[0067] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings. The specific operating methods in the method embodiments can also be applied to the device embodiments, system embodiments, and computer program products.

[0068] In the description of this application, "multiple" is understood as "at least two". "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. A connected to B can represent: A and B directly connected, or A and B connected through C. Furthermore, in the description of this application, terms such as "first" and "second" are used only for descriptive purposes and should not be construed as indicating or implying relative importance or order.

[0069] The design concept of the embodiments of this application will be briefly introduced below.

[0070] Currently, for low-frequency signal allocation, especially in a large photovoltaic area, the frequency band is uniformly allocated by the owner after communication and confirmation with various manufacturers. Although existing wireless equipment management methods can avoid interference to some extent, several problems remain. First, the current methods typically involve manual operation when setting the center frequency and bandwidth, which is inefficient and prone to errors. Second, uniformly allocating frequency bands requires communication with the photovoltaic area owners, which is time-consuming and labor-intensive.

[0071] To address the aforementioned technical problems, this application provides a wireless device frequency adjustment method. This method, by automatically adjusting the center frequency and bandwidth, and by scanning and responding to interference sources in real time, can effectively manage wireless devices, avoid mutual interference, and improve the stability and reliability of the system.

[0072] It is worth noting that the technical features included in the embodiments of this application can be used in any combination. Those skilled in the art should understand that, based on actual application situations, the technical solutions obtained by reasonably combining the technical features in the embodiments of this application can also solve the same technical problems or achieve the same technical effects.

[0073] The method provided in the embodiments of this application will be further described in detail below with reference to the accompanying drawings.

[0074] See Figure 1 As shown in the figure, this application embodiment provides a wireless device frequency adjustment method, which is applied to a communicator. First, step 101 involves scanning according to a preset scanning bandwidth to determine whether there is an interference source.

[0075] In this embodiment of the application, preferably, before performing interference source scanning, an initial center frequency and scanning bandwidth are first set for the communicator. The initial center frequency can be set to any frequency in the low-frequency band or the mid-frequency band. The low-frequency band can range from 433MHz to 434MHz, and the mid-frequency band can range from 865MHz to 875MHz or 902MHz to 928MHz. The scanning bandwidth can be set based on actual testing. Tests have shown that when the scanning bandwidth is set to 60kHz or less, the communication itself will be interfered with. For example, if one frequency is 410.00MHz and the other is 410.05MHz, these two frequencies will be interfered with. Therefore, it is preferable to set the scanning bandwidth to be greater than 60kHz, for example, 0.1MHz.

[0076] In addition to the initial center frequency and bandwidth, the scan time and total number of scans also need to be set. It should be noted that the total number of scans equals the preset fixed bandwidth divided by the preset scan bandwidth. For example, if the preset scan bandwidth is 0.1MHz, the total number of scans is 1MHz ÷ 0.1MHz = 10; if the preset scan bandwidth is 0.2MHz, the total number of scans is 1MHz ÷ 0.2MHz = 5. The preset fixed bandwidth is the threshold value for determining that the current center frequency has reached its maximum. The scan time is set according to actual needs; for example, if set to 10 seconds and the number of scans is 10, then 10 scans need to be completed within the 10-second scan time.

[0077] Then, a scan is performed according to a preset scanning bandwidth to determine whether there is an interference source nearby. In one embodiment, the method for scanning for interference sources is data scanning. Specifically, a data scan is performed according to the preset scanning bandwidth. If data is scanned, it indicates that there is a communicator of the same type nearby, and it is determined that there is an interference source; if no data is scanned, it is determined that there is no interference source.

[0078] In one embodiment, the method for scanning for interference sources is signal quality scanning. Specifically, signal quality scanning is performed according to a preset scanning bandwidth. If a signal is detected and its quality is greater than a set standard, for example, if the signal quality is -30 dBm and greater than the set standard of -50 dBm, then an interference source is determined to exist. If a signal is detected and its quality is less than or equal to the set standard, for example, if the signal quality is -50 dBm and equal to the set standard, then an interference source is determined to not exist. If no signal is detected, it is also determined that no interference source exists.

[0079] In one embodiment, the method of scanning interference sources is data scanning and signal quality scanning. By using both data scanning and signal quality scanning to scan interference sources, the detection accuracy of nearby interference sources can be improved.

[0080] In one embodiment, if an interference source is determined to exist, step 102 is executed. In another embodiment, if no interference source is determined to exist, step 103 is executed.

[0081] Further reference Figure 1 Step 102 involves shifting the current center frequency of the communicator to the left or right by a preset scanning bandwidth if an interference source is present, and updating the scan count. In this embodiment, when an interference source is determined to exist near the communicator, the current center frequency of the communicator is shifted to the left or right by a preset scanning bandwidth, and the scan count is updated.

[0082] Taking the first scan as an example, the communicator's current center frequency is the initial center frequency of 433MHz, the scan count is 0, and the scan bandwidth is 0.1MHz. When an interference source is detected near the communicator, the current center frequency is shifted to the right to 433MHz + 0.1MHz = 433.1MHz, and the scan count is incremented by 1. After updating the scan count, it is determined whether the current scan count is greater than or equal to the total scan count. In one implementation, if the current scan count is greater than or equal to the total scan count, the current center frequency is reported as full, and the scan ends. In another implementation, if the current scan count is less than the total scan count, the scan continues.

