Detailed Description

The invention will be described in detail hereinafter with reference to the drawings in conjunction with embodiments. It should be noted that, in the case of no conflict, the embodiments and features in the embodiments may be combined with each other.

As described in the background art, one important performance index of electronic devices is energy saving and power saving, and long endurance time. However, for some electronic devices, especially for some mobile electronic devices, the problems of high power consumption and insufficient endurance are always difficult to solve, and in terms of hardware, the vibration wake-up circuit in the electronic device usually consumes more power consumption of the electronic device due to the continuous operation characteristic and the uncertain factor of the pin state of the vibration sensor, so that the endurance of the electronic device is reduced.

In the prior art, the vibration sensor is generally used as a vibration sensing circuit connected to a vibration wake-up pin of the control circuit, and the vibration wake-up circuit can realize the vibration wake-up function of the electronic device, but the characteristics of the vibration sensor can make the vibration wake-up circuit easily consume more power consumption. For example, with a conventional switch-type vibration sensor, for example, when vibration occurs, two pins of the vibration sensor are rapidly switched between on and off states; at rest, the two pins of the vibration sensor are randomly in a connected state or in a disconnected state. If the two pins are in exactly communication when the vibration sensor is in a stationary state, a significant amount of power consumption is consumed. For example, as shown in fig. 1, taking the supply voltage value Vcc in the circuit as 3.3V and taking the pull-down resistor inside the control circuit in the circuit as 40kΩ, when the vibration sensor is in a stationary state and the two pins are just in a connected state, the power consumption of the vibration wake-up circuit will reach 3.3V/40kΩ=82.5 uA, which will be a very high power consumption value.

In response to the above-described problems, in one embodiment, as shown in fig. 2, a shock wake-up circuit is provided, which may be connected to a shock wake-up pin of a control circuit and output a shock wake-up signal to the control circuit through the shock wake-up pin. Specifically, the vibration wake-up circuit can include a vibration sensing circuit, a signal isolation circuit and a switch circuit, wherein the vibration sensing circuit is connected with the input end of the signal isolation circuit, the output end of the signal isolation circuit is connected with the control end of the switch circuit, and the output end of the switch circuit is connected with the vibration wake-up pin of the control circuit. When the vibration sensing circuit collects vibration signals (namely, when the vibration sensor senses the movement of the electronic equipment), the signal isolation circuit can transmit the vibration signals to the switch circuit and conduct the switch circuit, so that the switch circuit can output vibration wake-up signals (the vibration wake-up signals can be represented by high and low level signals) and are received by the vibration wake-up pins of the control circuit. Further, when the control circuit is in the sleep mode and enables the vibration wake-up function, the control circuit responds to the vibration wake-up signal input by the vibration wake-up pin and switches from the sleep mode to the working mode; when the control circuit is in the working mode or the control circuit is in the sleep mode but the vibration wake-up function is closed, the control circuit does not respond to the vibration wake-up signal input by the vibration wake-up pin. However, no matter what mode the control circuit is in, the vibration wake-up circuit can convert the collected vibration signal into the vibration wake-up signal and output the vibration wake-up signal to the control circuit, so that the vibration wake-up circuit has the characteristic of continuous operation, and the reduction of the electric quantity consumption of the vibration wake-up circuit becomes a key factor for improving the endurance time of the electronic equipment.

The vibration wake-up circuit converts the vibration signal into the vibration wake-up signal through the signal transmission mode and outputs the vibration wake-up signal to the control circuit, so that the signal output is more accurate and stable, and the power consumption waste caused by response errors of the control circuit is avoided.

In an alternative embodiment, as shown in fig. 3, the vibration sensing circuit includes a vibration sensor, a first pull-up resistor R1 and a first current limiting resistor R5, where one end of the vibration sensor is connected to the ground through the first current limiting resistor R5, the other end of the vibration sensor is connected to the power supply through the first pull-up resistor R1, and the end of the vibration sensor connected to the first pull-up resistor R1 is further connected to the input end of the signal isolation circuit. In this embodiment, the first current limiting resistor R5 can prevent the excessive current generated by the signal isolation circuit during discharge from wearing the vibration sensor.

In the above embodiment, when the electronic device moves, the vibration sensor receives the oscillating signal that changes continuously, and then the vibration sensing circuit follows the level signal of the output oscillation. Specifically, when the vibration sensor does not receive the oscillation signal, the voltage value at the point a in fig. 3 will remain constant; when the vibration sensor receives the oscillation signal, the voltage value at the point a in fig. 3 also oscillates, and in this way, the vibration sensing circuit can convert the received oscillation signal into an oscillating voltage signal and transmit the oscillating voltage signal to the signal isolation circuit.

In the above embodiment, the first pull-up resistor R1 and the first current limiting resistor R5 may also limit the power consumption value of the shock sensing circuit to a very small range. For example, as shown in fig. 3, taking the supply voltage Vcc of 3.3V, taking the first pull-up resistor R1 of 1mΩ and the first current limiting resistor R5 of 10kΩ, when the vibration sensor is in a stationary state and the two pins are just in a connected state, the power consumption of the vibration wake-up circuit is 3.3V/(1mΩ+10kΩ) ≡3.3uA; when the vibration sensor is in a static state and the two pins are just in a disconnected state, no current flows through the vibration sensor, and the power consumption of the vibration wake-up circuit is zero. According to the embodiment, no matter what state the vibration sensor is in, the current value is far smaller than the current value when the vibration sensor is directly connected to the control circuit, so that the power consumption of the electronic equipment can be effectively reduced, and the cruising ability of the electronic equipment is improved.

