To achieve these goals , first of all , the national coding standards of various bar code systems have been learned . for the variety of bar codes , some commonly used id bar codes and 2d pdf417 bar code have been especially selected and their coding forms have been comprehended by consulting the national standard . secondly , computer algorithms for various bar code systems have been designed by combining the coding principles of various bar codes with the corresponding mathematic methods 首先,了解各种条码码制的编码国家标准,因条码种类众多,本课题特选取其中常用的几种一维条码和二维pdf417码,查阅了相应的国家标准了解其相应的编码形式;其次,结合各种条码的编码原理和相应的数学基础知识,对各种条码码制进行了计算机算法的设计。
The output of the geometry information and process information is completed by means of prescription and extract ion with code form and feature surface prescription method for the contour features , material features , precision features , technica1 features and management features of the revolving mode1 parts , that is , while parametric feature part drawing is formed a11 feature information is memorized in a data fi1e 采用特征表面描述法,通过对回转体零件的形状特征、精度特征、材料特征、技术特征、管理特征等关键因素以代码的形式进行描述及提取来完成零件几何信息和工艺信息的输出,即在特征参数化设计生成零件图的同时将全部特征信息存入一个数据文件中。
After completing the overall design for both the server and the client , the author has implemented fundamental real - time communications functions , such as real - time message transmitting , the management of current user and user " s friend , etc . the major research and characteristics related to the realization of mycomm are , only ansi c / c + + and some system calls of mysql and qt are used so as to embody the thought of os - free ; the real - time response and network security issues are resolved by the introduction of mulit - thread and daemon programming mode , as well as the conversion of a clear text signal to a coded form in the data domain of udp packet ; in order to provide a friendly user interface , a series of shell - based system management commands in the server and skin - based programming techniques in the client are developed based on qt development tools ; to solve the hardware dependent configuration problem , all system files are packed into a rpm file which can be automatically installed , avoiding revise and recompile " makefile " manually , therefore , making the software upgrade and distribution much easier 在此基础上,论文采用了商业大、中型软件设计中常用的cvs版本控制,完成了mycomm系统服务器和客户机的软件总体设计,实现了诸如实时传送消息、用户管理、好友管理等网络即时通讯的基本功能。本文的主要研究工作及其技术特点为:应用ansic / c + +语言、 mysql和qt系统调用完成了系统软件开发,体现了与平台无关的设计思想;引入了多线程及后台守护进程的系统设计方法,对用户消息原文经过加密后放在udp报文中进行网络传输,使该系统具有良好的时间响应性和安全特性;在服务器端,为管理员提供了基于命令行的系统管理方式;在客户机端,为了提供良好的人机交互界面,利用qt为开发平台,采用了流行的“皮肤”设计方法;为适应使用者计算机配置的差异,将所有系统文件打包制作成能自动安装的rpm格式,用户不须手工重新构造和编译makefile文件,因而更适合于linux环境下软件的发行和更新。
