Description

Technical Field

[0001] The present application relates to the field of satellite communication technology, and in particular to a satellite communication portable station and a satellite communication system. Background Art

[0002] At present, high-bandwidth satellite communication portable stations are mainly in the form of reflector-offset feed. Generally, the feed source is directly fixed on the feed source rod. Since the feed source of the reflector-offset feed antenna is far away from the antenna surface, it is directly attached to the antenna surface when stored. The feed source extends out of the envelope of the whole machine, taking up more space. Some manufacturers also use a detachable feed source rod to achieve the minimum envelope for storage and carrying. However, with repeated use, the position and angle of the feed source will change, which requires professionals to make fine adjustments, which brings more inconvenience and requires users and manufacturers to invest more manpower in later maintenance. Summary of the invention

[0003] The purpose of the embodiments of the present application is to provide a portable satellite communication station, which can reduce the storage and carrying envelope space of the portable satellite communication station, achieve precise adjustment of the angle of the feed position, and avoid subsequent maintenance.

[0004] The present application provides a satellite communication portable station, which includes:

[0005] Reflector antenna;

[0006] A feed support frame, comprising a pivot end and a mounting end; the reflector antenna is pivotally connected to the pivot end of the feed support frame; the reflector antenna can be folded with the feed support frame and unfolded at a predetermined angle relative to the feed support frame; the mounting end of the feed support frame is configured with a reserved space;

[0007] A feed assembly, comprising a feed, a power amplifier connected to the feed, and a rotating shaft arranged at the connection between the feed and the power amplifier, the rotating shaft being connected to the mounting end of the feed support frame, the feed and the power amplifier being configured to rotate with the rotating shaft;

[0008] A locking piece is connected to the rotating shaft configuration and is used to keep the feed assembly in a first position and a second position respectively; in the first position, the feed is facing the reflector antenna and can work normally with the reflector antenna; in the second position, the power amplifier or the power amplifier and the feed are accommodated in the reserved space at the mounting end.

[0009] In the above implementation process, the feed assembly is rotated and set at the end of the feed support frame instead of being detachable. Since the feed is always limited to the end of the feed support frame, its position will not change, and there will be no change in the installation position. The locking member fixes the feed assembly in the first position, that is, the angle of the feed toward the reflector antenna is always in the same position when the feed is working. Since the position and angle of the feed can always be located at the specified position, the satellite communication portable station in this application can achieve accurate adjustment of the position and angle of the feed, avoiding later maintenance. At the same time, the feed support frame in this application is configured with a reserved space that can accommodate a power amplifier or a power amplifier and a feed. Since the volume of the feed is usually small, when the reflector antenna and the feed support frame are in a folded state, the power amplifier and the feed can be almost considered to be completely accommodated in the reserved space of the feed support frame, so that the volume of the satellite communication portable station is only the volume of the reflector antenna and the feed support frame, thereby achieving the minimum envelope for collection and carrying, and it is more convenient to carry.

[0010] In a possible implementation, the feed support frame includes a first feed support arm and a second feed support arm which are arranged in parallel and have a predetermined distance;

[0011] The ends of the first feed support arm and the second feed support arm located at the pivot end are connected by a pivot; the reflector antenna is rotatably connected to the pivot;

[0012] The end of the first feed arm located at the mounting end is adjacent to the end of the second feed arm located at the mounting end at a predetermined distance, and the gap between the first feed arm and the second feed arm close to the mounting end constitutes a reserved space of the mounting end.

[0013] In a possible implementation, the rotating shaft includes a first rotating shaft;

[0014] A first rotating shaft passes through the connection between the feed source and the power amplifier, and one end of the first rotating shaft passes through the outer side surface of the first feed source support arm by a predetermined length;

[0015] The other end of the first rotating shaft passes through the outer side surface of the second feed source support arm for a predetermined length.

