Background

The existing ship product development has the characteristics of large quantity of batch construction, short construction period and high quality requirement, however, the traditional ship product assembly process mainly utilizes office software and a screenshot tool to compile process files and execution record tables, the word description is taken as a main part, the graph representation is taken as an auxiliary part, the design intention and the process requirement of the ship product assembly process files are expressed, the traditional process files are flat and static in information, field workers look up the process files and need to carefully browse a large number of associated drawings and standards, the process file description is often simple, the process file description needs to be digested and understood by combining self experience, and the execution efficiency is very low: in practice, workers have some autonomy, resulting in a high percentage of their experience and skill throughout the manufacturing ecology. And the traditional process file is difficult to dynamically adjust during execution, serial/parallel and condition judgment of the process are difficult to visually express, the production quality problem is caused by the aid of a large amount of temporary change and field scheduling management, the production period is influenced, process and execution are often disconnected, the situation of 'learning is not unified', a three-dimensional visual process workshop is urgently needed, information intercommunication and problem interaction among designers, operators and quality inspection personnel are realized, the traditional design problem processing flow is simplified, the working efficiency is improved, and the timeliness, traceability and uniqueness of file release are ensured.

Furthermore, after the ship assembly process passes through the DELMIA system simulation verification, the conventional method is to output verification information to relevant departments or production sites in modes of screenshot, screen recording and the like of the DELMIA system simulation process, and a three-dimensional process model containing information such as a product model, a resource model, an assembly flow, animation, a technical illustration, color, perspective transformation and the like in the DELMIA system cannot be directly inherited, if a three-dimensional operation guide book and the like need to be made, the three-dimensional process model needs to be made again in a 3Dvia Composer, a great deal of effort is spent, labor is repeated, and the three-dimensional model is difficult to extend to the production sites and customers from design and runs through the whole life cycle of the product.

Meanwhile, when the ship is built and delivered, various technical documents need to be filed and delivered, and due to the fact that tool software and data formats of process data at various stages are not uniform, an electronic version and a paper version coexist, management and tracing are difficult, and the ship is actually separated from engineering practice. The root of the problem lies in that the change of the process file cannot be timely and efficiently transferred to the completed technical document, the management of a data system is lacked, the delayed delivery of the ship product is possibly caused, and the consistent drawing and document cannot be accurately found in the post-maintenance process, so that the delivery quality of the ship product is influenced. And with the increase of the models of ship products, the maintenance cost of model catalogues, technical documents and the like is continuously increased.

and 4, step 4: browsing on site off line, perfecting an operation instruction book (204) according to feedback opinions, wherein an operator and a quality inspection worker browse the operation instruction book on site on line and off line and can feed back opinions; and the designer modifies the perfecting operation instruction book according to the feedback opinions.

7. The method according to claim 6, wherein the three-dimensional assembly work instruction design method comprises:

in the step 1, in the operation instruction book making module (111), a designer inherits a DELMIA design result through the design data inheriting and converting module (112) and calls design data and resource models required by the operation instruction book.

8. The method according to claim 6, wherein the three-dimensional assembly work instruction design method comprises:

step 2, obtaining design data and a resource model assembly body assembly relation by using an assembly structure adjusting module (113) to generate an assembly structure; according to the requirements, temporarily required process resources are inquired in a process resource basic database platform (101) through a resource data inquiry and reference module (114), relevant process information is inquired through a process information inquiry module (115), an assembly process sequence is planned through a process planning module (116), each assembly process or detection process of assembly is planned in a detailed process design module (117), each process and attention are displayed in detail through animation and diagrams, the correctness of the assembly sequence and the feasibility of man-machine operation are verified through an assembly simulation module (118), and otherwise, the process planning and the detailed process design are adjusted.

9. The method of claim 6, wherein the three-dimensional assembly work instruction sheet is:

and 3, after setting the use permission of the operation instruction according to the template customized in the operation instruction template customizing module (120) and using the operation instruction output module (121), outputting the operation instruction to a corresponding level under a structure tree defined by the process resource tree management module (107), configuring the user permission defined in the module (105) according to the user permission, selecting personnel meeting the proofreading, auditing and approving permission in the proofreading and approving flow module (122), submitting the approval and approval flow, feeding back the comments and refuting the flow by the proofreading, auditing and approving personnel in the flow, re-initiating the approval and approving flow after modifying the operation instruction according to the comments by the designer, and issuing the operation instruction to field operators and quality control personnel until the proofreading, auditing and approving pass and embedding a corresponding electronic signature in the operation instruction.

10. The method of claim 6, wherein the three-dimensional assembly work instruction sheet is:

in the step 4, an operator and a quality inspector can export the issued operation instruction to the tablet personal system according to the user authority by using a data exchange interface between the process resource basic database platform (101) and the tablet personal system in the operation instruction export module (124) for offline browsing or rapid filing; browsing the published work instruction on-line with an on-line off-line browsing module (125) or browsing the derived work instruction off-line in the tablet system; the operation instruction book is added with marks and comments by using the circulation reading opinion feedback module (126), the opinions are fed back, and after the designer receives the feedback opinion, the operation instruction book is modified and perfected based on the operation instruction book making module (111), and the operation instruction book with a new version is released to the operator and the quality inspector again.
