Description

Technical Field

[0001] The present invention relates to the field of computer technology, and particularly to a wake-up method, device, equipment and medium. Background Art

[0002] There are some existing low-power products. These products are in a sleep state most of the time and are usually awakened by a wake-up tool at regular intervals. After being awakened, they quickly enter the sleep state again. Since the batteries of these products are mostly disposable and cannot be charged, and the products need to send high-frequency data when they are in the normal working state after being awakened, which consumes a relatively large amount of battery power. While in the sleep state, the power consumption is very low. Therefore, in order to save power and extend the battery life, only when the wake-up tool sends a carrier signal with a specific frequency to the chip of the product, the chip will wake up the product to enter the normal working mode. In the actual use of the product, because there may be some interference signals whose signal frequencies are close to the specific frequency carrier signal, the low-power product may be awakened after receiving these interference signals, resulting in a rapid consumption of the product's battery power and reducing the service life of the product.

[0003] In summary, how to extend the service life of low-power products is a problem to be solved in this field. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a wake-up method, device, equipment and medium to extend the service life of low-power products. The specific solutions are as follows:

[0005] In a first aspect, the present application discloses a wake-up method applied to a low-power device, including:

[0006] Receiving a carrier signal with a target frequency;

[0007] Judging whether the level state of the carrier signal meets a first preset condition;

[0008] If so, perform wake-up and enter the normal working state.

[0009] Optionally, the method further includes:

[0010] If the carrier signal does not meet the first preset condition, do not make a response.

[0011] Optionally, the first preset condition is that the level state of the carrier signal is a high level state.

[0012] Optionally, the low-power device includes a register; the method further includes:

[0013] Responding to the user's setting instruction through the register to adjust the duty cycle of the carrier signal.

[0014] In a second aspect, the present application discloses a wake-up device, which is applied to a low-power device and includes:

[0015] A signal receiving module, configured to receive a carrier signal of a target frequency;

[0016] A judgment module, configured to judge whether the level state of the carrier signal meets a first preset condition;

[0017] A working module, configured to, if so, perform wake-up and enter a normal working state.

[0018] Optionally, the wake-up device further includes:

[0019] A response selection unit, configured to, if the carrier signal does not meet the first preset condition, not make a response.

[0020] Optionally, the first preset condition in the judgment module is that the level state of the carrier signal is a high level state.

[0021] Optionally, the low-power device includes a register, and the wake-up device further includes:

[0022] A duty cycle adjustment unit, configured to respond to a user's setting instruction through the register and adjust the duty cycle of the carrier signal.

[0023] In a third aspect, the present application discloses an electronic device, including:

[0024] A memory, configured to store a computer program;

[0025] A processor, configured to execute the computer program to implement the steps of the foregoing disclosed wake-up method.

[0026] In a fourth aspect, the present application discloses a computer-readable storage medium, configured to store a computer program; wherein, when the computer program is executed by a processor, the steps of the foregoing disclosed wake-up method are implemented.

[0027] It can be seen that after the low-power product of the present application receives a carrier signal of a target frequency, it judges whether the level state of the carrier signal meets a first preset condition; if so, it performs wake-up and enters a normal working state. Thus, it can be seen that when the low-power device in the present application receives a carrier signal, it does not directly wake up and enter a normal working state, but first judges whether the current level state of the carrier signal meets the first preset condition, that is, if the current level state does not meet the first preset condition, the low-power device will not wake up and enter a normal working state. Therefore, the wake-up frequency caused by interference signals is greatly reduced, the time in the normal working state is reduced, and further, the consumption of battery power is reduced and the battery life is prolonged.

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present application in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0036] There are some existing low-power products. These products are in a sleep state most of the time and are usually woken up by a wake-up tool at regular intervals. After being woken up, they quickly enter the sleep state again. Since the batteries of these products are mostly disposable and cannot be charged, and the products need to send high-frequency data when they are in the normal working state after being woken up, which consumes more battery power. In the sleep state, the power consumption is very low. Therefore, in order to save power and extend the battery life, only when the wake-up tool sends a carrier signal with a specific frequency to the chip of the product, the chip will wake up the product to enter the normal working mode. In the actual use of the product, because there may be some interference signals with signal frequencies close to the specific frequency carrier signal, the low-power product may be woken up after receiving these interference signals, resulting in a rapid consumption of the product's battery power and reducing the product's service life.

[0037] Therefore, the present application correspondingly provides a wake-up solution to extend the service life of low-power products.

[0038] See Figure 1 As shown, an embodiment of the present application discloses a wake-up method applied to a low-power device, including:

[0039] Step S11: Receive a carrier signal of a target frequency.

[0040] In this embodiment, the power supply batteries of some low-power devices cannot be charged and are disposable batteries, such as button batteries. Therefore, the battery power is very important. Therefore, it is necessary to minimize the consumption of battery power, that is, the time when the low-power device is in the normal working state. In the prior art, when a wake-up tool sends a carrier signal of a target frequency to a low-power device, the low-power device is awakened, so that the low-power device is in the normal working state and processes related work. Among them, the target frequency is generally low frequency, that is, the carrier signal that can cause the low-power device to change from the sleep state to the normal working state is generally a low-frequency carrier signal, such as a low-frequency carrier signal with a frequency of 125K. The 125K low-frequency carrier signal is easily interfered by the surrounding environment. Especially when some frequency information in the interference signals may be similar to a certain frequency in the carrier signal received by the low-power device, such as low-frequency interference signals such as electronic interference signals around the vehicle and metal interference signals around the vehicle, the low-power device will be awakened by these interference signals to enter the normal working state, thus increasing the consumption of battery power in the low-power device.

