Detailed Description

The invention will be described in detail hereinafter with reference to the accompanying drawings in conjunction with embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.

As described in the background, an important performance index of an electronic device is energy saving, 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 difficult to solve, and from the aspect of hardware, the shock wake-up circuit in the electronic device usually consumes more power due to the characteristics of continuous operation and uncertain states of the shock sensor pin, thereby reducing the endurance of the electronic device.

In the prior art, a vibration sensor itself is usually connected to a vibration wake-up pin of a control circuit as a vibration sensing circuit, and although such a vibration wake-up circuit can implement a vibration wake-up function of an electronic device, the vibration sensor itself may easily consume much power due to its characteristics. For example, in a common switch-type shock sensor, for example, when a shock occurs, two pins of the shock sensor are rapidly switched between on and off states; at rest, the two pins of the shock sensor are randomly in a connected state or in a disconnected state. If the two pins are properly connected when the shock sensor is in a quiescent state, then much power is consumed. For example, as shown in fig. 1, the power supply voltage Vcc in the circuit is taken as 3.3V, and the pull-down resistor inside the control circuit in the circuit is taken as 40k Ω, so when the shock sensor is in a static state and the two pins are just in a connected state, the power consumption of the shock wake-up circuit will reach 3.3V/40k Ω -82.5 uA, which is a very high power consumption value.

In view of the above problem, in one embodiment, as shown in fig. 2, a vibration wake-up circuit is provided, which can be connected to a vibration wake-up pin of a control circuit and output a vibration wake-up signal to the control circuit through the vibration wake-up pin. Specifically, the vibration wake-up circuit may include a vibration sensing circuit, a signal isolation circuit and a switch circuit, wherein the vibration sensing circuit is connected to an input terminal of the signal isolation circuit, an output terminal of the signal isolation circuit is connected to a control terminal of the switch circuit, and an output terminal of the switch circuit is connected to a vibration wake-up pin of the control circuit. When the vibration sensing circuit collects a vibration signal (that is, when the vibration sensor senses the motion of the electronic device), the signal isolation circuit can transmit the vibration signal to the switching circuit and conduct the switching circuit, so that the switching circuit can output a vibration wake-up signal (the vibration wake-up signal can be represented by a high-low level signal) and the vibration wake-up signal is received by the vibration wake-up pin of the control circuit. Furthermore, when the control circuit is in a sleep mode and the vibration awakening function is enabled, the control circuit responds to a vibration awakening signal input by the vibration awakening pin and switches from the sleep mode to a working mode; when the control circuit is in a working mode or the control circuit is in a sleep mode but the vibration wake-up function is turned off, 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 converts the collected vibration signal into a vibration wake-up signal and outputs the vibration wake-up signal to the control circuit, so that the vibration wake-up circuit has a characteristic of continuous operation, which also makes reducing the power consumption of the vibration wake-up circuit become a key factor for improving the endurance time of the electronic device.

The vibration wake-up circuit provided by the embodiment converts the vibration signal into the vibration wake-up signal in a signal transmission manner and outputs the vibration wake-up signal to the control circuit, so that the output of the signal is more accurate and stable, and the power consumption waste caused by response error of the control circuit is avoided.

In an alternative embodiment, as shown in fig. 3, the shock sensing circuit includes a shock sensor, a first pull-up resistor R1 and a first current limiting resistor R5, wherein one end of the shock sensor is connected to the ground through the first current limiting resistor R5, the other end of the shock sensor is connected to the power supply through the first pull-up resistor R1, and the end of the shock 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 shock sensor from being worn by an excessive current generated by the signal isolation circuit during discharging.

In the above embodiment, when the electronic device moves, the vibration sensor receives a continuously changing oscillation signal, and the vibration sensing circuit follows the output oscillation level signal. Specifically, when the vibration sensor does not receive the oscillation signal, the voltage value at the point a in fig. 3 is kept 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 within a very small range. For example, as shown in fig. 3, the power supply voltage Vcc in the circuit is taken as 3.3V, the first pull-up resistor R1 in the circuit is taken as 1M Ω, and the first current limiting resistor R5 is taken as 10k Ω, so that when the vibration sensor is in a static state and the two pins are just in a connected state, the power consumption of the vibration wake-up circuit is 3.3V/(1M Ω +10k Ω) ≈ 3.3 uA; when the vibration sensor is in a static state and the two pins are just in an off state, no current flows through the vibration sensor, and the power consumption of the vibration wake-up circuit is zero. The embodiment can ensure that the current value of the vibration sensor is far smaller than that when the vibration sensor is directly connected to the control circuit no matter what state the vibration sensor is in, thereby effectively reducing the power consumption of the electronic equipment and improving the cruising ability of the electronic equipment.

