Problems solved by technology

[0003] In the prior art, the invention patent "A Portable Flaw Detection System and Its Detection Method for Train Wheels" discloses a portable flaw detection system and its detection method. Its hardware structure is as follows: figure 1 As shown, it can be seen from the figure that the portable flaw detection system does not integrate power supply, water tank, client, etc., which makes the system need an external power supply, water tank, etc. in actual operation, and there is a certain inconvenience in operation. In its claims , it is clearly stated that the moving speed of the train is less than or equal to 5km / h, and 3.6km / h is the optimal speed. This speed cannot meet the requirements of the locomotive depot for flaw detection efficiency. , B-scan, but no C-scan and 3D display, and no cloud data transmission function
The invention patent application "A Follow-up Ultrasonic Flaw Detector for Locomotives" discloses a follow-up ultrasonic flaw detector for locomotives. This invention is similar to a mechanical arm, with cumbersome installation, complex internal control logic, high cost, and high detection efficiency. There are some deficiencies in the way of displaying defects

Embodiment 1

[0043] The train wheel follow-up intelligent flaw detection system of this embodiment, such as figure 2 Shown; including data acquisition modules, such as image 3 Shown; communication module, such as Figure 4 Shown; integrated control module and cloud data transmission module, such as Figure 5 Shown. Data acquisition module ( image 3 ), one or more sets of data acquisition modules work simultaneously to detect different wheels of the same train; including brackets ( figure 2 (1)) Install the ultrasonic excitation board directly above the bracket ( image 3 (3)) The power supply 4, the water tank 2, the probe 7, the encoder 6, the water pipe, and the nozzle 8 are installed on one side of the bracket. The ultrasonic excitation board connects the probe, the encoder and the motor; the power supply supplies power to the ultrasonic excitation board, the motor, and the client; the client 5 is installed above the bracket and connected to the ultrasonic excitation board; the water t...

Embodiment 2

[0045] The wireless client of the communication module and the data acquisition module are integrated, high-power routing ( Figure 4 ) Is placed inside the control cabinet, integrated with the comprehensive control module and the cloud transmission module, the structure diagram is as follows Figure 5 , The distance between the client and the wireless router is less than or equal to 50m, and the gain antenna is greater than or equal to 2dB. The operating steps of the software system are as follows: firstly, verify that the user name and password are correct, and enter the flaw detection system according to user authority; secondly, enter the detection information; again, send the start acquisition command to start real-time flaw detection; finally, replay the real-time detection results, And produce reports, and start cloud data transmission at the same time, the detailed workflow is as Image 6 Shown. The real-time flaw detection interface of the software is like Figure 7 As ...

Embodiment 3

[0047] Cloud data transmission module, including server, network card, storage cloud. When the software system issues a cloud storage command, the software first converts the data into the format required for cloud transmission and temporarily stores it on the industrial computer, then starts the server calling program, the server calling program continuously reads the data, and transfers the data through the 3G / 4G network card The data is sent to the cloud. The cloud has a large storage space and multiple interfaces. Each interface has a unique address. The upload and download of different types of data can be realized through the cloud interface, so as to realize the backtracking of the original data and the alarm data. shared. The workflow of the cloud data transmission module is as follows Picture 9 Shown.

Description

Technical field [0001] The invention relates to the field of non-destructive testing, and more specifically, to an ultrasonic testing system and method for internal defects of train wheels in rail transit. Background technique [0002] At present, the speed-up and heavy-duty development of railway transportation has resulted in increased wheel abrasion, peeling, out-of-roundness, and abnormal wear. Especially serious rim circumferential cracks have occurred from time to time, which directly endangers driving safety. Therefore, non-destructive testing of locomotive wheels and judging the type and location of damage inside the wheels have always been a matter of great concern to the railway transportation department. Therefore, the development of a train wheel follow-up intelligent flaw detection system is very useful for ensuring the daily safety of trains. necessary. [0003] In the prior art, the invention patent "A portable flaw detection system for train wheels and its detectio...
