[0049] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0050] In related technologies, such as Figure 1 As shown, Figure 1 The schematic diagram of the P panel in the main control room in one embodiment is shown in FIG. Figure 1 In RGL 003CC and RGL 006CC), select the control rod that needs to be lifted and manually operate the operating lever (i.e. Figure 1 The lifting of the control rod group of RGL 002CC and RGL 005CC. For example, if the control rod SB needs to be lifted by 5 steps and the control rod SC needs to be lifted by 5 steps, first, the control rod SB needs to be selected by manually operating the control switch, and then the operating rod needs to be lifted by 1 step. After the operating rod is reset, the operating rod needs to be manually operated to lift by 1 step until the control rod SB is lifted by 5 steps. The operator then manually operates the control switch to select the control rod SC and repeats the above process. Using traditional technology to lift the control rods of a total of nine rod groups, SA\SB\SC\SD\G2\G1\N2\N1\R, to the 5-step position, the entire operation time takes about 30 minutes. Moreover, the multiple operations of the control switch and the operating rod waste manpower and have a greater risk of human error. In view of the above technical problems, the present application proposes a control rod lifting method, device, equipment, storage medium and program product.

[0051] The control rod lifting method provided in the embodiment of the present application can be applied to Figure 2 The application environment includes a computer device, which may be a server, and its internal structure diagram may be as shown in FIG. Figure 2 As shown. The computer device includes a processor, a memory and a network interface connected through a system bus. Among them, the processor of the computer device is used to provide computing and control capabilities. The memory of the computer device includes a non-volatile storage medium and an internal memory. The non-volatile storage medium stores an operating system, a computer program and a database. The internal memory provides an environment for the operation of the operating system and the computer program in the non-volatile storage medium. The database of the computer device is used to store nuclear reactor related data. The network interface of the computer device is used to communicate with an external terminal through a network connection. When the computer program is executed by the processor, a control rod lifting method is implemented.

[0052] In one embodiment, Figure 3As shown, a control rod lifting method is provided, which is applied to Figure 1 The computer device in the example is used to illustrate, including the following steps:

[0053] S301: If a start signal for a reset selection switch is received, the current lifting rod position of each control rod is obtained.

[0054] In this embodiment, if Figure 4 As shown, Figure 4 This is a schematic diagram of the P disk station in the main control room in another embodiment, in which a reset selection switch (i.e. Figure 4 RGL 020CC), when receiving the start signal for the reset selection switch (that is, Figure 4 In the process of RGL 020CC rotating to starting), the control rod position measurement system can be used to detect the current lifting rod position of each control rod. The control rods include SA, SB, SC, SD, R, N2, N1, G2, and G1. It is assumed that the current lifting rod positions of each control rod obtained by the logic cabinet (computer equipment) are 3 steps, 5 steps, 0 steps, 5 steps, 5 steps, 5 steps, 5 steps, and 5 steps respectively.

[0055] S302, according to the current lifting rod position of each control rod and the preset lifting rod position of each control rod, determining the target control rod that has not reached the preset lifting rod position from the control rods.

[0056] Optionally, the preset lifting rod positions of each control rod may be 5 steps, 6 steps, etc., and the embodiment of the present application does not impose any limitation on this, as long as the control rods can be prevented from falling into the core.

[0057] In this embodiment, if the current lifting rod position of each control rod does not reach the preset lifting rod position, the control rod that has not reached the preset lifting rod position will be used as the target control rod. Taking the above steps as an example, the preset lifting rod position of each control rod is 5 steps, and the current lifting rod position of each control rod is 3 steps, 5 steps, 0 steps, 5 steps, 5 steps, 5 steps, 5 steps, 0 steps, and 5 steps respectively. The target control rods are SA, SC, and G2.

[0058] Furthermore, if the current lifting rod positions of the control rods are all 5 steps, all the control rods have reached the preset lifting rod positions, and there is no need to perform lifting operations on each control rod. The logic cabinet outputs a corresponding alarm prompt to indicate to the operator that each control rod has reached the preset lifting rod position.

