【摘要】：陆地集群无线电（Terrestrial Trunked Radio,TETRA）是当今先进的数字无线集群通信系统之一，它代表了专业无线调度系统的发展方向之一。本论文是基于TETRA的常州轨道交通无线通信调度系统的研究和探讨。 本论文概述了包括系统结构、技术特性、主要特点、工作频段以及组网方式等TETRA基本概念。分析了国内外轨道交通无线通信发展现状，并列举了伦敦地铁、纽约地铁、广州地铁、南京地铁这四个实例简要说明了TETRA系统在轨道交通应用可行性和广泛性。本文着重对常州轨道交通无线通信系统的初步设计进行了阐述，从系统功能、系统方案、系统构成以及系统主要技术指标等分析了常州轨道交通无线通信系统的情况，并就常州轨道交通的实际提出了选择Dimetra IP数字集群系统作为网络技术建议方案，并提升出可实现的二次开发系统方案，突出了二次开发应用程序接口的技术描述。综合全文，总结和展望无线数字集群系统在轨道交通运用的前景。 本论文以常州轨道交通无线调度系统工程为背景，，研究讨论了TETAR数字集群系统在轨道交通中的具体应用。因此，本论文的深入研究不但具有较高的使用价值，同时，也为以后具体的工程项目中提供了可借鉴的方案。
[Abstract]:Terrestrial trunked radio (Terrestrial Trunked Radio,TETRA) is one of the advanced digital wireless trunking communication systems. It represents one of the development directions of professional wireless scheduling systems. This paper is based on the TETRA of Changzhou rail transit wireless communication scheduling system research and discussion. This paper summarizes the basic concepts of TETRA, including system structure, technical characteristics, main features, working frequency band and networking mode. This paper analyzes the present situation of wireless communication of rail transit at home and abroad, and enumerates four examples of London Underground, New York Metro, Guangzhou Metro and Nanjing Metro to illustrate the feasibility and extensibility of the application of TETRA system in rail transit. This paper focuses on the preliminary design of the wireless communication system of Changzhou rail transit, and analyzes the situation of the wireless communication system of Changzhou rail transit from the aspects of system function, system scheme, system composition and main technical index of the system. According to the actual situation of Changzhou rail transit, this paper puts forward the choice of Dimetra IP digital trunking system as the network technical suggestion scheme, and improves the realizable secondary development system scheme, and highlights the technical description of the secondary development application program interface. This paper summarizes and prospects the application of wireless digital trunking system in rail transit. In this paper, the application of TETAR digital trunking system in rail transit is discussed based on the project of Changzhou rail transit wireless dispatching system. Therefore, the in-depth study of this paper not only has a higher use value, but also provides a reference for future specific projects.
