Description

Technical Field

[0001] The utility model relates to the field of security inspection, in particular to a special keyboard for security inspection. Background Art

[0002] In security inspection scenarios involving manual image interpretation, manual input is required via keyboard input. Ordinary computer keyboards contain many keys and are not specifically designed for security inspection scenarios. Some security inspection manufacturers currently manufacture full-function keyboards specifically for security inspection scenarios. However, these full-function keyboards often strive to cover all keyboard functions required for security inspections, resulting in a large number of keys, ranging from 20 to 30. This large number of keys presents several challenges: first, the learning cost for security personnel is high, requiring a long period of study to familiarize themselves with the layout of the keys on the keyboard, and achieving blind typing requires even more time and practice; second, the large number of keys also results in a larger keyboard, requiring a larger footprint. Utility Model Content

[0003] In view of this, the utility model provides a special keyboard for security inspection, which can effectively save the learning cost of security inspection personnel and improve the convenience of use for security inspection personnel.

[0004] In a first aspect of the embodiments of the present disclosure, a security inspection keyboard is provided.

[0015] Figure 2 The structural diagram of the security inspection-specific keyboard in an embodiment of the present disclosure is schematically shown. DETAILED DESCRIPTION

[0016] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present disclosure. In the following detailed description, for ease of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present disclosure. However, it is obvious that one or more embodiments can also be implemented without these specific details. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present disclosure.

[0017] The terms used herein are only for describing specific embodiments and are not intended to limit the present disclosure. The terms "comprise," "include," etc. used herein indicate the presence of the features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.

[0018] After in-depth research into manual image interpretation scenarios in the security inspection field, the inventors discovered that different keystrokes for different functions have different timeliness requirements. Specifically, during the brief period when a target (such as luggage or a person undergoing inspection) passes through and exits the security inspection equipment, security personnel must quickly and accurately determine whether the target has passed inspection based on the images captured by the equipment. Therefore, the keystrokes used in this process require extremely high timeliness. These keys primarily fall into two categories: those used to determine whether the target has passed inspection, and those used for image processing functions (such as zooming in, out, and brightening) during the image interpretation process to aid accurate image interpretation. Other functions, such as logging into the security inspection system and entering an account name and password at the beginning of each inspection period, and periodic and irregular uploads of records or data, require relatively low timeliness and frequency.

[0019] In view of this, the inventors considered that function keys with relatively high timeliness requirements in security inspection scenarios could be prominently set on the keyboard (for example, through size, layout, color, shape or touch, etc.), while for functions with relatively low timeliness requirements (relatively low frequency), the key functions could be concentrated by triggering the shortcut keys of the software disk. This highlights the high-frequency and high-timeliness keys in security inspection scenarios, making it easier for security personnel to use them and reducing their learning costs. Moreover, concentrating key functions by triggering the shortcut keys of the software disk can also help streamline the number of keys, which is conducive to reducing the size of the keyboard. In addition, considering that there may be special needs or some needs that are difficult to determine in advance, some custom keys can be reserved and customized by the user according to actual conditions.

[0020] Based on this, the embodiment of the present disclosure provides a special keyboard for security inspection. Figure 1~Figure 2 , and gives a detailed introduction to the structure and use of this security inspection special keyboard.

[0021] Figure 1 An application scenario 100 of a security inspection-specific keyboard according to an embodiment of the present disclosure is schematically shown.

[0022] like Figure 1 As shown, the application scenario 100 may include a security inspection dedicated keyboard 101 , a security inspection image recognition station host 102 and a security inspection image recognition station display screen 103 .

[0023] The security inspection dedicated keyboard 101 is a security inspection dedicated keyboard according to an embodiment of the present disclosure.

[0024] The security inspection image recognition station host 102 has a built-in processor. The security inspection keyboard 101 is communicatively connected to the security inspection image recognition station host 102, enabling communication between the keyboard 101 and the processor. The connection between the keyboard 101 and the security inspection image recognition station host 102 can be wired or wireless. When the security inspection keyboard 101 and the security inspection image recognition station host 102 are connected via a wired connection (e.g., via a USB port), the keyboard 101 can be passively powered, with power supplied by the security inspection image recognition station host 102, enabling plug-and-play operation and reducing the keyboard's size.

[0025] The security inspection and image recognition station display screen 103 is in communication connection with the security inspection and image recognition station host 102 .

[0026] The image recognition program software adapted to the security inspection special keyboard 101 is installed and run on the security inspection image recognition station host 102. The security inspection image recognition station host 102 realizes simple human-computer interaction with the user through the security inspection image recognition station display screen 103 and the security inspection special keyboard 101.

[0027] Figure 2 The structural diagram of the security inspection-specific keyboard in an embodiment of the present disclosure is schematically shown.

[0028] like Figure 2 As shown, the security inspection keyboard 101 may include at least two first buttons 11, M second buttons 12, and one third button 13. The value of M is a positive integer less than 10.

[0029] The first button 11 is used to determine whether the target has passed the security check during the security check. The two first buttons 11 can correspond to whether the target has passed the security check or not.

