Furthermore, there was a limitation in that it was difficult to integrate reference data acquired from external equipment, such as data analysis devices or load testers, with the measurements of the inspection device, making it difficult to flexibly apply inspection standards across various products, models, and test conditions.

[0026] Hereinafter, with reference to FIGS. 1 to 3, a user interface device for testing a lower limb prosthesis according to an embodiment of the present invention and a method for testing a lower limb prosthesis using the same will be described as follows.

[0027] A user interface device (10) for lower limb prosthesis testing according to one embodiment of the present invention is a user interface device for lower limb prosthesis testing that communicates with an electronically controlled lower limb prosthesis component integration testing device, and comprises: a testing item selection screen configuration unit (11) that provides a plurality of testing items for the components of the lower limb prosthesis in the form of a list or buttons, switches to a testing screen corresponding to the selected testing item, and arranges testing start and stop controls, data requests, status display areas, and basic parameter input areas required for the corresponding testing within each testing screen; and a communication processing unit (12) that transmits and receives control signals and sensor data including mode execution commands, parameter transmission, data requests, and response processing with the integration testing device (1) according to a communication protocol, converts the received sensor values, status information, and judgment results into a format suitable for screen display and displays them in real time, and also displays the communication status and whether an error has occurred. The system may be configured to include: an external equipment linkage inspection condition setting unit (13) that inputs and stores inspection conditions including inspection standard values, tolerances, test sections, and speeds, and manually inputs standard data or test results obtained from external equipment including data analysis equipment or load testers, or loads them from a file, and uses them for judgment together with the measurement values ​​of the integrated inspection device; and an inspection data visualization log management unit (14) that displays sensor data collected during the inspection process and judgment results in real-time in the form of graphs and tables, and stores and retrieves inspection logs including product identification information, inspection items, inspection dates and times, applicable standards, and judgment results in a file or database format.

[0028] Referring to FIG. 1, a user interface device (10) for inspecting a lower limb prosthesis according to one embodiment of the present invention (hereinafter referred to as the "user interface device") may be configured to communicate with an electronically controlled lower limb prosthesis component integrated inspection device (1) (hereinafter referred to as the "integrated inspection device") to consistently process, in a single screen system, the selection of inspection items for each component of the lower limb prosthesis, real-time display of sensor data, setting of inspection conditions linked to external equipment, visualization of inspection data, and storage and management of inspection logs. Here, "electronically controlled lower limb prosthesis" refers to an electronically controlled lower limb assistive device including multiple sensors and a hydraulic drive unit, and "integrated inspection device (1)" may refer to a device that integrally performs measurement and control functions for each component of the lower limb prosthesis. The user interface device (10) may be configured to include an inspection item selection screen configuration unit (11), a communication processing unit (12), an external equipment linked inspection condition setting unit (13), and an inspection data visualization log management unit (14).

[0029] The inspection item selection screen configuration unit (11) can provide the user with a plurality of inspection items for the components of the lower limb prosthesis in the form of a list or buttons, and perform the function of switching to an inspection screen corresponding to the inspection item selected by the user. Here, "inspection item" refers to an individual inspection item performed on each component of the lower limb prosthesis, such as a sensor inspection, hydraulic inspection, drive unit inspection, and communication status inspection, and can be arranged in the form of a list or buttons on the left panel of the screen as shown in FIG. 2. The inspection item selection screen configuration unit (11) can be configured to arrange test start and stop control buttons, data request buttons, a status display area, and a basic parameter input area required for the inspection within each inspection screen. Here, "basic parameter" refers to an input value that must be set in advance to perform the inspection, such as an inspection standard value, tolerance, test section, and speed, and can be provided in the form of an input field within the inspection screen as shown in the upper area of ​​FIG. 2. In this way, through the inspection item selection screen configuration unit (11), the operator can immediately receive a screen configuration and control interface optimized for the inspection simply by selecting the desired item among the plurality of inspection items.

