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

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further to describe.

Like Fig. 1, shown in Figure 2; A kind of new type auto controlling device for doors of the utility model; Comprise infrared sensing circuit 1, fault triggering circuit 2, single chip machine controlling circuit 3, automatic door drive circuit 4, carrier signal phase lock circuitry 5, frequency-selective amplifier circuit 6 and carrier signal decoding circuit 7; The output signal of said infrared sensing circuit 1 is sent to automatic door drive circuit 4 through single chip machine controlling circuit 3 controls; The output signal of said fault triggering circuit 2 is sent to carrier signal phase lock circuitry 5 through single chip machine controlling circuit 3 controls, and the output signal of said carrier signal phase lock circuitry 5 is sent to carrier signal decoding circuit 7 through frequency-selective amplifier circuit 6.

Said infrared sensing circuit 1 is made up of potentiometer RP1, the resistance R 1 that HN911D rpyroelectric infrared sensing module IC and output thereof connect; Down static; Be that HN911D rpyroelectric infrared sensing module IC is not when receiving the infrared energy that mobile human body gives off; Whole module remains static, and its 1st pin output is low level, and its 2nd pin is high level.

As the people when automatic door is come up and get in the detecting area of HN911D rpyroelectric infrared sensing module IC, HN911D rpyroelectric infrared sensing module IC just to the infrared signal that detected human body radiation goes out amplify, after filtering, comparison and signal handle, its 1st pin output is transmitted high level; Through resistance R 1 current limliting, the 32nd pin I/O port that is input to single-chip microcomputer IC3 also is high level, after single-chip microcomputer IC3 internal judgment; The 28th pin output triggering signal by single-chip microcomputer IC3 through resistance R 3 current limlitings, makes the controllable silicon SCR triggering and conducting; Motor gets electric, opens automatic door, behind single-chip microcomputer IC3 internal delay time; Send triggering signal again, the motor counter-rotating is closed to the doorstep.

Said fault triggering circuit 2 by the switch T1 output that is connected in the motor rotating mechanism connect resistance R 4 successively, photoelectrical coupler IC4 constitutes; When motor rotates; But the automatic door rotating mechanism does not rotate thereupon and blocks or during mechanical breakdown, supply voltage is in normal battle through the switch T1 that is connected in the motor rotating mechanism, and photoelectrical coupler IC4 does not have the light source optocoupler because of inside and is in not on-state; Therefore single-chip microcomputer IC3 the 23rd pin is in high potential state; After single-chip microcomputer IC3 internal processor is judged, send control signal, form carrier signal phase lock circuitry 5 by the multivibrator that LM567 tone decoder IC1 and peripheral electric capacity 2C1, resistance 2R1, resistance 2R2 thereof constitute; Its frequency of oscillation is by the parameter determining of electric capacity 2C1, resistance 2R1; Carrier frequency is adjusted in the 150-300KHZ scope, constitutes frequency-selective amplifier circuit 6 by primary inductance L1, electric capacity 2C2, the capacitor 2C3 of triode VT1, audio-frequency transformer T, by single-chip microcomputer IC3 the 26th pin output high level signal; Make LM567 tone decoder IC1 obtain triggering signal; LM567 tone decoder IC1 starts working, and is coupled on the AC network AC220V power line and is sent by secondary inductance L2, the electric capacity 2C4 of audio-frequency transformer T, sends data-signals to the carrier signal decoding circuit 7 of carrier wave main frame.
