| 摘要: |
| 人机界面是用户和机器联系的中介。文中所设计的人机界面主要应用于中型交流电机变频调速系统，在采用I2C总线（Inter IC Bus)通信协议的前提下，建立了一套以带有液晶显示LCD（Liquid Crystal Dispay)模块和键盘的单片机为“主”，以数字信号处理器DSP（Digital Signal Processor)为“从”的界面通信系统，实验证明，该 系统有较好的实时性和正确的数据传输，能实现对电机运行状态的监测、控制及故障排除，是一种较为可行的方案。 |

| Abstract: |
| The introduced MMI (Man Machine Interface)is mainly used for the induction motor drive system.Adapting I 2 C(Inter IC Bus)communication protocol,an interface communication system is built up,which takes the single-chip micro-computer with LCD(Liquid Crystal Display)and keyboard as the master and DSP(Digital Signal Processor)as the slave.The experiment shows that,the system is a practical solution for the monitoring,control and fault-elimination of motor operating states,which has correct data communication and better real-time performance. |
