Description

Piezoelectric Pedestrian Crossing Safety Warning 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.

Contents of the invention

In order to improve the safety of pedestrians crossing pedestrian crossings at night and avoid collision accidents between pedestrians and vehicles, the utility model provides a safety reminder device for pedestrians crossing the street at night. Finding pedestrians can solve the problems of difficult popularization and high cost of existing safety reminder technology.

The technical scheme adopted by the utility model to solve the technical problem is: a ceramic piezoelectric sheet and a pressure-sensitive capacitive switch are installed under a wear-resistant rubber film type crosswalk. The electric energy generated by the piezoelectric sheet is sent to the energy storage battery through the connection line for storage; when pedestrians cross the street at night, the photosensitive control switch is turned on, and the electric energy generated by the ceramic piezoelectric sheet is sent to the energy storage battery through the connection line. Simultaneously, the piezo-capacitance switch is turned on, prompting the lamp post to emit light, and warning the motor vehicle driver.

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 ceramic piezoelectric sheet, and the rubber shock-absorbing block is connected to the wear-resistant rubber film-type crosswalk , The bottom is connected with the ceramic piezoelectric sheet.

In the technical solution of the utility model, it also has the following technical features: the ceramic piezoelectric sheet and the energy storage battery are connected in parallel.

In the technical solution of the utility model, it also has the following technical features: the prompt lamp post adopts three-color LED lights, and the three colors include yellow, orange and red.

The beneficial effect of the utility model is that when a pedestrian prepares or is crossing the pedestrian crossing line, the vehicle driver is warned in advance by reminding the light signal sent by the lamp post to prevent traffic accidents. The device has a simple structure, low manufacturing and installation costs, no special requirements for pedestrians and motor vehicles, good universal applicability, and obvious prompting effect.
