The Cyber-Physical Systems of Systems?CPSoS?is a combination of Cyber-Physical Systems?CPS?and Systems of Systems?SoS?.CPSoS is a CPS system with SoS features.The CPS system is a large and complex physical system that interacts in real time.To a certain extent,the physical system is equivalent to the embedded system[1].SoS refers to the integration of a limited number of independently operable systems.Therefore,the CPSoS system refers to the integration of a limited number of physical systems that are large and complex,can interact in real time,and are independently operable.The CPSoS system is built on top of CPS and SoS.It not only integrates their respective characteristics,but also has its own unique features.For example,CPS is composed of Cyber-Physical components,and components of CPSoS system are CPS.Therefore,the CPSoS system is a large,complex dynamic system distributed in space.In real life,different industries interpenetrate and blend,and unfriendly interaction between industries or intra-industry may result in high costs,unsustainable development and poor service.So the demand for CPSoS systems is growing.The CPSoS system is widely used in real life,especially in the fields of computer science,systems and control.In industry,it has become an extremely active research direction.The CPSoS system system plays a vital role in the future development of society.Taking intelligent community management as an example,the intelligent community system includes the CPS subsystem such as central management system,access control management system,intelligent analysis system,streaming media forwarding system,centralized storage system,platform client,etc.Among them,the central management system manages all CPS subsystems as the main hub of CPSoS system.the access control system management personnel's access,the streaming media forwarding system provides real-time video for the intelligent analysis system,storage system and platform client,The intelligent analysis system will analyze the real-time video and feed back the results of the analysis to the central management system.The central management system sends an alarm event to the alarm linkage system.The alarm linkage system notifies the centralized storage system to record and capture the video.At the same time,the central management system records the alarm information to the database and notifies the platform client.In recent years,Internet data has been generated at a rate of 2.5 megabytes per day[2].Such rapid speed has brought certain challenges to the storage of CPSoS system data.The arrival of the era of artificial intelligence supported by big data has also brought a new impact to the efficient processing of CPSoS system data.The management of mobile personnel in the intelligent community and the image storage of video surveillance are belong to the big data category.If these problems are not solved well,the community residents will face a series of personal property security issues.The key attribute of the CPSoS system is not its physical distribution,but its complexity.There is little difference between a factory with multiple production workshops and a rail transit system across multiple countries,they may have the same nodes.For intelligent community management based on complex CPSoS systems,the UML and E-R diagrams will be used for modeling separately.
