In the bluetooth mesh network, for a bluetooth mesh device with low power consumption, the bluetooth mesh device is often in a sleep mode and cannot continuously receive messages, and for some practical use scenes, the power consumption is saved by only setting the sleep mode, and the requirement of reducing the power consumption in practical use cannot be met. For example, the battery of the switch device saves power consumption by setting a sleep mode, the service life of the battery is generally about 1-2 years, but the service life of the switch device is longer and generally longer than 2 years, and therefore, if the battery power of the switch device is consumed, the use of the switch device by a user is affected, and therefore the scheme provides the method for reducing the power consumption of the bluetooth mesh device.
The following describes embodiments of the present invention in detail.
Referring to fig. 1, fig. 1 is a schematic flow chart of an apparatus control method according to an embodiment of the present invention, where the apparatus control method is applied to a bluetooth mesh apparatus, the bluetooth mesh apparatus includes a first controller, a power supply module, a first receiver and a first transmitter, the first receiver and the first transmitter are connected to the first controller, the power supply module is connected to the first controller, the first receiver and the first transmitter both correspond to N working frequency bands, N is an integer greater than 1, and the apparatus control method includes:
s101, when the power supply module provides power for the first controller, the first controller controls the first transmitter to transmit BEACON broadcast in a first working frequency band of N working frequency bands, wherein the first working frequency band is any one of the N working frequency bands.
Wherein, the bluetooth mesh device may be any one of the following: a switch device, a bluetooth headset, a door bell, a Wireless Sensor Network (WSN) device, and the like, wherein the switch device may be, for example, a lamp control switch, or a self-timer switch, and the like.
Optionally, the bluetooth mesh device may also be used as a relay device in the bluetooth mesh network, and is configured to forward the received broadcast data to other devices.
In the embodiment of the invention, a first receiver and a first transmitter in the Bluetooth mesh device correspond to N working frequency bands, wherein the Bluetooth mesh device can work in the N working frequency bands simultaneously or in one of the N working frequency bands, and is arranged to transmit BEACON broadcast in the first working frequency band in order to reduce the power consumption of the Bluetooth mesh device.
For example, when the bluetooth mesh device transmits BEACON broadcasts, the first transmitter may transmit BEACON broadcasts at the same time in three broadcast frequency bands 37, 38 and 39, and the first receiver receives broadcast data in the three broadcast frequency bands, so to further reduce power consumption, the first controller controls the first transmitter to transmit BEACON broadcasts in a first operating frequency band of the 3 operating frequency bands, and controls the first receiver to receive broadcast data in the first operating frequency band, so that broadcast data transmitted by a target device can be received more quickly.
S102, after receiving the broadcast data sent by the target device in the first working frequency band, the first receiver executes a control operation corresponding to the broadcast data, or controls the first transmitter to forward the broadcast data to the first device, and instructs the first device to send the broadcast data to a preset receiving device.
The target device may be a controlled device or a relay device in the bluetooth mesh network, which is adjacent to the bluetooth mesh device, and the target device may be, for example, a lighting device, a mobile phone, or the like.
In the embodiment of the invention, after the first controller of the Bluetooth mesh equipment controls the first transmitter to transmit the BEACON broadcast in the first working frequency band of the N working frequency bands, the target equipment can scan, and if the target equipment receives the BEACON broadcast transmitted by the Bluetooth mesh equipment, Bluetooth communication connection with the Bluetooth mesh equipment can be established. When the first receiver receives broadcast data sent by the target device in the first working frequency band, the control operation corresponding to the broadcast data can be executed, for example, when the target device is a mobile phone and the control device is a micro-power consumption bluetooth mesh remote controller, when the bluetooth mesh remote controller sends broadcast data used for indicating the mobile phone to change music, the mobile phone receives the mesh broadcast data and then performs music changing operation. For another example, the bluetooth mesh device may serve as a relay device in the bluetooth mesh network, and thus, the first transmitter may be controlled to forward the received broadcast data to the first device, and then the first device transmits the broadcast data to the preset receiving device.
