Description

Positioning method and related device

Technical Field

The present application relates to the field of electronic technologies, and in particular, to a positioning method and a related apparatus.

Background

At present, after electronic equipment such as a smart phone is lost, if the electronic equipment is in a startup state, the electronic equipment can send self positioning information to a cloud server. The user can access the cloud server through another electronic device to obtain the location information of the lost electronic device, so as to retrieve the lost electronic device.

However, if the lost electronic device is in a power-off state, the electronic device cannot perform positioning after being lost, and cannot send positioning information of the electronic device to the cloud server. Thus, it is not beneficial for the user to obtain the positioning information of the electronic device.

Disclosure of Invention

The application discloses a positioning method and a related device, which can improve the accuracy and the measurement efficiency of PPG signal measurement.

In a first aspect, an embodiment of the present application provides a positioning system, where the positioning system includes a processor, an internet of things chip, an antenna, and a positioning chip, where: the connection between the processor and the antenna is conducted through an antenna switch, and the connection between the processor and the positioning chip is conducted through a chip switch; the antenna switch is also connected with the Internet of things chip, and the chip switch is also connected with the Internet of things chip; the positioning chip is used for positioning to obtain first positioning information; the processor is used for obtaining the first positioning information from the positioning chip and sending the first positioning information through the antenna; the processor is also used for responding to user operation for shutdown, controlling the antenna switch to conduct connection between the Internet of things chip and the antenna, and controlling the chip switch to conduct connection between the Internet of things chip and the positioning chip; the positioning chip is used for positioning to obtain second positioning information; the internet of things chip is used for obtaining the second positioning information from the positioning chip through connection with the positioning chip and sending the second positioning information through connection with the antenna.

The first aspect of the implementation provides a positioning system, and even if a device including the positioning system is in a power-off state, the internet of things chip can still send positioning information to a cloud server through an antenna so as to inform a user of the positioning information. When the device including the positioning system is in a power-on state, the positioning system can also utilize the processor to send positioning information to the cloud server through the antenna. Therefore, the situation that the positioning information cannot be obtained after the equipment is lost is reduced, and the positioning accuracy and convenience are improved.

With reference to the first aspect, in some embodiments, the positioning system further includes a battery, the battery is connected to a power switch, and the power switch is connected to the internet of things chip; the processor is further used for responding to the user operation for shutdown, and controlling the power switch to conduct connection between the internet of things chip and the battery.

Wherein, the battery can be used for supplying power for the chip of the Internet of things.

The processor can control the power switch to communicate the battery with the Internet of things chip before the processor is in the sleep state, so that the Internet of things chip is still in the working state when the electronic equipment is in the shutdown state. When the processor receives a shutdown instruction, the processor can also control the antenna switch to disconnect the connection between the processor and the antenna before the processor is in a sleep state, and control the antenna switch to connect and disconnect the connection between the chip of the internet of things and the antenna. Therefore, in the power-off state, the internet of things chip can instruct the positioning chip (such as a bluetooth module, a GPS, a Wi-Fi module or a Beidou positioning chip) to position and send out positioning information through the antenna.

The receiving of the shutdown instruction by the processor may be a received user operation for shutdown (for example, long pressing of a power key), or may be detecting that the power level of the battery is lower than a set threshold.

With reference to the first aspect, in some embodiments, the positioning system further includes a crystal oscillator system, connected to the processor and connected to the internet of things chip, where: the crystal oscillator system is used for providing a clock signal for the chip of the Internet of things and providing a clock signal for the processor.

The crystal oscillator system is connected with the processor through a power chip and is connected with the Internet of things chip through the power chip. The power supply chip can also comprise a frequency division circuit which can divide the frequency of the clock signal output by the crystal oscillator to obtain clock signals with different frequencies. For example, the power chip divides the clock signal with the frequency f1 output by the crystal oscillator to obtain an operating clock signal with the frequency f2 and a sleep clock signal with the frequency f 3.

And when the electronic equipment is in a shutdown state, the working clock signal and the dormancy clock signal are respectively output to the chip of the Internet of things. Wherein: the working clock signal is used for providing a reference when the chip of the internet of things works (for example, when positioning information is sent through the antenna), so that all the modules work in a unified and synchronous mode. The frequency of the operating clock signal is for example 38 MHz.

The sleep clock signal can be continuously output to the chip or the processor of the internet of things in a power-off state, so that the continuity of time in the electronic equipment is maintained, and the reference of each module is provided when the working clock signal is not needed. The frequency of the sleep clock signal is, for example, 32.768 KHz.

In some embodiments of the present application, the clock signal with the frequency f1 output by the crystal oscillator system is divided by the power chip, and the clock signal can be provided for the processor.

When the electronic device is in a power-on starting state, the positioning system can send the first positioning information/the second positioning information to the cloud server, and the cloud server forwards the first positioning information/the second positioning information to the second electronic device. The positioning system may also send the first/second positioning information to the second electronic device.

(1) The positioning system sends the positioning information to the cloud server

The cloud server can store the association relationship between the device information of the first electronic device (including the positioning system) and the first account. When the electronic device is in a starting state, the processor in the first electronic device can instruct the positioning chip to perform positioning and send the first positioning information to the cloud server through the antenna so as to realize positioning.

