中文摘要：

根据热释电红外传感器的工作原理和特性，设计了一种红外传感器信号的采集探测实验方法。由于敏感元件在传感器阵列的四面，故设计圆周运动的探测方法。实验结果证明：本探测方法与采集系统采集红外信号良好，实验方法具有重要实用价值。

英文摘要：

According to the principle and characteristics of pyroelectric infrared sensor operation,a way to detect infrared sensor signals is designed. Because of the sensitive components are in the four sides of the sensor array, so the detection method of circular motion is designed. There show positive results on the method and acquisition system collects infrared signals after testing, it also proves this test method has critical practical value.
