[0006] The present invention relates to a logistics management system with improved transportation efficiency. According to one embodiment of the present invention, the logistics management system comprises: a central server that collects information on transport vehicles capable of loading goods, operation information of the transport vehicles, and goods loaded on the transport vehicles; and uses the collected information to reset the dispatch of transport vehicles and the arrangement of goods at transfer points; and a transfer point server located at the transfer point that receives information regarding the dispatch of transport vehicles and the arrangement of goods at the transfer point set by the central server.

[0007] (Patent Document 3) Republic of Korea Patent No. 10-2077279

[0008] In a method for operating a logistics management system, the method includes a step of bringing in an object; a step of placing the brought-in object on a mounting structure; and a step of removing the object from the mounting structure, wherein the mounting structure includes a plurality of first frames provided vertically and a plurality of second frames provided vertically on the first frames. Accordingly, a suitable means for bringing in and removing the object itself is provided in the operation of a logistics management system.

[0009] However, in the case of these conventional technologies, in today's world where the volume of logistics delivery is rapidly increasing, if a transporter directly checks the temperature, humidity, and shock information inside the vehicle to check the condition of the logistics loaded onto the vehicle and manually writes a paper certificate, a lot of time can be wasted, which reduces transportation efficiency.

[0010] Therefore, a method is needed to improve transport efficiency by having the person transporting the logistics directly grasp the logistics status information within the logistics vehicle and transmit it directly to the manager or customer without having to manually write a paper certificate.

[0011] The present invention, which aims to solve the above-described problems, aims to sense at least one of temperature, acceleration, humidity, illuminance, inclination, impact, and position within a logistics vehicle delivering logistics and provide a status data set within the logistics vehicle in the form of a QR code.

[0012] In addition, the present invention seeks to generate a QR code and provide it to the user at the time the user requests the QR code or at a period specified by the user when forming the QR code.

[0013] In addition, the present invention seeks to configure a logistics vehicle so that it can be recycled when it is scrapped or its purpose is changed.

[0014] The problems to be solved by the present invention are not limited to the problems mentioned above, and other problems not mentioned will be clearly understood by those skilled in the art from the description below.

[0015] The present invention for solving the above-described problem is a device for performing smart logistics monitoring, comprising: a display unit, a memory; a sensor unit for sensing at least one of temperature, acceleration, humidity, illuminance, inclination, impact, and position within a logistics vehicle; and a control unit for generating status information of logistics according to the sensing result of the sensor unit at preset intervals, generating each QR code representing each status information, and displaying the generated QR code on a screen of the display unit, wherein each QR code can be switched and displayed on the screen according to the order in which it is generated.

[0016] In addition, the input unit further includes a plurality of buttons, and the control unit can display, on the screen, a QR code corresponding to the time when the first button of the input unit is pressed among each of the QR codes.

[0017] Additionally, each of the above QR codes may be sequentially changed and displayed each time the first button is pressed.

[0018] In addition, the input unit further includes a plurality of buttons, and the control unit can set a specific time zone according to a second button input of the input unit, and search for at least one QR code generated in the set specific time zone among each of the QR codes and display the searched QR code on the screen.

[0019] In addition, the system further includes a communication unit that performs communication with an external device, and the control unit can transmit information notifying of the occurrence of an abnormality in the logistics to the external device when an abnormality in the logistics is detected based on status information generated at each preset cycle.

[0020] In addition, the control unit can transmit a QR code at the time when the logistics abnormality occurred so that it is displayed on the AVN (Audio video navigation) screen of the logistics vehicle.

[0021] In addition, the control unit can perform an authentication process for an external terminal when an external terminal attempts to recognize a QR code displayed on the screen.

[0022] In addition, the device further includes a communication unit that performs communication with the external device, and the control unit can transmit a request signal for authentication information to the external terminal through the communication unit and determine whether authentication is successful based on the authentication information received from the external terminal.

