The embodiment of the invention provides a proximity detection method and a terminal, wherein the terminal comprises a first screen, a second screen, a standing-wave ratio detection module and an infrared detection module arranged aiming at the first screen, and the method comprises the following steps: acquiring first intensity of an infrared signal detected by an infrared detection module; if the difference value between the first intensity and the preset intensity is smaller than or equal to a first threshold value, and the difference value between the current first standing-wave ratio and the second standing-wave ratio of the terminal antenna, detected by the standing-wave ratio detection module, is within a second preset range, determining that an object is close to the second screen; the preset intensity is the intensity of the infrared signal detected by the infrared detection module under the condition that no object is close to the first screen; the second standing wave ratio is a standing wave ratio of the antenna without an object being close to the first screen and the second screen. Through the scheme, under the condition that the second screen is not provided with the infrared detection module, the difference value between the first strength and the preset strength can be smaller than or equal to the first threshold value, and the difference value between the current first standing-wave ratio and the second standing-wave ratio of the terminal antenna is larger than or equal to the second threshold value, it can be determined that an object is close to the second screen, the second screen can be switched to the screen-saving state at the moment, so that the infrared detection modules are not required to be arranged on the two screens in the double-sided screen terminal, and the approach detection can be realized, so that the cost and the design complexity of the double-sided screen terminal can be reduced.
The terminal in the embodiment of the invention can be a mobile terminal or a non-mobile terminal. The mobile terminal may be a mobile phone, a tablet computer, a notebook computer, a palm computer, a vehicle-mounted terminal, a wearable device, an ultra-mobile personal computer (UMPC), a netbook, or a Personal Digital Assistant (PDA), etc.; the non-mobile terminal may be a Personal Computer (PC), a Television (TV), a teller machine, a self-service machine, or the like; the embodiments of the present invention are not particularly limited.
The execution subject of the approach detection method provided in the embodiment of the present invention may be the terminal (including a mobile terminal and a non-mobile terminal), or may also be a functional module and/or a functional entity capable of implementing the approach detection method in the terminal, which may be specifically determined according to actual use requirements, and the embodiment of the present invention is not limited. The following takes a terminal as an example to exemplarily explain the approach detection method provided by the embodiment of the present invention.
As shown in fig. 2, the approach detection method provided by the embodiment of the invention includes the following steps S11-S12.
S11, the terminal acquires the first intensity of the infrared signal detected by the infrared detection module.
The terminal in the embodiment of the invention is a double-sided screen terminal, and comprises a first screen, a second screen, a standing-wave ratio detection module and an infrared detection module which is arranged aiming at the first screen.
Optionally, the first screen and the second screen are respectively located on two faces of the terminal.
Optionally, in the embodiment of the present invention, the step S11 may be executed when the terminal establishes a call connection.
And S12, if the difference between the first intensity and the preset intensity is smaller than or equal to a first threshold value, and the difference between the current first standing-wave ratio and the second standing-wave ratio of the terminal antenna detected by the standing-wave ratio detection module is larger than or equal to a second threshold value, determining that an object is close to the second screen by the terminal.
Generally, the infrared detection module includes a transmitting tube and a receiving tube, the transmitting tube and the receiving tube can be respectively disposed on two opposite edges of a screen of the terminal, the transmitting tube is used for transmitting infrared signals, the receiving tube is used for receiving infrared signals, after a call is made (i.e., a call connection is established), the detection module starts to work, the transmitting tube continuously transmits infrared signals, and the corresponding receiving tube receives infrared signals.
In the embodiment of the invention, the intensity of the infrared signal detected by the infrared detection module is the intensity of the infrared signal received by the receiving tube.
Illustratively, as shown in fig. 3, the diagram is a schematic diagram of an infrared detection module, in fig. 3, 110 is a transmitting tube, 111 is a receiving tube, and 112 is a control module, which is configured to control the transmitting tube to transmit an infrared signal and control the receiving tube to receive the infrared signal.
The preset intensity may be the intensity of the infrared signal detected by the infrared detection module when no object is close to the first screen. In this case, the infrared signal emitted from the emitting tube of the infrared detection module is directly received by the receiving tube without being reflected.
If the difference between the first intensity and the preset intensity is smaller than or equal to the first threshold, it indicates that the infrared signal emitted by the emission tube may not be reflected, and at this time, it may be considered that no object is close to the first screen.
Alternatively, the antenna in the embodiment of the present invention may be an antenna located at an upper half portion of the terminal. Since the lower half of the terminal is shielded when the user holds the terminal, the antenna may be provided in a portion that is not shielded when the user holds the terminal, in order to eliminate the influence of the user holding the terminal on the standing-wave ratio of the antenna.
In general, the standing wave ratio of an antenna is a basic measure for the passive efficiency of the antenna. Wherein the second standing wave ratio is a standing wave ratio of the antenna under the condition that no object is close to the first screen and the second screen.
Illustratively, the first standing wave ratio can be measured by a circuit for detecting the standing wave ratio of the antenna shown in fig. 4 below in the terminal, wherein the standing wave ratio detection module 210 can transmit a high frequency signal, the bidirectional coupler 211 is used to transmit the high frequency signal to the antenna 212, assuming that the transmitted high frequency signal is d1 and the power is P1, d1 will be reflected if there is a path mismatch, the antenna is the main reflection source, if the power of the signal reflected by the antenna d1 is P2, the reflection coefficient f can be calculated as P2/P1, and the standing wave ratio of the antenna can be obtained by the reflection coefficient f and the following formula 1 (the standing wave ratio is identified as SWR in the following formula 1).
SWR ═ (1+)/(1-) (equation 1)
For the useful frequency band (i.e. the frequency band occupied by the terminal when establishing a call connection), generally, the smaller the standing-wave ratio of the antenna is, the higher the radiation efficiency of the antenna is. Illustratively, fig. 5 is a schematic representation of the standing wave ratio of the antenna without an object in proximity to the first screen and the second screen, when the standing wave ratio is identified as SWR2, fig. 6 is a schematic representation of the standing wave ratio of the antenna with an object in proximity to the first screen or the second screen, when the standing wave ratio is identified as SWR1, with frequency on the abscissa and standing wave ratio on the ordinate in fig. 5 and 6. For the standing-wave ratios in the two cases of fig. 5 and fig. 6, the difference between the standing-wave ratios of some frequency points is larger, for example, n1 and m1, n2 and m2 under the same frequency, and normally, when a call is answered, the antennas of the terminal are all close to the human head, and at this time, the standing-wave ratio of the antennas is increased accordingly, and the second threshold value can be determined by the difference between the standing-wave ratios in the two cases, for example, the difference between SWR1 and SWR2 under multiple frequency points, and the minimum difference value is used as the second threshold value. And thus determining that an object is close to the first screen and/or the second screen when the difference between the first standing wave ratio and the second standing wave ratio is greater than or equal to a second threshold, and determining that no object is close to the first screen or the second screen when the difference between the first standing wave ratio and the second standing wave ratio is less than the second threshold.
In the embodiment of the invention, when the difference value between the first intensity and the preset intensity is smaller than or equal to the first threshold value, it is indicated that no object is close to the first screen, and when the difference value between the current first standing-wave ratio and the current second standing-wave ratio of the terminal antenna is larger than or equal to the second threshold value, it is indicated that an object is close to the first screen or the second screen. Thus, it can be determined that the first screen has no object approaching and the second screen has an object approaching.
Optionally, in the embodiment of the present invention, if the terminal establishes the call connection and executes the above S11 and S12, then the second screen may be switched to the screen saver state in order to save power consumption of the screen.
The embodiment of the invention provides a proximity detection method, wherein a terminal comprises a first screen, a second screen, a standing-wave ratio detection module and an infrared detection module which is arranged aiming at the first screen, and the method comprises the following steps: acquiring first intensity of an infrared signal detected by an infrared detection module; if the difference value between the first intensity and the preset intensity is smaller than or equal to a first threshold value, and the difference value between the current first standing-wave ratio and the second standing-wave ratio of the terminal antenna, detected by the standing-wave ratio detection module, is within a second preset range, determining that an object is close to the second screen; the preset intensity is the intensity of the infrared signal detected by the infrared detection module under the condition that no object is close to the first screen; the second standing wave ratio is a standing wave ratio of the antenna without an object being close to the first screen and the second screen. Through the scheme, under the condition that the second screen is not provided with the infrared detection module, the difference value between the first strength and the preset strength can be smaller than or equal to the first threshold value, and the difference value between the current first standing-wave ratio and the second standing-wave ratio of the terminal antenna is larger than or equal to the second threshold value, it can be determined that an object is close to the second screen, the second screen can be switched to the screen-saving state at the moment, so that the infrared detection modules are not required to be arranged on the two screens in the double-sided screen terminal, and the approach detection can be realized, so that the cost and the design complexity of the double-sided screen terminal can be reduced.
Alternatively, in conjunction with fig. 2, as shown in fig. 7, S12 may be replaced with S13 described below.
And S13, if the difference value between the first intensity and the preset intensity is larger than a first threshold value, the terminal determines that an object approaches the first screen.
In the embodiment of the invention, under the condition that the difference value between the first intensity and the preset intensity is not within the first preset range, it can be determined that an object approaches the first screen.
Optionally, in the embodiment of the present invention, if the terminal establishes the call connection, the foregoing S11 and S13 are executed, at this time, in order to save power consumption of the screen, the first screen may be switched to the screen saver state. Therefore, the infrared detection module can be adopted in the double-sided screen terminal to realize the approach detection of the first screen.
Alternatively, in conjunction with fig. 2, as shown in fig. 8, S13 may be replaced with S14 described below.
And S14, if the difference value between the first intensity and the preset intensity is larger than the first threshold value and the difference value between the first standing-wave ratio and the second standing-wave ratio is not within the second preset range, the terminal determines that an object is close to the first screen.
Compared with the approach detection method shown in fig. 7, the approach detection method shown in fig. 8 can perform approach detection by using the standing-wave ratio of the antenna while performing approach detection by using the infrared detection module, thereby improving accuracy.
As shown in fig. 9, an embodiment of the present invention provides a terminal 130, where the terminal 130 includes a first screen and a second screen, and an infrared detection module is disposed for the first screen, and the terminal 130 includes: an acquisition module 131 and a switching module 132;
