Abstract
Disclosed are an optical signal communication method and device and a biometric data monitoring system using the optical signal communication method and device. An optical signal communication method performed by an optical signal transmitting device includes receiving current input data to be modulated into an optical signal, dividing the received current input data into a plurality of sub-data sets including first sub-data and second sub-data, modulating the current input data into an optical signal including a start pulse, an intermediate pulse, and an end pulse based on the sub-data sets, and transmitting the optical signal to an optical signal receiving device.

An optical signal communication method performed by an optical signal transmitting device, the optical signal communication method comprising:
- receiving current input data to be modulated into an optical signal;
- dividing the received current input data into a plurality of sub-data sets comprising first sub-data and second sub-data;
- modulating the current input data into an optical signal comprising a start pulse, an intermediate pulse, and an end pulse based on the sub-data sets;
- and
- transmitting the optical signal to an optical signal receiving device,
- wherein, when the optical signal receiving device does not receive at least one of the intermediate pulse and the end pulse from the optical signal transmitting device after the optical signal receiving device receives the start pulse and reaches a time count corresponding to a threshold value, the optical signal receiving device is configured to determine not to demodulate the received optical signal.
An optical signal communication method performed by an optical signal transmitting device, the optical signal communication method comprising:
- receiving current input data to be modulated into an optical signal;
- and
- modulating the current input data into an optical signal and transmitting the optical signal when a difference in value between the current input data and previous input data is greater than a threshold value, and not transmitting the current input data when the difference in value between the current input data and the previous input data is less than or equal to the threshold value,
- wherein the transmitting the optical signal comprises transmiting the optical signal to an optical signal receiving device based on a preset transmission period shared between the optical signal transmitting device and the optical signal receiving device.
A biometric data monitoring system, comprising:
- an implantable device configured to be inserted in a body of a target from which biometric data is to be collected, collect the biometric data, modulate the biometric data into an optical signal of a near-infrared light wavelength, and transmit the optical signal to an external optical receiver outside the body;
- the external optical receiver configured to detect the biometric data from the received optical signal outside the body of the target and transmit the detected biometric data to a remote biometric data collector;
- and
- the remote biometric data collector configured to transmit the received biometric data to a server.
