Description

Solar-powered Pedestrian Crossing Safety Prompt Device at Night

Technical field

The utility model relates to a traffic safety prompting device, in particular to a device for prompting drivers whether there are pedestrians crossing the street through light signals at night.

Background technique

At present, when pedestrians cross pedestrian crossing lines at night, in addition to avoiding collisions through visual inspection by themselves and motor vehicle drivers, the safety measures adopted can be summarized into two categories:

The first category is pedestrian safety protection measures, which is to enhance the driver's visibility by wearing clothing with reflective substances. In addition to special reflective vests worn by special staff, clothing with reflective patterns is also in a certain range is adopted within.

The characteristics of such measures are: reflective clothing will produce obvious reflections under the illumination of car lights, which is convenient for drivers to observe pedestrians who are crossing pedestrian crosswalks, so as to take measures to slow down and avoid collisions between people and vehicles. However, due to the particularity of fabrics and styles of this type of clothing, it is difficult to promote it except for certain groups of people such as traffic police and environmental sanitation.

The second category is vehicle active safety protection devices. In addition to the enhancement of the brightness of the car lights and the improvement of the visual field, it also includes an infrared night vision system. Ordinary car high beams can only shine 150 meters away. In the case of poor visibility at night, the lighting distance is shorter, and it is difficult to observe early. Pedestrians who are crossing the pedestrian crossing line, and the infrared detection device can detect any heating objects, including pedestrians, up to 750 meters away.

The characteristics of this type of device are: Although the technology is advanced and the detection accuracy is high, it requires computer imaging processing and displays it on the head-up display in the vehicle, which increases the manufacturing cost of the vehicle. Currently, only a very small number of high-end cars use this type of technology.

In order to improve the safety of pedestrians crossing the pedestrian crossing line at night and avoid collision accidents between pedestrians and vehicles, the utility model provides a pedestrian crossing safety prompt device at night. The early detection of pedestrian light signals by motor vehicle drivers can solve the problems of difficult popularization and high cost in the existing safety reminder technology.

The technical scheme adopted by the utility model to solve the technical problem is: a pressure-sensitive capacitive switch is installed under the wear-resistant rubber film type crosswalk, and when pedestrians cross the street at night, the photosensitive control switch and the pressure-sensitive capacitive switch are in the on state at the same time. The prompting lamp post will emit light to achieve the purpose of warning motor vehicle drivers. The pedestrian crossing safety reminder device at night uses sunlight as energy, and the solar cell module converts the light energy into electrical energy and stores it in the battery, which is used to supply power to the high-power LED light source installed on the reminder lamppost. The ambient brightness is distinguished through the photosensitive control switch. Ensure that the device is turned off during the day and in normal operation at night.

In the technical scheme of the utility model, it also has the following technical features: a rubber damping block is installed between the wear-resistant rubber film-type crosswalk and the pressure-sensitive capacitance switch, and the rubber shock-absorbing block is connected to the wear-resistant rubber film-type crosswalk , the following is connected with the piezo-capacitance switch.
