Description

Technical Field

[0001] This invention relates to the field of physiological parameter detection technology, and in particular to a multi-information automatic acquisition and barcode printing system and method for blood pressure monitors. Background Technology

[0002] Current blood pressure monitor manufacturing inspection processes largely rely on manual operation, facing core challenges such as insufficient testing standardization, fragmented information management, broken traceability links, and overall low efficiency. Traditional manual testing methods are easily influenced by operator subjectivity, making it difficult to guarantee uniform testing conditions and objectively comparable results. Simultaneously, multi-dimensional information such as product serial numbers, test data, and environmental parameters are stored in a scattered manner, forming data silos that cannot be accurately linked to individual devices to build complete quality profiles. Manual labeling carries the risk of errors and omissions, and existing barcode information is static and limited, resulting in a lack of effective links between physical products and dynamic test data, restricting the depth and efficiency of quality traceability. The existing sequential manual processes can no longer meet the requirements of modern large-scale production for efficiency and refined quality control. Therefore, an integrated and automated systemic solution is urgently needed to achieve standardized testing, structured information, complete traceability, and efficient processes. Summary of the Invention

[0003] To address the aforementioned issues, this invention integrates several previously discrete and manual processes, such as functional performance testing of blood pressure monitors, automatic collection of multi-dimensional information, data fusion analysis, encrypted barcode generation, and precise affixing, into a seamless, automated process for automatic multi-information acquisition and barcode printing of blood pressure monitors.

[0004] The technical solution adopted in this invention is: a multi-information automatic acquisition and barcode printing system for blood pressure monitors, including a central control and data processing platform, at least one blood pressure monitor testing station, a standard blood pressure signal generation and data acquisition module, a multi-information automatic acquisition module, and an intelligent barcode printing and affixing module. The central control and data processing platform is used to receive batch task instructions, configure test and printing parameters, schedule system resources, and summarize, analyze, and associate all acquired data. Each blood pressure monitor testing station is used to fix one blood pressure monitor to be tested and integrates a station communication module for wired or wireless data communication with the blood pressure monitor to be tested. The standard blood pressure signal generation and data acquisition module is used to apply a standard pressure curve simulating human blood pressure fluctuations and a simulated pulse wave signal to the blood pressure monitor to be tested according to a preset test procedure, and simultaneously acquire the measurement result data output by the blood pressure monitor to be tested, the screen display image, and the original signal from the internal sensor. The multi-information automatic acquisition module is used to automatically acquire batch information, serial number information, environmental parameter information, and test process image information associated with the blood pressure monitor to be tested. The intelligent barcode printing and affixing module is used to generate and print encrypted two-dimensional barcodes containing comprehensive information according to the instructions of the central control and data processing platform, and automatically affix the printed barcodes to the designated positions of the corresponding blood pressure monitors.

[0005] A further improvement to the above solution is that the multi-information automatic acquisition module includes: a visual recognition unit, an environmental sensor unit, a process image acquisition unit, and a batch information input interface. The visual recognition unit is used to read the existing product serial number barcode or characters on the casing of the blood pressure monitor under test and identify its model and appearance. The environmental sensor unit is integrated near the blood pressure monitor testing station and is used to collect ambient temperature, ambient humidity, and atmospheric pressure data in real time during the testing process. The process image acquisition unit is used to capture the screen display and overall status image of the blood pressure monitor under test during key testing stages. The batch information input interface is used to receive the production batch number, operator number, and test timestamp information from the upper-level production management system or manually input.

[0006] A further improvement to the above solution is that the intelligent barcode printing and affixing module includes: a barcode generation engine, a high-speed barcode printer, a robotic arm affixing unit, and an affixing visual verification unit. The barcode generation engine receives data packets from the central control and data processing platform and generates an encrypted two-dimensional barcode image containing a test result summary, a unique traceability code, production batch information, and a data access link according to a preset format. The high-speed barcode printer prints the generated barcode image onto a label of preset specifications. The robotic arm affixing unit picks up the printed barcode label and accurately affixes it to a designated flat area on the casing of the blood pressure monitor. The affixing visual verification unit verifies the position, angle, and printing quality of the barcode by taking photos after affixing and feeds the verification results back to the central control and data processing platform.

