应用Delphi实现GPS接收机与MapInfo之间的通讯

Communication technique between GPS receiver and MapInfo Based on Delphi

本文讨论了Windows环境下GPS接收机与地理信息软件MapInfo之间的通讯原理,利用Delphi中的面向对象、多线程处理技术以及Windows中的动态数据交换(DDE)技术,编写了通讯服务程序,实现了GPS接收机的数据采集和处理,以及与计算机之间的通讯。

This paper discusses the communication principle between GPS receiver and GIS software-Maplnfo in the windows environment, compiles the communication program through the object-orientation, multi-thread techniques of Delphi and Windows Dynamic Data Exchange（DDE） technique, realizes GPS receiver data collection , management and communication with computer.
