Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
The embodiment of the invention provides a mobile terminal, which specifically comprises: the device comprises a processor, a functional device, a radio frequency device and a voltage detection circuit; wherein the processor is connected with the radio frequency device; the processor is connected with the functional device through a mobile industry processor interface control line; the mobile industry processor interface control line may include a data signal transmission line, the processor is connected to the voltage detection circuit, and the voltage detection circuit may be configured to detect a voltage value of the data signal transmission line; the processor may be configured to control the radio frequency device to perform an interference reduction operation so that the voltage value of the data signal transmission line detected by the voltage detection circuit satisfies a target range, if the voltage value does not satisfy the target range.
In the embodiment of the invention, the processor is connected with the functional device through an MIPI control line; the MIPI control line may include a data signal transmission line; the processor is connected to the voltage detection circuit, and the voltage detection circuit may be configured to detect a voltage value of the data signal transmission line. In practical application, since the frequency of the data signal transmitted by the data signal transmission line is stable, the voltage value of the data signal transmission line can reflect the signal quality of the MIPI control line. In the embodiment of the invention, the voltage value of the data signal transmission line can be detected in real time through the voltage detection circuit, and under the condition that the voltage value does not meet the target range, the signal quality of the MIPI control line can be considered to be abnormal. That is to say, in the embodiment of the present invention, by detecting the signal quality of the MIPI control line in real time, under the condition that the signal quality of the MIPI control line is abnormal, the interference of the radio frequency signal to the signal of the MIPI control line can be reduced, so that the functional component can operate normally.
Referring to fig. 1, a schematic structural diagram of a mobile terminal according to an embodiment of the present invention is shown, which may specifically include: a processor 10, a functional device 11, a radio frequency device 12, a Mobile Industry Processor Interface (MIPI) control line 13 and a voltage detection circuit 14; wherein, the processor 10 is connected with the radio frequency device 12; the processor 10 and the functional device 11 can be connected through an MIPI control line 13; MIPI control line 13 may include data signal transmission line 131; the processor 10 is connected to a voltage detection circuit 14, and the voltage detection circuit 14 can be used for detecting the voltage value of the data signal transmission line 131; the processor 10 may be configured to control the rf device 12 to perform an interference reduction operation if the voltage value does not satisfy the target range, so that the voltage value of the data signal transmission line detected by the voltage detection circuit may satisfy the target range. In the embodiment of the present invention, by detecting the signal quality of the MIPI control line 13 in real time, under the condition that the signal quality of the MIPI control line 13 is abnormal, the interference of the radio frequency signal to the signal of the MIPI control line 13 can be reduced, so that the functional component 11 can work normally.
In practical applications, the functional device 11 may be a camera assembly or a display screen assembly, and the like, and the embodiment of the present invention is described by taking the camera assembly as an example, and other types of functional devices may be executed by reference.
In the embodiment of the present invention, the MIPI control line 13 may be used to implement data exchange between the processor 10 and the functional device 11, and the MIPI control line 13 may further include a clock signal transmission line 132. Specifically, a data signal generated by the processor 10 may be transmitted to the functional device 11 through the data signal transmission line 131, and a clock signal generated by the processor 10 may be transmitted to the functional device 11 through the clock signal transmission line 132, so that the functional device can operate normally.
In practical applications, since the frequency of the data signal transmitted by the data signal transmission line 131 is stable, the voltage value of the data signal transmission line 131 can reflect the signal quality of the MIPI control line 13. Specifically, for the functional device 11, only when the voltage value on the data signal transmission line 131 connected to the functional device meets the target range, it can be considered that the radio frequency signal in the mobile terminal has less interference on the signal transmitted by the MIPI control line, and the functional device 11 can operate normally.
For example, in the case where the functional device 11 is a camera assembly, the target range may be 200 ± 20 mV. That is, only when the voltage value on the data signal transmission line 131 satisfies 200 ± 20mV, it can be considered that the radio frequency signal in the mobile terminal has less interference to the signal transmitted by the MIPI control line, and the camera can normally operate
It is understood that, in a specific application, the target range may be determined according to the type and the operation requirement of the functional device 11, and the specific content of the target range may not be limited by the embodiment of the present invention.
In the embodiment of the present invention, the voltage value of the data signal transmission line 131 may be detected in real time by the voltage detection circuit 14, and when the voltage value meets the target range, the signal quality of the MIPI control line 13 may be considered, and the functional component 11 may operate normally; in the case where the voltage value does not satisfy the target range, it may be considered that the signal quality of the MIPI control line 13 is abnormal, and an abnormal condition may occur in the operating state of the functional section 11.
Referring to fig. 2, a schematic diagram of a voltage detection circuit according to the present invention is shown, and as shown in fig. 2, the voltage detection circuit may include: and a microstrip line 20, the microstrip line 20 being disposed in parallel with the data signal transmission line 131.
One end of the first resistor 21 is grounded, and the other end of the first resistor 21 is connected with one end of the microstrip line 20.
And one end of the second resistor 22 is connected to the other end of the microstrip line 20, and the other end of the second resistor 22 is connected to the processor 10.
And one end of the third resistor 23 is connected with the other end of the microstrip line 20, and the other end of the third resistor 23 is grounded.
In the embodiment of the present invention, the microstrip line 20 may be disposed in parallel with the data signal transmission line 131. In practical applications, since the microstrip line 20 is disposed in parallel with the data signal transmission line 131, a coupling voltage of the data signal transmission line 131 can be generated on the microstrip line 20, and the loss of the coupling voltage is small.
For example, in the case where the voltage value of the data signal transmission line 131 is 200mV, since the microstrip line 20 is parallel to the data signal transmission line 131, a coupling voltage of 200mV can be generated on the microstrip line 20.
In practical applications, since the target voltage value that can be recognized by the processor 10 needs to satisfy a preset range, the coupling voltage generated on the microstrip line 20 often does not satisfy the preset range, that is, the coupling voltage generated on the microstrip line 20 may not be directly recognized by the processor 10.
For example, the voltage values that the processor 10 is able to identify may be voltage values above 800 mV. When the coupling voltage generated on the microstrip line 20 is 200mV, the coupling voltage cannot be directly recognized by the processor 10.
In the embodiment of the present invention, the voltage detection circuit may further include a first resistor 21, one end of the first resistor 21 is grounded, and the other end of the first resistor 21 is connected to one end of the microstrip line 20; and a second resistor 22, one end of the second resistor 22 is connected to the other end of the microstrip line 20, and the other end of the second resistor 22 is connected to the processor 10.
In practical applications, since the first resistor 21 and the second resistor 22 are connected in series, the currents of the first point resistor 21 and the second resistor 22 are consistent, and therefore, by adjusting the resistances of the first resistor 21 and the second resistor 22, the ratio of the coupling voltage generated on the microstrip line 20 to the target voltage value output by the voltage detection circuit to the processor 10 can be adjusted, so that the target voltage value can be recognized by the processor 10.
For example, the voltage value recognizable by the processor 10 may be a voltage value of 800mV or more, and in the case where the coupling voltage generated on the microstrip line 20 is 200mV at the minimum, the ratio of the coupling voltage generated on the microstrip line 20 to the target voltage value output by the voltage detection circuit to the processor 10 may be adjusted to be 1:4 by adjusting the ratio of the first resistor 21 to the second voltage 22, so that the target voltage value is recognizable by the processor 10.
In the embodiment of the present invention, the voltage value on the data signal transmission line 131 can be determined according to the target voltage value received by the processor 10 and output by the voltage detection circuit 14.
For example, when the ratio of the coupling voltage generated on the microstrip line 20 to the target voltage value output by the voltage detection circuit to the processor 10 is 1:4, when the target voltage value output by the voltage detection circuit 14 received by the processor 10 is 800mV, it is determined that the voltage value on the data signal transmission line 131 is 200 mV.
In the embodiment of the present invention, the voltage detection circuit may further include a third resistor 23, one end of the third resistor 23 is connected to the other end of the microstrip line 20, and the other end of the third resistor 23 is grounded.
In practical applications, the third resistor 23 may be used for impedance matching when the microstrip line 20 is coupled with the data signal transmission line 131.
In the embodiment of the present invention, the voltage value of the data signal transmission line 131 may be detected in real time by the voltage detection circuit 14, and when the voltage value does not satisfy the target range, it may be considered that the signal quality of the MIPI control line 13 is abnormal, and the working state of the functional component 11 may be abnormal. In this case, the processor 10 may control the radio frequency device 12 to perform an interference reduction operation to reduce interference of the radio frequency signal generated by the radio frequency device 12 on the signal of the MIPI control line 13, so that the voltage value of the data signal transmission line detected by the voltage detection circuit satisfies the target range. That is to say, in the embodiment of the present invention, by detecting the signal quality of the MIPI control line 13 in real time, under the condition that the signal quality of the MIPI control line 13 is abnormal, the interference of the radio frequency signal to the signal of the MIPI control line 13 can be reduced, so that the functional component 11 can operate normally.
In an optional embodiment of the present invention, the interference reduction operation may include: reducing the transmit power of the rf device 12. Specifically, in the case that the transmission power of the radio frequency device 12 is reduced, the strength of the radio frequency signal transmitted by the radio frequency device 12 is reduced, so that the interference of the radio frequency signal to the signal of the MIPI control line 13 can be reduced, and the functional component 11 can operate normally.
For example, in the case that the radio frequency device 12 is a transmitting antenna of a mobile terminal, by reducing the transmitting power of the transmitting antenna, the strength of the radio frequency signal transmitted by the transmitting antenna can be reduced, and the interference of the antenna radio frequency signal to the signal of the MIPI control line 13 can be reduced, so that the functional component 11 can operate normally.
Specifically, the reducing the transmission power of the rf device 12 may include reducing the transmission power of the rf device 12 step by a preset step until the voltage value of the data signal transmission line 131 detected by the voltage detection circuit 14 satisfies the target range.
In a specific application, in the case that the voltage value of the data signal transmission line detected by the voltage detection circuit does not satisfy the target range, the transmission power of the rf device 12 may be reduced step by step according to a preset step, the voltage detection circuit 14 detects the voltage value of the data signal transmission line 131 again each time the transmission power is reduced, and when the voltage value does not satisfy the target range, the reduction of the transmission power is continued until the voltage value of the data signal transmission line 131 detected again by the voltage detection circuit 14 satisfies the target range. By the method for reducing the transmission power of the radio frequency device 12, the interference of the radio frequency signal to the signal of the MIPI control line 13 is reduced, so that the functional component 11 can work normally.
In practical applications, the mobile terminal may further include: at least one transmitting antenna, which is a radio frequency device 12, and at least one receiving antenna. Specifically, the at least one transmitting antenna and the at least one receiving antenna tend to be located at different positions, and the farther the transmitting antenna as the radio frequency device 12 is located from the functional device 11, the lower the interference of the radio frequency signal generated by the transmitting antenna on the signal of the MIPI control line 13 is.
In another optional embodiment of the present invention, the interference reduction operation may include: and selecting one from the at least one receiving antenna to switch to a new transmitting antenna, and selecting one from the at least one transmitting antenna to switch to a new receiving antenna. Specifically, the transmitting antenna closer to the functional device 11 may be switched to a new receiving antenna, and a receiving antenna farther from the functional device 11 may be switched to a new transmitting antenna, so as to increase the distance between the new transmitting antenna and the functional device 11, so that the interference of the radio frequency signal generated by the new transmitting antenna on the signal of the MIPI control line 13 is reduced, and further, the functional device 11 may operate normally.
In practical applications, the interference reduction operation may further include: and detecting the fault conditions of the receiving antenna and the transmitting antenna, selecting one faulty receiving antenna from the at least one receiving antenna to be switched to a new transmitting antenna, and selecting one faulty transmitting antenna from the at least one transmitting antenna to be switched to the new receiving antenna.
In a specific application, in a case that the voltage value does not satisfy the target range, one of the at least one receiving antenna is selected to be switched to a new transmitting antenna, and one of the at least one receiving antenna is selected to be switched to a new receiving antenna, so as to increase a distance between the new transmitting antenna and the functional device 11, so that interference of a radio frequency signal generated by the new transmitting antenna on a signal of the MIPI control line 13 is reduced, and further, the functional device 11 can normally operate. The interference reduction method can reduce the interference of the antenna radio-frequency signal to the signal of the MIPI control line 13 on the premise of not influencing the antenna radio-frequency signal of the mobile terminal, that is, the interference reduction method has a small influence on the transmission of the antenna radio-frequency signal, and can improve the user experience of the user on the antenna of the mobile terminal.
