液化天然气车辆年审系统 审核员模块设计 毕业设计 .doc

摘要 日益严重的环境问题与能源危机促使人们不断加大对车用发动机代替燃料的研究力度，天然气汽车因其经济型，安全性和环保性在替代燃料汽车中备受关注。天然气汽车工业的不断发展和液化天然气本身所具有的优良特性使液化天然气汽车正在成为研究热点，所以液化天然气车辆也将成为主流，人们也都开始陆续了解液化天然气装置，把汽车逐步都改装成液化天然气车辆，这样车辆在年检的时候就需要一个全新的液化天然气车辆的年审系统。 随着网络在生活中的应用，给人们带来了极大地方便，就使得车辆监督局也想设计用于年审系统的网页，本系统就是基于这两个问题设计的，以保定市质量技术监督局为对象，设计一套有管理员模块，检验员模块，审核员模块的网页对液化天然气车辆进行年审。本系统简明快捷，使用方便，及时有效，操作简单，界面明快。非常适合劳动量巨大，手续繁杂的年审系统。 关键字：液化天然气车辆年审系统 ，Java，B/S Abstract Increasingly serious environmental problems and energy crisis has prompted people to continuously strengthen the research of vehicle engine instead of fuel, natural gas vehicle because of its economical, safety and environmental protection has attracted much attention in the alternative fuel cars. The continuous development of auto industry and natural gas liquefied natural gas (LNG) itself has the good qualities of liquefied natural gas car industry is becoming a hot research topic, so LNG vehicles will become mainstream, people are starting to understand liquefied natural gas (LNG) plant, the car is gradually converted into liquefied natural gas vehicles, such vehicles in yearly check when they need a New Year of careful of liquefied natural gas vehicle system. With all kinds of application software in the application of life, has brought people convenient greatly, and makes the vehicle supervision would also like to design a set of software used in the year of careful system, the software design is based on the two questions, in baoding city bureau of quality and technical supervision as the object, have administrator module, design a set of checker module, the auditor module of software for liquefied natural gas vehicle inspection. This software simple and quick, easy to use, effective, simple operation, interface and lively. Very suitable for large amount of labor, cumbersome year careful system. Key words:, liquefied gas, vehicles, careful, system 1. 概述 2 1.1课题来源 2 1.2液化天燃气车辆国内研究现状 2 1.3研究的意义 2 1.4设计目标 3 2.需求分析 4 2.1系统定义 4 2.2功能需求
