Fig. 2 is a schematic flowchart illustrating another radio frequency power calibration method provided in an embodiment of the present application, where as shown in fig. 2, the method includes:
step 201: and configuring a plurality of channel groups corresponding to each wireless local area network mode according to the corresponding relation between the preset mode and the channel division.
In the present application, the wireless local area network (WiFi) mode may include: the 802.11a/b/G/n/ac/ax and other systems, each system has different rate levels in each channel, the rate levels which can be communicated by both parties can be determined between the devices according to the device capability, environmental interference and the like, the WiFi2.4G/5G channels are more, the radio frequency power test points are more, all channels can be divided, the corresponding relation between each mode and the channel division can be stored as a table, and the configuration of each wireless local area network mode and each channel group is completed based on the table.
For example, 13 channels are 2.4G, channels 1-4 are divided into a first channel group (Band 0), channels 5-9 are divided into a second channel group (Band 1), and channels 10-13 are divided into a third channel group (Band 2), and the transmitting units of each channel group are independent and do not affect each other, so that only a calibration test needs to be performed on each channel group, and more than three times of calibration terms can be reduced, thereby improving efficiency, wherein the calibration range of each channel group is ± X decibel milliwatts (dBm).
In the present application, the first power compensation value and the second power compensation value both belong to compensation values, and the determination of the compensation values may comprise the following sub-steps:
substep S1: and obtaining deviation power values b of all the rates, if all the deviation power values b meet | b | ≦ 1.5dBm, judging that the calibration is successful, jumping to the substep S6, and if all the deviation power values b meet | b | ≦ 2.2dBm, jumping to the substep S4.
And a substep S2: and calculating compensation values of all bands, namely the first power compensation value, and configuring the compensation values into the equipment to be effective.
Substep S3: a jump is made to substep S1.
And a substep S4: the compensation values for all rates, i.e. the second power compensation values, are calculated and configured into the device to be effective.
And a substep S5: a jump is made to substep S1.
Substep S6: the flow ends.
Step 202: and calibrating the power of the data to be calibrated corresponding to each channel group according to a first preset power adjustment parameter to obtain a first power compensation value, and calibrating the data to be calibrated based on the first power compensation value to obtain first power calibration data.
The data range corresponding to the first preset power adjustment parameter is as follows: -5 db mw to 5db mw;
in the present application, the calculation of the first power compensation value for each channel group may include the sub-steps of:
substep A1: acquiring radio frequency power deviation values of all rates of a first channel in the channel group; and if at least one of the absolute values of the radio frequency power deviation values is larger than a first preset radio frequency power deviation value, determining that the product to be tested corresponding to the data to be calibrated is a defective product.
The substep A2 can determine the maximum power deviation value and the minimum power deviation value of the first channel in the channel group; determining a radio frequency power maximum deviation threshold based on the maximum power deviation value and the minimum power deviation value; and if the maximum deviation threshold value of the radio frequency power is larger than a preset maximum deviation threshold value of the radio frequency power, determining that the product to be detected corresponding to the data to be calibrated is a defective product.
In the present application, the maximum deviation threshold of the preset rf power is 4.4dBm.
Specifically, after a certain channel group is compensated, assuming that the power compensation value of the channel group is b, the power of all rates in the channel group is superimposed by b, and then after each rate of each channel in the channel group is compensated by R, the power value of each rate in the channel group will have one of the following 4 changes:
when R >0 and b >0, then | R + b | > | R |, the deviation becomes larger;
when R is greater than 0 and b is less than 0, then | R + b | < | R |, the deviation becomes smaller;
when R <0 and b >0, then | R + b | < | R |, the deviation becomes smaller;
when R <0 and b <0, then | R + b | > | R |, the deviation becomes larger;
that is, after adjustment, the rate of the same channel group may become larger or smaller, and it is ensured that the deviation value of each rate is not greater than 1.5dBm, so that the difference between the maximum deviation power value Kmax and the minimum deviation power value Kmin cannot be too large, otherwise the target power cannot be achieved through calibration, i.e. good products must meet the requirement of good products
L Kmax-Kmin is less than or equal to m (m is a fixed constant);
the specific values of m will be derived next:
according to the formula (3), it can be known that each rate in the same channel group of good products must satisfy
|Kmax+b+R1|≤1.5dBm；
|Kmin+b+R2|≤1.5dBm，
Wherein the content of the first and second substances,
kmax is the power value of the rate with the largest deviation in the same channel group, and the corresponding rate compensation value is marked as R1.
Kmin is the power value of the rate with the minimum deviation in the same channel group, and the corresponding rate compensation value is marked as R2.
According to the absolute value inequality that | a | - | b | < | a-b |, the method can obtain
|Kmax-Kmin|-|R2–R1|≤|(Kmax-Kmin)–(R2–R1)|＝|(Kmax+R1)–(Kmin+R2)|＝|(Kmax+R1+b)–(Kmin+R2+b)|
I.e. | Kmax-Kmin | - | R2-R1| < | (Kmax + R1+ b) - (Kmin + R2+ b) | (4);
according to the absolute value inequality that | a | - | b | < | a | + | b |, the obtained
|(Kmax+R1+b)–(Kmin+R2+b)|≤|Kmax+b+R1|+|Kmin+b+R2|≤1.5+1.5＝3dBm
I.e., | (Kmax + R1+ b) - (Kmin + R2+ b) | is less than or equal to 3dBm (5);
combine (4) and (5) to obtain
|Kmax-Kmin|-|R2–R1|≤|(Kmax+R1+b)–(Kmin+R2+b)|≤3dBm
I.e. | R2-R1| +3dBm (6) is less than or equal to | Kmax-Kmin |;

Substep B3: if | K | >1.5+, 0.7=2.2dBm, then | K | =0.7, otherwise | K | = | K | -1.5, the polarity preservation value of K is unchanged.
