Description

Bluetooth ranging method, electronic equipment and storage medium

Technical Field

The application relates to the field of terminal equipment, in particular to a Bluetooth ranging method, electronic equipment and a storage medium.

Background

Devices with bluetooth functions (e.g., mobile phones) may have different received signal strength values of mobile phones with different hardware configurations or mobile phones under different service data due to different configuration conditions of their own hardware (e.g., antennas) and different current service data (e.g., wi-Fi service data). However, the received signal strength value is typically one of the parameters used to calculate the range in the associated bluetooth ranging method. Thus, the distances calculated when applied to bluetooth ranging are different for mobile phones with different hardware configurations or mobile phones under different service data, so that the mobile phone ranging can obtain inconsistent distance results.

Disclosure of Invention

In view of the foregoing, it is necessary to provide a bluetooth ranging method, an electronic device and a storage medium to solve the technical problem that the bluetooth ranging result is inconsistent.

In a first aspect, an embodiment of the present application provides a bluetooth ranging method, which is applied in a bluetooth device, where the bluetooth device is connected with a device to be measured in bluetooth, and the method includes: when starting Bluetooth ranging, determining a Bluetooth mode of the Bluetooth equipment according to configuration information of an antenna of the Bluetooth equipment; determining the insertion loss value of the Bluetooth equipment according to the Bluetooth mode; receiving a Bluetooth signal sent by the equipment to be measured, and acquiring a transmitting power value of the Bluetooth signal from the Bluetooth signal; acquiring a received signal strength value when the Bluetooth device receives the Bluetooth signal; and determining the loss of the Bluetooth signal according to the insertion loss value, the transmitting power value and the receiving signal intensity value, and determining the distance between the Bluetooth device and the device to be measured according to the loss of the Bluetooth signal.

According to the technical scheme, the insertion loss value is set according to the Bluetooth modes, so that the calculated loss values of Bluetooth signals in different Bluetooth modes are the same, and therefore the calculated distances of the Bluetooth devices in different Bluetooth modes can be kept consistent, and the measured distance results can be kept consistent even if the radio frequency performance or the same-frequency interference and the channel interference corresponding to the different Bluetooth modes are different.

In an embodiment of the present application, the bluetooth mode of the bluetooth device includes an independent bluetooth mode and a dependent bluetooth mode, where the independent bluetooth mode refers to that the bluetooth device independently receives and transmits the bluetooth signal through the antenna, and the dependent bluetooth mode refers to that the bluetooth device multiplexes the antenna to perform Wi-Fi signal and receive and transmit the bluetooth signal. In the above technical scheme, the bluetooth device independently transmits and receives bluetooth signals through the antenna in an independent bluetooth mode to perform distance measurement, and the bluetooth device multiplexes the antenna to transmit and receive bluetooth information in a dependent bluetooth mode to perform distance measurement.

In an embodiment of the present application, the determining the insertion loss value of the bluetooth device according to the bluetooth mode includes: if the Bluetooth mode is an independent Bluetooth mode, setting the insertion loss value of the Bluetooth device as a first value; and if the Bluetooth mode is a non-independent Bluetooth mode, setting the insertion loss value of the Bluetooth device to be a second value, wherein the first value is larger than the second value. It should be noted that, if the radio frequency performance of the antenna of the bluetooth device in the independent bluetooth mode is better than the radio frequency performance of the antenna in the non-independent bluetooth mode, the first value may also be smaller than the second value. This is by way of example only and not by way of limitation. According to the technical scheme, the insertion loss value of the Bluetooth device can be dynamically adjusted according to the Bluetooth mode of the Bluetooth device, so that the measured distance results of the Bluetooth device in different Bluetooth modes are consistent.

In one embodiment of the present application, the first value is 15dbm and the second value is 10dbm. According to the technical scheme, the insertion loss value of the Bluetooth device in the independent Bluetooth mode is set to be 15dbm, and the insertion loss value of the Bluetooth device in the non-independent Bluetooth mode is set to be 10dbm, so that the effect that the measured distance results of the Bluetooth device in different Bluetooth modes are consistent is optimal.

In an embodiment of the present application, the acquiring the received signal strength value when the bluetooth signal is received includes: and acquiring the intensity indication RSSI of a received signal from the Bluetooth signal as the intensity value of the received signal.

