The processor (210) can control other components of the electronic device (110) in general and process a series of steps for performing an integrated management method of a barcode scanner (120) according to various embodiments of the present disclosure.

The processor (210) may have the ability to process data received from a barcode scanner (120) through a network (140) together with the running software, store such data in memory, and then retransmit the data through the network (140) as needed. The real-time data processing capability of the processor (210) and the storage function of the memory enable efficient data exchange through the network (140).

The processor (210) can process data received from the barcode scanner (120) and transmit it to the server (150) or communicate with the database of the server (150) to perform necessary tasks.

According to one embodiment of the present invention, the processor (210) may perform a function of processing data received from the barcode scanner (120). Accordingly, the processor (210) may transmit the data to the server (150) or communicate with a database located in the server (150) to perform a necessary task. Specifically, the processor (210) analyzes data input from the barcode scanner (120), converts it into an appropriate format, and then transmits it to the server (150). In addition, the processor (210) may access or update the database of the server (150) in real time through communication with the server (150), thereby supporting necessary tasks in various applications. In addition, the processor displays the information processed on the electronic device (110) so that the user can check it in real time.

The processor (210) can perform communication and management tasks with the barcode scanner (120) through an application (221) running on the electronic device (200). Specifically, the processor (210) performs a role in charge of organic communication and management tasks with the barcode scanner (120). The communication and management tasks of the processor (210) are realized through the application (221), which may mean a software program running on the electronic device (200).

The application (221) is linked to the processor (210) to collect status information of the barcode scanner (120), transmit control commands, and smoothly process data transmission and reception operations. The processor (210) transmits commands of the application (221) to the barcode scanner (120) to control the operation of the scanner, and can perform a function of interpreting and processing data received from the scanner. The electronic device (200) can configure a system that can effectively perform communication and management operations with the barcode scanner (120) through collaboration between the processor (210) and the application (221).

Specifically, the processor (210) can integrate the data collected from the barcode scanner (120) and analyze the data to obtain meaningful information necessary for logistics and inventory management. Specifically, the processor (210) can monitor inventory levels, product delivery, product recovery, and other logistics-important data in real time, and can perform efficient logistics and inventory management based on this.

The memory (220) can store various information (data). The information stored in the memory (220) is information acquired, processed, or used by at least one component of the electronic device (200), and may include software (e.g., commands, programs, etc.). For example, the memory (220) may store an operating system (OS), an application (221), etc. for performing basic operations and resource management functions of the electronic device (200). In the present disclosure, the commands or programs are software stored in the memory (220), and may include an operating system for controlling resources of the electronic device (200), an application programming interface (222), and/or middleware for providing various functions to the application so that the application (221) can utilize the resources of the electronic device (200). In one embodiment, the memory (220) may store commands that cause the processor (210) to perform operations when executed by the processor (210). For example, applications (221) are programs that users utilize to perform specific tasks, and these applications (221) can also be stored in memory (220). An application programming interface (222) acts as an intermediary to enable applications and an operating system to interact, and the application programming interface (222) can also be stored in memory (220).

The memory (220) may cooperate with the processor (210) in data storage and processing tasks to increase the overall efficiency and stability of the system. Specifically, the memory (220) may store data collected from the barcode scanner (120) and retrieve it when necessary. The memory (220) may permanently or temporarily store data so that the system can achieve management goals. The memory (220) may immediately store data input from the barcode scanner (120) and provide the data so that the processor or other system components can access it when necessary. Additionally, the memory (220) may store data that the processor (210) is working on. Specifically, the memory (220) may temporarily store data that the processor (210) is calculating to ensure the continuity of the task. For example, the processor (210) may continue the task without interruption by storing intermediate calculation results or necessary temporary data in the memory.

The memory (220) may include volatile and/or nonvolatile memory. The memory (220) may store at least a portion of information received from the database via the communication interface (230) and/or information transmitted to the database via the communication interface (230). In one embodiment, the memory (220) may replace the role of the database. The memory (220) may store information relating to logistics and instructions configured to be executed by the processor (210).

