摘要
这里设计的红外信号检测开关目的是实现当人体接近红外信号检测装置时,依据信号处理结果自动开启负载,如果人不离开且在活动,负载持续工作,直至人离开后延时并关闭负载。该设计采用四元热释电红外信号处理器实现,并给出其完整的硬件电路设计方案。最后利用仿真软件Matlab进行了仿真。
The infrared signal examination switch is designed to achieve when the human body close to infrared signal de tectors,the load is opened automatically according to signal processing results,if the human does not leave also is moving,the load works continually,after until the human leaves the time delay and closes the load. This design uses four unit pyroelectric infrared signal processor,and its integrity hardware circuit design plan is given. Finally the simulation using simulation software Matlab.
