DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] As Figures 1 to 5As shown in the figure, an administrative service system processing terminal includes a main cabinet 1. Accommodation cavities 2 are provided on each side end face of the main cabinet 1. Terminal components are assembled in each accommodation cavity 2. The terminal components include a first body 3 and a second body 4. The first body 3 and the second body 4 are respectively arranged on the left and right sides of the accommodation cavity 2. A first display screen 5, a first main control device and a first identity verification device are provided on the first body 3. A second display screen 6, a second main control device and a second identity verification device are provided on the second body 4. When the first display screen 5 and the second display screen 6 are in the initial positions, the first display screen 5 and the second display screen 6 are spliced to form a main display screen;

[0031] The first display screen 5 and the second display screen 6 select screens with a frame width ≤ 1.7 mm (such as a 0.88 mm ultra-narrow edge design), which can greatly reduce the physical black edge at the splicing part. And through the built-in system, pixel alignment and color consistency are adjusted to synchronize the screen display. At the same time, when merging the display, key information is avoided from being placed in the splicing seam area to achieve a visual seamless effect.

[0032] A support 7 is slidably assembled in the accommodation cavity 2. A telescopic cylinder is connected between the support 7 and the accommodation cavity 2. The telescopic cylinder is used to drive the support 7 to move back and forth. The first body 3 and the second body 4 are respectively slidably installed on the front left and right sides of the support 7. A power component is provided on the support 7. The power component is used to drive the first body 3 and the second body 4 to approach or move away from each other. Monitoring modules 8 are provided at the upper ends of each side end face of the main cabinet 1 to be used for detecting the flow of people. A control system is provided in the main cabinet 1. The control system is electrically connected to the monitoring module 8, the telescopic cylinder and the power component to be used for controlling the positions of the first body 3 and the second body 4 according to the flow of people. Slide rails 14 are provided on the upper and lower sides of the front end face of the support 7. A first moving seat 15 and a second moving seat 16 are respectively slidably assembled on both sides of the slide rails 14. The first body 3 and the second body 4 are respectively assembled on the first moving seat 15 and the second moving seat 16. Grooves 17 are provided at the right end of the first moving seat 15 and the left end of the second moving seat 16. Rack bars 18 are fixedly provided in the grooves 17 on both sides, and the rack bars 18 extend out of the grooves 17. The power component includes a motor. The motor is installed at the rear end of the support 7, and its output shaft penetrates and extends to the front side of the support 7. A gear 19 is provided on the output shaft of the motor. The gear 19 meshes and drives with the rack bars 18 on both sides;

[0033] When it is detected that there is a large flow of people and queuing occurs, the control system first issues a warning to signal the queuing crowd to retreat. After creating an expansion space, the telescopic cylinder drives the support 7 to move out of the accommodation cavity 2. Then, the motor drives the gear 19 to rotate. The counterclockwise rotation of the gear 19 drives the racks 18 on the upper and lower sides to move laterally, thereby driving the first body 3 and the second body 4 to move laterally. Eventually, they are quickly separated into two independent terminals, forming a service diversion channel, avoiding the congestion problem caused by the fixed layout of traditional terminals. And by moving the first body 3 and the second body 4 outward, there is enough clearance between the first body 3 and the second body 4, so that users on both sides will not be congested during operation, and at the same time, the privacy of users can be guaranteed;

[0034] Conversely, during the daily off-peak period, the first body 3 and the second body 4 are spliced into a large-screen single machine mode through reverse operation, reducing the floor area by more than 60%. And in the single machine mode, if a failure occurs in the first body 3 or the second body 4, it will immediately switch to the other body to work independently, and it can also maintain single machine operation during maintenance and upgrade, realizing zero interruption of services.

[0035] In this embodiment, a printing device 9 is provided in the middle of the lower side of the front end face of the support 7. A first storage cavity 10 and a second storage cavity adapted to both sides of the printing device 9 are respectively opened on the right side of the first body 3 and the left side of the second body 4. And the front ends of the first storage cavity 10 and the second storage cavity are respectively communicated with a first paper outlet 11 and a second paper outlet 12. When the first body 3 and the second body 4 are in the initial position, the first paper outlet 11 and the second paper outlet 12 are spliced and communicated; A conveying mechanism 13 is assembled on the front end face of the support 7, and the conveying mechanism 13 is arranged below the printing device 9. When the first body 3 and the second body 4 are in the initial position, the conveying mechanism 13 is located in the first paper outlet 11 and the second paper outlet 12. When the first body 3 and the second body 4 are in the separated position, both ends of the conveying mechanism 13 are respectively docked with the right side of the first paper outlet 11 and the left side of the second paper outlet 12;

[0036] When the first body 3 and the second body 4 are used in combination, the materials printed by the printing device 9 directly fall onto the conveying mechanism 13. At this time, the conveying mechanism 13 does not work, and users can directly take them out from the paper outlet formed by the first paper outlet 11 and the second paper outlet 12. And when the first body 3 and the second body 4 are separated and used as two independent terminals, after the materials printed by the printing device 9 fall onto the conveying mechanism 13, the control system sends a signal to the conveying mechanism 13. According to whether the material belongs to the user of the first body 3 or the user of the second body 4, the conveying mechanism 13 conveys to the left or to the right to send the material into the corresponding first paper outlet 11 or second paper outlet 12, thus preventing the problem of confusion of the materials printed when there are printing operations on both the first body 3 and the second body 4 at the same time;

[0037] In this embodiment, lead screws 20 are vertically arranged on the front end faces of the first moving seat 15 and the second moving seat 16. The first body 3 and the second body 4 are respectively slidably assembled on the first moving seat 15 and the second moving seat 16 and are threadedly connected to the corresponding lead screws 20. The lead screws 20 on both sides are respectively driven to rotate by two motors. By rotating the lead screws 20, the first body 3 or the second body 4 can be driven to move up and down, so as to meet the operation needs of users of different heights (such as children, wheelchair users or special groups), and reduce the operation threshold. When the first body 3 and the second body 4 are used in combination, the motors on both sides work synchronously to drive the first body 3 and the second body 4 to lift synchronously.

[0038] In this embodiment, a receiving groove 21 is formed at the top of the main body cabinet 1. A number of guiding components are arranged in the receiving groove 21. The guiding components include an unmanned aerial vehicle 22 and a parking garage 23. The parking garage 23 is installed in the receiving groove 21. The unmanned aerial vehicle 22 is remotely controlled by government service personnel for remote guidance. The parking garage 23 can be used to charge the unmanned aerial vehicle 22;

[0039] The unmanned aerial vehicle 22 is equipped with a camera and multiple different types of sensors, which can monitor the distribution of the flow of people in the government affairs hall in real time, analyze hot spots through algorithms, dynamically adjust the queuing path in front of the self-service terminal, reduce congestion, and the unmanned aerial vehicle 22 can quickly move between different floors or zones in the hall, and guide users to the corresponding terminals according to the business types (such as ID card application, social security query), reducing cross-regional chaos;

[0040] At the same time, compared with the traditional planar guidance, the unmanned aerial vehicle 22 can display a three-dimensional route through an aerial view to help users quickly locate the terminal position. When a user needs to take a number from the terminal and go to the corresponding window for manual processing, the unmanned aerial vehicle 22 can guide the user to the window, which is especially suitable for government affairs halls with complex layouts. At the same time, the unmanned aerial vehicle 22 can provide voice guidance for visually impaired persons or serve hearing-impaired persons through light indication, enhancing the barrier-free service ability.

[0041] In this embodiment, the first identity verification device includes a first image acquisition unit 24, a first reading unit 25 and a first document verification unit 26. The first image acquisition unit 24 is arranged in the middle of the upper side of the front end of the first body 3. The first reading unit 25 and the first document verification unit 26 are arranged on the left side of the front end of the first body 3; the second identity verification device includes a second image acquisition unit 27, a second reading unit 28 and a second document verification unit 29. The second image acquisition unit 27 is arranged in the middle of the upper side of the front end of the second body 4. The second reading unit 28 and the second document verification unit 29 are arranged on the right side of the front end of the second body 4; both the first reading unit 25 and the second reading unit 28 are used to identify and read two-dimensional codes, and the first document verification unit 26 and the second document verification unit 29 are used to identify and verify the user's document information;

[0042] When the first body 3 and the second body 4 are used in combination, the document verification units and reading units on both sides can be used, enabling left-handed or right-handed users to choose the most comfortable operating side, reducing misoperations caused by awkward postures. For wheelchair users or groups with hand disabilities, the bilateral design allows for flexible adjustment of the operating position, conforming to the concept of barrier-free services. Thus, when the terminals are used in combination, the document verification units and reading units on both sides will not be wasted and can both play their roles.

[0043] This embodiment further includes a data collection system, which includes a terminal collection module deployed in the above-mentioned processing terminal for real-time collection of business processing data, device status data, and user interaction logs; such as real-time recording of business processing information (such as form-filling content, document information), device operation status (such as a paper shortage prompt for the printing device 9), and user operation logs.

[0044] A data synchronization module, which adopts a dynamic timestamp marking mechanism to trigger data deduplication and merging operations when detecting business-related data among processing terminals; for example, when the masses handle the same business on different terminals (such as submitting materials on terminal A first and then supplementing materials on terminal B), the system automatically merges the complete materials to avoid duplicate submissions.

[0045] A data cleaning module for standardizing the data collected from each processing terminal; for example, unifying the dates collected from different terminals (such as 2025 / 03 / 11 and March 11, 2025) into a standard format, dynamically masking fields involving personal privacy, and intelligent error correction: discovering and correcting filling contradictions through semantic analysis.

[0046] A distributed storage module, which adopts a hot and cold data hierarchical architecture, stores real-time business data in a database, transfers historical archived data to an object storage repository, and establishes a secondary index based on the business type - time dimension.

[0047] For example: High-frequency data (business records in the recent 3 months) is stored in the fast access area (database) for real-time and quick query, and historical data (records over 1 year old) is transferred to the economical large-capacity storage area (object storage repository), and by establishing multi-dimensional retrieval tags, it supports combined query by business type (such as social security, provident fund) and time period.

[0048] A blockchain evidence storage module, which calculates the hash value of key business data and synchronizes it to the nodes of the government affairs alliance chain to generate an evidence storage certificate containing a timestamp, terminal number, and identity data; it can generate a unique identification code for key business data (such as approval results) and synchronize it to the government's dedicated blockchain network to ensure the authenticity of the original records can be verified during subsequent audits.

[0049] Visual analysis platform, used to provide a configurable dashboard for data map display, abnormal operation warning, and service efficiency analysis;

[0050] This visual analysis platform provides a visual dashboard for government administrators, including three core functions: Real-time service map: Displays the heat map of terminal usage in each area (such as the queuing situation in the government affairs center); Equipment health monitoring: Alerts equipment failures such as insufficient ink and network interruption; Efficiency analysis report: Counts the business handling efficiency in each period and indicates the areas where terminals need to be added.

[0051] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
