Description

Technical Field

[0001] The present application belongs to the field of nuclear power technology, and in particular relates to a detection method, device, electronic equipment, computer-readable storage medium and computer program product for a low-pressure heater of a nuclear power plant. Background Art

[0002] A nuclear power plant is a facility that uses the heat generated by nuclear fission reactions to generate electricity. Specifically, a nuclear power plant uses the energy released by nuclear fission to heat the coolant in the nuclear reactor, and the heated coolant transfers heat to the water in the steam generator, heating the water and converting it into high-temperature and high-pressure steam. This high-temperature and high-pressure steam enters the steam turbine, driving the blades of the steam turbine to rotate, and then drives the rotor of the generator coaxially connected to the rotating shaft of the steam turbine to rotate, thereby generating electrical energy.

[0003] The unit where the steam turbine is located also includes a low-pressure heater and a deaerator. The main function of the low-pressure heater is to use the steam extracted from the steam turbine to heat the condensate to increase the temperature of the condensate entering the deaerator. Since the deaerator is used to further heat the condensate and remove the oxygen in the condensate, and the increase in the temperature of the condensate entering the deaerator is beneficial to the deaerator to remove the oxygen in the condensate and reduce the heating steam consumed by the deaerator to heat the condensate. Since the condensate coming out of the deaerator will be supplied to the steam generator, the increase in the feed water temperature of the deaerator is beneficial to improving the steam parameters and increasing the work done by the steam, thereby improving the efficiency of the entire thermal system, and further improving the power of the generator of the nuclear power plant. That is, whether the low-pressure heater can work normally will affect the power of the generator of the nuclear power plant.

[0004] At present, when carrying out load testing on a low-pressure heater, multiple staff members are required to cooperate in the execution. For example, two staff members (assuming staff members A and B) are required to operate the start button of the isolation valve for controlling the low-pressure heater on the local control box. Since the start button of the isolation valve is at a certain distance from the isolation valve, two other staff members (assuming staff members C and D) are required to observe whether the isolation valve of the low-pressure heater responds to the button operation. In addition, other staff members are required to track the operation of the isolation valve.

[0005] Since the detection process requires a large number of staff to cooperate with each other, the detection efficiency is low. In addition, since different staff members communicate on-site, there is usually a delay in their communication, which may increase the closing time of the exhaust valve, increase the risk of isolation of the low-pressure heater, and increase the disturbance to the unit parameters, which in turn leads to inaccurate detection results. Summary of the invention

[0006] The embodiments of the present application provide a method, device and electronic equipment for detecting a low-pressure heater of a nuclear power plant, which can solve the problems of low detection efficiency and low accuracy of detection results of existing low-pressure heaters.

[0007] In a first aspect, an embodiment of the present application provides a method for detecting a low-pressure heater of a nuclear power plant, comprising:

[0008] Displaying a detection interface, the detection interface is used to display a start control and a closing limit switch icon of a check valve of a target low-pressure heater, wherein the target low-pressure heater is a low-pressure heater that currently needs to be detected; the detection interface is also used to display an icon of a steam turbine, an icon of an isolation valve of the target low-pressure heater, an icon of the check valve of the target low-pressure heater, and a connecting line connecting the icon of the steam turbine and the icon of the isolation valve;

[0009] When the start control is touched, a pulse closing instruction is sent to a processor of a target protection channel of the target low-pressure heater, so that the processor of the target protection channel generates a valve closing instruction according to the pulse closing instruction, and sends the valve closing instruction to an isolation valve of the target low-pressure heater, wherein the valve closing instruction is used to instruct the isolation valve to close, wherein the target protection channel is a logic channel that simulates an actual signal transmission path of the target low-pressure heater;

[0010] When the isolation valve is closed, the property value of the connection line is adjusted to a preset property value corresponding to when the isolation valve is in a closed state;

[0011] In the case where the check valve follows the isolation valve to close, adjusting the attribute value of the closing limit switch icon of the check valve to a preset attribute value corresponding to the check valve being in a closed state;

[0012] Sending an open pulse instruction to the processor of the target protection channel, so that the processor of the target protection channel generates a valve opening instruction according to the open pulse instruction, and sends the valve opening instruction to the isolation valve of the target low-pressure heater, wherein the valve opening instruction is used to instruct the isolation valve to open;

[0013] When the isolation valve is open, the property value of the connection line is adjusted to a preset property value corresponding to when the isolation valve is in an open state, and the property value corresponding to when the isolation valve is in an open state is different from the property value corresponding to when the isolation valve is in a closed state;

[0014] In the case where the check valve follows the isolation valve to open, the attribute value of the closing limit switch icon of the check valve is adjusted to a preset attribute value corresponding to when the check valve is in an open state, and the attribute value corresponding to when the check valve is in an open state is different from the attribute value corresponding to when the check valve is in a closed state;

[0015] When the start control is touched again, the detection of the target low-pressure heater is terminated.

[0016] In the embodiment of the present application, since the target protection channel is a logical channel that simulates the actual signal transmission path of the target low-pressure heater, when it is detected that the signal can be successfully transmitted in the target protection channel, it indicates that the actual signal transmission path of the target low-pressure heater can also successfully transmit the corresponding signal, that is, it indicates that the actual signal transmission path of the target low-pressure heater has passed the test. In addition, when the technical solution disclosed in the embodiment of the present application is used for detection, the user can start the detection of the target low-pressure heater in the detection interface, view the connection line in the detection interface to determine whether the isolation valve is closed or open, and view the closing limit switch icon of the check valve in the detection interface to determine whether the check valve is closed or open, that is, since the user can detect the target low-pressure heater through a detection interface, and the operation of the detection interface only requires the participation of a small number of staff, thus greatly improving the detection efficiency. And since the participating staff are all in the same place, and the environmental interference to the staff in the same place is very little, therefore, the interference to the detection results is reduced, thereby improving the accuracy of the detection results.

However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details.

[0039] In addition, in the description of the present application specification and the appended claims, the terms "first", "second", etc. are only used to distinguish the descriptions and cannot be understood as indicating or implying relative importance.

[0040] References to "one embodiment" or "some embodiments" etc. described in the specification of this application mean that one or more embodiments of the present application include specific features, structures or characteristics described in conjunction with the embodiment. Therefore, the phrases "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. appearing in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways.

