摘要
该文针对天然气加气子站的压缩机设计了监控系统与数据采集系统,通过解析PPI通信协议解析一条读指令,将PLC中所有寄存器的数据进行读取,使得监控系统能达到企业要求的实时性。简单介绍了系统实现的技术架构,最后指出利用参数测量法对压缩机进行故障诊断。
In this paper,the structure were designed of natural gas compressor monitoring system and data acquisition system. All the register data in PLC could be obtained to meet the real-time requirement by an instruction of PPI protocol.The technical framework of system was introduced simply,and the parameter method for measuring was put forward in fault diagnosis of natural gas compressor.