The communication interface (communication interface, 230) can perform wireless or wired communication between the electronic device (200) and a database or another electronic device (110). For example, the communication interface (230) can perform wireless communication according to a method such as eMBB (enhanced Mobile Broadband), URLLC (Ultra Reliable Low-Latency Communications), MMTC (Massive Machine Type Communications), LTE (Long-Term Evolution), LTE-A (LTE Advance), NR (New Radio), UMTS (Universal Mobile Telecommunications System), GSM (Global System for Mobile communications), CDMA (Code Division Multiple Access), WCDMA (Wideband CDMA), WiBro (Wireless Broadband), Wi-Fi (Wireless Fidelity), Bluetooth, BLE (Bluetooth Low Energy), NFC (Near Field Communication), GPS (Global Positioning System), or GNSS (Global Navigation Satellite System). For example, the communication interface (230) may perform wired communication according to a method such as Universal Serial Bus (USB), High Definition Multimedia Interface (HDMI), Recommended Standard-232 (RS-232), or Plain Old Telephone Service (POTS). In one embodiment, the electronic device (200) may be implemented by being integrated with another device. In this case, the communication interface (230) may function as a connection circuit or interface that connects the electronic device (200) and the other device.

Hereinafter, the operations described as being performed by the electronic device (110) in FIGS. 3 to 8a and 8b can be understood as being performed by the processor (210) of the electronic device (200) described in FIG. 2.

FIG. 3 is a flowchart illustrating a method according to one embodiment of the present disclosure. The flowchart consists of steps S310, S320, S330, S340, and S350.

The electronic device (110) can identify a barcode scanner (120) connected to the electronic device (110) (S310). With additional reference to FIG. 4, identifying a barcode scanner (120) connected to the electronic device (110) will be described in detail. FIG. 4 is a drawing showing a screen of an electronic device (110) related to device identification according to one embodiment of the present disclosure.

When the electronic device (110) is connected to a barcode scanner (120), it can identify the connected barcode scanner (120). The first screen (410) of FIG. 4 represents the main screen of the application. The first screen (410) may display various buttons that allow the user to perform actions necessary for logistics. Through the scanner setting button of the first screen (410), the user can select a device (e.g., a Bluetooth device) to be connected to the electronic device (110) or select a connected device.

The second screen (420) of Fig. 4 shows a pop-up interface for selecting a barcode scanner (120). The second screen (420) shows the process of a user selecting a device to be connected. A pop-up window is shown in the center of the second screen (420), and the electronic device (110) can identify the type of barcode scanner (120) to be connected according to user input.

Additionally or alternatively, the electronic device (110) can identify the barcode scanner (120) from the recognized barcode scanner (120) via an established connection (130), such as a specific protocol or interface. Specifically, unique identification information can be transmitted from the barcode scanner (120) recognized by the electronic device (110) to the electronic device (110). The electronic device (110) can identify the model, specifications, functions, etc. of the connected barcode scanner (120) based on this identification information. When the electronic device (110) is connected to the barcode scanner (120), it can proceed with the initial steps for executing subsequent tasks by identifying the device.

The electronic device (110) can determine a communication method for interacting with the identified barcode scanner (120) (S310). Specifically, the electronic device (110) can receive a signal transmitted from the barcode scanner (120). The signal can include information on the communication method of the barcode scanner (120). The electronic device (110) can analyze the received signal to identify a communication method supported by the barcode scanner (120). The identified communication method can be one of HID, BLE, and SPP. Specifically, HID is a protocol generally used to exchange data with input devices such as a keyboard and a mouse, and can be applied to communication with the barcode scanner (120). Additionally, BLE is a type of Bluetooth technology characterized by low power consumption, and can be used to connect the barcode scanner (120) and the electronic device (110) in a wireless environment. Additionally, SPP is a profile that mimics serial communication between Bluetooth devices and can be selected as one of the communication methods for data transmission between a barcode scanner (120) and an electronic device (110). The electronic device (110) can communicate data more effectively with the barcode scanner (120) by using various communication methods.

In one embodiment, the electronic device (110) may proceed with a connection corresponding to the determined communication method. For example, if the barcode scanner (120) supports Bluetooth communication, the electronic device (110) may attempt to connect to the barcode scanner (120) via the Bluetooth protocol. Similarly, if the barcode scanner (120) supports other connection methods such as Wi-Fi or NFC, the electronic device (110) may select a protocol appropriate for the connection method and establish a connection.

The electronic device (110) can determine whether a key input event has occurred from a barcode scanner (120) by an event listener as a receiver that processes key input events in response to a determination that the communication method is the first communication method (S320).

In an additional embodiment, the electronic device (110) may, in response to a determination that the communication method is a second communication method different from the first communication method, load an SDK corresponding to the barcode scanner (120) and receive data of a barcode scanned by the barcode scanner (120) through the loaded SDK.

