Fig. 1 is a flowchart of a signal processing method according to an embodiment of the present invention. As shown in fig. 1, the method may include the steps of:
step S102, the input power of the target radio frequency device fed back by the feedback circuit is obtained.
In the technical solution provided in the step S102 of the present invention, the feedback circuit may be a coupler feedback circuit, and the feedback circuit may be disposed in a radio frequency front end module (device) of the target radio frequency device, and is configured to monitor the input power of the target radio frequency device in real time, and feedback the input power monitored in real time.
Step S104, under the condition that the input power is larger than the target power threshold, a control instruction is sent to the target radio frequency device, wherein the control instruction is used for controlling the target radio frequency device to reduce the input power, and the reduced input power is smaller than the target power threshold.
In the technical scheme provided in the step S104, a target power threshold may be preset for the target radio frequency device, and when the real-time monitored input power fed back by the feedback circuit is greater than the target power threshold, a control command may be sent to the target radio frequency device, and after the target radio frequency device receives the control command and responds to the control command, the input power may be reduced until the input power is less than the target power threshold.

That is, by adding the feedback circuit, the input power of the target radio frequency device is fed back in real time, and the magnitude of the input power is controlled by setting the target power threshold value, so that the aim of protecting the target radio frequency device is fulfilled, the radio frequency device is prevented from being irreversibly damaged due to overlarge input power of the radio frequency device, the technical problem that the radio frequency device is easy to damage is solved, and the technical effect of preventing the radio frequency device from being damaged is achieved.
The above-described method of this embodiment is further described below.
As an alternative embodiment, before sending a control instruction to the target radio frequency device in step S104, the method includes: and determining a target power threshold corresponding to the target radio frequency device from a plurality of power thresholds, wherein each power threshold corresponds to one radio frequency device.
In this embodiment, since a plurality of rf devices may be included in one circuit, the power threshold of each rf device may be recorded, and then a target power threshold corresponding to the target rf device may be determined from the plurality of power thresholds.

In this embodiment, an analog-to-digital conversion circuit may be disposed, and since the input power of the target rf device acquired by the feedback circuit cannot be directly transmitted to the main chip in the target rf device, the input power of the target rf device acquired by the feedback circuit needs to be converted into a corresponding analog signal, so that the input power can be input to the main chip in the target rf device, and the main chip in the target rf device cannot directly identify the analog signal, and therefore, the analog signal needs to be converted into a corresponding digital signal by the analog-to-digital conversion circuit, so that the main chip in the target rf device can identify the input power fed back by the feedback circuit and compare with the target power threshold.
Alternatively, the analog-to-digital conversion circuit may be disposed on a main chip in the target rf device, and data is transmitted between the analog-to-digital conversion circuit and the digital-to-digital conversion interface of the main chip.

In this embodiment, a detection circuit may be provided, the input power of the target rf device acquired by the feedback circuit needs to be sent to the detection circuit, and the power signal is converted into an analog signal in the detection circuit, so that the analog signal of the input power of the target rf device acquired by the feedback circuit may be received by the analog-to-digital conversion circuit, and the analog signal is further converted into a digital signal.
Alternatively, in this embodiment, the analog signal converted by the detection circuit may be output to the digital conversion interface of the main chip of the target rf device, and the analog-to-digital conversion circuit receives the analog signal sent by the detection circuit through the digital conversion interface.
As an alternative embodiment, the input power fed back by the feedback circuit is input to the detection circuit through a switch.
In this embodiment, a switch may be provided, and after the input power of the target rf device is obtained by the feedback circuit, the input power is input to the detection circuit through the switch so that the detection circuit converts a power signal of the input power into an analog signal.
Optionally, the embodiment may further input the target power threshold of the target rf device to the detection circuit in combination with the coupling coefficient of the feedback circuit, so that the target power threshold of the target rf device may be transmitted to the target rf device, so that the target rf device compares the input power with the target power threshold.
In the above embodiment, the target power threshold of each rf device may be recorded and set in software, and since the target power threshold of each rf device may be different, when the input power of the same target rf device is detected, the input power may be directly compared with the target power threshold.
As an optional embodiment, step S104, sending a control instruction to the target radio frequency device includes: and sending a control instruction to the target radio frequency device through a feedback circuit.
In this embodiment, the feedback circuit may monitor the input power of the target rf device in real time and feedback the input power monitored in real time, and then the feedback circuit may send a control instruction to the target rf device based on the input power monitored in real time, so that the target rf device may adjust the input power in time.
In the related art, since each rf device has an input power limitation, when the input power exceeds the limitation, irreversible physical damage may occur to the rf device, for example, when a user holds a mobile phone, the antenna state may be changed, i.e. the load may be changed, so that the transceiver emits more power, and when the power emitted by the transceiver reaches a certain level, the emitted power exceeds the input power limitation of the rf device, thereby damaging the rf device.
The input power of the target radio frequency device is fed back in real time by adding the feedback circuit, and the magnitude of the input power is controlled by setting the target power threshold value, so that the aim of protecting the target radio frequency device is fulfilled, irreversible damage to the radio frequency device due to overlarge input power of the radio frequency device is avoided, the technical problem that the radio frequency device is easy to damage is solved, and the technical effect of preventing the radio frequency device from damage is achieved.
