Automotive Weighing Management System Design And Implementation

This topic is mainly focus on the research of developing the system of managingplatform balance for Zhenhai Refining&Chemical Co., Ltd in China PetrochemicalDevelopment Corporation, used by Chemical industry Department.This thesis mainly discusses the development of the system in accordance with thesoftware engineering thinking from the needs analysis, outline design and detaileddesign to the whole process of programming, testing, maintenance. Throughout thesystem development process, including the design of the back-end database to establishprogramming foreground application designed two large. Establish backgrounddatabase consistency and integrity of the data must be done, and good security. Thefront-end application design to achieve a friendly interface that must require a front-endapplication functionality must be in place, and user-friendly, to avoid misuse. Afteranalysis, the development of this system will be based on Microsoft’s VB.NETdevelopment platform, it contains a variety of object-oriented development tools. Aboutthe development process is the first in a relatively short period of time to establishsystems with the basic functions of the initial application prototype, and then use theevaluation of the initial prototype of the system according to the user’s ongoing demanditerative, continuous refinement and improvement, and to add new functionality untilthe final to form a viable system of user satisfaction.Application of the system as a standard management information system todevelop new B/S structure and the traditional C/S structure combined, give full playto the advantages of the two architectures and complement each other, trying to developa rapid response, safe and reliablesystems. Only fully take into account the security andinterests of the user of the system to be radically protection, but also makes the systemupgrade, update and maintain relatively easier, more convenient browsing queries.According to the needs of the practical application of the system of measuringinstruments with a9-pin RS-232C serial interface, very easy to communicate with thecomputer, call the VB MSComm serial communications control to achieve real-timedata acquisition to achieve real-time transmission of weighing data. System but can also exchange data in real time via the SAP RFC function with the company’s ERP system,information sharing and information via the ERP system in the enterprise networkreleased can be provided to the intranet terminal at any time to inquire about theirstatistics.
