[0026] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. It should be understood, however, that the description which follows is merely exemplary and is not intended to limit the scope of the present disclosure. In the following detailed description of embodiments of the present disclosure, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure. However, it would be apparent to one skilled in the art that one or more embodiments of the present disclosure can be practiced without these specific details. In other instances, well-known structures and functions have not been described in detail in order to avoid obscuring aspects of the present disclosure.

[0027] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the present disclosure. As used herein, the term "includes" and / or "including", as well as

[0028] After the inventors' in-depth research on the artificial judgment scene in the security inspection field, it is found that the timeliness requirements of different function keys in the security inspection scene are different. Specifically, in the short process that the target (such as luggage or personnel to be inspected) passes through the security inspection equipment and leaves the security inspection equipment, the security inspection personnel need to quickly and accurately judge whether the target passes the security inspection according to the images collected by the security inspection equipment, so the timeliness of the keys used in this process is very high, mainly including two categories: one category is the keys for judging whether the target passes the security inspection, and the other category is the image processing function keys used in the process of assisting accurate judgment of images (such as zooming in, zooming out, brightening, etc.). As for other functions, such as inputting account name and password when logging in to the security inspection system at the beginning of each security inspection period, uploading records or data regularly or irregularly, etc., the timeliness and frequency of use are relatively low.

[0029] Therefore, the inventors consider that the function keys with relatively high timeliness requirements in the security inspection scene can be highlighted on the keyboard (for example, highlighted by size, layout, color, shape or touch feeling, etc.), and the functions with relatively low timeliness requirements (and also relatively low frequency) can be concentrated by triggering the shortcut keys of the software pad. In this way, the high-frequency and high-timeliness keys in the security inspection scene are highlighted, which facilitates the use of security inspection personnel and reduces the learning cost of security inspection personnel. Moreover, when the shortcut keys of the software pad are triggered to concentrate the key functions, the number of keys can also be reduced, which is conducive to reducing the size of the keyboard. In addition, considering that there may be a special demand or some demand that is difficult to determine in advance, some self-defined keys can also be reserved for users to set according to actual conditions.

[0030] Based on this, the embodiments of the present disclosure provide a security inspection special keyboard and a security inspection system applying the security inspection special keyboard. The embodiments will be described in detail below in combination with FIGS. 1-5.

[0031] FIG. 1 schematically shows a system architecture 100 of a security inspection system according to an embodiment of the present disclosure.

[0032] As shown in FIG. 1, the system architecture 100 can include a security inspection special keyboard 101, a security inspection judgment station host 102 and a security inspection judgment station display screen 103.

[0033] The security inspection special keyboard 101 is a security inspection special keyboard of the embodiments of the present disclosure.

[0034] The security check judgment station host 102 is internally provided with a processor. The security check special keyboard 101 is in communication connection with the security check judgment station host 102, so that the security check special keyboard 101 can communicate with the processor. The security check special keyboard 101 and the security check judgment station host 102 can be in wired connection or wireless connection. When the security check special keyboard 101 and the security check judgment station host 102 are in wired connection (such as through USB interface connection), the security check special keyboard 101 can be set as passive power supply, and the security check judgment station host 102 supplies power for the security check special keyboard 101, realizing plug and play, which is conducive to reducing the size of the keyboard.

[0035] The security check judgment station display screen 103 is in communication connection with the security check judgment station host 102.

[0036] The security check judgment station host 102 is installed and runs a judgment program software adapted to the security check special keyboard 101. The security check judgment station host 102 realizes simple man-machine interaction with the user through the security check judgment station display screen 103 and the security check special keyboard 101.

[0037] FIG. 2 schematically shows a structural schematic diagram of an embodiment one of the security check special keyboard 101 according to the embodiment of the present disclosure. FIG. 3 schematically shows a structural schematic diagram of an embodiment two of the security check special keyboard 101 according to the embodiment of the present disclosure.

[0038] The structure of the security check special keyboard 101 according to the embodiment of the present disclosure is described in detail below with reference to the embodiments of FIG. 2 and FIG. 3.

