Utility Model Description

IPC G09F 19/18

Atraumatic means of traffic management

Technical field

The utility model relates to road maintenance equipment, in particular to technical means of organizing traffic (according to GOST 52289-2004 "Technical means of organizing traffic. Rules for the use of road signs, markings, traffic lights, road fences and guiding devices" technical means of organizing traffic - traffic signs, markings, traffic lights, road fences and guiding devices) and can be used to inform road users about conditions and modes traffic, as well as situations restricting the movement of vehicles.

State of the art

The closest technical solution (prototype) is the Softstop system (URL: http: //www.laservision.com.au/page.asp? Lid = 1 & sec = Projects & subsec = Permanent + Attractions & subsubsec = Softstop, accessed 04.09.14). The image of the desired traffic sign is projected by means of a laser projector onto the screen. The laser projector consists of the light source (s) - the laser (s) and the imager, which builds the image on the screen by deflecting the laser beam. The laser forms on the screen a relatively small light spot of a certain color, which moves along the same path as the laser beam. Moreover, a person perceives an image not as a multitude of light spots of different colors, but as a whole image. The screen consists of means for holding the projection element and the projection element. A water curtain is used as a projection element, and a special nozzle system is used as a means of holding the projection element. Water through a system of nozzles forming narrowly directed jets falls vertically downward and enters a special water tank. Further, in a closed circuit, water again enters the nozzle system. To maintain the system, a pump is used that moves water to ensure the operability of the device.

The disadvantage of the prototype is the complexity of the design. This is due to the fact that a water curtain is used as a screen, therefore, a special water circulation system is needed. In addition, the performance of the device deteriorates at negative ambient temperatures, since the water used in the device goes into a solid state (ice) at a temperature of approximately 0 ° (the temperature of the transition of water from a liquid to a solid state depends on atmospheric pressure). Another disadvantage of the system is the lack of mobility of the device, since the water tank must be mounted buried in the ground (roadbed) so that the water tank does not interfere with the movement of vehicles.

The technical result of the proposed utility model is to simplify the design of the means of organizing traffic, ensuring the operability of the device at low ambient temperatures, as well as increasing the mobility of the device.

This goal is achieved due to the fact that the atraumatic means of organizing traffic contains a support element, a screen with means for holding the projection element and the projection element with a scattering surface, a laser projector containing a laser and an imager, vertical positioning means, means for holding the laser projector at a distance from screen, and the means of holding the projection element is fixed to the supporting element, the projection element is fixed by one edge to the medium to hold the projection element, and vertical positioning means are attached to the other edge, the laser projector is fixed to the means of holding the laser projector away from the screen, the means of holding the laser projector away from the screen is fixed to the screen holding means, the laser projector is located relative to the screen the scattering surface, while the projection element is made in the form of a canvas, and the vertical positioning means is made in the form of a weighting material or fasteners to ozhnomu web.

Brief Description of the Drawings

The utility model is illustrated by drawings (FIGS. 1-4), where in FIG. 1 shows a front view of the device according to the first embodiment, in FIG. 2 shows a side view of the device according to the first embodiment, in FIG. 3 shows a general view of the device according to the first embodiment; FIG. 4 shows a general view of the device made according to the second embodiment.

Utility Model Disclosure

In the figures: means for holding the projection element 1, a laser projector 2, the projected image 3, the scattering surface 4, the screen 5, the projection element 6, the means of vertical positioning 7, the supporting element 8, the means of holding the laser projector away from the screen 9, laser 10 , imaging device 11, laser beam 12, vehicle 13, roadbed 14.

The main elements of the device according to the first embodiment are the screen 5 and the laser projector 2. The main element of the device according to the second embodiment is the laser projector 2.

The screen 5 is designed to display on it the projected image 3 (hereinafter referred to as the image) created by the laser projector 2. Screen 5 consists of two main parts: the projection element 6 and the holding means of the projection element 1, on which the projection element 6 is fixed.

The projection element 6 is designed to project an image onto it. At least one of the surfaces of the projection element 6 must be scattering, i.e. reflect the light incident on it almost uniformly in all directions within an angle of 180 °. In addition, the material of the projection element 6 must be atraumatic, i.e. its rigidity should be minimal. This is necessary so that in a collision of a vehicle 13 with a means of organizing traffic, damage to the vehicle 13 and means of organizing traffic would be minimal. In particular, the projection element 6 is made in the form of a canvas - a large wide cut of material fixed at the ends or hanging freely (URL: http: //dic.academic.ru/dic.nsf/es/45144/%D0%BF%D0% BE% D0% BB% D0% BE% D1% 82% D0% BD% D0% BE, accessed 09.09.2014). In this case, the canvas may be coated with a special composition.

