[0072] The accompanying drawings have illustrated specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to specific embodiments. Detailed Implementation

[0073] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0074] Figure 1 This is a schematic diagram illustrating a scenario for adjusting the antenna attitude provided in this application. Figure 1 As shown, the application scenario provided in this application embodiment may include a vehicle and a satellite. A control device 101 is installed in the vehicle, and a vehicle-mounted satellite antenna 102 is installed on the outside of the vehicle. The vehicle-mounted satellite antenna 102 may include a base, a horizontal tray, an antenna tray, an antenna, and a transmission device. The base of the vehicle-mounted satellite antenna 102 may be placed on the top of the vehicle, and the base is parallel to the top of the vehicle.

[0075] The control device 101 can be an electronic device. The control device 101 can receive satellite connection commands, which may include satellite position information. Based on the satellite position information, the current relative position between the vehicle-mounted satellite antenna and the satellite can be determined, as well as the horizontal tray's horizontal position. The current attitude information of the antenna tray is acquired, and based on the current relative position and attitude information, the current attitude of the antenna tray is adjusted to obtain the target attitude of the antenna tray, thereby aligning the antenna with the satellite.

[0076] In existing technologies, vehicle-mounted satellite antennas can include variable-focal-length elliptical wave antennas and array antennas, which can receive satellite signals while the vehicle is in motion. However, the angle at which vehicle-mounted satellite antennas can locate satellites is limited, requiring the vehicle to adjust its direction to improve the connection between the antenna and the satellite, resulting in low efficiency in adjusting the antenna's attitude.

[0077] The antenna attitude adjustment method provided in this application can determine the current relative position between the vehicle-mounted satellite antenna and the satellite according to the satellite connection command, obtain the current attitude information of the antenna tray, and directly control and adjust the antenna tray and horizontal tray of the vehicle-mounted satellite antenna based on the current relative position and current attitude information, thereby realizing real-time monitoring of the vehicle-mounted satellite antenna, automatically adjusting the attitude of the vehicle-mounted satellite antenna, and improving the efficiency of antenna attitude adjustment.

[0078] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will be described below with reference to the accompanying drawings.

[0079] Figure 2 This is a schematic diagram of the structure of a vehicle-mounted satellite antenna provided in an embodiment of this application. Please refer to [link / reference]. Figure 2 The current attitude of the vehicle-mounted satellite antenna when the vehicle is on flat ground. The vehicle-mounted satellite antenna may include an antenna, an antenna tray, a horizontal tray, a horizontal tray bracket, a counterweight device, a base, and a transmission device.

[0080] The base can be fixed to the top of the vehicle, parallel to the top of the vehicle, and can rotate horizontally with a rotation angle of 360 degrees.

[0081] The horizontal tray can be placed above the base using two first supports. One end of each first support is fixedly connected to the base, and the other end is a ring. Each side of the horizontal tray support has a connecting shaft, which is inserted into the ring of the first support, allowing the horizontal tray support to rotate in the vertical plane. When the horizontal tray is placed above the support, the vertical rotation of the support drives the horizontal tray to rotate, allowing the horizontal tray to rotate 360 ​​degrees in the horizontal plane.

[0082] A counterweight device is fixed below the horizontal pallet support. The counterweight device includes a sensor, which can be used to obtain the current posture of the horizontal pallet support.

[0083] The sensor can be a built-in gyroscope, accelerometer, magnetometer, or photoelectric encoder, etc.

[0084] The antenna tray is positioned above a horizontal tray via two secondary supports. One end of each secondary support is fixedly connected to the horizontal tray, while the other end is a ring. Each side of the antenna tray has a connecting shaft that inserts into the ring of the secondary support, allowing the antenna tray to rotate in both the horizontal and vertical planes. Because the antenna tray is fixed above the horizontal tray via the secondary supports, rotation of the horizontal tray in the horizontal plane causes the antenna tray to rotate in the same plane. The antenna is fixed to the antenna tray, and rotation of the antenna tray causes the antenna to rotate, allowing the antenna to rotate both horizontally and vertically.

[0085] The transmission mechanism can control the rotation of the base and horizontal tray in the horizontal plane, and the rotation of the antenna tray in the vertical plane. This allows for free adjustment of the antenna alignment with the satellite, improving the efficiency of antenna attitude adjustment.

[0086] The appearance of the vehicle-mounted satellite antenna can be a shark fin or a mushroom top, etc., and this application does not limit the specific shape of the appearance.

[0087] Figure 3 This is a flowchart illustrating a method for adjusting antenna attitude provided in this application. Please refer to section 3. This method may include:

[0088] S301, Receive satellite connection command.

[0089] The execution subject of this application embodiment can be a control device, or it can be an antenna attitude adjustment device set in the control device. It can be implemented by software or by a combination of software and hardware.

