Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a flowchart of a method for detecting an rf path according to an embodiment of the present invention.
Before specifically describing the implementation process of the method, it should be noted that a schematic structural diagram of a radio frequency path corresponding to the method for detecting a radio frequency path in the embodiment of the present invention is shown in fig. 2.
The radio frequency path includes: a transceiver, a power amplifier, a duplexer, an antenna switch module, a tuning device, a coupler, and a feedback path.
The central processing unit of the mobile terminal is respectively connected with the transceiver and the preset device.
Here, the transceiver transmits a low power signal, which is amplified by a power amplifier, and then transmitted by an antenna through a coupler.
The implementation of the method is described in detail below with respect to fig. 1.
Here, the preset device may be a camera, an infrared sensor, a speaker, a motor, a flash, or the like.
It should be noted that the radio frequency path includes: a transmit path and a receive path.
Here, the preset device generates the first signal having a preset frequency. Wherein the magnitude of the predetermined frequency is related to the frequency of the second signal.
Specifically, since the second signal is a signal transmitted by a transmission path in the radio frequency path, the frequency of the second signal is a main frequency of a transmission frequency band of the mobile terminal.
Here, the first signal is intermodulated with the second signal to produce an intermodulation product. For example, if the frequency of the first signal is F1 and the frequency of the second signal is F2, the intermodulation product F obtained by the first signal and the second signal after intermodulation is mf1 ± nf 2.
Wherein F is an intermodulation product, and m and n are positive integers including 1.
Here, the noise signal includes: the first signal, the second signal and an intermodulation product generated by the intermodulation of the first signal and the second signal.
Here, the default device is differentiated between the normal operation mode and the rf path detection mode, in which the default device has a signal output with a preset frequency, i.e. a first signal, for intermodulation with a second signal transmitted by the transmission path to generate an intermodulation product with a frequency falling within the reception band of the mobile terminal.
It should be noted that, through the preset operation of the user on the mobile terminal, the mobile terminal can enter the radio frequency channel detection mode.
And 102, determining the abnormal state of the radio frequency path according to the noise signal, wherein the radio frequency path comprises a tuning device.
Here, the tuning device is located at the front end of the antenna, as shown in fig. 2.
It should be noted that, in the embodiment of the present invention, the signal spectrum of f1+ f2 in the intermodulation product generated by the intermodulation of the first signal and the second signal falls within the spectrum range of the receiving frequency band.
Here, the abnormal state of the radio frequency path is determined by mobile terminal detection and demodulation of a noise signal, using the characteristic that the spectrum of the intermodulation signal with the frequency f1+ f2 generated by the above-mentioned intermodulation of the first signal and the second signal falls within the spectrum range of the reception band.
It should be noted that, in this embodiment, when the radio frequency path is abnormal, the abnormal data of the radio frequency path is reported to the server for performing large data analysis at a later stage, so as to obtain an occupation ratio of a bad single machine caused by the abnormal radio frequency link. The embodiment can realize the detection of the abnormal state of the radio frequency path comprising the tuning device, and expand the range of the detection of the abnormality of the radio frequency path, thereby improving the accuracy of analyzing the big data to obtain the occupation ratio of the bad single machine caused by the abnormality of the radio frequency link.
According to the method for detecting the radio frequency path, the noise signal generated after intermodulation of the first signal generated by the preset device connected with the processor and the second signal transmitted by the transmitting path in the radio frequency path is obtained, and the abnormal state of the radio frequency path including the tuning device is determined according to the noise signal. Therefore, the abnormal state of the radio frequency channel comprising the tuning device can be detected, the abnormal detection range of the radio frequency channel is expanded, and the accuracy of the occupation ratio of the bad single machine caused by the abnormal radio frequency link obtained through big data analysis can be improved.
Preferably, the second signal is a signal transmitted by said transmission path at a maximum transmission power.
It should be noted that, the central processing unit of the mobile terminal sends the control signal to control the transmission path to transmit the second signal with the maximum transmission power. The method aims to improve the signal intensity and improve the data analysis precision when the subsequent mobile terminal scans and analyzes the noise signal.
On the basis of the embodiment shown in fig. 1, as a preferred implementation manner, as shown in fig. 3, step 101 may include:
When it is monitored that the mobile terminal enters a radio frequency access detection mode, a central processing unit connected with a preset device sends a first control instruction for starting the preset device to the preset device, and the preset device generates a first signal with preset frequency after being started.
