The current start-stop control system for nuclear power units has not fully realized one-key start and stop, and many operations still require manual intervention, especially in the parameter adjustment and equipment status confirmation at key nodes.

[0076] Figure 1 is an optional flowchart of the nuclear power unit start-stop control method provided by the embodiments of the present application, Figure 1 The method in may include but is not limited to steps S101 to S105.

[0077] Step S101, obtain the start-stop sequence control information of the target nuclear power unit; wherein, the start-stop sequence control information includes a unit sequence control sequence, and the unit sequence control sequence is used to record the operation step information of the target nuclear power unit regarding start-stop control;

[0078] Step S102: In response to the start-stop control signal obtained by the target nuclear power unit, determine the target step sequence currently being executed according to the start-stop control signal and the start-stop sequence control information.

[0079] Step S103: Conduct a category analysis on the target step sequence to obtain sequence category information.

[0080] Step S104: In response to the sequence category information indicating that the target step sequence is an automatically executed sequence, control the target unit equipment matching the target step sequence to perform the start-stop control operation according to the target step sequence.

[0081] Step S105: In response to the sequence category information indicating that the target step sequence is a manually executed sequence, send the operation step information corresponding to the target step sequence to the target operation terminal matching the target step sequence to obtain a manual operation instruction matching the operation step information, and control the target unit equipment matching the target step sequence to perform the start-stop control operation according to the manual operation instruction and the target step sequence.

[0082] Steps S101 to S105 shown in the embodiments of the present application obtain the start-stop sequence control information of the target nuclear power unit; wherein, the start-stop sequence control information includes the unit sequence control sequence, and the unit sequence control sequence is used to record the operation step information of the target nuclear power unit regarding start-stop control; in response to the target nuclear power unit obtaining the start-stop control signal, determine the target step sequence currently being executed according to the start-stop control signal and the start-stop sequence control information. Conduct a category analysis on the target step sequence to obtain sequence category information, in response to the sequence category information indicating that the target step sequence is an automatically executed sequence, control the target unit equipment matching the target step sequence to perform the start-stop control operation according to the target step sequence, in response to the sequence category information indicating that the target step sequence is a manually executed sequence, send the operation step information corresponding to the target step sequence to the target operation terminal matching the target step sequence to obtain a manual operation instruction matching the operation step information, and control the target unit equipment matching the target step sequence to perform the start-stop control operation according to the manual operation instruction and the target step sequence. It can be seen from this that the present application records the operation step information of the target nuclear power unit regarding start-stop control by setting the start-stop sequence control information corresponding to the target nuclear power unit, and by distinguishing between automatically executed sequences and manually executed sequences for the currently executed target step sequence, corresponding start-stop control operations are respectively performed, thereby standardizing the start-stop operation procedures of the nuclear power unit, reducing the complexity of the nuclear power unit operation, and reducing the risk of human error.

[0083] In step S101 of some embodiments, start-stop sequence control information of the target nuclear power unit is obtained. The start-stop sequence control information records a series of steps required to be executed during the start and stop processes of the target nuclear power unit, covering all stages from start preparation to full operation of the target nuclear power unit, as well as from the operating state to safe shutdown. Among them, the unit sequence control sequence is composed of specific operation step information. The operation step information of the unit sequence control sequence includes specific operation content, execution conditions, expected results, and the target unit equipment and equipment parameters involved. By obtaining the start-stop sequence control information, the start-stop control device can provide accurate operation guidelines for subsequent automatic control and manual intervention, so as to achieve efficient and safe start-stop operations in the complex nuclear power unit control environment. The start-stop control device is a device used to control the start-stop control operation of the target nuclear power unit, and can be the control center device of the target nuclear power unit.

[0084] In step S102 of some embodiments, the start-stop control device responds to the start-stop control signal received by the target nuclear power unit. The start-stop control signal is a trigger signal sent to the start-stop control device, indicating that the start-stop operation has been initiated. The start-stop sequence control information details all the operation steps during the start-stop process of the target nuclear power unit, and the target step sequence is the unit sequence control sequence selected from the start-stop sequence control information according to the current start-stop control signal and the current state of the target nuclear power unit. The target step sequence will become the key information guiding the start-stop operation to ensure that the target nuclear power unit starts and stops safely and effectively according to the predetermined order and conditions.

