【摘要】：随着城市机动车保有量快速增加,许多城市出现了日渐显著的“停车难、难停车”的问题。经常发生泊车者对现场周围停车场信息不了解,导致浪费时间、汽车违停和引起交通堵塞的可能。本文针对目前国内外智能化停车场管理研究的不足之处以及解决停车问题的迫切需要,在嵌入式技术、数据库技术、无线网络传输技术、计算机与网络传输技术等的支撑下,提出了一种基于3G传输的停车场大数据采集发布系统。本系统的设计采用了模块化的思想,将系统分为三个模块,分别为数据采集子系统、数据传输子系统、数据发布子系统。系统意在将一个区域内所有的停车场服务器上安装数据采集子系统以及3G传输子系统进行数据的采集和传输,在接收端将采集的停车信息存储在数据库中。本文前期研究表明,目前绝大部分智能停车场采用的是微软公司的SQL Server数据库进行管理,且数据库的表格标准统一。该数据库中存储了停车场出入信息。本系统所设计的数据采集模块是通过C#语言实现,该模块读取数据库中的停车信息,打包后将数据通过串口传输到数据传输模块。数据传输模块采用arm9开发板连接3G网卡传输停车数据,是本文重点研究实现的部分。本设计中定制开发了针对于系统特殊应用的Linux内核,在Linux平台上采用了socket编程的方式实现了向固定IP发送数据的功能。在拥有固定IP的服务器端接收到数据后,存入数据库中方便后期查询。最后信息发布模块是在C#平台上搭建,设计实现网站访问调用数据库中相关停车信息的功能。从而实现了泊车者,利用B/S模式能够在终端浏览实时的停车信息,寻找合适的停车位,方便用户出行目标。测试表明本系统能够有效的将一个区域内的各大停车场数据采集汇总并能够统一发布。本系统的提出能够解决许多城市日渐显著的“停车难、难停车”的问题,能够缓解目前供需紧张、寻找停车场困难等普遍现象。
[Abstract]:With the rapid increase in the number of motor vehicles in cities, many cities have become increasingly "difficult to stop, difficult to stop" problem. Often parking people do not know the parking information around the scene, resulting in a waste of time. This paper aims at the shortage of intelligent parking management research at home and abroad and the urgent need to solve the parking problem, in embedded technology, database technology, wireless network transmission technology, Under the support of computer and network transmission technology, a collection and release system of big data in parking lot based on 3G transmission is proposed. The design of the system adopts the idea of modularization. The system is divided into three modules: data acquisition subsystem and data transmission subsystem. Data distribution subsystem. The system is intended to install data acquisition subsystem and 3G transmission subsystem on all parking lot servers in a region to collect and transmit data. At the receiving end, the collected parking information is stored in the database. The previous research shows that most of the intelligent parking lots are managed by Microsoft's SQL Server database. The data acquisition module designed in this system is realized by C # language, and the module reads parking information in the database. After packaging, the data is transmitted to the data transmission module through serial port. The data transmission module uses the arm9 development board to connect the 3G network card to transfer parking data. In this design, the Linux kernel for the special application of the system is developed. The function of sending data to fixed IP is realized by means of socket programming on Linux platform. After receiving the data from the server with fixed IP, the data is stored in the database for later query. Finally, the information publishing module is built on the C # platform. The design realizes the function of website accessing and calling related parking information in the database, so that the parking person can browse the real-time parking information in the terminal by using the B / S mode, find the appropriate parking space, and make it convenient for the user to travel. The test results show that the system can effectively collect and aggregate the data of each parking lot in a single area and can be issued in a unified way. The system can solve the problem of "difficult parking, difficult parking" which is becoming more and more obvious in many cities. Can ease the current supply and demand tension, find parking lot difficulties and other common phenomena.
