Ocean network system

Abstract

The invention relates to an ocean network system. The ocean network system comprises a ship-borne signal system, a signal floating island and a remote control terminal, wherein the ship-borne signal system comprises a base, a ship-borne GPS positioning device, a ship-borne signal aligning device, and a signal-borne signal sending and receiving device; and the signal floating island comprises an island base, a solar power supply system, a signal frame, an island base GPS positioning device, a request signal receiving device, an island base signal aligning device, an island base signal sending and receiving device and a power device. The island base signal aligning device of the ocean network system receives the request signal and then authenticates the request signal; the request signal receiving device calculates according to the request signal to obtain the orientation of the ship-borne signal sending and receiving device; the regulating island base signal aligning device enables theisland base signal sending and receiving device to align to the ship-borne signal sending and receiving device, and sends out a down link signal to the ship-borne signal sending and receiving device;and after receiving the down link signal, the ship-borne signal sending and receiving device sends an up link signal to the island base signal sending and receiving device, so that high-quality network signal connection can be realized after abutting is successful.

Description

Technical field [0001] The invention belongs to the field of ocean networks, and specifically relates to an ocean-going network system. Background technique [0002] Marine satellite antennas have become more popular. The disadvantage is that they cannot receive satellite TV signals when they are far away from the shore. You can access the Internet through satellite signals. However, the Internet speed is extremely slow and the charges are expensive. In addition, it is difficult for crew members who travel at sea for a long time to communicate with land. contact, [0003] At present, the ship-to-shore wireless network shore station can already realize the wireless network connection with offshore ships, but the problems are that the network signal receiving distance is short, the upper limit of the network speed is low, the network signal is poor when the distance is slightly longer, and the security is low.

Problems solved by technology

[0002] Satellite antennas for ships are relatively popular. The disadvantage is that they cannot receive satellite TV signals when they are far away from the shore. They can access the Internet through satellite signals, but the network speed is extremely slow and the charges are expensive. In addition, it is difficult for seafarers who have traveled at sea for a long time to communicate with land normally. connect,

[0003] At present, the ship-to-shore wireless network shore station can already realize the wireless network connection with offshore ships, but there are problems such as short receiving distance of network signal, low upper limit of network speed, poor network signal when the distance is slightly farther, and low security.

But because of its fatal shortcoming - unable to pass through walls, its research lags far behind the current popular WIFI wireless transmission technology

[0006] However, on the vast ocean, except for the limited field of view caused by the curvature of the earth, there are almost no objects that can affect the propagation of light. Therefore, the value of visible light network technology in ocean networks is worth studying, and now with the People in the ocean have an increasing demand for traffic, and LIFI may become our better choice in the future
