A signal processing method and related equipment

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on February 5, 2024, with application number 202410171484.X and application name “A signal processing method and related equipment”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of terminals, and in particular to a signal processing method and related equipment. Background Art

[0003] A terminal device is a hardware device used to implement functions such as human-computer interaction and data input and output. In different application scenarios, terminal devices can have different forms and functions, such as mobile phones, all-in-one computers, laptops, and tablets. In recent years, to enhance user experience, terminal devices have developed towards providing larger screens and more functions.

[0004] However, due to the increasing size of terminal screens and the increasing number of functional modules within terminal devices, the power consumption of terminal devices is increasing. Therefore, how to reduce the energy consumption of terminal devices is an urgent problem to be solved.

[0005] Summary of the Invention

[0006] The present application provides a signal processing method and related equipment, which can improve the accuracy of perception detection through high-frequency signals, and can also trigger high-frequency signals through the perception results of low-frequency signals to reduce device power consumption.

[0007] In a first aspect, the present application provides a signal processing method, which can be performed by a terminal device or by a component of the terminal device (e.g., a processor, a chip, or a chip system). In this method, the terminal device transmits a first signal; the terminal device receives a second signal, the second signal including a reflected signal of the first signal, the second signal being used to determine a first perception result; the terminal device transmits a third signal based on the first perception result, the third signal being transmitted at a higher frequency than the first signal; the terminal device receives a fourth signal, the fourth signal including a reflected signal of the third signal, the fourth signal being used to determine a second perception result; wherein the second perception result is used to control the energy consumption state of the first module.

[0008] Based on the above technical solution, the terminal device can trigger the transmission of a third signal with a higher transmission frequency based on the first perception result indicated by the reflected signal of the first signal with a lower transmission frequency. The second perception result indicated by the reflected signal of the third signal with a higher transmission frequency can be used to control the energy consumption state of the first module. Thus, while the accuracy of perception detection can be improved by using high-frequency signals, the high-frequency signals can also be triggered by the perception results of low-frequency signals to reduce device power consumption.

[0009] In addition, if perception detection is performed only through signals of a single frequency, signal parsing errors may occur due to the presence of interference signals in the physical space. Consequently, the terminal device may frequently trigger changes in the energy consumption state of the first module based on this error, which can easily cause damage to the first module due to frequent energy consumption changes. In the above technical solution, the process of triggering high-frequency signals through the perception results of low-frequency signals can, to a certain extent, avoid signal parsing errors caused by signals of a single frequency, thereby reducing the probability of damage to the first module due to frequent energy consumption changes.

[0010] In this application, terminal devices may include mobile phones, all-in-one computers, notebooks, tablets, etc. In different fields or scenarios, terminal devices may have different descriptions, for example, the terminal device may be replaced with other descriptions, such as electronic equipment, terminal, etc.

[0011] In this application, the transmission frequency of a signal may indicate the frequency at which the signal is transmitted within a certain time period. For example, if the transmission frequency of the third signal is higher than the transmission frequency of the first signal, it can be understood that the transmission frequency of the third signal is higher than the transmission frequency of the first signal within a certain time period (e.g., 1 second, 1 millisecond, etc.).

[0012] It should be understood that a reflected signal of a signal (e.g., a reflected signal of a first signal) can be understood as a reflected signal of the signal transmitted by a signal transmitting device, which is formed after the signal is transmitted by the signal transmitting device and collides with various objects in physical space (e.g., at least one of reflection, diffraction, or scattering) and reaches the signal transmitting device. Accordingly, the reflected signal can be used to determine a perception result, which can be understood as the reflected signal being used to perceive (or reflect) one or more of: information about the object in physical space or information about the movement of the object in physical space (e.g., human movement).

[0013] Optionally, in addition to the reflected signal formed by the signal colliding with an obstacle, the reflected signal of a signal may also include other signals, such as a direct signal formed by the signal passing between the signal transmitting device and the signal receiving device without being reflected by an obstacle, a signal generated by the communication process of other devices in the physical space, etc. Among them, the other signals can be regarded as reflected signals.

