Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the 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.

The embodiment of the invention provides a power detection method, a mobile terminal and a power detection circuit.

For ease of understanding, some concepts involved in embodiments of the present invention will be described first below.

TRP (Total Radiated Power): the transmission power of the whole radiation spherical surface is obtained by performing surface integration and averaging, is used for reflecting the transmission power condition of the whole electronic equipment, and is related to the transmission power of the electronic equipment under the conduction condition and the antenna radiation performance.

Conduction testing: power detection by the power detection circuit without connecting the antenna.

Coupling test: the power detection circuit performs power detection with the antenna connected.

An RF seat: also known as a radio frequency connector or a radio frequency test socket, before conducting a conduction test, the RF line of the integrated tester needs to be connected with the RF socket on the power detection circuit to be disconnected from the antenna, and then the conduction test can be conducted.

Next, a power detection method provided in an embodiment of the present invention is described.

Fig. 2 is a flow chart of a power detection method according to an embodiment of the present invention, which may include the following steps, as shown in fig. 2:

step 201: judging a test type corresponding to the current power detection operation, wherein the test type comprises at least one of a conduction test and a coupling test;

step 203: and calling a target parameter and carrying out power detection based on the test type.

It is understood that, in the embodiment of the present invention, the target parameter may be a preset conduction parameter or a preset coupling parameter. The preset conduction parameter records a mapping relation between the emission power and the conduction power detection value, and the preset coupling parameter records a mapping relation between the total radiation power TRP and the complete machine power detection value.

In the embodiment of the present invention, when step 201 is executed, it may be determined that the test type corresponding to the power detection operation is a conduction test or a coupling test by detecting the state of the RF socket on the power detection circuit. Specifically, if disconnection between an IN pin and an OUT pin of a radio frequency RF socket IN the power detection circuit is detected, it is determined that the test type corresponding to the current power detection operation is a conduction test; and if the connection between the IN pin and the OUT pin of the RF seat IN the power detection circuit is detected, determining that the test type corresponding to the current power detection operation is a coupling test.

In a more specific embodiment, it may be determined that the test type corresponding to the power detection operation is a conduction test or a coupling test by detecting a voltage of an RF _ DECT pin connected to an RF socket in the mobile terminal. Specifically, when the RF socket is not connected to the RF line of the integrated tester, the IN pin and the OUT pin of the RF socket are connected, the voltage of the RF _ DECT pin is at a low level, and the test type corresponding to the power detection operation is a coupling test; when the RF seat is connected with an RF line of the integrated tester, the IN pin and the OUT pin of the RF seat are disconnected, the voltage of the RF _ DECT pin is at a high level, and the test type corresponding to the power detection operation is a conduction test.

In the embodiment of the invention, the conduction parameters can be set by a radio frequency engineer according to experience, and can also be obtained by conducting and calibrating a large number of radio frequency circuit samples.

In the embodiment of the invention, the coupling parameters can be set by a radio frequency engineer according to experience, and can also be obtained by performing TRP calibration on a large number of radio frequency circuit samples.

In the embodiment of the invention, the conduction parameter and the coupling parameter can be integrated in the mobile terminal, compared with the prior art that the conduction parameter is only integrated in the mobile terminal, in the embodiment of the invention, the coupling parameter can also be integrated in the mobile terminal, so that the coupling parameter can be called when the coupling test is carried out on the mobile terminal, and the power detection result accuracy can be improved because the condition that the power of two antennas is mutually coupled is considered when the coupling parameter is designed.

In view of the fact that the coupling parameters obtained through the TRP calibration generally conform to the actual situation and are more accurate, in the embodiment of the present invention, the coupling parameters obtained through the TRP calibration may be preferentially selected and acquired, and stored in the mobile terminal.

In one example, the conduction parameter is shown in table 1, the coupling parameter is shown in table 2, and the recording manner shown in table 3 may be adopted when the conduction parameter and the coupling parameter are integrated in the mobile terminal.

In the embodiment of the present invention, when the test type corresponding to the current power detection operation is the conduction test, and the step 203 is executed to call the target parameter and perform the power detection based on the test type, whether the conduction power detection of the power detection circuit is qualified or not can be determined by calling the conduction parameter, and the conduction power detection value and the transmission power corresponding to the current power detection operation are obtained.

On the basis, if the mapping relation between the acquired conduction power detection value and the transmission power is recorded in the preset conduction parameter, the conduction power detection is determined to be qualified; and if the mapping relation between the acquired conduction power detection value and the transmission power is not recorded in the preset conduction parameters, determining that the conduction power detection is unqualified.

In an example, taking the power detection circuit shown in fig. 2 as an example, when an RF line of the integrated tester is connected to the RF socket 1 on the power detection circuit, only the directional coupler 1 couples power to the WiFi signal processor, and the WiFi signal processor performs analog-to-digital conversion on the power coupled to the directional coupler 1 to obtain a conduction power detection value.

