[0002] With the continuous development of ship satellite communication technology, the corresponding equipment is also constantly updated. In order to achieve multi-band Internet access and global coverage without dead spots, the problem of antenna arrangement becomes crucial. And the problem of antenna arrangement ultimately boils down to the transmission problem of radio waves, that is, to make the distribution of electromagnetic fields and electromagnetic waves within a certain space range meet electromagnetic compatibility.

[0003] Generally, each antenna needs to be arranged in a place where it is open all around, without obstruction, far from various metal structures and other antennas. If good communication between devices is to be ensured, the mutual distance between antennas must be ensured to reduce mutual interference between antennas.

[0004] However, it is impossible to arrange antennas perfectly on the limited compass deck and radar mast according to theory. There is a lack of a quantitative standard for the coverage degree of antennas, making it difficult to adjust the equipment according to the quantitative standard.

The components of the embodiments of the present application described and illustrated in the accompanying drawings here may be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application to be protected, but only represents the selected embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative efforts fall within the protection scope of the present application.

[0069] It should be noted that the term "including" will be used in the embodiments of the present application to indicate the existence of the features stated thereafter, but does not exclude the addition of other features.

[0070] Considering the continuous development of ship satellite communication technology, the corresponding equipment is also constantly updated. In order to achieve multi-band Internet access and global coverage without dead spots, the problem of antenna layout becomes crucial. The problem of antenna layout ultimately boils down to the transmission problem of radio waves, that is, to make the distribution of electromagnetic fields and electromagnetic waves within a certain space meet electromagnetic compatibility.

[0071] Usually, each antenna needs to be arranged in a place where the surrounding is open, unobstructed, far from various metal structures and other antennas. If good communication between devices is to be ensured, the mutual distance between antennas must be ensured to reduce mutual interference between antennas. However, it is impossible to arrange antennas perfectly on the limited compass deck and radar mast according to theory. There is a lack of a quantitative standard for the coverage of antennas, making it difficult to adjust the equipment according to the quantitative standard. Moreover, there are many blind spots in antenna layout that are difficult to visualize, resulting in general signal coverage.

[0072] To solve this problem, the present application provides a method and device for calculating blind spots in antenna equipment layout. By pulling corresponding tangents to the target outfitting parts based on the position information of the antenna equipment and obtaining the working coverage area and working occlusion blind spots of the antenna equipment according to the tangents of the target outfitting parts, and further drawing the corresponding blind spot map, the blind spots in antenna equipment layout are visualized, realizing the quantification of the coverage degree of antenna equipment layout. The antenna equipment can be adjusted according to the quantified blind spot map, thereby improving the signal coverage of the antenna equipment and reducing the blind spots in antenna equipment layout.

[0073] Figure 1 is a flowchart of the method for calculating blind spots in antenna equipment layout according to an embodiment of the present application, which is applied to antenna equipment arranged on a ship (such as a bulk carrier, a large passenger ship, a car carrier, etc.), and is specifically applied to antenna equipment arranged on the compass deck and / or radar mast of a ship; as Figure 1 shown, the method for calculating blind spots in antenna equipment layout according to an embodiment of the present application may specifically include:

[0074] S101. Obtain the position information of the antenna equipment already arranged on the ship, and pull corresponding tangents to the preset target outfitting parts based on the position information to obtain the tangents of each target outfitting part.

[0075] S102. Obtain the working coverage area of the antenna equipment according to the tangents of the target outfitting parts, and determine the working occlusion blind spots of the antenna equipment according to the working coverage area.

[0076] S103. Obtain the total occlusion blind spots of all antenna equipment according to the working occlusion blind spots of all antenna equipment, and overlap the working coverage areas of all antenna equipment to obtain the overlapping coverage area of all antenna equipment.

[0077] S104. Draw a corresponding blind area map based on the total occlusion blind area, overlapping coverage area, and the working coverage area of each antenna device, and in response to the blind area map not meeting the preset blind area map standard requirements, adjust the antenna device based on the blind area map.

[0078] In the above antenna device layout blind area calculation method, by pulling out corresponding tangents to the target outfitting parts based on the position information of the antenna devices and obtaining the working coverage area and working occlusion blind area of the antenna devices according to the tangents of the target outfitting parts, and further drawing the corresponding blind area map, the blind area of the antenna device layout is visualized, realizing the quantification of the coverage degree of the antenna device layout. The antenna device can be adjusted according to the quantified blind area map, thereby improving the signal coverage of the antenna device and reducing the blind area of the antenna device layout.