[0014] Optionally, the reflected signal can be replaced by other terms, such as echo signal, sensory feedback signal, sensory response signal, detection signal, sensory signal, etc.

[0015] It should be understood that the first module may be an energy-consuming module inside the terminal device, such as a display screen module inside the terminal device, a camera module inside the terminal device, etc. Alternatively, the first module may be an energy-consuming module external to the terminal device, such as a display device external to the terminal device, a camera module external to the terminal device, etc.

[0016] In a possible implementation of the first aspect, the terminal device sends a third signal based on the first perception result, including: when the first perception result satisfies at least one of the following, the terminal device sends the third signal, including: the first perception result indicates that there is an object moving within the area of ​​the first detection distance; or the first perception result indicates that there is an object moving within the area of ​​the first detection distance and outside the area of ​​the second detection distance, and the first detection distance is greater than the second detection distance.

[0017] Based on the above technical solution, when at least one of the above items is met, the terminal device can determine that the first perception result indicates that there is object movement in a certain area, so that the terminal device can trigger the sending of a third signal with a higher frequency, so that the movement of the object can be perceived subsequently through the reflected signal of the third signal with a higher frequency.

[0018] Optionally, the detection distance involved in this application (such as the first detection distance, the second detection distance, the third detection distance described later, the fourth detection distance, etc.) can be a pre-configured parameter (such as the factory configuration of the device), or the detection distance can be a parameter manually configured by the user to meet the user's personalized preference settings.

[0019] Optionally, since the second detection distance is a closer detection distance, when the first perception result indicates that it is within the area of ​​the second detection distance, the result indicates that there is an object moving at a distance closer to the terminal device. For this reason, the first perception result can be used to trigger a change in the energy consumption state of the first module, and can respond quickly to the movement of objects within the closer distance (for example, quickly run / wake up the first module) in order to improve the user experience.

[0020] In a possible implementation of the first aspect, the second perception result is used to control the energy consumption state of the first module in the terminal device, including: when the second perception result indicates that there is an object moving within the area within the third detection distance, the second perception result is used to control the first module in the terminal device to switch from a lower energy consumption state to a higher energy consumption state.

[0021] Optionally, the magnitude relationship between any one of the first detection distance and the second detection distance and the third detection distance is not limited. For example, any one of the distances may be greater than or equal to the third detection distance, or any one of the distances may be less than the third detection distance.

[0022] Based on the above technical solution, the reflected signal of the higher-frequency third signal can be used to determine the second perception result. Moreover, when the second perception result indicates that an object is moving within the area of ​​the third detection distance, the terminal device can determine that the first module is likely to be awakened or operated. Accordingly, the terminal device can control the first module in the terminal device to switch from a lower energy consumption state to a higher energy consumption state based on the second perception result. Generally, the energy consumption state of a module is positively correlated with the performance of the module. Therefore, the first module can provide a better user experience by operating in the higher energy consumption state.

[0023] In a possible implementation of the first aspect, the second perception result is used to control the energy consumption state of the first module in the terminal device, including: when the second perception result indicates that there is no object movement in the area within the fourth detection distance, the second perception result is used to control the first module in the terminal device to switch from a higher energy consumption state to a lower energy consumption state.

[0024] Optionally, the magnitude relationship between any one of the first detection distance and the second detection distance and the fourth detection distance is not limited. For example, any one of the distances may be greater than or equal to the fourth detection distance, or any one of the distances may be less than the fourth detection distance.

[0025] Based on the above technical solution, the reflected signal of the higher-frequency third signal can be used to determine a second perception result. Moreover, if the second perception result indicates that an object is moving within the area within the fourth detection range, the terminal device can determine that the first module is likely not to be awakened or operated. Accordingly, based on the second perception result, the terminal device can control the first module in the terminal device to switch from a higher energy consumption state to a lower energy consumption state to reduce energy consumption.

