| In the past two decades, the research on Autonomous Decentralized System (ADS) has been carried out by the fundamental research, the applied research, the international academic exchanges and the works of standardization, has formed the more complete technical system.The premise of ADS is the dynamic changing of system' application environment and the equality of system structure. This premise conceals the set of current subsystem to constitute a total system, thus the temporal and the spatial criterion of system, are not fixed in the design time, but is in the run-time.The research on the dynamic evolution expression technology of the artificial evolution function, the latent function and the self-evolution function along with the spatial and temporal, constituted the three new research directions of ADS: Heterogeneous ADS, Role ADS and Intelligent ADS.The goal of this paper is to solve the spatial and temporal dynamic evolution problem of ADS system, to research correlation technology from heterogeneous data level, heterogeneous application system integration level and the spatial and temporal dynamic evolution expression of latent function, the key research topics are as following: Under the heterogeneous data coexistent condition, propose an autonomous decentralized protocol which support Quality of Service property; In the system integration of heterogeneous ADS, a gateway system integration model and its evaluation technology; the role ADS architecture and its realization technology which realizes the spatial and temporal dynamic evolution of functions; The formal description technique of role ADS.In the research aspect of Quality of Service property supported autonomous decentralized protocol, studies a Quality of Service property supported autonomous decentralized protocol, called QoS-ADP. Based on the semantic analysis of data in measurement and control system, define Quality of Service property of measurement and control system; Establishes one kind of effective self-description mechanism of data, realizes self-description of attributes such as time, precision and so on; Discusses data filtration and arbitration mechanism; Two kind of realization technology discussed based on the Ethernet and the CAN bus, and carries on the simulation. The result shown that, the QoS-ADP protocol has realized the trade-off between timely and reliable data transmission, the autonomous selection of data transmission. Based on this protocol, uses the redundant node, heterogeneous precision data sources may realize the system fault-tolerant, thus realized the system dynamic evolution in the data level.In the research aspect of integration model of heterogeneous ADS. establishes the gateway system model, discusses the length of information path optimization techniques, designs the data filtration protocol and the data filtration algorithm inside the gateway system, establishes the data throughput, the working ability model of gateway system, evaluating the working ability of gateway system through simulation. The simulation result indicated that, gateway system working ability surpasses a single-node gateway, the fault switch-off gateway and periodical switch-off gateway, it applicable to the integration of heterogeneous ADS, thus realized the system dynamic evolution in heterogeneous application level.In the research aspect of role ADS architecture and the key technologies, proposes the new idea and method of design and development for automation system, the role field and the data field dual driven architecture (RDDA) model;Proposed one kind of improvement local clustering algorithm (ILCA). realize a kind of mechanism which similar to the biological inspired natural selection mechanism; Configuration files realize the separation of strategy and mechanism, role arbitration realize the role transit of control center and sub-station, dynamic loading mechanism realize system dynamic update and synchronization. The simulation result indicated that, the role field and data field dual driven architecture-RDDA, is one kind of system construction method which support system evolution, and is independent of the strategy, has realized the separation of the strategy and the mechanism, the separation of function expression and the function realization, simultaneously has realized unified description to the master/slave structure, the client/server structure and the P2P structure, it may enhance the ability of fast reorganization, and dynamic reconfiguration of the system. The RDDA architecture and its correlation technology have demonstrated the technical feasibility and the latent application prospect of system dynamic evolution.In the research aspect of formal description method of role ADS, proposes the role autonomy description matrix, the RN-C scheme. Gives formal description of the role, the role space, the role action condition, uses the RN-C scheme to carry on the primitive description to the RDDA structure. Establish the UML statecharts of role and its label transition system, the model of role automaton, hierarchical automaton and extended hierarchical automaton. The role autonomy description matrix, has provided a macroscopic view of system, is suitable in the system analysis stage. The RN-C description scheme, has established the relation between the role and the behavior, as well as the mapping relation with the RDDA, has demonstrated the effectiveness to the system analysis and the design. The UML statecharts has realized the compound modeling of hierarchical and concurrent of role and behavior of RoADS, it has important value as the guidance to the analysis, design and realization of system. The composite functionγdescribed the hierarchical and compound relations between RA and the AA, the concept of configuration described the concurrent behavior of role transition among Agents of RoADS, has realized the compound modeling of hierarchical and concurrent of role and behavior of RoADS. These methods initially constituted a formal description frame of role ADS, and has laid the foundation for EHA based formal validation, the automatic code generation of system.