[0039] Specifically, the security check special keyboard 101 can at least include N first keys 11, M second keys 12 and one third key 13. Wherein, the value of N is 1 or 2, and the value of M is a positive integer not more than 10.

[0040] The first key 11 is used to judge whether the target passes the security check in the security check process. In the security check special keyboard 101, the number of the first key 11 is 1 or 2, so that one or two first keys 11 can be set to judge whether the target passes the security check according to the operation requirements in different security check scenes.

[0041] The second keys 12 are used to process the collected image of the target in the security check process. For example, in FIG. 3, the second key 12 containing the symbol "+" can be used to enlarge the image, the second key 12 containing the symbol "-" can be used to reduce the image, the second key 12 containing the character "ESC" can be used to undo the previous image processing operation, and the second keys 12 containing the symbols "F1", "F2", and "F3" respectively can be customized by the user for image processing functions, which can be freely defined by the security personnel according to their preferences to achieve different functional effects. In the embodiments of the present disclosure, the number M of the second keys 12 is a positive integer not greater than 10, which can limit the number of keys, on the one hand to reduce the learning cost, and on the other hand to reduce the size of the keyboard.

[0042] The third keys 13 are used to trigger the soft keyboard. Specifically, when the third keys 13 are pressed, a signal triggering the soft keyboard is sent to the security check station host 102 to trigger the display of the soft keyboard on the security check station display screen 103.

[0043] In the embodiments of the present disclosure, the size of the first keys 11 is greater than the size of the second keys 12, and the size of the second keys 12 is not less than the size of the third keys 13. In this way, at least the size of the first keys 11 is the largest in the keyboard and is greater than the other two types of keys, so that the first keys 11 with high time efficiency requirements can be highlighted, and the security personnel can quickly and efficiently master the first keys 11 and operate the first keys 11 with high accuracy. This greatly facilitates the efficiency of the security personnel in image judgment.

[0044] In some embodiments, the size of all second keys 12 can be set to be greater than the size of the third keys 13 (as shown in FIG. 2). In this way, the sizes of the keys in the security-specific keyboard 101 can be divided into three levels of large, medium, and small, and the medium-sized keys are all image processing function keys, which facilitates the security personnel to quickly and accurately distinguish the types of keys according to the size of the keys, saves learning cost, and facilitates blind typing.

[0045] In other embodiments, some of the second keys 12 can be set to be larger than the third keys 13, and the other keys can be the same size as the third keys 13 (as shown in FIG. 3). Specifically, which second keys 12 are selected to be larger can be set according to whether the keys are frequently used or the layout of the keys. In this way, by setting different sizes of the second keys 12 with different functions, a part of the image processing keys can be distinguished, which is convenient for users to learn and blind type, and is also conducive to reducing the overall size of the keyboard.

[0046] According to some embodiments of the present disclosure, the security inspection special keyboard 101 can further comprise at least one fourth key 14. The fourth key 14 can be a reserved user-defined key. For example, in some security inspection scenarios, it is required to issue a "high risk" operation when it is determined that the target is a high-risk item. The fourth key 14 can be configured as a "high risk" function.

[0047] When the fourth key 14 has the same size as the third key 13, the user can quickly distinguish the fourth key 14 from the third key 13 through the key layout setting of the fourth key 14 and the third key 13. When the fourth key 14 is smaller than the third key 13, it is convenient for the user to type blindly, improves the accuracy of blind typing, and also reduces the size of the key.

[0048] It can be understood that the embodiment of FIG. 2 and FIG. 3 only contains one fourth key 14 as an example. In practice, several fourth keys 14 can be reserved, and then matched with the image recognition program software adapted to the security inspection special keyboard 101, to provide a certain autonomy and flexibility for the user. Of course, in some embodiments, in order to miniaturize the security inspection special keyboard 101 as much as possible while meeting the needs of security inspection scenarios, the number of keys on the security inspection special keyboard 101 can be limited to no more than 10. In this way, the number of keys that the security inspection personnel need to learn and master is reduced, and the floor space can be reduced. In the case where the space of the passenger security inspection channel and the like is very compact and limited, it is possible to reduce the size of the image recognition workbench, thereby reducing the floor space of the image recognition workbench and releasing more security inspection space.