In the above technical solution, since the co-channel interference and the channel interference of the bluetooth devices in different service scenarios are different, the received signal strength values of the bluetooth signals received by the bluetooth devices in different service scenarios are also different, resulting in different loss values of the received bluetooth signals. In order to ensure that the calculated distance values of the Bluetooth equipment in different service scenes are kept consistent, different insertion loss values are set according to different service scenes, so that the calculated loss values of the Bluetooth equipment in different service scenes are kept consistent, and the calculated distance results of the Bluetooth equipment in different service scenes are kept consistent.

According to the technical scheme, the first service scene, the second service scene and the third service scene are determined according to Wi-Fi service data and the Bluetooth service data, and the insertion loss value of the Bluetooth device is dynamically adjusted according to the service scenes so that the measured distance results of the Bluetooth device under different service scenes are consistent.

In an implementation of the present application, the determining the insertion loss value of the bluetooth device according to the Wi-Fi service data and the bluetooth service data includes: if the Wi-Fi service data and the Bluetooth service data do not exist in the Bluetooth equipment, determining that the service scene is the first service scene; if the Bluetooth device has the Wi-Fi service data but does not have the Bluetooth service data, determining that the service scene is the second service scene; if the Wi-Fi service data and the Bluetooth service data exist in the Bluetooth equipment, determining that the service scene is the third service scene; the first value is less than the second value, and the second value is less than the third value.

At present, before leaving the factory, bluetooth devices such as mobile phones and the like need to be placed in a certain distance range for various functional tests, for example, the connection response function of the mobile phones and bluetooth headphones is tested in the certain distance range. However, when the mobile phone processes different service data under different hardware configuration conditions, the radio frequency performance or the same frequency interference and the channel interference of the mobile phone are different, so that the strength values of the received signals received by the mobile phones with different hardware configurations or the mobile phones under different service data are also different, and inconsistent distance results can be obtained in the ranging of the mobile phones. However, when the mobile phone performs the function test according to the tested distance result, the function test result of the mobile phone is inaccurate and unreliable due to the inaccuracy and inconsistency of the tested distance result, which affects the function test efficiency of the mobile phone. For example, when the mobile phone is close to the bluetooth headset to test the connection response function of the mobile phone and the bluetooth headset, when the mobile phone is close to the bluetooth headset for 10 times within the preset distance range according to the distance tested by the mobile phone, the experimental data of the time when the mobile phone responds to the bluetooth headset and performs bluetooth connection is 4.91s,9.24s,30.52s, connection failure, 32.37s,23.92s,13.74s,7.63s,19.60s, and connection failure, respectively. However, under the existing standard, when the mobile phone approaches the bluetooth headset to within a preset distance range, the time for the mobile phone to respond to the bluetooth headset is 1s-2s. Obviously, the result of the function test of the mobile phone is also inaccurate and unreliable due to the inaccuracy and inconsistency of the result of the test distance.

In order to solve the technical problems of inaccurate and inconsistent results of the distance test, the application provides a Bluetooth ranging method. The Bluetooth ranging method is applied to Bluetooth equipment. Referring to fig. 1, an application scenario diagram of a bluetooth ranging method in an embodiment of the present application is shown. The bluetooth device 10 is in communication with a device under test 20. The bluetooth device 10 is configured to receive a bluetooth signal of the device to be measured 20, and determine a distance between the bluetooth device 10 and the device to be measured 20 according to the bluetooth signal, its own hardware configuration, or currently processed service data.

In fig. 1, a mobile phone is used as a bluetooth device 10, a bluetooth headset is used as a device to be tested 20, and an application scenario of a bluetooth ranging method is illustrated. For example, in other embodiments of the present application, the Bluetooth device 10 may also be a tablet, desktop, laptop, handheld, notebook, ultra-mobile personal computer (UMPC), netbook, and a cellular telephone, personal digital assistant (personal digital assistant, PDA), augmented reality (augmented reality, AR) device, virtual Reality (VR) device, artificial intelligence (artificial intelligence, AI) device, wearable device, in-vehicle device, smart home device, and/or smart city device, among other devices having Bluetooth communication capabilities. The device 20 to be measured may be a sound box, a wearable device, a vehicle-mounted device, an intelligent home device, or the like with a bluetooth communication function.

