[0046] The execution subject of the digital instrumentation and control system screen conversion method provided in the embodiment of the present application may include but is not limited to electronic devices such as mobile phones, tablet computers, laptop computers and desktop computers.

[0047] The digital instrumentation and control system screen conversion method provided in the embodiment of the present application can be applied to convert the DCS screen in the field unit of a nuclear power plant into the DCS screen of the auxiliary system in the nuclear power plant. Specifically, the user can perform each step of the digital instrumentation and control system screen conversion method provided in the embodiment of the present application through an electronic device, so that the DCS screen in the field unit of the nuclear power plant can be automatically converted into the DCS screen of the auxiliary system in the nuclear power plant through the electronic device.

[0048] See also Figure 1 , Figure 1 The following is a flowchart of a method for converting a screen of a digital instrumentation and control system provided in an embodiment of the present application. The method for converting a screen of a digital instrumentation and control system provided in an embodiment of the present application may include steps S101 to S106, which are described in detail as follows:

[0049] In S101, first information of each first signal point and second information of each first intermediate variable point on an initial screen of a digital instrumentation and control system are obtained.

[0050] In the embodiment of the present application, the electronic device first needs to obtain the first information of each first signal point and the second information of each first intermediate variable point on the initial screen of the digital instrumentation and control system.

[0051] The initial screen of the digital instrumentation and control system refers to the DCS screen in the on-site unit in the nuclear power plant. The DCS screen in the on-site unit in the nuclear power plant may include the status of each device and system in the nuclear power plant.

[0052] The number of initial pictures may be several, and each initial picture may include several first signal points and several first intermediate variable points.

[0053] In a possible implementation, the first information of each first signal point and the second information of each first intermediate variable point on the initial picture may be obtained through steps a and b, as described in detail as follows:

[0054] In step a, for each first signal point on each initial screen, the screen name information, icon number information, signal reference information, icon type information and data type information of the first signal point are obtained as the first information.

[0055] In this implementation, the electronic device can obtain the screen name information, icon number information, signal reference information, icon type information and data type information of each first signal point on each initial screen as the first information.

[0056] In step b, for each first intermediate variable point on each initial screen, the screen name information, icon number information, signal reference information, icon type information and data type information of the first intermediate variable point are obtained as the second information.

[0057] In this implementation, the electronic device can obtain the screen name information, icon number information, signal reference information, icon type information and data type information of each first intermediate variable point on each initial screen as the second information.

[0058] In practical applications, the specific method for distinguishing and determining the first signal point and the intermediate variable point can be set according to actual needs and is not limited here.

[0059] In one possible implementation, after the electronic device obtains the first information of each first signal point and the second information of each first intermediate variable point on the initial screen of the digital instrumentation and control system, it can sort the first information and the second information according to the screen name information and icon number information of each first signal point, as well as the screen name information and icon number information of each first intermediate variable point.

[0060] Among them, the picture name information of the first signal point is used to describe the picture name of the initial picture corresponding to the first signal point, the icon number information of the first signal point is used to describe the icon number of the first signal point, the picture name information of the first intermediate variable point is used to describe the picture name of the initial picture corresponding to the first intermediate variable point, and the icon number information of the first intermediate variable point is used to describe the icon number of the first intermediate variable point.

[0061] Specifically, the electronic device may first perform a first priority sorting on each first information and each second information according to the picture name information of each first signal point and the picture name information of each first intermediate variable point. After completing the first priority sorting, the electronic device may perform a second priority sorting on each first information and each second information according to the symbol number information of each first signal point and the symbol number information of each first intermediate variable point.

[0062] In the embodiment of the present application, the purpose of sorting the first information and the second information is to ensure that the second intermediate variable points obtained by subsequent screen configuration logic translation and conversion will not have a disordered correspondence with the target logical expression.

[0063] In S102, second signal points that need to be locally calculated are determined among the first signal points.

[0064] In the embodiment of the present application, after acquiring the first information of each first signal point on the initial screen of the digital instrumentation and control system, the electronic device may determine the second signal point that needs to be locally calculated among the first signal points.

[0065] The need to perform local calculations refers to the need to perform calculations on a control device corresponding to an initial screen of the digital instrumentation and control system.

[0066] In a possible implementation manner, the electronic device may determine each second signal point according to the signal reference information and the icon type information of each first signal point.

[0067] The signal reference information of the first signal point is used to describe the signal reference relationship of the first signal point, and the icon type information to which the first signal point belongs is used to describe the type of the icon to which the first signal point belongs.

[0068] In S103, the third information of each second signal point is converted into the fourth information of the second intermediate variable point.

[0069] In an embodiment of the present application, after determining the second signal point that needs to be locally calculated among each first signal point, the electronic device can convert the third information of each second signal point into the fourth information of the second intermediate variable point to complete the creation of a new intermediate variable point.

[0070] Specifically, the electronic device may convert the screen name information, icon number information and data type information of each second signal point into the fourth information of the second intermediate variable point according to a preset conversion algorithm.

