[0041] To help those skilled in the art better understand this solution, the following will clearly describe the technical solutions in the embodiments of this solution in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of this solution, not all of it. Based on the embodiments of this solution, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of this solution.

[0042] Throughout the specification, claims, and accompanying figures of this solution, the term "including" and any variations thereof mean "including, but not limited to," and are intended to cover non-exclusive inclusions and are not limited to the examples listed herein. Furthermore, the terms "first" and "second," etc., are used to distinguish between different objects, not to describe a specific order.

[0043] The following describes the implementation of the present disclosure in detail with reference to the accompanying drawings:

[0044] Figure 1 This is a structural diagram of a self-service terminal for visitor identity verification provided by the embodiment of the present disclosure. Figure 1 The visitor identity verification self-service terminal includes: a camera module, a camera rotation control module, a distance measurement module, a control module, a printing module and a first switch.

[0045] The control module is connected to the camera module, the printing module, the distance measurement module, and the first switch. The camera rotation control module is connected to the camera module via the first switch. The camera rotation control module is configured to control the camera rotation angle of the camera module. The camera module is configured to capture facial information of visitors.

[0046] The printing module is configured to print a visitor's identity verification certificate. The distance measurement module is configured to collect the visitor's location. The control module is configured to control the on / off state of the first switch based on the visitor's location and facial information.

[0047] In this embodiment, the camera module may include a high-resolution camera, connected to the control module via data transmission and control lines. It receives commands from the control module and transmits captured image data to the control module. The camera module is connected to the camera rotation control module via a first switch. When the first switch is closed, the camera rotation control module activates and controls the rotation of the camera in the camera module to achieve a suitable angle. The camera module can be mounted on the top or upper front of the terminal (center, left, or right) to achieve a suitable shooting angle.

[0048] The camera rotation control module may include a small motor, a transmission device (such as gears or belts), an angle sensor (such as a rotary encoder), and a control circuit. The control circuit receives control signals from the control module and converts them into motor drive signals. The control circuit may include signal amplification circuits, a pulse distributor (for stepper motors), or a motor driver (for DC motors). The small motor provides power, and the transmission device transmits the motor's power to the camera module, enabling the camera in the camera module to rotate. The angle sensor provides feedback on the camera module's rotation angle. The motor is connected to the camera module's base or housing via the transmission device, so that rotation of the motor drives the camera module. The angle sensor can be installed in a position that rotates synchronously with the camera module and is connected to the control module to transmit angle information. The camera rotation control module can be placed at the bottom of the camera module to facilitate space utilization and provide stable support, ensuring smoother rotation.

[0049] The distance measurement module can include an infrared sensor or an ultrasonic sensor. Infrared sensors measure distance by emitting and receiving infrared light, while ultrasonic sensors utilize the reflection of ultrasonic waves. The distance measurement module collects distance information between the visitor and the terminal. Connected to the control module, the distance measurement module transmits the measured distance data to the control module. The distance measurement module can be located on the front panel of the terminal, with multiple sensors arranged in an array to comprehensively cover the detection range in different directions.

[0050] The first switch may be an electronic relay switch or a MOSFET switch, etc.

[0051] The printing module may include a print head (such as a thermal or dot matrix print head), a paper feed mechanism, an ink cartridge (for inkjet printing) or a ribbon (for dot matrix printing), and a paper tray. Following instructions from the control module, the printing module prints the visitor's identity verification information onto paper according to a template, creating a certificate. The printing module can be located at the bottom or side of the terminal, with a paper outlet for convenient removal of printed certificates and ample space for paper and related printing supplies.

[0052] For example, given that scenic spots often encounter visitors forgetting to bring their IDs or other necessary documents, this embodiment can help visitors generate temporary identity verification documents. Visitors can then use these documents to participate in various scenic spot activities. For example, some scenic spot activities may have age or height restrictions, while others may offer preferential policies for special groups. In these cases, visitors can present their identity verification documents for verification. This embodiment can also provide self-service printing services for visitors.

