However, the spirit of the present invention is not limited to the presented embodiments, and those skilled in the art who understand the spirit of the present invention will be able to easily propose other regressive inventions or other embodiments included within the scope of the spirit of the present invention by adding, changing, deleting, etc. other components within the scope of the same spirit, but this will also be considered to be included within the scope of the spirit of the present invention.

In addition, the terms described below are terms established in consideration of their functions in the present invention, and as such, they may vary depending on the inventor's intention or custom, and therefore, their definitions should be made based on the contents throughout this specification, and if it is determined that a specific description of a known configuration or function related to the present invention in this specification may obscure the gist of the present invention, a detailed description thereof will be omitted.

Hereinafter, a logistics distribution efficiency improvement system based on a digital classification device according to the present invention will be described with reference to the drawings.

FIG. 1 is a diagram showing the overall configuration of a logistics distribution efficiency improvement system based on a digital classification device according to one embodiment of the present invention.

A logistics distribution efficiency improvement system (10) based on a digital sorting device according to one embodiment of the present invention may be configured to include a digital sorting device (100), a cell detection device (200), a logistics management server (300), a work information display device (400), a work terminal (500), and an administrator terminal (600), and each device may be connected to a network to communicate with each other.

The online network referred to in the present invention may be a core network integrated with a wired public network, a wireless mobile communication network, or a portable Internet, and may mean a worldwide open computer network structure that provides various services existing in the TCP/IP protocol and its upper layer, such as HTTP (Hyper Text Transfer Protocol), HTTPS (Hyper Text Transfer Protocol Secure), Telnet, FTP (File Transfer Protocol), DNS (Domain Name System), SMTP (Simple Mail Transfer Protocol), and may include a short-range wireless network including ZigBee, Bluetooth, WIFI, RFID, NFC, etc.

However, it is not limited to these examples and comprehensively refers to a data communication network that can transmit and receive data in various forms.

The server mentioned in the present invention can be constructed as a server that plays at least one of the roles of a web service server, a database server, a big data server, and an application server, for example, it can display a processed result on a web page through an online network or receive necessary input data through a web page, and here, the web page should be interpreted as including software for performing specific tasks such as web applications in addition to simple text, images, sounds, and videos, and can also be constructed to provide an interface with applications installed on desktops, laptops, smartphones, tablet PCs, PDAs, etc. In addition, the server can perform at least one of the functions of a web service server, a database server, a big data server, and an application server in one physical server, or it can be configured and operated by being configured as a plurality of physically separated servers. However, the present invention is not limited thereto, and the type of the server can be changed in various ways at a level obvious to a person skilled in the art.

The digital sorting device (100) is a device installed in a distribution space that distributes products to be shipped by shipping location. It communicates with a logistics management server (300), receives and displays information on products to be distributed, and can transmit distribution status information according to the worker's distribution of products.

There may be multiple containers in a work area to distribute picked products to each shipping location.

Additionally, structures such as shelves and racks that can accommodate multiple containers may be placed in the workplace, and the space that contains one container accommodated in the structure is called a cell.

Hereinafter, the structure is described as a rack.

At this time, one cell may include one container and a cell detection device (200), and each cell may be distinguished by a cell identification code.

A container can be a shipping box, basket, storage box, etc. that can hold goods.

However, it is not limited to this and can be provided in various forms of containers.

A digital sorting device (100) can be attached to a structure and correspond to a plurality of cells, and information on the shipping location of each cell, order number, and the number of products to be distributed to the corresponding cell can be displayed.

Since at least one product can be distributed to each cell, the worker scans the product to be distributed through the work terminal (500) to request the start of the distribution work, and the logistics management server (300) that receives the request can instruct the digital sorting device (100) to display the number of products to be distributed to each cell.

Accordingly, the worker can check the number displayed on the digital sorting device (100) and distribute the corresponding product to multiple cells.

The cell detection device (200) can be installed in a cell in a rack, and one cell detection device (200) can be installed for each cell.

The cell detection device (200) measures the change in weight of the container to recognize whether it contains a product and transmits the information to the digital classification device (100).

For this purpose, the cell detection device (200) can perform a communication connection with the digital classification device (100).

More specifically, when the cell detection device (200) receives a product insertion detection request from the digital sorting device (100), it periodically measures the change in weight of the container and transmits product insertion detection information to the digital sorting device (100).

At this time, product insertion detection information may include detection status (normal, abnormal), weight before detection, and detected weight.