[0079] The following Figures 1-4 , combined with specific examples, will illustrate the above exemplary steps of the embodiments of the present application:

[0080] S101. Obtain the position information of the antenna devices already arranged on the ship, and pull out corresponding tangents to the preset target outfitting parts based on the position information to obtain the tangents of each target outfitting part.

[0081] It should be noted that the antenna devices of the present application at least include network antennas, radars, and maritime satellites, that is, the antenna devices of the present application include all antenna devices on the ship. Among them, the network antennas include, but are not limited to, VAST, FBB, IRIDIUM, and LTE4G. The antenna devices can be arranged on the compass deck and / or radar mast of the ship. For example, the radar is arranged on the radar mast. The present application takes the network antennas VAST (VAST1, VAST2) and FBB arranged on the compass deck as examples of antenna devices for description. VAST is a commonly used network antenna, but it does not limit the antenna devices. Obviously, the present method is also applicable to the arrangement of other antenna devices (such as radars and maritime satellites) or radar masts, and can be specifically set according to the actual situation.

[0082] In the embodiments of the present application, the antenna devices are the antenna devices already arranged on the ship. Multiple antenna devices can be arranged on the ship. Specifically, as Figure 2 shown, multiple network antennas VAST are arranged on the compass deck, and the VASTs are respectively arranged on the port and starboard sides of the ship. The position information is the position information of each antenna device. The target outfitting parts are relatively large outfitting parts on the ship. The target outfitting parts at least include light masts, water cannons, chimneys, and radar masts. Each target outfitting part corresponds to a tangent one by one. For the multiple antenna devices arranged on the ship, obtain the position information of each antenna device, and pull out corresponding tangents to the target outfitting parts based on the position information of each antenna device to obtain the tangents of each target outfitting part for subsequent processing. For example, as Figure 2As shown in the figure, the two sides of the gap between the two larger fan-shaped areas at the upper part of the figure are the tangents of a target outfitting piece.

[0083] S102. Obtain the working coverage area of the antenna device according to the tangents of the target outfitting piece, and determine the working occlusion blind area of the antenna device according to the working coverage area.

[0084] In the embodiment of the present application, the working coverage area is the effective working coverage area of the antenna device, that is, the area where the signal of the antenna device can be effectively covered. The colors of the working coverage areas of different antenna devices are different; the working occlusion blind area is the occlusion blind area of the antenna device, that is, the area where the signal of the antenna device cannot be effectively covered. The working occlusion blind area is also the working occlusion blind area angle and the working occlusion blind area angle diagram. The working occlusion blind area includes multiple occlusion blind area angles, and the colors of the working occlusion blind areas of different antenna devices are different; obtain the working coverage area of the antenna device according to the tangents of the target outfitting piece obtained in step S101, and determine the working occlusion blind area of the antenna device according to the obtained working coverage area of the antenna device for subsequent processing.

[0085] For example, as Figure 2 shown, Figure 2 the multiple shaded fan-shaped areas in it are the working coverage areas of all network antennas (VAST1 and VAST2). Among them, all the light shaded fan-shaped areas are the working coverage areas of VAST1, and all the dark shaded fan-shaped areas are the working coverage areas of VAST2. It can be seen that the working coverage area of VAST1 includes multiple light shaded fan-shaped areas, corresponding to multiple coverage angles. For example, the multiple light shaded fan-shaped areas of VAST1 respectively correspond to 119.0°, 88.0°, 15.0° and 7.0°, and the same is true for VAST2; as Figure 3 shown, after obtaining the working coverage areas of the antenna devices as shown in Figure 2 i.e., the working coverage areas of VAST1 and VAST2, the working blind area of VAST1 can be determined according to the working coverage area of VAST1, and the working blind area of VAST2 can be determined according to the working coverage area of VAST2. Obviously, it can be simply understood that there is a complementary relationship between the working coverage area and the working blind area here.

[0086] It should be noted that when determining the working coverage area of the antenna device, for the working coverage area of the antenna device, the color matching the working coverage area of the antenna device can be determined, and based on the matching color, the working coverage area of the antenna device is drawn to obtain the drawn working coverage area of the antenna device. Among them, the drawn working coverage area of the antenna device is also the colored working coverage area of the antenna device. For example, according to different colors, the working coverage areas of different antenna devices are drawn. For VAST1, the working coverage area of VAST1 is drawn as yellow, and for VAST2, the working coverage area of VAST2 is drawn as pink.

