DETAILED DESCRIPTION

[0030] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0032] The following discussion provides multiple embodiments of the present invention. Although each embodiment represents a single combination of the application, different embodiments of the present invention can be replaced or combined, so the present invention can also be considered to include all possible combinations of the same and / or different embodiments described. Thus, if one embodiment includes A, B, C, and another embodiment includes a combination of B and D, then the present invention should also be considered to include embodiments containing one or more of A, B, C, D and all other possible combinations, even though the embodiment may not be clearly described in the following text.

[0033] Figure 7 This is a schematic diagram of the application of an ocean drifting buoy system based on communication satellite communication. This application is a drifting buoy 1#...N# launched for the ocean drifting buoy system for ocean research and application, which is specially designed for unattended real-time measurement of ocean environmental parameters in the ocean. The device tracks ocean currents on the surface of the sea, measures the dynamic environmental parameters of the ocean surface, and sends them back to the land-based data collection center via communication satellites. The ocean drifting buoy based on communication satellites can collect and transmit the current location information and ocean environmental parameters of the reported buoy in real time through multi-system multi-frequency high-performance SoC chips, Beidou / GPS combined positioning, and Beidou / Iridium short message communications.

[0034] In the present invention, Figure 1 and Figure 2 As shown, an embodiment of the first aspect of the present invention provides a floating ball assembly 100 of a drifting buoy, including: a first floating ball 10, a second floating ball 20, a communication module 30, a battery pack 40, a sensor 50, and a control circuit 60.

[0035] The first float 10 is connected to the second float 20 directly or through a connecting piece.

[0036] The communication module 30 communicates with the satellite navigation system or the global positioning system through the antenna 70 to transmit the location information. The communication module 30 communicates with the satellite navigation system or the artificial satellite through the antenna 70 to transmit the measurement data, so as to facilitate the real-time understanding of the data detected by the drifting buoy.

[0037] The communication module 30 can autonomously report location information: support autonomous reporting of location information;

[0038] The location information can be set to communicate with the Beidou satellite every 1 hour, every half hour, etc., send the location information, and send the time, longitude and latitude information to the satellite.

[0039] Communication system performance (taking Beidou as an example, it can be replaced by Iridium or Argos)

[0040] Beidou satellite communication performance parameters

[0041]

[0042] The sensor 50 may include a seawater temperature sensor, a seawater salinity sensor, a wave measurement sensor, or multiple types of sensors may be installed. Those skilled in the art should select the appropriate sensor for the specific situation.

[0043] like Figure 1 and Figure 2 As shown, the first float 10 is connected to the second float 20 , and the communication module 30 , the battery pack 40 , the sensor 50 , and the control circuit 60 are disposed in the first float 10 .

[0044] The sensor 50 is connected to the control circuit 60 , the control circuit 60 is connected to the communication module 30 , and the battery pack 40 supplies power to the communication module 30 , the sensor 50 , and the control circuit 60 , respectively.

[0045] In the float assembly 100 provided by the present invention, the second float 20 is located in the sea water, and at most half of the first float 10 is located in the sea water. The buoyancy of the two floats is relatively large. On the one hand, the stability of the drifting buoy in the sea water can be ensured, and damage to the electrical components in the float assembly 100 caused by large currents can be avoided, thereby ensuring the service life of the electrical components, that is, improving the reliability of the product; on the other hand, the drifting buoy can carry more detection elements, so that more sea water data can be detected and obtained, which greatly expands the function of the drifting buoy, thereby expanding the scope of use of the drifting buoy and increasing the market competitiveness of the product.

[0046] The control circuit 60 is used to control the mounted sensor 50 to measure data, send instructions to the sensor 50 (pre-set instructions, such as collecting data every 20 minutes), and transmit the information to the communication module 30 after digital processing by the control circuit 60.

[0047] like Figure 2 As shown, in one embodiment of the present invention, the float assembly 100 further includes a magnetic switch 90, which ensures that the drifting buoy is in a "silent" state (not powered) before the drifting buoy is deployed. When deployed, the magnetic switch 90 is turned on, the entire drifting buoy is powered on, and starts working.

[0048] like Figure 3 As shown, in one embodiment of the present invention, the first float 10 includes a first hemisphere 11 and a second hemisphere 12 , and the first hemisphere 11 and the second hemisphere 12 are fixedly connected via a first locking assembly 80 .

[0049] The first locking assembly 80 includes a first locking buckle 81 , a first locking member 82 and a first sensing member 83 .

[0050] The first locking buckle 81 is disposed on the first hemisphere 11 .

[0051] The first locking member 82 is disposed on the second hemisphere 12 , and the first locking member 82 is locked with the first locking buckle 81 to fix the first hemisphere 11 and the second hemisphere 12 together.

[0052] The first sensing element 83 is connected to the first locking element 82 and is used to control the first locking element 82 to separate from the second locking element according to the first signal received.

[0053] In this embodiment, the first locking assembly 80 can be an electromagnetic structure, the first lock buckle 81 is a magnet or iron, and the first locking piece 82 is an electromagnet. The electromagnet is always in a powered state, and the first lock buckle 81 and the first locking piece 82 are always in a locked state. The first signal is sent to the first sensing component 83 through the controller, and the electromagnet is powered off to separate the first lock buckle 81 from the first locking piece 82. This avoids the probability of the first float 10 being opened by external force, thereby ensuring the reliability of the float assembly 100.

[0054] In one embodiment of the present invention, a backup battery pack is disposed in the second float.

[0055] In this embodiment, the provision of a backup battery pack increases the power capacity of the float assembly. When the battery pack is exhausted or damaged and cannot provide electricity, the backup battery pack can continue to provide electricity, which can extend the battery life of the drifting buoy, thereby expanding the use range of the drifting buoy and increasing the product time and data measurement range.

[0056] In one embodiment of the present invention, a backup communication module, a backup sensor, and a backup control circuit are disposed in the second float.

[0057] In this embodiment, when any one of the communication module, sensor, and control circuit fails, the backup communication module, backup sensor, and backup control circuit can be started immediately, so that the drifting buoy can be used for a longer time, thereby expanding the use range of the drifting buoy and increasing the product time and data measurement range.

[0058] In one embodiment of the present invention, the second float includes a third hemisphere and a fourth hemisphere, and the third hemisphere and the fourth hemisphere are fixedly connected via a second locking assembly.

[0059] The second locking assembly includes: a second lock buckle, a second locking member and a second sensing member.

[0060] The second lock buckle is arranged on the third hemisphere.

[0061] The second locking piece is arranged on the fourth hemisphere, and the second locking piece is locked with the second locking buckle to fix the second hemisphere to the second hemisphere.

[0062] The second sensing component is connected to the second locking component, and is used for controlling the second locking component to separate from the second locking component according to the received second signal.

[0063] In this embodiment, the second locking assembly can be an electromagnetic structure, the second lock is a magnet or iron, and the second locking piece is an electromagnet. The electromagnet is always in a powered state, and the second lock and the second locking piece are always in a locked state. The second signal is sent to the second sensor component through the controller, and the electromagnet is powered off to separate the second lock from the second locking piece. This avoids the probability of the second float being opened by external force, thereby ensuring the reliability of the float assembly.

[0064] like Figure 4 As shown, a second embodiment of the present invention provides a drifting buoy, including: a float assembly 100, a connecting chain 200 and a hydrodynamic system 300.

[0065] The float assembly 100 is any of the float assemblies 100 described above.

[0066] One end of the connecting chain 200 is connected to the second float 20 of the float assembly 100 .

[0067] The water power system 300 is connected to the other end of the connection chain 200 .

[0068] The drifting buoy provided by the present invention has a float assembly 100 with two floats. The two floats have relatively large buoyancy. On the one hand, the stability of the drifting buoy in the seawater can be ensured, and damage to the electrical components in the drifting buoy due to large ocean currents can be avoided, thereby ensuring the service life of the electrical components, that is, improving the reliability of the product. On the other hand, the drifting buoy can carry more detection elements, so that more seawater data can be detected and obtained, which greatly expands the function of the drifting buoy, thereby expanding the scope of use of the drifting buoy and increasing the market competitiveness of the product.

[0069] like Figure 5 As shown, in one embodiment of the present invention, a plurality of measuring sensors 400 are disposed on the connecting chain 200 along the length direction of the connecting chain 200 ; the plurality of measuring sensors 400 are connected to the control circuit 60 of the float assembly 100 .

[0070] In this embodiment, the connection chain 200 can use a cable or a plastic-coated load-bearing communication cable to connect the system and transmit signals. The measuring sensor 400 is determined according to user needs, and can be equipped with sensors such as water temperature or temperature and salinity, and the number of sensors is determined according to user needs. The connection chain 200 is very thick and has communication lines inside. It is also used as a communication cable. The connection chain 200 integrates no less than 10 measuring sensors 400 on a load-bearing communication cable of a certain length (more than 10 meters), and adopts addressing and single bus communication methods to realize the observation and transmission of temperature and salinity of multiple water layers, thereby expanding the scope of use of the drifting buoy and increasing the market competitiveness of the product.

[0071] like Figure 6 As shown, in one embodiment of the present invention, a water power system 300 comprises: a bracket and an outer cover. The outer cover is arranged on the bracket, and a plurality of through holes 301 are arranged on the outer cover.

[0072] In this embodiment, the arrangement of multiple through holes 301 on the outer cover can ensure that the hydrodynamic system 300 floats with the flow, while preventing the hydrodynamic system 300 from being subjected to excessive force from the flow, causing excessive deformation of the hydrodynamic system 300.

[0073] In one embodiment of the present invention, through holes 301 are arranged on the symmetrical side walls of the outer cover, and two symmetrically arranged through holes 301 form a channel.

[0074] In this embodiment, two symmetrically arranged through holes 301 form a channel for the ocean current to pass through, so that the hydrodynamic system 300 can move according to the direction of the ocean current and can better detect various parameters of the seawater.

[0075] In one embodiment of the present invention, the axes of adjacent channels are arranged to intersect with each other.

[0076] In this embodiment, the axes of adjacent channels are arranged to intersect, and channels for ocean currents to pass through in multiple directions can be formed, so that the hydrodynamic system 300 can adapt to ocean currents in different directions and can better detect various parameters of seawater. The axes of adjacent channels can be at any angle.
