In the process of ship manufacturing, if a craft worker encounters a problem and needs to acquire typical process data, the process demand data can be input into the process knowledge integration application platform, the process knowledge integration application platform acquires the typical process data closest to the process demand data, and the craft worker can issue a process to a constructor according to the typical process data.
And S102, selecting typical process data with the typical process type same as the required process type from the typical process library.
Specifically, the typical process data includes typical process types, typical process parameter items and typical process implementation data; the typical process data can be the construction data of the process with the best construction quality in the manufacturing process of the same batch of products, or the construction data of the high-quality process which is audited by an authoritative technologist. The typical process type is that of a typical process. The typical process parameter items are process parameter items of a typical process. The process implementation data may be values of specific parameters necessary to implement a typical process, and may illustratively be weld voltage, weld current, weld speed, and/or any other parameter data that may directly instruct the operator to implement the typical process.

Specifically, the preset threshold may be set by a user, and it may be determined whether the correlation degree between the typical process data and the required process data meets the requirement.

S303, if the required process parameter item is of a digital type, calculating a first correlation value of the required process parameter item according to a first formula; the first formula is that ki is 1- (| Ai-Bi |/Bi), where ki is a first correlation value of the ith required process parameter item, Ai is a numerical value of the ith typical process parameter item, Bi is a numerical value of the ith required process parameter item, i is a positive integer, and i corresponds to the required process parameter item one to one.
Specifically, the digital required process parameter item may be represented by a numerical value, and for example, the cutting thickness may be represented by 10 centimeters, and the cutting thickness is the digital required process parameter item, wherein the unit of the digital required process parameter item is consistent with the unit of the corresponding typical process parameter item. If a required process parameter item is digital, the typical process parameter item corresponding to the required process parameter item is also digital. A first correlation value of the required process parameter can then be obtained according to the first formula ki ═ 1- (| Ai-Bi |/Bi).
S304, if the required process parameter item is in a character type, judging whether the content of the required process data parameter item is completely consistent with that of the corresponding typical process parameter item, if so, determining that the first correlation value is 1, otherwise, determining that the first correlation value is 0.
Specifically, the character-type required process parameter item may not be directly represented by a number, but may be represented by a character, for example, the material of the cutting object may not be represented by a number, but may be represented by a Chinese character "wood", "metal", "composite board", or other words capable of representing the material of the cutting object, and the material of the cutting object is the character-type required process parameter item. When determining the first correlation value between the character-type demand process parameter item and the corresponding typical process parameter item, it is necessary to determine whether the content of the demand process parameter item is completely consistent with the content of the corresponding typical process parameter item, if so, the first correlation coefficient is 1, otherwise, the first correlation coefficient is 0.

S404, when the contents of the special parameter items are the same as those of the corresponding typical process parameter items, calculating a final correlation value according to the typical process parameter items and the required process parameter items.
Specifically, if the special parameter items of the required process data are different from the special parameter items of the typical process data, it indicates that the required process data and the typical process data have low correlation, and the typical process does not meet the requirements of the process workers and cannot guide the constructors to execute the required process, and at this time, the typical process data with different special parameter items need to be excluded and are not taken as the target process data. Furthermore, when the contents of the special parameter item and the corresponding typical process parameter item are the same, a final correlation value can be calculated according to the typical process parameter item and the required process parameter item: if the required process parameter item is a digital type, calculating a first correlation value of the required process parameter item according to a first formula, wherein the first formula is that ki is 1- (| Ai-Bi |/Bi), ki is the first correlation value of the ith required process parameter item, Ai is the numerical value of the ith typical process parameter item, Bi is the numerical value of the ith required process parameter item, i is a positive integer, and i corresponds to the required process parameter item one to one; if the required process parameter item is of a character type, judging whether the content of the required process data parameter item is completely consistent with that of the corresponding typical process parameter item, if so, the first correlation value is 1, otherwise, the first correlation value is 0; calculating a final correlation value based on the first correlation value and a second formulaAnd K is the final correlation value, and xi is a preset correlation coefficient of the ith parameter item.
S405, determining the typical process data with the final correlation value larger than a preset threshold value as target process data.
Step S405 is the same as step S204, and is not described herein again.
