[0051] Embodiment 2

[0052] This embodiment is further optimized on the basis of the above-mentioned embodiment 1. In this embodiment, the method for constructing the aircraft component assembly connection process parameter library comprises:

[0053] According to the data retrieval scheme, data source and logical rules of the process parameters used in the aircraft component assembly process, the data form of multi-dimensional input / output of the aircraft component assembly connection process parameter library is constructed;

[0054] According to the assembly connection process experience and assembly connection process requirements of the aircraft component assembly connection process, the assembly connection process knowledge and assembly connection process rules are generated;

[0055] According to the key fields in the aircraft component assembly connection process parameter library, the data tables in the aircraft component assembly connection process parameter library are associated, and the data association relationship between the aircraft component assembly connection process parameter libraries is constructed;

[0056] According to the data association relationship, the data form, the assembly connection process knowledge and the assembly connection process rule, the aircraft component assembly connection process parameter library including the aircraft component assembly connection process parameter library and the aircraft component assembly connection general process parameter library is established;

[0057] A parameter acquisition mode of unified pushing data is constructed for the aircraft component assembly connection process parameter library, and a parameter acquisition mode of active data retrieval is constructed for the assembly connection general process parameter library.

[0058] Specifically, according to the data retrieval scheme, data source and logical rule of the process parameters used in the component assembly process, the multi-dimensional input / output data form of the aircraft component assembly connection process parameter library is constructed, CLASS1{IN1; OUT1}, CLASS2{IN1, IN2, ……INn; OUT1}, CLASS3{IN1; OUT1, OUT2, OUT3, ……OUTn}, CLASS4{IN1, IN2, IN3, ……INn; OUT1, OUT2, OUT3, ……OUTn}; wherein CLASS1 represents the program unified identification supporting initial data; CLASS2 represents that after supporting multi-condition input, the logic infers a unique result; CLASS3 represents that after supporting data input, the multi-dimensional definition outputs different dimensional results which can be applied in different scenes; CLASS4 represents that after supporting multi-condition input, the logic infers different dimensional results which can be applied in different scenes.

[0059] According to the process experience and process requirements of the aircraft component assembly connection process, induction and reasoning are performed to form process knowledge and process rules. In order to reduce data redundancy and increase the coherence between data, 9 aircraft component assembly connection process parameter libraries are constructed, including 6 aircraft component assembly connection process parameter libraries and 3 aircraft component assembly connection general process parameter libraries.

[0069] Unified push data parameter acquisition mode:

[0070] To avoid repeated retrieval of process parameters during process procedure compilation, a set of parameter libraries and matching logic rules are uniformly established. According to the aircraft part assembly connection process procedure template and the corresponding process, the process parameter library uniformly pushes the general process parameter information to the process, and puts it into the corresponding parameter position of the process;

[0071] Standard operation procedure library {input: aircraft part assembly connection process procedure template name, process name, drawing number feature…; output: standard operation procedure number, standard operation procedure name};

[0072] Certificate information library {input: aircraft part assembly connection process procedure template name, process name, drawing number feature…; output: certificate code};

[0125] Further, each procedure corresponds to a unique procedure label to distinguish procedures with the same name.

[0126] Specifically, in this multi-level structure, each assembly scene corresponds to a plurality of aircraft part assembly connection process procedure templates, each aircraft part assembly connection process procedure template contains a plurality of procedure sets, and each procedure set can contain a plurality of procedures with the same name. In order to solve the identification problem of the procedures with the same name, this embodiment introduces the concept of "procedure label", which realizes accurate differentiation between procedures with the same name by assigning a unique label to each procedure.

[0127] Further, the method for distinguishing procedures with the same name includes:

[0128] Firstly, according to the current assembly scene, a target aircraft part assembly connection process procedure template matching the current assembly task is selected, then according to the target aircraft part assembly connection process procedure template, a target procedure set matching the current assembly task is selected and a preliminary positioning is performed in the target procedure set according to the name of the target procedure; finally, through the procedure label corresponding to the target procedure, the target procedure is positioned in the procedure with the same name as the target procedure.

[0129] In an optional embodiment, the method for distinguishing the procedures with the same name comprises the following steps:

[0130] The assembly scene is determined, specifically, the current assembly scene is first determined, which is the starting point of finding the procedure;

[0131] The aircraft part assembly connection process procedure template is selected, specifically, in the assembly scene, the aircraft part assembly connection process procedure template matching the current assembly task is selected;

[0132] The procedure set is positioned, specifically, in the selected aircraft part assembly connection process procedure template, the procedure set related to the assembly task is found;

[0133] The procedure name is identified, specifically, in the procedure set, the preliminary positioning is performed according to the name of the procedure;

[0134] The procedure label is applied, specifically, finally, through the unique procedure label, the target procedure is accurately identified from the possible procedures with the same name.

[0135] Further, the method for determining the structure form of the procedure set comprises:

[0136] The procedure with more than one trigger condition is divided into multiple procedure sets corresponding to the trigger conditions, and the procedure that will be triggered in the specified assembly scene is divided into an independent procedure set.

[0137] Specifically, the concept of the procedure set plays a core role in the design of the aircraft assembly aircraft part assembly connection process procedure template, which is composed of one or more procedures, and these procedures have a common trigger condition. Each procedure in the procedure set will be activated at the same time when encountering a specific material feature or process scheme. This mechanism ensures that related procedures can be automatically and synchronously executed in the assembly scene that meets the specific conditions, improving the efficiency and consistency of the assembly process.

[0138] For those procedures with extremely strong universality and which need to be executed under multiple conditions, the embodiment divides them into multiple procedure sets at the same time, which can ensure that these key procedures can be triggered in any assembly scene, avoiding process defects that may be caused by condition judgment omission;

[0139] In addition, for the process that needs to appear in the designated assembly scene and is not affected by any condition, the embodiment sets a default process set that appears, which ensures that the processes can be automatically executed in any case and can flexibly meet the needs of different assembly scenes, ensuring accurate triggering and efficient execution of the processes.