After the startup state is switched to the shutdown state, the internet of things chip in the first electronic device can instruct the positioning chip to perform positioning, and the positioning information is sent to the cloud server through the antenna, so that positioning is realized.

(2) The positioning system sends the positioning information to the second electronic equipment

A short-range wireless connection, such as a Wi-Fi direct or bluetooth connection, may be established between the first electronic device and the second electronic device. The first electronic device may send positioning information to the second electronic device over the short-range wireless connection.

The cloud server may store an association relationship between the device information of the first electronic device and the first account. The second electronic device can obtain the device information of the first electronic device through the cloud server and establish short-distance wireless connection with the first electronic device.

In response to the user operation, the second electronic device may send an instruction to the first electronic device for obtaining the positioning information through the short-range wireless connection. In the power-on state, in response to the instruction, the processor in the first electronic device obtains the positioning information and sends the positioning information to the second electronic device through the antenna through the short-distance wireless connection. In a power-off state or in a case of poor signal quality of a cellular network, the chip of the internet of things in the first electronic device may obtain the positioning information, and send the positioning information to the second electronic device through the antenna through the short-distance wireless connection.

When the lost first electronic equipment is shut down, the internet of things chip in the first electronic equipment can still be in a working state, real-time positioning information can be obtained from the positioning chip and sent to the cloud server through the antenna, and positioning is achieved. Therefore, the situation that the user cannot obtain the real-time positioning information of the lost equipment when the lost equipment is shut down is reduced, and the convenience of equipment positioning is improved.

In an embodiment of the present application, the processor may obtain the positioning information (e.g., the first positioning information and the second positioning information) from the positioning chip in response to receiving a request (e.g., the second request) for obtaining the positioning information. The processor can also periodically obtain the positioning information from the positioning chip and send the positioning information.

In some embodiments of the present application, after the chip of the internet of things is connected to the battery, the connection between the battery and the processor is still conducted. The processor and the chip of the internet of things can be both in working states. The processor may also enter a sleep state if the connection between the battery and the processor is made and the processor is operating on the sleep clock signal. When user operation for starting up is received, the processor enters a starting up state from a dormant state.

In some embodiments of the present application, after the chip of the internet of things is connected to the battery, the power switch may be controlled by the processor to disconnect the battery from the processor. After the connection between the battery and the processor is broken, the processor may enter a sleep state.

With reference to the first aspect, in some embodiments, the processor is specifically configured to, in response to a user operation for shutdown, perform the following operations: controlling the antenna switch to conduct the connection between the Internet of things chip and the antenna and disconnect the connection between the processor and the antenna; and controlling the chip switch to conduct the connection between the Internet of things chip and the positioning chip and disconnect the connection between the processor and the positioning chip.

With reference to the first aspect, in some embodiments, the internet of things chip is further configured to, in response to a user operation for starting up, control the antenna switch to conduct a connection between the processor and the antenna, and control the chip switch to conduct a connection between the processor and the positioning chip; the positioning chip is used for positioning to obtain third positioning information; the processor is used for obtaining the third positioning information from the positioning chip through the connection with the positioning chip and sending the third positioning information through the connection with the antenna.

In the embodiment of the application, when the lost first electronic device is restarted from a shutdown state, the processor in the positioning system of the first electronic device can be in a working state again, and can obtain real-time positioning information from the positioning chip, and the real-time positioning information is sent to the cloud server through the antenna, so that positioning is realized, and the positioning accuracy and convenience are improved.

With reference to the first aspect, in some embodiments, the processor is further connected to the internet of things chip; the processor is also used for storing the security authentication information of the subscriber identity module SIM, and carrying out authentication according to the security authentication information of the SIM, and accessing the cellular network if the authentication is passed; the cellular network is configured to transmit the first positioning information; the processor is further configured to send the security authentication information of the SIM to the internet of things chip; the Internet of things chip is further used for authenticating according to the safety authentication information of the SIM, the Internet of things network is accessed when the SIM passes the safety authentication information, and the Internet of things network is used for sending the second positioning information.

The chip of the internet of things can be connected with the processor through any one or more of the following interfaces: UART/SPI/I2C/GPIO. When user operation for shutdown is received, the processor can transmit the latest positioning information, the starting file of the positioning chip and the like to the Internet of things chip through the wired connection before dormancy.

Wherein the memory of the processor arrangement can include a security unit therein, which can store eSIM information. The eSIM information can be used to provide operator authentication for the electronic device to access the cellular network, and the electronic device can access the cellular network if the authentication is passed. The chip of the internet of things can acquire the eSIM information stored in the security unit, and the chip of the internet of things can utilize the eSIM information to carry out operator authentication and access a cellular network or a network of the internet of things in a power-off state.

Wherein, the positioning chip can comprise one or more of the following: bluetooth module, GPS, Wi-Fi chip and big dipper location chip. When the first electronic equipment is in a starting state, the Bluetooth, GPS and Wi-Fi chips receive electromagnetic waves through the antenna, frequency modulation and filtering processing are carried out on electromagnetic wave signals, and the processed signals are sent to the processor. When the first electronic device is in a starting state, the Bluetooth, GPS and Wi-Fi chips can also receive a signal to be sent from the processor, perform frequency modulation on the signal, amplify the signal, and convert the signal into electromagnetic wave radiation through the antenna.

