Description

Tunnel wall reflection train advertisement system using multiple control method {Display system for advertisement using reflected image}

In order to advertise on subway trains, various advertisements are placed on the inside of the train and passengers see them so that the advertisement contents can be delivered. In addition, the billboards are placed on the walls of the subway passages, and the advertisements are delivered by allowing passengers passing by or passengers inside the train to see through the window. Passengers on a moving train cannot grasp the fixed image as the train passes by. The way to find out is that if there is an image of the outside moving at the same speed as the train, it is like seeing a stationary image because it is moving at the same speed from the passenger's side. When viewed through the window, the effect is to view a still image. Conventional patent applications use advertising techniques in the subway using this relative principle.

Application No. 1997-041455 (application date: August 27, 1997) uses this principle to make the light panel on the outside of the train in the subway move at the same or similar speed as the train to view the stationary image Was used as an advertising technique. In addition, US Patent No. 5580140 (Applicant Burkhard Katz et al., Patent Title: Device for the presentation of images to the passenger of moving vehicle) applied this technique using the subway tunnel wall.

The technical problem to be devised is to display the advertisement contents on the wall of the dark tunnel outside the window when the train passes through the tunnel, and a plurality of projectors are installed in each vehicle of the train and managed centrally to control each train compartment. In the eyes of the passengers, the effect is that the still image is displayed on the tunnel wall. Through this, the advertisement contents of the wall of the tunnel can be seen and recognized through the window.

The present invention is to install a projector to enlarge the advertising image on the wall of the train and to reflect the image on the wall of the tunnel, and store a plurality of advertising images in one projector and project them sequentially, but directly manage the management It's about a system that lets you do that. If the projector is installed on the wall of the train and the image is projected on the wall of the tunnel, the projector moves like the train, so the image projected on the wall of the tunnel will move at the same speed. The effect is to see still images.

1 shows a projector 4 fixed to a wall 3 around a train 1 of a subway and a window 2 of a train. The image 5 mounted on the projector is enlarged by the light emitted from the projector and appears as an enlarged image 7 on the subway tunnel wall 6.

At this time, the location of the projector can be installed on the wall of the train that can display the image, and can be installed anywhere, such as the ceiling or the side wall of the train, which can install the projector that can enlarge the image even if it is not the side wall of the train.

The projector functions to display an image in the form of a camera film or printed on transparent vinyl at a magnification desired.

2 shows a structure in which the image enlarged by the projector is reflected on the wall. In order to reflect, the walls of subway tunnels can be directly used as reflectors, and the walls of subways can be painted separately or reflectors made of materials such as paper, cloth or vinyl can be installed. From the projector 13 installed around the window 12, a light 14 that enlarges the image comes out and the light is reproduced and reflected on the screen 17 installed on the tunnel wall 16 to reflect the glass window of the train. (12) The light (18) enters and is visible to the passengers 19 on the train. The train continues to proceed in one direction (20), even in this case it is shown to the passengers on the train as a still image.

The type of screen is fixed to the tunnel wall by fixing the vinyl material with the outer border like a signboard.

Another way is to paint the walls white and use them as screens.

In the above structure, in order for the passenger to see the image through the window, the light from the projector has an acute angle 15, which is an angle smaller than 90 degrees on average so that the light can enter the window.

Train passengers can see advertisements through the windows that reflect the image of the tunnel wall as the train passes through the tunnel.

3 shows the structure of the projector attached to the wall of the train. The bottom plate 23 of the projector is fixed to the wall 21 of the train as a bolt and a nut 22.

A light source 26 made of a halogen lamp or the like contained in the projector barrel 25 emits light 28 when the power supply is connected.

In this case, a reflection plate 27 may be installed to increase the efficiency of light.

Light from the light source enters the lens system 31 to enlarge the image. The incident light magnifies the image 33 by the lens 32 array.

The lens system for enlarging an image may use various image magnification lens systems used in conventional slide projectors, light illuminators, projection TVs, and the like.

The projector system as a whole is protected by an outer protective wall 24 due to the running characteristics of the train.

The image 34 magnified by the projector is projected onto the screen 35 of the subway tunnel wall.

