[0029] First embodiment

[0030] See also Figure 1 to Figure 4The present invention provides a remote sensing integrated portable antenna, including a feed system 101, a main reflector 102, a radio frequency component 103, a polarization stepping motor 104, a control box 105, a driving component 106, a tripod 107 and a power amplifier 108, wherein the feed system 101 is arranged on the main reflector 102, the radio frequency component 103 is arranged on one side of the main reflector 102, and the polarization stepping motor 104 is used to adjust the angle of the polarization axis; the tripod 107 includes a sliding ring, a support column, a rotating rod, a limiting rod and a base, the driving component 106 is connected to the main reflector 102, the support column supports the driving component 106, the sliding ring is slidably arranged on the support column, the base is fixed to the bottom of the support column, the limiting rod is rotatably connected to the base, the rotating rod is rotatably connected to the limiting rod and rotatably connected to the sliding ring, and the power amplifier 108 is arranged on one side of the support column.

[0031] In this embodiment, the feed system 101, as the heart of the antenna, is precisely positioned and installed on the main reflector 102, responsible for receiving or transmitting signals. It works in conjunction with the main reflector 102 to ensure maximum gain and minimum distortion of the signal. The main reflector 102 is made of lightweight but sturdy materials, has excellent electromagnetic wave reflection characteristics, and can focus the radio waves emitted by the feed into a narrow beam, thereby improving the effectiveness of long-distance communication. The radio frequency component 103 is located on one side of the main reflector 102 and contains a series of electronic components for processing the received high-frequency signals. These components can filter, amplify and convert signals for further processing and analysis. At the same time, in order to adapt to signals with different polarization directions, the system is equipped with a polarization stepper motor 104, which can accurately adjust the angle of the polarization axis to ensure the best signal reception quality. The core of the control system is the control box 105, which integrates all the necessary circuits and processors to monitor and operate various parts of the entire antenna system. The control box 105 coordinates the actions of various components through pre-programmed instructions, such as adjusting the polarization angle, tracking satellite positions, etc., so that users can easily complete complex settings.

[0032] The drive assembly 106 is directly connected to the main reflector 102 and is supported by support columns. This assembly includes a power unit and a transmission mechanism that work together to change the direction of the main reflector 102 to ensure that the antenna is always aimed at the target satellite.

[0033] The sliding ring can move freely on the support column; the base is firmly fixed to the bottom of the support column, providing a stable base. In addition, the limit rod is rotatably connected to the base, and the rotating rod is rotatably connected to both the limit rod and the sliding ring, so that the sliding ring can drive the rotating rod and the limit rod to rotate when moving up and down, so that the limit rod can be opened when in use, and the limit rod can be rotated close to the support column when moving to facilitate movement, thereby making the movement more portable.

[0034] The power amplifier 108 is mounted on one side of the support column and is used to boost the signal before it is transmitted, ensuring that the signal is strong enough to reach a distant destination. The power amplifier 108 is essential for improving communication distance and reliability, especially in severe weather conditions or when a large area needs to be covered.

[0035] The driving assembly 106 includes an X-axis driving module and a Y-axis driving module. The X-axis driving module is used to drive the main reflecting surface 102 to rotate along the X-axis; the Y-axis driving module is used to drive the main reflecting surface 102 to rotate along the Y-axis.

[0036] The X-axis drive module includes a mounting seat 109, an X-axis drive motor 110 and a rotating shell 111, wherein the mounting seat 109 is fixed to the top of the support column, the output end of the X-axis drive motor 110 is connected to the mounting seat 109, and the rotating shell 111 is fixed to the X-axis drive motor 110; the Y-axis drive module includes a Y-axis motor 112 and a rotating plate 113, wherein the Y-axis motor 112 is fixed to the rotating shell 111, and the rotating plate 113 is connected to the output end of the Y-axis motor 112.

[0037] The mounting base 109 serves as a fixed foundation for the entire drive system. The mounting base 109 is firmly fixed on the top of the support column, providing a stable mounting platform for the X-axis drive module.