Substep B4: the compensation value K is configured to the device to perform the radio frequency power compensation at this rate, and the substep B1 is skipped.
Substep B5: the compensation value calculation process for this rate ends.
Step 204: and when the power value corresponding to the output power calibration data is within a preset power threshold interval, storing the output power calibration data, and determining that the product to be tested corresponding to the output power calibration data is a qualified product.
Wherein the preset power threshold region is: -1.5 db mw to 1.5db mw.
The data range corresponding to the first preset power adjustment parameter includes the data range corresponding to the second preset power adjustment parameter.
In this application, assuming that K is a difference between a current power test value (denoted as PR) and a target power value (denoted as PT) at a certain rate, K = PR-PT, a power compensation value for a channel group is denoted as TdBm, and a power fine adjustment value for a single rate of each channel in the channel group is denoted as RdBm
|T|≤1.5dBm (1)；
|R|≤0.7dBm (2)；
The determination conditions of good products (power meeting expectations) are: the difference between the power value (actually measured power) corresponding to the output power calibration data and the target power is not more than +/-1.5 dBm, namely, the good product must meet the following conditions:
|K+T+R|≤1.5dBm (3)；
the determination conditions of defective products (excessive power deviation of single rate) are: the difference value between the actual measurement power and the target power of a single speed is larger than 5dBm, namely | K | is larger than 5dBm, otherwise, good products must meet the requirement
|K|≤5dBm (4)。
Step 205: and under the condition that the power value corresponding to the output power calibration data is not within the preset power threshold interval and the power value corresponding to the output power calibration data is smaller than or equal to a preset exit test power threshold, returning to the step of performing power calibration on the data to be calibrated corresponding to each channel group according to a first preset power adjustment parameter to obtain a first power compensation value, and performing power compensation again.
The preset exit test power threshold is: 5db mw.
Step 206: and if the power value corresponding to the output power calibration data is within a preset power threshold interval within the preset return times, storing the output power calibration data.
And if the return times are greater than the preset return times and the power value corresponding to the output power calibration data is not within the preset power threshold interval, determining that the product to be tested corresponding to the corresponding data to be calibrated is a defective product.
The radio frequency power calibration method can realize maximum energy transmission of Radio Frequency (RF) signals, is low in cost, high in reliability and good in consistency, and can reduce the radio frequency debugging period of a development end.
For example, 13 channels are 2.4G, channels 1-4 are divided into a first channel group (Band 0), channels 5-9 are divided into a second channel group (Band 1), and channels 10-13 are divided into a third channel group (Band 2), and the transmitting units of each channel group are independent and do not affect each other, so that only a calibration test needs to be performed on each channel group, and more than three times of calibration terms can be reduced, thereby improving efficiency, wherein the calibration range of each channel group is ± X decibel milliwatts (dBm). In this application, taking a certain set of data collected during the power calibration actual measurement process of the first channel group Band0 as an example, the power calibration method process described in this application is further described in detail:
first, the target power values of the rates of all channels in the first channel can be obtained through the instrument test, as shown in table 1 below:
TABLE 1
Before calibration, a set of data of power deviation K from the target power for all rates obtained by device power detection is shown in table 2:
TABLE 2
If the absolute value of K is larger than 5dBm and the absolute value of Kmax-Kmin is larger than 4.4dBm, the product is not defective. Wherein, kmax = -2.6dBm, kmin = -1.9dBm, | Kmax-Kmin | =0.7dBm.
Calculating a compensation value of Band 0: b = (Kmax + Kmin)/2 = (-2.6-1.9) = -2.2dBm; the value of Kmax + Kmin/2 is not more than or equal to 1.0dBm, and the emission power value of Band0 needs to be continuously adjusted.

TABLE 3
If no, | K | >5dBm and | Kmax-Kmin | >4.4dBm occur, it is not bad, where Kmax =1.7dBm, kmin =0.1dBm, | Kmax-Kmin | =1.6dBm
Calculating a compensation value of Band 0: b = (Kmax + Kmin)/2 = (1.7 + 0.1) =0.9dBm; satisfy the requirement of
And if the ratio of (Kmax + Kmin)/2 is less than or equal to 1.0dBm, the emission power value of Band0 does not need to be continuously adjusted.
However, there are rates (802.11g 6 Mbps) that do not satisfy | K | ≦ 1.5dBm, and the transmit power value for that rate needs to be adjusted continuously. Wherein, | K | = | K | -1.5=1.7-1.5=0.2dbm.
Performing power calibration on a single channel in each channel group based on a second preset power adjustment parameter to obtain a second power compensation value, calibrating the first power calibration data based on the second power compensation value to obtain output power calibration data, adjusting the transmission power value of-0.2 dBm in the 802.11g6Mbps rate mode of the device, enabling the transmission power value to take effect, and reacquiring data of power deviation K at all rates under channel 1 in Band0 as shown in table 4:
TABLE 4
Wherein Kmax =1.2dbm, kmin =0.1dbm, | Kmax-Kmin | =1.1dBm.
If the conditions that (Kmax + Kmin)/2 | is less than or equal to 1.0dBm and | K | of all the rates is less than or equal to 1.5dBm are met, the calibration process is finished and the calibration is successful.
The calibration parameters of the device obtained this time are as follows: band0 calibration parameters: +2.2dBm; parameters were calibrated in 802.11g6Mbps rate mode: 0.2dBm, other rate modes do not require calibration.
