Row calibration and test, be also accomplished by efficient calibration algorithm and meet the needs produced in enormous quantities.
For different hardware designs, even with the various boards of same batch of hardware designs, need write
Calibration parameter be often different from, it is therefore desirable to every a piece of circuit board is all carried out wireless calibration, but due to
The channel and the test event that need calibration are the most, the longest, and how height of resurveying can be efficiently completed
Test, shortens the testing time, promotes production capacity, just becomes a problem needing to solve.
Summary of the invention
It is an object of the invention to provide a kind of calibration system based on wireless test and calibration steps thereof, solve existing
Some invalid calibration system and methods cannot adapt to the circuit board of different hardware design, also cannot adapt to same hardware
Design and the problem of different batches circuit board.
For solving the problems referred to above, the technical solution used in the present invention is:
A kind of calibration system based on wireless test,
Including main test PC, being used for testing product, during to register, based on the channel parameter of PC, value is sent to
Server；
Including server, for recording each channel difference each other, after receiving main test PC, record it
Channel is illustrated as basic value, and more difference between different channels, carries out the channel parameter of pair test PC
Calibration；
PC is tested including secondary, the channel parameter after calibrating for corresponding channel differences according to mistaken ideas device,
The product of same batch is tested.
Further, described main test PC is random or specify and choose from pair test PC.
A kind of calibration steps based on wireless test, comprises the following steps:
Step one, server record main test PC and all secondary test PC places channel difference each other；
Step 2, product is tested by main test PC, after being successfully tested, using this calibration parameter as base
Plinth value uploads onto the server and records and store；
Step 3, the calibration parameter basis value that server is uploaded according to main test PC, and main test PC and institute
There is secondary test PC place channel difference each other, the calibration parameter on all secondary test PC is adjusted；
Step 4, the product of same batch, according to the parameter after server calibration, is surveyed by all secondary test PC
Examination.
Further, described main test PC is random or specify and choose from pair test PC.
Use and have the beneficial effects that produced by technique scheme: by obtaining each channel differences from server,
Having only to calibrate a channel, the debugging initial value of other channels is obtained by mathematic interpolation, substantially increases tune
Examination First Pass Yield, decreases debugging number of times, thus significantly shortens the testing time, improve production efficiency.