[0023] Additionally, the control unit may display the QR code when the authentication is successful, and may stop displaying the QR code or display a dummy QR code indicating fake information when the authentication fails.

[0024] Additionally, the device can be collected from the logistics vehicle and recycled when the logistics vehicle is scrapped or repurposed.

[0025] In addition, other methods for implementing the present invention, other systems, and computer-readable recording media recording a computer program for executing the above methods may be further provided.

[0026] According to the present invention as described above, by sensing at least one of temperature, acceleration, humidity, illuminance, inclination, impact, and position within a logistics vehicle delivering logistics and providing status information within the logistics vehicle in the form of a QR code, if a user is equipped with a terminal capable of recognizing a QR code and a corresponding app, a cumbersome process can be omitted and the user can easily recognize the QR code through the terminal, thereby easily and accurately and conveniently checking the status within the logistics vehicle and taking necessary measures.

[0027] In addition, according to the present invention, the procedure for checking the status inside a logistics vehicle can be simplified, thereby enabling an integrated monitoring service, thereby increasing efficiency, and also has the effect of minimizing the issuance of many paper certificates, such as certification documents and inspection reports, that had to be submitted each time during the basic distribution process.

[0028] In addition, according to the present invention, when forming a QR code, the QR code is generated and provided to the user at the time the user requests the QR code or at a period specified by the user, thereby reducing the risk of hacking and preventing manipulation of the logistics status, thereby increasing the reliability of the data.

[0029] In addition, according to the present invention, the user can set the QR code to a desired period and recognize it, thereby enabling a distributor or seller to obtain status information for a desired period.

[0030] In addition, according to the present invention, when a logistics vehicle is scrapped or its purpose is changed, it is configured to be recyclable, thereby reducing waste of the device and resulting in cost savings.

[0044] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings.

[0045] FIG. 1 is a schematic diagram of a system (1) that performs smart logistics monitoring according to the present invention.

[0046] Figure 2 is a block diagram schematically showing a device (10) that performs smart logistics monitoring according to the present invention.

[0047] Figure 3 is a drawing showing a device (10) that performs smart logistics monitoring according to the present invention.

[0048] Figure 4 is a block diagram schematically showing an external terminal (20) according to the present invention.

[0049] Hereinafter, with reference to FIGS. 1 and 4, a system (1) for performing smart logistics monitoring of the present invention will be described. Here, the system (1) may include fewer or more components than the components illustrated in the drawings of FIGS. 1 to 4.

[0050] A system (1) for performing smart logistics monitoring may include a device (10) that is attached to and detached from a logistics vehicle transporting logistics and generates status information within the logistics vehicle, an external terminal (20) that recognizes a QR code provided by the device (10), an external device (30) that receives the QR code, and a communication network (40).

[0051] The system (1) senses at least one of temperature, acceleration, humidity, illuminance, inclination, impact, position, and proximity within a logistics vehicle (2) that delivers logistics, and provides status information within the logistics vehicle to a device (10) in the form of a QR code, so that when a user is equipped with an external terminal (20) capable of recognizing a QR code and a corresponding app, the user can easily recognize the QR code through the external terminal (20) without a cumbersome process, thereby having the effect of easily, accurately, and conveniently checking the status within the logistics vehicle and taking necessary measures.

[0052] Here, the status information refers to at least one of the following: temperature, humidity, and lighting conditions that must be maintained in an appropriate environment for the logistics; the incline at which the contents of the logistics must be loaded to prevent spillage or spillage; impact on fragile logistics such as glass; and the transportation location of the logistics. The status information required for the storage or transportation of the logistics is preset and used. For example, if the product is bottled milk, the status information of the logistics may include temperature or humidity changes that can be stored without spoiling the milk, or the strength of the impact force to prevent the bottle from breaking. It is desirable that the above logistics status information basically include location information indicating the location of the logistics. This is to enable sellers and buyers to accurately and promptly inform the transportation location of the logistics they manage or purchase, given the nature of logistics.

