Before the first electronic device 101 is lost, the first electronic device 101 may bind the device information with the first account in response to a user operation. That is, the association relationship between the device information of the first electronic device 101 and the first account can be stored on the cloud server 102. This association relationship can be used by another electronic device (for example, the second electronic device 103) to obtain the positioning information of the first electronic device 101 from the cloud server 102. The first account can be logged in to the first electronic device 101.

For example, the device information of the first electronic device 101 may be a media access control (MAC) address, and the first account is, for example, a Huawei account "136********". After binding, the cloud server 102 stores the association relationship between the MAC address of the first electronic device 101 and the Huawei account number "136********". The cloud server 102 may also store verification information (such as a login password) corresponding to the Huawei account "136********", which is used to verify the login request.

The cloud server 102 may be used to store the association relationship between the device information of the first electronic device 101 and the first account. The cloud server 102 may also store the verification information of the first account. The cloud server 102 can also obtain the positioning information of the first electronic device 101.

The second electronic device 103 can also log in to the first account.

The first electronic device 101 may be in a boot-up state, and may send the positioning information of the first electronic device 101 to the cloud server 102. In this way, the cloud server 102 can send the positioning information of the first electronic device 101 to the second electronic device 103 according to the association relationship between the device information of the first electronic device 101 and the first account in response to the received request. Thus, when the first electronic device 101 is lost, the second electronic device 103 obtains the positioning information of the first electronic device 101.

In the embodiment of the present application, both the first electronic device 101 and the second electronic device 103 may be devices such as mobile phones, smart bracelets, tablets, smart watches, etc., which are not limited in the embodiments of the present application.

After the first electronic device 101 is lost, it cannot perform positioning and cannot send its own positioning information to the cloud server. In this way, it is not conducive for the user to obtain the location of the first electronic device.

In order to improve the accuracy of positioning, an embodiment of the present application provides a positioning system and a positioning method. The positioning system is used for the aforementioned first electronic device 101, and the positioning system includes a processor and an Internet of Things chip. The processor may be used to obtain positioning information from the positioning chip and send it to the cloud server through the antenna when the first electronic device is turned on. When the first electronic device 101 is in the shutdown state, the IoT chip can obtain positioning information from the positioning chip and send it to the cloud server through the antenna. In this way, even if the first electronic device is in the shutdown state, the positioning information can still be sent to the cloud server to inform the user. In this way, the situation that the positioning information cannot be obtained after the first electronic device is lost is reduced, and the accuracy and convenience of positioning are improved.

S113. The cloud server 102 sends the second positioning information to the second electronic device 103.

In steps S108-S113, when the lost first electronic device 101 is shut down, the IoT chip 301 in the first electronic device 101 can still be in working state, and can obtain real-time positioning information from the positioning chip, and send it to Cloud server to achieve positioning. In this way, the situation that the user cannot obtain the real-time positioning information of the lost device when the lost device is shut down is reduced, and the convenience of device positioning is improved.

In some embodiments of the present application, after step S108, after the battery 303 and the IoT chip 301 are turned on, the IoT chip 301 can work in any of three modes: active and standby. , Deep sleep (deepsleep).

Wherein, in the active mode, the IoT chip 301 can periodically obtain positioning information and send it to the cloud server 102. When the second electronic device 103 receives the first request, it can directly obtain the positioning information of the first electronic device 101 from the cloud server 102. Compared with the other two modes, the power consumption is the largest in the active mode. In the standby mode, the IoT chip 301 can still work under the working clock, can increase the period of sending positioning information, or send the positioning information only when the second request is received. The power consumption in standby mode is less than in active mode and greater than in deep sleep mode. In the deep sleep mode, the IoT chip 301 can be in a sleep state under the action of the sleep clock signal. The IoT chip 301 can periodically wake up to the working state (the clock signal is switched to the working clock signal), and obtain real-time positioning information and send it to the cloud server 102. Or, when the IoT chip receives the second request, it wakes up and obtains the positioning information and sends it to the cloud server. Compared with the other two modes, the deep sleep mode has the least power consumption.

