城市车辆与日俱增，交日益混乱，为了便于公安部门对交通的管理和武警部队作战指挥的需要，也为了行车的便利，大型城市越来越需要一个智能化的车辆导航系统（ＩＮＳ）。本文以我们为武警开发的科研项目为背景，提出了一个智能导航系统的结构设计，其中包括ＧＩＳ、ＧＰＳ、数字蜂窝通信技术和导航控制网等部分，本文还展望了ＩＮＳ在多媒体通信、语音识别、自动控制等方面的进一步发展。 In order to facilitate the management of traffic and the need of Armed Police Corps to conduct combat command by the public security department, as well as increasing the number of vehicles in urban areas, large-scale cities are increasingly demanding an Intelligent Vehicle Navigation System (INS). Based on the research project we developed for Armed Police, this paper proposes a structural design of intelligent navigation system, including GIS, GPS, digital cellular communication technology and navigation and control network. The paper also looks into INS’s application in multimedia communications, speech recognition , Automatic control and other aspects of further development.