[0041] In nuclear power plants, the main function of the low-pressure heater is to use the steam extracted from the turbine to heat the condensate to increase the temperature of the condensate entering the deaerator, thereby increasing the temperature of the water supplied to the steam generator.

[0042] The low-pressure heater includes two important valves: the isolation valve and the check valve. The main function of the isolation valve is to isolate the low-pressure heater from the rest of the system for maintenance or to cut off the flow of fluid in an emergency. It is installed close to the heater to prevent water from entering the exhaust line due to heat transfer tube rupture or drain blockage. The function of the check valve (also called a non-return valve) is to prevent the reverse flow of fluid, that is, to prevent the water or steam in the low-pressure heater from flowing back into the previous system. It is installed as close to the turbine as possible to prevent the steam from flowing back into the turbine during load rejection. Under normal operating conditions, the check valve opens with the opening of the isolation valve and closes with the closing of the isolation valve. Therefore, when testing the low-pressure heater, it is necessary not only to observe whether the isolation valve responds to the action of its start button, but also to observe whether the check valve moves following the action of the isolation valve.

[0043] Since the start button of the isolation valve is at a certain distance from the isolation valve, and the check valve is also at a certain distance from the isolation valve, when manually operating the start button of the isolation valve on site, observing the response action of the isolation valve on site, and observing the follow-up action of the check valve on site, more staff will be required to participate, and the detection efficiency is low. In addition, since the communication between the participating staff is directly on site, and the on-site environment may be noisy, it is easy to cause human errors. Therefore, when the low-pressure heater is tested in this way, the accuracy of the test results obtained based on the communication results is also low.

[0044] In order to improve detection efficiency and improve the accuracy of detection results, an embodiment of the present application provides a detection method for a low-pressure heater of a nuclear power plant.

[0045] In the detection method, a logical channel (i.e., a target protection channel) for simulating the actual signal transmission path of the low-pressure heater (i.e., the target low-pressure heater) to be detected is pre-set, and the start control and the closing limit switch icon of the check valve of the target low-pressure heater are displayed on the detection interface, and the connection relationship between the isolation valve and the check valve of the steam turbine and the low-pressure heater represented by icons and connecting lines is displayed. When the start control is touched, the isolation valve of the target low-pressure heater is instructed to perform a closing action or an opening action by communicating with the processor of the target protection channel, and the attribute value of the displayed connecting line is set to the corresponding attribute value when the isolation valve is in a closed state or an open state according to whether the isolation valve performs a closing action or an opening action, and the attribute value of the closing limit switch icon of the check valve is set to the corresponding attribute value when the check valve is in a closed state or an open state according to whether the check valve follows the isolation valve to perform a closing action or an opening action.

[0046] The following describes the detection method of the low-pressure heater of a nuclear power plant provided in an embodiment of the present application in conjunction with the accompanying drawings.

[0047] Figure 1 A flow chart of a detection method for a low-pressure heater of a nuclear power plant provided by an embodiment of the present application is shown. The detection method can be applied to electronic equipment, and is described in detail as follows:

[0048] S11, displaying a detection interface, wherein the detection interface is used to display the start control and the closing limit switch icon of the check valve of the target low-pressure heater, wherein the target low-pressure heater is the low-pressure heater currently to be detected; the detection interface is also used to display an icon of the steam turbine, an icon of the isolation valve of the target low-pressure heater, an icon of the check valve of the target low-pressure heater, and a connecting line connecting the icon of the steam turbine and the icon of the isolation valve.

[0049] Among them, the start control is a control for starting detection. Optionally, in addition to being used to start detection, the start control can also be used to end detection. For example, when the start control is touched for the first time, the start control will start detection, and when the start control is touched again, the start control will end detection. Optionally, when the detection interface displays the start control, it also displays the name of the start control. For example, when the start control includes two functions of starting detection and ending detection, "Start / Stop" is displayed in the surrounding area of ​​the start control. Optionally, in order to facilitate the user to intuitively know that it has been started, when the start control is touched to start detection, the start control is lit, and after the start control is touched to end detection, the start control stops being lit.

[0050] Among them, the target low-pressure heater is the low-pressure heater that needs to be detected. For example, assuming that there are two low-pressure heaters in the nuclear power plant, namely low-pressure heater 1 and low-pressure heater 2, and the low-pressure heater 1 currently needs to be detected, then the low-pressure heater 1 is the above-mentioned target low-pressure heater.

[0051] In the embodiment of the present application, when the user starts the function for detecting the low-voltage heater in the electronic device, the detection interface is displayed. Optionally, if the function of the low-voltage heater is started by a corresponding application, the detection interface is displayed after the application is opened.

[0052] In the embodiment of the present application, the detection interface may not be divided into regions. In this case, the detection interface is equivalent to a display area, in which the start control, the closing limit switch icon of the check valve, the connection relationship between the steam turbine and the target low-pressure heater, etc. are displayed. Of course, in order to improve the readability of the displayed information, the detection interface can be divided into at least two areas. In this case, type-related information can be displayed in the same area to facilitate user viewing. For example, assuming that the detection interface is divided into two areas, area 1 and area 2 are obtained, then the start control is displayed in area 1, and the closing limit switch icon of the check valve, the icon of the check valve, the icon of the steam turbine, the icon of the isolation valve, and the connecting line connecting the icon of the steam turbine, the icon of the check valve and the icon of the isolation valve are displayed in area 2.

[0053] It should be pointed out that the connection relationship represented by the steam turbine icon, the target low-pressure heater icon and the connecting line is the same as the actual connection relationship between the steam turbine and the target low-pressure heater, so as to improve the accuracy of the displayed connection relationship.

[0054] S12, when the above-mentioned start control is touched, a closing pulse instruction is sent to the processor of the target protection channel of the above-mentioned target low-pressure heater, so that the processor of the above-mentioned target protection channel generates a closing valve instruction according to the above-mentioned closing pulse instruction, and sends the above-mentioned closing valve instruction to the isolation valve of the above-mentioned target low-pressure heater, and the above-mentioned closing valve instruction is used to instruct the above-mentioned isolation valve to close, wherein the above-mentioned target protection channel is a logical channel that simulates the actual signal transmission path of the above-mentioned target low-pressure heater.

