【摘要】 本论文介绍了城市供水管网压力监测系统软硬件设计的主要内容。课题中，在硬件的通用性和可扩展性、软件的算法设计和代码优化上做了大量的研究和探讨。特别在软件设计研究中，提出了适用于数据采集系统的数据压缩算法——基于字典模型的自适应压缩算法；提出了类满二叉排序树的定义；提出了基于类满二叉排序树的先序遍历特性的最优化快速查找算法，它充分利用了折半查找和顺序查找各自的优点；提出了浮点运算乘法的改进算法；并在MCS-51汇编语言层次上对所有的算法加以实现。系统还利用由MODEM和公用电话交换网(PSTN)组成的通讯线路进行远程数据传输。最后，通过实验和实际应用验证了本系统软硬件设计的可行性。更多还原

【Abstract】 This paper presents main part of the hardware and software design of the Monitor and Collection System for Water Pressure of Pipe Network in Cities.In this paper,a lot of researches and exploration are applied to studying the universality and expansibility of hardware and the arithmetic design and code optimization of software.Especially,all of the following arithmetics or conceptions are worked out in the research of software design: self-adaptable compression arithmetic based on dictionary model for data Collection system,similarity full binary sort tree,a optimized quick search arithmetic and an improved arithmetic of multiplication in the floating-point operation.And all of the arithmetic are designed with MCS-51 assembly language. The quick search arithmetic,in which merits of both binary search and sequence search are used fully,are based on the specialty of preorder traversal in similarity full binary sort tree. And that,teledata transfer are realized through Lines of Communication(LOC) which is build-up by MODEM and Public Switched Telephone Network(PSTN).In the end,it is verified by experiments and application that the design of hardware and software is feasible in the Monitor and Collection System for Water Pressure of Pipe Network in Cities.更多还原
