In large intelligent control systems,the weak electrical control system method of a master and multiple slaves combined is still one of the commonly used serial communication topologies at present because of its high scalability and high redundancy advantages.This paper first analyzes the deficiencies in certain aspects of various traditional serial bus methods and the defects of core communication information data in the control system that are easily leaked.To meet the high-standard serial communication requirements of some fields at present,this paper proposes a technical scheme for a high-speed serial communication device with one master and multiple slaves;then it analyzes the design of the serial com-munication scheme with one master and multiple slaves proposed in this paper,and elaborates in detail the design ideas of the hardware circuit schematic and software process;finally,the high-speed serial communication device with one master and multiple slaves is successfully applied in the control data acquisition system of a two-phase orthogonal frequency con-version electromagnetic stirring dedicated power supply with 12-pulse rectification,proving the feasibility of the one mas-ter and multiple slaves high-speed serial communication device proposed in this paper.
