VB在永磁同步电机调速系统中的应用

摘要

In the permanent magnet synchronous motor speed control system, under the VB environment, Use the RS232 / RS - 485 serial communication which is used by the MODBUS to make the computer(pc) commmunicated with the TMS320F2812.Expounded software design of the host (pc) which is in the VB environment and communication with TMS320F2812, by a way of communication with the crc check, to ensure the reliability of communieation, fully uses system resources ratio nally, raise efficiency and characteristics of com munication.Meantime, use the function of VB' store data, we can find out the historical data of motor easily.Through practical operation, based on vb environment, use of serial communication system has high rellab ility and practicability.%永磁同步电机的调速系统中,在VB环境下采用基于modbus协议的RS-232/RS-485串口通讯实现PC机与TMS320F2812的通信,设计永磁同步电机调速监控系统,详细描述了主机(PC)在VB环境下与从机(DSP)通信的软件设计.通信的检验方式中采用CRC校验方式,有效地保证了通信的可靠性,并且充分合理地利用工业现场系统资源的特点,提高了监控的有效性.同时运用了VB可存储数据的功能,可以方便地查阅电机的历史数据.通过实际的工业现场运行表明,采用VB开发的监控界面,具有很高的实用价值.
