The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0031] Nuclear power plants use nuclear fission reactions to release energy and convert it into electricity to generate electricity. To ensure that nuclear reactions can proceed continuously and controllably, nuclear power plant operation and maintenance personnel continuously monitor the operation of the unit through the main control panel and alarm information.

[0032] The current means of monitoring and controlling the operating conditions of nuclear power units are mainly:

[0033] 1. The main control device displays the monitoring screen of the nuclear power unit on the monitor, and the operating personnel monitor the operating status of the unit by continuously tracking the display screen; 2. The main control device triggers alarm information for specific faults. When an abnormality is detected in the nuclear power unit, the operating personnel are reminded by an alarm sound; 3. The operating personnel observe the instrument data of the nuclear power unit equipment on site and report the data to realize the operation monitoring of the unit.

[0034] On this basis, the source of the unit operation monitoring information of the nuclear power unit operators is mainly concentrated on the display screen information of the main control equipment, the fault alarm information set for specific faults, and the instrument data observed on the spot. In these ways, if the fault screen is not observed, the problem cannot be found, and the prompt information for specific faults also needs to be confirmed by auxiliary faults with the help of the monitoring screen. When the alarm appears, it often leads to the loss of precious early response time, especially in the operation of nuclear power units. There are still some transient accidents, such as shutdown, reactor shutdown, island operation and other abnormal conditions. When the alarm appears, they are already in a serious transient accident state, and the fault discovery timing and response time are delayed, resulting in low abnormal response efficiency of nuclear power units, and unable to achieve effective and reliable unit operation control and early fault prevention.

[0035] The embodiment of the present application provides an operation prompt strategy for a nuclear power unit, which uses the collected operation data stream as the discrimination object and each data in the operation data stream as the discrimination granularity to implement monitoring of the operation status of the nuclear power unit and operation discrimination, and issues a voice broadcast when the operation data meets the discrimination conditions, and implements discrimination monitoring of the unit's operation status starting from small-grained data items, so that the operating personnel can timely and effectively understand the unit's operation status and whether there is a tendency for faults to occur, ensure that faults can be discovered, verified and prevented in advance, improve the abnormal response efficiency of the nuclear power unit, and ensure effective and reliable unit operation control.

[0036] In order to illustrate the technical solution described in this application, a specific embodiment is provided below for illustration.

[0037] Combination Figure 1 As shown, in some embodiments, a method for prompting operation of a nuclear power unit is provided, comprising:

[0038] Step 101, obtaining a plurality of data items to be monitored of a nuclear power unit, a judgment condition corresponding to each data item to be monitored, and voice prompt information.

[0039] The multiple data items to be monitored of the nuclear power unit, the judgment conditions corresponding to each data item to be monitored and the voice prompt information may be based on set content.

[0040] These data can be pre-configured through a configuration table, and during the implementation of nuclear power unit operating status monitoring, these set contents are read from the configuration table.

[0041] In the configuration table, configure several data items that need to be monitored, give appropriate logical criteria under each data item to form the discrimination conditions and configure the corresponding voice prompt information to realize the construction of data monitoring and early warning logic (including but not limited to the AND or logic, addition, subtraction, multiplication and division processing, delay comparison or multiple logic superposition between different parameters or thresholds in the discrimination conditions). This facilitates the effective expansion and adjustment of data items, facilitates data discrimination and operation prompts for different configurable data items, and also allows operators to query the data discrimination logic of the corresponding prompt information through the configuration table when hearing the voice prompt information.

[0042] In some implementations, based on the discrimination conditions corresponding to each data item to be monitored, a discrimination logic execution code corresponding to the data item to be monitored may be generated, so as to perform data comparison and discrimination based on the acquired data stream in subsequent steps.

[0043] Optionally, the data monitoring and early warning logic for multiple monitored data items read from the configuration table is written into a specific software program, such as Visual FoxPro (VFP for short) to generate corresponding judgment logic execution code, or the configuration content in the configuration table is automatically extracted by a specific software program (such as VFP) to form a corresponding judgment logic execution code.

