Connected. 12 200915782 Please refer to FIG. 6 , which is a flow chart showing the steps of an embodiment of the maritime network communication method of the present invention. In the figure, the method corresponds to the maritime network system of FIG. 3, and includes the following steps: Step 61: Set a first wireless network base station 311, a first positioning system 371, and a first identification system 361. The first sea uploader 321 and a second wireless network base station 312, a second positioning system 372, and a second identification system 362 are disposed on a second sea carrier 322; Step 62: According to the WiFi communication protocol 331, The first wireless network base station 311 and the second wireless network base station 312 are respectively configured to perform wireless data transmission, and the first wireless network base station 311 and the third wireless network base station 313 installed on the land perform wireless data.

Since the seaborne carriers are far away from each other, the antenna combination structure must have the characteristics of transmitting long-distance wireless signals. In addition, the Shanghai uploading device is different from the land-based base station, and the seaborne carrier will drift with the current, and is intended to be fixed at The same location is very difficult, so the antenna combination structure must have a larger angle of detection range to ensure that the wireless signals of other base stations can still be received after the seaborne carrier moves. Please refer to FIG. 7A and FIG. 7B for a schematic diagram of the intent and signal coverage of the antenna assembly structure of the wireless network base station of the present invention applied to the sea. The antenna assembly structure disclosed in the present invention comprises a plurality of directional antennas. In the figure, the antenna assembly structure 7 comprises a plurality of directional antennas 711, 712, 713 and 714 and at least one omnidirectional antenna. Each directional antenna configuration is directed in a different direction such that the detection area of such directional antennas can encompass a range of approximately 360 degrees around the helmet network base station. In one embodiment, a directional antenna having a gain beam intensity (HPBW) of 9 degrees in a vertical direction and a horizontal direction and a gain of 23 dB or more is taken as an example. The distance at which the signal can be transmitted is 40 km. Range 72 is smaller but farther away. The gain of the area other than 9 degrees is much lower, so the signal range 73 is larger in angle but shorter in distance. The directional antennas 711, 712, 713 and 714 are respectively arranged at a predetermined angle, for example, 90 degrees. Therefore, the signal of the antenna assembly structure 7 covers the range closeness as shown in Fig. 7B. Even if the seaborne vehicle moves due to the current, the antenna assembly structure 7 has a range of nearly 360-degree signal coverage, and can be transmitted in multiple directions in the long-term 200915782. Therefore, multiple sea-loading devices can still perform sea-loading with each other- Vessels, sea-level flats or one-piece offshore structures. The above description shows the application of the present invention to a schematic diagram of the antenna assembly structure. In the figure, the structure 8 includes an omnidirectional antenna 81 and a first directivity antenna: the detection distance of the second=line 8 2 is greater than the omnidirectional antenna - the pointing direction of the one-way directional antenna 82 corresponds to ,., 'Hair uploads the second wireless network base station 84 of the eight 83 to receive the wireless signal. The omnidirectional antenna has a beam visibility of 360 degrees, so the signal detection range 811 = around the wireless network base station on the earth, can receive the adjacent signal. The signal detection mode 821 of the first-directivity antenna 82 can cover the seaborne carrier 83 which is far away. In addition, the antenna assembly structure 8 can increase at least the second directional antenna according to the distance of the sea to be transmitted by the signal, and the detection distance of the second directional antenna is greater than the detection of the first directional antenna. The distance, for example, a directional antenna with a smaller half-power beam width and a greater gain intensity. If the direction of the second directional antenna is corresponding to the second wireless network, the wireless is received from the first wireless network base station. Signal. Steps, for example, if applied to WiFi communication, the bandwidth range applicable to the omnidirectional antenna may include 5175 MHz to 5875 MHz, and the bandwidth range applicable to the first directional antenna may include 5175 MHz to 5875 MHz as needed. In addition, if the wireless network base station on the land is responsible for a wide sea surface, the antenna assembly structure 8 may further include an adjustment mechanism for rotating the directional antenna to change the direction of the directional antenna to receive all the seas on the sea.
