Zebra crossing pedestrian monitoring and warning device based on laser inspection

Abstract

The invention relates to a zebra crossing pedestrian monitoring and warning device based on laser inspection. The current devices have bad using effects. The device of the invention comprises a pedestrian monitoring device, a control box and signal lamps, wherein the pedestrian monitoring device comprises two trigger gates respectively arranged at the start and end of a zebra crossing; each trigger gate comprises a laser emission column and a laser pick-off column arranged on a sidewalk respectively at two ends of the zebra crossing; the laser emission column of each trigger gate emits laser beam and the laser pick-off column of each trigger gate picks off the laser beam; when a pedestrian passes through the trigger gates, the laser beam is cut off; two rows of signal lamps are respectively arranged at two sides of the zebra crossing; and the control box is arranged on a telegraph pole of the sidewalk. The device of the invention adopts the pedestrian monitoring systems arranged at two ends of the zebra crossing, and each pedestrian monitoring system is additionally provided with a passing in and out direction judging function, thereby improving the efficiency of system operation. The device of the invention is more conductive to remind drivers to avoid collision to reduce hidden danger of traffic accidents.

Description

technical field [0001] The invention belongs to the field of laser detection and information transmission, and specifically relates to a device for identifying and judging by laser detection technology, reflecting the information of pedestrians on the zebra crossing on road signal lights, and reminding drivers of vehicles passing the zebra crossing to pay attention to avoiding. Background technique [0002] With the development of society, there are more and more vehicles running on urban roads; although pedestrian traffic lights are installed near some zebra crossings, pedestrians are still becoming more and more dangerous when crossing the road (even on zebra crossings). When the weather is bad and the sky is dark, it becomes especially dangerous for pedestrians to cross the zebra crossing when encountering speeding vehicles, vehicles running red lights and vehicles changing lanes illegally. Sometimes even if the driver finds pedestrians on the zebra crossing at a relative...

AI Technical Summary

Problems solved by technology

The unit does not detail the system's on-time and off-time, so overall system usage is less efficient

Second, the device only relies on a single infrared laser transmitter and a single infrared laser receiver to monitor pedestrians, and cannot judge whether a pedestrian is entering or exiting the zebra crossing, which makes the overall system have a high misjudgment rate

Third, the device installs the signal light on the light pole and hangs it a few meters above the road surface, which is easy for drivers to confuse it with traffic lights, and cannot play a very obvious warning role for passing vehicles
