在控制器与驱动器之间采用通信控制方式是机电装备控制技术的发展趋势。为了开发基于RS485通信技术的多台异步电机变频调速控制系统，以STC89C51系列单片机为控制器，以松下VF0C变频器为驱动器，设计了控制系统的硬件结构，分析了通讯协议MEWTOCOL-COM并设置了变频器的相关通讯参数，开发了单片机通信控制程序，并应用于多台风机的同步控制中。实践证明：该控制技术具有接线简单，控制准确、扩展方便以及成本低廉的特点。

The communication control technology between the controller and the driver is the developing trend of the electrome-chanical equipment control technology. In order to develop a variable frequency speed regulation control system for multi-motor based on RS485,a STC89C51 SCM was used as the controller and several Panasonic VF0C inverters were adopted as the drivers. The hard-ware structure of the control system was designed,the MEWTOCOL-COM communication protocol was analyzed and the correlative communication parameters of the inverters were set. The SCM communication and control program was developed and applied to the synchronous control of multi fans. The result shows that the control technology has the characteristics of simple wiring,high control ac-curacy,good expansibility and low cost.