[0016] In another possible implementation, the rotating shaft includes a second rotating shaft and a third rotating shaft;

[0017] The second rotating shaft and the third rotating shaft are respectively arranged on both sides of the connection between the feed source and the power amplifier and are fixedly connected to the connection between the feed source and the power amplifier; the axis of the second rotating shaft and the third rotating shaft coincide with each other;

[0018] One end of the second rotating shaft passes through the outer side surface of the first feed source support arm by a predetermined length;

[0019] One end of the third rotating shaft passes through the outer side surface of the second feed source support arm for a predetermined length.

[0020] In a possible implementation manner, the rotating shaft is provided with an external thread;

[0021] The locking member is a threaded locking member, which is screwed into the shaft from both ends and allows the feed assembly to stay in the first position or the second position by shortening the distance between the first feed arm and the second feed arm.

[0022] In a possible implementation manner, a mechanical stopper is provided on the rotating shaft;

[0023] The first feed support arm and / or the second feed support arm are provided with a limiting groove for cooperating with the mechanical limiting member to limit the feed assembly to the second position.

[0024] In the above implementation process, the design of the mechanical limiter and the limiter slot is used to determine whether the portable satellite communication station has reached the position of the storage state. When the portable satellite communication station needs to be stored, the feed source and the power amplifier rotate together toward the direction of the reflector antenna, and the reflector antenna rotates and buckles toward the feed source. When the mechanical limiter of the rotating shaft reaches the limiter slot of the feed source support arm, the rotating shaft can no longer rotate. At this time, the threaded locking member is screwed in and locked to realize the storage of the portable satellite communication station.

[0025] In a possible implementation, a first through hole is provided on the rotating shaft, the first through hole extends along the axis direction of the rotating shaft and is a predetermined distance away from the axis of the rotating shaft;

[0026] A second through hole is provided on the first feed support arm and the second feed support arm, and when the feed assembly stays at the first position, the first through hole is communicated with the second through hole;

[0027] First photoelectric sensors are arranged on both sides of the second through hole.

[0028] In the above implementation process, the rotation angle of the rotating shaft, that is, the rotation angle of the feed assembly, is achieved by respectively opening the second through holes on the first feed arm and the second feed arm at positions corresponding to the first position where the feed assembly needs to stay, and opening the first through hole on the rotating shaft. When the first through hole is connected to the second through hole, the emission light of the first photoelectric sensor on the first feed arm passes through the first through hole to reach the receiver of the first photoelectric sensor on the second feed arm, that is, the feed assembly rotates to the first position. At this time, the rotation of the feed assembly is stopped, and the first feed arm and the second feed arm are brought closer to each other through the threaded locking member to fix the feed assembly. After the feed assembly is fixed, subsequent star search procedures and other operations can be performed.

[0029] In another possible implementation, a third through hole is provided at the end of the rotating shaft extending from the first feed support arm, and the third through hole is perpendicular to the axial direction of the rotating shaft;

[0030] A second photoelectric sensor matched with the third through hole is arranged on the outer side surface of the first feed source support arm.

[0031] Furthermore, a fourth through hole is provided at the end of the rotating shaft extending from the second feed source support arm, and the fourth through hole is perpendicular to the axial direction of the rotating shaft;

[0032] A third photoelectric sensor matched with the fourth through hole is arranged on the outer side surface of the second feed support arm.

[0033] In a second aspect, an embodiment of the present application further provides a satellite communication system, comprising the satellite communication portable station, modem and controller as described above;

[0034] The modem is connected to the power amplifier in the satellite communication portable station via a radio frequency cable; and the controller is communicatively connected to the communication portable station.

[0035] It can be seen from the above technical solution that the present application adds a rotating shaft structure at the place where the feed source and the power amplifier are connected, and the rotating shaft is used to realize the overall rotation of the feed assembly including the feed source and the power amplifier. The feed assembly is rotatably set at the end of the feed support frame, rather than being detachable. Since the feed source is always limited to the end of the feed support frame, its position will not change, and there will be no change in the installation position. At the same time, the feed support frame in the present application is configured with a reserved space that can accommodate the power amplifier or the power amplifier and the feed source, so that the volume of the satellite communication portable station is only the volume of the reflector antenna and the feed support frame, thereby achieving the minimum envelope for collection and carrying, and more convenient to carry.