Referring to fig. 2, a flowchart of a bluetooth ranging method according to an embodiment of the present application is shown. It should be further noted that the method disclosed in the embodiments of the present application or the method shown in the flowchart, including one or more steps for implementing the method, may be performed in an order that the steps may be interchanged with one another, and some steps may be deleted without departing from the scope of the claims. Some embodiments will be described below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without conflict. The Bluetooth ranging method comprises the following steps.

Step S201, when the Bluetooth ranging is started, determining the Bluetooth mode of the Bluetooth device according to the configuration information of the antenna of the Bluetooth device.

In one embodiment of the present application, a system app (application) application of the bluetooth device 10 (e.g., a mobile phone) may monitor whether the bluetooth device 10 is on screen, and invoke the bluetooth ranging function if the bluetooth device 10 is monitored to be on screen. The bluetooth ranging function may calculate the distance between devices based on bluetooth information received by the devices. In another embodiment of the present application, the app application of the bluetooth device 10 may receive an operation instruction of the user to initiate bluetooth ranging, and the user may input the operation instruction in the app application through physical keys, virtual keys, voice, gesture actions to initiate bluetooth ranging.

In an embodiment of the present application, the bluetooth mode includes an independent bluetooth mode and a dependent bluetooth mode. The independent bluetooth mode refers to that the bluetooth device 10 independently transmits and receives bluetooth signals through an antenna, such as transmitting and receiving bluetooth signals transmitted from the device to be measured 20. The non-independent bluetooth mode refers to that the bluetooth device 10 multiplexes the antenna to transmit and receive Wi-Fi signals and bluetooth signals. In an embodiment of the present application, determining the bluetooth mode of the bluetooth device according to the configuration information of the antenna of the bluetooth device 10 includes: if the configuration information of the antenna of the Bluetooth device 10 is that the antenna independently receives and transmits Bluetooth signals, determining that the Bluetooth mode is an independent Bluetooth mode; if the configuration information of the antenna of the bluetooth device 10 is that the antenna is used to transmit and receive Wi-Fi signals and bluetooth signals, it is determined that the bluetooth mode is an independent bluetooth mode.

Step S202, determining the insertion loss value of the bluetooth device 10 according to the bluetooth mode.

In an embodiment of the present application, a table of insertion loss value relationships is preset in the bluetooth device 10. The insertion loss value relation table comprises different types of Bluetooth modes and insertion loss values corresponding to the different Bluetooth modes. The bluetooth device 10 may determine the corresponding insertion loss value according to the bluetooth mode and insertion loss value relationship table. FIG. is a schematic diagram of a table of insertion loss value relationships according to an embodiment of the present application. As shown in fig. 3, the insertion loss value corresponding to the independent bluetooth mode is 15dbm, and the insertion loss value corresponding to the non-independent bluetooth mode is 10dbm. When the bluetooth mode of the bluetooth device 10 is the independent bluetooth mode, the insertion loss value of the bluetooth device 10 is set to 15dbm according to the insertion loss value relationship table. When the bluetooth mode of the bluetooth device 10 is the dependent bluetooth mode, the insertion loss value of the bluetooth device 10 is set to 15dbm according to the insertion loss value relationship table.

In step S203, the bluetooth signal sent by the device to be measured 20 is received, and the transmission power value of the bluetooth signal is obtained from the bluetooth signal.

In an embodiment of the present application, if the distance-to-be-measured device 20 enters the bluetooth communication range, the distance-to-be-measured device 20 carries a transmission power value for transmitting the bluetooth signal in the bluetooth signal, and transmits the bluetooth signal to the bluetooth device 10. For example, the distance to be measured device 20 carries the transmission power value for transmitting the bluetooth signal in a preset field in the data frame of the bluetooth signal, and transmits the data frame of the bluetooth signal to the bluetooth device 10. After receiving the data frame of the bluetooth signal, the bluetooth device 10 obtains the transmission power value of the device 20 to be measured from the data frame.

In step S204, the received signal strength value when the bluetooth device 10 receives the bluetooth signal is obtained.

