Abstract

The invention discloses a complex event processing system and method for the CPS application. The complex event processing system comprises an external physical environment, a sensor, an event generator, a complex event processing engine and a braking event management module; the external physical environment is used for providing the information under the physical environment for the integral system and accepting the control of an information system; the sensor is a bond for connecting the external physical environment with the event generator; the event generator is used for abstracting the information obtained from the external physical environment into unified format of basis event flows; the complex event processing engine is used for processing basic events according to defined rules in the system ad generating braking events; the braking event management module is used for distributing the braking events to an appropriate object to be sensed to process according to instructions in the events. According to the complex event processing system and method for the CPS application, the event response operation for the CPS application is implemented, the control on a physical system is achieved, and the effectiveness and the efficiency of the event processing can be improved.

Description

technical field [0001] The invention relates to the technical field of complex event processing (CEP), in particular to a CPS application-oriented complex event processing system and method. Background technique [0002] Cyber-Physical Systems (CPS) refers to a new type of hybrid system based on the mutual penetration and in-depth cooperation of computing, communication, and control to realize the close integration of computing processing and physical control. Generally speaking, computers and networks are used to monitor physical processes in real time and control them based on feedback from the physical system, while the physical environment affects the operation of the monitoring system, forming a closed-loop control system. [0003] CPS applications create a large amount of data while building a large number of sensor networks. After these data are processed, a large number of basic events can be generated. Complex Event Processing (Complex Event Processing, CEP) is use...