DETAILED DESCRIPTION

[0042] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0043] 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 for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0044] Figure 1 This is a schematic diagram of the structure of a satellite communication portable station shown in an embodiment of the present application. Figure 1 The satellite communication portable station includes a reflector antenna 100, a feed support frame 200, a locking member 300 and a feed assembly 400.

[0045] The reflector antenna 100 is used to receive and feed back signals. The feed support frame 200 includes a pivot end 210 and a mounting end 220. The reflector antenna 100 is pivoted to the pivot end 210 of the feed support frame 200. The reflector antenna 100 can be folded with the feed support frame 200 and unfolded at a predetermined angle relative to the feed support frame 200. The mounting end 220 of the feed support frame 200 is configured with a reserved space.

[0046] The feed assembly 400 includes a feed 410, a power amplifier 420 connected to the feed 410, and a rotating shaft disposed at the connection between the feed 410 and the power amplifier 420. The rotating shaft is connected to the mounting end 220 of the feed support frame 200, and the feed 410 and the power amplifier 420 are configured to rotate with the rotating shaft.

[0047] The locking member 300 is connected to the rotating shaft configuration, and is used to make the feed assembly 400 stay in the first position and the second position respectively. Among them, in the present application, the position where the feed 410 faces the reflector antenna 100 and can work normally with the reflector antenna 100 is defined as the first position. The position where the power amplifier 420 is accommodated in the reserved space of the mounting end 220 is defined as the second position. This situation is applicable to the case where the feed 410 is located outside the end of the mounting end 220, and only the power amplifier 420 is accommodated in the reserved space. Alternatively, when the power amplifier 420 and the feed 410 are both accommodated in the reserved space at the mounting end 220, the position when the power amplifier 420 and the feed 410 are both rotated to the reserved space is defined as the second position. In the second position, the reflector antenna 100 and the feed support frame 200 are in a folded state, and the reflector antenna 100 just covers or is slightly shorter than the length of the feed support frame 200 from the pivot end 210 to the mounting end 220.

[0048] In the above implementation process, the feed assembly 400 is rotatably set at the end of the feed support frame 200, rather than being detachable. Since the feed 410 is always limited to the end of the feed support frame 200, its position will not change, and there will be no change in the installation position. The locking member 300 fixes the feed assembly 400 in the first position, that is, the angle of the feed 410 toward the reflector antenna 100 is always at the same position when the feed 410 is working. Since the position and angle of the feed 410 can always be located at the specified position, the satellite communication portable station in this application can achieve accurate adjustment of the position and angle of the feed 410, avoiding subsequent maintenance. At the same time, the feed support frame 200 in the present application is configured with a reserved space that can accommodate the power amplifier 420 or the power amplifier 420 and the feed 410. Since the volume of the feed 410 is usually small, when the reflector antenna 100 and the feed support frame 200 are in a folded state, the power amplifier 420 and the feed 410 can be almost considered to be completely stored in the reserved space of the feed support frame 200, so that the volume of the satellite communication portable station is only the volume of the reflector antenna 100 and the feed support frame 200, thereby achieving the minimum envelope for collection and carrying, making it more convenient to carry.

[0049] Figure 2 for Figure 1 Another visual structural diagram of the satellite communication portable station shown in FIG. Figure 1 and Figure 2The feed support frame 200 includes a first feed support arm and a second feed support arm which are arranged in parallel and have a predetermined distance. The first feed support arm and the second feed support arm are connected by a pivot at the end of the pivot end 210. The reflector antenna 100 is rotatably connected to the pivot.

