Description

The utility model relates to the technique of road operation, in particular to the technical means of organizing traffic.

Saving electricity is an acute problem in any country in the world, while it is necessary to improve road safety, taking into account modern technologies.

From the prior art, a scheme of a pedestrian crossing is known, which contains a transition zone limited by four or more columns, each of which has several generators of visible laser beams operating in the same direction, but in different planes and at different angles, regulated by a control system that overlaps traffic flow of pedestrians or vehicles, and contains motion sensors that provide timely switching to a mode that prohibits movement (RU 176588 U1, pub. 01/23/2018 G08G 1/00).

The disadvantage of this device is the use of a laser light source, since the laser beam entering the eyes can lead to loss of vision.

A well-known design of an unregulated pedestrian crossing, which is a transition limited by four columns, each of which has a built-in generator of a visible laser beam, controlled by a control system that blocks the movement of pedestrians or cars in the transition zone, and a flat red laser light beam reflected by a cylindrical reflector illuminates the roadway on both sides along the pedestrian zebra (RU 177256 U1, published on February 14, 2018 G08G 1/09).

The disadvantages of the known solutions are their inapplicability for controlled pedestrian crossings, as well as the inability to control the illumination of vehicle traffic areas and the transition zone, which reduces the information purpose of the transition, especially at night, and, accordingly, its safe use.

A device for illuminating road markings is known, which includes at least two light sources placed in a closed housing and equipped with light flux formers for illuminating road marking elements, a light sensor, a power supply unit and a controller, the first, second and third inputs of which are designed to receive signals traffic light, while the shapes of the contours of the light-transmitting surfaces of the shapers of the light flux repeat the shapes of the corresponding contours of the road marking elements, the controller outputs are connected to the corresponding first inputs of the light sources, the second inputs of which are connected to the corresponding outputs of the power supply unit, the input of which is connected to the output of the light sensor (RU 92869 U1 , published 04/10/2010 E01F 9/06).

The closest analogue of the claimed utility model is a pedestrian crossing, including a lighting pole with a gobo projector with an information carrier located on it. The gobo projector is configured to generate light projections parallel to the axis of the carriageway in the region of the transition zone and perpendicular to the axis of the carriageway with the possibility of signaling vehicles. The gobo projector is connected to a control controller configured to control the projector's operation mode in terms of backlight control (RU 205143 U1, published 06/28/2021, G08G 1/005).

The disadvantage of these devices is high power consumption and equipment wear due to the constant operation of the equipment.

The technical problem to be solved is to eliminate the shortcomings of existing analogues by improving the design.

The technical result of the claimed utility model is the creation of a device for organizing a pedestrian crossing with the projection of road markings on the roadway, which is triggered at the moment an object appears at the pedestrian crossing, which saves electricity.

The claimed technical result is achieved by the fact that the device for organizing a pedestrian crossing contains a gobo projector with the ability to generate light projections parallel to the axis of the roadway in the transition area and perpendicular to the axis of the roadway with the possibility of signaling vehicles and additionally including a motion sensor configured to control operating mode of the gobo projector.

In an embodiment, the gobo projector can be connected to a traffic light control cabinet to synchronize the activation of the projection zebra at the moment the red traffic light is activated.

The utility model is illustrated by a graphical representation, where figure 1 shows a diagram of the installation of a projection complex with one projector, figure 2 shows a diagram of the installation of a projection complex with two projectors.

The device for organizing a pedestrian crossing (Fig. 1) includes a gobo projector 1 (a projection device), a motion sensor 2, a support 3. The gobo projector 1 includes an information carrier located inside with interchangeable lenses with the ability to generate light projections parallel to the axis of the roadway in the area of the transition zone and perpendicular to the axis of the carriageway with the possibility of signaling vehicles.

The claimed device for organizing a pedestrian crossing works as follows. A gobo projector 1 is installed on a vertical or L-shaped support 3 using a special mount. Gobo projector 1 is connected via a wired or wireless connection to a motion sensor 2. An information carrier is installed inside the gobo projector 1 for the projection of a pedestrian crossing in the form of a zebra ' or 'irregularity'. The gobo projector can be multi-slide and project road markings in the form of a zebra with additional information signs. Motion sensor 2 detects an object that has appeared in front of a pedestrian crossing and closes the electrical circuit to turn on projector 1. In the case when motion sensor 2 is connected to projector 1 via a wireless connection, the projector's power cable is connected to a transceiver (not shown conventionally in the drawing) that receives a signal about the short circuit or open circuit of the projector. If one projector is not enough to project the roadway, two or more gobo projectors can be mounted on a pole. Gobo projectors can be installed on different sides of the road. The motion sensor can be installed on both sides of the road to detect a pedestrian on one and the other side of the road.

The gobo projector can additionally be connected to a traffic light switch cabinet to synchronize the activation of the projection zebra at the moment the red traffic light is triggered, which will save energy and increase safety when a pedestrian crosses the roadway.

The claimed device fully realizes its purpose, namely the inclusion of projection lighting at the time the object is at the pedestrian crossing, which saves energy and ensures safety.