[0026] In a possible implementation of the first aspect, the first module is a display screen module; the high energy consumption state is a screen-on state and the low energy consumption state is a screen-off state.

[0027] Optionally, the first module is a display screen module; accordingly, the high-energy consumption state of the first module is a high-performance state and the low-energy consumption state of the first module is a low-performance state, for example, the high-performance state is a higher brightness state, a higher resolution state, and a non-standby state; the low-performance state is a lower brightness state, a lower resolution state, a standby state, etc.

[0028] Based on the above technical solution, the display screen module can provide user information in visual forms such as images and text. Accordingly, when the first module is a display screen module, by controlling the first module to switch from the screen-on state to the screen-off state, power consumption can be reduced. The device can also switch to the screen-off state after the human body moves a long distance away from the terminal device, thereby preventing privacy leakage. In addition, by controlling the first module to switch from the screen-off state to the screen-on state, the device can switch to the screen-on state after the human body moves a short distance away from the terminal device, thereby enabling a quick response and improving the user experience.

[0029] In a possible implementation manner of the first aspect, the first signal, the second signal, the third signal, and the fourth signal are acoustic wave signals or electromagnetic wave signals.

[0030] Based on the above technical solution, each signal can be implemented in a variety of ways to improve the flexibility of the solution implementation.

[0031] Optionally, when at least one of the above signals is a sound wave signal, the signal can be sent and received through the speaker and microphone of the terminal device. Compared with the signal transmission and reception process implemented by devices such as cameras and time of flight (ToF) sensors, since it does not involve image information, privacy leakage can be avoided and the deployment cost of the solution can be reduced.

[0032] In a possible implementation of the first aspect, the method also includes: the terminal device obtains operating information of a second module, and the second module is used for signal input of the terminal device; wherein the operating information of the second module and the second perception result are used to control the energy consumption state of the first module.

[0033] Based on the above technical solution, the terminal device can also obtain the operating information of the second module used for signal input of the terminal device, and control the energy consumption status of the first module based on the operating information of the second module. Combined with the operating information, the success rate of perception detection can be improved, avoiding false triggering of signals and resulting in a decline in user experience.

[0034] In a possible implementation manner of the first aspect, the method further includes: the terminal device sending the second perception result.

[0035] Based on the above technical solution, in a scenario where the first module is externally connected to or independent of the terminal device, the terminal device can also send the second perception result, so that the recipient of the second perception result can control the energy consumption status of the first module based on the second perception result to adapt to the scenario.

[0036] In a possible implementation manner of the first aspect, the method further includes: the terminal device controlling the energy consumption state of the first module based on the second perception result.

[0037] Based on the above technical solution, in the scenario where the first module is integrated into the terminal device (or the first module is an internal module of the terminal device), the terminal device can locally control the energy consumption state of the first module based on the second perception result to adapt to the scenario.

[0038] In a possible implementation of the first aspect, the terminal device sends a first signal, including: the terminal device sends a fifth signal, the sending frequency of the first signal is higher than the sending frequency of the fifth signal; the terminal device receives a sixth signal, the sixth signal includes a reflected signal of the fifth signal, and the sixth signal is used to determine a third perception result; the terminal device sends the first signal based on the third perception result.

[0039] Based on the above technical solution, the terminal device can also trigger the sending of the first signal with a lower frequency based on the sending of the fifth signal with a lower frequency. In this way, the terminal device can trigger the sending of the first signal with a lower frequency based on the perception result of the fifth signal with a lower frequency, which can further reduce the power consumption of the device.

[0040] In a possible implementation of the first aspect, the terminal device sends the first signal based on the third perception result, including: when the third perception result satisfies at least one of the following items, the terminal device sends the first signal, including: the third perception result indicates that there is object movement within the area of ​​the fifth detection distance; the third perception result indicates that there is object movement within the area of ​​the fifth detection distance and outside the area of ​​the sixth detection distance, and the fifth detection distance is greater than the sixth detection distance.

