[0023] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. However, it should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present disclosure. In the following detailed description, for ease of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present disclosure. However, it is apparent that one or more embodiments may also be implemented without these specific details. In addition, in the following description, descriptions of known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present disclosure.

[0024] The terms used herein are only for describing specific embodiments and are not intended to limit the present disclosure. The terms "comprise", "include", etc. used herein indicate the existence of features, steps, operations and / or components, but do not exclude the existence or addition of one or more other features, steps, operations or components.

[0025] All terms (including technical and scientific terms) used herein have the meanings commonly understood by those skilled in the art unless otherwise defined. It should be noted that the terms used herein should be interpreted as having a meaning consistent with the context of this specification and should not be interpreted in an idealized or overly rigid manner.

[0026] When using expressions such as "at least one of A, B, and C, etc.", they should generally be interpreted according to the meaning of the expression commonly understood by those skilled in the art (for example, "a system having at least one of A, B, and C" should include but is not limited to a system having A alone, B alone, C alone, A and B, A and C, B and C, and / or A, B, C, etc.).

[0027] The embodiments of the present disclosure provide a control method and an electronic device. Before introducing the technical solutions provided by the embodiments of the present disclosure, the related technologies involved in the present disclosure are first described.

[0028] In the relevant technology, the relevant regulations point out that the impact of electromagnetic radiation on the human body must meet safety standards before it can be put into use, referred to as SAR. The full name of SAR in English is Specific Absorption Rate, which is generally called electromagnetic wave absorption ratio or specific absorption rate in Chinese. It is the electromagnetic wave energy absorption ratio of mobile phones and other wireless products. SAR is defined as: under the action of an external electromagnetic field, an induced electromagnetic field will be generated in the human body. Since various organs of the human body are lossy media, the electromagnetic field in the body will generate current, resulting in the absorption and dissipation of electromagnetic energy. SAR is often used in biodosimetry to characterize this physical process. The meaning of SAR is the electromagnetic power absorbed or consumed by unit mass of human tissue, and the unit is W / kg.

[0029] Therefore, for wireless devices, the transmission power must be reduced to meet the SAR test requirements and achieve human safety needs.

[0030] With the evolution of wireless communication devices represented by smartphones, the impact of electromagnetic radiation generated during the use of devices on human health has also attracted widespread public attention. In order to ensure the safe operation of wireless communication devices and safeguard the vital interests of the majority of users.

[0031] For example, by deploying a SAR sensor in an electronic device, the SAR sensor is placed near the antenna to detect whether a human body is close to adjust the power of the electronic device, thereby reducing the absorption of electromagnetic energy by the human body. This method not only requires additional hardware costs, for example, the equipment cost may increase by about 1-2 US dollars, but the SAR sensor also requires more space in the electronic device, affecting the layout of the antenna.

[0032] For example, the wireless network card in the electronic device can be used to force the transmission power to be reduced to the standard value to ensure that the SAR test can be passed under any circumstances. However, since the transmission power of the wireless network card is always in a forced reduction state, when the human body is far away from the laptop, it will affect the wireless performance and transmission distance of the electronic device.

[0033] Before further describing the embodiments of the present disclosure in detail, the nouns and terms involved in the embodiments of the present disclosure are described. The nouns and terms involved in the embodiments of the present disclosure are subject to the following interpretations.

[0034] CSI (Channel State Information), or channel state information, refers to information that describes the characteristics of a wireless channel (such as fading, noise, path loss, etc.). In short, CSI reflects the propagation characteristics of a transmitted signal from the transmitter to the receiver. CSI includes: amplitude information and phase information. Amplitude information describes changes in signal strength due to multipath effects, attenuation, and other factors during signal propagation; phase information describes phase changes during signal propagation, which is usually related to different paths and interference effects of signal arrival.

[0035] Ultra-Wideband (UWB) technology is a wireless communication technology, usually used for short-distance, high-speed data transmission. It is characterized by the use of a very wide spectrum (generally covering the frequency band of 3.1GHz to 10.6GHz), which has a much larger bandwidth than traditional wireless communication technologies (such as WiFi or Bluetooth).

[0036] In wireless communications, each data packet usually consists of a header and a body. The header contains some important information about the data packet, such as the source address, destination address, protocol type, and specific fields for channel assessment (such as HT-LTF).

[0037] The embodiment of the present disclosure provides a control method, including: monitoring environmental data of the space environment in which the electronic device is located; when the environmental data indicates that the relative position between the target object and the electronic device has changed, adjusting the working parameters of the wireless communication module of the electronic device to target working parameters corresponding to the changed target relative position; wherein the power consumption of the wireless communication module is different under different working parameters. By real-time monitoring of the relative position of the target object and the electronic device in the environment surrounding the electronic device, according to the change of the relative position between the target object and the electronic device, the working parameters of the wireless communication module of the electronic device are adaptively adjusted in real time, so that the working parameters of the wireless communication module of the electronic device can meet the human body's needs for electromagnetic energy safety and ensure good wireless performance of the electronic device in different states (i.e., the target object and the electronic device are in different relative positions).

[0038] The following will be passed Figure 1~Figure 2 The control method of the disclosed embodiment is described in detail.

[0039] Figure 1 The flowchart of the control method according to the embodiment of the present disclosure is schematically shown.

[0040] like Figure 1 As shown, the control method of this embodiment includes operations S210 to S220.

[0041] In operation S210, environmental data of a spatial environment in which the electronic device is located is monitored.

[0042] Exemplarily, the electronic device may be a terminal with wireless communication function. An electronic device is a device capable of transmitting and receiving wireless signals, and can exchange network data, voice or video information through radio waves (such as radio frequency signals). Unlike traditional wired communication devices, wireless communication devices do not rely on physically connected cables or lines, but communicate through radio spectrum (for example, WiFi, Bluetooth, cellular network, etc.). For example, the electronic device may be a laptop, Bluetooth speaker, router, smart TV, etc.

[0043] Environmental data can be environmental information around the electronic device. Environmental information can be environmental data composed of human bodies, animals, objects, removable devices, etc., such as the distance between the user and the laptop; it can also be temperature, humidity, electromagnetic radiation, etc., such as the ambient temperature is 28 degrees Celsius; it can also be the impact of objects on the electronic device, such as the user's hand blocking the position of the electronic device's camera.