[0059] S303, according to the preset lifting sequence of each target control rod, lifting each target control rod to a corresponding preset lifting rod position.

[0060] In this embodiment, the preset promotion order can be SA, SB, SC, SD, R, N2, N1, G2, G1, or it can be R, N2, N1, G2, G1, SA, SB, SC, SD, etc., and the embodiment of the present application does not impose any restrictions on this.

[0061] In this embodiment, it is assumed that the preset lifting rod position is 5 steps. Figure 5 As shown, the preset lifting sequence is SA, SB, SC, SD, R, N2, N1, G2, G1. After receiving the start signal for the reset selection switch (RGL020CC0), if the current lifting rod positions of each control rod obtained by the logic cabinet (computer equipment) through the rod position measurement system (i.e. 295) are 3 steps, 5 steps, 0 steps, 5 steps, 5 steps, 5 steps, 0 steps, 5 steps, then the target control rods are SA, SC, G2. SA includes the control rod GR1 (i.e. 45 ) and control rod GR2 (i.e. 46), the current rod lifting position is 3 steps, SC includes only one control rod (i.e. 65), the current rod lifting position is 0 step, G2 includes control rod GR1 (i.e. 31) and control rod GR2 (i.e. 32), the current rod lifting position is 0 step, then firstly perform the rod lifting operation on the target control rod SA, and increase the target control rod SA from 3 steps to 5 steps. After the rod lifting operation on the target control rod SA is completed, perform the rod lifting operation on the target control rod SC and the target control rod G2 in turn.

[0062] If the preset lifting order is R, N2, N1, G2, G1, SA, SB, SC, SD, the target control rod G2 is lifted first, and then the target control rod SA and the target control rod SC are lifted in turn.

[0063] In the above control rod lifting method, if a start signal for the reset selection switch is received, the current lifting rod position of each control rod is obtained, and further, according to the current lifting rod position of each control rod and the preset lifting rod position of each control rod, the target control rod that has not reached the preset lifting rod position is determined from each control rod, so that according to the preset lifting sequence of each target control rod, each target control rod is lifted to the corresponding preset lifting rod position. In this method, after receiving the start signal, the current lifting rod position of each control rod is detected, and the control rods that need to be lifted are intelligently selected, and the control rods that need to be lifted are further lifted in sequence according to the digital numerical control logic, without the need for manual control by the operator, thereby improving the lifting efficiency of the rod group control rods, reducing the waste of manpower, and the method can also avoid human errors caused by manual operation.

[0064] Figure 6 FIG. 1 is a flow chart of lifting each target control rod to a corresponding preset lifting rod position in one embodiment. Figure 6As shown, this embodiment relates to a possible implementation method of how to lift each target control rod to a corresponding preset lifting rod position according to a preset lifting sequence of each target control rod, including the following steps:

[0065] S601, sending a first control signal to a power supply cabinet corresponding to a target control rod according to a preset lifting sequence of each target control rod, wherein the first control signal is used to instruct the power supply cabinet to perform a rod lifting operation on the target control rod.

[0066] In this embodiment, according to the preset lifting order of each target control rod, the first control signal is sent to the power cabinet corresponding to the target control rod. Taking the above steps as an example, the logic cabinet first sends the first control signal to the target control rod SA, so that the power cabinet performs the lifting and wiping operation on the target control rod SA according to the first control signal.

[0067] S602, receiving a first feedback signal sent by the power supply cabinet, and updating a first count value corresponding to the target control rod according to the first feedback signal, wherein the first feedback signal is sent by the power supply cabinet after performing a rod lifting operation on the target control rod in response to the first control signal.

[0068] In this embodiment, after the power cabinet completes the rod lifting operation on the target control rod SA according to the first control signal, the power cabinet sends a first feedback signal to the logic cabinet, and the logic cabinet updates the first count value corresponding to the target control rod according to the first feedback signal. Assuming that the current rod lifting position of the target control rod SA is 4 steps, the first count value corresponding to the target control rod is 4. After receiving the first feedback signal, the first count value is updated, and the updated first count value is 5.

