Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. 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 application.

In order to ensure the quality of the wireless terminal product, a series of tests are usually performed on the wireless terminal. For example, the wireless terminal may be calibrated first, and when the wireless terminal meets the terminal calibration condition through terminal calibration, the wireless terminal may be further comprehensively tested, so as to further improve the accuracy of some parameters of the wireless terminal. The calibration of the wireless terminal and the comprehensive measurement of the wireless terminal may be calibration or mediation of transmission power or received signal strength of the wireless terminal. It will be appreciated that further improving the accuracy of some parameters of the wireless terminal also further improves the accuracy of the transmit power or received signal strength of the wireless terminal.

However, the inventors have found that in the calibration process of the wireless terminal, the difference of environmental interference, temperature, humidity, power supply or other environmental factors may cause residual errors in the power of each wireless terminal during the integration process, so that the accuracy of the transmission power of the tested wireless terminal is low. Furthermore, the accuracy of the transmission power of a single wireless terminal after the test is low, so that the consistency of the transmission power of a plurality of wireless terminals after the batch test is low.

Therefore, the inventor proposes a transmission power test method, device, system and electronic device in the application, which can improve the accuracy of the transmission power of the tested wireless terminals and the consistency of the transmission power of the wireless terminals tested in batch.

The following first introduces a network environment in which the transmission power testing method and apparatus provided by the present application operate.

As shown in fig. 1, the present application provides a transmission power test system 100, where the system 100 includes a terminal under test 110, a radio frequency detection device 120, and a test terminal 130.

The test terminal 130 may be a computer or other intelligent devices. The test terminal 130 may run different test programs and load various types of files during the running of the test programs. For example, the test terminal 130 may run a signaling test program, a non-signaling test program, a completely non-signaling test program, and so on.

When the test terminal 130 runs the signaling test program, the tested terminal 110 may be controlled to enter the signaling test mode, and when the tested terminal 110 enters the signaling test mode, a signaling connection may be established between the tested terminal 110 and the radio frequency detection device 120, where the signaling connection may be that the radio frequency detection device 120 imitates a communication base station to establish a communication connection with the tested terminal 110. When the test terminal 130 runs the non-signaling test program, the tested terminal 110 may be controlled to enter the non-signaling test mode, and when the tested terminal 110 enters the non-signaling test mode, the tested terminal 110 may establish a communication connection with the radio frequency detection device 120 based on the parameters set by the test terminal 130. The set parameters comprise set communication frequency bands, set communication frequency points and the like. The set parameters may be transmitted to the terminal under test 130 via USB or other means. When the test terminal 130 runs the complete non-signaling test program, the tested terminal 110 may be controlled to enter the complete non-signaling test mode, and when the tested terminal 110 enters the complete non-signaling test mode, the communication connection with the radio frequency detection device 120 is not established. In the completely non-signaling test mode, the rf detection device 120 may still detect the rf signal transmitted by the terminal under test 130 and analyze the transmission power from the rf signal.

When the test terminal 130 runs the signaling test program, the non-signaling test program, and the complete non-signaling test program, a corresponding required file may be loaded, where the file carries data required in the test process. For example, the loaded target power file carries the target transmission power in the transmission power test process, so that the test terminal 130 adjusts the current transmission power of the terminal to be tested according to the target transmission power, and the loaded received signal strength target file carries the target received signal strength in the received signal strength test process, so that the test terminal 130 adjusts the current received signal strength of the terminal to be tested 130 according to the target received signal strength.

During the operation of the system 100, the terminal under test 110 may transmit a radio frequency signal, and the radio frequency detection device 120 may receive the radio frequency signal transmitted by the terminal under test 110, and may further analyze a relevant parameter of the terminal under test 110, for example, a transmission power of the terminal under test, from the radio frequency signal. Furthermore, the rf detection device 120 can also transmit an rf signal, and the terminal under test 110 can also receive the rf signal, and can obtain the received signal strength when receiving the wireless signal. The test terminal 130 may be in wireless or wired communication with the terminal under test 110 and the radio frequency detection device 120. The wireless mode can be WIFI or Bluetooth and the wired communication mode can be USB or other serial port communication modes.

Embodiments of the present application will be described in detail below with reference to the accompanying drawings.

Referring to fig. 2, a transmission power testing method provided in the present application is applied to the transmission power testing system, and the method includes:

step S110: the test terminal acquires the transmitting power of the tested terminal sent by the radio frequency detection equipment, and the transmitting power is acquired by the radio frequency detection equipment based on the radio frequency signal transmitted by the tested terminal in a complete non-signaling test mode.

Step S120: and judging whether the transmitting power is in a preset floating range taking the target transmitting power as a reference.

Step S130: and if not, judging that the transmitting power of the tested terminal does not meet the terminal calibration condition.