[0050] The reflector antenna 100 and the feed support frame 200 are connected by a pivot rotation to achieve mutual folding. When the satellite communication portable station is in operation, the reflector antenna 100 and the feed support frame 200 need to maintain a predetermined flip angle. Maintaining a predetermined flip angle between the reflector antenna 100 and the feed support frame 200 can be achieved in at least two of the following forms: First, there is friction between the reflector antenna 100 and the pivot, and the friction can prevent the reflector antenna 100 from rotating relative to the pivot after the reflector antenna 100 is in a predetermined position. Second, the reflector antenna 100 is connected to the pivot in a smooth rotation, and the reflector antenna 100 is fixed by a support rod, see Figure 1 The support rod is arranged on the first feed support arm (or the second feed support arm), and the support rod 500 maintains a predetermined flip angle between the reflector antenna 100 and the feed support frame 200. The support rod 500 may be a rod body with a predetermined length, or a hydraulic rod or a pneumatic rod capable of adjusting the length of the rod body.

[0051] It should be noted that the present application does not make any specific limitation on how to achieve maintaining a predetermined flip angle between the reflector antenna 100 and the feed support frame 200. Any structure that can achieve mutual rotation between the reflector antenna 100 and the feed support frame 200 and keep the reflector antenna 100 and the feed support frame 200 fixed at a predetermined flip angle falls within the protection scope of the present application.

[0052] See also Figure 2 The end of the first feed arm 230 located at the mounting end 220 is adjacent to the end of the second feed arm 240 located at the mounting end 220 by a predetermined distance, and the gap between the first feed arm and the second feed arm near the mounting end 220 constitutes a reserved space at the mounting end of the feed support frame 200. Figure 1In a possible implementation, the end of the first feed arm located at the mounting end 220 and the end of the second feed arm located at the mounting end 220 are both provided with a mounting plate 221 having a protruding portion. In a possible implementation, the connection between the power amplifier 420 and the feed source is arranged in the space between the two mounting plates 221. Since the mounting plate 221 has only a plate body of a predetermined thickness and has a space extending downward relative to the feed support frame 200, the structure of the mounting plate 221 can make the space between the first feed arm and the second feed arm close to the mounting end 220 as large as possible, so that the feed support frame 200 occupies a smaller space. At the same time, the cross-section of the connection between the mounting plate 221 and the power amplifier 420 and the feed source is in surface contact. When the mounting plate 221 is connected to the connection between the power amplifier 420 and the feed source, the connection between the power amplifier 420 and the feed source will not be damaged. At the same time, the structure of the mounting plate 221 can also increase the installation area on both sides of the mounting end of the feed support frame 200, which is conducive to the installation of various structures.

[0053] It should be noted that the structure in which the feed support frame 200 includes the first feed support arm 230 and the second feed support arm 240 which are arranged in parallel and have a predetermined distance is only exemplary. The feed support frame 200 in the present application may also adopt a plate structure, see Figure 3 , a first groove 250 capable of accommodating the pivot is provided at one end of the plate body, and a second groove 260 is provided at the other end of the plate body. The second groove 260 is longer than the first groove 250 in extending into the plate body to form the above-mentioned reserved space, and the thickness of the side plates on both sides of the second groove 260 can be relatively thin, so that the two ends on the side of the installation end of the feed support frame 200 can be close to each other. The material of the plate body includes but is not limited to iron plate, stainless steel plate, etc.

[0054] In a possible implementation, the rotating shaft 600 that connects the feed assembly 400 to the feed support frame 200 includes a first rotating shaft. The first rotating shaft passes through the connection between the feed and the power amplifier 420, and one end of the first rotating shaft passes through a predetermined length of the outer side of the first feed support arm 230. The other end of the first rotating shaft passes through a predetermined length of the outer side of the second feed support arm 240.

[0055] In another possible implementation, the rotating shaft 600 that connects the feed assembly 400 to the feed support frame 200 includes a second rotating shaft and a third rotating shaft. The second rotating shaft and the third rotating shaft are respectively arranged on both sides of the connection between the feed and the power amplifier 420 and are fixedly connected to the connection between the feed and the power amplifier 420. The axis of the second rotating shaft and the third rotating shaft coincide. One end of the second rotating shaft passes through a predetermined length of the outer side surface of the first feed support arm 230; one end of the third rotating shaft passes through a predetermined length of the outer side surface of the second feed support arm 240.

