Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The equipment manufacturing industry is a general name of various manufacturing industries for simply producing and expanding and reproducing equipment for each economic department, is a core part of industry, bears the important role of providing a working machine for each national economic department and driving related industries to develop, can be said to be an industrial heart and life line of national economy, and is an important basic stone for supporting the comprehensive national force of China.
In the production process, the material is produced, stored and assembled, and the material obtained in each stage must be ensured to be uniform in all three stages.
If manual management is used, negligence is likely to occur, so that the finally obtained materials are not nested, and the existing management system cannot grasp the increasing and decreasing relation at the stage for balance analysis.
For this reason, the invention provides a material management system for equipment manufacturing enterprises, as shown in fig. 1, the management system at least comprises a modeling area 100, a comparison area 200 and an alarm module 300, the modeling area 100 respectively builds models corresponding to three stages of production, inventory and assembly to obtain a production model, an inventory model and an assembly model, a material increasing relationship exists between the production model and the inventory model, specifically, an increase in the number of models in the production model leads to an increase in the number of models stored in the inventory model, and the reason for the increasing relationship is that: the materials produced by the manufacturing enterprises are put in storage, so that the quantity of the put materials is increased by one every time each material is produced; the reduction relationship between the assembly model and the stock model, particularly, the increase of the model number in the assembly model leads to the reduction of the storage model number in the stock model, so that the reduction relationship is generated because each assembly of one material needs to be taken out of the stock, and the material number in the stock is reduced by one.
The above-described increasing relationship or decreasing relationship is not only an increase or decrease in the number, but also an increase or decrease in the specific material.
Then, the comparison area 200 performs comparison analysis on the models with the relationships based on the increasing and decreasing relationships of the materials, and the alarm module 300 alarms on the analysis results with the anomalies in the comparison analysis process, so as to remind the staff to check the conditions of each stage, thereby ensuring the integrity of the materials of each stage.
The analysis principle is as follows:
firstly, the modeling area 100 includes a production model construction module 110, an inventory model construction module 120 and an assembly model construction module 130, the production model construction module 110 constructs a production model according to the produced materials, and at this time, the production model detects whether the produced materials are required by the component model, and because the production model is a model of a certain equipment or a production line and forms a material model corresponding to the model, whether the produced materials are aligned can be determined by comparing the produced material model with the production model;
meanwhile, the inventory model construction module 120 constructs an inventory model according to the materials in the warehouse, the inventory model is a process of inventory increment, and the inventory model is mainly used for checking whether the storage position of the materials in the warehouse is correct or not, because once the production model is built, the materials in the warehouse are indicated to be in alignment, but the situation of missing materials in the warehouse is not excluded, and once the missing materials or the storage position is incorrect, the inventory model cannot be built, so that the materials in the warehouse are ensured to be in alignment;
next, the assembly model construction module 130 constructs an assembly model according to the assembled materials to assist in the assembly of the materials, and particularly in the case of many similar small parts, the assembly model assists in the accuracy of the material falling during the assembly, and at the same time, the assembly model construction module can check the materials, and can quickly confirm what type of materials are fewer even if the materials lack the assembly model.
Further disclosure is made of a comparison manner of models with increasing/decreasing relationships, and with continued reference to fig. 1, the comparison area 200 includes an upstream comparison module 210 and a downstream comparison module 220, where an input end of the upstream comparison module 210 is configured to receive a production model and an inventory model, and after the increasing relationships are generated, compare and analyze a balance relationship between the production model and the inventory model, that is: the material model generated in the production model needs to have a built feedback of the stock model, the feedback is generated by successfully warehousing the material, the building in the stock model is completed, the relationship is a balance relationship, if the warehousing is not carried out due to missing materials or the warehousing position is incorrect, the missing part of the production model is not corresponding to the part needing to be added in the stock model, and then the abnormality can be found through comparative analysis (after the relationship is generated, the balance between the production model and the stock model is not maintained);
in addition, the input end of the downstream comparison module 220 is configured to receive the inventory model and the assembly model, and compare and analyze the balance relationship between the inventory model and the assembly model after the subtraction relationship is generated, namely: the reduced material model in the stock model requires that the assembly model has a built feedback that is generated from the reduced material model in the stock model with a precise placement in the corresponding assembly position, i.e., the build of the corresponding material model in the assembly model, and the reduced relationship is a balance relationship during the assembly process, whether the material is lost or the assembled material is not precisely placed, which results in the balance relationship being destroyed (after the reduced relationship is generated, the balance between the stock model and the assembly model is not maintained).
The output ends of the upstream comparison module 210 and the downstream comparison module 220 are connected with the alarm module 300, and any relationship of the increasing and decreasing relationships can alarm without maintaining balance.
It should be noted that, the downstream comparison module 220 operates on the following preconditions: the production model and the stock model are balanced after the increase relation is generated, and the materials in the stock are guaranteed to be in a uniform set.

the materials assembled to the appointed assembly position are taken out by means of the stock model, and the taken out material blocks are automatically filled into the empty positions of the corresponding material blocks in the assembly empty model, so that the assembly model is built by the material blocks.
It should be noted that the material block obtaining method includes selecting and parameterizing modeling in a material model library, where:
the parameterized modeling is completed by using an Autodesk Revit, and the Revit interface is utilized to extend the functions of the software.
In addition, a reusable material model library is constructed while parameterized modeling is performed, so that the workload of later parameterized modeling is reduced, and the material model library is directly used for selection.
Specifically, the production empty model and the assembly empty model form an empty model system together, and the empty model system adopts a filling method of multi-node matching, and the steps are as follows:
