Description

Technical Field

[0001] This application relates to the field of satellite compass technology, and in particular to an antenna bracket, a satellite compass, and communication equipment. Background Technology

[0002] A satellite compass is a device that uses satellite signals for positioning and orientation. It can acquire high-precision orientation angle data, attitude angle data, centimeter-level positioning accuracy, and elevation data, enabling precise target coordinates in scenarios such as forest fire prevention and boundary protection.

[0003] Satellite compasses can connect to various communication devices to achieve navigation and communication functions. For example, when connected to a network camera, satellite compasses data can be fused with the network camera's image data, enabling real-time analysis and early warning of the monitored scene through intelligent algorithms. Similarly, satellite compasses can connect to ship monitoring equipment, providing heading and attitude information to help identify the ship's motion status. During installation, satellite compasses require physical fixation and calibration to ensure stable positioning and avoid signal interference and errors. However, currently, satellite compasses lack a positioning structure, making it difficult to accurately locate their installation position during installation. This can easily lead to installation errors and affect the accuracy of the satellite compasses' data.

[0004] Therefore, in view of the above-mentioned technical problems, how to accurately position the satellite compass at the installation location is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0034] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0035] It should be noted that in this embodiment, the orientation or positional relationship indicated by terms such as "upper," "lower," "front," and "rear" is based on the orientation or positional relationship shown in the accompanying drawings. It is used only for the convenience of describing this application and for simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this application. Furthermore, "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0036] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] like Figure 1 and Figure 2 As shown, in this embodiment, an antenna bracket is provided. The antenna bracket 11 can be fixedly connected to the fixing frame 2, thereby fixing the satellite compass 1 as a whole on the fixing frame 2. The antenna bracket 11 includes a positioning part 112 that contacts the surface of the fixing frame 2. After the positioning part 112 contacts the surface of the fixing frame 2, the positioning part 112 can be limited to abut against the fixing frame 2 in the X direction. Since the two have a certain contact area, the abutment effect in the X direction is more stable, ensuring the positioning effect in the X direction.

[0038] It should be noted that in a three-dimensional coordinate system, the X direction usually represents the two directions of the X-axis. In this embodiment, after the positioning part 112 is limited and abutted against the fixing frame 2, it is sufficient to ensure that the positioning part 112 cannot continue to move along one direction of the X-axis relative to the fixing frame 2. Of course, after the positioning part 112 abuts against the fixing frame 2, that is, under the premise that the positioning part 112 cannot move along one direction of the X-axis, a constraint mechanism can be set on the fixing frame 2 to constrain the positioning part 112 from moving along the other direction of the X-axis, thereby realizing the limiting and locking of the positioning part 112 relative to the fixing frame 2 in the two directions of the X-axis, ensuring the accurate positioning of the antenna bracket 11 in the X-axis.

[0039] Furthermore, the constraint mechanism can be an L-shaped limiting member. The horizontal side of the L-shaped limiting member is rotatably connected to the fixed frame 2, and the vertical side of the L-shaped limiting member forms a space between the fixed frame 2 to accommodate the positioning part 112. When the first surface of the positioning part 112 contacts the surface of the fixed frame 2, the vertical side of the L-shaped limiting member can be rotated to abut against the second surface of the positioning part 112, thereby stably clamping the positioning part 112 on the fixed frame 2 and ensuring the positioning accuracy in the X direction.

[0040] Of course, in order to simplify the installation steps of the antenna bracket 11, it is only necessary to limit the positioning part 112 to abut against the fixing frame 2. The above-mentioned constraint mechanism can be replaced by external force pressing, so that the positioning part 112 can stably abut against the fixing frame 2 in the X direction.

[0041] In some embodiments, the positioning part 112 includes a positioning plane or a positioning arc surface that contacts the fixing frame 2. The corresponding contact surface between the fixing frame 2 and the positioning part 112 should also be a plane or an arc surface, so that the positioning part 112 can contact the fixing frame 2. The positioning plane only has the effect of limiting and abutting in the X direction, but does not have a certain limiting effect in the Y or Z direction. Preferably, a positioning arc surface can be provided on the positioning part 112. After the positioning arc surface contacts the arc surface of the fixing frame 2, it can exert a certain constraint effect on the positioning part 112 in the Y or Z direction under the action of the arc contact surface, so that the positioning part 112 can be quickly set in the position to be installed.