With reference to the first aspect, in some embodiments, the internet of things chip includes the following states: a an activated state; b, standby state; c deep sleep state. Wherein:

a activated state

In the activated state, the internet of things chip is specifically configured to periodically obtain the second positioning information from the positioning chip and send the second positioning information to the cloud server. When receiving the first request, the second electronic device may directly obtain the location information of the first electronic device from the cloud server.

b standby state

In the standby state, the internet of things chip is specifically configured to, in response to receiving a request (e.g., a second request) for obtaining positioning information, obtain the second positioning information from the positioning chip and send the second positioning information.

In another embodiment, in the standby state, the internet of things chip may also periodically obtain the second positioning information from the positioning chip and send the second positioning information. The period may be greater than the period for transmitting the positioning information in the active state.

c deep sleep state

Under the deep sleep state, the internet of things chip is specifically used for being in a sleep state. The chip of the internet of things can be in a dormant state under the action of the dormant clock signal. In a deep sleep state, the internet of things chip can be periodically awakened to a working state (a clock signal is switched to a working clock signal), and real-time positioning information is obtained and sent to the cloud server. Or when the Internet of things chip receives the second request, the Internet of things chip wakes up and obtains the positioning information and sends the positioning information to the cloud server.

With reference to the first aspect, in some embodiments, the internet of things chip is further configured to be in the activated state when the remaining battery capacity is greater than or equal to a first set threshold; the Internet of things chip is also used for being in an activated state when the residual electric quantity of the battery is greater than or equal to a first set threshold value; the Internet of things chip is also used for switching the activation state to the standby state when the residual battery capacity is greater than or equal to a second set threshold and smaller than the first set threshold; the internet of things chip is further used for switching from the standby state to the deep sleep state when the remaining battery power is smaller than the second set threshold.

In a possible implementation manner, when the second request is not received, the internet of things chip may be in a standby state or a deep sleep state. For example, the internet of things chip is in a standby state, and if the second request is not received within a first set time, the internet of things chip enters a deep sleep state. When the second request is received through the antenna, the second request is used for obtaining the positioning information of the first electronic device, and the chip of the internet of things can enter an activated state. And when the second request is not received for the second set time, the Internet of things chip can enter a standby state. When the duration of the standby state is longer than or equal to the first set time, the Internet of things chip can enter a deep sleep state.

In the implementation manner, the chip of the internet of things can be in a standby state or a deep sleep state when not receiving the request for acquiring the positioning information, so as to save power consumption. Therefore, the endurance time of the electronic equipment can be prolonged on the premise of not influencing the reporting of the positioning information.

In the embodiment of the application, in order to ensure that sufficient residual capacity is supplied to the internet of things chip, the positioning chip and the antenna, the residual capacity of the battery is set to be 8% for example, which is higher than 3% in a common scene.

In the power-on state, when the signal quality of the cellular network is poor, the first electronic device may send the positioning information through other networks. Therefore, the first electronic equipment can select a network with good signal quality from the cellular network signal, the Internet of things signal, the Beidou positioning signal and the Bluetooth signal and send positioning information.

Specifically, in the power-on state, when the signal quality of the cellular network is good (for example, the signal strength is greater than the first strength threshold), the processor may obtain the positioning information from the positioning chip, and send the positioning information to the cloud server through the cellular network. When the signal intensity of the cellular network signal is detected to be smaller than a first intensity threshold value, under the starting state, the processor can control the power switch to conduct the battery and the Internet of things chip, the antenna switch is controlled to conduct connection between the Internet of things chip and the antenna, the control chip switch conducts connection between the Internet of things chip and the positioning chip, and positioning is achieved through the Internet of things chip by means of the Internet of things network.

Under the power-on state, when cellular network signal and thing networking signal quality are all not good, the treater still can be through the antenna (being big dipper antenna) of being connected with big dipper location chip, with locating information send for cloud ware.

Under the power-on state, when the cellular network signal and the internet of things signal quality are poor, and the Beidou positioning signal quality is also poor, the processor can send the Bluetooth broadcast carrying the positioning information through the Bluetooth module and the antenna, and the equipment, which receives the Bluetooth broadcast, on the periphery of the first electronic equipment sends the positioning information to the cloud server.

In one possible embodiment, the internet of things chip supports a networked network, as well as a cellular network. In the power-off state, when the signal quality of the cellular network is poor, the first electronic device may send the positioning information through other networks. Therefore, in the power-off state, the first electronic equipment can select a network with good signal quality from the cellular network signal, the Internet of things signal, the Beidou positioning signal and the Bluetooth signal and send positioning information.

In this embodiment of the application, when the first electronic device is in a power-off state or the cellular network signal quality is poor, the first electronic device can still obtain the positioning information through the internet of things chip and send the positioning information to the cloud server, and the cloud server sends the positioning information to the second electronic device. Therefore, the situation that the 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.