The digital sorting device (100) receives product input detection information from the cell detection device (200) and changes and displays the number of products to be distributed on the display unit.

This allows workers to reduce work time and increase efficiency by eliminating the need for separate input work to complete distribution work after placing products in the corresponding cells.

The logistics management server (300) receives delivery information of products ordered by a customer, distributes products to multiple cells according to the delivery information, transmits work details to a digital sorting device (100), and receives distribution work status information from the digital sorting device (100) to store the work information.

In addition, the distribution work status is transmitted periodically or in real time to the work information display device (400) so that the work information display device (400) can display the information received.

In addition, the digital sorting device (100) can be instructed to provide product information, distribution work details assigned to workers, distribution work progress status, etc. at the request of the application installed in the work terminal (500), and to display the product distribution work assigned to workers at the request of the work terminal (500).

The work information display device (400) can receive real-time work status/status and statistical information on the distribution work status from the logistics management server (300) and display them on the screen.

The work information display device (400) may include a communication unit that receives work progress rate and work status information from the logistics management server (300), a memory that stores a program and data for control, a display unit that displays the received work status information on a display device, and a control unit that controls the operation of each unit.

For example, the work information display device (400) may be configured with an LCD display connected to a PC, laptop, or desktop.

At this time, the control device such as a connected PC, laptop, or desktop may support at least one of wired and wireless communication to receive work status information to be displayed on the LCD display.

As another example, the work information display device (400) may be a device including a CPU/MCU, memory, and network interface inside the LCD display hardware device.

The work terminal (500) can retrieve information necessary for the worker to perform distribution work through the installed application.

For this purpose, the work terminal (500) may be in the form of a PDA equipped with a scanner function.

Additionally, a network interface may be provided to enable wireless network communication.

More specifically, through the application installed in the work terminal (500), the worker can transmit worker information, check product information, check distribution work assigned to the worker, request distribution work start, check distribution work status, etc.

In addition, the work terminal (500) may be equipped with a scanner function, through which a barcode, QR code, etc. attached to a product can be scanned to obtain product information or request the logistics management server (300) to start product distribution work.

For example, when a worker enters his/her identification code or scans a barcode or other worker identification code through a work terminal (500), the work terminal (500) transmits the scanned information to the logistics management server (300), and the logistics management server (300) verifies the worker information and transmits the distribution task information assigned to the worker to the work terminal (500).

At this time, the worker can check the assigned distribution work information displayed on the work terminal (500) and request the start of the distribution work.

Here, requesting the start of a distribution task means indicating the number of cells and products to which products should be distributed to the digital sorting device (100) so that the distribution task assigned to the worker can be distributed to a container located in a specific cell.

The management terminal (600) should be interpreted as including various communication means such as a desktop, tablet, netbook, PDA (personal digital assistant), PMP (portable multimedia player), smartphone, wearable smart device, etc., and can execute various functions provided by the logistics management server (300) through web-based or separate software/application, etc.

More specifically, the administrator can set up the device settings and communication connection of the digital classification device (100), cell detection device (200), and work information display device (400) through the application of the administrator terminal (600).

In addition, the manager can monitor the progress of overall logistics management work in real time through the application of the manager terminal (600), define cells, assign an identification code to each cell, assign a cell detection device (200) to one cell, and perform tasks of mapping multiple cells to a digital classification device (100).

Additionally, the administrator can register worker information and upload ordered shipment information through the application of the administrator terminal (600).

Meanwhile, the manager can monitor all devices installed in the workplace through the manager terminal (600), check the status, and identify errors and failures.

FIG. 2 is a configuration diagram of a digital sorting device (100) in a logistics distribution efficiency improvement system based on a digital sorting device according to one embodiment of the present invention, and FIG. 3 is a screen configuration diagram of a digital sorting device (100) in a logistics distribution efficiency improvement system based on a digital sorting device according to one embodiment of the present invention.

The digital classification device (100) will be described in detail with reference to FIGS. 2 and 3.

A digital classification device (100) may be composed of a hardware device having a display module, a communication module, a memory, and a control unit such as an MCU or CPU, and a software program stored and operated in the memory.

Additionally, the display module can support a touch interface.

A digital classification device (100) may include a communication unit (110), a touch unit (120), a control unit (130), and a display unit (140).

The communication unit (110) can transmit and receive data through a network interface capable of at least one of wired and wireless communication.

At this time, the communication unit (110) can transmit and receive data with the cell detection device (200) and the logistics management server (300) by applying predefined linkage standards.

