|
摘要
能够按不同目的的要求实时、准确、可靠、有效地(有QOS保证)传输各类数据信号是人们不断追求的目标,为此,人们提出了下一代(NGN)网络的概念。一种新型网络--宽带综合数据光同步网(WIDOSNet),技术上它基于同步数字体系(SDH)、光纤通信、可编程片上系统(SOPC)等技术,采用高速可编程片上系统组成的多处理器信息处理系统使系统拥有足够的信息处理能力,另外采用全新的动态数据流量调整的概念。
宽带综合数据光同步网主要由网络集中器部分和用户节点部分组成。本课题主要完成用户节点语音通信系统部分的基本功能的研究与设计。结合网络的特点,提出了用户节点的语音通信系统结构,分析了应用于此网络结构和语音通信系统结构的通信协议,并且制作了硬件电路应用此协议,验证了网络结构和语音通信协议的可行性。
本网络的用户节点语音通信系统从硬件结构上可以分为插在节点主板上的语音通信子板和应用于用户终端的语音通信设备。语音子板部分采用SOPC技术,在FPGA上嵌入了32处理器NIOS II,在此基础上应用IP Core技术和嵌入式软件编程进行通信协议的实现。由于本网络的创新性,为了便于测试和灵活应用,用户终端的语音通信设备采用自主设计数字话机,它主要采用AVR单片机和CPLD技术方案实现。
Data signals transmission which according to the different objectives of the requirements of various types of real-time, accurate, reliable and effective (QOS guarantees) is continuing to pursue the goal of the people.To this end, the people put forward the concept of the Next Generation Network(NGN). A new network - Wideband Integrated Data Optical Synchronous Network (WIDOSNet), technically based on the Synchronous Digital Hierarchy (SDH), optical fiber communication, SOPC technology, used high-speed programmable system-on-chip multiprocessor consisting of information processing system allowing the system to have sufficient information processing capability, and a new set of dynamic data flow adjustment concept.
Wideband Integrated Data Optical Synchronous posed mainly by the part of Network Concentrator and the part of the user nodes. The completion of the main topics is the Research and Design for the basic features of user node voice communications system part. the communication protocol applicated to this network structure and the structure of the voice communication system was analyzed, and a hardware circuit application of this agreement, verify the feasibility of the network structure and the voice communication protocol was produced.
The users network nodes voice communications system can be divided into the voice communications baby boards which inserted in nodes motherboard and user terminals for voice communications equipment from the hardware structure. Used SOPC technology, voice communications baby boards embedded a 32 processor NIOS II in the FPGA, communications agreement can be achieved by use of IP Core technology and embedded software programming. As the network of innovative, in order to facilitate testing and flexible application, user terminals voice communications equipment used Digital Telephone which was independently designed.The Digital Telephone was wade mainly by AVR MCU and CPLD technology programme.