[0053] In addition, the above system (1) can simplify the procedure for checking the status within the logistics vehicle (2), thereby enabling an integrated monitoring service, thereby increasing efficiency, and can also have the effect of minimizing the issuance of many paper certificates, such as certification documents and inspection reports, that had to be submitted each time during the basic distribution process.

[0054] In addition, the above system (1) can have the effect of increasing the reliability of data by generating and providing a QR code to the user at the time the user requests the QR code or at a period specified by the user, thereby reducing the risk of hacking and preventing manipulation of the logistics status.

[0055] In addition, the above system (1) is configured so that the user can set the QR code to a desired period and recognize it, thereby having the effect of allowing distributors or sellers to easily obtain status information for the period they wish to check.

[0056] In addition, the above system (1) is configured to enable recycling of the device (10) when the logistics vehicle (2) is scrapped or its purpose is changed, thereby reducing waste of the device (10) and resulting in cost savings.

[0057] The device (10) can be configured to be attached to and detached from a logistics vehicle (2) that delivers logistics and sense at least one of temperature, acceleration, humidity, illuminance, inclination, impact, position, and proximity to provide status information within the logistics vehicle (2) in the form of a QR code. Here, logistics refers to goods to be transported and goods that need to be protected from deterioration, temperature changes, and external impacts during the transport process. The device (10) can record the status information in a QR code and enable the status information to be checked by reading the QR code through an external terminal (20) that can recognize the QR code.

[0058] Here, since the device (10) is detachable, when the logistics vehicle (2) is scrapped or its purpose is changed, it can be collected from the logistics vehicle (2) and recycled.

[0059] Referring to FIG. 1, the device (10) is illustrated as being installed in one logistics vehicle (2), but is not necessarily limited to this, and multiple devices may be installed in the logistics vehicle (2), and may be installed in a form that can be attached or detached anywhere inside the logistics vehicle (2).

[0060] The device (10) may be configured to include a first communication unit (110), a sensor unit (120), a first input unit (130), a first display unit (140), a first memory (150), and a first control unit (160). Here, the device (10) may include fewer or more components than the components illustrated in the drawings of FIGS. 2 and 3.

[0061] The first communication unit (110) may include one or more modules that enable wireless communication between the device (10) and a wireless communication system, between the device (10) and an external terminal (20), or between the device (10) and an external device (30). In addition, the first communication unit (110) may include one or more modules that connect the external terminal (20) to one or more networks.

[0062] In addition, the first communication unit (110) is a module for obtaining the location (or current location) of the device (10), and representative examples thereof may include a GPS (Global Positioning System) module or a WiFi (Wireless Fidelity) module. For example, if the device (10) utilizes a GPS module, the location can be obtained using signals transmitted from GPS satellites. As another example, if the device (10) utilizes a Wi-Fi module, the location can be obtained based on information from a wireless AP (Wireless Access Point) that transmits or receives wireless signals with the Wi-Fi module. The first communication unit (110) is not limited to directly calculating or obtaining the location of the device (10).

[0063] The sensor unit (120) can sense at least one of temperature, acceleration, humidity, illuminance, inclination, impact, position, and proximity within the logistics vehicle. The sensor unit (120) can sense information about the surrounding environment surrounding the device (10) and generate a sensing signal corresponding thereto. Based on this sensing signal, the first control unit (160) can control the operation or behavior of the device (10), or perform data processing, functions, or operations related to an application program installed in the device (10).

[0064] The sensor unit (120) may include, for example, at least one of a proximity sensor, an illumination sensor, an acceleration sensor, a G-sensor, a gyroscope sensor, a motion sensor, an infrared sensor (IR sensor), a fingerprint recognition sensor (121, finger scan sensor), an optical sensor, an ultrasonic sensor, an infrared ray sensor, an environmental sensor (e.g., a barometer, a hygrometer, a thermometer, a radiation detection sensor, a heat detection sensor, a gas detection sensor, etc.), and a chemical sensor (e.g., a healthcare sensor, a biometric recognition sensor, etc.). In addition, the sensor unit (120) may additionally include a location sensor capable of determining a location. Meanwhile, the device (10) disclosed in the present specification may utilize information sensed by at least two or more of these sensors in combination.

