[Development of software system of medical monitoring equipment in spacecraft].
OBJECTIVE
To develop a software system that can gather, manage and transmit signals of electrocardiograms, respiration, body temperature and blood pressure at real time, in order to monitor physiological signals of astronauts.


METHODS
Based on single-chip microprocessor, software system completed the A/D conversion, real-time signal processing, storage and transmission.


RESULTS
The software system realized data acquisition of electrocardiogram, respiration, body temperature and blood pressure, as well as heart rate extraction from electrocardiogram, storage of physiological data, and transmission of physiological parameters to spacecraft.


CONCLUSIONS
The software system could meet the needs of medical monitoring during manned spaceflight.
