Description

The utility model relates to the field of construction, to devices for promptly notifying drivers of the presence of people at a pedestrian crossing.

Known devices for automatically controlling the operation of traffic lights at pedestrian crossings, containing traffic lights on a supporting tubular pole, control units and means for accommodating these blocks (RF Patent PM No. 70382 IPC G05G 1/00, publ. 01.20.2008)

A disadvantage of the known devices is the inability to account for the presence of pedestrians at the crossing. Red light is automatically turned on for vehicles regardless of the need to cross the street, which leads to an undesirable accumulation of vehicles before empty crossings, and ultimately traffic jams.

To prevent this, an unregulated pedestrian crossing was created, containing the information sign “Pedestrian crossing” on the supporting tubular pole, a signal lighting element located above the transition on the crossbar, supported by a pole, motion sensor, power supply, control unit, connecting nodes and means for placement of these blocks (RF Patent ПМ №101048 IPC E05F 9/00, published on January 10, 2011 - a prototype).

The disadvantage of this device, which we have chosen as a prototype for most of the matching features, is the placement of signal lighting on the crossbar above the transition, which prevents the passage of large vehicles.

The problem solved by the use of the claimed utility model is to increase the degree of safety of an unregulated pedestrian crossing.

The technical essence of the claimed solution lies in the fact that in the well-known pedestrian crossing, containing the information sign “Pedestrian crossing” on the supporting tubular pole, an element of signal lighting, placed above the transition on the crossbar, supported by a pole, motion sensor, power source, control unit , connecting nodes and means for placing these blocks, the signal lighting element is made in the form of a lighting cord from series-connected diodes located around the perimeter of inform translationally-mark index, the motion sensor is designed as a switch presence and a power source - in the form of solar cells on the area information and the index mark, wherein all the connecting units are mounted in the cavity of the tubular support column.

The implementation of the element of signal lighting in the form of a lighting cord of series-connected diodes located along the perimeter of the information and index sign, provides a bright illumination of the sign and indicates the presence at the transition of people whom the driver for some reason does not see.

The implementation of the motion sensor in the form of a presence relay provides an alarm not only when driving, but also when the pedestrian stops at any section of the transition.

The implementation of the power source in the form of solar panels on the area of the information sign, despite the fact that all the connecting nodes are mounted in the cavity of the supporting tubular column, provides a compact device and energy savings.

Figure 1 shows a diagram of the proposed pedestrian crossing; figure 2 is a block diagram of the signal lighting.

Safe pedestrian crossing (Fig. 1) contains information signs “Pedestrian crossing” in the form of rectangular panels 1 with a conditional image of a walking person, placed on supporting tubular posts 2, installed on both sides of the road immediately before the crossing.

Along the perimeter of the shields 1 are placed lighting cords 3 of series-connected diodes, and on the area of the shields are solar panels 4 that provide power to the diodes of the cords 3. To turn on the diodes, either a mechanical switch 5 or a presence relay 6 with a sensor mounted next to the switch 5 is used.

To stabilize the operation of the presence relay 6 (figure 2), an electronic delay relay 7 and a battery 8 are used, connected in parallel with each other and with the diodes of the cord 5, while the presence relay 7 is connected to the diodes of the cord 5 in series through the electronic delay relay 7. All of these nodes placed in the cavity of the tubular posts 2.

The claimed device operates as follows.

Before the pedestrian enters the crossing, the presence relay 6 is activated or the pedestrian presses the switch 5 button for insurance. In this case, the diodes of the cord 3 are turned on, illuminating the area of the shield 1 of the information sign “Pedestrian crossing”, thereby signaling to drivers that people are at the crossing. Delay relay 7 provides a predetermined mode of operation of the device.