[0049] As previously described, the number of first keys 11 in the security inspection special keyboard 101 can be one or two.

[0050] Specifically, the number of first keys 11 in the security inspection special keyboard 101 is one, as shown in FIG. 2. Such a security inspection special keyboard 101 can be applicable to the following situations. For example, in some security inspection scenarios, the security inspector does not need to perform any operation when the target passes the security inspection, but needs to press the first key 11 when the target does not pass the security inspection to indicate that the target needs to be checked in the box. For another example, different operation modes of the first key 11 can be set in the image recognition program software adapted to the security inspection special keyboard 101 to trigger user instructions for the target passing the security inspection and the target not passing the security inspection, respectively. For example, single click can represent the target passing the security inspection, and double click, continuous multiple clicks, or long press can represent the target not passing the security inspection.

[0051] An embodiment of the security-specific keyboard 101 with two first keys 11 is shown in FIG. 3. In this embodiment, one of the two first keys 11 can be used for passing the target through the security check (e.g., the left key with a symbol "X" marked on it), and the other one can be used for not passing the target through the security check (e.g., the right key with a symbol "V" marked on it). In this way, one first key 11 is fixed with one function option. In some embodiments, the two first keys 11 can be set with different colors. For example, one of the two first keys 11 can be set with a green surface, and the other one can be set with a red surface. In this way, the security officer can use the color of the keys to assist the accuracy of the blind typing, and the color of the keys can be visually distinguished. In other embodiments, the two first keys 11 can be set with different touch feelings. For example, the two first keys 11 can be set with different surface roughness, or only one of the first keys 11 can be set with a touch mark (e.g., a protrusion), or the two first keys 11 can be set with protruding symbols "X" and "V" respectively, or the two first keys 11 can be set with different outline shapes (e.g., one with sharp corners and the other with rounded corners), etc.

[0052] Continuing to refer to FIG. 3. In the case of two first keys 11, the two first keys 11 can be set in the first area, and the M second keys 12 can be set in the second area, where the second area and the first area do not overlap. In this way, the function categories of the keys can be divided by a certain degree of isolation between the first keys 11 and the second keys 12 in the layout, so as to save the learning cost of the user for the keys. Further, the third key 13 can also be set in the first area between the two first keys 11, so as to realize the symmetrical arrangement of the first keys 11 and the aesthetic appearance of the keys in the keyboard. In addition, in some embodiments, the two first keys 11 can be arranged side by side in the first area, where the area between the side away from each other of the two first keys 11 and the edge of the security-specific keyboard 101 is the frame of the security-specific keyboard 101. In this way, the security-specific keyboard 101 is convenient for the user to hold with one hand, and the two first keys 11 are convenient for the user to operate with two fingers alternately.

[0053] According to an embodiment of the present disclosure, each of the M second keys 12 corresponds to one or more operation functions. The operation functions corresponding to the M second keys 12 include, but are not limited to, operations such as enlarging an image, reducing an image, flipping an image, brightening, dimming, adjusting contrast, sharpening, and the like. When one second key 12 corresponds to multiple operation functions, the operation modes of the second keys corresponding to different operation functions are different. For example, different operation functions can be distinguished by single click, double click, triple click, or long press on the same second key 12. For example, for the second key 12 containing the symbol "+" in FIG. 3, when single clicked, it can indicate enlarging an image by a predetermined multiple, and when long pressed, it can indicate continuously enlarging an image, which is more in line with the operation habits in image processing. In this way, the security personnel can single-click a single key to quickly perform image processing and submit a security conclusion, or continuously press the key to achieve a gradual and continuous image effect.

[0054] According to some other embodiments of the present disclosure, the security-specific keyboard 101 can further include an alarm device, which can include at least one alarm indicator 15 and / or a buzzer, for example. The buzzer can be arranged inside the security-specific keyboard 101. The alarm device can receive a trigger signal of the image judgment program when the security-specific keyboard 101 interacts with the security image judgment station host 102, send an alarm signal (such as flashing of the indicator or buzzing), and prompt the security personnel.

[0055] FIG. 4 schematically shows an operation flow diagram of a processor in a security system according to an embodiment of the present disclosure.

[0056] In combination with FIGS. 1 and 4, the operation flow of the processor in the security system according to the embodiment of the present disclosure can include operation S401 to operation S402, wherein the processor is arranged in the security image judgment station host 102.

[0057] In operation S401, the user input transmitted by the security-specific keyboard 101 is received.

[0058] In operation S402, the processor runs the image judgment program adapted to the security-specific keyboard 101 to achieve: in response to receiving the user input transmitted by the security-specific keyboard 101, performing the function corresponding to the user input.

[0059] Specifically, in the process of passing the target through the security check, the corresponding operation of the security personnel on the first button 11 or the second button 12 (or the fourth button 14) can be received in operation S401, so as to quickly judge whether the target being detected passes the security check. In other cases where the time effectiveness requirement is not high, the operation of the security personnel on the third button 13 can be received in operation S401, and the software panel is called out on the security judgment station display screen 103 to help the security personnel complete the corresponding operation. In this way, by simplifying the keyboard keys, the key function with low time effectiveness requirement is "concentrated" on the third button 13, which not only ensures the security check demand, but also simplifies the keys, is convenient to operate, and can support more non-ordinary and personalized functions in combination with the software function, and has considerable flexibility.

[0060] Moreover, due to the setting of the first button 11 and the second button 12 with high time effectiveness requirement in the security special keyboard 101, combined with some touch feeling discrimination, layout setting, color prompt, etc., the security personnel can accurately and quickly complete the operation without looking at the keyboard, which makes the security personnel more focused on the display image on the security judgment station display screen 103 in the process of pressing the keys, reduces the missed detection probability, and improves the security judgment efficiency.

[0061] FIG. 5 schematically shows an operation flowchart of a processor in a security system according to another embodiment of the present disclosure.

[0062] In combination with FIG. 1 and FIG. 5, the operation flowchart of the processor in the security system of the present embodiment can further include operation S501 to operation S502, wherein the processor is arranged in the security judgment station host 102.

[0063] In operation S501, the image collected in the security process is displayed.

[0064] In operation S502, the abnormal state is detected. Operation S501 and operation S502 can also be executed in parallel.

[0065] In operation S503, the alarm device on the security special keyboard 101 is triggered to send an alarm signal in response to the detection of the abnormal state. For example, the alarm indicator light is triggered to light (or flash), or the buzzer is triggered to send a buzzing sound.

[0066] The abnormal state can include but is not limited to: the communication between the processor and the security special keyboard 101 is interrupted, the time interval of the signal transmission between the processor and the security special keyboard 101 exceeds the first preset time length, the time interval of the front and rear two images exceeds the second preset time length, the state of the display screen is switched from blank state to image appearance, or the image contains contraband, etc.

[0067] Different abnormal states, the alarm signal sent by the alarm device can be different, for example, it can be various combinations of alarm forms such as alarm indicator light and / or buzzer. For example, the state, alarm, etc. information can be displayed through multiple LED lights of different colors, and at the same time, different frequency alarm sounds can be emitted by the buzzer, etc.

[0068] When the processor is interrupted in communication with the security special keyboard 101, or the time interval of the processor transmitting signals with the security special keyboard 101 exceeds the first preset length of time, an alarm signal is sent, which can prompt the security personnel that the working state of the security special keyboard 101 is abnormal, reminding the security personnel to pay attention and handle in time.

[0069] When the time interval of the current and the next two images exceeds the second preset length of time, or the state of the display screen switches from blank state to image appearance, an alarm signal is sent, which can remind the security personnel to pay attention to the security judgment when a new target suddenly passes through the security device after a long period of time without any target passing through the security device.

[0070] When the processor automatically identifies that the image contains contraband through image recognition, an alarm signal is triggered, which can remind the security personnel to operate the first button 11 that cannot pass through the security device in time, thereby assisting the security personnel in security judgment operation and improving the security efficiency.

[0071] In this way, the security judgment can be assisted through the sound and light reminding mode, avoiding missed detection and improving the security efficiency.
