摘　　要：本文叙述了一种利用热电堆探测器的红外测温仪。依据黑体辐射定律导出了关系式。通过引入单片机的软件实现了仪器的智能化。从而使仪器的调试方法简化,利用简易设备即可达到较高的标定精度。仪器不需要调制与恒温系统,故结构简单轻便、使用方便、价格低廉。除适用于植物叶片及群体温度测量外,也可广泛用于其它物体表面温度的测量。This article has dealt with a sipmle infrared thermometer by useof thermopile detector.According to the relational expression derived from theperfect radiation law and by the way of software of single microprogram un-it,a kind of intelligent instrument has been realized so as to simplify thedebug program of the instrument.Quite high rating precision may be gainedwith simple equipment.This instrument does not need the systems of modul-atioa and thermostat so that its structure is simple and weight is light.It iseasy to operate and cheaper in price but with high precision(0.2C).This instrument is most suitable for measuring the temperature of plant le-aves and other objects in agricuIture,even it may be widely used for measur-ing the surface temperature of other objects.