[0087] It should also be noted that when determining the working occlusion blind area of the antenna device, for the working occlusion blind area of the antenna device, the color matching the working occlusion blind area of the antenna device can be determined, and based on the matching color, the working occlusion blind area of the antenna device is drawn to obtain the drawn working occlusion blind area of the antenna device. Among them, the drawn working occlusion blind area of the antenna device is also the colored working occlusion blind area of the antenna device, and the colors of the working occlusion blind areas of different types of antenna devices are different. For example, according to different colors, the working occlusion blind areas of different antenna devices are drawn. For VAST1, the working occlusion blind area of VAST1 is drawn as gray, and for VAST2, the working occlusion blind area of VAST2 is drawn as green.

[0088] S103, obtaining the total occlusion blind area of all antenna devices according to the working occlusion blind areas of all antenna devices, and overlapping the working coverage areas of all antenna devices to obtain the overlapping coverage area of all antenna devices.

[0089] It can be understood that the antenna devices can compensate for each other's working occlusion blind areas. The total occlusion blind area can be understood as the hard blind area that cannot be compensated after compensation. There may be an overlap between the working coverage areas of the antenna devices, that is, there may be duplicates between the working coverage areas. At this time, overlapping the working coverage areas of all antenna devices can obtain the actual effective total coverage area.

[0090] In the embodiments of the present application, the total occlusion blind area is the actual occlusion blind area obtained after all antenna devices compensate for each other, that is, the total occlusion blind area jointly formed by all antenna devices on the ship. The overlapping coverage area is the actual effective total coverage area obtained by overlapping the working coverage areas of all antenna devices, that is, the overlapping coverage angle of all antenna devices. For example, Figure 4As shown, the VSAT Overlap is the overlapping coverage area obtained by overlapping the working coverage areas of two network antennas, VAST1 and VAST2, which also represents the overlapping coverage area of this application. The total occlusion blind area of all antenna devices is obtained based on the working occlusion blind areas of all antenna devices obtained in step S102. The working coverage areas of all antenna devices obtained in step S102 are overlapped to obtain the overlapping coverage area of all antenna devices for subsequent processing.

[0091] S104. Draw corresponding blind area maps based on the total occlusion blind area, the overlapping coverage area, and the working coverage area of each antenna device, and in response to the blind area map not meeting the preset blind area map standard requirements, adjust the antenna devices based on the blind area map.

[0092] In the embodiments of this application, the blind area map is the blind area map summarized by all the antenna devices on the ship, that is, the actual signal coverage map summarized by all the antenna devices. The blind area map includes the working coverage area of each antenna device, the overlapping coverage area of all antenna devices, and the total occlusion blind area. For example, as Figure 4 shown, the blind area map standard requirements are the preset standard requirements for the blind area. For example, the blind area standard requirements from the shipowner, the blind area standard requirements of the antenna device itself, etc. Based on the total occlusion blind area of all antenna devices obtained in step S103, the overlapping coverage area of all antenna devices, and the working coverage area of each antenna device obtained in step S102, draw the corresponding blind area map of all the antenna devices on the ship, and determine whether the blind area map meets the preset blind area map standard requirements. If the blind area map does not meet the preset blind area map standard requirements, then adjust the corresponding antenna device based on the blind area map. Specifically, for the antenna device, determine the blind area standard requirements of the antenna device, and adjust the position of the antenna device based on the blind area standard requirements and the working occlusion blind area of all antenna devices in the blind area map.

[0093] It should be noted that for the example of the network antenna of this application, the working coverage area, the working occlusion blind area, and the blind area map are all two-dimensional plane graphs, which can be specifically understood as top views, just as Figure 2 、 Figure 3 shown and Figure 4 shown, while for the maritime satellite and radar, the working coverage area, the working occlusion blind area, and the blind area map are three-dimensional three-view drawings (including the front view, the top view, and the side view), that is, the working coverage area, the working occlusion blind area, and the blind area map of the maritime satellite and radar each have a front view, a top view, and a side Figure 3 view drawing.

