摘要
为正确有效地处理传统的堆料机运行中的故障,提高系统自动运行的可靠性,以天津某港口煤炭输送系统设计为背景,在堆料机无人值守控制系统中应用专家系统技术,建立故障诊断信息系统。采用RSView32组态软件作为上位机监控软件,通过ControlNet网络以服务器/客户端的形式进行基于OPC技术的远程数据访问,实现对PLC工业现场的故障信号采集,并利用RSView32的VB接口来实现RSView32与故障诊断信息数据库的ADO通信。利用专家系统中专家知识对采集的故障信号进行分析处理并提出故障解决方案。实际运行结果证明,该故障诊断系统具有良好的实用性、有效性和开放性,对于出现的故障都能及时通过故障诊断信息数据库进行处理。
To handle the stacker failure effectively and improve the reliabity, based on expert system technology, a fault diagnosis system is designed for auto-stacker control of Tianjin coal transportation system. The configuration software RSView32 is utilized to realize the remote data access and signal acquisition through Server/Client mode based on OPC technology. And the ADO conununication between RSView32 and fault diagnosis database is realized through VB interface of RSView32. Using expert knowledge, fault signal is analyzed and schemes for dealing with the fault are presented. Test in the field shows the practicability, validity and opening of the fault diagnosis system.
