A Method of General Data Interface's Design And Implementation Based On IEC 61850

摘要

this article describes a method of general data interface's design and implementation based on IEC 61850. This method puts interface data of communication and other function components in real-time database of the equipment, which also sets up a mapping method of the correlation of IEC 61850 and real-time database storage. And the method uses shared memory as the cushion space of data information exchange by the chain management technology of message blocks and subscribing/publishing distribution mechanism, and it provides a unified interface function for each application function module call. It is easy to implement the unified management of data interface, which can be more effective to complete the information exchange between IEC61850 data and a variety of advanced applications. It reduces the difficulty and complexity of the system integration, and improves the reusability of software.