4 shows a system for storing a plurality of images in a projector and sequentially controlling and projecting them.

The image 42 to be projected is printed on the film 41 and wound around the round shaft 43 in the form of a roll, and the images are sequentially displayed while rotating the roll by the motor 44. On the film, a barcode 51 for reading image information is drawn, and the light emitting unit 51 and the light receiving unit 52 serve as a bar coder reader for reading the barcode, so as to check which advertisement image is currently projected by reading the barcode. Do it. Barcode images can be read automatically as the roll of film rolls, combining how many times an ad is projected per hour and the projection time per shot. In addition, since a plurality of projectors are used, when the same advertisement image is not used for each projector, it is used as a means of determining which advertisement image is recorded in which projector.

The electronic controller 55 controls the motor drives 44 and 45 and the lamp 53 to be turned on and off and the sensor units 51 and 52.

Turn the motor in one direction sequentially and then turn it in the opposite direction as the opposite motor. At this time, instead of turning continuously, if one image comes to the front, stop the motor, project this image for a fixed time, and proceed to the next image.

It also plays a moving image like a movie by continuously rotating a series of commercial images, like a movie projector for a short time. The moving picture information is recorded in the barcode, and the starting point and time of the moving picture are recorded to reproduce the moving picture during this time.

An example of a recording system in which bar codes are recorded is as follows.

The barcode records the name of the current image and whether it is a clear image or a moving image, and the time to be displayed in the case of a clean image and the start time and end time in the case of a moving image.

Therefore, the display on this roll can reproduce both a purified image and a moving image.

To this end, if necessary, the electronic control unit reproduces the lamp with a storobo effect.

5 shows a structure of a central control device for controlling a plurality of projectors.

There are multiple vehicles connected to the train, and each vehicle has multiple windows, so if you add up the number of projectors around each window, several tens of projectors are mounted on the train. Therefore, there is a need for a system for centralized control and management by wire or wirelessly.

Each projection system 62 has an electronic control unit 65, a lamp unit 66, a film slider driving motor 67, and a sensor unit 68 for reading barcodes as described above. In order to control the plurality of projection systems 62, 63 and 64, the central control unit 61 controls it.

The central control unit 61 manages and controls the type, time and number of advertisement images read through the power supply and barcode, and whether the lamp and the slider motor managed by each electronic controller are controlled. Do In general, a central management system is indispensable because advertisements must be renewed or changed after a certain contract period.

The central control unit is commonly used as a computer system and controls this by utilizing an external device connection port of the computer system.

The central control unit also determines whether it is in a tunnel, a boarding station or on the ground, and signals the electronic control unit to control the lamp to turn on and off. That is, the lamp is turned on only in the tunnel and the lamp is turned off outside the tunnel. The central control unit has a separate discriminating sensor unit, which discriminates whether it is currently in a tunnel or a passenger boarding point. As an example, the light sensor is used to turn on the lamp by detecting the signal from the electronic controller in the dark part of the tunnel if the part is dark in the tunnel.

Alternatively, an ultrasonic signal oscillator is installed at the entrance and exit of the tunnel by using an ultrasonic sensor, and when the train enters or exits the tunnel, the ultrasonic sensor receives this signal and controls the lamp unit on / off.

Alternatively, an infrared signal oscillator is installed at the entrance and exit of the tunnel using an infrared sensor, and when the train enters or exits the tunnel, the infrared sensor receives this signal and controls the lamp unit on / off.

These sensors are installed only in the front and the rear part of the train, the sensor part of the front part detects when the train exits the tunnel, and the rear part detects when the train enters the tunnel, so that the central control unit 61 Allows you to control the electronic control unit.

The central control unit controls all electronic controls installed in the train from the train cockpit or other location, and can be operated manually by the crew managing the train or automatically by receiving signals from the sensors.

The effect of the present invention is to install a projector on the wall of the train of the subway and the image is projected on the wall of the tunnel so that the image moves as the train moves, so that the passengers actually riding the train has the same effect as seeing a still image It is to provide an efficient subway train advertisement management system by reproducing multiple images in one projector and managing multiple projectors from a central control unit.
