摘要
介绍了西门子MM440变频器的RS485通信协议,利用VC++6.0中的ActiveX控件-MSComm实现了windows下计算机与变频器的串行通信控制。设计了一套全自动闭环控制系统,可方便有效的通过变频器调节离心机的运转,发挥离心机的功效,达到清除有害固相,回收加重材料的目的。
It focus on the RS485 communication protocol of SIEMENS MM440 converter, and presented the serial communication control which is implemented between the computer and the converter through MSComm of VC＋＋6.0. And it designs the system of full automatic control of closed loop. The system can adjust the ce effect of the ntrifuge ce revolution convenient and effective through the frequency changer, and exemplifies the ntrifuge for fulfilling the aim of removing useless solid and reclaiming heavy loader.
