Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.

In order to ensure the quality of wireless terminal products, a series of tests are usually performed on the wireless terminal. For example, the wireless terminal will be calibrated first, and after the wireless terminal meets the terminal calibration conditions after the terminal calibration, the wireless terminal will be further comprehensively tested to further improve the accuracy of some parameters of the wireless terminal. Wherein, performing terminal calibration on the wireless terminal and comprehensive testing on the wireless terminal may be performing calibration or mediation on the transmit power or received signal strength of the wireless terminal. It can be understood that to further improve the accuracy of some parameters of the wireless terminal is to further improve the accuracy of the transmission power or received signal strength of the wireless terminal.

However, the inventors found that during the calibration process of wireless terminals, due to differences in environmental interference, temperature, humidity, power supply or other environmental factors, there may be residual errors in the power of each wireless terminal during comprehensive testing, resulting in wireless terminals after testing. The accuracy of the transmit power of the terminal is low. Further, since the accuracy of the transmission power of a single wireless terminal after testing is low, the consistency of the transmission power of multiple wireless terminals after batch testing is low.

Therefore, the inventor proposes a transmission power testing method, device, system and electronic equipment for improving the accuracy of the transmission power of the tested wireless terminals and the consistency of the transmission power of the batch tested wireless terminals in this application.

The following first introduces the transmission power testing method and the network environment in which the device operates provided by the present application.

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

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

When the test terminal 130 runs the signaling test program, it can control the terminal under test 110 to enter the signaling test mode, and when the terminal under test 110 enters the signaling test mode, it can establish a signaling connection with the radio frequency detection device 120. Making the connection may be that the radio frequency detection device 120 imitates a communication base station to establish a communication connection with the terminal under test 110 . When the test terminal 130 runs the non-signaling test program, it can control the terminal under test 110 to enter the non-signaling test mode. When the terminal under test 110 enters the non-signaling test mode, the terminal under test 110 can set the The parameter establishes a communication connection with the radio frequency detection device 120 . Wherein, the set parameters include a set communication frequency band, a set communication frequency point, and the like. The set parameters can be transmitted to the terminal under test 130 via USB or other means. When the test terminal 130 is running a complete non-signaling test program, it can control the terminal under test 110 to enter a complete non-signaling test mode, and when the terminal under test 110 enters a complete non-signaling test mode, it does not establish communication with the radio frequency detection device 120 connect. However, in the complete non-signaling test mode, the radio frequency detection device 120 can still detect the radio frequency signal transmitted by the terminal under test 130, and analyze the transmission power from the radio frequency signal.

However, when the test terminal 130 is running the signaling test program, the non-signaling test program and the complete non-signaling test program, it can load the corresponding required file, which carries the data required in the test process. For example, the loaded target power file contains the target transmit power during the transmit power test, so that the test terminal 130 can adjust the current transmit power of the terminal under test according to the target transmit power, and the loaded received signal strength target file contains There is a target received signal strength during the received signal strength test, so that the testing terminal 130 adjusts the current received signal strength of the terminal under test 130 according to the target received signal strength.

Wherein, during the operation of the system 100, the terminal under test 110 can transmit a radio frequency signal, and the radio frequency detection device 120 can receive the radio frequency signal transmitted by the terminal under test 110, and can also analyze the relevant information of the terminal under test 110 from the radio frequency signal. Parameters, for example, the transmit power of the terminal under test. Furthermore, the radio frequency detection device 120 can also transmit a radio frequency signal, and the terminal under test 110 can also receive the radio frequency signal, and can obtain the received signal strength when receiving the wireless signal. The testing terminal 130 can communicate wirelessly or wiredly with the terminal under test 110 and the radio frequency detection device 120 . Wherein, the wireless method may be WIFI or Bluetooth, etc., and the wired communication method may be USB or other serial port communication methods.

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

Please refer to Figure 2, a transmission power test method provided by the present application is applied to the above transmission power test system, and the method includes:

Step S110: The test terminal obtains the transmission power of the terminal under test sent by the radio frequency detection device, and the transmission power is based on the radio frequency signal transmitted by the terminal under test in a completely non-signaling test mode by the radio frequency detection device Obtain.

Step S120: Determine whether the transmit power is within a preset floating range based on the target transmit power.

Step S130: If no, determine that the transmit power of the terminal under test does not satisfy the terminal calibration condition.

Step S140: If yes, determine whether the transmission power meets the compensation condition.

