[0054] In order to have a clearer understanding of the technical features, objectives, and effects of the present invention, the specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0055] It should be noted that the flowcharts shown in the accompanying drawings are only illustrative, and do not necessarily include all the contents and operations / steps, nor are they necessarily executed in the described order. For example, some operations / steps can be decomposed, while some operations / steps can be combined or partially combined. Therefore, the actual execution order may be changed according to the actual situation.

[0056] The block diagrams shown in the accompanying drawings are only functional entities, and do not necessarily correspond to physically independent entities. That is, these functional entities can be implemented in software form, or in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0057] Figure 1 is a program flowchart of a method for displaying digital procedures in a nuclear power plant according to an embodiment of the present invention. The method for displaying digital procedures in a nuclear power plant realizes the digital display of operating procedures (abbreviated as procedures).

[0058] Please refer to Figure 1 , the method for displaying digital procedures in a nuclear power plant may include step S1, step S2, step S3, and step S4.

[0059] Step S1 includes: obtaining an electronic procedure diagram; the electronic procedure diagram includes a plurality of procedure elements. The types of procedure elements are one of start, end, instruction text, criterion, parameter diagram, path line, and jump link.

[0060] In this step, the electronic procedure diagram can be a program flow chart made by process editing software such as Visio or Word. Figure 2 It is a program flow chart edited by Visio software in an embodiment. Among them, A1 is the original icon at the start, B1 is the original icon at the end, C1 is the original icon of the instruction text, D1 is the original icon of the criterion, E1 is the original icon of the parameter diagram, F1 is the original icon of the path line, and G1 is the original icon of the jump link.

[0061] Step S2 includes: classifying and parsing the electronic procedure diagram to obtain an intermediate file composed of multiple procedure function blocks; each procedure function block corresponds to each procedure element one by one.

[0062] In one embodiment, the electronic procedure diagram can be classified and parsed by executing step S21 to step S24.

[0063] Step S21 includes: classifying according to the types of each procedure element to determine the converted icon corresponding to each procedure element.

[0064] Please refer to Figure 2 , the icons of different types of procedure elements in the electronic procedure diagram are different. In one embodiment, the classification process of this step can include: classifying each procedure element based on the icon shape to obtain the type of each procedure element; determining the converted icon corresponding to each procedure element according to the preset procedure block and type correspondence table. Among them, the procedure block and icon correspondence table can include start icons, end icons, instruction text icons, criterion icons, parameter diagram icons, path line icons, and jump link icons that correspond to the start, end, instruction text, criterion, parameter diagram, path line, and jump link in sequence. It can be understood that in this embodiment, after determining the type of the procedure element, the converted icon corresponding to each procedure element can be determined in tabular form based on the procedure block and type correspondence table. Further, the start icon, end icon, instruction text icon, criterion icon, parameter diagram icon, path line icon, and jump link icon can refer to Figure 3 , where A2 is the start icon, B2 is the end icon, C2 is the instruction text icon, D2 is the criterion icon, E2 is the parameter diagram icon, F2 is the path line icon, and G2 is the jump link icon.

[0065] Since in some embodiments, the electronic procedure diagram may include the attribute information of each procedure element, and the attribute information includes the graphic information and text information of the procedure element. Correspondingly, in one embodiment, the classification process of this step may include: obtaining the graphic information of each procedure element according to the electronic procedure diagram; determining the converted icon corresponding to each procedure element according to the procedure block and the icon. It is easy to understand that compared with another embodiment of the classification process, the difference is that in this embodiment, the type of the procedure element is determined through the graphic information.

[0066] Step S22 includes: respectively converting the icon of each procedure element into the corresponding converted icon.