[0041] Based on the above technical solution, when at least one of the above items is met, the terminal device can determine that the third perception result indicates that there is an object moving in a certain area, so that the terminal device can trigger the sending of a first signal with a lower frequency, so that the energy consumption state of the first module can be controlled subsequently through the perception result indicated by the reflected signal of the first signal with a lower frequency.

It is understandable that the system architecture described in the embodiments of the present application is for the purpose of more clearly illustrating the technical solution of the embodiments of the present application and does not constitute a limitation on the technical solution provided in the embodiments of the present application.

[0072] Please refer to FIG1 , which is a schematic diagram of a terminal device 100 provided in this application.

[0073] The terminal device 100 may include at least one of a mobile phone, a foldable electronic device, a tablet computer, a desktop computer, a laptop computer, a handheld computer, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a cellular phone, a personal digital assistant (PDA), an augmented reality (AR) device, a virtual reality (VR) device, an artificial intelligence (AI) device, a wearable device, an in-vehicle device, a smart home device, or a smart city device. The embodiments of the present application do not impose any particular restrictions on the specific type of the terminal device 100.

[0074] The terminal device 100 may include one or more processors 110 and one or more signal transceiver modules controlled by the one or more processors 110 .

[0075] As an example of a signal transceiver module, the signal transceiver module is used to send wireless communication signals and receive wireless communication signals. For example, the signal transceiver module may include the wireless communication module 111 in Figure 1. The wireless communication signal may include but is not limited to wireless local area networks (WLAN) (such as wireless fidelity (Wi-Fi) networks), Bluetooth (BT), Bluetooth low energy (BLE), ultra wide band (UWB), global navigation satellite system (GNSS), frequency modulation (FM), near field communication technology (NFC), infrared technology (IR), and other wireless communication signals.

[0076] As another example of a signal transceiver module, the signal transceiver module is used to send and receive sound wave signals. For example, the signal transceiver module may include the speaker module 113 for sending sound wave signals and the microphone module 112 for receiving sound wave signals in FIG1 . The sound wave signals may include ultrasonic signals (e.g., sound wave signals with a signal frequency band of 18k-22k), and other low-frequency or high-frequency non-ultrasonic signals (e.g., sound wave signals with a signal frequency band of 6k-10k).

[0077] As another example of a signal transceiver module, the signal transceiver module is used to receive image signals. In this case, the signal transceiver module may be a signal receiving module. For example, the signal receiving module may include the camera module 114 for receiving image signals in FIG. 1 .

[0078] As another example of a signal transceiver module, the signal transceiver module is used to send and receive optical signals (such as infrared light signals or laser signals, etc.). For example, the signal transceiver module may include the Tof sensor module 115 for sending acoustic wave signals in FIG. 1 .

[0079] Optionally, the terminal device 100 may further include other modules, such as a display screen 116. The display screen 116 may be an internal module of the terminal device 100 or an external module of the terminal device 100, which is not limited here.

[0080] Generally speaking, a terminal device is a hardware device used to implement functions such as human-computer interaction and data input and output. Terminal devices can have different forms and functions in different application scenarios. In recent years, to enhance user experience, terminal devices have developed towards providing larger screens and more functions.

[0081] However, due to the increasing size of terminal screens and the increasing number of functional modules within terminal devices, the power consumption of terminal devices is increasing. Therefore, how to reduce the energy consumption of terminal devices is an urgent problem to be solved.

[0082] In one possible implementation, since the power consumption of the display screen accounts for a relatively high proportion, the terminal device may reduce power consumption by intelligently controlling the display screen.

[0083] For example, as shown in FIG2 , taking a desktop computer as an example, the terminal device can collect image signals or light signals through a camera or a Tof sensor (such as the camera module 114 or the Tof sensor module 115 shown in FIG1 ), and analyze the detection results through the signals. For example, the detection results can be used to indicate whether there is a person near the device, as well as the person's dynamic trends. Thereafter, if the detection result indicates that there is no person near the device or that someone is away from the device, the terminal device can control the display screen to turn off based on the detection result to save power consumption.

