【摘要】：“公交優(yōu)先,綠色出行”已成為我國(guó)城市交通發(fā)展的重要目標(biāo)和指導(dǎo)方向,怎樣提升公交站點(diǎn)的通行能力、服務(wù)質(zhì)量和信息化水平已成為目前城市公共交通發(fā)展所面臨的問(wèn)題之一,欲解決此問(wèn)題,就必須解決現(xiàn)行公交站點(diǎn)內(nèi)“人車亂”問(wèn)題。產(chǎn)生這一問(wèn)題的根源是公交站點(diǎn)內(nèi)多采用自由�？糠绞浇M織公交車進(jìn)站停靠,該組織方式不僅使每輛公交車進(jìn)站�？繒r(shí)處于無(wú)序狀態(tài),而且還有可能導(dǎo)致車輛出站延誤時(shí)間變長(zhǎng)、站點(diǎn)內(nèi)停車泊位利用率低以及乘客人身安全受到威脅等弊端。所以為了從根源上解決站點(diǎn)內(nèi)“人車亂”的問(wèn)題,本文提出了一種多泊位動(dòng)態(tài)分配方法,并在此基礎(chǔ)上設(shè)計(jì)一種基于ZigBee的智能引導(dǎo)公交車進(jìn)站�？肯到y(tǒng)。本文結(jié)合公交車停靠特性和公交車�？繒r(shí)間計(jì)算模型,提出了一種多泊位動(dòng)態(tài)分配方法。該方法根據(jù)各待進(jìn)站公交車的�？繒r(shí)間、預(yù)到達(dá)剩余時(shí)間和站點(diǎn)內(nèi)停車泊位使用情況為它們分配泊位,引導(dǎo)各待進(jìn)站公交車按照分配給它們的泊位號(hào)有序進(jìn)站�？�,從而實(shí)現(xiàn)以動(dòng)態(tài)分配停車泊位方式組織各待進(jìn)站車輛進(jìn)站載客的功能。在多泊位動(dòng)態(tài)分配方法基礎(chǔ)上設(shè)計(jì)了一種基于ZigBee的智能引導(dǎo)公交車進(jìn)站停靠系統(tǒng)。首先對(duì)系統(tǒng)的功能需求及總體框架進(jìn)行了研究與分析,明確了系統(tǒng)的整體設(shè)計(jì)方案,然后對(duì)系統(tǒng)中的車載終端和站臺(tái)終端的硬件部分和軟件部分設(shè)計(jì)做了詳細(xì)的介紹,并根據(jù)PCB板設(shè)計(jì)規(guī)則,分別給出了車載終端和站臺(tái)終端的主控制板PCB圖和已安裝各模塊電路的硬件實(shí)物圖,設(shè)計(jì)布置在路邊的路由器節(jié)點(diǎn)以及車載終端與站臺(tái)終端之間的通信協(xié)議,測(cè)試和分析車載終端和站臺(tái)終端的最小系統(tǒng)硬件電路和主要功能模塊,最后對(duì)整個(gè)系統(tǒng)進(jìn)行聯(lián)調(diào),聯(lián)調(diào)結(jié)果顯示該系統(tǒng)能夠?qū)崿F(xiàn)智能引導(dǎo)公交車有序進(jìn)站�？�、乘客有序排隊(duì)乘車的功能需求,達(dá)到了系統(tǒng)的設(shè)計(jì)目的,該系統(tǒng)能提高公交站點(diǎn)的通行能力、服務(wù)質(zhì)量和信息化水平。
[Abstract]:"bus priority, green travel" has become an important goal and guiding direction of urban traffic development in China. How to improve the traffic capacity of public transport stations, The quality of service and the level of information have become one of the problems in the development of urban public transportation. To solve this problem, we must solve the problem of "people and cars in the current bus stations". The root cause of this problem is that the bus stop is organized by free stop mode, which not only makes every bus stop disorderly. Moreover, it may lead to the delay time of vehicle exit, the low utilization rate of parking berths and the danger to passengers' personal safety. Therefore, in order to solve the problem of "people and cars disorder" in the station, this paper proposes a dynamic allocation method of multi-berth, and then designs an intelligent guided bus stop stopping system based on ZigBee. In this paper, a dynamic allocation method for multi-berths is proposed based on bus stopping characteristics and bus stopping time calculation model. According to the stopping time of the buses to be put in the station, the method allocates the berths for them according to the remaining arrival time and the usage of the parking berths in the stations, and guides the buses to stop at the stations according to the berth numbers assigned to them in an orderly manner. Thus, the dynamic allocation of parking berths can be used to organize the incoming vehicles to carry passengers. Based on the dynamic allocation method of multi-berth, an intelligent guided bus stopping system based on ZigBee is designed. First, the functional requirements and the overall framework of the system are studied and analyzed, and the overall design scheme of the system is clarified. Then, the hardware and software design of the vehicle terminal and platform terminal in the system are introduced in detail. According to the design rules of PCB board, the main control board PCB diagram of vehicle terminal and platform terminal and the hardware object diagram of each module circuit installed are given respectively. Design the router node and communication protocol between the vehicle terminal and platform terminal, test and analyze the minimum system hardware circuit and main function module of the vehicle terminal and platform terminal, finally carry on the connection adjustment to the whole system. The results show that the system can intelligently guide the bus to stop in an orderly way, and the passengers can queue in order to meet the design purpose of the system, and the system can improve the traffic capacity of the bus station. Service quality and information level.
