The invention discloses an automatic identification and monitoring system for ships in sea area of a 110kv submarine cable. The automatic identification and monitoring system for the ships in sea area of the 110kv submarine cable comprises a platform, a support system and six functional modules, wherein the platform is a unified frame structure platform functioning as a unified plug-in type platform, a unified date model, a unified data exchange bus and a unified data interface; the support system is an AIS (Automatic Identification System) ship dynamic sub-system; the six functional modules are an electronic chart display platform module, a data receive and interface module, a submarine cable area alarming module, a history playback module, a thematic element management module and an alarm video linkage module. According to the automatic identification and monitoring system for ships in the sea area of the 110kv submarine cable, on basis of achieving AIS ship monitoring in the operation region of the submarine cable, all-weather automatic and intelligent monitoring and early-warning to the operation region of the submarine cable is achieved by data intelligent analysis and automatic warning functions, so that accidents caused by that ships anchor in the submarine cable region are basically avoided, operation security of the submarine cable is ensured, and power supply quality of the submarine cable is improved.