[0085] Please refer to Figure 2 , in some embodiments, the start-stop sequence control information includes multiple unit sequence control sequences corresponding to different functional types. Step S102 may include but is not limited to steps S201 to S202:

[0086] Step S201, in response to the target nuclear power unit obtaining the start-stop control signal, perform functional type analysis according to the start-stop control signal to obtain execution function information;

[0087] Step S202, according to the execution function information matching the start-stop control signal, determine the target step sequence among the multiple unit sequence control sequences in the start-stop sequence control information.

[0088] In step S201 of some embodiments, the start-stop control device responds to the start-stop control signal obtained by the target nuclear power unit, analyzes the functional type of the signal, and obtains the execution function information. The start-stop control signal contains information about the functional type, that is, the execution function information. For example, the target nuclear power unit starts, stops, pauses, or resumes, etc. For another example, the functions corresponding to different systems of the target nuclear power unit. Each functional type corresponds to different operation requirements and execution logics. Through the functional type analysis, the start-stop control device can clarify the specific intention of the start-stop control signal and provide accurate guidance for subsequent operations.

[0089] In step S202 of some embodiments, the start-stop control device determines the target step sequence from multiple unit sequence control sequences in the start-stop sequence control information according to the execution function information. The start-stop sequence control information contains multiple unit sequence control sequences, and each unit sequence control sequence corresponds to a set of specific operation steps for realizing the start-stop control of the target nuclear power unit. The start-stop control device will screen out the target step sequence that matches the execution function information of the current start-stop control signal from multiple unit sequence control sequences. Through the matching target step sequence, the start-stop control device can ensure that the subsequent start-stop operations can be smoothly executed according to the predetermined order and conditions, so as to realize the safe and efficient start-stop of the target nuclear power unit.

[0090] In step S103 of some embodiments, the start-stop control device conducts an in-depth category analysis on the determined target step sequence. Further clarify the execution method of each step, that is, whether these steps need to be automatically executed or require manual intervention. Through this category analysis, the start-stop control device can divide the target step sequence into different categories, thereby obtaining the sequence category information. The sequence category information is used to indicate the category of the target step sequence, such as an automatically executed sequence or a manually executed sequence. The category division can improve the flexibility of the start-stop operation, enhance the adaptability of the start-stop operation, and enable the start-stop control device to better cope with complex start-stop scenarios and various possible situations.

[0091] Please refer to Figure 3 , in some embodiments, step S103 may include but is not limited to steps S301 to S302:

[0092] Step S301, conduct an operation object analysis on the operation step information corresponding to the target step sequence to obtain the operation object information of the corresponding target unit equipment;

[0093] Step S302, in response to the operation object information indicating that the target unit equipment is in the experimental maintenance stage, determine the target step sequence as a manually executed sequence.

[0094] In step S301 of some embodiments, the start-stop control device performs an operation object analysis on the operation step information corresponding to the target step sequence. The operation object analysis is to identify the target unit equipment associated with the target step sequence and obtain the operation object information of the target unit equipment. The operation object information is used to describe the current state, functions, and other information of the target unit equipment.

[0095] In step S302 of some embodiments, the state information of the target unit equipment is obtained based on the operation object information. If the operation object information indicates that the target unit equipment is in the experimental maintenance stage, then the start-stop control device determines the target step sequence as a manual execution sequence. The experimental maintenance stage means that the target unit equipment is undergoing specific tests or maintenance work, which requires direct intervention and supervision by the unit personnel to ensure the accuracy and safety of the operation steps. Therefore, determining such a target step sequence as a manual execution sequence can ensure that the unit personnel can flexibly adjust the operations according to the actual state and maintenance requirements of the target unit equipment, while avoiding the risks that may be brought by automated operations.

[0096] Please refer to Figure 4 , in some embodiments, step S103 may include but is not limited to steps S401 to S402:

[0097] Step S401, perform an operation object analysis on the operation step information corresponding to the target step sequence to obtain the operation object information of the corresponding target unit equipment;

[0098] Step S402, in response to the operation object information indicating that the target unit equipment meets the preset operation isolation conditions, determine the target step sequence as a manual execution sequence.

[0099] In step S401 of some embodiments, the start-stop control device performs an operation object analysis on the operation step information corresponding to the target step sequence. The operation object analysis is to identify the target unit equipment associated with the target step sequence and obtain the operation object information of the target unit equipment. The operation object information is used to describe the current state, functions, and other information of the target unit equipment.

