[0074] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0075] The present invention provides a signal source positioning method, device, electronic device, and computer-readable storage medium. The signal source positioning device can be integrated into an electronic device, which can be a server or a terminal.

[0076] Among them, the server can be an independent physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, network acceleration services (Content Delivery Network, CDN), as well as big data and artificial intelligence platforms.

[0077] The terminal may be a smartphone, tablet computer, laptop computer, desktop computer, smart speaker, smart watch, etc., but is not limited thereto. The terminal and the server may be connected directly or indirectly via wired or wireless communication, and this application does not impose any restrictions thereon.

[0078] In addition, the term "a plurality of" in the embodiments of the present application refers to two or more than two. The terms "first" and "second" in the embodiments of the present application are used to distinguish descriptions and should not be understood to imply relative importance.

[0079] It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments.

[0080] Please refer to Figure 1, which is a flow chart of a signal source localization method provided by an embodiment of the present application. The signal source localization method may include:

[0081] S101: Acquire signal strengths of signals received by a signal receiving point under at least two preset phase states, wherein the signals are sent by a signal source to the signal receiving point.

[0082] In this embodiment, the signal source is a signal transmitter, such as a router. The signal receiving point is a signal receiving end that receives the signal transmitted by the signal source. The signal receiving point can be located in a television and includes at least two antennas. The phase state of the signal receiving point is determined based on the relative positions of the at least two antennas. The phase state specifically includes the phase difference between the antennas and the phase adjustment target (or direction).

[0083] Specifically, by adjusting the phase of one of the multiple antennas, the phase state of the signal receiving point can be adjusted, and the adjustment object is the current phase adjustment object of the signal receiving point. When there are multiple (greater than 2) antennas participating in the signal receiving point, the antennas in the signal receiving point are divided into antenna No. 1 and antenna No. 2, and the phase state is determined by the relative position of antenna No. 1 and antenna No. 2. Among them, antenna No. 1 and antenna No. 2 can both include multiple antennas. For example, when the signal receiving point includes two Wi-Fi antennas and one Bluetooth antenna, the antennas are divided according to the antenna type, and it is determined that the two Wi-Fi antennas constitute antenna No. 1 and the Bluetooth antenna is antenna No. 2. When determining the phase state of the signal receiving point, it is determined by the relative position of antenna No. 1 and antenna No. 2. For example, when the phase of antenna No. 1 is 0° and the phase of antenna No. 2 is 40°, the phase state is 0_40°, where 0 indicates that the phase adjustment target is antenna No. 1, and 40° indicates the phase difference between antenna No. 1 and antenna No. 2. When the phase of antenna No. 1 is 40° and the phase of antenna No. 2 is 0°, the phase state is 1_40°, where 1 indicates that the phase change target is antenna No. 2, and 40° indicates the phase difference between antenna No. 1 and antenna No. 2.

[0084] In at least two preset phase states, the signal strength of the signal received by the signal receiving point is obtained, and the signal strength can be represented by RSSI (Received Signal Strength Indication). In each phase state, the signal strength of the signal received by the signal receiving point may be different.

[0085] Specifically, when acquiring signal strengths corresponding to at least two phase states, this embodiment only changes the phase state of the signal receiving point, without changing the position or orientation of the signal source. For example, by fixing a router in a certain location and adjusting the phase state of the signal receiving point on a television, the signal strengths of the signals received by the receiving point can be obtained under different phase states.

[0086] S102: Perform data processing on the signal strength to obtain target signal characteristic values ​​corresponding to at least two phase states.

[0087] In this embodiment, when the signal strength at the signal receiving point is obtained for each phase state, data processing is performed on the signal strength to obtain target signal characteristic values ​​corresponding to at least two phase states. The target signal characteristic values ​​are characteristic values ​​obtained after the data processing of each signal strength. For example, difference processing is performed on the obtained signal strengths, and the difference between the signal strengths in different phase states is calculated. The target signal characteristic value corresponding to each phase state is then determined from the calculated differences in the order in which the calculations are performed.

[0088] S103: Determine the target direction corresponding to the target signal characteristic value according to the mapping relationship between the direction and the signal characteristic value in the phase state.

