Description

Technical Field

[0001] The present invention relates to the field of production management systems, and particularly to a MES system and a method for using the same. Background Art

[0002] MES (Manufacturing Execution System) is a production information management system for the execution layer of a manufacturing enterprise workshop. Please refer to Figure 1 , Figure 1 FIG. is an architecture diagram of a MES system in the prior art. As Figure 1 shown, the mainstream MES system 10 on the market currently includes a system terminal 11 and a plurality of production operation terminals 12 connected by communication. When in use, a series of complex basic data maintenance needs to be performed on the system terminal 11 first, including products to be produced, required processes, production lines, workstations, etc., to complete basic data modeling. After that, corresponding input interfaces will be generated on the plurality of production operation terminals 12 connected to the system terminal 11, and the current process station, product model, process to be recorded soon, etc. will be displayed on the input interfaces. For large enterprises, the number of production operation terminals 12 is large and the process flow is complex. The method of first completing basic data modeling on the system terminal 11 and then configuring the input interfaces of the plurality of production operation terminals 12 can conveniently and quickly record production data and form a statistical dashboard during the production process. However, for some small and medium-sized enterprises, their production processes are relatively simple or the production scale is small (for example, only one or two production operation terminals 12). The method of first performing huge and complex basic data maintenance / configuration on the system terminal 11 and then enabling the production operation terminals 12 to generate input interfaces will have problems such as too high investment in basic data maintenance / configuration, complex operation, and high comprehensive use cost after purchasing the entire MES system 10 and only applying it to a small number of production operation terminals 12. Therefore, how to design a MES system to flexibly adapt to the actual production of enterprises is a problem that needs to be solved in the industry. Summary of the Invention

[0003] The purpose of the present invention is to provide a MES system and a method for using the same, which can be flexibly applicable to the actual production of enterprises, for example, applicable to the production information management of small and medium-sized enterprises with relatively simple production processes or small production scales, with simple operation and significantly reduced enterprise costs.

[0004] To achieve the above object, the present invention provides a MES system, which includes at least one production operation terminal and a system terminal. Each production operation terminal has a custom interface, and the system terminal is communicatively connected to the at least one production operation terminal. Among them, before production, each production operation terminal customizes a plurality of required input fields on the custom interface to generate a personalized input interface. The plurality of input fields at least include a product input field and a current process station input field. The product input field is used to input product information, and the current process station input field is used to input current process station information. During production, the at least one production operation terminal inputs production data through the input interface and transmits it to the system terminal. The time when each product is input through the input interface during production is defined as the output time corresponding to each product. The production data at least includes the product information, the current process station information, and the output time. The system terminal receives and aggregates the production data transmitted by the at least one production operation terminal to reverse-deduce the process stations required for the currently produced product, and automatically generates a production report by integrating the production data of each process station.

[0005] As an optional technical solution, the system terminal reversely deduces the details and sorting of the process stations required for the currently produced product according to the sequence of the output times of the first-piece products corresponding to each process station in the production data transmitted by each production operation terminal.

[0006] As an optional technical solution, during production, each product has an identification number. After the corresponding process is completed at each process station, the corresponding production operation terminal scans the identification number and inputs it into the product input field as the product information.

[0007] As an optional technical solution, the plurality of input fields include at least one pre-stored field, and the at least one pre-stored field includes the current process station input field. Each production operation terminal pre-stores the current process station information in the current process station input field.

[0008] As an optional technical solution, the plurality of input fields further include a product model input field, which is used to input the product model currently being produced. The production data further includes the product model currently being produced. The product model input field is a real-time input field. During production, for each product, each production operation terminal inputs the product model currently being produced through the product model input field; or, the product model input field is a pre-stored field, and each production operation terminal pre-stores the product model currently being produced in the product model input field.

[0009] As an alternative technical solution, after the system terminal receives the discrete production data transmitted by the at least one production operation terminal, it determines whether the product information in each production data has the same keyword. If so, the production data with the same keyword in the product information is taken as the same group information. In the group information, the system terminal generates a production report after performing logical classification according to different fields. The production report includes the details of the process stations required for the currently produced product and the current output of each process station.

[0010] As an alternative technical solution, each product has a product model. During the production process, after each process station completes the corresponding process, the corresponding production operation terminal enters the product model in the product entry field as the product information.