[0067] Step S23 includes: parsing each procedure element to determine the logical function of each procedure element. Specifically, this step can parse the text information of each procedure element to determine the logical function of each procedure element. Exemplarily, if the text information in a certain instruction text is "close a certain valve", then interpreting this text information shows that the function of this instruction text is to control a certain valve in the nuclear power plant to close; for another example, if the text information of a certain start is "start", then interpreting this text information shows that the function of start is the initiation or starting point of the program flow.

[0068] Step S24 includes: adding the logical function of the corresponding procedure element to each converted icon to obtain the multiple procedure function blocks described above.

[0069] In one embodiment, the types of the procedure function blocks are one of the start function block, end function block, instruction text function block, criterion function block, parameter diagram function block, path line function block, and jump link function block. Among them, the start function block corresponds to the procedure element "start" and is used to initiate the procedure. The end function block corresponds to the procedure element "end" and is used to end the procedure. The instruction text function block corresponds to the procedure element "instruction text" and is used to execute the corresponding instruction function according to the text information of the instruction text. The criterion function block corresponds to the procedure element "criterion" and is used to execute the corresponding judgment function according to the text information of the criterion. The parameter diagram function block corresponds to the procedure element "parameter diagram" and is used to execute the corresponding selection function according to the text information of the parameter diagram. The path line function block corresponds to the procedure element "path line" and is used to implement path guidance. The jump link function block corresponds to the procedure element "jump link" and is used to jump to the corresponding page according to the text information (i.e., the address) of the jump link.

[0070] Step S3 includes: performing parameter configuration on the intermediate file to set the functions of each procedure function block to form a basic procedure file; the functions of the procedure function blocks include outputting one or more of various process identification signals according to the manual operation signal, the logical function of the corresponding procedure element, and the input signal from the DCS system.

[0071] Among them, the manual operation signals may include a manual start signal, a manual end signal, a manual execution signal, a manual judgment signal, a manual selection signal, and a manual jump signal. It should be noted that the DCS system refers to the digital instrument control system of a nuclear power plant, and the input signals may include, but are not limited to, an automatic start signal and operating parameters.

[0072] In one embodiment, as Figure 3 shown, the icon of the path line function block includes an arrow, and the icon of the path line function block includes an active state and an inactive state; when the path line function block is in the active state, the arrow outputs a first process identification signal; when the path line function block is in the inactive state, the arrow outputs a second process identification signal. It should be noted that the path line function block enters the active state or the inactive state, which is controlled by the procedure function block connected thereto.

[0073] In one embodiment, as Figure 3 shown, the icon of the start function block may include a first rounded rectangle, and the first rounded rectangle includes an output port for connecting to the path line function block. Correspondingly, the process identification signal output by the start function block can be controlled by performing step SS11 and step SS12.

[0074] Step SS11 includes: when the start function block receives a manual start signal or an automatic start signal from the DCS system, the first rounded rectangle outputs a first process identification signal and makes the path line function block connected to the first rounded rectangle enter the active state.

[0075] In this step, when the start function block receives a manual start signal or an automatic start signal, both the first rounded rectangle and the path line function block connected thereto will output a first process identification signal, thereby indicating that the procedure can be considered to have started execution and the subsequent steps will be executed successively.

[0076] It should be noted that when a nuclear power unit triggers a certain protection action, the corresponding protection procedure needs to be executed. At this time, the DCS system issues a corresponding automatic start signal to the start function block, thereby realizing the automatic activation of the start function block. Further, since the nuclear power unit may not be able to trigger a certain protection action normally or some special working conditions lead to the need for corresponding protection to be put into operation, at this time, the staff can input a manual start signal by operating the man-machine interaction device.

[0077] Step SS12 includes: when the start function block does not receive an automatic start signal and a manual start signal, the first rounded rectangle outputs a second process identification signal and makes the path line function block connected to the start function block enter the inactive state.

[0078] In this step, when the start function block does not receive the automatic start signal and the manual start signal, both the first rounded rectangle and the path line function block connected to it will output the second process identification signal to indicate that the procedure has not started.

