Abstract

The utility model relates to an intelligent anti-theft detector comprising an infrared induction detection circuit and a microprocessor control circuit. Output signals of the infrared induction detection circuit are controlled and sent to a ZigBee wireless module circuit and an alarming circuit through the microprocessor control circuit. The output signals of the ZigBee wireless module circuit are sent to a data process center. As a pyroelectric infrared sensor is adopted to collect the human body signals, the microprocessor control circuit judges and sends out signals of power failure, and the ZigBee wireless module circuit sends the alarming signals to an on-duty center, the intelligent anti-theft detector has the advantages of being long in distance and low in cost by means of honeycomb type networking.

Description

Intelligent pir intrusion detector

Technical field

The utility model relates to a kind of detector, particularly be a kind of intelligent pir intrusion detector.

Background technology

Modern society, security precautions technology is more and more important, particularly the working clan in the city; All in company's working, have only just go home evening, like this one day daytime; Thief's burglary of just may taking advantage of the occasion daytime though the guard is arranged in the sub-district, can only accomplish that also the people of the suspicion that prevents passes in and out the sub-district; Along with intelligentized progressively ripe, the burglar alarm on the market is more and more, but it mainly be radio alarming is main.

The utility model content

The purpose of the utility model is to provide a kind of intelligent pir intrusion detector that adopts honey formula relay alarm mode.

The utility model solves the technical scheme that its technical matters adopted: intelligent pir intrusion detector; Comprise infrared induction testing circuit and microprocessor control circuit; The output signal of said infrared induction testing circuit is sent to ZigBee wireless module circuit and warning circuit through microprocessor control circuit control, and the output signal of said ZigBee wireless module circuit sends to data processing centre (DPC).

Preferably, said infrared induction testing circuit is made up of the YX7603 IC 3 that pyroelectric infrared sensor TN output terminal connects.

Preferably, said microprocessor control circuit adopts single-chip microcomputer IC1 to be the control core.

Preferably, said ZigBee wireless module circuit adopts ZM2410 wireless communication module IC2.

Through adopting above-mentioned technical scheme; The beneficial effect of the utility model is: the utility model adopts pyroelectric infrared sensor to gather human body signal, and judge through microprocessor control circuit and send power-off signal, and through the ZigBee wireless module; Send alerting signal to center on duty; It adopts the honeycomb fashion networking, has distance, low cost and other advantages.

Description of drawings

Fig. 1 is the frame assumption diagram of the utility model;

Fig. 2 is the circuit theory diagrams of the utility model.

Embodiment

Like Fig. 1, shown in Figure 2; The intelligent pir intrusion detector of the utility model; Comprise infrared induction testing circuit 1 and microprocessor control circuit 2; The output signal of said infrared induction testing circuit 1 is sent to ZigBee wireless module circuit 21 and warning circuit 22 through microprocessor control circuit 2 controls, and the output signal of said ZigBee wireless module circuit 21 sends to data processing centre (DPC) 212.

Said infrared induction testing circuit 1 is made up of the YX7603 IC 3 that pyroelectric infrared sensor TN output terminal connects; When the people moves before pyroelectric infrared sensor TN; The voltage amplifier of detectable signal in the 6th pin of the defeated people YX7603 IC 3 of coupling capacitor C1 of pyroelectric infrared sensor TN output; First order voltage amplifier is adjusted Amplifier Gain and is prevented self-excitation through YX7603 IC 3 RSET R1 and capacitor C2; The defeated people second level of signal after amplification amplifier, can through external potentiometer W1 between the 17th, 18 pin of YX7603 IC 3 regulate monitoring human near oil pumper equipment near distance.Second level voltage amplifier is formed low frequency bandpass amplifier by YX7603 IC 3 CSET C5.Signal after the amplification is through voltage comparator and latch, after time-delay etc. handles, by the 13rd pin output low level of YX7603 IC 3, through resistance R 5 current limlitings, the 37th pin that is added to single-chip microcomputer IC1 is low level state; Judge to have people's illegal invasion, after the inner comprehensive judgement of single-chip microcomputer IC1, send control signal; First via output, the 26th pin output high level by single-chip microcomputer IC1 makes transistor VT1 conducting; It is electric that news Chinese percussion instrument BY is got, and sends alarm sound, frightens the robber away; The second tunnel output; Form ZigBee wireless module circuit 21 by the 6th, 7 ends of ZM2410 wireless communication module IC2 and the 10th, 11 ends of single-chip microcomputer IC1, ZM2410 wireless communication module IC2 is the embedded serial ports transparent transmission of the Zigbee of built-in 2.4GHZ (some multiple spot and point-to-multipoint) communications protocol, supports aerial upgrade firmware or configuration far module information; Receiving sensitivity up to output of the power of 7dBm and-100dBm; Can satisfy telecommunication, send the AT instruction by single-chip microcomputer IC1 ZM2410 wireless communication module IC2 is realized wireless data transceiving, switch pin with the RS-485 direction; Send current failure message to data center; This module is the honeycomb fashion networking, reaches distance, low cost and other advantages.

An above-described preferred embodiment that is merely the utility model can not limit the scope that the utility model is implemented, and every equalization of being done according to the utility model claim changes and decorates, and all should still belong in the scope that the utility model contains.
