【摘要】：目前,国内的公交公司在管理方面普遍存在着盲区大、漏洞多、难度高的问题。它们具体表现在如公交车发车后找不到、甩站、不按规定道路行驶等,公交公司只能依靠稽查科的工作人员上路随机检查,这样不仅耗费人力物力财力,而且效率低下,效果不好。虽然有些城市已出现了公交来车预报系统,但大都只报距本站站数,并不报预计到达时间,这其中存在剩余路程难计算,行车速度因路况而不断变化等现实难题。针对上述不足,本文研究并设计一款基于嵌入式系统的公交智能预报系统,其目标是在现有的公共交通系统的基础上,利用GPRS技术和GPS全球定位技术,实现地理坐标、公交车编号、行车方向的无线采集,服务器通过接口调用调度系统数据库,对各项信息进行融合处理,获得预报站数和时间后,服务器将这些信息分包下发至其后各站台,为乘客提供来车预报信息功能。通过本系统,公交信息中心的管理员可以轻松掌握公交车的运营信息,不论是在车辆调度、车辆管理还是在车辆抢修等方面,都具有明显优势。同时站台显示终端不断刷新当前公交车的位置信息,乘客可以方便的安排自己的出行路线和乘车时间,信息服务更加便民化。经过测试,本系统运行稳定,效果良好。
[Abstract]:At present, there are many problems in the management of public transport companies, such as big blind area, many loopholes and high difficulty.They are manifested in the fact that, after the bus leaves, they cannot find them, dump the station, do not follow the prescribed roads, and so on. The public transport companies can only rely on the staff of the audit department to make random checks on the roads. This not only consumes manpower, material and financial resources, but also is inefficient.The effect is not good.Although some cities have developed bus arrival forecasting systems, most of them only report the number of stations from their stations and do not report the expected arrival time. There are some practical problems, such as the residual distance is difficult to calculate and the driving speed is changing because of the road conditions.In view of the above shortcomings, this paper studies and designs a bus intelligent forecasting system based on embedded system. The purpose of this system is to use GPRS technology and GPS global positioning technology to realize geographical coordinates based on the existing public transportation system.The bus number, driving direction of wireless collection, the server through the interface to call the dispatching system database, the information fusion processing, after obtaining the number and time of the forecast stations, the server subcontract the information to the subsequent platforms,Provide the passenger with the information function of coming car forecast.Through this system, the administrator of the public transport information center can easily master the operation information of the bus, whether in vehicle scheduling, vehicle management or vehicle repair, all have obvious advantages.At the same time, the platform display terminal constantly refreshes the current bus location information, passengers can easily arrange their travel route and travel time, the information service is more convenient.After testing, the system runs stably and the effect is good.
