[0079] The term "and / or" in the embodiments of the present application describes the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B can represent the following three cases: A exists alone, A and B exist together, and B exists alone. The character " / " generally represents an "or" relationship between the associated objects before and after it.

[0080] The term "multiple" in the embodiments of the present application means two or more, and other quantifiers are similar.

[0081] The technical solutions in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0082] In the embodiments of the present application, a bearing angle auxiliary calibration method for a sensing base station is provided. The bearing angle calibration of the sensing base station is completed by installing an auxiliary calibration device on other base stations near the sensing base station, so that the sensing base station can be dynamically calibrated without manual tower operation, and the use of devices such as unmanned aerial vehicles that may be limited is avoided, the labor cost is reduced, and the calibration efficiency is improved.

[0083] Referring to Figure 1 , Figure 1 is a flowchart of the bearing angle calibration method provided by the embodiments of the present application, as shown in Figure 1 , comprising the following steps:

[0084] Step 101: Obtain a first bearing angle corresponding to a line connecting a sensing base station and an auxiliary calibration device, wherein the auxiliary calibration device is arranged in an auxiliary base station, and the auxiliary base station is located on a direct view diameter within a sensing range of the sensing base station.

[0085] In combination with Figure 2 , the sensing base station A1 is deployed at site A, and another site B exists on the direct view diameter within the sensing range of the sensing base station A1, which can be used as an auxiliary base station. An auxiliary calibration device B1 is installed on the site B, which can be an auxiliary signal transceiver device, for example. Since the latitude and longitude positions of the sensing base station A1 and the auxiliary calibration device B1 can be measured, the bearing angle of the line connecting the sensing base station A1 and the auxiliary calibration device B1, i.e., the first bearing angle P1, can also be calculated. In the embodiments of the present application, it is not limited how to calculate the first bearing angle from the latitude and longitude positions of the sensing base station A1 and the auxiliary calibration device B1.

[0086] Step 102: Obtain a second bearing angle corresponding to the line connecting the sensing base station and the auxiliary calibration device in a sensing manner.

[0087] In an embodiment of the present application, the sensing base station may obtain the second azimuth angle in at least the following manner.

[0088] In the first method, the sensing base station transmits a specific calibration signal, which is received by the auxiliary calibration device.

[0089] The sensing base station transmits calibration signals with different beam orientations to the sensing range in a time-division manner and receives first information, wherein the first information is used to indicate the signal strength of the calibration signal received by the auxiliary calibration device and the beam orientation information of the calibration signal, or the first information is used to indicate the signal strength of the target calibration signal and the beam orientation information of the target calibration signal, wherein the target calibration signal is the calibration signal with the strongest signal strength among the calibration signals received by the auxiliary calibration device. The sensing base station then calculates the second azimuth angle based on the first information.

[0090] The sensing base station may receive the first information from the auxiliary calibration device or from a server, where the server obtains the first information from the auxiliary calibration device. If the first information indicates the signal strength of the calibration signal received by the auxiliary calibration device and the beam pointing information of the calibration signal, the sensing base station may determine the calibration signal with the strongest signal strength and the corresponding beam pointing information among the calibration signals received by the auxiliary calibration device.

[0091] For example, after the perception base station starts the calibration process, it can send narrow beams according to certain rules and inform the auxiliary calibration device to maintain synchronization with the perception base station through the network management system. Assume that the beam numbers sent are c1, c2, c3..., and at certain time intervals, the perception base station sends a beam (calibration signal), and the auxiliary calibration device can record the signal strength of the received beam and the beam pointing information. When the direction of the beam is far away from the auxiliary calibration device, the auxiliary calibration device may not be able to receive the sent signal. At this time, the auxiliary calibration device can be recorded as empty (or other marks). After all beams are sent, the auxiliary calibration device feeds back the first information to the perception base station. Then, the perception base station can calculate the second azimuth information based on this first information. Here, it is assumed that the auxiliary calibration device is an omnidirectional antenna and has no directionality itself, so as to ensure that the signal strength received by the perception base station is only related to the direction of the received beam.

