摘 要
隨著社會(huì)經(jīng)濟(jì)的發(fā)展，汽車已經(jīng)深入人們的日常生活，私家車的數(shù)量急劇增加。汽車油耗支出已經(jīng)成為日常消費(fèi)很重要的一項(xiàng)組成。更多的人關(guān)心自己的汽車平均油耗，而汽車油耗的準(zhǔn)確計(jì)算相對(duì)比較復(fù)雜，很多汽車沒有提供具體的數(shù)據(jù)記錄和分析功能，所以采用智能手機(jī)這一非常普遍的計(jì)算設(shè)備提供快捷、方便、直觀的油耗記錄和統(tǒng)計(jì)分析功能成為非常實(shí)用可行的方案。
本文介紹了手機(jī)操作系統(tǒng)Symbian OS的特點(diǎn)和設(shè)計(jì)特點(diǎn)，設(shè)計(jì)并實(shí)現(xiàn)了一個(gè)運(yùn)行于Symbian操作系統(tǒng)下S60平臺(tái)的汽車油耗分析工具。它能幫助車主記錄每次加油的情況，保存到數(shù)據(jù)庫(kù)中，同時(shí)對(duì)數(shù)據(jù)進(jìn)行統(tǒng)計(jì)分析，為車主提供快捷、方便、直觀的油耗參考。文章首先介紹了本課題的背景，分析了該研究的必要性以及軟件的實(shí)用性。接著，對(duì)論文運(yùn)用到的關(guān)鍵技術(shù)進(jìn)行深入研究。了解了這些關(guān)鍵技術(shù)后，本論文描述了汽車油耗分析工具的功能分析與設(shè)計(jì)，對(duì)系統(tǒng)的需求、功能分析以及系統(tǒng)設(shè)計(jì)模式以及軟件算法等進(jìn)行了詳細(xì)論述。接著，對(duì)軟件的實(shí)現(xiàn)進(jìn)行了介紹。最后分析了實(shí)驗(yàn)的結(jié)果，并對(duì)該項(xiàng)目進(jìn)行了總結(jié)和展望。

Fuel Consumption system analysis tool

Abstract
As social and economic development, cars have become deeply in people's daily lives, in the number of private cars increased quickly. Gas expenditures have become a very important component of daily consumption. More people are concerned about their average gas expenditures of cars, gas consumption and the exact calculation of relatively complex, Many vehicles failed to provide specific data recording and analysis functions, And smart phone is a common computing equipment which can provide fast, convenient and visual record gas consumption and statistical analysis functions as a very practical and feasible option.
This paper introduces the cell phone operating system Symbian OS features and design features, Design and implementation of a run on the Symbian operating system S60 platform vehicle gas consumption analysis tools. It will help the owners of record of each refueling, the preservation of the database, and the data for statistical analysis, as the owner provides a fast, convenient and direct reference to the fuel consumption. The article first introduced the subject of the background of the study and the need for software utility. Then, the thesis that the use of key technologies for in-depth study. Understanding of these key technologies, this paper describes a car gas consumption analysis tool functional analysis and design of the system demand, Functional analysis and system design and algorithm algorithms for a detailed exposition. Then, the realization of the software was introduced. Finally, it’s the experimental results of the project and a summary and expectation.

Key words： Symbian; Car fuel consumption analysis tools; Data Management
