The embodiment of the present invention is achieved in that a kind of method of the low-power consumption real time data processing based on CPS, and the method for being somebody's turn to do the low-power consumption real time data processing based on CPS comprises the following steps:
Based on time external event, trigger;
Judge whether to belong to basic trigger event, belong to basic trigger event and call elementary event trigger controller;
Do not belong to basic trigger event, judge whether Problem with Some Constrained Conditions, there is no constraint condition, call without constraint complicated event and trigger control processor;
Prescribed Properties calls belt restraining complicated event and triggers control processor.
The method of low-power consumption real time data processing that further, should be based on CPS is usingd and can be calculated with the core of communicating by letter and realize monitoring, control and integrated CPS as a physics and engineering system by one.
Further, the method for low-power consumption real time data processing that should be based on CPS is controlled for the dynamic topology of the CPS system of the moving assembly that has wireless dynamic topology and control, understands and the restructural topological structure of final control relevant real-time performance, safety and robustness.
Further, the informationization that CPS comprises physical process and the physics realization of information, can process the event in the time of being distributed in and space, possesses the ability of room and time characteristic.
Further, the disposal route of the time parameter of Event triggered controller is:
Time processing controller judges whether to belong to event continuous time, belongs to event continuous time, calls non-linear event handling function continuous time, does not belong to event continuous time, calls the non-linear event handling function of discrete time.
The method of the low-power consumption real time data processing based on CPS provided by the invention, using CPS as a physics and engineering system, can calculate with the core of communicating by letter and realize monitoring, control and integrated by one; By the informationization of physical process and the physics realization of information, considered the multiple resources characteristic of construction system, comprise cost, speed, these three key elements of capacity, met CPS real time data for timeliness, promptness attribute specification.The present invention considers the time as a parameter, for the real time data management low-power consumption problem based on CPS, provide good solution simultaneously, CPS is as a kind of new theory developing on the embedded system basis from traditional, solved the problem of data volatility, reliability, energy consumption aspect.
