本文選題：停車場　切入點：商務入口　出處：《大連海事大學》2015年碩士論文

【摘要】：在我國,大部分企事業(yè)單位停車場中都設立了商務入口通道,供內(nèi)部工作車輛和外來貴賓車輛使用。目前大多數(shù)停車場商務入口使用人力區(qū)分用戶類型以及控制車輛進場,不僅占用了人力資源,而且在車輛進場高峰期,產(chǎn)生停車場入口堵塞等問題。本文針對目前停車場商務入口控制系統(tǒng)的不足之處,將車牌識別技術(VLPR)、道閘控制技術、數(shù)據(jù)庫技術相結合,提出了一種商務入口VIP車輛自動入場控制系統(tǒng)的解決方案,實現(xiàn)了停車場商務入口VIP車輛快速、自動化入場。本系統(tǒng)分為硬件部分和軟件部分,系統(tǒng)構建在通用停車場入口系統(tǒng)之上。硬件部分設計了一個以STM32為核心的嵌入式控制器取代了原系統(tǒng)的控制板,作為核心控制單元,并協(xié)調(diào)原系統(tǒng)中地感線圈和攝像頭的位置以及地感線圈的個數(shù)；軟件部分使用C#語言在.NET平臺下設計了入口軟件、使用C語言在Keil平臺下設計嵌入式控制器工作流程。入口軟件設計了四個模塊：圖像采集模塊、RS485數(shù)據(jù)傳輸模塊、車牌信息獲取模塊、數(shù)據(jù)庫讀寫模塊。RS485數(shù)據(jù)傳輸模塊接收控制板發(fā)送來的采集圖像指令,調(diào)用圖像采集模塊采集車牌圖像；圖像采集成功之后自動調(diào)用車牌信息獲取模塊,并保存車牌信息；數(shù)據(jù)庫讀寫模塊在軟件初始化時建立兩個數(shù)據(jù)庫表,一個用來保存免費停車的用戶信息,另一個用來保存入場車輛信息,在車牌識別完成之后先判斷用戶類型,然后通過數(shù)據(jù)傳輸模塊向控制板發(fā)送控制道閘開關指令,并在車輛入場之后將車輛車牌號碼、入場時間等信息保存到數(shù)據(jù)庫中。經(jīng)實驗室環(huán)境測試以及現(xiàn)場為期三個月的運營表明：本系統(tǒng)能夠有效實現(xiàn)VIP車輛自動快速入場,和原系統(tǒng)相比車輛通行速率提高了至少4倍,并且VIP車輛的通行率達到96%以上。系統(tǒng)有效解決了停車場商務入口車輛堵塞和人力資源浪費的問題,并且本課題的設計理念可以應用擴展到停車場其他收費通道。
[Abstract]:In China, most of the parking lots of enterprises and institutions have set up business entrance channels for the use of internal working vehicles and foreign VIP vehicles. At present, most parking lots use manpower to distinguish user types and control the entry of vehicles. It not only takes up human resources, but also causes blockage at the entrance of parking lot during the peak period of vehicle entry. In this paper, the license plate recognition technology is introduced into VLPRA and gate control technology, aiming at the deficiency of the commercial entrance control system of parking lot at present. Combined with database technology, a solution of automatic admission control system for commercial entrance VIP vehicles is proposed, which realizes the fast and automatic admission of VIP vehicles at the commercial entrance of parking lot. The system is divided into hardware part and software part. The system is built on the entrance system of the general parking lot. In the hardware part, an embedded controller based on STM32 is designed to replace the control board of the original system as the core control unit. And coordinate the position of ground sensing coil and camera and the number of ground sensor coils in the original system. The software part uses C # language to design entrance software under. Net platform. Using C language to design the work flow of embedded controller on Keil platform, the entrance software designs four modules: image acquisition module, RS485 data transmission module, license plate information acquisition module, and so on. The database reading and writing module .RS485 data transmission module receives the image command sent by the control board, calls the image acquisition module to collect the license plate image, automatically invokes the license plate information acquisition module after the image acquisition is successful, and saves the license plate information. The database reading and writing module establishes two database tables when the software initializes, one is used to store the user information of free parking, the other is used to save the admission information, and the user type is judged after the license plate recognition is completed. Then the control gate switch instruction is sent to the control board through the data transmission module, and the vehicle license plate number is given after the vehicle has entered the vehicle. The information such as admission time is stored in the database. The results of laboratory environmental test and field operation for three months show that the system can effectively realize the automatic fast entry of VIP vehicles, and the speed of vehicle traffic is increased by at least four times compared with the original system. And the traffic rate of VIP is over 96%. The system effectively solves the problems of traffic jam and human resource waste at the commercial entrance of parking lot, and the design idea of this topic can be applied to other toll channels in parking lot.