[0055] The above-mentioned closing pulse instruction is a pulse signal of a relatively short duration, such as a pulse signal of 2 seconds (S). When the start control is touched, a pulse signal of 2S is sent out, and after the processor of the target protection channel receives the pulse signal (i.e., the closing pulse instruction), it generates a corresponding closing valve instruction according to the preset closing valve instruction generation logic, and then sends the closing valve instruction to the isolation valve, which will release pressure to execute the action of closing the valve.

[0056] In the embodiment of the present application, the target protection channel includes not only a signal transmission method, but also logic for processing these signals through a corresponding processor.

[0057] Optionally, to improve the accuracy of the detection result, the detection of the target low-pressure heater is a load detection, and the load is the same as the load of the target low-pressure heater in actual operation.

[0058] S13, when the isolation valve is closed, adjusting the property value of the connection line to a preset property value corresponding to when the isolation valve is in a closed state.

[0059] Specifically, if the electronic device receives the isolation valve closing state information sent by the processor of the target protection channel (the isolation valve closing state information is used to indicate that the isolation valve is in a closed state), it is determined that the isolation valve is closed. Optionally, considering that the target low-pressure heater is usually safe when the isolation valve is in an open state, and the isolation valve is tested for the opening function after the closing function is tested, therefore, it can be determined here that the isolation valve is closed when the isolation valve closing state information is not received after the timeout, so as to improve the detection efficiency. For example, if the waiting time for receiving the isolation valve closing state information exceeds the preset first waiting time, it is determined that the isolation valve is closed.

[0060] When the electronic device determines that the isolation valve is closed, the property value of the connection line is set according to the property value corresponding to the preset isolation valve in the closed state. It should be pointed out that after the property value of the connection line is changed, the view of the connection line presented in the detection interface will change. For example, if the property value of the connection line is used to reflect the color of the connection line, then after the property value of the connection line is adjusted, the display color of the connection line will change accordingly. If the property value of the connection line is used to reflect the shape of the connection line (such as thickness), then after the property value of the connection line is adjusted, the shape of the connection line will change accordingly.

[0061] Optionally, when it is determined that the isolation valve is closed, the attribute value of the icon of the isolation valve of the target low-pressure heater may also be adjusted. If the attribute value of the icon of the isolation valve is used to reflect the color of the icon of the isolation valve, the icon of the isolation valve may be set to white according to the corresponding attribute value. Of course, in actual situations, it may also be set to other colors, which is not limited here.

[0062] S14, when the check valve follows the isolation valve to close, adjusting the attribute value of the closing limit switch icon of the check valve to a preset attribute value corresponding to when the check valve is in a closed state.

[0063] Under normal circumstances, after the isolation valve is closed, the pressure difference before and after the check valve becomes smaller, and the valve disc closes under the action of gravity, that is, the check valve will close following the closing of the isolation valve, and open following the opening of the isolation valve. For example, within a preset time after the isolation valve is closed, the check valve will also be closed.

[0064] In an embodiment of the present application, if the electronic device receives the check valve closing state information sent by the processor of the target channel (the check valve closing state information is used to indicate that the check valve is in a closed state), the electronic device determines that the check valve is closed, or if the waiting time for the electronic device to receive the check valve closing state information exceeds the preset check valve waiting time, the electronic device determines that the check valve is closed. After the electronic device determines that the check valve is closed, the attribute value of the closing limit switch icon of the check valve is adjusted according to the preset attribute value corresponding to the check valve in the closed state. For example, when the attribute value corresponding to the check valve in the closed state indicates that the closing limit switch icon of the check valve is lit, after the attribute value of the closing limit switch icon of the check valve is adjusted to the preset attribute value corresponding to the check valve in the closed state, the closing limit switch icon of the check valve displayed on the detection interface will be lit.

[0065] S15, sending an open pulse instruction to the processor of the target protection channel so that the processor of the target protection channel generates a valve opening instruction according to the open pulse instruction, and sends the valve opening instruction to the isolation valve of the target low-pressure heater, wherein the valve opening instruction is used to instruct the isolation valve to open.

[0066] After the electronic device detects the closing function of the isolation valve and the check valve, it continues to detect the opening function of the isolation valve and the check valve. Specifically, the electronic device sends an open pulse instruction to the processor of the target protection channel. The open pulse instruction is similar to the close pulse instruction and can also be a pulse signal of a shorter duration. When the processor of the target protection channel receives the open pulse instruction, it generates a corresponding valve opening instruction according to the preset valve opening instruction generation logic, and then sends the valve opening instruction to the isolation valve, and the isolation valve will execute the action of opening the valve.

[0067] S16, when the isolation valve is open, adjusting the property value of the connection line to a preset property value corresponding to when the isolation valve is in an open state, and the property value corresponding to when the isolation valve is in an open state is different from the property value corresponding to when the isolation valve is in a closed state.

[0068] Specifically, if the electronic device receives the isolation valve open state information sent by the processor of the target protection channel (the isolation valve open state information is used to indicate that the isolation valve is in an open state), it is determined that the isolation valve is open. In the case where the electronic device determines that the isolation valve is open, the attribute value of the connection line is set according to the preset attribute value corresponding to the isolation valve in the open state. Since the attribute value corresponding to the isolation valve in the open state is different from the attribute value corresponding to the isolation valve in the closed state, after the attribute value of the connection line is set according to the preset attribute value corresponding to the isolation valve in the open state, the view corresponding to the isolation valve in the open state presented by the connection line in the detection interface is different from the view corresponding to the isolation valve in the closed state. For example, if the attribute value of the connection line is used to reflect the color of the connection line, the color represented by the preset attribute value corresponding to the isolation valve in the open state can be orange, and the color represented by the preset attribute value corresponding to the isolation valve in the closed state can be gray, that is, different colors are used to represent different states of the isolation valve.

[0069] Optionally, when it is determined that the isolation valve is open, the attribute value of the icon of the isolation valve of the target low-pressure heater may also be adjusted. If the attribute value of the icon of the isolation valve is used to reflect the color of the icon of the isolation valve, the icon of the isolation valve may be set to blue according to the corresponding attribute value. Of course, in actual situations, it may also be set to other colors, as long as it is different from the corresponding color when the isolation valve is closed. This is not limited here.

