Description
Technical Field
The present application relates to the field of industrial digitizing technology, and more particularly, to a PMML file, and a method and apparatus for integrating a runtime environment and industrial software thereof, and an electronic device and a computer readable storage medium.
Background
As the degree of digitization and intellectualization of intelligent factories is higher, industrial algorithm integration and multiplexing are more and more important. On one hand, industrial algorithms have been widely accumulated in enterprises and institutions and scientific research institutes, and are basically developed and completed by mature business or open source software; on the other hand, the industrial system is basically standardized, the intelligent requirements are higher and higher, and the requirements on industrial algorithm integration are higher and higher.
Traditional data modeling and industrial software integration are generally performed in a customized manner. The first common scheme is that commercial data modeling software adopts a standard communication protocol to communicate when interfacing with an industrial control system, so that after modeling factory engineering input, output, configuration and monitoring point items are required to correspond to an information model of the communication protocol, the information model is also required to interface with a target field model. This approach employs custom development or manual-to-point to achieve semantic interoperability between software systems, resulting in an exponential increase in custom development costs when integrating multiple different business and industrial software, resulting in very inefficient system integration. A second common approach is for the individual data models to integrate the individual industrial software using OPC UA communication protocols and metamodel capabilities. However, in the scheme, the industrial field information model is unified by utilizing the OPC UA meta-model, but the corresponding mapping of the semantics is needed to be manually realized when different businesses develop software, so that the integration efficiency of realizing the software semantic interoperability is still low, and the risk of mistakes is faced. A third common approach is that individual data modeling software has basically supported exporting PMML software and parsing and integrating point-to-point implementations with existing software models in a unified runtime environment through PMML model expression capabilities. However, the data modeling software and the industrial field information model cannot be directly semantically compatible, and when the data modeling software and the industrial field information model are integrated with the industrial software, the realization of semantic interoperability still needs to be manually finished one by one, and the data modeling software and the industrial field information model have no universal applicability and reusability.
The industrial software comprises independent C/S software and service components in an SOA form, and the industrial software is required to be provided with the standard which accords with IEC62541-5, namely OPC UA information model, and supports the operations of importing, exporting, legitimacy checking and the like of OPC UA standard meta information and standard field information models supported by the OPC UA standard meta information; including but not limited to the implementation of parts below the information model of a specific OPC UA standard, such as specific implementation techniques of communication protocols, etc.; the industrial soft method software can be used as a client, a server or has two functions.
The PMML runtime environment may be a business software provided or open source software runtime environment conforming to PMML standards, and may be encapsulated twice as needed to provide a call interface function for state transition.

The PMML standard is an instantiation standard of the data mining process, and according to the execution process of the data mining task, related information of different stages of data mining is orderly defined: header information, data dictionary, data conversion, model representation, predictive rating. The data mining task mainly comprises the following steps: defining a data dictionary, defining data variables valuable to the analysis problem; preprocessing data, and generating variables suitable for modeling through operations such as derivatization, mapping, merging and the like of the existing variables; formulating an excavation mode, and designating a strategy for processing abnormal values and missing values in a data excavation modeling process; representing a data mining model, and recording information such as the structure, parameters and the like of the model; predictive evaluation, applying a test dataset to the obtained model, obtaining performance evaluation with various criteria.
The industrial software is mutually invoked to realize interoperation based on a standard information model, such as an FDT standard model, a MOM standard model, a PLCOpen standard model and the like, and is usually expressed in an XML form and distinguished by using identification ids after instantiation. The communication standard protocol of OPC UA not only realizes interconnection and intercommunication among different systems, but also supports the information model in various fields of the existing industry, supports inter-system interoperation, and has good compatibility to the original system.
The embodiment of the application discloses a PMML file and an integration method of a runtime environment and industrial software thereof, which avoid the customization operation of the traditional integration mode and reduce the manual configuration cost. Referring to fig. 1, an integrated method of PMML file and runtime environment and industrial software thereof disclosed in the embodiment of the present application includes:
s101: determining a PMML file to be integrated, and extracting key information from an XML description file of the PMML file, wherein the key information comprises any one or a combination of any several of head information, a data dictionary, a mining mode, a mining task, a target variable set and an output result element, and a calling interface function is provided in a PMML runtime environment;
in the embodiment of the application, the PMML file which needs to be integrated into industrial software can be determined, the XML description file in the PMML file can be obtained, and key information can be extracted from the XML description file. The key information may include, but is not limited to, header information, a data dictionary, a mining pattern, a mining task, a set of target variables, and output result elements. The PMML file running environment adopts a state machine mode to provide stateful services, and externally provides callable file loading, parameter setting, state query and state conversion interface functions.