In an alternative embodiment, as shown in FIG. 3, the shock sensor may be a shock switch. Specifically, the structure of the vibration switch is various, for example, one of the vibration switches may be composed of a metal cavity and a metal ball, wherein the metal ball may move freely in the metal cavity, when the metal ball moves to one side, two electrodes of the vibration switch are conducted, when the metal ball moves to the other side, two electrodes of the vibration switch are not conducted, and therefore, when the vibration switch moves, the metal ball moves back and forth on two 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 the circuit can be effectively reduced, and in addition, compared with a normally open or normally closed vibration sensor internally provided with an elastic element, the vibration switch has higher sensitivity. Further, in other embodiments, the vibration 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, wherein 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 terminal of the switching circuit, and the end of the coupling capacitor C1 connected to the switching circuit is further connected to the power supply via a second pull-up resistor R2.

In the above embodiment, when the voltage value at the output terminal of the vibration sensing circuit is a constant level signal, the voltage at the output terminal of the signal isolation circuit will be kept at a high level by 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 value of the output end of the signal isolation circuit can output the oscillating level signal under the action of the coupling capacitor, and the signal isolation circuit can effectively transmit the received level signal to the switch circuit in this way.

In the above embodiment, the coupling capacitor may perform a signal isolation function, and the signal isolation circuit formed by the coupling capacitor and the second pull-up resistor may not cause extra power consumption, so that the signal isolation circuit may effectively reduce the power consumption of the shake wake-up circuit.

In an alternative embodiment, as shown in fig. 3, the switching circuit includes a fet Q1, a second current limiting resistor R4, and a pull-down resistor R3, wherein a gate of the fet Q1 is connected to an output terminal of the signal isolation circuit, a source of the fet Q1 is connected to the power supply, a drain of the fet Q1 is connected to a shock wake-up pin of the control circuit through the second current limiting resistor R4, and the shock wake-up pin of the control circuit is further connected to the ground terminal through the pull-down resistor R3. In this embodiment, the second current-limiting resistor R4 can prevent the shock wake-up pin of the control circuit and the field-effect transistor Q1 from being damaged by a large current generated when the field-effect transistor Q1 is just in a conducting state when the control circuit mistakenly configures the shock wake-up pin as a push-pull output low level; the pull-down resistor R3 can prevent the accumulated charges generated when the FET Q1 is in an off state for a long time from damaging the FET Q1 under the condition that the control circuit mistakenly configures the shock wake-up pin to be floating.

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 at a high level, and the control circuit is awakened.

In the above embodiment, the fet may perform a signal conversion function, that is, when the vibration sensing circuit does not collect a vibration signal, the fet is always in a cut-off state, so that the switching circuit does not consume extra power, and therefore, the switching circuit may effectively reduce the power consumption of the vibration wake-up circuit.

In one embodiment, as shown in fig. 4, an electronic device is provided, which includes a control circuit and a vibration wake-up circuit, where the vibration wake-up circuit is connected to the control circuit and is configured to detect whether the electronic device has moved (vibrates), and if the electronic device has moved, the vibration wake-up circuit outputs a vibration wake-up signal to the control circuit by generating a high/low level, and the control circuit can select to enable or disable the vibration 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 working process; when the control circuit turns off the vibration wake-up function, the control circuit does not respond to the vibration wake-up signal. In this embodiment, whether the electronic device moves or not may be detected by using the vibration wake-up circuit provided in any of the above embodiments, so as to improve accuracy of detecting whether the electronic device moves or not, thereby reducing the number of times that the electronic device is mistakenly woken up, reducing power consumption of the electronic device, and improving cruising ability of the electronic device.

In an optional embodiment, the electronic device further comprises a wireless positioning module, wherein the wireless positioning module is connected to the control circuit and is operable to perform positioning operations. In this embodiment, the wireless positioning module may specifically be a WIFI communication module, a bluetooth communication module, a UWB communication module, and the like. Through the wireless positioning module, the electronic equipment can transmit and receive wireless positioning signals with other electronic equipment or other positioning base stations, current position information of the electronic equipment is obtained by using positioning calculation algorithms such as TDOA (time difference of arrival) or TOF (time of flight) and the like, and in addition, the wireless positioning module can also carry out wireless communication with other external equipment so as to complete wireless positioning operation and wireless communication operation of the electronic equipment.

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

In an optional implementation, the electronic device may specifically be a positioning tag, and may be applied in a wireless positioning scenario. Specifically, in a wireless positioning scenario, the wireless positioning base station may serve as a fixed positioning anchor point, and the positioning tag may be worn on a person, a device, or a vehicle to serve as a movable positioning target. The positioning tag can effectively reduce the power consumption of the positioning tag and improve the cruising ability of the positioning tag by using the vibration sensing circuit.