Referring to fig. 1, fig. 1 is a schematic diagram of a system architecture according to an embodiment of the present disclosure. As shown in fig. 1, specifically, the system includes a lost first electronic device 101, a cloud server 102, and a second electronic device 103. Wherein:

when the lost first electronic device 101 is in the power-on state, the processor in the first electronic device 101 may be in an operating state, and the processor in the first electronic device 101 may communicate with the cloud server 102 through the antenna. In this way, the first electronic device 101 may perform positioning and transmit positioning information to the cloud server 102.

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 may be stored on the cloud server 102. The association relationship may be used for another electronic device (e.g., the second electronic device 103) to acquire the positioning information of the first electronic device 101 from the cloud server 102. The first electronic device 101 can log in the first account.

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, an account "136 ×". The bound cloud server 102 stores the association relationship between the MAC address of the first electronic device 101 and the account number "136 x". The cloud server 102 may further store authentication information (e.g., a login password) corresponding to the account number "136 ×", for authenticating the login request. The first electronic device 101 may log in the first account number "136. Specifically, during the login process, the first electronic device 101 may request the cloud server 102 to log in the first account "136 x", the cloud server 102 may verify the login request of the first electronic device 101, and the first electronic device 101 logs in the first account "136 x" if the verification is passed.

The cloud server 102 may be configured to store an association relationship between the device information of the first electronic device 101 and the first account. The cloud server 102 may also store authentication information for the first account. The cloud server 102 may also obtain location information of the first electronic device 101.

The second electronic device 103 may also log in to the first account. After logging in the first account, the second electronic device 103 may send a request to the cloud server 102 in response to a user operation, where the request is used to obtain the positioning information of the first electronic device 101. The first electronic device 101 may be in a power-on state, and may send the location information of the first electronic device 101 to the cloud server 102. In this way, the cloud server 102 may send, in response to the received request, 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. Thereby, when the first electronic device 101 is lost, the second electronic device 103 obtains the positioning information of the first electronic device 101.

In this embodiment of the application, the first electronic device 101 and the second electronic device 103 may be a mobile phone, an intelligent bracelet, a tablet, an intelligent watch, or the like, which is not limited in this embodiment of the application.

However, when the first electronic device 101 is in the power-off state, the processor in the first electronic device 101 may be in the sleep state, and the processor in the first electronic device 101 cannot obtain the positioning information, and cannot report the positioning information to the cloud server 102. The first electronic device 101 cannot perform positioning after being lost, and cannot send its own positioning information to the cloud server. Thus, it is not beneficial for the user to obtain the location of the first electronic device.

In order to improve the accuracy of positioning, the embodiments of the present application provide a positioning system and a positioning method. The positioning system is used for the first electronic device 101, and includes a processor and an internet of things chip. The processor can be used for obtaining the positioning information from the positioning chip and sending the positioning information to the cloud server through the antenna in the starting state of the first electronic device. When the first electronic device 101 is in the power-off state, the internet of things chip may obtain the positioning information from the positioning chip and send the positioning information to the cloud server through the antenna. In this way, even if the first electronic device is in a power-off state, the positioning information can still be sent to the cloud server to inform the user. Therefore, the situation that the positioning information cannot be obtained after the first electronic equipment is lost is reduced, and the positioning accuracy and convenience are improved.

The positioning system in the embodiment of the application is a chip architecture of a first electronic device including a processor and an internet of things chip.

Specifically, after the processor 302 executes step S110, the internet of things chip 301 may perform operator authentication again according to the eSIM information, and if the authentication is passed, the internet of things chip 301 may establish a connection with the cloud server 102 through the cellular network.

S112, the internet of things chip 301 sends the second positioning information to the cloud server 102 through the antenna.

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

In steps S108 to S113, when the lost first electronic device 101 is turned off, the internet of things chip 301 in the first electronic device 101 may still be in a working state, and may obtain real-time positioning information from the positioning chip, and send the real-time positioning information to the cloud server via the antenna, so as to implement positioning. Therefore, the situation that the user cannot obtain the real-time positioning information of the lost equipment when the lost equipment is shut down is reduced, and the convenience of equipment positioning is improved.

In some embodiments of the present application, after the battery 303 and the internet of things chip 301 are turned on after step S108, the internet of things chip 301 may operate in any one of three modes: active, standby, deep sleep.

In the activation mode, the internet of things chip 301 may periodically obtain the positioning information and send the positioning information to the cloud server 102. The second electronic device 103, upon receiving the first request, may obtain the location information of the first electronic device 101 directly from the cloud server 102. The power consumption is greatest in the active mode compared to the other two modes. In the standby mode, the internet of things chip 301 may still work under the working clock, and the period for sending the positioning information may be increased, or the positioning information may be sent only when the second request is received. The power consumption in the standby mode is less than the active mode and greater than the deep sleep mode. In the deep sleep mode, the internet of things chip 301 may be in a sleep state under the action of the sleep clock signal. The internet of things chip 301 may periodically wake up to a working state (the clock signal is switched to a working clock signal), and obtain real-time positioning information and send the real-time positioning information to the cloud server 102. Or when the Internet of things chip receives the second request, the Internet of things chip wakes up and obtains the positioning information and sends the positioning information to the cloud server. The power consumption in the deep sleep mode is minimal compared to the other two modes.