[0011] As an alternative technical solution, the multiple entry fields further include an identity code entry field. Each product has an identity number. After each process station completes the corresponding process, the corresponding production operation terminal also enters the identity number in the identity code entry field and then transmits it to the system terminal.

[0012] In addition, the present invention also proposes a method for using a MES system. The MES system includes at least one production operation terminal and a system terminal. The system terminal is communicatively connected to the at least one production operation terminal, and each production operation terminal has a custom interface. The method for using includes,

[0013] Before production, each production operation terminal customizes multiple required entry fields on the custom interface to generate a personalized entry interface. The multiple entry fields at least include a product entry field and a current process station entry field. The product entry field is used to enter product information, and the current process station entry field is used to enter current process station information.

[0014] During the production process, the at least one production operation terminal enters production data through the entry interface and transmits it to the system terminal. Define the time when each product is entered on the entry interface as the output time of each product. The production data at least includes the product information, the current process station information, and the output time. And

[0015] The system terminal receives and aggregates the production data transmitted by the at least one production operation terminal to reverse-engineer the process stations required for the currently produced product, and automatically generates a production report by integrating the production data of each process station.

[0016] As an alternative technical solution, in the method for using, the system terminal reversely deduces the details and sorting of the process stations required for the currently produced product according to the order of the output times of the first-piece products corresponding to each process station in the production data transmitted by each production operation terminal.

[0017] The MES system provided by the present invention and its usage method. Before production, each production operation terminal customizes its own input interface. During production, actual production data is input through the input interfaces of each production operation terminal. The discrete production data continuously transmitted by each production operation terminal forms a data stream at the system end. The system end automatically generates production reports from the data stream according to preset logic for relevant personnel to refer to. The present invention does not require huge and complex basic data maintenance before production, but instead infers the product process flow and the like from the data in the data stream to form data reports, which can flexibly adapt to the actual production of enterprises. Especially for the production informatization management of small and medium-sized enterprises with relatively simple production processes or small production scales, it is simple to operate, highly efficient, and can significantly reduce the production costs of enterprises.

[0023] To further understand the purpose, structure, features, and functions of the present invention, the following will be described in detail in conjunction with the embodiments.

[0024] Please refer to Figure 2 , Figure 2 which is the architecture diagram of the MES system of the present invention. As Figure 2As shown, the MES system 100 of the present invention includes a system terminal 110 and at least one production operation terminal 120. Each production operation terminal 120 has a customized interface. Before production, each production operation terminal 120 customizes a plurality of required input fields on the customized interface to generate a personalized input interface 121. The plurality of input fields at least include a product input field and a current process station input field. The product input field is used to input product information, and the current process station input field is used to input current process station information. During production, the at least one production operation terminal 120 inputs relevant production data through its respective input interface 121 and transmits it to the system terminal 110. Further, define the time when each input interface 121 inputs each product during production as the output time corresponding to each product. The aforementioned production data at least includes product information, current process station information, and output time. The system terminal 110 receives and collates the production data transmitted by the at least one production operation terminal 120 to reverse-infer the process stations required for the currently produced product, and automatically generates a production report by integrating the production data of each process station.

[0025] In one embodiment, there are multiple workstations in a factory. A production operation terminal 120 can be selectively configured on each workstation. For example, a production operation terminal 120 is configured on each workstation, or a production operation terminal 120 is configured on individual key workstations. By using the production operation terminal 120 to record production data in a timely manner, the production data on the corresponding workstation can be transmitted in a timely manner.

[0026] In the MES system 100 of the present invention, a customized input interface 121 is defined in the production operation terminal 120, such as the specific product produced at the current workstation, which process station it belongs to, or even which production line it belongs to, etc. When customizing the input interface 121, the number of required fields can be selected on the customized interface, and the name of each field can also be defined by oneself. For example, it includes a product field, a current process station field, etc. The number of fields and the field names are not limited to this.

[0027] For the MES system 100 of the present invention, before production, after each production operation terminal 120 customizes its own input interface 121, during the production process, actual production data is input through the input interface 121 of each production operation terminal 120. The discrete production data continuously transmitted by each production operation terminal 120 forms a data stream at the system end 110. The system end 110 automatically generates production reports from the data stream according to preset logic for relevant personnel to refer to, and conducts real-time dynamic monitoring on indicators such as order completion status, product yield, equipment operation, and raw material consumption, helping enterprise managers promptly discover the deviation between "plan" and "actual" and improve management efficiency. The present invention does not require huge and complex basic data maintenance before production. Instead, it infers the product process flow and other information from the data in the data stream to form a data report, which can flexibly adapt to the actual production of the enterprise.

