Description

The utility model relates to the light signaling technique, namely to traffic lights, providing pedestrians with additional information about the burning time of traffic signals in dynamic mode.

There is a pedestrian information board containing a case with a translucent screen, behind which there is a light source made in the form of a matrix of identical LEDs forming a digital time indicator, a control unit with a microprocessor controller and a power supply (see RF certificate for utility model No. 20982, G08G 1 / 095, published on December 10, 2001, BIPM No. 34 (2) - 2001, p. 413).

Known electronic indicator for displaying the time remaining until the change of the traffic light, containing a housing with a translucent screen, behind which is a light source made in the form of a matrix of identical LEDs forming a digital time indicator, a control unit with a microprocessor controller and a power supply, while the matrix LEDs are made on identical two-color or three-color LEDs (see RF patent for utility model No. 61915, G08G 1/095, published on March 10, 2007. BIPM No. 7 (3) - 2007, p. 715).

The disadvantages of the known devices are the lack of clarity in the display of the displayed signals on the information boards, which in turn leads to a decrease in the level of road safety, as well as insufficient information boards for pedestrians, including pedestrians with no or limited vision or hearing.

The problem solved by the utility model is to increase the information content of the structure, leading to an increase in road safety.

This object is achieved in that the inventive device containing a housing with a translucent screen, behind which is a light source made in the form of a matrix of identical LEDs forming a digital time indicator, a control unit and a power supply according to a utility model, the housing is made of two sections located under each another, while in the upper section of the housing there is a matrix of red LEDs glowing, forming a stylized figure of a standing person, and a matrix of green LEDs candle forms forming a digital indicator with a countdown in seconds, and in the lower section of the case there is a matrix of green LEDs that form a stylized figure of a walking person, in addition, the control unit includes elements for automatically adjusting the volume and intermittent sound depending on time actions of a green traffic light.

Distinctive features of the prototype are:

- the case with a translucent screen is made of two sections located one below the other;

- in the upper section of the housing there is a matrix of red LEDs glowing, forming a stylized figure of a standing person, and a matrix of green LEDs glowing, forming a digital indicator with a countdown in seconds;

- in the lower section of the case is a matrix of green LEDs that form a stylized figure of a walking person;

- the control unit includes elements for automatically adjusting the volume and intermittent sound depending on the duration of the green traffic light.

Implementation of a pedestrian traffic light information board comprising a body of two sections located one above the other, in the upper of which there is a matrix of red LEDs glowing, forming a stylized figure of a standing person and a matrix of green LEDs glowing, forming a digital indicator with a countdown in seconds, and in the lower section of the case there is a matrix of green LEDs that form a stylized figure of a walking person, as well as the inclusion of an electric To automatically adjust the volume and intermittent sound depending on the duration of the green traffic light, it can increase the information content of pedestrians, including pedestrians with no or limited vision and hearing, which in turn leads to increased road safety.

Devices with the claimed combination of distinctive features in the patent and scientific literature are not found.

The device is illustrated by drawings, in which Fig. 1 is a view of a direct information board of a pedestrian traffic light with a green traffic light enabled, and in Fig. 2 is the same view of a direct information board, but with a red traffic light that prohibits movement, in Fig. 3 - side view.

The device includes a housing consisting of an upper 1 section and a lower 2 sections located one below the other, a translucent screen 3 of the upper and lower sections made of impact-resistant material, a visor 4 above the upper and lower sections of the housing, and a matrix of red LEDs is located inside the upper 1 section of the housing forming a stylized figure of a standing person 5, and a matrix of green LEDs that form a digital indicator 6 with a countdown in seconds, a matrix of light is placed inside the lower 2 section of the housing green luminescence diodes forming a stylized figure of a person walking 7, control unit and power supply (not shown).

The device operates as follows.

When the signal allowing pedestrians to go to the pedestrian traffic light from the traffic light controller is turned on, in the upper 1 section of the casing the digital indicator 6 is sequentially lit by green LEDs, showing the time, in seconds, left for the pedestrian to cross the carriageway, while at the same time in the lower part 2 of the body on the scoreboard a stylized figure of a walking person 7 is displayed, formed by green LEDs. Simultaneously with the start of the countdown, an intermittent sound signal is generated with a frequency of 3.0 kHz ÷ 4.5 kHz, which 5 seconds before turning off increases the sound frequency, i.e. is becoming more frequent. The sound signal is supplied by a sound siren (not shown) by a control signal from a microprocessor (not shown). After the zeroed indication appears on the scoreboard in the top 1 section of the case, the prohibition signal to the pedestrian is turned on in this section in the form of a stylized figure of a standing person 5 from red LEDs. At the same time, in the lower 2 sections of the case, the matrix of green LEDs with the image of a walking person 7 is not lit on the scoreboard and an audio signal is not supplied.

The power sign of the pedestrian traffic light is supplied from an alternating current network of 220 V and a frequency of 50 Hz, power consumption should be no more than 35 W. The temperature range during operation of the inventive device is from -45 ° C to + 65 ° C.

The information sign of the pedestrian traffic light is intended for informing pedestrians when crossing the carriageway. Its application allows to ensure high reliability, high information content of the design, as well as pedestrian safety.

Prototypes of the pedestrian traffic light information board are made and tested in operation. In the manufacture and operation of their benefits were confirmed.
