目前,山东煤矿微波通信干线已经通过国家验收委员会的验收,现就该干线的技术问题简述如下: 一、技术决策思想1.采用数字微波通信技术,做到一步到位。煤炭工业系统专用通信网总体规划方案中指出:“专用网的新建部分,应尽量采用数字制式。”遵照这一建网原则,山东煤矿微波通信干线采用了数字微波脉码调制技术来建设。南线为二次群电路,新汶局、兖州局、枣庄局各下设一个基群,第四基群通过泰山站D/I分路设备分六路给泰安市有关单位,其余24路给肥城局。东线也是二次群电路,济南至淄博局为一个基群,其余三个基群为淄
At present, the Shandong coal mine microwave communication trunk line has passed the acceptance of the State Commission for Acceptance, the technical problems of the trunk line are summarized as follows: First, the technical decision-making ideas 1. Using digital microwave communication technology, to achieve one step. According to the general planning scheme of the coal industry system-specific communication network, “the new part of the private network should adopt the digital system as much as possible.” In line with this principle of network construction, the Shandong coal mine microwave communication trunk adopts digital microwave pulse code modulation technology. South line for the second group circuit, the Xinwen Bureau, Yanzhou Bureau, Zaozhuang Bureau each set up a base group, the fourth group through the Taishan station D / I equipment sub-six points to the relevant units in Tai’an City, the remaining 24 to Feicheng Bureau. The eastern line is also a secondary group circuit, Jinan to Zibo Bureau as a base group, the other three groups for the Zi
