Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention discloses a method and a system for reducing power consumption of equipment, wherein first equipment is provided with a first UWB component and a first BLE component, second equipment is provided with a second UWB component and a second BLE component, the first equipment serving as an active interaction end broadcasts an equipment searching request in a preset range based on the first BLE component, when the second equipment receives the equipment searching request, the second equipment feeds back response information supporting UWB communication to the first equipment based on the second BLE component, the first equipment sends a connection request for establishing UWB communication to the second equipment based on the first BLE component, so that the second equipment utilizes the second BLE component to open the second UWB component based on the UWB connection request, and meanwhile, the first equipment opens the first UWB component based on the first BLE component and establishes communication connection with the second UWB component based on the first UWB component. According to the invention, the first device and the second device communicate by using the low-power-consumption BLE component in a normal state so as to achieve the purpose of reducing the power consumption of the devices, and when the first device and the second device need to establish UWB communication connection so as to carry out high-precision positioning, the low-power-consumption BLE component starts the high-power-consumption UWB component so as to meet the requirements of a user on the real-time performance and the high reliability of the devices.
Referring to fig. 2, a flowchart of a method for reducing power consumption of a device is disclosed in an embodiment of the present invention, and the method is applied to a first device serving as an active interactive peer, where the first device has a first UWB (ULTRA WIDE BAND) component and a first BLE (Bluetooth Low Energy) component, and the method includes:
step S101, broadcasting a device searching request in a preset range based on the first BLE component;
wherein the device lookup request is for looking up a second device having a second UWB component and a second BLE component. In this embodiment, the second device serves as a passive interaction terminal.
The UWB is a full name of ultra wide band, and is a wireless carrier communication technology, which uses nanosecond-level non-sinusoidal wave narrow pulses to transmit data, so that the occupied frequency spectrum range is wide. UWB technology has significant advantages in a range of aspects including positioning accuracy, security, penetration, interference immunity, transmission distance, and the like.
BLE aims to significantly reduce power consumption and cost while maintaining equivalent communication range compared to classical bluetooth.
In this embodiment, a first device is used as an active interaction end, a second device is used as a passive interaction end, the first device establishes communication first based on a first BLE component with low power consumption, and broadcasts to inquire whether a second device which supports a UWB function (i.e., has a second UWB component) and has a second BLE component exists nearby, when a distance between the first device and the second device is within a communication range of the BLE component, the first device actively searches for a device search request of a device B, that is, broadcast information is sent to the second device, and the second device can interact with the first device after receiving the device search request.
In practical application, devices insensitive to power consumption, such as a mobile phone, a tablet and the like, can be used as an active interaction end; a device that will be sensitive to power consumption, such as an intelligent refrigerator with BLE and UWB components.
Step S102, receiving response information supporting UWB communication, which is fed back by the second device based on the second BLE component;
after the second device receives the device search request broadcast by the first device, the second device first communicates with the first device based on the second BLE component with lower power consumption, and feeds back response information supporting UWB communication to the first device.
It should be noted that when the second device supports UWB communication, it indicates that the second device can achieve high-precision positioning using the second UWB component provided.
Step S103 of sending a connection request for establishing UWB communication to the second device based on the first BLE component, and enabling the second device to turn on the second UWB component by using the second BLE component based on the connection request;
in this embodiment, after the second device receives the connection request for establishing UWB communication sent by the first device, the second device may turn on the second UWB component through the second BLE component, so that the second device establishes UWB communication with the first UWB component of the first device through the second UWB component.
Step S104, starting the first UWB component based on the first BLE component, and establishing UWB communication connection with the second UWB component based on the first UWB component.
After the first device sends a connection request for establishing UWB communication to the second device, the first device may also turn on the first UWB component through its own first BLE component, so that the first device establishes UWB communication with the second UWB component of the second device through the first UWB component.
In summary, the invention discloses a method for reducing power consumption of a device, wherein a first device is provided with a first UWB component and a first BLE component, a second device is provided with a second UWB component and a second BLE component, the first device serving as an active interaction end broadcasts a device search request within a preset range based on the first BLE component, when the second device receives the device search request, the second device feeds back response information supporting UWB communication to the first device based on the second BLE component, the first device sends a connection request for establishing UWB communication to the second device based on the first BLE component, so that the second device utilizes the second BLE component to open the second UWB component based on the UWB connection request, and meanwhile, the first device opens the first UWB component based on the first BLE component and establishes UWB communication connection with the second BLE component based on the first component. According to the invention, the first device and the second device communicate by using the low-power-consumption BLE component in a normal state so as to achieve the purpose of reducing the power consumption of the devices, and when the first device and the second device need to establish UWB communication connection so as to carry out high-precision positioning, the low-power-consumption BLE component starts the high-power-consumption UWB component so as to meet the requirements of a user on the real-time performance and the high reliability of the devices.
