Step 3：Detection connection button is clicked on, whether detection industrial personal computer is connected with equipment, after successful connection, selects this
The wheel to be detected clicks on drop-down list selection license number and axis sequence, into real-time flaw detection interface.
Step 4：Host computer is sent to control unit starts acquisition and boiling water pump order, and defect-detecting equipment proceeds by spy
It surveys.
Step 5：Wheel rotates after two weeks, and water pump is automatically stopped, and host computer, which is sent, stops acquisition.It is sent out successively to equipment
Loading command is sent, makes equipment that data be passed to host computer one by one, and shows that A is swept, B is swept, C sweeps figure simultaneously.
Step 6：In data upload process, the problem of if there is frame losing or crash, loading command is resend i.e.
Data can be uploaded again.
Step 7：Data readback is locally being carried out, can check that B is swept, C is swept, D sweeps figure and the position of defect and depth information,
Situation the defects of under different gate values is shown by regulator gate value, PDF format report can be generated under different gate values,
Long-range checked checked using Web, can check that B is swept, C sweeps figure and the position of defect and depth information.
Step 8：Flaw detection terminates, and logs off, and clears up and is placed back in industrial personal computer after equipment is removed.
Wireless transmission effective distance between industrial personal computer unit and defect-detecting equipment is 100m.Every time after flaw detection, system
A file named with the time will be established under industrial personal computer (Fig. 5) corresponding folder, B is swept, C sweeps figure and the position of defect
It puts and is stored in depth information under file, when remotely being checked using Web, B can be swept, C sweeps figure and the position of defect
It puts with depth information remote exhibition on Web.
Defect is positioned according to the relative position of position coder 1, is taken a round position coder row according to wheel row
The distance walked calculates the perimeter of wheel, and defect is positioned further according to the present position of fault location position coder, comes
Draw that B is swept, C sweeps figure and the position of display defect and depth information.For prevent position coder 1 and wheel occur it is opposite slide and
Idle running, influences detection accuracy, and there are one springs 2 to give one inside pulling force of encoder always.
Embodiment 2：As shown in Fig. 2, defect is positioned according to the relative position of position coder 1, according to wheel row
The distance of the position coder that takes a round walking calculates the perimeter of wheel, comes further according to the present position of fault location position coder
Defect is positioned, is swept drawing B, C sweeps figure and the position of display defect and depth information.For prevent position coder 1 with
Opposite slip or idle running occur for wheel, influence detection accuracy, and there are one springs 2 to give one inside pulling force of encoder always.
Embodiment 3：The data received represent the depth information of wheel 1mm, are changed according to depth to be measured
The data amount check to be intercepted from a frame data the defects of such as measuring at 2-55mm, then intercepts the 2- after removing frame head
55 data.It data is dynamically plotted to B sweeps C and sweep in figure, you can the defects of observing institute's detecting location.
In conclusion a kind of new type train wheel trailing type smart flaw detection system detectio is efficient, graphical display effect is good
It is good, and the level of informatization is high, can realize train wheel information integral management, can facilitate and realize that long-range Web page is checked,
Be conducive to the shared and analysis of data.Above embodiment is merely illustrative of the invention's technical idea, it is impossible to limit this hair with this
Bright protection domain, every according to technological thought proposed by the present invention, any change done on the basis of technical solution falls
Enter within the scope of the present invention.Technology of the present invention can be subject to reality if unspecified by existing technology
It is existing.
