name="_Toc420922012"></a>近年来，随着我国经济的快速发展，人们生活水平的不断提高，物质需求和生活方式也发生着深刻的变化，以前属于奢侈品的汽车己经逐步走入了市民的日常生活。伴随汽车消费大众化和各种机动车辆大范围内的迅速普及，车辆对其配套设施特别是停车场提出了更高的要求。停车是"速度为零的交通”，停车场及附属相关设施是静态交通的重要组成部分。停车场收费管理系统是伴随着公用收费停车场这一新生事物而诞生的。 目前的多数停车场存在着以下几个问题，管理漏洞、系统的可靠性、独立性强、收费过程比较繁琐、劳动强度高、停车场利用率低下、票款易流失等。针对这些问题该停车场系统从以下方面进行设计。针对管理进行了优化，采用划卡消费和现金支付相结合，系统计时计费。采用Java高级编程语言和WEB相关技术开发设计管理系统软件，实现网络管理操作。优化后的系统使用方便、服务高效、收费透明、防止票款的流失，提高可靠性同时也提高了操作者的工作效率。 <ol> <li style="list-style-type:none"> <ol start="2"> <li class="15"><a name="_Toc513642557"></a>研究现状</li> </ol> </li> </ol> 停车场管理其实也就是信息化管理。在停车场的信息化中，包括停车场车位管理、停车信息管理、车主管理等信息化，信息化工作的开展有利于提高停车场的管理效率，提升停车场的竞争力。 要提高竞争力，首先要有良好的硬件环境，同时也要有好的客户服务，而要实现这些的办法就是信息化。本选题，针对停车场管理过程中的一些信息，对其进行信息化处理。在停车场管理过程中，主要涉及固定车位信息、临时车位信息、停车信息、车主信息等，通过对以上各个环节的信息化，提高档案的规范化管理，为以后的查询、统计作下基础。 停车场智能管理是现代化停车场车辆收费及设备全自动管理的统称，是将停车场基于计算机处理下的高科技机电一体自动化产品。根据恒业国际控股集团有限产品经理罗海江说明，其起源于2001年，发展的到现在日渐趋于完美，功能越来越面向国内外需求，系统操作也更加人性化。如今的停车场智能管理经过了早期对国外产品的模仿和学习阶段，目前进入到了一个产品创新阶段，紧跟市场需求步伐。目前国内听策划出系统生成企业有400多家，其中国产停车场系统产品约占市场比重的80%左右，国外停车场系统占20%。，据了解，在欧美地区，欧洲一些国家的停车产业发展已经有了50年的历史，已经达到了一种良性循环和有序发展。停车产业也已经成为年产值十亿美元的大产业。美国的停车产业每年收入越达到260亿美元，占全美GDP的3.25%。而我国的停车场车牌识别，牢牢占据主唱的位置。读卡器在停车场管理系统中扮演着重要的角色，如今它已由早期简单的接触式卡（磁卡/ID卡等），发展到感应式IC卡，再到RFID卡。而RFID卡是最具有话语权。 传统的停车场管理系统入口的部分主要由<a href="https://code99.top/wp-content/themes/van/template-parts/diy/go-link.php?a=aHR0cDovL2JhaWtlLnNvZ291LmNvbS9sZW1tYS9TaG93SW5uZXJMaW5rLmh0bT9sZW1tYUlkPTU0OTA2MDU5">车辆检测器</a>、<a

href="https://code99.top/wp-content/themes/van/template-parts/diy/go-link.php?a=aHR0cDovL2JhaWtlLnNvZ291LmNvbS9sZW1tYS9TaG93SW5uZXJMaW5rLmh0bT9sZW1tYUlkPTI5MTE1OSZhbXA7c3NfYz1zc2MuY2l0aWFvLmxpbms=">下雨天</a>易被淋打湿，上下坡道停车刷卡容易造成碰撞、溜车等事故，<a

因此，在优化上，本系统采用卡票结合的方式，在读卡器方面，采用RFID卡，解决了感应式近距离IC卡的问题，极大程度地提高了效率。对于车辆进入加入了车牌识别功能，识别车牌，进出停车场，针对于在停车场有会员的用户使用。对于临时用户来说，有读取票功能，动态的反应当前的车位情况，全过程采用视频监控，全方位，尽量做到无死角。 传统的停车场管理系统无法实时的动态处理，对于车主的信息也无法进行很好地保护、对于管理者的权限处理不当等问题，本系统都有很好地处理这些问题。其中的系统信息管理功能、车位信息管理功能、IC卡信息管理等功能良好的解决了这个问题。系统信息管理功能包括添加角色信息、管理角色信息、添加用户信息、管理用户信息、管理角色信息和管理用户信息模块可以对角色和用户进行增、删、改。车位信息管理包括添加车位信息、管理车位信息，管理车位信息模块可以对车主车位信息进行增、删、改。IC卡信息管理包括添加IC卡类型，管理IC卡类型。管理IC卡信息可以对车主的IC卡信息进行增、删、改。收费可以分为现金收费和卡收费，通常VIP用户进行卡收费，临时用户进行现金收费，软件管理实行分级权限制。对出口值班员来讲，其登录后可进入收费管理，期间该出口所有收费均自动记入该值班员名下并存入电脑数据库。由于值班员受权限限制，不能进入系统中更高的软件菜单项，所以对电脑所记录的数据无法干涉;上级管理者可以随时查询，核对或打印一个值班段或任何一段时间乃至整个停车场的工作记录。这样就从根本上杜绝了停车费用流失和财务统计的失误，同时系统自动运行，杜绝了人情车、霸王车造成的经济损失。设计一系列简约不简单的页面，与功能相对，提高信息处理的速度和准确性，能够准确、高效的查询和修改停车场的情况，从而提高效率。