[0065] Here, a proximity sensor refers to a sensor that detects the presence of an object approaching a predetermined detection surface or an object present nearby without mechanical contact, using electromagnetic fields or infrared rays. Such a proximity sensor may be placed within an external terminal covered by the touch screen discussed above, or near the touch screen.

[0066] The first input unit (130) is for inputting image information (or signal), audio information (or signal), data, or information input from a user. For inputting image information, the device (10) may be equipped with at least one first camera (131). The first camera (131) may process image frames, such as still images or moving images, obtained by an image sensor in a shooting mode. The processed image frames may be displayed on the first display unit (140) or stored in the first memory (170). In addition, the first camera (131) may include at least one of a camera for recognizing an iris and a camera for capturing an image.

[0067] The first input unit (130) may include at least one button among a start or screen on / off button (132), a time setting button (133), and an adjustment button (134) for displaying a QR code. Here, the button may be both a physical hardware button and a virtual button displayed on a touchscreen, and in the case of a virtual button, it may be generated on a first display unit (140) in the form of a touchscreen. When a user pushes the on / off button (132) for a preset time or longer, the device (10) may be shut down, and when a user pushes the on / off button (132) at short intervals, the screen of the device (10) may be turned on or off.

[0068] The first display unit (140) can be formed as a touch screen by forming a mutual layer structure with the touch sensor or by forming an integral structure. This touch screen can provide an input interface between the device (10) and the user, and at the same time, an output interface between the device (10) and the user. The first display unit (140) can display a QR code provided by the device (10).

[0069] The first memory (150) can store data supporting various functions of the device (10), and in particular, can store a QR code. The first memory (150) can store a plurality of application programs (or applications) running on the device (10), data for the operation of the device (10), and commands. At least some of these application programs can be downloaded from an external server (not shown) via wireless communication. In addition, at least some of these application programs can exist for the basic functions of the device (10). Meanwhile, the application programs can be stored in the first memory (150), installed on the device (10), and driven by the first control unit (160) to perform the operation (or function) of the device (10).

[0070] In addition to operations related to the application program, the first control unit (160) can typically control the overall operation of the device (10). The first control unit (160) can process signals, data, information, etc. input or output through the components discussed above, or can operate an application program stored in the first memory (150) to provide or process appropriate information or functions to the user.

[0071] In addition, the first control unit (160) can control at least some of the components discussed with reference to FIG. 2 to drive an application program stored in the first memory (150). Furthermore, the first control unit (160) can operate at least two or more of the components included in the device (10) in combination to drive the application program.

[0072] The first control unit (160) can generate status information of logistics based on the sensing results of the sensor unit (120) at preset intervals, and can generate the QR code by paging the status information at preset intervals or in real time. Here, the QR codes can be displayed on the screen in a switched manner according to the order in which they were generated, and the QR image can continuously change until the number of units of the status information is filled.

[0073] QR codes are two-dimensional structures that can store up to 7,089 numeric characters, 4,296 letters, and 1,817 Chinese characters, utilizing horizontal and vertical dimensions. QR codes can contain a wide range of information, including long internet addresses (URLs), photos and videos, maps, and business cards. The more small square dots a QR code has, the more information it can store. However, this increases the required area. QR codes also excel in recognition speed, accuracy, and resilience compared to standard barcodes. As their name suggests, they enable "quick response." Recently, QR codes have become a key corporate promotional and marketing tool, and are widely used both online and offline. Furthermore, the square shape of QRS codes allows for accurate recognition from any angle. Because QR codes are largely unaffected by background images, they can be embedded in a variety of promotional and advertising materials. While conventional one-dimensional barcodes can only store about 20 numeric characters, QR codes can store up to 7,089 numeric characters, 4,296 ASCII characters, 2,953 binary bytes, and 1,817 Chinese characters. They also boast superior recognition speed, recognition rate, and resilience compared to standard barcodes. While barcodes are primarily used for checkout, inventory management, and product verification, QR codes are widely used for marketing, promotional, and PR purposes.