[0071] In the embodiment of the present application, the fourth information of the second intermediate variable point may be the name of the second intermediate variable point.

[0072] The beneficial effect of the step of converting the third information of each second signal point into the fourth information of the second intermediate variable point is that in the prior art, the relevant points displayed on the DCS screen of the auxiliary system need to be first locally calculated in the device corresponding to the DCS screen in the field unit, and after the calculation is completed, the device corresponding to the DCS screen in the field unit sends the calculation result to the device corresponding to the DCS screen of the auxiliary system for display. However, through this step, the variables that need to be locally calculated can be converted into intermediate variables stored in the database, and the logical relationship is guaranteed to remain unchanged during the conversion process, so that a large number of variables that need to be locally calculated can be compressed into a small number of intermediate variables stored in the database, thereby improving the efficiency of obtaining the variable, and then improving the screen conversion efficiency of the DCS.

[0073] In S104, the target configuration logic expression corresponding to each first intermediate variable point is determined respectively according to the second information.

[0074] In the embodiment of the present application, after converting the third information of each second signal point into the fourth information of the second intermediate variable point, the electronic device can determine the target configuration logic expression corresponding to each first intermediate variable point respectively according to the second information.

[0075] The step of respectively determining the target configuration logic expression corresponding to each first intermediate variable point according to the second information is also the step of logical translation of the screen configuration.

[0076] In one possible implementation, the electronic device can determine, for each first intermediate variable point, the target configuration logic expression corresponding to the first intermediate variable point based on the second information of the first intermediate variable point, the initial configuration logic expression corresponding to the first intermediate variable point, and the fifth information of the logic-related point of the first intermediate variable point, thereby being able to obtain the target configuration logic expression corresponding to each first intermediate variable point.

[0077] The following provides an example to illustrate how to configure a target logic expression corresponding to a first intermediate variable point.

[0078] Taking a first intermediate variable point for high power alarm in a screen named "ARE432KM" as an example, the configuration logic of the first intermediate variable point is that when the power detected by the power detector numbered "3ARE401KS / XH01" is greater than the preset threshold, the corresponding position on the "ARE432KM" screen will display an alarm signal of a preset color.

[0079] First, you need to identify each configuration input point, and then determine the relationship between each signal point.

[0080] Specifically, the screen configuration logic related point information corresponding to the first intermediate variable point can be obtained first. Figure 2 , Figure 2 A schematic diagram of a screen configuration logic related point information provided by an embodiment of the present application. Figure 2 In the table, the P1 column indicates the screen name where the logically related point is located, the Ty column indicates the type of operation performed by the logically related point, Seq indicates the icon number of the operation type, and Subva indicates the logically related point information for the Ty column operation (including the point name in the database, the point name for the local operation, the text content displayed after the conditions are met, etc.). Figure 2 Taking the first line in as an example, the logic related point is the MELD_8PM operation on the 3ARE004YFU screen. The symbol number of the MELD_8PM operation is 033.1, and the signal received by the point is 3ARE 401KS___XH01YP01.

[0081] After that, you can get the configuration input points corresponding to the MELD_8PM operation. Figure 3 , Figure 3 A schematic diagram of a configuration input point provided in an embodiment of the present application. Figure 3 As shown, the MELD_8PM operation has two input points, one is 3ARE401KS / XH01 (a point existing in the database), and the other is the local variable point obtained after the "&" operation.

[0082] You can then obtain the configuration properties of the MELD_8PM operation. Figure 4 , Figure 4 A schematic diagram of a configuration attribute provided in an embodiment of the present application. Figure 4 Configure the properties of the MELD_8PM logic operation (033.1) according to Figure 4 It can be seen that for the points existing in the database, Que: P Point-ID is followed by the value 3ARE 401KS___XH01YP01, but Que: L LocVar is empty; and for the points using local calculations, Que: P Point-ID is empty, and Que: L LocVar has the value 033.2__.BIN, which means that the local variable uses the result (output) of the (033.2) configuration calculation as one of the inputs of the (033.1) configuration.

[0083] Then, the corresponding position of the configuration input point corresponding to the MELD_8PM operation in the database can be obtained. In the embodiment of the present application, the corresponding position of the configuration input point corresponding to the MELD_8PM operation in the database can be directly obtained from the point table database (that is, the database composed of the second information of each first intermediate variable point and the fourth information of each second intermediate variable point stored in the electronic device).

[0084] Since the data used in the target configuration logic expression must be in the point table database, it is necessary to determine the local variables that do not meet the above requirements. If one of the two inputs of the configuration operation 033.2 is a point in the point table database, and the other is a local variable input, then the relationship between the two input points and the 033.2___.BIN intermediate variable is obtained, that is, 3ARE 401KS______XH01YP01 and 033.3___.BIN are used to perform the configuration 033.2 operation to obtain 033.2___.BIN.

[0085] It can be seen that by processing the point table database through the screen configuration logic translation algorithm, the relationship between the input variables of each screen configuration can be identified.

[0086] After identifying the various configuration input points and then determining the relationship between the various signal points, logical calculations can be performed.

[0087] Continuing to take the first intermediate variable point for high power alarm in the screen named "ARE432KM" as an example, the logic operation rule of MELD_8PM is that when there is an input signal from the top of the configuration, there will be a corresponding display below. For example, when the signal generated by 3ARE 401KS / XH01 is sent to the "1" input port of MELD_8PM, the "H1" below it will change from hidden to displayed in the DCS screen, thereby realizing the high power alarm function of H1 on the DCS screen of 3ARE 401KS / XH01. The entire logic of this configuration can be expressed by the following expression:

[0088] 1*ARE 401KS / XH01+(-1)*033.2___.BIN(1)

[0089] When the expression evaluates to 1, H1 with a green background (high 1 alarm) is displayed. When the expression evaluates to -1, L1 with a green background (low 1 alarm) is displayed. When the expression evaluates to 0, no alarm is displayed on the screen.

[0090] 033.2___.BIN is the output of 033.2 configuration. From the point table database, we can know that 033.2 configuration performs "Logic_AND" operation. Therefore, the expression of 033.2___.BIN is as follows:

[0091] 033.2___.BIN=3ARE 401KS / XH01YP01&&033.3___.BIN

[0092] The same applies to 033.3___.BIN.

[0093] Finally, formula (1) can be transformed into the following formula:

[0094] 1*ARE 401KS / XH01+(-1)*

[0095] (3ARE 401KS / XH01YP01&&(not(ARE401KS / XH01YP01))) (2)

[0096] If only the screen configuration logic translation and calculation are performed, then formula (2) is the final expression used for screen dynamic calculation. If complex logic is encountered, calculation cannot be performed on the screen. However, if the logic point conversion is performed, the local variable of 033.2___.BIN will be converted to ARE0058L / XB88. Accordingly, formula (1) can be converted into the following formula:

[0097] 1*ARE 401KS / XH01+(-1)*ARE0058L / XB88

[0098] In this way, even very complex dynamic logic can be implemented on the DCS screen of the auxiliary system in the nuclear power plant.

[0099] After the auxiliary system in the nuclear power plant collects the DCS data into the database, it uses the logic formula obtained in the above example to calculate in the point table database, and then sends the result to the DCS screen of the auxiliary system in the nuclear power plant. Compared with the data transmission of the original screen, in addition to the logic becoming simpler, the variables of the local operation can also be stored in the database as intermediate variables for query and copying, which provides convenience for subsequent screen verification.

[0100] In S105, the target configuration logic expression corresponding to each second intermediate variable point is determined respectively according to the fourth information.

[0101] In the embodiment of the present application, in addition to determining the target configuration logic expression of each first intermediate variable point according to the second information, the electronic device can also determine the target configuration logic expression corresponding to each second intermediate variable point according to the fourth information.

[0102] The specific implementation method of the electronic device determining the target configuration logic expression corresponding to each second intermediate variable point according to the fourth information can be involved in the corresponding description of S105, which will not be repeated here.

[0103] In S106, the initial screen is converted into the target screen according to the target configuration logic expression corresponding to each first intermediate variable point and the target configuration logic expression corresponding to each second intermediate variable point.

[0104] In an embodiment of the present application, after obtaining the target configuration logic expression corresponding to each first intermediate variable point and the target configuration logic expression corresponding to each second intermediate variable point, the electronic device can convert the initial screen into the target screen according to the target configuration logic expression corresponding to each first intermediate variable point and the target configuration logic expression corresponding to each second intermediate variable point.

[0105] After converting the initial screen to the target screen, the electronic device can also perform consistency check on the initial screen and the target screen. Specifically, historical data can be used to drive the unit DCS to operate under steady-state or transient conditions, and data can be obtained from the XU (a server) in real time, and sent to a special database for processing, and the processed values ​​can be sent to the auxiliary system for display. In theory, the unit DCS and the auxiliary system are driven by the same data, eliminating the interference of inconsistent screens caused by inconsistent time or inconsistent data. Therefore, whether it is a static screen or a dynamic screen, as long as there is an inconsistency, it means that the auxiliary system and the unit screen are actually inconsistent, and further modification is required.

[0106] It can be seen from the above that in the digital instrumentation and control system screen conversion method provided in the embodiment of the present application, the electronic device first obtains the first information of the first signal point of the initial screen and the second information of the first intermediate variable point, then determines the second signal point in the first signal point that needs to be locally calculated, and then converts the third information of the second signal point into the fourth information of the second intermediate variable point, and then determines the target configuration logic expression of each first intermediate variable point according to the second information, and then determines the target configuration logic expression of each second intermediate variable point according to the fourth information, and finally converts the initial screen into the target screen according to the target configuration logic expression of each first intermediate variable point and the target configuration logic expression of each second intermediate variable point. Since the execution subject of each step provided by the present method is an electronic device, the screen conversion of DCS can be realized by the electronic device, which improves the efficiency of DCS screen conversion.