In addition, according to the invention, the UWB component is automatically started through the BLE component without manually opening the UWB component with high power consumption, so that the user experience is improved to a certain extent.
It should be noted that, when the first device needs to establish the UWB communication connection with the second device, the first device needs to obtain permission of the second device and receive the communication key of the second device, so that the UWB communication connection can be established with the second device.
Therefore, to further optimize the above embodiment, step S103 may specifically include:
transmitting a connection request for establishing UWB communication to the second device;
and receiving a communication key fed back by the second equipment after receiving the connection request.
Wherein the second device turns on the second UWB component using the second BLE component after feeding back the communication key.
The communication key has relevant information for establishing the UWB communication connection.
It should be noted that, under normal conditions, the second BLE component of the second device is turned on, and the second UWB component is turned off, so as to reduce energy consumption, and when the second device needs to establish a UWB communication connection with the first device, the second device may turn on the second UWB component through the second BLE component.
To further optimize the above embodiment, step S104 may specifically include:
turning on the first UWB component based on the first BLE component;
establishing a UWB communication connection with the second UWB component through the first UWB component based on the communication key.
When the first device receives the communication key fed back by the second device, the first device indicates that the second device allows the UWB communication connection to be established with the first device. Under normal conditions, a first BLE component of the first device is turned on, and a first UWB component is turned off so as to reduce energy consumption, and when the first device needs to establish UWB communication connection with the second device, the first device can turn on the first UWB component through the first BLE component.
Because the UWB component is higher than the energy consumption of the BLE component, when the first device establishes the UWB communication connection with the second device, if both the first BLE component and the first UWB component of the first device are turned on, a large energy consumption is inevitably caused; similarly, if the second BLE component and the second UWB component of the second device are both turned on, a large energy consumption is inevitably caused.
In order to reduce energy consumption when the first device and the second device are in UWB communication connection, the invention turns off the first BLE component after the first UWB component is turned on, and similarly turns off the second BLE component after the second UWB component is turned on.
Therefore, to further optimize the above embodiment, referring to fig. 3, another method for reducing power consumption of a device disclosed in the embodiment of the present invention is applied to a first device as an active interactive end, and on the basis of the embodiment shown in fig. 2, after step S104, the method may further include:
step S105, sending a BLE turn-off command to the second device based on the first BLE component, so that the second device turns off the second BLE component after receiving the BLE turn-off command;
and S106, turning off the first BLE assembly after the BLE turning-off instruction is sent.
In this embodiment, when the first device and the second device have just started to establish a UWB communication connection, both the first BLE component and the first UWB component of the first device are in an on state, and likewise, both the second BLE component and the second UWB component of the second device are in an on state. In order to reduce the power consumption of the device, the first device sends a BLE closing instruction to the second device, so that the second device closes the second BLE component, and meanwhile, after the first device sends the BLE closing instruction to the second device, the first device also closes the first BLE component of the first device.
After the first device and the second device establish the UWB communication connection through the shared communication key, the first device and the second device may acquire high-precision positioning information from each other.
Therefore, to further optimize the above embodiment, after step S106, the method may further include:
s107, controlling a first UWB component to start a high-precision positioning function, and acquiring first high-precision positioning information of the first equipment relative to the second equipment based on the first UWB component;
step S108, sending the first high-precision positioning information to the second equipment, and acquiring second high-precision positioning information sent by the second equipment;
and the second high-precision positioning information is the high-precision positioning information of the second equipment relative to the first equipment, which is acquired by the second UWB component after the second equipment controls the second UWB component to start the high-precision positioning function.
In this embodiment, after the high-precision positioning information interaction between the first device and the second device is completed, the first device or the second device may initiate to turn off the UWB communication function, and the communication between the first device and the second device is switched from the UWB communication to BLE communication again.
Therefore, to further optimize the above embodiment, after step S108, the method may further include:
step S109, sending a UWB shutdown instruction and a BLE startup instruction to the second device based on the first UWB component, so that the second device shuts down the second UWB component and turns on the second BLE component after receiving the UWB shutdown instruction and the BLE startup instruction;
step S110, after the UWB shutdown instruction and the BLE startup instruction are sent, the first UWB component is shut down, and the first BLE component is turned on.
In the invention, when the first device and the second device need to perform high-precision positioning again, preliminary judgment and preparation can still be realized through low-power-consumption BLE communication.
It should be particularly noted that the communication means between the first device and the second device includes a wire, which is not limited to BLE communication and UWB communication.
Corresponding to the embodiment of the method, the invention also discloses a system for reducing the power consumption of the equipment.
