基建工程现场信息网络传输关键技术研究

结合吉林省内基建工作业务现状,围绕施工作业现场,以一线业务管理人员赋能为目标,提出采用基于长期演进(LTE)节点模式的工程现场通信盲区自建无线网。经过工程现场实测,在江堤附近通视条件下,承载单路1080P视频传输的极限距离为150km;在山林聚集区,经过山区阻隔的语音通信和视频传输距离约为2.5km,满足基建线路工程的通信条件,实现以自动化手段采集基建现场作业信息,减轻现场作业管理人员工作负担的同时,为上端的平台层和应用层提供完整、及时、准确的数据链路支撑。

Research on Transmission Key Technology of Power Construction Project On-site Information Network

Combining the present situation of construction work in Jilin Province,focus on the construction site and target to enable the first-line management staff,the paper proposed to construct self-built wireless network based on LTE node model for communication blind area.After field measurements,the limit distance for carrying a single 1080Pvideo transmission is 150km under lineof-sight condition in the vicinity of bank,the distance of voice communication and video transmission that passed through the mountains is approximately 2.5km in mountain area,which satisfied communication conditions for power construction line project and collected information on construction site operations by automated means.It would reduce the workload of the first-line management staff and provide complete、timely and accurate data link support for upper platform layer and application layer。
