摘要
警用数字集群(PDT)作为我国第一个自主知识产权的集群通信标准,在公安部的大力推动下,全国各个省、市、自治区陆续开展了大规模建设,已基本实现全国联网,形成了全世界最大的一张专用应急通信网络。但由于窄带技术自身的限制,在警务实战的业务场景中,存在警员、车辆定位上图率偏低、机动应用不灵活等问题。文章就这一现状,引进宽带技术重点解决PDT技术在定位、动态重组等应用方面发展的不足,并以某省公安应用为例,对PDT后续的发展应用进行探讨分析。
Under the vigorous promotion of the Ministry of Public Security,Police Digital Trunking(PDT)has been carried out successively with large-scale construction in the whole country,which is the first digital trunking communication standard in our country with independent intellectual property right.It will be the largest emergency communications network in the world as the national network realized and formed.However,due to the limitations of narrowband technology itself,there are problems in the actual police work,such as low locating rate for police officers and vehicles,lack of flexibility in emergency scence.In this paper,we have introduce the broadband technology in order to solving the short usage of PDT technology in the terms of the locations and dynamic reorganization mechanisms.Beyong that,in this paper we used public security of a province as an example to discuss and analyze the subsequent development and application of PDT.
