Inductive coupling-based anchoring self-lifting profile monitoring buoy

Abstract

The invention relates to an inductive coupling-based anchoring self-lifting profile monitoring buoy. The conventional monitoring buoy has various deficiencies on communication. The top of a buoy body is provided with an antenna, and the bottom of the buoy body is connected with a counterweight block through a lower bracket and a mooring cable; a buoy body instrument cabin is arranged in the buoy body; a communication transceiving module, a buoy data forwarding module and a coupling signal receiving module are arranged in the buoy body instrument cabin; the communication transceiving module is in signal connection with the buoy data forwarding module; the coupling signal receiving module is in signal connection with the buoy data forwarding module; a coupling signal receiving coil and a coupling signal transmitting coil are sleeved on the mooring cable; the coupling signal receiving coil is in signal connection with a coupling signal transmitting module; the coupling signal transmitting module is in signal connection with an underwater data acquisition and storage module; and the underwater data acquisition and storage module is in signal connection with a profiler sensor. The anchoring self-lifting profile monitoring buoy can realize close-range non-contact wireless transmission in a larger space angle range, and has the advantages of low cost and low power consumption.

Description

technical field [0001] The invention belongs to the technical field of underwater wireless communication, and in particular relates to a mooring self-elevating profile monitoring buoy based on inductive coupling. Background technique [0002] The mooring self-elevating profile monitoring buoy has both the long-term fixed-point characteristics of the mooring buoy and the automatic lifting characteristics of the drifting profile monitoring buoy, and can obtain fixed-point, long-term, high vertical resolution serial vertical profile monitoring data in specific research sea areas. An advanced marine monitoring buoy developed in recent years. This type of buoy usually adopts a two-point mooring design, that is, the upper end is pulled by the buoy, and the lower end is anchored. The profiler moves back and forth between the buoy and the anchorage to collect profile monitoring data. The monitoring data obtained by the profiler is obtained by a certain communication method. After b...

Problems solved by technology

If the communication method between the profiler and the buoy adopts a wired method, the communication distance is constantly changing due to the reciprocating lifting movement of the profiler, which not only makes the design of the transmission line difficult, but also difficult to guarantee the reliability of communication and the safety of the profiler

If the wireless method is adopted, in the underwater wireless communication method, the underwater acoustic communication has a series of advantages such as long transmission distance and high transmission rate, but its cost is too high, and the power consumption is high at the same time. Considering the self-contained power supply of the profiler characteristics, unable to meet long-term observation requirements; underwater laser communication has long communication distance and high transmission rate, but complex structure, high cost, and high communication directionality requirements; underwater LED optical communication has low cost, low power consumption, and long transmission distance It is far away, but there is also the problem of high directionality requirements. If there is no corresponding device to ensure that the probe is aligned within a small range, the communication performance will be greatly reduced or even communication will be interrupted.
