The Real-time And Temporal-spatio Scheduling Algorithm Of Oriented To Cyber-Physical System

CPS is a comprehensive multi-demensional complex system.which combined by compute,networking,physical environment and unioned by compute,communication and control technoledge,the system must be perceived constraints caused by environment changes,and to predict these changes can be real-time.CPS is applied in various fields now,in addition these fields play an important role in society,they work together across the field,this put forward higher request for the performance of the system.Therefore,the study of the CPS scheduling algorithm could be meet the requirements of large CPS system with high performance request.In our country,the study for CPS is relatively weak,its scheduling algorithm is the key factor that affects the whole system.At present,both abroad and domestic,the study and improvement are still not meet the needs of actual. Most of domestic algorithmis traditional and single.certainly it will make the performance of the system into a bottleneck.unable to maximize the use of the resources.In the modern society.there are many instances of CPS which are under the influence of its scheduling algorithm,so the inherent performance of system is also affected seriously.In airport and station.this shortage is particularly obvious,and the impact of the this are huge. Therefore,in view of the algorithm cannot meet the demand of the system,this paper aim at establishing an optimize algorithm for CPS,improve the defects of existing algorithm,improve the overall performance of the system.Research for it is only for initial stage at present,so an efficient algorithm will be a technoledge revolution of CPS.In this paper,the analysis and argument for CPS are used Cellular Automata.We can clearly understand the the CPS’s feature byCellular Automata.In practical applications, the usage of CPS scheduling algorithm is widely.In this papper,through the analysis for existing systems at home and abroad,and find out the deficiency of them,finally.an improved scheme is proposed.At present,the typical usage of it are station scheduling and airport scheduling.Due to the station and airport owns huge data and has high requirement on real-time performance,thus for the corresponding scheduling system has very high demand,seek a more efficient scheduling algorithm will also be the develppment direction of the CPS accordingly.In this article,we will make an in-depth analysis of the railway station,to make the the schedule of station more effective.