In the prior art, the power consumption of the electronic device may also be reduced in a software manner, and the cruising ability of the electronic device is improved, for example, a control circuit in the electronic device may improve the cruising ability of the electronic device in a mode switching manner. Generally, an electronic device has two modes, i.e., a sleep mode and an operating mode, in which the electronic device can execute some work processes and perform some functions, and in the sleep mode, the electronic device turns off all unnecessary functions to save power. Generally, the sleep mode and the working mode of the electronic device can be switched, for example, the electronic device can enter the sleep mode from the working mode when the electronic device does not need to work for a period of time, and the electronic device can re-enter the working mode from the sleep mode when some wake-up function is enabled and the current state meets the wake-up condition.

In the conventional mode switching manner, after the electronic device enters the operating mode from the sleep mode, the electronic device continues to operate until the electronic device does not need to operate for a long time, and then the electronic device enters the sleep mode again. For example, an electronic device for positioning may be in a sleep mode in a long-time stationary state, and may be woken up and enter an operating mode after moving, and thereafter, the electronic device may continuously perform a positioning process during moving (i.e., may be in the operating mode during moving), and may not enter the sleep mode again until the electronic device enters the long-time stationary state again. 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 problem, in an embodiment, as shown in fig. 5, a power saving method is provided, which is described by taking the method as an example applied to the control circuit of the electronic device provided in any one of the above embodiments, in this embodiment, the control circuit for operating the power saving method is further connected to the vibration wake-up circuit provided in any one of the above 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 woken up for a first period of time.

102. And controlling the electronic equipment to execute the first work flow, and after the electronic equipment completes the first work flow, controlling the electronic equipment to enter a second sleep mode.

Wherein the first sleep mode refers to a sleep mode in which the timed wake-up function is separately enabled; the second sleep mode refers to a sleep mode in which both the shock wake-up function and the timed wake-up function are enabled; the first workflow refers to an operation flow related to the function requirement of the electronic device itself, such as a positioning tag executing a positioning operation flow, and an operation flow required for the transition to the second sleep mode. In this embodiment, enabling the timed wake-up function means that, in the sleep mode, if a timing cycle is over, the electronic device is woken up and enters into the working mode; enabling the shock wake-up function means that in the sleep mode, if the electronic device is moved, the electronic device is woken up and enters an operation 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, and then the electronic device can execute a first work flow, that is, an operation flow related to a self function requirement is executed, so as to realize a self function, after the execution of the first work flow is finished, the electronic device performs mode conversion and enters the second sleep mode, after the electronic device enters the second sleep mode, the electronic device can be awakened regularly or can be awakened by vibration, and if the electronic device is awakened regularly in the second sleep mode, it indicates that the electronic device does not move in the sleep period after entering the second sleep mode; if the electronic device is woken up by vibration in the second sleep mode, it indicates that the electronic device has moved in the sleep period after entering the second sleep mode, and according to the two different situations, the electronic device can select to execute different work flows when being woken up next time, for example, select to execute the operation flow related to the self function requirement again or select to directly enter other sleep modes, and the like. Compared with the prior art that the electronic equipment immediately enters the working mode once moving and continuously executes the working process in the working mode, the method provided by the embodiment can greatly save the power consumption of the electronic equipment and cannot influence the realization of the functions of the electronic equipment.

According to the power saving method provided by the embodiment, the electronic device is awakened at regular time in the first sleep mode and is controlled to execute the first work flow, so that the electronic device can realize the self function, and after the electronic device executes the first work flow, the electronic device is controlled to enter the second sleep mode, so that the electronic device can be always in the sleep mode except for the time of executing the first work flow, the power consumption of the electronic device can be effectively reduced on the premise of realizing the self function, and the cruising ability of the electronic device is improved. In addition, by combining the power saving method provided by the embodiment with the vibration wake-up circuit provided by each embodiment, the stability and accuracy of the control circuit in responding to the vibration wake-up signal can be further improved, so that the electronic device does not repeatedly execute the work flow due to the response of the error signal, the power consumption of the electronic device is further reduced, and the cruising ability of the electronic device is improved.

In an optional implementation manner, the power saving method may further include the following steps:

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

104. And controlling the electronic equipment to execute the first work flow, and after the electronic equipment completes the first work flow, controlling the electronic equipment to re-enter the second sleep mode.

The first work flow refers to an operation flow related to the function requirement of the electronic equipment and an operation flow required for converting into the second sleep mode. Specifically, when the electronic device is in the second sleep mode, the electronic device may be awakened periodically or may be awakened by vibration, when the electronic device is awakened periodically, the electronic device may be awakened in a second preset time period, and the first work flow may be executed again after the electronic device is awakened, so as to implement its own function, and after the first work flow is executed, the electronic device may reenter the second sleep mode to wait for being awakened next time.

In the above embodiment, the electronic device may be constantly awakened at regular time and execute the first work flow in the second sleep mode, and in this way, the continuity of the function of the electronic device itself may be ensured, and meanwhile, the electronic device is always in the sleep mode except for the time of executing the first work flow, which may further save the power consumption of the electronic device and improve the cruising ability of the electronic device. In addition, by combining the power saving method provided by the present embodiment with the vibration wake-up circuit provided by each of the above embodiments, the power consumption of the electronic device can be further reduced, and the cruising ability of the electronic device can be improved.

