基于时间算子的煤矿监控系统查询机制设计
Design of coal mine monitoring system query mechanism based on temporal operators
摘要
Abstract
Data search is one of the core functions of a monitoring system. The effective monitoring system should be based on a flexible and efficient query mechanism. But,at present,the query mechanism of coal mine moni-toring system is only concerned on the value variety of single sensors. It cannot provide queries about various ob-jects or the same object during different period,limiting the ability of the coal mine monitoring system. This paper proposed an event-driven query mechanism based on temporal operators. This new query mechanism will enhance the query ability and be a basic supporting technique for coal mine monitoring system.关键词
