When infrared thermometer, and uses non-contact method of measuring temperature in medicine to regulate the infrared thermometer, ranging from ℃ to ℃accuracy should be ℃, which is used in medicine. But the thermometer Infrared can not achieve this regulation. Meanwhile the accuracy of the thermometer in the infrared this temperature range can be significantly affected by the error temperature of the surrounding environment also increased significantly.
After the search of large amounts of data, and disadvantages of infrared thermometer group medical, and a new way to compensate for the ambient temperature, and the principle of detecting electrical heat on the basis of this new way of paper. This proposed and determine the amount of compensation according to the temperature is measured at the difference between goals and ambient temperature surrounding. The programs address the digital chip. New ways to overcome the disadvantages of

thermal resistance.
In the process of designing infrared system, micro system simulation WAVE6000 control debugging and compiling programs, assembly language, because each part. The relationship between the timing of the testing measure infrared heat to improve the accuracy and stability, it can not already. But it couldn’t reach our country’s standards on medicinal thermometer.
Keywords: Infrared temperature measurement; Pyroelectric detector; Temperature compensation; Microcontroller

引言
〜1000μm之间，存在于自然世界的每一个角落。事实上，所有高于绝对零度的物体都保持着红外辐射。从内侧发射的红外线的材料，物质的运动产生红外线的来源。正如我们都知道，物质都是由分子，原子，他们正在按照一定的规那么，其运动状态也是不断变化的，因此继续辐射能量，这是热辐射的现象。红外辐射的物理性质是热辐射，这种辐射量主要决定于物体的温度和物料的性质，特别是，组合物中的热辐射的强度和光谱辐射体的温度取决于热辐射现象的温度[1]。
过去20年，可以毫不夸张地说，温度的检测是现代工业的命脉。红外测温技术在产品质量控制和监测设备在线故障诊断，平安，节能发挥了重要作用。温度测量的方法有两种类型，一种是利用电气参数随温度变化的