[0094] The antenna device layout blind area calculation method provided by the embodiments of the present application obtains the position information of the antenna devices already arranged on the ship, and based on the position information, draws corresponding tangents to the preset target outfitting parts to obtain the tangents of each target outfitting part. The working coverage area of the antenna device is obtained according to the tangents of the target outfitting parts, and the working occlusion blind area of the antenna device is determined according to the working coverage area. The total occlusion blind area of all antenna devices is obtained according to the working occlusion blind areas of all antenna devices. The working coverage areas of all antenna devices are overlapped to obtain the overlapping coverage area of all antenna devices. A corresponding blind area map is drawn based on the total occlusion blind area, the overlapping coverage area, and the working coverage area of each antenna device. And in response to the blind area map not meeting the requirements of the preset blind area map standard, the antenna device is adjusted based on the blind area map. In the antenna device layout blind area calculation method of the present application, by drawing corresponding tangents to the target outfitting parts based on the position information of the antenna devices and obtaining the working coverage area and the working occlusion blind area of the antenna device according to the tangents of the target outfitting parts, and further drawing the corresponding blind area map, the blind area of the antenna device layout is visualized, realizing the quantification of the coverage degree of the antenna device layout. The antenna device can be adjusted according to the quantified blind area map, thereby improving the signal coverage of the antenna device and reducing the blind area of the antenna device layout.

[0095] Further, as Figure 5 shown, the step of "obtaining the position information of the actual model of the antenna devices already arranged on the ship" in step S101 in the above embodiment may specifically include the following steps:

[0096] S501, for the antenna devices already arranged on the ship, obtain the actual models of the antenna devices.

[0097] In the embodiments of the present application, the actual model is the three-dimensional model (stereoscopic model) corresponding to each antenna device. For all the antenna devices already arranged on the ship, obtain the actual model corresponding to each antenna device for subsequent processing.

[0098] S502, obtain the position information of the antenna device based on the actual model of the antenna device.

[0099] In the embodiments of the present application, according to the actual model of each antenna device obtained in step S501, the position information of the antenna device is obtained for subsequent processing.

[0100] Further, as Figure 6 shown, the step of "drawing corresponding tangents to the preset target outfitting parts based on the position information" in step S101 in the above embodiment may specifically include the following steps:

[0101] S601, for the target outfitting part, determine the outermost edge point of the target outfitting part based on the position information.

[0102] In the embodiment of the present application, the outermost edge points are the points corresponding to the outermost edge parts of the target outfitting parts, that is, the outermost edge points at both ends. For the preset target outfitting parts, based on the position information of the antenna device obtained in the above embodiment, the outermost edge points of each target outfitting part are determined for subsequent processing. For example, when the target outfitting part is a lamp mast, the corresponding points at the outermost edge parts at both ends of the lamp mast are determined as the outermost edge points.

[0103] S602. Pull a corresponding tangent line to the target outfitting part based on the edge points of the target outfitting part and the antenna device.

[0104] In the embodiment of the present application, based on the outermost edge points of the target outfitting part determined in step S601 and the antenna device, a corresponding tangent line is pulled to the target outfitting part, that is, a tangent line is pulled between each outermost edge point of the target outfitting part and the corresponding antenna device (here it is also regarded as a point, such as the point at the center position of the antenna device representing the antenna device), so that two tangent lines are pulled from the two outermost edge points of the target outfitting part to form the above-mentioned working occlusion blind area.

[0105] Further, as Figure 7 shown, the step of "obtaining the working coverage area of the antenna device according to the tangent line of the target outfitting part" in step S102 in the above embodiment specifically includes the following steps:

[0106] S701. Obtain at least one working coverage angle of the antenna device according to the tangent line of the target outfitting part.

[0107] In the embodiment of the present application, the working coverage area of the antenna device includes multiple working coverage angles, that is, the antenna device includes at least one working coverage angle, and the working coverage area is also the working coverage angle diagram. According to the tangent line of the target outfitting part obtained in the above embodiment, at least one working coverage angle of the corresponding antenna device is obtained for subsequent processing. For example, as Figure 2 shown, according to the tangent line of the target outfitting part, multiple working coverage angles of VAST1 are obtained: 119.0°, 15.0°, 7.0° and 88.0°, and multiple working coverage angles of VAST2 are obtained: 12.0°, 19.0°, 75.0°, 105.0° and 43.0°.

[0108] S702. Superimpose all the working coverage angles of the antenna device to obtain the working coverage area of the antenna device.

[0109] In the embodiment of the present application, all the working coverage angles of the antenna device obtained in step S701 are superimposed to obtain the working coverage area of the antenna device. For example, as Figure 2As shown, the multiple working coverage angles of VAST1 are: 119.0°, 15.0°, 7.0° and 88.0°. The working coverage areas of VAST1 are obtained by superimposing these working coverage angles. The same applies to VAST2.

[0110] Furthermore, as Figure 8 shown, the step of "determining the working occlusion blind area of the antenna device according to the working coverage area" in step S102 of the above embodiment may specifically include the following steps:

[0111] S801. For the working occlusion blind areas of all antenna devices, determine the first compensation blind area that needs to be compensated in the working occlusion blind area of each antenna device, the other antenna devices that compensate the first compensation blind area, and the first compensation coverage area in the working coverage area of the other antenna devices that compensates the first compensation blind area.