[0053] Furthermore, considering the large number of tourists queuing at scenic spots, especially children, the elderly, or special groups, who may find it inconvenient or impossible to align their faces with the camera when queuing for identity verification or printing identity verification certificates due to height or other physical reasons, the camera may scan other tourists behind them, resulting in facial recognition errors, reduced work efficiency, and a poor visitor experience. This embodiment provides a mode in which the ranging module, camera module, control module, and camera rotation control module work in coordination.

[0054] Specifically, when a visitor undergoes facial recognition, the camera module captures the facial image and uses it to calculate the visitor's position in the image. Simultaneously, the distance measurement module measures the visitor's position. The control module receives both positions and, if the two positions are inconsistent and the difference exceeds a preset distance difference threshold, determines that the visitor is incorrect (i.e., the face scanned by the camera module is not the visitor undergoing identity verification).

[0055] At this point, the control module can control the first switch to close, activating the camera rotation control module. The control module can determine the visitor's height and position based on the multiple distances measured by the distance measurement module. Based on this height and position information, it controls and calculates the rotation angle, generates a corresponding control signal, and sends it to the camera rotation control module. Based on this control signal, the camera rotation control module controls the camera module to rotate to the correct angle. The camera module then captures facial image information again for identity verification.

[0056] From the above, it can be concluded that, on the one hand, this embodiment can flexibly adjust the shooting angle through the coordinated work of the high-resolution camera and the camera rotation control module, ensuring that facial information can be accurately captured in front of tourists of different heights and body shapes, effectively avoiding facial recognition errors, and improving work efficiency and tourist experience.

[0057] On the other hand, the introduction of the distance measurement module further enhances the intelligence of this embodiment. The distance measurement module can measure the distance between the visitor and the terminal in real time, providing the control module with accurate location information, helping to quickly determine and correct potential errors in facial recognition, thereby ensuring the accuracy of identity verification.

[0058] Furthermore, the self-service terminal's printing module provides visitors with a convenient self-printing service, quickly generating identity verification documents without manual intervention. This not only saves labor costs but also improves service efficiency, making it easier for visitors to participate in scenic area activities.

[0059] In summary, this embodiment realizes efficient and accurate identity verification and certificate printing services through intelligent and automated design, provides strong technical support for scenic area management, and also brings a more convenient and comfortable experience to tourists.

[0060] In one embodiment of the present disclosure, the ranging module includes:

[0061] Infrared sensor array.

[0062] The infrared sensor array is connected to the control module, and the infrared sensor array is configured to collect the location of the visitor.

[0063] In this embodiment, the infrared sensor array consists of multiple infrared sensors. Each infrared sensor includes an infrared transmitter and an infrared receiver. The transmitter emits infrared light, and the receiver receives reflected infrared light. These infrared sensors are arranged in a regular pattern within the array, forming a two-dimensional or three-dimensional detection layout. The infrared sensors can be installed on the front or periphery of the terminal, or can be embedded flat on the terminal surface. The installation height and spacing of the infrared sensors are determined based on the overall terminal design and the average height of visitors, ensuring accurate detection of visitors of varying heights.

[0064] For example, the infrared sensor's infrared transmitter continuously emits infrared light. When a visitor enters the detection range, the infrared light hits the visitor's body, reflects, and is received by the infrared receiver. The distance between the visitor and the sensor is calculated based on the time difference between the emission and reception of the infrared light or the change in the intensity of the reflected light. Data from multiple sensors is aggregated and sent to the control module to determine the visitor's location.

[0065] This embodiment uses infrared sensors to accurately determine the location of visitors, providing reliable data support for identity verification, and further improving the intelligence level of this embodiment.

[0066] like Figure 2 As shown, in one embodiment of the present disclosure, the visitor identity verification self-service terminal further includes:

[0067] Power management module.

[0068] The power management module is connected to the control module and is configured to control the output power of the power supply, which is used to power the camera module, the camera rotation control module, the ranging module, the control module and the printing module.

[0069] In this embodiment, the power management module may include a voltage regulation circuit, a current detection circuit, a power control chip, and a microcontroller. The voltage regulation circuit may utilize a DC-DC converter or a linear voltage regulator circuit to adjust the output voltage. The current detection circuit is used to monitor the current consumption of each module in real time. Based on current and voltage information, the power control chip, coordinated by the microcontroller, precisely controls the output power. The power management module can be installed on a circuit board within the self-service terminal, near the power input interface. The power management module should be kept a certain distance from other heat-generating components to prevent overheating from affecting its performance.

