摘要
针对红外探测误报的问题,引入微波探测技术和单片机构成三鉴智能探测器。首先介绍三鉴智能探测器的基本原理结构,紧接着又给出被动红外信号调理电路和微波信号调理电路,然后介绍使用单片机实现探测器智能化的流程图。通过硬件电路设计和软件流程的实现并实施实验,验证了利用单片机实现智能化的可行性,并进一步降低了探测器的误报。
This paper introduces three heads intelligent detector composing microwave detecting technology and single chip computer in order to solve infrared false alarm. It presents the basic principle structure of this detector,and presents signal circuits of passive infrared detector and microwave. Then the flow chart of detector intelligence with single chip computer is introduced. The test is carried out after hardware circuit and software flow chart are designed. The feasibility that single chip computer is intelligent is turned out by means of the test.
