Description
Technical Field

In order to reduce the energy loss of the system, one approach is to develop a low-power consumption microphone and a sound processing chip to reduce the power of the system during operation. This approach can reduce energy consumption, but energy utilization is still low. One is to design a system with sleep and wake functions.

The mode effectively improves the energy utilization rate of the system, but the sensing and identifying module for monitoring the target sound signal still generates the loss of power supply energy. Especially in applications where the probability of occurrence of the target signal is extremely low, the power consumption of the sensor will increase further. Meanwhile, in the sleep state, the power module of the system and other modules of the system are still in the closed state but not completely closed, and the sleep power consumption still exists, which becomes one of the important factors limiting the endurance time of the system, and needs to be solved urgently.

Detailed Description
Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative and intended to explain the present application and should not be construed as limiting the present application.
The following describes a zero-power sound self-wake-up system and a wake-up method according to embodiments of the present application with reference to the drawings. Aiming at the problems of energy utilization rate and short endurance time of the sound self-awakening system in the related art mentioned in the background technology center, the sound self-awakening system with zero power consumption is provided. When the target sound signal arrives, the sound self-awakening module enters a closed state under the action of the target signal, a circuit is formed between the power supply module and the load, and the system is awakened. The near-zero power consumption monitoring of various sounds can be realized, and the energy utilization rate and the endurance time of an electronic system can be greatly improved.
Specifically, fig. 1 is a schematic structural diagram of a zero-power sound self-wake-up system according to an embodiment of the present application.
As shown in fig. 1, the zero-power sound self-wake-up system 20 includes: a power module 1, a sound self-wake-up module 2 and at least one load 3.
Wherein the negative pole of the power module 1 is connected to one end of at least one load 3. Sound links to each other with power module 1's positive pole from the one end of awakening up module 2, and sound links to each other with the other end of at least one load 3 from the other end of awakening up module 2, and after receiving sound awakening instruction, sound switches to the closed state from awakening up module 2 by the off-state for power module 1 is the power supply of at least one load 3.
It can be understood that, in the sound self-awakening system, when the target sound signal does not appear, the sound self-awakening module 2 is in an off state, an open circuit is formed between the power supply module 1 and the load 3, and the system has no energy loss and is in a zero-power-consumption sleep state. When the target sound signal arrives, the sound self-awakening module 2 enters a closed state under the action of the target signal, a circuit loop is formed between the power supply module 1 and the load 3, and the system is awakened.
Further, the zero-power-consumption sound self-awakening system 20 of the embodiment of the application can continuously monitor the target sound signal in real time without consuming power supply energy in a sleep state, and the theoretical value of monitoring power consumption is zero.
Furthermore, the sound self-awakening module 2 in the embodiment of the application is relatively independent of the power module 1 and the load 3, so that system transformation can be facilitated, and upgrading transformation from a sound-free self-awakening system to a sound self-awakening system can be realized.
In an embodiment of the present application, the at least one load 3 comprises one or more diodes.
It will be appreciated that the load may take many forms, and in the system of the embodiment of the present application, the load may be a diode, and the state of the circuit is indicated by the light emitting state of the diode, so that it can be intuitively determined whether the current system is awakened.
As shown in fig. 2, the sound self-wake-up module according to the embodiment of the present invention can be implemented in various ways, and in fig. 2, three forms of the sound self-wake-up module are shown, specifically, a mechanical switch driven by sound pressure, a sound self-wake-up module combined by a piezoelectric microphone and an electrostatic switch, and a sound self-wake-up module combined by a piezoelectric microphone and a semiconductor switch or a chip such as a triode. The following description is given by way of specific examples.
In an embodiment of the present application, the acoustic self-wake-up module is a sound pressure driven mechanical switch or a micro-mechanical switch.
Specifically, as shown in fig. 3, taking the load as an example of a light emitting diode, the power module 1, the light emitting diode 7 and the mechanical switch 4 directly driven by sound pressure are connected in series to form a loop. When the target sound signal does not appear, the mechanical switch 4 is in an open state, the circuit does not form a closed loop, and the system is in a non-power consumption state without power supply. When the target sound signal appears, the mechanical switch 4 is closed under the action of the sound pressure, and the closed state is maintained by means of the circuit design. The power module 1, the light emitting diode 7 and the mechanical switch 4 form a closed loop, the system is powered on, and the light emitting diode 7 emits optical signals outwards.
In an embodiment of the present application, the sound self-wake-up module includes: an electrostatic switch; and the anode of the first piezoelectric microphone is connected with the driving electrode of the electrostatic switch, and the cathode of the first piezoelectric microphone is grounded.
Specifically, as shown in fig. 4, taking the load as an led as an example, the power module 1, the led 7 and the electrostatic switch 9 are connected in series to form a loop. The electrostatic drive electrode of the electrostatic switch 9 is connected to the positive electrode of the piezoelectric microphone 8. When the target sound signal is not present, the electrostatic switch 9 is in an open state, the circuit does not form a closed loop, and the system is in a non-power consumption state without being powered on. When a target sound signal appears, under the action of sound pressure, the piezoelectric microphone generates a voltage signal to drive the electrostatic switch 9 to be closed, and the closed state of the electrostatic switch is kept by means of circuit design. The power module 1, the light emitting diode 7 and the electrostatic switch 9 form a closed loop, the system is powered on, and the light emitting diode 7 emits an optical signal outwards.