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

The second sleep mode refers to a sleep mode in which the vibration wake-up function and the timing wake-up function are simultaneously enabled, the first sleep mode refers to a sleep mode in which the timing wake-up function is separately enabled, and the second workflow refers to an operation flow required for the transition to the first sleep mode. Specifically, when the electronic device is in the second sleep mode, the electronic device may be awakened periodically or by vibration, and when the electronic device is awakened by vibration, the electronic device may execute the second workflow, that is, execute an operation flow required to switch from the second sleep mode to the first sleep mode, and after the execution of the second workflow is completed, 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 vibration wake-up, and before that, the electronic device may be switched from the first sleep mode to the second sleep mode by a timing wake-up, so that the first sleep mode and the second sleep mode of the electronic device may be switched to each other. Furthermore, the difference between the first sleep mode and the second sleep mode is that the second sleep mode can be woken up by vibration, and the first sleep mode cannot be woken up by vibration, so that the second sleep mode is converted into the first sleep mode when the electronic device moves, the electronic device can be prevented from being woken up by vibration continuously in a moving environment, and the vibration module consumes electric power very much, so that the electronic device wakened up by vibration can be converted into the first sleep mode from the second sleep mode, so that the power consumption of the electronic device can be reduced. In addition, by combining the power saving method provided by the present embodiment with the vibration wake-up circuit provided by each of the above embodiments, the power consumption of the electronic device can be further reduced, and the cruising ability of the electronic device can be improved.

In an optional implementation manner, before the electronic device enters the first sleep mode, the electronic device is in a third sleep mode, and the power saving method may further include the following steps:

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 after the electronic equipment completes the second work flow, controlling the electronic equipment to enter the first sleep mode.

The third sleep mode refers to a sleep mode in which the vibration wake-up function is separately enabled, the first sleep mode refers to a sleep mode in which the timing wake-up function is separately enabled, and the second work flow refers to an operation flow required for the transition to the first sleep mode. Specifically, in the third sleep mode, the electronic device may be waken up by vibration, and thus the electronic device may be in a static state in the third sleep mode, in which case, the electronic device may be waken up and enter the first sleep mode upon movement, and the first sleep mode may be regarded as a preparation state for a timed operation since the first sleep mode may be waken up at a timed time and perform a first workflow required by its 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 static state to the preparation state of the timed operation. In addition, by combining the power saving method provided by the present embodiment with the vibration wake-up circuit provided by each of the above embodiments, the power consumption of the electronic device can be further reduced, and the cruising ability of the electronic device can be 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 work flow, and after the electronic equipment completes the third work flow, the electronic equipment is controlled to enter the third sleep mode.

The second sleep mode refers to a sleep mode in which the vibration wake-up function and the timing wake-up function are enabled at the same time, the third sleep mode refers to a sleep mode in which the vibration wake-up function is enabled alone, and the third work flow refers to an operation flow related to the 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 may be awakened periodically or by vibration, and when the electronic device is awakened periodically, the electronic device may be awakened in a preset third time period, and after the electronic device is awakened, the electronic device may execute an operation procedure related to its own function requirement and perform a sleep mode transition, and then enter the third sleep mode in a static state.

In the above embodiment, if the electronic device is not waken up by vibration in the second sleep mode, which indicates 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 waken up again after movement occurs in the third sleep mode. For example, in an application scenario, after a person carrying the electronic device with a positioning function is stationary for a period of time, when the electronic device enters a third sleep mode, the operation flow related to the function requirement of the electronic device is not executed any more, so that the electric quantity is saved. In addition, by combining the power saving method provided by the present embodiment with the vibration wake-up circuit provided by each of the above embodiments, the power consumption of the electronic device can be further reduced, and the cruising ability of the electronic device can be improved.

In an optional embodiment, the power saving method may include step 101-. For example, in the steps 101-102, the power saving method combined with the steps 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 procedure required by the function, and the electronic device does not continuously respond to the vibration signal in the sleep mode, thereby effectively reducing the power consumption of the electronic device. For another example, in step 101-. For other combination manners, which are also within the scope of the present embodiment and are not described in detail herein, it is understood that the combination manner of each step may be selected according to an actual scenario, and this implementation is not specifically limited herein, and two combination manners of the power saving method are described below by using two specific examples, which need to be described below, where the following examples are only used to describe a specific implementation process of the power saving method, and are not used to limit the combination manner of each step.