[0042] Furthermore, the positioning arc surface of the positioning part 112 can be a conical surface, which can be a conical surface or an arc-shaped pyramidal surface. A conical groove is provided on the corresponding fixing frame 2. The cooperation between the conical surface and the conical groove can simultaneously play a constraining role in the Y and Z directions, so that the positioning part 112 can be accurately set at the installation position.

[0043] The surface contact between the positioning part 112 and the fixing part 2, as described above, can provide some constraint on the positioning part 112 in the Y and Z directions, but it still cannot ensure the movement of the positioning part 112 in the Y and Z directions. For example, during the fixing process between the positioning part 112 and the fixing part, the positioning part 112 may shift due to assembly errors, operational errors, etc. Therefore, in this embodiment, the positioning part 112 is also provided with a limiting part 114 and a fixing part 115. Please refer to... Figure 2 The limiting part 114 can be inserted into the fixing frame 2, thereby limiting the limiting part 114 and the fixing frame 2 in the Y and Z directions. That is, during the process of the positioning part 112 abutting against the fixing frame 2 in the X direction, the limiting part 114 can gradually insert into the fixing frame 2, and after the positioning part 112 abuts against the fixing frame 2 in the X direction, the limiting part 114 and the fixing frame 2 are completely inserted. At this time, the limiting part 114 and the fixing frame 2 achieve limiting and locking in the Y and Z directions. After the positioning part 112 achieves three-way positioning relative to the fixing frame 2 in the X, Y, and Z directions, it can be fixedly connected to the fixing frame 2 through the fixing part 115 on the positioning part 112. The fixing part 115 can be a screw hole, and a corresponding screw hole is also provided on the fixing frame 2. The positioning part 112 is fixed to the fixing frame 2 by screws, thereby achieving precise positioning and precise installation of the antenna bracket 11 relative to the fixing frame 2. In summary, this application achieves the positioning of the antenna support 11 relative to the fixed frame 2 in the X direction by having the positioning part 112 on the antenna support 11 abut against the fixed frame 2. The positioning of the antenna support 11 relative to the fixed frame 2 in the Y and Z directions is achieved by the limiting part 114 on the positioning part 112 engaging with the fixed frame 2 in the Y and Z directions. Through positioning in the X, Y, and Z directions, the antenna support 11 can be accurately positioned on the fixed frame 2, ensuring the positioning accuracy of the satellite compass 1 during installation. After positioning is completed, the fixing part 115 on the positioning part 112 achieves a fixed connection with the fixed frame 2, ensuring the installation accuracy of the satellite compass 1.

[0044] Antenna bracket 11 also includes mounting surface 111 for mounting antenna 12, please refer to Figure 1 The mounting surface 111 can be a planar structure, and the antenna 12 is mounted at both ends of the mounting surface 111 along its length. In some embodiments, the mounting surface 111 can be a rectangular surface, and the positioning part 112 is located at the first long side of the mounting surface 111. The contact surface between the positioning part 112 and the fixing frame 2 and the mounting surface 111 are located in different planes, thereby avoiding the situation where the mounting surface 111 and the fixing frame 2 come into contact, which would prevent the antenna 12 from being installed on the mounting surface 111 or affect the installation position of the antenna 12.

[0045] Specifically, the positioning part 112 can be set perpendicular to the mounting surface 111. For example, if the mounting surface 111 is a horizontal plane, the corresponding positioning part 112 is set vertically, and the contact surface between the positioning part 112 and the fixing frame 2 is a vertical plane.

[0046] Both the limiting part 114 and the fixing frame 2 include a limiting hole, and the other part is provided with a limiting pin that is inserted into the limiting hole; that is, when the limiting part 114 is a limiting hole, a corresponding limiting pin is provided on the fixing frame 2; when the fixing frame 2 is provided with a limiting hole, the limiting part 114 is the corresponding limiting pin. The limiting pin can be inserted into the limiting hole along the X direction, and the hole wall of the limiting hole fits against the outer peripheral surface of the limiting pin, thereby limiting the limiting pin by the limiting hole, realizing the limiting engagement of the two in the Y and Z directions.

