The specific embodiment
Below in conjunction with accompanying drawing the present invention is further specified.The vibrating sensor of the following stated, photoelectricity are the commercially available prod near switch, MC33794 electric-field sensor, AT89C52 single-chip microcomputer and buzzer.
Vapour-pressure type intelligent anti-theft of the present invention exhibition booth; Through bolt universal wheel 7 is arranged below the base 8; Link to each other with the common cylinder 37 of the double-acting piston of pneumatic system 6 through bolt above the base 8, piston rod 24 upper ends of the common cylinder 37 of double-acting piston connect through the internal thread parafacies with the boss that is connected 26 lower surface centers, chassis, and the center that connects chassis 26 upper surfaces has a blind hole; Thrust ball bearing 25 is arranged in the blind hole; Be connected with the shaft shoulder of drive link 4 bottoms above the thrust ball bearing 25, the shaft shoulder of drive link 4 bottoms is fixed on the trapezoidal hole that connects end cap 27 lower surfaces, connects end cap 27 and is connected chassis 26 and is connected through bolt.DC speed-reducing 10 connects on the end cap 27 through being bolted to, and is connected with pinion 11 through key on the output shaft of DC speed-reducing 10, and the pinion 11 on the output shaft is meshed with gear wheel 12 on the drive link 4; Gear wheel 12 is connected on the drive link 4 through key, and the hole that exhibition booth case 1 base plate is passed in drive link 4 upper ends reaches exhibition booth case 1 inside, and the upper end of drive link 4 and exhibition dish 3 connect through the internal thread parafacies; Be pasted with rubber washer 13 on the exhibition dish 3; Nine electrodes of electric-field sensor are installed on the exhibition dish 3 around the rubber washer 13 uniformly, photoelectricity are installed near switch 14 in the centre bore of rubber washer 13, showpiece is placed on the rubber washer 13; Exhibition booth case 1 links to each other with pole 5 through screw thread pair; Insert in the slotted hole of ring flange the lower end of pole 5, and ring flange links to each other with base 8 through bolt, and case 1 top board inboard in exhibition booth is equipped with active plugboard mechanism 2; On four sides of exhibition booth case 1 inside vibrating sensor 15 is installed all; Open a side door 38 on one side of exhibition booth case 1, a side of side door 38 links to each other with casing through hinge, and the opposite side and the casing of side door 38 are equipped with door lock.
The center of active plugboard mechanism 2 case 1 top board in the exhibition booth is provided with two plates 16; Two plates 16 link to each other with slide block 19 through bolt, and slide block 19 is slidedly assemblied on two parallel guide rails 18, and two parallel guide rails 18 insert in the through hole of four guide rail bearings 17; And fix through screw; Guide rail bearing 17 is inboard through being bolted to exhibition booth case 1 top board, all is welded with a translation nut 23 on two plates 16, and screw rod 22 passes translation nut 23 and links to each other with shaft coupling 21; Shaft coupling 21 links to each other with corresponding stepper motor 20, and two stepper motors 20 are respectively through on two relative casing sides that are bolted to exhibition booth case 1 inside.
The course of work: under initial conditions, pneumatic system 6 is not worked, and the piston rod 24 of the common cylinder 37 of double-acting piston is in the state of not stretching out, and exhibition dish 3 is positioned at exhibition booth case 1, and two active plugboards 16 of active plugboard mechanism 2 are in closure state.Side door 38 through opening exhibition booth case 1 is put into showpiece.
After the exhibition booth worked on power, two stepper motors 20 were started working simultaneously in the AT89C52 Single-chip Controlling active plugboard mechanism 2, and stepper motor 20 drives screw rod 22 and rotates, and nut 23 is together retreated along guide rail 18 with plate 16 thereby screw rod 22 rotates the drive translation.Stepper motor 20 quits work when plate 16 retreats into the precalculated position.The principle that two plates 16 are retreated is identical.After two plates 16 of active plugboard mechanism 2 separate; Bi-bit bi-pass solenoid directional control valve 34 switching-overs of AT89C52 Single-chip Controlling pneumatic system 6; The gases at high pressure of source of the gas 28 inputs at first are connected to the air inlet of pressure-reducing valve 33 through parallelly connected gas circuit and filter 32; After gases at high pressure feed the rodless cavity of the common cylinder 37 of double-acting piston through pressure-reducing valve 33 and bi-bit bi-pass solenoid directional control valve 34 backs; Process flow speed control valve 36 is throttle grverning in the loop; The piston rod 24 that guarantees the common cylinder 37 of double-acting piston through the speed governing of flow speed control valve 36 slowly rises, and then the connection end cap 27, connection chassis 26, DC speed-reducing 10, pinion 11, gear wheel 12, the exhibition dishes 3 that promote above the piston rod 24 together rise, when piston rod 24 moves to the top of cylinder; Exhibition dish 3, rubber washer 13 and on showpiece stretch out the exhibition hole 9 on the exhibition booth case 1, this moment, showpiece was in the state of being showed.AT89C52 Single-chip Controlling bi-bit bi-pass solenoid directional control valve 34 is when another direction switching-over; When gases at high pressure finally are passed into the rod chamber of the common cylinder 37 of double-acting piston; Can realize returning fast of piston rod 24, drive showpiece and be withdrawn into rapidly in the exhibition booth case 1.Showpiece stretches out after the exhibition booth case 1; AT89C52 Single-chip Controlling DC speed-reducing 10 is started working; DC speed-reducing 10 is through being delivered on the drive link 4 torque and the rotating speed of gear drive with DC speed-reducing 10, thereby drive exhibition dish 3, rubber washer 13 and showpiece rotate.When the exhibition booth switches on work; Four vibrating sensors 15 can detect the vibration of different frequency more delicately; Showpiece blocks the infrared ray that photoelectricity sends near switch 14 under the safe condition; Nine electrodes of MC33794 electric-field sensor be arranged in uniformly rubber washer 13 on the exhibition dish 3 around, around showpiece, form a dynamic spatial detection zone when exhibition dish 3 rotates.If the exhibition booth receives stronger vibration, object illegally near showpiece; Perhaps the showpiece exhibition of leaving that is moved was suddenly coiled 3 o'clock; Bi-bit bi-pass solenoid directional control valve 34 switching-overs of AT89C52 Single-chip Controlling pneumatic system 6; Gases at high pressure feed from the rod chamber of the common cylinder 37 of double-acting piston; Piston rod 24 drives connection end cap 27, connection chassis 26, DC speed-reducing 10, pinion 11, gear wheel 12, drive link 4, exhibition dish 3 and showpiece and falls rapidly, and when piston rod 24 fell to the bottom of the common cylinder 37 of double-acting piston, exhibition dish 3, rubber washer 13 and showpiece moved to the inside of exhibition booth case 1 just.
When showpiece moves to the inside of exhibition booth case 1; Two stepper motors 20 of AT89C52 Single-chip Controlling are worked simultaneously; The output shaft of stepper motor 20 is done rapid circular movement by rightabout when opening active plugboard mechanism 2; Drive screw rod 22 with same rotational speed through shaft coupling 21, screw rod 22 quick rotation drive translation nut 23 rapid movements, advance fast thereby drive plate 16.When two stepper motors 20 turned over preset angle value, two active plugboards 16 were closed fully just, and AT89C52 Single-chip Controlling buzzer sends chimes of doom simultaneously.Improved the security performance of exhibition booth, played automatic protection showpiece.