In an alternative embodiment, as shown in fig. 3, the shock sensor may be a shock switch. In particular, there are various structures of the shock switch, for example, one of the shock switches may be composed of a metal cavity and a metal ball, wherein the metal ball may freely move in the metal cavity, and when the ball moves to one side, two electrodes of the shock switch are conducted, and when the ball moves to the other side, two electrodes of the shock switch are not conducted any more, so that when the shock switch moves, the ball moves back and forth on both sides of the metal cavity, thereby generating an oscillation signal. Because the vibration switch has the advantages of low cost and easy installation, the design difficulty and the manufacturing cost of a circuit can be effectively reduced, and in addition, compared with a normally open or normally closed vibration sensor with an elastic element arranged inside, the vibration switch has higher sensitivity. Further, in other embodiments, the shock switch may be replaced by other components.

In an alternative embodiment, as shown in fig. 3, the signal isolation circuit includes a coupling capacitor C1 and a second pull-up resistor R2, where one end of the coupling capacitor C1 is connected to the shock sensing circuit, the other end of the coupling capacitor C1 is connected to the control end of the switching circuit, and the end of the coupling capacitor C1 connected to the switching circuit is further connected to the power supply through the second pull-up resistor R2.

In the above embodiment, when the voltage value at the output end of the vibration sensing circuit is a constant level signal, the voltage at the output end of the signal isolation circuit will keep a high level under the action of the third pull-up resistor R2; when the voltage value of the output end of the vibration sensing circuit is an oscillating level signal, the voltage of the output end of the signal isolation circuit can output the oscillating level signal under the action of the coupling capacitor, and in this way, the signal isolation circuit can effectively transmit the received level signal to the switching circuit.

In the above embodiment, the coupling capacitor may play a role in signal isolation, and the signal isolation circuit formed by the coupling capacitor and the second pull-up resistor may not cause additional power consumption, so that the signal isolation circuit may effectively reduce the power consumption value of the shock wake-up circuit.

In an alternative embodiment, as shown in fig. 3, the switching circuit includes a field effect transistor Q1, a second current limiting resistor R4 and a pull-down resistor R3, where a gate of the field effect transistor Q1 is connected to an output end of the signal isolation circuit, a source of the field effect transistor Q1 is connected to a power supply, a drain of the field effect transistor Q1 is connected to a vibration wake-up pin of the control circuit through the second current limiting resistor R4, and the vibration wake-up pin of the control circuit is further connected to a ground end through the pull-down resistor R3. In this embodiment, the second current limiting resistor R4 can prevent the control circuit from erroneously configuring the shock wake-up pin to be a push-pull output low level, so that the high current generated when the field effect transistor Q1 is in the exactly on state may damage the shock wake-up pins of the field effect transistor Q1 and the control circuit; the pull-down resistor R3 can prevent the accumulated charges generated when the fet Q1 is in the off state for a long time from damaging the fet Q1 when the control circuit erroneously configures the shock wake-up pin to float.

In the above embodiment, when the voltage value at the output end of the vibration sensing circuit is a constant level signal, the field effect transistor is turned off, the switching circuit outputs a low level signal, and the control circuit receives the low level signal; when the voltage value of the output end of the vibration sensing circuit is an oscillating level signal, the field effect transistor is continuously switched between on and off, the switching circuit outputs the oscillating level signal, and when the switching circuit outputs a high level signal, the vibration awakening pin is pulled to be high level, and the control circuit is awakened.

In the above embodiment, the field effect transistor may perform a signal conversion function, that is, when the vibration sensing circuit does not collect the vibration signal, the field effect transistor is always in the off state, so that the switch circuit does not consume additional electric power, and therefore, the switch circuit may effectively reduce the power consumption value of the vibration wake-up circuit.

In one embodiment, as shown in fig. 4, an electronic device is provided, where the electronic device includes a control circuit and a shock wake-up circuit, and the shock wake-up circuit is connected to the control circuit and is used to detect whether the electronic device moves (shakes), and if the electronic device moves, the shock wake-up circuit may output a shock wake-up signal to the control circuit by generating a high-low level mode, and the control circuit may selectively enable the shock wake-up function or disable the shock wake-up function. When the control circuit enables the vibration awakening function, the control circuit responds to the vibration awakening signal and executes a corresponding workflow; when the control circuit turns off the shock wake-up function, the control circuit does not respond to the shock wake-up signal. In this embodiment, the vibration wake-up circuit provided by any one of the embodiments may be used to detect whether the electronic device moves, so as to improve accuracy of detecting whether the electronic device moves by the electronic device, thereby reducing the number of times that the electronic device is awakened by mistake, reducing power consumption of the electronic device, and improving cruising ability of the electronic device.

In an alternative embodiment, the electronic device further comprises a wireless location module, wherein the wireless location module is coupled to the control circuit and is operable to perform the location operation. In this embodiment, the wireless positioning module may specifically be a WIFI communication module, a bluetooth communication module, a UWB communication module, and so on. The wireless positioning module can be used for receiving and transmitting wireless positioning signals with other electronic devices or other positioning base stations, and the current position information of the electronic device is obtained by utilizing a TDOA or TOF positioning calculation algorithm and the like.

In an alternative embodiment, the electronic device further includes a power supply circuit, where the power supply circuit is respectively connected to the shock wake-up circuit, the wireless positioning circuit and the control circuit, and is configured to provide power supply to the shock wake-up circuit, the wireless positioning circuit and the control circuit.

In an alternative embodiment, the electronic device may be a positioning tag, and may be applied in a wireless positioning scenario. Specifically, in the wireless positioning scene, the wireless positioning base station can be used as a fixed positioning anchor point, and the positioning tag can be worn on personnel, equipment or vehicles to be used as a movable positioned target. The vibration sensing circuit of the embodiment can effectively reduce the power consumption of the positioning tag and improve the endurance of the positioning tag.

In the prior art, the power consumption of the electronic device can be reduced by adopting a software mode, and the cruising ability of the electronic device is improved, for example, a control circuit in the electronic device can improve the cruising ability of the electronic device by adopting a mode switching mode. Generally, an electronic device has two modes, a sleep mode and an operation mode, in which the electronic device can execute some workflow and implement some functions, and in the sleep mode, the electronic device can shut down all unnecessary functions to save power. Generally, the sleep mode and the operation mode of the electronic device may be switched, for example, the electronic device may enter the sleep mode from the operation mode when the electronic device is not in operation for a period of time, and the electronic device may reenter the operation mode from the sleep mode when the electronic device enables a wake-up function and the current state meets the wake-up condition.

In the conventional mode switching manner, after the electronic device enters the operation mode from the sleep mode, the electronic device continues to operate until the electronic device does not need to operate for a long time. For example, an electronic device for positioning is in a sleep mode in a state of being stationary for a long time, and is awakened and enters an operating mode after moving, after which the electronic device continuously performs a positioning procedure (i.e., is always in the operating mode during moving) during moving, until the electronic device enters the sleep mode again after entering the state of being stationary for a long time. However, such a mode switching manner also wastes a large amount of power consumption of the electronic device and reduces the cruising ability of the electronic device.

In view of the above problems, in an example, as shown in fig. 5, a power saving method is provided, which is described by taking an example that the method is applied to the control circuit of the electronic device provided in any of the foregoing embodiments, in this example, the control circuit that runs the power saving method is further connected to the shock wake-up circuit provided in any of the foregoing embodiments, and the power saving method includes the following steps:

101. when the electronic device is in the first sleep mode, the electronic device is awakened for a first period of time.

102. And controlling the electronic device to execute the first workflow, and controlling the electronic device to enter a second sleep mode after the electronic device executes the first workflow.

Wherein the first sleep mode refers to a sleep mode in which a timed wake-up function is enabled alone; the second sleep mode refers to a sleep mode in which a shock wake-up function and a timed wake-up function are simultaneously enabled; the first workflow refers to an operation flow related to a function requirement of the electronic device itself and an operation flow required for switching to the second sleep mode, and the operation flow related to the function requirement of the electronic device itself may be, for example, a positioning operation flow executed by a positioning tag, etc. In this embodiment, enabling the timed wake-up function means that in the sleep mode, if one timing period ends, the electronic device is woken up and enters into the working mode; enabling the shock wake-up function refers to the electronic device being woken up and entering an operational mode if the electronic device is in motion in a sleep mode.

Specifically, when the electronic device is in the first sleep mode, the electronic device is awakened after a timing period is finished, that is, the electronic device is awakened in a preset first period, after the electronic device is awakened, a first workflow can be executed, that is, an operation flow related to the self function requirement is executed, so that the self function is realized, after the execution of the first workflow is completed, the electronic device can perform mode conversion and enter a second sleep mode, after the electronic device enters the second sleep mode, the electronic device can be awakened in a timing manner or can be awakened in a vibration manner, and if the electronic device is awakened in a timing manner in the second sleep mode, the electronic device is indicated to have no movement in the sleep period after the electronic device enters the second sleep mode; if the electronic device is awakened by vibration in the second sleep mode, it is indicated that the electronic device moves in the sleep period after entering the second sleep mode, and according to the two different conditions, the electronic device can choose to execute different working procedures when being awakened next time, for example, choose to execute the operation procedure related to the own function requirement again or choose to directly enter other sleep modes, and the like, so that the electronic device can save electric quantity as much as possible without affecting the realization of the own function. Compared with the prior art that the electronic equipment immediately enters the working mode once moving and continuously executes the working flow in the working mode, the method provided by the embodiment can greatly save the power consumption of the electronic equipment and does not influence the realization of the functions of the electronic equipment.

According to the power saving method provided by the embodiment, the electronic equipment is awakened at regular time in the first sleep mode and is controlled to execute the first workflow, so that the electronic equipment can realize the self function, and after the electronic equipment executes the first workflow, the electronic equipment is controlled to enter the second sleep mode, so that the electronic equipment is always in the sleep mode at the time except the time when the first workflow is executed, the power consumption of the electronic equipment can be effectively reduced on the premise that the self function of the electronic equipment is realized, and the cruising ability of the electronic equipment is improved. In addition, the power saving method provided by the embodiment is combined with the vibration wake-up circuit provided by the embodiments, so that the stability and the accuracy of the control circuit in response to the vibration wake-up signal can be further improved, the electronic equipment cannot repeatedly execute a work flow due to response to an error signal, the power consumption of the electronic equipment is further reduced, and the cruising ability of the electronic equipment is improved.

In an alternative embodiment, the above power saving method may further include the steps of:

103. when the electronic device is in the second sleep mode, the electronic device is awakened for a second period of time.

104. And controlling the electronic device to execute the first workflow, and controlling the electronic device to reenter the second sleep mode after the electronic device executes the first workflow.

The second sleep mode refers to a sleep mode in which the shock wake-up function and the timed wake-up function are simultaneously enabled, and the first workflow refers to an operation flow related to the function requirement of the electronic device and an operation flow required for switching to the second sleep mode. Specifically, when the electronic device is in the second sleep mode, the electronic device can be awakened at regular time or by vibration, when the electronic device is awakened at regular time, the electronic device can be awakened in a preset second period, the first workflow can be executed again after the electronic device is awakened, so that the self function is realized, and after the first workflow is executed, the electronic device can reenter the second sleep mode to wait for being awakened next time.

In the above embodiment, the electronic device may be continuously awakened at regular time and execute the first workflow in the second sleep mode, by this way, continuity of the electronic device in implementing its own functions may be ensured, and at the same time, the electronic device is always in the sleep mode in a time other than the execution of the first workflow, so that power consumption of the electronic device may be further saved, and endurance of the electronic device may be improved. In addition, the power saving method provided by the embodiment is combined with the vibration wake-up circuit provided by each embodiment, so that the power consumption of the electronic equipment can be further reduced, and the cruising ability of the electronic equipment is improved.