In an embodiment of the present application, the bluetooth device 10 is capable of obtaining a strength indication (Received Signal Strength Indicator, RSSI) of a received signal from a received bluetooth signal, and taking the obtained strength indication of the received signal as a received signal strength value.

In step S205, the loss of the bluetooth signal is determined according to the insertion loss value, the transmission power value and the received signal strength value, and the distance between the bluetooth device 10 and the device 20 to be measured is determined according to the loss of the bluetooth signal.

In one embodiment of the present application, the loss includes an energy loss of the electromagnetic wave when it propagates in the air. Determining the loss of the bluetooth signal according to the insertion loss value, the transmission power value and the received signal strength value comprises: according to the formulaCalculating a distance between the Bluetooth device 10 and the device 20 to be measured, whereinRepresenting the actual transmit power value,/, and>representing insertion loss value->Representing the received signal strength value,/->Indicating loss of bluetooth signal. In an embodiment of the present application, the determining the distance between the bluetooth device and the device to be measured according to the loss of the bluetooth signal includes: according to the formula->Calculating the distance between the Bluetooth device 10 and the device to be measured 20, wherein +.>Represents the calculated distance in Km.

In the experimental test of the application, the transmission power value of the bluetooth headset as the device to be measured 20 to the mobile phone (as the bluetooth device 10) is fixed, and the specific value is-3 dbm. In the independent Bluetooth mode, the received signal strength value of the received Bluetooth signal is-60 dbm. Thus, the LOSs value of the bluetooth signal received by the handset in the independent bluetooth mode may be expressed as los= - (-3) -Lin- (-60) =63-Lin. In the non-independent Bluetooth mode, the received signal strength value of the received Bluetooth signal of the mobile phone is-65 dbm, and correspondingly, the LOSs value of the received Bluetooth signal of the mobile phone in the non-independent Bluetooth mode can be expressed as LOS= - (-3) -Lin- (-65) =68-Lin. Thus, it can be seen that the loss value of the bluetooth signal received by the mobile phone in the non-independent mode is 5dbm higher than that of the bluetooth signal received by the mobile phone in the independent mode, so that the calculated distances of the mobile phones in the two bluetooth modes are inconsistent.

Based on the above embodiment, in order to solve the problem that the distance between the bluetooth device 10 (e.g., mobile phone) and the device 20 to be measured is not consistent, the insertion LOSs value (i.e., lin) may be set according to the bluetooth mode, specifically, the insertion LOSs value corresponding to the non-independent mode is set to 15dbm, the insertion LOSs value corresponding to the independent mode is set to 10dbm, so that the LOSs value of the bluetooth signal received by the mobile phone in the non-independent mode is calculated to los=68-15=53 dbm, and the LOSs value of the bluetooth signal received by the mobile phone in the independent mode is calculated to los=63-10=53 dbm. Therefore, according to the method and the device, the loss values of the calculated Bluetooth signals in the two Bluetooth modes are the same, so that the calculated distances of the mobile phones in the two Bluetooth modes can be kept consistent, and the calculated distance results can be kept consistent even if the radio frequency performance corresponding to the different Bluetooth modes of the mobile phones is different.

Referring to fig. 4, a flowchart of a bluetooth ranging method according to another embodiment of the present application is shown. The method comprises the following steps.

Step S401, when Bluetooth ranging is started, wi-Fi service data and Bluetooth service data are acquired.

The specific implementation of starting bluetooth ranging may refer to the description of step S201 of fig. 2, and the description will not be repeated here.

In an embodiment of the present application, the Wi-Fi service data refers to data uploading and data downloading by the bluetooth device in a Wi-Fi internet surfing mode, for example, uploading or downloading data such as pictures, audio, images, text, etc. in a Wi-Fi internet surfing mode. The bluetooth service data refers to data transmitted by the bluetooth device through a bluetooth communication mode, for example, audio data transmitted through the bluetooth communication mode.

Step S402, determining the insertion loss value of the bluetooth device 10 according to the Wi-Fi service data and the bluetooth service data.

In an embodiment of the present application, the bluetooth device 10 can determine different service scenarios according to Wi-Fi service data and bluetooth service data, because co-channel interference and channel interference of the bluetooth device 10 are also different in different service scenarios. In an embodiment of the present application, the bluetooth device 10 sets different insertion loss values according to different service scenarios. The method for determining the insertion loss value of the bluetooth device 10 according to the Wi-Fi service data and the bluetooth service data may refer to the following detailed specific flow shown in fig. 5.

