System integration interface adapter based on common information model (CIM)

Abstract

The invention relates to a system integration interface adapter based on a common information model (CIM). The system integration interface adapter comprises a common model storage layer, a data transmission layer, an interface adaptation layer and a system application layer. The common model storage layer is used for storing common model information and providing application functions of model display, maintenance and management. The data transmission layer is used for providing data transmission channels and carrying out data transmission with the interface adaptation layer and the common model storage layer. The interface adaptation layer is used for completing bilateral switching of a data model and standard operation of an interface. The system application layer carries out data transmission with the interface adaptation layer. According to the system integration interface adapter, a CIM provided by the international electrotechnical commission (IEC) 61970 / 61968 standard is adopted and Chinese industrial standards (CIS) interface specifications are adopted as the basis of system information interaction, so that the system integration interface adapter accords with the development tendency of electrical power system information integration, is compatible with an application system built by power enterprises and put into operation, supports new system interface design standard proposed by the trade union, can meet integrating requirements of the existing application system, has wide applicability and perspectiveness, and has good market promotion and application value.

Description

technical field [0001] The invention belongs to the field of power system information integration, and in particular relates to a system integration interface adapter based on a CIM model. Background technique [0002] IEC 61970 / 61968 series of standards, as an important basis for the application integration of electric power enterprises, proposed the public information model CIM (Common Information Model, public information model) and component interface specification CIS (Component Interface Specification, component interface specification) to unify EMS (Energy Management System , energy management system) / DMS (Distribution Management System, power distribution management system) information exchange semantic basis and interface function specification between application systems. CIM was originally published in the IEC61970 standard, mainly as the information semantic basis for energy management in the control center. CIM is an abstract model that uses the object-oriented ...

Problems solved by technology

[0004] With the continuous development of information technology, the interaction and sharing of data among various application systems in electric power enterprises are becoming more and more frequent. However, due to the development of computer technology, many relatively independent, heterogeneous, Closed subsystems make it difficult to carry out information sharing and business integration between different application systems, and the phenomenon of "information islands" formed makes it difficult to fully utilize internal resources of the enterprise, and it is difficult for business interaction, data sharing and synergy among various departments of the enterprise. Realization, the problem of system integration has become a major bottleneck in the business development of enterprises

[0005] At present, there are many kinds of enterprise application system integration solutions, but whether it is traditional point-to-point integration mode, or based on Common Object Request Broker Architecture (Common Object Request Broker Architecture, CORBA), Component Object Model / Distributed Component Object Model (Component Object Model, COM) / (Distributed COM, DCOM), sun server-side component model (Enterprise JavaBean, EJB) and other middleware products' hub-and-spoke enterprise application integration (Enterprise Application Integration, EAI) method, or the adoption of The enterprise service bus (Enterprise Service Bus, ESB) realizes the bus-type integration mode of the service-oriented architecture, and all face a common problem, that is, the problem of inconsistent data description semantics and syntax between heterogeneous systems, and the problem of inconsistent interfaces between systems; and In order to maximize the business integration of existing systems and achieve interoperability between systems, it is necessary to convert the data model through the interface adapter when transforming the system, giving it a semantic and grammatical structure that can be recognized and processed by other systems
