Figures 3 to 5 are drawings to explain the material warehousing, shipping and quantity management procedures, and
Figure 6 is a flowchart showing the driving process of the real-time material loading management system according to an embodiment of the present invention.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

1 is a diagram showing a real-time material loading management system according to an embodiment of the present invention.

As shown in FIG. 1, the real-time material loading management system 90 according to an embodiment of the present invention includes loading box devices 101 and 103, a projection device 110, a user terminal device 120, and a communication network 130. and part or all of the material management service device 140.

Here, “including part or all” means that some components such as the communication network 130 are omitted and the real-time material loading management system 90 is configured so that the projection device 110 and the material management service device 140 are directly connected to each other. (e.g. P2P) communication, or some or all of the components such as the material management service device 140 may be integrated into a network device (e.g. wireless exchange device, etc.) constituting the communication network 130. It means, etc., and is explained as including everything in order to facilitate a sufficient understanding of the invention.

The storage warehouse or storage box (or material box) 97 according to an embodiment of the present invention is a drawer-type multi-stage storage box and may be equipped with storage devices 101 and 103. That is, the storage box 97 includes a plurality of storage spaces for storing materials, and each storage space may be assigned identification information such as an identification number. Of course, it is possible to store the materials directly in each storage space, but in the embodiment of the present invention, a separate (storage) container 99 for transporting the materials is used to store the materials and store them in the storage space. and can be shipped. This container 99 may be equipped with an identification device 101 such as a QR code to identify the corresponding storage space, for example, in the form of an identification tag or sticker. Additionally, the container 99 may be further equipped with an electronic device including a communication module 103 that performs wireless communication such as RFID and a memory. For example, material information related to materials currently stored in the container 99 may be stored and managed in the memory. In particular, by storing information on the type (or type) of the material, a separate procedure (e.g., taking a photo, etc.) for determining the type of the material may be omitted when performing stock/delivery through the user terminal device 120.

The loading box 97 according to an embodiment of the present invention may have one side colored white or may include a white screen. Of course, the screen here may include white cloth or film. This screen is preferably configured to be visually recognizable to the worker when information related to the status of materials in the loading bin 97 is projected from the surrounding projection device 110. As will be explained later, the image projected from the projection device 110 in the form of a beam projector is basically a basic frame showing a multi-level storage space rather than simply projecting material status information, that is, it projects the image by dividing it into compartments. , information on the type and quantity of materials along with identification information is displayed on the inside of the relevant compartment, so that workers or managers can easily determine the status of materials.

The projection device 110, such as a beam projector, can actually simply project the processing screen provided by the material management service device 140 onto one side of the loading box 97, but as mentioned above, the storage space of the loading box 97 It may form a basic structure related to the division. Simply put, the front lens unit of the projection device 110 may be provided with a mesh-shaped filter that matches the structure of the storage space of the storage box 97. Of course, it is more desirable for the projection device 110 according to an embodiment of the present invention to be implemented as an image rather than having a mesh-shaped filter that matches the storage space.

The projection device 110 may also include a sensor. When it is determined through a sensor that there is a worker approaching the loading box 97, this is detected, and material status information is projected from the projection device 110 only for that time. Of course, these sensors may include various types of sensors, such as sound sensors that detect sound or light sensors that detect movement of people. Furthermore, when the projection device 110 is installed in a dark warehouse, the projection device 110 may be operated when the power switch is turned on.

The user terminal device 120 includes a mobile-based device carried by a worker or the like. It may include wearable devices such as smartphones or domestic S company's Galaxy*Gear. It may also include a kiosk-type touch screen device provided on one side of the production line. The user terminal device 120 can download and install a separate application (hereinafter referred to as an app) for using the service according to an embodiment of the present invention from the material management service device 140 or the App Store. For example, a worker or manager can run the app on the user terminal device 120 and then proceed with the procedure for receiving materials into the container 99 or proceed with the shipping procedure when shipping materials from the container 99. You can also check the material status periodically by accessing the material management service device 140.