In an optional implementation manner, the power saving method may include steps 101-102 and 105-107. Referring to fig. 6 and 7, when the steps 101-102 and 105-107 are embodied in a specific example, the implementation process may be as follows: in an initial state, the electronic equipment waits to be awakened by vibration in a static third sleep mode, 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 process (executing a second work process), when the electronic equipment is in the first sleep mode, the electronic equipment does not respond to a vibration signal, but executes an operation process related to self functions after a timing period is ended and enters a second sleep mode after executing sleep mode conversion (executing the first work process), if the electronic equipment is awakened by vibration in the second sleep mode, the process of sleep mode conversion (executing the second work process) is executed, and then the electronic equipment enters the first sleep mode for preparing timing work again; if the electronic device is awakened regularly in the second sleep mode, the electronic device executes the operation flow related to the self function, performs sleep mode conversion (executes a third work flow), and then enters a third sleep mode, and after the electronic device enters the third sleep mode, the mode conversion mode and the work flow execution mode return to the initial state again, and the electronic device continuously and circularly operates in the mode.

In an optional implementation manner, the power saving method may include steps 101-107. Referring to fig. 8 and 9, when the above steps are embodied in a specific example, the implementation process may be: in an initial state, the electronic equipment waits to be awakened by vibration in a static third sleep mode, 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 process (executing a second work process), when the electronic equipment is in the first sleep mode, the electronic equipment does not respond to a vibration signal, but executes an operation process related to self functions after a timing period is ended and enters a second sleep mode after executing sleep mode conversion (executing the first work process), if the electronic equipment is awakened by vibration in the second sleep mode, the process of sleep mode conversion (executing the second work process) is executed, and then the electronic equipment enters the first sleep mode for preparing timing work again; if the electronic equipment is awakened regularly in the second sleep mode and does not reach the preset static duration, executing an operation flow related to the self function, performing sleep mode conversion (executing a first work flow), and then re-entering the second sleep mode; if the electronic equipment is awakened regularly in the second sleep mode and reaches the preset static duration, executing an operation flow related to the self function, performing sleep mode conversion (executing a third work flow), and then entering a third sleep mode, 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 operating in the mode.

In both embodiments, the electronic device can switch between a first sleep mode, a second sleep mode, and a third sleep mode. The two embodiments are different in that: when the electronic device is in the second sleep mode, the first embodiment enters the third sleep mode after being stationary for one period, and the second embodiment enters the third sleep mode after being stationary for a plurality of periods, so that the two embodiments set the period and the duration of entering the third sleep mode to be different. Further, both 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 constantly awakened at regular time in the motion state and execute the operation flow related to the self function, 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 the electronic device is still for a period of time, the electronic device enters a third sleep mode, and in the third sleep mode, the electronic device is not awakened regularly any more, so that the electronic device is kept in a most energy-saving state until the electronic device returns to a motion state again, and the operation is repeated continuously and cyclically. Therefore, the two embodiments can effectively reduce the power consumption of the electronic device and greatly prolong the endurance time of the electronic device. In some specific application scenarios, the second embodiment enters the third sleep mode after being quiescent for a plurality of periods, so that the power consumption is saved and the continuity of the self function execution can be improved. In addition, the power saving methods provided by the two specific embodiments are combined with the vibration wake-up circuit provided by the embodiments, so that the power consumption of the electronic device can be further reduced, and the cruising ability of the electronic device can be improved.

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

201. and sending and/or receiving the wireless positioning signal, and executing positioning operation according to the wireless positioning signal.

202. And judging whether the preset vibration identifier is in a vibrated state, and if the vibration identifier is in the vibrated state, converting the vibration identifier into an un-vibrated state.

203. And judging whether the preset non-vibration identification is smaller than a preset threshold value or not, and if the non-vibration identification is smaller than the preset threshold value, performing accumulation operation on the non-vibration identification.

In this embodiment, 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 first workflow is required to be executed when the electronic device is switched to the second sleep mode after being awakened from the first sleep mode at a fixed time and when the electronic device is switched to the second sleep mode again after being awakened from the second sleep mode at a fixed time. Specifically, the electronic device may perform positioning communication in a manner of transceiving wireless positioning signals with other electronic devices or with 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 by directly receiving positioning information transmitted by other devices, so as to complete a positioning operation procedure of the electronic device. It should be understood that the operation flow related to the function requirement of the electronic device itself in this embodiment is a positioning operation flow, but in other embodiments, the operation flow related to the function requirement of the electronic device itself may also be another operation flow, and this embodiment is not limited in detail here.