Specifically, in a possible implementation manner, when the second request is not received, the internet of things chip 301 may be in a standby state or a deep sleep state. For example, first, the internet of things chip 301 is in a standby state, and if the second request is not received within a first set time, the internet of things 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 internet of things chip 301 may enter an active state. When the second request is not received for the second set time, the internet of things chip 301 may enter a standby state. When the duration of the standby state is greater than or equal to a first set time, the internet of things chip 301 may enter a deep sleep state.

In the above implementation manner, when the internet of things chip 301 does not receive the request for obtaining the positioning information, it may be in a standby state or a deep sleep state, so as to save power consumption. Therefore, the endurance time of the electronic equipment can be prolonged on the premise of not influencing the reporting of the positioning information.

In another possible implementation manner, the internet of things chip 301 may further obtain the remaining power of the battery 303, and adjust the operating 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 (e.g., 30% remains), the internet of things chip 301 may be in an active state or a standby state. When detecting that the remaining power is less than the set threshold, the internet of things chip 301 may operate in the deep sleep mode. The setting of one battery remaining capacity threshold is not limited to one, and may be plural. For example, when the remaining power is greater than or equal to a first set threshold (e.g., 50% remaining), the internet of things chip 301 may be in an activated state. When the remaining power is greater than or equal to a second set threshold (for example, 10% remains) and less than the first set threshold, the internet of things chip 301 may switch from the active state to the standby state. When the remaining power is less than the second set threshold, the internet of things chip 301 may be switched from the standby state to the deep sleep state.

In this embodiment, 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. Typically the set threshold is, for example, 3% remaining. In the embodiment of the present application, in order to ensure that sufficient remaining power is supplied to the internet of things chip 301, the positioning chip, and the antenna, the threshold value of the remaining power of the first electronic device 101 is set to be, for example, 8%, which is higher than the above 3%. It should be understood that the above examples of setting the threshold value for the remaining power are only used for explaining the embodiments of the present application, and should not be construed as limiting.

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

In the embodiment of the present application, the execution sequence of steps S114, S115, and S116 is not limited.

S117 and the power switch 1 is controlled by the internet of things chip 301 to disconnect the connection between the battery 303 and the internet of things chip 301.

After the connection between the battery 303 and the internet of things chip 301 is disconnected, the internet of things chip 301 enters a sleep state.

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

S119, the processor 302 sends the 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.

In this embodiment, the third positioning information may be the same as or different from the first positioning information.

In steps S116 to S120, when the lost first electronic device 101 is restarted from the shutdown state, the processor 302 in the first electronic device 101 may be in the working state again, and may obtain real-time positioning information from the positioning chip, and send the real-time positioning information to the cloud server via the antenna, so as to implement positioning.

In some embodiments of the present application, when the first electronic device 101 is powered off from the power-on startup state, the crystal oscillator system in the first electronic device 101 is still in the working state, and provides a clock signal for the internet of things chip 301. In one possible implementation, the crystal oscillator system may provide a clock signal to the internet of things chip 301 in the power-off state and provide a clock signal to the processor 302 in the power-on state. In another possible implementation, in a shutdown state, the internet of things chip 301 may use a set of crystal oscillator system alone. The case that a common crystal oscillator system and the internet of things chip 301 use one crystal oscillator system separately is described below.

Chip 301 and processor 302 of Internet of things share crystal oscillation system

Referring to fig. 5, fig. 5 is a schematic structural diagram of another electronic device 10 according to an embodiment of the present disclosure.

For example, the power chip 307 divides the clock signal with the frequency f1 output by the crystal oscillator 308 to obtain an operating clock signal with the frequency f2 and a sleep clock signal with the frequency f 3. When the electronic device 10 is in a power-off state, the working clock signal and the sleep clock signal are respectively output to the internet of things chip 301. Wherein:

the operating clock signal is used to provide a reference when the chip 301 of the internet of things operates (for example, when the positioning information is transmitted through the antenna), so that the modules operate in a uniform and synchronous manner. The frequency of the operating clock signal is for example 38 MHz.

The sleep clock signal may be continuously output to the internet of things chip 301 or the processor 302 in the power-off state, so as to maintain the continuity of time in the electronic device 10, and also to provide a reference for each module when the working clock signal is not needed.

For example, when the electronic device 10 is in the power-on state, the power chip 307 divides the clock signal with the frequency f1 output by the crystal oscillator 308 to obtain an operating clock signal with the frequency f4 and a sleep clock signal with the frequency f 5.

The following describes the positioning principle under 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 may obtain the positioning information by positioning through the positioning chip. The processor 302 in the first electronic device 101 may select a network with good signal quality (e.g., signal strength greater than a first strength threshold) to transmit the positioning information according to the connection condition of the network signal. When the first electronic device 101 is in the power-off state, the processor 302 is in the sleep state, and the internet of things chip 301 in the first electronic device 101 may also select a network with good signal quality (for example, the signal strength is greater than the first strength threshold value) to send the positioning information according to the connection condition of the network signal. The positioning principle in the power-on state and the power-off state is described below.