[0044] The environment around the electronic device can be monitored through the electronic device's own camera, and can also be monitored through the electronic device's sound sensor, infrared sensor, magnetic field sensor, etc. In other examples, the controller or driver of the wireless communication module of the electronic device can also monitor the surrounding environmental data through signal strength changes or WiFiSensing positioning technology. The environment around the electronic device can also be monitored by combining a camera with a sensor. In other embodiments, the environment around the electronic device can also be monitored by a monitoring device (for example, a camera) that is relatively independent of the electronic device but can communicate.

[0045] For example, taking the electronic device as a laptop computer, the camera on the laptop computer can be used to capture images of the environment around the electronic device in real time to analyze whether the user of the electronic device is close to the laptop computer or whether the user is far away from the laptop computer.

[0046] In operation S220, when the relative position between the target object and the electronic device represented by the environmental data changes, the operating parameters of the wireless communication module of the electronic device are adjusted to target operating parameters corresponding to the changed relative position of the target object;

[0047] Among them, the power consumption of the wireless communication module is different under different working parameters.

[0048] Exemplarily, the target object may be a human body, an animal, a movable device, etc. For example, when the target object is a movable device, the target object may be a robot, a sweeping robot, a drone, etc.

[0049] The change in the relative position between the target object and the electronic device may be that the relative position between the target object and the electronic device changes. For example, the target object may be close to the electronic device, or the target object may be far away from the electronic device. For example, a user walks in front of a laptop, or the user moves away from the laptop. Or, the user moves close to or away from a router.

[0050] The wireless communication module may be a component that realizes wireless data transmission between electronic devices. For example, the wireless communication module may be a WiFi module, a Bluetooth module, a GPRS module, etc.

[0051] The working parameters of the wireless communication module can be the signal transmission power, transceiver frequency, channel / frequency band, etc. For example, the transmission power of the WiFi module can be 20~30dBm, the transceiver frequency can be a low-frequency signal (such as 30MHz to 1GHz range) or a high-frequency signal (such as 2.4GHz or higher frequency), and the transceiver frequency band can include 2.4G or 5G, etc. When the wireless communication module category is different, the corresponding transmission power, transceiver frequency, channel / frequency band is also different. The corresponding parameters can be adjusted according to the transmission power, transceiver frequency, channel / frequency band, etc. corresponding to the category of the wireless communication module.

[0052] Among them, different working parameters of wireless communication modules have different effects on the power consumption of electronic devices. For example, in the same environment, 2.4G WiFi consumes less power than 5G WiFi. In the same environment, low-power Bluetooth modules consume less power than high-power Bluetooth modules.

[0053] The target operating parameter may be a parameter that does not exceed the maximum value of the operating parameter of the wireless communication module corresponding to the relative position of the target. For example, when the distance between the electronic device and the human body is 1-5cm, the electromagnetic radiation generated by the device is required to be less than 2W / kg. When the user is 5cm away from the computer, the transmission power of the WiFi module is reduced to reduce the electromagnetic radiation generated by the computer to less than 2W / kg. The transmission power can correspond to multiple values, as long as the electromagnetic radiation generated by the computer is less than 2W / kg at this power.

[0054] For example, taking the electronic device as a laptop computer, the camera on the laptop computer can be used to capture images of the surrounding environment of the electronic device in real time. The current laptop computer transmits power and generates electromagnetic radiation of 3W / kg at a distance of 5cm. When the user is detected to be close to the laptop computer, and the user is less than 5cm away from the computer, the transmit power of the WiFi module can be reduced to reduce the electromagnetic radiation generated by the computer to below 2W / kg to achieve a safe range of electromagnetic energy absorption by the human body. When the user is detected to be away from the laptop computer, and the user gradually moves away from the computer, and the user is 100cm away from the computer, the transmit power of the WiFi module can be increased. At this time, the human body is not affected by electromagnetic radiation, and the transmit power of the WiFi module can be increased to the maximum value to maintain good wireless communication performance of the electronic device.

[0055] Taking the electronic device as a router as an example, the environment around the router can be detected by the WiFi module on the router. When the WiFi repeater is close to the router, it means that the signal quality of the current wireless communication of the router is poor. The transmission power and / or radiation frequency of the wireless communication module of the router can be increased, and the frequency band of the signal can be reduced to improve the transmission quality and transmission intensity of the wireless signal. It can be understood that by real-time monitoring of the relative position of the target object and the electronic device in the environment around the electronic device, according to the change of the relative position between the target object and the electronic device, the working parameters of the wireless communication module of the electronic device are adaptively adjusted in real time, so that the working parameters of the wireless communication module of the electronic device can meet the human body's needs for electromagnetic energy safety in different states (that is, the target object and the electronic device are in different relative positions) and can also ensure the good wireless performance of the electronic device. As mentioned above, in operation S210, the environmental data of the spatial environment in which the electronic device is located is monitored. In a feasible manner, the operation can further include operation S211a.

[0056] In operation S211a, the motion data of the target object in the space environment is monitored using the wireless communication module of the electronic device.

[0057] For example, when the target object enters the target range of the electronic device, the wireless communication module can be used to monitor the motion data of the target object. For example, when the human body is within 100 cm from the electronic device, the distance detection between the human body and the electronic device is turned on. Here, the target range can be adjusted according to actual needs.

[0058] The wireless communication module may be a WiFi module, a Bluetooth module, a UWB module or a mobile communication module, etc. The wireless signal received and sent by the wireless communication module may be used to determine whether the human body is close to or far away from the electronic device.

[0059] Since obstacles, scattering of wireless signals, and fading of wireless signals will affect the channel state information during wireless signal transmission, and the energy of wireless signals will also decay as the propagation distance increases. In addition, the dielectric constants of the human body or other media (for example, dogs, robots) are different, which will cause different degrees of frequency shift or absorption of electromagnetic waves, resulting in changes in channel state information. For conductors such as metals, electromagnetic waves will be reflected or shielded, and even the resonance characteristics of the antenna will be destroyed, which may cause greater changes in the channel state. Therefore, based on the different effects of the human body and different objects on electromagnetic waves, the degree of change in the channel state information is also different, which can be used as a basis for judging whether the human body is close to or far away from the electronic device.