Further, after completing the positioning operation procedure, the electronic device may perform a mode switching operation procedure of the second sleep mode. In this embodiment, the method of step 202 or step 203 may be adopted to perform mode transition, wherein the method of step 202 is to determine whether a preset vibration flag is in a "vibrated state", and if the vibration flag is in the "vibrated state", it indicates that the electronic device has vibrated in the current sleep cycle and the current sleep cycle has ended, so that the "vibrated state" may be transitioned to an "unsjarred state" at this time, so that the electronic device may mark whether the electronic device has vibrated in the current sleep cycle through the vibration flag again in the next sleep cycle. The method in step 203 is to determine whether the preset non-vibration flag is smaller than a preset threshold, and if the non-vibration flag is smaller than the preset threshold, it indicates that the current non-vibration duration (static 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, at this time, the non-vibration flag may be accumulated to mark the number of cycles of the electronic device that is currently static. It should be noted that, step 202 and step 203 may be selected in a different way, and the difference between the two methods is that, in step 202, the vibration flag may only mark whether the electronic device has vibrated in one sleep cycle, and in step 203, the non-vibration flag may continuously mark whether the electronic device has vibrated in a plurality of sleep cycles, and the application scenarios of the two methods are different, and the user may select or switch according to actual needs.

In the above embodiment, by setting the vibration flag to be in the non-vibration state or performing the accumulation operation on the non-vibration flag in the first workflow, the duration of the electronic device currently in the static state may be marked, so as to facilitate the subsequent determination of whether to continue to perform the timing operation to implement the self-function or to enter the static sleep state for a longer time according to the static duration to save power consumption. The method of step 202 is adopted to mark the static duration, so that the electronic device can enter a static dormant state after being static 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 static duration, so that the electronic device can enter a static dormant state after being static for a plurality of periods, thereby saving the power consumption of the electronic device and improving the continuity of the function execution of the electronic device. In addition, the wireless positioning function of the electronic equipment can be realized by receiving and sending the wireless positioning signal and executing the positioning operation in the first work flow. By combining the power saving method provided by the embodiment with the vibration wake-up circuit provided by each embodiment, the power consumption of the electronic device can be further reduced, and the cruising ability of the electronic device can be improved.

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

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

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

In this embodiment, the second workflow refers to an operation flow required for switching to the first sleep mode, and the second workflow is required to be executed when the second workflow is switched to the first sleep mode after being waken up by vibration from the second sleep mode and when the second workflow is switched to the first sleep mode after being waken up by vibration from the third sleep mode. In this embodiment, the mode transition may be performed by adopting a method in step 301 or step 302, wherein the method in step 301 is to transition the vibration flag from "non-vibration state" to "vibration state" to mark that the electronic device has moved in the current sleep cycle; the method of step 302 is to perform a zero clearing operation on the non-vibration flag to zero the current non-vibration duration (static duration) of the electronic device, so that the electronic device can reuse the non-vibration flag for timing. It should be noted that, step 301 and step 302 may be selected in a different way, and the difference between the two methods is that, in step 301, the vibration flag may only mark whether the electronic device has vibrated in one sleep cycle, and in step 203, the non-vibration flag may continuously mark whether the electronic device has vibrated in a plurality of sleep cycles, and the application scenarios of the two methods are different, and the user may select or switch according to actual needs.

In the above embodiment, the vibration flag is set to be in a vibration state in the second workflow woken up by vibration, or the non-vibration flag is cleared, so that the time when the electronic device moves can be marked, and the electronic device can calculate the time length of the electronic device in the static state conveniently. The method of step 202 and step 301 is adopted to calculate the time length of the electronic device in the static state, so that the electronic device can enter the static dormant state after being static for one 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 dormant state after being static for a plurality of periods, thereby saving the power consumption of the electronic device and improving the continuity of the function execution of the electronic device. In addition, by combining the power saving method provided by the present embodiment with the vibration wake-up circuit provided by each of the above embodiments, the power consumption of the electronic device can be further reduced, and the cruising ability of the electronic device can be improved.

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

401. and sending and/or receiving the wireless positioning signal, and executing positioning operation according to the wireless positioning signal.

402. And judging whether the vibration mark is in an un-vibration state, and if the vibration mark is in the un-vibration state, controlling the electronic equipment to enter a third sleep mode.

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

In this embodiment, 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 the third workflow needs to be executed when the electronic device is switched to the third sleep mode after being awakened from the second sleep mode at a fixed time. Specifically, the electronic device may perform positioning communication in a manner of transceiving wireless positioning signals with other electronic devices or with 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 by directly receiving positioning information transmitted by other devices, so as to complete a positioning operation procedure of the electronic device. It should be understood that the operation flow related to the function requirement of the electronic device itself in this embodiment is a positioning operation flow, but in other embodiments, the operation flow related to the function requirement of the electronic device itself may also be another operation flow, and this embodiment is not limited in detail here.

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

In the foregoing embodiment, by determining whether the vibration flag is in a vibration state or not in the third workflow, or determining whether the non-vibration flag is greater than or equal to a preset threshold, the electronic device may determine whether the static duration reaches a predetermined duration, and if the static duration reaches the predetermined duration, enter a static sleep state with the lowest power consumption to reduce power consumption. The method of step 202, step 301 and step 402 is adopted to determine whether the static duration reaches the predetermined duration, so that the electronic device can enter a static dormant state after being static for one period, and the power consumption of the electronic device can be further reduced; the method of step 203, step 302 and step 403 is adopted to confirm whether the static duration reaches the predetermined duration, so that the electronic device can enter a static dormant state after being static for a plurality of periods, thereby saving the power consumption of the electronic device and improving the continuity of the function execution of the electronic device. Meanwhile, the electronic equipment can confirm the current position before entering the static dormant state by receiving and transmitting the wireless positioning signal and executing the positioning operation. In addition, by combining the power saving method provided by the present embodiment with the vibration wake-up circuit provided by each of the above embodiments, the power consumption of the electronic device can be further reduced, and the cruising ability of the electronic device can be improved.

