在电子技术中，频率是最基本的参数之一，又与许多电参量的测量方案、测量结果都有十分密切的关系，因此频率的测量就显得更为重要。测量频率的方法有多种,其中电子计数器测量频率具有精度高、使用方便、测量迅速，以及便于实现测量过程自动化等优点，是频率测量的重要手段之一。在本次毕业设计中我们选择使用单片机来制作数字频率计，并在实际制作中采用了直接测频法。利用延时产生的时基门控信号来控制闸门，通过在单位时间内计数器记录下的脉冲个数计算出输入信号的频率，最终送入LCD中显示。这样制作出来的频率计不仅可以满足设计题目的参数要求，而且具有了单片机的稳定性和成熟性，且控制能力强，是一种低成本，高可靠的设计方案。-In electronic technology, the frequency is one of the most basic parameters, but also with a number of electrical parameters of the measurement program, the measurement results have a very close relationship between the frequency of measurement, therefore it is even more important. Measurement of the frequency of a number of means, electronic measurement of the frequency counter with high precision, easy to use, rapid measurement, and measurement is easy to realize the advantages of process automation is an important means of measuring the frequency of one. Graduates in this design we have chosen to make use of single-chip digital frequency meter, and used in the actual production of a direct

针对某些嵌入式系统中处理数据量大和速度要求高的特点, 在剖析了uCOS - Ⅱ内核工作原理的基础上, 提出一种应用于uCOS - Ⅱ中的大容量内存文件系统的实现方案1 该方案通过在内存中建立文件系统, 将临时数据有效组织于内存中, 既提高访问速度又节省外存空间-against certain embedded systems handle large data volume and speed of high-features in the analysis for uCOS-II core principle on the basis of An application for uCOS-II, a large memory capacity of the file system to achieve a program of the program in 1988 through the construction documents, data will be temporarily effective organization in memory, not only increase the rate of savings Disk Space

太原理工大学硕 士 学 位 论 文 摘 要 派送调度问题是物流管理领域中一个重要的课题，是大型 超市集团、大型零售连锁店、物流派送中心及工业生产企业共 同存在的问题。随着跨地区、跨地域的经济活动日益加强，迫 切要求解决物资流通当中合理调度运输工具的问题来有效实现 企业生产计划、减少物资库存，从而提高工商企业的生产效率。 目前对于派送调度问题的研究主要集中在对运输工具的配置和 静态调度领域，这些研究工作已经取得了丰富的成果，并且研 究结果也主要应用于决策和管理方面。但是对于运输工具运行 情况变化和派送任务动态产生和调整关注较少，同时，在线派 送调度的计算机系统产品也较少-Taiyuan University of Technology master"s degree thesis Abstract delivery scheduling problem is the logistics management field an important issue, is a large supermarket groups, large retail chains, logistics distribution centers and industrial production enterprises to the problems that exist. With trans-regional and cross-boundary economic activities increasing, it is urgent to address the flow of goods among them reasonable means of scheduling problems to the effective realization of production plans to reduce material inventory, thereby improving business productivity. Current scheduling problems for the delivery of concentrated mainly in the transport and distribution of static scheduling field