[0069] S603: If the updated first count value is equal to the count value corresponding to the preset rod lifting position of the target control rod, it is determined that the target control rod has been lifted to the corresponding preset rod lifting position.

[0070] In this embodiment, assuming that the preset rod lifting position is 5 steps, the count value corresponding to the preset rod lifting position is 5. When the updated first count value is equal to the count value corresponding to the preset rod lifting position of the target control rod, it is determined that the target control rod has been lifted to the corresponding preset rod lifting position. Taking the above step S602 as an example, the updated first count value is 5, which is equal to the count value corresponding to the preset rod lifting position, and the target control rod SA has been lifted to the corresponding preset rod lifting position.

[0071] Further, if the updated first count value is smaller than the count value corresponding to the preset lifting rod position of the target control rod, the next first control signal is sent to the power supply cabinet, and the first feedback signal sent by the receiving power supply cabinet is returned to obtain a new updated first count value, until the new updated first count value is equal to the count value corresponding to the preset lifting rod position of the target control rod, it is determined that the target control rod has been lifted to the corresponding preset lifting rod position.

[0072] In this embodiment, assuming that the count value corresponding to the preset rod lifting position is still 5, and the current rod lifting position of the target control rod SA is 1, the updated first count value of the target control rod SA is 2, and the logic cabinet needs to send the next first control signal to the power cabinet to instruct the power cabinet to continue the rod lifting operation on the target control rod SA. When the rod lifting operation of the target control rod SA is completed, the power cabinet sends the first feedback signal to the logic cabinet to update the count value, and the new updated first count value is 3. At this time, the target control rod SA has not reached the preset rod lifting position, and the next first control signal is repeatedly sent to the power cabinet until the new updated first count value is equal to the count value 5 corresponding to the preset rod lifting position of the target control rod, the target control rod SA reaches the preset rod lifting position, and the rod lifting operation of the target control rod SA is completed.

[0073] Furthermore, in the present method, the control rods of the nine rod groups SA, SB, SC, SD, R, N2, N1, G2, and G1 are all increased from 0 steps to 5 steps, and the whole process takes about 5-6 minutes to complete.

[0074] In the embodiment of the present application, according to the preset lifting sequence of each target control rod, a first control signal is sent to the power cabinet corresponding to the target control rod. When the lifting operation is completed, a first feedback signal sent by the power cabinet is received, and a first count value corresponding to the target control rod is updated according to the first feedback signal. When the updated first count value is equal to the count value corresponding to the preset lifting rod position of the target control rod, it is determined that the target control rod has been lifted to the corresponding preset lifting rod position and the updated first count value is less than the count value corresponding to the preset lifting rod position of the target control rod, and the first control signal is continuously sent to the power cabinet until the new updated first count value is equal to the count value corresponding to the preset lifting rod position of the target control rod. In the present method, the digital sequential control logic is used to replace the traditional analog manual control, thereby improving the efficiency of manual operation and reducing the waste of manpower.

[0075] Figure 7 FIG. 1 is a flow chart of sending a control command to a power supply cabinet in an embodiment. Figure 7 As shown, this embodiment relates to a possible implementation method of how to send a control command to a power cabinet according to a pulse width, including the following steps:

[0076] S701, receiving a second feedback signal sent by a power supply cabinet, where the second feedback signal is used to indicate that the power supply cabinet has received a first control signal.

[0077] In this embodiment, according to the preset lifting order of each target control rod, after the logic cabinet sends a first control signal to the power cabinet corresponding to the target control rod, the power cabinet sends a second feedback signal to the logic cabinet. The second feedback signal is used to indicate that the power cabinet has received the first control signal sent by the logic cabinet, that is, the rod lifting command sent by the logic cabinet to the power cabinet is valid.

