The Design And Implementation Of AVI60 Gas Pollution Test Data Processing System

This thesis presents the design and implementation of gas pollution test data processing system which is the data processing software package matched with AVI60 multi-usages gas contamination detection equipment. This hardware equipment is the multi-usages device for detecting industrial and vehicle gas releasing through multiple detection methods on variable sensor combinations.This development of this software is oriented to the following objectives. The first is to implement the flexible, accurate and standardized data processing functions for released gas with all sample computations performed based on detection standards. The second is the maximized flexibility by basing this software on the general computational platform which is independent of specific underlying hardware techniques and instructions. The third is to implement this application with mainstream information techniques and capability to exchange data with the general database server. Adapt to these objectives this thesis finishes the following works. At first it analyzes the AVI60 gas detection data processing software's required functions and their use case models of detection task management, detected data processing and unit scaling management. On the second it presents the system AVI60 gas detection data processing's design scheme of software architecture, task management et al modules internal object constructions and typical data processing algorithm flows and database design scheme. On the third it describes the software programming techniques and test methods with focus on detection tasks management routines, data processing routines and scaling routines as examples.AVI60 software system is programmed with C++ with running environment of Windows platform. Its database can be any SQL-standard compatible mainstream platform such as SQL Server, Oracle and DB2 et al. Now AVI gas pollution test data processing system has finished its functional tests and probationary running with all function and performance test results reaching the expected development goals.
