基于ADSL接入网的实时数据采集系统研究与实现

Research and realization of real-time data acquisition system based on ADSL access network

根据OSI网络的分层原理和ATM网络分层协议模型,提出了基于ADSL接入网的实时数据采集协议模型,从而进一步提出了基于Utopia接口提取数据的数据采集设计方案,并给出了基于FPGA的数据提取控制接口(CTRL-E)的设计与仿真.本系统实现了基于ADSL接入网网路的实时动态数据采集,达到对网路进行实时监控与管理的目的,系统设计可靠,完全符合设计要求.

Based on the OSI delamination principle and the asynchronous transfer mode（ATM） delamination protocol model of the network, the design of data acquisition protocol model which is based on the data acquisition Utopia interface, is put forward. The imitation of the control interface CTRL-E which is based on FPGA is also put forward. The system can supervise the ADSL access network road by realtime dynamic data acquisition. The design of the system is credible and qualified for the designing demand.