Specifically, when the communication method is a second communication method different from the first communication method, for example, when the communication method supports SDK, a communication connection with the scanner is established using an SDK provided by a manufacturer or supplier of the barcode scanner (120). For example, the second communication method may be an SPP method. After loading the SDK, the electronic device (110) can receive barcode data scanned from the barcode scanner (120) through the SDK. Specifically, the SDK can provide a function that can interpret the data scanned by the barcode scanner (120) and transmit the same to a user application. Therefore, the electronic device (110) can successfully receive barcode data through the SDK and additionally process or store the data as needed.

The electronic device (110) can be easily connected to a barcode scanner through the SDK and can be provided with various functions. The SDK can be useful in that it can simplify the communication connection setup procedure and provide additional functions such as data interpretation and processing. Through this, the electronic device (110) can communicate with the barcode scanner (120) more efficiently.

The case where the communication method is the first communication method will be described in more detail with reference to FIG. 5. FIG. 5 is a flow chart showing a data processing process between a barcode scanner (120) and an electronic device (110) according to one embodiment of the present invention. FIG. 5 explains the tasks performed at each stage.

Specifically, the electronic device (110) may activate an event listener capable of detecting a key input event from a barcode scanner (120) when the selected communication method is the first communication method. For example, the first communication method may be an HID method, and the electronic device (110) may detect an event from a barcode scanner (120) that operates similarly to an HID keyboard. The event listener refers to an element that can monitor data input from the barcode scanner (120) in real time as a receiver that processes a key input event. Referring to FIG. 5, at the library level, the electronic device (110) may detect a key event from the barcode scanner (120) and convert it to a scan state. Listening to Key Events from Hardware Devices represents a step of detecting a key event from the barcode scanner (120). For example, listening to key events enables the electronic device (110) to receive a key input event occurring from the barcode scanner (120). Transform Key Event into Scan Status represents a step of transforming a detected key event into a scan state. For example, transforming a key event into a scan state enables the electronic device (110) to transform key input data into state information and pass it on to the next step.

In one embodiment, the electronic device (110) can determine whether a received signal is a normal barcode scan event. This determination can be made by comparing the data input from the barcode scanner (120) to a predetermined format or by checking that it matches a predefined key input pattern.

In one embodiment, the electronic device (110) may perform initial setup for data processing prior to receiving a series of information when the occurrence of an event is determined. The initial setup may include parsing of the barcode data, verification of data integrity, and, if necessary, additional post-processing operations.

In response to determining that a key input event has occurred, the electronic device (110) can receive the barcode scanned by the barcode scanner (120) as a series of key information (S330). Specifically, the barcode scanner (120) can convert the barcode data read by the barcode scanner (120) into a series of key information through decoding and transmit it to the electronic device (110). The electronic device (110) can receive the data read by the barcode scanner (120) through a communication interface between the barcode scanner (120) and the electronic device (110).

The electronic device (110) can identify a state corresponding to each of the received key information (S340). The states include a first, second, and third state, and the first state may indicate the start of barcode input, the second state may indicate the progress of barcode input, and the third state may indicate the completion of barcode input.

Specifically, the state identified by the electronic device (110) can be divided into a first state, a second state, and a third state. The first state is a state indicating the start of barcode input, and can indicate the moment when the user activates the barcode scanner (120) or inputs the first barcode data. Referring to FIG. 5, for example, the first state can be the onStartScan method. The onStartScan method is a method called when barcode input or barcode scanning starts in the electronic device (110), and can notify the start of barcode input.

In one embodiment, the first state may cause the electronic device (110) to initialize an input string, set a boolean value corresponding to the first state to true, and store key information corresponding to the first state.

The second state is a state indicating that barcode input is in progress, and may include a process in which the entire data of the barcode is input. Referring to FIG. 5, for example, the second state may be the OnChangeScan method. The OnChangeScan method is a method that is called when data changes during scanning in the electronic device (110), and can check and output intermediate data.

In one embodiment, the second state may cause the electronic device (110) to sequentially add the received key information to the input string if the Boolean value is true.

The third state is a state indicating that the barcode input is complete, which may mean that all barcode data has been completely input and scanning has ended. Referring to FIG. 5, for example, the third state may be an OnFinishScan method. The OnFinishScan method is called when scanning is completed in the electronic device (110), and allows the electronic device (110) to generate and store the final data as an input string. In addition, the third state may include a function that can initialize the scan state. This may reset the current operating state of the scan system, allowing the user to start a new scan operation from the initial state. It will be appreciated that it may be beneficial to utilize the third state to troubleshoot errors or problems that may occur during a barcode input operation.

In one embodiment, the third state may cause the electronic device (110) to store the sequentially entered input string if no additional key information is received and the Boolean value is true, and set the Boolean value to false.

