For example, the preset signal strength threshold may be set to-90 dbm.
The antenna selection circuit in the embodiment of the invention can be applied to mobile terminals such as mobile phones. For convenience of explanation, the following embodiments are described with reference to a mobile phone as an example.
The primary WiFi antenna 11 and the secondary WiFi antenna 12 in the embodiment of the present invention are not shared with other antennas (e.g., a primary set antenna, a diversity antenna, a GPS antenna, etc.), and are only used by the WiFi module. That is to say, the mobile phone in the embodiment of the present invention sets two WiFi antennas dedicated to receiving WiFi signals: a primary WiFi antenna 11 and a secondary WiFi antenna 12. The position relationship between the primary WiFi antenna 11 and the secondary WiFi antenna 12 may be: the antenna radiator of the main WiFi antenna 11 and the antenna radiator of the auxiliary WiFi antenna 12 are disposed on two opposite sides of the mobile phone frame. As shown in fig. 2a, fig. 2a is a schematic diagram of relative positions of a main WiFi antenna and an auxiliary WiFi antenna disclosed in the embodiment of the present invention. As can be seen from the left diagram in fig. 2a, the antenna radiator of the main WiFi antenna 11 may be disposed at the top end of the frame of the mobile phone, and the antenna radiator of the auxiliary WiFi antenna 12 may be disposed at the bottom end of the frame of the mobile phone. As can be seen from the right diagram in fig. 2a, the antenna radiator of the main WiFi antenna 11 may be disposed on the left side of the frame of the mobile phone, and the antenna radiator of the auxiliary WiFi antenna 12 may be disposed on the right side of the frame of the mobile phone.
Optionally, the position relationship between the main WiFi antenna 11 and the auxiliary WiFi antenna 12 may also be: the antenna radiator of the main WiFi antenna 11 and the antenna radiator of the auxiliary WiFi antenna 12 are disposed on two adjacent sides of the mobile phone frame. As shown in fig. 2b, fig. 2b is a schematic diagram of the relative positions of another primary WiFi antenna and a secondary WiFi antenna disclosed in the embodiment of the present invention. As can be seen from the left diagram in fig. 2b, the antenna radiator of the main WiFi antenna 11 may be disposed at the top end of the frame of the mobile phone, and the antenna radiator of the auxiliary WiFi antenna 12 may be disposed at the right side of the frame of the mobile phone. As can be seen from the right diagram in fig. 2b, the antenna radiator of the main WiFi antenna 11 may be disposed at the top end of the frame of the mobile phone, and the antenna radiator of the auxiliary WiFi antenna 12 may be disposed at the left side of the frame of the mobile phone.
In a scenario where the user needs to use the handset across the screen, for example, when watching a video full screen or playing a game full screen. The palm of the hand of the user easily shields the antenna radiator part of the main WiFi antenna or the auxiliary WiFi antenna, which results in the deterioration of the WiFi signal received by the main WiFi antenna or the auxiliary WiFi antenna. Based on the above scenario, embodiments of the present invention provide an antenna selection circuit and an antenna selection method, which can ensure the strength of a WiFi signal received by a mobile terminal.
In the embodiment of the present invention, the switch 21 may be a single-pole double-throw switch. As shown in fig. 3a, the control module 31 may send a switching signal to the switch 21 to control the selection terminal 211 of the switch 21 to be connected to the main antenna connection terminal 212 or the auxiliary antenna connection terminal 213. At the same time, the selection terminal 211 of the changeover switch 21 can select only one of the main antenna connection terminal 212 and the auxiliary antenna connection terminal 213 to be connected.
Optionally, the switching signal includes a first switching signal or a second switching signal, where the first switching signal is specifically used to switch the WiFi module 41 to be connected to the auxiliary WiFi antenna 12 when the WiFi module 41 is connected to the main WiFi antenna 11. Specifically, the switch 21 is a single-pole double-throw switch, for example, and refer to the schematic diagram of the antenna switching circuit shown in fig. 3b, in an initial state, the WiFi module 41 is connected to the main WiFi antenna 11, the selection end 211 of the switch 21 is connected to the main antenna connection end 212, when the control module 31 detects that the WiFi signal strength received by the WiFi module 41 is smaller than the preset strength threshold, the control module 31 sends a first switching signal to the switch 21, so that the selection end 211 of the switch 21 is connected to the auxiliary antenna connection end 213, so as to connect the WiFi module 41 to the auxiliary WiFi antenna 12, and further, the WiFi antenna connected to the WiFi module is switched from the main WiFi antenna 11 to the auxiliary WiFi antenna 12.
The second switching signal is specifically used for switching the WiFi module 41 to be connected with the main WiFi antenna 11 when the WiFi module 41 is connected with the auxiliary WiFi antenna 12.
Specifically, the switch 21 is a single-pole double-throw switch, for example, as shown in the schematic diagram of the antenna switching circuit shown in fig. 3c, in an initial state, the WiFi module 41 is connected to the auxiliary WiFi antenna 12, the selection end 211 of the switch 21 is connected to the auxiliary antenna connection end 213, when the control module 31 detects that the WiFi signal strength received by the WiFi module 41 is smaller than the preset strength threshold, the control module 31 sends a second switching signal to the switch 21, so that the selection end 211 of the switch 21 is connected to the main antenna connection end 212, thereby connecting the WiFi module 41 to the main WiFi antenna 11, and further realizing that the WiFi antenna connected to the WiFi module is switched from the auxiliary WiFi antenna 12 to the main WiFi antenna 11.
The above example takes the case where the changeover switch 21 is a single-pole double-throw switch. Optionally, the switch 21 may also include a first switch tube and a second switch tube, and correspondingly, the switch 21 may include two control terminals 214. The first end of the first switch tube is connected to the selection end 211 of the switch 21, the second end of the first switch tube is connected to the main antenna connection end 212 of the switch 21, the first end of the second switch tube is connected to the selection end 211 of the switch 21, the second end of the second switch tube is connected to the auxiliary antenna connection end 213 of the switch 21, and the control ends of the first switch tube are respectively connected to one control end. At the same time, the control module 31 controls only one of the two switching tubes to be in a conducting state. The switching tube may be any one of a Metal Oxide Semiconductor (MOS) field effect Transistor, an Insulated Gate Bipolar Transistor (IGBT), a triode, or other semiconductor switching tube.
Optionally, as shown in fig. 4, fig. 4 is a schematic structural diagram of a mobile terminal disclosed in the embodiment of the present invention. The antenna selection circuit 10 in fig. 4 is applied to a mobile terminal 100, the mobile terminal 100 includes a gravity sensor 101, the control module 31 may be connected to the gravity sensor 101, and the control module 31 may receive the gravity sensor 101 to detect a change of a center of gravity of the mobile terminal to determine whether the mobile terminal is in a landscape state.
The control module 31 is further configured to detect the WiFi signal strength received by the WiFi module 41 when the gravity sensor 101 detects that the mobile terminal 100 is in the landscape state.
In the embodiment of the present invention, when the gravity sensor 101 detects that the mobile terminal 100 is in the landscape state, at this time, it is easy for the user to hold the two ends of the mobile phone, so that the main WiFi antenna 11 or the auxiliary WiFi antenna 12 of the mobile phone is shielded by the palm of the user, and the WiFi signal strength received by the WiFi module 41 is affected. The control module 31 of the embodiment of the present invention does not need to detect the WiFi signal strength received by the WiFi module 41 in real time, and only needs to detect in a specific application scenario (for example, the mobile terminal is in a landscape state), so that the power consumption of the mobile terminal can be saved.
Optionally, as shown in fig. 5, fig. 5 is a schematic structural diagram of another mobile terminal disclosed in the embodiment of the present invention. The mobile terminal 100 further includes a pressure sensor 102 disposed at a frame of the mobile terminal 100, and the pressure sensor 102 may be connected to the control module 31.
The control module 31 is further configured to detect a WiFi signal strength received by the WiFi module when the pressure value detected by the pressure sensor 102 is greater than a preset pressure threshold.
In the embodiment of the present invention, when the pressure value of the frame of the mobile terminal 100 detected by the pressure sensor 102 is greater than the preset pressure threshold, at this time, it is easy for the user to hold the two ends of the frame of the mobile phone, so that the main WiFi antenna 11 or the auxiliary WiFi antenna 12 of the mobile phone is shielded by the palm of the user, and the WiFi signal strength received by the WiFi module 41 is affected. The control module 31 of the embodiment of the present invention does not need to detect the WiFi signal strength received by the WiFi module 41 in real time, and only needs to detect in a specific application scene (for example, a scene where both ends of a cell phone frame are held by a user), so that the power consumption of the mobile terminal can be saved. For example, the preset pressure threshold may be set at 1 newton.
Optionally, as shown in fig. 6, fig. 6 is a schematic structural diagram of another mobile terminal disclosed in the embodiment of the present invention. The mobile terminal 100 further comprises a display screen 103, and the display screen 103 may be connected with the control module 31.
The control module 31 is further configured to output a prompt message through the display screen 103 when detecting that the WiFi signal strength is less than the preset strength threshold, where the prompt message is used to prompt a user whether the antenna area of the mobile terminal 100 is blocked.
In the embodiment of the present invention, when the gravity sensor 101 detects that the mobile terminal 100 is in the landscape state, the control module 31 detects the WiFi signal strength, and when the control module 31 detects that the WiFi signal strength is smaller than the preset strength threshold, the control module outputs the prompt information through the display screen 103, where the prompt information is used to prompt the user whether the antenna area of the mobile terminal 100 is blocked. According to the embodiment of the invention, when the control module 31 detects that the WiFi signal strength is smaller than the preset strength threshold value, the display screen outputs the prompt information to prompt the user whether the antenna is shielded by the hand. For example, the prompt message may be "please confirm whether to hold the antenna area at the top of the mobile phone, and if so, please take the hand away to avoid affecting the WiFi signal". The prompt message in the embodiment of the invention can remind the user whether the user shields the antenna by hands or not in time when the weak WiFi signal is detected.
Optionally, the control module 31 is further configured to send a switching signal to the switch 21 when detecting that the WiFi signal strength reduction ratio is greater than the preset ratio value.
In the embodiment of the invention, the WiFi signal strength weakening proportion is as follows: difference between current WiFi signal strength and initial WiFi signal strength/current WiFi signal strength. The preset proportional threshold may be set to 30%. For example, if the initial WiFi signal strength is-50 dbm and the current WiFi signal strength is-100 dbm, the calculated WiFi signal strength reduction ratio is 50%. The detection time of the initial WiFi signal strength is a period of time before the current time. For example, the difference between the detection time of the initial WiFi signal strength and the detection time of the current WiFi signal strength is 5 minutes. By detecting the weakening proportion of the WiFi signal strength, under the condition that the WiFi signal strength is weak, whether the antenna area of the mobile terminal is shielded or not can be judged more accurately.
Optionally, the control module 31 is further configured to determine, according to a correspondence between the foreground application and the signal strength threshold, a signal strength threshold corresponding to the currently running foreground application of the mobile terminal, and use the signal strength threshold corresponding to the currently running foreground application of the mobile terminal as the preset strength threshold.
Optionally, the control module 31 further includes a memory, and the memory is used for storing a corresponding relationship between the foreground application and the signal strength threshold.
In the practice of the invention, the memory may be a non-volatile memory. Different foreground applications require different minimum WiFi signal strengths, for example, a game application requires a larger WiFi signal strength, and an instant messaging application requires a smaller WiFi signal strength. The correspondence of foreground applications to signal strength thresholds may be preset and stored in the memory of the control module 31. As long as the current WiFi signal strength is greater than the signal strength threshold corresponding to the currently running foreground application, WiFi antenna switching is not required. The problem of unstable WiFi signals caused by frequent switching of WiFi antennas is avoided.
Optionally, the control module 31 is further configured to stop sending the switching signal to the switch 21 when detecting that the number of times of sending the switching signal to the switch within the preset time reaches a preset number of times.
In the embodiment of the present invention, for example, the preset time period may be set to be 1 minute or 2 minutes, and the preset number of times may be set to be 3 times or 5 times. By implementing the embodiment of the invention, the frequent switching of the WiFi antenna can be avoided, so that the problem of unstable WiFi signals caused by the frequent switching of the WiFi antenna is avoided.
Referring to fig. 7, fig. 7 is a flowchart illustrating an antenna selection method according to an embodiment of the present invention, and fig. 7 may be based on an antenna selection method provided in the apparatuses shown in fig. 1 to fig. 6. As shown in fig. 7, the antenna selection method includes the following steps:
701, the mobile terminal detects the strength of the WiFi signal received by the WiFi module.
702, when detecting that the WiFi signal intensity is less than the preset intensity threshold, the mobile terminal sends a switching signal to the switch, and the switching signal is used for controlling the switch to switch the WiFi antenna communicated with the WiFi module.
By implementing the method shown in fig. 7, the mobile terminal can switch the WiFi antenna connected with the WiFi module by detecting the strength of the WiFi signal, thereby ensuring the strength of the WiFi signal received by the mobile terminal.
