Embodiment

The circuit connecting mode of microwave-type alarm probe 1 as shown in Figure 1, its circuit working principle is: it is by doppler effect sensors IC ₁Produce microwave signal, wire loop is wirelessly transmitted to the space from 1,2 pin outside, forms principal space microwave fence on, when walking about in the people is netting, launches back wireless microwave signal and former transmitting will produce frequency displacement from human body, and IC is passed through in this frequency displacement ₁Internal monitoring amplifies, from 6 pin output ultra-low frequency signal, and through IC _2-1Be sent to primary input IC after the amplification _2-2, IC _2-3The window voltage comparator of forming, the signal voltage that probe is sent here compares discriminating, IC _2-4Be anti-phase comparator, its output low level triggers IC ₃, IC ₃Form and singly move delay circuit, IC ₃3 pin output high level trigger VT ₁Conducting starting relay K ₁

The circuit of infra red type alarm probe 2 as shown in Figure 2, its circuit working principle is by IC ₄Heat is released the thermal infrared radiation line that infrared sensor detects human body, and exports faint AC signal (0.3-10Hz), this a signal conveys IC that changes according to physical activity frequency size ₅8 pin, IC ₅Be the special signal processing integrated circuit, it has repertoires such as high letter rate linear amplification, two innings of amplitude discriminations, signal processing, delay timing, blockade timing, and signal after treatment is from IC ₅16 pin output high level signal P ₁, trigger main frame IC ₈And relay K ₃Work.

The circuit of touch-type alarm probe 3 as shown in Figure 3, its operation principle is: by TV ₂, the transformer feedback formula oscillator formed such as T, in running order at ordinary times, when key inserted lockhole, human body sensing added a very important load and makes VT to oscillator ₂Failure of oscillation, VT ₂Emitter current increases, VT ₃C is given in conducting ₁₆Charging VT ₄Base potential descends gradually, if open door lock less than limiting time, extracts key, does not have human body sensing, VT ₂Again starting of oscillation, VT ₃End C ₁₆Stop charging, VT ₄Conducting K not ₂Can not start; Improper in this way unblanking surpasses limiting time, VT ₄Base potential continues to descend VT when reaching the 0.7V left and right sides ₄Conducting K ₂Startup work, circuit alarm.
