Description
Technical field
The invention relates to ultrasonic thickness measurement scanning display technique, is a kind of ultrasonic thickness measurement instrument B-type scanning and display method and audiogage thereof specifically.
Background technology
Audiogage is the instrument that carries out thickness measure according to the ultrasonic pulse principle of reflection, when the probe ultrasonic waves transmitted pulse of audiogage arrives two kinds of different materials interphases by testee, pulse is reflected back toward probe, and the time of propagating in material by accurate measurement ultrasound wave is determined the thickness of measured material.
Waveform shows that class (A sweep, B scanning) audiogage is a class in the audiogage series of products.Type B shows with respect to amplitude modulation(PAM) A type to show it is that a kind of briliancy modulation shows, can show the cross section figure by mobile straight line of probe and the decision of probe transmit beam axis.Its horizontal ordinate shows the position of probe, and ordinate shows the propagation distance of probe launching beam, i.e. the degree of depth of measuring workpieces, and Type B shows can be converted into the thickness reading understandable X-Y scheme.
Please refer to Fig. 1, be a kind of Type B audiogage, it includes fuselage 11, liquid crystal display 12, keyboard 13, probe 14, receiver socket 15, emission socket 16.Its ultimate principle probe 14 emission ultrasonic pulses of serving as reasons arrive testees and propagate in object, are reflected back toward probe when arriving material interface, determine the thickness of measured material by the accurate travel-time of measurement ultrasound wave in material.By keyboard 13 input instructions, transmit to visiting first by emission socket 16, feed back to processing unit by probe emission ultrasonic pulse and with the ultrasonic pulse reflected signal by receiver socket 15, signal is shown by liquid crystal display 12 through the data that processing obtains.
Please refer to Fig. 2, theory diagram for existing audiogage, wherein, give processing unit 21 by keyboard 23 input instructions, extremely pop one's head in by processing unit control radiating circuit 24 output electric pulses, the excitation piezoelectric chip produces pulse ultrasonic wave, ultrasound wave forms repeatedly reflection between the testee upper and lower surface, reflection wave is transformed into electric signal through piezoelectric chip, after amplification integeral type circuit 26 amplifies integer, be sent to sample circuit 27, read and be sent to processing unit after the measurement data in the sample circuit 27 and handle, and export end product to LCDs 22.
Lcd technology has adopted the mode of " active-matrix " to drive.Method is the electric crystal electrode that utilizes thin film technique to make, and utilizes method for scanning " on one's own initiative " to control the Push And Release of any one display dot.Upwards appear by following Polarizer earlier during light source irradiation, by the liquid crystal molecule conducting light.During electrode conduction, the Liquid Crystal Molecules Alignment state can change, and reaches the purpose of demonstration by shading and printing opacity.Because transistor has capacity effect, can keep potential state, the liquid crystal molecule of printing opacity can keep this state always, till electrode powers up its arrangement mode of change next time again.Liquid crystal all is provided with a semiconductor switch for each pixel, because each pixel can directly be controlled by a pulse, the display driver time of all pixels has determined the refreshing frequency and the response time of liquid crystal display.
Because it is to adopt from left to right or visual from right to left method of passing that B-scan shows, need constantly refresh the viewing area, traditional design adopts passing method in display buffer to realize that scanning shows, data translation and liquid crystal display are carried out in whole display buffer, need pass the display buffer data, carry out liquid crystal display simultaneously, data are passed process as shown in Figure 3.
Adopt the display buffer to carry out data translation and liquid crystal display method, need to drive a fairly large number of semiconductor switch, limited the refreshing frequency and the response speed of liquid crystal display.