For example, if the WiFi signal processor transmits a signal with a transmission power of 17dBm, the conduction power detection value processed by the WiFi signal processor is 15252, and comparison with the conduction parameter shown in table 1 shows that the corresponding relationship between the transmission power "17 dBm" and the conduction power detection value "15252" is recorded in the conduction parameter, it indicates that the conduction test of the power detection circuit is qualified.

On the basis of judging the test type corresponding to the current power detection operation in the step 201, when the test type corresponding to the current power detection operation is the coupling test, the step 203 is executed to call the target parameter based on the test type and perform the power detection, and a preset coupling parameter can be called, wherein the preset coupling parameter records the mapping relation between the total radiation power TRP and the complete machine power detection value.

In the embodiment of the invention, the base station environment is simulated through the comprehensive tester, and the coupling test is carried out on the power detection circuit of the mobile terminal.

In the embodiment of the invention, when the power detection circuit is subjected to coupling test, whether the coupling power detection of the power detection circuit is qualified or not can be determined by calling the coupling parameter, and the complete machine power detection value and the TRP corresponding to the current power detection operation are obtained. On the basis, if the mapping relation between the acquired complete machine power detection value and the TRP is recorded in the preset coupling parameter, the coupling power detection is determined to be qualified; and if the mapping relation between the acquired complete machine power detection value and the TRP is not recorded in the preset coupling parameters, determining that the coupling power detection is unqualified.

In one example, taking the power detection circuit shown in fig. 2 as an example, the comprehensive tester simulates a base station environment and instructs the WiFi signal processor to transmit a signal at a certain transmission power, and the WiFi signal processor performs analog-to-digital conversion on the power coupled to the directional coupler 1 (the power detection has two parts overlapping: 1 and 2 paths) to obtain a complete machine power detection value.

For example, if the WiFi signal processor transmits a signal with a transmission power of 17dBm, the corresponding TRP is 12dBm, the total power detection value processed by the WiFi signal processor is 16252, and the comparison with the coupling parameter shown in table 2 shows that the corresponding relationship between TRP "12 dBm" and the total power detection value "16252" is recorded in the coupling parameter, it indicates that the coupling test of the power detection circuit is qualified.

As can be seen from the above embodiments, in this embodiment, two sets of parameters may be stored in the mobile terminal in advance on the basis of the existing power detection circuit: the method comprises the steps of conducting parameters for conducting tests and coupling parameters for coupling tests, calling the conducting parameters when the mobile terminal detects the conducting tests, and calling the coupling parameters (the condition that the power of two antennas is coupled with each other is considered when the coupling parameters are designed) when the mobile terminal detects the coupling tests, so that the accuracy of the conducting test power is ensured through the conducting parameters, and the accuracy of the coupling test power is ensured through the coupling parameters.

Optionally, as an embodiment, the mobile terminal 400 may further include:

and the storage module is used for acquiring and storing the coupling parameters obtained through the TRP calibration.

In addition to the above-described power detection method improved in software, the embodiment of the present invention improves the existing power detection circuit, and the improved power detection circuit is shown in fig. 5 and 6.

In one example, the path where the first directional coupler is located is a path where a 2.4G WiFi signal is located, and the path where the second directional coupler is located is a path where a 5G WiFi signal is located, and since the low-pass filter has low loss for the 2.4G WiFi signal and the GPS signal and has high suppression for the 5G WiFi signal, the 5G WiFi signal on the path where the 2.4G WiFi signal is located can be filtered; the high-pass filter has low loss for 5G WiFi signals and high suppression degree for 2.4G WiFi signals, so that the 2.4G WiFi signals on a path where the 5G WiFi signals are located can be filtered.

It can be seen from the above embodiments that, in this embodiment, the existing power detection circuit may be improved, and filters are added between the directional coupler and the antenna on two radio frequency paths of the power detection circuit, respectively, to ensure that signals of the current radio frequency path are filtered while signals of other radio frequency paths are filtered, thereby improving the accuracy of the power detection result.

In one example, the path where the third directional coupler is located is a path where a 2.4G WiFi signal is located, and the path where the fourth directional coupler is located is a path where a 5G WiFi signal is located, in this case, when the 2.4G WiFi works normally, the switch turns on the third directional coupler and turns off the fourth directional coupler, and since the switch turns off the fourth directional coupler, the size of the 2.4G WiFi signal entering the power detection circuit through the coupling of the fourth antenna is reduced, so that the accuracy of the 5G WiFi power detection result is improved.

Similarly, when the 5G WiFi normally works, the switch is connected with the fourth directional coupler and is disconnected with the third directional coupler, and the switch is disconnected with the third directional coupler, so that the size of the 5G WiFi signal entering the power detection circuit through the third antenna in a coupling mode is reduced, and the accuracy of 2.4G WiFi power detection is improved.