[0030] The communication processing unit (12) may be configured to transmit and receive control signals and sensor data, including mode execution commands, parameter transmission, and data request and response processing, to the integrated inspection device (1) according to a communication protocol. Here, "communication protocol" refers to a communication standard pre-defined by both parties to exchange control signals and data between the user interface device (10) and the integrated inspection device (1), and, for example, wired serial communication, USB communication, or Ethernet-based communication protocols may be applied. The communication processing unit (12) may be configured to convert sensor values, status information, and judgment results received from the integrated inspection device (1) into a format suitable for screen display and display them in real time. Additionally, the communication processing unit (12) may be configured to display the current communication connection status and whether an error has occurred on the screen together, such as the communication status panel shown at the bottom right of FIG. 2, so that the operator can immediately recognize and respond to any communication abnormalities during the inspection.

[0031] The external equipment linkage inspection condition setting unit (13) may be configured to input and store inspection conditions including inspection standard values, allowable error, test section, and speed, and to manually input standard data or test results obtained from external equipment including data analysis equipment or load testing equipment, or to load them from a file and use them together with the measurement values ​​of the integrated inspection device (1) for judgment. Here, "external equipment" refers to measurement and testing equipment such as data analysis equipment or load testing equipment that is operated separately from the user interface device (10) and the integrated inspection device (1), and the standard data or test results obtained from said equipment may be input into the external equipment linkage inspection condition setting unit (13) as shown in FIG. 1. In addition, "standard data" refers to a value that serves as a standard for the pass / fail judgment of an inspection, and refers to data that is separately measured and analyzed by external equipment; by utilizing this together with the measurement values ​​of the integrated inspection device (1), it becomes possible to flexibly apply various inspection standards that are difficult to implement with a single inspection device alone. The input and storage of inspection conditions can be performed through the parameter input area, and reference data from external equipment can be provided by automatically loading it via a file load function or by the operator directly entering it manually.

[0032] The inspection data visualization log management unit (14) can be configured to display sensor data collected during the inspection process and judgment results in real-time in the form of graphs and tables, and to store and retrieve inspection logs including product identification information, inspection items, inspection date and time, application criteria, and judgment results in a file or database format. Here, "product identification information" refers to information such as a product code, model name, and serial number that can uniquely identify the lower limb prosthesis subject to inspection, and "inspection log" refers to record information such as inspection items, inspection date and time, application criteria, and judgment results generated when performing individual inspections. As illustrated in FIG. 2, the collected sensor data can be displayed in real-time in the form of a graph based on a time axis, and the measurement values ​​and judgment results for each inspection item can be displayed together in a table format. The inspection logs can be stored in a file format or a database format, and the stored inspection logs can be retrieved and viewed as needed, enabling systematic management of inspection history throughout the lower limb prosthesis assembly and manufacturing process and after-sales service process.

[0033] In addition, according to one embodiment of the present invention, the external equipment linkage inspection condition setting unit (13) may be configured to correspond the reference data loaded from the external equipment with the measurement value received from the integrated inspection device (1) and apply it as a pass / fail judgment standard for each inspection condition.

[0034] Referring to FIG. 1, in a user interface device (10) according to one embodiment of the present invention, the external equipment linkage inspection condition setting unit (13) may be configured to correspond standard data loaded from external equipment with measurement values ​​received from an integrated inspection device (1) and apply them as pass / fail judgment criteria for each inspection condition.

[0035] Specifically, as described above, the external equipment linkage inspection condition setting unit (13) can acquire reference data from external equipment, such as data analysis equipment or a load tester, by means of file loading or manual input. The external equipment linkage inspection condition setting unit (13) performs a process of matching the acquired reference data with the measurement value received from the integrated inspection device (1). Here, "matching" may mean a process of mapping the items of the reference data acquired from the external equipment with the items of the measurement value received from the integrated inspection device (1) according to inspection conditions, thereby connecting the reference value and the measurement value for the same inspection item so that they can be compared and utilized. For example, the load test reference value acquired from the external equipment and the hydraulic sensor measurement value received from the integrated inspection device (1) can be matched to the same inspection item, and utilized in a way that determines whether the measurement value is within the allowable error range of the reference value.

