基于嵌入式的变频器监控系统的研究与实现

摘要

In industry controlling, for a host-slave network, Modbus communication protocol can be adopted to transfer information between host computer an slave devices. On the base of host-slave communication, it is necessary to improve the veracity and velocity of exchanging information. By customizing WinCE operating system, programming serial drive and analyzing the principle of Modbus ASCII protocol, an communication program has been designed and transplanted into Samsung S3C2410 microprocessor successfully, realized the remote monitoring of VFD.%工业控制过程中,对于由一主机和若干从机所构成的网络,可以采用Modbus协议实现主从机之间的信息传递,在实现主从通信的基础上,提高信息交换的准确性和速率显得十分重要.通过定制WinCE操作系统和串口驱动编程,分析Modbus ASCII通信协议的原理,设计了EVC下Modbus ASCII通信协议的主从通信程序,并且将通信程序移植到Samsung S3C2410嵌入式处理器上,实现了对变频器的远程监控.