[0100] In step S402 of some embodiments, the status information of the target unit equipment is obtained according to the operation object information. If the operation object information indicates that the target unit equipment meets the preset operation isolation condition, then the start-stop control device determines the target step sequence as the manual execution sequence. The operation isolation condition means that the target unit equipment needs to be subjected to operation isolation processing, that is, the target unit equipment needs to be isolated from other equipment of the target nuclear power unit to avoid damage between equipment and harm to the crew. The operation isolation processing often involves complex operation procedures and strict safety requirements, and requires the crew to perform careful operations and monitoring according to the actual on-site situation. Therefore, determining such a target step sequence as the manual execution sequence can ensure that the crew can flexibly adjust the operations according to the actual status and operation requirements of the target unit equipment, while avoiding the risks that may be brought by automated operations.

[0101] Please refer to Figure 5 , in some embodiments, step S103 may include but is not limited to steps S501 to S502:

[0102] Step S501, perform operation object analysis on the operation step information corresponding to the target step sequence to obtain the operation object information of the corresponding target unit equipment;

[0103] Step S502, in response to the operation object information indicating that the target unit equipment meets the preset control isolation condition, determine the target step sequence as the manual execution sequence.

[0104] In step S501 of some embodiments, the start-stop control device performs operation object analysis on the operation step information corresponding to the target step sequence. The operation object analysis is to identify the target unit equipment associated with the target step sequence and obtain the operation object information of the target unit equipment. The operation object information is used to describe the current status, functions, etc. of the target unit equipment.

[0105] In step S502 of some embodiments, the status information of the target unit equipment is obtained based on the operation object information. If the operation object information indicates that the target unit equipment cannot be directly controlled by the start-stop control device, that is, the preset control isolation condition is met, then the start-stop control device determines the target step sequence as a manual execution sequence. It can be understood that there are some target unit equipment in the target nuclear power unit that cannot be operated by the automation system due to technical limitations, safety requirements, or special working conditions. For example, the operation logic of some equipment is still difficult to be replaced by the automation system, or some equipment requires on-site personnel to perform manual inspections or adjustments, or during specific safety inspection phases, manual intervention is required to ensure the accuracy and safety of the operation. Determining such a target step sequence as a manual execution sequence can ensure that the unit personnel can flexibly adjust the operation according to the actual status and operation requirements of the equipment, while avoiding the risks that may be brought by automated operations.

[0106] Please refer to Figure 6 , in some embodiments, step S103 may include but is not limited to steps S601 to S602:

[0107] Step S601, perform an operation object analysis on the operation step information corresponding to the target step sequence to obtain the operation object information of the corresponding target unit equipment;

[0108] Step S602, in response to the operation object information indicating that the target unit equipment is set with nuclear power safety permissions, determine the target step sequence as a manual execution sequence.

[0109] In step S601 of some embodiments, the start-stop control device performs an operation object analysis on the operation step information corresponding to the target step sequence. The operation object analysis is to identify the target unit equipment associated with the target step sequence and obtain the operation object information of the target unit equipment. The operation object information is used to describe the current status, functions, etc. of the target unit equipment.

[0110] In step S602 of some embodiments, the status information of the target unit equipment is obtained based on the operation object information. If the operation object information indicates that the target unit equipment is set with nuclear power safety permissions, then the start-stop control device determines the target step sequence as a manual execution sequence. The existence of nuclear power safety permissions indicates that the operation of the target unit equipment has a high safety risk or needs to meet specific safety standards, so it is not suitable for direct control by the automation system. Determining such a target step sequence as a manual execution sequence allows the unit personnel to personally perform the relevant operations according to the requirements of the operation step information and safety permissions. Thereby ensuring the flexibility and adaptability of the operation of the target unit equipment and enhancing the overall safety and reliability of the start-stop operation.

[0111] Please refer to Figure 7, in some embodiments, step S103 may include but is not limited to steps S701 to S702:

[0112] Step S701, perform an operation object analysis on the operation step information corresponding to the target step sequence to obtain the operation object information of the corresponding target unit equipment;

[0113] Step S702, in response to the operation object information indicating that the target unit equipment meets the preset path switching condition, determine the target step sequence as the manual execution sequence.

[0114] In step S701 of some embodiments, the start-stop control device performs an operation object analysis on the operation step information corresponding to the target step sequence. The operation object analysis is to identify the target unit equipment associated with the target step sequence and obtain the operation object information of the target unit equipment. The operation object information is used to describe the current state, function, etc. of the target unit equipment.

