detailed description

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

As shown in Fig. 1 and Fig. 2, respectively provide the structure schematic diagram and the circuit schematic diagram of the pedestrian crossing automatic warning system of the present utility model, it is made up of detection trigger unit 1, vehicle early warning prompt unit 2, crossing street track warning unit 3 and solar energy Composed of battery boards 4, a detection unit column 8 is fixed at the intersection to be detected, and a detection trigger unit 1 is fixed on the top of the detection unit column 8 for detecting pedestrians who are about to cross the road. When the detection trigger unit 1 detects that a pedestrian is about to cross the road, it sends a corresponding output signal to the control circuit 11 . The control circuit 11 controls the power on and off states of the vehicle warning prompt unit 1 and the street crossing track warning unit 3 according to the output signal of the detection trigger unit 1 .

The place ahead of the shown crossing is fixed with an early warning unit column 9, and the vehicle early warning prompt unit 2 is fixed on the top of the early warning unit column 9. When a pedestrian is about to cross the road, the vehicle early warning prompt unit 2 sends an early warning signal. The lower part of the vehicle warning prompt unit 2 shown is provided with luminous characters for prompting the driver, such as the luminous characters of "Pay attention to pedestrians crossing ahead", the middle part is provided with a standardized attention to pedestrian sign 7, and the upper part is provided with red strip warning lights 5 and The blue strip warning light 6 is to strengthen the further reminder to the driver by the flickering of the warning light.

The shown crossing track warning unit 3 is composed of a plurality of floor lamps, which are arranged at intervals on both sides of the zebra crossing, and further reminders to drivers are realized through the lighting and flickering of the floor lamps, which is more conducive to making the driver find that he is about to cross. Pedestrians on the road.