One edge of the canvas is fixed to the means of holding the projection element 1. The material of the canvas (for example, fabric or a special multilayer material on a fabric basis) is subject to deformation, therefore, the means of holding the projection element 1 should give the canvas the necessary configuration. In particular, the means of holding the projection element 1 is an elongated object, two sizes of which (height and width) are small compared to the third size (length), and can, for example, be in the form of a single beam or a spatial rod system ( rod system - a supporting structure consisting of straight or curved rods connected to each other in nodes, URL: http://dic.academic.ru/dic.nsf/bse/136043/ Rod, access date: 09/23/27). The means of holding the projection element 1 must be located above the roadway 14, so it can be mounted on a vertical support element 8, located, for example, on the side of the road (post support element of the road sign, post support element of the lighting device, etc.) or horizontal support element (not shown in the figures) located above the road (crossbar support element of a road sign, structural element of an overpass, etc.).

Orientation of the web in space and preventing deformation of the web under the influence of, for example, wind or air currents from passing vehicles 13 is provided by the vertical positioning means 7. As the vertical positioning means 7, for example, a load attached to the edge of the projection element 6, opposite the one for which the projection element 6 is fixed to the means of holding the projection element 1.

A laser projector 2 is attached to the screen 5. Laser projector 2 is a device designed to create an image 3 by projecting it onto a surface, in particular onto a screen 5 according to the first embodiment of the device or onto the roadway 14 according to the second embodiment of the device. A laser 10 (or three lasers for displaying a multi-color image 3) is used as a light source in the laser projector 2. In addition, an imaging element 11 is an important element of the laser projector 2.

Laser 10 is a device that is a source of coherent monochromatic radiation (in this case, the optical range). Typically, the laser 10 consists of three main elements: an energy source, a working fluid of the laser and an optical resonator. The type of energy source used depends on the working fluid used (liquids, gases, some solids, etc. can be used as the working fluid). On opposite sides of the working fluid (working medium) of the laser are optical resonator mirrors, for example, a pair of parallel mirrors, one of which partially transmits light. In this case, part of the radiation of the working fluid passes through a translucent mirror, and the other part of the radiation is reflected and again sent to the working fluid. The amplified radiation is reflected from an opaque mirror, again sent to the working fluid, after which part of the working fluid's radiation again passes through the translucent mirror, and the other radiation is reflected etc.

Imaging device 11 is a device for constructing an image 3 by deflecting the laser beam 12. The imaging device 11 can be performed on the basis of a mechanical scanning system or on the basis of an acousto-optical modulator. As a mechanical scanning system, for example, a system of mirrors with the ability to scan the image 3 horizontally and vertically, i.e. consisting of at least two mirrors. The imaging device can be performed as an imaging device for road signs (according to the first embodiment) or as an imaging device for road markings (according to the second embodiment).

In addition, the imager contains information about the required road sign (according to the first embodiment) or about the required road marking element (according to the second embodiment). Based on this information, the required intensity of the laser beams, the angle of deviation of the laser beam, etc., are determined, which allows you to form the image of the sign on the projection element in a human-accessible form.

In one embodiment of the device, a laser projector is attached to the screen. The laser projector 2 is attached to the screen 5 by means of holding the laser projector away from the screen 9. In particular, the means of holding the laser projector away from the screen 9 can be made in the form of a bracket (bracket is a cantilever supporting part or design used for mounting on the vertical plane of the protruding or horizontally extended parts of the structures, URL: https://ru.wikipedia.org/wiki/Kronshteyn, circulation date: 09/04/2014). The means for holding the laser projector at a distance from the screen 9 to the screen 5 is mounted so that the image 3 can be projected onto the scattering surface 4 of the projection element 6 using the laser projector 2 mounted on the means for holding the laser projector at a distance from the screen 9.

According to another embodiment of the device, the laser projector is mounted on a vertical (or horizontal) support element. The laser projector is attached to the vertical (or horizontal) support element by means of holding the laser projector away from the screen 9.

Utility Model Implementation

The utility model is implemented as follows. The place of installation of the atraumatic means of organizing traffic is determined (the place of installation of means of organizing traffic is determined in accordance with GOST R 52289-2004 "Technical means of organizing traffic. Rules for the use of road signs, markings, traffic lights, road fences and guiding devices").

According to one embodiment of the device, the holding means of the projection element 1 is mounted on a vertical (or horizontal) support element. On the means of holding the projection element 1, the projection element 6 is fixed. Next, the vertical positioning means 7 is installed (for example, a special weight is fixed to the edge of the projection element 6 opposite to which the projection element 6 is fixed on the means of holding the projection element 1).

