【摘要】：伴随经济与社会的发展,中国居民汽车保有量显著增加,致使城市中心及商业区出现了严重的停车难,难停车问题。本论文针对目前城市商业区地下停车场所带来的停车难问题及存在的各种弊端,设计了一套商业区地下停车场车位信息采集显示系统,旨在解决地下寻找空车位的难题,提高商业区地下泊车效率。基于商业区地下停车场所存在的问题,本课题首先研究分析了国内外地下智能化停车场的发展现状,并对远程信息采集及无线传输技术进行了研究,在此基础上,本文研究并实现了一种商业区地下停车场车位信息采集显示系统。该系统硬件设计主要包括三部分,一是终端信息采集器,每个采集器以单片机为控制芯片,连接多个超声波传感器进行车位信息采集;二是楼层中继器,指令控制每个信息采集器进行工作,同时将信息输出借助以太网转换器接入网络;三是区域显示控制器,接收采集器信息并将信息输出到区域显示设备。其中信息采集器,楼层中继器及区域显示控制器利用nRF905电台建立无线通信,制定通信协议,实现无线组网。利用C#技术设计了服务器车位动态显示软件和区域车位动态显示软件,服务器显示软件和中继器输出之间进行基于TCP传输协议的Socket通信,区域显示软件和控制器通过RS-232建立通信。两种显示软件分别植入地下停车场真实的车位地理信息全景图和停车场内某一区域车位地理信息图,每个车位用红绿标识对使用情况动态实时显示。同时编写嵌入式软件,控制各硬件单元执行功能。经实物测试表明,本系统硬件设计性能稳定,可以实时采集车位信息并发送,两种上位机车位动态显示软件可以稳定接收数据并动态显示车位使用情况。此系统提高了泊车者地下寻找车位的效率,达到了设计目标与要求,特别是对解决商业区地下停车所存在的突出难题具有更高的应用价值。
[Abstract]:With the development of economy and society, the number of cars owned by Chinese residents has increased significantly, resulting in serious parking difficulties and difficult parking problems in urban centers and commercial districts. In this paper, aiming at the difficult parking problems and various disadvantages brought about by underground parking places in urban commercial districts, a collection and display system of parking space information in underground parking spaces in commercial districts is designed in order to solve the problem of searching for empty parking spaces underground. Improve underground parking efficiency in commercial areas. Based on the existing problems of underground parking places in commercial areas, this paper first studies and analyzes the development status of underground intelligent parking lots at home and abroad, and studies the technology of remote information collection and wireless transmission. This paper studies and realizes a kind of information collection and display system of parking space in underground parking area of commercial district. The hardware design of the system mainly includes three parts, one is terminal information collector, each collector uses single chip microcomputer as control chip, connects several ultrasonic sensors to collect parking space information, the other is floor repeater, The instruction controls each information collector to work, at the same time, the information output is connected to the network with the help of the Ethernet converter; the third is the area display controller, which receives the information of the collector and outputs the information to the area display device. Among them, information collector, floor repeater and area display controller use nRF905 radio station to establish wireless communication, establish communication protocol, and realize wireless networking. The dynamic display software of server parking space and the dynamic display software of regional parking space are designed by using C # technology. The Socket communication between server display software and repeater output is based on TCP transmission protocol. Area display software and controller establish communication through RS-232. The two kinds of display software are implanted into the real panoramic map of parking space and the geographic information map of a certain area in the parking lot respectively. Each parking space is dynamically displayed with red and green signs. At the same time, write embedded software, control the execution function of each hardware unit. The physical test shows that the hardware design of the system is stable and can collect and send the parking space information in real time. The dynamic display software of two kinds of upper computer parking space can stably receive the data and dynamically display the usage of the parking space. This system can improve the efficiency of parking people looking for parking spaces underground, and achieve the design goals and requirements, especially for solving the outstanding problems of underground parking in commercial areas with higher application value.