[0047] Furthermore, the limiting part 114 can be provided in a manner including, but not limited to, the limiting hole or limiting pin mentioned above, or it can be a limiting groove or a limiting block, etc., to ensure that the limiting part 114 can be locked in place with the fixing frame 2 in the Y and Z directions.

[0048] Based on the above embodiments, the limiting pin and the limiting hole can also be engaged circumferentially to restrict the rotation of the limiting pin relative to the limiting hole, and to limit the relative angle when the limiting pin and the limiting hole are inserted. For example, if the limiting pin is a column with a D-shaped cross-section, the corresponding limiting hole is also a D-shaped hole. After the limiting hole and the limiting pin are inserted, they cannot rotate. Furthermore, the shape of the limiting hole can only be inserted if it corresponds to the shape of the limiting pin. Similarly, if the limiting pin is a cuboid column, and the corresponding limiting hole is a rectangular hole, it can also restrict the rotation of both and limit the relative angle when they are inserted.

[0049] In addition, the limiting pin can also be set as a column with an irregular cross-section, and the shape of the corresponding limiting hole corresponds to the limiting pin, so as to ensure that the limiting pin can be inserted into the limiting hole. These will not be described in detail here, but all of them fall within the protection scope of this application.

[0050] Since the antenna bracket 11 has a certain length, in order to ensure the supporting effect of the fixing frame 2 on the antenna bracket 11, the positioning part 112 can be set to at least two, please refer to Figure 1 and Figure 2 Multiple positioning parts 112 are evenly distributed on the first long side of the mounting surface 111, so that the supporting force of the fixing seat is more evenly applied to the antenna bracket 11.

[0051] Each positioning part 112 can be connected to the corresponding mounting frame 2. At the same time, the contact surfaces of each positioning part 112 and the mounting frame 2 are located in the same plane, so that each positioning part 112 can achieve the positioning effect in the X, Y and Z directions. In addition, the arrangement of multiple positioning parts 112 can also achieve the purpose of multi-point fixation, making the mounting surface 111 and the antenna 12 on the mounting surface 111 more stable, and ensuring the data accuracy of the satellite compass 1.

[0052] This application also provides a satellite compass 1, please refer to... Figure 1 The satellite compass 1 includes an antenna bracket 11, an antenna 12, and a GNSS module 19. The antenna bracket 11 is the same as described above, and the antenna 12 is fixedly mounted at both ends of the mounting surface 111 of the antenna bracket 11. The GNSS module 19 is sealed and mounted on the antenna bracket 11, and the GNSS module 19 and the antenna 12 are connected via a coaxial cable 18 to enable communication between them. The satellite compass 1 can be precisely positioned at the required location using the antenna bracket 11, thereby improving the installation accuracy and data accuracy of the satellite compass 1.

[0053] The GNSS module 19 is located in the center of the antenna bracket 11. The GNSS module 19 is equidistant from the antennas 12 at both ends. This equidistant layout can reduce the difference in signal transmission delay, ensure that the phase difference calculation of satellite signals received by multiple antennas 12 is more accurate, and reduce the accumulation of multipath reflection errors caused by distance differences, which affects positioning accuracy and ensures the overall positioning reliability of the satellite compass 1.

[0054] The satellite compass 1 also includes a sealing assembly fixedly disposed on the side of the antenna bracket 11 opposite to the mounting surface 111. The mounting surface 111 is typically the upper surface of the antenna bracket 11. The antenna 12 is mounted on the upper side of the antenna bracket 11, while the sealing assembly is mounted on the lower side of the antenna bracket 11. The GNSS module 19 is disposed within the sealing assembly, thereby achieving waterproofing of the GNSS module 19. Specifically, the sealing assembly includes a housing 15, a sealing gasket 14, and a cover plate 13. The GNSS module 19 is fixedly disposed within the housing 15, and an opening is provided on one side of the housing 15, through which the GNSS module 19 can be installed or removed.