[0007] A further improvement to the above solution is that the central control and data processing platform includes: a task and queue manager, a blood pressure monitor model and standard database, a data fusion and correlation engine, and a report and data interface unit. The task and queue manager is used to sort, schedule, and track the status of received blood pressure monitor test and printing tasks. The blood pressure monitor model and standard database stores the test pressure points, acceptable tolerance ranges, barcode affixing position coordinates, and communication protocols for different models of blood pressure monitors. The data fusion and correlation engine is used to timestamp-align, correlate, and package test data from the standard blood pressure signal generation and data acquisition module, auxiliary information from the multi-information automatic acquisition module, and internal data of the blood pressure monitor from the workstation communication module to form a complete data archive for a single blood pressure monitor. The report and data interface unit is used to generate test statistical reports and provide a standard data interface to upload the complete data archive to the enterprise quality management system or cloud server.

[0008] A further improvement to the above solution is that the standard blood pressure signal generation and data acquisition module includes: a high-precision pressure generator and controller, a simulated pulse wave generator, a multi-channel data acquisition card, and a screen image acquisition device. The high-precision pressure generator and controller is used to generate and precisely adjust the static and dynamic pressure waveforms applied to the cuff connection of the blood pressure monitor under test. The simulated pulse wave generator is used to superimpose the pressure waveform to simulate the real human pulse oscillation wave. The multi-channel data acquisition card is used to synchronously acquire the actual output pressure signal of the high-precision pressure generator and controller, the pressure feedback signal in the air circuit of the blood pressure monitor under test, and the internal digital signal of the blood pressure monitor obtained through the workstation communication module. The screen image acquisition device is used to capture the pressure and pulse values ​​displayed on the LCD screen or digital tube during the blood pressure measurement process.

[0009] A further improvement to the above scheme is that each of the blood pressure monitor testing stations also integrates: a quick-connect unit for the air circuit and a programmable power supply unit. The quick-connect unit for the air circuit is used to automatically seal and disconnect the cuff inflation port of the blood pressure monitor under test; the programmable power supply unit is used to provide working power to the blood pressure monitor under test and can simulate battery voltage drops or AC adapter power supply states.

[0010] A further improvement to the above scheme is that the information stored in the encrypted two-dimensional barcode includes at least: the blood pressure monitor's unique serial number, the deviation between the test value and the standard value of systolic / diastolic / mean pressure, the deviation between the test value and the standard value of pulse rate, the temperature and humidity of the test environment, the test pass status indicator, the test completion timestamp, and an encrypted URL link pointing to the complete data archive in the cloud.

[0011] A further improvement to the above solution is that the complete data archive of a single blood pressure monitor generated by the data fusion and correlation engine is a structured data file, which includes: original test pressure curve data, blood pressure monitor response curve data, all acquired image files, environmental sensor logs, communication interaction logs, and the final quality judgment conclusion.