Step S140: and if so, judging whether the transmitting power meets a compensation condition.

Step S150: and when the transmitting power meets the compensation condition, adjusting the transmitting power of the tested terminal based on the obtained compensation value so as to enable the transmitting power of the tested terminal after adjustment to be closer to the preset target transmitting power.

Step S160: and when the transmitting power does not accord with the compensation condition, judging that the current transmitting power of the tested terminal does not need to be adjusted.

The application provides a pair of transmitting power test method, test terminal judge transmitting power be located with target transmitting power is the predetermined floating range of benchmark, and when transmitting power accorded with the compensation condition, based on the compensation value that obtains adjust by the transmitting power of survey terminal, make by the transmitting power after survey terminal adjustment more be close predetermined target transmitting power to make the transmitting power of survey terminal can be close target transmitting power more, promoted the accuracy of the transmitting power of survey terminal, and then also when making the terminal of being surveyed of batch all use above-mentioned mode test transmitting power, the terminal of being surveyed of batch test all can be closer to target transmitting power, promotes the transmitting power uniformity of the wireless terminal of batch test.

Moreover, when the measured terminal adopts a power back-off mode to enable the transmitting power to meet the SAR (specific Absorption rate) index, the transmitting power can be more accurately backed off to the specified power value.

Referring to fig. 3, a transmission power testing method provided by the present application is applied to the transmission power testing system, and the method includes:

step S210: the test terminal acquires the transmitting power of the tested terminal sent by the radio frequency detection equipment, and the transmitting power is acquired by the radio frequency detection equipment based on the radio frequency signal transmitted by the tested terminal in a complete non-signaling test mode.

When the tested terminal is in the completely non-signaling test mode, although no communication connection is established between the tested terminal and the radio frequency detection device, the radio frequency detection device can still detect the frequency spectrum of the radio, so as to acquire the detected transmission power of the radio.

Step S220: and judging whether the transmitting power meets a compensation condition.

Step S230: and when the transmitting power does not accord with the compensation condition, judging that the current transmitting power of the tested terminal does not need to be adjusted.

Step S240: and when the transmitting power meets the compensation condition, adjusting the transmitting power of the tested terminal based on the obtained compensation value so as to enable the transmitting power of the tested terminal after adjustment to be closer to the preset target transmitting power.

As one way, it is possible for the transmit power test method provided in the present application to determine that the transmit power does not meet the compensation condition and does not need to go through many rounds of power adjustment before continuing the adjustment. As one way, before performing step S240, step S231 may be performed: judging whether the round value of the current test round exceeds a preset value or not; and when the number of the current testing round does not exceed the preset value, executing step 240, so as to adjust the transmission power of the terminal to be tested in the next testing round, so that the adjusted transmission power of the terminal to be tested is closer to the preset target transmission power. After step 240 is executed, the process returns to step S210 again.

Step S250: and when the round number value of the current test round exceeds a preset value, judging whether the transmitting power is in a preset floating range taking the target transmitting power as a reference.

Step S260: if so, judging that the current transmitting power of the tested terminal does not need to be adjusted.

Step S270: if not, judging that the transmitting power of the tested terminal does not meet the terminal calibration condition.

It should be noted that the preset value corresponding to the round value may be set according to the actual test condition, for example, may be set to 5 times, 7 times, 8 times, and the like.

It should be noted that, during each test round, the test terminal stores the determined current compensation value, that is, the compensation value used for adjusting the transmission power of the terminal under test in the current test round, in the terminal under test. As one way, the step of obtaining the compensation value includes: and judging whether the tested terminal stores a historical compensation value. The historical compensation value is a compensation value which is determined in the previous round of test process and is used for adjusting the transmitting power of the tested terminal in the previous round of test process.

And when the historical compensation value is not stored in the tested terminal, taking the difference value between the transmitting power and the target transmitting power as the current compensation value. And when a historical compensation value exists, taking the data obtained by superposing the difference value of the transmitting power and the target transmitting power and the historical compensation value as a current compensation value, and writing the current compensation value into the tested terminal to cover the historical compensation value. It can be understood that, after the current compensation value is written into the terminal under test and the historical compensation value is overwritten, the current compensation value is the historical compensation value of the next test.

According to the transmission power test method, after the radio frequency detection equipment obtains the transmission power of the tested terminal based on the radio frequency signal transmitted by the tested terminal in the complete non-signaling test mode, the transmission power is sent to the test terminal. When the test terminal judges that the transmitting power meets the compensation condition, the transmitting power of the tested terminal is adjusted based on the acquired compensation value, so that the adjusted transmitting power of the tested terminal is closer to the preset target transmitting power, the transmitting power of the tested terminal can be closer to the target transmitting power, the accuracy of the transmitting power of the tested terminal is improved, and further, when the batch tested terminals use the above mode to test the transmitting power, the batch tested terminals can be closer to the target transmitting power, and the transmitting power consistency of the batch tested wireless terminals is improved.

