The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
The utility model provides a kind of laser induced self interlocking damper control, and in Fig. 1,6 body of wall 3 other generating laser 1 and the laser pickoffs 2 installed relatively are equipped with red, green, yellow signal lamp 7 on air door 4 in the tunnel; Generating laser 1 and laser recipient 2 are connected respectively to main control box 5.
Figure 2 shows that the generating laser basic circuit diagram, this generating laser connects the input of 7805 Voltage stabilizing module IC9 by+12V voltage, and the output of IC9 connects laser diode LS and forms.+ 12V, earth terminal link to each other with master control borad+12V, earth terminal, and+12V power supply is laser diode LS power supply after three-terminal regulator block 7805 is reduced to+5V voltage through 10 Europe current-limiting resistances, and laser diode LS is subjected to electricity back emission laser.
Figure 3 shows that the utility model laser pickoff basic circuit diagram, it is 324 IC10 module that this laser pickoff adds to model by+12V voltage, be connected at output motherboard circuit trigger IC2 input triggering 1, trigger 2.+ 12V, earth terminal and trigger end.Because of the air door rear and front end all being installed by Laser emission and receiving system, so, two trigger ends are arranged on the master control borad, its operating principle is identical.With master control borad+12V earth terminal and trigger end link to each other.
Figure 4 shows that the whole control circuit schematic diagram of the utility model.Motherboard circuit is installed in Main Control Tank 5, power transformer connects three-terminal voltage-stabilizing module I C1 through bridge rectifier, IC1 one tunnel output meets control circuit IC6, IC7 and the IC8 of red greenish-yellow signal lamp 7, another road is the control circuit IC5 that is connected to behind 10 kilo-ohms of electric resistance partial pressures in the motherboard circuit, its output termination executive circuit module I C3, IC4.The output interlocking 1 of IC3, IC4, interlocking 2 are connected to the executing agency of air door 4.
Principle of the present utility model is as follows, and 660V or 380V alternating current become 127V and two groups of alternating currents of 15V through transformer.127V provides power supply for indicator lamp before and after the air door, and 15V is control circuit, Laser emission, receiving circuit power supply through bridge rectifier, the stable 12V direct current of three-terminal voltage-stabilizing output.The laser that generating laser 1 sends, after the light-sensitive element of laser pickoff 2 receives, positive potential of 1 pin output of IC 10 modules, it is luminous to promote luminous tube, and 7 pin of IC10 module are control signal of trigger end output through 2K Europe resistance simultaneously.At this moment the signal of this trigger end makes master control borad be in stable duty through master control borad.Air door is closed, red light before and after the air door is bright, when the laser sensor before and after people or the object process air door, blocked the path of laser, light-sensitive element on the dash receiver does not receive laser signal, signal of IC 10 modules 1 pin output on the dash receiver, luminous tube on the dash receiver is extinguished, 7 pin of IC10 module are also exported a triggering signal simultaneously, the control master control borad makes master control borad transfer unsteady state to by original stable state, door opening, red light before and after the air door goes out simultaneously, green light is bright, shows that people or object can pass through this air door, control signal of the end of interlocking simultaneously 1 (the interlocking end is the locking line of adjacent air door) output, this control signal is controlled adjacent air door interlocking end 2, makes adjacent air door locking.At this moment the red light before and after adjacent this air door goes out, and amber light is bright, shows when people or thing will be through this road air doors need wait until after adjacent air door is closed and can pass through.Even at this moment have people or object to block the generating laser or the laser pickoff of this group air door, this air door can not opened yet.
When people or object by behind the air door, after the time-delay in 10～50 seconds (delay time can according to the actual conditions adjustment), air door is closed automatically.Green light before and after the air door goes out, and red light is bright, and circuit presents stable state again.At this moment interlocking end 1 is exported a control signal again, controls adjacent air door interlocking end 2, and the amber light of these adjacent air door front and back is gone out, and red light is bright, and air door possesses open function.
This circuit has memory function, when air door is in blocking, that is to say when amber light is bright, someone or thing block the laser sensor of this air door, this group air door just can not opened, and after another adjacent group air door is closed (amber light goes out), people or object are even without the laser sensor that blocks this air door, this air door also can be opened after another adjacent air door is closed voluntarily, realizes the locking of adjacent air door.
