And (3) collaborative design: the collaborative design is an important direction for technology updating of the current design industry and is a necessary trend of design technology development, wherein two technical branches exist, namely the collaborative design is mainly suitable for large-scale public construction and three-dimensional BIM collaboration of complex structures, and is mainly suitable for two-dimensional CAD collaboration of common buildings and houses. The unified design standard including layers, colors, line types, printing styles and the like is established through collaborative design, on the basis, all design professionals and personnel design on a unified platform, so that mistakes, omissions, collisions and defects caused by unsmooth communication or untimely communication among the current professionals (and inside the professionals) are reduced, the unicity of all drawing information elements is really realized, other automatic modification is realized, and the design efficiency and the design quality are improved.

Example one
As shown in fig. 1, an embodiment of the present invention provides a cross-domain and allopatric collaborative design method in a mass data environment, where the method includes:
step 110: carrying out lightweight processing on the three-dimensional model to obtain a lightweight model; further, the performing a weight reduction process on the three-dimensional model to obtain a weight reduction model further includes: obtaining a first component part; determining whether the first component part has been lightened; judging whether all the component parts are read or not if the first component part is lightened; if all the constituent parts have been read, a lightweight model is obtained. If all the constituent parts are not read, the constituent parts are read one by one until all the constituent parts are read. If the first component part is not light-weighted, extracting design element information of the three-dimensional model, wherein the design element information comprises attribute information and marking information; generating an XML file for storing the design element information; and carrying out lightweight processing on the three-dimensional model to obtain a lightweight model.
Specifically, as shown in fig. 1, the three-dimensional design model product structure tree of the complex product is composed of region-system-component-part step by step, and after the three-dimensional design model is opened, the composed parts are read one by one. And searching whether the lightweight model of the part model is constructed or not from the lightweight cache. If not, important design element information such as attribute information, marking information and the like of the part model is read, the part model is stored as an XML format file by adopting a uniform structure, and the lightweight model is conveniently loaded to read the relevant design element information. Meanwhile, a method of replacing the outer surface of the model by triangular piece surface combination is adopted to carry out lightweight processing on the part model to generate a lightweight model, the data volume of the lightweight model is generally 8% -10% of that of the original three-dimensional model, and a designer can conveniently and rapidly load a design background model.
Step 120: constructing a cross-domain allopatric collaborative design network environment; further, the constructing a cross-domain allopatric collaborative design network environment further includes: obtaining a design domain of the cross-domain allopatric collaborative design network environment, wherein the design domain comprises a first design domain and a second design domain, and the first design domain is a main design domain; the first design domain comprises a first three-dimensional design server, a first three-dimensional design data warehouse, a first lightweight cache server and a first three-dimensional design workstation; the second design domain comprises a second three-dimensional design server, a second three-dimensional design data warehouse, a second lightweight cache server and a second three-dimensional design workstation; wherein the second design domain is synchronized with the data increments in the first design domain.
Specifically, in order to meet the requirements of design and construction of complex products, a collaborative design environment needs to be established among design units, construction units and other related units, and the requirements of long-distance and high-speed transmission, quick loading and collaborative design of mass design data are met. The design unit design domain is a main design domain, and a three-dimensional design server, a three-dimensional design data warehouse, a light-weight cache server and a three-dimensional design workstation are deployed in the main design domain. In the main design domain, designers directly access the three-dimensional design server and the main three-dimensional design data warehouse through a gigabit local area network, and the lightweight cache server stores the three-dimensional design model which is subjected to lightweight processing by adopting a three-dimensional model lightweight and design element extraction method, so that the loading speed of the three-dimensional model in the main design domain is further increased. And the design domain of other collaborative design units is provided with a three-dimensional design data warehouse, a lightweight cache server and a three-dimensional design workstation. And data in the three-dimensional design data warehouse and the lightweight cache server are in incremental synchronization with data in the main design domain three-dimensional design data warehouse and the main lightweight cache server in a timestamp comparison mode. An accelerator with a built-in protocol tuning algorithm is deployed between the collaborative design domain and the main design domain to improve the actual throughput rate of the internet special line bandwidth.
Step 130: completing loading of a three-dimensional design model in a cross-domain remote collaborative design environment; further, the completing the loading of the three-dimensional design model in the cross-domain allopatric collaborative design environment further includes: obtaining all parts to be loaded; obtaining a lightweight model corresponding to the part needing to be loaded; judging whether the quantization model exists or not; if the lightweight model exists, loading the lightweight model; and obtaining design element information in an XML file in the lightweight model, and completing the loading of the three-dimensional model. And if the lightweight model does not exist, loading the three-dimensional model from a three-dimensional design database of the current design domain to finish loading the three-dimensional model.
Specifically, a designer in the design domain accesses a three-dimensional design server in the main design domain to obtain a product structure tree, selects a region/system/component to be loaded, obtains all parts to be loaded from the three-dimensional design server, and searches a lightweight model corresponding to the parts to be loaded from a lightweight cache of the current design domain. If the required part model exists in the current design domain lightweight cache, the lightweight model is directly loaded, and designers can read the corresponding XML file through a developed tool to obtain the detailed design element information of the model. If the three-dimensional model does not exist, the three-dimensional model is loaded from the three-dimensional design data warehouse of the current design domain, and the time for loading the three-dimensional model is 4 to 5 times longer than that for loading the corresponding lightweight model, so that the completeness of the lightweight model in the lightweight cache needs to be ensured.
Step 140: and switching the loaded lightweight model to the three-dimensional design model to develop collaborative design. Further, the switching the loaded lightweight model to the three-dimensional design model to develop collaborative design further includes: obtaining a part to be designed; obtaining all parts of said component; and loading the three-dimensional model from a current design and three-dimensional related data warehouse to replace the corresponding part lightweight model, and developing the collaborative design.
Specifically, after a design domain user adopts a lightweight cache to rapidly open a three-dimensional model as a design background, a part needing to be designed is selected, all parts forming the part are read, the three-dimensional model is loaded from a current design domain three-dimensional design data warehouse to replace the corresponding part lightweight model, and therefore the model can be modified and designed. And storing the corresponding relation between the three-dimensional design model and the lightweight model in a three-dimensional design server of a main design domain by using structured data, reading the incidence relation information from the main design domain when a user selects to switch the lightweight model into the three-dimensional design model, and loading the three-dimensional design model from a three-dimensional design data warehouse of the current design domain. And designers use the loaded lightweight model as a design background and quickly switch the parts of the selected design parts into a three-dimensional design model, so that the cross-domain quick collaborative design work under the background of massive three-dimensional design data is realized.
The three-dimensional model lightweight and design element extraction method can greatly reduce the data volume of the three-dimensional design model, improve the loading rate of the background model during collaborative design, and quickly obtain the main design element information of the model under the condition that the lightweight model is not switched to the original three-dimensional model. The cross-domain remote collaborative design network environment in the mass data environment provides a distributed incremental backup three-dimensional design data warehouse and lightweight cache service, and greatly shortens the waiting time for remote collaborative designers to load a large-data-volume three-dimensional model. The method for switching the lightweight model and the design model facilitates the designer to switch the lightweight model into the original three-dimensional design model and quickly develop the collaborative design.