Positioning principle in starting-up state

This is described below in conjunction with table 1. Referring to table 1, table 1 is an example of a positioning principle of a first electronic device in a boot-up state according to an embodiment of the present disclosure.

Table 1 is an example of a positioning principle of a first electronic device in a boot-up state according to an embodiment of the present application

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

In scenario 2, the cellular network signal quality is poor (e.g., the signal strength is less than the first strength threshold), the internet of things (IoT) signal quality is good (e.g., the signal strength is greater than the second strength threshold), for example, the user carries the first electronic device 101 in an underground garage, basement, or other place where the cellular network signal quality is poor. When detecting that the signal intensity of the cellular network signal is smaller than the first intensity threshold, in a power-on start state, the processor may control the power switch 1 to conduct the battery 303 and the internet of things chip 301, control the antenna switch to conduct the connection between the internet of things chip and the antenna, and control the chip switch to conduct the connection between the internet of things chip 301 and the positioning chip, which may specifically refer to steps S108 to S110 in the example described with reference to fig. 4. The chip of the internet of things can obtain positioning information through any one or more of the following steps: the GPS positioning/Wi-Fi positioning/bluetooth positioning/beidou positioning, and sends positioning information to the cloud server 102 through the internet of things network.

In scenario 3, the cellular network signal and the internet of things signal are not good in quality. For example, the signal strength of the cellular network signal is less than a first strength threshold, and the signal strength of the internet of things signal is less than a second strength threshold. When the signal intensity of the cellular network signal is detected to be smaller than the first intensity threshold value and the signal intensity of the internet of things signal is detected to be smaller than the second intensity threshold value, the processor can 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 an antenna (i.e., a beidou antenna) connected to the beidou positioning chip 305. The beidou positioning chip 305 and the beidou antenna can refer to the beidou positioning chip 305 and the antenna k +1 in the example described in fig. 7. In scenario 3, the processor may obtain the positioning information through GPS positioning/Wi-Fi positioning/bluetooth positioning instead of obtaining the positioning information through beidou positioning.

In scene 4, the cellular network signal and the internet of things signal are poor in quality, and the Beidou positioning signal is also poor in quality. For example, the signal intensity of the cellular network signal is smaller than a first intensity threshold, the signal intensity of the internet of things signal is smaller than a second intensity threshold, and the signal intensity of the Beidou positioning signal is smaller than a third intensity threshold. When the signal intensity of the cellular network signal is detected to be smaller than the first intensity threshold, the signal intensity of the internet of things signal is detected to be smaller than the second intensity threshold, and the signal intensity of the Beidou positioning signal is detected to be smaller than the third intensity threshold, the processor can obtain positioning information through Bluetooth positioning. When the positioning information is sent, the processor can send the Bluetooth broadcast carrying the positioning information through the Bluetooth module and the antenna, and the equipment, which receives the Bluetooth broadcast, on the periphery of the first electronic equipment sends the positioning information to the cloud server. In scenario 4, the processor may obtain the positioning information through GPS positioning/Wi-Fi positioning/beidou positioning, not limited to obtaining the positioning information through bluetooth positioning.

In the above positioning scheme in the power-on state, when the signal quality of the cellular network is poor, the processor may send the positioning information in other manners. Like this, when first electronic equipment is in the not good environment of cellular network signal quality, perhaps the not good environment of thing networking signal quality, perhaps big dipper positioning signal quality, first electronic equipment homoenergetic enough sends cloud ware with locating information, and the server sends the second electronic equipment and then realizes telling the locating information of first electronic equipment of user. Therefore, the situation that the positioning information cannot be obtained after the first electronic equipment is lost is reduced, and the convenience of positioning is improved.

(II) positioning principle in shutdown state

This is described below in conjunction with table 2. Referring to table 2, table 2 is an example of a positioning principle of the first electronic device in the shutdown state according to the embodiment of the present application.

Table 2 is an example of a positioning principle in a power-off state of a first electronic device according to an embodiment of the present application

Compared with the scenario described in table 1, in table 2, the first electronic device is in a power-off state, the processor in the first electronic device is in a sleep state, and the internet of things chip replaces the processor to obtain the positioning information and send the positioning information through the antenna.

Specifically, in one possible embodiment, the internet of things chip supports an internet of things network, as well as a cellular network. As shown in scenario 5 in table 2, when the signal quality of the cellular network is good (for example, the signal strength is greater than the strength threshold), the internet of things chip may obtain the positioning information from the positioning chip and send the positioning information to the cloud server 102 through the cellular network. The positioning method is any one or more of GPS positioning/Wi-Fi positioning/Bluetooth positioning/Beidou positioning.

In scenario 6, the cellular network signal quality is poor (e.g., the signal strength is less than the first strength threshold), the internet of things signal quality is good (e.g., the signal strength is greater than the second strength threshold), for example, the user carries the first electronic device 101 that is powered off in an underground garage, or other places where the cellular network signal quality is not good. When the signal strength of the cellular network signal is detected to be less than the first strength threshold, the internet of things chip may obtain the positioning information through any one or more of the following: the GPS positioning/Wi-Fi positioning/bluetooth positioning/beidou positioning, and sends positioning information to the cloud server 102 through the internet of things network.