[0070] Optionally, considering that it takes a certain amount of time for the isolation valve to open from closed, the attribute value of the isolation valve icon can be adjusted to be different from when the isolation valve is fully closed and also different from when it is fully open during the time from when the isolation valve is closed to when it is open (i.e., in the opening process). For example, when the isolation valve is in the fully open state, the color corresponding to the isolation valve icon is blue, and when the isolation valve is in the fully closed state, the color corresponding to the isolation valve icon is white. When the isolation valve is in the opening process, the attribute value of the isolation valve icon can be adjusted to be half blue and half white, so that the user can more accurately know the current state of the isolation valve.

[0071] S17, when the check valve follows the isolation valve to open, adjust the attribute value of the closing limit switch icon of the check valve to the preset attribute value corresponding to the check valve in the open state, and the attribute value corresponding to the check valve in the open state is different from the attribute value corresponding to the check valve in the closed state.

[0072] Specifically, if the electronic device receives the check valve opening state information sent by the processor of the target channel (the check valve opening state information is used to indicate that the check valve is in an open state), the electronic device determines that the check valve is open.

[0073] When the electronic device determines that the check valve is open, the attribute value of the closing limit switch icon of the check valve is set according to the preset attribute value corresponding to the check valve in the open state. Since the attribute value corresponding to the check valve in the open state is different from the attribute value corresponding to the check valve in the closed state, after the attribute value of the closing limit switch icon of the check valve is set according to the preset attribute value corresponding to the check valve in the open state, the view presented by the closing limit switch icon of the check valve in the detection interface is different from the view corresponding to the check valve in the closed state. For example, if the attribute value of the closing limit switch icon of the check valve is used to reflect whether the closing limit switch icon of the check valve is lit, the preset attribute value corresponding to the check valve in the closed state can indicate that the closing limit switch icon of the check valve is lit, and the preset attribute value corresponding to the check valve in the open state can indicate that the closing limit switch icon of the check valve stops being lit, that is, the two states of lighting and stopping lighting represent different states of the check valve.

[0074] It should be pointed out that the above steps S12 to S17 are control steps (also called sequential control procedures) executed sequentially.

[0075] S18, when the start control is touched again, the detection of the target low-pressure heater is terminated.

[0076] Specifically, after the electronic device detects that the start control is touched again, it means that the user wants to end this detection, and then the detection of the target low-voltage heater is stopped. The re-touch here refers to the re-touch of the start control after the detection is started by the start control. After the detection is ended, if a new detection of the target low-voltage heater is required, the touch of the start control does not belong to the re-touch here, but to the first touch.

[0077] Optionally, when the start control is touched again (ie, the condition for exiting the sequential program is triggered), the sequential control program will exit and all instructions issued by the sequential control program will be reset.

[0078] Optionally, considering that the sequential control test may need to be terminated in time during the test, such as the turbine protection signal needs to close the isolation valve in time, or the isolation valve needs to be opened in time when an abnormality occurs during the program execution, therefore, in the embodiment of the present application, in addition to ending the detection of the target low-pressure heater by starting the control, other methods can also be selected to end it. In addition, in order to avoid conflicts caused by the selected method, the priority of the command signal is defined in the sequential control program: the priority of the sequential control command (such as the command issued by the start control) is lower than the priority of the protection signal, and is lower than the priority of the manual opening and closing valve button command. For example, during the test, the user can perform emergency intervention by operating the opening and closing buttons on the main control room panel. Since the protection signal has a higher priority than the sequential control command, and the manual opening and closing valve button command is also higher than the sequential control command, the sequential control program automatically exits when the electronic device receives a protection signal or a manual opening and closing valve command.

[0079] In the embodiment of the present application, since the target protection channel is a logical channel that simulates the actual signal transmission path of the target low-pressure heater, when it is detected that the signal can be successfully transmitted in the target protection channel, it indicates that the actual signal transmission path of the target low-pressure heater can also successfully transmit the corresponding signal, that is, it indicates that the actual signal transmission path of the target low-pressure heater has passed the test. In addition, when the technical solution disclosed in the embodiment of the present application is used for detection, the user can start the detection of the target low-pressure heater in the detection interface, view the connection line in the detection interface to determine whether the isolation valve is closed or open, and view the closing limit switch icon of the check valve in the detection interface to determine whether the check valve is closed or open, that is, since the user can detect the target low-pressure heater through a detection interface, and the operation of the detection interface only requires the participation of a small number of staff, thus greatly improving the detection efficiency. And since the participating staff are all in the same place, and the environmental interference to the staff in the same place is very little, therefore, the interference to the detection results is reduced, thereby improving the accuracy of the detection results.

[0080] In some embodiments, the detection interface is further used to display a shutdown timeout icon, and after the shutdown pulse instruction is sent to the processor of the target protection channel of the target low-pressure heater, the detection interface further includes:

[0081] If the isolation valve closing status information sent by the processor of the target protection channel is not received within the preset first waiting period, the attribute value of the closing timeout icon is adjusted to the preset closing timeout attribute value, wherein the isolation valve closing status information is used to indicate that the isolation valve is closed.

[0082] When the electronic device receives the isolation valve closing status information sent by the processor of the target protection channel within the preset first waiting time, it indicates that the isolation valve closing has not timed out; otherwise, it indicates that the isolation valve closing has timed out.

[0083] Specifically, the first waiting time is set according to the standard closing time corresponding to the isolation valve, such as using the standard closing time as the first waiting time. Optionally, considering that the transmission of the signal requires a certain amount of time, the first waiting time can be set to a time greater than the standard closing time, and the difference can be determined according to the distance of signal transmission. For example, assuming that the standard closing time corresponding to the isolation valve is 4S, the first waiting time can be set to 20S. The standard closing time is the actual opening and closing time data measured by the instrumentation professionals on the actual valve on site during the overhaul.

[0084] In an embodiment of the present application, the moment when the closing pulse instruction is sent is recorded, the length of time between the moment and the current moment is counted, and it is determined whether the counted length of time is greater than the first waiting time. If it is greater than the first waiting time, and the isolation valve closing status information sent by the processor of the target protection channel is still not received, it indicates that the isolation valve closing has timed out. At this time, the attribute value of the closing timeout icon is adjusted to the pre-set closing timeout attribute value, which is beneficial for the user to promptly know that the isolation valve has timed out.