When materials are received, the user terminal device 120 photographs the identification device 101, such as the QR code, of the basket of the materials, that is, the container 99. In this process, you can also take pictures of the materials and enter the quantity. In addition, at the time of shipment, the worker checks the list of materials needed by the worker through the user terminal device 120 and enters the list into the material management service device 140 through a web page developed using the QR code of the work order, etc. You can ensure that the material status is managed by performing the above operation upon or after shipping the material. The process of stocking and shipping materials using the user terminal device 120 may be performed similarly.

Material loading and unloading operations using the user terminal device 120 can be performed through voice recognition, etc. Due to the nature of the work, the shoe industry may require a lot of use of hands, and to facilitate the work, the input and output of materials can be performed through voice recognition. For example, if you wear a wearable device on your wrist, you can reduce the hassle of work by commanding all actions through voice recognition. Alternatively, the worker can wear a headphone-type microphone and perform a voice recognition operation to perform the loading and unloading of materials.

The communication network 130 includes both wired and wireless communication networks. For example, a wired or wireless Internet network may be used or linked as the communication network 130. Here, the wired network includes Internet networks such as cable networks and public switched telephone networks (PSTN), and the wireless communication network includes CDMA, WCDMA, GSM, EPC (Evolved Packet Core), LTE (Long Term Evolution), and Wibro networks. It means including. Of course, the communication network 130 according to an embodiment of the present invention is not limited to this, and can be used as an access network for a next-generation mobile communication system, for example, a cloud computing network in a cloud computing environment, a 5G network, etc. For example, if the communication network 130 is a wired communication network, the access point within the communication network 130 can connect to the telephone company's exchange office, etc., but if it is a wireless communication network, it can connect to the SGSN or GGSN (Gateway GPRS Support Node) operated by the communication company to receive data. Data can be processed by connecting to various repeaters such as BTS (Base Station Transmission), NodeB, and e-NodeB.

Communication network 130 may include an access point. The access point here includes small base stations such as femto or pico base stations that are often installed in buildings. Here, femto or pico base stations are classified according to the maximum number of projection devices 110 or user terminal devices 120 that can be connected in the classification of small base stations. Of course, the access point may include a short-distance communication module for performing short-distance communication such as Zigbee and Wi-Fi with the projection device 110 or the user terminal device 120. Access points can use TCP/IP or RTSP (Real-Time Streaming Protocol) for wireless communication. Here, in addition to Wi-Fi, short-range communication can be performed using various standards such as Bluetooth, Zigbee, infrared, radio frequency (RF) such as Ultra High Frequency (UHF) and Very High Frequency (VHF), and ultra-wideband communication (UWB). Accordingly, the access point can extract the location of the data packet, designate the best communication path for the extracted location, and forward the data packet to the next device, such as the material handling service device 140, along the designated communication path. Access points can share multiple lines in a typical network environment and include, for example, routers, repeaters, and repeaters.

The material management service device 140 manages in real time which materials are received and shipped from each storage space of the loading box 97, that is, the multi-level loading box. For example, the material management service device 140 divides each compartment of the storage space in a matrix form, builds a system, for example, programmatically, matches identification information for each compartment, and loads it based on the identification information (97 ) Manage the real-time status of materials entering and leaving the storage space. This system construction data can be systematically classified and managed in the DB 140a of FIG. 1. For example, when information related to the input and output of materials in each storage space is input from the user terminal device 120, the DB 140a is created based on this. Search and update related information.

In addition, the material management service device 140 transmits data related to the real-time material status to the projection device 110 so that the projection device 110 can project the real-time material status related to the materials in the loading box 97. For example, when there is a data transmission request from the projection device 110, the material management service device 140 transmits material status information in the loading box 97 that changes in real time based on the time, for example, when workers leave work, etc. In this case, the related operation can be stopped. That is, it enters an idle state. As mentioned above, in the idle state, various situations occurring around the loading box 97 can be detected and the operation of projecting material status information based on this can be resumed.

