Description

ELECTRONIC DEVICE FOR SYNCHRONIZING TIME OF RECEIVED DATA RECORDS AND METHOD THEREOF

Various embodiments disclosed in this document relate to a method for synchronizing the time of received data with an electronic device.

Recently, as the demand for health management increases, sensors for measuring various biosignals are being used in electronic devices. Representatively, sensors such as a pulse sensor, a heart rate sensor, a check sensor, an electrocardiogram (ECG) sensor, and a photoplethysmography (PPG) sensor may be used. The above sensors may be provided in the electronic device, and the user may continuously check the biosignal measured by the sensor using the electronic device.

As the scalability of sensor technology is in the spotlight and digital data processing technology grows, the collection of sensor signals is mostly done by digital signal acquisition systems, and high-speed collection is required to increase the resolution of information.

In digital signal acquisition, two or more digital signal acquisition systems are used to simultaneously acquire signals for the purpose of performance comparison, accurate signal measurement, or safe signal acquisition. In collecting bio-signals, various bio-signals such as ECG, PPG, movement, and body temperature generated in the body can be simultaneously collected using different digital bio-signal measurement systems. In the analysis of the simultaneously collected data, time synchronization between the collected data may be required. For example, in order to observe the change in the PPG signal when the ECG signal shows abnormal symptoms, it is necessary to view the time-synchronized PPG signal with the ECG signal at the abnormal time point. A function that can synchronize the starting point of a signal such as a slate between digital data requiring time synchronization is required.

Digital signal acquisition systems typically provide various sampling frequencies for signal acquisition, such as 25Hz, 100Hz, 256Hz, and 500Hz. However, this sampling frequency may have errors depending on the design and implementation of the system. Due to this error, even if the start points of signals are synchronized between digital data, there may be a gradually larger time difference between subsequent signals as time goes by. Therefore, when continuous signal collection for a long time is required, there may be a need to periodically perform synchronization between the beginning and the end, or as needed, rather than synchronizing only the start time.

An electronic device according to various embodiments disclosed in this document includes a communication module for communicatively establishing a connection with at least one external electronic device, and a processor operatively connected to the communication module, The processor receives a first sample ID (identification) corresponding to the first sample data collected by the external electronic device and a second sample ID corresponding to the second sample data, and when the first sample ID is received A corresponding first time and a second time corresponding to the reception time of the second sample ID are identified, and the first sample data and the second sample data are at least included from the external electronic device, and the first sample data and a time required for receiving sensor data including a plurality of sample data other than the second sample data, and being a time interval between the first sample data and the second sample data based on the first time and the second time and calculating the sampling period information of the sensor data based on the calculated required time and a plurality of sample data other than the first sample data and the second sample data.

A data synchronization method of an electronic device according to various embodiments disclosed herein includes receiving a first sample ID (identification) corresponding to first sample data and a second sample ID corresponding to second sample data from an external electronic device. operation, confirming a first time corresponding to a reception time of the first sample ID and a second time corresponding to a reception time of the second sample ID, and the first sample data and the second sample from an external electronic device receiving sensor data including at least data and including a plurality of sample data other than the first sample data and the second sample data, the first sample data based on the first time and the second time and calculating a required time that is a time interval between the second sample data, and a sampling period of the sensor data based on the calculated required time and a plurality of sample data other than the first sample data and the second sample data. It may include the operation of calculating information.

According to various embodiments, time synchronization between the received data may be performed by receiving digital signals generated from two or more different electronic devices. Therefore, it is possible to improve the accuracy of the comparative analysis of the simultaneously received data, and the efficiency and stability of the system can be expected.
