Design And Implementation Of Electronic Equipment Repair System Simulation

In recent years, with the rapid development of electronic equipment technology and the increasing number of electronic devices, computer-assisted research means to achieve the simulation of electronic equipment maintenance are also increasingly emerging. By simulating the repair, maintenance training one can achieve cost savings, reduce manpower, material resources for the purpose, on the other hand can also be achieved for some complex equipment maintenance training. Therefore, the maintenance of electronic equipment simulation study developed a set of simulated maintenance system for maintenance training, has a very important practical significance.In this thesis, the design and maintenance of systems for electronic devices simulate the main line, based on the research and development status at home and abroad analysis, analysis of several key issues analog electronic equipment maintenance to be addressed, the proposed hierarchical design ideas, message pump communication mechanisms, static and dynamic combination of methods to construct the device model and plug-in architecture is designed to solve the problem of system expansion, embodied in the following aspects:First, for the realization of the modeling of complex electronic devices, the need for electronic devices fuzzy, abstract analysis and hierarchical decomposition processing, hierarchical design ideas and features of the proposed partial failure combined with an effective solution to the complicated electronic equipment and Unknown electronic device simulation problems. The idea is the theoretical basis of device modeling, and also post-simulation-based maintenance.Second, for a number of plug-in number, between the plug and the plug-in, relatively complex between the plug and the main characteristics of the communication, this paper presents the message pump mechanism and interface specification protocol plug-effective solution to the problem of communication between the main communication mechanism more, interactive situations more frequently exhibited strong adaptability.Third, for the large number of electronic devices, the actual specifications of different types, static and dynamic knowledge base approach combining simulation engine to achieve a common modeling and simulation of maintenance systems through its own plug-in architecture allows the system to continue to expand, sound, which effectively solve the problem of generic and extensible.Analog maintenance of electronic equipment is a complex and urgent need to solve the field, this paper avoids the complex electronic equipment complete physical simulation, to build a general-purpose analog service system from the abstract, inductive perspective, through the system in several electronic the practical application of the device point of view, this system effectively solve common analog maintenance difficult, simulation difficult, difficult problem of expansion. Ideas and methods presented in this paper in the analog service areas, with strong theoretical and practical significance.