[0038] The X-axis drive motor 110 is the core power source for realizing the horizontal rotation of the main reflective surface 102. Its output end is directly or through an appropriate transmission mechanism connected to the mounting seat 109. When the motor is started, it can generate sufficient torque to overcome friction and other resistances, and smoothly drive the main reflective surface 102 to rotate along the X-axis direction. The rotating shell 111 is fixed around the X-axis drive motor 110. The rotating shell 111 not only protects the internal motor from the influence of the external environment, but also itself constitutes the basis of a rotating structure, allowing the Y-axis drive module to be installed thereon and rotate with it.

[0039] The Y-axis motor 112 is fixed to the rotating shell 111, which means that it can rotate in the horizontal direction together with the X-axis drive module. The Y-axis motor 112 is designed to provide precise angle control so that the main reflector 102 can be accurately positioned to the required altitude angle. The rotating plate 113 is connected to the output end of the Y-axis motor 112, and the rotating plate 113 directly carries the main reflector 102. When the Y-axis motor 112 is working, it drives the rotating plate 113 to swing up and down along the Y-axis direction together with the main reflector 102, thereby changing the elevation angle of the antenna.

[0040] There is a close cooperation between the two drive modules. First, the X-axis drive module realizes omnidirectional scanning in the horizontal direction through the action of its motor, while the Y-axis drive module provides angle adjustment in the vertical direction. The two together form a two-dimensional spatial coordinate system, which allows the main reflector 102 to move freely in a large range, ensuring that the satellite can maintain the best alignment state no matter where it is.

[0041] The sliding ring includes a sliding ring body 114 and a limiting plate 115, wherein the limiting plate 115 has a slot 117, the limiting plate 115 is rotatably connected to the support column and is located on one side of the support column, and the sliding ring body 114 has a clamping rod 116, which is fixed to the sliding ring body 114 and matches the slot 117.

[0042] The sliding ring body 114 is the main structural part of the sliding ring, and is designed to be able to slide freely on the support column. Its interior is smooth and specially treated to reduce friction, making the sliding smoother. The limit plate 115 is rotatably connected to the support column and is located on one side of the support column. The limit plate 115 is provided with a card slot 117 for matching with the card rod 116 on the sliding ring body 114. This design not only ensures that the sliding ring can move up and down along the support column within a certain range, but also can realize the function of fixing the position through the cooperation of the card slot 117 and the card rod 116, preventing the sliding ring from accidentally slipping or shifting.

[0043] The support rod and the limiting rod are rotatably connected via a connecting head 118 , and a stabilizing seat is provided on the connecting head 118 .

[0044] In order to increase the stability of the entire system, the support rod and the limit rod are connected by rotation through a connector 118:

[0045] The connector 118 serves as a bridge between the support rod and the limit rod, allowing a certain degree of rotational freedom between the two. At the same time, a stabilizing seat is provided on the connector 118 to further enhance the stability of the connection. The stabilizing seat is used to maintain the balance and stability of the antenna system.

[0046] The stabilizing seat includes a stabilizing seat body 119 , an adjusting rod 120 and a fixing seat 121 . The stabilizing seat body 119 is connected to the supporting rod and the limiting rod. The adjusting rod 120 is threadedly connected to the stabilizing seat body 119 . The fixing seat 121 is arranged at the bottom of the adjusting rod 120 .

[0047] The stabilizing seat body 119 is the core structure of the stabilizing seat, and it firmly connects the support rod and the limit rod together. The stabilizing seat body 119 not only has to withstand forces from all directions, but also has to ensure the safety and reliability of all connection points.

[0048] The adjustment rod 120 is threadedly connected to the stabilizing base body 119, which means that the user can adjust the extension length of the adjustment rod 120 by rotating it, thereby fine-tuning the angle or height of the entire antenna system. Such a design increases the flexibility of the system and enables it to adapt to different application scenarios.

[0049] The fixing base 121 is arranged at the bottom of the adjusting rod 120 to fix the adjusting rod 120 to the ground or other solid foundations. The fixing base 121 is usually equipped with accessories such as anti-skid pads or screws to ensure that it will not move easily.

[0050] The stabilizing seat further includes an adjusting disk 122 , which is fixedly connected to the adjusting rod 120 and is located on the top of the adjusting rod 120 .