[0079] In one embodiment, as Figure 3 shown, the icon of the end function block may include a second rounded rectangle, and the second rounded rectangle includes an input port for connecting to the path line function block. Accordingly, the process identification signal output by the end function block can be controlled by performing step SS21 and step SS22.

[0080] Step SS21 includes: when the path line function block connected to the second rounded rectangle is in the active state or the end function block receives the manual end signal, the second rounded rectangle outputs the first process identification signal.

[0081] In this step, when the path line function block connected to the second rounded rectangle is in the active state or the end function block receives the manual end signal, both the second rounded rectangle and the path line function block connected to it will output the first process identification signal to indicate that the procedure has ended.

[0082] Step SS22 includes: when the path line function block connected to the first rounded rectangle is in the non - active state or the end function block does not receive the manual end signal, the second rounded rectangle outputs the second process identification signal.

[0083] In this step, when the path line function block connected to the first rounded rectangle is in the non - active state or the end function block does not receive the manual end signal, both the second rounded rectangle and the path line function block connected to it will output the second process identification signal to indicate that the procedure has not ended.

[0084] In one embodiment, as Figure 3 shown, the icon of the instruction text function block may include a first rectangle, and the first rectangle includes an input port and an output port for connecting to the path line function block. Accordingly, the process identification signal output by the instruction text function block can be controlled by performing step SS31 to step SS33.

[0085] Step SS31 includes: when the path line function block connected to the input port of the first rectangle is in the non - active state and does not receive the manual execution signal, the first rectangle outputs the second process identification signal.

[0086] In this step, the first rectangle outputting the second process identification signal can indicate that the instruction text function block is not activated (i.e., in the unexecuted state).

[0087] Step SS32 includes: when the path line function block connected to the first rectangular input port is in an active state and no manual execution signal is received, the instruction text function block determines whether the corresponding execution success signal is obtained from the DCS system based on its text interpretation. When the instruction text function block fails to obtain the corresponding execution success signal, the first rectangle outputs a third process identification signal. When the instruction text function block obtains the corresponding execution success signal, the first rectangle outputs a first process identification signal, causing the path line function block connected to the first rectangular output port to enter an active state.

[0088] In this step, when the path line function block connected to the first rectangular input port is in an active state and no manual execution signal is received, the instruction text function block is automatically activated. Then, based on the text interpretation of the instruction text function block, it determines whether the corresponding execution success signal is obtained from the DCS system. Exemplarily, if the text information of the instruction text function block is "close valve X", after the instruction text function block is activated, it can determine from the text information that the information to be obtained from the DCS system is the valve state of valve X. Therefore, it requests the DCS system to obtain the valve state and determines whether the valve state is closed. If it is closed, it is determined that the corresponding execution success signal is obtained, and then the first rectangle outputs a third process identification signal to indicate that the instruction text function block has successfully executed the logic function after automatic activation. On the contrary, if the valve state of valve X is not closed, the first rectangle outputs a first process identification signal to indicate that the instruction text function block has failed to execute the logic function after automatic activation.

[0089] Step SS33 includes: when the instruction text function block receives a manual execution signal, the first rectangle outputs a fourth process identification signal and causes the path line function block connected to the output port of the first rectangle to enter an active state.

[0090] It should be noted that due to abnormal operation of some devices in the DCS system or abnormal feedback signals (including the state information of devices such as valves) caused by abnormal operation of nuclear power unit equipment, it may result in the failure of the instruction text function block to execute the logic function successfully after automatic activation. After such a situation occurs, usually, the staff needs to go to the site to confirm the situation, such as determining the actual state of the device. For example, valve X has been normally closed, but its valve state feedback signal is abnormal, which causes the first rectangle to output a third process identification signal. Of course, it may also be that valve X fails to close normally due to other reasons (such as power failure, equipment failure, etc.). At this time, the staff needs to handle the abnormality immediately. After determining that valve X has been normally closed, the staff can input a manual execution signal through the operation of the man-machine interaction device, so that the first rectangle outputs a fourth process identification signal and the corresponding path line function block outputs a first process identification signal, thereby indicating that the instruction text function block has successfully executed the logic function after manual activation.