[0074] Furthermore, since only sellers possess dedicated external terminals capable of reading existing barcodes, consumers were unable to access information using barcodes. However, with QR codes, consumers can access product information directly with just a smartphone. Smartphone users can download a free QR code scanning app and scan QR codes displayed on billboards, flyers, posters, magazines, and online to easily access various information.

[0075] The first control unit (160) can generate each QR code representing each status information, store each QR code in the first memory (150), and display each QR code on the screen of the display unit. Here, each QR code can be switched and displayed on the screen according to the order in which it was generated.

[0076] The first control unit (160) can display, on the screen, a QR code corresponding to the time when the first button of the first input unit (130), for example, the adjustment button (133), is pressed among each of the above QR codes. Here, each of the above QR codes can be sequentially changed and displayed each time the first button (133) is pressed.

[0077] The external terminal (20) may be an electronic device capable of recognizing a QR code, carried by a delivery person delivering logistics, a person managing logistics, etc. Here, the external terminal (20) may include any type of handheld-based wireless communication device that can be connected to a web server via a network, such as a mobile phone, a smart phone, a PDA (Personal Digital Assistant), a PMP (Portable Multimedia Player), a tablet PC, etc.

[0078] The external terminal (20) may include a second communication unit (210), a second input unit (220), a second display unit (230), a second memory (240), and a second control unit (250). Here, the external terminal (20) may include fewer or more components than the components illustrated in FIG. 2.

[0079] The second communication unit (210) may include one or more modules that enable wireless communication between an external terminal (20) and a wireless communication system, between the external terminal (20) and a device (10), between the external terminal (20) and an external device (30), or between the external terminal (20) and an external server (not shown). In addition, the second communication unit (210) may include one or more modules that connect the external terminal (20) to one or more networks.

[0080] The second input unit (220) is for inputting image information (or signal), audio information (or signal), data, or information input from a user. For inputting image information, the external terminal (20) may be equipped with at least one second camera (221) on the front or rear. The camera may process image frames, such as still images or moving images, obtained by an image sensor in a video call mode or a shooting mode. The processed image frames may be displayed on the second display unit (230) or stored in the second memory (240). Meanwhile, at least one second camera (221) equipped in the external terminal (20) may be arranged to form a matrix structure, and through the second cameras (221) forming the matrix structure in this way, a plurality of image information having various angles or focal points may be input to the external terminal (20). In addition, the second camera (221) may be arranged in a stereo structure to obtain left and right images for implementing a three-dimensional image.

[0081] The second camera (221) can capture images or videos according to the user's operation. Here, the second camera (221) may be a recognition device that can capture a QR code provided by the device (10) according to the user's operation.

[0082] The second input unit (220) is for receiving information from the user. When information is input through the second input unit (220), the second control unit (250) can control the operation of the external terminal (20) to correspond to the input information. The second input unit (220) may include a mechanical input means (or a mechanical key, for example, a button located on the front, back, or side of the external terminal (100), a dome switch, a jog wheel, a jog switch, etc.) and a touch input means. As an example, the touch input means may be composed of a virtual key, a soft key, or a visual key displayed on a touch screen through software processing, or a touch key placed on a part other than the touch screen. Meanwhile, the virtual key or visual key may be displayed on the touch screen in various forms, and may be formed of, for example, graphics, text, icons, videos, or a combination thereof.

[0083] The second display unit (230) can be formed as a touch screen by forming a mutual layer structure with the touch sensor or by forming an integral structure. Such a touch screen can provide an input interface between an external terminal (20) and a user, and at the same time, provide an output interface between the user's external terminal (20) and the user.

