Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent medical systems, devices for use with power supplies, and the like, and in particular to a self-service terminal that can autonomously select payment. BACKGROUND

[0002] Medical institutions generally deploy self-service terminals for outpatient and examination after taking pictures / reports to share the pressure of manual window and shorten the waiting time of patients. The existing terminals interact with the hospital information system (HIS), the radiology information system (RIS), and the picture archiving and communication system (PACS) to complete identity verification, fee settlement, report or film query and printing and other processes. However, with the diversification of payment methods, the parallelization of printing media (paper reports and image films), and the increasing customization needs of different hospitals for certificate card systems and payment strategies, the traditional terminal exposes many deficiencies in interaction arrangement, task scheduling, and hardware openness.

[0003] First, in the payment-printing interactive path, existing devices usually preset a single payment method (e.g., only supporting code scanning or only supporting card swiping) or force payment and printing to be in a fixed order, lacking a mechanism for users to choose card swiping printing or code scanning printing independently. Once the payment channel is congested, the two-dimensional code times out, or the card fails to be issued, the user often needs to exit and start over, resulting in process interruption and experience degradation. Second, report printing and film printing belong to two types of media, two sets of drivers, and two hardware channels. Existing technologies generally separate them into independent processes or independent devices, making it difficult to achieve integrated selection and process prompts for "report only" and "report + film simultaneous printing" in the same UI. This can lead to inconsistent states such as "payment has been made, but only part of the media is released for printing," which can further trigger manual intervention and repeated fee disputes. Third, the state visualization capability of existing terminals is weak: most systems only provide a general "processing / please wait later." When the printer runs out of paper, the user-side UI often does not perceive it, causing repeated operations in front of the device, resource occupation, and congestion. In addition, in terms of hardware layout and human-machine engineering, traditional terminals lack consideration for the spatial relationship between interactive display, card reading, paper output, and film output: the card reading area and the film output are scattered or obstructed, and users can easily make mistakes in the operation position in a crowded environment. The report and film outputs are independent but not clearly prompted, often causing problems such as mistaken, missed, or chaotic order. For hospital scenarios that emphasize report and film taking together, existing terminals lack targeted structure and interactive guidance. In terms of certificate card compatibility and customization, various hospitals coexist with bank magnetic stripe cards / IC cards, social security cards, identity cards, hospital treatment cards, and other media. The card readers of existing terminals are mostly fixed models and interfaces, making it difficult to tailor or combine according to hospital needs. Once the certificate card system is adjusted or new media are added, it often involves replacing the entire machine or major modifications, increasing maintenance costs and downtime risks. In terms of system steady-state operation and maintainability, existing terminals rarely provide user-oriented consumable visibility windows or intuitive prompts, leading to frequent failures due to insufficient paper consumables. The fee verification, order backtracking, and reprinting process after printing failure relies on manual window coordination, which not only increases the burden on the window but also undermines the value of self-service terminals.

[0004] In summary, the prior art faces technical problems at least including: ① independent selection and seamless switching arrangement of multiple payment channels; ② joint printing task scheduling and unified UI process prompting of report and film dual media; ③ synchronization of device real state (including paper consumables) and front-end interaction state; ④ human-machine layout optimization of card reading / code scanning, paper output / film output to reduce misoperation and congestion; ⑤ on-demand customization of card reader module and compatibility with multiple card systems. Therefore, there is an urgent need for a self-service terminal scheme capable of realizing independent selection of payment paths by users, unified interactive arrangement of report printing and simultaneous printing of report films, and providing whole-process state prompts, with customizable card reader modules, support for multiple types of card interfaces, and visual and maintainable design for users and maintenance parties, to improve the success rate and user experience of self-service printing in medical scenarios, and reduce manual intervention and operation and maintenance costs.

Obviously, the described embodiments are only a part of the embodiments of the application, not all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor should belong to the scope of protection of the application.