[0091] In one embodiment, as Figure 3 shown, the icon of the criterion function block may include a second rounded rectangle and two second rectangles connected to the second rounded rectangle. The second rounded rectangle includes an input port for connecting to the path line function block, and each second rectangle includes an output port for connecting to the path line function block. Accordingly, the process identification signal output by the criterion function block can be controlled by performing step SS41 to step SS33.

[0092] Step SS41 includes: when the path line function block connected to the input port of the second rounded rectangle is in an inactive state and the criterion function block does not receive a manual judgment signal, the second rounded rectangle outputs a second process identification signal.

[0093] In this step, the second rounded rectangle outputting the second process identification signal can indicate that the criterion function block is not activated (i.e., in an unexecuted state).

[0094] Step SS42 includes: when the path line function block connected to the input port of the second rounded rectangle is in an active state and the criterion function block does not receive a manual judgment signal, the second rounded rectangle outputs a first process identification signal, and the criterion function block obtains the operating parameters from the DCS system according to its text interpretation, and performs a judgment based on the operating parameters (including the working temperature, working pressure, working current, working voltage, various protection thresholds, etc. of the nuclear power plant equipment) and its text interpretation. According to the judgment result, it controls one of the second rectangles to output a first process identification signal, and makes the path line function block connected to the second rectangle outputting a process identification signal enter an active state.

[0095] In this step, when the path line function block connected to the second rounded rectangle input port is active and the criterion function block has not received a manual judgment signal, the criterion function block is automatically activated to obtain the operating parameters from the DCS system based on its text interpretation, execute the text judgment logic of the criterion function block according to the operating parameters, and finally control one of the second rectangles to output the first process identification signal according to the judgment result. Exemplarily, the text information of the criterion function block is "judge whether the Y temperature is less than the Z temperature threshold". After the criterion function block is activated, the criterion function block first determines, according to the text information, that the operating parameters to be obtained include the Y temperature and the Z temperature threshold. Therefore, it will request the DCS system to obtain the Y temperature and the Z temperature threshold, and then judge whether the Y temperature is less than the Z temperature threshold. If so, it controls the second rectangle (denoted as the yes result rectangle) corresponding to the subsequent procedure of "Y temperature is less than the Z temperature threshold" to output the first process identification signal, and makes the path line function block connected to the yes result rectangle output the first process identification signal to show that the subsequent execution path of the criterion function block after automatic activation is the subsequent procedure function block connected to the yes result rectangle; similarly, if the Y temperature is not less than the Z temperature threshold, it controls the second rectangle (denoted as the no result rectangle) corresponding to the subsequent procedure of "Y temperature is not less than the Z temperature threshold" to output the first process identification signal, and controls the path line function block connected to the no result rectangle to output the first process identification signal to show that the subsequent execution path of the criterion function block after automatic activation is the subsequent procedure function block connected to the no result rectangle.

[0096] Step SS43 includes: when the criterion function block receives a manual judgment signal, it outputs a four-process identification signal, controls one of the second rectangles to output a process identification signal according to the manual judgment signal, and makes the path line function block connected to the second rectangle that outputs the process identification signal enter the active state.

[0097] Due to the existence of operating parameter errors, parameter error risks, and the fact that the nuclear power unit may be in a special working condition, the path executed by the criterion function block after automatic activation may not necessarily meet the actual requirements. The purpose of this step is to enable the staff to input a manual judgment signal to the criterion function block by operating the man-machine interaction device, so as to customize the control of the yes result rectangle or the no result rectangle to output the first process identification signal.

