Existing electrocardiogram (ECG) data processing systems face challenges in accurately transmitting and displaying ECG data due to transmission delays, which can distort heart rate readings and other vital information, potentially leading to misdiagnosis in heart conditions.
Innovation Solution
A bio-signal data processing apparatus and method that includes a communicator to receive ECG data, a recording unit to record the data, a transmission delay determiner to calculate delay information, and an output information generator to compensate for transmission delays by adjusting the time axis of the ECG data, ensuring accurate heart rate calculations and user input adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If ECG data is transmitted from the measuring apparatus to the processing apparatus, then the data can be processed and displayed, but transmission delays occur that distort heart rate readings and vital information
Solution Approach 1:
The system performs preliminary actions by recording the transmission start time at the measuring apparatus and the reception time at the processing apparatus before any processing occurs. This allows the delay to be calculated and compensated for in advance, ensuring that heart rate readings are corrected before display, thus resolving the contradiction between maintaining measurement precision and accounting for time loss during transmission.
2Reliability
If the ECG data is processed in real-time with delay compensation, then accurate heart rate readings are achieved, but the system complexity increases due to additional processing steps
Solution Approach 1:
The system segments the delay compensation process into distinct functional modules: a transmission delay determiner that calculates delay based on recorded timestamps, and an output information generator that applies the compensation to generate corrected ECG data. This segmentation allows each module to perform a specific function independently, making the overall system more manageable and maintainable while ensuring reliable diagnostic accuracy through systematic delay correction.
3Measurement precision
If transmission delay compensation is applied to all ECG data, then diagnostic precision is enhanced, but the processing time and computational resources increase
Solution Approach 1:
The system changes the time parameter of the ECG data by calculating the transmission delay based on recorded timestamps and adjusting the output data accordingly. This parameter transformation allows the system to maintain high diagnostic precision by correcting time distortions while using efficient algorithms that minimize computational overhead, thus preserving productivity despite the additional processing step.

AI summary
A bio-signal data processing apparatus includes a communicator configured to receive electrocardiogram data from a bio-signal measuring apparatus, a recording unit configured to record the electrocardiogram data, a transmission delay determiner, and an output information generator. The transmission delay determiner is configured to generate transmission delay information by comparing a recording time of the electrocardiogram data with a reception time of the electrocardiogram data, detect whether or not a delay according to data transmission occurs, by considering the transmission delay information, and, when the delay is detected to occur, calculating delay time information that is calculated on the basis of the transmission delay information. The output information generator is configured to correct the electrocardiogram data by using the delay time information and generate output data of the electrocardiogram data corresponding to a user input.