[0024] Referring to Figs. 1-3 , the embodiment of the application provides a self-service terminal capable of autonomous payment selection, comprising:

[0025] A terminal host is arranged inside the shell of the terminal body 1, which includes a report printing functional area 10, a film printing functional area 11, an interactive display area 12, and a card reading area 13; the report printing functional area 10 and the interactive display area 12 are arranged side by side above the film printing functional area 11, the card reading area 13 is arranged on the side of the film printing functional area 11, and the bottom of the interactive display area 12 is provided with a code scanning port 14;

[0026] A printing and payment interactive screen 2 is arranged in the interactive display area 12, which displays the UI interface of the self-service printing system, the first page of the UI interface displays a selection prompt for self-payment printing, and the self-payment printing includes card printing and code scanning printing; when card swiping or code scanning triggers a printing request, the UI interface displays a printing option page, which includes a report printing option and a report and film simultaneous printing option; when the report printing option is triggered, the UI interface displays a printing process interface to prompt the printing process and status; when the report and film simultaneous printing option is triggered, the UI interface displays a code scanning payment interface, and after the code scanning payment is completed, the UI interface displays a printing process interface to prompt the printing process and status.

[0027] A report printing module 3 is arranged in the report printing functional area 10, which includes a report printer, a report outlet 30, and a consumable observation window 31; the report printer is assembled inside the shell of the terminal body 1, the report outlet 30 penetrates the shell of the terminal body 1 to form and communicate with the paper outlet of the report printer, and the consumable observation window 31 is located below the report outlet 30 to keep the consumable paper of the report printer in a non-shielding visible state.

[0028] A film printing module 4 is arranged in the film printing functional area 11, which includes a film printer and a film outlet 40; the film printer is assembled inside the shell of the terminal body 1, and the film outlet 40 penetrates the shell of the terminal body 1 to form and communicate with the film outlet of the film printer.

[0029] A customized card reader is assembled in the card reading area 13 in the form of an independent module, which provides at least one of a bank magnetic stripe card, a social security card, an ID card, and a hospital treatment card according to customized requirements.

[0030] In the embodiment, the terminal host is provided with a report printing function area 10, a film printing function area 11, an interactive display area 12 and a card reading area 13, and the report printing function area 10 and the interactive display area 12 are arranged side by side above the film printing function area 11, and a code scanning port 14 is arranged at the bottom of the interactive display area 12; the printing payment interactive screen 2 provides self-payment printing on the first page and contains two paths of card swiping printing and code scanning printing; after the card swiping or code scanning triggers the printing request, the UI displays the printing option page and selects and processes between the report printing option and the report film simultaneous printing option; the report printing module 3 includes a report printer, a report outlet 30 and a consumable observation window 31; the film printing module 4 includes a film printer and a film outlet 40; the customized card reader provides at least one card reading interface of a bank magnetic stripe card, a social security card, an ID card and a medical card in the form of an independent module, which can solve the technical problems of single payment path, difficult unified arrangement of report and film separation process, invisible state, easy confusion of taking, poor card compatibility and high maintenance cost of the self-service terminal: first, the double-path card swiping and code scanning entrance avoids the interruption of the whole process caused by single-channel congestion or timeout; second, the same UI includes the report only and the report and film simultaneous printing in parallel into a unified option page and process page, which constrains the consistent state of the same transaction number in the front and back office; third, the spatial layout of the interactive display area 12, the report outlet 30, the film outlet 40 and the card reading area 13 is layered from top to bottom and corresponding from left to right, which reduces the ergonomic conflict of card reading, code scanning and taking; fourth, the consumable observation window 31 provides an intuitive inspection port for users and maintainers, which reduces the failure caused by paper running out; fifth, the customized card reader module provides tailoring and subsequent expansion capabilities for different hospital card systems. In the embodiment, the terminal can realize the independent selection and seamless switching of multiple payment channels, the integrated arrangement and whole process prompt of report and film joint printing, the synchronous visibility of the real state of the equipment to the front-end interaction, the ergonomic optimization of card reading, code scanning and paper and film output, and the on-demand customization and compatibility of the card reader, and finally improves the success rate of report and film taking, shortens the queuing time and reduces the operation and maintenance cost.

[0031] It should be noted that the outside of the code scanning port 14 of the interactive display area 12 is integrally formed with a light interference prevention inclined cover and an anti-glare and scratch-resistant AR coating protective glass. The inclined cover and the protective glass are matched with a micro-positive pressure dust prevention and flow guide air duct arranged in the terminal host. The flow guide air duct is provided with a replaceable filter screen at the upper edge of the code scanning port 14 and forms a directional air flow with a mainboard fan. The report outlet 30 and the film outlet 40 are arranged on the vertical surface of the machine body in a structure with a relative staggered height difference and direction mark superposition. A guide baffle and a tactile recognition rib are arranged on the side of the card reading area 13 close to the film outlet 40. The guide baffle and the tactile recognition rib are synchronized with the taking animation of the printing and payment interactive screen 2. A false touch prevention capacitive protection strip is arranged at the lower edge of the machine body at the code scanning port 14. The false touch prevention capacitive protection strip is used to shield the proximity trigger in the non-code scanning process, thereby reducing the environmental light reflection and dust interference and reducing the influence of the human-machine position error on the reading and taking.

