Detailed Description
It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
The main solutions of the embodiments of the present application are: the system comprises a two-dimensional code tag arranged on a thermocouple, wherein the two-dimensional code of the two-dimensional code tag comprises serial number information of the thermocouple corresponding to the two-dimensional code tag, one end of the thermocouple is arranged on an autoclave pipeline, and the other end of the thermocouple is embedded into a composite material for preparing a target part; the image acquisition unit is used for acquiring a target image of the laying position of the thermocouple and the autoclave pipeline, and the target image comprises the two-dimensional code; the image processing unit is used for processing the target image to obtain the corresponding relation between the thermocouple and the autoclave pipeline and the serial number information of the thermocouple; the first data association unit is used for establishing a first corresponding relation between the two-dimensional code tag and the autoclave pipeline according to the corresponding relation between the thermocouple and the autoclave pipeline and the serial number information of the thermocouple; and the second data association unit is used for establishing a second corresponding relation between the two-dimensional code label and the target part based on the corresponding relation between the thermocouple and the target part.
The autoclave is a key device in the curing and forming process of the composite material, the composite material blank is heated and pressurized by utilizing the high temperature in the autoclave and the pressure generated by compressed gas to finish the curing and forming, and a plurality of thermocouple pipelines are arranged on the tank walls of the autoclaves of different types. The whole curing and forming process of the part is that one end of a limited thermocouple is placed on the surface of the part in a closed autoclave, the other end with a plug is inserted into a pipeline on the wall of the autoclave, and the temperature information transmitted by the thermocouple pipeline is used for representing the surface temperature of the part. After the part is solidified and formed, a checker compares the temperature value, the vacuum degree and the technological parameters according to the relevant standards of the technological file to detect whether the quality of the part solidification meets the technological requirements. According to the actual production plan, the number of parts solidified by entering the tank each time has randomness, and the number of thermocouples placed on the surfaces of the parts is smaller than the number of pipelines. Thus, the tubing used to insert the thermocouple onto the autoclave can wall is random.
At present, the related information between the part and the thermocouple pipeline is still recorded in a simple and rough sketch form on the back of the autoclave paper operation record book by manual operation. Because the pipeline and the number of the thermocouple plugs which are manually inserted into the tank wall of the autoclave are random, and the thermocouple plugs and the pipeline are not in one-to-one correspondence. Thus, this approach is one aspect: recording errors due to human errors, and if the errors are recorded, misjudging the result of the curing quality of the part; on the other hand: the recording mode is more traditional, electronic version record data is not formed, and the inquiry and the reuse are inconvenient.
Therefore, the application provides a solution, wherein the two-dimensional code is arranged on the thermocouple, and the part label is related through the two-dimensional code; on the basis, recognition of the plugging association conditions of thermocouples corresponding to different parts and a plurality of pipelines is realized through image acquisition and image processing, namely, the system is based on the technical problem that the accuracy of manually carrying out data association work is low due to the randomness of the plugging of the thermocouples and the pipelines. Meanwhile, the operation efficiency of data association is remarkably improved.
Referring to FIG. 1, an embodiment of the present application provides a system for correlating part manufacturing process data, comprising:

the image acquisition unit is used for acquiring a target image of the laying position of the thermocouple and the autoclave pipeline, and the target image comprises the two-dimensional code;
the image processing unit is used for processing the target image to obtain the corresponding relation between the thermocouple and the autoclave pipeline and the serial number information of the thermocouple;

It should be noted that, in the scenario of the system of the embodiment, the number of parts solidified by entering the tank each time has randomness and the number of thermocouples placed on the surface of the parts is smaller than the number of autoclave pipelines in practical production according to the situations of a plurality of thermocouples and a plurality of autoclave pipelines. The target part refers to a part cured in an autoclave, and in this embodiment, may refer to a composite material before curing. Therefore, in order to identify the correspondence between the parts, the thermocouple, and the pipeline, it is necessary to provide a two-dimensional code tag on the thermocouple and perform visual identification.

And the second data association unit is used for establishing a second corresponding relation between the two-dimensional code label and the target part based on the corresponding relation between the thermocouple and the target part. Specifically, the second data association unit may be a code scanning gun, and when the composite material is buried in the thermocouple, the code scanning gun is used to associate the part bar code with the number in the thermocouple device, and the association result is stored in the database table 1.
The image acquisition unit is used for acquiring a target image of the laying position of the thermocouple and the autoclave pipeline, and the target image comprises the two-dimensional code.

Specifically, the distance between the central pixel coordinate of the grid and the pixel coordinate of the two-dimensional code can reflect the distance between the thermocouple and the pipeline, and the nearest distance can represent the plugging corresponding relation between the thermocouple and the pipeline. Therefore, if the minimum value of the distance is calculated from the third array, the correspondence between the thermocouple and the pipe can be identified.

wherein, Is an incident light function, represents light intensity components which are different along with the space position, and is concentrated in the low-frequency part of the image; is the reflection coefficient representing the reflection component of the scene to the human eye, and is concentrated in the high frequency part of the image.
Homomorphic filtering processing is carried out on the corrected image sequence, so that a filtered image sequence MT "= { T 1",T2",T3"...Tm-1",Tm" };