[0012] An automatic acquisition and barcode printing method based on a multi-information automatic acquisition and barcode printing system for blood pressure monitors includes the following steps: Step S100: Load the blood pressure monitor to be tested into the blood pressure monitor testing station and fix it. The system automatically reads its shell serial number through the visual recognition unit and establishes a connection through the station communication module. In step S200, the central control and data processing platform retrieves the corresponding test pressure curve, pass standard, and barcode affixing coordinates from the database based on the identified model; the multi-information automatic acquisition module begins recording environmental parameters and batch information. In step S300, the quick-connect unit of the air circuit at the workstation automatically connects to the air inlet of the blood pressure monitor, and the standard blood pressure signal generation and data acquisition module applies standard signals containing different static pressure points and dynamic blood pressure waveforms in sequence according to the test procedure. In step S400, the pressure and pulse values ​​displayed by the blood pressure monitor, the screen image, the internal sensor signals, and the actual output signal of the standard module are acquired simultaneously; the process image acquisition unit of the multi-information automatic acquisition module takes pictures at key test points. In step S500, the central control and data processing platform analyzes the collected data in real time, calculates the measurement error, and determines whether the test passes or fails based on the qualification standards; the data fusion and correlation engine associates and packages all test data, images, environmental information, and batch serial numbers. In step S600, the barcode generation engine of the intelligent barcode printing and affixing module receives the data packet, generates an encrypted two-dimensional barcode containing key test results and traceability links, and prints it by a high-speed barcode printer. In step S700, the robotic arm attaching unit grabs the barcode label and accurately attaches it to the designated position on the blood pressure monitor casing; the attaching vision verification unit verifies the attaching result. In step S800, after the process of a single blood pressure monitor is completed, the rapid gas connection unit disconnects to prepare for the next cycle; the central control and data processing platform summarizes the batch reports and uploads all complete data files to the designated server.

[0013] A further improvement to the above scheme is that, in step S300, the test procedure includes static pressure accuracy test, dynamic blood pressure tracking test, and heart rate detection accuracy test, which are accomplished by applying multiple static pressure points from low pressure to high pressure and simulating dynamic blood pressure waveforms with different patterns of rapid rise and slow fall.

[0014] A further improvement to the above scheme is that, in step S500, when the data fusion and association engine performs association packaging, all data files (including pressure data files, image files, and log files) generated by the same blood pressure monitor are assigned a unique data packet ID that is bound to the blood pressure monitor serial number, and this ID is encoded into the encrypted two-dimensional barcode generated in step S600.

[0015] A further improvement to the above scheme is that, in step S700, if the attaching visual verification unit detects that the barcode attaching position deviation exceeds the tolerance, or that the barcode image is blurry or missing, the central control and data processing platform will trigger an alarm and control the robotic arm attaching unit to re-execute the attaching operation or remove the workstation from the maintenance queue.

[0016] The beneficial effects of this invention are: Compared to existing blood pressure monitor barcode printing, this invention integrates several previously discrete, manual processes—including functional performance testing, automatic collection of multi-dimensional information (serial number, environment, images), data fusion analysis, encrypted barcode generation, and precise labeling—into a seamless, automated workflow. This eliminates manual handling, recording, comparison, and labeling between different processes, avoiding problems such as mislabeling, omissions, and recording errors caused by human fatigue or negligence. The central control and data processing platform achieves closed-loop management of the entire process from task assignment to final data archiving, reducing the testing and labeling time for a single blood pressure monitor from several minutes to tens of seconds, significantly improving the overall throughput of the production line, and is particularly suitable for large-scale factory inspection. Traditionally, test data, environmental records, product serial numbers, and appearance images are often scattered across different paper records or independent systems, making effective correlation and long-term traceability difficult. This invention, through a "multi-information automatic acquisition module" and a "data fusion and correlation engine," automatically captures and timestamps all relevant information, generating a unique, structured, and complete data archive for each blood pressure monitor. Finally, an encrypted two-dimensional barcode containing a key summary and a unique traceability code is permanently affixed to the product. Quality inspectors or end users can quickly verify the product's authenticity, query key test results, or access the complete cloud archive via an encrypted link by scanning the barcode. This achieves full lifecycle quality traceability from production to use, greatly enhancing quality control capabilities and consumer confidence. The "standard blood pressure signal generation and data acquisition module" provides high-precision, repeatable simulated blood pressure and pulse wave signals, replacing the random errors that may arise from traditional manual pressure sources. It simultaneously collects the blood pressure monitor's displayed value, internal signals, and the actual applied standard signal, and automatically compares and judges them through a data analysis engine, completely eliminating interference from subjective human judgment. This ensures that every blood pressure monitor is tested under completely consistent standard conditions, revolutionizing the reliability and comparability of test results. The visual recognition unit automatically identifies the product model, and the central platform can automatically call up the corresponding test procedures and labeling coordinates, achieving flexible operation of "place and test immediately, test and label immediately." The intelligent barcode printing and labeling module features post-labeling visual verification, automatically judging label quality and triggering relabeling or alarms to ensure 100% reliability of the final output. The generated encrypted 2D barcode integrates anti-counterfeiting verification mechanisms and data access. This effectively combats product counterfeiting and connects physical products with massive amounts of quality data in the digital world. Through systematic innovation, this invention not only achieves a leap in automation and intelligence in the blood pressure monitor testing and labeling process but also constructs a data-centric, traceable, and highly reliable quality management system. This system has significant industrial application value for improving the overall quality level, production efficiency, and brand value of blood pressure monitor products.

