In the computer and display, flaw detection data Acquisition Processor, ultrasonic wave or so visit wheel, CCD or so rail industrial camera, CCD
Data collection processor and synchronization encoders are detachable respectively is set on the trolley wheel platform.
3. a kind of double rail type steel rail ultrasonic flaw detecting according to claim 1 and picture control integrated system, feature exist
In the synchronization encoders use clamped-in style synchronization encoders.
4. a kind of double rail type steel rail ultrasonic flaw detecting according to claim 1 and picture control integrated system, feature exist
In the synchronization encoders use multi output synchronous signal encoder.
5. a kind of double rail type steel rail ultrasonic flaw detecting and image monitoring method, which comprises the following steps:
Step 1: starting double rail type steel rail ultrasonic flaw detecting and frequency image monitoring system start to detect；
Step 2: synchronization encoders are advanced with trolley wheel platform from triggering clock cycle signal, and are sent to spy simultaneously
Hurt data collection processor and ccd data Acquisition Processor, work at the same time it, is exported using same decoders-Synchronous to flaw detection
Instrument flaw detection signal triggering and the shooting signal triggering of CCD line-scan digital camera, make flaw detection data and image data have unified position always
Information record；
Step 3: flaw detection data Acquisition Processor and ccd data Acquisition Processor are with the work of regular hour frequency, flaw detection data
Acquisition Processor and ccd data Acquisition Processor are simultaneously by the synchronous number preservation of the data of work, and immediately by the number of preservation
According to computer is uploaded to, further comprising: flaw detection data Acquisition Processor will carry out collected ultrasonic examination data
Encoder position calibration, ccd data Acquisition Processor will carry out encoder position calibration, instantly to the Rail Surface image of shooting
When one group of synchronization encoders pulse signal cycle instruction reaches, flaw detection data Acquisition Processor and ccd data Acquisition Processor are
When transmit data on computer and display；
Step 4: computer handles flaw detection data Acquisition Processor and ccd data Acquisition Processor while the warp sended over immediately
The synchronization signal for crossing synchronization encoders number will handle its data, be analyzed, in final simultaneous display rail over the display
Ultrasonic examination situation and Rail Surface image；
Step 5: playback software will be same according to the ultrasonic examination data and ccd image data of passing through synchronization encoders numbering
One time called out, for the rail internal ultrasonic wave inspection situation and rail of unified location information record to be played simultaneously
Surface image.