The material management service device 140 can form and transmit separate material status information in a data format for implementing the embodiment of the present invention with the projection device 110, but separately, it can be used on a PC-based computer or a mobile-based mobile device. If necessary, the device can connect to the material management service device 140 and perform procedures such as quantity management through the screen. Of course, when a PC-based computer such as a desktop computer or laptop computer is connected, the material management service device 140 provides services by executing a program according to an embodiment of the present invention produced on a web basis, and smart When a mobile-based mobile device such as a phone connects, a program created based on an app is run to provide services.

Above all, the material management service device 140 according to an embodiment of the present invention provides information such as a photographed image of the material being received in the container 99 or a QR code of the basket, that is, the container 99, from the user terminal device 120. Code information is captured and material receipt or shipment is processed based on this. Storage space can be identified through QR code recognition, and by taking an image of the material, the image can be analyzed to determine the type of material. In an embodiment of the present invention, a template-based image comparison operation can be performed for the recognition of such materials, and in this process, operations such as artificial intelligence (AI) deep learning can be used to increase the accuracy of the recognition operation of objects, that is, material classification. You can. For example, if it is difficult to recognize a material through image analysis, a message can be sent to the worker who requested receipt to ask whether the recognized material is correct. Through these operations, the accuracy of material recognition and classification operations can be increased. In this process, through the user terminal device 120, the worker can also input quantity information about the quantity of materials to be received and shipped. However, if the service is performed by taking images, the quantity can also be automatically determined through the image analysis results. This allows automatic calculation of the quantity.

As a result of the above configuration, the embodiment of the present invention makes it possible to manage materials that are entered and managed in the storage box 97 through a projection device 110 such as a beam projector, so in the case of shoe uppers, dozens of pieces of cutting material can be sewn. You will be able to easily check the status of materials while performing assembly processes such as gluing. In this regard, it is desirable to display related information in a location where workers can easily identify the material status that changes in real time, and in the embodiment of the present invention, one side is shown on the premise that the loading box 97 of FIG. 1 is in such a location. Although it is described as being used as a screen, it may also be possible to project it onto the wall or ceiling of the space where the production process takes place.

Figure 2 is a block diagram illustrating the detailed structure of the material management service device of Figure 1.

As shown in Figure 2, the material management service device 140 according to an embodiment of the present invention is a part or part of the communication interface unit 200, the control unit 210, the material warehouse management unit 220 and the storage unit 230. includes everything.

Here, “including part or all” means that the material management service device 140 is configured by omitting some components such as the storage unit 230, or that components such as the material warehouse management unit 220 are configured by the control unit 210. ), which means that it can be configured by being integrated with other components such as ), and is explained as being all-inclusive in order to facilitate a sufficient understanding of the invention.

The communication interface unit 200 communicates with the projection device 110 and the user terminal device 120 via the communication network 130 of FIG. 1, respectively. The communication interface unit 200 receives material information related to the arrival and departure of materials in the storage box 97 provided from the user terminal device 120, for example, provided according to the execution of an app, and transmits it to the control unit 210. For example, when there is an image taken for receiving materials from the user terminal device 120, more precisely, after recognizing the identification device 101 such as a QR code attached to the container 99 in a specific storage space, the material is captured. Material receipt can be requested through image taking, etc., and the communication interface unit 200 receives this and transmits it to the control unit 210.

In addition, even when materials are shipped from the container 99 in a specific storage space, the QR code is recognized to notify which storage space the materials are shipped from, and a photographing operation of the materials can be performed. For example, when you run the app and select a button such as stocking request or shipment request, after the operation to recognize the QR code, you may be guided to take a photo of the material once the QR code is recognized. After that, An operation may be performed to input quantity information. However, since the quantity information can be generated automatically through image analysis when the material is photographed, the embodiment of the present invention will not be particularly limited thereto.