[0098] In one embodiment, as Figure 3 shown, the icon of the parameter graph function block may include a third rectangle and a plurality of parameter interval graphs provided in the third rectangle. The third rectangle includes an input port for connecting to the path line function block, and each parameter interval graph includes an output port for connecting to the path line function block. Correspondingly, the process identification signal output by the criterion function block can be controlled by executing step SS51 to step SS53.

[0099] Step SS51 includes: when the path line function block connected to the third rectangular input port is in an inactive state and the parameter diagram function block has not received a manual selection signal, the third rectangle outputs a second process identification signal.

[0100] In this step, the third rectangle outputting the second process identification signal can indicate that the parameter diagram function block is not activated (i.e., in an unexecuted state).

[0101] Step SS52 includes: when the path line function block connected to the third rectangular input port is in an active state and the parameter diagram function block has not received a manual selection signal, the third rectangle outputs a first process identification signal, obtains operating parameters from the DCS system according to its text interpretation, performs parameter range recommendation based on the operating parameters and their text interpretation, and controls the path line function block connected to one of the parameter range diagrams to enter an active state according to the recommendation result.

[0102] In this step, when the path line function block connected to the third rectangular input port is in an active state and the parameter diagram function block has not received a manual selection signal, the parameter diagram function block is automatically activated to obtain operating parameters from the DCS system according to its text interpretation, then executes the text recommendation logic of the parameter diagram function block according to the operating parameters, and finally controls the path line function block connected to one of the parameter range diagrams to enter an active state (i.e., outputs a first process identification signal) according to the recommendation result to show the subsequent execution path corresponding to the parameter diagram function block after automatic activation. Exemplarily, the text information of the parameter diagram function block is "determine which of the A pressure range, B pressure range, and C pressure range the primary loop pressure is in". After the parameter diagram function block is activated, the parameter diagram function block first obtains the primary loop pressure, A pressure range, B pressure range, and C pressure range according to its text information, then determines which pressure range the primary loop pressure is in, records the determined range as the recommended range, and finally controls the path line function block connected to the recommended range to enter an active state to show that the subsequent execution path recommended by the parameter diagram function block after automatic activation is the subsequent procedure function block connected to the recommended range.

[0103] To improve the convenience of display, the parameter range diagram is preferably set to an image capable of displaying corresponding parameter range information. For example, if the A pressure range is from L to M, then "L to M" can be directly displayed within the parameter range diagram.

[0104] Step SS53 includes: when the parameter diagram function block receives a manual selection signal, the third rectangle outputs a fourth process identification signal and controls the path line function block connected to one of the parameter range diagrams to enter an active state according to the manual selection signal.

[0105] In one embodiment, as Figure 3As shown, the icon of the jump link function block may include a pentagon, and the pentagon includes an input port for connecting to the path line function block. Accordingly, the process identification signal output by the jump link function block can be controlled by performing the following steps: when the path line function block connected to the pentagon input port is in an active state, determine whether a manual jump signal is received. If a manual jump signal is received, the jump link function block outputs a first process identification signal; if a manual jump signal is not received, the jump link function block outputs a second process identification signal.

[0106] In this step, since the jump function generally belongs to an active operation function, the first process identification signal will be output only after the path line function connected to the pentagon input port is activated and a manual jump signal is received, indicating that the jump operation has been performed.

[0107] In this step, the staff can operate the human-computer interaction device to input a manual selection signal to the parameter graph function block, so as to customize and control which one of the multiple parameter interval graphs is the recommended interval.

[0108] In this embodiment, the graphical shape of the parameter interval graph can refer to Figure 3 , and of course it can also be other graphics, such as rectangles, etc., which are not specifically limited here.

