基于事件处理逻辑的应急处置信息系统研究

Research on Emergency Disposal Information System Based on Event Processing Logic

信息系统当前广泛应用于各行业应急处置工作中,辅助从业人员进行问题快速定位及处置。为减少信息系统内部各功能模块的耦合程度,降低系统平行扩展难度,该文研究一种基于事件处理逻辑的信息系统框架,将系统内部信息交互模式由接口调用转为事件流转。事件信息总线上存在各类事件信息,各服务模块经过统一鉴权后可以订阅并获取事件,各服务模块的处理结果也作为事件同步发布至事件总线,供其他需要的服务模块使用。该架构应用于不明无人机目标的应急处置信息系统,可以取得较好效果。

Information system is widely used in the emergency response work of various industries to assist the practitioners to locate and deal with problems quickly.In order to reduce the coupling degree of each functional module in the information system and reduce the difficulty of parallel expansion of the system,this paper studies an information system framework based on event processing logic,which changes the internal information interaction mode from interface call to event flow.There are all kinds of event information on the event information bus.After unified authentication,each service module can subscribe and obtain the event.The processing results of each service module are also published to the event bus as events synchronously for other service modules to use.The framework can be applied to the emergency disposal information system of unidentified UAV target,and can achieve good results.
