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,了解各種條碼碼制的編碼國家標準,因條碼種類眾多,本課題特選取其中常用的幾種一維條碼和二維pdf417碼,查閱了相應的國家標準了解其相應的編碼形式;其次,結合各種條碼的編碼原理和相應的數學基礎知識,對各種條碼碼制進行了計算機算法的設計。
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,通過對回轉體零件的形狀特征、精度特征、材料特征、技術特征、管理特征等關鍵因素以代碼的形式進行描述及提取來完成零件幾何信息和工藝信息的輸出,即在特征參數化設計生成零件圖的同時將全部特征信息存入一個數據文件中。
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 在此基礎上,論文采用了商業大、中型軟件設計中常用的cvs版本控制,完成了mycomm系統服務器和客戶機的軟件總體設計,實現了諸如實時傳送消息、用戶管理、好友管理等網絡即時通訊的基本功能。本文的主要研究工作及其技術特點為:應用ansic / c + +語言、 mysql和qt系統調用完成了系統軟件開發,體現了與平臺無關的設計思想;引入了多線程及后臺守護進程的系統設計方法,對用戶消息原文經過加密后放在udp報文中進行網絡傳輸,使該系統具有良好的時間響應性和安全特性;在服務器端,為管理員提供了基于命令行的系統管理方式;在客戶機端,為了提供良好的人機交互界面,利用qt為開發平臺,采用了流行的“皮膚”設計方法;為適應使用者計算機配置的差異,將所有系統文件打包制作成能自動安裝的rpm格式,用戶不須手工重新構造和編譯makefile文件,因而更適合于linux環境下軟件的發行和更新。