[0036] The corresponding reference data and measurement values ​​can be applied as pass / fail judgment criteria for each inspection condition. Here, "pass / fail judgment criteria" refers to a standard in which a measurement value is judged as pass if it is within the allowable range and fail if it is outside the allowable range, based on the reference value and allowable error range set for each inspection item. As shown in the judgment result table of FIG. 2, the pass or fail judgment result for each inspection item's measurement value can be displayed on the screen. Through this configuration, the user interface device (10) can easily switch and apply inspection criteria simply by loading the reference data of an external device that matches the conditions, even when the product, model, or test conditions change, thereby enabling flexible response to various lower limb prosthetic product specifications.

[0037] In addition, according to one embodiment of the present invention, the inspection data visualization log management unit (14) is configured to classify and retrieve stored inspection logs by product identification information, and can be configured to be used for quality tracking and defect cause analysis during the lower limb assembly and manufacturing process and after-sales service process.

[0038] Referring to FIGS. 1 and 2, in a user interface device (10) according to one embodiment of the present invention, the inspection data visualization log management unit (14) is configured to classify and retrieve stored inspection logs by product identification information, and can be configured to be utilized for quality tracking and defect cause analysis during the lower limb assembly and manufacturing process and after-sales service process.

[0039] Specifically, as described above, the inspection data visualization log management unit (14) can store an inspection log containing product identification information, inspection items, inspection date and time, applicable criteria, and judgment results in a file or database format whenever an inspection is performed. The inspection data visualization log management unit (14) can classify and manage the inspection logs stored in this manner by product identification information, where "classification by product identification information" means grouping inspection logs with the same product code, model name, or serial number into a single history group for management. Through this, multiple inspection histories for a specific lower limb prosthesis product can be systematically managed as a single product unit, and the operator can quickly retrieve the desired inspection history based on the product identification information.

[0040] In addition, the inspection data visualization log management unit (14) can visualize and display the retrieved inspection logs in the form of graphs and tables as shown in FIG. 2, so that the operator can grasp at a glance the trends in measured values ​​by inspection item of a specific product, changes in judgment results, and the history of changes in application standards. Such visualization and classification / inquiry functions of inspection history can be utilized as a quality tracking means to systematically track whether quality standards are met in the assembly and manufacturing process of lower limb prostheses. Here, "quality tracking" may mean tracking the inspection results at each assembly and manufacturing stage of a specific product in a time series to verify whether quality standards are continuously met.

[0041] In addition, if a defect occurs in a specific lower limb prosthesis product during the after-sales service process, the past inspection logs of the product can be viewed by product identification information through the inspection data visualization log management unit (14), thereby allowing for the identification of the inspection item where the defect occurred, signs of abnormality in the measurement value, and the time of change in the judgment result, enabling rapid analysis of the cause of the defect. Here, "defect cause analysis" may refer to the process of identifying the root cause of the defect by retrospectively analyzing the trend of measurement values ​​and judgment results prior to the time of the defect occurrence based on the stored inspection logs. Through such a configuration, the user interface device (10) can contribute to increasing the reliability and efficiency of quality control throughout the assembly and manufacturing process and after-sales service process of the lower limb prosthesis.

[0042] Meanwhile, a lower limb prosthesis examination method using a user interface device (10) for lower limb prosthesis examination according to one embodiment of the present invention is a lower limb prosthesis examination method performed by a user interface device (10) communicating with an electronically controlled lower limb prosthesis component integrated examination device (1), wherein the user interface device (10) provides a plurality of examination items for lower limb prosthesis components in the form of a list or buttons, switches to an examination screen corresponding to an examination item selected by the user, and arranges a test start and stop control, a data request, a status display area, and a basic parameter input area within the examination screen; and the user interface device (10) transmits and receives control signals and sensor data including mode execution commands, parameter transmission, data request and response processing with the integrated examination device according to a communication protocol, displays the received sensor value, status information and judgment result on the screen in real time, and displays the communication status and whether an error has occurred together. The user interface device (10) may be configured to include the step of inputting and storing inspection conditions including inspection standard values, tolerances, test sections, and speeds, and manually inputting standard data or test results obtained from external equipment or loading them from a file to use for judgment together with the measurement values ​​of the integrated inspection device (1); the step of the user interface device (10) visualizing the collected sensor data and judgment results in real-time in the form of graphs and tables; and the step of the user interface device (10) storing an inspection log including product identification information, inspection items, inspection dates and times, applicable standards, and judgment results in a file or database format.

