摘要
介绍了上海轨道交通公安无线通信系统的现状。随着无线通信技术和需求的发展,上海公安建设了350 MHz数字集群无线通信系统,并对应提出了地铁公安无线通信的数字化建设。在研究交换中心组网方式的基础上,提出了地铁公安数字集群系统建设的方案,讨论了系统组成和重要接口。
The current situation of radio communication system in Shanghai metro police is introduced. With the development of radio technology and increasing requirements, Shanghai Public Security Bureau constructed a 350 MHz digital trunked radio communication system and proposed the digital construction for metro police radio system. Based on the network mode of mobile switching center,a scheme of building police digital trunked radio com- munication system in metro is put forward, the component and important interfaces of the system are discussed.
