Distributed Control System for Multi-motor Based on LabVIEW

研究了基于LabVIEW的电机集群控制。采用RS-232C串行通信方式实现上位机与群内各电机控制主板的通信,以实时修改系统控制参数、电机运动状态监控等功能。给出了基于LabVIEW的集群控制系统拓扑结构、具体集内系统结构、串口通信接口电路、控制面板设计流程图。结果表明:利用LabVIEW开发平台的友好界面,实现实时转速、电压、电流的控制界面图,实现了上位机实时监控电机运动状态。整个集群控制系统应用于电机实验教学中,通过形象的图表,简单的操作,加强了学生知识到实践的应用,实现了电机集群控制系统的实时监控。

Attention is concentrated on cluster control system for electric machinery based on LabVIEW, by using RS-232C serial communication to realize PC communication with one of control board, to realize real-time modify operating parameters of the system, monitoring the state of motor and so on. The control panel is given in this paper which is based on the software of LabVIEW, the cluster control system topology diagram ,specific set of structures within the system and communication interface circuit are given too. Experimental results are show that by use friendly interface, the speed, the voltage and current of the control panel have been realized. The interface which is based on development platform of LabVIEW has carried out real-time monitor the state of motor. The whole cluster control system is used experiment of electric machinery, by using visual chart, simple operation, the students have strengthened the application of knowledge to practice, and this experiment has realized real-time monitor of cluster control system for electric machinery.