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

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

502. and closing the vibration awakening 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 separately enabled. Specifically, before entering the first sleep mode, the timing wake-up function of the electronic device may be enabled first, so that the electronic device may be awakened at a timing, then the vibration wake-up function of the electronic device is turned off, so that the electronic device may not be woken up by vibration, and finally the electronic device is controlled to enter the sleep state, 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 can be in a ready-to-operate state of being timed wake-up, so that the electronic device can execute a workflow at a set time and be in a sleep state when the workflow is not executed, thereby reducing power consumption. By closing the vibration awakening function of the electronic equipment, the electronic equipment does not need to respond to the vibration awakening signal all the time when being in the preparation working state of being awakened at regular time, so that the power consumption of the electronic equipment is reduced, and the cruising ability of the electronic equipment is improved. In addition, by combining the power saving method provided by the present embodiment with the vibration wake-up circuit provided by each of the above embodiments, the power consumption of the electronic device can be further reduced, and the cruising ability of the electronic device can be improved.

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

601. enabling a timed awakening function of the electronic equipment so that the electronic equipment is awakened in a second time period or a third time period;

602. enabling a shock wake-up function of the electronic device to wake up the electronic device when motion is detected to occur;

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

Wherein the second sleep mode refers to a sleep mode in which the vibration wake-up function and the timing wake-up function are simultaneously enabled. Specifically, before entering the second sleep mode, the timing wake-up function of the electronic device may be enabled first, so that the electronic device may be awakened at a timing, then the vibration wake-up function of the electronic device may be enabled, so that the electronic device may be awakened by vibration, and finally the electronic device is controlled to enter the sleep state.

In the above embodiment, the timing wake-up function and the vibration wake-up function of the electronic device are enabled before entering the second sleep mode, so that the electronic device can be in the preparation state of being timed wake-up and vibration wake-up at any time, and thus the electronic device can execute the relevant work flow at the set time, can respond to the vibration wake-up signal at any time to judge whether the electronic device is in the motion state, and can be in the sleep state when the work flow is not executed, thereby reducing the power consumption of the electronic device. In addition, by combining the power saving method provided by the present embodiment with the vibration wake-up circuit provided by each of the above embodiments, the power consumption of the electronic device can be further reduced, and the cruising ability of the electronic device can be 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 when motion is detected to occur;

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

Specifically, before entering the second sleep mode, the timing wake-up function of the electronic device may be first turned off, so that the electronic device is not awakened at a timing, then the vibration wake-up function of the electronic device is enabled, so that the electronic device may be awakened by vibration, and finally the electronic device is controlled to enter the sleep state.

In the above embodiment, the timing wake-up function of the electronic device is turned off when the electronic device enters the third sleep mode, so that the electronic device does not need to execute a timing work flow when the electronic device is in a static state, power consumption of the electronic device is reduced, and meanwhile, the electronic device can be wakened up when the electronic device moves by enabling the vibration wake-up function, thereby ensuring realization of functions of the electronic device. In addition, by combining the power saving method provided by the present embodiment with the vibration wake-up circuit provided by each of the above embodiments, the power consumption of the electronic device can be further reduced, and the cruising ability of the electronic device can be improved.

In an optional embodiment, the combination of the steps in the step 101-. Wherein, steps 202, 301 and 402 form a set of mode conversion schemes, that is, a set of mode conversion schemes corresponding to the "vibration identification" is formed; steps 203, 303, and 403 form another mode conversion scheme, that is, form a mode conversion scheme corresponding to a set of "non-vibration flag", and two combination manners of the power saving method are described below by using two specific examples, it should be noted that the following examples are only used to describe specific implementation processes of the power saving method, and are not used to limit the combination manner of each step.

