Fig. 2 is the data and curves of the actual test of the utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
As shown in Figure 1, the utility model comprises: master control circuit board 1, adopt the ARM-M3 system, this master control circuit board is integrated full spectral light photodetector, automatic gain amplifier (but automatic range conversion), high-speed AD converter and lithium battery power supply and administration module is used for detecting the intensity of illumination by automatic beam change welding mask filtrator.LED high-brightness signal generator and LED infrared signal trigger 2, wherein signal generator adopts white highlighted LED as incident light source, the infrared signal (wavelength is 950nm) that produces when LED infrared signal trigger is used for simulating welding makes it action thereby trigger automatic beam change welding mask filtrator.Sample detection box 3 is used to place the sample that will test.LCD 4 adopts 65K look, 320*240 LCD, the signal that is used to gather and the demonstration of measurement result.Computing machine 5, measurement data also can be connected to by USB interface and carry out stores processor on the computing machine; In the absence that computing machine connects, this utility model proving installation also can work alone.Whole testing device is used the built-in lithium battery power supply, charges by the USB mouth.
Principle of work, sample detection box 3 are between light source and the detecting amplifier, and test product is put into sample detection box 3.At first under LED high-brightness signal generator does not open the light the situation in source, at first do not detect light intensity one time, be used for regulating zero point automatically.Open LED high-brightness signal generator then and produce light source, detect the light intensity by automatic beam change welding mask filtrator behind the wait light stability, trigger LED infrared signal trigger then, the simulation welded condition makes the action of automatic beam change welding mask.Start high-speed A/D converter continuous acquisition conversion value simultaneously, full-automatic gain amplifier has multistage automatic gain regulatory function.Because the strong range of bright half-light of automatic beam change welding mask is very big, maximum can reach 10
5, base amplifier and AD do not have so high precision, therefore adopt the control of multistage amplification and automatic gain.During work, full-automatic gain amplifier is at first with minimum enlargement factor work, increases 10 times of gains when detecting signal automatically after less than minimum threshold, correctly detected up to signal.So can reach 10 through 2 ~ 3 grades of amplifications
5The signal rank.Obtain measuring curve, can calculate reaction time, i.e. reaction velocity by the variation of calculating intensity of illumination.
After finishing, assaying reaction speed at first closes LED infrared signal trigger, the simulation welding finishes, and starts the high-speed A/D converter acquired signal simultaneously, and this moment, gain amplifier was from maximum, after surpassing max-thresholds, reduce 10 times of gains automatically, finish obtaining measuring curve up to detection.Can calculate delay time by the variation of calculating intensity of illumination.
The course of work: test article is inserted in the detection box 3, begun test according to the step of setting.At first when not opening led light source, detect a surround lighting light intensity, be used for calibrating zero point automatically.Calibration is opened led light source after finishing, and detects the light intensity of passing through filter this moment, triggers LED infrared signal trigger then, and start the AD conversion simultaneously, and beginning continuous detecting light intensity, the AD acquisition resolution is 1uS, continuous acquisition time 10mS, analytical calculation reaction velocity then.The mistiming that drops to (T1) from trigger pip (T0) to light intensity at 10% o'clock is exactly the reaction velocity of automatic beam change welding mask filtrator.Stop infrared emittance after the reaction velocity test is finished, start AD once more and transform, more than the continuous acquisition light intensity signal 1S, analytical calculation recovers delay time.Rise to 90%(T3 from stopping to trigger (T2) to light intensity) mistiming be exactly delay time.
Fig. 2 is the data and curves of actual test, and time T 0 is the trigger point of reaction velocity, and T1 is that light intensity drops to 10% point.T2 is the end trigger point, and T3 is 90% point that light intensity rises to.Reaction velocity equals T1-T0, and delay time equals T3-T2.
Above-described only is preferred implementation of the present utility model, and the utility model is not limited to above embodiment.Be appreciated that other improvement and variation that those skilled in the art directly derive or associate under the prerequisite that does not break away from spirit of the present utility model and design, all should think to be included within the protection domain of the present utility model.
