Background
In the field of PON product production calibration, PON products designed based on WIFI all need to calibrate a series of parameters of the WIFI to ensure the communication performance of the products. While WIFI power calibration is a very important part of it.
Most of the DACs (analog-digital converters) (digital-analog converters) of the WIFI are linear, that is, under a set DAC (analog-digital converter) value of the function, the WIFI emits corresponding laser power, and when the DAC (analog-digital converter) value is increased, the emission power is increased. When the DAC (analog-digital converter) value is reduced, the corresponding actual power is reduced, so that the power calibration of the WIFI can be realized by repeatedly increasing and decreasing the DAC (analog-digital converter) for many times through the comparison between the target power and the actual power, and the WIFI laser emission power of the product is in a target range.
For the non-linear WIFIERP database, the DAC (analog-digital converter) value for controlling the WIFI power is used to control a register similar to a group of resistors connected in parallel, so that the DAC (analog-digital converter) value changes in a jumping manner according to the required resistance value, and at this time, the DAC (analog-digital converter) cannot be increased or decreased in a linear calibration manner to achieve the purpose of increasing or decreasing the power, and finally controlling the power in the target range.

The following embodiments of the present application describe the scheme of the present application in detail by taking a WIFI power calibration method as an example, but the scope of protection of the present application is not limited by the embodiments.
As shown in fig. 1, the present invention provides a WIFI power calibration method, which includes the following steps:
step 1: and importing the WIFI calibration parameters into an ERP database to realize the binding of the WIFI calibration parameters and product serial numbers, wherein each product serial number corresponds to a product ID.
In the WIFI power calibration method provided by the embodiment of the invention, WIFI calibration parameters are imported into an ERP database before production of a product, wherein the imported data comprise calibrated target power, frequency offset and the like.
Step 2: and loading the analog-digital converter of the product and the corresponding actual power into an ERP database, and forming a lookup table according to the product ID.
In the WIFI Power calibration method provided by the embodiment of the invention, for loaded DACs (analog-digital converters) and corresponding actual powers, products are sequenced according to the actual powers corresponding to the analog-digital converters in the order from small to large of the actual powers, and reordering is avoided during each loading, so that the IDs of the products are sequenced as the actual powers of the products are sequenced from small to large, and a lookup table based on the ID sequencing of the products is generated, the lookup table realizes recording of the IDs of the products and the approximate linear relation between the corresponding powers and the actual powers, and the calibration feasibility is changed into reality by correspondingly increasing or decreasing the actual powers transmitted by the WIFI of the products.
And step 3: and inquiring the register parameters of the corresponding product according to the lookup table, and setting the initial value of the register.
In the WIFI power calibration method provided by the embodiment of the invention, the initial value of the register power of the router is set through a Telnet protocol, the corresponding WIFI parameter is inquired according to the product serial number (because the binding between the product serial number and the WIFI serial number is completed before, the WIFI parameter can be inquired through the product serial number), and the product ID is obtained.
And 4, step 4: and the initial value of the register is changed through a Telnet protocol to obtain the power of the new analog-digital converter.
In the WIFI power calibration method provided by the embodiment of the invention, according to the target power to be configured, namely the power range of the WIFI of the product, which needs to be calibrated actually, the register value is changed through the Telnet protocol, so that the power of the WIFI is calibrated, when the DAC power (analog-digital converter) value is reduced, the corresponding actual power is reduced, and thus the power of the WIFI can be calibrated by repeatedly increasing and decreasing the DAC power (analog-digital converter) through the comparison of the target power and the actual power.
And 5: and reading the power of the new analog-digital converter, judging whether the power reaches the standard, and predicting the initial value of the register of the next line.
In a possible implementation manner, the modified value of the initial value of the register corresponding to the target power to be configured is set in a register of a calibrated product to obtain a new power of the analog-digital converter, the new power of the analog-digital converter is obtained, the new power of the analog-digital converter is compared with the initial power, when the actual power falls within the range of the target power to be configured, the calibration is completed, the step 6 is skipped, otherwise, the calibration is required to be continued, and the step 5 is skipped;
step 6: calculating a slope and predicting and calculating a DAC power (analog-to-digital converter) of a next channel, returning to step 5, calculating a power difference from a current power of the current channel to a last power of the current channel, calculating a next DAC power (analog-to-digital converter) value from the power difference and the slope, since the DAC power (analog-to-digital converter) value is non-linear, calculating a DAC power (analog-to-digital converter) test value instead of writing a DAC (analog-to-digital converter) power value;
in one possible embodiment, after the first setting of the DAC power (adc), the actual power is read for the first time, at which point the next tested DAC power (adc) value is calculated using the empirical slope since there is no comparable actual power for the previous time;
in one possible embodiment, in addition to setting the DAC power (analog-to-digital converter) for the first time, the current actual power is read after setting the DAC power (analog-to-digital converter) each time; subtracting the actual power of the current time from the actual power of the last time, and dividing the actual power by the difference value between the DAC power (an analog-digital converter) to calculate an approximate slope (the approximate slope is not accurate, because the DAC power value and the power are in a logarithmic relation and not in a linear relation, but the time is gradually reduced in each approximation, and the approximate linear relation is obtained); then calculating the DAC power (analog-digital converter) value of the next test according to the difference value of the target power and the current power and the slope;
and 7: the power DAC power (analog to digital converter) value is saved, calibration is complete and exit.