[0044] In an optional example, the data items to be detected include, for example, the opening of the hydrogen cooling water valve, the liquid level of the control tank, the rod position of the R rod, etc. The configuration table is shown in the following table:

[0045]

[0046] Optionally, when the data item to be detected is the opening of the hydrogen cooling water valve, the judgment condition corresponding to the data item to be detected, for example, the deviation of the opening of the hydrogen cooling water valve from the set value reaches 10% and the corresponding power exceeds 100 megawatts, and the corresponding voice prompt information is, for example, "Please note that the opening of the hydrogen cooling water valve is abnormal."

[0047] Optionally, when the data item to be detected is the liquid level of the container control box, the judgment condition corresponding to the data item to be detected, for example, the liquid level of the container control box exceeds 1.9 meters or is less than 1.2 meters or the liquid level deviation in the set box exceeds 0.02 meters, and the corresponding voice prompt information is, for example, "Please note that the water level in the container control box is abnormal."

[0048] The data items to be detected and the related judgment conditions and voice prompt information configured in the configuration table can be adjusted based on the unit operation monitoring requirements.

[0049] Step 102, acquiring the operating data of the target equipment in the nuclear power unit to obtain an operating data stream.

[0050] Here, the operating data of the target equipment of the nuclear power unit is continuously acquired to obtain the corresponding operating data stream, and then the acquired operating data stream is used as the judgment object to implement the monitoring of the operating status of the nuclear power unit and the operation judgment.

[0051] The operation data stream may be obtained by collecting all operation data generated during the operation of the target device, or by collecting data related to core components in the target device.

[0052] During the implementation process, the auxiliary system can be used to obtain real-time data information of the target equipment in the unit, such as steam generator related parameters, unit valve opening data, temperature instrument data, pressure instrument data, chilled water pump operation data, etc., to obtain the corresponding data stream.

[0053] Step 103 , for each piece of data in the running data flow, when a target data item corresponding to the current data is matched from the data items to be monitored, data discrimination is performed on the current data using a target discrimination condition corresponding to the target data item.

[0054] In this step, for each data in the acquired data stream, it is necessary to match it based on the acquired multiple data items to be detected. In the case that the current data is matched and there is a corresponding target data item, corresponding data discrimination will be performed on it.

[0055] In an optional implementation, step 103 performs data discrimination on the current data using the target discrimination condition corresponding to the target data item, including:

[0056] Determine the target discrimination condition corresponding to the target data item; call the target discrimination logic execution code corresponding to the target discrimination condition to perform data discrimination on the current data.

[0057] The target discrimination logic execution code is stored in a code library, and the code library stores pre-built discrimination logic execution codes corresponding to a plurality of set discrimination conditions.

[0058] When the target discrimination logic execution code corresponding to the target discrimination condition is called to perform data discrimination on the current data, the current data corresponding to the target data item in the running data flow is used as the input of the code to trigger the corresponding data discrimination process.

[0059] Among them, the discrimination logic of each data item to be monitored corresponds to a discrimination logic execution code in a code library. With the help of the pre-generated discrimination logic execution code in the code library, the target discrimination logic execution code corresponding to the target data item is selected and executed, so as to quickly realize the data discrimination processing of the current data and improve the data processing timeliness.

[0060] Step 104: When the current data meets the target discrimination condition, a voice prompt operation is performed based on the target voice prompt information corresponding to the target data item.

[0061] Optionally, when executing, the voice prompt operation may be to directly make a voice announcement according to the target voice prompt information or to make a voice announcement after processing the target voice prompt information.

[0062] In this process, based on the judgment results, the corresponding target voice prompt information is directly called to make direct voice broadcast prompts of the operating data status of the nuclear power unit, effectively giving the prompt information to the relevant operating personnel.

[0063] In the optional implementation process, the VFP program uses the data monitoring and early warning logic to perform judgment processing on the operation data of the target equipment that needs to be monitored obtained from the auxiliary system. The operation data includes but is not limited to the analog quantity or logic quantity that needs to be monitored during the operation of the equipment.

[0064] When a target data item corresponding to the current data is matched from the data items to be monitored, the current data is subjected to corresponding data discrimination processing according to the target discrimination condition corresponding to the target data item. When the set condition is met, the corresponding voice prompt information is triggered to be broadcasted.

[0065] Therefore, data items related to transient accidents in nuclear power units and abnormal data items that require operating personnel to spend time to query and verify the status can be configured in advance into the configuration table, and then the corresponding judgment logic execution code can be formed in the VFP program.

