Research on Comprehensive Communication Carrying Network for Construction Period of Railways in Challenging Mountainous Areas
The mobile communication infrastructure along railways in challenging mountainous areas is predominantly insufficient.It is essential to address voice,data,video surveillance,and emergency communication service needs during railway construction in these areas.The study delves into analyzing and organizing infrastructure monitoring services alongside railways in challenging mountainous areas.It explores the necessary bandwidths for voice,data,and video surveillance during construction.Tailored construction communication solutions are proposed based on diverse communication network coverage situations and varying service carrying requirements at construction sites.A comprehensive communication carrying platform covering the entire railway lines during construction period is developed,utilizing network convergence to facilitate transmission for infrastructure monitoring,voice,video,and emergency services.Additionally,the study contemplates the combination of permanent and temporary works of communication carrying networks built during construction for operation purposes,proposing an approach that combines permanent and temporary works.
