Description

Laser traffic signal lamp

Technical Field

The invention relates to a system arrangement for a laser traffic signal lamp, comprising an information transmitter on a traffic route and an optical information reproduction device. The controller has an information receiver, the controller being connected to, preferably integrated into, the information transmitter.

The invention relates to a system arrangement for laser traffic lights for traffic information, in which arrangement an information transmitter is located on a traffic route, in particular on a road, and the traffic information from the information transmitter is displayed by means of an optical information reproduction device.

Background

It is known that bridge displays for existing highways often have traffic control systems which display speed limits suitable for traffic or weather conditions. Methods for optically reproducing traffic information are also known, in which, for example, traffic information is received by an information system of a motor vehicle and is displayed, for example, on a display of the device.

The previous systems and methods described generally use widely available information systems and are therefore completely unsuitable for the local environment of the relevant traffic routes.

Disclosure of Invention

The object of the invention, which is to provide a device and a method for reproducing traffic information with a high degree of personalization, is achieved by a system device for optically reproducing traffic information. The system device has at least one information transmitter located on a traffic route and at least one optical information reproduction device, wherein a controller has an information receiver, wherein the controller is connected to the information transmitter, the controller is preferably integrated into the transmitter, and the information transmitter has a transmission and/or projection unit which projects traffic information received by the information receiver and to be reproduced onto the reproduction device or transmits the traffic information to the reproduction device, wherein the reproduction device is spatially separated from the information transmitter.

The system arrangement is provided with a controller with an information receiver, which is connected to an information transmitter located on a traffic route, which controller can even be integrated into the information transmitter, which information transmitter can in particular be a traffic route luminaire, commonly referred to as street lamp, wherein the term traffic route includes, besides roads, intersections, bicycle lanes and other transport routes. Accordingly, a traffic route luminaire should be understood to be not only a street lamp, but also other lighting uses in relation to a traffic route. The information transmission type, not the projection type, may be implemented as follows: the information is transmitted from the information transmitter located on the traffic route to the transport device or to a display in the transport device or to a display device of the road user, in particular a mobile display device. The traffic information to be transmitted is then displayed, for example, on the navigation device of the vehicle or in another display area in the field of view of the driver of the vehicle. For example, in contrast to conventional systems in which traffic notifications are transmitted via radio to the navigation system of a vehicle, the information reproduction apparatus proposed herein receives only information from spatially adjacent information transmitters. Thus, such information is considered to be more relevant, and in the case where the information is spread over a large number of areas as in the prior art, a reduction in attention and a dulling effect of the vehicle driver are caused. For the transmission of information according to the invention in a reproduction device in a transport device or on a display device of a road user, it is preferably possible here to use components which are suitable for short-range communication and are therefore even suitable. However, it is naturally also possible to use conventional broadcast transmission in the vehicle, using standard broadcast transmission. The information receiver of the system apparatus according to the present invention can obtain its data through the network. Multiple sets of information transmitters may also be incorporated into a large network. In particular, the program interface of the traffic control computer is advantageously arranged in connection with the controller. However, the system device can also have its own sensors, for example for detecting the degree of busyness of the air humidity, temperature and/or traffic route. Thus, for example, if a road user, such as a vehicle, is actually approaching the information transmitter, only the information to be reproduced will be transmitted or projected. The sensor or one of the sensors may also be designed as a human detector. In this way, it is possible, for example, to detect whether a person intends to cross the road, for example at the zebra crossing, as a result of which, for example, a warning sign is added to a vehicle which is also approaching.

In the system arrangement of the invention, a plurality of information transmitter connections can also be connected to one another, so that data forwarding and/or data exchange can take place between the controllers of the information transmitters. This enables communication between controllers and or between a controller and e.g. a central unit (e.g. a server controlling an associated luminaire network). For example, as the vehicle moves along the plurality of information transmitters, the imaged traffic information symbol is thus reproduced a plurality of times. A controller may also be shared by a plurality of closely spaced information transmitters when the information transmitters are connected in a conventional manner, such as by a cable.

Detailed Description

As shown in fig. 1, a lamp post 1, a lamp holder 2, and a traffic route illuminator 3.

As shown in fig. 2, a lamp post 1, a lamp bracket 2, a traffic route illuminator 3, a laser traffic signal lamp 4, a laser traffic signal lamp, and a road structure 5.

As shown in fig. 3, a lamp post 1, a lamp holder 2, a traffic route illuminator 3, a laser traffic signal lamp 4, a laser traffic signal lamp and road structure 5, a car 6, a car absorption annunciator 7, the laser traffic signal lamp 4 emitting the annunciator 7 when the vehicle approaches, the car 6 absorbing the signal projecting traffic information 7 to be displayed on one or more displays in the vehicle, the information transmitter having a transmitting and or projecting unit which transmits or projects the traffic information received by the information receiver and to be reproduced to or onto the information reproducing device under the control of the controller, wherein, also according to the present invention, the information reproducing device is spatially separated from the information transmitter. Thus, the present invention is not concerned only with directly driven laser light indicators, as opposed to the prior art. The transmission of information from the information transmitter to the information reproduction apparatus can thus be realized in particular by means of light waves, in contrast to the prior art, in which the reproduction apparatus is not part of the information transmitter. Even conventional traffic route luminaires are therefore able to project traffic information signals directly onto the traffic route, for example by means of an optical module. This method is particularly useful at night or in tunnels. In order to also enable projection in case of higher brightness, for example during the day or in general when traffic routes are illuminated, a spray generator may be used which is coupled to the information emitter and outputs a spray or artificial fog at the location where the projection of traffic information is to be performed. The mist output in this case forms a temporary information reproducing device. The spray generator may for example be integrated into the pole of the information transmitter or be arranged spatially separate from but adjacent to said information transmitter, which surface area may be designed to enhance luminescence and or reflection, for example by means of suitable admixtures in the road surface coating, in order to improve visibility in the case that traffic information is projected onto the surface area of the traffic route. The surface area of the traffic route formation reproduction device may also be configured to be calibrated to a particular light wavelength. Thus, for example, the surface area of a traffic route can already contain traffic information symbols in a figurative manner, wherein the symbols become visible only when irradiated with a predetermined light wavelength. The radiation or projection of the projection unit can then have no shape when the surface area of the traffic route is projected, because the desired shape becomes visible only with the aid of a specific configuration of the surface area of the traffic route. In this way, it is also possible to provide a plurality of traffic information symbols in the surface region of the traffic route by means of different dopants or coatings which react to different wavelengths of light. For this purpose, the information transmitter, in particular the traffic route luminaire, should have a module for outputting different light wavelengths and or spectra under the control of the controller. The information or light output can also be realized in a pulsed manner, as a result of which the traffic information symbol flashes.