[0030] The second button 12 is used to process the image of the collected target during the security inspection process. As shown in the figure, the second button 12 containing the symbol "+" can be used to enlarge the image, the second button 12 containing the symbol "-" can be used to reduce the image, and the second button 12 containing the character "ESC" can be used to undo the previously performed image processing operation. The second buttons 12 containing the symbols "F1", "F2", and "F3" are buttons that can be customized to configure image processing functions. Specifically, security personnel can freely define different functional effects according to their preferences. Among them, in the embodiment of the present disclosure, the number M of the second buttons 12 is less than 10, which can limit the number of buttons, reduce the learning cost on the one hand, and reduce the size of the keyboard on the other.

[0031] The third button 13 is used to trigger the soft keyboard. Specifically, when the third button 13 is pressed, a signal for triggering the soft keyboard is sent to the security inspection and image recognition station host 102 to trigger the display of the software disk on the security inspection and image recognition station display screen 103.

[0032] In the disclosed embodiment, the size of the first button 11 is larger than that of the second button 12, and the size of the second button 12 is not smaller than that of the third button 13. This ensures that the first button 11 is at least the largest on the keyboard and larger than the other two types of buttons. This allows the first button 11, which is highly time-sensitive, to be highlighted. This allows security personnel to quickly and efficiently master the first button 11 and operate it with high accuracy, greatly improving the efficiency of image interpretation by security personnel.

[0033] When setting the sizes of the second button 12 and the third button 13, in some embodiments, the following can be done: Figure 2 As shown, some of the second keys 12 are larger than the third keys 13, while others are the same size as the third keys 13. The specific second keys 12 that are larger can be determined based on how frequently they are used or the key layout. By setting different sizes for different functions within the second keys 12, a portion of the image processing keys can be distinguished, making it easier for users to learn and touch-type while also reducing the overall size of the keyboard.

[0034] Of course, in some embodiments, the size of all second keys 12 can be set to be larger than the size of the third key 13. In this way, the key sizes of the security inspection keyboard 101 can be divided into three levels: large, medium, and small. Among them, the medium-sized keys are all image processing function keys. This makes it easier for key operators to quickly and accurately distinguish the types of keys based on the key sizes, saving learning costs and facilitating blind typing.

[0035] In the embodiment of the present disclosure, the function of one of the two first buttons 11 can be that the target passes the security check (such as the button marked with the symbol "×" on the left), and the corresponding function of the other one can be that the target fails the security check (such as the button marked with the symbol "√" on the right). In this way, each first button 11 has a fixed function option, and the function is clear.

[0036] In some embodiments, the two first buttons 11 can also be set to different colors. For example, the surface of one of the two first buttons 11 can be set to green and the other to red, so that security personnel can use their peripheral vision to scan the color of the buttons to assist in blind typing accuracy, achieving visual distinction. In other embodiments, the two first buttons 11 can be set to have different tactile sensations. For example, the surface roughness of the two first buttons 11 can be set to be different, or a touch mark (such as a bump) can be added to only one of the first buttons 11, or a protruding symbol "×" and a symbol "√" can be set on the two first buttons 11 respectively, or the contour shapes of the two first buttons 11 can be set to be different (such as one with sharp edges and the other with a rounded transition), etc.

[0037] Furthermore, in the disclosed embodiment, two first buttons 11 are located in a first area, and M second buttons 12 are located in a second area, wherein the second area and the first area do not overlap. Thus, by isolating the first buttons 11 and the second buttons 12 to a certain extent in the layout, the button functions can be divided, thereby reducing the user's learning cost for the buttons.

[0038] In some further embodiments, the third key 13 may also be arranged in the first area, between the two first keys 11, so as to achieve a symmetrical arrangement of the first keys 11 and an aesthetically pleasing appearance of the keys in the keyboard.

[0039] In addition, in some embodiments, the two first buttons 11 are arranged side by side in the first area, wherein the area between the sides of the two first buttons 11 facing away from each other and the edge of the dedicated security inspection keyboard 101 serves as the frame of the dedicated security inspection keyboard 101. In this way, the dedicated security inspection keyboard 101 is convenient for the user to hold with one hand, wherein the two first buttons 11 are convenient for the user to operate alternately with two fingers.

[0040] According to an embodiment of the present disclosure, each of the M second buttons 12 corresponds to one or more operating functions. The operating functions corresponding to the M second buttons 12 include but are not limited to zooming in on an image, zooming out on an image, flipping an image, brightening, dimming, adjusting contrast, sharpening, and the like. When a second button 12 corresponds to multiple operating functions, the second buttons corresponding to different operating functions have different operating modes. For example, different operating functions can be distinguished by single-clicking, double-clicking, triple-clicking, or long-pressing the same second button 12. For example, Figure 2 The second button 12, which includes a "+" symbol, can be used to magnify the image by a predetermined magnification when single-clicked, and to continuously magnify the image when long-pressed, which is more in line with the operating habits of image processing. In this way, security personnel can either single-click a button to quickly process the image and submit the security inspection conclusion, or continue pressing the button to achieve a gradual and continuous image change effect.

