Abstract

A pedestrian traffic accident prevention device is disclosed that alerts a driver of a traveling vehicle by blinking a warning light when a pedestrian crosses a crosswalk. At least one warning light is installed on the road surface of the traffic light body or the starting line of the crosswalk and flashes for a set time according to the control signal. At least one pair of human body detection sensors are installed at one end and the other end of both sides of the crosswalk to detect the body of the pedestrian and output a detection signal. The control unit generates the control signal for blinking the at least one warning light according to the detection signal from the at least one pair of human body detection sensors.

Description

Walker traffic accident preventing apparatus

The present invention relates to a pedestrian traffic accident prevention device, and more particularly to a device for preventing a traffic accident for pedestrians crossing the crosswalk.

In general, the purpose of the vehicle is to provide convenience to the user as a means of transportation. For this purpose, automobiles are not only a means of transportation but they are becoming an integral part of their lives and social life. With this social trend, the number of cars owned has continued to increase, which has long exceeded 10 million in Korea. On the other hand, the number of cars owned in Korea has already entered the ranks of advanced countries, but in proportion to the population, car accidents are notorious as the world's number one.

The number of vehicles is rapidly increasing as the national economy and road traffic develop. At present, the rapid increase in the number of vehicles not only increases traffic, but also the damage of people and objects caused by the increase in proportion to the increase of vehicles. have. In particular, despite the fact that pedestrian traffic lights are installed on the crosswalks, traffic accidents frequently occur, and children's traffic accidents occurring in front of the school are becoming more social problems. However, despite the increase in pedestrian traffic accidents on pedestrian crossings as described above, the traffic light system that regulates vehicles and pedestrians on current pedestrian crossings does not change much compared to the past, and extends the lifespan of light bulbs used for traffic lights or the brightness of traffic lights. The situation is only to improve. In other words, the crosswalk equipped with the pedestrian traffic light as described above is unclear at night or during a natural phenomenon, for example, when the road is short in the daytime, such as when the fog is heavy or there is a lot of rain. Vehicle drivers are more likely to cause traffic accidents, and pedestrians often cross pedestrian crossings or have accidents while the green traffic light is on, reducing traffic accidents between vehicles and pedestrians. Was limited.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and an object thereof is to provide a pedestrian traffic accident prevention device that alerts a driver of a driving vehicle by flashing a warning light when a pedestrian crosses a crosswalk. .

In order to achieve the above object, the pedestrian traffic accident prevention device according to the present invention is installed on the road surface of the traffic light body or the starting line of the crosswalk and at least one warning light flashing for a set time according to the control signal; At least one pair of human body detection sensors installed at one end and the other end of both sides of the crosswalk to detect a body of a pedestrian and output a detection signal; And a control unit for generating the control signal for blinking the at least one warning light according to the detection signal from the at least one pair of human body detection sensors.

Preferably, the set time has a value proportional to the length of the crosswalk. More preferably, the at least one warning light provided on the road surface of the starting line of the crosswalk is located between each lane or in the center of each lane. Most preferably, said at least one warning light is a light emitting diode. The pedestrian traffic accident prevention apparatus of the present invention further includes a timer that counts the set time and generates a flashing operation control signal to provide the at least one warning light so that the at least one warning light blinks during the set time.

According to the present invention, when a pedestrian crosses a pedestrian crossing, a warning light blinks to warn the driver of the driving vehicle, thereby effectively preventing personal injury due to a traffic accident.

Hereinafter, an apparatus for preventing pedestrian traffic accidents on a crosswalk according to an embodiment of the present invention will be described in detail with reference to the accompanying example drawings.

1 is a block diagram showing the configuration of a pedestrian traffic accident prevention device on a crosswalk according to an embodiment of the present invention.

FIG. 2 is a view illustrating a state in which a human body sensor and a warning light illustrated in FIG. 1 are applied to a crosswalk.

The pedestrian traffic accident prevention apparatus according to the embodiment of the present invention includes at least one warning light 110, at least one pair of human body detection sensor 120, and the controller 130.

At least one warning light 110 is installed on the road surface of the starting line of the traffic light main body 200 or the crosswalk 210 and flashes for a set time according to the control signal. The set time has a value proportional to the length of the crosswalk. The at least one warning light 110 installed on the road surface of the starting line of the crosswalk is located between each lane or in the center of each lane. The at least one warning light 110 is preferably a light emitting diode.

At least one pair of human body detection sensors 120 are installed at one end and the other end of both sides of the crosswalk to detect a body of a pedestrian and output a detection signal.

The controller 130 generates the control signal for blinking the at least one warning light 110 according to the detection signal from the at least one pair of human body detection sensors 120.

The pedestrian traffic accident prevention apparatus of the present invention counts the set time to generate a flashing operation control signal so that the at least one warning lamp 110 blinks during the set time and provides the timer 140 to provide the at least one warning lamp. More).

Although the present invention has been described as a specific preferred embodiment, the present invention is not limited to the above-described embodiments, and the present invention is not limited to the above-described embodiments without departing from the gist of the present invention as claimed in the claims. Anyone with a variety of variations will be possible.

The pedestrian traffic accident prevention device on the crosswalk according to the present invention can be applied to a circuit walkway.
