Based on the method, how to reduce maintenance cost and overcome manufacturing errors by using the manufacturing control conditions of the equipment under the condition that the equipment has no major faults or errors in the middle and front stage of the equipment is a problem which needs to be solved.
On the basis, the industrial internet of things system based on product error value correction manufacturing is built based on a five-platform structure, the service platforms are arranged in a rear split platform mode, the service platforms can interact with the user platform through the split platforms of different service platforms, data transmission and processing can be carried out according to different error value data in a classified mode, mutual data are not affected, data processing requirements of all the split platforms are reduced, all the data are integrated and processed according to specific requirements through the total platform of the service platform, the management platform is arranged in a centralized mode, unified processing and transmission are carried out on the integrated data of the total platform of the service platform through one independent platform, and therefore all the data can be coordinated and unified, finally, the data can be transmitted through a centralized type arranged sensing network platform in a unified mode, simultaneous adjustment can be achieved, unified data replacement of the user platform is guaranteed, and production continuity and reliability of the user platform are guaranteed.

It should be noted that, the user platform in this embodiment may be a desktop computer, a tablet computer, a notebook computer, a mobile phone, or other electronic devices capable of implementing data processing and data communication, which is not limited herein. In a specific application, the first server and the second server may be a single server, or may be a server cluster, which is not limited herein. It should be understood that the data processing procedure mentioned in this embodiment may be performed by a processor of the server, and the data stored in the server may be stored in a storage device of the server, such as a hard disk or a memory. In a specific application, the sensor network platform may use multiple groups of gateway servers, or multiple groups of intelligent routers, which are not limited herein. It should be understood that the data processing procedure mentioned in the embodiments of the present application may be processed by the processor of the gateway server, and the data stored in the gateway server may be stored in the storage device of the gateway server, such as the hard disk and the SSD.
In specific applications, the product error value refers to an error value existing between an actual value obtained after detection and a set value based on the set value of the index of the size, thickness, hardness, surface roughness, strength and the like of a product (a part, a component, an assembly, a device and the like) after completing production or completing a certain process, for example, when the length of the product is set to l=1m, if the actual value obtained after detection is l=0.98m, the product error value is l= -0.02 m, and for example, when the hardness of the product is set to hr=40, if the actual value obtained after detection is hr=42, the product error value is hr= +2, wherein "—", "+" is positive or negative relative to the set value.
In actual production, a certain error range exists in the set value, so long as the set value meets the requirement in the error range, but the set value cannot meet the requirement if exceeding the error range, based on the fact, in the embodiment, the manufacturing parameter is directly corrected by utilizing the error value, so that the manufacturing equipment performs manufacturing according to the most preferable set value as a standard, the manufacturing precision of the manufacturing equipment can be ensured, the manufacturing parameter is continuously and permanently optimized, the manufacturing error is reduced, and the product qualification rate is improved.
In some embodiments, in order to ensure that the product error value can find the sub-platform and the object platform of the corresponding service platform, the type feature based on the product error value sends the one or more product error values to the sub-platform of the service platform corresponding to the type feature respectively, where the sub-platform specifically includes:
the product error value is associated with type feature data, and the type feature data at least comprises object platform information, procedure information and type index information;
different first type index identifiers are respectively configured on sub-platforms of different service platforms;
based on the type index information, the user platform respectively sends the one or more product error values to sub-platforms of the service platform corresponding to the first type index identification.
On the basis, after the user platform obtains the product error value, a matching circuit can be found according to the matching result of the type index information and the first type index identifier, and further different product error values can be received and processed through different and corresponding sub-platforms of the service platform, so that classification processing of different data is formed.
It should be noted that, the type index information is information representing an error type of the product error value, for example, in the product error value l= -0.02 m, L (refer to length) may be used as type index information for representing a length error, and at this time, the first type index identifier may also be represented by L, and when matching, the first type index identifier and the second type index identifier may be paired based on the two token information, where, in order to represent different processes or object platforms, further information may be added on this basis to represent further content, for example, the product error value l= -0.02 m may be further represented by xl= -0.02 m, where X may be a corresponding process number or object platform type, for example, X may be a process number 01, 02, or X may be an object platform C (lathe), an object platform Z (drilling machine), etc., and the corresponding first type index identifier may also be synchronously added in this way, thereby forming a data index association.
It should be noted that the object platform information may be information of a manufacturing device for solving the product error value, or may be information of a manufacturing device that may form the product error value in a production process, for example, the object platform information may be a device number, a code, etc. directly, so that corresponding manufacturing devices may be obtained according to the object platform information, so as to facilitate replacement of subsequent manufacturing parameters, for example, a product error value in length, where the manufacturing devices may be a lathe or a sawing machine, and a corresponding lathe or sawing machine may be found in advance according to an actual production situation to be associated with. Similarly, the process information is the process in which the product error value may occur or be resolved, e.g., in terms of hardness, the corresponding process may be a work hardening process (metal melting, material blending), a surface strengthening process (shot blasting, laser shock, rolling), a heat treatment process (quenching, tempering, annealing, carburizing, nitriding, etc.), etc
In some embodiments, since the manufacturing apparatus may be a dual-purpose apparatus, such as a drilling and tapping dual-purpose machine tool, a drilling and milling dual-purpose machine tool, a lying dual-purpose machine tool, a multifunctional machine tool (turning, milling, grinding, sawing), a dry and wet dual-purpose pyrolysis apparatus, a multi-purpose heat treatment furnace, etc., when applied, the apparatus may need to perform different functional roles, but when identified, the common function or the first function thereof is often used as the identification, so for such cases, in this embodiment:
The sub-platforms of different service platforms are also respectively configured with different second type index identifiers; and when the user platform cannot be matched with the first type index identifier based on the type index information, the user platform respectively sends the one or more product error values to sub-platforms of the service platform corresponding to the second type index identifier based on the type index information and the second type index identifier.