[0051] The adjustment disk 122 is mainly used to provide a comfortable grip point during manual operation, and is also convenient for observing the angle change of adjustment. In some cases, the adjustment disk 122 is marked with scales to help users control the adjustment amount more accurately.

[0052] The power amplifier 108 includes an amplifier body, a heat dissipation fan and a protective cover. The protective cover is arranged on one side of the amplifier body, and the heat dissipation fan is arranged inside the protective cover.

[0053] The amplifier body integrates high-performance RF amplification circuits and other necessary electronic components. These components are precisely tuned to significantly increase the power level of the signal without adding too much noise. The amplifier body usually adopts a compact design to meet the miniaturization requirements of portable devices while ensuring its stability at high operating frequencies.

[0054] The cooling fan is integrated into the protective cover to form a closed but efficient cooling system. The design of the cooling fan takes into account the principles of aerodynamics to ensure that the airflow can evenly cover all hot areas of the amplifier body to remove excess heat. The fan speed can be dynamically adjusted based on the real-time data provided by the temperature sensor, which not only ensures sufficient cooling effect, but also reduces unnecessary energy consumption and noise.

[0055] Second embodiment

[0056] See also Figure 5 The present invention also provides a control algorithm for a portable antenna with integrated remote sensing and control, including:

[0057] S201 installs the antenna on the ground;

[0058] The technician needs to install the portable antenna system at the selected location. This step not only includes placing the antenna body firmly on the ground, but also ensures that the supporting structure (such as the tripod 107) is properly assembled and locked. In order to ensure the accuracy and stability of the installation, tools such as a level are usually used to assist in adjusting the base so that the entire antenna system remains as horizontal as possible in the initial state. In addition, on special terrain or uneven ground, additional pads or other auxiliary devices are required to compensate for the unevenness of the ground.

[0059] S202 obtains an inclinometer installed on the antenna mount to calibrate the stabilizing base so that the antenna remains vertical to the ground;

[0060] After installation, the next step is to precisely calibrate the stabilizer using the inclinometer mounted on the antenna mount. The inclinometer is a high-precision sensor that measures the angular deviation of the antenna relative to the ground in real time. The control system reads the inclinometer data and automatically adjusts the position of the stabilizer based on this information until the antenna is completely perpendicular to the ground. This process is iterative, meaning that the control system continuously fine-tunes until the required verticality standard is achieved. The purpose of this is to eliminate small angular errors that occur during installation and ensure that the antenna can accurately point to the target satellite in subsequent operations.

[0061] S203: acquiring dual Beidou data to control the driving component 106 to adjust the inclination angle of the main reflecting surface 102;

[0062] Once the antenna is calibrated to a vertical position, the next step is to use the high-precision position and time information provided by the dual BeiDou positioning system to guide the operation of the drive assembly 106. The dual BeiDou data not only contains information about the current geographical location of the antenna, but also provides real-time updates on the orbital parameters of the target satellite. Based on this data, the control system can calculate the exact azimuth and elevation angles that the antenna should point to, and adjust the horizontal and vertical inclinations of the main reflector 102 through the X-axis and Y-axis drive modules respectively, so that the antenna always maintains the best alignment with the target satellite. This automatic tracking function based on the satellite positioning system greatly improves the response speed and accuracy of the antenna, especially in a changing dynamic environment.

[0063] S204 uploads the data generated during the adjustment process to the host computer for abnormality analysis.

[0064] Finally, in order to ensure the long-term stable operation of the antenna system and to detect potential problems in a timely manner, all data related to antenna adjustment will be recorded and uploaded to the host computer (such as a remote server or a local computer) via wireless or wired connection. The host computer software will conduct an in-depth analysis of the data to check whether there are any abnormalities, such as unexpected movements, angle changes beyond the normal range, or other factors that affect performance. If an abnormality is detected, the system will generate an alarm to notify the user and provide diagnostic suggestions or automatically take corrective measures. In addition, by accumulating a large amount of historical data, trend analysis can also be performed to help optimize future operating strategies and technical maintenance plans.

[0065] What is disclosed above is only a preferred embodiment of the present invention, and it certainly cannot be used to limit the scope of rights of the present invention.