[0066] In some optional examples, such as the evaporator valve, the VFP program extracts the real-time monitoring data of the evaporator collected in the auxiliary system during operation. The corresponding judgment logic in the VFP program is, for example, "the opening exceeds the experience opening of the power platform or the deviation from the required opening exceeds 10%". Based on the execution code corresponding to the judgment logic, when it is judged that the opening of the evaporator valve is abnormal, a prompt will be triggered immediately, and the corresponding voice will be called to directly inform the operator which evaporator has abnormal data; or, for example, RCP (Reactor Coolant Pump, reactor cooling pump) equipment and its lubricating oil pump start-up time judgment, when the lubricating oil pump meets the RCP equipment shutdown time requirement, the operator can shut down the oil pump. Under the existing method, the operator needs to retrieve the operation curve of the lubricating oil pump for real-time operation monitoring and judgment. In this embodiment, the real-time monitoring data of the RCP equipment during operation collected in the auxiliary system is extracted through the VFP program. The corresponding judgment logic in the VFP program is, for example, "the shutdown time of the lubricating oil pump of the RCP equipment is greater than 15 minutes, but not greater than 50 minutes". Based on the execution code corresponding to the judgment logic, when it is judged that the judgment condition is met, a prompt is triggered, and the corresponding prompt voice is retrieved for broadcasting, and a real-time reminder of the operation status of the unit equipment is issued to the operator, and the operator does not need to observe the operation time of the RCP oil pump through the operation curve of the oil pump.

[0067] This process can provide operators with convenient and effective unit operation prompts. Before a fault occurs, it can detect each detailed data item and provide abnormal prompts by identifying the data flow during unit operation, making it easier for operators to implement effective and reliable unit operation control and abnormal prevention.

[0068] In some optional implementation methods, when designing the voice prompt information, you can choose to use some more colloquial expressions, such as directly expressing "RCV017MP pressure" as "charging pressure", which makes it easier for operators to understand and respond to the voice prompt information.

[0069] In the above implementation process, the collected operation data stream is used as the discrimination object, and each data in the operation data stream is used as the discrimination granularity to implement the monitoring of the operation status of the nuclear power unit and the operation discrimination, and issue a voice broadcast when the operation data meets the discrimination conditions. Starting from small-grained data items, the discrimination monitoring of the unit operation status is implemented, so that the operating personnel can timely and effectively understand the unit operation status and whether there is a tendency for failure to occur, ensure that the failure can be discovered, verified and prevented in advance, improve the abnormal response efficiency of the nuclear power unit, and ensure effective and reliable unit operation control.

[0070] In an optional implementation, in step 104, when the current data meets the target discrimination condition, a voice prompt operation is performed based on the target voice prompt information corresponding to the target data item, including:

[0071] When the current data meets the target judgment conditions, if the nuclear power unit is in a specific operating state, the operating power of the nuclear power unit is obtained; if the operating power exceeds the threshold, the voice prompt operation is performed based on the target voice prompt information corresponding to the target data item.

[0072] Optionally, the operating power of the nuclear power unit is specifically the power generation power of the nuclear power unit, for example, the power of the generator in the nuclear power unit is used as the operating power of the nuclear power unit, or the power based on the nuclear reaction power of the nuclear reactor minus the conversion loss is used as the operating power of the nuclear power unit.

[0073] Optionally, the specific operating state is specifically an operating state corresponding to a transient event.

[0074] In some embodiments, if multiple consecutive data before the current data are judged to meet the target judgment conditions, or the number of data within a set time period before the current data that are judged to meet the target judgment conditions exceeds a quantity threshold, the nuclear power unit can be considered to be in a specific operating state.

[0075] In this case, if data anomalies frequently occur in large quantities in the data within a short period of time or in several pieces of data before the current data, it is considered that the nuclear power unit is in a specific operating state. For example, it can be considered that the nuclear power unit is in a state where a transient event is about to break out.

[0076] The transient event processing process, for example, during the shutdown process of a nuclear power unit, many parameters momentarily exceed the threshold and are judged to meet the judgment conditions, triggering a voice prompt, but they will automatically recover later.