[0085] Optionally, the preset closing timeout attribute value can make the closing timeout icon light up to remind the user. Further, considering that the risk of closing the isolation valve is relatively high, if the isolation valve is not closed within the set time after the closing instruction is issued, the program will continue to execute the valve opening logic to open the isolation valve.

[0086] In some embodiments, the detection interface is further used to display an opening timeout icon, and after sending the opening pulse instruction to the processor of the target protection channel, it also includes:

[0087] If the isolation valve opening status information sent by the processor of the target protection channel is not received within the preset second waiting period, the attribute value of the opening timeout icon is adjusted to a preset first opening timeout attribute value, wherein the isolation valve opening status information is used to indicate that the isolation valve is open, and the first opening timeout attribute value is used to indicate that the isolation valve is open for a timeout.

[0088] When the electronic device receives the isolation valve opening status information sent by the processor of the target protection channel within the preset second waiting time, it indicates that the isolation valve is open without timeout, otherwise, it indicates that the isolation valve is open with timeout. Optionally, in order to ensure the safety of the detection, after determining that the isolation valve is open with timeout, it temporarily stays at the step of completing the opening timeout determination, so that the user can confirm whether there is a detection risk.

[0089] Specifically, the second waiting time is set according to the standard opening time corresponding to the isolation valve, such as using the standard opening time as the second waiting time. Optionally, considering that the transmission of the signal requires a certain amount of time, the second waiting time can be set to a time greater than the standard opening time, and the difference can be determined according to the distance of signal transmission. For example, assuming that the standard opening time corresponding to the isolation valve is 50S, the second waiting time can be set to 60S.

[0090] In an embodiment of the present application, the moment when the open pulse instruction is sent is recorded, the length of time between the moment and the current moment is counted, and it is determined whether the counted length of time is greater than the second waiting time. If it is greater than the second waiting time, and the isolation valve opening status information sent by the processor of the target protection channel is still not received, it indicates that the isolation valve opening has timed out. At this time, the attribute value of the opening timeout icon is adjusted to the pre-set first opening timeout attribute value, which is beneficial for the user to promptly know that the isolation valve has timed out.

[0091] Optionally, the preset first on-timeout attribute value may cause the on-timeout icon to be in a lighted state to remind the user.

[0092] In some embodiments, the detection interface is also used to display the parameter value of the parameter to be monitored, and the parameter value of the parameter to be monitored is affected by the closing of the isolation valve and the opening of the isolation valve. After the detection interface is displayed, it also includes:

[0093] The parameter values ​​of the above-mentioned parameters to be monitored are displayed on the above-mentioned detection interface.

[0094] Among them, considering that the water level of the deaerator of the nuclear power plant is automatically controlled (Automatic Control of Level in the Oxygen-Deaerating Heater, ACO) will rise after the isolation valve is closed, and will fall after the isolation valve is opened, the ACO water level can be used as one of the parameters to be monitored. Similarly, since the height of the ACO water level will affect the generator power of the nuclear power plant, the generator power can also be used as one of the parameters to be monitored. That is, in an embodiment of the present application, the parameter value of the ACO water level and / or the parameter value of the generator power can be displayed on the detection interface. Optionally, considering that the parameters affected by the closing and opening of the isolation valve also include the average temperature of a circuit and the high-pressure cylinder pressure, the above-mentioned parameters to be monitored may also include the average temperature of a circuit and / or the high-pressure cylinder pressure, which are not limited here.

[0095] Since the parameter value of the parameter to be monitored is affected by the closing and opening of the isolation valve, in the embodiment of the present application, the parameter value of the parameter to be monitored is displayed on the detection interface, which is helpful in assisting the user to determine whether the opening and closing functions of the isolation valve are normal.

[0096] Optionally, when the detection interface displays the parameter value of the parameter to be monitored, the parameter value of a specified time length may be displayed according to user needs. The specified time length may be 1 minute, 30 minutes, 1 hour, 24 hours, etc., which is not limited here.

[0097] In some embodiments, considering that when the number of parameters to be monitored is greater than 1, the user may only want to display the parameter values ​​of some of the parameters to be monitored, therefore, options corresponding to the parameters to be monitored may be provided for the user to select. At this time, before displaying the parameter values ​​of the parameters to be monitored on the detection interface, the following further includes:

[0098] The selection controls of the above-mentioned parameters to be monitored are displayed on the above-mentioned detection interface.

[0099] The selection control of the parameter to be monitored usually includes the parameter identifier of the corresponding parameter to be monitored, so that the user can distinguish different parameters to be monitored. The parameter identifier can be represented by a parameter name or a parameter code. For example, the selection control corresponding to the parameter to be monitored, which is marked with generator power, can be marked with generator power. When the selection control marked with generator power is touched, it means that the user wants the detection interface to display the parameter value corresponding to the generator power.

[0100] Optionally, when the number of parameters to be monitored is small, selection controls corresponding to all parameters to be monitored can be displayed on the detection interface; when the number of parameters to be monitored is large, a drop-down menu can be displayed on the detection interface. After the user pulls down the drop-down menu, the detection interface will display the corresponding selection controls for the parameters to be monitored, so as to make the detection interface more concise.

[0101] Correspondingly, the parameter value of the parameter to be monitored is displayed on the detection interface, including:

[0102] According to the selection control selected from the selection controls of the parameter to be monitored, the parameter value of the parameter to be monitored corresponding to the selected selection control is displayed on the detection interface.

[0103] In the embodiment of the present application, since the electronic device can display the parameter value corresponding to the parameter to be monitored corresponding to the selected selection control on the detection interface according to the selection control selected by the user, the display flexibility of the detection interface is improved.

[0104] Optionally, considering the high safety requirements of nuclear power plants, in practice, at least two signal transmission paths are usually set for the target low-pressure heater. In order to achieve comprehensive detection of the target low-pressure heater, it is necessary to simulate all signal transmission paths. By simulating all signal transmission paths, a number of target protection channels greater than 1 will be obtained, and then each target protection channel will be detected. At this time, after adjusting the attribute value of the closing limit switch icon of the above-mentioned check valve to the preset attribute value corresponding to the above-mentioned check valve in the open state, it also includes:

[0105] A1. Check whether there is still the above-mentioned target protection channel which has not received the off pulse command.

