Compared with the prior art, the test device can detect the actual power value of the test signal transmitted or received by the terminal to be tested, so that whether the terminal to be tested passes the test can be determined according to the actual power value and the expected parameter, if the terminal to be tested does not pass the test, the test device determines the compensation flag bit of the terminal to be tested according to the actual power value and the expected parameter and transmits the compensation flag bit to the terminal to be tested, after the terminal to be tested receives the compensation flag bit, a compensation parameter is obtained according to the compensation flag bit, the power value of the transmitted or received test signal is adjusted according to the compensation parameter, the adjusted power value of the test signal is more matched with the expected parameter, and the test passing rate of the terminal to be tested is improved; in addition, the power accuracy of the test signal can be improved on the basis of not influencing the test passing rate, the power control with higher accuracy is realized, and the power control performance of the terminal to be tested is improved.
A second embodiment of the present invention relates to a power control method, and is substantially the same as the first embodiment, and mainly differs therefrom in that: the specific implementation mode for determining the compensation zone bit of the terminal to be tested according to the actual power value and the expected parameter is provided.
Fig. 3 shows a specific flow of the power control method according to the present embodiment.
Step 201, detecting an actual power value of a test signal transmitted or received by a terminal to be tested.
This step is substantially the same as step 101 in the first embodiment, and will not be described herein again.
Step 202, comprising the following sub-steps:
substep 2021, obtain the desired power range from the desired parameters.
Specifically, the desired parameter includes a desired power value PE and a power tolerance value T, and then the desired power range is [ PE-T, PE + T ], and the power precision is [ [ -T, T ].
Sub-step 2022, determine if the actual power value is within the desired power range. If yes, directly ending; if not, go to step 203.
Specifically, the test client judges whether the actual power value PX is in an expected power range [ PE-T, PE + T ], namely whether | PX-PE | is smaller than or equal to T, when | PX-PE | is smaller than or equal to T, the actual power value PX is in the expected power range [ PE-T, PE + T ], which indicates that the terminal to be tested meets the power precision requirement, and judges that the terminal to be tested passes the test and directly ends the test; when the absolute value of PX-PE is greater than T, the actual power value PX is out of the expected power range [ PE-T, PE + T ], which indicates that the terminal to be tested does not meet the power precision requirement, the terminal to be tested is judged to fail to pass the test, and the step 203 is entered.
Step 203, comprising the following substeps:
sub-step 2031, determining the relation between the actual power value and the desired power range. If the actual power value is greater than the upper limit of the desired power range, then go to substep 2032; if the actual power value is less than the lower limit of the desired power range, then sub-step 2033 is entered.
Substep 2032, determining the compensation flag bit of the terminal to be tested as a power down flag.
Substep 2033, determining the compensation flag bit of the terminal to be tested as the power-up flag.
Specifically, the test client determines the relationship between the actual power value PX and the desired power range [ PE-T, PE + T ], i.e., determines the magnitude relationship between the actual power value PX and the lower limit value PE-T and the upper limit value PE + T of the desired power range. If PX is greater than PE + T, the actual power value PX of the test signal output by the terminal to be tested is larger than the power upper limit value PE + T, the actual power value PX of the test signal of the terminal to be tested needs to be reduced, and the compensation flag bit of the terminal to be tested is determined to be a power reduction flag 1; if PX is less than PE-T, it indicates that the actual power value PX of the test signal of the terminal to be tested is less than the power lower limit PE-T, the actual power value PX of the test signal of the terminal to be tested needs to be increased, and it is determined that the compensation flag bit of the terminal to be tested is the power-up flag 2. In addition, when the actual power value PX is within the expected power range [ PE-T, PE + T ], the test client may also obtain a compensation flag bit 0, which indicates that no compensation is performed.
And 204, sending the compensation zone bit to the terminal to be tested so that the terminal to be tested can obtain the compensation parameter according to the compensation zone bit and adjust the power value of the transmitted or received test signal according to the compensation parameter.
