基于DSP的多路双向语音光纤传输系统的研制作者:韩信 张晨光 武志刚来源:《电脑知识与技术》2017年第05炭化期 摘要:目前,很多工业现场生产调度均采用无主机通信系统,但因各装置区域覆盖面积大、间距远,直接采用电缆传输时,语音衰耗过大,严重影响通讯质量。为此,该文设计一套以光纤作为传输媒介的多路双向语音光纤传输系统,可解决不同装置区域内各话站间电话用户通信的问题。 关键词: 多路双向; 能量传送器光纤; 复接; 无主机; 以太网

Abstract:At present,防火罩 many industrial field production scheduling are used without host communication system, but due to the large area coverage and the far spacing, directly using cable transmission, sound attenuation is too big防摔玻璃杯, seriously affecting the communication quality. For this reason,栅栏式接线端子 this article designs a set of optical fiber transmissi
on system of multi-channel full-duplex speech by fiber as a transmission medium, which can solve the problem of telephone user communication between stations in different device areas.