[0041] According to some embodiments of the present disclosure, the security inspection keyboard 101 may further include at least one fourth button 14. The size of the fourth button 14 is no larger than that of the third button 13. The fourth button 14 may be a reserved user-defined button. For example, in some security inspection scenarios, when a "high risk" command is issued when a target high-risk item is clearly identified, the fourth button 14 may be configured as a "high risk" function.

[0042] When the fourth button 14 and the third button 13 have the same size, the layout of the fourth button 14 and the third button 13 can be used to help the user quickly distinguish between the fourth button 14 and the third button 13. Figure 2 The fourth button 14 is located between the two first buttons 11 .

[0043] When the size of the fourth button 14 is smaller than the third button 13 , it can facilitate blind typing for the user, improve the accuracy of blind typing, and also reduce the size of the button.

[0044] I understand. Figure 2 The inclusion of only one fourth button 14 in the embodiment is merely an example. In practice, multiple fourth buttons 14 may be reserved, and then combined with image interpretation software compatible with the security inspection keyboard 101, this can provide users with a certain degree of autonomy and flexibility. Of course, in some embodiments, to minimize the security inspection keyboard 101 while meeting the requirements of security inspection scenarios, the number of keys on the security inspection keyboard 101 may be limited to no more than 10. This reduces the number of keys that security inspectors need to learn and become familiar with, and also reduces the floor space required. In extremely tight and limited spaces such as passenger security inspection lanes, this makes it possible to reduce the size of the image interpretation workstation, thereby reducing its footprint and freeing up more space for security inspections.

[0045] In application scenario 100, while a target is passing through security, the security personnel's corresponding operation of the first button 11 or the second button 12 (or the fourth button 14) can be received, allowing a quick determination of whether the target has passed security. In other situations where timeliness is less critical, the security personnel's operation of the third button 13 can be received, and a software disk can be called up on the security inspection image interpretation station display 103 to assist the security personnel in completing the corresponding operation. In this way, by streamlining the keyboard keys and concentrating the functions of less time-sensitive keys on the third button 13, the system not only meets security inspection requirements but also streamlines the key layout and facilitates operation. Furthermore, by integrating software functions, it can support more uncommon and personalized functions, providing considerable flexibility.

[0046] Moreover, since the security inspection keyboard 101 has key size settings that highlight the first key 11 and the second key 12, which have relatively high timeliness requirements, and adds some tactile discrimination, layout settings, color prompts, etc., security personnel can complete operations accurately and quickly without looking at the keyboard. This allows security personnel to focus more on the displayed image on the security inspection image judgment station display screen 103 during the keystroke process, reducing the probability of missed detection and improving the efficiency of security inspection image judgment.

[0047] According to other embodiments of the present disclosure, the dedicated security keyboard 101 may further include an alarm device, which may include, for example, at least one alarm indicator light 15 and / or a buzzer. The buzzer may be located within the dedicated security keyboard 101. When the dedicated security keyboard 101 interacts with the security image recognition station host 102, the alarm device can receive a trigger signal from the image recognition program and transmit an alarm signal (such as a flashing indicator light or a buzzer) to alert security personnel. The image recognition program can detect abnormal conditions, triggering the alarm device to emit an alarm signal when an abnormal condition is detected.

[0048] Abnormal conditions may include but are not limited to: communication between the processor and the security inspection keyboard 101 is interrupted, or the time interval between the processor and the security inspection keyboard 101 transmitting signals exceeds a first preset time length, or the time interval between the previous and next images exceeds a second preset time length, the state of the display screen switches from a blank state to an image appearing, or it is recognized that the image contains prohibited items, etc.

[0049] Different abnormal conditions can produce different alarm signals, such as various combinations of alarm indicators and / or buzzers. For example, multiple LED lights of different colors can be used to display status and alarm information, while a buzzer can also emit alarm sounds of different frequencies.

[0050] When the communication between the processor and the security-specific keyboard 101 is interrupted, or the time interval between the processor and the security-specific keyboard 101 transmitting signals exceeds the first preset time length, an alarm signal is issued to remind the security personnel that there is an abnormality in the working status of the security-specific keyboard 101, and to remind the security personnel to pay attention and handle it in time.

[0051] When the time interval between the previous and next images exceeds a second preset time length, or the display screen switches from a blank state to an image display state, an alarm signal is issued. In this way, when no target passes through the security inspection equipment for a long time and a new target suddenly passes through the security inspection equipment, the security inspectors are reminded to concentrate on the security inspection image judgment to avoid missed inspections.

[0052] When the processor automatically identifies that the image contains prohibited items through image recognition, an alarm signal is triggered, which can remind the security personnel to promptly operate the first button 11 that cannot pass the security check, thereby assisting the security personnel in the security inspection and image judgment operation and improving the security inspection efficiency.

[0053] In this way, the security inspection image judgment can be assisted by sound and light reminders to avoid missed inspections and improve security inspection efficiency.
