汽车电子嵌入式控制软件底层驱动的可视化配置屏蔽了底层实现细节,降低了配置难度,方便用户应用。但是,可视化配置的结构体嵌套使映射出的软件界面元素规则复杂化,且扩展芯片各模块结构体的未知性,使得映射规则难以普遍适用。为此,提出了一种可视化配置映射规则的挖掘方法,开发了针对芯片各模块结构体进行初始化配置的软件。通过对不同芯片底层驱动的实际配置,证实了该方法的有效性。 相似文献

The internal turbulent flow in conical diffuser is a very complicated adverse pressure gradient flow.DLR k-ε turbulence model was adopted to study it.The every terms of the Laplace operator in DLR k-ε turbulence model and pressure Poisson equation were discretized by upwind difference scheme.A new full implicit difference scheme of 5-point was constructed by using finite volume method and finite difference method.A large sparse matrix with five diagonals was formed and was stored by three arrays of one dimension in a compressed mode.General iterative methods do not work wel1 with large sparse matrix.With algebraic multigrid method(AMG),linear algebraic system of equations was solved and the precision was set at 10-6.The computation results were compared with the experimental results.The results show that the computation results have a good agreement with the experiment data.The precision of computational results and numerical simulation efficiency are greatly improved. 相似文献

注入式混合型有源电力滤波器的研究 总被引:1,自引:0,他引:1
根据配电网10kV高压侧对大容量谐波抑制与无功补偿的要求,提出注入式混合型有源电力滤波器拓扑结构(IHAPF),详细阐述了IHAPF的谐波抑制特性.同时结合某铜箔厂大型整流装置谐波抑制和无功补偿的工程实例,介绍了IHAPF的设计方法和软硬件构成,并从项目成本和治理效果两方面分析了IHAPF的应用优势. 相似文献

《民法通则》中有这样一条:居民住房,以居室窗台中心点在冬至日日照时间不足1小时的,每户按其居室被遮挡状况给予一次性补偿800~2000元。这就是说,对于花费了巨大代价买房子的人来说,最多2000元就可以买去他们世代采光的权利。享受阳光是每个人的愿望,但是由于土地资源紧张等原因,目前的很多建筑都存在着采光能力不足的问题,走进一幢写字楼,您几乎都会发现灯火通明———即使外面阳光明媚。现在,拥有5项专利的一种新型太阳能利用装置———阳光入室设备的出现将有望解决这些困扰人们多年的问题,成为太阳能利用领域… 相似文献