Specifically, the test client sends the compensation flag bit to the terminal to be tested, the corresponding relation between the compensation flag bit and the compensation parameter is prestored in the terminal to be tested, the terminal to be tested obtains the compensation parameter according to the compensation flag bit, and if the received compensation flag bit is 0, the terminal to be tested does not perform compensation; if the obtained compensation flag bit is a power reduction flag 1, the obtained compensation parameter is Nd; if the obtained compensation flag bit is the boosted power flag 2, the obtained compensation parameter is Nu. The calibration parameter Nb is pre-stored in the terminal to be measured, and the calibration parameter Nb and the compensation parameter are combined in a weighted manner to obtain a new calibration parameter, for example, if the compensation parameter is Nd, the new calibration parameter is Nb + Nd, so that the terminal to be measured is adjusted according to the new calibration parameter when transmitting or receiving the radio frequency signal.
Taking the expected power range [ PE-T, PE + T ] as an example, the following is specific:
if the actual power value PX falls within the range of [ PE-2T, PE-T), it indicates that the actual power value PX is less than PE-T, the test client obtains the compensation flag bit as the power-up flag 2, the terminal to be tested obtains the compensation parameter Nu corresponding to the power-up flag 2, the actual power value PX falls within the range of the expected power [ PE-T, PE + T ] through the compensation of Nu, and the compensation parameter Nu is 2T.
If the actual power value PX falls within the range of [ PE + T, PE +2T), it indicates that the actual power value PX is greater than PE + T, the test client obtains the compensation flag bit as the power down flag 1, the terminal to be tested obtains the compensation parameter Nd corresponding to the power down flag 1, the actual power value PX falls within the range of the expected power [ PE-T, PE + T ] through the compensation of Nd, and the compensation parameter Nu is 2T.
It should be noted that the power control method according to this embodiment may also be used to improve power accuracy, and the following description takes an expected power range [ PE-T, PE + T ] as an example, and specifically includes the following steps:
if the actual power value PX falls within the range of [ PE-T, PE-T/2), the test client triggers power-up compensation, the obtained compensation flag bit is the power-up flag 2, the terminal to be tested obtains the compensation parameter Nu corresponding to the power-up flag 2, the actual power value PX falls within the power range [ PE-T/2, PE + T/2] through the compensation of Nu, and the compensation parameter Nu is equal to T.
If the actual power value PX falls within the range of [ PE + T/2, PE + T), the test client triggers power reduction compensation, the obtained compensation flag bit is the power reduction flag 1, the terminal to be tested obtains the compensation parameter Nd corresponding to the power reduction flag 1, the actual power value PX falls within the power range of [ PE-T/2, PE + T/2] through compensation of Nd, and the compensation parameter Nu is T.
From the above, the power control method of the present embodiment can improve the power accuracy from [ -T, T ] to [ -T/2, T/2 ]. Referring to fig. 4 and 5, fig. 4 is a schematic diagram of a power limit distribution range without the power control method of the present embodiment, and the visible power precision is [ -1.5, 1.5], fig. 5 is a schematic diagram of a power limit distribution range with the power control method of the present embodiment, and the visible power precision is [ -0.75, 0.75], that is, the power precision is increased from [ -1.5, 1.5] to [ -0.75, 0.75 ].
In this embodiment, the maximum compensation range of the compensation parameter is obtained as follows:
if the actual power value Px is smaller than the lower power limit PE-T, the obtained compensation parameter is Nu, Nu makes Px + Nu fall within the expected power range [ PE-T, PE + T ], that is, the actual power value Px is smaller than the lower power limit PE-T
PE-T is not less than Px + Nu is not less than PE + T (formula 1)
Thus, PE-T-Nu Px is equal to or less than PE + T-Nu (formula 2)
In particular, Px ═ PE-T, available Nu ≦ 2T (equation 3)
If the actual power value Px is larger than the lower power limit value PE + T, the obtained compensation parameter is Nd, and the Nd enables the Px + Nd to fall within the expected power range [ PE-T, PE + T ], namely
PE-T is less than or equal to Px-Nd is less than or equal to PE + T (formula 4)
Thus, PE-T + Nd. ltoreq. Px. ltoreq. PE + T + Nd (equation 5)
In particular, Px ═ PE + T, available Nd ≦ 2T (equation 6)
Based on the above (equation-3) and (equation-6), the maximum compensation range can be derived:
Nd＝Nu＝2T
compared with the first embodiment, the present embodiment provides a specific implementation manner for determining the compensation flag of the terminal to be tested according to the actual power value and the expected parameter.
