the preset data intervals with a larger number of times are regarded as key data intervals. This helps to focus limited resources and time on the maintenance of key data, avoids unnecessary operations on unimportant data, improves the efficiency and effectiveness of data maintenance, and reduces the probability of operational failures of nuclear power instruments.

[0099] It is understandable that the number of times the preset data interval is used as the target data interval for feature maintenance operations can be compared with the number threshold, and if the number is greater than or equal to the number threshold, the preset data interval is used as the key data interval. The number thresholds for different data types can be the same or different.

[0100] Step 203, determining the first serial numbers of target data intervals of different data categories in the preset data interval sequence of the corresponding data categories, and the second serial numbers of key data intervals of different data categories in the preset data interval sequence of the corresponding data categories;

[0101] Step 204, if the first serial numbers of any two data categories are the same as the second serial numbers of any two data categories, then it is determined that the target data interval matches the key data interval;

[0102] Step 205 : If the first serial number of at most one data category is the same as the second serial number of at most one data category, it is determined that the target data interval does not match the key data interval.

[0103] In this embodiment, the first serial number and the second serial number of the target data interval and the key data interval belonging to the same data category in the preset data interval sequence of the data category are respectively determined, that is, the target data interval and the key data interval are in the sorting position of the preset data interval sequence. The first serial number and the second serial number are used as matching identifiers to determine the matching relationship between the target data interval and the key data interval. If at least two first serial numbers and the second serial numbers of the nuclear power instrument are the same, the match is successful, otherwise it fails. Therefore, according to the matching results, it can be determined which data categories of target data intervals correspond to nuclear power instruments that need to be focused on, and then maintenance resources can be better allocated to guide the formulation of maintenance strategies, so that different nuclear power instruments adopt different maintenance plans, improve the efficiency of maintenance processing, and ensure the operational safety of the nuclear power system.

[0104] Exemplarily, the nuclear power instrument that is maintained during the characteristic maintenance period is marked as a processing object, and the first serial number of the temperature sequence, humidity sequence, intensity sequence and radiation sequence in which the ambient temperature value, ambient humidity value, operating intensity value and radiation value of the processing object that has undergone maintenance operation are obtained and marked as temperature distribution value, humidity distribution value, intensity distribution value and radiation distribution value respectively. The distribution characteristics of the nuclear power instrument are generated in the form of temperature distribution value-humidity distribution value-intensity distribution value-radiation distribution value. The number of times the nuclear power instrument is marked as a processing object in the ambient temperature interval, ambient humidity interval, operating intensity interval and radiation interval is recorded as the processing value of the ambient temperature interval, ambient humidity interval, operating intensity interval and radiation interval respectively. M4 intervals with larger processing value values ​​in the ambient temperature interval, ambient humidity interval, operating intensity interval and radiation interval are marked as key intervals respectively. The key set is composed of M4 key intervals, and all key intervals in the key set are randomly combined in pairs and repeated combinations are eliminated to obtain several key combinations. Match any two elements in the assigned features with the key combination. If they match, the match is successful, and the processing object that matches the key combination is marked as a key maintenance object. In the next feature management cycle, a key maintenance plan is generated for the key maintenance object for unsuccessful operations. Among them, M4 is a numerical constant, and the specific value of M4 is set by the management personnel.

[0105] In one embodiment, the maintenance method of nuclear power instruments also includes: obtaining the total number of characteristic maintenance operations and key maintenance operations performed within a preset time period; if the total number is greater than or equal to a number threshold, resetting the preset data interval sequence and the first preset management cycle of routine maintenance operations.

[0106] In this embodiment, the total number of characteristic maintenance operations and key maintenance operations performed within a preset period is used as the reset condition of the first preset management cycle of the preset data interval sequence and the conventional maintenance operation, so as to ensure that the collected operating environment data can conform to the actual operating status of the nuclear power plant instrument. In addition, by resetting the preset data interval sequence and the conventional maintenance operation, the maintenance plan and strategy can be readjusted and optimized, and the maintenance cycle and maintenance content can be reset, so as to better meet the maintenance needs of the equipment and improve the maintenance effect.