[0056] In a possible implementation, an external thread is provided on the rotating shaft 600 of the above two structures. The locking member 300 is a threaded locking member 300, which is screwed into the end of the rotating shaft 600 located on the outer side of the first feed support arm 230 and the end located on the outer side of the second feed support arm 240, respectively, and the feed assembly 400 is clamped and fixed by shortening the distance between the first feed support arm 230 and the second feed support arm 240. The feed assembly 400 is clamped and fixed at the first position or the second position by the threaded locking member 300. The threaded locking member 300 in the present application includes but is not limited to a nut, a screw or a cam.

[0057] In a possible implementation, a mechanical stopper is provided on the rotating shaft 600, and a stopper groove is provided on the first feed support arm 230 corresponding to the mechanical stopper, which is used to cooperate with the mechanical stopper to limit the feed assembly 400 in the second position. Specifically, the mechanical stopper can be an elastic boss provided on the surface of the rotating shaft 600, and the stopper groove is provided on the side wall of the through hole of the mounting plate 221 for passing the rotating shaft 600, and the stopper groove is close to the inner side surface of the mounting plate 221 and the length in the axial direction of the rotating shaft 600 is greater than the length of the elastic boss in the axial direction of the rotating shaft 600. This design is to enable the elastic boss to move a distance in the axial direction of the rotating shaft 600 when an external force is applied to the first feed support arm 230 and the second feed support arm 240 to bring the two closer together, so as to prevent the elastic boss from preventing the first feed support arm 230 and the second feed support arm 240 from being fixed close to each other.

[0058] It should be noted that the limit groove may also be provided only on the second feed arm 240, or the limit groove may be provided on both the first feed arm 230 and the second feed arm 240, and the limit groove on the first feed arm 230 and the limit groove on the second feed arm 240 are symmetrical about the longitudinal center section of the feed support frame 200.

[0059] In the above implementation process, the design of the mechanical limiter and the limit slot is used to determine whether the portable satellite communication station has reached the position of the storage state. When the portable satellite communication station needs to be stored, the feed source and the power amplifier 420 rotate together toward the reflector antenna 100, and the reflector antenna 100 rotates and buckles toward the feed source. When the mechanical limiter of the shaft 600 reaches the limit slot of the feed source support arm, the shaft 600 can no longer rotate. At this time, the threaded locking member 300 is screwed in and locked to realize the storage of the portable satellite communication station. See Figure 4 .

[0060] When the structure of the rotating shaft 600 adopts the structural form of the first rotating shaft, in a possible implementation, a first through hole is provided on the rotating shaft 600, and the first through hole extends along the axis of the rotating shaft 600 and is at a predetermined distance from the axis of the rotating shaft 600. Second through holes are provided on the first feed support arm 230 and the second feed support arm 240, respectively, and when the feed assembly 400 stays at the first position, the first through hole communicates with the second through hole. First photoelectric sensors are provided on both sides of the second through hole.

[0061] In the above implementation process, the rotation angle of the rotating shaft 600, that is, the rotation angle of the feed assembly 400, is determined by respectively opening the second through holes on the first feed arm 230 and the second feed arm 240 at positions corresponding to the first position where the feed assembly 400 needs to stay, and opening the first through hole on the rotating shaft 600. When the first through hole is connected to the second through hole, the emission light of the first photoelectric sensor on the first feed arm 230 passes through the first through hole to reach the receiver of the first photoelectric sensor on the second feed arm 240, that is, the feed assembly 400 rotates to the first position, at which time the rotation of the feed assembly 400 is stopped, and the first feed arm 230 and the second feed arm 240 are brought close to each other by the threaded locking member 300 to fix the feed assembly 400. After the feed assembly 400 is fixed, subsequent star search procedures and other operations can be performed.

[0062] When the structure of the rotating shaft 600 adopts the structural form of the second rotating shaft and the third rotating shaft, in a possible implementation, a third through hole is provided at the end of the rotating shaft 600 extending from the first feed support arm 230, and the third through hole is perpendicular to the axial direction of the rotating shaft 600. A second photoelectric sensor 700 matching the third through hole is provided on the outer side surface of the first feed support arm 230.

