Description

MES building system for smart factory {MES BUILDING SYSTEM FOR SMART-FACTORY}

The present invention relates to a smart factory, and more specifically, to a system that implements a production execution function in a smart factory.

A smart factory is an intelligent production plant that improves productivity, quality, and customer satisfaction by applying information and communication technology (ICT) combined with digital automation solutions to the production process such as design, development, manufacturing, distribution, and logistics. It is an intelligent production plant that improves productivity, quality, and customer satisfaction. This refers to a factory that can install the Internet of Things (IoT) to collect process data in real time, analyze it, and control it according to the intended purpose.

Smart factories have the advantage of minimizing human intervention and not being limited by time, making them particularly easy to apply to manufacturing. In addition, because it is highly effective compared to the input cost, when converting an existing factory into a smart factory, the manufacturing sector is often started first. An example of a smart factory in this manufacturing sector is disclosed in ‘Patent Document 1’, and Figure 1 is a configuration diagram thereof. A typical smart factory in the manufacturing sector consists of a standard management unit (1) that manages control standards for the process, an information collection unit (3) that acquires values sensed by sensors while the process is performed, and a monitoring unit (5) that monitors the control object. , It is composed of an event detection unit (7) that detects when an event occurs in the control object, and a control unit (9) that executes a command corresponding to the control standard for the control object.

When smart factories are implemented with limited resources and costs, the focus is on process automation. In this case, the supply and distribution of raw materials and manpower are often carried out by humans as they were before.

In this case, it is difficult for the data derived from the smart factory's automatic production process to be delivered to the material department in charge of raw materials or the human resources department in charge of manpower, and the materials department or human resources department ultimately collects data from devices on the production line as was done in the conventional factory system. Since the data must be received and processed directly or requested from the production line manager for processing, there is a problem that bottlenecks occur in the raw materials, human resources, and logistics sectors other than the manufacturing sector, resulting in inefficiency.

Hereinafter, the MES construction system for a smart factory according to the present invention will be described in detail with reference to the attached drawings.

To help understand the MES construction system for a smart factory according to the present invention, the smart factory that is the target of the MES construction system for a smart factory according to the present invention will first be described.

Figure 2 is a configuration diagram of a smart factory that is the target of the MES construction system for a smart factory according to the present invention. The smart factory is composed of a PC (10), a PLC (20), and factory equipment 30, and the PC (10) Receives an analog signal or digital signal {AI (Analog Input), DI (Digital Input)} from the factory equipment 30 through the PLC 20 and sends an analog signal or digital signal to the factory equipment 30 through the PLC 20. Signals are output {AO (Analog Output), DO (Digital Output)} to enable the factory equipment 30 to perform automatic production.

The PC 10 is installed with the MES construction system for a smart factory according to the present invention to monitor the factory equipment 30 and issue pre-programmed commands based on various sensed instrument values such as temperature, humidity, and motor speed accompanying monitoring. It is a component transmitted to the PLC (20).

The PLC (20) is a component that stores commands that define each operation and sequence to be performed by the factory equipment (30), and what to do in case of a failure. ) is controlled.

Factory equipment 30 is a component provided in a factory and performs actual manufacturing activities, and refers to reactors, tanks, motors, pumps, pipes, valves, etc.

For reference, analog input (AI) refers to analog signals such as temperature, weight, and pressure transmitted from factory equipment (30) to PLC (20) and PC (10), and analog output (AO) refers to analog signals such as temperature, weight, and pressure transmitted from factory equipment (30) to the PLC (20) and PC (10). ) refers to an analog signal transmitted from the PC (10) and PLC (20) to the factory equipment (30) in order to operate at set values such as temperature, pressure, and motor speed. For example, when the PC (10) commands the PLC (20) to rotate the motor at a certain speed (rpm), the PLC (20) converts this into a current signal of a certain value and transmits it to the motor, so that the motor operates at the PC ( It rotates at the speed commanded in 10). Digital input (DI) is an on or off signal transmitted from the factory equipment 30 to the PLC (20) and PC (10), and the digital output (DO) is a signal transmitted from the PC (10) and PLC (20) to the factory equipment (30). ) is an on or off signal transmitted to For example, signals that turn on or off motors or lights in a factory can be digital inputs or outputs.

Figure 3 is a menu screen of the MES construction system for a smart factory according to the present invention. The MES construction system for a smart factory according to the present invention includes a drawing unit 100 showing the smart factory, the status of the drawn factory equipment or the raw materials in the equipment. An input/output window display unit 200 that displays the amount of, a programming unit 300 that programs the operation of factory equipment, a process setting unit 400 that sets the connection status between facilities, and departments other than the manufacturing department, such as the materials department and human resources department ( (hereinafter referred to as 'department other than manufacturing') and a table preparation unit 500 that creates a table for transmitting and receiving data.