[0084] When the second camera (221) of the second input unit (220) recognizes a QR code provided by the device (10), the second display unit (230) can display the recognized QR code and status information included in the recognized QR code.

[0085] The second memory (240) can store data that supports various functions of the external terminal (20). The second memory (240) can store a plurality of application programs (or applications) running on the external terminal (20), data for the operation of the external terminal (20), and commands. At least some of these application programs can be downloaded from an external server via wireless communication. In addition, at least some of these application programs can exist for the basic functions of the external terminal (20) (e.g., call receiving, calling, message receiving, calling). Meanwhile, the application programs can be stored in the second memory (240), installed on the external terminal (20), and driven by the second control unit (250) to perform the operations (or functions) of the external terminal (20).

[0086] In addition to the operations related to the application program, the second control unit (250) can typically control the overall operations of the external terminal (20). The second control unit (250) can process signals, data, information, etc. input or output through the components discussed above, or can operate an application program stored in the second memory (240) to provide or process appropriate information or functions to the user.

[0092] FIG. 5 is an exemplary diagram showing a QR code displayed on a device (10) according to a user's time zone input according to the present invention.

[0093] The device (10) may be equipped with a first input unit (130) including a start or screen on / off button (132), a time setting button (133), and an adjustment button (134) for displaying a QR code. The first control unit (160) of the device (10) may set a specific time zone according to an input of a second button, for example, a time setting button (133), of the first input unit (130), and search for at least one QR code generated in the set specific time zone among the respective QR codes and display the searched QR code on the screen (501). Alternatively, the first control unit (160) of the device (10) may set a specific time zone according to an input of a second button, for example, a time setting button (133), of the first input unit (130), and generate at least one QR code based on status information corresponding to the set specific time zone and display the searched QR code on the screen (501).

[0094] Looking at the device (10) shown on the left side of Fig. 5, when a user inputs the 'start' button among the adjustment buttons (134), the first control unit (160) of the device (10) can display the QR code of the first time point when the user inputs the 'start' button among the adjustment buttons (134) on the screen (501) of the first display unit (140).

[0095] In addition, as shown in FIG. 5, the adjustment button (134) may be provided with a right arrow button and a left arrow button located on both sides of the 'start' button. When the user inputs the left arrow button among the adjustment buttons (134), the first control unit (160) of the device (10) may display a QR code before the reference time on the screen (501) of the first display unit (140). Alternatively, when the user inputs the right arrow button among the adjustment buttons (134), the first control unit (160) of the device (10) may display a QR code after the reference time on the screen (501) of the first display unit (140). Here, the reference time may be a time set by the user through the time setting button (133) or the current time.

[0096] Looking at the device (10) shown on the right side of FIG. 5, when a user inputs the start time for checking status information as 14:25:00 on September 16, 2020 and the end time as 15:30:30 on October 1, 2020 through the time setting button (132), the first control unit (160) of the device (10) can display at least one QR code for status information on the screen (501) of the first display unit (140) between the start time and the end time.

[0097] In addition, looking at the device (10) shown on the right side of FIG. 5, when the user inputs the 'start' button again at a second point in time after a certain period of time has elapsed from the first point in time when the user inputs the 'start' button among the adjustment buttons (133), the first control unit (160) of the device (10) can generate and display in real time a QR code at the second point in time that is different from the QR code at the first point in time on the screen (501) of the first display unit (140).

[0098] FIG. 6 is an exemplary diagram showing changes in screen brightness and magnification of a QR code when a QR code is displayed on a device (10) according to the present invention.

[0099] The first control unit (160) of the device (10) can control the screen brightness of the first display unit (140) to be increased to a preset brightness or higher whenever the QR code is displayed on the screen (601).

