【摘要】 随着我国机动车保有量的持续增长，大城市停车难的问题日益凸现。停车诱导系统是解决停车难、缓解城市交通拥挤、减少空气污染、帮助驾驶员迅速找到停车泊位的有效途径。本文针对目前大城市停车难的现状，研究提出了大城市停车诱导系统的体系结构及其设计方法，综合互联网与移动通信技术实现了基于GSM网络的短消息业务(SMS)和WAP业务的无线应用系统的设计与实现。首先，本文探讨了课题的实际意义以及停车诱导系统的发展现状，并结合城市路网结构及城市管理模式，提出了大城市停车诱导系统应采用分布与集中相结合控制模式以及三层诱导管理方式，分析设计了系统的建设方案及其体系结构。所建立的大城市停车诱导服务信息系统主要由信息采集、信息处理／控制、信息传输和信息发布四部分组成，针对系统信息量大的特点，对所涉及的信息进行详细分类管理，并对系统各模块进行了讨论分析。其次，在研究GSM网络中短消息业务的体系结构、短消息的协议分层以及短消息发送／接收的PDU格式的基础上，设计开发了基于无线MODEM的短消息业务应用系统，包括短消息发送／接收功能、查询应用以及短消息定制等。最后，在研究无线应用协议和WAP系统构架的基础上，分析了WAP的特征和局限性，进而在J2EE平台上，采用MVC模式设计了WAP应用服务系统，构建一个具备初级功能的模拟环境。更多还原

【Abstract】 With the continuing growth of motor vehicles in our country, the problem of finding a parking place in the big cities is becoming more and more difficult. The Parking Guidance System (PGS) is an effective way to solve the problem of finding parking place, to ease the crowded traffic, to reduce the air pollution and to help the driver find parking space more quickly. Aiming at the current situation of hard parking in big cities this thesis studied and issued the systematical construction and its designing method of the parking guidance system, combining with the internet and mobile communication technology this thesis designed the wireless application system based on the Short Message Service (SMS) and WAP service of GSM internet and made it come true.Firstly, this thesis discussed the article’s practical significance and the current situation of PGS,considering the cities’ streets construction and its management style it put forward that we should adopt the control mode combining distribution with integration and 3-level guidance style for PGS in big cities. Meanwhile, it analyzed and designed the constructing program and systematical structure.The Parking Guidance System consists of the information collection subsystem, the information processing and controlling subsystem, the information transmission subsystem and the information distribution subsystem. According to the characteristics that the PGS has large amount of information, the information concerned in the Parking Guidance System is classified and studied the function of every subsystem.Secondly, on the base of studying system construction of short message service in GSM internet, protocol stratifies of short message and sending/receiving short message in the form of PDU, this thesis designed and developed the application system of short message service based on the wireless MODEM which includes the function of sending/receiving short message, inquiring about application as well as ordering the short message and so on.Finally, on the base of studying the wireless application protocol and WAP framework, this thesis analyzed the characters and limits of WAP. Furthermore, on the J2EE platform, it designed the application service system of WAP in the mode of MVC and made a simulation environment with an elementary function.更多还原