[0043] Referring to FIG. 3, a lower limb prosthesis examination method according to one embodiment of the present invention is composed of a series of steps performed by the aforementioned user interface device (10), and each step can be performed sequentially.

[0044] First, the user interface device (10) can perform the step of providing a plurality of inspection items for lower limb prosthetic components to the user in the form of a list or buttons, switching to an inspection screen corresponding to the inspection item selected by the user, and arranging a test start and stop control button, a data request button, a status display area, and a basic parameter input area within the inspection screen. As described above, the user can immediately receive a screen configuration and control interface optimized for the inspection simply by selecting a desired item among the inspection items displayed on the left panel of FIG. 2, and can pre-set inspection conditions such as inspection standard values, tolerances, test sections, and speed through the basic parameter input area within the inspection screen.

[0045] Next, the user interface device (10) can perform the step of transmitting and receiving control signals and sensor data, including mode execution commands, parameter transmission, data request and response processing, with the integrated inspection device (1) according to a communication protocol, displaying the received sensor values, status information, and judgment results on the screen in real time, and displaying the communication status and whether an error has occurred together. The user interface device (10) can initiate an inspection by transmitting the parameters set in step S1 to the integrated inspection device (1) and transmitting a mode execution command, and the sensor values, status information, and judgment results received from the integrated inspection device (1) can be displayed in real time in the central graph area and judgment result table of FIG. 2. In addition, as described above, since the communication connection status and whether an error has occurred are displayed together on the screen through the communication status panel, the operator can immediately recognize and respond to any communication abnormalities during the inspection.

[0046] Next, the user interface device (10) can input and store inspection conditions including inspection standard values, tolerances, test sections, and speeds, and perform the step of manually inputting standard data or test results obtained from external equipment or loading them from a file to use in judgment together with the measurement values ​​of the integrated inspection device (1). As described above, the standard data loaded from external equipment corresponds to the measurement values ​​received from the integrated inspection device (1) according to inspection conditions and can be applied as a pass / fail judgment standard, thereby enabling flexible switching and application of inspection standards according to various products, models, and test conditions.

[0047] Next, the user interface device (10) can perform the step of visualizing the collected sensor data and judgment results in the form of a graph and a table in real time. As shown in FIG. 2, the sensor data can be displayed in real time in the form of a graph based on a time axis, and a reference line indicating a reference value is also displayed so that the operator can intuitively check the deviation between the measured value and the reference value. In addition, the measured value and judgment result for each inspection item can be displayed together in the form of a table, making it possible to grasp the results for multiple inspection items at a glance.

[0048] Finally, the user interface device (10) may perform the step of storing an inspection log, including product identification information, inspection items, inspection date and time, applicable criteria, and judgment results, in a file or database format. As described above, the stored inspection log can be classified and retrieved by product identification information and can be utilized for quality tracking and defect cause analysis during the assembly and manufacturing process of the lower limb prosthesis and the after-sales service process. Through the aforementioned series of processes, the user interface device (10) can consistently perform the entire inspection procedure, from selecting inspection items for the components of the lower limb prosthesis to storing the inspection log, in a standardized manner, thereby reducing variations in the inspection procedure depending on the operator and increasing the efficiency and reliability of the inspection work.

[0049] The usage state according to one embodiment of the user interface device for lower limb prosthesis testing and the lower limb prosthesis testing method (hydraulic) using the same, as described above, is as follows.

[0050] The operator first connects the user interface device (10) and the integrated inspection device (1) according to a communication protocol, and then operates the user interface device (10). When the user interface device (10) is operated, the inspection item selection screen configuration unit (11) displays a plurality of inspection items for lower limb prosthetic components, such as sensor inspection, hydraulic inspection, drive unit inspection, communication status inspection, and after-sales service inspection, on the screen in the form of a list or buttons, as shown in the left panel of FIG. 2. When the operator selects the hydraulic inspection as an inspection item corresponding to the inspection target among these, the inspection item selection screen configuration unit (11) switches to an inspection screen corresponding to the hydraulic inspection and automatically places a test start and stop control button, a data request button, a status display area, and a basic parameter input area required for the hydraulic inspection within the inspection screen.