[0017] Based on an automated information acquisition and barcode printing system for blood pressure monitors, this method integrates multiple stages—including blood pressure monitor identification, testing, data acquisition, analysis and judgment, labeling, and archiving—into a highly coordinated and precisely timed automated process, fully leveraging the system's hardware capabilities. Traditionally discrete steps reliant on manual intervention, such as loading identification, airway connection, test execution, data recording, result judgment, label printing, and affixing, are integrated into a single automated production line (steps S100 to S800). Seamless integration of each step, centrally scheduled by a platform, eliminates waiting times, manual handling, and operational delays between processes, significantly reducing the processing time for a single blood pressure monitor. Supporting multi-station parallel and asynchronous operation, the overall system throughput is increased several times over, perfectly adapting to the pace requirements of modern high-speed production lines. Full-process automation eliminates the randomness of human intervention, ensuring that every product undergoes a completely consistent and standardized processing procedure, fundamentally guaranteeing consistent output quality. Through a data fusion and correlation engine, all information, including the original curves and results of functional testing (S400), product unique identification information (S100), production batch and environmental context (S200, S400), process visualization evidence (S400), and final quality judgment (S500), is timestamped and structured and packaged with a unique serial number as the core. The resulting "complete data archive" is strongly bound to the entity encrypted barcodes produced in steps S600-S700. This achieves a precise mapping from a single physical product to its full-dimensional digital twin archive, providing a highly granular and indisputable data foundation for production quality analysis, after-sales problem tracing, and process improvement, elevating quality management from result sampling to a new level of full-process digital monitoring.

The visual recognition unit automatically identifies the product model, and the central platform can automatically call up the corresponding test procedures and labeling coordinates, achieving flexible operation of "place and test immediately, test and label immediately." The intelligent barcode printing and labeling module 5 features post-labeling visual verification, automatically judging label quality and triggering relabeling or alarms to ensure 100% reliability of the final output. The generated encrypted 2D barcode integrates anti-counterfeiting verification mechanisms and data access. This effectively combats product counterfeiting and connects physical products with massive amounts of quality data in the digital world. Through systematic innovation, this embodiment not only achieves a leap in automation and intelligence in the blood pressure monitor testing and labeling process but also constructs a data-centric, traceable, and highly reliable quality management system. This system has significant industrial application value for improving the overall quality level, production efficiency, and brand value of blood pressure monitor products.

[0025] See Figure 5As shown, the multi-information automatic acquisition module 4 includes: a visual recognition unit 41, an environmental sensor unit 42, a process image acquisition unit 43, and a batch information input interface 44. The visual recognition unit 41 is used to read the product serial number barcode or characters already on the casing of the blood pressure monitor 21 under test, and identify its model and appearance. The environmental sensor unit 42 is integrated near the blood pressure monitor testing station 2 and is used to collect environmental temperature, environmental humidity, and atmospheric pressure data in real time during the testing process.