[0032] Preferably, the self-service terminal further comprises a task scheduling and state machine module in communication connection with the printing and payment interactive screen 2, the report printing module 3 and the film printing module 4. After the card swiping printing or the code scanning printing is triggered by the printing and payment interactive screen 2, corresponding printing flow charts and queue entries are established according to the report printing options or the report film simultaneous printing options of the printing options page. The flow chart defines the stages and state jump conditions of task acceptance, fee verification, queuing, drive issuance, paper ejection detection, film ejection detection and completion write-back. When hardware exceptions or user cancellations are detected at any stage, the interrupt state that can be rolled back is returned to the front end, and the queue entry is frozen until the recovery or completion rollback processing is performed.

[0033] In the embodiment, the task scheduling and state machine module is arranged and is in communication connection with the printing and payment interactive screen 2, the report printing module 3 and the film printing module 4. After the card swiping printing or the code scanning printing is triggered, the printing flow charts and the queue entries are established according to the report printing options or the report film simultaneous printing options. The flow chart defines the stages and state jump conditions of task acceptance, fee verification, queuing, drive issuance, paper ejection detection, film ejection detection and completion write-back. When hardware exceptions or user cancellations are detected at any stage, the interrupt state that can be rolled back is returned to the front end, and the queue entry is frozen until the recovery or completion rollback processing is performed. The technical problems of scattered business process, uncontrollable exception, mutual interference of jobs under concurrent conditions and inconsistency of completion state write-back can be solved. The explicit state machine is used to constrain the unique state and legal migration of each job, to avoid inconsistency such as completed fee but not landed job and completed printing but not write-back. The determination branch of freezing, recovery or rollback is provided for the exception and cancellation event to prevent repeated user submission and repeated background execution. The queue entry is used as the granularity to undertake the job scheduling under multi-machine and multi-medium printing. The scheme of the embodiment can realize the process determinacy control, exception rollback, front and back end consistent write-back and non-competitive scheduling under concurrency, and improve the overall throughput and stability.

[0034] It should be noted that the task orchestration and state machine module can assign a globally unique job number and a cost idempotent key to each queue entry, and record the state transitions of acceptance, cost verification, queuing, driver issuance, paper output detection, film output detection, and completion write-back in a persistent write-ahead log in non-volatile storage. Each stage is configured with an independent timeout threshold and an exponential backoff retry strategy, and under concurrent conditions, a combination of single-instance mutex locks and cross-station fair scheduling queues is used to control the same printer resource. When a state transition failure or abnormal process exit is detected, the task orchestration and state machine module performs precise recovery after power failure or restart based on the write-ahead log, and only allows the transition to continue from the most recently successful stable state, thereby avoiding repeated driving, cross-stage jumps, and resource contention.

[0035] Preferably, the self-service terminal is also equipped with a fee verification and rollback module. The fee verification and rollback module communicates bidirectionally with the task orchestration and state machine module and the print payment interaction screen 2. When the user completes the scan payment on the scan payment interface of the print payment interaction screen 2 or completes the card payment through the customized card reader in the card reader area 13, the fee verification and rollback module connects with the hospital's settlement system to confirm the deduction based on the order number, media type and amount. When one or both of the report printing module 3 and film printing module 4 report an anomaly, a partial failure list is generated. The rollback strategy of partial refund, whole order cancellation or reprint is triggered according to the atomicity rules of the flowchart. At the same time, the rollback progress and remaining pending items are displayed in real time on the printing process interface.