105. and when the electronic equipment is detected to move in the second sleep mode, controlling the electronic equipment to execute the second work flow, and controlling the electronic equipment to enter the first sleep mode after the electronic equipment executes the second work flow.

The second sleep mode refers to a sleep mode in which the shock wake-up function and the timed wake-up function are simultaneously enabled, the first sleep mode refers to a sleep mode in which the timed wake-up function is independently enabled, and the second workflow refers to an operation flow required for switching to the first sleep mode. Specifically, when the electronic device is in the second sleep mode, the electronic device may be either periodically awakened or vibration awakened, and when the electronic device is vibration awakened, the electronic device may execute a second workflow, that is, execute an operation flow required for switching from the second sleep mode to the first sleep mode, and after executing the second workflow, the electronic device may enter the first sleep mode again.

In the above embodiment, the electronic device may be switched from the second sleep mode to the first sleep mode by a shock wake-up mode, and before that, the electronic device may be switched from the first sleep mode to the second sleep mode by a timed wake-up mode, so that the first sleep mode and the second sleep mode of the electronic device may be switched from each other. Further, the difference between the first sleep mode and the second sleep mode is that the second sleep mode can be awakened by vibration, and the first sleep mode cannot be awakened by vibration, so that the second sleep mode is converted into the first sleep mode when the electronic equipment moves, the situation that the electronic equipment is continuously awakened by vibration in a moving environment can be avoided, and the vibration module consumes very much electricity, so that the conversion of the vibration-awakened electronic equipment from the second sleep mode into the first sleep mode can reduce the power consumption of the electronic equipment, for example, in an application scene, the walking time of a person carrying the electronic equipment with a positioning function can enable the vibration module to continuously work, the vibration awakening is continuously executed, the electricity consumption of the electronic equipment can be consumed, and when the first sleep mode is entered, the vibration enabling is closed, so that the electricity is saved. In addition, the power saving method provided by the embodiment is combined with the vibration wake-up circuit provided by each embodiment, so that the power consumption of the electronic equipment can be further reduced, and the cruising ability of the electronic equipment is improved.

In an alternative embodiment, the power saving method may further include the following steps when the electronic device is in the third sleep mode before entering the first sleep mode:

106. and when the electronic equipment is detected to move in the third sleep mode, controlling the electronic equipment to execute the second work flow, and controlling the electronic equipment to enter the first sleep mode after the electronic equipment executes the second work flow.

The third sleep mode refers to a sleep mode in which the shock wake-up function is enabled alone, the first sleep mode refers to a sleep mode in which the timed wake-up function is enabled alone, and the second workflow refers to an operation flow required for switching to the first sleep mode. Specifically, in the third sleep mode, the electronic device is awakened by vibration, so that the electronic device is in a stationary state in the third sleep mode, in which case, the electronic device is awakened and enters the first sleep mode once motion occurs, and the first sleep mode can be regarded as a ready state for timing work because the first sleep mode can be periodically awakened and performs a first workflow required for its own function.

In the above embodiment, when the electronic device moves in the third sleep mode, the electronic device may switch from the third sleep mode to the first sleep mode, so that the electronic device is switched from the rest state to the ready state for timing operation. In addition, the power saving method provided by the embodiment is combined with the vibration wake-up circuit provided by each embodiment, so that the power consumption of the electronic equipment can be further reduced, and the cruising ability of the electronic equipment is improved.

107. when the electronic equipment is in the second sleep mode, the electronic equipment is awakened in a third period of time, the electronic equipment is controlled to execute a third workflow, and after the electronic equipment executes the third workflow, the electronic equipment is controlled to enter the third sleep mode.

The second sleep mode refers to a sleep mode in which the shock wake-up function and the timing wake-up function are simultaneously enabled, the third sleep mode refers to a sleep mode in which the shock wake-up function is independently enabled, and the third workflow refers to an operation flow related to a function requirement of the electronic device and an operation flow required for switching to the third sleep mode. Specifically, when the electronic device is in the second sleep mode, the electronic device can be awakened at regular time or by vibration, when the electronic device is awakened at regular time, the electronic device can be awakened in a preset third period, after the electronic device is awakened, the electronic device can execute an operation flow related to the self function requirement and perform sleep mode conversion, and then enters a third sleep mode in a static state.

In the above embodiment, if the electronic device is not awakened by vibration in the second sleep mode, it is indicated that the electronic device has been stationary for a period of time, in this case, the electronic device may enter the stationary third sleep mode, and wait for the electronic device to be awakened again after movement occurs in the third sleep mode. For example, in an application scenario, after a person carrying an electronic device with a positioning function is stationary for a period of time, when the electronic device enters a third sleep mode, an operation procedure related to a function requirement of the person is not executed, so that electric quantity is saved. In addition, the power saving method provided by the embodiment is combined with the vibration wake-up circuit provided by each embodiment, so that the power consumption of the electronic equipment can be further reduced, and the cruising ability of the electronic equipment is improved.

In an alternative embodiment, the power saving method may comprise steps 101-102 and one or a combination of steps 103-104, 105, 106, 107, i.e. each of steps 103-104, 105, 106, 107 and each combination of several steps may be combined with steps 101-102 into a complete power saving method. For example, the power saving method of steps 101-102, 103-104 and 105 can continuously switch the electronic device between the first sleep mode and the second sleep mode, so that the electronic device can be awakened at regular time and execute the operation flow required by the function, and the electronic device can not continuously respond to the vibration signal in the sleep mode. For another example, the power saving method formed by steps 101-102, 106 and 107 can enable the electronic device to continuously switch among the first sleep mode, the second sleep mode and the third sleep mode, so that the electronic device can stop executing all unnecessary work flows in a static state, and keep the unnecessary work flows in the sleep mode with the lowest power consumption. Other combinations are also within the protection scope of the present embodiment, and are not described in detail herein, it is to be understood that the combinations of the steps may be selected according to the actual scenario, the present embodiment is not limited in detail herein, and the two combinations of the power saving method are described by two specific examples, however, the following examples are only used to describe the specific implementation process of the power saving method, and are not limited to the combinations of the steps.

In an alternative embodiment, the power saving method may include steps 101-102 and steps 105-107. Referring to fig. 6 and 7, steps 101-102 and steps 105-107, when embodied in specific examples, may be implemented as follows: in the initial state, the electronic equipment is in a third sleep mode which is static and waits to be awakened by vibration, when the electronic equipment moves in the static state, the electronic equipment is awakened and enters a first sleep mode for preparing timing work after executing a sleep mode conversion flow (executing a second work flow), when the electronic equipment is in the first sleep mode, the electronic equipment does not respond to a vibration signal, but can enter the second sleep mode after executing an operation flow related to the self function and executing sleep mode conversion (executing the first work flow) after the timing period is finished, and if the electronic equipment is in the second sleep mode and is awakened by vibration, the flow for executing sleep mode conversion (executing the second work flow) and then reenters the first sleep mode for preparing timing work; if the electronic equipment is awakened at regular time in the second sleep mode, executing the operation flow related to the self function, performing sleep mode conversion (executing a third work flow), entering the third sleep mode, and after the electronic equipment enters the third sleep mode, returning the mode conversion mode and the work flow execution mode to the initial state again, and continuously and circularly running in the mode.

In an alternative embodiment, the power saving method described above may include steps 101-107. Referring to fig. 8 and 9, when the above steps are embodied in a specific example, the implementation procedure may be: in the initial state, the electronic equipment is in a third sleep mode which is static and waits to be awakened by vibration, when the electronic equipment moves in the static state, the electronic equipment is awakened and enters a first sleep mode for preparing timing work after executing a sleep mode conversion flow (executing a second work flow), when the electronic equipment is in the first sleep mode, the electronic equipment does not respond to a vibration signal, but can enter the second sleep mode after executing an operation flow related to the self function and executing sleep mode conversion (executing the first work flow) after the timing period is finished, and if the electronic equipment is in the second sleep mode and is awakened by vibration, the flow for executing sleep mode conversion (executing the second work flow) is executed, and then the electronic equipment reenters the first sleep mode for preparing timing work; if the electronic equipment is awakened at regular time in the second sleep mode and does not reach the preset rest time, executing an operation flow related to the self function and performing sleep mode conversion (executing the first work flow), and then re-entering the second sleep mode; if the electronic equipment is awakened at regular time in the second sleep mode and reaches the preset rest time, executing the operation flow related to the self function, performing sleep mode conversion (executing a third work flow), entering the third sleep mode, and after the electronic equipment enters the third sleep mode, returning the mode conversion mode and the work flow execution mode to the initial state again, and continuously and circularly running in the mode.

In both of the above specific embodiments, the electronic device may switch between the first sleep mode, the second sleep mode, and the third sleep mode. Wherein the two embodiments differ in that: when the electronic device is in the second sleep mode, the first embodiment enters the third sleep mode after resting for one period, and the second embodiment enters the third sleep mode after resting for a plurality of periods, so that the period and the duration of entering the third sleep mode set by the two embodiments are different. Further, the two embodiments are identical in that: the first sleep mode and the second sleep mode of the electronic equipment can be mutually converted in the motion state, so that the electronic equipment can be continuously awakened at regular time and execute an operation flow related to the self function in the motion state, and in the process, if motion occurs in a timing period, the vibration is not repeatedly responded in the period, so that the electric quantity is saved; after a period of rest, the electronic device enters a third sleep mode, in which the electronic device is not awakened at regular time, and the electronic device is kept in a most energy-saving state until the electronic device returns to a motion state again, so that the electronic device continuously and circularly reciprocates. Therefore, the power consumption of the electronic equipment can be effectively reduced by the two embodiments, and the endurance time of the electronic equipment can be greatly prolonged. In some specific application scenarios, the second embodiment enters the third sleep mode after a plurality of periods of rest, so that the power consumption is saved and the continuity of the function execution can be improved. In addition, the power saving method provided by the two specific embodiments is combined with the vibration wake-up circuit provided by each embodiment, so that the power consumption of the electronic equipment can be further reduced, and the cruising ability of the electronic equipment is improved.

In an alternative embodiment, the method of performing the first workflow may comprise the steps of:

201. and transmitting and/or receiving the wireless positioning signal, and performing positioning operation according to the wireless positioning signal.

202. Judging whether a preset vibration mark is in a vibrated state or not, and if the vibration mark is in the vibrated state, converting the vibration mark into an unbibrated state.

203. Judging whether the preset non-vibration mark is smaller than a preset threshold value or not, and if the non-vibration mark is smaller than the preset threshold value, accumulating the non-vibration mark.

The first workflow refers to an operation flow related to a function requirement of the electronic device and an operation flow required for switching to the second sleep mode, and in this embodiment, the first workflow needs to be executed when the electronic device wakes up from the first sleep mode at regular time, switches to the second sleep mode, and re-enters the second sleep mode after waking up from the second sleep mode at regular time. Specifically, the electronic device may perform positioning communication by transceiving wireless positioning signals with other electronic devices or other positioning base stations, and then obtain current position information of the electronic device by using a positioning calculation algorithm such as TDOA or TOF or directly by receiving positioning information sent by other devices, so as to complete a positioning operation flow of the electronic device. It should be understood that, in this embodiment, the operation flow related to the function requirement of the electronic device is a positioning operation flow, but in other embodiments, the operation flow related to the function requirement of the electronic device may be other operation flows, which is not limited herein.

