A general communication mechanism for control systems

With the mutual promotion and development of computing technology, communication technology and control technology, building control systems by multiple machines has become a trend. The reliability of communication mechanism in these systems is the basic guarantee of system effectiveness. In this paper, a communication mechanism suitable for centralized and distributed control systems is proposed, which attempts to provide an effective framework for the design of communication subsystems in the system. The mechanism includes the logical structure of the communication network, RPC of Client-Server used in a control system, protocol and its basic functions. The basic function of the protocol is concretization and leaves a large expansion space, so this mechanism can be directly applied to the engineering design of medium and small control system, and has good flexibility and scalability.