[0041] Step S12: Determine whether the level state of the carrier signal meets a first preset condition.

[0042] In this embodiment, in order to reduce the frequency of entering the normal working state due to interference signals, after receiving the carrier signal of the target frequency, the low-power device first determines whether the level state of the signal meets the first preset condition, and if it meets, then wakes up. That is, a first preset condition can be set in advance. For example, the first preset condition is that the level state is a high-level state. Therefore, only when the level state of the carrier signal is a high-level state, the low-power device is awakened, reducing the probability of the low-power device being awakened.

[0043] Step S13: If so, perform wake-up and enter the normal working state.

[0044] In this embodiment, if it is determined that the current level state meets the first preset condition, it means that the low-power device can be awakened, that is, it changes from the sleep state to the normal working state and performs corresponding work processing. It can be understood that if it is determined that the current level state does not meet the first preset condition, it means that the low-power device can still be in the sleep state to reduce the consumption of battery power.

[0045] It can be seen that after the low-power product of the present application receives the carrier signal of the target frequency, it determines whether the level state of the carrier signal meets the first preset condition; if so, it wakes up and enters the normal working state. Thus, it can be seen that when the low-power device in the present application receives the carrier signal, it does not directly wake up and enter the normal working state, but first determines whether the current level state of the carrier signal meets the first preset condition, that is, if the current level state does not meet the first preset condition, the low-power device will not wake up and enter the normal working state. Therefore, the wake-up frequency caused by interference signals is greatly reduced, the time in the normal working state is reduced, and thus the consumption of battery power is reduced and the battery life is prolonged.

[0046] See Figure 2 As shown, the embodiment of the present application discloses a specific wake-up method, including:

[0047] Step S21: Receive the carrier signal of the target frequency.

[0048] In this embodiment, when the frequency of the carrier signal sent by the wake-up tool is not the target frequency, the low-power device cannot receive it.

[0049] Step S22: Determine whether the level state of the carrier signal meets the first preset condition, and the first preset condition is that the level state of the carrier signal is a high-level state.

[0050] In this embodiment, if the carrier signal does not meet the first preset condition, no response is made. That is, when the level state of the carrier signal is a low-level state, the low-power device does not make a response, does not need to be woken up, and thus does not need to change from the sleep state to the normal working state and still remains in the sleep state.

[0051] In this embodiment, the low-power device includes a register; the method further includes: responding to the user's setting instruction through the register to adjust the duty cycle of the carrier signal. It can be understood that the duty cycle refers to the proportion of the energization time relative to the total time within a pulse cycle, that is, the proportion of the high-level state within a cycle in a cycle, and the cycle time is the sum of the high-level time and the low-level time within a cycle. Thus, the high-level state time and the low-level state time can also be obtained. The user can adjust the duty cycle based on the actual situation. For example Figure 3 As shown in a specific duty cycle setting schematic diagram, the current duty cycle is 50%, that is, the high-level state time: the low-level state time is 1:1. However, in subsequent situations, there are more interference signals and fewer non-interference signals. Then, a setting instruction can be sent to the register, and the register responds to the setting instruction to adjust the duty cycle of the carrier signal to 25%, as Figure 4Another specific duty cycle setting schematic diagram is shown. That is, the high-level state time: the low-level state time is 1:3. Then the low-level state time is greatly increased. Therefore, when the carrier signal of the target frequency is received subsequently, the probability that its level state is in the high-level state is greatly reduced. Therefore, the time when the low-power device is in the sleep state is also extended. The probability that the frequency information of the interference signal is close to the frequency information of the target carrier signal is relatively low, for example, 1 / 100. If the duty cycle is set to 10%, then the probability that the low-power device is in the normal working state due to the interference signal is only 1 / 1000. Therefore, the effect of reducing the battery power consumption is very significant. It should be noted that in the user's setting instruction, it can also include the time information for the register to respond to this setting instruction. For example, the low-power device is set in a vehicle, and the current duty cycle is 50%, that is, the high-level state time: the low-level state time is 1:1. The probability that the vehicle is in the non-start state at night is very high. Furthermore, it is necessary to make the low-power device in the sleep state for more time. Then the user can set the response time in advance, such as the response time is from 24:00 to 3:00. Therefore, the register adjusts the current duty cycle of 50% to 5% within the time period from 24:00 to 3:00, that is, the high-level state time: the low-level state time is 1:19, reasonably planning the duty cycle, reducing the frequency that the low-power device is in the normal working state due to the interference signal, and reducing battery loss.

[0052] Step S23: If so, wake up and enter the normal working state.

[0053] Among them, for the more specific working process of the above step S22, reference can be made to the corresponding content disclosed in the foregoing embodiments, and details will not be elaborated here.

[0054] It can be seen that this application can reasonably adjust the duty cycle of the carrier signal based on the actual situation, reasonably plan the first preset condition, adjust different duty cycles for different situations, improve the user experience, be more intelligent, and can also reduce the battery loss caused by interference signals and extend the battery life.

[0055] See Figure 5 As shown, an embodiment of this application discloses a wake-up device, which is applied to a low-power device and includes:

[0058] A working module 13, configured to, if so, wake up and enter the normal working state.

[0059] It can be seen that after the low-power product of the present application receives the carrier signal of the target frequency, it determines whether the level state of the carrier signal meets the first preset condition; if so, it wakes up and enters the normal working state. Thus, it can be seen that when the low-power device in the present application receives the carrier signal, it does not directly wake up and enter the normal working state, but first determines whether the current level state of the carrier signal meets the first preset condition, that is, if the current level state does not meet the first preset condition, the low-power device will not wake up and enter the normal working state.