[0084] However, in the implementation process shown in Figure 2, since the camera and TOF sensor solutions involve the collection of image signals or light signals, this information may involve the user's privacy and bring the risk of privacy leakage.

[0085] In addition, some terminal devices may not have devices such as cameras and TOF sensors, which requires the addition of these devices, which are expensive. Therefore, how to optimize the energy-saving solution of terminal devices is a technical problem that needs to be solved urgently.

[0086] In order to solve the above problems, the present application provides a signal processing method and related equipment, which will be described in detail below with reference to the accompanying drawings.

[0087] Please refer to FIG3 , which is a schematic diagram of a signal processing method provided in this application. The method includes the following steps.

[0088] It should be noted that the following method can be executed by a terminal device or by an internal module of the terminal device. For example, the internal module can be a chip, a chip system, a processor, a logic module or software.

[0089] S301. The terminal device sends a first signal.

[0090] S302. The terminal device receives a second signal, wherein the second signal includes a reflected signal of the first signal and is used to determine the first sensing result.

[0091] S303. The terminal device sends a third signal based on the first perception result.

[0092] S304. The terminal device receives a fourth signal, wherein the fourth signal includes a reflection signal of the third signal, and the fourth signal is used to determine a second sensing result, wherein the second sensing result is used to control the energy consumption state of the first module.

[0093] In this application, terminal devices may include mobile phones, all-in-one computers, notebooks, tablets, etc. In different fields or scenarios, terminal devices may have different descriptions, for example, the terminal device may be replaced with other descriptions, such as electronic equipment, terminal, etc.

[0094] In this application, the transmission frequency of a signal may indicate the frequency at which the signal is transmitted within a certain time period. For example, if the transmission frequency of the third signal is higher than the transmission frequency of the first signal, it can be understood that the transmission frequency of the third signal is higher than the transmission frequency of the first signal within a certain time period (e.g., 1 second, 1 millisecond, etc.).

[0095] It should be understood that a reflected signal of a signal (e.g., a reflected signal of a first signal) can be understood as a reflected signal of the signal transmitted by a signal transmitting device, which is formed after the signal is transmitted by the signal transmitting device and collides with various objects in physical space (e.g., at least one of reflection, diffraction, or scattering) and reaches the signal transmitting device. Accordingly, the reflected signal can be used to determine a perception result, which can be understood as the reflected signal being used to perceive (or reflect) one or more of: information about the object in physical space or information about the movement of the object in physical space (e.g., human movement).

[0096] Optionally, in addition to the reflected signal formed by the signal colliding with an obstacle, the reflected signal of a signal may also include other signals, such as a direct signal formed by the signal passing between the signal transmitting device and the signal receiving device without being reflected by an obstacle, a signal generated by the communication process of other devices in the physical space, etc. Among them, the other signals can be regarded as reflected signals.

[0097] Optionally, the reflected signal can be replaced by other terms, such as echo signal, sensory feedback signal, sensory response signal, detection signal, sensory signal, etc.

[0098] It should be understood that the first module may be an energy-consuming module inside the terminal device, such as a display screen module inside the terminal device, a camera module inside the terminal device, etc. Alternatively, the first module may be an energy-consuming module external to the terminal device, such as a display device external to the terminal device, a camera module external to the terminal device, etc.

[0099] In one possible implementation, the process of the terminal device sending the third signal based on the first perception result in step S303 includes: when the first perception result satisfies at least one of the following methods A and B, the terminal device sends the third signal.

[0100] Method A: The first sensing result indicates that an object is moving within the area of ​​the first detection distance.

[0101] Mode B: The first sensing result indicates that an object is moving within the area of ​​the first detection distance and outside the area of ​​the second detection distance, and the first detection distance is greater than the second detection distance.