[0092] In the second method, the sensing base station transmits a specific calibration signal, which is received by the auxiliary calibration device.

[0093] The perception base station time-divisionally transmits calibration signals with different beam orientations within a perception range, and receives a second azimuth angle sent by a server, wherein the server is configured to determine the second azimuth angle according to first information sent by the auxiliary calibration device, and the first information is used to indicate the signal strength of the calibration signal received by the auxiliary calibration device and the beam orientation information of the calibration signal, or the first information is used to indicate the signal strength of a target calibration signal and the beam orientation information of the target calibration signal, wherein the target calibration signal is the calibration signal with the strongest signal strength received by the auxiliary calibration device.

[0094] That is, in this way, the server calculates the second azimuth angle and sends the second azimuth angle to the perception base station.

[0095] For example, after the perception base station starts the calibration process, it can transmit narrow beams according to certain rules and inform the auxiliary calibration device to keep synchronization with the perception base station through a network management system. Assuming that the transmitted beam numbers are c1, c2, c3,..., every certain time interval, the perception base station transmits a beam (calibration signal), and the auxiliary calibration device can record the received signal strength and beam orientation information of the received beam. When the orientation of the beam is far away from the auxiliary calibration device, the auxiliary calibration device may not be able to receive the transmitted signal, in which case the auxiliary calibration device can record it as empty (or other marks). After all the beams are transmitted, the auxiliary calibration device feeds back the first information to the server.

[0096] If the first information is used to indicate the signal strength of the calibration signal received by the auxiliary calibration device and the beam orientation information of the calibration signal, the server can determine the calibration signal with the strongest signal strength received by the auxiliary calibration device and the corresponding beam orientation information therefrom.

[0097] In the third way, the auxiliary calibration device transmits a specific calibration signal, and the perception base station receives it.

[0098] The perception base station time-divisionally receives the calibration signal sent by the auxiliary calibration device through beams with different orientations, determines the beam orientation information of a target beam, wherein the target beam makes the received calibration signal have the strongest strength, and calculates the second azimuth angle according to the beam orientation information of the target beam.

[0099] For example, after the perception base station starts the calibration process, it starts to receive the specific calibration signal transmitted by the auxiliary calibration device through different beam directions in time division. For each scanning beam direction, the perception base station records the received calibration signal strength, and when the calibration signal cannot be received, it can be recorded as empty or other marks. After the scanning is completed, the perception base station filters out the beam with the strongest received signal strength, and calculates the second azimuth angle information according to the beam direction information of the beam. Here, it is assumed that the auxiliary calibration device is an omnidirectional antenna and has no directionality itself, so as to ensure that the signal strength received by the perception base station is only related to the direction of the receiving beam.

[0100] In the embodiment of the present application, since the working frequency band of the perception base station is a mobile communication frequency band, there may be strong co-frequency signals in the existing network, therefore, the perception base station needs to transmit a signal with certain characteristics, so that the auxiliary calibration device can detect and accurately identify this signal. Therefore, the calibration signal is encoded by a preset encoding mode, or the calibration signal has a preset time domain feature (such as a special pulse signal). The encoding mode is not limited here, as long as the perception base station and the auxiliary calibration device can identify the signal as a calibration signal.

[0101] Step 103, calibrating the second azimuth angle according to the first azimuth angle.

[0102] Here, the second azimuth angle can be adjusted by the first azimuth angle to obtain the calibrated azimuth angle of the perception base station.

[0103] In the embodiment of the present application, the calibration of the azimuth angle of the perception base station can be completed by the auxiliary calibration device arranged in the auxiliary base station, without introducing auxiliary calibration equipment with limited application, so as to improve the calibration efficiency of the azimuth angle of the perception base station. At the same time, by using this method, the background can trigger the calibration process at any time according to the setting, without manual on-site operation, and can be calibrated periodically or at any time and dynamically according to the needs, avoiding manual cost and being more efficient.