[0106] Among them, each target protection channel of the same target low-pressure heater is an independent and completely identical channel. Increasing the number of target protection channels is mainly to improve the safety of the nuclear power plant by adding redundant channels.

[0107] Specifically, after adjusting the attribute value of the closing limit switch icon of the check valve to the preset attribute value corresponding to the time when the check valve is in the open state, it indicates that the closing and opening of the isolation valve of a target channel have been detected, that is, the detection of the target low-pressure heater under the target channel has been completed. Therefore, it is judged whether there is still a target protection channel that has not received the closing pulse command, that is, it is judged whether there is a target protection channel of the target low-pressure heater that has not been detected, so as to reduce the probability of missing the detection of a certain target protection channel.

[0108] A2. In the case that there are still the target protection channels that have not received the off pulse instruction, a detection step is performed on one of the target protection channels that has not received the off pulse instruction. The detection step includes the following steps:

[0109] A closing pulse instruction is sent to the processor of the target protection channel so that the processor of the target protection channel generates a valve closing instruction according to the closing pulse instruction, and sends the valve closing instruction to the isolation valve of the target low-pressure heater; when the isolation valve is closed, the attribute value of the connecting line is adjusted to the preset attribute value corresponding to the isolation valve in the closed state; when the check valve follows the isolation valve to close, the attribute value of the closing limit switch icon of the check valve is adjusted to the preset attribute value corresponding to the check valve in the closed state; an opening pulse instruction is sent to the processor of the target protection channel so that the processor of the target protection channel generates an opening valve instruction according to the opening pulse instruction, and sends the opening valve instruction to the isolation valve of the target low-pressure heater, and the opening valve instruction is used to instruct the isolation valve to open; when the isolation valve is open, the attribute value of the connecting line is adjusted to the preset attribute value corresponding to the isolation valve in the open state; when the check valve follows the isolation valve to open, the attribute value of the closing limit switch icon of the check valve is adjusted to the preset attribute value corresponding to the check valve in the open state.

[0110] Specifically, the detection of each target protection channel is the same, that is, the above detection steps are the same as the above S12 to S17, and will not be repeated here.

[0111] A3. Return to the step of detecting whether there is still the target protection channel that has not received the off pulse instruction and subsequent steps, until there is no target protection channel that has not received the off pulse instruction.

[0112] Specifically, after all target protection channels have been detected, the above-mentioned step S18 may be performed.

[0113] In the embodiment of the present application, since each target protection channel of the target low-pressure heater is detected, that is, the target low-pressure heater is comprehensively detected, it is beneficial to improve the accuracy of the obtained detection results.

[0114] Optionally, when the number of target protection channels is greater than 1, in order to facilitate the user to promptly know which target protection channel is currently being detected, a corresponding icon is set for each target protection channel, and the above detection interface displays the icons of each of the above target protection channels, and represents the target protection channel currently being detected. For example, assuming that there are 2 target protection channels for the target low-pressure heater: target protection channel 1 and target protection channel 2, and the channel currently being detected is target protection channel 1, then the icon corresponding to target protection channel 1 is lit. Of course, in actual situations, the target protection icon currently being detected can also be distinguished by displaying different colors, which is not limited here.

[0115] In some embodiments, after the opening function of the isolation valve is tested, it is necessary to continue to test the untested target protection channel. The testing of an untested target protection channel is to first test the closing function of the isolation valve. However, after the isolation valve is changed from the open state to the closed state, the feed water temperature entering the deaerator will decrease, which will in turn increase the air extraction of the deaerator, which may cause the problem of difficulty in starting the unit. Therefore, the opening timeout confirmation control can be displayed on the detection interface. When the opening timeout confirmation control is touched, it means that the user believes that the opening timeout of the isolation valve at this time has no effect on the current detection. After that, the electronic device continues to test to improve the safety of the detection. That is, before the above-mentioned detection step is performed on one of the above-mentioned target protection channels that has not received the closing pulse instruction, it also includes:

[0116] When the time between sending the above-mentioned open pulse instruction and receiving the isolation valve opening status information sent by the processor of the above-mentioned target protection channel is greater than the preset second waiting time, the attribute value of the above-mentioned open timeout confirmation control is adjusted to be consistent with the preset second open timeout attribute value, and the above-mentioned second open timeout attribute value is used to indicate that the above-mentioned isolation valve opening timeout.

[0117] Correspondingly, the step of performing a detection step on one of the target protection channels that does not receive the off pulse instruction includes:

[0118] In the case where the above-mentioned opening timeout confirmation control is touched, a detection step is performed on one of the above-mentioned target protection channels that has not received the closing pulse instruction.

[0119] Since the duration between the moment of sending the open pulse instruction and the moment of receiving the isolation valve open status information sent by the processor of the target protection channel reflects the duration of the isolation valve opening, when it is determined that the duration of the isolation valve opening is greater than the preset second waiting time, it indicates that the time required for the isolation valve to open is longer. At this time, adjusting the attribute value of the open timeout confirmation control to be consistent with the preset second open timeout attribute value is conducive to prompting the user to promptly choose whether to confirm the open timeout, and only after the user confirms, the electronic device will detect the next target protection channel, thereby improving the safety of the detection.

[0120] Optionally, the preset second on-timeout attribute value can cause the on-timeout confirmation control to be in a lit state to remind the user.

[0121] In some embodiments, the detection interface is further used to display a continue detection confirmation control and a parameter value of a parameter to be monitored, the parameter value of the parameter to be monitored is affected by the closing of the isolation valve and the opening of the isolation valve, and when the opening timeout confirmation control is touched, the detection step is performed on one of the target protection channels that has not received the closing pulse instruction, including:

[0122] When the timeout confirmation control is touched, a condition prompt for continuing the test is displayed on the detection interface. The condition prompt includes prompting the user to check whether the parameter value of the displayed parameter meets the condition for continuing the test, and touch the continue detection confirmation control when the condition for continuing the test is met;

[0123] In the case where the above-mentioned continuous detection confirmation control is touched, the detection step is performed on one of the above-mentioned target protection channels that has not received the off pulse instruction.