[0090] Satellite connection commands can be used to establish a communication connection between the vehicle-mounted satellite antenna and a satellite. These commands can include satellite location information.

[0091] Vehicle-mounted satellite antennas may include antennas, antenna trays, horizontal trays, and bases.

[0092] S302. Determine the current relative position between the vehicle-mounted satellite antenna and the satellite based on the satellite position information.

[0093] Satellite position information can be ephemeris data, which is time-series data describing the satellite's position and velocity in orbit.

[0094] The location information at each moment can be determined using satellite location information.

[0095] Furthermore, the current satellite position can be determined based on satellite position information, the current vehicle position can be obtained, and the current relative position can be determined based on the current satellite position and the current vehicle position.

[0096] For example, the current relative position could be that the satellite is in front of the vehicle, behind the vehicle, to the side of the vehicle, or directly above the vehicle.

[0097] S303. Determine the current status of the horizontal pallet.

[0098] The current state can include a tilted state and a horizontal state.

[0099] Since vehicles may go uphill or downhill while driving, the base of the vehicle-mounted satellite antenna is parallel to the top of the vehicle. The vehicle-mounted satellite antenna will tilt along with the vehicle, so the current state of the horizontal tray is tilted. The antenna can be adjusted to a horizontal state using the horizontal tray.

[0100] The horizontal tray can be adjusted to a horizontal position in the following two ways:

[0101] Option 1: The vehicle-mounted satellite antenna may include a base, a horizontal tray bracket, a horizontal tray, and two first brackets. For connection details, please refer to [reference needed]. Figure 2 .

[0102] It can obtain the current vehicle posture; determine the third rotation angle of the base based on the current vehicle posture; control the base to rotate by the third rotation angle, so as to drive the horizontal pallet bracket to rotate by the third rotation angle, and adjust the current state of the horizontal pallet to a horizontal state.

[0103] The current vehicle posture can be horizontal or tilted. The tilted state can include the vehicle's tilt direction and tilt angle.

[0104] The third rotation angle can ensure that the rotated horizontal tray is in a horizontal state.

[0105] For example, assuming the vehicle is going uphill, its current orientation can be facing forward and tilted upwards by 30 degrees. A third rotation angle can be determined, and the base can be controlled to rotate by this third rotation angle to keep the horizontal tray level.

[0106] Method 2: The vehicle-mounted satellite antenna includes a base, a horizontal tray, and a first support. The first support can lift the horizontal tray and place it on the base at the center of gravity of the horizontal tray. When the base is tilted, the horizontal tray can remain horizontal due to the center of gravity.

[0107] Compared to method two, method one improves the stability of the vehicle-mounted satellite antenna and the accuracy of controlling the attitude of the vehicle-mounted antenna.

[0108] Furthermore, the vehicle-mounted satellite antenna may also include a counterweight device, which may be fixed to the horizontal tray or the horizontal tray support.

[0109] S304. When the current state is horizontal, obtain the current attitude information of the antenna tray.

[0110] The sensor located under the horizontal tray can determine whether the current state is horizontal. After the horizontal tray is adjusted to a horizontal state, the current attitude information of the antenna tray can be obtained.

[0111] The current attitude information of the antenna tray can be obtained through sensors. The current attitude information can include the current pitch angle and current azimuth angle of the antenna tray.

[0112] The corresponding sensors can be placed under the horizontal tray and antenna tray bracket, which can improve the accuracy of adjusting the vehicle-mounted satellite antenna.

[0113] S305. Based on the current relative position and current attitude information, adjust the current attitude of the antenna tray to obtain the target attitude of the antenna tray so as to align the antenna with the satellite.

[0114] The target attitude of the antenna tray can be determined as follows: Based on the current relative position, determine the first rotation angle of the horizontal tray and the second rotation angle of the antenna tray; adjust the horizontal tray and the antenna tray according to the first rotation angle and the second rotation angle to obtain the first attitude; fine-tune the first attitude to obtain the target attitude.

[0115] The azimuth angle of the two second supports, antenna tray, and antenna can be adjusted by the first rotation angle, so that the antenna turns toward the direction of the satellite. The antenna tray can be rotated vertically by the second rotation angle to adjust the elevation angle of the antenna, so that the antenna is aligned with the satellite.

[0116] After adjusting the vehicle-mounted satellite antenna to the target orientation, the azimuth information of the vehicle-mounted satellite antenna can be locked.

[0117] The antenna attitude adjustment method provided in this application embodiment can determine the current relative position between the vehicle-mounted satellite antenna and the satellite according to the satellite connection command, obtain the current attitude information of the antenna tray, and directly control and adjust the antenna tray, horizontal tray, and base of the vehicle-mounted satellite antenna based on the current relative position and current attitude information, thereby realizing automated adjustment of the attitude of the vehicle-mounted satellite antenna and improving the efficiency of antenna attitude adjustment.

