Graphical Programming Language Design for Decentralized Building Intelligent System.

The decentralized building intelligent system is a new type of building intelligent control system, which forms a decentralized network through intelligent nodes. It solves the difficulties in the configuration, modification, and information sharing of traditional centralized building control systems. However, because of the characteristics of no-center and parallelism, the decentralized system still lacks effective programming language support. In this regard, this paper designs a dedicated graphical programming language for the decentralized building intelligent system, then describes and explains from the static definition and dynamic interaction of graphics element two aspects. Finally, combining a case of control, this paper draws the connection diagram with the graphical programming language and makes an explanation, which verifies the feasibility of the graphical programming language for the decentralized system.