For example, the communication method may be based on short-range wireless communication such as WIFI, Bluetooth, Zigbee, or RFID.

As another example, the communication connection may be wired depending on the environment of the workplace.

However, without limitation to this, various communication technologies that can be derived by ordinary technicians can be applied.

Meanwhile, after the cell detection device (200) and the digital sorting device (100) are placed in a specific cell of a rack installed in a work space, the digital sorting device (100) and the cell detection device (200) can perform a communication connection to the logistics management server (300).

The logistics management server (300) transmits communication connection information of the set digital classification device (100) and cell detection device (200), and a communication connection is established between the digital classification device (100) and cell detection device (200) based on the received information.

The communication unit (110) receives data from the digital classification device (100) and the cell detection device (200), transmits it to the control unit (130), and transmits data requested by the control unit (130) through a communication channel.

The touch unit (120) detects a touch event on the screen of the digital classification device (100), analyzes the contents of the event, and transmits it to the control unit (130).

For example, the screen of the digital classification device (100) is configured as an LCD touch panel, and can receive and process user input through a touch interface.

The touch interface can find the location (coordinates) where a touch event occurs according to the screen configuration of the digital classification device (100) and transmit an event corresponding to the screen configuration to the control unit (130).

That is, the UI element corresponding to the location where the touch occurred on the current screen is checked and the event processing set in the UI is performed.

The control unit (130) controls the operation of each part of the digital classification device (100) and performs the operation function of the digital classification device (100).

More specifically, data received from the communication unit (110) can be processed and transmitted to the display unit (140) for display on the screen.

For example, when the communication unit (110) receives the order number and shipping information to be displayed in each cell and product information (product weight, product quantity, product ID, etc.) to be input into each cell from the logistics management server (100), the order number, shipping information, and product quantity to be input can be displayed on the screen through the display unit (140).

In addition, when the communication unit (110) receives product insertion detection information from the cell detection device (200), it can analyze the product insertion detection information, determine whether product insertion into the cell is complete, and instruct the logistics management server (300) to transmit the corresponding information.

Product insertion detection information may include detection status (normal, abnormal), weight before detection, and detected weight.

If the detection status of product insertion detection information is normal, the number of products inserted can be calculated using the detected weight to determine whether product insertion into the cell is complete.

If the detection status of product input detection information is abnormal, it can be displayed on the screen through the display unit (140) in a pre-determined manner.

For example, a predefined method could be to display the color of a cell in a predetermined color, print text, or set the screen of that cell to blink.

Meanwhile, the control unit (130) can receive an event from the touch unit (120) and perform an action corresponding thereto.

For example, when a worker adjusts the quantity of goods or a touch event occurs for the completion of goods input processing, the corresponding information can be transmitted to the logistics management server (300) through the communication unit (110).

At this time, the LCD screen of the digital sorting device (100) can be set to detect a touch event for an area where the product quantity is displayed.

Meanwhile, the digital sorting device (100) can determine whether a product has been put in through the worker's touch on the screen in addition to receiving information on whether a product has been put in from the cell detection device (200).

That is, a function that can recognize whether a product has been inserted can be provided through input from a worker even without a cell detection device (200).

In addition, by comparing the product input information received from the cell detection device (200) with the touch event information generated by the worker touching the screen, it is possible to determine whether the final product has been input.

Accordingly, a logistics distribution efficiency system (10) can be configured by selectively using a cell detection device (200) depending on the environment of the workplace, and there is an advantage in that the accuracy of product distribution can be increased by comparing the information transmitted from the cell detection device (200) with the worker's touch input information.

The display unit (140) constitutes the screen of the digital classification device (100) and can display data on the screen according to the control instructions of the control unit (130).

Referring to Fig. 3, the screen configuration of the digital classification device (100) according to the work status is described.

The initial screen may display a cell identification code (cell number). This means that there is no assigned task. (See No. 1 in Figure 3)

The number of cells that can be displayed on the digital classification device (100) can be determined in advance depending on the size of the digital classification device (100).

Additionally, the maximum number of cells that can be displayed on the screen is determined in advance, and the number of cells displayed on the screen can be set within the maximum number according to the administrator's settings.

Accordingly, the number of cells can be adjusted according to the size of the container that the rack can accommodate, and this can be reflected on the screen of the digital sorting device (100).

For example, a cell displayed on the screen of a digital classification device (100) may basically be composed of two rows and n columns.

This is to enable the digital sorting device (100) to be placed between the shelves of the rack so that the upper/lower cells and the cell information displayed on the digital sorting device (100) can be intuitively matched and confirmed.

