DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0026] See also Figure 1-5 The present invention provides a technical solution: a communication buoy based on a MESH self-organizing network, comprising a damping float 1, a float box 2 is fixedly connected to the top of the damping float 1, a containing shell 3 is fixedly connected to the top of the containing shell 3, an elevated frame 4 is fixedly connected to the top of the containing shell 3, and the damping float 1 has a large mass, which is convenient for sinking the center of gravity.

[0027] A receiving groove 13 is provided inside the damping float 1, and a first balancing ball 15 is arranged inside the receiving groove 13. An upper connecting plate 27 is fixedly connected to the top of the inner wall of the receiving groove 13, and an upper spring 14 is fixedly connected between the lower surface of the upper connecting plate 27 and the top of the first balancing ball 15. A connecting rod structure is provided at the bottom of the first balancing ball 15.

[0028] A gravity block 18 is disposed inside the accommodating shell 3 , a connecting carrier 19 is fixedly connected to the surface of the gravity block 18 , and a plurality of connecting ropes 20 are fixedly connected between the side wall of the connecting carrier 19 and the inner wall surface of the accommodating shell 3 .

[0029] The top of the elevated frame 4 is connected to a base 21, a ball seat 23 is provided inside the base 21, the top of the ball seat 23 is fixedly connected to the antenna 6, the bottom of the ball seat 23 is vertically fixedly connected to a vertical rod 24, the bottom end of the vertical rod 24 is movably extended to the inside of the elevated frame 4, and is fixedly connected to a second balancing ball 25.

[0030] The upper spring 14 and the first balancing ball 15 can damp the up and down floating of the buoy box 2, assist in adjusting the stability of the buoy, and cooperate with the connection of the gravity block 18, the connecting carrier 19 and the connecting rope 20 to damp the longitudinal shaking of the accommodating shell 3, better assist in adjusting the stability of the damping float 1, thereby reducing the shaking amplitude of the communication buoy affected by the external environment and improving the stability of the communication buoy placed in the ocean.

[0031] The connection between the second balancing ball 25 and the vertical rod 24 causes the ball seat 23 to be displaced inside the hemispherical groove 22 during the shaking of the communication buoy, dynamically adjusting the posture of the ball seat 23 to better maintain the vertical state of the antenna 6, reduce the amplitude of the bumps and shaking of the damping float 1 caused by wind and waves, reduce the impact of wind and waves on the antenna 6, and ensure the communication quality.

[0032] The vertically placed antenna 6 can radiate signals more effectively in all directions, forming a more uniform radiation field. In contrast, if the antenna 6 is placed horizontally or directionally, the signal may be weak in some directions and too strong in other directions, thereby affecting the overall signal coverage.

[0033] Keeping antenna 6 in a vertical state can reduce mutual interference with other antennas 6 or objects. Vertical placement helps reduce interference and improve communication stability. The vertically placed antenna 6 is more in line with its propagation characteristics. Therefore, the vertically placed communication buoy antenna 6 is more conducive to signal transmission and reception.

[0034] Keeping the antenna 6 in a vertical state can more effectively receive signals from different directions, thereby increasing the reliability and stability of communication. In complex environments such as the ocean, communication buoys need to face interference from natural factors such as various weather and waves. The vertically placed antenna 6 helps to improve communication efficiency and ensure accurate data transmission.

[0048] The master receives local data, processes it at the application layer, and then sends it down. After being encapsulated by the protocol, it is transmitted through the MESH network.

[0049] When the MESH module acts as a relay node, the data of other nodes does not need to be processed locally, but is directly forwarded transparently; the final data is aggregated to the gateway node;
