摘　　要：目的研制在实验室和野外现场实时测量人体心电、体温等多项生理指标的遥测仪器。方法将计算机作为遥测处理终端，系统采用频－时分混合调制方式，慢变数据解调后直接从计算机串口输入，它的测量、控制采用单片机实现，温度测量采用计算机查表法进行测量转换。结果本机能实时遥测、处理心电、体温、风速及多点皮温。在－１７℃以及实验室高温条件下（４５℃）实际使用，仪器运行良好，取得满意的结果。结论本机具有处理功能强、测量精度高、工作可靠性好、作用距离远、体积小、操作简便等特点。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℃ environment. Conclusion The instrument has many advantages, such as high accuracy, good processing ability, reliability, long operation distance, small volume and easy operation.