Further, after completing the positioning operation procedure, the electronic device may perform a mode conversion operation procedure of the second sleep mode. In this embodiment, the mode conversion may be performed by adopting the method of step 202 or step 203, where the method of step 202 is to determine whether the preset vibration identifier is in a "vibrated state", and if the vibration identifier is in the "vibrated state", it indicates that the electronic device has been vibrated in the current sleep period and the current sleep period has ended, so that the "vibrated state" may be converted into an "non-vibrated state" at this time, so that the electronic device may mark whether the electronic device has been vibrated in the current sleep period again by the vibration identifier in the next sleep period. The method of step 203 is to determine whether the preset non-vibration identifier is smaller than a preset threshold, if the non-vibration identifier is smaller than the preset threshold, it indicates that the current non-vibration duration (rest duration) of the electronic device does not reach the specified duration, and the electronic device does not need to enter the third sleep mode with the lowest power consumption, where the non-vibration identifier may be accumulated to mark the current rest cycle number of the electronic device. It should be noted that, in step 202 and step 203, the two methods may be selected, and in step 202, the vibration identifier may only mark whether the electronic device vibrates in one sleep period, and in step 203, the non-vibration identifier may continuously mark whether the electronic device vibrates in a plurality of sleep periods, where the application scenarios of the two methods are different, and the user may select or switch according to the actual needs.

In the above embodiment, by setting the vibration identifier to the non-vibration state or performing the accumulation operation on the non-vibration identifier in the first workflow, the duration of the electronic device in the current stationary state may be marked, so that it is convenient to determine whether to continue to perform the timing operation to implement the self-function or to enter the stationary sleep state for a longer time according to the stationary duration, so as to save power consumption. The method of step 202 is adopted to mark the rest duration, so that the electronic device can enter a rest sleep state after being at rest for one period, and the power consumption of the electronic device can be further reduced; the method of step 203 is adopted to mark the rest duration, so that the electronic device can enter a rest sleep state after being in rest for a plurality of periods, and the continuity of the function execution of the electronic device can be improved while the power consumption of the electronic device is saved. In addition, by transceiving wireless positioning signals and performing positioning operations in the first workflow, wireless positioning functions of the electronic device may be implemented. The power saving method provided by the embodiment is combined with the vibration wake-up circuit provided by the embodiments, so that the power consumption of the electronic equipment can be further reduced, and the cruising ability of the electronic equipment is improved.

In an alternative embodiment, the method of performing the second workflow may comprise the steps of:

301. and converting the vibration identifier from the non-vibration state to the vibration state.

302. And executing a zero clearing operation on the non-vibration mark.

The second workflow refers to an operation flow required for switching to the first sleep mode, and in this embodiment, the second workflow needs to be executed for switching to the first sleep mode after being awakened from the second sleep mode and for switching to the first sleep mode after being awakened from the third sleep mode. In this embodiment, the mode conversion may be performed by adopting the method of step 301 or step 302, where the method of step 301 is to convert the vibration identifier from the "non-vibration state" to the "vibrated state" so as to mark that the electronic device has moved in the current sleep period; the method of step 302 is to perform a zero clearing operation on the unshocked identifier, so as to zero the current unshocked duration (static duration) of the electronic device, so that the electronic device can reuse the unshocked identifier for timing. It should be noted that, in step 301 and step 302, the difference between the two methods is that in step 301, the vibration identifier can only mark whether the electronic device vibrates in one sleep period, and in step 203, the non-vibration identifier can continuously mark whether the electronic device vibrates in multiple sleep periods, so that the application scenarios of the two methods are different, and the user can select or switch according to the actual needs.

In the above embodiment, by setting the vibration identifier to the vibrated state in the second workflow that is awakened by vibration, or performing the zero clearing operation on the non-vibrated identifier, the time when the electronic device moves can be marked, so that the electronic device is convenient to calculate the time when the electronic device is in the static state. The method of step 202 and step 301 is adopted to calculate the duration of the electronic device in the static state, so that the electronic device can enter the static sleep state after being in a static period, and the power consumption of the electronic device can be further reduced; the method of step 203 and step 302 is adopted to calculate the time length of the electronic device in the static state, so that the electronic device can enter the static sleep state after being static for a plurality of periods, and the continuity of the function execution of the electronic device can be improved while the power consumption of the electronic device is saved. In addition, the power saving method provided by the embodiment is combined with the vibration wake-up circuit provided by each embodiment, so that the power consumption of the electronic equipment can be further reduced, and the cruising ability of the electronic equipment is improved.

In an alternative embodiment, the method of performing the third workflow may comprise the steps of:

401. And transmitting and/or receiving the wireless positioning signal, and performing positioning operation according to the wireless positioning signal.

402. Judging whether the vibration mark is in a non-vibration state, and if the vibration mark is in the non-vibration state, controlling the electronic equipment to enter a third sleep mode.

403. Judging whether the non-vibration mark is larger than or equal to a preset threshold value, and if the non-vibration mark is larger than or equal to the preset threshold value, controlling the electronic equipment to enter a third sleep mode.

The third workflow refers to an operation flow related to a function requirement of the electronic device itself and an operation flow required for switching to the third sleep mode, and in this embodiment, switching to the third sleep mode after the wake-up from the second sleep mode at regular time requires executing the third workflow. Specifically, the electronic device may perform positioning communication by transceiving wireless positioning signals with other electronic devices or other positioning base stations, and then obtain current position information of the electronic device by using a positioning calculation algorithm such as TDOA or TOF or directly by receiving positioning information sent by other devices, so as to complete a positioning operation flow of the electronic device. It should be understood that, in this embodiment, the operation flow related to the function requirement of the electronic device is a positioning operation flow, but in other embodiments, the operation flow related to the function requirement of the electronic device may be other operation flows, which is not limited herein.

