Liftable warning device for pedestrians crossing zebra crossing

Abstract

The invention provides a liftable warning device for pedestrians crossing a zebra crossing. The liftable warning device comprises a device base and a solar warning device; a lithium battery is arranged on one side inside the device base, and an actuator sliding way and an actuator are arranged on the other side face of the device base; the solar warning device comprises a shell, an integrated LEDlamp, an electroplated reflector, a solar top plate, a photoresistor and an infrared sensor, and the bottom of the shell is fixedly connected with the actuator; the integrated LED lamp is fixedly connected to the right side face of the shell and embedded in the electroplated reflector, and the solar top plate is arranged at the top of the shell; and the photoresistor and the infrared sensor are arranged inside the solar top plate in parallel, and the photoresistor and the infrared sensor are electrically connected with the actuator. The warning devices are arranged on the two sides of the zebra crossing, when the pedestrians want to cross the zebra crossing, after the infrared sensors detect the pedestrians, the actuators are started, the solar warning devices rise from the underground, the LED lamps are lightened, and then the effect of warning vehicles running on the two sides of the zebra crossing to reduce the speed is achieved.

Description

technical field [0001] The invention relates to the technical field of traffic safety facilities, in particular to a liftable warning device for pedestrian crossing zebra crossings. Background technique [0002] In a dark environment or at an intersection without traffic lights, the zebra crossing cannot guarantee the absolute safety of pedestrians crossing the street. Especially on major traffic arterial roads in cities, the flow of vehicles is relatively high, and the side view of some running vehicles is easily blocked by the green belts on both sides of the road in case of a curve. When the vehicle is driving on a road section with a high design speed, if the driver does not reduce the speed in advance, but brakes suddenly to give way to pedestrians within the range of the zebra crossing, or encounters a pedestrian who does not follow the pedestrian crossing signal light and suddenly jumps out of the zebra crossing, etc. , It will also cause the driving driver to have n...

Problems solved by technology

When the vehicle is driving on a road section with a high design speed, if the driver does not reduce the speed in advance, but brakes suddenly to give way to pedestrians within the range of the zebra crossing, or encounters a pedestrian who does not follow the pedestrian crossing signal light and suddenly jumps out of the zebra crossing, etc. , it will also cause the driving driver to have no time to respond and cause emergency braking, which will lead to traffic accidents of serial rear-end collisions of subsequent vehicles. The above phenomenon is not uncommon.

Although most cities in China have proposed traffic management measures for road drivers to slow down and give way to pedestrians when encountering zebra crossings, in practice, due to individual differences between drivers and pedestrians, the above phenomena cannot be fundamentally eliminated