[0028] The MES system 10 in the prior art requires a series of complex basic data maintenance at the system end 11 before production. After completing the modeling, the input interface of each production operation terminal 12 is configured and generated downward, so that the production operation terminal 12 can input data during the production process. Then, the system end 11 combines the data input by the production operation terminal 12 during the production process and the basic data configuration to generate statistical charts. The MES system 100 of the present invention adopts a completely opposite method to the MES system 10 in the prior art. It does not perform basic data maintenance at the system end 110 in advance. Data information such as the products produced, output, and yield at each process site is inversely aggregated by the foregoing at least one production operation terminal 120 during the production process, that is, data is first input through each production operation terminal 120, and then the basis required by the MES system is formed. That is to say, the MES system 10 in the prior art is a standard mode of configuring each discrete point (each production operation terminal 12) downward from a centralized (system end 11) mode; the MES system 100 of the present invention is a structure that grows a centralized (system end 110) structure downward from an edge (each production operation terminal 120) mode. In this way, it can more flexibly adapt to the actual production of enterprises (especially small and medium-sized enterprises).

[0029] The MES system of the present invention does not require a large and complex underlying configuration logic like the MES systems in the prior art. Instead, it only needs to set an input interface 121 on the production operation terminal 120. During the production process, the MES system 100 can be automatically formed through data streams from several production operation terminals 120, which can flexibly adapt to the actual production of the enterprise. If there is only one production operation terminal 120 in the factory, the MES system 100 can also be formed by this single production operation terminal 120. If there are multiple production operation terminals 120 in the factory, the MES system 100 can also be formed by these multiple production operation terminals 120. Each production operation terminal 110 can input the production information that can be obtained according to the actual process station it belongs to during the actual production process, and does not need to input the production information that has not been obtained, with flexible operation. And because it is based on a discrete mode and finally forms a centralized effect, when purchasing the MES system 100, the enterprise can purchase based on the number of production operation terminals 120 (or considered as the number of workstations), which reduces the comprehensive usage cost and enables the MES system 100 to flexibly provide corresponding functional services according to the production scale of the enterprise.

[0030] In one embodiment, the production operation terminal 120 customizes multiple input fields required on the custom interface. The multiple input fields at least include a product input field and a current process station input field. Further, it can also include, for example, an order input field, etc., and then form a corresponding input interface 121. During the production process, each production operation terminal 120 continuously inputs production information through the customized input interface 121 and transmits it to the system end 110. After receiving these discrete data, the system end 110 can infer the process stations required for the currently produced product based on the input time of the production data. Specifically, the system end 110 infers the details and sorting of the process stations required for the currently produced product according to the sequence of the output times of the first-piece products corresponding to each process station in the production data transmitted by each production operation terminal 120.

[0031] For example, the MES system 100 has three production operation terminals 120, which are defined as the first production operation terminal, the second production operation terminal, and the third production operation terminal. The production data transmitted by each production operation terminal includes the current process station information and the output time of each product. Suppose the first production operation terminal corresponds to process station A, and the output time of the first product it transmits is 8:00; the second production operation terminal corresponds to process station B, and the output time of the first product it transmits is 8:30; the third production operation terminal corresponds to process station C, and the output time of the first product it transmits is 9:00. Then it can be inferred that the details of the process stations required for the currently produced product include process station A, process station B, and process station C, and the sequence of each process station is: process station A -> process station B -> process station C.

[0032] Further, the system end 110 can use the field names of the input interfaces 121 of each production operation terminal 120 as one of the judgment logics. If there are the same keywords in the field names (such as the same product names in the product fields, etc.), the data entered with the same keywords is statistically analyzed as a group information. For example, after the system end 110 receives the discrete production data transmitted by the foregoing at least one production operation terminal 120, it determines whether the product information in each production data has the same keyword. If so, the production data with the same keyword in the product information is regarded as the same group information. In this group information, the system end 110 generates a production report after logical classification according to different fields. The production report includes the details of the process stations required for the currently produced product and the current output of each process station. In this way, the system end 110 logically classifies the discrete production data transmitted by the foregoing at least one production operation terminal 120 according to the input fields to generate a preliminary statistical production report. In actual operation, the preliminary statistical production report can also be analyzed to further generate a detailed statistical report, such as the production progress of each work station, the overall progress of the work order, etc.