Step S150: When the transmission power meets the compensation condition, adjust the transmission power of the terminal under test based on the obtained compensation value, so that the adjusted transmission power of the terminal under test is closer to the preset target transmit power.

Step S160: When the transmit power does not meet the compensation condition, it is judged that the current transmit power of the terminal under test does not need to be adjusted.

According to a transmission power testing method provided by the present application, when the test terminal judges that the transmission power is within the preset floating range based on the target transmission power, and the transmission power meets the compensation conditions, the tested The transmit power of the terminal under test is adjusted so that the adjusted transmit power of the terminal under test is closer to the preset target transmit power, so that the transmit power of the terminal under test can be closer to the target transmit power, and the transmit power of the terminal under test is improved. The accuracy of the power, and then also make the batch of tested terminals use the above method to test the transmission power, the batch test of the tested terminals can be closer to the target transmission power, and improve the transmission power consistency of the batch test wireless terminals.

Furthermore, when the terminal under test adopts a power back-off method to make the transmission power meet the SAR (Specific Absorption Rate) index, the transmission power can be backed back to the specified power value more accurately.

Please refer to Figure 3, a transmission power test method provided by the present application is applied to the above transmission power test system, and the method includes:

Step S210: The test terminal obtains the transmission power of the terminal under test sent by the radio frequency detection device, and the transmission power is based on the radio frequency signal transmitted by the terminal under test in a completely non-signaling test mode by the radio frequency detection device Obtain.

When the terminal under test is in a completely non-signaling test mode, although no communication connection has been established between the terminal under test and the radio frequency detection device, the radio frequency detection device can still detect the radio spectrum, thereby obtaining the detected radio spectrum transmit power.

Step S220: Determine whether the transmission power meets the compensation condition.

Step S230: When the transmission power does not meet the compensation condition, it is judged that the current transmission power of the terminal under test does not need to be adjusted.

Step S240: When the transmission power meets the compensation condition, adjust the transmission power of the terminal under test based on the acquired compensation value, so that the adjusted transmission power of the terminal under test is closer to the preset target transmit power.

As a way, in the transmission power test method provided in the present application, it is possible to judge that the transmission power does not meet the compensation condition and it is not necessary to go through multiple rounds of power adjustment before continuing the adjustment. As a way, before step S240 is executed, step S231 may be executed first: judge whether the round value of the current test round exceeds the preset value; when the round value of the current test round does not exceed the preset value, When the value is set, step 240 is executed to adjust the transmit power of the terminal under test in the next test round, so that the adjusted transmit power of the terminal under test is closer to the preset target transmit power. After step 240 is executed, return to step S210 again.

Step S250: When the number of rounds of the current test round exceeds a preset value, determine whether the transmit power is within a preset floating range based on the target transmit power.

Step S260: If yes, determine that the current transmit power of the terminal under test does not need to be adjusted.

Step S270: If not, determine that the transmit power of the terminal under test does not satisfy the terminal calibration condition.

It should be noted that the preset value corresponding to the number of rounds can be set according to the actual test situation, for example, it can be set to 5 times, 7 times, 8 times, etc.

It should be noted that, during each test round, the test terminal will store the determined current compensation value, that is, the compensation value used to adjust the transmit power of the terminal under test in the current round, into the terminal under test. Then, as a manner, the step of acquiring the compensation value includes: judging whether the terminal under test stores historical compensation values. The historical compensation value is a compensation value determined in the previous round of testing and used to adjust the transmit power of the terminal under test during the previous round of testing.

Then, when the historical compensation value is not stored in the terminal under test, the difference between the transmission power and the target transmission power is used as the current compensation value. When there is a historical compensation value, the data obtained by superimposing the difference between the transmission power and the target transmission power and the historical compensation value is used as the current compensation value, and the current compensation value is written into the The historical compensation value is overwritten in the terminal under test. It can be understood that after the current compensation value is written into the terminal under test and overwrites the historical compensation value, the current compensation value is the historical compensation value of the next round of testing.

In the transmission power testing method provided by the present application, after the radio frequency detection device obtains the transmission power of the terminal under test based on the radio frequency signal transmitted by the terminal under test in a completely non-signaling test mode, the transmission power is sent to the test terminal . When the test terminal judges that the transmission power meets the compensation condition, it adjusts the transmission power of the terminal under test based on the acquired compensation value, so that the adjusted transmission power of the terminal under test is closer to the preset target transmission power, thereby This makes the transmit power of the terminals under test closer to the target transmit power, improves the accuracy of the transmit power of the terminals under test, and furthermore, when all the terminals under test in batches use the above method to test the transmit power, the terminals under test in the batch test are all The transmission power can be closer to the target, and the consistency of the transmission power of the wireless terminals tested in batches can be improved.