Next, a means for holding the laser projector at a distance from the screen 9 is fixed to the means for holding the projection element 1. At the end of the means for holding the laser projector at a distance from the screen 9, opposite to which the means for holding the laser projector at a distance from the screen 9 are fixed to the means for holding the projection element 1, install the laser projector 2.

According to another embodiment of the device, the means for holding the laser projector at a distance from the screen 9 is fixed to the supporting element (vertical or horizontal). At the end of the means for holding the laser projector at a distance from the screen 9, the opposite of that for which the means for holding the laser projector at a distance from the screen 9 is mounted on a vertical (or horizontal) support element, a laser projector 2 is installed.

A device made according to one embodiment can be used to display road signs, and a device made according to another embodiment can be used to display road markings.

After turning on the device, the desired image 3 (road sign or road marking element) is formed as follows. Each laser 10 emits light of a strictly defined wavelength. By mixing three different in intensity laser beams 12 (red, green and blue), white or any other desired color can be obtained. Therefore, the three laser beams 12 are modulated in amplitude using special electro-optical modulators (not shown in FIG.). Then these three laser beams 12 are combined into one laser beam 12 of a certain color, for example, using a system of translucent mirrors. This laser beam 12 is sent to the imager 11, which deflects the laser beam 12 horizontally and vertically (the image is scanned as in CRT-based televisions - in rows).

In the case of the imaging device 11 based on a mechanical scanning system, the image 3 is scanned, for example, using a pair of swinging mirrors, one mirror deflecting the laser beam 12 horizontally and the other vertically. And in the case of the imaging device 11 based on the acousto-optical modulator, the scan is based on light diffraction by a traveling ultrasonic wave in an optically transparent material. A traveling ultrasonic wave is created by a piezoelectric transducer connected, for example, to a glass plate. Due to the appearance of compression and tension sections arising in the material and differing in the refractive index, a diffraction grating is formed in the medium. The laser beam 12, diffracting on a grating, forms several output beams (diffraction orders), spaced in space at equal angles relative to each other. Of all the output rays, the first maximum is distinguished and all the others are blocked. The type of imaging device 11 is selected based on the requirements for image quality 3 and the estimated cost of the device as a whole (an imaging device based on an acousto-optic modulator has the ability to deflect a laser beam at a higher speed, but is not suitable for working with high-power lasers, an image former based on a mechanical scanning system, it can work with lasers of any power that can withstand mirrors, low cost, but at the same time has faster sweep speed due to the use of mechanical parts).

Thus, in the first embodiment of the device, the laser 10 forms a relatively small light spot of a certain color on the scattering surface 4 from the side of the approaching vehicle 13.

In another embodiment, the laser 10 forms a relatively small light spot of a certain color on the surface of the roadway 14.

The imager 11 deflects the laser beam 12 horizontally and vertically at high speed (respectively, when the laser beam 12 is deflected, the light spot on the scattering surface 4 (or on the surface of the roadway 14) moves along the same path, changing its color).

Due to the high speed of deflection of the laser beam 12 and the inertia of human vision (inertia of vision is a physiological phenomenon, which consists in the lag of the appearance and disappearance of visual sensation from exposure to a light stimulus; it is manifested by the presence of a latent period, the appearance of consecutive images, the fusion of light flickers, URL: http://dic.academic.ru/dic.nsf/medic2/18852, accessed: 09/08/2014), a person perceives Image 3 not as a multitude of light spots of different colors, but as a whole image.

In addition, due to a specially made projection element 6, having a scattering surface 4, reflecting the incident light almost uniformly in all directions within an angle of 180 °, the device has a large viewing angle (an angle at which you can observe the image without loss of quality) . If necessary, the device can additionally use a reflector (for example, a mirror, not shown in the figures), providing a change in the direction of propagation of the rays in the event that there is a need for the location of the imaging device 11 in such a position that the direct passage of rays from it to the scattering surface 4 is impossible or not optimal.

Thus, with a relatively simple design, an atraumatic means of organizing traffic provides the ability to inform drivers of vehicles 13 about traffic conditions and modes, about repair work of the roadway 14 (or any other situations that restrict traffic). Moreover, due to the location of the road sign in the visibility range of the driver of the vehicle 13, the possibility that the driver does not notice the warning sign is minimal. In addition, the atraumatic means of organizing traffic is made in such a way that, in the event of an emergency, there are no hard elements in the way of the vehicle 13 that could damage the vehicle 13 itself, harm the driver of the vehicle 13, pedestrians or, for example, workers repairing the roadway 14.