This embodiment constructs a comprehensive automatic information acquisition network through modular design. The visual recognition unit 41 automatically acquires product identity information, eliminating errors from manual transcription.

The batch information interface achieves seamless integration of production management and quality data. The units work together to generate a digital profile for each blood pressure monitor that includes complete contextual information.

[0026] See Figure 6 As shown, the intelligent barcode printing and affixing module 5 includes: a barcode generation engine 51, a high-speed barcode printer 52, a robotic arm affixing unit 53, and an affixing visual verification unit 54. The barcode generation engine 51 receives data packets from the central control and data processing platform 1 and generates an encrypted two-dimensional barcode image containing a test result summary, a unique traceability code, production batch information, and a data access link according to a preset format. The high-speed barcode printer 52 prints the generated barcode image onto a label of preset specifications. The robotic arm affixing unit 53 picks up the printed barcode label and accurately affixes it to a designated flat area on the casing of the blood pressure monitor 21. The affixing visual verification unit 54 verifies the position, angle, and printing quality of the barcode by taking a photograph after affixing and feeds the verification result back to the central control and data processing platform 1. This embodiment achieves precise closed-loop control from data to physical label. The barcode generation engine 51 converts test data into encrypted barcode information in real time. The robotic arm affixing unit 53 ensures high consistency and accuracy of the labeling position. After completion, the visual inspection unit 54 automatically detects the labeling quality and triggers re-labeling or an alarm for any non-conforming labels. The entire process ensures that the traceability labels on each product are correct, clear, and effective, achieving zero-defect output in the labeling process.

[0027] See Figure 2As shown, the central control and data processing platform 1 includes: a task and queue manager 11, a blood pressure monitor model and standard database 12, a data fusion and association engine 13, and a report and data interface unit 14. The task and queue manager 11 is used to sort, schedule, and track the status of received blood pressure monitor test and printing tasks. The blood pressure monitor model and standard database 12 stores the test pressure points, acceptable tolerance ranges, barcode affixing position coordinates, and communication protocols for different models of blood pressure monitors. The data fusion and association engine 13 is used to timestamp-align, associate, and package the test data from the standard blood pressure signal generation and data acquisition module 3, the auxiliary information from the multi-information automatic acquisition module 4, and the internal data of the blood pressure monitor from the workstation communication module 22 to form a complete data archive for a single blood pressure monitor. The report and data interface unit 14 is used to generate test statistical reports and provide a standard data interface to upload the complete data archive to the enterprise quality management system or cloud server. This embodiment constructs the intelligent scheduling and data processing core of the system. The task manager optimizes the test process and improves overall efficiency.

[0028] See Figure 4 As shown, the standard blood pressure signal generation and data acquisition module 3 includes: a high-precision pressure generator and controller 31, a simulated pulse wave generator 32, a multi-channel data acquisition card 33, and a screen image acquisition device 34. The high-precision pressure generator and controller 31 is used to generate and precisely adjust the static and dynamic pressure waveforms applied to the cuff connection of the blood pressure monitor 21 under test. The simulated pulse wave generator 32 is used to superimpose the pressure waveform to simulate the real human pulse oscillation wave. The multi-channel data acquisition card 33 is used to synchronously acquire the actual output pressure signal of the high-precision pressure generator and controller 31, the pressure feedback signal in the air path of the blood pressure monitor 21 under test, and the internal digital signal of the blood pressure monitor obtained through the workstation communication module 22. The screen image acquisition device 34 is used to capture the pressure and pulse values ​​displayed on the LCD screen or digital tube during the blood pressure monitor measurement process. This embodiment provides a high-fidelity, traceable test benchmark. The high-precision pressure controller generates accurate static and dynamic pressure waveforms. The simulated pulse wave generator 32 superimposes physiological characteristic signals to simulate a real measurement scenario. A multi-channel acquisition card synchronously records standard signals and device responses, enabling precise error analysis. A screen image acquisition unit 34 verifies the final display results. This module ensures the ability to comprehensively and objectively evaluate the performance of the blood pressure monitor.

