Microwave infrared double detector and alarming method thereof for personnel intrusion detection

Abstract

The invention relates to a microwave infrared double detector and an alarming method thereof for personnel intrusion detection. The technical problems that an existing double detector is single in adaptive host, cannot directly drive a warning circuit, and is simple in adaption scene and not obvious in warning lamp are solved. The microwave infrared double detector can directly drives an externalalarming circuit, can adapt to multiple kinds of alarming hosts, meets detection needs in different scenes, and is obvious in display effect. The microwave infrared double detector is provided with asingle-chip microcomputer controller, an ISP program loading port, a voltage stabilizing module, a pulse modulator, an X-wave band radar probe, an infrared sensor, a pulse modulator and a four-operational amplifying circuit. A power driving circuit is further arranged, the power driving circuit is controlled by the single-chip microcomputer controller, and the power driving circuit can directly drive an external alarming circuit of 12V1A to the maximum. The microwave infrared double detector can be widely applied to detecting human bodies entering a defense area and outputting an alarm.

Description

technical field [0001] The invention relates to the technical field of electronic information, in particular to a microwave and infrared dual-detection detector and a method for detecting and alarming personnel intrusion. Background technique [0002] In recent years, with the improvement of residents' awareness of security, Shuangjian detectors are more and more widely used. Shuangjian detector can be used in the field of security, and can detect the human body entering the defense area and output an alarm signal to notify the upper alarm host. [0003] The usual dual-detection detectors have the following defects: 1. Only one alarm host can be adapted. When different detectors output an alarm signal, the circuit must be adapted to the corresponding alarm host. If it is used incorrectly, it may cause an error in the output of the alarm state; 2. There is only one alarm prompt method of indicator light. If there are other alarm functions, it needs to be realized through the...
