Description

Pedestrian crossing active warning system

technical field

The utility model relates to a traffic safety warning device, in particular to an active warning system for pedestrians crossing the street.

Background technique

In today's society, cherishing life is already a common topic of people's livelihood. In terms of traffic safety, the safety and security of pedestrians is now a social issue that people pay attention to and pay attention to. With the comprehensive development of traffic facilities, the safety protection of pedestrians is becoming more and more perfect, and crosswalks are indicator signs specially set up for pedestrians crossing the street. But now many pedestrian crossings on the street are not perfect, especially at night, the warning function of the pedestrian crossing is not obvious, the driver often ignores the existence of the pedestrian crossing, when a pedestrian passes the pedestrian crossing, the driver cannot find it in time, and it is very likely that the avoidance is not timely Serious traffic accidents may cause unpredictable injuries to people.

Contents of the invention

The technical problem to be solved by the utility model is to provide an active warning system for pedestrians crossing the street, which can prompt whether there are pedestrians in front of the vehicle at night, and make corresponding judgments in time.

The technical scheme of the utility model is as follows: an active warning system for pedestrians crossing the street, which includes a column, a solar photovoltaic panel and a light control sensor arranged on the column, and a rechargeable battery electrically connected to the solar photovoltaic panel, which is characterized in that An infrared human body sensor is arranged on the column, and a controller is arranged inside the column. The light control sensor, the infrared human body sensor and the LED light are all electrically connected to the rechargeable battery, and the controller is also electrically connected to the sidewalk. Luminous road studs and a luminous signboard set in the middle of the column.

The specific features of this program also include that a crossbeam is arranged on the upper part of the column, an LED supplementary light is arranged at the end of the crossbeam, and an infrared human body sensor is arranged in the middle of the crossbeam.

A wear-resistant rubber plate is arranged on the road surface on both sides of the bottom of the column, and a waterproof travel switch and a rubber shock absorber are arranged under the wear-resistant rubber board, and the waterproof travel switch is electrically connected with the luminous spike and the luminous signboard.

The infrared human sensor is Panasonic AMG8831.

The light control sensor is Schneider Electric Co., Ltd. IC2000. The controller is brand: CREATOR and model: CR-PGMⅢ produced by Guangzhou Tianyu Chuanggao Electronic Technology Co., Ltd.

Beneficial effects of the utility model: in the active warning system for pedestrians crossing the street, the light control sensor located on the column senses that the light source cuts off the power supply during the daytime, and the controller is in a closed state, and at the same time, the solar photovoltaic panel converts solar energy into electrical energy and stores it in the rechargeable battery , the night light dims and the light control sensor energizes and activates the controller. Due to the double insurance of infrared human body sensor and travel switch control, it successfully avoids the traffic accidents that are likely to occur when pedestrians cross the street at night. The infrared human body sensor has a sensing range of up to 180 degrees and a sensing distance of 12 meters. The assembled luminous road studs can display the road direction and the position of road obstacles with the best visual effect, and can be clearly seen even in rainy and foggy weather. At the same time, there are projected warning lines on the ground, even if there is snow or sundries covered, the luminescence will not be affected. The utility model is an active warning system for pedestrians crossing the street, which is safe, practical and stable.

Detailed ways

As shown in Figure 1, an active warning system for pedestrians crossing the street includes a column 1, a solar photovoltaic panel 6 and a light control sensor arranged on the column 1, and a rechargeable battery electrically connected to the solar photovoltaic panel 6. 1 is provided with an infrared human body sensor 3, and a controller 8 is arranged inside the column 1. The light control sensor and the infrared human body sensor 3 are all electrically connected to the rechargeable battery, and the controller 8 is electrically connected to the sidewalk. The luminous road stud 7 on the side and the luminous signboard 9 arranged in the middle of the column 1. A crossbeam 2 is arranged on the top of the column 1, an LED lamp 4 is arranged at the end of the crossbeam 2, and an infrared human body sensor 3 is arranged in the middle of the crossbeam 2. Infrared human sensor 3 is Panasonic AMG8831.

A wear-resistant rubber plate 10 is arranged on the road surface on both sides of the bottom of the column 1, and a waterproof travel switch and a rubber shock absorber are arranged below the wear-resistant rubber plate 10. connect.

High-definition video analysis camera 5 is also arranged on roadside column 11, and high-definition video analysis camera 5 is Hangzhou Hikvision Digital Technology Co., Ltd. model: OpenCV246.

During use, when pedestrians pass through the street at night, the infrared human body sensor 3 installed on the street roadside column 11 detects the human body signal through thermal detection, and the luminous signboard 9 is turned on by the controller 8 to emit light, and the luminous road stud 7 simultaneously flashing. The LED light 4 on the beam 2 is turned on to illuminate the zebra crossing area. When the infrared human body sensor 3 detects people all the time, the controller 8 automatically performs time multiple superposition (time adjustable) according to the time when a pedestrian crosses the street.

When the infrared human body sensor falsely reports or does not report due to reasons such as air temperature or dust, the controller 8 opens the waterproof travel switch installed on the ground, and senses pedestrians crossing the street through the waterproof travel switch under the wear-resistant rubber plate 10, and the wear-resistant rubber plate There is a rubber damping block between 10 and the travel switch, and sends a signal to the controller 8, and the controller 8 luminous signboard 9 and the luminous road stud 7 are luminous. The LED light 4 lights up to illuminate the zebra crossing area, and when the infrared human body sensor 3 does not detect pedestrians, the sensor switch is automatically turned off to save energy.

The high-definition video analysis cameras 5 installed on both sides of the street can capture the facial feature pictures of passing pedestrians at high speed and compare them with the sensitive information of the background server in a timely manner (sensitive information refers to fugitives, missing persons, and other special personnel information) and finds matching information Immediately report to the relevant departments and promptly videotape and collect evidence.