[0083] Further reference Figure 1Step 103 involves storing the current center frequency and ending the scan if no interference source is detected. In this embodiment, when it is determined that no interference source is present near the communicator, the current center frequency is stored and the scan ends. It is worth noting that when the method provided in this embodiment is applied to a photovoltaic power generation scenario, the communicator is specifically a photovoltaic tracking communicator. The photovoltaic tracking communicator can be used to monitor meteorological information of the photovoltaic power station in real time, such as temperature, humidity, and wind speed, and send control commands to the photovoltaic tracking controller based on the monitored meteorological information. For example, it can send control commands to the photovoltaic tracking controller when extreme weather is detected, ensuring that the photovoltaic tracking controller adjusts the angle in a timely manner to ensure the safety of the photovoltaic modules.

[0084] The above method, through real-time scanning, can respond to changes in interference in real time and adjust the center frequency of wireless devices promptly, improving the real-time performance and accuracy of wireless device management. By setting a smaller scanning bandwidth and a larger number of scans, the utilization rate of spectrum resources can be optimized while ensuring communication, avoiding resource waste and improving resource utilization.

[0085] Furthermore, in this embodiment of the application, the communicator and the controller communicate. When the communicator receives an interrogation signal sent by the controller, it sends a response signal to the controller. The interrogation signal is used to confirm whether the controller and the communicator are at the same center frequency, so as to ensure normal communication between the communicator and the controller.

[0086] See Figure 2 As shown in the figure, this application embodiment provides a wireless device frequency adjustment method, which is applied to a controller. First, step 201 involves scanning the communicator according to a preset scanning bandwidth to determine whether a response signal sent by the communicator is received.

[0087] First, set the controller's initial center frequency, scan bandwidth, scan time, and the number of scans by the communicator. Set the controller's initial center frequency and scan bandwidth to be the same as the communicator's initial center frequency and scan bandwidth. For example, if the communicator's initial center frequency is 433MHz and its scan bandwidth is 0.1MHz, then the controller's initial center frequency should also be set to 433MHz and its scan bandwidth to 0.1MHz.

[0088] In this embodiment, communicator scanning refers to the controller continuously sending a predetermined number of query signals. For example, when performing a communicator scan, the controller continuously sends three query signals to the communicator. The scanning time and the number of communicator scans are set according to actual needs. For instance, if the scanning time is set to 10 seconds and the number of communicator scans is 10, then 10 communicator scans are performed within 10 seconds, with three query signals sent for each scan. The controller performs communicator scanning according to a preset scanning bandwidth and determines whether it receives a response signal from the communicator.

[0089] In one possible implementation, if no acknowledgment signal is received from the communicator, step 203 is executed. In another possible implementation, if an acknowledgment signal is received from the communicator, step 204 is executed.

[0090] Furthermore, Figure 2 Step 202, as shown, involves shifting the controller's current center frequency to the left or right by a preset scanning bandwidth if no response signal is received, and updating the communicator's scan count. In this embodiment, if the controller does not receive a response signal from the communicator, it shifts the controller's current center frequency to the left or right by a preset scanning bandwidth and updates the communicator's scan count. For example, the controller's current center frequency is shifted to the right to 433MHz + 0.1MHz = 433.1MHz, and the communicator's scan count is incremented by 1.

[0091] After updating the communicator scan count, it is also necessary to determine whether the current communicator scan count is greater than or equal to the set scan count. In one possible implementation, if the current communicator scan count is greater than or equal to the set scan count, the communicator scan ends and a message indicating that no communicator exists is displayed. In another possible implementation, if the current communicator scan count is less than the set scan count, the communicator scan continues.

[0092] Furthermore, Figure 2 Step 203, as shown, involves storing the current center frequency and ending the communicator scan if a response signal is received. In this embodiment, if the controller receives a response signal from the communicator, indicating that the controller and the communicator are on the same frequency and can communicate, the current center frequency is stored and the communicator scan ends. It is worth noting that when the method provided in this embodiment is applied to a photovoltaic power generation scenario, the controller is specifically a photovoltaic tracking controller. The photovoltaic tracking controller receives control commands sent by the photovoltaic tracking communicator and adjusts the photovoltaic modules according to the control commands.

[0093] The above method sets the controller's center frequency and scanning bandwidth according to the communicator's center frequency and scanning bandwidth. By scanning the communicator in real time, it achieves automatic adjustment of the center frequency, ensuring the communication connection between the controller and the communicator, improving the compatibility of wireless devices, and can be widely used in the management of various wireless devices.

[0102] Optionally, the device is further configured to: determine whether the current number of communicator scans is greater than or equal to a set number of scans; if the current number of communicator scans is greater than or equal to the set number of scans, then end the communicator scan and indicate that no communicator exists; if the current number of communicator scans is less than the set number of scans, then continue the communicator scan.