[0100] The first control unit (160) of the device (10) can control the logistics vehicle (2) by transmitting a signal for commanding the turn-on of the interior light (602) in the logistics vehicle (2) through the first communication unit (110) so that the interior light (602) is automatically turned on whenever the QR code is displayed on the screen (601). Here, the first control unit (160) can further detect the proximity of an external terminal (20) that recognizes the QR code through the proximity sensor of the sensor unit (120), and change the magnification of the QR code according to the proximity between the external terminal (20) and the first display unit (140) sensed through the sensor unit (120).

[0101] Fig. 7 is an exemplary diagram of the operation of a device (10) for notifying the occurrence of an abnormality when an abnormality occurs in status information according to the present invention.

[0102] Referring to FIG. 7, when the first control unit (160) of the device (10) detects that an abnormality has occurred in the logistics based on status information generated at preset intervals, it can transmit information notifying of the occurrence of the abnormality in the logistics to the external terminal (20) or the external device (30), or transmit it so that it is displayed on the AVN (31, Audio video navigation) screen of the logistics vehicle (2).

[0103] The first control unit (160) of the device (10) can periodically transmit the information to the external terminal (20) or the external device (30) until the status of the logistics becomes normal.

[0104] The first control unit (160) of the device (10) can include the first QR code at the time when the logistics abnormality occurred in the information notifying the logistics abnormality and transmit it to an external device, for example, the external terminal (20) or the external device (30). Here, the external terminal (20) may be a terminal used by a delivery person who drives a logistics vehicle (2) to deliver logistics, and the external device (30) may be a logistics central server, a server of a manufacturer that sent logistics, a server of a customer that receives logistics, etc.

[0105] The first control unit (160) of the device (10) can include the first QR code at the time when the logistics abnormality occurred in the information notifying the occurrence of the logistics abnormality and transmit it so that it is displayed on the AVN (Audio video navigation) screen of the logistics vehicle (2).

[0106] The first control unit (160) of the device (10) can include location information at the time of occurrence of a logistics abnormality and the first QR code in information notifying the occurrence of the logistics abnormality and transmit it to the external device (30).

[0107] The first control unit (160) of the device (10) can include the QR code at the time when the logistics abnormality occurred in the information notifying the logistics abnormality and transmit it to the external device (30) together with the QR code before the logistics abnormality occurred. Here, the manager using the external device (30) can clearly compare the occurrence of the logistics abnormality through the first QR code at the time when the logistics abnormality occurred and the second QR code before the logistics abnormality occurred, which are displayed on the external device (30).

[0108] Here, the first control unit (160) can generate a lookup table matching the location information with the first QR code and the second QR code and store it in the first memory (150). Thereafter, the first control unit (160) can generate statistical information on the point where the most logistics abnormalities occur and the fluctuation range of the sensing value for each status information based on the first QR code and the second QR code for each location information stored in the lookup table.

[0109] In addition, the first control unit (160) of the device (10) can capture an image of the logistics inside the logistics vehicle (2) at the time when an abnormality in the logistics occurs through a black box (camera) inside the logistics vehicle (2), and transmit the captured image to the external device (30) by including it in information notifying the occurrence of the abnormality in the logistics.

[0110] FIG. 8 is an example of the operation of the device (10) when an external terminal (20) attempts to recognize a QR code displayed on the device (10) according to the present invention.

[0111] Referring to FIG. 8, the first control unit (160) of the device (10) can perform an authentication process for the external terminal (20) when recognition of the QR code displayed on the screen of the device (10) is attempted by the external terminal (20). Here, recognition of the recognition attempt can be performed by recognizing the approach of the external terminal (20) through the proximity sensor of the sensor unit (120), recognizing the approach of the external terminal (20) through the first camera (121) included in the sensor unit (120), and recognizing the approach of the external terminal (20) through the ultrasonic sensor or infrared sensor of the sensor unit (120).