Referring to fig. 4, a transmission power testing method provided by the present application is applied to the transmission power testing system, and the method includes:

step S310: and loading a target power file by the test terminal.

The test terminal may first run the non-signaling test program and load the target power file in the running program. The target power file carries parameters such as target transmission power.

Step S320: and the radio frequency detection equipment carries out data initialization.

Step S330: and the test terminal controls the tested terminal to enter a non-signaling test mode.

Step S340: and the tested terminal transmits a radio frequency signal.

Step S350: and the radio frequency detection equipment acquires the transmitting power of the terminal to be detected based on the radio frequency signal.

It can be understood that the transmission power acquired by the radio frequency detection device is the current actual transmission power of the terminal under test.

Step S360: and sending the transmitting power to the test terminal.

The radio frequency detection device can send the analyzed transmission power to the test terminal after receiving a transmission power reading request sent by the test terminal. The analyzed transmitting power can be actively transmitted to the test terminal.

Step S370: and the test terminal judges whether the transmitting power meets a compensation condition.

As a mode, the compensation condition is that a difference between the transmission power of the terminal to be tested and the target transmission power is smaller than a preset compensation threshold. For example, the target transmit power is 5dBm, and the predetermined compensation threshold is 0.2 dBm. And when the transmitting power is greater than 5.2dBm or less than 4.8dBm, judging that the transmitting power does not meet the compensation condition if the difference value between the transmitting power acquired by the test terminal and the target transmitting power is greater than 0.2 dBm. It should be noted that, when the difference is compared with the compensation threshold, only the value of the difference may be compared with the compensation threshold, that is, the sign of the difference is not considered. As a calculation manner, the compensation condition may be that an absolute value of a difference between the transmission power of the measured terminal and the target transmission power is smaller than a compensation threshold.

Step S380: and when the transmitting power meets the compensation condition, adjusting the transmitting power of the tested terminal based on the obtained compensation value so as to enable the transmitting power of the tested terminal after adjustment to be closer to the preset target transmitting power.

As a mode, in the process of adjusting the transmission power, a current compensation value is obtained first, and the transmission power and the current compensation value are superimposed to be used as the transmission power adjusted by the terminal to be measured. As a superposition mode, the transmit power obtained by the test terminal and the current compensation value may be directly summed to be used as the adjusted transmit power of the terminal under test.

In addition, the current compensation value may be multiplied by a certain coefficient and then summed with the transmission power obtained by the test terminal, so as to be used as the transmission power adjusted by the test terminal. For example, when the difference between the currently acquired transmit power and the target transmit power is greater than a preset value, the deviation between the actual transmit power representing the current measured terminal and the target transmit power is still relatively large, and when the transmit power of the measured terminal is adjusted, the difference between the currently acquired transmit power and the target transmit power is multiplied by a certain coefficient to obtain a value greater than the difference, which is used as a current compensation value, so that the transmit power of the measured terminal can be adjusted to reach the target transmit power more quickly.

It should be noted that, in the terminal under test, the offset value is stored in a specific format that can be recognized by the component responsible for the transmission power control in the terminal under test. For example, when the rf chip is responsible for controlling the transmission frequency in the terminal under test, the compensation value is stored in a format recognizable by the rf chip. As one way, when the transmission power of the terminal under test is determined by data in the RGI (calibration generated parameter list) or a gain multiple corresponding to an amplifier in the radio frequency circuit, the compensation value may be converted into corresponding data in the RGI or the gain multiple of the amplifier for storage.

It is understood that the rf chips used by different terminals under test may be different, and accordingly, the data formats recognized by different rf chips may also be different, and the conversion manner between the compensation value and the power difference stored in different terminals under test may also be different. As a mode, after determining the current compensation value, the test terminal converts the current compensation value into a format that can be recognized by the radio frequency chip of the terminal to be tested, and writes the format into the memory of the terminal to be tested. It can be understood that when the transmission power is determined by the gain multiple corresponding to the amplifier in the radio frequency circuit, the measured terminal writes the current compensation value according to the same principle as the foregoing one, and details are not described here.

It is understood that, when the test terminal reads the historical offset value from the terminal under test, the historical offset value stored in a specific format in the terminal under test may be converted into a format that can be recognized by the test terminal, for example, if the test terminal obtains a difference between the transmission power of the terminal under test and the target transmission power, the format converted by the historical offset value read by the test terminal from the terminal under test is also data of the same operation level as the difference. It is understood that the same operation level is data having the same data unit.