[0124] Specifically, the above conditional prompt can be displayed after determining that the isolation valve has been opened for a timeout. Of course, it can also be displayed immediately after the detection interface is opened, but a prompt control is added next to the conditional prompt, and when the electronic device determines that the isolation valve has been opened for a timeout, the prompt control is automatically marked, for example, the prompt control is automatically lit.

[0125] In the embodiment of the present application, since the above condition prompt is displayed on the detection interface, and the condition prompt includes relevant explanations on operating the opening timeout confirmation control, it is helpful for the user to obtain more information on operating the opening timeout confirmation control. In addition, since the detection is performed on one of the above target protection channels that has not received the closing pulse instruction only when the displayed continuous detection confirmation control is touched, the safety of the detection is improved.

[0126] In some embodiments, the detection interface is also used to display operating instructions for detecting the target low-pressure heater, and the operating instructions include steps determined by all steps from the step of sending a closing pulse command to the processor of the target protection channel of the target low-pressure heater when the start control is touched to the step of adjusting the attribute value of the closing limit switch icon of the check valve to a preset attribute value corresponding to the time when the check valve is in an open state.

[0127] Specifically, the corresponding steps can be determined according to the above steps S12 to S17, and these steps are part or all of the information of the operation instructions displayed on the detection interface. Since the detection interface displays the operation instructions, it is convenient for the user to know the steps performed to detect the target low-pressure heater.

[0128] Optionally, a prompt control is added next to each step of the operating instructions, and when the electronic device executes the step, the prompt control is lit, thereby further increasing the amount of information obtained by the user.

[0129] In some embodiments, considering that there may be multiple low-pressure heaters in a nuclear power plant, such as Figure 2 As shown, assuming that there are 7 low-pressure heaters in the nuclear power plant, but only low-pressure pressurizer 204, low-pressure pressurizer 205, low-pressure pressurizer 206, and low-pressure pressurizer 207 need to be tested, then these 4 low-pressure pressurizers are all target low-pressure heaters. Considering that the workload is large and the probability of problems occurring is also increased when multiple target low-pressure heaters are tested at the same time, corresponding detection time ranges can be set in advance for different target low-pressure heaters, and the corresponding target low-pressure heaters can be tested within the corresponding detection time range. That is, when the number of target low-pressure heaters is greater than 1, and a corresponding detection time range is set in advance for each of the above target low-pressure heaters, the processor of the target protection channel of the above target low-pressure heater sends a pulse-off instruction, including:

[0130] When the current time is within the detection time range corresponding to the target low-pressure heater, an off pulse command is sent to the target low-pressure heater.

[0131] The detection time range may be in days, weeks or months, which is not limited here.

[0132] Specifically, if the detection time range is in days, for example, if the detection time range of the target low-pressure heater 1 is specified to be December 1, the current date should also be December 1 to detect the target low-pressure heater 1. Since the corresponding target low-pressure heater is detected according to the preset detection time range, the detection is more orderly, which is conducive to improving the accuracy of the obtained detection results.

[0133] In order to further describe the detection method of the low-pressure heater of the nuclear power plant provided by the embodiment of the present application, the following is combined with Figure 3 The detection interface is described below.

[0134] Figure 3 A schematic diagram of a detection interface provided in an embodiment of the present application is shown.

[0135] exist Figure 3In the test interface, "Target low-pressure heater 1 test" is displayed, indicating that the target low-pressure heater is currently being tested. "001KG" indicates the start button; "ABP402VV" indicates the model of the isolation valve, "401VV" indicates the model of the check valve, "001KG ACK" indicates the check confirmation control, and "401VV5" indicates the closing limit switch icon of the check valve.

[0136] The detection interface is mainly divided into two areas, one area is used to display operation instructions, and the other area is used to display prompt information.

[0137] For areas that display operating instructions:

[0138] The operation instructions provide 8 steps, and the leftmost of each step corresponds to a prompt control, which is marked to indicate that the step is currently being executed. For example, if the action of closing the isolation valve is currently being executed, the prompt control of the step corresponding to "01" is lit.

[0139] The area displaying the operation instructions also includes an off timeout icon (i.e., the circle corresponding to “off timeout” displayed in the area), an on timeout icon (i.e., the circle corresponding to “on timeout” displayed in the area), and an on timeout confirmation control (i.e., the circle corresponding to “confirm” displayed in the area).

[0140] For the area on the left side where the prompt information is displayed:

[0141] The user starts or ends the test by touching "001KG". When the test for channel 1 is completed, the prompt control corresponding to "Channel 1 OK" will be selected or lit. Similarly, when the test for channel 2 is completed, the prompt control corresponding to "Channel 2 OK" will be selected or lit.

[0142] The "parameter value display area" in this area is used to display the parameter values ​​of the parameters to be monitored, such as generator power and ACO water level.

[0143] The "option display area" in this area is used to display the options of the parameters to be monitored, such as the monitoring points corresponding to the generator power and the monitoring points corresponding to the ACO water level, etc. After the user selects the option corresponding to the parameter to be monitored in the option display area, the parameter value of the corresponding parameter to be monitored will be displayed in the "parameter value display area".

[0144] For the area on the right side where the prompt information is displayed:

[0145] When the isolation valve 402VV is opened, the connection line in this area can be set to orange, and when the isolation valve 402VV is closed, the connection line in this area can be set to gray. At the same time, the attribute value of the prompt control corresponding to the closing limit switch icon of the check valve, that is, "401VV5" will be adjusted to the attribute value corresponding to the isolation valve in the closed state.

[0146] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.

[0147] Corresponding to the detection method of the low-pressure heater of the nuclear power plant described in the above embodiment, Figure 4 A structural block diagram of a detection device for a low-pressure heater of a nuclear power plant provided in an embodiment of the present application is shown. For ease of explanation, only the parts related to the embodiment of the present application are shown.

