停車場管理系統(tǒng)設計與實現(xiàn)-外文翻譯(存儲版)
【正文】 tion of car parking system on FPGAABSTRACTAs, the number of vehicles are increased day by day in rapid manner. It causes the problem of traffic congestion, pollution (noise and air). To overe this FPGA based parking system has been proposed. In this paper, parking system is implemented using Finite State Machine modelling. The system has two main modules . identification module and slot checking module. Identification module identifies the visitor. Slot checking module checks the slot status. These modules are modelled in HDL and implemented on FPGA. A prototype of parking system is designed with various interfaces like sensor interfacing, stepper motor and LCD.KEYWORDS :Finite State Machine。根據(jù)輸入信號，檢查插槽狀態(tài)。這里的 w1，w w3，w、clk，rest是輸入的信號。clk 是系統(tǒng)時鐘信號，rst 是控制信號，D(7:0) 是數(shù)據(jù)線，Z(3:0) 是步進電機的輸出信號，E 是液晶顯示器的使能信號，rs 是寄存器選擇信號。狀態(tài)可以是填充、 空或保留。對于模擬模型，橢圓形的心形的盒子用來描述過去的狀態(tài)，以及當前輸入的輸出。 HT12D解碼器的數(shù)據(jù)引腳與Virtex 5CI/O端口信號引腳連接。圖3（b）：步進電機與FPGA的接口（引腳分配） 射頻模塊：在本模塊中，紅外傳輸接收器用于檢測車輛是否存在。主要程序為 FPGA。Insop Song等提出基于 FPGA 停車系統(tǒng),采用模糊邏輯控制器 (FLC),主要優(yōu)點是計算時間大量減少了。該算法利用幾何計算路徑規(guī)劃。基于 FPGA 的設計也更靈活，可編程，可重新加載。圖中表明擁塞需要花更長的時間才能到從工作中尖峰時刻。為了克服這個問題。該系統(tǒng)具有兩個主要模塊即識別模塊和檢查模塊的插槽，識別模塊標識位訪客，插槽檢查模塊檢查有關插槽的狀態(tài)，這些模塊是在高密度脂蛋白中建模，在 FPGA 上實現(xiàn)。移動設備也可以用于支付交易。停車空間利用率高和免費、快速的現(xiàn)時間是提出研究的目的。在這篇文章中，提出在道路附近的停車場安裝攝像機和捕獲關于汽車顏色和車牌識別的信息，并保存到數(shù)據(jù)庫中。如果有空位，然后啟動電機，打開停車場入口的門。分配給FPGA的LCD的控制和數(shù)據(jù)線如圖3所示。并行數(shù)據(jù)由編碼器轉換為串行。 接口：在提出的系統(tǒng)LCD中，步進電機和RF模型接口是用FPGA完成的。如果有可用空間，然后液晶顯示可用空間其他液晶顯示沒有空間退出。然后模擬時鐘脈沖和重置應用會輸入。w，w w z、 clk 和重置是投入。在下圖的模擬輸入信號中，插槽 15 是可用的。識別和 new_member 也顯示結果識別模塊的輸出信號。1. INTRODUCTIONVehicle traffic congestion is a worldwide problem. In recent years, efforts have been made to introduce a method to reduce parking problems such as congestion, accidents and hazards.Figure1:Congestion Trends in Urban AreaAs shown in figure 1 congestion has clearly grown year by year. It creates a number of problems. Congestion used to mean it took longer to get to from work in the rush hour.Parking systems can also take advantage of innovative technologies in order to improve the ease and convenience of paying for parking. Now a day, Smart cards minimize transaction time by allowing a user to simply wave their card in front of a reader. Mobile devices can also be used in payment transactions. Public utilities need a parking system that can function efficiently and be integrated with the other urban city utilities. For allotment of parking slots there is no proper way thus parking management system fails in coordination and centralizing the information for an effective system. To avoid these problems, a design of an intelligent parking system is proposed,which will be implemented on FPGA to check its functionality.
