摘　　要：为了适应医学的发展,研究红外线人体测温技术具有实际的意义。阐述了红外线测温原理,对如何减小测温误差进行了讨论,同时进行了红外线人体测温系统设计。在分析红外线传感器和A/D转换对测量精度影响的基础上,选择PM611单元热释电传感器和ICL7106积分式A/D转换器等器件实现了一种误差较小的红外线人体测温电路的设计,达到了预定的设计效果。For the development of advanced medicine,it has practical meaning to research the technology of infrared thermodetector for medicine. The principle of infrared temperature measurement and the method of reducing error are introduced in this article. Based on them, the system design of infrared thermodetector for human body is described. On the basis of the analysis of effects on measurement accuracy from the IR sensor and A/D converting, the circuit design of infrared thermodetector for human body with less error is provided, using PM611 and ICL7106, which achieves prospective result.
