摘要
在分析研究煤矿井下综合业务传输信源与信道特征的基础上 ,提出了一种适合煤矿井下使用的环形互连网结构———光纤混合接入网 .各子系统的信息均以接入方式进入网络传输 .同时对网络中的简化路由算法、接入方式、网络传输协议等进行了研究 .用DSP开发系统进行了实验 ,在EIA - 2 32层面上实现井下各种不同传输速率的监测监控系统和数字话音信号的综合传输 ,结果表明 ,提出的光纤混合接入网适合煤矿井下信息综合传输的要求 ,网络协议设计合理 .
Based on the analysis and study of information sources and characteristics of transmission channels in underground integrated service digital network (UISDN) an interconnecting network structure called fiber hybrid access network (FHAN) was presented Any information from monitoring subsystems should access into and transmit in FHAN network The simplified algorithm, access methods and communication protocols were also discussed The experiments using DSP developing system to link different monitoring systems with their own rates and digital voice in EIA-232 layer were tested The results indicated that HFAN and its protocols were suitable for the transmission of UISDN