Please refer to Figure 4, a transmission power test method provided by the present application is applied to the above transmission power test system, and the method includes:

Step S310: The test terminal loads the target power file.

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

Step S320: The radio frequency detection device performs data initialization.

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

Step S340: the terminal under test transmits a radio frequency signal.

Step S350: The radio frequency detection device acquires the transmit power of the terminal under test 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: Send the transmit power to the test terminal.

Wherein, the radio frequency detection device may send the analyzed transmit power to the test terminal after receiving the transmit power reading request sent by the test terminal. It is also possible to actively transmit the analyzed transmit power to the test terminal.

Step S370: the test terminal judges whether the transmission power meets the compensation condition.

As a manner, the compensation condition is that a difference between the transmit power of the terminal under test and the target transmit power is smaller than a preset compensation threshold. For example, when the target transmit power is 5dBm, the preset compensation threshold is 0.2dBm. Then when the transmit power is greater than 5.2dBm or less than 4.8dBm, and the difference between the transmit power acquired by the test terminal and the target transmit power is greater than 0.2dBm, it is judged that the transmit power does not meet the compensation condition. It should be noted that, when comparing the difference with the compensation threshold, only the numerical value of the difference may be compared with the compensation threshold, that is, the sign of the difference is not considered. Then, as a calculation method, the compensation condition may be that the absolute value of the difference between the transmit power of the terminal under test and the target transmit power is smaller than the compensation threshold.

Step S380: When the transmission power meets the compensation condition, adjust the transmission power of the terminal under test based on the obtained compensation value, so that the adjusted transmission power of the terminal under test is closer to the preset target transmit power.

As a manner, in the process of adjusting the transmission power, the current compensation value is obtained first, and the transmission power and the current compensation value are superimposed as the adjusted transmission power of the terminal under test. As a way of superposition, the sum of the transmission power obtained by the test terminal and the current compensation value may be directly used as the adjusted transmission power of the terminal under test.

In addition, the current compensation value may also be multiplied by a certain coefficient and then summed with the transmission power acquired by the test terminal to be used as the adjusted transmission power of the terminal under test. For example, when the difference between the currently obtained transmission power and the target transmission power is greater than a preset value, which indicates that the current deviation between the actual transmission power of the terminal under test and the target transmission power is relatively large, then the adjusted When measuring the transmit power of the terminal, after multiplying the difference between the currently obtained transmit power and the target transmit power by a certain coefficient, a value larger than the difference is obtained as the current compensation value, thereby enabling faster Adjust the transmit power of the terminal under test to reach the target transmit power.

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

It is understandable that the RF chips used by different terminals under test may be different. Correspondingly, the data format recognized by different RF chips may also be different. For the compensation value and power stored in different terminals under test The conversion between the difference values of may also be different. As a way, after the test terminal determines the current compensation value, it writes the current compensation value into the terminal under test, and first converts the current compensation value into a format that can be recognized by the RF chip of the terminal under test. written into the memory of the terminal under test. It can be understood that when the transmission power is determined by the corresponding gain multiple of the amplifier in the radio frequency circuit, when the terminal under test writes the current compensation value, it also follows the same principle as above, which will not be repeated here.

It can be understood that when the test terminal reads the historical compensation value from the terminal under test, it can convert the historical compensation value stored in a specific format in the terminal under test into a format that the test terminal can recognize, for example, the is the difference between the transmit power of the terminal under test and the target transmit power, then the format converted by the test terminal from the historical compensation value read from the test is also data of the same operation level as the aforementioned difference. It can be understood that the same operation level refers to data with the same data unit.

In the transmission power testing method provided by the present application, after the radio frequency detection device obtains the transmission power of the terminal under test based on the radio frequency signal transmitted by the terminal under test in a completely non-signaling test mode, the transmission power is sent to the test terminal . When the test terminal judges that the transmission power meets the compensation condition, it adjusts the transmission power of the terminal under test based on the acquired compensation value, so that the adjusted transmission power of the terminal under test is closer to the preset target transmission power, thereby This makes the transmit power of the terminals under test closer to the target transmit power, improves the accuracy of the transmit power of the terminals under test, and furthermore, when all the terminals under test in batches use the above method to test the transmit power, the terminals under test in the batch test are all The transmission power can be closer to the target, and the consistency of the transmission power of the wireless terminals tested in batches can be improved.
