Specific embodiment
Below in conjunction with drawings and examples, the present invention will be described in further detail.It should be appreciated that described herein
Specific examples are only used to explain the present invention, is not intended to limit the present invention.
The present invention discloses a kind of subway optoelectronic induction advertisement play systems, as an inventive point of the invention, including
Subway train 1, induction of signal equipment 2, central control host 3, server 4, optical projection system 5 and energization glass screen 6；The letter
Number it is connected between sensing apparatus 2 and central control host 3 by signal, the central control host 3 controls service simultaneously respectively
Device 4 and optical projection system 5；And the central control host 3 connects energization glass screen 6 by signal, realizes control energization glass
The vitreousness of screen 6.In this embodiment of the invention, the vitreousness includes transparent or opaque.
Specifically, the induction of signal equipment 2 senses that train arrives as shown in Figure 1: when operation, it is sent to and carrys out signal
To central control host 3, the central control host 3 sends a signal to server 4 and suspends film or video playing, meanwhile, hair
The number of delivering letters closes shutter barrier gate to optical projection system 5, meanwhile, the equipment power supply where energization glass screen 6 is sent a signal to, is led to
Electricity, so that 6 bleach of energization glass screen.
As shown in Figure 2: induction of signal equipment 2 senses that train leaves, and transmission leaves signal to central control host 3, institute
It states central control host 3 and sends a signal to the broadcasting that server 4 starts film or video, meanwhile, send a signal to optical projection system 5
Shutter barrier gate is opened, meanwhile, send a signal to the equipment power supply where energization glass screen 6, power-off, so that energization glass screen
6 become in opaque.In the present invention, energization glass screen 6 is applied on subway station train so that train driving also have it is hidden
Private and confidentiality, for people's daily life protection also more fully, in addition, pass through the strict control of central control host 3,
This system is effectively served in subway train, and guarantees that train normally travel is unaffected.
Based on foregoing description, optical projection system 5 of the invention includes laser-projector, the projecting direction court of the laser-projector
To the energization glass screen 6, the energization glass screen 6 is layer structure, including interior transparent glass substrate, outer glass substrate
And it is fitted in the liquid crystal film between interior transparent glass substrate and outer glass substrate, the outer glass substrate is opposite with liquid crystal film
Surface is adhesive with antiultraviolet film.User controls the transparent and opaque state of glass whether passing through the on-off of control electric current.
Glass itself not only with all safety glasses characteristic, while but also with control glass transparent whether privacy protection function,
Due to the characteristic of liquid crystal film interlayer, energization glass is also used as projection screen use, substitutes common curtain, presents on glass
High definition picture image.
As another inventive point of the invention, in this embodiment of the invention, pacify in the energization glass screen 6
Equipped with energization glass screen stability maintenance mechanism.Specifically, as shown in Figure 3: the stability maintenance mechanism includes lower stabilization device 71 and upper steady dress
72 are set, the upper stabilization device 72 is mounted on 6 top of energization glass screen, and the lower stabilization device 71 is mounted on energization glass screen 6
Lower section, the upper stabilization device 72 and lower stabilization device 71 are in " product " shape distributing installation.Lower stabilization device 71 includes that two structures are identical

Certain fixed range is kept between " scholar " font stability maintenance block 710.In this embodiment of the invention, two " scholar " words are set
Type stability maintenance block 710 maintains a certain distance, and moves synchronously, and when can be to avoid stability maintenance block relative motion, energization glass be generated
Incorgruous magnetic field, hinders the movement of energization glass screen 6, so that unnecessary danger is generated, meanwhile, two " scholar " font stability maintenance blocks
Certain fixed range is kept between 710, can generate during exercise serious inclination or imbalance to avoid energization glass.This
Outside, the upper stabilization device 72 includes horizontal stability maintenance block 720 and perpendicular stability maintenance item 721, and the horizontal stability maintenance block 720 passes through upper stability maintenance track
722 movements, the perpendicular stability maintenance item 721 are vertically mounted on horizontal stability maintenance block 720.The horizontal stability maintenance block 720 passes through upper stability maintenance track
722 movements guarantee to form " product " shape with lower stabilization device 71, stable structure, and the perpendicular stability maintenance item installed on horizontal stability maintenance block 720
721 are used to fix horizontal stability maintenance block 720, control horizontal 720 direction of motion of stability maintenance block and movement speed.
As another inventive point of the invention, in this embodiment of the invention, as shown in Figure 4: the upper stability maintenance
Track 722 includes the fixing seat 7220 at both ends and the track ontology 7221 of centre；The track ontology 7221 includes four rails
Road unit, seamless interfacing between each track element, each track element include (left and right) siding track 72210, track
Tooth 72211 and stability maintenance plate 72212；The track tooth 72211 is separately positioned on above left and right siding track 72210 and forms gear track；
The stability maintenance plate 72212 is mounted between left and right siding track 72210, and vertical left, right side rail 72210.In the present invention, if
Set stability maintenance plate 72212 effect be upper stability maintenance track 722 can in significantly more efficient realization stabilization device 72 movement, for example, working as
It, can will be under the rotation to siding track 72210 of track tooth 72211 of the top of left and right siding track 72210 when Caton occurs for energization glass screen 6
Side re-starts movement by stability maintenance plate 72212, secondary motion guarantee is realized, in addition, as it is further preferred that in this hair
In bright, stability maintenance plate 72212 can not have to be vertically set between left and right siding track 72210, can also tilt certain angle, example
Such as, 15 degree, 20 degree, 25 degree, 30 degree etc., the setting of different angle, can in various degree raising energization glass movement velocity,
Tilt angle is bigger, and stability maintenance plate 72212 is more smooth, and the movement velocity of energization glass screen 6 is most fast.
As it is further preferred that in the present invention, as shown in Figure 5: the stability maintenance plate 72212 retains a straight panel 80 and one
Arc panel 81, the arc panel 81 are integrally formed with straight panel 80；As shown in figure 5, the arc panel 81 is fixed on left and right siding track
The side of 72210 any siding track, the addition of arc panel 81 help to be vertically set on left and right siding track when stability maintenance plate 72212
When between 72210, it can also accelerate the movement of energization glass screen 6, the arcwall face of arc panel 81 is more advantageous to energization glass screen 6
It is run along upper stability maintenance track 722.
