【摘要】：随着经济和社会的飞速发展,人们对效率的要求越来越高。在居民外出活动时,传统的公交站牌和单一的公共出行方式已经不能满足人们的出行需求,针对这一系列现实问题,本文提出一种粘贴式LED公交电子站牌,并在此基础上提出公交车与公用自行车之间换乘算法。为居民提供简单、便捷、多元化的出行方式查询系统。首先,本文设计了一种粘贴式LED城市智能公交站牌,给出了系统软/硬件设计方案。该系统以STC12LE5A60S2芯片为控制核心,采用GPRS网络为传输网络,通过SIMCom有限公司的SIM900A芯片对公交信息服务器发送的GPRS数据进行接收,通过站牌上LED灯的闪、亮、灭显示此线路上游来车位置信息。LED灯通过粘贴方式粘贴在现有公交站牌的站点名称上方或下方,可为乘客提供方便、直观的公交实时位置信息,经济性好,易于改造施工。其次,系统硬件设计完成后,对整个系统各个功能进行调试和实现,是整个系统能够正常稳定的工作。最后,研究了公交车与公用自行车换乘系统的Dijkstra算法,给出公交车与公用自行车之间换乘的基本假设和模型建立,分为公交车与公交车之间的换乘问题和公交车与公用自行车之间的换乘问题两部分,并建立数据库对整个算法进行求解,给出6个起始站到终点站的最优路径。
[Abstract]:With the rapid development of economy and society, people demand higher and higher efficiency. When residents go out, the traditional bus stop sign and the single public travel mode can no longer meet the travel needs of people, aiming at this series of realistic problems. In this paper, a sticker LED bus electronic stop board is proposed, and on this basis, the transfer algorithm between bus and public bicycle is proposed, which provides a simple, convenient and diversified query system for residents to travel. In this paper, a sticker LED intelligent bus stop board is designed, and the software / hardware design scheme of the system is given. The system uses STC12LE5A60S2 chip as the control core and GPRS network as the transmission network. The GPRS data sent by the public transport information server is received through the SIM900A chip of SIMCom Co., Ltd., and the LED light is flashed and lit on the stop sign. The LED lamp is pasted above or below the station name of the existing bus stop by pasting, which can provide convenient and intuitionistic bus real-time location information for passengers and good economy. Second, after the hardware design of the system is completed, the debugging and realization of the whole system functions is the normal and stable work of the whole system. Finally, the Dijkstra algorithm of the bus and public bicycle transfer system is studied. The basic assumption and model establishment of the transfer between bus and public bicycle are given, which are divided into two parts: the transfer between bus and bus and the transfer between bus and public bicycle. A database is established to solve the algorithm, and the optimal path from six starting stations to the terminal station is given.