[0051] After switching to the inspection screen, the operator sets the inspection conditions through the external equipment linkage inspection condition setting unit (13) prior to the inspection. The operator can directly input inspection conditions such as inspection standard values, tolerances, test sections, and speeds into the parameter input area, or load a standard data file previously acquired from external equipment, such as a load tester, through a file load function. The external equipment linkage inspection condition setting unit (13) corresponds the loaded standard data with the measurement values ​​received from the integrated inspection device (1) and each inspection condition to set the pass / fail judgment standard, and saves the set inspection conditions. For example, a hydraulic pressure standard value of 1500N and a tolerance of ±5% acquired from a load tester can be set as the pass / fail judgment standard.

[0052] When the inspection conditions are set, the operator starts the inspection by operating the test start button on the inspection screen. When the test start command is entered, the communication processing unit (12) transmits a mode execution command and set parameters to the integrated inspection device (1) according to the communication protocol, and receives a response signal including hydraulic sensor data, status information, and judgment results from the integrated inspection device (1). The communication processing unit (12) converts the received data into a format suitable for screen display and transmits it in real time, and since the current communication connection status and whether an error has occurred are displayed together on the communication status panel of FIG. 2, the operator can immediately check for communication abnormalities during the inspection.

[0053] During the inspection, the inspection data visualization log management unit (14) displays hydraulic sensor data and judgment results received from the integrated inspection device (1) in real-time in the form of graphs and tables as shown in FIG. 2. In the graph area, changes in hydraulic sensor measurements are displayed in real-time based on the time axis, and the reference value set by the external equipment linkage inspection condition setting unit (13) is displayed together as a reference line, so the operator can visually identify the deviation between the measurements and the reference value immediately. In the table area, measurements and pass / fail judgment results for each inspection item, such as hydraulic pressure, response speed, and temperature, are displayed, making it possible to check the results for multiple inspection items at a glance. For example, if the hydraulic pressure measurement value is 1487N, which is within the allowable error range of 1425N to 1575N of the reference value of 1500N, the judgment result may be displayed as pass, and if the temperature measurement value is outside the allowable range, the judgment result may be displayed as fail.

[0054] If the communication processing unit (12) detects a communication error with the integrated inspection device (1) during the inspection, the error status is immediately displayed on the communication status panel, so the operator can recognize this and stop the inspection by operating the test stop button and check the communication connection status. Once the communication error is resolved, the operator can resume the inspection by operating the test start button again.

[0055] When measurements for all inspection items are completed, the operator operates the test stop button to end the inspection. When the inspection is finished, the inspection data visualization log management unit (14) automatically saves the inspection log, which includes the product identification information, inspection items, inspection date and time, applicable criteria, and judgment results collected during the inspection, in a file or database format. Since the saved inspection log is classified and managed by product identification information, if after-sales service for the same product is required later, the operator can quickly analyze the cause of the defect by querying past inspection logs based on the product's identification information to identify abnormal signs in the measured values ​​for each inspection item, such as hydraulic pressure and response speed, and the timing of changes in the judgment results.

[0056] In this way, the user interface device (10) according to the present invention can consistently perform the entire inspection procedure, from selecting inspection items and setting inspection conditions to starting inspection, displaying real-time data, and saving inspection logs, in a standardized manner within a single screen system, thereby reducing variations in the inspection procedure depending on the operator and increasing the efficiency and reliability of inspection work throughout the lower limb assembly and manufacturing process and after-sales service process.

[0057] In the foregoing, although all components constituting an embodiment of the present invention have been described as being combined or operating in combination, the present invention is not necessarily limited to such embodiments. That is, within the scope of the purpose of the present invention, all components may be selectively combined in one or more ways to operate. Furthermore, terms such as "include," "constitute," or "have" described above, unless specifically stated otherwise, mean that the relevant component may be inherent; thus, they should be interpreted as allowing for the inclusion of additional components rather than excluding other components.