[0077] When faced with a situation where a nuclear power unit is in a specific operating state, in an embodiment of the present application, power limit information is added. Once the current specific operating state is determined at the moment of shutdown, the operating power of the nuclear power unit is detected. If the operating power of the nuclear power unit is within a normal range, a voice prompt is not output for the current data that has been determined to meet the target determination conditions, that is, a voice prompt operation is not performed based on the target voice prompt information corresponding to the target data item. However, when it is determined that the operating power of the nuclear power unit exceeds the normal range, a voice prompt is output for the current data that has been determined to meet the target determination conditions, that is, a voice prompt operation is performed based on the target voice prompt information corresponding to the target data item.

[0078] For example, unit shutdown will cause the water level of the high-pressure heater to be at an abnormal height, which will trigger a voice prompt broadcast. After it has been detected and confirmed that the unit is currently in a specific operating state of shutdown, the water level data of the high-pressure heater in the current data of the unit's operating data stream, when it is determined that its water level meets the judgment conditions, the operating power of the nuclear power unit is additionally detected. If the power is normal, it is considered that there is no need to trigger a voice prompt broadcast of abnormal water level height, thereby reducing the interference of abnormal prompt information on operating personnel under specific operating conditions. If the power is abnormal, it is considered that the unit is indeed abnormal, and a voice prompt broadcast of abnormal water level height needs to be triggered to ensure that effective detection and prompt of abnormal data conditions of the unit can be achieved under the specific operating state of the unit.

[0079] In some optional implementations, priorities may be set for different data items, and corresponding voice prompt operations may be performed based on the priorities, such as performing voice prompt operations with a louder volume for data items with higher priorities, or performing voice prompt operations with shorter voice content.

[0080] In an optional embodiment, in step 104, when the current data meets the target discrimination condition, a voice prompt operation is performed based on the target voice prompt information corresponding to the target data item, including:

[0081] Determine the priority of the target data item of the current data; when the priority reaches the target priority standard, obtain the simplified version of the target voice prompt information, and perform the voice prompt operation according to the simplified version of the voice prompt information.

[0082] Alternatively, when the priority reaches the target priority standard and the data value of the current data exceeds the standard threshold by a set amount, a simplified version of the target voice prompt information is obtained, and a voice prompt operation is performed according to the simplified version of the voice prompt information.

[0083] The simplified version of the voice prompt information can be generated by deleting the cliché content in real time based on the target voice prompt information. Alternatively, the simplified version of the voice prompt information is a pre-generated voice information, which is directly called to implement voice broadcasting when the voice prompt operation is performed.

[0084] For example, for the voice prompt of the steam generator water level data item, when the current water level height data exceeds the height threshold and meets the judgment conditions, and it is determined that the steam generator water level data item has a higher priority, a special voice prompt will be made for the abnormal situation. In order to improve the prompt effect, the voice content can be simplified and a quick prompt can be achieved with a shorter voice broadcast. For example, the original "Please note" can be simplified by removing the "Please note" in the "Please note, the steam generator water level is too high". The simplified version of the voice prompt information is "The steam generator water level is too high".

[0085] In a different embodiment, for the voice prompt of the data item of the steam generator water level, when the current water level height data exceeds the height threshold and meets the judgment conditions, and it is determined that the priority of the data item of the steam generator water level is higher, the value of the current steam generator water level height data can be further judged. When its data value exceeds the standard threshold-a set amount, it is considered that the current steam generator water level height is significantly abnormal, and it is necessary to quickly make a voice prompt for the abnormal situation with a large degree of fluctuation in the current data value. The simplified voice prompt information is used to perform the voice prompt operation and quickly make an abnormal prompt.

[0086] The above process can give special voice prompts for data abnormalities under specific data items based on the priorities of pre-set data items, effectively reminding operating personnel to pay special attention to abnormal operating data of relevant data items, and can further give special voice prompts based on the abnormal fluctuation degree of data values ​​under specific data items, thereby saving operating personnel's response time to abnormal situations under specific operating conditions such as transient states, ensuring that faults can be discovered, verified and prevented in advance, further improving the abnormal response efficiency of nuclear power units, and ensuring effective and reliable unit operation control.

[0087] In some optional implementations, each data item to be monitored also corresponds to text prompt information.

[0088] The operation prompt method of the nuclear power unit in the embodiment of the present application also includes:

[0089] An information display window is provided. When the current data meets the target discrimination condition, the target text prompt information corresponding to the target data item is displayed in the information display window.

[0090] Optionally, the information display window is an independent window arranged in the user interface. When a voice prompt operation is performed, corresponding text prompt information can be displayed in the window to facilitate the query and review analysis of abnormal prompt operations.

