DETAILED DESCRIPTION

[0014] The present invention will be further described below with reference to the accompanying drawings and examples.

[0015] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the fact that a better connection structure can be formed by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the invention can be combined interactively without conflicting with each other.

[0016] Reference Figure 1The figure shows a schematic diagram of the structure of an outdoor communication equipment adjustment system shown in an embodiment of the present application. The outdoor communication equipment adjustment system includes an antenna module, a signal detection module, a pan-tilt control module, a communication module and a signal data storage and display module. The antenna module includes an adjustable antenna, the pan-tilt control module includes an antenna control pan-tilt, and the adjustable antenna is installed on the antenna control pan-tilt. The communication module communicates with the indoor unit (IDU) or the BLE module with the user communication device (for example, the user's mobile phone), and the signal detection module is used to monitor the signal strength and signal quality in real time. When the signal detection module obtains the detection data, it can also transmit the detection data to the signal data storage and display module through the communication module. The signal data storage and storage module can display the signal strength and signal quality in the detection data in the form of a cloud map, such as a web page display, and can be displayed on the user communication device, such as an APP display.

[0017] In some embodiments, upon power-up, a signal detection module performs network signal detection. Specifically, the pan / tilt control module controls the antenna to perform an initial 360-degree scan horizontally and vertically to obtain signal strength and quality at each horizontal and vertical angle. The antenna can rotate in 1-degree increments, obtaining signal strength and quality at each horizontal and vertical angle. This results in 360 different sets of signal strength and quality across the 360-degree horizontal direction. Similarly, signal strength and quality at different vertical angles can be determined, and the angles with the best horizontal and vertical signal strength and quality are determined. The signal strength and quality data obtained by the signal detection module are transmitted to the pan / tilt control module via the communication module, allowing the pan / tilt control module to control and drive the pan / tilt to adjust the antenna direction based on the detection data (including signal strength and quality) from the signal detection module. A motor is provided on the antenna control pan / tilt. When the pan / tilt control module determines how to adjust the antenna based on the signal strength and quality, it controls the motor to adjust the antenna's direction and angle.

[0018] Reference Figure 2 As shown, it is a flow chart of an outdoor communication equipment adjustment method shown in an embodiment of the present application. The outdoor communication equipment adjustment method is applied to an outdoor communication equipment adjustment system. The outdoor communication equipment adjustment system includes an antenna module, a signal detection module, a pan-tilt control module and a communication module. The signal detection module establishes a communication connection with the antenna module and the pan-tilt control module through the communication module. The outdoor communication equipment adjustment method includes the following steps.

[0019] To facilitate understanding of the inventive concept of this application, the outdoor communication equipment is illustrated using an outdoor ODU (Outdoor Unit). The ODU is typically installed outdoors for wireless communication or data transmission. The ODU is typically used in conjunction with an IDU. The ODU is responsible for sending and receiving signals, while the IDU is responsible for signal processing and modulation / demodulation. The ODU and IDU are connected via transmission media such as feeders, forming a complete wireless communication system. In addition to being connected to the IDU, the ODU can also be connected to other communication equipment (e.g., base station controllers, switches, etc.) via transmission media such as optical fiber and coaxial cable to achieve signal transmission and processing.

[0020] S21, the adjustable antenna of the antenna module rotates according to the rotation direction and rotation angle, so that the signal detection module obtains the signal strength and signal quality corresponding to different vertical pitch angles of the adjustable antenna in each horizontal direction, and obtains a signal strength and quality set.

[0021] Among them, the ODU is equipped with an antenna control platform, which is connected to the antenna module through the antenna interface. Figure 2 In some embodiments, when the outdoor ODU device is powered on, it automatically initializes and uses the adjustable antenna and signal detection module of the antenna module to comprehensively scan and record the signal strength data and signal quality data in all directions and angles to obtain a signal strength and quality set, wherein the signal strength and quality set includes multiple signal strengths and multiple signal qualities. Specifically, after the initialization is completed, the signal detection module controls the antenna module to perform an initial 360-degree scan, including not only the vertical direction but also the horizontal direction, and records the signal strength and signal quality in each direction. Among them, the rotation angle of the adjustable antenna can be rotated in units of 1 degree. The signal detection module first detects and records the position of each horizontal angle, which corresponds to the signal strength and signal quality at different pitch angles in the vertical direction. Then, 360 sets of different signal strengths and signal qualities can be obtained in the horizontal 360-degree direction.