[0055] Please refer to Figure 1 A circumferentially distributed step is provided on the inner wall of the opening side of the housing 15. The sealing gasket 14 can be provided at the step 151. The sealing gasket 14 is pressed onto the step 151 by the cover plate 13, thereby achieving a sealed connection between the cover plate 13 and the housing 15, ensuring the sealed setting of the GNSS module 19 inside the housing 15. That is, the cover plate 13 is fixed to the opening side of the housing 15 and has an interference fit with the sealing gasket 14. Similarly, under the compression of the cover plate 13, the sealing gasket 14 can also have an interference fit with the step 151, realizing the sealing setting of the sealing assembly.

[0056] The sealing assembly is also fixedly connected to the antenna bracket 11. Specifically, the cover plate 13 or the housing 15 is fixedly connected to the antenna bracket 11 to ensure that the GNSS can be set up stably.

[0057] Please refer to Figure 1The housing 15 also has a connection hole 152 for the coaxial cable 18 to pass through, and a communication hole 153 for the communication connector 16 to pass through. Since there are two antennas 12, there are also two corresponding coaxial cables 18. One end of the coaxial cable 18 is connected to the antenna 12, and the other end is inserted into the plug-in terminal of the GNSS module 19. Therefore, there are also two connection holes 152, which are respectively arranged on the left and right sides of the housing 15. The coaxial cable 18 and the connection hole 152 can be sealed with sealant or with a rubber sealing plug. The rubber sealing plug is placed at the connection hole 152, and the coaxial cable 18 can pass through the rubber sealing plug. The rubber sealing plug is press-fitted with both the coaxial cable 18 and the connection hole 152, thereby achieving a seal between the connection hole 152 and the coaxial cable 18. In addition, there are other forms of sealing between the cable and the hole, which will not be described in detail here, but all fall within the scope of protection of this application.

[0058] Similarly, the communication connector 16 is also sealed to the communication port 153. The sealing method can be the same as described above, and will not be repeated here. The communication connector 16 can be a waterproof aviation cable connector. One end of the communication connector 16 is connected to the signal of the GNSS module 19, and the other end is connected to the device body 3 of the communication equipment, so as to realize the communication between the GNSS module 19 and the device body 3.

[0059] The satellite compass 1 also includes a wire guard 17, please refer to... Figure 1 The cable guard 17 is located on the side of the antenna bracket 11 away from the mounting surface 111. One end of the cable guard 17 abuts against the housing 15 on the outer periphery of the connection hole, and the other end extends toward the side where the antenna 12 is located. The coaxial connecting line 18 is located between the cable guard 17 and the antenna bracket 11, thereby protecting the coaxial connecting line 18.

[0060] Please refer to Figures 1 to 3 The outer edge of the mounting surface 111 is provided with a protective plate 113 extending toward the cable guard 17. The protective plate 113, the cable guard 17, and the antenna bracket 11 enclose a receiving space for accommodating the coaxial connecting line 18. Foam for positioning the coaxial connecting line 18 is filled in the receiving space to ensure the stability of the coaxial connecting line 18. A wire hole is provided on the antenna bracket 11 for the coaxial connecting line 18 to pass through, ensuring that the coaxial connecting line 18 can be stably connected to the antenna 12.

[0061] In addition, a fixing piece 171 overlapping with the protective plate 113 is provided on the wire protection cover 17, so that the wire protection cover 17 and the protective plate 113 can be fixed at the overlapping point by screws. The wire protection cover 17 can also be directly connected to the antenna bracket 11 by screws to ensure the connection stability between the wire protection cover 17 and the antenna bracket 11.

[0062] Furthermore, the GNSS module 19 of satellite compass 1 includes a positioning unit and a control unit. The positioning process of satellite compass 1 in this embodiment is as follows:

[0063] When satellite compass 1 receives a positioning command generated by the user, host device, or preset task triggering conditions (such as timers, displacement sensor signals, camera target recognition results, etc.), the control unit immediately activates the positioning unit, enabling it to begin receiving satellite signals. Based on the received satellite data, it performs calculations to obtain an initial positioning dataset consisting of the current location's latitude and longitude coordinates, altitude, satellite signal strength, positioning timestamp, number of visible satellites, and their distribution. This initial positioning dataset serves as the input basis for subsequent differential positioning corrections and reflects the signal conditions and positioning quality level under the current environment. Its acquisition process is affected by factors such as antenna 12 layout, environmental obstruction, and multipath interference; therefore, this initial positioning dataset has a relatively low positioning accuracy compared to the final positioning result.

