Research On Assembly And Fault-tolerant Of Interface Component In Distributed Human-computer Interactive System

In order to solve the human-computer interactive interface and fault-tolerant in distributed system, Component assembly, fault-tolerant scheduling mechanism and characteristics of human-computer interface fault-tolerant scheduling are studied based on component technology in this thesis. A field of component-based human-computer interface design model and interface component assembly model are proposed. Model of human-computer interface describes using auxiliary tools to develop a user interface; the interface component assembly model describes the interface components built using the target system’s user interface. Fault-tolerant scheduling model for human-machine interface and corresponding scheduling algorithm in the distributed system are proposed based on the two models. This model is made up by the central scheduling component and the composition of multiple nodes, each of which contains local scheduling component interface, interface generation components. Central scheduling component and local scheduling component process system fault-tolerant scheduling and the scheduling component is the core of the system. In order to guarantee the reliability of the core component, Uniform Scheduling Processing Component, another fault-tolerant model of Primary Hot-Standby Cold-Standby is also promoted in this thesis. The design restriction of Interface Forming Processing Component and Human-Computer Interactive Interface Component concerning to the above-mentioned fault-tolerant scheduling model is proposed. This model is realized in the prototype demonstration system of the subject. Feasibility of the fault-tolerant scheduling model and algorithm is proved by the prototype demonstration system.