Specifically, in a possible implementation manner, when the second request is not received, the IoT chip 301 may be in a standby state or a deep sleep state. For example, first, the IoT chip 301 is in a standby state, and the second request is not received within a first set time, then the IoT chip 301 enters a deep sleep state. When the second request is received through the antenna, the second request is used to obtain the positioning information of the first electronic device 101, and the IoT chip 301 can enter the activated state. When the second request is not received for the second set time, the IoT chip 301 may enter the standby state. When the duration of the standby state is greater than or equal to the first set time, the IoT chip 301 may enter a deep sleep state.

In the foregoing implementation manner, the IoT chip 301 may be in a standby state or a deep sleep state when it does not receive a request for obtaining positioning information, so as to save power consumption. In this way, the battery life of the electronic device can be increased without affecting the reporting of positioning information.

In another possible implementation manner, the IoT chip 301 can also obtain the remaining power of the battery 303 and adjust the working mode according to the remaining power of the battery 303. For example, when the remaining power is greater than or equal to a set threshold (for example, 30% remaining), the IoT chip 301 may be in an active state or a standby state. When it is detected that the remaining power is less than the set threshold, the IoT chip 301 can work in a deep sleep mode. It is not limited to setting one battery remaining power threshold, and it can also be multiple. For example, when the remaining power is greater than or equal to the first set threshold (for example, 50% remaining), the IoT chip 301 may be in an activated state. When the remaining power is greater than or equal to the second set threshold (for example, the remaining 10%) and less than the first set threshold, the IoT chip 301 can be switched from the active state to the standby state. When the remaining power is less than the second set threshold, the IoT chip 301 can switch from the standby state to the deep sleep state.

In the embodiment of the present application, the first electronic device 101 may enter the shutdown state from the startup state when the remaining power of the battery 303 is lower than the set threshold. Generally, the set threshold is, for example, the remaining 3%. In the embodiment of the present application, in order to ensure that sufficient remaining power is supplied to the IoT chip 301, the positioning chip and the antenna, the remaining power setting threshold of the first electronic device 101 is, for example, 8%, which is higher than the aforementioned 3%. It is understandable that the above example of setting a threshold value for the remaining power is only used to explain the embodiment of the present application, and should not constitute a limitation.

In the embodiment of the present application, the second positioning information may be the same as or different from the first positioning information.

S118. The processor 302 instructs one or more of the Bluetooth, GPS, Wi-Fi chip 304, and the Beidou positioning chip 305 to perform positioning to obtain third positioning information.

S119. The processor 302 sends third positioning information to the cloud server 102 through the antenna.

S120. The server 102 sends the third positioning information to the second electronic device 103.

In some embodiments of the present application, the antenna switch 1, the antenna switch 2, the chip switch, and the power switch 1 in steps S115 to S117 may be controlled by the processor 302 to implement steps S115 to S117.

The following describes the positioning principles in several scenarios provided by the embodiments of the present application.

When the first electronic device 101 is in a power-on state, the first electronic device 101 can obtain positioning information through the positioning of the positioning chip. The processor 302 in the first electronic device 101 may select a network with good signal quality (for example, the signal strength is greater than the first strength threshold) to send the positioning information according to the connection status of the network signal. When the first electronic device 101 is in the shutdown state and the processor 302 is in the dormant state, the IoT chip 301 in the first electronic device 101 can also select the signal quality to be good (for example, the signal strength is greater than the first strength) according to the connection status of the network signal. Threshold) to send location information to the network. The following describes the positioning principle in the startup state and the shutdown state.

(1) Positioning principle under startup state

The following is introduced in conjunction with Table 1. Please refer to Table 1. Table 1 is an example of a positioning principle in a startup state of a first electronic device according to an embodiment of the present application.

Table 1 is an example of the positioning principle in the startup state of the first electronic device provided by the embodiment of the present application

As shown in Table 1, in scenario 1, when the signal quality of the cellular network is good (for example, the signal strength is greater than the first intensity threshold), the processor can obtain positioning information from the positioning chip, and send the positioning information to the cloud through the cellular network Server 102. The positioning method is, for example, any one or more of GPS positioning/Wi-Fi positioning/Bluetooth positioning/Beidou positioning.

