Abstract
Number of alarm indicator lamp equal to number of channel is setup on display screen. Each alarm indicator lamp is to a corresponding channel. Characters are that there is at least one base line on display screen to show waveform of combining detected results from two channels. Concretely, in each stated time interval, using same frequency samples detected results from two channels so as to obtain two pieces of array; then two pieces of array combined into a new array; the new array is sent to display, and one base line shows the result. Advantages are: display screen can display detected results from more channels, suitable higher requirement of increasing distinguishable channels, not increasing working strength of defect detecting operator.
Description
Technical field
The present invention relates to ultra-sonic defect detector, specifically, relate to a kind of display packing of multiple path ultrasonic flaw detector.
Background technology
Existing multiple path ultrasonic flaw detector for whether the various piece to detected object has the hurt situation detects simultaneously, its each passage is worked simultaneously, and on display screen, show and the corresponding waveform of testing result, the corresponding baseline waveform of passage, on display screen, be provided with simultaneously the quantity alarm lamp identical with number of channels, the corresponding passage of each alarm lamp, the flaw detection worker will monitor the waveform and the alarm condition of all passages simultaneously in testing process.Along with the raising that flaw detection requires, the passage of defectoscope increases, and so just must show more multichannel waveform on screen, but on limited screen, show too much wavy line simultaneously, not only realize difficulty, and will make each wavy line be difficult to distinguish, increase flaw detection worker's working strength.For example the steel rail ultrasonic flaw detecting instrument that uses is at present worked simultaneously with 5 passages, and shows testing result with 5 baseline waveform on display screen; As railway speed increase, need 9 passages to work simultaneously and could satisfy the flaw detection requirement, the waveform that must on display screen, show 9 passages, if continue to adopt existing display packing, the testing result that shows a passage with a baseline waveform, then must on display screen, show 9 wavy lines simultaneously, not only realize difficulty, and be difficult to distinguish.
Summary of the invention
The display packing that the purpose of this invention is to provide a kind of multiple path ultrasonic flaw detector makes display screen can accurately show more multichannel testing result, is easy to again realize and distinguish.The technical scheme that adopts is as follows:
A kind of display packing of multiple path ultrasonic flaw detector, on display screen, be provided with the quantity alarm lamp identical with number of channels, the corresponding passage of each alarm lamp, it is characterized in that: have at least a baseline to show the merging waveform of the testing result of two passages on the display screen, be specially, in each certain time interval, with same frequency the testing result of two passages is sampled respectively, obtain two arrays, then two number groups are merged into a new array, new array is flowed to display, show by a baseline.Two passages that can merge demonstration should meet the following conditions: the head angle of (1) two passage equates, such as all being 70 °; The attribute of (2) two passage detected object (as material, detection position, shape etc.) unanimity.
When preferably two number groups being merged into a new array, corresponding two data in more above-mentioned one by one two arrays are got wherein new array of numerical value the greater composition, and the waveform that baseline shows is the envelope waveform of two passages.During flaw detection, echo was strong when flaw detection object hurt was big, hurt hour echo is less, therefore select the wherein bigger numerical value of numerical value, can make baseline demonstrate the bigger testing result of hurt in two passages, and the less testing result of covering hurt, baseline waveform reflects the hurt situation of the object of detecting a flaw on sizable degree, reach the flaw detection purpose.
When the corresponding baseline waveform of passage, after the testing result of passage sampled, the array that obtains directly flowed to display, shows that by a baseline this part is a prior art; When baseline waveform of two passages correspondences, two number groups are merged into after the new array, and the process that is shown by display is identical with the situation of " a corresponding baseline waveform of passage ", belongs to prior art, is not described in detail at this.
The baseline number of the merging waveform of the testing result of two passages of above-mentioned demonstration determines according to actual conditions, situation about should consider comprise display screen size, total number of channels, can merge demonstration passage to (two passage form a passage to) number.
When display shows, be one group with per 3 baselines, press baseline group number with the display screen subregion, one group of baseline shows that at a subregion of display screen 3 baselines of same subregion are represented with blue, green, redness respectively.
The present invention is owing to be provided with alarm lamp on display screen, indication detects the passage of hurt, erroneous judgement therefore can not occur; Because echo is strong when big, hurt hour echo is less for hurt, therefore get in two arrays numerical value the greater in corresponding two data, forms a new array, can demonstrate the wherein bigger situation of hurt, cause the worker's that detects a flaw attention easily, can avoid omission; Owing to exist a baseline to show the situation of the testing result of two passages, therefore be easy to be implemented in and show more multichannel testing result on the limited display screen, both adapt to higher flaw detection and required (increase passage), be easy to difference again, and can not increase flaw detection worker's working strength.
Description of drawings
Accompanying drawing is the display interface synoptic diagram of the display screen of one embodiment of the present invention.
Embodiment
Accompanying drawing is expressed a kind of display screen of 9 passage steel rail ultrasonic flaw detecting instrument, on this 9 passage steel rail ultrasonic flaw detecting instrument 6 passages the (the 1st is arranged, the 1A passage, the 2nd, 2A passage and the 3rd, the 3A passage) 6 directions of rail head is detected, the probe of 6 directions of rail head is pressed a left side, in, part into three groups on the right side, wherein every group carry out respectively by 2 probes before, to detection afterwards, the corresponding passage of each probe, the 1st, the 1A passage is one group, the 2nd, the 2A passage is one group, the 3rd, the 3A passage is one group, in each certain time interval, with same frequency the testing result of two passages in same group is sampled, obtain two arrays, compare corresponding two data in two arrays then one by one, get wherein new array of numerical value the greater composition, for example one of them array is [100,100,95,89,73,65,20,3,3,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,3,20,85,80,15,2,0,0,0,0,0,0,0,0,0,0,0,0,0 ... ], another array is [100,98,97,81,77,62,10,2,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,5,28,91,82,10,5,3,0,0,0,0,0,0,0,0,0,0,0,0 ... ], then new array is [100,100,97,89,77,65,20,3,3,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,5,28,91,82,15,5,3,0,0,0,0,0,0,0,0,0,0,0,0 ... ], new array is flowed to display, on display screen, show by a baseline, therefore can show the testing result waveform of these 6 passages with 3 baselines; The respectively corresponding baseline of 3 passages in addition (the 4th, 5,6 passage).The waveform that therefore can show 9 passages with 6 baselines.
