Design for RTDB Memory Structure of DCS

Abstract

Real-time database (RTDB) is an important part of the distributed control system (DCS), which is equivalent to a data processing center and functions as a data exchange area. The RTDB kernel carries the main features of the RTDB, supports task timing constraints, maintains a large amount of shared data, and ensures the integrity, consistency and real-time performance of the data. It also provides data access services for historical databases and human-computer interaction client programs, and is a bridge for data interaction between controllers and clients. The data in the real-time library is stored in memory. Therefore, the design of the RTDB memory structure directly affects the quality of the entire DCS system.