[0115] In step S702 of some embodiments, obtain the status information of the target unit equipment according to the operation object information. If the operation object information indicates that the target unit equipment meets the preset path switching condition, then the start-stop control device determines the target step sequence as the manual execution sequence. Meeting the path switching condition means that the target unit equipment needs to switch between different operation modes, or the target unit equipment needs to perform specific working conditions such as refueling. Therefore, determining such a target step sequence as the manual execution sequence can enable the crew to ensure the overall safety and reliability of the start-stop operation when the target unit equipment switches between different operation modes.

[0116] In step S104 of some embodiments, the start-stop control device determines that the current target step sequence is an automatic execution sequence according to the analyzed sequence category information. The start-stop control device will perform automatic start-stop operations on the target unit equipment matching the target step sequence without manual intervention. Automatic control can improve operation efficiency and reduce errors caused by human factors. The start-stop control device will automatically identify the specific operation content to be executed according to the operation step information detailed in the target step sequence, including equipment start, stop, parameter adjustment, etc. In addition, during the execution of the automatic operation, the start-stop control device will continuously monitor the status and operation parameters of the equipment to ensure the safety and reliability of the operation. If any abnormal situation is detected during the execution, the start-stop control device will be able to adjust the operation strategy in time or take necessary protection measures to prevent damage to the target unit equipment or safety accidents. Thus, it can monitor the response of the equipment in real time to ensure the smooth progress of the start-stop operation.

[0117] Please refer to Figure 8, in some embodiments, step S104 may include but is not limited to steps S801 to S802:

[0118] Step S801, in response to the sequence category information indicating that the target step sequence is an automatically executed sequence, generate an automatic operation instruction according to the operation step information corresponding to the target step sequence, and determine the target unit equipment according to the target step sequence;

[0119] Step S802, after determining the target unit equipment, control the target unit equipment to perform start-stop control operations according to the automatic operation instruction in accordance with the target step sequence.

[0120] In step S801 of some embodiments, the start-stop control device, in response to the sequence category information, confirms that the target step sequence is an automatically executed sequence, and then generates an automatic operation instruction according to the operation step information corresponding to the target step sequence. The operation step information details the specific content, execution conditions, and expected results of each step, providing a basis for generating accurate automatic operation instructions. At the same time, the start-stop control device determines the target unit equipment that needs to be operated according to the operation step information of the target step sequence, so as to ensure that the automatic operation instruction can be accurately sent to the target unit equipment.

[0121] In step S802 of some embodiments, after determining the target unit equipment, the start-stop control device controls the target unit equipment to perform start-stop control operations according to the generated automatic operation instruction in accordance with the target step sequence. The start-stop control device can automatically identify the order and conditions of the operation steps, and accurately control the start and stop of the target unit equipment according to this operation step information. For example, if the target step sequence indicates that a certain auxiliary equipment needs to be started first and then the power of the main equipment is gradually increased, the start-stop control device will automatically execute the relevant operations in this order and monitor the situation of the target unit equipment in real time to ensure the smooth progress of the start-stop operation. Thereby improving the operation efficiency, reducing human errors, and enhancing the safety and reliability of the start-stop process of the target nuclear power unit.

[0122] Please refer to Figure 9 , in some embodiments, step S104 may further include but is not limited to steps S901 to S902:

[0123] Step S901, in response to the sequence category information indicating that the target step sequence is an automatically executed sequence, decompose the target step sequence into multiple step execution procedures;

[0124] Step S902, according to the multiple step execution procedures, control the corresponding target unit equipment to perform start-stop control operations.

[0125] In step S901 of some embodiments, after the start-stop control device confirms that the target step sequence is an automatic execution sequence in response to the sequence category information, it further decomposes the target step sequence into multiple step execution procedures. Thus, the target step sequence is subdivided into multiple smaller, more specific, and more manageable steps, namely step execution procedures. Each step execution procedure includes specific operation content, operation object, execution conditions, and expected results.

[0126] In step S902 of some embodiments, the start-stop control device controls the corresponding target unit device to perform start-stop control operations one by one according to these decomposed multiple step execution procedures. By refining the control method of steps, the start-stop control device can manage each operation link more precisely, ensuring that each step execution procedure is accurately executed in accordance with the predetermined order and conditions.

[0127] Please refer to Figure 10 , in some embodiments, step S902 may include but is not limited to steps S1001 to S1002:

[0128] Step S1001, for each step execution procedure, perform real-time monitoring on the target unit device corresponding to the target step sequence to obtain device monitoring parameters corresponding to the step execution procedure;

[0129] Step S1002, in response to the device monitoring parameters meeting the parameter conditions corresponding to the step execution procedure, control the target unit device to perform start-stop control operations.