[0091] In an alternative implementation, combining Figure 2 As shown, an information display window is displayed in the display interface, and the unit operation prompt log data corresponding to the voice prompt operation is displayed in the information display window.

[0092] The log data specifically includes:

[0093] 2024-04-15 17:48:43.226Please note that the flow rate of column A in the safety-critical plant water system is low. 2024-04-15 17:47:39.727Please note that the charging pressure is abnormal.

[0094] 2024-04-15 17:32:51.435Please note that the R stick moves

[0095] 2024-04-15 17:31:03.003Please note that the R stick moves

[0096] 2024-04-15 16:50:11.007Please note that all spent pool cooling pumps have been shut down.

[0097] 2024-04-15 16:30:46.830Please note that the turbine speed is abnormal.

[0098] 2024-04-15 16:23:13.347Please note that the temperature of the No. 3 bearing of the steam turbine is too high.

[0099] The log data includes: target text prompt information corresponding to the target data item to which the current data that meets the judgment condition belongs, that is, text prompt information corresponding to the voice prompt information used in the voice prompt operation. The log data may also include: date and time corresponding to each voice prompt operation.

[0100] Accordingly, in an optional embodiment, in step 104, when the current data meets the target discrimination condition, a voice prompt operation is performed based on the target voice prompt information corresponding to the target data item, including:

[0101] When the current data meets the target discrimination conditions, determine whether the data collector corresponding to the current data in the target device is in a faulty state; if it is determined to be in a faulty state, the target text prompt information corresponding to the target data item of the current data is displayed in the information display window, and the voice prompt operation is not performed based on the target voice prompt information corresponding to the target data item.

[0102] The data collector is, for example, a pressure detection instrument, a liquid level gauge, a thermometer, a power detection circuit, etc.

[0103] Taking the container control box as an example, the current data is the liquid level value of the container control box, the data item corresponding to the current data is the liquid level of the container control box, and the judgment condition is whether the liquid level value exceeds 1.9 meters or is lower than 1.2 meters, or the deviation between the liquid level values ​​measured by the two liquid level meters exceeds 0.02 meters. When the liquid level value of the container control box meets the judgment condition, it is necessary to perform a voice prompt operation based on the corresponding voice prompt information to implement a voice reminder.

[0104] However, if one of the level meters is broken, the detected level value of the control box will fluctuate frequently, resulting in it being judged as frequently exceeding the above-mentioned judgment conditions. This will frequently trigger voice reminders, causing excessive interference to the main control operator.

[0105] In the embodiment of the present application, the above processing method introduces the judgment of whether the data collector corresponding to the current data is in a fault state. When it is found that the data collector, such as an instrument, is in a fault state, the locking function is triggered.

[0106] Under this locking function, the data item corresponding to the current data will be locked, and when the data under the same data item exceeds the standard (is judged to meet the judgment conditions) again, the voice reminder will not be triggered again, but the corresponding text prompt information will still be displayed in the information display window, so as to realize the log recording of any situation, reduce the voice interference to the operating personnel, and keep the text record of the corresponding matters to facilitate event review and troubleshooting.

[0107] After the fault of the corresponding data collector in the target device is repaired, the data item corresponding to the current data can be unlocked. When the data under the same data item exceeds the standard (is judged to meet the judgment conditions) again, the voice reminder will be triggered normally and a sound prompt will be issued.

[0108] Among them, the locking processing of the data item can be achieved by setting a locking flag for the data item corresponding to the current data. When the data under the same data item that is subsequently set with a locking flag meets the target discrimination conditions, the voice prompt operation is directly performed without being based on the target voice prompt information corresponding to the target data item.

[0109] When it is detected that the fault state of the above-mentioned data collector corresponding to the current data in the target device is repaired and restored to a normal state, the locking mark of the aforementioned data item is canceled. When the data under the same data item whose locking mark is subsequently canceled meets the target judgment condition, step 104 is executed normally and a voice reminder is given for the data abnormality.

[0110] The embodiments of the present application also provide different implementation methods of the operation prompt method of a nuclear power unit.

[0111] See also Figure 3 , Figure 3 The process of the operation prompt method of the nuclear power unit provided in the embodiment of the present application is Figure 2 .like Figure 3 As shown, a method for prompting operation of a nuclear power unit comprises the following steps:

[0112] Step 301, determining that at least one target unit fails.