And when the mobile terminal is monitored to enter the radio frequency access detection mode, a second control instruction is sent to forcibly enable the radio frequency access to be opened. Here, the active devices on the rf path are mainly in an active state.
Here, the noise signal generated by the first signal and the second signal after being intermodulated in the propagation medium includes: the first signal, the second signal and an intermodulation product generated by the intermodulation of the first signal and the second signal.
For example, the frequency of the first signal is F1, and the frequency of the second signal is F2, so that the intermodulation product F after the first signal is intermodulated with the second signal is mf1 ± nf2, where F is the intermodulation product, and m and n are positive integers including 1.
Here, in order to determine the abnormal state of the rf path by using the noise signal, based on the embodiment shown in fig. 1, as a preferred implementation manner, as shown in fig. 4, step 102 may include:
Here, the antenna of the mobile terminal receives a noise signal, since the noise signal includes: the first signal, the second signal and the intermodulation product generated by the intermodulation of the first signal and the second signal, namely the signals with a plurality of different frequencies, demodulate the noise signal when passing through a receiving channel of a radio frequency channel, and filter the signals except the intermodulation product of which the frequency falls into the receiving frequency band of the mobile terminal in the intermodulation product generated by the first signal, the second signal and the intermodulation of the first signal and the second signal. That is, an intermodulation product whose signal frequency falls within the reception band of the mobile terminal is demodulated.
Of course, the above is the processing procedure in the case where the rf path is normal.
Here, the noise scan result may include: the frequency band range of the noise signal after the noise scanning and the signal intensity in the corresponding frequency band range.
It should be noted that the noise signal after noise scanning, i.e. the intermodulation product whose signal frequency falls within the receiving frequency band of the mobile terminal.
The causes of the radio frequency channel abnormity in the embodiment of the invention comprise: transmission path anomalies, reception path anomalies, and tuning device anomalies at the front end of the antenna.
If the transmission path is abnormal, the first signal with the preset frequency generated by the preset device cannot be subjected to intermodulation, and further, when the noise signal is subjected to noise scanning, the frequency spectrum of the receiving frequency band cannot be scanned, namely, the noise scanning result is compared with the range of the preset receiving frequency band, and the range of the frequency band of the noise signal does not fall into the range of the preset receiving frequency band.
If the receiving path is abnormal, even if the second signal transmitted by the transmitting path can generate intermodulation with the first signal with the preset frequency generated by the preset device to obtain the noise signal, the noise signal cannot be scanned, then the noise scanning result is compared with the preset receiving frequency band range, the frequency band of the noise signal falls into the preset receiving frequency band range, and the signal intensity of the noise signal is greatly different from the preset signal intensity.
Furthermore, if the tuning device is abnormal, the radiation capability of the second signal generated by the transmission path of the rf path is weakened, which results in the reduction of the signal strength of the intermodulation product, and the reception sensitivity of the reception path is reduced, so that the difference between the spectrogram of the noise signal after noise scanning and the preset spectrum is large. It can be understood that the difference between the signal strength of the noise signal after the noise scanning and the preset signal strength is very large.
Therefore, based on this, the step 1022 may specifically include: determining that a transmitting channel of the radio frequency channel is abnormal under the condition that the noise scanning result indicates that the frequency range of the noise signal does not fall into a preset receiving frequency range;
or, determining that the receiving path of the radio frequency path or the tuning device of the radio frequency path is abnormal under the condition that the frequency range falls into a preset receiving frequency range and the difference value between the signal intensity of the noise signal and the preset signal intensity is greater than a preset threshold value.
It should be noted that the preset signal strength corresponds to a preset receiving frequency band. I.e. different reception frequency points correspond to different signal strengths.
Here, the corresponding relationship between the preset signal strength and the preset receiving frequency band may be stored in a form of a graph, which is convenient for a central processing unit of the mobile terminal to search and compare with a noise scanning result.
Note that the noise scan result can be represented by in-phase and quadrature data.
According to the method for detecting the radio frequency path, the noise signal generated after intermodulation of the first signal generated by the preset device connected with the processor and the second signal transmitted by the transmitting path in the radio frequency path is obtained, and the abnormal state of the radio frequency path including the tuning device is determined according to the noise signal. Therefore, the abnormal state of the radio frequency channel comprising the tuning device can be detected, the abnormal detection range of the radio frequency channel is expanded, and the accuracy of the occupation ratio of the bad single machine caused by the abnormal radio frequency link obtained through big data analysis can be improved.