[0130] In step S1001 of some embodiments, the start-stop control device performs real-time monitoring on the target unit device corresponding to the target step sequence for each step execution procedure, thereby obtaining device monitoring parameters directly related to the step execution procedure. The device monitoring parameters are key indicators for evaluating the status and operating conditions of the target unit device, such as temperature, pressure, flow rate, etc., and can reflect whether the target unit device is in a normal operating state and whether it meets the conditions for executing the next step execution procedure.

[0131] In step S1002 of some embodiments, the start-stop control device makes a response based on the obtained device monitoring parameters. If the device monitoring parameters meet the parameter conditions corresponding to the step execution procedure, the start-stop control device will control the target unit device to perform start-stop control operations. The start-stop control device will automatically judge whether the target unit device is ready for the next operation and trigger the corresponding control instruction when the parameter conditions are met. Through the control method of real-time monitoring and condition judgment, the automation degree of start-stop operations is improved, and it can ensure that each step execution procedure is executed under safe and appropriate parameter conditions, thereby effectively reducing the risks caused by abnormal device states or non-meeting parameter conditions.

[0132] In some specific embodiments, the target unit equipment includes a conveying pipeline, and the parameter conditions of the step execution procedure involve adjusting the flow rate of the conveying pipeline. For example, the flow rate of the conveyed material in the conveying pipeline is controlled within a certain range. In this application, a timer is set to connect to control devices such as pipeline valves. At regular time intervals, the control devices such as pipeline valves are controlled to open and close, so as to control the flow rate of the conveyed material. When the flow rate of the conveyed material is not within the specified range, the timer is paused. If the flow rate of the conveyed material is lower than the specified range, the control devices such as pipeline valves can be directly controlled to open the conveying pipeline to continuously release the conveyed material, or the opening amplitude of the control devices such as pipeline valves can be changed to change the flow rate of the conveyed material. If the flow rate of the conveyed material is higher than the specified range, the control devices such as pipeline valves are directly controlled to close the conveying pipeline. Similarly, the opening amplitude of the control devices such as pipeline valves can also be changed to change the flow rate of the conveyed material.

[0133] Please refer to Figure 11 , in some embodiments, before step S1002, it may include but is not limited to steps S1101 to S1102:

[0134] Step S1101, in response to the target unit equipment being a controllable type of equipment, obtain a plurality of pre-configured candidate equipment parameters corresponding to the target unit equipment;

[0135] Step S1102, based on the parameter conditions corresponding to the step execution procedure and the plurality of candidate equipment parameters, adjust the parameters of the target unit equipment to obtain equipment monitoring parameters.

[0136] In step S1101 of some embodiments, the start-stop control device responds to the situation where the target unit equipment is a controllable type of equipment. For such target unit equipment, the start-stop control device can obtain a plurality of pre-configured candidate equipment parameters related to the target unit equipment. The candidate equipment parameters correspond to the plurality of step execution procedures performed by the target unit equipment, and are parameters set for evaluating the start-stop operation of the target nuclear power unit when the target nuclear power unit performs a start-stop operation. They can be regarded as the parameters at multiple evaluation moments when the target unit equipment performs a start-stop operation. For example, when the reactor of the target nuclear power unit starts up, the pressure needs to be gradually increased so that the reactor reaches the critical state, that is, the number of fission neutrons is stable and the chain reaction can be self-sustaining. During this process, the pressure of the reactor needs to be gradually increased and the internal situation of the reactor needs to be monitored. Therefore, a plurality of candidate equipment parameters, that is, a plurality of pressure set values, are set to gradually complete the plurality of step execution procedures for increasing the reactor pressure. Usually, these pressure set values are the parameters corresponding to a certain stage of the reactor operation state. Therefore, they can be set independently according to the operation manual or operation experience corresponding to the target nuclear power unit.

[0137] In step S1102 of some embodiments, the start-stop control device adjusts the parameters of the target unit device based on the parameter conditions corresponding to the step execution procedure and multiple pre-configured candidate device parameters. By comparing the candidate device parameters with the parameter conditions specified in the step execution procedure, the start-stop control device selects the parameter conditions that best meet the current operation requirements and adjusts the target unit device to obtain device monitoring parameters. In this way, the start-stop control device can ensure that the device monitoring parameters of the target unit device have been optimized to the best state before the start-stop operation is performed, thereby improving the success rate and safety of the start-stop operation and reducing potential risks caused by improper device monitoring parameters.

