A detailed flowchart of the control method of the electronic device is shown in fig. 5.
Step 101, determining whether a low power consumption switching command is detected. If yes, go to step 102; if not, the process is ended directly.
Specifically, when the electronic device only needs to transmit a small amount of information and the frequency requirement for transmitting information is low, it may be determined that the low power switching command is detected, or the mode controller may be a power detection device that determines that the low power switching command is detected when the power detection device detects that the electronic device is in a low power state.
Specifically, when it is determined that the low power consumption switching command is detected, a start instruction is received, and a low power consumption timer is started.
And step 103, the low-power-consumption timer closes the plurality of high-power-consumption devices and starts to time.
Specifically, after the low-power-consumption timer is started, the electronic device ends a normal working state, enters an ultra-low-power-consumption working mode, the low-power-consumption timer controls to close a plurality of high-power devices to reduce power consumption, so that the electronic device is maintained for a longer time, and then the low-power-consumption timer starts to time.
And step 104, judging whether to count to a preset period.
Specifically, whether a preset period is timed or not is judged, if yes, the step 105 is executed, and a plurality of high-power-consumption devices are awakened; if not, continuing to judge until reaching the preset period.
It should be noted that the preset period should be much longer than the normal broadcast period of the electronic device, so as to achieve low power consumption and inform the functions of other devices, generally in the order of seconds.
And 105, awakening a plurality of high-power-consumption devices in the plurality of high-power-consumption devices by the low-power-consumption timer to send a preset signal.
Specifically, when the electronic device only needs to transmit a small amount of information and the frequency requirement for transmitting the information is low, the preset signal transmitter transmits a preset signal (the preset signal may be short data customized by a user) when the low-power-consumption timer counts to a predetermined period. When the mode controller 3 is an electric quantity detection device, and the electric quantity detection device detects that the electronic equipment is in a low electric quantity state, in order to enable the electronic equipment to be timely discovered by the main equipment for processing, the slave equipment (the electronic equipment) needs to inform the main equipment at regular time, so that the stability of the system is maintained; that is, when the low power consumption timer counts the time to the predetermined period, the preset signal transmitter transmits a preset signal, and the preset signal is a warning signal representing low power. The sending of the preset signal requires the support of several high power consuming devices. Therefore, the low power timer needs to wake up several high power devices.
In practice, referring to fig. 6, in step 105, the low power consumption timer wakes up a plurality of high power consumption devices in the plurality of high power consumption devices to send the preset signal, which specifically includes:
in the substep 1051, after the low power consumption timer wakes up the plurality of high power consumption devices, the high frequency clock generator outputs a high frequency clock signal to the preset signal transmitter.
Specifically, the preset signal transmitter needs timing control of a high-frequency clock signal to send out the preset signal, and therefore, the plurality of high-power-consumption devices at least comprise a high-frequency clock generator; and waking up the high-frequency clock generator, and outputting a high-frequency clock signal to a preset signal transmitter by the high-frequency clock generator.
And a substep 1052, wherein the preset signal transmitter transmits the preset signal under timing control of the high frequency clock signal.
Specifically, the preset signal transmitter generates and transmits the preset signal when receiving the high-frequency clock signal.
And a substep 1053, wherein the preset signal transmitter notifies the low power consumption timer after the preset signal is transmitted.
Specifically, after the preset signal is sent, the preset signal transmitter generates a signal representing that the sending is finished to the low-power-consumption timer; and when the low-power-consumption timer receives the signal, the high-power-consumption devices are closed.
As an example, the predetermined signal may be a bluetooth signal. The length of the preset signal is less than the length of the broadcast signal set in the low-power-consumption Bluetooth protocol, and the preset period is greater than the broadcast interval set in the low-power-consumption Bluetooth protocol. In this embodiment, the preset signal in a proprietary form is set to reduce power consumption as much as possible, ensure that the device can maintain the existing working state for a longer time, and reduce direct mutual interference between the preset signal and other devices.
Wherein, the channel for transmitting the preset signal needs to be in the broadcast channel specified by the low power consumption Bluetooth protocol, so that the channel can be more easily scanned and discovered.
And step 106, turning off a plurality of high-power-consumption devices by the low-power-consumption timer, and restarting timing.
Specifically, after the preset signal is sent, the electronic device enters the ultra-low power consumption mode again, turns off the plurality of high power consumption devices, starts timing again, and enters step 104, determines whether the timing is up to the preset period, and sends the preset signal again when the timing is up to the preset period.
It should be noted that, in this embodiment, the low power consumption timer is started, the low power consumption timer controls to close the plurality of high power consumption devices, and the preset signal is sent by the preset signal transmitter only when the low power consumption timer counts a preset period, but the present invention is not limited to this.
It should be understood that the present embodiment is a method embodiment corresponding to the first embodiment and the second embodiment, and the present embodiment can be implemented in cooperation with the first embodiment and the second embodiment.