A third embodiment of the present invention relates to a power control method, and is substantially the same as the first embodiment, and mainly differs therefrom in that: whether the terminal to be detected is abnormal or not can be judged.
Fig. 6 shows a specific flow of the power control method according to the present embodiment.
Step 301 and step 302 are substantially the same as step 101 and step 102, and step 305 is substantially the same as step 103, which are not described herein again, but the main difference is that step 303 and step 304 are added, which are specifically as follows:
and step 303, judging whether the number of times that the terminal to be tested fails to pass the test reaches a preset number of times. If yes, go to step 304; if not, go to step 305.
Specifically, when it is determined in step 302 that the terminal to be tested does not pass the test, the test client determines whether the number of times that the terminal to be tested does not pass the test reaches a preset number of times, and if the number of times that the terminal to be tested does not pass the test reaches a preset number of times K, it indicates that the terminal to be tested still cannot pass the test after performing power compensation K-1 times, and the terminal to be tested cannot pass the test through the power compensation, and the process proceeds to step 304; otherwise, step 305 is executed to determine a compensation flag of the terminal to be tested according to the actual power value and the expected parameter, and send the compensation flag to the terminal to be tested, so that the terminal to be tested can obtain the compensation parameter according to the compensation flag, and adjust the power value of the transmitted or received test signal according to the compensation parameter.
And step 304, sending out prompt information for representing the abnormity of the terminal to be tested.
Specifically, the test client sends prompt information representing the abnormality of the terminal to be tested, and the specific way can be that the abnormality of the terminal to be tested is marked on a test interface of the test client and displayed to prompt a tester that the terminal to be tested is abnormal.
Compared with the first embodiment, the method and the device have the advantages that the judgment on whether the number of times that the terminal to be tested fails to pass the test reaches the preset number is added, so that whether the terminal to be tested is abnormal or not can be judged in time.

Specifically, calibration parameters are pre-stored in the terminal to be tested, the radio frequency signal transmitted or received by the terminal to be tested needs to be adjusted according to the calibration parameters, taking the terminal to be tested to transmit the test signal as an example, the power value of the test signal transmitted by the terminal to be tested is P, the calibration parameter is Nb, and the actual power value PX of the test signal is P + Nb, that is, the actual power value of the test signal detected by the detection device is P + Nb.
The test client judges the relationship between the actual power value PX and the expected power range [ PE-T, PE + T ], that is, the relationship between the actual power value PX and the lower limit value PE-T and the upper limit value PE + T of the expected power range is judged. If PX is greater than PE + T, the actual power value PX of the test signal output by the terminal to be tested is larger than the power upper limit value PE + T, the actual power value PX of the test signal of the terminal to be tested needs to be reduced, and the compensation flag bit of the terminal to be tested is determined to be a power reduction flag 1; if PX is less than PE-T, it indicates that the actual power value PX of the test signal of the terminal to be tested is less than the power lower limit PE-T, the actual power value PX of the test signal of the terminal to be tested needs to be increased, and it is determined that the compensation flag bit of the terminal to be tested is the power-up flag 2. In addition, when the actual power value PX is within the expected power range [ PE-T, PE + T ], the test client may also obtain a compensation flag bit 0, which indicates that no compensation is performed. And then, the test client sends the compensation zone bit to the terminal to be tested.
Step 502, when receiving the compensation flag bit sent by the test device, obtaining the compensation parameter corresponding to the compensation flag bit according to the corresponding relationship between the preset compensation flag bit and the compensation parameter.
Specifically, the corresponding relation between the compensation flag bit and the compensation parameter is pre-stored in the terminal to be tested, the terminal to be tested obtains the compensation parameter according to the compensation flag bit, and if the received compensation flag bit is 0, the terminal to be tested does not perform compensation; if the obtained compensation flag bit is a power reduction flag 1, the obtained compensation parameter is Nd; if the obtained compensation flag bit is the boosted power flag 2, the obtained compensation parameter is Nu.
Step 503, adjusting the calibration parameters according to the compensation parameters, and transmitting or receiving the test signal according to the compensated calibration parameters.