Further, after completing the positioning operation procedure, the electronic device may execute a mode conversion operation procedure of the third sleep mode. In this embodiment, the mode conversion may be performed by using the method of step 402 or step 403, where the method of step 402 is to determine whether the preset vibration identifier is in an "unbibrated state", and if the vibration identifier is in the "unbibrated state", it indicates that the electronic device has not moved in the current sleep period, and the current sleep period has ended, so that the electronic device may be considered to have been stationary for a certain period of time, and at this time, the electronic device may be controlled to enter the third sleep mode with the lowest power consumption. The method of step 403 is to determine whether the preset non-vibration identifier is greater than or equal to the preset threshold, and if the non-vibration identifier is greater than or equal to the preset threshold, it indicates that the current non-vibration duration (rest duration) of the electronic device has reached the specified duration, where the electronic device may be controlled to enter the third sleep mode with the lowest power consumption. It should be noted that, in step 402 and step 403, the difference between the two methods is that in step 402, the vibration identifier can only determine the static duration of the electronic device through the duration of one sleep period, while in step 403, the non-vibration identifier can determine the static duration of the electronic device through the durations of multiple sleep periods, and the application scenarios of the two methods are different, so that the user can select or switch according to the actual needs.

In the above embodiment, by determining whether the vibration identifier is in the vibration state or whether the non-vibration identifier is greater than or equal to the preset threshold in the third workflow, the electronic device may be enabled to confirm whether the rest period of time reaches the predetermined period of time, and if the rest period of time reaches the predetermined period of time, enter the rest sleep state with the lowest power consumption, so as to reduce the power consumption. The method of step 202, step 301 and step 402 is adopted to confirm whether the rest time length reaches the preset time length, so that the electronic equipment can enter a rest sleep state after being at rest for one period, and the power consumption of the electronic equipment can be further reduced; by adopting the methods of the step 203, the step 302 and the step 403 to confirm whether the resting duration reaches the preset duration, the electronic equipment can enter a resting sleep state after resting for a plurality of periods, so that the power consumption of the electronic equipment is saved, and the continuity of the function execution of the electronic equipment can be improved. Meanwhile, by receiving and transmitting wireless positioning signals and executing positioning operation, the electronic equipment can confirm the current position before entering a static dormant state. In addition, the power saving method provided by the embodiment is combined with the vibration wake-up circuit provided by each embodiment, so that the power consumption of the electronic equipment can be further reduced, and the cruising ability of the electronic equipment is improved.

In an alternative embodiment, a method of entering a first sleep mode may include the steps of:

501. enabling a timed wake-up function of the electronic device to wake up the electronic device in a first period of time;

502. and turning off the vibration wake-up function of the electronic equipment.

503. And controlling the electronic equipment to enter a dormant state.

Wherein the first sleep mode refers to a sleep mode in which the timed wake-up function is enabled alone. Specifically, before entering the first sleep mode, the timed wake-up function of the electronic device may be enabled first, so that the electronic device may be wake-up at a fixed time, then the vibration wake-up function of the electronic device is turned off, so that the electronic device may not be wake-up by vibration, finally the electronic device is controlled to enter the sleep mode, and after the setting is completed, the electronic device enters the first sleep mode.

In the above embodiment, by enabling the timed wake-up function of the electronic device before entering the first sleep mode, the electronic device may be in a ready state of being periodically woken up, so that the electronic device may execute the workflow at a set time, and may be in a sleep state when not executing the workflow, so as to reduce power consumption. By closing the vibration wake-up function of the electronic equipment, the electronic equipment does not need to respond to the vibration wake-up signal all the time when in a ready working state of being periodically waken up, so that the power consumption of the electronic equipment is reduced, and the cruising ability of the electronic equipment is improved. In addition, the power saving method provided by the embodiment is combined with the vibration wake-up circuit provided by each embodiment, so that the power consumption of the electronic equipment can be further reduced, and the cruising ability of the electronic equipment is improved.

602. enabling a shock wake-up function of the electronic device to wake up the electronic device upon detection of motion;

603. and controlling the electronic equipment to enter a dormant state.

The second sleep mode refers to a sleep mode in which a shock wake-up function and a timer wake-up function are simultaneously enabled. Specifically, before entering the second sleep mode, the timed wake-up function of the electronic device may be enabled first, so that the electronic device may be wake-up at a fixed time, then the vibration wake-up function of the electronic device may be enabled, so that the electronic device may be wake-up by vibration, finally the electronic device is controlled to enter the sleep mode, and after the setting is completed, the electronic device enters the second sleep mode.

In the above embodiment, by enabling the timed wake-up function and the vibration wake-up function of the electronic device before entering the second sleep mode, the electronic device can be in a ready state of being periodically wake-up and vibration wake-up at any time, so that the electronic device can execute a related workflow at a set time, can respond to the vibration wake-up signal at any time to determine whether the electronic device is in a motion state, and can be in a sleep state when the workflow is not executed, thereby reducing the power consumption of the electronic device. In addition, the power saving method provided by the embodiment is combined with the vibration wake-up circuit provided by each embodiment, so that the power consumption of the electronic equipment can be further reduced, and the cruising ability of the electronic equipment is improved.

In an alternative embodiment, the method of entering the third sleep mode may include the steps of:

701. closing a timing wake-up function of the electronic equipment;

702. enabling a shock wake-up function of the electronic device to wake up the electronic device upon detection of motion;

703. and controlling the electronic equipment to enter a dormant state.