[0148] Reference Figure 4 The detection device 4 of the low-pressure heater of the nuclear power plant is applied to the electronic device, and includes: a detection interface display module 41, a pulse off instruction sending module 42, a first attribute value adjustment module 43 of the connection line, a first attribute value adjustment module 44 of the limit switch icon, an open pulse instruction sending module 45, a second attribute value adjustment module 46 of the connection line, a second attribute value adjustment module 47 of the limit switch icon, and a detection end module 48. Among them:

[0149] The detection interface display module 41 is used to display the detection interface, and the above detection interface is used to display the start control and the closing limit switch icon of the check valve of the target low-pressure heater, wherein the above target low-pressure heater is the low-pressure heater currently to be detected; the above detection interface is also used to display the icon of the turbine, the icon of the isolation valve of the above target low-pressure heater, the icon of the check valve of the above target low-pressure heater, and the connecting line connecting the icon of the steam turbine and the icon of the isolation valve.

[0150] The closing pulse instruction sending module 42 is used to send a closing pulse instruction to the processor of the target protection channel of the target low-pressure heater when the above-mentioned start control is touched, so that the processor of the above-mentioned target protection channel generates a closing valve instruction according to the above-mentioned closing pulse instruction, and sends the above-mentioned closing valve instruction to the isolation valve of the above-mentioned target low-pressure heater, and the above-mentioned closing valve instruction is used to instruct the above-mentioned isolation valve to close, wherein the above-mentioned target protection channel is a logical channel that simulates the actual signal transmission path of the above-mentioned target low-pressure heater.

[0151] The first property value adjustment module 43 of the connection line is used to adjust the property value of the connection line to a preset property value corresponding to the state where the isolation valve is in a closed state when the isolation valve is closed.

[0152] The first limit switch icon attribute value adjustment module 44 is used to adjust the attribute value of the closing limit switch icon of the check valve to the preset attribute value corresponding to the check valve in the closed state when the check valve follows the isolation valve to close.

[0153] The pulse opening instruction sending module 45 is used to send an pulse opening instruction to the processor of the above-mentioned target protection channel, so that the processor of the above-mentioned target protection channel generates a valve opening instruction according to the pulse opening instruction, and sends the valve opening instruction to the isolation valve of the above-mentioned target low-pressure heater. The valve opening instruction is used to instruct the above-mentioned isolation valve to open.

[0154] The second property value adjustment module 46 of the connecting line is used to adjust the property value of the connecting line to the property value corresponding to the above-mentioned isolation valve being in the open state when the above-mentioned isolation valve is open, and the property value corresponding to the above-mentioned isolation valve being in the open state is different from the property value corresponding to the above-mentioned isolation valve being in the closed state.

[0155] The second adjustment module 47 of the attribute value of the limit switch icon is used to adjust the attribute value of the closing limit switch icon of the above-mentioned check valve to a preset attribute value corresponding to the above-mentioned check valve in the open state when the above-mentioned check valve follows the above-mentioned isolation valve to open, and the attribute value corresponding to the above-mentioned check valve in the open state is different from the attribute value corresponding to the above-mentioned check valve in the closed state.

[0156] The detection ending module 48 is used to end the detection of the target low-pressure heater when the start control is touched again.

[0157] In the embodiment of the present application, since the target protection channel is a logical channel that simulates the actual signal transmission path of the target low-pressure heater, when it is detected that the signal can be successfully transmitted in the target protection channel, it indicates that the actual signal transmission path of the target low-pressure heater can also successfully transmit the corresponding signal, that is, it indicates that the actual signal transmission path of the target low-pressure heater has passed the test. In addition, when the technical solution disclosed in the embodiment of the present application is used for detection, the user can start the detection of the target low-pressure heater in the detection interface, view the connection line in the detection interface to determine whether the isolation valve is closed or open, and view the closing limit switch icon of the check valve in the detection interface to determine whether the check valve is closed or open, that is, since the user can detect the target low-pressure heater through a detection interface, and the operation of the detection interface only requires the participation of a small number of staff, thus greatly improving the detection efficiency. And since the participating staff are all in the same place, and the environmental interference to the staff in the same place is very little, therefore, the interference to the detection results is reduced, thereby improving the accuracy of the detection results.

[0158] In some embodiments, the above detection interface is also used to display a shutdown timeout icon. The detection device 4 of the low-pressure heater of the nuclear power plant further includes:

[0159] The attribute value adjustment module of the closing timeout icon is used to adjust the attribute value of the closing timeout icon to a pre-set closing timeout attribute value after sending a closing pulse instruction to the processor of the target protection channel of the target low-pressure heater, if no isolation valve closing status information sent by the processor of the target protection channel is received within a preset first waiting period, wherein the isolation valve closing status information is used to indicate that the isolation valve is closed.

[0160] In some embodiments, the above detection interface is also used to display an opening timeout icon, and the detection device 4 of the low-pressure heater of the nuclear power plant further includes:

[0161] The attribute value adjustment module of the opening timeout icon is used to adjust the attribute value of the opening timeout icon to a preset first opening timeout attribute value after sending an opening pulse instruction to the processor of the target protection channel, if no isolation valve opening status information sent by the processor of the target protection channel is received within a preset second waiting period, wherein the isolation valve opening status information is used to indicate that the isolation valve is open, and the first opening timeout attribute value is used to indicate that the isolation valve is open for timeout.

[0162] In some embodiments, the detection interface is also used to display the parameter value of the parameter to be monitored, and the parameter value of the parameter to be monitored is affected by the closing of the isolation valve and the opening of the isolation valve. The detection device 4 of the low-pressure heater of the nuclear power plant also includes:

[0163] The parameter value display module is used to display the parameter value of the parameter to be monitored on the detection interface after the detection interface is displayed.

[0164] In some embodiments, the number of the above-mentioned parameters to be monitored is greater than 1, and the detection device 4 of the low-pressure heater of the nuclear power plant further includes:

[0165] A selection control display module is used to display a selection control of the parameter to be monitored on the detection interface before displaying the parameter value of the parameter to be monitored on the detection interface.

[0166] Correspondingly, the above parameter value display module is specifically used for:

[0167] According to the selection control selected from the selection controls of the parameter to be monitored, the parameter value of the parameter to be monitored corresponding to the selected selection control is displayed on the detection interface.

[0168] In some embodiments, the number of the target protection channels is greater than 1, and the detection interface is further used to display icons of each of the target protection channels. The detection device 4 for the low-pressure heater of the nuclear power plant further includes:
