In S301, when the camera module is in the operating state, it is determined whether the rf module is in the operating state.

In the embodiment of the present application, first, under the condition that the camera module 40 is in the working state, it is determined whether the radio frequency module 30 is in the working state; then, under the condition that the radio frequency module 30 is in a non-working state, the first movable contact end of the first single-pole double-throw switch is conducted with the fixed contact end of the first single-pole double-throw switch, and a signal of the camera module is sent to the control module through the filtering unit; under the condition that the radio frequency module 30 is in a working state, controlling a propagation path of a camera signal according to the working state of the radio frequency module 30 and the quality of the camera signal; under the condition that the camera module 40 is in a non-working state and the radio frequency module 30 is in a working state, the second movable contact end of the first single-pole double-throw switch is conducted with the fixed contact end of the first single-pole double-throw switch, and the radio frequency signal of the radio frequency module is controlled to be grounded through the camera module. In the embodiment of the present application, by determining the working states of the camera module 40 and the radio frequency module 30, a propagation path of an interference signal radiated from the radio frequency module 30 to the camera module 40 is determined, and if the interference is generated to the camera module 40, the interference is filtered by the filtering module 20, so as to avoid the interference to the imaging quality of the camera module 40 or the control module 10. By arranging the filtering module 20 between the camera module 40 and the control module 10, an interference signal radiated to the camera module 40 by the radio frequency module 30 can be filtered out, so that the problem of interference of the radio frequency module 30 to the camera module 40 is solved.
In one possible embodiment of the present application, the filtering unit may include: a second single pole double throw switch, a third single pole double throw switch and a tunable filter.
Under the condition that the radio frequency module 30 is in the working state, the propagation path of the camera signal is controlled according to the working state of the radio frequency module 30 and the quality of the camera signal, and the method comprises the following steps.
Step one, under the condition that the radio frequency module 30 is in a working state, the working mode of the radio frequency module 30 is determined, wherein the working mode comprises a time division duplex mode and a frequency division duplex mode.
That is to say, when the radio frequency module is in a working state, the working mode of the radio frequency module is judged first, and since the radio frequency module is in different working modes, the sending and receiving of signals are different, and the imaging quality needs to be prevented from being interfered according to actual conditions.
Step two, under the condition that the radio frequency module 30 is determined to be in the time division duplex mode, determining the time slot in which the radio frequency module 30 is located, where the time slot includes a Transmit (TX) time slot and a Receive (RX) time slot.
In this embodiment, the radio frequency module is in a time division duplex mode, the time division duplex mode includes a sending time slot and a receiving time slot, the two time slots are separated, the step six is performed when the receiving time slot is entered, and the step three to the step five are performed when the sending time slot is entered.
And step three, under the condition that the radio frequency module 30 is in the sending time slot, judging whether the camera signal of the camera module 40 meets the display requirement.
And step four, if the display requirement is met, controlling the camera signal to be directly sent to the control module 10 through the first single-pole double-throw switch, the second single-pole double-throw switch and the third single-pole double-throw switch.
And step five, if the display requirements cannot be met, controlling the camera signals to be filtered by the first single-pole double-throw switch, the second single-pole double-throw switch, the third single-pole double-throw switch and the adjustable filter and then sending the signals to the control module 10.
Further, in step six, when the radio frequency module 30 is in the receiving time slot, the control camera signal is directly sent to the control module 10 through the first single-pole double-throw switch, the second single-pole double-throw switch and the third single-pole double-throw switch.
The third step and the sixth step are two adjacent time slots, and when the radio frequency module 30 is in the beginning of the tdd mode, the receiving time slot is entered first, then the sending time slot is entered, and then the receiving time slot is entered, that is, the third step and the sixth step are not in strict order, and may be determined according to specific time, that is, the time length after the radio frequency module is switched to the tdd mode is related.
In this embodiment, when the radio frequency module 30 is determined to be in the operating state, it is determined whether the radio frequency module 30 is in the time division duplex mode or the frequency division duplex mode. If the time division duplex mode is adopted, whether the time slot is a sending time slot or a receiving time slot is further judged, and because the time slot is received without influencing the camera module 40, under the condition of receiving the time slot, a camera signal of the camera module 40 can directly enter the control module 10 through each switch for processing without filtering, under the condition of sending the time slot, whether the camera module is in a high-power transmitting state is required to be judged, if the camera module is in the high-power transmitting state, the transmitted signal can influence the camera module 40 to influence the imaging quality of the camera module, at the moment, whether the imaging quality of the camera module 40 meets the display requirement is required to be judged, and if the camera module is not in the high-power transmitting state, the interference signal radiated to the camera module 40 by the radio frequency module 30 is required to be filtered.
Wherein, under the condition that there is the interference at camera module 40, can be through adjusting tunable filter, filter the interfering signal of different frequencies, what can be better filters, promote camera module 40's imaging quality.
Specifically, the tunable filter can be tuned by determining the frequency band and the bandwidth of the signal transmitted by the radio frequency module 30, so that the tunable filter is in the corresponding filtering frequency band, and the interference signal is filtered out, thereby improving the imaging quality of the camera module 40.
It should be noted that whether the display of the camera module 40 meets the display requirement can be determined by the imaging quality.
In one possible embodiment of the present application, the control method may further include the following steps.
Under the condition that the radio frequency module 30 is judged to be in the frequency division duplex mode, the power of the radio frequency module 30 in the sending state is judged; judging whether a camera signal of the camera module 40 meets a display requirement or not under the condition that the power is greater than the preset power; if the display requirement is met, controlling the camera signal to be directly sent to the control module 10 through the first single-pole double-throw switch, the second single-pole double-throw switch and the third single-pole double-throw switch; if the display requirement cannot be met, the camera signal is controlled to be filtered by the first single-pole double-throw switch, the second single-pole double-throw switch, the third single-pole double-throw switch and the adjustable filter and then sent to the control module 10.
In this embodiment, when the radio frequency module is in the frequency division duplex mode, in this embodiment, it needs to be determined whether the radio frequency module 30 is in the transmission stage when it is determined that the radio frequency module is in the frequency division duplex mode, and if the radio frequency module is not in the transmission stage, the processing procedure is the same as that in the time division duplex mode, which is not described in detail in this embodiment. If the camera signal is in the transmitting stage, whether the camera signal is in the high-power transmitting stage and whether the display of the camera module 40 meets the display requirement are judged, and if the camera signal is met, the camera signal is directly sent to the control module 10 to be processed without filtering. If the display requirement is not met, the camera signal is filtered and then sent to the control module 10, so that the influence of interference signals is avoided, and the imaging quality is improved.
An embodiment of the present application further provides a control device, including: the device comprises a judgment module, a first control module, a second control module and a third control module.
Specifically, the judgment module is used for judging whether the radio frequency module is in a working state or not under the condition that the camera module is in the working state; the first control module is used for conducting a first movable contact end of the first single-pole double-throw switch and a fixed contact end of the first single-pole double-throw switch under the condition that the radio frequency module is in a non-working state, and a signal of the camera module is sent to the control module through the filtering unit; the second control module is used for controlling the propagation path of the camera signal according to the working state of the radio frequency module and the quality of the camera signal under the condition that the radio frequency module is in the working state; and the third control module is used for conducting the second movable contact end of the first single-pole double-throw switch and the fixed contact end of the first single-pole double-throw switch under the condition that the camera module is in a non-working state and the radio frequency module is in a working state, and controlling the radio frequency signal of the radio frequency module to be grounded through the camera module.
In the embodiment of the present application, firstly, the determining module determines whether the radio frequency module 30 is in the working state under the condition that the camera module 40 is in the working state; then, when the radio frequency module 30 is in a non-working state, the first movable contact end of the first single-pole double-throw switch is conducted with the fixed contact end of the first single-pole double-throw switch, and a signal of the camera module is sent to the control module through the filtering unit; the second control module controls the propagation path of the camera signal according to the working state of the radio frequency module 30 and the quality of the camera signal under the condition that the radio frequency module 30 is in the working state; in the third control module, when the camera module 40 is in a non-operating state and the radio frequency module 30 is in an operating state, the second movable contact of the first single-pole double-throw switch is conducted with the fixed contact of the first single-pole double-throw switch, and the radio frequency signal of the radio frequency module is controlled to be grounded through the camera module.
