Brief description of the drawings

Fig. 1 is a kind of electrical block diagram of embodiment of the long-range key starting controller of the more equipment of meeting room of the present invention.

Embodiment

In order to be better understood from the present invention, illustrate with reference to the accompanying drawings and examples.

Embodiment：As shown in figure 1, the long-range key starting controller of the more equipment of the meeting room of the present embodiment includes binding post A0, binding post A1, binding post B0, binding post B1, binding post F0, binding post F1, binding post F2, binding post F3, rectifier bridge stack UR, integrated regulator IC1, switch K1, potentiometer RP1, resistance R2, resistance R3, resistance R4, electrochemical capacitor C2, electrochemical capacitor C3, non-electrolytic capacitor C1, non-electrolytic capacitor C4 ,+12V DC power supply E1, normally opened relay J, jack X1, insert Hole X2, jack X3, NPN type triode VT1 and diode D1；A0 is connected after UR ac input end series connection K1, UR's Another ac input end connects A1, and UR direct current output positive pole connects C4 one end and IC1 the 1st pin simultaneously, UR's Direct current output negative pole connects simultaneously after connecting the 3rd pin serial connection R2 of the C4 other end, IC1 the 2nd pin and F1, IC1 simultaneously Meet a RP1 definite value end and RP1 adjustable side, RP1 another definite value end connection F0；B0 connects X1 one end, X2 simultaneously One end and X3 one end, B1 connections J fixed contact, J normally opened movable contact connect simultaneously the X1 other end, X2 it is another End and the X3 other end；E1 positive pole connects C3 positive pole, D1 negative electrode, J iron-core coil positive pole and F2, E1 simultaneously Negative pole connects C3 negative pole, VT1 emitter stage, C2 negative pole, C1 one end and R4 one end simultaneously；D1 anode connects simultaneously J iron-core coil negative pole and VT1 colelctor electrode are connect, VT1 base stage connects C2 positive pole and R3 one end simultaneously, and R4's is another One end connects the R3 other end, the C1 other end and F3 simultaneously；Pass through wire between F0 and F2 and between F1 and F3 respectively Connection.

The IC1 can select 7812 type integrated regulator of the prior art.

The UR can be built from four IN4007 types diodes of the prior art.

The VT1 can select 2CS9013 types triode of the prior art.

The D1 can select IN4007 types diode of the prior art.
