Research On Collaboration Theory Of Distributed Measurement System And Real-time Of Communication Platform

With the development of the techology of computer and network, researching on distributed measurement system becomes one of the hot problems in the field of automatic test. Howerver, existing resolutions to distributed measurement system still have great limit, e.g intellgence, self-adaptivity, collaboration, system load balance and integer view, and their capabilities need to be enhanced. Based on two key project, this paper studys on collaboration mechanim and real-time of communication platform in distributed measurement system comprehensively and systematically.The detail discussion are listed as follows:Acrroding to the agent theory, the feature of distributed measurement system and existing resolutions to distributed measurement system, distributed measurement system based on agent is established. In this model, classification and function of agent, structure and function of test softwarebus are given out. At the same time, dynamic communication among agents is descripted.Basing on particle swarm optimization, this paper gives the algorithm on coalition formation and the sub-task allocation in the agent-based distributed measurement system. The simulation results illustrate that it is in advance of genetic algorithm. Meanwhile, for the synthesis of belief degress in the system, a recurrence algorithm is given. It not only takes full advantage of existing results, but also overcomes problem of positive and negative invalidations that exit in current algorithm.For agent-based distributed measurement system, firsly from the overall system point of view, broad model of system is established, and then stability of system is analyzed, Secondly, support model of system is set up by FCM and a new coobration strategy is descibed and proved. Finally, we analyze stability of coalition formation systematically.A feedback control real-time scheduling algorithm for switched Ethernet is optimized through analysising real-time of traditional Ethernet and switched Ethernet accurately. The test results illustrate that this algorithm can solve real-time of switched Ethernet effective and satisfy to real-time communication. Combined with a project of developing the aeroengine simulated altitude facility distributed test system, and based on above the theory, it verifies collaboration mechanism and real-time of communication platform effevtive.
