[0002] In related technologies, the basic form of input-operation logic-output is generally adopted by DCS (Distributed Control System) software to complete control functions, and the operation logic part is formed by combining multiple function blocks to form a controller.

Although this method has high processing efficiency, when the function block names in the operation logic configuration of different DCS are inconsistent, or the page numbers or page names of the logic blocks are different, it will lead to matching failure.

[0030] Please refer to Figure 1 , Figure 1 is a schematic diagram of a comparison method for a controller control logic function provided by an embodiment of the present application. As shown in Figure 1 , the method can include but is not limited to the following steps:

[0031] Step S101: Obtain the output function block of each controller in the plurality of controllers and the identification information corresponding to the output function block.

[0032] In the embodiments of the present application, the plurality of controllers described above can be two controllers.

[0033] For example, the output function block of each controller in the plurality of controllers to be compared in the control logic is acquired, and the identification information corresponding to each output function block is acquired.

[0034] In the embodiments of the present application, the identification information corresponding to each output function block can be an output point name corresponding to each output function block. The output function block includes at least one of a switching value output function block, an analog output function block, a structure output function block, and a network intermediate point output function block.

[0035] In step S102, a feature value of the output function block is generated based on the identification information corresponding to the output function block.

[0036] For example, the identification information corresponding to each output function block is taken as the feature value corresponding to the output function block.

[0037] In step S103, a superior function block of the output function block is acquired, and a feature value of the superior function block is generated based on the feature value of the output function block.

[0038] In the embodiments of the present application, the superior function block of the output function block is a function block located upstream of the output function block.

[0039] For example, the superior function block located upstream of the output function block in the operation logic configuration is acquired, and the feature value of the superior function block corresponding to the output function block is set based on the feature value of the output function block.

[0040] In step S104, the control logic of the plurality of controllers is compared based on the feature values of the function blocks in each controller, and a comparison result of the control logic of the plurality of controllers is acquired.

[0041] For example, the function blocks with the same or similar operation logic in the function blocks in the plurality of controllers are acquired based on the feature values of the function blocks in each controller, and the function blocks with the same or similar operation logic are compared to compare the control logic of the plurality of controllers, and a comparison result of the control logic of the plurality of controllers is acquired.

[0042] By implementing the embodiments of the present application, the superior function block of the output function block in each controller in the plurality of controllers can be acquired based on the output function block, and the feature value of the superior function block is generated based on the feature value of the output function block, so that the control logic of the plurality of controllers is compared based on the feature values of the function blocks in the controller. The control logic functions of different controllers can be quickly and accurately compared.

[0043] Please refer to Figure 2 , Figure 2A schematic diagram of an acquisition process of a superior function block is provided in the embodiments of the present application. It can be understood that the following method can be used to acquire the corresponding superior function block for each output function block in each controller. As shown in Figure 2 The method can include, but is not limited to, the following steps:

[0044] Step S201: Acquire the first input pin of the output function block and the corresponding first connection information.

[0045] For example, acquire all the input pins to which the output function block belongs as the first input pin, and acquire the first connection information corresponding to the first input pin.

[0046] Step S202: Determine the first target pin connected with the first function block from the first input pin based on the first connection information.

[0047] For example, based on the first connection information, determine whether the first input pin is connected with other function blocks, determine the first input pin connected with other function blocks as the first target pin, and determine the function block connected with the first target pin as the first function block.

[0048] It can be understood that in the embodiments of the present application, the first target pin can be one or more, and the number of the first function blocks is the same as the number of the first pins.

[0049] Step S203: Determine the first function block as the superior function block, and generate the characteristic value of the first function block based on the identification information of the first target pin and the characteristic value of the output function block.

[0050] For example, determine the first function block as the superior function block, and take the identification information of the first target pin and the characteristic value of the output function block as the characteristic value of the first function block.

[0051] In the embodiments of the present application, the identification information of the first target pin can be the pin number of the first target pin.

[0052] Step S204: Acquire the second input pin of the superior function block and the corresponding second connection information.

[0053] For example, acquire the input pin to which each superior function block belongs as the second input pin, and acquire the second connection information corresponding to the second input pin.

[0054] Step S205: If the second target pin connected with the second function block exists in the second input pin, determine whether the second function block has been determined as the superior function block; if the second target pin connected with the second function block does not exist in the second input pin, exit the process.

[0055] As an example, it is determined whether the second input pin to which each upper function block belongs is connected with a second function block based on the second connection information of the second input pin to which each upper function block belongs, respectively, and if the second input pin is connected with a second function block, it is determined whether the second function block has been determined as an upper function block.

