Distributed Test System's Integrated Management Techniques

Along with the computer and the network technology development, the experimental system develops from the miniaturization to the large-scale, from the central system to the distributed system. The distributed experiment is a systemic engineering and it has some new characteristics during experiments. And then the management of experiments which is in the manual disperser way with difficulty originally has to adapt to satisfy the new requests of the distributed experimental system. The management of the distributed experimental system is a synthetic technology that could fulfill the experiments' requests which are carried out at local either the different department. That is significant to make sure the experiment is correctly carried on cooperatively and enhance the synthetic ability. So it has significance in theory and both in applying to research on the synthetic technology in the management of distributed experiment.The paper takes a process in clue of an elementary course from the test equipment management, the experimental resources collection, the testing supervisory control, tentative data processing, to the network data transmission and the experiment afterwards processes in the distributed experimental system.According to the application goal of the distributed experiment, this article has first analyzed the characteristic and the attribute of the management in the distributed experiment system, and then carries on the model and the composition design in this foundation to the distributed experiment management system.As a distributed system, the distributed experimental system also has the problem of the multi-task assignment and dispatch. In the distributed experimental system, the experimental mission has the distribution as well as the interaction, so the multi-task dispatch becomes extremely important. After analyzing the multi-task dispatch algorithm as well as the fault-tolerant technology, this article has used the dispatch strategy which the static assignment and the dynamic dispatch unify, and this strategy effectively enhanced the system performance.In the distributed experimental system, the data gathering is distributed, and the data must be storied high-speed and safely. Moreover the system has some certain requests on performance such as timeliness and so on. This article introduces the distributed data bank technology to carry on processing to the tentative data, andapplies the client/server computation pattern in accordance with the characteristic of the distributed experimental system. The application could simplify the tentative data processing greatly.Moreover, in order to reduce the influence creates to the distributed experimental system because of the non-uniformity of time, it is necessary for carrying on the tentative data to return to puts, the data analysis and the appraisal accurately to carry on clock synchronization to the system. The paper has studied the system time synchronization algorithm as well as the realization mechanism, and then programs to realize passive form time synchronization algorithm with Socket to solve time synchronization.Finally, after analyzing the demand of function in the management, this paper has carried on the functional design and elaborated the management flow as well as some central algorithm of each link in the experiment. And then the application of the synthetic technology in the management of distributed experiment system has been realized.
