多层停车场区位引导系统的设计与实现
发布时间：2019-04-17 07:13
【摘要】：近年来，我国大中型城市的小汽车的保有量越来越大，，公共车位相对缺乏、停车难的矛盾已经成为城市规划管理的一个突出问题。而目前国内现阶段运营中的停车场管理系统仅仅只是对车辆的停车时间进行统计，以实现自动计费和收费的功能；为解决车位紧张问题，部分城市的规划超前要求新建的城市商业综合体、居民住宅小区等设立多层停车场以及立体车位。然而，对于车位的管理工作多采用人工管理方式，多层停车场存在的问题也暴露出来，例如：驶入车辆不能确知哪层，哪些位置还存在空位；无法及时准确的统计停车场内空闲车位的数量及方位信息，管理人员无法对待停车辆进行有效的指引和调度。为了解决上述问题，本文设计了一种停车区位引导系统，解决了大型地下停车场多层停车信息不对称的问题，使得驶入车辆能够方便获得每层的剩余车位信息，快速方便的泊车。 本论文以三层地下停车场为例，设计了一个多层地下停车场区位引导系统；本系统由上位数据库计算机控制中心、中心控制器、下位分层控制器和总入口及各层入口LED点阵显示屏共同组成。其中系统硬件部分包括车辆检测转换电路、多级阵列式LED显示驱动电路以及LED点阵显示屏，系统中控制器通过拨码开关来选择是中心控制器还是分层控制器，监控室的中心主控制器通过RS-485的方式来与各层的分控制器进行通信，同时提供以太网口进行通信，有效避免了网络的重建。其中软件部分包括上位机软件设计和下位机软件设计，其中上位机软件实现了停车场车位进行初始化、实时监测各层车位的占用情况等功能；下位机软件实现了LED点阵屏驱动、串口驱动和网口驱动等系列驱动控制功能，实现了LED点阵屏显示、车辆信号检测、主从控制器之间、以及主控制器与上位机间的通信功能。 系统经过大量严格测试，结果表明，该系统可以快速准确对进出车辆信号进行检测，将检测后的车位信息传输给LED屏幕实时显示，方便驾驶员快速地选择合适的地方停车；系统整体设计合理，可靠性高，便于安装，使用价值高。
[Abstract]:In recent years, there are more and more cars in large and medium-sized cities in our country, and the contradiction of parking difficulty has become a prominent problem in urban planning and management. At present, the parking lot management system only counts the parking time of the vehicle in order to realize the function of automatic charging and charging. In order to solve the problem of parking space shortage, the planning of some cities requires the establishment of multi-storey parking lot and three-dimensional parking space in the new urban commercial complex, residential district and so on. However, manual management is often used in the management of parking spaces, and the problems existing in multi-storey parking lot are also exposed. For example, it is impossible to know which floor and which positions are still vacant when driving into the vehicle; There is no timely and accurate statistics on the number and location of free parking spaces in the parking lot, and the managers can not guide and dispatch the parking vehicles effectively. In order to solve the above problems, a parking location guidance system is designed in this paper, which solves the problem of asymmetric parking information in large underground parking lots, which makes it easy for vehicles to get the information of the remaining parking spaces on each floor. Quick and convenient parking. Taking the three-storey underground parking lot as an example, this paper designs a multi-storey underground parking area location guidance system. The system is composed of the upper database computer control center, the central controller, the lower hierarchical controller and the LED dot matrix display screen of the main entrance and each layer entrance. The hardware part of the system includes vehicle detection and conversion circuit, multi-stage array LED display driving circuit and LED dot matrix display screen. The controller in the system selects whether the controller is the central controller or the hierarchical controller by dialing the code switch. The central controller of the monitoring room communicates with the sub-controllers of each layer through RS-485, and provides Ethernet port for communication, which effectively avoids the reconstruction of the network. The software part includes the upper computer software design and the lower computer software design, in which the upper computer software realizes the parking lot initialization, real-time monitoring of the occupation of each level of parking spaces and other functions; A series of drive control functions such as LED dot-matrix screen driver, serial port driver and network port driver are realized in the lower computer software. The functions of LED dot-matrix display, vehicle signal detection, master-slave controller and communication between master controller and host computer are realized. After a large number of strict tests, the results show that the system can quickly and accurately detect the signals in and out of the vehicle, and transmit the detected parking space information to the real-time display of the LED screen so as to facilitate the driver to quickly choose the right place to park. The overall design of the system is reasonable, the reliability is high, it is easy to install, and the use value is high.
