Design And Implementation Of China Oilfield Services Limited Logging Data Transmission System

This study was designed and implemented by cosl logging data transmission system to data collection,transmission and reception,as the main line to provide logging data acquisition,data transmission management,logging data reception management,system configuration management functions,implementation of logging data acquisition,accurate transmission of information receiving and logging data,finally get variety of underground information,analyze its explanation.Cosl logging data transmission system adopts hierarchical structure,and the top layer,for the user to provide the user of the system operation page,based on the data layer technology at the same time,the business logic layer as the core,the resulting presentation layer,used in the user interface.Not only mutually independent and contact between layer and layer,in addition,the system also has the ability to scale,can according to the actual needs of cosl to add a new business functions.This system USES the Eclipse as a development tool,the Java programming language,combined with JavaScript and Oracle database development,at the same time,according to the system requirement analysis,system design,system implementation,system testing,the ideas for design and implementation of the system.According to the thought of software engineering,this paper adopts the combination of top-down and bottom-up approach to system design,the system is divided into the logging data acquisition management module,management module,management of logging data reception,data transmission module,the system configuration management module of the four major modules,among them,each module is divided into several small child function module.Well data acquisition management module,data acquisition equipment state management,timing Settings view,timing,data collection and real-time data collection and management;Data management module includes transmission parameters Settings,state management,manual transmission encryption and replacement of the data set;Logging data receiving management module includes receiving storage management,data query,data review,manual correction,trend analysis,and the cumulative amount analysis;System configuration management module includes equipment management,user management,log management and backup.