[0063] In the above implementation process, since the second rotating shaft and the third rotating shaft are coaxial and have the same rotation angle, a third through hole is provided at the end of the rotating shaft 600 extending from the first feed arm 230, wherein the positional relationship and the light correspondence relationship between the second photoelectric sensor 700 and the third through hole are set such that when the feed assembly 400 is located at the first position, the light emitted by the second photoelectric sensor 700 just passes through the third through hole and is emitted along the axis of the third through hole. In this embodiment, the transmitter and the receiver of the second photoelectric sensor 700 are respectively arranged on both sides of the third through hole. When the receiver of the second photoelectric sensor 700 receives the transmission signal, it indicates that the second rotating shaft rotates to the first position, that is, the feed assembly 400 reaches the first position. At this time, the rotation of the feed assembly 400 is stopped, and the first feed arm 230 and the second feed arm 240 are brought close to each other by the threaded locking member 300 to fix the feed assembly 400. After the feed assembly 400 is fixed, subsequent star search procedures and other operations can be performed.

[0064] In a possible implementation, a fourth through hole is provided at the end of the shaft 600 extending from the second feed arm 240, and the fourth through hole is perpendicular to the axis of the shaft 600. A third photoelectric sensor is provided on the outer side of the second feed arm 240 to match the fourth through hole.

[0065] In the above implementation process, the working principle of the fourth through hole and the third photoelectric sensor for determining whether the third rotating shaft reaches the first position is the same as the working principle of the third through hole and the second photoelectric sensor 700 for determining whether the second rotating shaft reaches the first position, which will not be described here. The fourth through hole and the third photoelectric sensor are provided to assist in detecting whether both ends of the rotating shaft are simultaneously located at the first position to ensure that the rotation angles of the two ends of the rotating shaft are the same.

[0066] It should be noted that the first photoelectric sensor, the second photoelectric sensor 700 and the third photoelectric sensor in the present application may also be sensors such as distance sensors or incident laser photoelectric sensors.

[0067] The following is an explanation of how to use the satellite communication portable station:

[0068] When the portable satellite communication station is required to operate, the reflector antenna 100 is opened, and after the feed assembly 400 is rotated to the first position, the first photoelectric sensor or the second photoelectric sensor 700 and the third photoelectric sensor combination can be used to further determine whether the feed assembly 400 has reached the first position. After determining that the feed assembly 400 is located at the first position, the locking member 300 is tightened, and the feed assembly 400 and the reflector antenna 100 perform the next step of the satellite search procedure and finally align with the satellite. When the portable satellite communication station needs to be closed, the feed assembly 400 is rotated in the opposite direction to the second position, and the mechanical limiter can be used to further determine whether the feed assembly 400 has reached the second position. After determining that the feed assembly 400 has reached the second position, the reflector antenna 100 rotates toward the feed support frame 200 until the reflector antenna 100 and the feed support frame 200 are close together and reach the collection state.

[0069] It can be seen from the above technical solution that the present application adds a rotating shaft structure at the place where the feed source and the power amplifier 420 are connected, and the rotating shaft is used to realize the overall rotation of the feed assembly 400 including the feed source and the power amplifier. The feed assembly 400 is rotatably set at the end of the feed support frame 200, rather than being detachable. Since the feed source is always limited to the end of the feed support frame 200, its position will not change, and there will be no change in the installation position. At the same time, the feed support frame 200 in the present application is configured with a reserved space that can accommodate the power amplifier 420 or the power amplifier 420 and the feed source, so that the volume of the satellite communication portable station is only the volume of the reflector antenna 100 and the feed support frame 200, thereby achieving the minimum envelope for collection and carrying, and it is more convenient to carry.

[0070] In a second aspect, the present application also provides a satellite communication system, including a satellite communication portable station, a modem and a controller of the above structure, wherein the modem is connected to the power amplifier 420 in the satellite communication portable station via a radio frequency cable, and the controller is connected to the communication portable station.

[0071] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