[0056] As another example, it is determined whether the second input pin to which each upper function block belongs is connected with a second function block based on the second connection information, and if the second input pin to which an upper function block belongs is not connected with a second function block, it is determined that the upper function block has no new upper function block, and the upper function block obtaining process of the branch of the upper function block is exited.

[0057] It can be understood that each time a new upper function block is determined, the new upper function block and the corresponding lower function block can be taken as a new branch, and it can be determined for each branch whether the branch has a new upper function block, and if the branch has no new upper function block, it can be determined that all upper function blocks of the branch have been determined.

[0058] Step S206: If the second function block is not determined as an upper function block, a characteristic value of the second function block is generated based on the identification information of the second target pin and the characteristic value of the upper function block, and the second function block is determined as a new upper function block; if the second function block has been determined as an upper function block, the process is exited.

[0059] As an example, if there is a second function block that has not been determined as an upper function block, a characteristic value of the second function block is generated based on the identification information of the second target pin and the characteristic value of the upper function block, and the second function block is determined as a new upper function block.

[0060] As another example, if the second function block has been determined as an upper function block through the completed process, it is determined that the upper function block has no new upper function block, and the upper function block obtaining process of the branch corresponding to the upper function block is exited.

[0061] In the embodiments of the present application, the identification information of the second target pin can be a pin number of the second target pin.

[0062] It can be understood that each time a second function block is determined, it can be determined whether the second function block has been determined as an upper function block in other branches of the upper function block obtaining process corresponding to the input function block, or has been determined as an upper function block in the upper function block obtaining process corresponding to other output function blocks of the same controller.

[0063] Step S207: Return to execute step S204.

[0064] For example, the second function block is taken as a new first function block, and the execution step S4 is returned until all the parent function blocks of all branches corresponding to the output function block are determined, and the parent function block acquisition process of the output function block is exited. The above process is executed based on another output function block which has not executed the parent function block acquisition process.

[0065] By implementing the embodiment of the application, the output function block is taken as a basis for recursive query, so that the feature values corresponding to the function blocks in the controller are set, and the control logic of different controllers is compared based on the feature values.

[0066] Please refer to Figure 3 , Figure 3 is a schematic diagram of a parent function block acquisition scheme provided by the embodiment of the application, as shown in Figure 3 , first, all the output function blocks in the controller are retrieved and acquired, and the feature values of the output function blocks are recorded as BlkOut[i], and BlkOut[i] is the output point name corresponding to each output function block; then, all the parent function blocks of the output function blocks are found through the connection line or intermediate transmission, and the feature values of the parent function blocks of the output function blocks are recorded as BlkOut[i]_In[j], and In[j] is the pin number of the pin connected to the parent function block in the output function block; then, the parent function blocks are continuously found upwards, and the feature values of the new parent function blocks found are recorded as BlkOut[i]_In[j]_In[k], and In[k] is the pin number of the pin connected to the new parent function block in the original parent function block. At the same time, the recursive condition is judged in the finding process, that is, when there is no parent function block, or the new found function block has been marked as a parent function block, it is judged that all the parent function blocks of the output function block have been processed; then, the above steps are repeated until the feature value generation of all the function blocks in the controller is completed.

[0067] In an implementation mode, the function blocks with the same feature values in multiple controllers can be acquired, and the function blocks with the same feature values are compared to acquire the control logic comparison result of the multiple controllers. As an example, please refer to Figure 4 , Figure 4 is a schematic diagram of another control logic function comparison method provided by the embodiment of the application. As shown in Figure 4 , the method can include but is not limited to the following steps:

[0068] Step S401: acquiring the output function block of each controller in multiple controllers and the identification information corresponding to the output function block.

[0069] In the embodiments of the present application, step S401 can be implemented by any of the embodiments of the present application, and the embodiments of the present application do not limit this and will not be repeated here.

[0070] Step S402: generating a feature value of the output function block based on the identification information corresponding to the output function block.

[0071] In the embodiments of the present application, step S402 can be implemented by any of the embodiments of the present application, and the embodiments of the present application do not limit this and will not be repeated here.

[0072] Step S403: obtaining a superior function block of the output function block, and generating a feature value of the superior function block based on the feature value of the output function block.

[0073] In the embodiments of the present application, step S403 can be implemented by any of the embodiments of the present application, and the embodiments of the present application do not limit this and will not be repeated here.

[0074] Step S404: obtaining a first target function block of a first controller in the plurality of controllers.

[0075] For example, any one of the plurality of controllers is obtained as the first controller, and any one of the function blocks in the first controller is obtained as the first target function block.

[0076] Step S405: obtaining a second target function block of a second controller in the plurality of controllers based on the feature value of the first target function block.