[0113] Target unit failures include, for example, unit shutdown, reactor shutdown, island operation, etc.

[0114] Step 302: from the nuclear power units, determine the unit equipment associated with each target unit fault as the target equipment, and select multiple data items from the operation data items of the target equipment as the data items to be monitored.

[0115] Each target unit fault is associated with the unit equipment, for example:

[0116] When the target unit fault is a unit shutdown, since the cause of the shutdown may be a high vibration signal of the turbine superimposed on a fault signal of the condenser, the unit equipment associated with the fault may include the turbine and the condenser.

[0117] When the target unit failure is a reactor shutdown, the shutdown may be caused by an abnormality in the circulating water pump required by the reactor or an abnormality in the cooling loop where the circulating water pump is located, which may cause the reactor temperature to be too high and cause a shutdown. Therefore, the unit equipment associated with the failure may include a circulating water pump, a cooling loop, etc.

[0118] Multiple data items are selected from the operating data items of the target device as the data items to be monitored, for example:

[0119] When the target device is a circulating water pump, the main pump motor bearing temperature, main pump motor winding temperature, main pump speed, main pump vibration frequency, main pump machine seal return water data, etc. can be selected from the operating data items of the circulating water pump.

[0120] When the target device is a cooling loop, loop flow, loop flow pressure, vacuum degree, etc. can be selected from the operating data items of the cooling loop.

[0121] When the target device is a steam turbine, the cylinder temperature, oil pressure value, cylinder speed, cylinder vibration amplitude, etc. can be selected from the operating data items of the steam turbine.

[0122] The above process, combined with the specific target unit fault, carries out the disassembly and determination of the fault-related equipment and equipment operation data, determines the equipment and related data items that need to be monitored in the nuclear power unit operation prompt processing, and realizes the disassembly of small-grained data collection objects and data discrimination objects based on large-grained faults, so as to implement targeted collection of the data stream of the target equipment involved in the specific fault, and through the discrimination of each data in the data stream and the abnormal prompt, the operating personnel can timely and effectively understand the unit operation status and whether there is a tendency for specific faults to occur, ensure that the fault can be discovered, verified and prevented in advance, improve the abnormal response efficiency of the nuclear power unit, and ensure effective and reliable unit operation control.

[0123] Step 303, obtaining multiple data items to be monitored of the nuclear power unit, the judgment conditions corresponding to each data item to be monitored, and voice prompt information.

[0124] Step 304, acquiring the operating data of the target equipment in the nuclear power unit to obtain an operating data stream.

[0125] Step 305 , for each piece of data in the running data flow, when a target data item corresponding to the current data is matched from the data items to be monitored, data discrimination is performed on the current data using the target discrimination condition corresponding to the target data item.

[0126] Step 306: When the current data meets the target discrimination condition, a voice prompt operation is performed based on the target voice prompt information corresponding to the target data item.

[0127] The implementation process of step 303 to step 306 is the same as the implementation process of the aforementioned step 101 to step 104, and will not be repeated here.

[0128] Step 307, according to different target data items, data statistics are collected for corresponding voice prompt operations to obtain unit operation statistics.

[0129] The data statistics here may be frequency statistics, number statistics, distribution statistics of voice prompt operations executed under different target data items, etc.

[0130] Step 308: perform feature comparison between the unit operation statistical data and the fault model data of different unit faults.

[0131] The feature comparison may be a frequency comparison of voice prompt operations performed under the target data item, a number comparison, a similarity match of the distribution of voice prompt operations in different target data items, and the like.

[0132] Step 309: When it is determined through comparison that the unit operation statistics data conform to the model data characteristics of the target unit fault, a voice prompt operation for the target unit fault is performed.

[0133] This process introduces unit faults, fault model data of unit faults, and voice prompt operations of unit faults. On the basis of performing data anomaly detection and voice prompt processing based on small-grained data acquisition objects and data judgment objects, it reversely realizes the judgment and prompt processing of large-grained unit faults based on unit operation statistical data, which can ensure the accuracy of nuclear power unit fault detection, and then realize early discovery, early verification and early prevention of unit faults, improve the abnormal response efficiency of nuclear power units, and ensure effective and reliable unit operation control.