In one embodiment, identifying a state corresponding to each of the received key information may include identifying the state corresponding to one of the key information as a third state if the value of one of the received key information is a specific key value.

Specifically, the electronic device (110) can determine whether one key information among the received key information has a specific key value. The specific key value may be a predefined value, for example, an enter value. If one key information among the received key information includes enter, the key information is identified as a third state. At this time, it can be seen that the third state is a special state that is distinct from the previous two states and indicates completion of barcode input. The specific key value is not limited to enter, and may be any predefined key value.

In FIG. 3, the electronic device (110) can generate an input string corresponding to the barcode collected by the barcode scanner (120) based on key information corresponding to the state (S350). That is, the electronic device (110) can generate the barcode data collected by the barcode scanner (120) into an input string based on key information corresponding to the first, second, and third states.

In one embodiment, a first state may cause the electronic device (110) to initialize an input string and set a boolean value corresponding to the first state to true, a second state may cause the electronic device (110) to sequentially add received key information to the input string if the boolean value is true, and a third state may cause the electronic device (110) to store the input string if no additional key information is received and the boolean value is true and set the boolean value to false.

The electronic device (110) finally processes the received barcode data, converts it into an input string format, and can store it or use it for additional processing. Referring to FIG. 5, the OnFinishScan method is a method called when the barcode input is completed in the electronic device (110), and allows the electronic device (110) to generate and store the final data as an input string. The input string generation (Build Input String) represents a step of generating an input string based on the received key information.

Further explanation is given in Fig. 5.

The User Interface layer represents the steps where a user attempts to connect an electronic device (110) and a barcode scanner (120). If the connection between the electronic device (110) and the barcode scanner (120) is successful, the barcode input process may be started, and if it fails, it may be terminated. Additionally, user input and initial device settings may be performed on the electronic device (110).

The library layer can perform the task of receiving key events occurring from the barcode scanner (120) and converting them into corresponding states. The electronic device (110) can play an important role as an intermediate step of processing input data and generating state information.

The electronic device (110) receives a series of key information from the barcode scanner (120) and can process the received key information. The electronic device (110) can provide the final stored input string to each view model for processing. Specifically, the electronic device (110) can provide the input string to a necessary location among each function of the application through a callback listener. The callback listener refers to a function or method that is called to process a specific event when it occurs so that the electronic device (110) can provide the input string to a necessary location among each function of the application. When the electronic device (110) receives the input string through the callback listener, it can transfer it to an appropriate view model (e.g., OneScan view model, Map view model, List view model). In this way, each function of the application can receive and process necessary data in real time.

A view model is an object that manages and integrates properties and commands between the application's UI (view) and data (model). View models can optimize the interaction between data and UI in each area of responsibility.

For example, the OneScan view model can be responsible for processing and managing a single scan task within a logistics application. The OneScan view model can include functions to collect and validate scan data entered by the user and pass the data to the appropriate model object. The OneScan view model manages all state changes and UI updates related to a single scan task, and can display scan results to the user when necessary. The Map view model can process and manage scan tasks related to maps. It can manage scan data containing specific location information on a map, and convert the data into geographic coordinates or addresses and display them on the map. In addition, the Map view model can handle various interactions performed by the user on the map, and can perform functions including updating map data and finding optimized routes. The List view model is a view model that processes and manages scan tasks related to lists. It manages multiple scan data using a list-type data structure, and can handle tasks such as adding, deleting, and modifying each data item. The List view model can efficiently display list-type data to the user by linking it to the UI, and can load and display related detailed information when a specific item in the list is selected.

Fig. 6 is a flowchart showing a logistics information search and classification process corresponding to a barcode input string according to an embodiment. This flowchart consists of steps S610, S620, and S630.

In one embodiment, the electronic device (110) can search for logistics information corresponding to an input string (S610). The input string is a specific character string and can be used as a reference for finding related logistics information in a database or server (150). Meanwhile, since the result scanned by the barcode scanner (120), i.e., the input string, is not limited to one of return, delivery, and product recall, the electronic device (110) can perform various logistics functions. Due to a single scan action, the electronic device (110) can comprehensively manage other logistics tasks such as return processing, delivery status tracking, and product recall requests. A person skilled in the art will understand that a user can perform various functions required for logistics through a single scan action.

Logistics information includes logistics types, and logistics types can include returns, delivery, and product recalls. Returns refer to the process of returning purchased products. Delivery refers to the process of delivering products from sellers, intermediaries, or merchants to buyers. Delivery can include shipment, transportation, and final delivery stages after product orders. In product recalls, products refer to items not intended for sale. Specifically, they are not sold directly to consumers through commercial transactions, but can include tools used for delivery and storage of products for sale. Representative examples include boxes for delivery, ice boxes, and packing boxes, and these products can protect products and enable rapid delivery.