In a specific implementation, the header information includes an information version and a model annotation; the data dictionary is used for defining the name, the measurement type and the data type of the original field required by the data model; the mining modes are used for defining variables required by the mining model; the mining task is used for defining relevant information of model training; the target variable set is used for defining target variables in the mining model; the output result element is used for recording a scoring result value set, and comprises an output variable name, a type and a calculation rule.
S102: extracting OPC UA information model and instantiation information in target industrial software in a file importing or real-time reading mode, wherein the OPC UA information model and instantiation information comprise any one or a combination of any of industry standards, object identifications, variables, characteristics and methods;
in this step, OPC UA information model and instantiation information may be extracted from the target industrial software. In particular, key information may be extracted from OPC UA model files, which may include, but is not limited to, industry standards, object identification, variables, characteristics, and methods.
It can be understood that when the information is obtained, the embodiment of the application can be directly imported in a file importing manner, and can also read the information in real time. That is, the imported data file can be received through a preset transmission interface, and an OPC UA information model and instantiation information extracted in advance in the data file are extracted; or OPC UA information model and instantiation information can be read from the target industrial software in real time.
It should be noted that the execution sequence of the steps S101 and S102 is not limited, that is, the step S101 may be executed first and then the step S102 may be executed, or the step S102 may be executed first and then the step S101 may be executed, or the step S101 and the step S101 may be executed synchronously, so as to shorten the working time.
S103: searching a mapping rule knowledge base for a corresponding mapping rule by combining the key information, the OPC UA information model and the instantiation information, and generating a mapping rule configuration file for realizing mapping between the PMML file and the OPC UA information model according to the mapping rule;
it can be understood that after the two types of information are obtained, the key information, the OPC UA information model and the instantiation information can be combined, the corresponding mapping rule is searched in the mapping rule knowledge base according to the semantics or the identification, and the mapping rule configuration file is generated according to the searched mapping rule, so that the mapping between the PMML file and the OPC UA information model can be realized by the configuration file. For example, according to the OPC UA information model identifier, industry standard information and PMML file identifier, a matched mapping rule is searched in a preset mapping rule knowledge base in an identifier matching mode; or searching semantic matching mapping rules in a preset mapping rule knowledge base according to the naming of the object, the variable and the method of the OPC UA information model and the naming information of the input, output, variable, parameter and other information in the PMML file.
Specifically, the mapping rule configuration file may include, but is not limited to: PMML file and instantiation identification, OPC UA information model and instantiation identification, PMML variable and OPC UA information model element mapping table and PMML operation environment standard function and OPC UA information model method call mapping table.
The mapping rule knowledge base may specifically include: identification information for performing OPC UA information model matching; identification, name and type information of the industry standard information, objects, variables and method node classes which are met; file marks, data dictionary variable names, measurement types, data types, parameter variables, target variables and output variable information for PMML file feature matching; determining mapping information of the elements based on the OPC UA information model identification and the PMML file identification; a data dictionary of unified semantics; the semantic mapping rule information between the OPC UA information model object, the variable, the method node and the PMML described data model, and between the input, the input variable and the running environment interface function. . In implementations, the user may pre-create a mapping rule knowledge base and edit it later. Specifically, an editing instruction issued by the user terminal aiming at the mapping rule knowledge base can be received, wherein the editing instruction is used for adding, deleting and modifying the mapping rule; and updating the mapping rules pre-stored in the mapping rule knowledge base according to the editing instruction.
Further, if the mapping rule is not found in the mapping rule knowledge base, a corresponding visual interface can be returned to the user terminal, and the user can manually configure the rules through the interface and update the rules into the mapping rule knowledge base after the configuration is completed so as to be reused later.
S104: and loading the mapping rule configuration file into a PMML running environment so that the PMML running environment can integrate the PMML file with the target industrial software through analytic compiling or dynamic loading.
After the mapping rule configuration file is generated, the file can be loaded into the PMML operation environment, and the PMML operation environment can realize the dynamic loading integration of the PMML operation environment according to the configuration parameters of the communication protocol by analyzing, compiling or dynamic loading, and simultaneously, the point-to-point and interface call mapping is rapidly completed.
It can be seen from the above that the PMML file and the method for integrating the environment and the industrial software during operation provided by the application can extract key information from the XML description file of the PMML file, extract OPC UA information model and instantiation information from the target industrial software, and search corresponding mapping rules in the mapping rule knowledge base, so as to generate a corresponding mapping rule configuration file, and the PMML operation environment can realize the integration of the PMML file and the target industrial software based on the mapping rule configuration file, and can automatically realize the rapid integration of the industrial software and the PMML file, thereby avoiding the customization operation of the traditional integration mode and further reducing the manual configuration cost.