[0060] For example, the channel state information in the WLAN protocol can be used to determine whether the human body is close to or far away from the electronic device. In the OFDM-MIMO system, CSI information is used to monitor the surrounding environment. Signal state information can be obtained by sending fixed symbols of the HT-LTF (HighThroughputLongTrainingfield) field in the header of the data packet, so as to perform channel evaluation and detect multipath channel changes, which may include amplitude attenuation and phase offset in the spatial domain, frequency domain and time domain. For example, the wireless network card PHY module can be responsible for obtaining CSI information from the wireless data packet of the physical layer. The processing of CSI information is mainly based on Modeling-Based Algorithms, that is, the CSI information when the human body approaches the antenna is known, and the current CSI is judged. If the received CSI information conforms to the known CSI information of approaching, it can be judged whether there is a human body close to the electronic device. If the received CSI information conforms to the known CSI information of being far away, it can be judged whether there is a human body far away from the electronic device.

[0061] If the received data packets are sent from antennas of different devices, the CSI can be extracted periodically, for example, every 200ms. If they are sent from another antenna of the same device, there can be a polling cycle, for example, every 200ms. Here, there is no specific limit on the cycle for extracting channel state information, and the cycle time can be adjusted according to actual needs.

[0062] Multiple first channel state information corresponding to the human body at different positions from the electronic device can be measured in advance for different wireless communication modules. During the use of the electronic device, when the second channel state information of the human body approaching the electronic device is detected, the second channel state information is compared with the known multiple first channel state information to obtain the distance information of the human body from the electronic device. When the distance information at multiple consecutive moments gradually decreases, it can be obtained that the human body is gradually approaching the electronic device. For example, the distance changes from 50cm to 5cm. The transmission power of the wireless communication module can be reduced (for example, from 30dBm to 20dBm), the radiation frequency (for example, from 20GHz to 15GHz), or the signal frequency band (for example, from 2.4G to 5G band), etc., so that the electromagnetic radiation generated by the electronic device is within a safe range when the human body approaches the electronic device. When the distance information at multiple consecutive moments gradually increases, it can be obtained that the human body is gradually moving away from the electronic device, and the distance changes from 5cm to 100cm. The transmission power of the wireless communication module can be increased (for example, from 20dBm to 30dBm), the radiation frequency (for example, from 15GHz to 20GHz), or the signal frequency band can be reduced (for example, from 5G to 2.4G band), so as to maintain good communication performance of the wireless communication module when the human body is far away from the electronic device. Among them, the dielectric constants of different objects can be used to obtain information on whether various objects are close to or far away from the electronic device, as well as the distance between the object and the electronic device.

[0063] It can be understood that without increasing the system cost, the distance detection between the target object and the electronic device can be achieved by only using the existing wireless communication module of the device, so as to adjust the transmission power of the electronic device according to the distance, thereby meeting the SAR requirements when the distance is short, or ensuring good communication performance when the distance is far.

[0064] As described above, in operation S210, the environmental data of the space environment where the electronic device is located is monitored. In another implementation, the operation may further include operation S211b.

[0065] In operation S211b, the environment change data in the space environment is monitored using a target sensor of the electronic device.

[0066] Exemplarily, the target sensor may be a camera, a sound sensor, an infrared sensor, a magnetic field sensor, etc.

[0067] For example, a camera in an electronic device is turned on, an image is captured by the camera, and a position analysis is performed on the captured target object in the image to determine whether a human body / object / animal is close to the electronic device, or to determine whether a human body / object / animal is far away from the electronic device.

[0068] As described above, in operation S210, the environmental data of the space environment in which the electronic device is located is monitored. In yet another possible implementation, the operation may further include operation S211c.

[0069] In operation S211c, the wireless communication module and the target sensor of the electronic device are used to monitor the environmental change data in the space environment.

[0070] Exemplarily, it is possible to determine whether a human body is close to the electronic device, or to determine whether a human body is far away from the electronic device, by combining the wireless communication module with the target sensor. In the case where the wireless communication module is not accurate enough in detecting the target object, further confirmation can be performed through the target sensor. For example, in the case where the wireless communication module cannot confirm that the target object is a human body (for example, an object with a conductivity close to that of a human body), the target sensor can be used to further determine that the target object is a human body.

[0071] Alternatively, the positioning method of the wireless communication module and the sensor signal of the target sensor may be used simultaneously, such as using the WiFi Sensing positioning technology of the WiFi module and the image data monitored by the image sensor to comprehensively judge the relative position change between the human body and the router or laptop computer, and then determine whether the human body is close to or far away from the router or laptop computer.

[0072] For example, the WiFi module of an electronic device receives and sends wireless signals to obtain channel status information. If a human body is suspected to be approaching the electronic device based on the channel status information, the camera of the electronic device can be activated to capture and analyze images to further confirm whether a human body is approaching / moving away from the electronic device.

[0073] It is understandable that, on the basis of the wireless communication module, adding detection of the target sensor can enhance the accuracy of the electronic device's judgment on whether the target object is close to or far away from the electronic device.

[0074] As described above, in operation S220, when the relative position between the target object and the electronic device represented by the environmental data changes, the operating parameters of the wireless communication module of the electronic device are adjusted to the target operating parameters corresponding to the changed target relative position. In an achievable manner, the operation may further include operation S221a.

[0075] In operation S221a, when environmental data indicates that the distance between the target object and the electronic device changes from a first distance range to a second distance range, the transmission power of the wireless communication module is adjusted from the first transmission power to the second transmission power, and / or the radiation frequency of the wireless communication module is adjusted from the first radiation frequency to the second radiation frequency, wherein the first distance range is greater than the second distance range, the first transmission power is greater than the second transmission power, and the first radiation frequency is greater than the second radiation frequency.

