Abstract
The utility model discloses a subway synchronized projection device, and belongs to the technical field of subway advertisement devices. The subway synchronized projection device comprises a wide-angle projector, wherein a video image storage unit is arranged in the wide-angle projector, the wide-angle projector is installed on the upper edge of the inner side of a piece of carriage window glass, the wide-angle projector is connected with a trigger through a control cable, the trigger is installed on a train, and the projection device further comprises infrared laser sources for triggering the trigger to work. The infrared laser sources are arranged at the two ends of each platform or the entrance end and the exit end of each subway tunnel. According to the technical scheme, relative rest is achieved between passengers and video images, and therefore the playing effect of the video images is greatly improved. Due to the fact that each infrared laser source is composed of a plurality of parallel-connection lasers, normal work can be achieved only by one laser, and the trigger can normally start or close the wide-angle projector. Safety performance of the projection device is greatly improved, and meanwhile the subway synchronized projection device has the advantage of being low in cost.
Description
Technical field
The utility model belongs to the tube advertising equipment technical field, particularly relates to a kind of subway synchronized projection equipment.
Background technology
At present, along with social high speed development, subway has become one of important vehicles of people's go off daily, working, as everyone knows, because the subway major part is to travel underground, therefore, than traditional public transport or other ground traffic toolses, the subway internal environment is dimer, uninteresting; Therefore cause sense of depression to a certain degree to people; In order to overcome above-mentioned defect, people introduce subway by amusement equipment such as video, image, advertisements; At present, traditional subway video image mostly in the following way: one, on the subway tunnel wall, set up picture layer, then appreciate for the passenger by the mode of light-illuminating; Two, set up the LED screen on the subway tunnel wall, then by the LED screen, realize the broadcasting of video image; But practice finds, all there is defect to a certain degree in above-mentioned two kinds of modes: although to set up cost compare low such as the first kind of way single, from its cost of long-term consideration, sharply increase, also have the defect of replacing picture more complicated simultaneously; Although it is fairly simple that the second way is changed video image, because the LED screen is more expensive, lay cost compare high; Simultaneously, for above-mentioned two schemes, owing between video image and car body, having relative motion, the passenger of the interior of therefore running at high speed is difficult to see clearly the static video image in outside; Therefore, design a kind of subway synchronized projection equipment and seem particularly important.
Summary of the invention
Goal of the invention of the present utility model is to overcome the deficiencies in the prior art, proposes a kind of good visual effect, security performance is high, simple in structure, cost is low subway synchronized projection equipment.
The technical scheme that the utility model is taked for the technical matters existed in the solution known technology is:
A kind of subway synchronized projection equipment, comprise projector; Described projector is the wide-angle projector, be provided with the video image storage unit in described wide-angle projector, described wide-angle projector is installed on the coboundary of car windows glass inner side, described wide-angle projector is connected with the trigger on being installed on train by control cables, described projector equipment also comprises that, for triggering the infrared laser source of described flip-flop operation, described infrared laser source is arranged at the two ends of each platform or inlet end and the endpiece of every section subway tunnel.
As preferably, the utility model has also adopted following technical scheme:
Described infrared laser source is by 10-30 laser constitution parallel with one another.
Described wide-angle projector is installed on the centre position of car windows glass inner side coboundary.
Advantage and the good effect that the utlity model has are:
One, by adopting technique scheme, the utility model has been realized relative static between passenger and video image, so the travel speed of passenger's visual effect and train has nothing to do, and has greatly improved the result of broadcast of video image;
Two, the infrared laser source of selecting due to the utility model is by a plurality of laser constitutions parallel with one another, and therefore, in practical work process, as long as there is a laser instrument to work, trigger just can normally start or cut out the wide-angle projector; Therefore greatly improved security performance of the present utility model.
Three, all parts of selecting due to the utility model is conventional standard components and parts, therefore is convenient to assembly and connection, and cost is also lower simultaneously.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1, trigger; 2, control cables; 3, wide-angle projector; 4, infrared laser source; 5, subway tunnel wall.
Embodiment
For further understanding utility model content of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1, a kind of subway synchronized projection equipment, comprise trigger 1, control cables 2, a plurality of wide-angle projector 3 and infrared laser source 4; Wherein: between a plurality of wide-angle projector 3, be connected in parallel to each other; Be provided with the video image storage unit in wide-angle projector 3, wide-angle projector 3 is installed on the coboundary of car windows glass inner side, as preferred version, wide-angle projector 3 generally is installed on the centre position of car windows glass inner side coboundary, wide-angle projector 3 is connected with the trigger 1 on being installed on train by control cables 2, and infrared laser source 4 is arranged at the two ends of each platform or inlet end and the endpiece of every section subway tunnel; Infrared laser source 4 sends trigger pip to trigger 1, and trigger 1 completes the control work to wide-angle projector 3 after receiving above-mentioned trigger pip; In order to improve the security of this programme, infrared laser source 4 is by 10-30 laser constitution parallel with one another.In this specific embodiment, infrared laser source 4 is by 5*5 25 laser constitutions parallel with one another altogether.
Using method of the present utility model and the course of work are: the coboundary that at first wide-angle projector 3 is installed on to the car windows glass inner side, video image content is stored in the video image storage unit of wide-angle projector 3, then set up into projector equipment according to above-mentioned annexation, infrared laser source 4 is arranged to inlet end and the endpiece (can be also the two ends of each platform) of every section subway tunnel, when train driving advances subway tunnel, the infrared laser source 4 of subway tunnel inlet end sends enabled instruction to trigger 1, trigger 1 is assigned open command by control cables 2 to all wide-angle projector 3 after receiving instruction, now, wide-angle projector 3 see through glass for vehicle window by projecting video image on the wall of subway tunnel, in order to improve the quality of projected picture, generally the wall plastering of subway tunnel can be become to unified tone, such as white or canescence, when train driving goes out subway tunnel, the infrared laser source 4 of subway tunnel endpiece sends out code to trigger 1, trigger 1 is assigned out code by control cables 2 to all wide-angle projector 3 after receiving instruction, now, wide-angle projector 3 stops the displaying video image.
Above a kind of embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