[0138] In step S105 of some embodiments, the start-stop control device determines that the current target step sequence is a manual execution sequence according to the sequence category information. This means that the start-stop control device needs to send the operation step information corresponding to the target step sequence to the target operation terminal matching the target step sequence to ensure that the crew can obtain detailed and accurate operation step information, so as to manually perform the corresponding start-stop control operation.

[0139] After the operation step information is sent to the target operation terminal, the crew can perform manual operations based on this information. After the crew confirms and inputs the manual operation instructions on the operation terminal, the start-stop control device will receive these instructions and, in combination with the requirements of the target step sequence, perform start-stop control operations on the target unit device matching the sequence. Although this process involves manual intervention, through the detailed operation step information provided by the start-stop control device and the support of the target operation terminal, the risk caused by human error can be effectively reduced. Moreover, the start-stop control device still plays a supervisory and auxiliary role during the manual operation of the crew. It will monitor the status and operating parameters of the target unit device in real time to ensure that the manual operation instructions of the crew meet the safety and efficiency standards. If the operation of the crew does not match the requirements of the target step sequence, the start-stop control device can issue an alarm or prompt to remind the crew to correct the operation. By combining manual operation and system assistance, the flexibility of manual intervention is retained, and the monitoring and guidance functions of the automated system are utilized, thereby achieving higher safety and reliability in the complex start-stop operation of nuclear power units.

[0140] Please refer to Figure 12 , in some embodiments, step S105 may include but is not limited to steps S1201 to S1202:

[0141] Step S1201, in response to the sequence category information indicating that the target step sequence is a manual execution sequence, determine the target operation terminal according to the target step sequence;

[0142] Step S1202: After determining the target operation terminal, send the operation step information corresponding to the target step sequence to the target operation terminal, so that the target operation terminal displays the operation step information, obtains a manual operation instruction matching the operation step information, and controls the target unit equipment to perform start-stop control operations according to the manual operation instruction.

[0143] In step S1201 of some embodiments, the start-stop control device responds to the sequence category information, confirms that the target step sequence is a manual execution sequence, and determines the target operation terminal matching the target step sequence according to the target step sequence. The target operation terminal is the device for the crew to perform manual operations, which can display detailed operation step information and receive the manual operation instructions input by the crew, thus ensuring that the crew can obtain accurate operation guidance through the appropriate target operation terminal and providing support for the crew's manual operations.

[0144] In step S1202 of some embodiments, after determining the target operation terminal, the start-stop control device sends the operation step information corresponding to the target step sequence to the target operation terminal. After receiving the operation step information, the target operation terminal will display it so that the crew can clearly understand the specific content and requirements of each operation step. The crew inputs a matching manual operation instruction through the target operation terminal according to the displayed operation step information, and controls the target unit equipment to perform start-stop control operations according to the manual operation instruction. Thus, it is ensured that the crew can perform accurate operations according to the detailed operation step information, and the efficiency and safety of manual operations are improved through the real-time response and control of the start-stop control device to the manual operation instruction.

[0145] In an embodiment of the present application, start-stop sequence control information of a target nuclear power unit is obtained; wherein, the start-stop sequence control information includes a unit sequence control sequence, and the unit sequence control sequence is used to record operation step information of the target nuclear power unit regarding start-stop control; in response to the target nuclear power unit obtaining a start-stop control signal, and determining a currently executed target step sequence according to the start-stop control signal and the start-stop sequence control information. Category analysis is performed on the target step sequence to obtain sequence category information. In response to the sequence category information indicating that the target step sequence is an automatically executed sequence, according to the target step sequence, the target unit equipment matching the target step sequence is controlled to perform start-stop control operations. In response to the sequence category information indicating that the target step sequence is a manually executed sequence, the operation step information corresponding to the target step sequence is sent to a target operation terminal matching the target step sequence to obtain a manual operation instruction matching the operation step information, and according to the manual operation instruction and the target step sequence, the target unit equipment matching the target step sequence is controlled to perform start-stop control operations. Thus, it can be seen that in the present application, by setting the start-stop sequence control information corresponding to the target nuclear power unit, the operation step information of the target nuclear power unit regarding start-stop control is recorded, and by distinguishing between an automatically executed sequence and a manually executed sequence for the currently executed target step sequence, corresponding start-stop control operations are respectively performed, thereby standardizing the start-stop operation procedure of the nuclear power unit, reducing the complexity of the nuclear power unit operation, and reducing the risk of human error.
