Wireless expansion system applied to deep sea seabed observation

Abstract

The invention discloses a wireless expansion system applied to deep sea seabed observation, which comprises a deep sea advanced anchoring device arranged at a fixed observation node in deep sea and a plurality of self-contained deep sea subsurface buoy devices, and is characterized in that a mobile shore base is connected with a seabed main base station through a main submarine cable; the seabed main base station, the deep sea advanced anchoring device, an autonomous underwater robot and the plurality of self-contained deep sea subsurface buoy devices are provided with respective underwater acoustic communication machines to form an interconnected underwater acoustic WI-FI network; the autonomous underwater robot is used for obtaining mobile observation data and feeding back the mobile observation data to the seabed main base station; the deep sea advanced anchoring device is used for acquiring observation data of the fixed observation node and feeding back the observation data to the seabed main base station; the self-contained deep sea subsurface buoy devices are used for acquiring observation data of the fixed observation node and feeding back the observation data to the seabed main base station; and the seabed main base station is used for gathering all observation data and uploading the observation data to a mobile shore base through a seabed cable observation network or a high-strength photoelectric composite submarine optical cable. The system solves the technical problems that a traditional cable seabed observation system has a limited observation range and cannot be flexibly deployed, and a main cable network, a wireless fixed network and a wireless mobile network cannot be organically combined, and cannot realize real-time dynamic tracking observation.

Description

technical field [0001] The invention belongs to the technical field of underwater information network, and in particular relates to a wireless expansion system applied to deep sea bottom observation. Background technique [0002] The seabed scientific observation network is the third earth science observation platform established by mankind after ground and sea surface observation and aerial telemetry and remote sensing. It can realize large-scale, all-weather, comprehensive, Long-term, continuous, real-time high-resolution and high-precision observations provide support for multidisciplinary development of oceanography, marine security, marine energy and resource development, marine disaster warning and forecasting, marine environmental monitoring and protection, marine engineering experiments, marine science education, etc. The national marine strategy needs to provide strong support. [0003] The traditional cabled submarine observation system mainly relies on the submar...