However, without being limited thereto, cells displayed on a digital classification device (100) may be displayed in a table format of m*n (m is the number of rows, n is the number of columns) depending on the structure of the rack.

When work is started according to the work instructions of the administrator terminal (600), each cell of the screen of the digital classification device (100) can display the assigned order number. (See No. 2 of FIG. 3)

Afterwards, when the worker checks the work assigned to him/her and scans the product to be distributed through the work terminal (500), the logistics management server (300) transmits the number of products to be assigned to each cell, and the digital sorting device (100) that receives this displays the number of products corresponding to each cell on the screen. (Refer to No. 3 of FIG. 3)

Product distribution tasks can be assigned to workers on a product-by-product basis.

That is, one product distribution task can mean distributing the same product to multiple cells.

When a worker inserts a product, the cell detection device (200) recognizes the product insertion and transmits it to the digital sorting device (100).

The digital sorting device (100) that receives this can display the number of products to be placed by the next worker on the screen. (See No. 5 of Fig. 3)

At this time, cells can be displayed in different colors to distinguish the target cells for the worker's distribution work.

For example, the first worker's work cells might be colored green, the second worker's work cells might be colored orange, etc.

Therefore, multiple workers can distribute different products (types of products) simultaneously, which can increase work efficiency.

Meanwhile, in a distribution task, it can be indicated to the worker that it is the last cell of the task. (See No. 4 in Fig. 3)

For example, if it is the last cell, the cell may blink on the digital display device (100).

As another example, a cell may be displayed in a specific color.

However, it is not limited to this and can be expressed in various ways that can be derived by a person skilled in the art.

When all ordered items are placed in the cell, the work can be marked as complete. (See No. 6 in Figure 3)

For example, cells that have completed work might be highlighted in red, and information about the order number and shipping information might be displayed.

Additionally, a phrase or symbol indicating completion may be displayed.

Additionally, the total quantity of goods ordered may be displayed.

The digital sorting device (100) can transmit information on cells in which work has been completed to the logistics management server (300) to convey the work status.

Meanwhile, the functions of the communication unit (110), touch unit (120), control unit (130), and display unit (140) of the digital classification device (100) described above can be implemented and operated on the worker terminal (500).

More specifically, the worker terminal (500) may be a portable terminal device such as a PDA, a mobile phone, a tablet, or a laptop, and the above components of the digital classification device (100) may be configured and operated in the form of an application (software) on the worker terminal (500).

An application (software) installed on a worker terminal (500) and performing the function of a digital sorting device (100) can replace the function of a digital sorting device (100) installed in a rack.

That is, instead of a digital sorting device (100) installed on a rack, a worker uses a worker terminal (500) to check product information to be input into each cell and perform distribution work, and when the product input work into the corresponding cell is completed, the worker terminal (100) can touch the corresponding cell through a screen displayed in the same manner as the digital sorting device (100) to notify completion of product input.

A cell detection device (200) is installed in each cell of the rack to detect whether a product has been placed in a container accommodated in the corresponding cell and transmit the result to a digital sorting device (100).

The cell detection device (200) may be composed of a hardware device having a sensor module that recognizes changes in weight, a communication module, a memory, and a control unit such as an MCU or CPU, and a software program that is stored and operated in the memory.

FIG. 4 is an exemplary configuration diagram of a digital sorting device (100) and a cell detection device (200) in a logistics distribution efficiency improvement system based on a digital sorting device according to one embodiment of the present invention.

The operation of the cell detection device (200) is described with reference to Fig. 4.

The cell detection device (200) can be installed on a shelf of a rack (700) and can be installed at each location where a container is received on the shelf.

At this time, the cell detection device (200) can be detached or installed built into the rack (700).

Meanwhile, the cell detection device (200) can correspond to each cell, and a plurality of cell detection devices (200) can correspond to one digital classification device (100) and communicate with each other.

When the cell detection device (200) is in operation, it can communicate with the logistics management server (300) and receive information on the digital classification device (100) to be connected.

Based on the received information, the cell detection device (200) can establish a communication connection with the mapped digital classification device (100).

Afterwards, when a container is installed in each cell and distribution work begins, the cell detection device (200) detects a change in weight and transmits the corresponding detection information to the digital sorting device (100).

This can improve work efficiency by reducing the hassle of having to manually check whether product input is complete by touching the digital sorting device (100) or pressing an input button every time a worker inputs a product into a container.