In scenario 7, the cellular network signal and the internet of things signal are not good in quality. For example, the signal strength of the cellular network signal is less than a first strength threshold, and the signal strength of the internet of things signal is less than a second strength threshold. When the signal intensity of the cellular network signal is detected to be smaller than the first intensity threshold value and the signal intensity of the internet of things signal is detected to be smaller than the second intensity threshold value, the internet of things chip can perform Beidou positioning through the Beidou positioning chip 305 to obtain positioning information. The internet of things chip can also send the positioning information to the cloud server 102 through an antenna (i.e., a Beidou antenna) connected with the Beidou positioning chip 305. The beidou positioning chip 305 and the beidou antenna can refer to the beidou positioning chip 305 and the antenna k +1 in the example described in fig. 7. In the scene 7, positioning information is not limited to be obtained through Beidou positioning, and the Internet of things chip can also obtain positioning information through GPS positioning/Wi-Fi positioning/Bluetooth positioning.

In scene 8, the cellular network signal and the internet of things signal are poor in quality, and the Beidou positioning signal is also poor in quality. For example, the signal intensity of the cellular network signal is smaller than a first intensity threshold, the signal intensity of the internet of things signal is smaller than a second intensity threshold, and the signal intensity of the Beidou positioning signal is smaller than a third intensity threshold. When the signal intensity of the cellular network signal is detected to be smaller than the first intensity threshold value, the signal intensity of the internet of things signal is detected to be smaller than the second intensity threshold value, and the signal intensity of the Beidou positioning signal is detected to be smaller than the third intensity threshold value, the internet of things chip can obtain positioning information through Bluetooth positioning. When the positioning information is sent, the Internet of things chip can send the Bluetooth broadcast carrying the positioning information through the Bluetooth module and the antenna, and the equipment, which receives the Bluetooth broadcast, on the periphery of the first electronic equipment sends the positioning information to the cloud server. In the scene 8, positioning information is not limited to be obtained through bluetooth positioning, and the internet of things chip can also obtain the positioning information through GPS positioning/Wi-Fi positioning/Beidou positioning.

In the above positioning scheme in the shutdown state, when the network signal quality is poor, the internet of things chip may send the positioning information in other ways. Like this, not only can realize that first electronic equipment has shut down still can send self locating information, and when the first electronic equipment that has shut down is in the environment that cellular network signal quality is not good, or the environment that thing networking signal quality is not good, perhaps big dipper locating signal quality is not good, first electronic equipment can also send locating information to the cloud ware, and the server sends for second electronic equipment and then realizes telling the locating information of first electronic equipment of user. Therefore, the situation that the positioning information cannot be obtained after the first electronic equipment is lost is reduced, and the convenience of positioning is improved.

In this embodiment, 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, such as a Wi-Fi direct or bluetooth connection, may be established between the first electronic device 101 and the second electronic device 103. The first electronic device 101 may send positioning information to the second electronic device 103 via 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 an association relationship between the device information of the first electronic device 101 and the first account. The second electronic device 103 may obtain device information of the first electronic device 101 through the cloud server 102 and establish a short-range wireless connection with the first electronic device 101. When the user forgets where the first electronic device 101 is located, the find device control may be clicked on the user interface of the second electronic device 103. In response to the user operation, the second electronic device 103 may transmit an instruction for acquiring the positioning information to the first electronic device 101 through the short-range wireless connection. In the power-on state, in response to the instruction, the processor in the first electronic device 101 obtains the positioning information and sends the positioning information to the second electronic device 103 through the short-range wireless connection via the antenna. In the off state or in the case of poor signal quality of the cellular network, the chip of the internet of things in the first electronic device 101 may obtain the 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 the positioning information to the cloud server, where the identifier may indicate whether the first electronic device is currently powered off, the signal quality is good or bad, the power level is low, and the like. The cloud server may also send the identifier to the second electronic device when sending the positioning information to the second electronic device. The second electronic device may display a prompt that may indicate whether the first electronic device is currently powered off, whether the signal quality is good or bad, and so on.

Specifically, please refer to fig. 9A to 9D, and fig. 9A to 9D are schematic diagrams of some user interfaces provided in the embodiments of the present application. As shown in fig. 9A, the second electronic device may display a user interface 100, where the user interface 100 is, for example, a user interface for finding a mobile phone application, and the second electronic device and the first electronic device may both be looking for a mobile phone application and may log in to the first account. As shown in fig. 9A, the user interface 100 may contain device options 1001. The device option 1001 may indicate a 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 a first account, and the cloud server may find device information (for example, device information of the first electronic device) of a device associated with the first account 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 carries, for example, an identifier indicating that the first electronic device is in the on state and the cellular signal quality is good. The indication may also indicate a remaining power of the first electronic device, for example 87%. In response to receiving the positioning information and identification, the second electronic device displays the user interface 200.