The drawing unit 100 is a component that connects and shows factory equipment for implementing a smart factory, and icons of factory equipment such as reactors, tanks, motors, pipes, and valves are provided. Figure 4 is an example of a smart factory shown in the drawing unit, including first to third tanks 111 to 113 in which raw materials are stored, and a reactor that receives raw materials from the first to third tanks 111 to 113 and mixes them. 120), a stirring motor 130 for stirring the inside of the reactor 120, a fourth tank 114 for storing the reacted product, a pipe 140 connecting the tank and the reactor, and a transfer motor provided in the pipe 140 It is a chemical manufacturing smart factory consisting of (150, 151) or valves (160 ~ 162). In other words, the factory equipment constituting the smart factory and their connection relationships can be defined through the drawing unit 100.

Figure 5 is a list of factory equipment provided in the drawing unit of the MES construction system for a smart factory according to the present invention, where the switch item indicates whether or not it generates a switching signal that can be used as an input signal for other factory equipment, and the contact point Designated items indicate contact points, that is, whether they can be tied to other factory equipment to react to the same signal. Contact points are not specified in all factory equipment. For example, reactors, tanks, and heat exchangers basically do not have contact points. In the case of motors, the output must be connected somewhere, and in the case of conveyors, both sides must be connected, so basically contact points are required. there is. However, since reactors or tanks without basic contact points sometimes operate in synchronization with other factory equipment, it is possible to designate contact points in these cases.

The input/output window display unit 200 is a component that displays an instrument window showing production-related values, such as the status value of each factory equipment of the smart factory shown in the drawing unit 100, the amount of raw materials, and the production volume, as shown in Figure 4. As shown, the status of factory equipment or raw materials can be monitored by matching the instrument window 210 to each factory equipment. The instrument window 210 set in the input/output window display unit 200 is linked to the table created in the table creation unit 500 to enable implementation of the production execution function in the present invention. Figure 6 shows an analog instrument window as an example of an instrument window displayed in the input/output window display unit.

The programming unit 300 is a component that allows the creation of a program that allows the operation of factory equipment to be performed sequentially or according to conditions monitored in a window set in the input/output window display unit 200. Programming when operating the smart factory in FIG. 4 is, for example, ① inserting 100 kg of raw material 1 from the first tank 111 into the reactor 120, and ② loading the second tank 112 with the first transfer motor 150. After adding 50 kg of raw material 2 to the reactor 120, ③ drive the stirring motor 130 to stir and then stop, ④ wait for 30 minutes, and ⑤ add 10 kg of raw material 3 from the third tank 113 to the reactor 120. It can be composed of a series of commands such as ⑥ driving the stirring motor 130 to stir, and then ⑦ immediately driving the second transfer motor 151 to transfer the finished product to the fourth tank 114. there is.

The contact point described above can be used in this process. For example, since raw material 1 and raw materials 2 and 3 should not be input at the same time, the first valve 160 of the outlet pipe of raw material 1 and the second valve 160 of the outlet pipe of raw materials 2 and 3 . A contact point is assigned to the third valve (161, 162), and the contact point value of the first valve (160) and the second. The contact value of the third valves 161 and 162 has an exclusive logic value. For example, when the digital input of the first valve 160 is on, the smart factory is set up so that the smart factory is driven only when the digital input of the second valve 161 and the third valve 162 are off. Malfunction can be prevented.

The process setting unit 400 is a component that sets the process in the factory equipment shown in the drawing unit 100. In particular, when there is a condition for simultaneous operation or exclusive operation (simultaneous operation is not possible), the process setting unit 400 establishes a contact point with the relevant factory equipment. It is highly useful when specified to enable simultaneous or exclusive operation. The contact point can be set in factory equipment as exemplified above when explaining the programming unit 300.

The table creation unit 500 is a component that enables the creation of a table that transmits and receives data with departments that play a role other than manufacturing and provide resources for manufacturing, such as raw materials and manpower. The table is a generally well-known table. Like Excel, it consists of a set of cells with alternating horizontal rows and vertical columns. Inside the cells of the table, there is a gauge window that shows the status of factory equipment or the amount of raw materials formed using the input/output window display unit 200, a calculation window that displays the numbers displayed in the gauge window as calculated values, buttons for executing commands, images, etc. may be included. Here, a button refers to a graphic image that synchronizes the execution of a specific command, such as data entry, modification, deletion, and file saving, to the click of the button, so that the corresponding command is executed when the button is clicked. In other words, the essence of MES construction indicated in the name of the present invention is the creation of such tables and data processing using buttons.

Figures 7 and 8 are examples of tables created to identify raw materials, product receipts and withdrawals, and product recipes in the smart factory of Figure 4.

In the present invention, a special function is provided in the table so that the manufacturing department can easily exchange data with departments other than manufacturing and smoothly perform the production execution function. Figure 9 shows buttons capable of performing special functions provided by the present invention. In the present invention, the master↔detail button 510, table↔input window button 520, file→table button 530, file search→ The functions of the table button 540, table→file button 550, and data input window→file button 560 are defined and data input/output, display, and storage are performed accordingly.

First, the master↔detail button 510 is a component that facilitates data input and output between the master table and the detail table in a table set consisting of the master table and the detail table. Figure 10 is an example of a master table and a detail table that can be viewed when clicking the master↔detail button. The detail table 512 is a table containing detailed data, and the master table 511 is only some data of the detail table. This table is briefly displayed. In order to use the master↔detail button 510, the master table 511 and the detail table 512 must first be created using the table creation unit 500. Initially, all cells in the master table 511 and detail table 512 will be empty.