[0089] In this embodiment, the mapping relationship refers to the relationship between the azimuth and the signal characteristic value, and different phase states correspond to different mapping relationships. The mapping relationship can be obtained by a mapping curve composed of the azimuth and the signal characteristic value, or it can be determined by a table constructed by the azimuth and the signal characteristic value. According to the different mapping relationships between the azimuth and the signal characteristic value in different phase states, the target azimuth corresponding to the target signal characteristic value can be determined. Specifically, although the mapping relationships between the azimuth and the signal characteristic value corresponding to each phase state are different, different phase states correspond to the same standard azimuth, and the standard azimuth is the azimuth selected from the preset azimuth. Therefore, by obtaining the signal characteristic values ​​of different mapping relationships under the same standard azimuth, multiple standard signal characteristic values ​​corresponding to multiple standard azimuths can be obtained; then the target signal characteristic value is compared with the standard signal characteristic value of each standard azimuth one by one to obtain the matching degree between the target signal characteristic value and each standard azimuth, and the standard azimuth with the highest matching degree is determined as the target azimuth corresponding to the target signal characteristic value.

[0090] S104: Position the angle of the signal source relative to the signal receiving point based on the target orientation.

[0091] In this embodiment, the target orientation is the relative angle between the signal source and the signal receiving point. Therefore, once the target orientation is obtained, the target orientation can be used to locate the angle of the signal source relative to the signal receiving point, or to adjust the beam direction of the signal receiving point to the target orientation. As shown in Figure 2, which shows the orientation of a router and a TV, when the target orientation is 45°, the router is placed at a 45° angle relative to the TV.

[0092] This embodiment obtains the signal strength of the signal received by the signal receiving point under at least two preset phase states, so that the adapted target direction can be determined by the signal strength corresponding to different phase states; then, the signal strength is processed to obtain the target signal characteristic values ​​corresponding to at least two phase states, eliminating the data influence caused by the distance of the signal source, etc., so that the characteristic values ​​obtained by calculation can accurately determine the direction; then, according to the mapping relationship between the direction and the signal characteristic value under the phase state, the target direction corresponding to the target signal characteristic value is determined; based on the target direction, the angle of the signal source relative to the signal receiving point is positioned, thereby achieving accurate determination of the relative direction of the signal source and the signal receiving point, so that when the signal source is in the determined target direction, the signal receiving point has better signal access capability, more concentrated energy, and can avoid signal interference from other directions.

[0093] In some embodiments of the present application, the above-mentioned phase state corresponds to a mapping relationship between an orientation and a signal characteristic value;

[0094] Determining the target direction corresponding to the target signal characteristic value according to the mapping relationship between the direction and the signal characteristic value in the phase state includes:

[0095] Determining, according to a plurality of mapping relationships corresponding to the plurality of phase states, a standard signal characteristic value corresponding to a preset standard orientation in the plurality of mapping relationships;

[0096] The standard orientation is screened based on the standard signal characteristic value and the target signal characteristic value to obtain the target orientation corresponding to the target signal characteristic value.

[0097] In this embodiment, one phase state corresponds to a mapping relationship between an orientation and a signal characteristic value, and multiple phase states correspond to multiple mapping relationships. For example, the mapping relationship corresponding to phase state 1 is A, and the mapping relationship corresponding to phase state 2 is B. The standard orientations of each phase state are the same. For example, for phase state 1 and phase state 2, the corresponding standard orientations include 1°, 7°, 13°, 19°...355°, etc. Based on the multiple mapping relationships corresponding to the multiple phase states, the standard signal characteristic value corresponding to each standard orientation in the multiple mapping relationships is determined. In different phase states, the standard signal characteristic value corresponding to the same standard orientation may be different. Based on the standard signal characteristic value and the target signal characteristic value, the standard orientation is screened to obtain the target orientation corresponding to the target signal characteristic value.

[0098] This embodiment determines the standard signal characteristic value corresponding to the standard orientation in each mapping relationship through multiple mapping relationships corresponding to multiple phase states, so that the target orientation corresponding to the target signal characteristic value can be accurately determined through the standard signal characteristic value, thereby achieving accurate and rapid positioning of the target orientation.

