Description

Technical field

The invention relates to the field of traffic safety.

State of the art

An invention is known (patent RU2539270, IPC G08G 1/096, Published: 01/20/2015 Bull. No. 2), which implements a method for interactive security at a pedestrian crossing, which consists in the fact that at a given height above the pedestrian crossing and in the road areas of the entrance of vehicles video cameras and light emitters are installed that form light images on the roadway and/or footpath; video signals to the hardware-software complex for processing and analyzing the situation, predicting events, the hardware-software complex, according to a given program, gives an audio signal and / or a command to light emitters.

The disadvantage of this method is the complexity of the design, the high cost of equipment, installation, adjustment and maintenance during operation.

An invention is known (patent RU2506368, IPC E01F 9/00, Published: February 10, 2014, Bull. No. 4), which implements a method for alerting drivers about the presence of a pedestrian at a pedestrian crossing, including lighting a pedestrian crossing when a sensor for the presence of a pedestrian at a pedestrian crossing is triggered. Illumination of the pedestrian crossing is carried out by visible light, regardless of the time of day, using an LED spotlight.

The disadvantage of the known method is the presence of a crossbar fixed to the support, located in the zone of the pedestrian crossing above the traffic lanes of vehicles, which limits the height of the carriageway.

A pedestrian crossing is known (patent RU156964, IPC G08G 1/00, Published: 11/20/2015 Bull. No. 32), limited by four columns containing several generators of laser beams acting in the same direction, but in different planes and at different angles.

A disadvantage of the known traffic control system at a pedestrian crossing is the difficulty for the driver to view moving objects that are in relation to the driver behind numerous visible inclined beams, as well as the lack of a warning system for drivers (failure to provide the driver with information) about the presence of a pedestrian at a pedestrian crossing or approaching him.

A known system for warning road users about the presence of pedestrians at or near a pedestrian crossing (patent RU2658210, IPC G08G 1/00, Published: 06/19/2018 Bull. No. 17), limited to four columns, and having a similar power system, sensors for detecting the presence of objects , visible laser beam generators and prism laser devices (prototype).

A disadvantage of the known warning system for road users is the low level of pedestrian safety due to the lack of timely information about the pedestrian's intentions to enter and start crossing the carriageway at the pedestrian crossing.

Disclosure of invention

The technical result is to increase the safety of pedestrians at an unregulated crossing by timely provision of information to the driver about the presence of waiting pedestrians.

The technical result is achieved in a system for warning road users at an unregulated pedestrian crossing, including a power supply system that is powered by a public electrical network or can be autonomous, battery-operated, an unregulated pedestrian crossing, which is limited by four columns, each of which has built-in presence detection sensors objects for passing through a pedestrian crossing and generators of a red laser visible beam with built-in red prism laser devices operating in a horizontal direction perpendicular to the carriageway from one column to another, located on different sides of the carriageway, and sensors for detecting the presence of objects for passing along pedestrian crossing are installed in additional columns, creating a pedestrian safety platform next to the carriageway of an unregulated pedestrian crossing, on columns along the perimeter of the safety platform generators of a yellow visible laser beam with built-in yellow prism laser devices were installed, with the ability to turn on generators of red and yellow visible laser beams, as well as red and yellow prism laser devices by a signal transmitted from sensors for detecting the presence of objects on the security site.

The distinguishing features are:

sensors for detecting the presence of objects for passing through a pedestrian crossing are installed in additional columns that create a pedestrian safety area next to the carriageway of an unregulated pedestrian crossing, such a constructive solution warns drivers about the intention of road users to use the pedestrian crossing;

on the columns around the perimeter of the security area, generators of a yellow visible laser beam with built-in laser devices are installed, this additionally warns drivers of their intention to use a pedestrian crossing;

with the ability to turn on generators of laser visible beams of red and yellow, as well as prism laser devices of red and yellow color by a signal transmitted from sensors for detecting the presence of objects on the safety site, which creates an increase in the safety of pedestrians at an unregulated crossing by timely providing information to the driver about the presence of waiting pedestrians, including in the form of a small dog.

From the analysis of scientific, technical and patent literature, the totality of the declared features is unknown, this allows us to conclude that the proposed technical solution complies with the criterion of "novelty".

Brief description of the drawings

The essence of the claimed system is illustrated in Fig. 1 depicting a pedestrian crossing in the mode before the pedestrian appears on the safety site, including: 1 - an object presence detection sensor for passing through the pedestrian crossing; 2 – safety platform for pedestrians; 3 – columns with installed generators of red laser beams and prism laser devices; 4 - columns with installed generators of yellow laser beams and prism laser devices; 5 - red laser beam generator; 6 - prism laser devices generating red beams; 7 - red laser beam generator; 8 - prism laser devices generating red beams;

In FIG. 2 shows a pedestrian crossing in the mode after the appearance of a pedestrian on the safety site, including: 1 - a sensor for detecting the presence of objects for passing through the pedestrian crossing; 2 – safety platform for pedestrians; 3 – columns with installed generators of red laser beams and prism laser devices; 4 - columns with installed generators of yellow laser beams and prism laser devices; 5 - red laser beam generator; 6 - prism laser devices generating red beams; 7 - yellow laser beam generator; 8 - prism laser devices generating yellow beams; 9 - red laser beam; 10 - red laser plane with a visible light line on the roadway; 11 - yellow laser beam; 12 - yellow laser plane with a visible light line at the pedestrian crossing; 13 - pedestrian; 14 - unregulated pedestrian crossing

Implementation of the invention

The warning system for road users at an unregulated pedestrian crossing works as follows.

Unregulated pedestrian crossing 14, limited by four columns 3, each of which has built-in sensors for detecting the presence of objects 1 for passing through the pedestrian crossing and generators of a visible red laser beam 5 with built-in red prism laser devices 6 operating in a horizontal direction perpendicular to the carriageway from one column to another, located on different sides of the roadway.

To reduce the risk of rash actions on the part of pedestrians and drivers, and giving the pedestrian 13 the opportunity to assess the traffic situation before he starts moving, the sensors for detecting the presence of objects 1 for passing through the pedestrian crossing installed in additional columns 4, creating a safety platform 2 for the pedestrian 13 nearby with the carriageway of an unregulated pedestrian crossing 14, on columns 4 along the perimeter of the safety site 2, generators of a yellow visible laser beam 7 with built-in yellow prism laser devices 8 are installed. 8 comes from the transmission of a signal to them from sensors for detecting the presence of objects 1 in the form of a pedestrian 13 on the safety platform 2. At the same time, a red laser beam 9 will turn on, a red laser plane with a visible light line on the roadway 10, the laser beam will light color 11, yellow laser plane with visible light line at the pedestrian crossing 12.

Such a constructive solution improves the safety of pedestrians at an unregulated crossing by providing timely information to the driver about the presence of waiting pedestrians.
