Solar intelligent zebra crossing device

Abstract

The invention discloses a solar intelligent zebra crossing device. The solar intelligent zebra crossing device comprises a solar power supply system, a pedestrian sensing and detecting system, a PLC (programmable logic controller) control system, a zebra crossing LED indicator light system and a voice warning system. When pedestrians go into a zebra crossing area, pressure sensors transmit sensing signals to the control system, the control system judges that the pedestrians walk out of the zebra crossing or to the opposition direction of the zebra crossing. When the pedestrians walk to the counter road via the zebra crossing, LED lamps embedded on the zebra crossing emit conspicuous red light to prompt passing vehicles of no entry so as to avoid the pedestrians in advance. When the vehicles pass and the pedestrians are detected at a starting line of the zebra crossing, the voice warning system can prompt the pedestrians of no entry. The solar intelligent zebra crossing device is powered by solar energy, energy source is saved, cables are not needed to be paved, mounting of the device is convenient, avoiding of the vehicles and safety passing of the pedestrians are facilitated, and traffic potential hazards are reduced.

Description

Technical field [0001] The invention relates to a solar energy intelligent zebra crossing device, that is, when pedestrians or vehicles pass by, the zebra crossing can automatically emit red light and voice to warn passing vehicles, improve safety and prevent problems before they happen, belonging to the technical field of traffic safety. technical background [0002] Common zebra crossings are mostly made of paint spraying, which is used to warn vehicle drivers to avoid pedestrians crossing the road during driving, but after a period of use, the paint is easy to fade or even peel off, thus reducing the warning effect , even if it is regularly maintained and repainted, sometimes the driver will relax his vigilance due to his own fatigue, or sometimes it is difficult for the driver to see the pedestrians passing by the roadside under the conditions of dim light and partially blocked view, which will cause unfavorable As a result, in order to improve the safety factor of zebra...

Problems solved by technology

[0002] Common zebra crossings are mostly made of paint spraying, which is used to warn vehicle drivers to avoid pedestrians crossing the road during driving, but after a period of use, the paint is easy to fade or even peel off, thus reducing the warning effect , even if it is regularly maintained and repainted, sometimes the driver will relax his vigilance due to his own fatigue, or sometimes it is difficult for the driver to see the pedestrians passing by the roadside under the conditions of dim light and partially blocked view, which will cause unfavorable As a result, in order to improve the safety factor of zebra crossings, relevant staff put forward a series of measures, such as the use of colored zebra crossings and other technologies. The Zebra Crossing Pedestrian Monitoring and Warning Device” involves monitoring whether there are pedestrians passing through the laser beams placed on both sides of the sidewalk. Once pedestrians pass, the road stud lights will flash at a certain frequency. This way, to a certain extent, long-term work of the lamps is avoided. However, when placed next to the road, the laser beams on both sides of the sidewalk are difficult to be in harmony with the surrounding landscape of the road, which has a certain impact on the city appearance. Not only that, because this method can only detect the laser beams passing between the two laser beams pedestrians, it is difficult to detect the detour pedestrians, so there are still some potential safety hazards. In view of the existence of the above-mentioned imperfect solutions and problems, people urgently need a new technical solution that can be produced as soon as possible