[0099] In some embodiments of the present application, the screening of the standard orientation based on the standard signal characteristic value and the target signal characteristic value to obtain the target orientation corresponding to the target signal characteristic value includes:

[0100] Classifying the standard signal characteristic values ​​according to the standard orientation to obtain a standard characteristic group, wherein the standard characteristic group includes standard signal characteristic values ​​corresponding to the same standard orientation under different mapping relationships;

[0101] comparing the target signal characteristic value with the standard signal characteristic values ​​in the standard characteristic group;

[0102] The standard orientations are screened according to the comparison results, and the standard orientation corresponding to the standard feature group with the highest consistency with the target signal feature value is determined as the target orientation.

[0103] In this embodiment, since multiple phase states correspond to multiple mapping relationships, a standard orientation can obtain multiple standard signal characteristic values ​​under multiple mapping relationships. There are also multiple preset standard orientations. Therefore, the standard signal characteristic values ​​are classified according to the standard orientation to obtain a standard characteristic group. The standard signal characteristic values ​​in a standard characteristic group are the standard signal characteristic values ​​corresponding to the same standard orientation under the mapping relationships corresponding to different phase states. The standard signal characteristic value in each phase state is the gain value of each orientation in its corresponding phase state. For example, in mapping relationships A, B, and C, the standard signal characteristic values ​​corresponding to the standard orientation 1° are 1db, 5db, and 10db respectively; in mapping relationships A, B, and C, the standard signal characteristic values ​​corresponding to the standard orientation 2° are 3db, 4db, and 20db respectively. The standard characteristic group corresponding to the standard orientation 1° includes 1db, 5db, and 10db, and the standard characteristic group corresponding to the standard orientation 2° includes 3db, 4db, and 20db.

[0104] Among them, the target signal characteristic value is the characteristic value obtained under each phase state, so the number of target signal characteristic values ​​is the same as the number of standard signal characteristic values. The target signal characteristic value and the standard signal characteristic value in the standard characteristic group are compared one by one according to the phase state. Specifically, the target signal characteristic value is compared with the standard signal characteristic value of the same phase state in the standard characteristic group, and the standard orientation is screened according to the comparison result. If the target signal characteristic value has the highest degree of consistency with all the standard signal characteristic values ​​in a standard characteristic group, or has the largest number of standard signal characteristic values ​​with the highest degree of consistency in the standard characteristic group, then the standard orientation corresponding to the standard characteristic group is determined to be the target orientation. When the target signal characteristic value has the highest degree of consistency with all the standard signal characteristic values ​​in a standard characteristic group, or has the largest number of standard signal characteristic values ​​with the highest degree of consistency in the standard characteristic group, then it is determined that the target signal characteristic value has the highest degree of match with the standard orientation corresponding to the standard signal characteristic value with the highest degree of consistency.

[0105] For example, the target signal characteristic value includes a target signal characteristic value of 10db corresponding to phase state 1 and a target signal characteristic value of 20db corresponding to phase state 2; the standard feature group corresponding to the standard azimuth 30° includes a standard signal characteristic value of 9db corresponding to phase state 1 and a standard signal characteristic value of 18db corresponding to phase state 2; the standard feature group corresponding to the standard azimuth 50° includes a standard signal characteristic value of 5db corresponding to phase state 1 and a standard signal characteristic value of 12db corresponding to phase state 2. By comparing the target signal characteristic value under phase state 1 with the phase state 1 in each standard feature group, and comparing the target signal characteristic value under phase state 2 with the phase state 2 in each standard feature group, it can be seen that the standard signal characteristic value in the standard feature group corresponding to the standard azimuth 30° has the highest consistency with the target signal characteristic value. Therefore, the standard azimuth 30° is selected as the target azimuth.

[0106] This embodiment classifies the standard signal characteristic values ​​according to the standard orientation to obtain a standard characteristic group, and then compares the target signal characteristic value with the standard signal characteristic value in the standard characteristic group, and filters the standard orientation according to the comparison result to obtain the target orientation, thereby achieving accurate determination of the target orientation, so that the signal receiving point can have better signal access capability under the determined target orientation.

