Description
Technical Field
The invention belongs to the technical field of product performance testing, and particularly relates to a data analysis-based ONT power calibration method.
Background
In the development of modern society, users have higher and higher requirements for communication bandwidth, but at present, FTTH (fiber to the home) is still the optimal wired broadband solution, the market demand for ONT (Optical network termination) is also explosive growth, and ONT also becomes the most main production product of production type enterprises in the internet communication industry, so for a factory, the market competitiveness can be improved by producing ONT with high quality and low cost, and as the manpower cost is continuously increased, the production testing efficiency and automation are the basic requirements in the current environment. Based on the consideration of cost, currently, the mainstream ONT products all adopt a bob (bosa on board) scheme, and basically adopt an APD avalanche photodiode as a receiving end optical component, but the APD avalanche photodiode has a nonlinear characteristic, so that the conventional calibration method in a linear manner hardly meets the requirement of calibration accuracy.
Currently, the mainstream optical power calibration methods generally include the following two methods:
1. the dichotomy comprises the following steps:
s1: the ONT register is preset with an initial setting value X and a stepping Y, and the specific numerical values of X and Y are specifically determined by the technical personnel in the field according to production experience and actual conditions, and the invention is not limited;
s2: reading the ONT power through an optical power meter and comparing the ONT power with a standard value, finishing calibration if the measured value is in the range of the standard value, wherein the measured value at the moment is a target power value, and the set value at the moment is a target set value; if the measured value is not within the standard value range, the process proceeds to step S3;
s3: if the measured value is larger than the standard value, the set value is reset into the register after subtracting Y; if the measured value is smaller than the standard value, the set value is added with Y and then is reset into the register;
s4: reading the ONT power through an optical power meter and comparing the ONT power with a standard value, finishing calibration if the measured value is in the range of the standard value, wherein the measured value at the moment is a target power value, and the set value at the moment is a target set value; if the measured value is not within the standard value range, the process proceeds to step S5;
s5: if the measured value is larger than the standard value, the set value is reduced by Y/2 and then reset into the register, and the step S4 is returned; if the measured value is smaller than the standard value, the set value is reset to the register after adding Y/2 and the step returns to step S4.
2. And (3) simulating a linear relation, measuring a part of data to give a reference linear relation in a research and development stage in advance, calculating an empirical value through the linear relation during production, and finely adjusting according to actual conditions and small steps.
In practical situations, due to the high sensitivity of the optical device, the calibration values are greatly influenced by material batches and environments, the final target value of each ONT is found to be very large through production data analysis, the final target value can be found only by continuously and repeatedly calibrating by using the two methods, and the production testing efficiency is greatly reduced under the condition of more than 10 times in extreme cases.
Disclosure of Invention
The invention aims to provide a method for calibrating ONT power based on data analysis, aiming at the defects of the prior art, so as to find a target value at the fastest speed, improve the production test efficiency and reduce the production cost.
In order to solve the problems, the technical scheme adopted by the invention is as follows:
a method of data analysis based ONT power calibration, comprising:
s1: an initial set value X is set in advance in an ONT register1And step Y, obtaining initial power P through a production measuring platform1， X1And P1Form a data set R1The production measuring platform is based on the data set R1Sending a target data reading request to a server;
s2: the server receives the target data reading request and inquires whether a data group R exists in a server database1；
S21: if no data set R exists1Then, the production testing platform is recovered, and the production testing platform calibrates the power of the ONT by using a dichotomy to obtain a target power value P2And a target set value X2，X2And P2Form a data set R2Production measuring platform handle R1And R2The composition correspondence is sent to the server, which sends R1And R2Storing the binding relationship in a database, adding a flag bit in the database, and making the flag bit into 1;
s22: if there is a data set R1If the power value Px is not the same as the power value Px, the server sends a target data group Rx with the highest flag bit data to the production and measurement platform, the production and measurement platform obtains a target set value Xx in the data group Rx, and the target set value Xx is written into an ONT register and the power value Px at the moment is read through the production and measurement platform;
s221: if Px meets the standard value, the test platform tests PASS, and the set value and the power value of the register at the moment are recorded as X3And P3，X3And P3Form a data set R3Production measuring platform handle R1And R3The composition correspondence is sent to the server, which sends R1And R3Storing the binding relationship in a database, if the data in the database does not exist, marking 1, and if the data in the database already exists, adding 1 to the marking;
s222: if the measured power Px is greater than the standard value, the target set value Xx is gradually decreased in a small stepIf the measured power value Px is smaller than the standard value, gradually increasing the target set value Xx in a small step to make the measured power value Px meet the standard value, and recording the set value and the power value of the register at the moment as X4And P4，X4And P4Form a data set R4Production measuring platform handle R1And R4The composition correspondence is sent to the server, which sends R1And R4Storing the binding relationship in a database, if the data in the database does not exist, marking 1, and if the data in the database already exists, adding 1 to the marking;
s3: a calibration of the next ONT is performed.
The further technical scheme is that when a certain step is continuously executed for more than N times during the calibration of the same ONT, the calibration FAILs, and the production test platform prompts FAIL.
In the method, the flow of dichotomy calibration is mainly used for execution at the beginning to obtain enough data samples, and when the number of the data samples is increased, the test is executed basically according to the flow of searching the target value of the samples, so that the efficiency is greatly improved.
Through data research, it is found that although optical devices are very sensitive and wireless, in the same design scheme, when the same batch of materials are produced, the presented characteristics are very similar, even most of the materials are completely consistent, and the production is carried out in large batch, and the characteristics of the batch of data can be determined by calculating the calibration data of dozens of ONTs before each batch of orders, so that the target value of ONTs in subsequent production can be quickly calculated.