[0118] Figure 4 A flowchart illustrating another antenna attitude adjustment method provided in this application. Figure 4 As shown, in this embodiment... Figure 3 Based on the embodiments, the method for adjusting the antenna attitude is described in detail, which includes:

[0119] S401. Based on the current relative position, determine the first rotation angle of the horizontal tray and the second rotation angle of the antenna tray.

[0120] Furthermore, the first current angle of the horizontal tray can be obtained, and the first rotation angle can be determined based on the first current angle of the horizontal tray and the current relative position.

[0121] Furthermore, the second current angle of the antenna tray can be obtained, and the second rotation angle can be determined based on the second current angle of the antenna tray and the current relative position.

[0122] The first and second current angles can be obtained through sensors.

[0123] In its initial state, the vehicle-mounted satellite antenna has its two first supports aligned in the first straight line.

[0124] S402. Generate a first control command based on the first rotation angle and the second rotation angle.

[0125] The first control command can be used to control the rotation of the horizontal tray and the antenna tray.

[0126] S403, Send the first control command to the transmission device.

[0127] S404. The horizontal tray and the antenna tray are rotated by the transmission device to obtain the first attitude.

[0128] The transmission device can control the horizontal tray to rotate 360 ​​degrees on the horizontal plane and can control the antenna tray on the vertical plane. Rotate.

[0129] S405. In the first posture, establish a communication connection between the vehicle-mounted satellite antenna and the satellite, and receive satellite strength signals through the vehicle-mounted satellite antenna.

[0130] Satellite signal strength can be expressed as a Received Signal Strength Indicator (RSSI), which is a measure of radio signal strength. RSSI values ​​are typically expressed in decibels per milliwatt (dBm) and reflect the signal power received by the receiving antenna.

[0131] S406. Based on the satellite strength signal, determine the first adjustment angle of the horizontal tray and the second adjustment angle of the antenna tray.

[0132] If the satellite signal strength is lower than the preset signal strength, the horizontal tray and antenna tray can be fine-tuned according to the satellite signal strength.

[0133] It is worth noting that either the horizontal tray or the antenna tray can be adjusted, or both can be adjusted together.

[0134] It can determine the difference between satellite intensity information and preset intensity signals, and determine the degree of adjustment based on the difference.

[0135] S407. Based on the first adjustment angle and the second adjustment angle, fine-tune the first attitude to obtain the target attitude.

[0136] The vehicle can receive satellite signals while driving and monitor the satellite signal strength in real time. Based on the satellite signal strength, the base, level tray, and antenna tray can be continuously adjusted to improve the flexibility of antenna attitude adjustment.

[0137] The antenna attitude adjustment method provided in this application embodiment can adjust the antenna's azimuth angle by controlling the horizontal tray to rotate horizontally, and adjust the antenna's elevation angle by controlling the antenna tray to rotate vertically, thereby achieving automated adjustment of the vehicle-mounted satellite antenna's attitude and improving the efficiency of antenna attitude adjustment. Simultaneously, it can acquire satellite strength signals in real time and adjust the antenna attitude based on the satellite signal strength, achieving real-time monitoring and adjustment of the vehicle-mounted satellite antenna and improving the flexibility of antenna attitude adjustment.

Figure 5 In this embodiment Figure 2 Based on the embodiments, the attitude of the vehicle-mounted satellite antenna during vehicle movement is described in detail.

[0139] The vehicle is currently in an uphill position, with the satellite directly above it. Since the onboard satellite antenna is located on the vehicle, its base tilts with the vehicle body. Sensors can monitor the antenna's current attitude. A transmission mechanism can control the base to rotate, and under gravity, adjust the horizontal tray back to a horizontal position, ensuring the antenna and tray are level. At this point, the satellite is directly above the vehicle, and the antenna can receive satellite signals.

[0140] Figure 6 This is a schematic diagram illustrating the attitude of another vehicle-mounted satellite antenna provided in an embodiment of this application. Please refer to... Figure 6 The embodiments of this application are in Figure 2 Based on the embodiments, the attitude of the vehicle-mounted satellite antenna during vehicle movement is described in detail.

[0141] The vehicle is currently in an uphill position, with the satellite positioned in front of the vehicle. Sensors can monitor the current attitude of the onboard satellite antenna. A transmission mechanism can control the base to rotate by a third angle, and under gravity, adjust the horizontal tray back to a horizontal position, ensuring the antenna and antenna tray are level.

[0142] The current relative position is that the satellite is in front of the vehicle. The horizontal tray can be rotated by the transmission device by the first rotation angle, and the antenna tray can be rotated by the second rotation angle to adjust the antenna to the target attitude, that is, to face the satellite, so that the antenna can receive the satellite signal with the greatest strength.