[0077] For example, the second target function block in the second controller in the plurality of controllers is obtained based on the feature value of the first target function block.

[0078] In the embodiments of the present application, the second controller is other than the first controller in the plurality of controllers, and the feature value of the second target function block is the same as the feature value of the first target function block; or the similarity between the feature value of the second target function block and the feature value of the first target function block is greater than a preset similarity threshold.

[0079] Step S406: comparing the related information of the first target function block and the related information of the second target function block to obtain a comparison result.

[0080] In the embodiments of the present application, the above-mentioned related information includes the output value and / or the parameter value of the function block.

[0081] As an example, the output value of the first target function block and the output value of the second target function block are compared to obtain a comparison result.

[0082] As another example, the parameter value of the first target function block and the parameter value of the second target function block are compared to obtain a comparison result.

[0083] As yet another example, the output value of the first target function block and the output value of the second target function block are compared, and the parameter value of the first target function block and the parameter value of the second target function block are compared to obtain a comparison result.

[0084] Step S407: The above steps are repeated until all function blocks in the first controller are traversed, and a control logic comparison result of the plurality of controllers is obtained.

[0085] For example, another function block in the first controller which has not been compared is obtained, and the other function block is taken as a new first target function block to execute the above steps until all function blocks in the first controller are selected as the first target function block and the comparison steps are executed, and a control logic comparison result of the plurality of controllers is obtained based on the comparison result of each function block in the first controller.

[0086] By implementing the embodiments of the present application, the upper function block of the output function block can be obtained based on the output function block of each controller in the plurality of controllers, and the characteristic value of the upper function block is generated based on the characteristic value of the output function block, so that the function blocks with the same characteristic value in the plurality of controllers are obtained, and the function blocks with the same characteristic value are compared to obtain a control logic comparison result of the plurality of controllers. The control logic functions of different controllers can be quickly and accurately compared.

[0087] Please refer to Figure 5 , Figure 5 is a schematic diagram of a comparison method of a controller function block provided by an embodiment of the present application. As shown in Figure 5 , first, an arbitrary function block M[i] (i.e., the first target controller) is retrieved from the controller A (i.e., the first controller), and the characteristic value m of the function block M[i] is obtained; then, a function block N[j] with the same characteristic value m is obtained from the controller B, and the input value and the parameter value of the function block M[i] and the function block N[j] are compared, and the difference is recorded; then, the above steps are repeated until all function blocks in the controller A are traversed.

[0088] In some embodiments of the present application, the controller B can be a plurality of controllers, so that the function blocks with the same characteristic value m as the function block M[i] can be obtained from each controller B, and compared.

[0089] In some embodiments of the present application, the method further comprises: taking the output function block of each controller as an index entry, and taking the identification information corresponding to the output function block as an index value of the index entry, to generate an index table corresponding to each controller.

[0090] For example, taking the output function block of each controller as an index entry, and taking the identification information corresponding to the output function block as an index value of the index entry corresponding to the output function block, to generate an index table corresponding to each controller, so as to facilitate operation when the upper function block of the output function block is obtained, and the characteristic value of the upper function block is generated based on the characteristic value of the output function block.

[0092] In an implementation manner, the processing module 603 is specifically configured to: step S1: acquire a first input pin of the output function block and corresponding first connection information; step S2: determine a first target pin connected with a first function block from the first input pin based on the first connection information; step S3: determine the first function block as the upper function block, and generate a characteristic value of the first function block based on the identification information of the first target pin and the characteristic value of the output function block; step S4: acquire a second input pin of the upper function block and corresponding second connection information; if there is a second target pin connected with a second function block in the second input pin, determine whether the second function block has been determined as the upper function block; if there is no second target pin connected with a second function block in the second input pin, exit the flow; step S6: if the second function block has not been determined as the upper function block, generate a characteristic value of the second function block based on the identification information of the second target pin and the characteristic value of the upper function block, and determine the second function block as a new upper function block; if the second function block has been determined as the upper function block, exit the flow; and step S7: return to execute step S4.

[0093] In an implementation manner, the comparison module 604 is specifically configured to: acquire a first target function block of a first controller in the plurality of controllers; acquire a second target function block of a second controller in the plurality of controllers based on a characteristic value of the first target function block; compare related information of the first target function block and related information of the second target function block to obtain a comparison result; and repeat the above steps until all function blocks in the first controller are traversed to obtain a control logic comparison result of the plurality of controllers.

[0094] In an optional implementation manner, the related information includes an output value and / or a parameter value of the function block.

[0095] In an implementation manner, the generation module 601 is further configured to: take an output function block of each controller as an index entry, and take identification information corresponding to the output function block as an index value of the index entry to generate an index table corresponding to each controller.
