摘要
为解决因泥泵输送试验台变频器使用端子控制方式与可编程逻辑控制器连接而引发的现场布线复杂、抗干扰能力弱、采集信号数量较少等问题,设计了基于USS协议通信的变频器控制系统,并根据实验台现有系统组成,分别设计了基于西门子200PLC与300PLC的USS协议通信方案,并对其进行了分析比较。结果表明,采用USS协议通信方式的变频器控制系统抗干扰能力强,可采集信号数量也有所提高。
The motor inverter of sand hydraulic transport stand connects its own control port with PLC. This traditional connection leads to the complex field wiring,easy to be interfered and less acquired signal. Aiming at solving the above problems in the existing experimental system,it designs a control system based on USS protocol,develops USS protocol communication programs respectively based on SIEMENS 300 PLC and 200 PLC,and compares these communication programs. The results show that the frequency converter control system with the USS protocol communication method has stronger anti- interference,and improves the number and accuracy of signal.
