Abstract
OBJECTIVES
In order to devise the combination module transmitting bio signal and signal data remotely, as defect of wirewireless combination module was complemented by designing a single combination of wireless module and power supply module, a single system was implemented.
METHODS
Currently in case of wireless transmission, it had various problems causing by some factors such as buildings, obstruction, and entanglement of wires and so on. In order to overcome problems of wireless transmission, a single combination module design was researched, which transmits vital signal and sign data using basic electric line installed in the inner building or between others. Even though it was also possible of wireless communication and the internet, in case of a power supply without them, it could be possible to transfer data to underground or top ground in the inner building without any special communication line.
RESULTS
Bio signal data was transmitted through a power supply line, a noise problem occurred would be solved by the designed noise filter. The filter showed that noise was cut off about more than 90%. It was also confirmed that the used ECG signals was stably received on transmission experiment. An internal PCB antenna could make the system be wireless communication without the disclosure of an antenna.
CONCLUSIONS
In this study, in order to implement a useful system transmitting bio signal and data through wire and wireless management for combination design of wireless module and electrical line module, bio signal transmission system was implemented by design of noise break filter circuit to reduce power noise and PCB internal antenna design.