[0112] The first control unit (160) of the device (10) can recognize the fingerprint of the user of the external terminal (20) through the fingerprint recognition sensor (121) of the sensor unit (120) and perform an authentication process for the external terminal (20) based on this. Alternatively, the first control unit (160) of the device (10) can recognize the iris of the user of the external terminal (20) through the iris recognition camera among the first cameras (131) of the first input unit (130) and perform an authentication process for the external terminal (20) based on this.

[0113] The first control unit (160) of the device (10) can transmit a request signal for authentication information to the external terminal (20) through the first communication unit (110) and determine whether authentication is successful based on the authentication information received from the external terminal (20).

[0114] The first control unit (160) of the device (10) can display the QR code or transmit the status information paged to the QR code to the external terminal (20) when the external terminal (20) is authenticated based on the authentication status.

[0115] The first control unit (160) of the device (10) can generate a re-authentication request signal for authentication information and transmit it to the external terminal (20) if the external terminal (20) is not authenticated based on the authentication status.

[0116] The first control unit (160) of the device (10) may, when the authentication fails, send a re-authentication request signal to the external terminal (20) by default, and, when the re-authentication fails more than a preset number of times, generate a dummy QR code representing fake information and display the dummy QR code on the screen instead of the QR code. Alternatively, the first control unit (160) of the device (10) may, when the re-authentication fails more than a preset number of times, display another preset image (for example, access prohibited) instead of the QR code, or turn off the screen on which the QR code is displayed and then lock the screen.

[0117] FIG. 9 is a flowchart showing a process of controlling smart logistics monitoring in a device (10) according to the present invention.

[0118] The first control unit (160) of the device (10) can obtain at least one of temperature, acceleration, humidity, illuminance, inclination, impact, and position inside the logistics vehicle sensed through the sensor unit (120) (S901).

[0119] The first control unit (160) can generate status information of logistics according to the sensing results of the sensor unit (120) at each preset cycle (S902).

[0120] The first control unit (160) can generate each QR code representing each of the above status information (S903).

[0121] The first control unit (160) can display each of the QR codes on the screen of the device (10) (S904).

[0122] For example, the first control unit (160) can display, on the screen, the QR code corresponding to the time when the first button of the first input unit (130) is pressed among each of the QR codes.

[0123] Here, each of the above QR codes can be sequentially changed and displayed each time the first button is pressed.

[0124] As another example, the first control unit (160) may set a specific time zone according to the input of the second button of the input unit (130), and search for at least one QR code generated in the set specific time zone among each of the QR codes and display it on the screen.

[0125] If the first control unit (160) detects that an abnormality has occurred in the logistics based on the status information generated at each preset cycle, it can transmit information notifying of the occurrence of the abnormality in the logistics to the external device (S905).

[0126] Here, the first control unit (160) can transmit the QR code at the time when the logistics abnormality occurred so that it is displayed on the AVN (Audio video navigation) screen of the logistics vehicle.

[0127] When an external terminal attempts to recognize a QR code displayed on the screen, the first control unit (160) can perform an authentication process for the external terminal (S906).

[0128] Here, the first control unit (160) can transmit a request signal for authentication information to the external terminal through the first communication unit (110), and determine whether authentication is successful based on the authentication information received from the external terminal.

[0129] The first control unit (160) can display the QR code when the authentication is successful (S907).

[0130] Meanwhile, the first control unit (160) may directly recognize a QR code containing (or indicating) website address information through the second camera (221) of the external terminal (20), without going through the application. Accordingly, when the external terminal (20) recognizes the QR code through the second camera (221), it may be connected to the specific website. In this case, the specific website may be a website (e.g., homepage) that provides product status information. In addition, the address information may include the URL (Uniform Resource Locator) of the website.

[0131] If the authentication fails, the first control unit (160) can stop displaying the QR code or display a dummy QR code indicating fake information (S908).

[0132] While the embodiments of the present invention have been described with reference to the attached drawings, those skilled in the art will appreciate that the present invention can be implemented in other specific forms without altering the technical concept or essential features thereof. Therefore, the embodiments described above should be understood to be illustrative in all respects and not restrictive.