In scenario 2, the signal quality of the cellular network is poor (for example, the signal strength is less than the first intensity threshold), and the signal quality of the Internet of Things (IoT) is good (for example, the signal strength is greater than the second intensity threshold). For example, the user carries the first electronic device. The device 101 is in an underground garage, basement or other place where the signal quality of the cellular network is poor. When it is detected that the signal strength of the cellular network signal is less than the first strength threshold, in the startup state, the processor can control the power switch 1 to turn on the battery 303 and the IoT chip 301, and control the antenna switch to connect the IoT chip and the antenna The connection between the chip is turned on, and the chip switch is controlled to turn on the connection between the IoT chip 301 and the positioning chip. For details, refer to steps S108 to S110 in the example described in FIG. 4. The IoT chip can obtain positioning information through any one or more of the following: GPS positioning/Wi-Fi positioning/Bluetooth positioning/Beidou positioning, and send positioning information to the cloud server 102 through the IoT network.

In scenario 3, both the cellular network signal and the IoT signal quality are not good. For example, the signal strength of the cellular network signal is less than the first strength threshold, and the signal strength of the IoT signal is less than the second strength threshold. When it is detected that the signal strength of the cellular network signal is less than the first strength threshold and the signal strength of the IoT signal is less than the second strength threshold, the processor may perform Beidou positioning through the Beidou positioning chip 305 to obtain positioning information. The processor may also send the positioning information to the cloud server 102 through the antenna connected to the Beidou positioning chip 305 (ie, the Beidou antenna). The Beidou positioning chip 305 and the Beidou antenna may refer to the Beidou positioning chip 305 and the antenna k+1 in the example described in FIG. 7. In scenario 3, it is not limited to obtaining positioning information through Beidou positioning, and the processor may also obtain positioning information through GPS positioning/Wi-Fi positioning/Bluetooth positioning.

In scenario 4, the quality of the cellular network signal and the signal of the Internet of Things is poor, and the quality of the Beidou positioning signal is also poor. For example, the signal strength of the cellular network signal is less than the first strength threshold, the signal strength of the IoT signal is less than the second strength threshold, and the signal strength of the Beidou positioning signal is less than the third strength threshold. When it is detected that the signal strength of the cellular network signal is less than the first strength threshold, the signal strength of the IoT signal is less than the second strength threshold, and the signal strength of the Beidou positioning signal is less than the third strength threshold, the processor can obtain positioning through Bluetooth positioning information. When sending the positioning information, the processor may send a Bluetooth broadcast carrying the positioning information through the Bluetooth module and the antenna, and a device that receives the Bluetooth broadcast around the first electronic device sends the positioning information to the cloud server. In scenario 4, it is not limited to obtain positioning information through Bluetooth positioning, and the processor may also obtain positioning information through GPS positioning/Wi-Fi positioning/Beidou positioning.

In the above-mentioned positioning solution in the startup state, when the signal quality of the cellular network is poor, the processor may send positioning information in other ways. In this way, when the first electronic device is in an environment where the signal quality of the cellular network is not good, or the signal quality of the Internet of Things is not good, or the quality of the Beidou positioning signal is not good, the first electronic device can send the positioning information to the cloud server , The server sends to the second electronic device to inform the user of the location information of the first electronic device. In this way, the situation that the positioning information cannot be obtained after the first electronic device is lost is reduced, and the convenience of positioning is improved.

(2) Positioning principle in shutdown state

The following is introduced in conjunction with Table 2. Please refer to Table 2. Table 2 is an example of the positioning principle in the shutdown state of the first electronic device according to an embodiment of the present application.

Table 2 is an example of the positioning principle in the shutdown state of the first electronic device provided by the embodiment of the present application

Compared with the scenario described in Table 1, the first electronic device in Table 2 is in the shutdown state, and the processor in the first electronic device sleeps, and the IoT chip replaces the processor to obtain positioning information and send it out through the antenna.

