Abstract
The invention provides a data acquisition process meeting both requirements of field flaw detection and playback flaw detection for steel rails and belongs to the field of flaw detection for steel rails. The technical scheme includes that a probe of a steel rail flaw detector can emit radioactive wave twice within an emission cycle, the radioactive wave reflected for the first time is received according to the flexibility set by flaw detection staff, and the received results are used for field flaw detection, so that alarm can be sent; the radioactive wave reflected for the second time is received according to the higher flexibility, and the received results are saved in a whole recorder and cannot be viewed by the flaw detection staff on field but can be viewed only when being played back. The data acquisition process has the advantages that two types of data are acquired by one work process of the flaw detection staff so that labor and materials are saved; and further, flaw detection capacity is improved, accidents of steel rails are reduced, and transport tasks of railways can be guaranteed to complete on time safely.
Description
Technical field
The invention belongs to the rail examination field, relate in particular to a kind of collecting method of taking into account on-the-spot flaw detection of rail and playback flaw detection demand.
Background technology
Generally use the hand propelled rail flaw detector that rail is detected a flaw on the railway now.Along with popularizing and use of digital rail flaw detector, utilize the omnidistance writing function of digital rail flaw detector, the data of the back collection of detecting a flaw are analyzed again found the hurt of on-the-spot flaw detection omission to become more and more important.
So in fact the scene is detected a flaw and born 2 tasks now, one is to detect a flaw in the scene, and another one is that image data is carried out the playback flaw detection so that return through data analysis.But 2 kinds of methods of detection here have different requirement to the setting of flaw detection sensitivity.
On-the-spot flaw detection owing to mainly be to rely on that listening reports to the police detects a flaw, hears that can adjust sensitivity after the warning proofreads to confirm hurt again.Because can improve sensitivity check and correction at any time, it does not need higher sensitivity when carrying out, and if sensitivity be provided with higher, the scalelike mark on the rail level, the clutter that falls generations such as piece also will produce on-the-spot flaw detection of a large amount of warnings influences.
The playback flaw detection is to analyze through the B ultrasonic data that collection is returned to detect a flaw.Owing to be to detect a flaw on computer screen through vision, and the clutter of generations such as scalelike mark and flaw echo are had any different, these clutters can not produce the playback flaw detection and disturb.But the playback flaw detection can not proofreaded through improving sensitivity at the scene, can only confirm to handle according to the data of gathering.So the remolding sensitivity that playback flaw detection hope flaw detection worker is provided with when image data is higher.
On-the-spot flaw detection needs lower sensitivity, and the playback flaw detection but needs higher sensitivity, and is conflicting between the two.Unallowed again twice detection, the image data respectively of carrying out of present manpower and materials.
Summary of the invention
To above deficiency, the sensitivity different demands is provided with following invention to this:
The technical scheme that adopts is: rail flaw detector with probe in a transmit cycle, launch radioactive wave twice, the reflection wave that reflects, the sensitivity of once using the flaw detection worker to be provided with receives, the result of reception is used for on-the-spot flaw detection, produces warning; Primary reflection uses higher sensitivity to receive in addition, and the result of reception is kept at omnidistance record the inside, and on-the-spot flaw detection worker can't see, and is visible when having only playback.
Characteristic of the present invention:
Rail flaw detector with probe in an emission cycle, launch radioactive wave twice.
2. the reflection wave that reflects of twice radioactive wave receives respectively, and it is different to receive the sensitivity of being adopted, and one high, and one low.
3. the data of all collections of muting sensitivity transmitted wave are used for on-the-spot flaw detection, produce and report to the police, and produce the ultra waveform of A, and on-the-spot flaw detection worker is based on its on-the-spot flaw detection and verification.
4. the data that received of high sensitivity reflection wave only are kept in the omnidistance record and go, and the B ultrasonic data recording of gained is in the whole process record, and when the playback of whole process record, playback person carries out the playback flaw detection according to the waveform that these two kinds of sensitivity produce to it.
5. during playback, playback person promptly can browse high sensitivity to the data of being gathered and receive the B ultrasonic data that produced, and also can browse the data that muting sensitivity produces.
The invention has the beneficial effects as follows: through defectoscope with probe in a transmit cycle, launch radioactive wave twice, the sensitivity that the reflection wave that reflects once uses the flaw detection worker to be provided with receives, the result of reception is used for on-the-spot flaw detection, produces and reports to the police; Once use higher sensitivity to receive in addition, the result of reception is kept at omnidistance record the inside, and on-the-spot flaw detection worker can't see, and is visible when having only playback.Two kinds of data have been gathered in once work through the flaw detection worker, have saved manpower and materials.Improved the defect detecting test ability simultaneously, effectively reduced the generation of rail accident, ensured railway security, accomplished transport task on schedule.
Embodiment
Further the present invention is explained according to embodiment below:
Embodiment: when the hand propelled rail flaw detector carries out rail examination; The hand propelled rail flaw detector with probe in a transmit cycle, launch radioactive wave twice; Radioactive wave is run into rail respectively and is produced the reflection wave that reflects; The sensitivity of once using on-the-spot flaw detection worker to be provided with receives, and the result of reception is used for on-the-spot flaw detection, produces and reports to the police; Primary reflection uses higher sensitivity to receive in addition, and the result of reception is kept at omnidistance record the inside, and on-the-spot flaw detection worker can't see, and is visible when having only playback.