In an additional embodiment, the electronic device (110) can retrieve logistics information corresponding to the input string through the server (150).

The electronic device (110) can transmit logistics information to the server (150) so that the server (150) classifies the logistics information by product code, date of receipt, or date of shipment (S610). The electronic device (110) can secure a plurality of logistics information through the server (150). The logistics information can include information for return, delivery, and product recall, and can include various attribute values such as product code, date of receipt, and date of shipment of the product. For example, the logistics information can include information such as delivery status, product requiring delivery, recall status, product requiring recall, whether it is assigned to a user for delivery, recall, product recall, etc., waybill number information, expiration date of the waybill, and whether delivery, recall, and product recall are complete.

Additionally, for example, the delivery status refers to the status of the product being delivered, and may include states such as preparing for delivery, in delivery, delivery complete, and delivery delay. Products requiring delivery refer to products that are currently ready to be delivered to customers, and may include products packed according to order, products awaiting shipment, and the like. The recall status refers to the status of products requiring return or recall, and may include states such as recall request received, recall in progress, recall complete, and recall delay. Products requiring recall may include products for which a return has been requested, or defective products requiring recall, and may include products requested for return, products subject to defective recall, and the like.

As described above, logistics information constitutes important data in a logistics management system, and it plays an important role in being able to grasp and control the movement status and management status of products in real time. The server (150) receives and manages a large amount of logistics information, thereby enabling efficient logistics processing and customer service provision. This structure can contribute to preventing various issues that may occur in the logistics process in advance and to promoting systematic problem solving.

The electronic device (110) can perform a function of transmitting the collected logistics information to the server (150). The server (150) can use the received logistics information to perform a classification task based on specific criteria. For example, if classified by product code, product information corresponding to each code can be grouped and managed. If classified by receipt date, data can be organized based on products received on a specific date, making inventory management and tracking easy. If classified by shipping date, history management of products shipped on a specific date can be efficiently managed.

The server (150) classifies and manages logistics information based on various factors such as delivery status, products requiring delivery, retrieval status, products requiring retrieval, whether assigned to a user for delivery and retrieval or product retrieval, waybill number information, validity period of waybill, and whether delivery and retrieval or product retrieval is complete. For example, if classified based on delivery status, products currently being delivered, products that have been delivered, products that require delivery, etc. can be managed separately. If classified based on retrieval status, products that have been retrieval completed, products that require retrieval, etc. can be systematically identified. Additionally, the server (150) can classify logistics information based on criteria such as origin, destination, type of goods, and delivery status. In addition, more sophisticated management is possible by utilizing waybill number information to manage the validity period for a specific waybill or by classifying logistics information by waybill number.

The server (150) classifies and manages logistics information whenever it is created or updated, and can transmit it to an electronic device (110) if necessary.

In one embodiment, the electronic device (110) may receive the logistics information classified by the server (150) from the server (150) (S620). The electronic device (110) may receive the classified logistics information from the server (150) via the network (140). Additionally, the electronic device (110) may receive the logistics information and store the information or prepare it to be used in another process. The classified logistics information may be useful for tracking the expected arrival time of an item or for confirming the current location of a specific item.

FIG. 7 is a diagram showing an application according to one embodiment of the present invention that scans a barcode and displays scanned waybill information on the application screen.

In Fig. 7, the left screen (710) shows the process of scanning the barcode of the waybill. The user interface (UI) displays the scan status and shows the scanned barcode image. The right screen (720) of Fig. 7 shows the list of scanned waybills. The electronic device (110) displays the scanned waybill information in the form of a list and can provide detailed information for each waybill.

To this end, in one embodiment, the electronic device (110) may determine the input string as a waybill number corresponding to a barcode scanned by the barcode scanner (120). The input string may be directly associated with the waybill number. The electronic device (110) may determine the value of the input string as the waybill number, and may track or manage the transportation status of the goods accordingly.

In one embodiment, the electronic device (110) may verify the validity of the determined waybill number. For example, the electronic device (110) may verify that the waybill number complies with a predefined format or protocol to prevent the use of an invalid or incorrect waybill number.

In a further embodiment, the electronic device (110) can detect the length of the waybill number to detect whether the number satisfies a predetermined number of digits. In a further embodiment, the electronic device (110) can compare the format of the waybill number, such as the position of specific letters or the arrangement of numbers, with a predetermined pattern. In a further embodiment, the electronic device (110) can apply a specific verification code to the waybill number to determine whether the calculated verification code matches the waybill number.