Specifically, in a possible embodiment, the Internet of Things chip supports the Internet of Things network and also supports the cellular network. As shown in Scenario 5 in Table 2, when the cellular network signal quality is good (for example, the signal strength is greater than the intensity threshold), the IoT chip can obtain positioning information from the positioning chip, and send the positioning information to the cloud server 102 via the cellular network. The positioning method is, for example, any one or more of GPS positioning/Wi-Fi positioning/Bluetooth positioning/Beidou positioning.

In scenario 6, the signal quality of the cellular network is poor (for example, the signal strength is less than the first intensity threshold), and the signal quality of the Internet of Things is good (for example, the signal strength is greater than the second intensity threshold). For example, the user carries the first electronic device 101 that is turned off in an underground garage. , Or other places where the signal quality of the cellular network is not good. When it is detected that the signal strength of the cellular network signal is less than the first strength threshold, the IoT chip can obtain positioning information through any one or more of the following: GPS positioning/Wi-Fi positioning/Bluetooth positioning/Beidou positioning, and through the Internet of Things The network sends positioning information to the cloud server 102.

In scenario 7, the quality of the cellular network signal and the IoT signal is not good. For example, the signal strength of the cellular network signal is less than the first strength threshold, and the signal strength of the IoT signal is less than the second strength threshold. When it is detected that the signal strength of the cellular network signal is less than the first strength threshold, and the signal strength of the IoT signal is less than the second strength threshold, the IoT chip can perform Beidou positioning through the Beidou positioning chip 305 to obtain positioning information. The IoT chip can also send positioning information to the cloud server 102 through an antenna connected to the Beidou positioning chip 305 (ie, the Beidou antenna). The Beidou positioning chip 305 and the Beidou antenna may refer to the Beidou positioning chip 305 and the antenna k+1 in the example described in FIG. 7. In scenario 7, it is not limited to obtaining positioning information through Beidou positioning. The IoT chip can also obtain positioning information through GPS positioning/Wi-Fi positioning/Bluetooth positioning.

In scenario 8, the quality of the cellular network signal and the signal of the Internet of Things is poor, and the quality of the Beidou positioning signal is also poor. For example, the signal strength of the cellular network signal is less than the first strength threshold, the signal strength of the IoT signal is less than the second strength threshold, and the signal strength of the Beidou positioning signal is less than the third strength threshold. When it is detected that the signal strength of the cellular network signal is less than the first strength threshold, the signal strength of the IoT signal is less than the second strength threshold, and the signal strength of the Beidou positioning signal is less than the third strength threshold, the IoT chip can be obtained through Bluetooth positioning Positioning information. When sending positioning information, the IoT chip can send a Bluetooth broadcast carrying the positioning information through a Bluetooth module and an antenna, and devices that receive the Bluetooth broadcast around the first electronic device send the positioning information to the cloud server. In Scenario 8, it is not limited to obtaining positioning information through Bluetooth positioning. The IoT chip can also obtain positioning information through GPS positioning/Wi-Fi positioning/Beidou positioning.

In the above positioning solution in the shutdown state, when the network signal quality is poor, the IoT chip can send positioning information in other ways. In this way, not only can the first electronic device be shut down and still be able to send its own positioning information, when the shut down first electronic device is in an environment with poor cellular network signal quality, or an environment with poor IoT signal quality, or Beidou positioning signal In a poor-quality environment, the first electronic device can also send location information to the cloud server, and the server can send the location information to the second electronic device to inform the user of the location information of the first electronic device. In this way, the situation that the positioning information cannot be obtained after the first electronic device is lost is reduced, and the convenience of positioning is improved.

In the embodiment of the present application, the first electronic device 101 may not need to send the positioning information to the second electronic device 103 via the cloud server 102. A short-range wireless connection can be established between the first electronic device 101 and the second electronic device 103, such as a Wi-Fi direct connection or a Bluetooth connection. The first electronic device 101 can send positioning information to the second electronic device 103 through the short-range wireless connection.