[0078] S702, detecting the second feedback signal to obtain a pulse width.

[0079] The pulse width is the duration of the high level.

[0080] In this embodiment, the logic cabinet detects the second feedback signal to obtain a pulse width, and the pulse width may be 400ms, 500ms, 600ms, etc.

[0081] S703, sending a control command to the power supply cabinet according to the pulse width, where the control command is used to instruct the power supply cabinet to stop the lifting operation on the target control rod.

[0082] In this embodiment, if the pulse width is too narrow or too wide, it will cause the control rod to malfunction during the lifting process, and the fault needs to be further judged. If an emergency fault occurs, such as an equipment failure that causes the control rod to be unable to move or a risk of falling, or a direct failure to indicate the rod position or the unavailability of the USP function, it is necessary to suspend the handling of the fault first. If it is another type of non-emergency fault alarm, the lifting can continue after confirmation by the operator.

[0083] Specifically, if the pulse width is not within a preset threshold interval, a control command is sent to the power cabinet.

[0084] In this embodiment, the preset threshold interval range may be 300ms-500ms, or 350ms-450ms, etc., and this embodiment of the present application does not impose any limitation on this.

[0085] In this embodiment, taking the preset threshold interval range of 300ms-500ms as an example, when the pulse width of the second feedback signal is 200ms, it is determined that the pulse width is too narrow, or when the pulse width of the second feedback signal is 600ms, it is determined that the pulse width is too wide, at which time the logic cabinet sends a control command to the power cabinet, instructing the power cabinet to stop the rod lifting operation on the target control rod and output an alarm prompt message. After further confirmation of whether the fault is an emergency fault or a non-emergency fault, if it is an emergency fault, the fault is handled first, and if it is a non-emergency fault, the operator restarts the reset selection switch to continue the rod lifting operation.

[0086] Furthermore, if the pulse interval between two adjacent first control signals is less than a preset threshold, a control command is sent to the power supply cabinet, where the control command is used to instruct the power supply cabinet to stop the lifting operation on the target control rod.

[0087] Optionally, the preset threshold may be 800ms, 900ms, etc., which is not limited in the embodiment of the present application.

[0088] In this embodiment, the first control signals sent twice adjacently may be the first control signals sent twice adjacently for the same target control rod. For example, for the target control rod SA, the current rod lifting position of the target control rod SA is 3 steps, and the first control signals sent twice adjacently for the target control rod SA may be the first control signal sent for the first time (the control signal for lifting the target control rod SA from 3 steps to 4 steps) and the first control signal sent for the second time (the control signal for lifting the target control rod SA from 4 steps to 5 steps). It may also be the first control signals sent twice adjacently for different target control rods, for example, the target control rod SA and the target control rod SC, and the first control signals sent twice adjacently may also be the last first control signal for the target control rod SA (the control signal for lifting the target control rod SA from 4 steps to 5 steps) and the first first control signal for the target control rod SC (the control signal for lifting the target control rod SC from 0 steps to 1 step).

[0089] In this embodiment, it is assumed that the preset threshold is 800ms. When the first control signals of two consecutive times are less than 800ms, the logic cabinet sends a control command to the power cabinet, instructing the power cabinet to stop the operation of lifting the target control rod and output an alarm prompt message. After further confirmation of whether the fault is an emergency fault or a non-emergency fault, if it is an emergency fault, the fault is processed first. If it is a non-emergency fault, the operator restarts the reset selection switch to continue the operation of lifting the rod.

[0090] In the embodiment of the present application, the pulse width is obtained by detecting the second feedback signal, and when the pulse width is not within the preset threshold interval, a control command is sent to the power supply cabinet, or when the pulse interval between two adjacent first control signals is less than the preset threshold, a control command is sent to the power supply cabinet to detect the fault of the target control rod during the lifting process. Thus, the priority of the fault is obtained, so as to select to continue lifting or pause according to the priority of the fault, and ensure the stable operation of the lifting process.

[0091] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-mentioned embodiments can include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.