[0070] For example, during operation, the power management module first receives power input from the power supply. A current detection circuit continuously monitors the current usage of each module (such as the camera module and the ranging module) and feeds this information back to the power control chip. The microcontroller then issues instructions to the power control chip based on a preset power allocation strategy (which is determined based on the operating status of each module, such as standby or active). The power control chip adjusts the output voltage via a voltage regulation circuit, thereby controlling the power output of the power supply and ensuring a stable and appropriate power supply to each module. For example, when the printing module requires higher power during operation, the power management module can increase the output power appropriately. When certain modules are in standby mode, the power supply to these modules is reduced to conserve energy.

[0071] The power management module in this embodiment ensures stable operation and energy conservation across all modules by precisely controlling output power. It monitors current consumption in real time and intelligently adjusts voltage output, ensuring that modules like the camera, ranging, and printer receive appropriate power under different operating conditions. This embodiment not only improves terminal operational efficiency but also effectively reduces energy consumption, extending the device's lifespan, providing visitors with more reliable and efficient identity verification services. It also embodies a green and environmentally friendly design philosophy.

[0072] like Figure 2 As shown, in one embodiment of the present disclosure, the visitor identity verification self-service terminal further includes:

[0073] Paper capacity detection module.

[0074] The paper capacity detection module is connected to the control module.

[0075] The paper capacity detection module is configured to detect the paper capacity.

[0076] In this embodiment, the paper capacity detection module may include a photoelectric sensor, a mechanical microswitch, or an ultrasonic sensor. The photoelectric sensor determines the amount of paper by detecting the degree to which the paper blocks light. The mechanical microswitch senses the presence or amount of paper by being triggered by the paper. The ultrasonic sensor uses the principle of ultrasonic reflection to determine the paper capacity based on changes in the reflected wave.

[0077] For example, photoelectric sensors can be installed on the sides or bottom of the paper tray to detect the paper height by emitting and receiving light. Mechanical micro switches can be installed at the bottom of the paper tray or at key locations in the paper path, triggering when the paper reaches a certain level. Ultrasonic sensors can be installed above the printing module to emit ultrasonic waves towards the paper stack.

[0078] For example, during operation, the photoelectric sensor converts detected paper-related information (such as light obstruction, trigger signals, and ultrasonic reflection time) into electrical signals and transmits them to the control module. The control module calculates the remaining paper capacity based on these signals and triggers an alarm or prompt when the paper capacity falls below a set threshold.

[0079] This embodiment monitors the remaining paper capacity in real time to ensure timely replenishment, avoid printing interruptions, and improve service efficiency. Furthermore, automatic alarms or prompts when paper is low reduce the burden of manual checks and enhance the user experience. This embodiment achieves convenience and practicality, providing visitors with a smoother and more efficient identity verification service.

[0080] like Figure 2 As shown, in one embodiment of the present disclosure, the printing module includes:

[0081] A second switch, a first printing unit, and a second printing unit.

[0082] The second switch is connected to the control module, the first printing unit and the second printing unit respectively.

[0083] The first printing unit is disposed above the second printing unit.

[0084] In this embodiment, the second switch is an electronic multiplexing switch or a relay combination, and the second switch can selectively connect the circuit of the first printing unit or the second printing unit according to the control signal.

[0085] The first printing unit or the second printing unit may include a printing pin, a ribbon, a paper feed motor, etc. The first printing unit and the second printing unit are similar in structure, but have different printing parameters (such as resolution, speed, number of printable layers, etc.) and setting locations.

[0086] The printing module is installed in a print compartment located at the bottom or side of the self-service terminal. The first printing unit is located at the top, and the second printing unit is located at the bottom. Both units are mechanically secured within the compartment, and their respective circuits are connected to a second switch and a power source. A paper outlet is provided for each of the first and second printing units, located at the front or bottom of the print compartment.

[0087] The control module controls the selection of the first printing unit or the second printing unit according to the location of the visitor to print and output the certificate document for the visitor.

