( 从太原市公交查询系统建立的必要性出发, 进行了公交查询算法的研究, 主要探讨了包括最短路径查
询及最少花费查询及数据库管理的公交查询系统的实现。 该系统采用了V ISU AL BA S IC 610 为开发工具,
M ICRO SO FT A CCESS2003 为后台数据库, 开发了基于太原市公交线路的公交查询系统。具有线路查询、换乘
查询、 站点查询、 数据管理等一系列功能。
((From the city bus system the need for inquiry, carrying out a public inquiry method of research, focused on the shortest path, including at least inquiries and inquiries and database management to spend the public inquiries system. The system uses a V ISU AL BA S IC 610 for the development of tools, M ICRO SO FT A CCESS2003 as the background database, developed based on the city' s public transportation bus lines inquiry system. with line inquiries, transfer information, site information, a series of functions such as data management.)

:介绍了一种基于数字信号处理器(DSP)的移相调频(Phase-Shifted and Frequency-Varied,PSFV)PWM控制
逆变电源,给出了主电路拓扑结构,分析了其控制原理并设计了其控制程序流程图。新颖的PSFV 控制能够实现输出
电压90%的调整率,输出电流波动小于单纯移相调功PWM方式,并在轻载时保持连续。功率开关器件零电压零电流
通断(Zero-Voltage-Zero-Current Switching,ZVZCS)软开关的实现,有利于进一步提高开关频率和降低开关损耗。采用
高性能的专用DSP 芯片TMS320F2812 实现了系统的数字控制,满足了系统控制的灵活性和实时性,减小了系统的
体积和生产成本。仿真分析和实验结果证明了此控制模式的可行性与合理性。()
