摘　　要：数字对讲机广泛应用于公安、消防、工程建设、物业管理等领域。dPMR是欧洲电信标准协会(ETSI)推出的一种窄带数字对讲机标准。为满足用户对保密数字对讲的需求,文中提出了一种基于dPMR标准的数字加密对讲机方案,介绍了dPMR标准及其技术优势,分析了数字加密技术模型及其关键技术,给出了数字加密对讲机基带电路和射频电路设计方案,分析了系统工作原理,并详细介绍了数据组帧流程和收发过程。Digital radio is widely used in police, fire fighting, engineering construction and estate management etc. The dPMR（digital Private Mobile Radio） is the standard for narrowband digital radio proposed by ETSI（European Telecommunication Standards Institute）. This paper proposes a scheme of digital-encryption radio based on dPMR, thus to meet the user demand of digital-encryption radio. Firstly the advantage of dPMR technique is described, then the digital encryption model and the key technologies are analyzed, both the baseband circuits and radio-frequency circuits designed, and the working principles of the system discussed, and finally the detailed flow of data frame and the process of transceiver are presented.