As shown in fig. 9B, user interface 200 may include a power prompt 2001, a status prompt 2002, a device location indication 2003, a navigation control 2004, a positioning control 2005, a ring control 2006, a lock control 2007, and a data wipe control 2008. Wherein:

a power prompt 2001 for prompting the current remaining power of the first electronic device, which may be sent from the first electronic device via the cloud server in the identifier, for example, the remaining power is 87%.

And the status prompt 2002 is used for prompting whether the first electronic device is powered on currently or not, and whether the signal quality is good or bad. For example, prompting "device on state and online". Similarly, the status may also be sent from the first electronic device via the cloud server in the identity, e.g., the first electronic device is currently in a powered-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 the positioning information and send the positioning information, the device state, the electric quantity and the like to the cloud server through the antenna. At this time, the internet of things chip in the first electronic device can be in a dormant state.

And a navigation control 2004, configured to navigate according to the positioning information of the first electronic device and the current location information of the second electronic device.

And a positioning control 2005 for retrieving positioning information of the first electronic device.

A ring control 2006 configured to send a ring indication to the first electronic device via the cloud server. In response to a user operation acting on ring control 2006, the second electronic device may send a ring indication to the cloud server, which may forward the ring indication to the first electronic device over the cellular network. The processor in the first electronic device may activate the speaker for ringing based on the ringing indication.

A lock control 2007 to send a lock indication to the first electronic device via the cloud server. In response to a user operation acting on lock control 2007, the second electronic device may send a lock indication to the cloud server, which may forward the lock indication to the first electronic device over the cellular network. The processor in the first electronic device may lock the first electronic device based on the lock indication. After the first electronic equipment is locked, the interface of the application, such as an album application, a payment application and the like, is not displayed any more and is locked and cannot be opened.

And a data erasure control 2008 configured to send a data erasure indication to the first electronic device via the cloud server. In response to a user operation acting on the data wipe control 2008, the second electronic device may send a data wipe indication to the cloud server, which may forward the data wipe indication to the first electronic device over the cellular network. The processor in the first electronic device may delete the private data in the first electronic device according to the data erasure indication. The privacy data includes, for example, image data, account data for application login, 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 send the first request to the cloud server again, and the cloud server may send the second request to the first electronic device again, so as to obtain 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 identification.

For example, if the cellular network signal quality of the first electronic device is poor (e.g., the signal quality is lower than the first strength threshold), the processor in the first electronic device may control the switch to enable the internet of things chip 301 to take over the positioning chip and the antenna. The Internet of things chip can obtain updated positioning information and updated identification and send the updated positioning information and the updated identification to the cloud server. The update identifier indicates that the first electronic device is in a power-on state and the signal quality of the internet of things is good, for example. The indication may also indicate a remaining power of the first electronic device, for example 85%. In response to receiving the updated location information and the updated identification, the second electronic device refreshes the user interface 200.

As shown in fig. 9C, on the refreshed user interface 200, the power supply indication 2001, the status indication 2002, and the device location indication 2003 are updated according to the updated flag. The electric power prompt 2001 may prompt that the remaining electric power is 85%. The status prompt 2002 may indicate "device powered on status and internet of things signal online".

As shown in fig. 9C, in response to a user operation acting on ring control 2006, the second electronic device may send a ring indication to the cloud server, which may forward the ring indication to the first electronic device over the cellular network. The chip of the internet of things in the first electronic device can start the loudspeaker to ring according to the ringing indication. In this application embodiment, the thing networking chip can be connected with the speaker. In another possible implementation, the internet of things chip may notify the processor so that the processor invokes speaker ringing.

Similarly, for the user operation acting on the locking control 2007 and the user operation acting on the data erasing control 2008, the internet of things chip can correspondingly perform locking of the first electronic device and erasing of the private data. In another possible implementation, the chip of the internet of things may notify the processor (e.g., wake up the processor), and the processor performs locking of the first electronic device and erasing of private data.

For example, 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 a first request to the cloud server again, and the cloud server may send a second request to the first electronic device again to obtain updated device information again. After receiving the location information updated again from the first electronic device, the cloud server sends the location information updated again to the second electronic device. The re-updated positioning information carries, for example, a re-updated identification.

For example, if the first electronic device is in a power-off state at this time, the processor in the first electronic device may control the switch to enable the internet of things chip 301 to take over the positioning chip and the antenna. The Internet of things chip can obtain the location information and the identification which are updated again and send the location information and the identification to the cloud server. The re-updating flag indicates that the first electronic device is in a power-off state and the signal quality of the internet of things is good, for example. The re-updated indication may also indicate a remaining power of the first electronic device, for example 84%. In response to receiving the re-updated location 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 after the refresh again, the power supply instruction 2001, the status instruction 2002, and the device location instruction 2003 are updated according to the flag of the refresh again. The power prompt 2001 may prompt that the remaining power is 84%. The status prompt 2002 may indicate "device off status and internet of things on-line".

In the examples shown in fig. 9A to 9D, the first electronic device is in a power-off state or the cellular network signal quality is poor, the first electronic device may obtain the positioning information through the internet of things chip and send the positioning information to the cloud server, and the cloud server sends the positioning information to the second electronic device. Therefore, the situation that the 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.

An example of a positioning method in a power-on state of a first electronic device provided in an embodiment of the present application is described below with reference to a flowchart.
