Description
Technical field
The present invention relates to a kind of ultrasound examination Scanning speed measuring method.
Background technology
Ultrasound examination Scanning speed≤150mm/s is specified in JB/T4730-2005 " bearing device Non-Destructive Testing " standard, once exceed this velocity constraint in detection, coupling then can be caused bad or teaching machine frequency acquisition is too low, show as waveform display not exclusively, the more serious waveform that causes is lost, and seriously reduces the fiduciary level of ultrasound examination.Current ultra sonic machinery scanning equipment realizes Scanning speed by the translational speed controlling mechanical scanning frame and is no more than limit value, but to the manual pulse-echo ultrasound wave detecting method that scene uses in a large number, present stage does not have control measure.Therefore be necessary to invent a kind of new method to measure, limit Scanning speed when manual ultrasonic detects.
Summary of the invention
Object of the present invention is just to provide a kind of ultrasound examination Scanning speed measuring method, utilizes this patent method can measure the Scanning speed of probe when manual ultrasonic detects; And can the real-time Scanning speed gathered be presented on digital ultrasonic flaw detector, realize overspeed alarming function, the limit value making Scanning speed be no more than standard to specify.
the present invention adopts following technical scheme:
Its method step of a kind of ultrasound examination Scanning speed of the present invention measuring method is as follows:
(1) probe system is connected: the instrument that will test the speed is connected with probe, makes it to be no more than limit value with monitoring probe translational speed; Require that probe is consistent with the instrument moving parameter that tests the speed; And the instrument that tests the speed realizes signal transmission and power supply by probe interface and ultra-sonic defect detector;
(2) detection system is connected: be connected with probe by connecting line by ultra-sonic defect detector; Realize the signal transmission of ultra-sonic defect detector and probe; Realize ultra-sonic defect detector and the signal transmission of instrument and the power supply of testing the speed;
(3) detected parameters is checked in adjustment, and the precision especially tackling knotmeter is checked.
(4) detect: probe system detects at examined workpiece, the instrument that tests the speed is by the collection of probe translational speed and be passed to ultra-sonic defect detector, ultra-sonic defect detector panel shows Scanning speed, when actual Scanning speed exceedes Scanning speed limit value, then sound and light alarm.
principle of the present invention is:
The present invention utilizes velometer to measure the translational speed of probe when manual ultrasonic detects; The real-time Scanning speed signal gathered is inputed to digital ultrasonic flaw detector; Ultra-sonic defect detector shows in modes such as curves and records omnidistance probe translational speed, and arranges overspeed alarming, if report to the police, then staff rechecks after reducing Scanning speed.Detection system should possess following condition:
(1) selection of velometer:
Should preferably precision is high, volume is little, weight is little velometer, can fix or not be fixed on probe, not affect the movement of the probe when detecting for principle.Select grating velometer herein.Its principle is in rotating shaft, install coaxial grating wheel, and light transmitting and optical receiver are equipped with in grating wheel two ends, during work, optical transmitting set is in emission state always, the light signal that the rotation of grating wheel makes receiver receive is discontinuous light pulse, and axle rotates faster, and pulsed frequency is higher.Receiver is converted into electric signal light pulse, i.e. digital pulse signal, and processor, according to this pulsed frequency, calculates the rotating speed of rotating shaft, and then can draw the translational speed of probe.Require that the processing power of velometer frequency acquisition and processor should meet the acquisition and processing of the translational speed to probe herein.
(2) research and development of ultra-sonic defect detector New function:
Ultra-sonic defect detector after research and development should have following New function: 1. the signal that can read and process velometer, shows and record the translational speed of probe with curve or other forms, and staff can know the translational speed of probe while detecting; Prison inspection personnel also can transfer probe translational speed curve to judge whether Scanning speed transfinites.2. can realize overspeed alarming, Scanning speed gate is set with standard-required, when actual Scanning speed exceedes gate, then report to the police.
beneficial effect of the present inventionfor:
This patent method can measure the Scanning speed of probe when manual ultrasonic detects; And can the real-time Scanning speed gathered be presented on digital ultrasonic flaw detector, realize overspeed alarming function, the limit value making Scanning speed be no more than standard to specify.Utilize this invention can realize measurement and the restriction of Scanning speed when manual pulse-echo ultrasound ripple detects.The unfavorable factor such as avoid bringing because Scanning speed is too fast bad the or teaching machine frequency acquisition of probe coupling too low.
