A study of information objects for electrical energy RTU

According to the characteristics of monitored objects in smart grid systems, we unified the structure of monitored objects, defined 8 properties for a monitored object, i.e. identifier, access rights, status, type, object value, name , description and syntax. We used the monitoring information base to facilitate organization and storage of monitored objects. This method use little storage space and simple to use compared with the traditional use of a relational database. Monitoring information base use a tree-like hierarchical structure to store monitored objects to decrease the consumption of RTU memory resource and increase data access speed. Monitoring information base does not depend on the hardware structure, so that RTU has good compatibility and interoperability.