In an embodiment of the present application, the sound self-wake-up module includes: the negative electrode of the second piezoelectric microphone is grounded; and the grid electrode of the triode is connected with the anode of the second piezoelectric microphone, the source electrode of the triode is connected with the anode of the power supply module, and the drain electrode of the triode is connected with the load module.
Specifically, as shown in fig. 5, taking the load as an led as an example, the power module 1, the led 7 and the transistor 10 are connected in series to form a loop. The gate of the transistor 10 is connected to the positive pole of the piezoelectric microphone 8. When the target sound signal is not present, the triode 10 is in an open state, the circuit does not form a closed loop, and the system is in a non-power consumption state without power supply. When a target sound signal appears, the piezoelectric microphone generates a voltage signal under the action of sound pressure, so that the triode 10 is switched to a closed state, and the closed state is kept by means of circuit design. The power module 1, the light emitting diode 7 and the triode 10 form a closed loop, the system is powered on, and the light emitting diode 7 emits optical signals outwards.
In an embodiment of the application, the sound self-awakening module is further configured to switch the sound self-awakening module from the closed state to the open state after receiving the open instruction, and otherwise, the sound self-awakening module keeps the closed state all the time.
Specifically, the sound self-awakening module in the embodiment of the application can maintain a stable closed state after being switched from an open state to a closed state when a target sound signal arrives, and does not switch the open state at a sound frequency or open along with disappearance of the target sound signal. In a closed state, the embodiment of the application detects whether a disconnection instruction is received, and if the disconnection instruction is received, the sound self-awakening module is controlled to be switched to the disconnected state, and the self-awakening system is controlled to sleep. The disconnection instruction may be a voice sleep instruction or a manual instruction of a user. Similar to the wake-up, the self-wake-up system enters a sleep mode after receiving the target sound signal, or the user directly and manually turns off the sound self-wake-up module, which is not limited in detail. In the dormant state, the power module is physically disconnected from the load, the system is in the off state, and no dormant power consumption exists.
It should be noted that, the monitoring of the sound self-wake-up module on the sound signal does not consume power, and the switching of the switch module from the open state to the closed state does not consume power.
According to the zero-power-consumption sound self-awakening system provided by the embodiment of the application, the sound self-awakening system is formed by the power supply module, the load and the sound self-awakening module, when a target sound signal does not appear, the sound self-awakening module is in a disconnected state, a circuit is formed between the power supply module and the load, no energy loss exists, and the system is in a zero-power-consumption dormant state. When the target sound signal arrives, the sound self-awakening module enters a closed state under the action of the target signal, a circuit loop is formed between the power supply module and the load, and the system is awakened. The zero-power-consumption sound monitoring and awakening of the sound monitoring system in the dormant state can be realized, so that the dormant power consumption of the system is obviously reduced, the energy utilization rate is improved, the energy loss is reduced, and the cruising time of the system is greatly improved.
The zero-power sound self-wake-up method proposed according to the embodiment of the present application is described next with reference to the accompanying drawings.
Fig. 6 is a flowchart of a zero power consumption sound self-wake-up method according to an embodiment of the present application.
As shown in fig. 6, the zero power consumption sound self-wake-up method is used in the zero power consumption sound self-wake-up system, and includes the following steps:
s601, receiving a voice wakeup command.
S602, the sound self-awakening module is controlled to be switched from an open state to a closed state according to the sound awakening instruction, so that the power module supplies power to at least one load.
In an embodiment of the present application, after controlling the sound self-awakening module to switch from the open state to the closed state according to the sound awakening instruction, the method further includes: judging whether a disconnection instruction is received; and if an opening instruction is received, controlling the sound self-awakening module to be switched from the closed state to the open state, and otherwise, keeping the closed state all the time.
In one embodiment of the present application, the disconnection command is a voice sleep command or a manual command of a user.
It should be noted that the foregoing explanation of the zero-power sound self-wake-up system embodiment is also applicable to the zero-power sound self-wake-up method of the embodiment, and is not repeated here.
According to the zero-power-consumption sound self-awakening method provided by the embodiment of the application, when a target sound signal does not appear, the sound self-awakening module is in a disconnected state, a circuit is formed between the power module and the load, no energy loss exists, and the system is in a zero-power-consumption dormant state. When the target sound signal arrives, the sound self-awakening module enters a closed state under the action of the target signal, a circuit is formed between the power supply module and the load, and the system is awakened. The zero-power-consumption sound monitoring and awakening of the sound monitoring system in the dormant state can be realized, so that the dormant power consumption of the system is obviously reduced, the energy utilization rate is improved, the energy loss is reduced, and the cruising time of the system is greatly improved.