In step S403, the bluetooth signal sent by the device to be measured 20 is received, and the transmission power value of the bluetooth signal is obtained from the bluetooth signal.

In step S404, the received signal strength value when the bluetooth device 10 receives the bluetooth signal is obtained.

In step S405, the loss of the bluetooth signal is determined according to the insertion loss value, the transmission power value and the received signal strength value, and the distance between the bluetooth device 10 and the device 20 to be measured is determined according to the loss of the bluetooth signal.

The specific implementation of steps S403 to S405 in the present application may refer to the description of steps S203 to S205 in fig. 2, and the description will not be repeated here.

In this embodiment of the present application, since the co-channel interference and the channel interference of the bluetooth device 10 in different service scenarios have differences, the received signal strength values of the bluetooth signals received by the bluetooth device 10 in different service scenarios are also different, resulting in different loss values of the received bluetooth signals, and in order to ensure that the distance values calculated by the bluetooth device 10 in different service scenarios are consistent, different insertion loss values are set according to different service scenarios, so that the loss values calculated by the bluetooth device 10 in different service scenarios are consistent, and the distance results calculated by the bluetooth device 10 in different service scenarios are consistent.

Referring to fig. 5, a flowchart of determining an insertion loss value of a bluetooth device according to an embodiment of the present application is shown, specifically, determining an insertion loss value of a bluetooth device according to Wi-Fi service data and bluetooth service data, including the following steps:

Step S501, a service scene is determined according to Wi-Fi service data and Bluetooth service data.

In an embodiment of the present application, the service scenario at least includes a first scenario, a second scenario, and a third scenario. Fig. 6 is a schematic diagram of a bluetooth device in a first scenario according to an embodiment of the present application. In an embodiment of the present application, if the bluetooth device 10 does not have Wi-Fi service data and bluetooth service data, the service scenario is determined to be the first service scenario. Referring to fig. 7, a schematic diagram of a bluetooth device in a second scenario according to an embodiment of the present application is shown. If the bluetooth device 10 has Wi-Fi service data but does not have bluetooth service data, determining that the service scenario is a second service scenario. Referring to fig. 8, a schematic diagram of a bluetooth device in a third scenario according to an embodiment of the present application is shown. If the bluetooth device 10 has Wi-Fi service data and bluetooth service data at the same time, determining that the service scenario is a third service scenario. In an embodiment of the present application, the service scenario further includes a fourth scenario. If the bluetooth device 10 does not have Wi-Fi service data, but has bluetooth service data, the service scenario is determined to be a fourth service scenario.

Step S502, determining insertion loss values corresponding to the service scenes according to different service scenes, wherein the insertion loss value corresponding to the first service scene is a first value, the insertion loss value corresponding to the second service scene is a second value, and the insertion loss value corresponding to the third service scene is a third value.

If the bluetooth device 10 does not have Wi-Fi service data or bluetooth service data, it indicates that the bluetooth device 10 is in a ranging scenario with less interference, and the bluetooth device 10 sets the insertion loss value (i.e., the first value) of the first service scenario to be smaller. If Wi-Fi service data is present, but bluetooth service data is not present, it indicates that the existing Wi-Fi service data may have an influence on the bluetooth ranging function, and the bluetooth device 10 sets an insertion loss value (i.e., a second value) of the second service scenario higher than that of the first service scenario. If the bluetooth device 10 has both insertion loss value data and bluetooth service data of the second service scenario of the Wi-Fi service, it indicates that both the Wi-Fi service data and the bluetooth service data that are simultaneously present may have an influence on the bluetooth ranging function, and the bluetooth device 10 sets an insertion loss value (i.e., a third value) of a third service scenario, where the insertion loss value of the third service scenario is higher than the insertion loss value of the second scenario. If the bluetooth device 10 does not have Wi-Fi service data, but has bluetooth service data, the specification bluetooth service data may have an effect on the bluetooth ranging function, and the bluetooth device 10 sets the insertion loss value of the fourth service scenario to a fourth value. Wherein the fourth value is less than the third value but greater than the first value.