In addition, the electronic device (110) can access the central server (150) or database through the network (140) to verify validity by checking whether the corresponding waybill number is within the registered range and whether it is a valid number that has not already been used. This verification process plays an important role in maintaining the integrity of the waybill number and minimizing errors that may occur during the transportation process.

The validity of the waybill number can be verified by considering various cases. For example, in an additional embodiment, the electronic device (110) may include at least one of the following steps to verify the validity of the determined waybill number: (i) determining whether the waybill number overlaps with another waybill number already stored; (ii) determining whether the transportation validity period corresponding to the waybill number has expired; (iii) determining whether the waybill number corresponds to a waybill number assigned to a user of the electronic device (110) in a database on the server (150); (iv) determining whether the waybill number has already been processed for delivery completion; (v) determining whether the waybill number has been assigned to another user.

The electronic device (110) can compare the determined waybill number with other waybill numbers stored in the database to check for duplication. If there is a duplicate waybill number, an error message can be output or the user can be requested to re-enter it.

Additionally, the electronic device (110) can check whether the waybill number is no longer valid after a certain period of time has passed since the waybill number was issued. If the validity period has expired, the electronic device can output that the waybill number cannot be used or request the user to re-enter it.

Additionally, the electronic device (110) can determine whether the waybill number is a waybill number actually assigned to the user of the electronic device (110) in the database on the server (150). Specifically, the electronic device (110) can check whether the input waybill number is assigned to the user. If it is not an actually assigned waybill number, an error message can be output or the user can be requested to re-enter it.

Additionally, the electronic device (110) can determine whether the waybill number has already been processed for delivery completion in the database on the server (150). The electronic device (110) can check whether delivery using the waybill number has already been completed, and if delivery has been completed, can output an error message or request the user to re-enter the information.

Additionally, the electronic device (110) may determine whether the tracking number has been assigned to another user from the database on the server (150). If the electronic device (110) determines whether the tracking number has been assigned to another user, it may output an error message or request the user to re-enter the number.

In one embodiment, the electronic device (110) may display a message corresponding to the verification result. This is described with reference to FIG. 8A. FIG. 8A illustrates a successful barcode input, a duplicate scan, and an error according to one embodiment of the present invention.

As shown in the screen (810) of Fig. 8a, if the waybill barcode is successfully scanned while the barcode scanner (120) is connected to the electronic device (110), a success message may be displayed on the electronic device (110). At this time, although not shown, if the waybill barcode is successfully scanned, the electronic device (110) may display the following as waybill information: the determined waybill number; the number of scanned waybills; the number of unscanned waybills. Such information may help the user perform waybill management and tracking tasks more efficiently.

Referring to the screen (820) of FIG. 8A and FIG. 8B, when a duplicate scan occurs, a duplicate message may be displayed on the electronic device (110). In one embodiment, the electronic device (110) may display an image of a duplicated waybill. A duplicate scan means a case where the same waybill is scanned more than twice. When a duplicate scan occurs, the electronic device (110) may identify it and display a warning message to the user. This warning message may include a visual or auditory signal. In particular, when the electronic device (110) displays an image of a duplicated waybill, the user may check in real time whether there is a duplicate scan. This allows the user to avoid unnecessary data input or prevent duplicate processing of already processed data.

Screen (830) of Fig. 8a shows a case where a scan error occurs while the barcode scanner is connected, and this illustrates a case where the determined waybill number is not a normal waybill number. The electronic device (110) may display a message indicating that the waybill is not a normal waybill as an error message. At this time, the electronic device (110) may provide an input field where the waybill number can be directly input, and the user may directly input the waybill number through this field.

In addition, the electronic device (110) may have a function to inform the user of various error situations. For example, the electronic device (110) may inform the user through a message “This is not a normal waybill” when the input waybill number is not recognized by the system. This may mean that the waybill entered by the electronic device (110) does not follow the format or rules registered in the system. For example, the electronic device (110) may inform the user through a message “This is an unassigned waybill” that the input waybill number is not assigned to the user of the electronic device (110) in the server (150) database and is therefore invalid. For example, the electronic device (110) may inform the user through a message “This is an already delivered waybill” that the corresponding waybill has already been processed as delivered. For example, the electronic device (110) may inform the user through a message “This is an already assigned waybill to another user” that the input waybill number has been assigned to another user.

Additionally, the electronic device (110) may guide the system to take appropriate action when a system error or other problem occurs by sending a message such as “Please contact the administrator.”

