The invention discloses an event processing device. The event processing device comprises an event element, a message generation module, a message transmission module; the message generation module and the message transmission module shares the event element; event information is arranged in the event element; the message generation module generates a notification message based on the event information; and the message transmission module transmits the notification message based on the event information. As the event information is normalized into the uniform event element, the message generation module and the message transmission module share the event element, and the process of generating the message and the process of transmitting the message are mutually independent, relatively low coupling degree between the modules is obtained through cooperation of the normative event element, convenience is brought to optimization and upgrade respectively; meanwhile, the transmission process is clear and the maintenance is simple.