Specifically, the second electronic device 103 and the first electronic device 101 may both log in to the first account. The cloud server 102 may store the association relationship between the device information of the first electronic device 101 and the first account. The second electronic device 103 can obtain the device information of the first electronic device 101 through the cloud server 102 and establish a short-distance wireless connection with the first electronic device 101. When the user forgets where the first electronic device 101 is placed, he can click the search device control on the user interface of the second electronic device 103. In response to the user operation, the second electronic device 103 may send an instruction for obtaining positioning information to the first electronic device 101 through a short-range wireless connection. In the power-on state, in response to the instruction, the processor in the first electronic device 101 obtains positioning information, and sends the positioning information to the second electronic device 103 via the antenna through the short-range wireless connection. In the off state or the cellular network signal quality is poor, the IoT chip in the first electronic device 101 can obtain positioning information, and send the positioning information to the second electronic device 103 through the short-range wireless connection via the antenna.

In a possible embodiment, the first electronic device may carry an identifier when sending positioning information to the cloud server, and the identifier may indicate whether the first electronic device is currently shut down, signal quality, power level, and so on. When the cloud server sends the positioning information to the second electronic device, the identification may also be sent to the second electronic device. The second electronic device may display a prompt, which may indicate whether the first electronic device is currently turned off, whether the signal quality is good or bad, and so on.

Specifically, please refer to FIGS. 9A to 9D. FIGS. 9A to 9D are schematic diagrams of some user interfaces provided by embodiments of the present application. As shown in FIG. 9A, the second electronic device can display a user interface 100. The user interface 100 is, for example, a user interface for searching a mobile phone application. The second electronic device and the first electronic device can both be searching for a mobile phone application and log in to the first account. . As shown in FIG. 9A, the user interface 100 may include device options 1001. The device option 1001 may indicate the first electronic device.

In response to a user operation acting on the device option 1001, the second electronic device may send a first request to the cloud server. Specifically, the first request is associated with the first account, and the cloud server can find the device information of the device associated with the first account (for example, the device information of the first electronic device) according to the first request and the first account. The cloud server may send the second request to the first electronic device according to the device information of the first electronic device. After receiving the positioning information from the first electronic device, the cloud server sends the positioning information to the second electronic device. The positioning information, for example, carries an identifier, which indicates that the first electronic device is in a power-on state and the cellular signal quality is good. The identifier may also indicate the remaining power of the first electronic device, for example, 87%. In response to the received positioning information and identification, the second electronic device displays the user interface 200.

As shown in FIG. 9B, the user interface 200 may include a battery indicator 2001, a status indicator 2002, a device location indicator 2003, a navigation control 2004, a positioning control 2005, a ringing control 2006, a locking control 2007, and a data erasing control 2008. in:

The power prompt 2001 is used to prompt the current remaining power of the first electronic device, and the remaining power can be carried in the identifier and sent from the first electronic device via the cloud server, for example, the remaining power is 87%.

The status prompt 2002 is used to prompt whether the first electronic device is currently turned on and the signal quality is good or bad. For example, it prompts "The device is on and online." Similarly, the status can also be carried in the identifier and sent from the first electronic device via the cloud server. For example, the first electronic device is currently in a power-on state and the cellular network signal is good. At this time, the processor in the first electronic device is in a working state, and the processor can obtain positioning information and send the positioning information, device status, power, etc. to the cloud server through the antenna. At this time, the IoT chip in the first electronic device may be in a dormant state.

The positioning control 2005 is used to retrieve the positioning information of the first electronic device.

The ringing control 2006 is used to send a ringing instruction to the first electronic device via the cloud server. In response to a user operation on the ringing control 2006, the second electronic device may send a ringing instruction to the cloud server, and the cloud server may forward the ringing instruction to the first electronic device via the cellular network. The processor in the first electronic device can activate the speaker to ring according to the ringing instruction.

The lock control 2007 is used to send a lock instruction to the first electronic device via the cloud server. In response to a user operation on the lock control 2007, the second electronic device may send a lock instruction to the cloud server, and the cloud server may forward the lock instruction to the first electronic device via the cellular network. The processor in the first electronic device can lock the first electronic device according to the lock instruction. After the first electronic device is locked, the interface of the application is no longer displayed, for example, the photo album application, the payment application, etc. are locked and cannot be opened.