[0107] In some embodiments of the present application, the signal receiving point includes at least two antennas, and before obtaining the signal strength of the signal received by the signal receiving point in the at least two preset phase states, the method further includes:

[0108] Adjusting the length of the radio frequency line segment connected to any one of the antennas at the signal receiving point;

[0109] The phase state of the signal receiving point is determined according to the length.

[0110] In this embodiment, the signal receiving point includes at least two antennas, and the distance between the antennas is approximately 1 wavelength. The phase state is determined by the at least two antennas at the signal receiving point, and the phase state of the signal receiving point can be changed by adjusting the phase of one antenna. The adjustment of the antenna phase in this embodiment can be specifically achieved by adjusting the length of the RF segment connected to the antenna. As shown in Figure 3, Figure 3 is a RF network diagram including two antennas. Among them, RF is radio frequency, SPDT is single-pole double-throw switch, PD is photoelectric converter, SP4T is radio frequency switch, DPDT double-pole double-throw switch, ANT1 and ANT0 represent antenna 1 and antenna 0 respectively. RF segments of different lengths are selected by the RF switch to make a predetermined fixed phase shift degree (as shown in Figure 3, by selecting 0°, 40°, 90° and 180° through two RF switches SP4T, the switching of the fixed phase shift degree can be achieved, and the fixed phase shift degree is determined by the length of the connected RF segment). Therefore, by selecting different lengths of the RF line segment connected to one of the antennas, different fixed phase shift degrees corresponding to different lengths are determined, and then the relative distance between the two antennas is changed, ultimately achieving adjustment of the phase state of the signal receiving point.

[0111] This embodiment determines the phase state of the signal receiving point by adjusting the length of the RF line segment connected to any antenna in the signal receiving point, thereby achieving rapid adjustment of the phase state of the signal receiving point, so that the optimal orientation of the signal source and the signal receiving point can be accurately determined through the target signal characteristic values ​​under different phase states.

[0112] In some embodiments of the present application, the signal receiving point further includes a Bluetooth antenna, and determining the phase state of the signal receiving point according to the length includes:

[0113] Constructing a multi-element antenna array based on the Bluetooth antenna and at least two of the antennas;

[0114] Based on the multi-element antenna array and the length, a phase state of the signal receiving point is determined.

[0115] In this embodiment, the signal receiving point may also include a Bluetooth antenna. The Bluetooth antenna and at least two antennas can form a multi-element antenna array. The phase state of the signal receiving point can be determined by the multi-element antenna array and the length of the radio frequency segment connected to one of the antennas. As shown in Figure 4, Figure 4 is a diagram of a radio frequency network including a Bluetooth antenna. Figure 4 includes two Wi-Fi antennas (ANT_W0 and ANT_W1) and a Bluetooth antenna (ANT_BT). The Bluetooth antenna ANT_BT operates between the Bluetooth and positioning radio frequency networks via a single-pole double-throw switch (SPDT), wherein the positioning radio frequency network is the radio frequency network where the two Wi-Fi antennas are located. The Bluetooth antenna has a high degree of isolation from the Wi-Fi antenna, and the connection between the Bluetooth antenna and the positioning radio frequency network can be switched via the single-pole double-throw switch. When the Bluetooth antenna and the two Wi-Fi antennas are in a sideways state, a three-element antenna array is formed. At this time, the phase of the signal receiving point is an arithmetic progression, and its corresponding horizontal directional pattern is an end-fire state. In addition, non-Bluetooth type antennas can also be added to the signal receiving point. This embodiment does not limit the type of added antennas.

[0116] This embodiment adds a Bluetooth antenna at the signal receiving point, which can make the signal characteristic value determined by the phase state formed by the Bluetooth antenna and the original antenna more significant, and forms a multi-element antenna array by the Bluetooth antenna and the original antenna at the signal receiving point, which can make the phase state determined by the multi-element antenna array more accurately obtain the optimal radiation direction of the antenna, further improving the azimuth positioning accuracy.

