【摘要】：传统的车位预约方式由于用户对区域内路况、停车场及车位等状况缺乏了解的原因,很难确保预约的车位适合用户。为提高用户预约车位的合理性及可靠性,本文在停车场实现对各车位检测管理的前提下,先按路况筛选停车场,再将最优停车场及车位的模型算法融入车位预约中,在车位预约算法的构建实现及预约App的设计等方面进行了研究。首先,对现有的影响用户选择停车场及停车位的因素进行学习研究,并将多个因素融合,分别构建出可用于预约推荐的最优停车场及车位推算模型。本文先利用路况信息对停车场进行筛选,再采用分阶段推荐的思路得出最优停车场;同时,本文设计的最优停车位推算模型在考虑用户利益的同时兼顾了运营商的利益。在完成模型设计后,本文利用Matlab编写应用程序,使推算模型得以具体实现。其次,为实现对用户预约数据及预约管理平台数据的高效管理,本文利用MySQL搭建了数据库系统,并通过MySQL-Front软件对数据库进行界面化管理。本文先对车位预约过程中需涉及的数据进行分析归类;再按照不同类别分别建立多个表格;接着绘制E-R图并建立属性表格;最后利用MySQL-Front及数据库语言完成各数据表项目的建立。随后,分析用户在完成车位预约时所需的操作及所要提交的数据,由此为依据来进行预约App的设计。本文在Eclipse的开发环境上采用java语言来完成预约App程序的编写,主要涉及各菜单界面XML文件设计和各项目Activity文件的设计编写。在完成程序编写后,利用Genymotion虚拟机对预约App进行初步调试。接着,根据预约App的各个项目及其需要提交和返回的数据,对服务器进行配置,从而实现App到服务器数据库的连接交互。本文采用Tomcat7.0为服务器平台,完成了多个项目的配置。然后,针对被预约的车位设计了管理方式,来提高车位预约的可靠性及时优性。本文先了解车牌识别算法并分析其在本系统内的可行性;随后本文对两种预约方法(排队预约和实时预约)进行研究,分析各自优点和不足之处并将两者进行融合,实现预约最优的更新;同时针对超时问题设计解决办法。最后,本文通过Genymotion虚拟机、MySQL数据库、Tomcat服务器及Matlab的联合调试,对本文的设计成果进行了测试。结果表明用户通过App可以完成预约数据的提交及最优车位的获取预约。
[Abstract]:Due to the lack of understanding of the road conditions, parking lots and parking spaces in the area, it is difficult to ensure that the reserved parking spaces are suitable for the users. In order to improve the rationality and reliability of the parking spaces reserved by the users, this paper, on the premise of realizing the inspection and management of the parking spaces in the parking lot, first screens the parking lot according to the road conditions, and then integrates the model algorithm of the optimal parking lot and parking space into the parking space reservation. The construction and implementation of parking reservation algorithm and the design of reservation App are studied. First of all, the existing factors affecting the choice of parking lot and parking space are studied, and several factors are fused to construct the optimal parking lot and parking space prediction model which can be used for booking and recommendation. In this paper, the road condition information is first used to screen the parking lot, and then the optimal parking lot is obtained by using the idea of stage recommendation. At the same time, the optimal parking space calculation model designed in this paper takes into account the interests of the operators while taking into account the interests of the users. After completing the model design, this paper uses Matlab to write the application program, so that the extrapolation model can be realized. Secondly, in order to achieve the efficient management of user reservation data and reservation management platform data, this paper uses MySQL to build a database system, and through the MySQL-Front software to manage the database interface. This paper first analyzes and classifies the data involved in the process of parking reservation; then establishes multiple tables according to different categories; then draws E-R diagram and establishes attribute table; finally completes the establishment of each data table by using MySQL-Front and database language. Then, the author analyzes the operation and the data to be submitted when the user completes the parking space reservation, and designs the reservation App based on it. In this paper, the author uses java language to complete the writing of App program in Eclipse development environment, which mainly involves the design of XML files in menu interface and Activity files in various projects. After the completion of the program, the use of Genymotion virtual machine reservation App preliminary debugging. Then, the server is configured according to the items of App reservation and the data that needs to be submitted and returned, so as to realize the connection interaction between App and server database. In this paper, Tomcat7.0 is used as the server platform to complete the configuration of many projects. Then, the management mode is designed to improve the reliability and timeliness of parking space reservation. In this paper, we first understand the algorithm of license plate recognition and analyze its feasibility in this system. Then, we study the two reservation methods (queue reservation and real-time reservation), analyze their advantages and disadvantages, and combine the two methods. To achieve the reservation of the optimal update; at the same time for the time-out problem design solutions. Finally, the design results of this paper are tested through the joint debugging of Genymotion virtual machine, MySQL database, Tomcat server and Matlab. The results show that the user can submit the reservation data and obtain the optimal parking space through App.