[0036] In this embodiment, a fee verification and rollback module is set up, and it communicates bidirectionally with the task orchestration and state machine module and the print payment interactive screen 2. After scanning the code on the QR code payment interface or swiping the card in the card reader area 13, the system connects to the hospital's settlement system to confirm the deduction based on the order number, media type, and amount. When the report printing module 3 or film printing module 4 reports an anomaly, a partial failure list is generated. Partial refunds, order cancellations, or reprints are triggered according to the atomicity rules of the flowchart. The rollback progress and remaining pending items are displayed in real time on the front end. This can solve the technical problems of payment and printing being disconnected, duplicate deductions, and accounting and operational disputes after partial media failures. Transactions and operations are bound by order number and media type to achieve a one-to-one mapping between financial and equipment actions. The partial failure list supports cross-media atomic processing, avoiding disputes caused by success of the report or film order. The rollback path is built into the state machine and is synchronously visible on the front end, reducing manual intervention at the window. The solution in this embodiment can achieve idempotency of deduction and refund and consistency with the operation closed loop, reduce the probability of duplicate deductions, and shorten the anomaly handling time.

[0037] It should be noted that the fee verification and rollback module can adopt a secure interface call protocol carrying a unique key and a time window stamp with the hospital end settlement system, and establish a ternary mapping of transaction records, operation records and medium sub-items for each order; when any medium printing fails, a local failure list containing the failed medium, the failure stage, the number of retryable times and the recommended reprint window is generated, and after the list is confirmed by the task scheduling and state machine module, a reprint token is automatically dispatched, the reprint token is a one-time token and is strongly bound with the original order number and the medium sub-item; if it still cannot be recovered after exceeding the set cooling time, partial refund or whole order cancellation is triggered according to the preset priority strategy, and all rollback events are written back to the hospital end in a double-channel synchronization of callback and audit log for reconciliation.

[0038] Preferably, the UI interface running on the printing and payment interactive screen 2 includes a hierarchical process prompt sub-interface, which is synchronized with the stage identification of the task scheduling and state machine module, displays different text, icons and sound prompts at four levels of acceptance, queuing, printing and taking away confirmation, and is linked with the report outlet 30 provided in the report printing function area 10 and the film outlet 40 provided in the film printing function area 11. When the paper or film is detected to be taken away and the photoelectric sensor is restored to the shielding state, the corresponding outlet area is highlighted, and the system automatically enters the completion state. Meanwhile, a bilingual and color weak visual solution switch is provided to adapt to different users.

[0039] In this embodiment, the printing and payment interactive screen 2 runs a hierarchical process prompt sub-interface, which is synchronized with the stage identification of the state machine; displays different text, icons and sound prompts at four levels of acceptance, queuing, printing and taking away confirmation; is linked with the report outlet 30 and the film outlet 40; highlights the corresponding outlet area when paper or film is detected to be taken away and the photoelectric sensor is restored to the shielding state, and enters the completion state; and provides a bilingual and color weak visual solution switch to solve the technical problems of rough information, user confusion, confusion in taking and insufficient accessibility in the front-end processing: the process is refined to a perceptible stage, and the user can predict the waiting and behavior; the sensor signal is combined to close the loop of the available and taken items on the UI and the physical outlet, reducing the wrong and missed taking; and the bilingual and color weak solution expands the accessibility of the population. The solution of this embodiment can realize process transparency, clear guidance, reliable taking confirmation and accessibility adaptation, reducing the anxiety and misoperation rate of queuing.

[0040] Preferably, the report printing module 3 is provided with a consumable monitoring sub-module, which includes a paper remaining amount sensor corresponding to the installation position of the report printer. When the paper remaining amount is detected to be lower than a threshold value, the terminal broadcasts a prompt through the broadcast port to observe the paper consumption status of the report printer through the consumable observation window 31 to confirm whether to continue printing.

[0041] In the embodiment, the report printing module 3 is provided with a consumable monitoring submodule including a paper remaining amount sensor corresponding to the assembly position of the report printer; when it is monitored that the paper remaining amount is lower than a threshold value, the user is prompted through the terminal loudspeaker to observe the paper exhaustion state through the consumable observation window 31 to confirm whether to continue printing, which can solve the technical problems of front-end unawareness when the consumable is about to be insufficient, repeated submission of the user leading to chain failure and congestion: the threshold value is formed by the sensor, and the required information for maintenance is exposed to the user and operation and maintenance with the aid of the visual window and voice prompt; in the interactive branch of confirming whether to continue, the pre-posed gate condition is provided for the state machine to avoid continuing to create a new job in the high-risk consumable state. The scheme of the embodiment can realize the three-stage consumable risk control of sensing, informing and confirming, reduce the failure and waste rate in the middle, and facilitate quick replenishment and recovery.

