分散控制系统在线可靠性评估系统研究与应用

分散控制系统(Distribued Control System,DCS)的可靠运行是发电企业安全生产和经济效益的保障。现有的分散控制系统普遍具备自检功能,但对于深层次可靠性参数尚未做到在线评价。通过各类通信协议收集与可靠性相关的控制设备状态参数,结合发电行业的相关标准,设计基于DCS设备运行状态数据的可靠性评估算法。通过设计开发和现场应用,实现了分散控制系统可靠性参数的监测和在线评估功能。

Real-time parameters monitoring system for underground equipment based on panoramic images

Complex terrain and working equipment in coal mine underground need a way to ensure coal mine safety. In this paper, the way to monitor the real-time status of underground equipment was put forward, and it was proved to be effective as commanding and dispatching system. Monitoring system for underground equipment based on panoramic images was effectively combined with real-time sensor data and static panoramic images of underground surrounding, which not only realizes real-time status monitoring for underground equipment, but also gets a direct scene for underground surrounding. B/S mode was applied in the monitoring system and this is convenient for users to monitor the equipment. Meantime, it can reduce the waste of the data resource.

倒退也创新

某电厂老师傅讲了一则没有结论的故事。从前,有个叫梁生金的地主,此主颇有才气,管理佃户们常有心得,数年之后,资产比父辈增长了十多倍。资产多了,佣人也多了,于是,爱思考的梁地主在聘用和管理上更是不断创新。例如对专门负责打扫内室等核心部门的勤务人员提出了如下标准:一不识字,二勤快,三不好奇不乱动,四不能贪,五模样周正,因为怕吓着家眷。一崔姓女子前来试用,梁地主开始了为期若干时日的考评。
