Description

Technical Field

[0001] This application relates to the field of transportation technology, and in particular to a container number identification device. Background Technology

[0002] In the transportation system, containers are the carriers of goods. A container number is a unique code within the container transportation system, consisting of the container's model, volume, owner, and serial number. In railway container transportation, railway vehicles are added as carriers. After the containers are loaded onto the vehicles, the container number and railway vehicle information need to be manually verified. This manual on-site verification process is time-consuming, inefficient in container loading and unloading, and prone to errors.

[0003] To address this, existing devices employ identification mechanisms. These typically include a base, four sets of fixed posts secured to the top of the base, sliding movable posts inside the four sets of fixed posts, and the identification body itself mounted on a mounting frame. A bidirectional motor is located on top of the motor. Through the interaction between a top roller and a fixed plate, the swinging plate moves the top roller, which in turn pushes against the fixed plate, causing the mounting frame and the identification device to move upwards. This changes the height of the identification body, enabling the identification of container numbers at different heights. However, this type of device is relatively large and inconvenient to carry, thus failing to meet the identification needs of container numbers in different scenarios and at different heights. Utility Model Content

[0004] Therefore, it is necessary to provide a container number identification device that is easy to carry and can effectively meet the identification needs of container numbers in different scenarios and at different heights, thereby improving the convenience of the device.

[0005] A container number identification device includes: a housing; a camera component and a display component, respectively spaced apart on the outer surface of the housing, the camera component being used to acquire image information of the container number; and an identification component, disposed inside the housing and electrically connected to the camera component and the display component, the identification component being used to identify character information in the image information acquired by the camera component and to transmit the character information to the display component.

[0006] The aforementioned container number recognition device acquires image information from the container via a camera component when identifying container numbers. The acquired image information is then processed by a recognition component to extract character information, which is displayed on a display component. Thus, when acquiring container numbers at different scenes or heights, only image information needs to be acquired via the camera component, eliminating the need for motors or other equipment to drive the recognition device to climb, effectively meeting the recognition needs of container numbers at different scenes and heights. Furthermore, the camera component, display component, and recognition component are all integrated into the housing, simplifying the structural design, facilitating portability, and improving the ease of use of the recognition device.

[0008] In some embodiments, the container number identification device further includes a light source located between the first camera and the second camera.

[0009] In some embodiments, the outer surface of the housing includes a front and a back facing each other, the first camera and the second camera are respectively spaced apart on the back, and the first control key, the second control key and the display component are spaced apart on the front.

[0010] In some embodiments, the container number identification device further includes a verification key and an input component. The verification key and the input component are spaced apart on the outer surface of the housing and are both electrically connected to the display component. The verification key is used to control the character information of the display component to switch between an editing state and a confirming state, and the input component is used to input character information into the display component.

[0012] In some embodiments, the container number identification device further includes a power source disposed within the housing for providing electrical power to the container number identification device.

[0013] In some embodiments, the container number identification device further includes a charging port located on the housing and electrically connected to the power source.

[0014] In some embodiments, the container number identification device further includes a protective sleeve that is fitted over the housing.

[0015] In some embodiments, the protective sleeve is constructed as a ring-shaped structure, which surrounds itself to form an installation cavity, and the opposite sides of the protective sleeve have a first opening and a second opening communicating with the installation cavity, respectively.

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0021] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0022] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0023] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0024] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0025] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0026] In some embodiments, please refer to Figures 1 to 3 This application provides a container number identification device 100, which includes a housing 10, an imaging component 30, a display component 20, and an identification component 40. The imaging component 30 and the display component 20 are respectively disposed at a distance from each other on the outer surface of the housing 10. The imaging component 30 is used to acquire image information of the container number. The identification component 40 is disposed inside the housing 10 and electrically connected to both the imaging component 30 and the display component 20. The identification component 40 is used to identify character information in the image information acquired by the imaging component 30 and transmit the character information to the display component 20.

[0027] The aforementioned container number recognition device 100, when recognizing container numbers, acquires image information from the container via the imaging component 30; the acquired image information is then recognized by the recognition component 40 to extract character information from the image information and display it on the display component 20. Thus, when recognizing container numbers in different scenarios or at different heights, only image information needs to be acquired via the imaging component 30, eliminating the need for motors or other equipment to drive the recognition device 100 to climb, effectively meeting the recognition needs of container numbers in different scenarios and at different heights. Furthermore, the imaging component 30, display component 20, and recognition component 40 are all integrated into the housing 10, simplifying the structural design, facilitating portability, and improving the ease of use of the recognition device 100.