[0042] It should be noted that the consumable monitoring submodule can also be linked with the paper discharge roller encoder of the report printer, a joint estimation model of the remaining printable number of sheets is established according to the unit length paper discharge pulse and the historical page length statistics, and a hysteresis interval is set for the threshold value to avoid frequent jitter; low-illumination light supplement LEDs are integrated inside the consumable observation window 31, and automatically light up when it is detected that the ambient illumination is lower than a threshold value or the user turns on the maintenance mode; in the pre-printing inspection stage, the consumable monitoring submodule uploads the ratio of the estimated printable number of sheets to the number of pages of the current job to the task arrangement and state machine module as the acceptance condition, and only allows entering the limited printing or maintenance replenishment branch when the ratio is lower than the set proportion.

[0043] Preferably, the customized card reader is assembled in the card reading area 13 in a modular plug-in structure including a shielding metal bracket, a positioning limiting groove and an electrical blind plug connector, and the customized card reader establishes a USB and RS-232 composite communication channel with the interface backboard of the terminal host through the electrical blind plug connector; the drive management submodule running on the terminal host loads the corresponding certificate card protocol stack when detecting the online event of the card reader and publishes a list of available card reading interfaces to the printing and payment interaction screen 2, and the list is linked with the self-payment printing prompt on the first page, so that at least one medium among a bank magnetic stripe card, a social security card, an identity card and a hospital treatment card is selected to trigger the corresponding card swiping printing process.

[0044] In the embodiment, the customized card reader is assembled in the card reading area 13 in a modular plug-in structure, which includes a shielding metal bracket, a positioning limiting groove and an electrical blind plug connector. The card reader establishes a USB and RS-232 composite communication channel with the terminal host interface backplane through the connector. After detecting the online event of the card reader, the drive management submodule of the terminal host loads the corresponding certificate card protocol stack and publishes the list of available card reading interfaces to the front end. The list is linked with the first page of the self-payment printing prompt, so that at least one medium among the bank magnetic stripe card, the social security card, the identity card and the medical card is selected to trigger the corresponding card swiping process. This can solve the technical problems of different hospital certificate card system diversity, interface standard inconsistency, on-site reconstruction need to stop and replace the whole machine: blind plug and limiting ensure quick, safe and replacement; composite communication channel is compatible with old and new card readers; drive layer dynamically loads protocol stack according to online event, and the front end presents available media in real time to avoid misleading. The scheme of the embodiment can realize the certificate card adaptation capability of hardware modularization and software plug-and-play, shorten the online and maintenance time, and reduce the reconstruction cost and electromagnetic interference risk.

[0045] Preferably, the code scanning port 14 at the bottom of the interactive display area 12 is integrated with an infrared distance measuring sensor and a diffuse reflection anti-interference light supplement component. The infrared distance measuring sensor is in communication connection with the printing and payment interaction screen 2, and is used for real-time determination of the distance and inclination angle between the mobile terminal entering the code scanning port 14 and the window of the code scanning port 14 after the code scanning and printing are selected. When the distance is less than a first threshold value or the inclination angle deviates from the identification field of view, the printing and payment interaction screen 2 gives dynamic guidance of approaching, retreating or correcting the angle on the code scanning and payment interface, and automatically adjusts the focusing parameters and exposure parameters of the camera viewfinder according to the distance measuring result until the payment token is submitted to the fee verification and rollback module after the graphic code is effectively recognized.

[0046] In the embodiment, the code scanning port 14 at the bottom of the interactive display area 12 is integrated with an infrared distance measuring sensor and a diffuse reflection anti-interference light supplement component. The infrared distance measuring and the front end are linked, and the distance and inclination angle between the mobile terminal and the code scanning window are determined in real time after the code scanning and printing are selected. When the distance is less than a threshold value or the inclination angle deviates from the identification field, the front end gives dynamic guidance of approaching, retreating or correcting the angle, and automatically adjusts the focusing and exposure parameters of the camera viewfinder according to the distance measuring result until the payment token is submitted to the fee verification and rollback module after the graphic code is effectively recognized, which can solve the technical problems of high code scanning failure rate and long repeated attempt time caused by complex indoor light environment and variable hand posture: active distance measurement and posture determination close the relative position of people, machines and codes to a controllable range; light supplement, automatic exposure and focusing ensure the recognition in weak light, reflective or insufficient screen brightness scenes; give correction instructions before failure instead of static prompts. The scheme of the embodiment can realize the success rate and speed improvement of the code scanning path, and reduce the order interruption and queue occupation caused by code scanning timeout.
