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 a telemetry system for real-time measurement of a variety of physiological indexes such as ECG and temperature in the laboratory and field. Methods The computer is used as the telemetry processing terminal. The system adopts the frequency-time mixed modulation method. The slow-change data is input directly from the serial port of the computer after its demodulation. The measurement and control of the data are realized by single chip microcomputer. The temperature measurement adopts the computer look-up table method to measure and convert. Results The machine can real-time telemetry, ECG, body temperature, wind speed and more skin temperature. In -17 ℃ and laboratory conditions of high temperature (45 ℃) the actual use, the instrument works well and achieve satisfactory results. Conclusion This machine has a strong handling, high accuracy, good reliability, long range, small size, easy operation and so on.