[0022] In some embodiments, to ensure data accuracy, the signal detection module may perform multiple sampling at each angle and calculate an average value to reduce random errors.

[0023] S22: The signal detection module sends the signal strength and quality set to the pan / tilt control module through the communication module.

[0024] The communication module communicates with the IDU or BLE module and the user's communication device to achieve communication connections between different modules of the outdoor communication equipment adjustment system. When the signal detection module obtains the signal strength and quality set, it can actively or passively transmit the signal strength and quality set to the pan-tilt control module, so that the pan-tilt control module can subsequently process the signal strength and quality set and adjust the adjustable antenna of the antenna module based on the signal strength and quality set.

[0025] S23, the pan / tilt control module determines an optimal signal angle and an optimal signal direction according to the signal strength and quality set.

[0026] In some embodiments, after receiving the signal strength and quality set, the PTZ control module may pre-process the signal strength data and signal quality data in the signal strength and quality set, such as data cleaning and noise removal. Then, based on the signal strength and quality algorithm, the direction and angle with the best signal strength and quality are selected.

[0027] In an optional embodiment, the pan / tilt control module determines the optimal signal angle and the optimal signal direction according to the signal strength and quality set, including: sorting the signal strengths corresponding to each vertical pitch angle in the signal strength and quality set from largest to smallest to obtain a signal strength angle list; Determine the interference intensity corresponding to each vertical pitch angle in the signal strength angle list; Averaging the signal strength angle list and the interference strength to obtain an average comprehensive score corresponding to each vertical pitch angle; Each vertical pitch angle is sorted from large to small according to the average comprehensive score to obtain the optimal signal angle and the optimal signal direction.

[0028] Generally speaking, a higher signal strength indicates better signal quality, but signal quality also depends on signal interference: signal quality = signal strength / interference strength. Therefore, the gimbal control module determines the direction and angle with the best signal strength and signal quality, referred to as the optimal signal angle and optimal signal direction, respectively. Signal strength is a key metric for evaluating signal quality. First, the signal strength corresponding to each vertical pitch angle in the signal strength and quality set is sorted from largest to smallest to determine which angles have the highest received signal strength. This sorting generates a signal strength angle list, where each element in the list contains a vertical pitch angle and its corresponding signal strength. When evaluating interference strength, multiple metrics (such as signal-to-noise ratio and bit error rate) influence interference strength. In this embodiment, sensitivity is the primary metric, representing the system's ability to receive and identify signals at a specific signal-to-noise ratio. Higher sensitivity indicates a weaker receiving device's resistance to interfering signals, resulting in a relatively higher interference strength. Next, the interference strength corresponding to each vertical pitch angle needs to be determined. After determining the signal strength and interference strength data, these two sets of data are averaged to obtain the average comprehensive score for each vertical pitch angle. Specifically, the average comprehensive score = (signal strength + interference strength) / 2. Each vertical pitch angle is then sorted from highest to lowest based on the average comprehensive score. The angle with the highest score is the optimal signal angle, and the corresponding direction is the optimal signal direction.

[0029] Through the above optional implementation, the PTZ control module preprocesses, sorts, evaluates interference intensity, and averages the signal strength and quality sets, effectively determining the optimal signal angle and direction. Specifically, by comprehensively considering signal strength and interference intensity, the accuracy and stability of signal reception are improved, optimizing communication performance. Furthermore, the impact of multiple quality indicators on interference intensity is considered, further enhancing the comprehensiveness and accuracy of signal quality assessment.

[0030] S24, the pan / tilt control module controls the antenna angle and the antenna direction of the adjustable antenna to adjust according to the optimal signal angle and the optimal signal direction.

[0031] In some embodiments, after determining the optimal signal angle and the optimal signal direction, the gimbal control module may adjust the current antenna angle and antenna direction of the adjustable antenna to the optimal signal angle and the optimal signal direction respectively.

[0032] In an optional embodiment, the method further comprises: The signal detection module obtains the current signal strength and the current signal quality of the adjustable antenna at the power-on moment, and transmits the current signal strength and the current signal quality to the pan / tilt control module; The PTZ control module determines whether to adjust the antenna angle and the antenna direction according to the current signal strength and the current signal quality; When determining to adjust the antenna angle and the antenna direction, the pan / tilt control module adjusts the antenna angle according to the optimal signal angle and adjusts the antenna direction according to the optimal signal direction.

