Problems solved by technology

[0003] However, if the ship-borne equipment on yachts, coastal patrol boats, etc. communicate with the base station tower on land, there are certain problems. The problem is that the ship-borne equipment may be relatively far away from the base station (maybe tens of kilometers) ), and if the ship moves fast, turns quickly, etc., it will also greatly affect the robustness of wireless communication

Embodiment 1

[0026] This embodiment is used to provide a shipborne device that communicates with a terrestrial base station. The shipborne device is set on a near-shore vessel. It just refers to vessels that are closer to the coast, such as yachts. The shipborne equipment communicates wirelessly with the land base station located on the coast through the main directional antenna array set on the shipborne equipment. NR (5G New Radio, 5G New Radio Access Technology) base station. The cellular base station and CPE can support wireless communication standards such as LTE and NR.

[0027] The CPE device in this embodiment wirelessly communicates with the land base station located on the coast through the main directional antenna array, that is, the CPE device adopts a directional antenna. High antenna gain to deal with long-distance signal transmission at sea, so as to solve the problem that near-shore ships are relatively far away from the coast. However, using a directional antenna is als...

Embodiment 2

[0035] This embodiment is used to provide a method for controlling a shipborne device that communicates with a terrestrial base station. figure 1 The normal direction of the shown main directional antenna array 1 is controlled as figure 2 As shown, the control method includes:

[0036] S1: Obtain the first coordinates of the land base station currently accessed by the shipborne device and the second coordinates of the near-shore vessel where it is located, and determine the land base station and the land base station according to the first coordinates and the second coordinates The connection direction of the near-shore vessel, and the normal direction of the main directional antenna array is initially adjusted based on the connection direction;

[0037] Specifically, as image 3 As shown, S1 can include:

[0038] (1) The CPE obtains the first coordinate A of the currently accessed terrestrial base station.

[0039] The CPE can obtain the GPS coordinates of the land base ...

example 1

[0058] The first auxiliary directional antenna array 2 and the second auxiliary directional antenna array 3 do not perform services, but can measure the SNR of the signal. It is assumed that only the SNR of the signal received by the first auxiliary directional antenna array 2 exceeds the preset threshold T SNR , then the normal direction of the main directional antenna array 1 is finely adjusted counterclockwise; it is assumed that only the SNR of the signal received by the second auxiliary directional antenna array 3 exceeds the preset threshold T SNR , then the normal direction of the main directional antenna array 1 is finely adjusted clockwise; it is assumed that the SNRs of the signals received by the first auxiliary directional antenna array 2 and the second auxiliary directional antenna array 3 both exceed or do not exceed the preset threshold T SNR , then the normal direction of the main directional antenna array 1 is not finely adjusted. set T here SNR =5dB, but it ...

Abstract

The invention relates to a ship-borne device that communicates with a land base station and a control method thereof. The ship-borne device communicates wirelessly with a land base station located on the coast through a main directional antenna array, and the ship-borne device is also provided with a first auxiliary directional antenna. array and a second secondary directional antenna array. The onboard equipment initially adjusts the normal direction of the main directional antenna array according to the first coordinates of the land base station and the second coordinates of the near-shore vessel, and according to the first signal quality and the second auxiliary orientation measured by the first auxiliary directional antenna array The second signal quality measured by the antenna array adjusts the normal direction of the main directional antenna array again, so that the main directional antenna array is aligned with the land base station, and then controls the normal direction of the main directional antenna array, so that the The direction of the antenna beam is always aimed at the land base station to ensure the stability of wireless communication.

Description

technical field [0001] The present invention relates to the technical field of shipborne equipment communication, in particular to a shipborne equipment that communicates with a land base station and a control method thereof. Background technique [0002] At present, some shipborne devices communicate wirelessly through satellites, but satellite communication often has problems such as low throughput and high price, which will greatly affect the wireless communication efficiency and experience of shipborne devices. In fact, some ships, including yachts, coastal patrol boats, etc., are not very far from the coast. If the base station towers of the cellular network have been arranged on the land near the coast, then the yachts, coastal patrol boats, etc. The onboard equipment above can still communicate with base station towers on land. Compared with satellites, the base station towers of cellular networks have lower network deployment costs on land and can provide greater th...
