摘要(Abstract)：

数据查询是监控系统的核心功能之一,有效的数据监控需建立在灵活、高效的数据查询机制之上。但目前,煤矿监控系统查询机制仅关注单一传感器数值变化情况,无法针对不同对象及同一对象不同时间段等查询,限制了煤矿监控系统作用。设计了一种基于时间算子的事件驱动查询机制,为增强煤矿监控系统查询能力提供基础支撑。
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 monitoring system is only concerned on the value variety of single sensors. It cannot provide queries about various objects 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.