[0076] Exemplarily, when the target object is close to the electronic device and the electromagnetic radiation intensity of the electronic device needs to be reduced, if the electronic device monitors the target object close to the electronic device through the wireless communication module and / or the target sensor, the transmission power and / or radiation frequency of the wireless communication module are reduced to reduce the electromagnetic radiation intensity of the electronic device. Here, the transmission power of the wireless communication module can be adjusted, the radiation frequency can be adjusted, and the transmission power and radiation frequency of the wireless communication module can be adjusted at the same time to meet the demand for reducing the radiation intensity of the electronic device.

[0077] For example, when a person is close to a laptop, the laptop's electromagnetic radiation intensity needs to be reduced to ensure that the impact of electromagnetic radiation on the human body is in a safe state. If the laptop detects through the WiFi module that a person changes from 100cm away from the laptop to 5cm away from the electronic device, it means that the person is gradually approaching the laptop. At this time, the transmission power of the WiFi module can be adjusted from 30dBm to 20dBm, so that the laptop's electromagnetic radiation intensity is less than 2W / kg at 5cm, reducing the impact of electromagnetic radiation on the human body and keeping the human body in a safe state.

[0078] In other embodiments, when the environmental data indicates that the distance between the target object and the electronic device changes from the first distance range to the second distance range, the signal frequency band of the wireless communication module is adjusted from the first signal frequency band to the second signal frequency band, and the second signal frequency band is greater than the first signal frequency band. Alternatively, the signal frequency band of the wireless communication module is adjusted from the second signal frequency band to the first signal frequency band, the transmission power of the wireless communication module is adjusted from the first transmission power to the second transmission power, and the radiation frequency of the wireless communication module is adjusted from the first radiation frequency to the second radiation frequency.

[0079] As described above, in operation S220, when the relative position between the target object and the electronic device represented by the environmental data changes, the operating parameters of the wireless communication module of the electronic device are adjusted to the target operating parameters corresponding to the changed target relative position. In an achievable manner, the operation may further include operation S221b.

[0080] In operation S221b, when environmental data indicates that the distance between the target object and the electronic device changes from a second distance range to a first distance range, the transmission power of the wireless communication module is adjusted from the second transmission power to the first transmission power, wherein the first distance range is greater than the second distance range, and the first transmission power is greater than the second transmission power.

[0081] Exemplarily, when the target object is far away from the electronic device and the communication performance of the electronic device needs to be improved, if the electronic device monitors that the target object is far away from the electronic device through the wireless communication module and / or the target sensor, the transmission power and / or radiation frequency of the wireless communication module are increased to improve the communication performance of the electronic device, so as to meet the requirement that the location far away from the electronic device can also have good signal quality and signal strength. Here, the transmission power of the wireless communication module can be adjusted, the radiation frequency can be adjusted, the signal frequency band can be adjusted, and a combination of the transmission power, radiation frequency and signal frequency band of the wireless communication module can be selected to meet the good communication performance of the electronic device.

[0082] For example, when a person is far away from a router, the communication performance of the electronic device needs to be improved. If the router detects through the WiFi module that a person is moving from 5cm to 100cm away from the router, it means that the person is gradually moving away from the router. At this time, the transmission power of the WiFi module can be adjusted from 20dBm to 30dBm to enhance the communication performance of the router at 100cm. At this time, the electromagnetic radiation intensity of the electronic device at a distance of 100cm from the electronic device may increase from the original 0.5W / kg to 2W / kg, but it can also keep the human body in a safe state.

[0083] As described above, in operation S220, when the relative position between the target object and the electronic device represented by the environmental data changes, the operating parameters of the wireless communication module of the electronic device are adjusted to the target operating parameters corresponding to the changed target relative position. In an achievable manner, the operation may further include operation S221c.

[0084] In operation S221c, when environmental data indicates that the distance between the target object and the electronic device changes from a first distance range to a third distance range, the transmission power of the wireless communication module is adjusted from the first transmission power to the third transmission power, wherein the first distance range is smaller than the third distance range, and the first transmission power is smaller than the third transmission power.

[0085] Exemplarily, when the target object is further away from the electronic device, in order to ensure the signal strength of the signal quality of the wireless signal, it is necessary to further improve the communication performance of the electronic device. If the electronic device monitors through the wireless communication module and / or the target sensor that the target object is further away from the electronic device, the transmission power and / or radiation frequency of the wireless communication module can be increased to improve the communication performance of the electronic device to meet the requirements of having better signal quality and signal strength at a location farther away from the electronic device. Here, the transmission power of the wireless communication module can be adjusted, the radiation frequency can be adjusted, the signal frequency band can be adjusted, and a combination of the transmission power, radiation frequency and signal frequency band of the wireless communication module can be selected to meet the good communication performance of the electronic device.

[0086] For example, when the human body is far away from the router, the communication performance of the electronic device needs to be improved. If the router monitors through the WiFi module that a human body changes from 100cm away from the router to 200cm away from the router, it means that the human body is further away from the router. At this time, the transmission power of the WiFi module can be adjusted from 30dBm to 40dBm to enhance the communication performance of the router at 200cm. As the distance between the human body and the router increases, the electromagnetic radiation intensity of the router at 200cm is less than 2W / kg, which can keep the human body in a safe state.

[0087] As described above, in operation S220, when the relative position between the target object and the electronic device represented by the environmental data changes, the operating parameters of the wireless communication module of the electronic device are adjusted to target operating parameters corresponding to the changed target relative position. In an achievable manner, the operation may further include operation S221d.

[0088] In operation S221d, when the environmental data indicates that the distance between the target object and the electronic device changes from a third distance range to a fourth distance range, the transmission power of the wireless communication module is adjusted from the third transmission power to the fourth transmission power, wherein the third distance range is smaller than the fourth distance range and the third transmission power is greater than the fourth transmission power.

[0089] Exemplarily, as the target object gradually moves away from the electronic device, when the distance between the target object and the electronic device exceeds a preset range threshold, the transmission power and / or radiation frequency of the wireless communication module can be reduced to save the power consumption of the electronic device. If the electronic device monitors through the wireless communication module and / or the target sensor that the target object is away from the electronic device beyond the preset range threshold, the transmission power and / or radiation frequency of the wireless communication module can be reduced to save the power consumption of the electronic device. Here, the transmission power of the wireless communication module can be adjusted, the radiation frequency can be adjusted, the signal frequency band can be adjusted, and a combination of the transmission power, radiation frequency and signal frequency band of the wireless communication module can be selected to save the power consumption of the electronic device.

