The IETM is a product of development of modern electronic information technology, and is used for digitizing paper technical materials to form an electronic document, and simultaneously, various information elements are stored in a database as basic information units, and information data related to each other are stored according to a certain structure. The storage is independent of a particular configuration in accordance with the neutral pattern of the relevant skill criteria. When the user uses the information data, the information data can be embodied in various ways such as words, forms, pictures, drawings, sound, videos and animations, the user can interact with a computer, the information data are mutually referred, the information required by various inquiry and navigation function inquiry is provided, and the display style conforms to a common standard. The existing IETM function mainly queries related technical data, the format of stored information data mainly comprises characters, tables, pictures, drawings, sound, videos and animations, the interaction mode mainly comprises mouse clicking and touching, maintenance and guarantee training in a mode close to natural and real interaction is difficult to achieve, and technical information required by the using and maintenance processes of equipment is difficult to be normalized and classified digitally.
Therefore, in order to solve the above-mentioned problem, in the embodiment of the present application, first, basic element information related to weapon equipment is acquired based on multiple channels. As shown in fig. 2, the basic element information may be an audio/video element, a plug-in element, an interactive element, a text element, a drawing/drawing element, a table element, etc. acquired based on various channel summaries, and the basic element information is stored in a basic information layer of a preset object-oriented hierarchical database as shown in fig. 2. After the basic element information related to the weapon equipment is obtained, in order to abstract and generalize the basic element information to form technical information content, the design of a content data model based on elements is convenient.
And then in order to effectively increase the interactive mode of the IETM, simultaneously facilitate multiplexing and searching of the IETM content information and reduce the dispersion of maintenance guarantee data information, firstly, the required technical information content needs to be normalized and digitally classified, namely, the technical information content is written into a data packet, and is divided into corresponding element information according to the use type corresponding to the technical information content in the data packet. The method is convenient for constructing each sub-model in the IETM content data model through the combination and integration of element information, and effectively increases the interaction mode of the IETM through the organic integration of the element information. And then, on the basis of the organic integrated element information, the corresponding IETM output module is formed through element information mapping in each sub-model, so that the functions of auxiliary maintenance, auxiliary exercise and the like are realized in a real and natural interaction mode, meanwhile, the auxiliary equipment design can be reversed, and the problem that in the existing mode, the IETM is manufactured after the equipment is produced and shaped, and multiple supports are difficult to be provided for the later IETM is solved. Meanwhile, the multi-output module for obtaining the IETM data model based on multi-element organic integration solves the problem that IETM related means are single in the prior art. And based on the construction of the IETM content data model, the digitization of the content data model is realized, and the problems of a large number of paper documents, high storage difficulty, high maintenance cost, slow information transmission and the like are solved.
In one embodiment, as shown in fig. 2, the basic element information is processed at a function control layer of the hierarchical database to obtain technical information content corresponding to the basic element information, which specifically includes the following steps:
firstly, dividing basic element information acquired based on multiple channels on a function control layer of a hierarchical database based on information content to acquire step information and process information; wherein, the basic element information known by the steps comprises: text, forms, drawings, audio, plug-ins, interactive information, etc. And then acquiring different steps in the step information to acquire key steps in the different steps and key processes corresponding to the key steps based on constraint conditions and assignment data of the different steps. The constraint conditions of the different steps include a pre-constraint condition and a post-constraint condition, wherein the pre-constraint condition is a condition before the current step is executed, the post-constraint condition is an influence after the current step is executed, and the assignment data is information of the current step and is used for describing the current operation. After determining the key steps in different steps according to the constraint conditions and the assignment data, determining the task information corresponding to the step information according to the key steps and the key process, thereby realizing comprehensive description of the task information. Wherein, it should be noted that the steps include: sequential steps, selection steps, and circulation steps. And then, different processes in the process information are acquired, so that description information corresponding to the process information is determined based on constraint conditions and assignment data of the different processes. Wherein, it should be noted that the different processes include: sequential process, selection process, cyclic process. The process of further abstracting and generalizing the basic information and the technical information to form the descriptive information and the task information is realized based on the above process. At this time, the task information and the description information are used as the technical information content corresponding to the basic element information, so that the technical information content is written into the data packet. In addition, the data packet is a corresponding data structure determined by the relationship of each technical information content. For example: if the information is in parallel relationship, the data packet is set, and if the information is in membership relationship, the data packet is class, i.e. the data packet can be one of the data structures of the structure, class, set, etc.