Referring to fig. 4, a schematic structural diagram of a system for reducing power consumption of a device according to an embodiment of the present invention is applied to a first device serving as an active interaction end, where the first device has a first UWB component and a first BLE component, and the system includes:
a broadcasting unit 201, configured to broadcast a device finding request within a preset range based on the first BLE component, where the device finding request is used to find a second device having a second UWB component and a second BLE component;
in this embodiment, a first device is used as an active interaction end, a second device is used as a passive interaction end, the first device establishes communication first based on a first BLE component with low power consumption, and broadcasts to inquire whether a second device which supports a UWB function (i.e., has a second UWB component) and has a second BLE component exists nearby, when a distance between the first device and the second device is within a communication range of the BLE component, the first device actively searches for a device search request of a device B, that is, broadcast information is sent to the second device, and the second device can interact with the first device after receiving the device search request.

It should be noted that, under normal conditions, the second BLE component of the second device is turned on, and the second UWB component is turned off, so as to reduce energy consumption, and when the second device needs to establish a UWB communication connection with the first device, the second device may turn on the second UWB component through the second BLE component.
To further optimize the above embodiment, the connection establishing unit 204 is specifically configured to:
turning on the first UWB component based on the first BLE component;
establishing a UWB communication connection with the second UWB component through the first UWB component based on the communication key.
When the first device receives the communication key fed back by the second device, the first device indicates that the second device allows the UWB communication connection to be established with the first device. Under normal conditions, a first BLE component of the first device is turned on, and a first UWB component is turned off so as to reduce energy consumption, and when the first device needs to establish UWB communication connection with the second device, the first device can turn on the first UWB component through the first BLE component.
Because the UWB component is higher than the energy consumption of the BLE component, when the first device establishes the UWB communication connection with the second device, if both the first BLE component and the first UWB component of the first device are turned on, a large energy consumption is inevitably caused; similarly, if the second BLE component and the second UWB component of the second device are both turned on, a large energy consumption is inevitably caused.
In order to reduce energy consumption when the first device and the second device are in UWB communication connection, the invention turns off the first BLE component after the first UWB component is turned on, and similarly turns off the second BLE component after the second UWB component is turned on.
Therefore, to further optimize the above embodiment, referring to fig. 5, a schematic structural diagram of a system for reducing power consumption of a device according to another embodiment of the present invention is disclosed, where the system is applied to a first device serving as an active interactive end, and on the basis of the embodiment shown in fig. 4, the system may further include:
a first instruction sending unit 205, configured to, after the connection establishing unit 204 turns on the first UWB component based on the first BLE component and establishes a UWB communication connection between the first UWB component and the second UWB component, send a BLE turn-off instruction to the second device based on the first BLE component, so that the second device turns off the second BLE component after receiving the BLE turn-off instruction;
a BLE component turning off unit 206, configured to turn off the first BLE component after sending the BLE turning off command.
In this embodiment, when the first device and the second device have just started to establish a UWB communication connection, both the first BLE component and the first UWB component of the first device are in an on state, and likewise, both the second BLE component and the second UWB component of the second device are in an on state. In order to reduce the power consumption of the device, the first device sends a BLE closing instruction to the second device, so that the second device closes the second BLE component, and meanwhile, after the first device sends the BLE closing instruction to the second device, the first device also closes the first BLE component of the first device.
After the first device and the second device establish the UWB communication connection through the shared communication key, the first device and the second device may acquire high-precision positioning information from each other.
Therefore, to further optimize the above embodiment, the system may further include:
a positioning unit 207, configured to control the first UWB component to turn on a high-precision positioning function after the BLE component turning off unit 206 turns off the first BLE component after sending the BLE turning off instruction, and acquire first high-precision positioning information of the first device relative to the second device based on the first UWB component;
a positioning information sending unit 208, configured to send the first high-precision positioning information to the second device, and obtain second high-precision positioning information sent by the second device;
and the second high-precision positioning information is the high-precision positioning information of the second equipment relative to the first equipment, which is acquired by the second UWB component after the second equipment controls the second UWB component to start the high-precision positioning function.
In this embodiment, after the high-precision positioning information interaction between the first device and the second device is completed, the first device or the second device may initiate to turn off the UWB communication function, and the communication between the first device and the second device is switched from the UWB communication to BLE communication again.
Therefore, to further optimize the above embodiment, the system may further include:
a second instruction sending unit 209, configured to, after the positioning information sending unit 208 sends the first high-precision positioning information to the second device and acquires second high-precision positioning information sent by the second device, send a UWB turn-off instruction and a BLE turn-on instruction to the second device based on the first UWB component, so that the second device turns off the second UWB component and turns on the second BLE component after receiving the UWB turn-off instruction and the BLE turn-on instruction;
a BLE component turning-on unit 210, configured to turn off the first UWB component and turn on the first BLE component after sending the UWB turn-off instruction and the BLE turn-on instruction.
In the invention, when the first device and the second device need to perform high-precision positioning again, preliminary judgment and preparation can still be realized through low-power-consumption BLE communication.
It should be particularly noted that the communication means between the first device and the second device includes a wire, which is not limited to BLE communication and UWB communication.
Finally, it should also be noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions.
