| 摘 要： | 针对提高被动式热释电红外(PIR)传感器的探测距离和范围,提出动/静态双坐标感知系统理论,根据动/静态双坐标感知系统对动态目标实现一定距离内和全范围探测的要求,光学基准传递的要求,提出了小型动/静态双坐标感知系统的结构设计方案。该系统配用红外透镜作为其光学装置,在匀速转台的带动下,实现360°全范围探测红外信号,解决了PIR传感器探测距离和探测视场的矛盾,拓宽了PIR传感器的使用领域。经过实验验证,该系统结构设计合理。

| Abstract: | To improve detection distance and scope of passive pyroelectric IR （ PIR ） sensor, according to requirements of dynamic/static double coordinates perceptual system for dynamic target realization within a certain distance and full range of detection, put forward structure design sncheme of small dynamic/static double coordinates perceptual system. The system is equipped with infrared lens as optical device, in uniform turntable drive, realize 360° full range detection of infrared signal. Solve contradiction between PIR sensor detection distance and field of view, widening application field of pyroelectric sensor. Experimental results show that the design of system structure is reasonable. |
