天铁烧结PLC智能故障诊断系统开发实践

Development and Practice of PLC Intelligent Fault Diagnosis System at Tiantie Sinter Workshop

叙述了天铁烧结PLC智能故障诊断系统的开发和应用。通过对外部设备故障状态锁存、PLC远程通道检测诊断以及故障状态数据采集、在线分析、存储的改进,实现了故障的智能诊断客户端查询。该系统成本低,使用难度小,能够有效减少电气故障发生率和排除时间,实现了对烧结生产的集中管控。

The author explains the development and application of PLC intelligent tault chagnosis system at Tiantie Sinter Workshop. Fault intelligent diagnosis and client query is achieved by improving external equipment fault state latching, PLC remote channel inspection and diagnosis, and the data collection, online analysis and storage of fault state. Low cost and easy in utilization, the system can effectively reduce electric failure rate and investigation time and enable the central management and control of sinter production.