[0112] In the embodiment of the present application, the first compensation blind area is the part of the working occlusion blind area of each antenna device that needs to be compensated. The other antenna devices are the antenna devices other than the antenna device corresponding to the first compensation blind area that can compensate the first compensation blind area. The first compensation coverage area is the working coverage area required to compensate the first compensation blind area in the working coverage area of the other antenna devices. The first compensation coverage area corresponds to the other antenna devices. For the working occlusion blind areas of all antenna devices obtained in the above embodiment, determine the first compensation blind area that needs to be compensated in the working occlusion blind area of each antenna device, the other antenna devices that compensate the first compensation blind area, and the first compensation coverage area in the working coverage area of the other antenna devices that compensates the first compensation blind area for subsequent processing. For example, as Figure 2 and Figure 3 shown, Figure 3 the first compensation blind area of 26.0° that needs to be compensated in the working occlusion blind area of VAST1 in Figure 2 can be compensated by the first compensation coverage area of 75.0° in the working coverage area of VAST2 in

[0113] S802. Compensate the first compensation blind area based on the first compensation coverage area to obtain the actual working occlusion blind area of each compensated antenna device, and obtain the total occlusion blind area of all antenna devices based on the actual working occlusion blind area of each antenna device.

[0114] In the embodiment of the present application, the actual working occlusion blind area is the actual working occlusion blind area obtained after the working occlusion blind area of each antenna device is compensated. Compensate the first compensation blind area based on the first compensation coverage area obtained in step S801 to obtain the actual working occlusion blind area of each compensated antenna device, and obtain the total occlusion blind area of all antenna devices based on the actual working occlusion blind area of each antenna device. For example, as Figure 2 andFigure 3 As shown, the first compensation coverage area of 75.0° in the working coverage area of VAST2 compensates for the first compensation blind area of 26.0° that needs to be compensated in the working blind area of VAST1. It should be noted that the compensation of antenna devices is mutual. For example, when VAST2 compensates VAST1, VAST1 also compensates VAST2.

[0115] Furthermore, as Figure 9 shown, the step of "responding to the blind area map not meeting the preset blind area map standard requirements and adjusting the antenna device based on the blind area map" in step S104 in the above embodiment may specifically include the following steps:

[0116] S901, in response to the total occlusion blind area in the blind area map not meeting the preset blind area map standard requirements, dynamically adjust the total occlusion blind area until the adjusted total occlusion blind area meets the blind area map standard requirements.

[0117] In the embodiment of the present application, it is judged whether the total occlusion blind area in the blind area map meets the preset blind area map standard requirements. If not, the total occlusion blind area is dynamically adjusted until the adjusted total occlusion blind area meets the preset blind area map standard requirements.

[0118] S902, adjust the position of the corresponding antenna device based on the adjusted total occlusion blind area.

[0119] In the embodiment of the present application, the position of the corresponding antenna device is adjusted according to the adjusted total occlusion blind area obtained in step S901. For example, as Figure 3 shown, the working occlusion blind area of 8.0° of VAST1 is a real hard blind area and cannot be compensated. At this time, if the working occlusion blind area of 8.0° does not meet the blind area map standard requirements, for example, the shipowner does not accept the working occlusion blind area of 8.0°, then at this time, the working occlusion blind area of 8.0° can be adjusted to meet the blind area map standard requirements, and then the position of the corresponding antenna device is further adjusted.

[0120] It should be noted that when the working occlusion blind area does not meet the blind area map standard requirements, relevant outfitting parts can also be removed. For example, the lamp mast corresponding to the working occlusion blind area of 8.0° is removed and installed at other positions, which will not be elaborated here.

[0121] Furthermore, when the antenna device is a radar or a maritime satellite, the distance between the antenna devices is judged based on the actual model of the antenna device; when the distance between the antenna devices meets the requirements (for example, the distance requirement of two meters), it is determined that the corresponding antenna devices do not interfere with each other, and there is no need to calculate the working occlusion blind area of the corresponding antenna devices. If the distance between the antenna devices does not meet the requirements (for example, the distance is relatively small), then the working occlusion blind area of the corresponding antenna devices needs to be calculated.

[0122] It should be noted that the method for calculating the blind area of the antenna device layout in this application, that is, the method for calculating the blind area of the network antenna layout.