In an optional embodiment, the power saving method may include steps 101-. Referring to fig. 10, the implementation process of the above steps may be: in an initial state, the electronic equipment is in a third sleep mode to wait for being awakened by vibration, after vibration occurs, the electronic equipment is awakened, after the awakening source is judged to be the vibration awakening source, the electronic equipment sets a vibration identifier to be in a 'vibrated state' and enters a first sleep mode, when the electronic equipment is in the first sleep mode, the electronic equipment does not respond to the vibration signal but is awakened at regular time after a timing period is ended, after the awakening source is judged to be the timing awakening source, the electronic equipment can execute a positioning process, then judges whether the vibration identifier is in the 'vibrated state', if the vibration identifier is in the 'vibrated state', the 'vibrated state' is converted into the 'un-vibrated state' and then enters a second sleep mode, and if the electronic equipment is awakened by vibration in the second sleep mode, the vibration identifier is reset to be in the 'vibrated state', entering a first sleep mode to wait for being awakened regularly; if the electronic equipment is awakened regularly in the second sleep mode, the positioning process is executed again and whether the vibration mark is in an 'un-vibration state' is judged, if the vibration mark is in the 'un-vibration state', the electronic equipment enters a third sleep mode, after the electronic equipment enters the third sleep mode, the mode conversion mode and the work flow execution mode return to the initial state again, and the electronic equipment continuously and circularly operates in the mode.

In an optional implementation manner, the power saving method may include steps 101-. Referring to fig. 11, the implementation process of the above steps may be: in the initial state, the electronic equipment is in a third sleep mode to wait for being awakened by vibration, and after the vibration occurs, the electronic equipment is awakened, after judging that the awakening source is the vibration awakening, the electronic equipment resets the non-vibration mark and enters a first sleep mode, when the electronic equipment is in the first sleep mode, the electronic equipment does not respond to the vibration signal, but is awakened at the timing after the timing period is over, after the wake-up source is judged to be timed wake-up, the electronic equipment executes a positioning process, then judges whether the value of the non-vibration mark is smaller than a preset threshold value, if the value of the non-vibration mark is smaller than the preset threshold value, the non-vibration mark enters a second sleep mode after being subjected to accumulation operation, if the electronic equipment is awakened by vibration in the second sleep mode, resetting the non-vibration mark again, and entering the first sleep mode to wait for timed awakening; if the electronic equipment is awakened regularly in the second sleep mode, executing a positioning process and judging whether the value of the non-vibration identifier is smaller than a preset threshold value, and if the value of the non-vibration identifier is smaller than the preset threshold value, performing accumulation operation on the non-vibration identifier and entering the second sleep mode; and if the value of the non-vibration identifier is greater than or equal to the preset threshold value, entering a third sleep mode, 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 operating in the mode.

In both embodiments, the electronic device can switch between a first sleep mode, a second sleep mode, and a third sleep mode. The two embodiments are different in that: when the electronic device is in the second sleep mode, the first embodiment enters the third sleep mode after being stationary for one period, and the second embodiment enters the third sleep mode after being stationary for a plurality of periods, so that the two embodiments set the period and the duration of entering the third sleep mode to be different. Further, both 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 constantly awakened at regular time and execute a positioning process in the motion state, and in the process, if motion occurs in a fixed time period, the vibration is not repeatedly responded in the period, so that the electric quantity is saved; after the electronic device is still for a period of time, the electronic device enters a third sleep mode, and in the third sleep mode, the electronic device is not awakened regularly any more, so that the electronic device is kept in a most energy-saving state until the electronic device returns to a motion state again, and the operation is repeated continuously and cyclically. Therefore, the two embodiments can effectively reduce the power consumption of the electronic device and greatly prolong the endurance time of the electronic device. In addition, the power saving methods provided by the two specific embodiments are combined with the vibration wake-up circuit provided by the embodiments, so that the power consumption of the electronic device can be further reduced, and the cruising ability of the electronic device can be improved.

In an optional embodiment, the power saving method may be applied to a positioning tag in a wireless positioning scenario. Specifically, in a wireless positioning scenario, the wireless positioning base station may serve as a fixed positioning anchor point, and the positioning tag may be worn on a person, a device, or a vehicle to serve as a movable positioning target. In many wireless location scenarios, the located person, device or vehicle may be stationary for a long time, for example, in a people location system, the person may remove the location tag and leave the wireless location scenario after work, and for example, the device in the wireless location scenario may be stationary for a long time in a certain place. When the positioning label is in a static state, the position coordinate of the positioning label does not need to be updated in real time, the current position of the label can be judged only by updating the last positioning position before the positioning label enters the static state, and then the positioning label can enter a dormant state. In this scenario, the power saving method described in this embodiment can not only enable the positioning tag to enter the sleep mode when the positioning tag is stationary for a long time, but also enable the positioning tag to be continuously and circularly switched in several sleep modes during the movement process, so that the positioning tag is always kept in a low-power-consumption working state. In addition, by combining the power saving method provided by the present embodiment with the vibration wake-up circuit provided by each of the above embodiments, the power consumption of the electronic device can be further reduced, and the cruising ability of the electronic device can be improved.

Further, as a specific implementation of the method shown in fig. 5 to 11, the present embodiment provides a power saving device, as shown in fig. 12, the device includes: a sleep mode wake-up module 31 and a sleep mode switching module 32.

The sleep mode wake-up module 31 is configured to wake up the electronic device at a first time period if the electronic device is in a first sleep mode;