[0033] In some embodiments, the gimbal control module can decide whether the current antenna angle and antenna direction need to be adjusted based on the built-in signal strength and quality algorithm, and automatically adjust them if necessary. Specifically, the gimbal control module can perform deep machine learning based on multiple signal strength and quality sets collected over a long period of time, called feedback data, to fit a function curve that reflects the relationship between signal strength and quality. Specifically, multiple groups of data are first collected. Data collection mainly includes initialization data and data collected and returned under different circumstances. When there is only one outdoor communication device, the initialization data is used as the data set for deep learning. As the number of outdoor communication devices increases, the data returned to the background will gradually increase. The initial data is combined with the data returned by multiple outdoor communication devices as its secondary data set, and then deep machine learning is performed again, thereby iterating again to form a new function curve, which is then upgraded to the outdoor communication device through OTA. The function curve can predict whether the antenna angle needs to be adjusted based on the current signal strength and quality. When the outdoor OUD is turned on, the signal detection module can immediately obtain the signal strength and signal quality corresponding to the adjustable antenna at the current moment, obtain the current signal strength and current signal quality, and input the current signal strength and current signal quality into the function curve for judgment to obtain a judgment result. The return result will obtain a threshold, that is, the offset value of the offset function curve. Then, the judgment result is compared with a preset threshold, wherein the preset threshold is set based on experience and the results obtained in laboratory tests. When the judgment result is greater than the preset threshold, it is determined that the current antenna angle and the current antenna direction are appropriate and no adjustment is required. When the judgment result is less than the preset threshold, it is determined that the current antenna angle and the antenna direction are not optimal and need to be adjusted. When it is determined that adjustment is required, the pan-tilt control module can determine the optimal signal angle and the optimal signal direction, and adjust the antenna angle and antenna direction of the adjustable antenna according to the optimal signal angle and the optimal signal direction. That is, the pan-tilt control module can send a control signal to the signal detection module to perform steps S21 to S24 according to the same embodiment as above.

[0034] When the antenna needs adjustment, the gimbal control module automatically controls the motor on the gimbal to precisely control the antenna's direction and angle of movement. Specifically, the target position and attitude of the antenna are determined based on the optimal signal angle and direction. The motion control algorithm calculates the required motor rotation angle and path, reducing manual intervention and improving efficiency. Furthermore, the adjustable antenna incorporates integrated sensors, such as position and attitude sensors, to directly acquire the antenna's absolute position or relative displacement, as well as its attitude angles (pitch, yaw, and roll), to determine whether the antenna maintains the optimal signal angle and direction during adjustment. In addition to automatic control, manual control is also available, facilitating remote and timely adjustments.

[0035] Through the above optional implementation method, the direction and angle of movement are precisely controlled by the motor, and the position information is fed back by the integrated sensor to ensure the precise positioning of the equipment and the control of the equipment posture. In terms of control method, both manual and automatic modes are flexibly supported. The manual mode facilitates manual remote control and timely adjustment, while the automatic mode relies on preset programs to achieve high-precision and stable automated operation, which can avoid manual climbing of ladders or poles to adjust the ODU signal.

[0036] In an optional embodiment, the outdoor communication equipment adjustment system further includes a signal data storage and display module, and the method further includes: After determining to adjust the antenna angle and the antenna direction, the signal detection module obtains the adjusted new signal data, and transmits the new signal data to the signal data storage and display module through the communication module; The signal data storage and display module stores and visually displays the new signal data.

[0037] In some embodiments, the outdoor communication equipment adjustment system also includes a signal data storage and display module. When the current angle and current direction of the adjustable antenna are adjusted, the signal detection module can detect the signal data corresponding to the new antenna angle and the new antenna direction, which is called new signal data, and also includes signal strength and signal quality. The new signal data is fed back to the signal data storage and display module through the communication module, so that the signal data storage and display module saves and visualizes the new signal data, such as a cloud platform or APP display. In other embodiments, the signal detection module can also transmit the signal data to the IDU and the background server. The background server can store and visualize the received new signal data through the signal data storage and display module.

[0038] In the above embodiments, the description of each embodiment has its own focus. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.