[0117] In some embodiments of the present application, before determining the target direction corresponding to the target signal characteristic value according to the mapping relationship between the direction and the signal characteristic value in the phase state, the method further includes:

[0118] In the phase state, measuring the standard signal strength of the signal receiving point at a plurality of preset standard directions;

[0119] A mapping relationship between the azimuth corresponding to the phase state and the signal characteristic value is determined according to the standard azimuth and the standard signal strength.

[0120] In this embodiment, there are multiple standard orientations and phase states. In a preset phase state, the standard signal strength of the signal receiving point in multiple preset standard orientations is measured. Among them, one phase state can measure the standard signal strength of multiple different standard orientations. For example, when the signal source is a router and the signal receiving point is set in the TV, by fixing the position of the TV, the router is placed around the TV for a week, and the RSSI value corresponding to each observation point in different phase states is measured, that is, the standard signal strength of each observation point corresponding to the different phase states is obtained, and the standard orientation corresponding to each observation point is different. In this way, the standard signal strength of the router relative to the TV in different standard orientations under the same phase state can be obtained.

[0121] Afterwards, the standard signal strength is processed to convert it into a standard signal characteristic value. This data processing is identical to the signal strength data processing described above. Each phase state corresponds to the same standard azimuth. The same standard azimuth may correspond to different standard signal characteristic values ​​in different phase states. Therefore, the standard azimuth and standard signal characteristic values ​​corresponding to each phase state can be used to determine the mapping relationship between the azimuth and signal characteristic values ​​corresponding to each phase state.

[0122] This embodiment measures the standard signal strength of the signal receiving point at multiple standard orientations in a phase state in advance, and then determines the mapping relationship between the orientation corresponding to the phase state and the signal characteristic value based on the standard orientation and the standard signal strength. This allows the target orientation of the signal source and the signal receiving point to be accurately and quickly determined through the mapping relationship, and makes the target orientation more closely fit the orientation corresponding to the high radiation intensity.

[0123] In some embodiments of the present application, determining the mapping relationship between the azimuth corresponding to the phase state and the signal characteristic value according to the standard azimuth and the standard signal strength includes:

[0124] Determining, according to the standard azimuth and the standard signal strength, at least two radiation ranges corresponding to the signal receiving point in at least two phase states, where one phase state corresponds to one radiation range;

[0125] Determining, from the standard signal strengths of at least two of the radiation ranges, the standard signal characteristic values ​​corresponding to the standard orientation in each of the phase states;

[0126] The standard azimuth and the standard signal characteristic value are mapped to obtain a mapping relationship between the azimuth and the signal characteristic value corresponding to each phase state.

[0127] In this embodiment, when determining the mapping relationship between the azimuth and signal characteristic value corresponding to the phase state based on the standard azimuth and standard signal strength, at least two radiation ranges of the signal receiving point in at least two phase states can also be determined based on the standard azimuth and standard signal strength. Different phase states correspond to different radiation ranges, and one phase state corresponds to one radiation range. As shown in Figure 5, Figure 5 is the radiation pattern of the signal receiving point in different phase states. The radiation pattern is an omnidirectional radiation pattern, and the radiation range corresponding to each phase state can be represented by the radiation pattern corresponding to each phase state. Among them, the outer circle of each radiation pattern in Figure 5 represents the azimuth, and the inner circle represents the gain value. The gain value is the standard signal strength in this embodiment. In the figure, the standard signal strength increases from -28 to -1. 0_0° indicates that the phases of the antennas at the signal receiving point are the same, and the phase difference is 0°; 0_40° indicates that the phase of antenna 1 at the signal receiving point is 0°, the phase of antenna 2 is 40°, and the phase difference between antenna 1 and antenna 2 is 40°; 1_180° indicates that the phases of the antennas at the signal receiving point are opposite, and antenna 1 and antenna 2 are opposite. 2, the phase difference between antenna 1 and antenna 2 is 180°; 1_40° indicates that the phase of antenna 1 at the signal receiving point is 40°, the phase of antenna 2 is 0°, and the phase difference between antenna 1 and antenna 2 is 40°; 0_90° indicates that the phase of antenna 1 at the signal receiving point is 0°, the phase of antenna 2 is 90°, and the phase difference between antenna 1 and antenna 2 is 90°; 1_90° indicates that the phase of antenna 1 at the signal receiving point is 90°, the phase of antenna 2 is 0°, and the phase difference between antenna 1 and antenna 2 is 90°. In one embodiment, a mapping function can also be determined based on the standard azimuth and standard signal strength corresponding to each phase state, and a mapping relationship corresponding to each phase state is obtained based on the mapping function.

