摘要
为满足双转子压气机的高、低压压气机的单独试验以及联合试验的要求,研究了一种基于Profibus-DP总线的双转子转速数字给定方法,该方法以西门子S7-300 PLC为核心,应用现场总线Profibus-DP技术,以西门子Win CC为可视化监控软件,采用多圈绝对值旋转编码器数字给定方法,较好地实现了单转子转速给定控制和双转子转速的匹配给定控制功能。
In order to satisfy separate and double-joint trials for double rotor compressor's high and low pressure rotor, we design a double rotor speed digital given method which based on the field bus ProfibusDP, this method considers Siemens S7-300 PLC as the core,field bus Profibus-DP as the main body and Siemens Win CC for visualization monitoring software,adopting multi turn absolute value rotary encoder digital given speed,it better realized the functions of single rotor speed given control and double rotor speed matching given control.