[0064] The initial positioning dataset may include, but is not limited to, a combination of one or more of the following: latitude and longitude, heading angle, roll angle, and altitude, to comprehensively reflect the position and attitude of the target device in three-dimensional space. Latitude and longitude represent geographical location, heading angle reflects heading information, roll angle reflects attitude parameters, and altitude indicates vertical position.

[0065] After acquiring the initial positioning dataset (containing multi-dimensional basic positioning information such as latitude, longitude, direction, roll angle, and altitude) from the positioning unit, the control unit, acting as the core hub for data interaction, packages and uploads the initial positioning dataset to the cloud server via a pre-defined communication link (such as 4G, 5G, or satellite communication wireless transmission channels) according to a specific data format and protocol. The cloud server, acting as a remote data processing center, uses the received initial positioning dataset, combined with its own stored regional reference station observation data, to model and analyze satellite signal errors present in the initial positioning data using a differential positioning algorithm. Through error compensation and parameter optimization calculations, it generates high-precision differential positioning data.

[0066] During this process, the control unit realizes information interaction between the local positioning unit and the cloud server through the data upload mechanism. The cloud server then uses its professional data processing capabilities to perform error calibration on the initial positioning data, providing a high-precision correction basis for the subsequent positioning unit to calculate the final positioning result using differential positioning data.

[0067] After receiving differential positioning data from the cloud server, the control unit, as the core control unit for data flow, transmits the differential positioning data to the positioning unit via a pre-defined communication link (such as a wireless transmission channel or wired interface) and interaction protocol. The positioning unit, as the executing entity for positioning calculations, uses the received differential positioning data and its stored positioning algorithm model to calibrate systematic errors generated during satellite signal transmission by incorporating error correction parameters from the differential positioning data into the original positioning solution process. This eliminates or reduces the impact of environmental interference and signal quality on positioning accuracy.

[0068] In this process, the control unit achieves a closed-loop information exchange between the cloud server's processing results and the local positioning unit through a data distribution mechanism. The positioning unit then uses differential positioning data to perform in-depth optimization of the initial positioning information, ultimately generating a final positioning result that meets the requirements of high-precision application scenarios (such as centimeter-level positioning coordinates and high-reliability attitude parameters). This demonstrates the synergistic integration of cloud data processing results and local positioning calculations, and its role in improving positioning accuracy. It is important to understand that this final positioning result is the position of Satellite Compass 1 (i.e., the position of the entire unit).

[0069] This application also provides a communication device, which includes a device body 3 and a satellite compass 1. The device body 3 can be a communication device with positioning requirements, such as a PTZ network camera, which can provide high-precision orientation information to the device body 3, ensuring that the device body 3 can accurately point to the target area. The satellite compass 1 is the aforementioned satellite compass 1. A mounting bracket 2 is provided on the device body 3, and the satellite compass 1 is fixedly installed through the mounting bracket 2. The communication connector 16 on the satellite compass 1 is connected to the device body 3 for signal connection, thereby enabling communication between the GNSS module 19 and the device body 3.

[0070] Taking a PTZ network camera as an example, device 3, after acquiring the direction angle, attitude angle, and other data output by satellite compass 1, converts these angle parameters into control commands based on the camera's rotation characteristics. This drives the PTZ to adjust the camera's direction, ensuring the camera accurately points at the target area, achieving active pointing based on high-precision positioning data. The latitude, longitude, and elevation coordinate data provided by satellite compass 1 are matched with the image captured by the PTZ camera using a preset algorithm. When targets such as fire points are identified in the image, their high-precision geographic coordinates are directly marked on the image, allowing the monitoring screen to display both the on-site image and the precise location of the target, achieving accurate location of the fire point.

[0071] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0072] This document uses specific examples to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make several improvements and modifications to this application without departing from the principles of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