Based on the above, the second type index identifier can perform index identification on the second function of the corresponding manufacturing equipment, when the type index information cannot be matched with the first type index identifier, the corresponding manufacturing equipment can be found based on the second type index identifier, and the situation that some manufacturing equipment have multiple functions and cannot be matched is avoided.
It should be noted that the second type index identifier may be one or more, and the plurality of second type index identifiers may be sorted according to the actual function application situation to form a third type index identifier, a fourth type index identifier, and the like.
In some embodiments, the product manufacturing parameter table includes at least product manufacturing parameters corresponding to object platform information; after the management platform receives the product error table, the management platform extracts a product error value and acquires a parameter correction value based on the product error value; and based on the parameter correction value and the object platform information, correcting the corresponding product manufacturing parameters by taking the parameter correction value as correction data, and covering the uncorrected product manufacturing parameters by taking the corrected product manufacturing parameters as final data to form a corrected product manufacturing parameter table.
In this embodiment, the product error value is an error value of the product, and in order to make it more directly used for replacing the product manufacturing parameter, it needs to be converted into a corresponding parameter correction value, for example, the product error value l= -0.02 m is smaller than the set length value by 0.02m, based on which, we need to extract-0.02 m to convert it into a parameter correction value, and because it is smaller, the parameter correction value finally converted should be +0.02, that is, the parameter correction value is added on the basis of the unmodified product manufacturing parameter, that is, the set value l=100.02 m, that is, the final product manufacturing parameter, that is, the set value l=100.02 m.
It should be noted that, some product error values may not be directly converted from the set value, for example, for the error value of the hardness, the heating temperature of the heat treatment may be highly changed, and at this time, the parameter correction value of the error value of the hardness may not be directly converted from the set value of the heating temperature, which is based on the following:
the management platform is pre-stored with an error conversion table, the error conversion table at least comprises object platform information, process information and an error conversion formula, and the object platform information, the process information and the error conversion formula are in one-to-one correspondence; after the management platform obtains the product error value, an error conversion formula is obtained based on the object platform information and the process information, the product error value is brought into the conversion formula to be converted, the manufacturing parameter deviation value corresponding to the product error value is obtained, and the manufacturing parameter deviation value is used as a parameter correction value.
In this embodiment, the error conversion formula may be set in advance according to the corresponding error value data, type, relationship, etc., for example, for the external dimension, thickness, diameter, etc., which may be obtained directly by data addition and subtraction, the formula may be adopted:
X=﹣（L2）
wherein X is a manufacturing parameter deviation value, and L2 is a product deviation value.
For example, if the product error value with the length is l= -0.02 m, the manufacturing parameter deviation value x=0.02 can be obtained by using the formula, so that the manufacturing parameter deviation value is directly added to the set value as the parameter correction value during correction.
For other product error values, such as errors of hardness, strength, surface roughness, etc., the errors may be affected by corresponding manufacturing conditions, i.e., an error conversion formula may be set or given in advance for the relationship between the manufacturing conditions and the errors.
For example, the article "tempering curve of quenched steel and empirical formula for calculating tempering temperature" in the prior art (the author mainly stands for ) mentions a formula related to the relative relation between tempering temperature and hardness of different steel grades, and further obtains a temperature value that a hardness unit corresponds to needs to be raised and lowered, based on which the following formula can be obtained by using the prior art:
Y=C×K
Wherein Y is a manufacturing parameter deviation value, C is a product deviation value (positive and negative signs are reserved) of hardness, and K is a temperature value which is required to be increased and decreased corresponding to a hardness unit. Therefore, when the manufacturing parameter deviation value is obtained, the temperature deviation value can be directly added or subtracted with the set temperature value, and the adjusted temperature set value, namely the corrected product manufacturing parameter, is obtained.
It should be noted that, the error conversion formula is obtained according to the specific type of the error, the corresponding relation of the error product, the manufacturing equipment, and the like, and because the above formulas are converted by using standard formulas, empirical formulas or establishing actual formulas according to actual conditions in actual use, the embodiment only provides the error conversion principle for the two formulas, so long as the error and the manufacturing parameters can be associated and the relation between the error and the manufacturing parameters can be found, which can be realized in the actual production process, and the error conversion formula can be obtained without the need of creative labor based on the prior art, so the embodiment is not exhaustive any more, and the skilled person can utilize the function method, the multi-element equation solution, and the like to set and derive the required formulas by himself according to the actual conditions.
The second embodiment of the invention provides an industrial internet of things system based on the product error value correction and manufacture, and also provides a control method of the industrial internet of things system based on the product error value correction and manufacture, the control method comprises the following steps:
When the user platform acquires one or more product error values, the one or more product error values are respectively sent to sub-platforms of a service platform corresponding to the type features based on the type features of the product error values;