In one embodiment according to the present disclosure, an application for managing a barcode scanner (120) may be installed in an electronic device (110), and the electronic device (110) may specify one or more indicators for the usage history of the application for service reporting, analyze the usage history according to the indicators, and log the results of the analysis.

Specifically, the electronic device (110) can specify one or more indicators of the usage history of the application. As used herein, “indicators” refer to metrics utilized to evaluate various characteristics of an application. Such indicators may include the effectiveness of the application, the frequency of use, and whether problems occur. For example, the effectiveness of an application may indicate how well the application performs a function or service provided to a user, and the frequency of use may mean how often the application is used during a specific period of time. The occurrence of problems may evaluate such things as the frequency of errors or unexpected behaviors that occur during the use of the application. Such indicators provide important data for improving and optimizing the application.

Additionally, the indicator may include at least one of service availability, error occurrence frequency, and error occurrence history. Service availability is an indicator indicating whether the system operates normally during the time provided to the user. The electronic device (110) can measure the time for which the system can operate without interruption through this. Error occurrence frequency is an indicator indicating the number of times an error occurs in the system. The electronic device (110) can evaluate the stability and performance of the system through this. Error occurrence history is an indicator that records the type and cause of an error that occurred in the system.

The electronic device (110) can monitor application usage history in real time and collect data. The electronic device (110) can receive and process data from various sensors and communication modules. Thereafter, the memory of the electronic device (110) can store the collected data and make it accessible to an analysis tool. The electronic device (110) can preserve the history of application usage history and allow additional operations required to specify an indicator to be performed.

Thereafter, the communication module of the electronic device (110) may communicate data with an external server (150) or a cloud system, so that the usage history and indicators of the application may be transmitted to the server (150) to enable comprehensive analysis. In an additional embodiment, the electronic device (110) may analyze the usage history of the application according to a specified indicator. The electronic device (110) may evaluate the current status and performance of the application through a process of collecting and processing log data, user feedback, performance metrics, etc.

In one embodiment, the electronic device (110) can log the analyzed results. The electronic device (110) can structure the analyzed data and re-record it, or report the logged records to an external system. The logging can include the time, date, and other relevant information of the data. Additionally, the electronic device (110) can structure the analyzed data in a specific format and re-record it. The structured data can exist in various forms, and can be visualized in the form of a table or graph, for example. The structured data can be stored in an internal database of the system, or can be transmitted to an external storage as needed.

Additionally, the electronic device (110) can report logged records to an external system. The electronic device (110) can transmit data to a server (150), a cloud service, or another external system.

The electronic device (110) can additionally provide the current status of the application, usage history, possible problems, etc. visually or audibly through the user interface.

In one embodiment according to the present disclosure, specifying one or more indicators by the electronic device (110) may include determining whether the communication method with the barcode scanner (120) is a Human Interface Device (HID) method. Specifically, there may be various ways in which the electronic device (110) communicates with the barcode scanner (120), and determining whether the communication is in the HID method is important for scalability.

The electronic device (110) can use a specific protocol or command to connect to the application and check whether the barcode scanner (120) used is recognized as an HID device. If recognized in the HID manner, the electronic device (110) processes the input data transmitted through the barcode scanner (120) and can thereby specify the necessary indicator.

In one embodiment, the determination of whether the electronic device (110) uses the HID method may be performed simultaneously with the process of recognizing the barcode scanner (120). This may include a task of automatically determining whether the barcode scanner (120) uses the HID method when the electronic device (110) is connected to and operated by the electronic device (110). For example, when the electronic device (110) recognizes the barcode scanner (120), the communication method or data transmission protocol of the scanner is analyzed to determine whether it uses the HID method. It will be understood that this determination task may be performed in real time whenever the barcode scanner (120) is used, and no separate manual work or additional settings are required.

In an additional embodiment, the method of checking whether the electronic device (110) uses the HID method can be done by recording through a log. This means that the electronic device (110) records all activities that occur in the process of attempting to communicate with a specific device or establishing a connection. By analyzing such log records, it is possible to check whether a specific device uses the HID method. For example, the electronic device (110) records the connection attempt and data transmission process with the barcode scanner (120) in a log, and the use of the HID method can be reviewed and confirmed later through the log. This method may be somewhat delayed compared to checking whether the HID method is used in real time, but has the advantage of leaving a record so that it can be reviewed later.

In one embodiment according to the present disclosure, the step of specifying one or more indicators may include the step of determining a connection status with a barcode scanner (120) and information of the barcode scanner (120).

In one embodiment of the present disclosure, the step of specifying one or more indicators may include a step of determining a connection status with the barcode scanner (120) and information of the barcode scanner (120). Specifically, the electronic device (110) may determine a connection status with the barcode scanner (120). This is to evaluate whether the barcode scanner (120) is normally connected to the electronic device (110), and is determined regardless of whether the connection is wired or wireless. Additionally, the electronic device (110) may determine information of the barcode scanner (120). This means examining specific identification information (e.g., serial number, model number, firmware version, etc.) of the barcode scanner (120). This information may be required to determine whether the barcode scanner (120) is operating normally or for subsequent data processing and services. It will be appreciated that this configuration can ensure the stability and reliability of the system.

In one embodiment according to the present disclosure, specifying one or more indicators by the electronic device (110) may include determining tasks performed on the application and the frequency of the tasks.

Specifically, the electronic device (110) may include a function to monitor and record a series of tasks performed by the user in the application user interface or in the background. The tasks may be implemented in various forms, such as specific actions related to services required for logistics, such as cargo tracking, inventory management, order processing, and delivery status confirmation. By tracking these tasks, the electronic device (110) may calculate the frequency with which each task is performed and statistically analyze this frequency. Through this, the electronic device (110) may identify specific tasks or behavioral patterns that have the greatest impact on the user and derive indicators based on this information. These indicators may be utilized as basic data for improving the user experience.

In one embodiment according to the present disclosure, specifying one or more indicators by the electronic device (110) may include detecting that occurrence of a key input event was determined by an element other than the event listener; and in response to detecting that occurrence of the key input event was determined by an element other than the event listener, determining the occurrence of an error.

Specifically, the electronic device (110) can detect whether the occurrence of a key input event is recognized by an element other than the event listener. For example, when a user attempts to scan a barcode, another system element may recognize it before a general event listener captures it, so that the occurrence of the event may not be detected. If the occurrence of a key input event is detected by an element other than the event listener, it is determined as an error. That is, if the event listener does not normally detect a key input event, it can be viewed as an error.

In additional or alternative embodiments, an error may be determined to have occurred in response to the event listener not determining the occurrence of a key press event within a predetermined time period after the barcode entry has been initiated. The predetermined time period here means a time interval preset by the system, which is set for the purpose of ensuring user experience and system reliability. For example, the predetermined time period may be 500ms, 600ms, 700ms, etc.

For example, if the event listener fails to process a key input event within 2 seconds after the barcode input has started, the electronic device (110) may determine this as an error. The error determination step serves as an important part of verifying that the system is operating correctly, and through this, it is possible to quickly notify the user of any problems that may occur during the input process.

In additional embodiments, the predetermined time can be extended depending on the situation. For example, the predetermined time can be flexibly adjusted based on system performance or user needs to optimize the user experience. Thus, if the event listener fails to process a key input event within the predetermined time, it can be recognized and acted upon quickly.

In one embodiment of the present disclosure, the electronic device (110) may generate a notification when an error occurrence frequency exceeds a preset threshold.

Specifically, the electronic device (110) can monitor errors occurring within the system in real time. These may include software errors, hardware errors, network (140) errors, etc. The error occurrence frequency calculated by the electronic device can be compared with a preset threshold value. This threshold value may be a value defined in advance to ensure the stability of the system. The electronic device (110) can generate a notification when the error occurrence frequency exceeds the preset threshold value. The notification can be delivered in various forms such as email, SMS, and push notification.

In one embodiment according to the present disclosure, determining whether a key input event has occurred by the electronic device (110) may include: receiving whether a key input event has occurred at predetermined time units; and detecting duplicate events among the key input events received at predetermined time units, and ignoring the detected duplicate events.

The electronic device (110) can receive whether a key input event has occurred at a predetermined time unit. This means monitoring whether a key input event has occurred at a regular time interval and receiving it at each time interval. For example, this refers to a process in which the electronic device (110) checks whether a key input event has occurred at 100 ms units.

The electronic device (110) can detect duplicate events among key input events received at predetermined time units and ignore the detected duplicate events. If the same key input event occurs repeatedly, the electronic device (110) can consider it as a duplicate event and exclude the duplicate event. For example, in a situation where a user continuously presses a key, the remaining inputs except for the first key input can be ignored so as not to process the occurrence of duplicate events. It will be understood that the key input event can be efficiently processed through this.

One embodiment of the present invention includes an electronic device including one or more processors and one or more memories storing instructions to be executed by the one or more processors. When the instructions are executed by the one or more processors, the one or more processors may be configured to execute a method according to any one of the embodiments described above.