[0033] In the present invention, before production, after customizing the respective input interfaces 121 on each production operation terminal 120, data can be continuously entered and transmitted to the system end 110 during the production process. The system end 110 gradually combines these data into a data stream to form a database, and then generates a production report based on this database, thus eliminating the need for the large and complex series of basic data configurations that need to be performed on the system end 11 in the prior art, and can also automatically generate a production report. In an embodiment, the modules for forming the database and forming the production report can be independent modules that communicate with each other. In the present invention, they are collectively referred to as the system end 110.

[0034] In one embodiment, during the production process, each product has a unique identification number, such as a barcode or a QR code. After each process station completes the corresponding process, the corresponding production operation terminal 120 posts the transaction by scanning the identification number. During the posting, the identification number will be entered into the product entry field as the product information.

[0035] In one embodiment, the plurality of input fields include at least one pre-stored field, and the at least one pre-stored field includes the current process site input field, and each production operation terminal pre-stores the current process site information in the current process site input field. Generally, when a certain station produces a certain product, the current process site to which it belongs generally does not change. In this case, this input field can be set as a pre-stored field in the custom interface. During the production process, this input field can be automatically entered with the pre-stored information by default, which is convenient for the user's operation.

[0036] In one embodiment, the plurality of input fields also include a product model input field, and the product model input field is used to input the product model of the current production, and the aforementioned production data may also include the product model of the current production. The product model input field may be a real-time input field, and during the production process, for each product, each production operation terminal 120 inputs the product model of the current production through the product model input field. In another embodiment, when a certain workstation produces a certain product, the production model of the current production will not change within a certain production period. In this way, the product model input field may also be a pre-stored field, and each production operation terminal 120 pre-stores the product model of the current production in the product model input field. During the production process, the product model input field may automatically enter the pre-stored information by default, which is convenient for the user's operation.

[0037] In the aforementioned embodiment, the product information is the identification number on each product. In actual operation, it is not limited to this. In one embodiment, each product has a product model. During the production process, after each process site completes the corresponding process, the corresponding production operation terminal 120 enters the product model in the product entry field as the aforementioned product information. Furthermore, the multiple entry fields may also include an identity code entry field. Each product has an identity number. After each process site completes the corresponding process, the corresponding production operation terminal 120 also enters the identity number in the identity code entry field and transmits it to the system end 110.

[0038] The process flow of a certain product in the present invention does not need to be preset. Instead, it is randomly generated directly during the production process as the production information of each work station is continuously input. Moreover, the system end 110 automatically grabs the information belonging to the same group according to the production information transmitted by each production operation terminal 120 and then processes it to form a production report.

[0039] The following is an illustration by way of example.

[0040] Suppose that currently the factory needs to produce 1000 pieces of product L according to order A. There are work stations A, B, C, and D for manufacturing product L. Each of work stations A, B, C, and D has a production operation terminal 120. Before production, a custom input interface 121 is set for each production operation terminal 120 on each work station. The multiple input fields of the input interface 121 include a product input field, an order input field, an order quantity input field, and a current process station input field. In this embodiment, the product input field is a real-time input field for inputting the product model currently being produced. The order input field, the order quantity input field, and the current process station input field can be pre-stored fields, and each production operation terminal 120 can pre-store corresponding information in the corresponding fields. Then production begins, and each production operation terminal 120 continuously inputs production data.

[0041] Since the product information in the production data transmitted by the production operation terminals 120 corresponding to each work station is all product L, the system end 110 will take the data information input by the production operation terminals 120 corresponding to work stations A, B, C, and D as a group of information for processing based on the existence of the same keyword "product L" in the product information.