For example, when the bluetooth mesh device is a switch device, a piezoelectric or magnetomotive battery-less switch device generally generates 60uJ-600uJ of energy every time the switch device is pressed, the switch device generates energy, and a power circuit of the switch device is generally unpowered and does not work in a non-powered state. When the switch device is pressed, the generated electric energy cannot provide enough energy to enable the switch device to transmit complete and effective broadcast data, the electric energy generated when the switch device is pressed once can only provide and transmit 1 packet of data, if the switch device simultaneously transmits BEACON broadcasts in N working frequency bands, after the switch device transmits the BEACON broadcast in one working frequency band, if the target device scans other frequency bands, the target device may not wait to receive the BEACON broadcast transmitted by the switch device, and the switch device already consumes all the electric energy generated when the switch device is pressed. Therefore, according to the scheme, the first controller controls the first transmitter to transmit the BEACON broadcast in the first working frequency band of the N working frequency bands, and the target device receives the BEACON broadcast in the first working frequency band, so that the scanning switching time of the target device can be reduced, the packet loss rate of data transmission between the switch device and the target device can be reduced, and the success rate of data transmission between the switch device and the target device can be improved.
It can be seen that, in the device control method described in the embodiment of the present invention, the first controller controls the first transmitter to transmit BEACON broadcast in a first operating frequency band of the N operating frequency bands, where the first operating frequency band is any one of the N operating frequency bands; after the first receiver receives the broadcast data sent by the target device in the first working frequency band, the control operation corresponding to the broadcast data is executed, or the first transmitter is controlled to transmit the broadcast data to the first device, and the first device is instructed to send the broadcast data to the preset receiving device.
In one possible example, the bluetooth mesh device is a switch device, and the method may further include the steps of:
s103, when the fact that the number of times that the switch device is pressed within a preset time period is larger than or equal to two times is detected, after the first transmitter transmits BEACON broadcasts for N times in the first working frequency band, controlling the first transmitter to simultaneously transmit the BEACON broadcasts in the N working frequency bands; controlling the first receiver to simultaneously receive broadcast data in the N operating frequency bands;
s104, if the first receiver receives broadcast data of a second working frequency band, controlling the first transmitter to transmit a confirmation message to the target device in the second working frequency band, wherein the second working frequency band is different from the first working frequency band in the N working frequency bands;
and S105, if the first receiver receives the feedback message sent by the target device in the second working frequency band, controlling the first transmitter to perform mesh data communication with the target device in the second working frequency band.
If the switch device is pressed for the first time, the broadcast data is not successfully transmitted to the target device, for example, if the target device is a lamp, the user presses the switch device in sequence, then the lamp is not lighted, and usually presses the switch device once again, because the time interval between the previous 2 times and the next 2 times that the switch device is pressed is short, the switch device still has power, at this time, if the switch device detects that the switch device is pressed for more than two times, the switch device can determine that the broadcast data is not transmitted to the target device, and then, after the first transmitter transmits the BEACON broadcasts for N times in the first working frequency band, the first transmitter can be controlled to simultaneously transmit the BEACON broadcasts in the N working frequency bands, and the first receiver can be controlled to simultaneously receive the broadcast data in the N working frequency bands, if the first receiver receives the broadcast data in the second working frequency band, the first transmitter can be controlled to transmit the confirmation message to the target device in the second working frequency band, if the first receiver receives the feedback message sent by the target device in the second working frequency band, the first transmitter can be controlled to carry out mesh data communication with the target device in the second working frequency band, so that the switch device can be switched to the second working frequency band, and broadcast data can be continuously sent and received in a single frequency band. The energy required for sending broadcast data once in a single working frequency band is about 6uJ, under the condition of piezoelectric power generation, about 5-8 times of data broadcasting can be sent, and under the condition of magnetic kinetic energy, the data broadcasting can be sent to 20-30 times, so that if the switch equipment repeatedly sends data broadcasting for many times, the target equipment can receive the broadcast data sent by the switch equipment if the target equipment scans in the same single working frequency band.
Therefore, the power consumption of the switch device can be reduced by sending and receiving the broadcast data in a single working frequency band, and the reliability and the success rate of data receiving and sending of the switch device can be improved by increasing the broadcasting times and flexibly adjusting the working frequency band for communication of the switch device after multiple times of pressing is detected.
In one possible example, the power module includes a battery and a power circuit, the power circuit includes a power switch, the battery is connected with the first controller through the power circuit, the method further includes:
turning on the power switch to turn on the battery and the first controller when the switching device is pressed;
turning off the power switch after the first controller controls the first transmitter to transmit the BEACON broadcast in a first operating frequency band of the N operating frequency bands.
The first controller is connected with the battery through the power circuit, when the switch equipment is pressed, the power switch is turned on, the power circuit between the battery and the first controller is conducted, and after the first controller of the switch equipment controls the first transmitter to finish sending the BEACON broadcast, the first controller turns off the power switch and cuts off the power supply.
In one possible example, the power module includes an energy harvesting circuit, the method further comprising:
when the switch device is pressed, the energy acquisition circuit acquires energy, and when the energy acquired by the energy acquisition circuit exceeds a preset energy threshold, the first controller controls the first transmitter to transmit BEACON broadcast in a first working frequency band of the N working frequency bands.
The switch device may be a battery-less switch device, the switch device may include an energy collection circuit, the energy collection circuit may store electric energy in the capacitor, the energy collection circuit outputs the electric energy when the electric energy provides broadcast data, and the first controller controls the first transmitter to transmit BEACON broadcast in a first operating frequency band of the N operating frequency bands until the energy is completely consumed.
Therefore, the power consumption of the switch device can be reduced by sending and receiving the broadcast data in a single working frequency band, the electric energy is provided for the switch device through the energy acquisition circuit, the switch device can send the broadcast data to the target device, and the communication success rate between the low-power-consumption switch device and the target device can be improved.

s201, the second receiver receives broadcast data by using a first working frequency band in the N working frequency bands, wherein the first working frequency band is any one of the N working frequency bands.
The target device may be a controlled device or a relay device in the bluetooth mesh network, which is adjacent to the bluetooth mesh device, and the target device may be, for example, a lighting device, a mobile phone, or the like.
In the embodiment of the invention, the second receiver and the first transmitter in the target device correspond to N working frequency bands, and in order to reduce the power consumption of the Bluetooth mesh device, the target device transmits and receives broadcast data in the first working frequency band.
S202, after the second receiver receives BEACON broadcast sent by the bluetooth mesh device in the first working frequency band, the second transmitter sends broadcast data to the bluetooth mesh device in the first working frequency band.
Wherein, the bluetooth mesh device may be any one of the following: a switch device, a bluetooth headset, a door bell, a Wireless Sensor Network (WSN) device, and the like, wherein the switch device may be, for example, a lamp control switch, or a self-timer switch, and the like.
After receiving the BEACON broadcast transmitted by the bluetooth mesh device in the first working frequency band, the target device can transmit broadcast data to the bluetooth mesh device in the first working frequency band, so that bluetooth communication between the bluetooth mesh device and the target device is realized.
It can be seen that, in the device control method described in the embodiment of the present invention, broadcast data is received by the second receiver in a first operating frequency band of the N operating frequency bands, where the first operating frequency band is any one of the N operating frequency bands; after receiving the BEACON broadcast transmitted by the bluetooth mesh device in the first working frequency band, the second transmitter transmits broadcast data to the bluetooth mesh device in the first working frequency band, and compared with the method of continuously receiving and transmitting the broadcast in N working frequency bands at the same time, the scheme only transmits and receives the broadcast in the first working frequency band, so that the power consumption of the target device can be reduced, and the success rate of data transmission from the target device to the target device is improved.
In one possible example, the method further comprises:
and after receiving the broadcast data sent by the Bluetooth mesh device in the first working frequency band, executing control operation corresponding to the broadcast data, or forwarding the broadcast data to a second device.

For another example, the bluetooth mesh device may be a bluetooth selfie stick, and may transmit broadcast data indicating photographing to a target device (mobile phone), so that the target device may perform a photographing operation after receiving the broadcast data.