[0028] It should be noted that the imaging component 30 refers to a device capable of acquiring image information, such as, but not limited to, complementary metal-oxide-semiconductor (CMOS) or charge-coupled device (CCD). Of course, the structure of the imaging component 30 may also include lenses, etc.

[0029] After the imaging component 30 acquires the image information of the container number, the recognition component 40 can recognize and extract the characters in the image information. These characters can be numbers, letters, or other similar data. The structure of the recognition component 40 can be varied, including, but not limited to, a graphics processing unit (GPU) or a central processing unit (CPU) with optical character recognition (OCR) capabilities. Since the communication circuit between the recognition component 40 and the imaging component 30 is not the focus of this embodiment, its circuit connection will not be described in detail here.

[0030] Furthermore, the acquired character information can be sent to the display component 20 for display. Of course, in some examples, the acquired character information can also be transmitted to a terminal for storage, facilitating container tracking. Similarly, the circuit structure between the display component 20 and the recognition component 40 is not the focus of this embodiment and will not be described in detail.

[0031] Further, please refer to Figure 1 and Figure 2 The container number identification device 100 also includes a first control key 50 and a second control key 51. The imaging component 30 includes a first camera 31 and a second camera 32, which are spaced apart on the outer surface of the housing 10. The first control key 50 and the second control key 51 are also spaced apart on the outer surface of the housing 10 and are respectively connected to the first camera 31 and the second camera 32 for control. The shooting angle of the first camera 31 is greater than that of the second camera 32. Therefore, the imaging component 30 has two different shooting angle functions. When it is necessary to obtain a container number that is far away, the first control key 50 can be used to activate the first camera 31 to obtain image information from a relatively distant location. When it is necessary to obtain a container number that is closer, the second control key 51 can be used to activate the second camera 32 to obtain image information from a closer location. This design can effectively meet the identification needs of container numbers at different heights, greatly improving the application range of the identification device 100.

[0032] It should be noted that the shooting angle of the first camera 31 is greater than that of the second camera 32, allowing it to capture a wider range of image information. In some specific examples, the first camera 31 may be a wide-angle or ultra-wide-angle camera, while the second camera 32 may be a standard camera.

[0033] Meanwhile, the first control key 50 and the second control key 51 can respectively control the operation of the first camera 31 and the second camera 32. For example, when the first control key 50 is triggered, the first camera 31 is in working state and acquires image information of the container number; when the second control key 51 is triggered, the second camera 32 is in working state and acquires image information of the container number.

[0034] Please refer to the following: Figure 3 One end of the first control key 50 and the second control key 51 can be connected to a pin of the processor 70, such as a pin of a microcontroller. When the first control key 50 or the second control key 51 is pressed, the level of the pin can change from high to low, triggering an interrupt or polling detection. At this time, after receiving the button signal, the single-row machine sends a control command to the first camera 31 or the second camera 32 through the I / O port or communication interface to make it work. The specific circuit structure between the first control key 50, the second control key 51, the first camera 31, and the second camera 32 is not the subject of this embodiment.

[0035] In some embodiments, please refer to Figure 2 The container number identification device 100 also includes a light source 33, which is located between the first camera 31 and the second camera 32. Therefore, placing the light source 33 between the first camera 31 and the second camera 32 ensures that the light source 33 can provide equal illumination to both cameras, thus improving image quality.

[0036] For specific examples, please refer to Figure 2 The first camera 31 and the second camera 32 are spaced apart along the width of the housing 10, and the light source 33 is positioned between the first camera 31 and the second camera 32. Simultaneously, when either the first camera 31 or the second camera 32 is in operation, the light source 33 automatically activates to provide illumination for shooting, ensuring the brightness of the image information to meet the requirements of character recognition.

[0037] In some embodiments, please refer to Figure 1 and Figure 2 The outer surface of the housing 10 includes a front side 11 and a back side 12 facing away from each other. The first camera 31 and the second camera 32 are respectively spaced apart on the back side 12, and the first control key 50, the second control key 51, and the display component 20 are spaced apart on the front side 11. Thus, the camera component 30 and the display component 20 are located on opposite sides of the housing 10, allowing the housing 10 to capture images of the container number on one side and view the character information on the display component 20 on the other side, facilitating operation.