[0104] Referring to Figure 3 , Figure 3 is a flowchart of the azimuth angle calibration method provided by the embodiment of the present application, applied to an auxiliary calibration device arranged in an auxiliary base station, as shown in Figure 3 , comprising the following steps:

[0105] Step 301, receiving a calibration signal of different beam pointing sent by the sensing base station in time division, and obtaining first information, wherein the first information is used to indicate the signal strength of the calibration signal received by the auxiliary calibration device and the beam pointing information of the calibration signal, or the first information is used to indicate the signal strength of the target calibration signal and the beam pointing information of the target calibration signal, the target calibration signal is the calibration signal with the strongest signal strength received by the auxiliary calibration device; the first information is used for the sensing base station to obtain a second azimuth angle corresponding to the connection between the sensing base station and the auxiliary calibration device in a sensing manner.

[0106] For example, after the sensing base station starts the calibration process, it can send narrow beams according to certain rules and inform the auxiliary calibration device to keep synchronization with the sensing base station through the network management system. Assuming that the beam numbers sent are c1, c2, c3,..., every certain time interval, the sensing base station sends a beam (calibration signal), and the auxiliary calibration device can record the signal strength and beam pointing information of the received beam. When the pointing of the beam is far away from the auxiliary calibration device, the auxiliary calibration device may not be able to receive the signal, in which case the auxiliary calibration device can record it as empty (or other marks). After all the beams are sent, the auxiliary calibration device feeds back the first information to the sensing base station. Then, the sensing base station can calculate the second azimuth angle information according to the first information. Here, it is assumed that the auxiliary calibration device is an omnidirectional antenna and has no directivity to ensure that the signal strength received by the sensing base station is only related to the pointing of the received beam.

[0107] Alternatively, the auxiliary calibration device sends a calibration signal to the sensing base station, which is received by the sensing base station in time division through different pointing beams, and the beam pointing information of the target beam is determined, and the second azimuth angle is calculated according to the beam pointing information of the target beam, wherein the target beam makes the received calibration signal the strongest.

[0108] For example, after the sensing base station starts the calibration process, the auxiliary calibration device can send narrow beams according to certain rules. After the sensing base station starts the calibration process, it starts to receive specific calibration signals transmitted by the auxiliary calibration device in time division through different pointing beams. For each scanning beam pointing, the sensing base station records the received calibration signal strength, and similarly, it can record it as empty or other marks when it cannot receive the calibration signal. After scanning is completed, the sensing base station filters out the beam with the strongest signal strength, and calculates the second azimuth angle information according to the beam pointing information of the beam. Here, it is assumed that the auxiliary calibration device is an omnidirectional antenna and has no directivity to ensure that the signal strength received by the sensing base station is only related to the pointing of the received beam.

[0109] In the embodiment of the present application, since the working frequency band of the sensing base station is a mobile communication frequency band, there can be a strong co-frequency signal in the existing network, and therefore the sensing base station needs to transmit a signal with certain characteristics so that the auxiliary calibration device can detect and accurately identify the signal. Therefore, the calibration signal is encoded by a preset encoding mode, or the calibration signal has a preset time domain characteristic (such as a special pulse signal). The encoding mode is not limited here, as long as the sensing base station and the auxiliary calibration device can identify the signal as a calibration signal.

[0110] In the embodiment of the present application, the calibration of the azimuth angle of the sensing base station can be completed by the auxiliary calibration device arranged in the auxiliary base station, without introducing auxiliary calibration equipment with limited application, thereby improving the calibration efficiency of the azimuth angle of the sensing base station. At the same time, by using this method, the background can trigger the calibration process at any time, without manual on-site operation, and the calibration can be performed periodically or at any time as needed, avoiding manual cost and being more efficient.
