Abstract
OBJECTIVE
To develop an instrument used in measurement of physiological parameters in laboratories or field. Method A: computer was used to process data in the telemetry system. The frequency-time division modulation technique was adopted. The low frequency signals were directly connected to the computer serial port after demodulation, and measurement control was achieved by single-chip computer. Temperature measurement results were obtained by conversion table.
RESULT
It is capable of telemeter and processing ECG, wind speed and temperature signals in real-time. Good results were gained in high temperature condition and -17 degrees C environment.
CONCLUSION
The instrument has many advantages, such as high accuracy, good processing ability, reliability, long operation distance, small volume and easy operation.
