Description

Technical Field

[0001] This utility model relates to the field of buoy status monitoring systems, and in particular to a buoy status monitoring system. Background Technology

[0002] Marine data buoys are currently the main means of unmanned monitoring of the marine environment in my country. In recent years, they have been widely used in operations and have played an important role in marine environmental forecasting, disaster prevention and mitigation early warning, and marine resource development in my country.

[0003] When exposed to harsh environments for extended periods, buoys themselves will gradually develop various problems: passing ships may scrape over or even collide with the buoy, causing damage or even destruction to the buoy and its equipment; once-in-a-century typhoons, with their wind force and waves exceeding the safety factor of the buoy's design, will damage the buoy and its various equipment. Utility Model Content

[0004] The purpose of this invention is to provide a buoy status monitoring system, which aims to solve the problem of monitoring buoy damage.

[0005] This utility model provides a buoy status monitoring system, including: Host computer, pulse generator, light source module, multiple optical fibers, multi-channel splitter, spectrum modulation module and signal processor; The host computer is connected to the pulse generator, the pulse generator is connected to the light source module, the light source module is connected to the multi-channel beam splitter, the multi-channel beam splitter is connected to multiple optical fibers, the multiple optical fibers are attached and fixed to the device to be detected in the buoy, the spectral demodulation module is connected to the multi-channel beam splitter, the spectral demodulation module is connected to the signal processor, and the signal processor is connected to the host computer.

[0006] By employing this embodiment of the invention, buoy damage monitoring is achieved through optical path feedback and the conversion of optical pulse signals into electrical signals, which are then sent to the host computer.

[0010] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0011] System Implementation Examples According to an embodiment of the present invention, a buoy status monitoring system is provided. Figure 1 This is a schematic diagram of a buoy status monitoring system according to an embodiment of the present invention, as shown below. Figure 1 As shown, it specifically includes: A buoy status monitoring system, comprising, Host computer, pulse generator, light source module, multiple optical fibers, multi-channel splitter, spectrum modulation module and signal processor; The multi-channel beam splitter is connected to multiple optical fibers, which are then bonded and fixed to the buoy detection device. The host computer is connected to the pulse generator, which is connected to the light source module. The light source module is connected to the multi-channel beam splitter, the spectral demodulation module is connected to the multi-channel beam splitter, the spectral demodulation module is connected to the signal processor, the signal processor is connected to the host computer, and the host computer is connected to the Internet.

[0012] The host computer sends an electrical signal to the pulse generator, which generates an electrical pulse based on the electrical signal. The light source module receives the electrical pulse and generates an optical pulse signal. The multi-channel splitter divides the optical pulse signal into optical pulse signals of different frequencies and transmits them to multiple optical fibers. Optical splitters are key components in optical fiber communication, used to distribute optical signals to multiple channels (splitting) or combine multiple signals (combining).

[0013] In this embodiment of the utility model, the multi-channel beam splitter adopts a fused taper type beam splitter; its features are: it is manufactured by fused taper process, which results in low cost and suitability for small-scale beam splitting.

[0014] When the state of a certain position of the buoy to be detected changes, and the optical fiber is affected by external mechanical vibration, the position to be detected or / and the optical fiber at the position to be detected will be damaged. The physical structure or transmission characteristics of the optical fiber will change instantaneously, causing some optical pulse signals to be reflected back. The multi-channel splitter receives the abnormal optical pulse signals back from one or more optical fibers, combines them, and sends them to the spectral demodulation module. The spectral demodulation module demodulates the combined abnormal back-transmitted optical pulse signals and sends the abnormal electrical signal of the damaged position to the signal processor. The signal processor DSP amplifies the abnormal signal of the damaged position and sends it to the host computer. The host computer receives the abnormal signal and issues a warning message for the damaged position.

[0015] In this embodiment of the utility model, the spectral demodulation module uses an SM125 fiber grating sensor demodulator. The buoy testing equipment includes: buoy sensors, buoy solar panels, and other key buoy locations.

[0016] Other critical locations for buoys include: the outer edge of the buoy deck, the axial side of the buoy mast tube, and the guardrails of the upper platform of the buoy, which are prone to serious collisions.

[0017] In this embodiment of the invention, the host computer uploads the buoy damage warning information to the Internet to facilitate monitoring by buoy monitoring personnel.

[0018] In another embodiment of this utility model, the host computer uploads the buoy damage warning information to the satellite, and the satellite sends the information to the ground base station, which facilitates the monitoring by buoy monitoring personnel.

[0019] In this embodiment of the invention, the system is installed inside the float.

[0020] The beneficial effects of this utility model embodiment are as follows: In the event of a damaged buoy, the location of the damage can be identified promptly, and the buoy's status can be monitored via the internet; It saves a lot of manpower, material resources and time costs, and has a simple structural design and is easy to produce and process.

[0021] Easy to install, suitable for long-term use, installed inside the float for corrosion resistance, uses optical signals at the signal acquisition end for electromagnetic interference resistance, highly integrated, and easy to maintain.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions to the technical solutions of the embodiments of this utility model do not cause the essence of the corresponding technical solutions to deviate from the scope of this solution.