Furthermore, the communication interface unit 200 provides the real-time material status of the loading box 97 through the user terminal device 120, that is, status information or status data related to the current status, to the projection device 110, and provides the real-time material status of the loading box 97 through the user terminal device 120. It should be projected on one side or on the wall of the production plant. Accordingly, workers can easily visually check the real-time status of changes in materials while performing work, which allows them to proceed with work more easily.

Additionally, the communication interface unit 200 may receive sensing information from the projection device 110. Through this, it is possible to determine whether real-time material status information is provided. For example, not only after workers' commuting hours, but also during meal times, the provision of information can be temporarily suspended based on surrounding situation information and then transmitted again.

The control unit 210 is responsible for the overall control operation of the communication interface unit 200, material warehouse management unit 220, and storage unit 230 of FIG. 2. The control unit 210 may perform an operation to update the DB 140a of FIG. 1 in real time based on material input and output information provided from the user terminal device 120 through the communication interface unit 200. Of course, such an update operation may be performed at the request of the material warehouse management department 220.

In addition, the control unit 210 controls the communication interface unit 200 at the request of the material warehouse management unit 220 to provide related data so that workers can easily check information on the material status of the loading bin 99, which changes in real time. The communication interface unit 200 is controlled to transmit to the projection device 110.

The material warehouse management unit 220 performs operations for material management according to an embodiment of the present invention. The material warehouse management unit 220 is connected to the user terminal device 120 to analyze the status of materials entering and leaving the loading box 97, and provides identification information of the storage space where the materials are stored and shipped, provided by the user terminal device 120. Perform operations to record the quantity of materials being used and materials being received and shipped.

In this process, the material warehouse management unit 220 recognizes identification information such as a QR code provided from the user terminal device 120, extracts objects related to the material from the received captured image, and extracts the extracted object image from the preset image. An operation can be performed to determine what kind of material it is by comparing it with the template image. If it is difficult to determine the recognition result, the user terminal device 120 may be notified to additionally confirm the material, but the recognition process may be performed through deep learning of artificial intelligence. However, in an embodiment of the present invention, it may be desirable to ask whether the result recognized by the user terminal device 120 is correct in order to increase the accuracy of material status management.

The material warehouse management unit 220 updates the data stored in the DB 140a in real time based on the information provided from the user terminal device 120, generates real-time material status data based on this, and sends it to the projection device 110. can be provided. Of course, since the projection device 110 simply projects an image according to the data transmitted from the material warehouse management unit 220, the material warehouse management unit 220 looks into the internal structure of the loading box 97 and displays the image in the form of Can be implemented on one side of the loading box (97). For example, the storage space is displayed as an image in the form of a partition, images related to materials are displayed within each storage space, identification information is displayed in the storage space, and information related to the quantity of materials is displayed in one space of the storage space image. can be displayed. We will discuss this in more detail later.

In addition, the material warehouse management department 220 provides related service videos when a worker or material warehouse manager accesses the service to check the material status through his or her computer, smartphone, tablet PC, wearable device, etc. Computers can provide web-based service screens, and mobile devices can provide service screens based on apps. The screen provided at this time may not be significantly different from the screen provided on one side of the loading box 97 through the projection device 110. However, it may be possible to further check the history of materials being received and shipped through the user terminal device 120. In other words, the image provided by the projection device 110 only needs to provide workers with information on the real-time status of materials necessary for work, but managers, etc. need to comprehensively manage materials for each day's work, so the projection device 110 ) can be viewed as part of the image that can be viewed through the user terminal device 120.

The storage unit 230 can temporarily store various information or data processed under the control of the control unit 210 and then output them upon request from the control unit 210. Since information and data are terms that are used interchangeably in practice, we will not specifically limit the concept of such terms. Typically, the storage unit 230 can store template images related to materials handled by workers, and through this, the material warehouse management unit 220 can recognize the materials through the analysis results of the images.

