Abstract

Submarine optical fiber cable construction consists of marine survey, PLGR(Pre Lay Grapnel Run), shore-end-work, laying order. PLGR is the work process which removes the oceanic contaminations(ropes, wires, nets etc) in the route before laying the submarine optical cable. This PLGR is work to ease the cable lay safely in seabed, improve the performance af Plough and ROV(Remotely-Operated Vehicle) laying work, and protect laying equipment. This paper presents the design and implementation of real-time monitoring system for PLGR work in submarine optical fiber cable construction enterprise. In this paper, we designe overall real-time monitoring system. For this purpose, the modules such as serial multi port communication module, communication module, real-time processing module, environment configuration module, real-time graph and a printout module are designed and implemented. For the validity evaluation of this paper, serial multi port communication module, data parsing, realtime graph output are implemented and tested.
