For ease of the effect your auditor understands technical characteristic of the present invention, content and advantage and can reach, hereby the present invention is coordinated accompanying drawing, and be described in detail as follows with the expression-form of embodiment, and wherein used accompanying drawing, its purport is only the use of signal and aid illustration book, may not be actual proportions after the invention process and precisely configure, therefore should not understand, limit to the interest field of the present invention on reality is implemented with regard to the ratio of not appended accompanying drawing and configuration relation.
Refer to Fig. 1, it is the module map of the detection system detecting voltage that automatically switches of the present invention.In figure, this detection system detecting voltage that can automatically switch includes proving installation 1 and graphics calculations device 2, and graphics calculations device 2 is connected to proving installation 1.This invention is main when being that graphics calculations device 2 performs ADC Calibration, automatically can switch the different voltages provided needed for it, thus design this proving installation 1.In general, graphics calculations device 2 needs when ADC Calibration to carry out sampling ADC by 3.0 volts (v) and 4.0 volts (v) two voltages, and this proving installation 1 just automatically can switch to second voltage 12 of first voltage 11 of 3.0v or 4.0v to be supplied to graphics calculations device 2 according to instruction.Wherein, when graphics calculations device 2 performs Analog-digital Converter calibration procedure 21 (ADC Calibration), by transmission first test instruction to proving installation 1.Proving installation 1 just can export the first voltage 11 to graphics calculations device 2 according to this first test instruction, and whether proving installation 1 presents detect the first voltage 11 exported in steady state (SS), if, then transmit one and stablize information to graphics calculations device 2, allow graphics calculations device 2 according to this stable information and performed the first stage calibration procedure 211 in Analog-digital Converter calibration procedure 21 by the first voltage 11, namely the voltage sample calibration of 3.0v.Then, transmission second test instruction to proving installation 1, makes proving installation 1 export the second voltage 12 to graphics calculations device 2 according to the second test instruction by graphics calculations device 2, and detects whether the second voltage 12 exported is stable dress state.To transmit in proving installation 1 after stable at the second voltage 12 and stablize information to graphics calculations device 2, foundation is just stablized information and is performed the subordinate phase calibration procedure 212 in Analog-digital Converter calibration procedure 21 by the second voltage 12 by graphics calculations device 2, namely the voltage sample calibration of 4.0v.
In above-mentioned, graphics calculations device 2 is when performing first stage calibration procedure 211 and subordinate phase calibration procedure 212 respectively, the first calibration voltage value and the second calibration voltage value will be produced respectively, and judge whether the first calibration voltage value and the second calibration voltage value meet the first calibration range and the second calibration range respectively further.If so, graphics calculations device 2 will produce the first calibration information and the second calibration information calibrating and pass through respectively; If not, then the first calibration information calibrated unsuccessfully and the second calibration information is produced respectively.Wherein, graphics calculations device 2 can optionally produce the second test instruction according to the first calibration information after executing first stage calibration procedure 211, with so that determine whether also to continue to perform follow-up subordinate phase calibration procedure 212.Possible situation is: when calibrating the first calibration information unsuccessfully if be produced as, and 2, graphics calculations device does not produce the second test instruction, now by end simulation digital conversion calibration procedure 21 immediately, and is shown by the first calibration information and stores.Or no matter the first calibration information is for calibrating failure or passing through, graphics calculations device 2 all produces the second test instruction; Now graphics calculations device 2 will store the first calibration information in advance, then after executing subordinate phase calibration procedure 212, show the first calibration information and the second calibration information (the first calibration information is for calibrating unsuccessfully) more in the lump, or (the first calibration information is that calibration is passed through only to show the second calibration information, again the second calibration information is stored, and end simulation digital conversion calibration procedure 21.
At this, carry out the above-described testing calibration mode of brief description with a citing, two detection schemes can be divided into, one: graphics calculations device 2 sends the first instruction of test 3v voltage to proving installation 1.Proving installation 1 accepts instruction, and provide first voltage 11 of 3v to tested circuit board, after proving installation 1 detects the 3v voltage stabilization be output, feedback stable information is to graphics calculations device 2, graphics calculations device 2 is made to detect tested circuit board, sampling ADC by computing to produce the first calibration voltage value, and judge whether this first calibration voltage value meets one first calibration range, such as be greater than 2.94v and be less than 3.07v, and then be produced as by (pass) or the first calibration information of failure (fail) and store this information.If what obtain is fail situation, detection of end is also misrepresented deliberately, and what obtain is the situation of pass, and graphics calculations device 2 sends the second instruction of test 4V voltage to proving installation 1, and proving installation 1 accepts instruction, provides 4v second voltage 12 to tested circuit board.After proving installation 1 detects the 4V voltage stabilization of output, feedback stable information is to graphics calculations device 2 again, graphics calculations device 2 is made to detect tested circuit board, sampling ADC by computing to produce the second calibration voltage, and judge whether this second calibration voltage value meets one second calibration range, such as be greater than 3.92v and be less than 4.09v, and then be produced as the second calibration information that voltage calibration is pass or fail and store this information, show this second calibration information and detection of end simultaneously.
In addition, its of above detection scheme two is: if graphics calculations device 2 is when testing 3v voltage and occurring fail information, then store first calibration information of this fail, and continues to detect 4v.After 4v is completed, show the first calibration information and the second calibration information more in the lump, so, as long as detection operator is checked in 3v or 4v test phase after 4v test terminates in graphics calculations device 2 occur mistake, and then can mistake differentiation be carried out to circuit board rapidly and repair.