In one embodiment, the element-based IETM content data model describes the data description of the components and their connections in the equipment system as a monolithic logical structure of relationships between complex data. The implementation of the organic integration of the information elements in the process of constructing the overall logic structure is an important link, and the element application layer in fig. 2 is required to divide the usage type corresponding to the technical information content in the data packet, that is, the use of the element content, into corresponding element information according to the usage type corresponding to the technical information content, so as to manage the elements of the same type, that is, when inputting information, the attributes of the elements are created according to the technical information content, and then the data structure of each type of element is created according to the element attributes. In the embodiment of the present disclosure, according to the usage type corresponding to the technical information content in the data packet, the usage type is divided into corresponding element information, which specifically includes the following steps: firstly, the use type and the association relation of each technical information content in a data packet are obtained.

And then determining the type of the element of the data packet according to the use type corresponding to the technical information content. The types of the elements include: general elements, operation elements, maintenance elements, and guarantee resource elements. And then determining the data structure of the data packet according to the association relation of the technical information content, so as to construct corresponding element information based on the data structure and the element type. For example: the information is in parallel relation, then the data packet is set, and if the information is in membership relation, the data packet is class, namely the data packet can be one of data structures such as a structural body, class and set. The construction of the element information is achieved by writing the technical information content into the data structure of the element type, i.e. the data package is divided into element information.
Specifically, in a certain application scenario in the present specification, firstly, the technical information content in the data packet is acquired, and if the usage type corresponding to the technical information content is determined, the usage type corresponds to a part of the weapon equipment, for example: the attribute of the technical content information comprises information such as part names, codes, versions, technical requirements, technical specifications, standards, functional descriptions and the like, then the element type of the data packet is a general element, at the moment, the data structure of the general element is determined based on the association relation attribute of the technical information content in the data packet, and then the technical information content in the data packet is assigned to the data structure of the general element. If the usage type corresponding to the technical information content is determined, the man-machine interaction process corresponding to the weapon equipment, such as the attribute of the technical information content includes interaction information such as geometric model, interaction action, operation sequence, tool transformation, assembly sequence, part moving path and the like, the element type of the data packet is an operation element, at this time, the data structure of the operation element is determined based on the association relationship attribute of the technical information content in the data packet, and the technical information content is assigned to the data structure of the operation element. If the usage type corresponding to the technical information content is determined, the maintenance guarantee corresponding to the weapon equipment, such as the attribute of the technical information content, comprises a fault part name, a fault mode, a cause, a phenomenon, an influence, a fault level, a fault frequency, a maintenance guarantee scheme and the like required by the maintenance guarantee, the element type of the data packet is a maintenance element, at the moment, the data structure of the maintenance element is determined based on the association relation attribute of the technical information content in the data packet, and the technical information content is assigned to the data structure of the maintenance element. If the usage type corresponding to the technical information content is determined, the maintenance resource corresponding to the weapon equipment, such as the attribute of the technical information content, comprises information of maintenance facilities, maintenance tools, spare parts, requirements of maintenance personnel and the like, the element type of the data packet is a guarantee resource element, at the moment, the data structure of the guarantee resource element is determined based on the association relationship attribute of the technical information content in the data packet, and the technical information content is assigned to the data structure of the guarantee resource element.
In one embodiment of the present disclosure, the general elements mainly refer to basic information of the parts, including information such as names, codes, versions, technical requirements, technical specifications, standards, and functional descriptions. The operation elements mainly refer to man-machine interaction information, and the man-machine interaction information comprises all interaction information such as a geometric model, interaction actions, operation sequences, tool transformation, assembly sequences, part moving paths and the like.