The third sleep mode refers to a sleep mode in which a vibration wake-up function is independently enabled, specifically, before entering the second sleep mode, the timing wake-up function of the electronic device may be turned off first, so that the electronic device may not be wake-up at a timing, then the vibration wake-up function of the electronic device is enabled, so that the electronic device may be wake-up by vibration, finally, the electronic device is controlled to enter the sleep state, and after the setting is completed, the electronic device enters the third sleep mode.

Steps 202, 301 and 402 form a set of mode conversion schemes, namely a set of mode conversion schemes corresponding to the vibration marks; steps 203, 303 and 403 form another set of mode conversion schemes, that is, form a set of mode conversion schemes corresponding to "no vibration mark", and the following two specific examples are used to illustrate two combination modes of the power saving method, and it should be noted that the following examples are only used to illustrate a specific implementation procedure of the power saving method, and are not used to limit the combination modes of the steps.

In an alternative embodiment, the power saving method may include steps 101-102, 105-107, 201-202, 301, 401-402, 501-503, 601-603, and 701-703. Referring to fig. 10, the implementation process of the above steps may be: in the initial state, the electronic equipment waits for being awakened by vibration in a third sleep mode, after vibration occurs, the electronic equipment is awakened, after judging that the awakening source is in vibration awakening, the electronic equipment sets a vibration identifier as a vibration state and enters a first sleep mode, when the electronic equipment is in the first sleep mode, the electronic equipment does not respond to a vibration signal, but is awakened at regular time after the end of a timing period, after judging that the awakening source is in timing awakening, the electronic equipment executes a positioning process, then judges whether the vibration identifier is in the vibration state, if the vibration identifier is in the vibration state, the electronic equipment is converted into the non-vibration state and enters a second sleep mode, and if the electronic equipment is in vibration awakening in the second sleep mode, the vibration identifier is reset into the vibration state and enters the first sleep mode to wait for being awakened at regular time; if the electronic equipment is awakened at regular time in the second sleep mode, the positioning process is executed again, whether the vibration mark is in an 'unbibrated state' or not is judged, if the vibration mark is in the 'unbibrated state', the electronic equipment enters the third sleep mode, and after the electronic equipment enters the third sleep mode, the mode conversion mode and the workflow execution mode return to the initial state again, and the electronic equipment is continuously and circularly operated in the mode.

In an alternative embodiment, the power saving method may include steps 101-107, steps 201 and 203, step 303, steps 401 and 403, steps 501-503, steps 601-603, and steps 701-703. Referring to fig. 11, the implementation procedure of the above steps may be: in the initial state, the electronic equipment is in a third sleep mode and waits to be awakened by vibration, after vibration occurs, the electronic equipment is awakened, after judging that the awakening source is vibration awakening, the electronic equipment clears an unbibrated mark and enters a first sleep mode, when the electronic equipment is in the first sleep mode, the electronic equipment does not respond to vibration signals, but is awakened at regular time after the end of a timing period, the electronic equipment executes a positioning process after judging that the awakening source is the regular awakening, then judges whether the value of the unbibrated mark is smaller than a preset threshold value, if the value of the unbibrated mark is smaller than the preset threshold value, the electronic equipment enters a second sleep mode after executing accumulation operation on the unbibrated mark, if the electronic equipment is vibration awakened in the second sleep mode, the unbibrated mark is cleared again, and enters the first sleep mode and waits to be awakened at regular time; if the electronic equipment is awakened at fixed time in the second sleep mode, executing a positioning process and judging whether the value of the non-vibration mark is smaller than a preset threshold value, if so, executing accumulation operation on the non-vibration mark and then entering the second sleep mode; if the value of the non-vibration mark is greater than or equal to the preset threshold value, entering a third sleep mode, and after the electronic equipment enters the third sleep mode, returning the mode conversion mode and the workflow execution mode to the initial state again, and continuously and circularly running in the mode.

In both of the above specific embodiments, the electronic device may switch between the first sleep mode, the second sleep mode, and the third sleep mode. Wherein the two embodiments differ in that: when the electronic device is in the second sleep mode, the first embodiment enters the third sleep mode after resting for one period, and the second embodiment enters the third sleep mode after resting for a plurality of periods, so that the period and the duration of entering the third sleep mode set by the two embodiments are different. Further, the two embodiments are identical in that: in the motion state, the first sleep mode and the second sleep mode of the electronic equipment can be mutually converted, so that the electronic equipment can be continuously awakened at regular time and execute a positioning process in the motion state, and in the process, if motion occurs in a timing period, vibration is not repeatedly responded in the period, so that the electric quantity is saved; after a period of rest, the electronic device enters a third sleep mode, in which the electronic device is not awakened at regular time, and the electronic device is kept in a most energy-saving state until the electronic device returns to a motion state again, so that the electronic device continuously and circularly reciprocates. Therefore, the power consumption of the electronic equipment can be effectively reduced by the two embodiments, and the endurance time of the electronic equipment can be greatly prolonged. In addition, the power saving method provided by the two specific embodiments is combined with the vibration wake-up circuit provided by each embodiment, so that the power consumption of the electronic equipment can be further reduced, and the cruising ability of the electronic equipment is improved.

In an alternative embodiment, the power saving method may be applied to a location tag of a wireless location scene. Specifically, in the wireless positioning scene, the wireless positioning base station can be used as a fixed positioning anchor point, and the positioning tag can be worn on personnel, equipment or vehicles to be used as a movable positioned target. In many wireless location scenarios, a person, device or vehicle being located may be stationary for a long period of time, e.g., in a person location system, a person may take a location tag off and leave the wireless location scenario after work, and, e.g., a device in the wireless location scenario may be stationary somewhere for a long period of time. When the positioning tag is in a static state, the position coordinate of the positioning tag does not need to be updated in real time, and the current position of the tag can be judged only by updating the last positioning position before the positioning tag enters the static state, and then the positioning tag can enter the dormant state.