[0042] Next, the system end 120, according to the sequence of the output times of the first pieces of products corresponding to the four process stations in the production data transmitted by the four production operation terminals 120, reversely infers the details of the process stations required for the currently produced product and the sorting of the process stations. If the system end 110 confirms from the data in the database that the time when the production operation terminal 120 on work station A inputs the first piece of product L is 8:00; the time when the production operation terminal 120 on work station B inputs the first piece of product L is 9:00; the time when the production operation terminal 120 on work station C inputs the first piece of product L is 10:00, and the time when the production operation terminal 120 on work station D inputs the first piece of product L is 11:00. In this way, by sorting according to the sequence of the output times of the first pieces of products, it can be confirmed that the details of the production process of product L include work stations A, B, C, and D, and the sequence among the four is: work station A -> work station B -> work station C -> work station D.

[0043] Further, the system side 110 has counted that, up to now, the production operation terminal 120 corresponding to Station A has transmitted 400 pieces of production data to the system side, the production operation terminal 120 corresponding to Station B has transmitted 350 pieces of production data to the system side, the production operation terminal 120 corresponding to Station C has transmitted 300 pieces of production data to the system side, and the production operation terminal 120 corresponding to Station D has transmitted 250 pieces of production data to the system side. Thus, it can be deduced that the output of Station A is 400 pieces, the output of Station B is 350 pieces, the output of Station C is 300 pieces, and the output of Station D is 250 pieces. At this time, the production report initially compiled by the system side 110 is as shown in Table 1 below. There is no longer a need, as in the prior art, to first perform basic data configuration in the MES system, such as the quantity to be produced at each of the four stations required for the production of Product L currently, and even the machines and program parameters applied at each station, etc. Only after the configuration will a corresponding input interface be formed on the production operation terminal 12 corresponding to each station. In this way, the operation is convenient and can flexibly adapt to the actual production needs of the enterprise.

[0046] In addition, the present invention also proposes a usage method of an MES system. The MES system 100 includes a system side 110 and at least one production operation terminal 120. The system side 110 is communicatively connected to at least one production operation terminal 120, and each production operation terminal has a custom interface. Please refer to Figure 4 , and the usage method includes

[0047] S110, before production, each production operation terminal 120 customizes a plurality of required input fields on the custom interface to generate a personalized input interface 121. The plurality of input fields at least include a product input field and a current process station input field. The product input field is used to input product information, and the current process station input field is used to input current process station information;

[0048] S120, during production, at least one production operation terminal 120 inputs relevant production data through its own input interface 121 and transmits it to the system side 110. Define the time when each product is input on the input interface 121 as the output time corresponding to each product. The production data at least includes the product information, the current process station information, and the output time; and

[0049] S130, the system side 110 receives and collates the production data transmitted by at least one production operation terminal 120 to deduce the process stations required for the currently produced product, and automatically generates a production report by integrating the production data of each process station.

[0050] Furthermore, the system side 110 infers in reverse order the details of the process stations required for the currently produced product and the sorting of the process stations according to the sequence of the output times of the first-piece products corresponding to each process station in the production data transmitted by each production operation terminal 120.

[0051] For the MES system and its usage method provided by the present invention, before production, each production operation terminal customizes its own input interface. During production, the actual production data is input through the input interfaces of the production operation terminals. The discrete production data continuously transmitted by each production operation terminal forms a data stream at the system side. The system side automatically generates a production report from the data stream according to the preset logic for relevant personnel to refer to. The present invention does not require huge and complex basic data maintenance before production, but infers the product process flow, etc. from the data in the data stream to form a data report, which can flexibly adapt to the actual production of the enterprise. Especially for the production information management of small and medium-sized enterprises with relatively simple production processes or small production scales, the operation is simple and efficient, and it can significantly reduce the production cost of the enterprise.

[0052] Certainly, the present invention can also have many other embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and deformations according to the present invention. However, these corresponding changes and deformations should all fall within the protection scope of the appended claims of the present invention.

The product input field is used to enter product information, and the current process station input field is used to enter current process station information. During production, the at least one production operation terminal enters production data through the input interface and transmits it to the system end. Define the time when each product is entered in the input interface as the output time of each product. The production data at least includes the product information, the current process station information, and the output time. The system end receives and aggregates the production data transmitted by the at least one production operation terminal to reverse-deduce the process stations required for the currently produced product, and automatically generates a production report by integrating the production data of each process station. Among them, the system end reversely deduces the details and sorting of the process stations required for the currently produced product according to the order of the output times of the first-piece products corresponding to each process station in the production data transmitted by each production operation terminal.