[0090] For example, the preset range threshold may be that the distance between the target object and the electronic device exceeds 500 cm. Here, the fourth distance range may be understood as being greater than or equal to the preset range threshold. It should be noted that the embodiment of the present disclosure does not specifically limit the setting of the preset range threshold, and the size of the fourth distance range may be determined according to the actual application of the electronic device and the type of the electronic device.

[0091] For example, the preset range threshold of the router may be 500cm, and the preset range threshold of the router may be understood as the optimal signal coverage range of the router. When the human body gradually moves away from the router, if the distance between the human body and the router exceeds 500cm, the transmission power and / or radiation frequency of the WiFi module may be reduced to save the power consumption of the router. If the router monitors through the WiFi module that a human body changes from 200cm away from the router to 600cm away from the router, which exceeds the preset range threshold of the router, the transmission power of the WiFi module may be adjusted from 40dBm to 30dBm to save the power consumption of the router. As the distance between the human body and the router increases, the electromagnetic radiation intensity of the router to the human body is less than 2W / kg, which can keep the human body in a safe state.

[0092] Figure 2 The second flowchart of the control method according to the embodiment of the present disclosure is schematically shown.

[0093] As described above, in operation S220, when the relative position between the target object and the electronic device represented by the environmental data changes, the operating parameters of the wireless communication module of the electronic device are adjusted to the target operating parameters corresponding to the changed target relative position. Figure 2 As shown, the operation may further include operation S310 to operation S320.

[0094] In operation S310, attribute information of a target object is obtained.

[0095] In operation S320, the operating parameters of the wireless communication module are adjusted based on the attribute information and the position change data of the target object relative to the electronic device.

[0096] Exemplarily, the attribute information may be category information of the target object. For example, when the target object is a human body, the attribute information may be a person, when the target object is a cat, the attribute information may be an animal, and when the target object is a sweeping robot, the attribute information may be a movable device.

[0097] In the case where the attribute information of the target object is different, as the relative position between the target object and the electronic device changes, the working parameters of the wireless communication module are adjusted differently. For the same electronic device, for the same target object, when the distance of the target object relative to the electronic device changes differently (for example, close to the electronic device or far away from the electronic device), the working parameters of the wireless communication module may be adjusted differently. For the same electronic device, for different target objects, when the distance of the target object relative to the electronic device changes in the same way (for example, close to the electronic device), the working parameters of the wireless communication module may also be adjusted differently.

[0098] For example, when the target object is a human body and the electronic device is a router, if the human body is close to the router, it is necessary to reduce the transmission power and / or radiation frequency of the wireless communication module of the router, and the frequency band of the signal can also be increased to reduce the electromagnetic radiation intensity of the router to meet the needs of human safety. If the human body is far away from the router, it is necessary to increase the transmission power and / or radiation frequency of the wireless communication module of the router, and the frequency band of the signal can also be reduced to ensure good communication performance at a distance from the router, which not only meets the needs of the human body's safety state, but also meets the needs of users for good communication. When the target object is a sweeping robot and the electronic device is a router, if the sweeping robot is close to the router, it is necessary to increase the transmission power and / or radiation frequency of the wireless communication module of the router, and the frequency band of the signal can also be reduced to improve the communication performance of the router, so that the communication performance of the sweeping robot is better.

[0099] As described above, in operation S320, the operating parameters of the wireless communication module are adjusted based on the attribute information and the position change information of the target object relative to the electronic device. In one achievable manner, the operation may further include operation S321a.

[0100] In operation S321a, when the attribute information indicates that the target object is a relay device for relaying wireless communication signals, the operating parameters of the wireless communication module are adjusted using a first adjustment strategy based on the location change data.

[0101] For example, a relay device is a device used to relay (forward) wireless communication signals (network signals), which can extend signal coverage, enhance signal quality, and increase network capacity in wireless communication systems. In simple terms, the role of a relay device is to receive signals from a source device (such as a router or base station) and retransmit the signal to a target device, usually in a place where the original signal cannot effectively reach. For example, WiFi repeaters, cellular communication relay devices, etc.

[0102] The first adjustment strategy may be a method for adjusting the transmission power / radiation frequency / signal frequency band of the wireless communication module corresponding to the distance of the relay device approaching or moving away from the electronic device. When the relay device is close to the electronic device, it indicates that the signal quality of the current wireless communication is poor. The transmission power and / or radiation frequency of the wireless communication module may be increased, and the frequency band of the signal may also be reduced.

[0103] For example, when a WiFi repeater is close to a router, it means that the signal quality of the current wireless communication of the router is poor. The transmission power and / or radiation frequency of the wireless communication module of the router can be increased, and the frequency band of the signal can be reduced to improve the transmission quality and transmission strength of the wireless signal.

[0104] As described above, in operation S320, the operating parameters of the wireless communication module are adjusted based on the attribute information and the position change information of the target object relative to the electronic device. In one achievable manner, the operation may further include operation S321b.

[0105] In operation S321b, when the attribute information indicates that the target object is a mobile communication device, the operating parameters of the wireless communication module are adjusted using a second adjustment strategy based on the location change data.

[0106] By way of example, the mobile communication device may be a notebook computer, an electronic pet, or the like.

[0107] The second adjustment strategy may be a method for adjusting the transmission power / radiation frequency / signal frequency band of the wireless communication module corresponding to the distance between the mobile communication device and the electronic device. When the mobile communication device is close to the electronic device, it indicates that the signal quality of the current wireless communication is poor. The transmission power and / or radiation frequency of the wireless communication module may be increased, and the frequency band of the signal may also be reduced.

[0108] For example, when a laptop is close to a router, it means that the signal quality of the current router wireless communication is poor. The transmission power and / or radiation frequency of the wireless communication module of the router can be increased, and the frequency band of the signal can be reduced to improve the transmission quality and transmission strength of the wireless signal.

[0109] As described above, in operation S320, the operating parameters of the wireless communication module are adjusted based on the attribute information and the position change information of the target object relative to the electronic device. In one achievable manner, the operation may further include operation S321c.

[0110] In operation S321c, when the attribute information indicates that the target object is a person or a pet, the operating parameters of the wireless communication module are adjusted using a third adjustment strategy based on the position change data.

[0111] Exemplarily, the third adjustment strategy may be a method for adjusting the transmission power / radiation frequency / signal frequency band of the corresponding wireless communication module when a person or pet approaches or moves away from the electronic device. Since it is necessary to meet the impact of electromagnetic radiation on the human body or pet, the human body or pet is in a safe state. When a person or pet approaches an electronic device, the transmission power and / or radiation frequency of the wireless communication module can be reduced, and the frequency band of the signal can be increased to reduce the electromagnetic radiation intensity of the electronic device, so that the human body or pet is in a safe state.

[0112] For example, when a person or pet is close to a laptop computer, the transmission power and / or radiation frequency of the laptop computer's WiFi module can be reduced, and the signal frequency band can be increased to reduce the electromagnetic radiation intensity of the laptop computer, keeping the person or pet in a safe state.

[0113] It should be noted that, under different adjustment strategies, the parameter types of the adjusted working parameters of the wireless communication module are the same or different.

[0114] Different adjustment strategies are used for target objects with different properties. For example, when the target object is a relay device, and the relay device is close to the electronic device, the transmission power and / or radiation frequency of the electronic device can be increased, and the frequency band of the signal can be reduced to improve the signal quality. When the target object is a person, and the person is close to the electronic device, the transmission power and / or radiation frequency of the electronic device can be reduced, and the frequency band of the signal can be increased to reduce the electromagnetic radiation intensity of the electronic device and keep the human body in a safe state.

[0115] As described above, in operation 321a, the operating parameters of the wireless communication module are adjusted using the first adjustment strategy based on the location change data. In one achievable manner, the operation may further include operation S3211a.

[0116] In operation S3211a, when the position change data indicates that the relay device changes from the fifth distance range to the sixth distance range relative to the electronic device, the transmission power of the wireless communication module is adjusted from the fifth transmission power to the sixth transmission power, wherein the fifth distance range is smaller than the sixth distance range and the fifth transmission power is smaller than the sixth transmission power.

[0117] Exemplarily, when the relay device is far away from the electronic device, it is necessary to enhance the signal quality of wireless communication to ensure that the relay device has good communication performance even when it is far away. The transmission power and / or radiation frequency of the wireless communication module can be increased, and the frequency band of the signal can be reduced.

[0118] For example, when the WiFi repeater is far away from the router, the signal quality of the router's wireless communication may deteriorate as the distance increases. At this time, the transmission power (from 20dBm to 30dBm) and / or radiation frequency (such as 15GHz to 20GHz) of the router's wireless communication module can be increased, and the signal frequency band can also be reduced (for example, from 5G to 2.4G) to improve the transmission quality and transmission strength of the wireless signal.

[0119] As described above, in operation 321a, the operating parameters of the wireless communication module are adjusted using the first adjustment strategy based on the location change data. In another achievable manner, the operation may further include operation S3211b.

[0120] In operation S3211b, when the position change data indicates that the relay device changes from the fifth distance range to the seventh distance range relative to the electronic device, the signal frequency band of the wireless communication module is adjusted from the first signal frequency band to the second signal frequency band, wherein the fifth distance range is greater than the seventh distance range and the first signal frequency band is less than the second signal frequency band.

[0121] For example, when the signal quality of wireless communication is strong, if the relay device is close to the electronic device, the transmission power and / or radiation frequency of the wireless communication module can be reduced, and the frequency band of the signal can also be reduced.

[0122] For example, when the WiFi repeater is close to the router, the transmission power (from 30dBm to 20dBm) and / or radiation frequency (such as 20GHz to 15GHz) of the wireless communication module of the router can be reduced, and the frequency band of the signal can also be reduced (for example, from 2.4G to 5G band).

[0123] Figure 3 One of the schematic diagrams schematically illustrates the application of the control method according to the embodiment of the present disclosure; Figure 4 The second schematic diagram schematically shows the application of the control method according to the embodiment of the present disclosure.

[0124] The embodiment of the present disclosure further provides a control method, and the control method of this embodiment includes operation S410 to operation S420.

[0125] In operation S410, wireless communication data of a wireless communication module of an electronic device is monitored.

[0126] Exemplarily, the wireless communication data may be channel state information or communication transmission parameters, and the communication transmission parameters may be signal-to-noise ratio, signal strength, delay, etc.

[0127] In operation S420, when the wireless communication data indicates that the target object moves from the first distance range to the second distance range relative to the electronic device, the transmission power of the wireless communication module is controlled to be adjusted from the first transmission power to the second transmission power.

[0128] Among them, the first distance range is greater than the second distance range, the first transmission power is greater than the second transmission power, and the first radiation frequency is greater than the second radiation frequency.

[0129] For example, refer to Figure 3 and Figure 4 , the antenna 1 of the electronic device acts as a transmitter to transmit the signal, the signal is transmitted in space, and the antenna 2 acts as a receiver to receive the signal. The signal will be affected by obstacles during the transmission in space. At the same time, the signal will be scattered and faded during the transmission in space, which will affect the state of the channel and change the parameters of communication transmission. Therefore, by analyzing the channel state or the parameters of communication transmission, it is possible to determine whether a target object is close to or far away from the electronic device.

[0130] For example, during the use of a laptop computer, when the channel state information of a human body approaching the laptop computer is detected, the channel state information is compared with a plurality of known channel state information (which can be determined in advance), so as to obtain the distance information of the human body from the laptop computer. When the distance information gradually decreases at multiple consecutive moments, it can be obtained that the human body is gradually approaching the laptop computer, and the distance changes from 50 cm to 5 cm. The transmission power of the WiFi module can be reduced so that the electromagnetic radiation generated by the laptop computer is within a safe range when the human body approaches the laptop computer. When the distance information gradually increases at multiple consecutive moments, it can be obtained that the human body is gradually moving away from the laptop computer, and the distance changes from 5 cm to 100 cm. The transmission power of the WiFi module can be increased so as to maintain good communication performance of the WiFi module (at a position far away from the laptop computer) when the human body is away from the laptop computer. Among them, it can be obtained whether various objects are close to or away from electronic devices, as well as the distance information between objects and electronic devices according to the dielectric constants of different objects.

[0131] Wireless communication data can be obtained by the following methods: when the electronic device transmits data frequently, it can be obtained by using the existing data transmission data packets; or when the amount of transmitted data is small, it can be obtained by actively sending data packets. The actively sent data packets here can be empty data packets.

[0132] Currently, Intel can use WiFi network technology (WiFi Sensing) to determine whether someone is approaching the computer, and it can achieve an error rate of less than 1%. However, the embodiment of the present disclosure obtains wireless communication data by sending data packets, and determines whether there is a target object approaching / moving away from the electronic device, which can further reduce the error rate compared to WiFi network technology. Intel's WiFi Sensing polling time is 200ms. For scenarios with a throughput greater than 1Gbps, the impact on WiFi performance during operation can cause the performance to drop by 6%. For scenarios with a throughput less than 1Gbps, the impact on WiFi performance during operation can be ignored. However, the embodiment of the present disclosure obtains wireless communication data by sending data packets. For throughputs of different sizes, the impact on the communication performance of the WiFi module can be ignored.

[0133] The disclosed embodiment analyzes the wireless communication data to determine whether the target object is close to or far away from the electronic device. The increase in power consumption is in the order of several milliwatts, with reference to Intel's WiFiSensing, which increases power consumption by 5.5 mW.

[0134] As described above, in other embodiments, in operation S420, when the wireless communication data indicates that the target object moves from a first distance range to a second distance range relative to the electronic device, the radiation frequency of the wireless communication module is controlled to adjust from the first radiation frequency to the second radiation frequency.

[0135] For example, when a laptop is in use, when the channel state information of a human body approaching the laptop is detected, the channel state information is compared with a plurality of known channel state information (which can be measured in advance), thereby obtaining the distance information of the human body from the laptop. When the distance information gradually decreases at multiple consecutive moments, it can be obtained that the human body is gradually approaching the laptop, and the distance changes from 50cm to 5cm. The radiation frequency of the WiFi module can be reduced so that the electromagnetic radiation generated by the laptop is within a safe range when the human body approaches the laptop. When the distance information gradually increases at multiple consecutive moments, it can be obtained that the human body is gradually moving away from the laptop, and the distance changes from 5cm to 100cm. The radiation frequency of the WiFi module can be increased so that when the human body is away from the laptop, the WiFi module maintains good communication performance (at a distance far from the laptop).

[0136] Taking a router as an example, the environment around the router can be detected through the WiFi module on the router. When the WiFi repeater is close to the router, it means that the signal quality of the current wireless communication of the router is poor. The radiation frequency of the wireless communication module of the router can be increased to improve the transmission quality and transmission strength of the wireless signal.

[0137] As described above, in some further embodiments, operation S420, when the wireless communication data represents that the target object moves from a first distance range to a second distance range relative to the electronic device, controls the signal frequency band of the wireless communication module to be adjusted from the third signal frequency band to the fourth signal frequency band, and the third signal frequency band is smaller than the fourth signal frequency band.

[0138] For example, when a laptop is in use, when the channel state information of a human body approaching the laptop is detected, the channel state information is compared with a plurality of known channel state information (which can be determined in advance), so as to obtain the distance information of the human body from the laptop. When the distance information gradually decreases at multiple consecutive moments, it can be obtained that the human body is gradually approaching the laptop, and the distance changes from 50cm to 5cm. The signal frequency band of the WiFi module can be reduced (for example, adjusted from 2.4G to 5G frequency band) so that the electromagnetic radiation generated by the laptop is within a safe range when the human body approaches the laptop. When the distance information gradually increases at multiple consecutive moments, it can be obtained that the human body is gradually moving away from the laptop, and the distance changes from 5cm to 100cm. The signal frequency band of the WiFi module can be increased (for example, adjusted from 5G to 2.4G frequency band) so as to maintain good communication performance of the WiFi module (at a distance far from the laptop) when the human body is away from the laptop.

[0139] Taking the router as an example, the environment around the router can be detected through the WiFi module on the router. When the WiFi repeater is close to the router, it means that the signal quality of the current wireless communication of the router is poor. The frequency band of the signal of the wireless communication module of the router can be reduced to improve the transmission quality and transmission strength of the wireless signal.

[0140] In other embodiments, when the wireless communication data indicates that the target object moves from a first distance range to a second distance range relative to the electronic device, a plurality of combinations of the transmission power, radiation frequency and signal frequency band of the wireless communication module can be selected to reduce the radiation intensity of the electronic device.

[0141] As described above, the control method of the embodiment of the present disclosure further includes: obtaining a monitoring image of the spatial environment in which the electronic device is located, and monitoring the position change of the target object relative to the electronic device based on the monitoring image and the wireless communication data.

[0142] For example, taking the electronic device as a laptop computer, the WiFi module of the laptop computer receives and sends wireless signals to obtain channel status information. When it is found that a human body is suspected to be approaching the laptop computer based on the channel status information, the camera of the laptop computer can be activated to capture and analyze images to further confirm whether a human body is approaching / moving away from the electronic device.

[0143] As described above, the control method of the embodiment of the present disclosure also includes: obtaining monitoring images and / or wireless communication data through target drive processing to adjust at least one of the transmission power, radiation frequency, and signal frequency band of the wireless communication module based on the processing results.

[0144] For example, if we continue to use a laptop as an electronic device, the laptop's WiFi module receives and sends wireless signals to obtain channel status information. When the WiFi driver analyzes the channel status information and finds that a person is suspected of approaching the laptop, it can start the laptop's camera to capture and analyze images to further confirm whether a person is approaching / moving away from the laptop. The camera feeds back the confirmation information (a person is approaching the laptop) to the laptop and sends it to the WiFi driver, which sends a signal to reduce the WiFi module's transmission power and / or radiation frequency, or increase the signal frequency band.

