The invention discloses an intelligent 
monitoring system for 
submarine cable running maintenance and relates to a 
monitoring system. At present, 
submarine cable ship anchor damage prevention is greatly influenced by environments and is limited in monitoring range, and a 
false alarm often happens. The 
system comprises a CCTV (
Closed Circuit Television) linkage monitoring subsystem, an AIS (
Automatic Identification System) monitoring subsystem, a 
radar monitoring subsystem, a photoelectricity disturbance alarming subsystem, a 
submarine cable labeling subsystem, a 
wireless voice remote subsystem and an integrated comprehensive monitoring platform, wherein the integrated comprehensive monitoring platform obtains ship information according to the comprehensive treatment of 
monitoring data, and finds ships lingering in a 
submarine cable anchor damage prevention region or 
submarine cable anchor damage accidents in time; and monitoring personnel carry out early warning or command on scene to the ships through the 
wireless voice remote subsystem. According to the technical scheme, the independent subsystems are integrated together, the alarming accuracy is improved, a set of complete, tridimensional, comprehensive and all-
weather monitoring and linkage integrated 
system for 
submarine cable running is established, and the all-weather and effective control aim of 
power transmission submarine cables is achieved.
