Description
Technical field
The invention belongs to electronic auto-control technology field, it is related to a kind of wind curtain machine human body close to automatic control switch.
Background technology
Wind curtain machine is to drive the airflow that through-flow or centrifugal wind wheel generate by high-speed electric expreess locomotive, above door body by upper and
It is lower to form the invisible wind door curtain of one side.
Indoor and outdoor can be divided into two independent temperature regions by the air-flow that wind curtain machine generates high speed, produce comfortable indoor ring

Invention content
Goal of the invention and advantageous effect：Because the motor electric power of wind curtain machine is generally larger, wind curtain machine of the present invention
Commonly there is the high defect of operating cost close to automatic control switch, for wind curtain machine in human body, specially devise one kind and working as human body
When wind curtain machine above close to door body, whether operation by human body induction control wind curtain machine, it is automatic in the way of human body sensing
Whether identification door body nearby has human body, once far from wind curtain machine, it can be delayed to run more than ten seconds and just be automatically stopped human body.This hair
The bright succinct, reliable working performance with circuit design structure, circuit is all using the making of ordinary electronic component, cheap etc.
Advantage.
Circuit operation principle:Wind curtain machine human body is one close to automatic control switch core circuit and is in shaking for critical condition
Circuit is swung, when there is human body close to oscillator coil L (inductive probe), the oscillation of oscillating circuit is made of elements such as oscillator coil L
Frequency will great changes will take place so that and the Q values of oscillator coil L reduce, and force the oscillating circuit failure of oscillation in threshold oscillation state,
And then wind curtain machine motor is controlled by related circuit and automatically turns on or closes.
NPN type triode BG1 and oscillator coil L, oscillating capacitance C1, oscillating capacitance C2 constitute bikini and shake in circuit
Swing circuit.When the base stage of NPN type triode BG1 in oscillating circuit has a positive signal, since the inverting function of triode makes NPN
The collector signal of type triode BG1 is negative.The signal polarity at the both ends of oscillating capacitance C1, oscillating capacitance C2 be it is upper just under
Negative, signal makes the signal in NPN type triode BG1 base stages and original signal same-phase, because being just by the feedback of capacitance C3
Feedback, so circuit will produce oscillation, the potentiometer RP of access can weaken positive feedback signal intensity in circuit, for adjusting circuit
The critical value of starting of oscillation.

Capacitance C2 is determined.The size of positive feedback signal can be controlled by adjusting potentiometer RP, and adjusting potentiometer RP makes oscillating circuit be in rigid
It shakes state.Resistance R1 is the biasing resistor of NPN type triode BG1.Faint oscillator signal is sent to NPN type by coupled capacitor C4
Triode BG2 carries out oscillating voltage amplification.Because amplified oscillating voltage amplitude is still smaller, therefore select two germanium material detections

DC voltage can make NPN type triode BG3 work normally, at this moment the collector of NPN type triode BG3 is in low level, directly
Current relay J coils obtain it is electric so that contact is attracted, i.e.,：The normally-closed contact J-1 of DC relay J is disconnected, and makes wind curtain machine motor M dead electricity
It shuts down.
When there is human body close to oscillator coil L, the oscillating circuit failure of oscillation immediately in oscillation critical condition passes through and couples electricity
Holding the oscillating voltage of C4 will disappear, and the base stage of NPN type triode BG3 cannot get forward voltage, and NPN type triode BG3 is made to end,
And DC relay J coil losing electricities contact is made to discharge, i.e.,：The normally-closed contact J-1 of DC relay J is connected, and makes wind curtain machine motor M
Obtain electric start running.
Due to having accessed filter capacitor C6 in multiplication of voltage detection and filter circuit, it has filtering and delay double action concurrently.Filter
Wave capacitance C6 is required to one section of transfer process in charge and discharge, if its Capacity Selection is appropriate, can just obtain about 15 seconds
The delay time of clock, when realizing human body far from oscillator coil L, wind curtain machine motor M can be delayed operating requirement in more than ten seconds.
