AN ALGORITHM FOR DOMAIN DECOMPOSITION IN FINITE ELEMENT ANALYSIS OF THE PDA AMMETER CHECKOUT SYSTEM

介绍了一个已经投入试运行的PDA校表系统。并针对该系统中任务划分效率低的现状,提出了一种新的区域划分算法。与传统的聚类划分算法相比,它具有时间复杂度低和灵活性高的优点。结合实际的可操作性引入了GPS全球定位技术,并将有限元分析和Bresenham画圆算法也加入到该算法中。最后通过VC实现了算法的仿真,仿真结果非常直观地证明了该算法的性能。统计和分析杭州计量所实际运行结果证明,加入该算法的PDA校表系统具有更高的效率。

A PDA system in the field test stage for ammeter checkout is presented. Considering the inefficiency in the task decomposition of the PDA Ammeter Checkout System, a new algorithm for domain decomposition is proposed. Contrast with traditional clustering algorithm, it costs less time and shows more flexibility. The technology of Global Position System, the algorithm of finite element analysis and Bresenham circling algorithm are introduced for the practicality. The simulation of algorithm which is implemented with VC represents the characteristics distinctly. The statistical and analytical results of practical running verify that the PDA system with this algorithm is much more efficient.