[0088] For example, the second switch is connected to the first printing unit by default, and when it is detected that the visitor is in a lower position and the camera rotation control module is in the on state, the second switch is controlled to connect to the second printing unit to facilitate the visitor to take it.

[0089] The dual-printing unit design of the printing module in this embodiment enhances the flexibility and user experience of the visitor identity verification self-service terminal by intelligently selecting the printing position. Automatically switching the printing unit based on the visitor's location ensures easy access to printed documents, reducing inconvenience and improving service efficiency and satisfaction.

[0090] like Figure 2 As shown, in one embodiment of the present disclosure, the visitor identity verification self-service terminal further includes:

[0091] Voice module and keyboard input module.

[0092] The voice module and the keyboard input module are both connected to the control module.

[0093] The voice module is configured to provide voice prompts, and the keyboard input module is configured to receive input information.

[0094] In this embodiment, the voice module includes a microphone and a speaker. These are mounted on the top or front of the self-service terminal in a prominent location to ensure effective sound transmission. The keyboard input module can be a metal keyboard, a membrane keyboard, or a capacitive touch keyboard. The keyboard includes numeric keys, alphabetic keys, and function keys to meet various input requirements. The keyboard input module is mounted on the front of the self-service terminal at a height convenient for visitors, such as below or next to the display screen.

[0095] For example, the control module sends the required text message to the voice module, which then emits a sound through the speaker, thereby conveying operational prompts, guidance, or warnings to visitors. For example, when a visitor approaches the terminal, the voice module may prompt, "Welcome, please stand in a suitable position." Visitors can use the keyboard input module to enter their identity information, verification codes, and other information. This is used to assist with identity verification and other related operations if the network system cannot retrieve the visitor's identity information.

[0096] This embodiment significantly enhances the convenience and diversity of human-computer interaction by integrating a voice module and a keyboard input module. The intuitive and easy-to-understand voice prompts and the flexible and accurate keyboard input together enhance the user experience, ensure the efficiency and accuracy of identity verification, and meet the needs of different scenarios.

[0097] like Figure 2 and Figure 3 As shown, in one embodiment of the present disclosure, the visitor identity verification self-service terminal further includes:

[0098] Alarm module and display module.

[0099] The alarm module and the display module are both connected to the control module.

[0100] The display module includes:

[0101] Static display screen 1, face recognition display screen 2 and operation display screen 3.

[0102] The static display screen 1, the face recognition display screen 2 and the operation display screen 3 are all connected to the control module.

[0103] In this embodiment, the alarm module includes an audible and visual alarm, such as a light emitting diode (LED) and a buzzer. The LED is used to emit a flashing light signal, and the buzzer generates an alarm sound.

[0104] The static display screen 1 can be a liquid crystal display screen or an electronic ink screen, and is used to display fixed information, such as terminal instructions, welcome slogans, etc. The static display screen 1 is installed above the front or side of the terminal.

[0105] The facial recognition display 2 is a high-resolution LCD screen that displays facial images captured by the camera, facilitating posture adjustments for visitors. It is located in the upper middle of the front of the terminal, near the camera module.

[0106] The operation display screen 3 is a liquid crystal display screen, which is used to guide tourists to complete identity verification related operations, such as inputting information, confirming, etc. It is installed in the middle of the front of the terminal for easy operation by tourists.

[0107] For example, when the control module detects an abnormal situation (such as multiple identity verification failures or equipment malfunction), it sends a signal to the alarm module, causing the LED to flash and the buzzer to sound, alerting staff or visitors. The control module can send different types of information to corresponding displays. For static display 1, information is pre-stored and continuously displayed; facial recognition display 2 receives and displays image data captured by the camera module; and operation display 3 displays an interactive interface based on the visitor's operation steps, guiding visitors through the identity verification process.

[0108] This embodiment realizes diversified information display and instant alarm of abnormal situations by integrating alarm modules and multi-type display screens, effectively improving user experience and security, ensuring the smooth progress of identity verification process, and enhancing the reliability and maintainability of the equipment.

[0109] The above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them. Although the present disclosure has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