The cell detection device (200) can receive and detect weight information to be detected from the digital sorting device (100) to detect product input.

In addition, if a change in weight other than the weight to be detected is detected, this is transmitted to the digital sorting device (100), and the digital sorting device (100) can display the corresponding information on the screen to inform the worker.

Additionally, the number of products can be calculated through the detected weight change and transmitted to the digital sorting device (100).

FIG. 5 is a configuration diagram of a logistics management server (300) in a logistics distribution efficiency improvement system based on a digital classification device according to one embodiment of the present invention.

The logistics management server (300) may be equipped with a linkage unit (310), a device unit (320), a work unit (330), a service provision unit (340), and a DB (350).

The linkage unit (310) may include a device linkage unit (311) that performs data transmission and reception with a digital classification device (100), a cell detection device (200), and a work information display device (400), and a shipment information linkage unit (312) that collects shipment management information.

The device linkage unit (311) performs communication connections with at least one digital classification device (100), multiple cell detection devices (200), and at least one task display device (400).

At this time, the device linkage unit (311) transmits the corresponding mapping information and connection information to the digital classification device (100) and cell detection device (200) that are connected to each other according to the mapping information of the pre-configured digital classification device (100) and cell detection device (200).

The digital classification device (100) and cell detection device (200) that received the transmitted connection target can proceed with communication connection between each other based on the matching information.

The shipment information linkage unit (312) can receive order information and shipment information for product distribution by shipment location.

For example, the shipment information linkage unit (312) can collect/store shipment information by linking with a server or system that manages order information and shipment information according to defined linkage standards.

Additionally, it provides an interface for uploading shipment information in file form, enabling collection of shipment information from non-linked servers or systems.

The device unit (320) may include a setting unit (321) that registers/manages information on a digital classification device (100), a cell detection device (200), and a work information display device (400), and performs settings for each device, and a monitoring unit (322) that monitors the connection status of each device.

For example, the setting unit (321) can register/manage each device type, device ID, and device connection information.

In addition, the setting unit (321) can store/manage mapping information by mapping multiple cells and cell detection devices (200) installed in the cells according to the placement location of the digital classification device (100).

At this time, the mapping information may include cell identification code, cell order information, cell detection device (200) ID, etc.

The administrator can search for registered devices through the user interface provided by the administrator terminal (600) and map between the devices, and the setting unit (321) receives the mapping information entered by the administrator terminal (600) and stores the mapping information between the devices.

In addition, the setting unit (321) can set the screen display configuration of the task display device (400) based on the screen configuration information configured by the administrator through the administrator terminal (600).

For example, the screen display configuration may include the total number of orders, the number of orders distributed, the progress, the total number of items, the number of items distributed, etc.

The monitoring unit (322) can monitor the data transmission and reception status of the registered and communication-connected digital classification device (100), cell detection device (200), and work information display device (400).

For example, by transmitting data to the logistics management server (300) to check the connection status at regular intervals, the digital sorting device (100), cell detection device (200), and work information display device (400) can confirm that the connection status is normal.

However, it is not limited to this and the connection status between devices can be checked by applying various protocols and methods.

The work unit (330) can schedule product distribution work and assign it to workers based on order information and shipment information.

The work unit (330) may include a worker management unit (331), a distribution unit (332), a work processing unit (333), a statistics unit (334), an invoice generation unit (335), and a work monitoring unit (336).

The worker management department (331) can register/manage worker information.

At this time, worker information may include worker ID, name, product part in charge, work schedule (day/night), etc.

Additionally, worker information can be stored in DB (350).

The distribution unit (332) can create distribution tasks, schedule, and create cell distribution information according to the product type, number of products, shipping location, and number of workers.

For example, tasks can be created and scheduled by considering the number of order information or shipping information and the number and type of ordered products, and by determining the order of the tasks.

In addition, for the generated work, distribution work can be performed to each cell by considering the size of the cell according to the product type and order quantity of the shipping location.

This is because the size, weight, and shape differ depending on the product type, and the size of the container varies depending on the number of products ordered.

When configuring multiple racks, the cell sizes can be configured to be different, and the product groups and quantities that can be accommodated in each cell can be defined in advance, and distribution work assignments can be performed based on this.

The distributed allocation work history can be stored and managed in DB (350).

The work processing unit (333) manages the status of the distribution work and controls the work according to the status of the work.

More specifically, upon request from the work terminal (500), the DB (350) is searched and the distribution work information assigned to the corresponding worker is transmitted to the digital classification device (100).