[0102] Specifically, when at least one of the above items is met, the terminal device can determine that the first perception result indicates that there is object movement in a certain area, so that the terminal device can trigger the sending of a third signal with a higher frequency, so that the movement of the object can be perceived subsequently through the reflected signal of the third signal with a higher frequency.

[0103] Optionally, the detection distance involved in the present application (for example, the first detection distance, the second detection distance, the third detection distance described later, the fourth detection distance, etc.) can be a pre-configured parameter (for example, the device is configured at the factory), or the detection distance can be a parameter manually configured by the user (for example, the detection distance can be a sparser signal manually configured by the user to further reduce power consumption; for example, the detection distance can be a denser signal manually configured by the user to improve the detection success rate) to meet the user's personalized preference settings.

[0104] Optionally, in mode B, since the first detection distance is a longer detection distance, when the first perception result indicates that the device is outside the area of ​​the first detection distance, the result indicates that an object is moving at a distance farther from the terminal device, that is, it is possible that the object's movement is caused by the human body being away from the terminal device. To this end, the first perception result can be used to trigger a change in the energy consumption state of the first module (that is, trigger the first module to switch from a higher power consumption state to a lower power consumption state), and can quickly respond to the movement of the object at the longer distance (for example, quickly run / wake up the first module) to reduce power consumption.

[0105] Optionally, in method B, since the second detection distance is a shorter detection distance, when the first perception result indicates that the device is within the area of ​​the second detection distance, the result indicates that an object is moving at a distance closer to the terminal device, that is, it is possible that the object's movement is caused by a human body approaching the terminal device, or it is possible that the human body is near the terminal device. To this end, the first perception result can be used to trigger a change in the energy consumption state of the first module (that is, trigger the first module to switch from a lower power consumption state to a higher power consumption state), and can quickly respond to the movement of objects within the shorter distance (for example, quickly run / wake up the first module) in order to improve the user experience.

[0106] In a possible implementation of the method shown in FIG3 , the first module is a display screen module; the high-energy consumption state is a screen-on state and the low-energy consumption state is a screen-off state. Specifically, the display screen module can provide user information in visual forms such as images and texts; accordingly, in the case where the first module is a display screen module, by controlling the first module to switch from a screen-on state to a screen-off state, power consumption can be reduced while also being able to switch to a screen-off state after the human body moves a large distance away from the terminal device, thereby avoiding privacy leakage. In addition, by controlling the first module to switch from a screen-off state to a screen-on state, it can be switched to a screen-on state after the human body moves a short distance closer to the terminal device, thereby enabling a quick response to enhance the user experience.

[0107] Optionally, the first module is a display screen module; accordingly, the high-energy consumption state of the first module is a high-performance state and the low-energy consumption state of the first module is a low-performance state, for example, the high-performance state is a higher brightness state, a higher resolution state, and a non-standby state; the low-performance state is a lower brightness state, a lower resolution state, a standby state, etc.

[0108] In one possible implementation, the second perception result received by the terminal device in step S304 can be used to control the energy consumption state of the first module in the terminal device. This control method may have multiple implementations, which will be described below with reference to some implementation examples.

[0109] Implementation example 1: When the second perception result indicates that there is an object moving in the area located at the third detection distance, the second perception result is used to control the first module in the terminal device to switch from a lower energy consumption state to a higher energy consumption state.

[0110] In implementation example 1, the reflected signal of the higher-frequency third signal can be used to determine a second perception result. Furthermore, when the second perception result indicates that an object is moving within the area of ​​the third detection distance, the terminal device can determine that the first module is likely to be awakened or operated. Accordingly, based on the second perception result, the terminal device can control the first module in the terminal device to switch from a lower energy consumption state to a higher energy consumption state. Generally, the energy consumption state of a module is positively correlated with the performance of the module. Therefore, the first module can provide a better user experience by operating in the higher energy consumption state.

[0111] Optionally, the magnitude relationship between any one of the first detection distance and the second detection distance and the third detection distance is not limited. For example, any one of the distances may be greater than or equal to the third detection distance, or any one of the distances may be less than the third detection distance.