[0128] Furthermore, when the signal receiving point also includes a Bluetooth antenna, the phase state of the signal receiving point also changes with the state of the Bluetooth antenna and the other two antennas. This allows us to derive the radiation range corresponding to the signal receiving point when the Bluetooth antenna and the other two antennas form a three-element antenna array. Figure 6 shows the radiation pattern of a three-element antenna array consisting of a Bluetooth antenna and two Wi-Fi antennas in end-fire mode.

[0129] After determining the radiation range of the signal receiving point in different phase states, the standard signal characteristic value corresponding to the standard azimuth in each phase state is determined from the standard signal strengths of at least two radiation ranges. For example, according to a preset calculation sequence, the standard signal strengths of different radiation ranges under the same standard azimuth are calculated to obtain the standard signal characteristic value corresponding to each standard azimuth. The standard azimuth and the standard signal characteristic value are mapped to obtain a mapping relationship between the azimuth and the signal characteristic value corresponding to each phase state. This mapping relationship can be represented by a mapping curve between the azimuth and the signal characteristic value.

[0130] As shown in Figure 7, Figure 7 is a mapping curve of azimuth and signal characteristic values ​​corresponding to different phase states, and different mapping curves correspond to mapping relationships of different phase states. Among them, the horizontal axis represents the azimuth, and the vertical axis represents the signal characteristic value. The signal characteristic value can be obtained by calculating the difference in signal strength corresponding to the same azimuth in at least two radiation ranges. In this embodiment, the mapping curve of the azimuth and signal characteristic value of each phase state can be obtained by performing difference calculation on the radiation pattern corresponding to each phase state. The difference calculation can be specifically performed by subtracting the gain values ​​under the same azimuth in each radiation pattern, that is, obtaining the signal characteristic value corresponding to each orientation. For example, the radiation pattern corresponding to each phase state in Figure 5 is subjected to difference calculation, and the three mapping curves in Figure 7 are obtained. Among them, the blue curve in Figure 7 is the mapping curve obtained by subtracting the radiation pattern a from the radiation pattern b in Figure 5, the red curve is the mapping curve obtained by subtracting the radiation pattern c from the radiation pattern f in Figure 5, and the gray curve is the mapping curve obtained by subtracting the radiation pattern d from the radiation pattern e in Figure 5.

[0131] [Corrected 18.03.2025 according to Rule 91] Furthermore, when the signal receiving point also includes a Bluetooth antenna, the radiation range of the signal receiving point in different phase states, based on the radiation range and azimuth, determines the mapping curve of the azimuth and signal characteristic value corresponding to each phase state when the Bluetooth antenna is involved. As shown in Figure 8, Figure 8 is a mapping curve of the azimuth and signal characteristic value corresponding to different phase states of the signal receiving point including the Bluetooth antenna. Similarly, each mapping curve in Figure 8 can be obtained by subtracting the radiation patterns under each phase state measured by the Bluetooth antenna and the two Wi-Fi antennas. From the comparison of Figures 7 and 8, it can be seen that after adding the Bluetooth antenna to the signal receiving point, its azimuth asymmetry is better. By adding the three-antenna signal receiving point after the Bluetooth antenna, the azimuth can be better distinguished, thereby improving the accuracy of the azimuth positioning of the signal source and the signal receiving point.

[0132] This embodiment determines the radiation range through the standard azimuth and standard signal strength, so that the optimal radiation direction corresponding to the signal receiving point can be accurately determined through the radiation range. Then, the mapping relationship between the azimuth and the signal characteristic value is determined through the radiation range, thereby realizing the precise conversion of the radiation range and the mapping relationship, so that the target signal characteristic value obtained can be used to accurately obtain the target azimuth corresponding to the target signal characteristic value based on the mapping relationship, thereby realizing the precise positioning of the optimal azimuth, improving the signal access capability of the signal receiving point, and avoiding signal divergence.
