基于TETRA数字集群的无线车载电台开发

Development of Car Radio Based on TETRA Digital Trunking System

基于摩托罗拉TETRA数字集群的MTM700信道机,采用高档8位单片机,内嵌实时操作系统RTOS(NutOS),成功实现了车载无线电台的二次开发。文中首先介绍了无线车载电台的结构组成和主要功能,然后详细介绍了车载电台硬件体系结构与软件设计方法。该车载电台在交付使用后,经过实际运行,表明该型车载电台的开发方案是成功的。该方法简单易行,成本低廉且稳定可靠,在目前国内基于TETRA系统的无线调度集群二次开发中有一定的参考价值。

This paper implements car radio based on MOTOROL＇ TETRA digital trunked of MTM700 channed machine.The car radio uses of 8-bit microprocessor and embedded real time operating system RTDS（NutOS）.This paper introduces the structure of the radio car and main functions and hardware architecture and software design methods of car radio.It is proved that the method was simple,low cost and reliable and successful by used in practice.It is also significative to development of car radio based on TETRA digital trunked in the country.
