警用数字集群(PDT:Police Digital Trunking)通信系统标准,是由公安部主管部门牵头,由国内行业优秀的系统供应商参与制定,借鉴国际已经发布的标准协议的优点,结合我国公安无线指挥调度通信的需求,推出的一种数字专业无线通信技术标准,为我国公安行业今后数字集群通信系统的发展指明了方向。PDT技术已经在我国很多城市试点使用,取得了很大的成效,在很大程度上改善了公安系统无线通信的质量。今后随着通信技术及相关产业学科技术的进步,PDT技术将越来越成熟,将为我国的公安工作提供良好的技术基础。本文研究了警用数字集群技术发展的由来,分析了PDT系统的技术优点,总结了警用数字集群系统的应用现状,揭示了PDT技术对公安无线通信系统中的重要意义,提出了警用数字集群技术的优化建议。
Police Digital Trunking (PDT) communication system standard is led by the competent department of the Ministry of Public Security and is formulated by excellent system suppliers from domestic industries. Drawing on the advantages of the standard protocols that have been promulgated by the international community and combining with the wireless command dispatch Communication needs, the introduction of a digital professional wireless communications technology standards for the future development of China’s public security industry digital trunking communications system pointed out the direction. PDT technology has been piloted in many cities in our country and has achieved great success, which has greatly improved the quality of public security system wireless communications. In the future, with the progress of discipline and technology in communication technology and related industries, PDT technology will become more and more mature, and will provide a good technical foundation for our country’s public security work. This paper studies the origin of police digital trunking technology development, analyzes the technical merits of PDT system, summarizes the application status of police digital trunking system, reveals the importance of PDT technology in public security wireless communication system, proposes the police digital Optimization of cluster technology.