不同的开发商遵循J2EE的开发规范，由于J2EE兼容性，使得数据信息具有很好良好的兼容性、安全性和可移植性。适用于各个平台。现如今，得到了大家的一致肯定，被大多数企业应用，提高开发效率。而停车场管理系统采用这个规范，其优良的可移植性和兼容性得到了很好的应用，易操作和学习。 <ol start="2"> <li style="margin-top:10px; margin-bottom:10px;

模型-视图-控制器的简称。其用于设计Web程序的模式。Model(模型)是程序处理代码逻辑的部分。View(模型)是程序处理数据部分。Controller(控制器)是处理数据传输过来与业务逻辑进行交互的部分。停车场管理系统采用MVC设计模式，方便开发人员修改或者调试代码，避免代码杂糅在一起。遇到问题时无法快速定位。而且MVC分层也简化了开发。不同的开发人员可以同时开发这三个逻辑，提高了开发效率，为开发商节约时间。   <ol> <li style="list-style-type:none"> <ol start="3"> <li class="15"><a name="_Toc513642562"></a>JSP介绍</li> </ol> </li> </ol> JSP其实是一个简单化的Servlet设计，一种面向对象的动态网页技术标准。其以Java为脚本语言，可以将java代码嵌入jsp页面，将代码和业务逻辑分离开来，实现动态交互。用户通过表单或者超链接提交数据，数据传到对应的Servlet中，通过Java代码处理，形成动态交互。JSP现今被大多数企业所应用，对于J2EE来说必不可缺。它使Web开发简化，提高效率，减少企业支出。   <ol> <li

Query就是查询的意思，更加方便快捷的查询页面控件，语法简单。jQuery是继prototype之后有一个优秀的JavaScript框架，兼容了多种browse(IE6.0+)，不但能够方便的操作文档和DOM、处理事件、实现动画效果，而且很方便的实现AJAX交互、兼容CSS3[4]。jQuery也提供了给开发人员在其上创建插件的能力，封装了JavaScript的函数，write less

RFID即为射频识别是一种无线通信技术，它是通过将无线电的电信号转化成无线电频率的电磁场，把在物品上标签附着的数据传输出去，用此来达到自动识别和追踪。它与条形码不同的是，不需要再识别器范围之内，也可以加入追踪器之内。 现今，大多数行业多运用了RFID技术。将数据标签附着在一套正在生产中的机器，便于厂家在线跟踪生产进度。当前也可以将其应用在图书馆中，便于管理和阅读者寻找书籍等等方面。停车场上也可以使用，汽车上装载的射频应答器，可便于进出车场的收费管理，避免难以预测的问题。提高停车场的效率。 <ol> <li style="list-style-type:none"> <ol> <li

车牌识别技术是通过监控车辆并自动提取车牌信息进行处理的技术。车牌识别在在现在交通系统中扮演着重要的角色，它以图形化处理、模式识别等技术作为基础，对得到定位车辆图像进行分析，从而得到每辆车的车牌号码，完成识别过程。再通过一些手段的处理可以实现停车场收费管理。停车场管理系统采用该项技术可以更加方便快捷的管理进出场车辆。   <ul> <li class="19"><a

在停车场管理系统的设计中应用MVC设计模式，便于开发人员设计代码，由于这三个逻辑可以同时进行，提高了效率，节省时间，且由于分层，将代码隔离开来，方便开发人员操作。且停车场管理系统采用RFID卡等等技术，方便车辆出入，增加智能化，便于管理。可以从这个角度得出，开发智能停车场是可行的。 <ol> <li style="list-style-type:none"> <ol> <li

本章内容包括系统类分析、核心业务设计、数据库设计三个部分，其中系统类分析需要给出系统类图和类的说明，需要注意在给出类图的时候只需要给出核心业务类，对辅助类如界面类、数据库连接类这种类型的不需要给出，如果所涉及的类（包括类当中的内容）较多时，应首先给出类间关系图（图中的类只有名称没有属性和方法），之后在单个类说明中给出具体类的类图，类图同样需要用WORD进行绘制。 核心业务设计主要描述的是完成某项具体业务时，类之间的消息配合，用时序图进行表述，时序图可以用其他工具绘制，但不能够有其他的颜色出现。 数据库设计主要描述在系统中需要持久化的对象，需要给出ER图，如果系统所涉及的实体(或实体的属性)较多时同样采用分层绘制的方法，顶层图给出实体间关系，下层图针对每一个实体进行具体绘制。 <ol> <li style="list-style-type:none">

近年来，随着我国经济的快速发展，人们生活水平的不断提高，物质需求和生活方式也发生着深刻的变化，以前属于奢侈品的汽车己经逐步走入了市民的日常生活。伴随汽车消费大众化和各种机动车辆大范围内的迅速普及，车辆对其配套设施特别是停车场提出了更高的要求。停车是"速度为零的交通”，停车场及附属相关设施是静态交通的重要组成部分。停车场收费管理系统是伴随着公用收费停车场这一新生事物而诞生的。 目前的多数停车场存在着以下几个问题，管理漏洞、系统的可靠性、独立性强、收费过程比较繁琐、劳动强度高、停车场利用率低下、票款易流失等。针对这些问题该停车场系统从以下方面进行设计。针对管理进行了优化，采用划卡消费和现金支付相结合，系统计时计费。采用Java高级编程语言和WEB相关技术开发设计管理系统软件，实现网络管理操作。优化后的系统使用方便、服务高效、收费透明、防止票款的流失，提高可靠性同时也提高了操作者的工作效率。