[0145] It is also possible to capture and analyze images only through the camera of the laptop to confirm whether a human body is approaching / moving away from the laptop; or it is also possible to confirm whether a human body is approaching / moving away from the laptop only by analyzing the channel status information.

[0146] Based on the above control method, the present disclosure also provides an electronic device. Figure 5A-5B The device is described in detail.

[0147] Figure 5A One of the schematic diagrams of an electronic device according to an embodiment of the present disclosure is schematically shown; Figure 5B A second schematic diagram of an electronic device according to an embodiment of the present disclosure is schematically shown.

[0148] like Figure 5A As shown, the electronic device 100 of this embodiment includes a wireless communication module 101 and a controller 102 connected to the wireless communication module signal.

[0149] In one possible implementation, the controller parses the wireless communication data and controls the transmission power of the wireless communication module to adjust from the first transmission power to the second transmission power when it is determined that the target object moves from the first distance range to the second distance range relative to the electronic device. The first distance range is greater than the second distance range, and the first transmission power is greater than the second transmission power.

[0150] In another possible implementation, the controller parses the wireless communication data and controls the radiation frequency of the wireless communication module to adjust from the first radiation frequency to the second radiation frequency when determining that the target object moves from the first distance range to the second distance range relative to the electronic device. The first radiation frequency is greater than the second radiation frequency.

[0151] In another possible implementation, the controller parses the wireless communication data and controls the signal frequency band of the wireless communication module to adjust from the third signal frequency band to the fourth signal frequency band when determining that the target object moves from the first distance range to the second distance range relative to the electronic device. The third signal frequency band is smaller than the fourth signal frequency band.

[0152] In other embodiments, when it is determined that the target object moves from the first distance range to the second distance range relative to the electronic device, the controller controls the wireless communication module to select a combination of multiple modes of the transmission power, radiation frequency and signal frequency band of the wireless communication module to reduce the radiation intensity of the electronic device. When it is determined that the target object moves from the first distance range to the second distance range relative to the electronic device, the transmission power of the wireless communication module can be reduced, the radiation frequency of the wireless communication module can be reduced, or the signal frequency band can be increased. For details, please refer to the above operation S420, which will not be repeated here.

[0153] In other embodiments, when the distance range between the target object and the electronic device changes from the second distance range to the first distance range, the transmission power of the wireless communication module is adjusted from the second transmission power to the first transmission power, wherein the first distance range is greater than the second distance range, and the first transmission power is greater than the second transmission power.

[0154] For example, when the communication performance of an electronic device needs to be improved when the human body is far away from the router, if the router monitors through the WiFi module that a human body changes from 5 cm away from the router to 100 cm away from the router, it means that the human body is gradually moving away from the router. At this time, the controller can control the WiFi module to adjust the transmission power of the WiFi module from 20 dBm to 30 dBm, so that the communication performance of the router at 100 cm is enhanced. At this time, the electromagnetic radiation intensity of the electronic device at a distance of 100 cm from the electronic device may increase from the original 0.5 W / kg to 2 W / kg, but it can also keep the human body in a safe state.

[0155] In other embodiments, when the distance range between the target object and the electronic device changes from a first distance range to a third distance range, the transmission power of the wireless communication module is adjusted from the first transmission power to the third transmission power, wherein the first distance range is smaller than the third distance range, and the first transmission power is smaller than the third transmission power.

[0156] For example, when the human body is far away from the router, the communication performance of the electronic device needs to be improved. If the router monitors through the WiFi module that a human body changes from 100cm away from the router to 200cm away from the router, it means that the human body is further away from the router. At this time, the controller can control the WiFi module to adjust the transmission power of the WiFi module from 30dBm to 40dBm, so that the communication performance of the router at 200cm is enhanced. As the distance between the human body and the router increases, the electromagnetic radiation intensity of the router at 200cm is less than 2W / kg, which can keep the human body in a safe state.

[0157] In other embodiments, when the distance range between the target object and the electronic device changes from a third distance range to a fourth distance range, the transmission power of the wireless communication module is adjusted from the third transmission power to the fourth transmission power, wherein the third distance range is smaller than the fourth distance range, and the third transmission power is greater than the fourth transmission power.

[0158] For example, the fourth distance range here can be understood as being greater than or equal to a preset range threshold. The preset range threshold can be that the distance between the target object and the electronic device exceeds 500 cm. It should be noted that the embodiment of the present disclosure does not specifically limit the setting of the preset range threshold, and the size of the fourth distance range can be determined according to the actual application of the electronic device and the type of the electronic device.

[0159] For example, the preset range threshold of the router may be 500cm, and the preset range threshold of the router may be understood as the optimal signal coverage range of the router. When the human body gradually moves away from the router, if the distance between the human body and the router exceeds 500cm, the controller may control the WiFi module to reduce the transmission power and / or radiation frequency of the WiFi module to save the power consumption of the router. If the router monitors through the WiFi module that a human body changes from 200cm away from the router to 600cm away from the router, which exceeds the preset range threshold of the router, the controller may control the WiFi module to adjust the transmission power of the WiFi module from 40dBm to 30dBm to save the power consumption of the router. As the distance between the human body and the router increases, the electromagnetic radiation intensity of the router to the human body is less than 2W / kg, which can keep the human body in a safe state.

[0160] In some embodiments, the electronic device also includes a camera, which is used to obtain a monitoring image of the spatial environment in which the electronic device is located; the controller can monitor the position change of the target object relative to the electronic device based on the monitoring image and wireless communication data; wherein the controller includes a second driver for the camera and / or a first driver for the wireless communication module.

[0161] Reference Figure 5B, Continuing with the example of a laptop computer, the laptop computer's WiFi module receives and sends wireless signals to obtain channel status information. When the WiFi driver analyzes the channel status information and finds that a person is suspected of approaching the laptop computer, the controller can drive the second driver of the camera to start the camera to capture and analyze images, and further confirm whether a person is approaching / moving away from the laptop computer. The camera feeds back the confirmation information (a person is approaching the laptop computer) to the laptop computer and sends it to the WiFi driver, which sends a signal to reduce the WiFi module's transmission power and / or radiation frequency, or increase the signal frequency band.
