Abstract

The utility model discloses an intelligent population flow detection door, belongs to the field of electronic equipment, and aims to overcome the shortcoming that the conventional population flow detection device cannot finish population detection within a short time and depends on a corresponding management system. The intelligent population flow detection door consists of two laser emitters, two laser receivers and a singlechip. Under the condition that the fixed door access habit of general people is not changed, people passing through the door can be quickly detected; and furthermore, the detected population flow data can be sent to display equipment in real time. The population flow can be detected in real time, and the fixed door access habit of the general people does not need to be changed; moreover, the detected population flow data can be conveniently displayed through a display device; and the intelligent population flow detection door is simple in structure. The intelligent population flow detection door is mainly suitable for libraries and other places where the indoor population needs to be reflected in real time.

Description

Intelligence number flow detection door

Technical field

The utility model belongs to electronic device field.

Background technology

At present, the device of known number flow detection is that radio-frequency card reader and radio-frequency card are formed.Radio-frequency card and radio-frequency card reader is close, read radio-frequency card information at short notice, record information.But such method can increase by the time, also can change the intrinsic custom of entering of general audient colony, and will rely on human factors such as corresponding management system.

Summary of the invention

The purpose of this utility model is to overcome existing number flow detector can not finish the intelligent number flow detection door that number detects and relies on the corresponding management system to cooperate in the short time.

The utility model is made up of two generating lasers, two laser pickoffs and single-chip microcomputer,

Generating laser: T1 launches laser signal, carries out signal through the Q1 triode and amplifies, and J1, R5, R6 form stabilizing circuit;

Laser pickoff: S1 is the receiving device of laser signal, and signal is transformed into electric signal through handling, and one of them receiver passes to the single-chip microcomputer central processing unit by OUT1, and another receiver passes to the single-chip microcomputer central processing unit by OUT2;

Single-chip microcomputer: 9 pin of central processing unit STC89C52 are connected with the reset circuit that KEY1, C1 form; 18,19 pin of STC89C52 are connected with the crystal oscillating circuit of C2, C3, X1 composition.

The utility model can not only detect the number flow through this under the situation that does not change the intrinsic custom of entering of general audient colony fast, and can be with real-time the sending on the display device of number data on flows that detects.The detection of carrying out the number flow that can be real-time need not change audient crowd's the intrinsic custom of entering simultaneously, and can easily the number data on flows that detects be shown by display device, and is simple in structure.Mainly be applicable to the real-time places of reflecting occupancy of needs such as library.

Embodiment

The utility model is made up of generating laser, laser pickoff and single-chip microcomputer,

Generating laser: mainly be by T1 emission laser signal, carry out signal through the Q1 triode and amplify, launch.J1, R5, R6 mainly play the effect of stabilizing circuit, prevent that laser sensor from burning out.

Laser pickoff: S1 is the receiving device of laser signal, and signal is transformed into electric signal through handling, and one of them receiver passes to the single-chip microcomputer central processing unit by OUT1, and another receiver passes to the single-chip microcomputer central processing unit by OUT2.

Single-chip microcomputer: 9 pin of central processing unit STC89C52 are connected with the reset circuit that KEY1, C1 form; 18,19 pin of STC89C52 are connected with the crystal oscillating circuit of C2, C3, X1 composition.OUT1 links to each other with the P2.7 pin, and OUT2 links to each other with the P2.6 pin.

The course of work:

At first, power on (i.e. all+5 and VCC among the figure) to system, after system powered on, laser transmitter projects pipe emission laser signal (i.e. T1 part among the figure) was to laser signal receiving tube (i.e. S1 part among the figure).If the laser signal receiving tube is if receive laser signal, then (namely the OUT1 among the figure OUT2) exports 1 P2.7 mouth, P2.6 mouth to single-chip microcomputer, if receiving tube does not receive laser signal, then exports 0 by output pin at this moment.Single-chip microcomputer is by judging that the signal receive is 0 or 1 to judge whether that the someone passes through like this.Under the situation that normal nobody passes through, P2.7, P2.6 mouth receive 1, when the people passes through, if the P2.7 mouth receives 0 earlier, think that then the someone enters, and the single-chip microcomputer counting adds one, receives 0 earlier as if the P2.6 mouth, thinks that then the someone goes out, and the single-chip microcomputer counting subtracts one.

The utility model is installed two LASER Discharge Tube in the middle part, two ends of doorframe in the middle of one end, two laser pickoffs are installed in the middle of the other end.The signal wire of receiver inserts single-chip microcomputer, handles that by single-chip microcomputer data are spread out of.The laser pickoff of outside does not receive the signal of LASER Discharge Tube emission earlier when the people enters intelligent number flow detection door, then receiving tube transfers data to single-chip microcomputer P2.7 mouth, think that then the someone enters intelligent number flow detection door, the display screen demonstration number that links to each other with intelligent number flow detection door adds 1, in like manner the laser pickoff of the inside does not receive the signal of LASER Discharge Tube emission earlier when the people leaves intelligent number flow detection door, then receiving tube transfers data to single-chip microcomputer P2.6 mouth, think that then the someone leaves intelligent number flow detection door, the display screen demonstration number that links to each other with intelligent number flow detection door subtracts 1.Very fast because of the response speed of laser sensor, be able to detect the purpose of number flow.So the detection of carrying out the number flow that can be real-time, the while need not change audient crowd's the intrinsic custom of entering.
