The data receiver 112 may receive data sensed by the sensing device 120 . The data receiver 112 may receive the electrocardiogram data through an electric line. The data receiver 112 may receive the electrocardiogram data using a wireless or wired communication method.

The data converter 113 may transform the electrocardiogram data received from the sensing device 120 (wavelet transform). The data converter 113 may determine a current transmission characteristic based on communication quality information of a wireless channel with the data receiving device, and determine a data resolution corresponding to the transmission characteristic. The data converter 113 may convert a biosignal, for example, electrocardiogram data, according to a data resolution corresponding to a transmission characteristic. A typical example that determines communication quality is the characteristics of the physical layer. Usually, the communication quality information may include RF signal strength. In addition, the communication quality information may include time-variant and band-limiting characteristics, frequency selectivity, a modulation scheme that widens a bandwidth but consumes less power, delay dispersion information, and Doppler dispersion information.

The data conversion unit 113 designates a first correction scale or a first movement correction degree (translation) through a data resolution corresponding to the transmission characteristics, and provides a first correction size or a first movement correction degree for the biometric data such as electrocardiogram data. A signal can be wavelet transformed. In this case, a biosignal such as electrocardiogram data may be decomposed into a plurality of frequency components. In addition, the data converter 113 may decompose a biosignal such as electrocardiogram data into a plurality of data sections and convert each of the plurality of data sections to a bit scale. The bit scale may be determined by the pattern of the corresponding section.

The data conversion unit 113 designates a first bandwidth through a data resolution corresponding to a transmission characteristic, increases the resolution of the designated first bandwidth among components of a biosignal such as electrocardiogram data, and increases the resolution of the first bandwidth except for the first bandwidth. 2 It is possible to convert biosignals such as electrocardiogram data to lower the resolution of the bandwidth.

In this case, a biosignal such as electrocardiogram data may be decomposed into a plurality of frequency components based on bandwidths. In addition, the data converter 113 may decompose a biosignal such as electrocardiogram data into a plurality of data sections and convert each of the plurality of data sections to a bit scale.

The data conversion unit 113 determines whether a transmission delay occurs during transmission of the electrocardiogram data through the communication quality information of the wireless channel, and transmission characteristics such as the quality of the wireless channel (available wireless bandwidth, RF communication quality, etc.) can be measured. The data converter 113 may determine a data resolution capable of transmitting the biosignal without data loss in the transmission characteristics of the wireless channel. In this case, whether the transmission delay occurs may be determined by a feedback signal from the data receiving apparatus 200 . In this case, the feedback signal may be received from the data receiving apparatus 200 or may be obtained through a wireless channel with the data receiving apparatus 200 .

The data conversion unit 113 may make the transmission data size or capacity of the electrocardiogram data transmitted through the wireless channel small through this conversion. As the size of the transmitted data decreases, the electrocardiogram data may be transmitted to the external data receiving apparatus 200 without time delay even in an environment in which a transmission delay occurs. In another embodiment, the data converter 113 may convert a biosignal such as electrocardiogram data according to a communication control signal from the external data receiving device 200 .

When the residual capacity of the power supply unit 150 is equal to or less than a preset minimum capacity value, the data conversion unit 113 may convert a biosignal such as electrocardiogram data into a smaller transmission data size. When the transmission data size is reduced, the power required for one transmission of one transmission unit may be reduced based on the transmission unit of the ECG data. For example, the data conversion unit 113 may include transmission characteristics with the receiving device, that is, a communication protocol, a version of a communication protocol, a type of a communication network, transmission characteristics, transmission speed, specifications or performance of the receiving device 200 when transmitted. It is possible to reduce or increase the transmission data size of the electrocardiogram data in an environment in which a time delay or delay is generated.

The data conversion unit 113 converts the electrocardiogram data in consideration of transmission characteristics, state information of the power supply unit 150 , and state information of the data receiving device 200 .

The data converter 113 may store the electrocardiogram data as it is in the local memory without converting it. The data conversion unit 113 may perform a conversion process for transmission to a remote device after being stored in the local memory.

The data conversion unit 113 obtains a transmission time of the ECG data and a transmission completion time of the ECG data in consideration of the feedback signal from the data receiving device, and compares the transmission time of the ECG data and the transmission completion time of the ECG data to delay the transmission It is possible to generate information and detect whether a delay according to data transmission occurs in consideration of the transmission delay information. The transmission time may include information on when the electrocardiogram data is transmitted from the data receiving apparatus 200 . The transmission completion time may include information on the transmission time of the electrocardiogram data measured by the data receiving device 200 .

The electrocardiogram data may be converted into a transmission data size to be converted into one or more transmission data. In this way, the transmission data may be transmitted through one radio channel or may be transmitted in parallel or serially through a plurality of radio channels.

In order to increase transmission efficiency, the biosignal measuring apparatus 100 may compress the converted ECG data.

The transmission control unit 114 may transmit transmission data of the electrocardiogram data converted by the data conversion unit 113 to the designated data receiving device 200 . The transmission control unit 114 may transmit one or more transmission data selected from among the transmission data of the electrocardiogram data processed by the data conversion unit 113 .
