基于dPMR标准的数传电台设计

The Design of Radio Modem Based on Standard dPMR

运用嵌入式产品开发方法,从硬件设计和软件开发两方面阐述了采用数字信号的无线数传电台的开发方案。相对于目前国内市场占有率较大的模拟数传电台,数字数传电台频谱利用率更高,具有更好的传输质量和更为可靠的安全性能,未来必将会有良好的应用前景和市场价值。重点介绍了基于dPMR标准数传电台的系统架构与实现、OS任务模块设计以及相关通信协议制定等内容,在诸多方面都有创新的设计应用和实现方法。

This paper uses the methods of the embedded product development, introducing the development plan of the radiomodem by digital signals from two aspects of hardware design and software development. Compared with the analog radio mod-em which shares the larger domestic market for present, the digital radio modem spectrum utilization rate is higher.It has bettertransmission quality and more reliable safety performance, and it must have a good application prospect and market value in thethture. The paper mainly introduces the system framework and implementation, OS task module design as well as related commu-nication protocols of the radio modem based on standard dPMR.It has innovation in many aspects of design and implementationmethod.
