摘　　要：针对我国交通拥堵所带来的问题,本文以城市出租车为载体,从智能交通的GPS数据采集入手,以Delphi为开发工具,对浮动车采集的数据进行研究。同时,采用第三方支持多线程工作的串口通信控件Spcomm,实现串口通信和GPS数据的采集。研究结果表明,通过GPS信息可以在任意时间获取任何地点的位置信息,并能获得相应载体的速度和方向等信息,该方法实现了GPS数据的接收、存储、转换和文本写入,同时该方法也可对工业数据采集、路灯、水电气实时监控,具有一定的实际应用前景。In view of traffic congestion problems in our country, this paper studies on floating car date by taking the city taxi as the carrier, collecting intelligent traffic data by using GPS, and using Delphi as a development tool. At the same time, using serial communication control Spcomm which supports multiple threads, it realizes the serial communication and GPS data acquisition. Through the GPS information, one may access any location information at any time, and obtain the corresponding vehicle speed and direction information, this method implements the GPS data reception, storage, transfer and text writing. Moreover, the method can also be used in industrial data acquisition, street lamps, electric water real-time monitoring, and it has certain practical application prospect.
