在信息物理融合系统中，通过部署在系统区域内的传感器节点来获得物理世界的信息。信息物理融合系统通常包含若干个异构的无线传感器网络。这些异构网络包含不同类型的传感器节点，这些节点具有不同的感知、计算和通信能力。将异构的传感器节点获得的不同类型的感知数据融合是一个十分重要并亟待解决的问题。在本文中，提出了基于多模态数据的事件模型，以事件为载体将多种不同模态的数据融合计算。文中描述并定义了信息物理融合系统中的事件，给出了基本事件和复合事件的定义，并提出了事件的合成规则。%In Cyber-Physical Systems( CPS),the information about physical world is obtained by sensors deployed in the system area. Generally,a CPS is composed by several heterogeneous wireless sensor networks. Heterogeneous sensor nodes in these networks have different capabilities in terms of sensing,computing and communication. Jointly processing the multi-modal data generated by heterogeneous sensors is an important problem. This paper proposes multi-modal event model, which interstates multi-modal data by events. The definitions and descriptions of atomic event and complex event,the composition rules of the event are proposed in this paper.