The data erasure control 2008 is used to send a data erasure instruction to the first electronic device via the cloud server. In response to a user operation on the data erasure control 2008, the second electronic device may send a data erasure instruction to the cloud server, and the cloud server may forward the data erasure instruction to the first electronic device via the cellular network. The processor in the first electronic device can delete the private data in the first electronic device according to the data erasure instruction. Private data includes, for example, image data, account data for application logins, and the like.

In the embodiment of the present application, in response to a user operation acting on the positioning control 2005, the second electronic device may resend the first request to the cloud server, and the cloud server may resend the second request to the first electronic device to obtain an updated device information. After receiving the updated positioning information from the first electronic device, the cloud server sends the updated positioning information to the second electronic device. The updated positioning information carries, for example, an updated identifier.

Exemplarily, if the signal quality of the cellular network of the first electronic device is poor (for example, the signal quality is lower than the first intensity threshold), in the first electronic device, the processor may control the switch to make the IoT chip 301 take over the positioning chip and the antenna. The IoT chip can obtain updated positioning information and updated identification, and send it to the cloud server. The update identifier indicates, for example, that the first electronic device is in a power-on state and the signal quality of the Internet of Things is good. The identifier may also indicate the remaining power of the first electronic device, for example, 85%. In response to the received updated positioning information and updated identification, the second electronic device refreshes the user interface 200.

As shown in FIG. 9C, on the refreshed user interface 200, the battery indicator 2001, the status indicator 2002, and the device location indicator 2003 are updated according to the updated identification. Power reminder 2001, can remind that the remaining power is 85%. Status prompt 2002, which can indicate "the device is turned on and the Internet of Things signal is online".

As shown in FIG. 9C, in response to a user operation on the ringing control 2006, the second electronic device may send a ringing instruction to the cloud server, and the cloud server may forward the ringing instruction to the first electronic device via the cellular network. The IoT chip in the first electronic device can activate the speaker to ring according to the ringing instruction. In the embodiment of the present application, the IoT chip can be connected to the speaker. In another possible implementation, the IoT chip can notify the processor, causing the processor to call the speaker to ring.

Similarly, for the user operation acting on the lock control 2007 and the user operation acting on the data erasure control 2008, the IoT chip can correspondingly lock the first electronic device and erase private data. In another possible implementation, the IoT chip can notify the processor (for example, wake up the processor), and the processor executes to lock the first electronic device and erase private data.

Exemplarily, on the user interface 200 shown in FIG. 9C, in response to a user operation acting on the positioning control 2005, the second electronic device may send the first request to the cloud server again, and the cloud server may send the first request to the first electronic device again. Send a second request to obtain the updated device information again. After receiving the re-updated positioning information from the first electronic device, the cloud server sends the re-updated positioning information to the second electronic device. The re-updated positioning information carries, for example, a re-updated identifier.

Exemplarily, if the first electronic device is in the shutdown state at this time, in the first electronic device, the processor may control the switch so that the IoT chip 301 takes over the positioning chip and the antenna. The IoT chip can obtain the updated positioning information and the updated identification again, and send them to the cloud server. The re-update indicator indicates, for example, that the first electronic device is in a shutdown state and the signal quality of the Internet of Things is good. The re-updated flag may also indicate the remaining power of the first electronic device, for example, 84%. In response to receiving the re-updated positioning information and the re-updated identification, the second electronic device refreshes the user interface 200.

As shown in FIG. 9D, on the user interface 200 that is refreshed again, the battery indicator 2001, the status indicator 2002, and the device location indicator 2003 are updated according to the re-updated identifier. Power reminder 2001, which can remind you that the remaining power is 84%. Status reminder 2002, which can indicate "the device is off and the Internet of Things signal is online".

The first electronic device can obtain positioning information through the IoT chip and send the positioning information to the cloud server. The server sends the positioning information to the second electronic device. In this way, the situation that positioning information cannot be obtained due to shutdown or low signal quality after the first electronic device is lost is reduced, and the convenience of positioning is improved.