[0112] As an application example of implementing Example 1, as shown in FIG4 , a terminal device is taken as a desktop computer. The initial state of the terminal device may be a screen-off state (i.e., a low-power state). In this initial state, the terminal device may send a first signal of a lower frequency in step S301 and receive a second signal containing a reflected signal of the first signal in step S302. In the case of "a person approaching" (i.e., someone approaching the terminal device), the first perception result determined by the second signal indicates that an object is moving; thereafter, the terminal device may send a third signal of a higher frequency based on the first perception result in step S303 and receive a fourth signal containing a reflected signal of the third signal in step S304. Thereafter, the second perception result determined by the fourth signal indicates that an object is approaching the terminal device, and the terminal device may trigger the display screen to switch from the initial state of the screen-off to the triggered state of the screen-on (i.e., control the display screen module to switch from a lower energy consumption state to a higher energy consumption state). In this way, the display screen module can provide a better user experience by operating in this higher energy consumption state.

[0113] Implementation example two: when the second perception result indicates that there is no object movement in the area located at the fourth detection distance, the second perception result is used to control the first module in the terminal device to switch from a higher energy consumption state to a lower energy consumption state.

[0114] In implementation example 2, the reflected signal of the higher-frequency third signal can be used to determine a second perception result. Furthermore, if the second perception result indicates that an object is moving within the area within the fourth detection range, the terminal device can determine that the first module is unlikely to be awakened or operated. Accordingly, based on the second perception result, the terminal device can control the first module in the terminal device to switch from a higher energy consumption state to a lower energy consumption state to reduce energy consumption.

[0115] Optionally, the magnitude relationship between any one of the first detection distance and the second detection distance and the fourth detection distance is not limited. For example, any one of the first detection distance and the second detection distance may be greater than or equal to the fourth detection distance, or any one of the first detection distance and the second detection distance may be less than the fourth detection distance.

[0116] As an application example of implementing Example 2, as shown in FIG5 , the terminal device is taken as a desktop computer. The initial state of the terminal device may be a screen-on state (i.e., a high power consumption state). In this initial state, the terminal device may send a first signal of a lower frequency in step S301 and receive a second signal containing a reflected signal of the first signal in step S302. In the case of “people moving away” (i.e., someone moving away from the terminal device), the first perception result determined by the second signal indicates that an object is moving; thereafter, the terminal device may send a third signal of a higher frequency based on the first perception result in step S303 and receive a fourth signal containing a reflected signal of the third signal in step S304. Thereafter, the second perception result determined by the fourth signal indicates that an object is moving away from the terminal device, and the terminal device may trigger the display screen to switch from the initial state of screen-on to the triggered state of screen-off (i.e., control the display screen module to switch from a higher energy consumption state to a lower energy consumption state). In this way, the display screen module can reduce the power consumption of the device without affecting the user experience by operating in this lower energy consumption state.

[0117] Based on the technical solution shown in Figure 3, the terminal device can trigger the transmission of a third signal with a higher transmission frequency based on the first perception result indicated by the reflected signal of the first signal with a lower transmission frequency. The second perception result indicated by the reflected signal of the third signal with a higher transmission frequency can be used to control the energy consumption state of the first module. Thus, while the accuracy of perception detection can be improved by using high-frequency signals, the high-frequency signals can also be triggered by the perception results of low-frequency signals to reduce device power consumption.

[0118] In addition, if perception detection is performed only through signals of a single frequency, signal parsing errors may occur due to the presence of interference signals in the physical space. Consequently, the terminal device may frequently trigger changes in the energy consumption state of the first module based on this error, which can easily cause damage to the first module due to frequent energy consumption changes. In the above technical solution, the process of triggering high-frequency signals through the perception results of low-frequency signals can, to a certain extent, avoid signal parsing errors caused by signals of a single frequency, thereby reducing the probability of damage to the first module due to frequent energy consumption changes.

