This detection device can the accuracy treat measure and monitor the growth of standing timber material surface and inside various defect reliably, if: welding seam, crackle, inclusion, gas pocket etc. Detect. The utility model discloses utilized virtual instrument's advantage and relevant data signal processing technique, various metals, the combined material that can be directed against specially in the environment such as laboratory, industrial production processing carry out ultrasonic non -destructive testing.
Description
Technical field
The utility model belongs to industrial ultrasonic technical field of nondestructive testing, relate to a kind of device various material being carried out to Ultrasonic Nondestructive in the industrial circles such as machine-building, petrochemical complex, railroad track, Rail car manufacture, Aero-Space, particularly a kind of ultrasonic nondestructive testing device based on virtual machine.
Background technology
Ultrasonic Nondestructive refers under the prerequisite not damaging starting material physical characteristics and duty, use ultrasound wave to can not visual test to material surface and a kind of detection means of checking of inside.The principle of ultrasound examination is: if there is the defect such as snotter, crackle, layering, pore in material, when ultrasonic propagation is to the interface of material and defect, will generating portion or all reflect, the ultrasonic echo reflected receive by ultrasonic probe, by the processing of circuit (A/D conversion etc.) of instrument internal, the display screen of instrument will demonstrate the waveform of differing heights and a determining deviation, now, engineering technical personnel just can according to the variation characteristic determination defect position in the material of waveform, the degree of depth, size and shape.The advantage of Ultrasonic Nondestructive is that it is harmless, detect that thickness is large, highly sensitive, speed is fast, cost is low, but also can position the defect in material and quantitatively.
Traditional ultrasound examination normally testing staff's manual operations, judgement and record.This just needs testing staff to move back and forth on detected materials surface detection with ultrasonic probe, and in testing process real time record ultrasonic echo waveform signal defect waves is analyzed and judges.But this traditional detection mode affects by the factor such as technical merit, anxious state of mind of operating personnel, and testing result error even can cause the undetected of defect comparatively greatly.From another perspective, because the characteristic (as surface roughness etc.) of existing a lot of Ultrasonic Nondestructive equipment to material itself also has certain requirement, the data of the data and sample material itself which results in actual measurement have deviation.
Summary of the invention
The purpose of this utility model is to provide a kind of ultrasonic nondestructive testing device based on virtual instrument, improves the work efficiency of Ultrasonic Nondestructive, accuracy and reliability, reduces work difficulty and the labour intensity of testing staff.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of ultrasonic nondestructive testing device based on virtual machine, comprise industrial computer, tank and probe, capture card and LabVIEW virtual machine are installed in industrial computer, bottom of gullet is provided with sample dispenser, during use, in tank, inject water.
The utility model ultrasonic nondestructive testing device by virtual instrument diverse in function, highly versatile, cost performance is high, development difficulty is low, extendability is strong etc., and advantage is improved conventional ultrasonic wave the cannot-harm-detection device, structure is simple, easy to operate.Can accurately and reliably to detected materials surface and inner various defect, as: weld seam, crackle, snotter, pore etc. detect.The utility model make use of the advantage of virtual instrument and relevant signal processing technology, can manufacture in the environment such as processing carry out Ultrasonic NDT for laboratory, industry specially.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
As shown in Figure 1, the utility model the cannot-harm-detection device, comprises industrial computer 6, tank 2 and probe 1, is provided with LabVIEW virtual machine 5 and capture card 7 in industrial computer 6, industrial computer 6 is connected with the peripheral apparatus such as display, keyboard, and tank 2 bottom surface is provided with sample dispenser 3.
Capture card 7 adopts channel ultrasonic transmitting/receiving capture card, for hyperacoustic transmitting, reception carry out data processing.The digitizing of the transmitting of probe 1, reception and signal is realized by capture card 7.
Industrial computer 6 adopts the industrial computer with Full-size card Standard PC PCI interface.
During use: be fixedly mounted on by sample 4 on sample dispenser 3, then, in tank 2, water is injected, probe 1 is erected on tank 2, make probe 1 registration coupon 4, and make probe 1 stretch into underwater towards one end of sample 4, be communicated with probe 1 and industrial computer 6 by connection line 8.Open industrial computer 6, start industrial computer 6 by the driver that capture card 7 is equipped with, according to the requirement of sample, regulate correlation parameter by LabVIEW virtual machine 5, and realize the functions such as ultrasonic transmitting, reception, A/D conversion by LabVIEW virtual machine 5.In testing process, by regulating parameter adjustment probe 1 relative to the position of sample 4, the Scanning Detction that can carry out without dead angle to whole sample, realizes the complete detection of sample 4.Arrange by the parameters of the signal waveform in LabVIEW virtual machine 5 pairs of testing processes, process and analyze, obtain complete, Bottom echo and defect waves clearly.
Adopt clean water as couplant in the utility model the cannot-harm-detection device testing process, can prevent other factors from causing larger decay to sound wave, make detection more accurate.
The ultrasonic probe that probe 1 in this pick-up unit adopts water logging to detect a flaw, is used for transmitting and receiving signal, realizes the mutual conversion of electric signal harmony signal.
The utility model the cannot-harm-detection device is by LabVIEW virtual machine, apply it in traditional ultrasonic nondestructive testing device, multiple recording, in real time detection and real time record etc. are carried out to ultrasound echo signal, improve the reliability of detection efficiency and detection, solve the afunction problem that conventional ultrasonic wave instrument exists well.
The requirement detected along with industrial ultrasonic improves constantly, and uses LabVIEW virtual machine not only constantly can upgrade to ultrasonic nondestructive testing, and the construction cycle is short, save detection spending, difficulty is low, user interface is friendly.