[0038] In some embodiments, please refer to Figure 1The container number identification device 100 also includes a calibration key 60 and an input component 61. The calibration key 60 and the input component 61 are spaced apart on the outer surface of the housing 10 and are both electrically connected to the display component 20. The calibration key 60 is used to control the switching of the character information on the display component 20 between an editing state and a confirming state. The input component 61 is used to input character information into the display component 20. Therefore, when manually calibrating the character information displayed on the display component 20, if garbled characters or discrepancies with the actual characters are found, the calibration key 60 can trigger the character information in the display component 20 to enter an editing state. At this time, the operator can manually input the correct character information through the input component 61, which will then be displayed on the display component 20. After display, the calibration key 60 can be pressed again to bring the character information in the display component 20 to a confirming state. This design further improves the accuracy and reliability of the identification device 100.

[0039] It should be noted that pressing the calibration key 60 triggers the character information in the display component 20 to enter edit mode, allowing modification or re-entry of the character information via the input component 61. When the calibration key 60 is pressed again, the character information in the display component 20 is in a fixed state and cannot be edited further. However, pressing the calibration key 60 again will put the character information in the display component 20 back into edit mode.

[0040] The character information in display component 20 switches between edit and confirm states. This can be achieved by editing the program code so that the proofreading key 60 can control the character information in display component 20. Please refer to [the relevant documentation / reference]. Figure 3 When the calibration key 60 is pressed, the processor 70 receives the pressing signal and controls the character information in the display component 20 to be in editing mode.

[0041] In addition, when the container number identification device 100 also includes a first control key 50 and a second control key 51, the calibration key 60 may be located between the first control key 50 and the second control key 51.

[0042] In some embodiments, please refer to Figure 1 The input component 61 includes multiple input keys 611, all of which are arranged in a matrix, and each input key 611 is located between the display component 20 and the calibration key 60. This design facilitates input operations for the operator.

[0043] The input keys 611 can be designed as a 9-key layout or a 26-key layout.

[0044] In addition, when the container number identification device 100 also includes a first control key 50 and a second control key 51, the first control key 50, the correction key 60 and the second control key 51 are linearly spaced along the width direction of the housing 10, and all input keys 611 are distributed between the display component 20 and the first control key 50.

[0045] In some embodiments, please refer to Figure 2 The container number identification device 100 also includes a power supply 14, which is located inside the housing 10 and is used to provide power to the container number identification device 100. It is understood that having the power supply 14 built into the housing 10 facilitates outdoor operations and avoids situations where there is no power supply 14 outdoors. At the same time, it also makes it convenient for operators to carry the device with them, greatly improving the ease of use of the identification device 100.

[0046] It should be noted that the power source 14 can be of various types, such as, but not limited to, lithium batteries, zinc-manganese batteries, nickel-cadmium batteries, and nickel-metal hydride batteries. Furthermore, the number of power sources 14 can be determined according to actual needs, such as, but not limited to, one, two, or three.

[0047] Further, please refer to Figure 2 The container number identification device 100 also includes a charging port 13, which is located on the housing 10 and electrically connected to the power supply 14. Therefore, when the power supply 14 is low on power, it can be recharged through the charging port 13 to ensure sufficient power for identification work under outdoor mobile conditions.

[0048] The charging port 13 can be designed in various ways, such as, but not limited to, Micro USB, Type-C, Lightning, etc.

[0049] In some embodiments, please refer to Figure 1 The container number identification device 100 also includes a protective sleeve 80, which is fitted over the housing 10. In this way, the housing 10 is protected by the protective sleeve 80 to prevent the identification device 100 from being damaged by falling during outdoor operations, thus ensuring its safe use in outdoor mobile environments.

[0050] Further, please refer to Figure 1 and Figure 2The protective sleeve 80 is constructed as a ring-shaped structure, forming an installation cavity within itself. The opposite sides of the protective sleeve 80 have a first opening 81 and a second opening 82 communicating with the installation cavity. The imaging component 30 and the display component 20 are respectively disposed on opposite surfaces of the housing 10. When the housing 10 is inserted into the installation cavity, the display component 20 and the imaging component 30 are exposed from the first opening 81 and the second opening 82, respectively. Therefore, under the premise of ensuring safe use, exposing the display component 20 and the imaging component 30 through the first opening 81 and the second opening 82 allows the identification device 100 to operate stably.

[0051] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