[0119] In a possible implementation of the method shown in Figure 3, the first signal, the second signal, the third signal, and the fourth signal are acoustic signals or electromagnetic signals. Thus, each signal can be implemented in a variety of ways to enhance the flexibility of the solution implementation.

[0120] Optionally, when at least one of the above signals is a sound wave signal, the signal can be sent and received through the speaker and microphone of the terminal device. Compared with the signal transmission and reception process implemented by devices such as cameras and time of flight (ToF) sensors, since it does not involve image information, privacy leakage can be avoided and the deployment cost of the solution can be reduced.

[0121] Optionally, when at least one of the above signals is a sound wave signal, the terminal device may not execute the method of Figure 3 when the device plays an audio file. In this way, the perception process achieved through the sound wave signal can be avoided from affecting the playback process of the audio file.

[0122] In one possible implementation of the method shown in FIG3 , the method further includes: the terminal device obtaining operating information of a second module, the second module being used for signal input to the terminal device; wherein the operating information of the second module and the second perception result are used to control the energy consumption state of the first module. Specifically, the terminal device may also obtain operating information of the second module used for signal input to the terminal device, and control the energy consumption state of the first module based on the operating information of the second module. Combining this operating information can improve the success rate of perception detection and avoid false triggering of signals that may lead to a decline in user experience.

[0123] In one possible implementation of the method shown in FIG3 , after step S304, the method further includes: the terminal device transmitting the second perception result. Specifically, in a scenario where the first module is externally connected to or independent of the terminal device, the terminal device may further transmit the second perception result, so that a recipient of the second perception result can control the energy consumption state of the first module based on the second perception result to adapt to the scenario.

[0124] In one possible implementation of the method shown in FIG3 , after step S304, the method further includes: the terminal device controlling the energy consumption state of the first module based on the second perception result. Specifically, in a scenario where the first module is integrated into the terminal device (or the first module is an internal module of the terminal device), the terminal device can locally control the energy consumption state of the first module based on the second perception result to adapt to the scenario.

[0125] In one possible implementation of the method shown in FIG3 , before step S301, the method further includes: the terminal device transmitting a fifth signal, wherein the first signal is transmitted at a higher frequency than the fifth signal; and the terminal device receiving a sixth signal, wherein the sixth signal includes a reflected signal of the fifth signal, and the sixth signal is used to determine a third perception result. Thereafter, in step S301, the terminal device transmits the first signal based on the third perception result.

[0126] Specifically, the terminal device can also trigger the sending of the first signal with a lower frequency based on the sending of the fifth signal with a lower frequency. In this way, the terminal device can trigger the sending of the first signal with a lower frequency based on the perception result of the fifth signal with a lower frequency, which can further reduce the power consumption of the device.

[0127] Optionally, the terminal device sends the first signal based on the third perception result, including: when the third perception result satisfies at least one of the following methods 1 and 2, the terminal device sends the first signal.

[0128] Method 1: The third perception result indicates that there is an object moving within the area within the fifth detection distance.

[0129] Method 2: The third perception result indicates that there is an object moving within the area of ​​the fifth detection distance and outside the area of ​​the sixth detection distance, and the fifth detection distance is greater than the sixth detection distance.

[0130] Optionally, in method 2, since the sixth detection distance is a closer detection distance, when the third perception result indicates that it is within the area of ​​the sixth detection distance, the result indicates that there is an object moving at a distance closer to the terminal device. For this reason, the third perception result can be used to trigger a change in the energy consumption state of the first module, and can quickly respond to the movement of objects within the closer distance (for example, quickly run / wake up the first module) in order to improve the user experience.

[0131] Thus, when at least one of the above items is met, the terminal device can determine that the third perception result indicates that there is object movement in a certain area, so that the terminal device can trigger the sending of a first signal with a lower frequency, so that the energy consumption state of the first module can be controlled subsequently through the perception result indicated by the reflected signal of the first signal with a lower frequency.
