Description

Technical Field

[0001] The invention belongs to the technical field of electrical components, and specifically relates to changing the direction of radiation waves of an antenna, and more particularly to a multi-stage marine communication antenna and a communication method. Background Art

[0002] When small marine navigation equipment is operating on the sea, the fluctuation of waves will cause the antenna of the navigation equipment to fluctuate and deflect, thereby changing the direction of the electromagnetic waves emitted by the antenna of the navigation equipment, thereby weakening the communication signal of the navigation equipment received by the distant pilot ship.

[0003] In the related art, the problem of weakened communication signals is solved by increasing the antenna output power, which results in increased energy consumption of the navigation equipment. Therefore, a larger capacity battery is required, which results in an increase in the weight of the navigation equipment, thereby increasing the size of the navigation equipment, which cannot meet the demand for miniaturization of the navigation equipment.

DETAILED DESCRIPTION

[0063] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0064] Research has found that due to the fluctuation of waves, the antenna of the navigation equipment will fluctuate and deflect, thereby changing the direction of the electromagnetic waves emitted by the antenna of the navigation equipment, thereby weakening the communication signal of the navigation equipment received by the distant pilot ship.

[0065] Based on the above research, the disclosed embodiment provides a multi-stage marine communication antenna and communication method. The first signal from different directions is received by the signal receiving column, and the direction of the first signal is determined by the controller. When the antenna body fluctuates and rotates, the direction of the second signal is adjusted in real time, and the signal transmitter in the corresponding direction is used to send the second signal, thereby ensuring the signal strength.

[0066] The defects existing in the above solutions are the results obtained by the inventor after practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed by the present invention in this article for the above problems should be the contributions made by the inventor to the present invention during the disclosure process.

[0067] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0068] See also Figure 1 , Figure 1The top view of a multi-stage marine communication antenna is shown, which includes: an antenna body 100, a signal receiving column 200 and a plurality of signal transmitters 300; the signal receiving column 200 is arranged through the antenna body 100; a plurality of signal transmitters 300 are arranged on the side wall of the antenna body 100 in a circular array; a controller is arranged in the antenna body 100; the signal receiving column 200 is suitable for receiving first signals in different directions and sending them to the controller; the controller is suitable for controlling the signal transmitter 300 in the corresponding direction to send a second signal according to the direction of the received first signal. The first signals in different directions are received by the signal receiving column 200, and the direction of the first signal is determined by the controller. When the antenna body 100 fluctuates and rotates, the direction of sending the second signal is adjusted in real time, and the signal transmitter 300 in the corresponding direction is used to send the second signal, thereby ensuring the signal strength.

[0069] See also Figure 1 and Figure 2 In some embodiments, the signal receiving column 200 includes: a column 210 and a plurality of signal receiving elements 220 distributed at equal intervals along the side wall of the column 210; the plurality of signal receiving elements 220 are electrically connected to the controller respectively; the controller is configured to compare the signal strength of the same first signal received by the plurality of signal receiving elements 220, so as to determine the direction of the received first signal. By evenly distributing the plurality of signal receiving elements 220 in a circular array on the side wall of the column 210, the direction of the emission of the first signal of the current signal receiving element 220 can be determined by determining the difference in the received signal strength.

[0070] In a specific implementation, the number of signal receiving elements 220 is N, and the angle difference between the N signal receiving elements 220 is 360 / N. One of the signal receiving elements 220 is set to 0°, and then the angle is defined for each signal receiving element 220 in sequence. The transmission direction of the first signal is the angle of the signal receiver where the first signal with the strongest signal strength is located.

[0071] See also Figure 3 In some embodiments, the signal receiving member 220 includes a connecting plate 221 and a receiving panel 222 ; the receiving panel 222 is fixed to the column 210 through the connecting plate 221 . Figure 3 The dotted line in the figure is the transmission path of part of the signal, and the arrow is the transmission direction of the signal.

[0072] See also Figure 4In order to reduce signal loss, in a preferred embodiment, the receiving panel 222 is an arc surface. By setting the receiving panel 222 as an arc surface, the signal range received by the signal receiving element 220 different from the first signal transmission direction is reduced, thereby reducing the signal strength of the received first signal, thereby improving the difference of the first signal received by the controller, facilitating the controller to distinguish the signal strength, and improving the recognition accuracy of the first signal direction.

[0073] Please continue reading Figure 3 In a preferred embodiment, both sides of the connecting plate 221 are provided with an absorbing layer 240; the connecting plates 221 of two adjacent signal receiving elements 220 form an absorbing region 230. By providing the absorbing region 230, the electromagnetic waves emitted to the arc surfaces of the two adjacent signal receiving elements 220 are absorbed, thereby reducing the reflection of the electromagnetic waves and reducing the interference to the signals received by the signal receiving elements 220.

[0074] Specifically, the wave absorbing layer 240 is made of metal powder or metal coating, and absorbs electromagnetic waves through resonance effect.

[0075] Since the sea surface is not calm in most cases, when waves appear on the sea surface, the antenna body 100 will rise and fall with the waves, thereby causing the transmission angle of the signal transmitter 300 to change, thereby causing the intensity of the second signal received by the signal receiving end of the second signal to change.

