【摘要】：近年來，我國大中型城市的小汽車的保有量越來越大，，公共車位相對缺乏、停車難的矛盾已經(jīng)成為城市規(guī)劃管理的一個突出問題。而目前國內(nèi)現(xiàn)階段運營中的停車場管理系統(tǒng)僅僅只是對車輛的停車時間進行統(tǒng)計，以實現(xiàn)自動計費和收費的功能；為解決車位緊張問題，部分城市的規(guī)劃超前要求新建的城市商業(yè)綜合體、居民住宅小區(qū)等設(shè)立多層停車場以及立體車位。然而，對于車位的管理工作多采用人工管理方式，多層停車場存在的問題也暴露出來，例如：駛?cè)胲囕v不能確知哪層，哪些位置還存在空位；無法及時準確的統(tǒng)計停車場內(nèi)空閑車位的數(shù)量及方位信息，管理人員無法對待停車輛進行有效的指引和調(diào)度。為了解決上述問題，本文設(shè)計了一種停車區(qū)位引導(dǎo)系統(tǒng)，解決了大型地下停車場多層停車信息不對稱的問題，使得駛?cè)胲囕v能夠方便獲得每層的剩余車位信息，快速方便的泊車。 本論文以三層地下停車場為例，設(shè)計了一個多層地下停車場區(qū)位引導(dǎo)系統(tǒng)；本系統(tǒng)由上位數(shù)據(jù)庫計算機控制中心、中心控制器、下位分層控制器和總?cè)肟诩案鲗尤肟贚ED點陣顯示屏共同組成。其中系統(tǒng)硬件部分包括車輛檢測轉(zhuǎn)換電路、多級陣列式LED顯示驅(qū)動電路以及LED點陣顯示屏，系統(tǒng)中控制器通過撥碼開關(guān)來選擇是中心控制器還是分層控制器，監(jiān)控室的中心主控制器通過RS-485的方式來與各層的分控制器進行通信，同時提供以太網(wǎng)口進行通信，有效避免了網(wǎng)絡(luò)的重建。其中軟件部分包括上位機軟件設(shè)計和下位機軟件設(shè)計，其中上位機軟件實現(xiàn)了停車場車位進行初始化、實時監(jiān)測各層車位的占用情況等功能；下位機軟件實現(xiàn)了LED點陣屏驅(qū)動、串口驅(qū)動和網(wǎng)口驅(qū)動等系列驅(qū)動控制功能，實現(xiàn)了LED點陣屏顯示、車輛信號檢測、主從控制器之間、以及主控制器與上位機間的通信功能。 系統(tǒng)經(jīng)過大量嚴格測試，結(jié)果表明，該系統(tǒng)可以快速準確對進出車輛信號進行檢測，將檢測后的車位信息傳輸給LED屏幕實時顯示，方便駕駛員快速地選擇合適的地方停車；系統(tǒng)整體設(shè)計合理，可靠性高，便于安裝，使用價值高。
[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.