[0109] In one embodiment, the process identification signal is set to a signal capable of controlling the border color and / or background filling color of the corresponding icon in the procedure function block, and the border colors and background filling colors controlled by the process identification signals with different serial numbers are different from each other. Specifically, the first process identification signal is set to control the border color of the corresponding procedure function block to be set to green and / or the background filling color to be set to gray; the second process identification signal is set to control the border color of the corresponding procedure function block to be set to gray and / or the background filling color to be set to white; the third process identification signal is set to control the border color of the corresponding procedure function block to be set to blue and / or the background filling color to be set to white; the fourth process identification signal is set to control the border color of the corresponding procedure function block to be set to blue and / or the background filling color to be set to gray.

[0110] In another embodiment, the process identification signal can also be a symbol for adding a prompt identification to the corresponding procedure function block, such as a check mark (e.g., "√") and a cross mark (e.g., "×"). Specifically, when a certain procedure function block is activated, a check mark can be added near it as the first process identification signal, the third process identification signal or the fourth process identification signal; when a certain procedure function block is not activated, a cross mark can be added near it as the second process identification signal.

[0111] In one embodiment, the human-machine interaction device may include a mouse. Correspondingly, the nuclear power plant digital procedure display method may further include: operating the icons of each procedure function block through the human-machine interaction device to input a manual operation signal. Specifically, the staff can click, select, etc. the icons in the procedure function block by operating the human-machine interaction device, so as to input the corresponding manual operation signal. For example, a manual start signal or a manual end signal can be input by clicking the first rounded rectangle or the second rounded rectangle; a manual execution signal can be input by clicking the first rectangle; a manual judgment signal can be input by clicking the second rectangle of the criterion function block. Further, one of the second rectangles can be clicked to select the subsequent procedure function block connected to the clicked second rectangle as the subsequent execution path; a manual selection signal can be input by clicking the parameter interval graph. Further, one of the parameter interval graphs can be clicked to select the subsequent procedure function block connected to the clicked parameter interval graph as the subsequent execution path; a manual jump signal can be input by clicking the pentagon. Of course, the manual operation signal can also be input by operating the touch screen, operating the keyboard, or voice input method.

[0112] Step S4 includes: establishing communication with the display terminal and transmitting the basic procedure file to the display terminal in real time. In this step, the display terminal can be an existing display that can display the changes of the basic procedure file in real time.

[0113] In one embodiment, the nuclear power plant digital procedure display method may further include: judging whether the basic procedure file has been executed completely; when the basic procedure file has been executed completely, determining the executed basic procedure file as the procedure execution file; judging whether a recording signal has been obtained; when the recording signal has been obtained, recording the procedure execution file. Specifically, when the end function block is activated (i.e., the first process identification signal is output), it can be determined that the basic procedure file has been executed completely; and recording the procedure execution file is to archive it as an electronic archive file so that the staff can check the procedure execution process, including checking the execution status (executed in the automatic activation state or the manual activation state) of each procedure function block, the specific execution time, etc. In addition, the staff can input the recording signal by operating the human-machine interaction device.

[0114] In one embodiment, the nuclear power plant digital procedure display method may further include: obtaining an editing signal; editing the procedure function blocks in the basic procedure file or the procedure execution file according to the editing signal to generate a new basic procedure file. Wherein, the procedure execution file may be a recorded or unrecorded procedure execution file. In this embodiment, the staff can input the editing signal by operating the man-machine interaction device. Understandably, the function of this embodiment is to enable the staff to automatically edit the basic procedure file or the procedure execution file according to actual needs to obtain a new basic procedure file, so as to realize the rapid maintenance and upgrade of the digital procedure, improve the editing flexibility and establishment efficiency of the basic procedure file, and help reduce the workload of the operator.

[0115] Understandably, the technical solution of the present invention realizes the digital display of the operation procedure, and also realizes functions such as the execution status monitoring of the procedure steps, the automatic guidance of the procedure path, and the status change / deviation reminder, improving the automation and intelligence level of the operation procedure, and playing a positive role in improving the procedure execution efficiency, reducing the workload of the operator, reducing the risk of human error, and improving the safety of the nuclear power plant.