Specifically, a calibration parameter Nb is prestored in the terminal to be tested, and the calibration parameter Nb and the compensation parameter are weighted and combined to be adjusted, so as to obtain an adjusted calibration parameter, for example, if the compensation parameter is Nd, the adjusted calibration parameter is Nb + Nd, so that the terminal to be tested is adjusted according to a new calibration parameter when transmitting or receiving the radio frequency signal, taking the case that the terminal to be tested transmits the test signal as an example, the power value of the test signal transmitted by the terminal to be tested is P, and the adjusted calibration parameter is Nb + Nd, so that the actual power value PX of the test signal is P + Nb + Nd.
Taking the expected power range [ PE-T, PE + T ] as an example, the following is specific:
if the actual power value PX falls within the range of [ PE-2T, PE-T), it indicates that the actual power value PX is less than PE-T, the test client obtains the compensation flag bit as the power-up flag 2, the terminal to be tested obtains the compensation parameter Nu corresponding to the power-up flag 2, the actual power value PX falls within the range of the expected power [ PE-T, PE + T ] through the compensation of Nu, and the compensation parameter Nu is 2T.
If the actual power value PX falls within the range of [ PE + T, PE +2T), it indicates that the actual power value PX is greater than PE + T, the test client obtains the compensation flag bit as the power down flag 1, the terminal to be tested obtains the compensation parameter Nd corresponding to the power down flag 1, the actual power value PX falls within the range of the expected power [ PE-T, PE + T ] through the compensation of Nd, and the compensation parameter Nu is 2T.
It should be noted that the power control method according to this embodiment may also be used to improve power accuracy, and the following description takes an expected power range [ PE-T, PE + T ] as an example, and specifically includes the following steps:
if the actual power value PX falls within the range of [ PE-T, PE-T/2), the test client triggers power-up compensation, the obtained compensation flag bit is the power-up flag 2, the terminal to be tested obtains the compensation parameter Nu corresponding to the power-up flag 2, the actual power value PX falls within the power range [ PE-T/2, PE + T/2] through the compensation of Nu, and the compensation parameter Nu is equal to T.
If the actual power value PX falls within the range of [ PE + T/2, PE + T), the test client triggers power reduction compensation, the obtained compensation flag bit is the power reduction flag 1, the terminal to be tested obtains the compensation parameter Nd corresponding to the power reduction flag 1, the actual power value PX falls within the power range of [ PE-T/2, PE + T/2] through compensation of Nd, and the compensation parameter Nu is T.
From the above, the power control method of the present embodiment can improve the power accuracy from [ -T, T ] to [ -T/2, T/2 ]. Referring to fig. 4 and 5, fig. 4 is a schematic diagram of a power limit distribution range without the power control method of the present embodiment, and the visible power precision is [ -1.5, 1.5], fig. 5 is a schematic diagram of a power limit distribution range with the power control method of the present embodiment, and the visible power precision is [ -0.75, 0.75], that is, the power precision is increased from [ -1.5, 1.5] to [ -0.75, 0.75 ].
In this embodiment, the maximum compensation range of the compensation parameter is obtained as follows:
if the actual power value Px is smaller than the lower power limit PE-T, the obtained compensation parameter is Nu, Nu makes Px + Nu fall within the expected power range [ PE-T, PE + T ], that is, the actual power value Px is smaller than the lower power limit PE-T
PE-T is not less than Px + Nu is not less than PE + T (formula 1)
Thus, PE-T-Nu Px is equal to or less than PE + T-Nu (formula 2)
In particular, Px ═ PE-T, available Nu ≦ 2T (equation 3)
If the actual power value Px is larger than the lower power limit value PE + T, the obtained compensation parameter is Nd, and the Nd enables the Px + Nd to fall within the expected power range [ PE-T, PE + T ], namely
PE-T is less than or equal to Px-Nd is less than or equal to PE + T (formula 4)
Thus, PE-T + Nd. ltoreq. Px. ltoreq. PE + T + Nd (equation 5)
In particular, Px ═ PE + T, available Nd ≦ 2T (equation 6)
Based on the above (equation-3) and (equation-6), the maximum compensation range can be derived:
Nd＝Nu＝2T
it should be noted that, in this embodiment, different status registers are respectively set for the transmitting channel and the receiving channel in the terminal to be tested, so that independent power control of the terminal to be tested for transmitting the test signal and receiving the test signal is achieved, and the specific control manner of the transmitting channel and the receiving channel is similar to that described above, and is not described herein again.
