Detailed Description
The invention is further described below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
As shown in fig. 1, an MES-based production management system includes: the main storage unit is used for completely storing production execution data, in the process of enterprise management, the complete storage of the production data is very important for the later retrospection of products, the original production process of the products can be reproduced by reading the complete production execution data, and the production optimization of enterprises is significant, in the prior management system, the generation process of the data is focused, and the data generation process is completely recorded by issuing order data, issuing production arrangement and production instruction data, monitoring the production process, collecting field production data, statistically processing and reporting data and the like, but the stored data is too complete, so that the difficulty in retrieving and looking up part of information is high, the utilization rate of the data is reduced, therefore, the storage process of the production execution data is performed in partial steps, different data are formed in each step according to a set rule, the data are respectively and correspondingly stored in each classification storage unit to form a data set, and a specific data set formed according to a specific rule can reflect one data attribute in a centralized manner, so that the utilization and analysis of the data are more possible.
Specifically, the embodiment further includes a data name assigning unit, configured to assign a main file name uniquely identifying the production execution data to the production execution data according to a data protocol, where the partial main file name is more consistent with the production execution data name in the prior art, and is mainly used for distinguishing complete data, so as to facilitate data reading, and for example, unique distinguishing in a combination manner of a product batch number, a production date, and the like is easier to implement. However, for the data sets in the respective sorting storage units, since the data sets have the purpose of processing and analyzing, the elimination of the repeated data is particularly important, on one hand, the storage space of the data can be saved, and on the other hand, the difficulty of data analysis and processing can be reduced, so that the data name giving unit is further configured to give an auxiliary file name for classifying each data in the data set, the auxiliary file name includes a first identification portion for identifying the source of the production execution data, the first identification portion is mainly used for providing identification information when the source of the production execution data needs to be judged through a single data, the auxiliary file name further includes an extension portion for recording at least two items of information in the data, the single information is used as a basis for sending the data to the single sorting storage unit, for example, when the data in the dispensing process in the production process is taken as an example, and the extension portion records "solidified 07", the information recorded by the extension portion, indicating curing by the device 07, includes both "cure" and "07" information, and therefore this data is stored in the classification storage unit of the process "cure" and the classification storage unit of the device "07", respectively, so that the data set in the classification storage unit of the device "07" can be called when the device "07" needs to be analyzed, and the data set in the classification storage unit of the "cure" can be called when the "cure" process needs to be analyzed. For another example, when data of an operator a in a production process is taken as an example, and the expansion part records "a 05H 2", the information of the expansion part includes three items of information "a", "05" and "H2", where "a" represents the operator a, and "05" represents the fifth year in which the operator a works in the company, and "H2" represents a specific product type, and therefore, the data is stored in the classification storage unit of the operator "a", the year "05" and the classification storage unit of the product "H2", respectively, so that when a skill analysis needs to be performed on an employee with a working year of 5 years, the data set in the classification storage unit of the year "05" can be called, and when a production condition of the specific product "H2" needs to be analyzed, the data set in the classification storage unit of the product "02" can be called; the naming mode is related to the data protocol and can be specifically set in actual use.
In the process of the data application, in order to weaken the analysis influence of the source of the production execution data on the subsequent data, the data application system further comprises a file name secondary giving unit, wherein the file name secondary giving unit is used for extracting the auxiliary file name of each data in each classification storage unit and recording and forming a first identification list, the first identification part is replaced by a second identification part for uniquely identifying the data set source of the data after recording, the second identification part and the extension part rewrite the storage name of the definition data and record and form a second identification list, and the first identification list and the second identification list establish a one-to-one correspondence relationship.
In the actual production process, the situation that the extension parts are consistent easily occurs in different production execution processes, which indicates that the data come from different production execution processes, but the reflected data have certain consistency, and the judgment of the consistency is related to the information reflected by the extension parts, so the embodiment further comprises a data set comparison unit, which identifies the extension parts of the latest data entering each classified storage unit and compares the latest data with the first identification list, when the extension parts exist, the latest data are not recorded, otherwise, the storage names of the data redefined are stored, and by the above method, the repeated recording of approximate data can be effectively avoided, and the processing amount of the data with the same attribute in the analysis and processing processes can be reduced.
As a preferred example of the above embodiment, as shown in fig. 2, the file name secondary assigning unit is further configured to rename the extension portion, and in the naming process, assign a third identification portion that uniquely identifies the extension portion in the corresponding classification storage unit. Similarly, taking the data of the dispensing process in the production process as an example, when the expansion part records "cure 07", it indicates that the curing is performed by the equipment 07, and the information recorded by the expansion part includes two items of information, i.e., "cure" and "07", so this data will be stored in the classification storage unit of the process "cure" and the classification storage unit of the equipment "07", respectively.
As a preferable example of the above embodiment, as shown in fig. 3, the second identification portion and the third identification portion redefine the storage name of the data and record to form a third identification list, and the second identification list and the third identification list establish a one-to-one correspondence relationship. Therefore, in the data analysis and processing process, the complete data can be accurately called and identified through the corresponding relation among the first identification list, the second identification list and the third identification list.
In the invention, the corresponding relation among the first identification list, the second identification list and the third identification list has important significance, the related information of each step of production execution data can be identified through file names in the first identification list and the second identification list, and the third identification list can identify the data quantity in each data set and the information related to the third identification part, so that the third identification list can be used as a basis for data calling.
Preferably, the MES-based production management system further includes a data sending unit, which periodically forms an access link with the latest data in the single-classification storage unit and sends the access link to the system server, so that the server can forward the link, and the latest data is sent to a setting person for manual check, especially check specific steps in the whole production execution data, to manually determine the validity of the data, and the determination result can be used as a basis for sorting the data in the classification storage unit.
When the physical memory is selected for the classified storage unit, the memory type and the memory capacity can be freely selected, but the memory type and the memory capacity have the storage upper limit and the possibility of failure, therefore, the optimal scheme further comprises an alarm unit which is correspondingly configured with the classified storage unit and is used for detecting whether new data is recorded in the classified storage unit within the set time, and when the new data is not recorded, alarm information is sent out, and in the continuous production process, the set time can be set and adjusted according to the past data generation frequency, so that the alarm information is more stable and reliable.
In the production process, production execution data is a result generated after each data model is instantiated, all production is executed according to corresponding models, and specific models comprise an MES overall topological relation model and an MES production link model, wherein the MES production link model is used for executing independent production links, and the MES overall topological relation model describes the topological relation among each MES production link model.
In the preferred embodiment, the MES overall topological relational model library is disposed in the main storage unit, so that the model library can be adjusted and optimized according to the stored complete production execution data, and similarly, the classification storage unit further includes an MES production link model library, so that the model library can be adjusted and optimized according to the specific production links of each step in the whole production execution process. And the respective models correspond to the respective data sets, so that the model correspondence and optimization complexity is reduced.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
