detailed description

Embodiments of embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout.

The embodiments described below by referring to the drawings are exemplary, are only for explaining the embodiments of the present invention, and should not be construed as limiting the embodiments of the present invention.

Referring to Fig. 1, the control method of the embodiment of the present invention includes:

Step S1, controlling the emission capacitance sensor to emit a detection signal.

In some embodiments, the control method of the embodiments of the present invention is applied to some electronic devices with wireless communication functions, such as mobile phones, and the electronic devices include capacitive sensors, which can be used to transmit detection signals.

When an electronic device communicates with other electronic devices that also have wireless communication functions, it will radiate or receive radio waves through the antenna. Radio waves may cause harm to the user's health, especially when the user is very close to the electronic device. However, the user may be very close to the electronic device due to usage habits or influenced by the current environment during use. Therefore, the control method in the embodiment of the present invention is required to overcome this problem.

Wherein, the harm of radio waves to user's health can be measured by electromagnetic wave energy absorption ratio (Specific Absorption Rate, SAR). SAR is the electromagnetic wave radiation energy absorbed by human tissue per unit mass and unit time, and the unit is W/kg. In some organizations and institutions, the SAR value is used as the standard for measuring radio wave radiation. To ensure human health, the SAR value should be less than a certain threshold.

Due to the near-field effect of mobile phone radiation, when the electronic device is far away from the human body, the radiation is not harmful to the human body. SAR will only become a significant problem when the human body is close enough to the electronic device, for example, when the user uses the electronic device to answer When a call comes in, keep your face close to the electronic device.

In the above scenario, the electronic device controls the transmitting capacitive sensor to transmit detection signals, and when the user is far away from the electronic device, all the transmitted detection signals will be received by the receiving capacitive sensor as return signals.

The transmitting capacitive sensor is coupled with the receiving capacitive sensor to form an electric field. When the hand or face of the human body enters the electric field, it will affect the coupling between the two capacitive sensors. Since the human body is equivalent to a conductor, the electric field between the two capacitive sensors will be partly Transferred to the human body and then poured into the earth, the change in field strength is equivalent to the change in capacitance.

Step S2, processing the return signal received by the receiving capacitive sensor coupled with the transmitting capacitive sensor and judging whether the intensity of the return signal is less than a predetermined value.

It can be known from step S1 that by detecting the return signal strength of the detection signal, the field strength change between the two capacitive sensors can be judged. The field strength change means that the user is close to the electronic device and has a part in the electric field.

It can be understood that as the position and time of the human body in the electric field change, for example, the user's face gradually approaches the electronic device until it contacts the electronic device, and the contact time gradually increases, the field strength will continue to change, and the received return signal The intensity also gradually decreases.

When the intensity of the return signal decreases to a predetermined value, it is considered that the radiation of the electronic device is harmful to the human body.

The preset value can be set based on the return signal strength corresponding to the SAR value standard formulated by relevant institutions or organizations, and calibrated before leaving the factory. When the user subsequently uses the electronic device, when the intensity of the returned signal is lower than a predetermined value, that is, the SAR value is greater than the standard value, it is considered that the radiation will affect human health.

Step S3, controlling the electronic device to reduce the transmitting power of the antenna when the strength of the returned signal is less than a predetermined value.

It can be seen from step S2 that if the strength of the returned signal is less than the predetermined value, the strong radiation will affect human health at this time, so the control electronic device reduces the transmission power of the antenna to reduce the radiation.

It can be understood that the reduction of the transmission power to a certain extent will not affect the performance of the antenna. And reducing the power should also be based on the premise of ensuring the performance of the antenna.

To sum up, in the control method of the embodiment of the present invention, when the electronic device is too close to the human face, it is considered that the antenna radiation of the electronic device causes greater damage to the user, so the strength of the returned signal is detected, and the strength of the returned signal mainly depends on The amount of detection signal absorbed by the face, in the case of a weak return signal, can be judged that the amount of radiation absorbed by the user is already large. Similarly, it can be judged that the antenna radiation of the user receiving the electronic device is large, and the antenna of the electronic device needs to be reduced. Transmitting power, so as to avoid users receiving strong radiation at close range and causing harm.

In some embodiments, an electronic device, such as a mobile phone, includes a housing that is substantially rectangular and includes a front side wall, a rear side wall, and left and right side walls connecting the front side wall and the rear side wall .

The hand grip sensor generally includes a plurality of capacitive sensors connected to its input pins, and the number of capacitive sensors is determined by the number of input pins of the hand grip sensor. It includes at least one transmitting capacitive sensor and one receiving capacitive sensor.

Since it is necessary to detect whether the user's face is close to the electronic device, the capacitive sensor should be kept away from the user's usual grip parts, such as the rear side wall of the electronic device, the lower part of the left side wall and the right side wall, thereby improving the accuracy of detection.

Since the hand-held sensor adopts an active self-capacitance sensor, that is, the capacitive characteristic change formed between the capacitive sensor and the face is used to judge the coupling state between the face and the electronic device, so the capacitive sensor should be set on the side wall made of insulator material the inner wall. For example, it is arranged on the upper part of the left side wall and the right side wall made of insulating material, or on the inner wall of the front side wall.

In some embodiments, the transmit capacitive sensor and the receive capacitive sensor are located near the upper portion of the electronic device. For example, it can be installed at the sensor integration place above the screen. Due to the spatial radiation of the capacitive sensor, there is no need to open additional holes on the front panel, and the detection signal can also be received by the user and form a return signal. At the same time, it is set on the top of the screen, so that the user's hands are not easy to touch. In this way, the success rate and accuracy of detecting the proximity of the face can be improved.

Please refer to Figure 2. In some embodiments, the hand-held sensor also includes a processing terminal for controlling the transmitting capacitance sensor and the receiving capacitance sensor. The processing terminal radiates a detection signal to space through the transmitting capacitance sensor, and the detection signal may have a certain period. A wave signal of a certain amplitude. For example, it could be a square wave signal. Before leaving the factory, set the square wave signal of the electronic device to control its period, amplitude and quantity. It can be understood that in such an embodiment, the return signal should also be a square wave signal.

The control method of this embodiment is basically the same as the above-mentioned embodiment, and its difference is:

Step S2': When the number of square waves included in the square wave signal in the return signal is less than the predetermined number, it is judged that the strength of the return signal is less than the predetermined value.

From the explanation of step S2 in the above embodiment, it can be known that the transmitted square wave signal used for detecting the signal is partially absorbed during the process of approaching the human face, so the number of square waves that can return to the return signal of the receiving capacitive sensor will be less than that of the transmitted signal. The number of square waves at .

When the intensity of the return signal is lower than the predetermined value, that is, when the number of square waves of the return signal is less than the predetermined value, it is considered that the radiation will affect human health. At this time, the control electronic device reduces the transmission power of the antenna to reduce the radiation.

In this way, the electronic device can detect the proximity of the human face by setting a hand-held capacitor to determine whether the human body is exposed to excessive radiation, and then control the electronic device to reduce the transmission power of the antenna.

Referring to Fig. 3, in some embodiments, the control method also includes:

Step S4, prompting the user to stay away from the electronic device.

It can be seen from step S2 or step S2' of the above-mentioned embodiment that when the intensity of the return signal is less than a predetermined value or the number of square waves of the return signal is less than a predetermined value, it is considered that the radiation of the electronic device is harmful to the human body. While the antenna is emitting power, the user is reminded to stay away from the electronic device.

The prompt signal may include vibration, buzzer or flash, which is realized by a rotor motor of the electronic device, a buzzer or a front breathing light.

It can be understood that the types of prompt information include but not limited to the manners disclosed in this implementation manner.

In this way, the user can be reminded to stay away when the radiation of the electronic device is high, thereby ensuring the safety of the user.

Please refer to FIG. 4 , the control device 10 according to the embodiment of the present invention is used to control the electronic device 20 .

The control device 10 includes a first control module 100 , a processing module 102 and a second control module 104 .

The first control module 100 is used for controlling the emission capacitance sensor 201 to emit detection signals.

The processing module 102 is used for processing the return signal received by the receiving capacitive sensor 202 coupled with the transmitting capacitive sensor 201 and judging whether the intensity of the return signal is less than a predetermined value.

The second control module 104 is connected with the processing module 102, and is used for controlling the electronic device 20 to reduce the transmission power of the antenna (not shown) when the strength of the return signal is less than a predetermined value.

The control device 10 in the embodiment of the present invention thinks that the antenna radiation of the electronic device 20 will cause greater damage to the user when the electronic device 20 is too close to the human face, so it detects the strength of the return signal, which mainly depends on the detection signal The amount absorbed by the face, in the case of weak return signal strength, can be judged that the amount of radiation absorbed by the user has been relatively large. Similarly, it can be judged that the antenna radiation of the user receiving the electronic device 20 is relatively large, and the power of the electronic device 20 needs to be reduced. The transmitting power of the antenna, so as to avoid the damage caused by the strong radiation received by the user at close range.

It should be noted that, the explanations of the implementation manners of the above-mentioned control method are also applicable to the control device 10 of this implementation manner, and will not be repeated here.

Please refer to FIG. 5 . In some embodiments, the electronic device 20 includes a hand sensor 200 , and the hand sensor 200 includes a transmitting capacitive sensor 201 and a receiving capacitive sensor 202 .

The hand grip sensor 200 also includes a processing terminal for controlling the transmitting capacitive sensor 201 and the receiving capacitive sensor 202 , which may be the first control module 100 , the processing module 102 and the second control module 104 .

In this way, the electronic device 20 can detect the proximity of a human face by setting the hand-held capacitor 200 to determine whether the human body is exposed to excessive radiation, and then control the electronic device 20 to reduce the transmission power of the antenna.

In some embodiments, the transmitting capacitive sensor 201 and the receiving capacitive sensor 202 are disposed close to the upper part of the electronic device 20 .

In this way, the success rate and accuracy of face approach detection can be improved.

In such an embodiment, the first control module 100 radiates a detection signal into space through the transmitting capacitive sensor 201 , and the detection signal may be a wave signal with a certain period and a certain amplitude. For example, it could be a square wave signal. Before leaving the factory, the square wave signal of the electronic device 20 is set to control its period, amplitude and quantity. It can be understood that in such an embodiment, the return signal should also be a square wave signal.

The control device 10' of the present embodiment is basically the same as the above-mentioned embodiment, and the difference lies in:

The processing module 102' judges that the strength of the returned signal is less than a predetermined value when the number of square waves contained in the square wave signal in the returned signal is less than a predetermined number.

The square wave signal emitted by the transmitting capacitive sensor 201 for detecting the signal is partially absorbed during the approaching process of the human face, so the number of square waves that can return the return signal of the receiving capacitive sensor 202 will be smaller than the number of square waves at the time of transmission.

When the strength of the return signal is lower than the predetermined value, that is, when the number of square waves of the return signal is less than the predetermined value, it is considered that the radiation will affect human health, and at this time the control electronic device 20 reduces the transmission power of the antenna to reduce the radiation.

Referring to FIG. 6 , in some implementations, the control device 10 further includes a prompt module 106 connected to the processing module 102 , and the prompt module 106 is configured to prompt the user to stay away from the electronic device 20 .

The prompt signal may include vibration, buzzer or flash, and it may be realized by a rotor motor of the electronic device 20, a buzzer or a front breathing light and the like.

In this way, the user can be reminded to stay away when the radiation of the electronic device 20 is high, so as to ensure the safety of the user.

It should be noted that, the explanations of the implementation manners of the above-mentioned control method are also applicable to the control device 10 of this implementation manner, and will not be repeated here.

Please refer to FIG. 7 , the electronic device 20 according to the embodiment of the present invention includes the control device 10 according to the above embodiment.

In some implementations, the electronic device 20 may be an electronic device with a communication function such as a mobile phone.

The electronic device 20 in the embodiment of the present invention includes the control device 10. Therefore, when the electronic device 20 is too close to the human face, it is considered that the antenna radiation of the electronic device 20 will cause greater damage to the user, so the intensity of the returned signal is detected, and the return The strength of the signal mainly depends on the amount of the detection signal absorbed by the face. In the case of a weak return signal, it can be judged that the amount of radiation absorbed by the user is already large. Similarly, it can be judged that the antenna radiation of the user receiving electronic device 20 is relatively large. Therefore, it is necessary to reduce the transmission power of the antenna of the electronic device 20, so as to prevent the user from receiving strong radiation at close range and causing harm.

It should be noted that the electronic device 20 in the embodiment of the present invention can be realized by the control method and the control device 10 in the above embodiment.