[0029] See Figure 3As shown, each of the blood pressure monitor test stations 2 also integrates: a quick-connect gas path unit 23 and a programmable power supply unit 24. The quick-connect gas path unit 23 is used for automatic sealing connection and disconnection with the cuff inflation port of the blood pressure monitor 21 under test; the programmable power supply unit 24 is used to provide operating power to the blood pressure monitor 21 under test and can simulate battery voltage drops or AC adapter power supply states. This embodiment realizes the automation of the test interface and the simulation test of power conditions. The quick-connect gas path unit 23 automatically completes the sealing connection, ensuring accurate and reliable pressure transmission and improving test efficiency. The programmable power supply unit 24 simulates real power supply states such as battery voltage drops, verifying the working stability of the equipment under different power conditions. The two units expand the test coverage and provide a solid foundation for automated testing.

[0030] The encrypted 2D barcode stores at least the following information: the blood pressure monitor's unique serial number, the deviation of the tested systolic / diastolic / mean blood pressure values ​​from the standard values, the deviation of the tested pulse rate values ​​from the standard values, the temperature and humidity of the testing environment, a test pass status indicator, a test completion timestamp, and an encrypted URL link to a complete data archive in the cloud. This embodiment designs an intelligent identification scheme that balances on-site verification and in-depth traceability. The barcode contains summary information such as key test results and environmental data to meet the needs of rapid verification. The encrypted URL link points to a complete data archive in the cloud, realizing the association between the physical identifier and the digital archive. While ensuring information security, it greatly expands the information capacity and traceability depth of a single barcode.

[0031] The complete data archive for a single blood pressure monitor generated by the data fusion and correlation engine 13 is a structured data file. Its content includes: raw test pressure curve data, blood pressure monitor response curve data, all acquired image files, environmental sensor logs, communication interaction logs, and the final quality assessment conclusion. This embodiment defines a standardized quality data asset format. The archive contains comprehensive information such as raw test curves, process images, and environmental logs, organized in a structured manner. This unified format facilitates automated computer processing and analysis, providing a high-quality data foundation for quality big data applications and enhancing the reuse value and management efficiency of quality data.

[0032] See Figures 1-7 As shown, an automatic acquisition and barcode printing method based on a multi-information automatic acquisition and barcode printing system for blood pressure monitors includes the following steps: Step S100: The blood pressure monitor 21 to be tested is loaded onto the blood pressure monitor testing station 2 and fixed. The system automatically reads its shell serial number through the visual recognition unit 41 and establishes a connection through the station communication module 22. In step S200, the central control and data processing platform 1 retrieves the corresponding test pressure curve, qualification standard, and barcode affixing coordinates from the database based on the identified model; the multi-information automatic acquisition module 4 begins recording environmental parameters and batch information. In step S300, the quick-connect unit 23 of the workstation automatically connects to the inflation port of the blood pressure monitor, and the standard blood pressure signal generation and data acquisition module 3 applies standard signals containing different static pressure points and dynamic blood pressure waveforms in sequence according to the test procedure. In step S400, the pressure and pulse values ​​displayed by the blood pressure monitor, the screen image, the internal sensor signals, and the actual output signals of the standard module are acquired simultaneously; the process image acquisition unit 43 of the multi-information automatic acquisition module 4 takes pictures at key test points. In step S500, the central control and data processing platform 1 analyzes the collected data in real time, calculates the measurement error, and determines whether the test passes or fails based on the qualification standard; the data fusion and association engine 13 associates and packages all test data, images, environmental information and batch serial numbers. In step S600, the barcode generation engine 51 of the intelligent barcode printing and attaching module 5 receives the data packet, generates an encrypted two-dimensional barcode containing key test results and traceability links, and prints it by the high-speed barcode printer 52. In step S700, the robotic arm attaching unit 53 picks up the barcode label and accurately attaches it to the designated position on the blood pressure monitor casing; the attaching visual verification unit 54 verifies the attaching result. In step S800, after the process of a single blood pressure monitor is completed, the rapid gas connection unit 23 is disconnected to prepare for the next cycle; the central control and data processing platform 1 summarizes the batch reports and uploads all complete data files to the designated server.