First, as shown in FIG. 10, the detail table 512, which will contain detailed data, displays the input date, company code, company name, location, person in charge, contact information, etc. in the row of the master table 511 (513, serving as a label). ) and enter specific data such as entry date and company code in the instrument window. Specific data such as specifications and unit prices of valves, pipes, etc. can be entered into cell 514 of the detail table 512 without an instrument window. Next, when you click the Master↔Detail button (510), an input window appears to enter the file name to save the data. After entering the save file name, click the master table (511) and the detail table (512) sequentially to activate them, and the detail table ( 512), when you sequentially click on the instrument windows that will form the rows of the master table 511, the names of the instrument windows, such as input date and company code, are displayed in the master table 511, and thus the master table 511 and the detail table 512 The form of is completed. Afterwards, when specific data such as raw materials and personnel are entered into the detail table 512 and the master↔detail button 510 is clicked, the data in the detail table 512 is linked to each row of the master table 511 and stored in the saved file. It is saved, and the saved file created in this way is delivered to departments other than manufacturing, making it possible to purchase materials, hire personnel, etc. That is, in the present invention, the master table 511 and the detail table 512 can be created in a free format, and data input, modification, and storage can be easily performed by clicking the master↔detail button 510. . In addition, the master table 511 and detail table 512 can be created in departments other than manufacturing, and the saved file created in this way is delivered to the manufacturing department so that the master table 511 and detail table 512 can be created from above. You can enter and edit data using the same method as described. In other words, departments other than manufacturing can request and receive data in the required table format.

The table↔input window button 520 is a component that facilitates data input into the table and eases display restrictions. Figure 11 is an example of a table and an input window that can be seen when the table↔input window button is clicked. Data entered into the input window 522 is stored in the table 521 by clicking the table↔input window button 520. Because it is moved and saved, it is possible to save the table after checking with the entire data displayed. As can be seen in <Employee Personal Information> in Figure 11, when writing letters or numbers in a table, there is an inconvenience in that the entire letters or numbers are not displayed due to the small size of the table. When you click on a specific row of a table (521) such as <Employee Personal Information>, the contents of each cell of the specific row are displayed in the large input window (522). After editing the contents in the input window (522), click the Table↔Input Window button. The function of the table↔input window button 520 is that when you press 520, the modified content is updated in a specific row of the table 521, allowing the table 521 to be modified. That is, by writing the contents in the input window 522, clicking on a specific row of the table 521, and then clicking the table↔input window button 520, the contents of the input window 522 are stored in a specific row of the table 521. It is listed in In this way, the table ↔ input window button 520 can easily input new contents such as plural raw material data and personnel data. In addition, when you click on a specific row of the table 521, the contents written in each cell of the specific row are displayed in the input window 522, so after editing the contents in the input window 522, the row of the table 521 and the table ↔ input window are displayed. By sequentially clicking buttons 520, you can modify the contents of a specific row or easily create other rows with much of the same data as a specific row and store them in the table 521 (for example, raw material 1, 100 kg, June 2023). You can easily create rows with different raw material names, such as Raw Material 2, 100 kg, 2023. 6. 21.).

The File → Table button 530 is a component that reads a file and displays it in table form. When you click the File → Table button 530, the folder containing the file is displayed, and when you select and open the file, the file contents are displayed in table form. do. Therefore, the format of the file that can be read with the File → Table button (530) must be csv (comma separated variables), but in the present invention, the files created with the Master ↔ Detail button 510 and the Table ↔ Input Window button 520 are Since they are all stored in csv format as a table, there is no problem in reading the file created in the MES construction system for a smart factory according to the present invention using the File → Table button (530).

The file search → table button 540 is a component that searches for rows containing specific data in a CSV file and displays them as a table. Figure 12 is an example of a table for file search. Set the search period with two date selection windows 541, enter the text to be searched in the instrument window 542, and click the file search → table button 540. When a file is selected, among the rows of the selected file, the rows containing the search text written during the search period are displayed in a table format.

The table → file button 550 is a component that saves a table in csv file format, and performs the opposite function of the file → table button 530.

The data input window → file button 560 is a component that modifies or adds data to a file, and overwrite and continuation are provided as options. In the case of overwriting, the existing contents of the file are modified with the contents in the data input window, and in the case of continuation, the contents in the data input window are added to the end of the existing contents of the file. Figure 13 is an example of a data input window, where the date, region, and contents (data) of data 1 to data 10 in the items of the data input window can be overwritten or continued in the designated file.

The buttons that can perform special functions have been described above. The present invention facilitates data input and modification by using the master↔detail button 510 and the table↔input window button 520, and the file→table button ( 530), file search → table button (540), table → file button (550), and data input window → file button (560) to facilitate the manipulation of files where data is stored, allowing data between manufacturing and non-manufacturing departments Ensure delivery is easy and efficient.