For example, when an administrator requests to start a task through an administrator terminal (600), the task processing unit (333) searches for task schedule information in the DB (350) and transmits an order number to the cell.

Afterwards, when the worker scans the product to be distributed through the work terminal (500) and transmits the product information, the work processing unit (333) transmits the quantity of the scanned product to be distributed to the order information currently placed in the cell.

In addition, the work processing unit (333) can receive the completion of input of products distributed to each cell from the digital classification device (100) and store the corresponding information in the DB (350).

At this time, the work processing unit (333) can manage the status of the distribution task to perform the distribution task as described above.

For example, the status of a distribution task can be defined as a task assignment status in which distribution task information is generated by the distribution unit (332) and assigned to a worker, a task start status in which order information/delivery information assigned to each cell of the digital sorting device (100) is displayed, a cell distribution task status in which a worker checks the distribution task assigned to him/herself, scans the product to be distributed, and displays the number of products to be input into each cell of the digital sorting device (100), a product input completion stage in which input of the corresponding product into each cell is completed, and a task completion status in which input of all products for the order number is completed.

The task processing unit (333) can perform operations according to the status of each task.

Additionally, each state can be managed in DB (350) along with work information.

The statistical department (334) can generate real-time distribution work status and statistical data to be displayed on the work information display device (400) and store them in the DB (350).

Real-time distribution task status may include total number of orders, number of completed distribution tasks, distribution task rate, total number of products, number of completed distribution tasks, etc.

Additionally, it can further include the number of real-time distributed tasks and completion rates per worker.

Additionally, the above information can be generated and managed as hourly, daily, monthly, and yearly statistics.

The invoice generation unit (335) can generate invoice information for a cell where distribution of goods has been completed and provide it upon request from a work terminal (500) or an administrator terminal (600).

Invoice information can be generated with an invoice template and the orderer information, shipper or recipient information, and ordered product information that must be recorded in the invoice so that it can be printed according to predefined invoice specifications.

The work monitoring unit (336) can periodically monitor the progress of distribution work and send notification messages to the work terminal (500) and the administrator terminal (600).

More specifically, the processing time for an unfinished distribution task can be checked and, if it exceeds a preset threshold time, a notification message can be sent to the corresponding manager terminal (600) and the task terminal (500) assigned to the task.

Additionally, notification messages can be sent to notify all workers of error situations in specific devices or cell distribution operations.

The service provider (340) can provide assigned distribution work information, progress status, statistical data, worker information, distribution work schedule, device information for registered digital sorting device (100)/cell detection device (200)/work information display device (400), and configuration information inquiry/registration service, etc., at the request of the administrator terminal (600) or work terminal (500).

For example, the service provider (340) provides the necessary service information in response to a web request or a request from an application installed on an administrator terminal (600) or a work terminal (500), so that a worker or administrator can use the function provided by the logistics management server (300) from a remote location.

At the request of the management terminal (600), the logistics management server (300) can transmit order information and shipping location information assigned to each cell to the digital sorting device (100) for sorting work.

The digital sorting device (100) that receives this displays the order information and shipping information assigned to each cell on the screen, and the worker can check the displayed information to recognize that preparation for distribution work is complete (S640).

The worker checks the distribution work information assigned to him/her through the work terminal (500) and scans the product to be distributed.

At this time, the work terminal (500) can transmit scan information to the logistics management server (300) to request the start of distribution work for the corresponding product.

The logistics management server (300) can receive scan information, retrieve cell distribution information for the corresponding product, and transmit it to the digital classification device (100) (S650).

Upon receiving this, the digital sorting device (100) can display the number of products to be distributed to each cell on the screen (S660).

Additionally, detection of product insertion can be requested using a cell detection device (200).

At this time, the weight information of the product to be detected can be transmitted to the cell detection device (200).

Next, the worker checks the number of products displayed on the digital sorting device (100) and inserts the products.

When product insertion is detected, the cell detection device (200) can transmit the detection information to the digital classification device (100) (S670).

The digital classification device (100) that receives this can compare the number of products allocated to the corresponding cell with the number of products detected by the cell detection device (200) to determine whether product input is complete.

When a specific product is put into a cell, it can be transmitted to the logistics management server (300) (S680).

Next, when the logistics management server (100) receives information on the completion of product input into a specific cell, it can update distribution work status information (S690).

Thereafter, the work display device (400) periodically requests work status information from the logistics management server (100), receives the information, and displays it on the screen so that workers and managers can easily check the overall work status without a separate inquiry task.