[0033] This embodiment fully leverages the system's hardware capabilities by orchestrating multiple stages—including blood pressure monitor identification, testing, data acquisition, analysis and judgment, labeling, and archiving—into a highly coordinated and precisely timed automated process. Traditionally discrete steps reliant on manual intervention, such as loading and identification, gas path connection, test execution, data recording, result judgment, label printing, and affixing, are integrated into a single automated production line (steps S100 to S800). Each step in the process is seamlessly connected and centrally scheduled, eliminating waiting times, manual handling, and operational delays between processes, significantly reducing the processing time for a single blood pressure monitor. Supporting multi-station parallel and asynchronous operations, the overall system throughput is increased several times over, perfectly adapting to the pace requirements of modern high-speed production lines. Full-process automation eliminates the randomness of human operation, ensuring that every product undergoes a completely consistent and standardized processing procedure, fundamentally guaranteeing consistent output quality. Through the data fusion and correlation engine 13, all information, including the original curves and results of functional testing (S400), product unique identification information (S100), production batch and environmental context (S200, S400), process visualization evidence (S400), and final quality judgment (S500), is timestamped and structured and packaged with a unique serial number as the core. The resulting "complete data archive" is strongly bound to the entity encrypted barcodes produced in steps S600-S700. This achieves a precise mapping from a single physical product to its full-dimensional digital twin archive, providing a highly granular and indisputable data foundation for production quality analysis, after-sales problem tracing, and process improvement, elevating quality management from result sampling to a new level of full-process digital monitoring.

[0034] In step S300, the test procedure includes static pressure accuracy testing, dynamic blood pressure tracking testing, and heart rate detection accuracy testing. This is accomplished by applying multiple static pressure points from low to high pressure and simulating dynamic blood pressure waveforms with different patterns of rapid rise and slow fall. This embodiment establishes a systematic performance evaluation system. Through the combination of static accuracy, dynamic tracking, and heart rate accuracy tests, the core performance of the blood pressure monitor under different physiological states is comprehensively assessed. This procedure not only verifies basic functions but also evaluates the reliability of the device in dynamic scenarios, significantly improving the clinical applicability of the product.

[0035] In step S500, when the data fusion and association engine 13 performs association and packaging, it assigns a unique data packet ID (bound to the blood pressure monitor's serial number) to all data files (including pressure data files, image files, and log files) generated by the same blood pressure monitor, and encodes this ID into the encrypted two-dimensional barcode generated in step S600. This embodiment constructs an efficient and accurate data traceability chain. By assigning a unique ID to all data files of each device and encoding them into a barcode, it achieves "one-click" traceability from the physical product to its digital archive. This mechanism simplifies data retrieval logic, improves traceability efficiency, and is a key technological link connecting the physical and digital worlds.

[0036] In step S700, if the labeling visual verification unit 54 detects that the barcode labeling position deviation exceeds the tolerance, or that the barcode image is blurry or missing, the central control and data processing platform 1 will trigger an alarm and control the robotic arm labeling unit 53 to re-execute the labeling operation or remove the workstation from the maintenance queue. This embodiment realizes intelligent quality management of the labeling process. Through a closed-loop process of automatic detection, feedback alarm, and error correction and relabeling, it ensures that each barcode is correctly positioned and clearly readable. This mechanism guarantees the effectiveness of traceability identification, improves production first-pass yield, and reduces subsequent problems caused by poor labeling.

[0037] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
