Background

Some low-power products exist, which are mostly in a sleep state, and are usually awakened by an awakening tool once every a period of time, and then quickly enter the sleep state again after being awakened. Because the battery of these products is mostly disposable product, can't charge, and the product need send high frequency data when being in under normal operating condition after awakening up, and then consume more battery power, and under the dormant state, the power consumption is very low, consequently for saving the electric quantity, postpones battery life, thereby only at the chip that awakens the instrument and send specific frequency's carrier signal to the product, thereby the chip just can awaken up the product normal operating mode. In the actual use process of the product, because some interference signals close to the signal frequency of the specific frequency carrier signal exist, the low-power-consumption product may be awakened after receiving the interference signals, so that the power consumption of the product is rapidly consumed, and the service life of the product is reduced.

In conclusion, how to prolong the service life of low-power consumption products is a problem to be solved in the field.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Therefore, the awakening scheme is correspondingly provided, and the service life of a low-power-consumption product is prolonged.

Referring to fig. 1, an embodiment of the present application discloses a wake-up method, which is applied to a low power consumption device, and includes:

step S11: a carrier signal of a target frequency is received.

In this embodiment, the power supply battery of some low power consumption devices cannot be charged, and is a disposable battery, such as a button battery, so the battery power is very important, and therefore, it is necessary to reduce the consumption of the battery power as much as possible, that is, the time when the low power consumption device is in a normal operating 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 woken up, so that the low-power device is in a normal operating state to process related operations, where the target frequency is generally low, that is, the carrier signal capable of enabling the low-power device to be converted from a sleep state to the normal operating state is generally a low-frequency carrier signal, for example, a low-frequency carrier signal having a frequency of 125K, and the 125K low-frequency carrier signal is easily interfered by an ambient environment, and especially when a certain section of frequency information in some interference signals may be similar to a certain section of frequency in the carrier signal received by the low-power device, for example, low-frequency interference signals such as electronic interference signals around a vehicle, metal interference signals around the vehicle, and the like, the low-power device is woken up by the interference signals to enter the normal operating state, thereby increasing consumption of battery power in the low-power device.

Step S12: and judging whether the level state of the carrier signal meets a first preset condition or not.

In this embodiment, in order to reduce the frequency of entering the normal operating state due to the interference signal, after receiving the carrier signal of the target frequency, the low power consumption device first determines whether the level state of the signal meets a first preset condition, and if so, wakes up. That is, a first preset condition may be preset, for example, the first preset condition is that the level state is a high level state, so that only when the level state of the carrier signal is the high level state, the low power consumption device is woken up, and the probability that the low power consumption device is woken up is reduced.

Step S13: and if so, waking up and entering a normal working state.

In this embodiment, if it is determined that the current level state satisfies the first preset condition, it indicates that the low power consumption device may wake up, that is, convert from the sleep state to the normal operating state, and perform corresponding operation processing.

Therefore, after the low-power-consumption product receives the carrier signal of the target frequency, whether the level state of the carrier signal meets a first preset condition or not is judged; if yes, waking up and entering a normal working state. Therefore, when the low-power-consumption equipment receives the carrier signal, the low-power-consumption equipment does not directly wake up to enter a normal working state, but judges whether the current level state of the carrier signal meets a first preset condition or not, namely if the current level state does not meet the first preset condition, the low-power-consumption equipment cannot wake up to enter the normal working state, so that the wake-up frequency caused by interference signals is greatly reduced, the time in the normal working state is shortened, the consumption of the electric quantity of a battery is reduced, and the service life of the battery is prolonged.

Referring to fig. 2, an embodiment of the present application discloses a specific wake-up method, including:

step S21: a carrier signal of a target frequency is received.

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 may not receive the carrier signal.

Step S22: and judging whether the level state of the carrier signal meets a first preset condition, wherein the first preset condition is that the level state of the carrier signal is a high level state.

In this embodiment, if the carrier signal does not satisfy the first preset condition, no response is made. That is, when the level state of the carrier signal is the low level state, the low power consumption device does not respond, does not need to wake up, does not need to be changed from the sleep state to the normal working state, and is still in the sleep state.

In this embodiment, the low power consumption device includes a register; the method further comprises the following steps: and responding to a setting instruction of a user through the register, and adjusting the duty ratio of the carrier signal. It is understood that the duty ratio refers to a proportion of the power-on time to the total time in one pulse cycle, that is, a proportion of the high level state in one period to the total time, and the one period time is a sum of the high level time and the low level time in one period, so that the high level state time and the low level state time can also be obtained. The user may adjust the duty cycle based on actual conditions, for example, a specific duty cycle setting diagram shown in fig. 3, where the current duty cycle is 50%, that is, the high state time: the low state time is 1, but in the following cases, there are more interference signals and less non-interference signals, a setting instruction may be sent to the register, and the register adjusts the duty ratio of the carrier signal to 25% in response to the setting instruction, as shown in fig. 4, another specific duty ratio setting diagram is shown, that is, the high state time: the time of the low level state is time 1. 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, and if the duty ratio is set to 10%, the probability that the low-power consumption device is in the normal operating state due to the interference signal is only 1/1000, so that the effect of reducing the battery power consumption is very significant. It should be noted that the setting instruction of the user may also include time information of the register responding to the setting instruction, for example, when the low power consumption device is installed in a vehicle, the current duty ratio is 50%, that is, the high state time: the low-level state time is 1: the low level state is time 1.

Step S23: and if so, waking up and entering a normal working state.

For more specific working process of the step S22, reference may be made to corresponding contents disclosed in the foregoing embodiments, and details are not repeated here.

Therefore, the duty ratio of the carrier signal can be reasonably adjusted based on actual conditions, the first preset condition is reasonably planned, the duty ratios of different conditions are adjusted, the user experience feeling is improved, the intelligent effect is achieved, the battery loss caused by interference signals can be reduced, and the service life of the battery is prolonged.