In addition to the above, the material management service device 140 of FIG. 2 can perform various operations, and other details have been sufficiently explained previously, so these will be replaced.

Meanwhile, as another embodiment of the present invention, the control unit 210 may include a CPU and memory, and may be formed as a single chip. The CPU includes a control circuit, an arithmetic unit (ALU), an instruction interpretation unit, and a registry, and the memory may include RAM. The control circuit performs control operations, the operation unit performs operations on binary bit information, and the command interpretation unit includes an interpreter or compiler, which can convert high-level language into machine language and machine language into high-level language. , the registry may be involved in software data storage. According to the above configuration, for example, at the beginning of the operation of the material management service device 140 of FIG. 1, the program stored in the material warehouse management unit 220 is copied, loaded into memory, that is, RAM, and then executed to perform data operation. Processing speed can be quickly increased.

Figures 3 to 5 are diagrams for explaining material warehousing, shipping, and quantity management procedures.

Figure 3 shows the quantity management procedure. When accessing the material management service device 140 through a mobile-based user terminal device 120 such as a smartphone, the current material status can be checked at any time. In addition, during work, the material status of the loading box 97 is displayed on the surface of the loading box 97 through a projection device 110 such as a beam projector. Through this, workers can easily determine the changing status of materials in the loading box 97 at a glance during work. 3, it can be seen that the screen displayed on the surface of the loading box 97 matches the configuration or shape of the screen displayed on the screen of the user terminal device 120, which is consistent with the material management service device 140. This is because the video in that format is produced and provided.

In summary, the worker requests the status through the developed material status web page, the projector, that is, the projection device 110, projects the photo and quantity of each material registered in the entire loading box onto the surface of each loading box, and the worker checks the actual material status. Check. The load and quantity of the loading box (97) are managed on the PC, projected onto the loading box (97) using a beam projector, and the type and quantity of materials are displayed on the surface of the loading box. When the worker selects the required materials with a mobile device, the material arrangement is displayed on the projector. It can be shipped by marking it with . Using a projector, the type and quantity of materials that change from time to time are investigated in real time, and when the worker selects the required material using a mobile device, it is displayed using a projector. After shipment, the quantity is adjusted when shipment is confirmed on the mobile device.

Figure 4 is a diagram for explaining the process of receiving materials into the loading box 97. The user terminal device 120 takes out the container 99 provided in a specific storage space within the storage box 97 and stores the materials. To this end, the user terminal device 120 can photograph the QR code of the incoming material basket and, of course, run the app in the process, and if necessary, the operation of photographing the actual product can continue. When photography occurs, the quantity of incoming material can be determined through image analysis, but the quantity can also be entered by the operator. Once these operations are completed, the worker presses the stocking request button to stock the materials. Alternatively, since the identification information is recognized, the storage space on the screen of the user terminal device 120 can be recognized through this and the operator can be recognized through color conversion of the designated area.

Of course, the worker using the user terminal device 120 can select the storage space where he/she wants to store the materials, and through this process, the materials the worker wants to store can be stored in the corresponding space. Of course, this stocking status is stored and managed in the DB 140a of FIG. 1, and through this process, the material status that changes in real time can be provided to workers as an image through the projection device 110.

In summary, the warehousing procedure is to take a picture with a mobile device and input the quantity through the developed registration web page when the cutting material to be warehousing is prepared, and the material management service device 140, which is a management server (WMS), is used in the loading box 97. Empty space is searched and the location is displayed with a projector, and workers can put materials into the marked loading bin (97) and enter completion of receipt on the web page. When registering a material, take a picture of the material with a mobile device and select registration, and the management server (WMS) PC opens an empty loading box and displays it on a projector. After the material is received, the mobile device registers the location and quantity of the material upon confirmation, and then loads ( 97).

Figure 5 shows the process of materials being shipped from the loading box. The material shipping process in Figure 5 is not much different from the material receiving process in Figure 4.