[0076] Please participate Figure 3 The signal transmitter 300 includes: a transmitter body 310, a rotating shaft 320 and a brushless motor; the transmitter body 310 is rotatably connected to the antenna body 100 via the rotating shaft 320; the brushless motor is built into the antenna body 100, and is suitable for driving the rotating shaft 320 to rotate, thereby driving the transmitter body 310 to rotate, thereby changing the signal transmission angle of the transmitter body 310.

[0077] See also Figure 5 In order to detect whether the antenna body 100 is currently in the rising section or the falling section of the wave, in a preferred embodiment, the controller is also configured to receive angle information fed back by the Hall sensor of the brushless motor, and is suitable for judging whether the current antenna body 100 is in the rising section or the falling section of the wave based on the received angle information. When the current antenna body 100 is in the rising section, the corresponding signal transmitter 300 is controlled to increase the output power, and the rotating shaft 320 is controlled to rotate for reset. When the current antenna body 100 is in the falling section, the rotating shaft 320 is controlled to reset, and the corresponding signal transmitter 300 is controlled to stop working.

[0078] Specifically, the step of judging whether the current antenna body 100 is in the rising section or the falling section of the wave based on the received angle information is, that is, when the received angle information increases, it indicates that the current antenna body 100 is in the rising section of the wave; when the received angle information decreases, it indicates that the current antenna body 100 is in the falling section of the wave.

[0079] When the antenna body 100 changes from a calm state to a rising stage following the waves, the signal transmitter 300 will deviate along the first direction F1 under the action of inertia. Similarly, when the antenna body 100 changes from a calm state to a falling stage following the waves, the signal transmitter 300 will deviate along the second direction F2 under the action of inertia. When the Hall sensor detects that the rotating shaft 320 is deflected, it is reset according to the detected angle information, so as not to affect the normal use of the signal transmitter 300.

[0080] Specifically, the change value of the angle information when the brushless motor drives the rotating shaft 320 to move toward the first direction F1 is defined as an increase in the angle information, and the change value of the angle information when the brushless motor drives the rotating shaft 320 to move toward the second direction F2 is defined as a decrease in the angle information.

[0081] When the antenna body 100 is close to the obstacle 400 (for example, the side plate of a ship), the side plate will reflect the second signal, so that the second signal sent by the signal transmitter 300 cannot be received by the signal receiving end. To reduce the occurrence of such a situation, please refer to Figure 6 In some embodiments, the receiving panel 222 includes an upper panel 2221 and a lower panel 2222; the upper panel 2221 and the lower panel 2222 are respectively arranged above and below the antenna body 100; the controller is further configured to control the brushless motor to drive the rotating shaft 320 to rotate when the difference in the strength values ​​of the signals received from the upper panel 2221 and the lower panel 2222 of the same signal receiving element 220 is greater than a preset value, thereby driving the transmitter body 310 to rotate, thereby changing the signal transmission angle of the transmitter body 310, until the difference in the strength values ​​of the signals from the upper panel 2221 and the lower panel 2222 is less than or equal to the preset value. By changing the angle of the transmitter body 310, the transmission angle of the second signal is adjusted so that the second signal skips the obstacle 400, thereby not affecting the normal operation of the antenna.

[0082] in, Figure 6 The dotted line in the figure is the transmission path of part of the signal, and the arrow is the transmission direction of the signal.

[0083] At least one embodiment further provides a communication method, which is applied to a marine life-saving system; the marine life-saving system includes a pilot ship, intelligent rescue equipment and a floating beacon; the intelligent rescue equipment is provided with a multi-stage marine communication antenna as described above.

[0084] The communication method includes: the floating beacon sends a distress command after being activated when it falls into the water; the intelligent terminal of the pilot ship receives the distress command and sends a first signal to the multi-stage marine communication antenna of the intelligent rescue equipment; the intelligent rescue equipment moves toward the floating beacon that falls into the water according to the received first signal, and is also suitable for controlling the signal transmitter 300 in the corresponding direction to send a second signal according to the direction of the received first signal; the pilot ship is suitable for real-time monitoring of the current position and rescue results of the intelligent rescue equipment according to the received second signal. By installing a multi-stage marine communication antenna on the intelligent rescue equipment, the first signals in different directions are received through the signal receiving column 200, and the direction of the first signal is determined by the controller. When the antenna body 100 fluctuates and rotates, the direction of the second signal is adjusted in real time, and the signal transmitter 300 in the corresponding direction is used to send the second signal, thereby ensuring the signal strength, so that the rescue of the marine lifesaving system is more stable.

[0085] In summary, the present invention provides a multi-stage marine communication antenna and a communication method, wherein the multi-stage marine communication antenna comprises: an antenna body 100, a signal receiving column 200 and a plurality of signal transmitters 300; the signal receiving column 200 is arranged through the antenna body 100; a plurality of the signal transmitters 300 are arranged on the side wall of the antenna body 100 in a circular array; a controller is arranged in the antenna body 100; the signal receiving column 200 is suitable for receiving first signals in different directions and sending them to the controller; the controller is suitable for controlling the signal transmitter 300 in the corresponding direction to send a second signal according to the direction of the received first signal. The first signals in different directions are received by the signal receiving column 200, and the direction of the first signal is determined by the controller. When the antenna body 100 undergoes fluctuation rotation, the direction of sending the second signal is adjusted in real time, and the signal transmitter 300 in the corresponding direction is used to send the second signal, thereby ensuring the signal strength.
