KR20210094400A - The use of microwave and photo-sensor fusion system to keep traffic range safe. - Google Patents

Abstract

The existing method using only light (optical sensor) was mainly effective at night, but a traffic accident prevention system using microwaves was constructed by fusion of microwaves and light (optical sensor), so the system can be used for 24 hours, and the optical sensor compensates for the disadvantage that microwaves are absorbed by rain (water). By linking the vehicle, motorcycle, and passerby detected by the sensor with AI, an LED warning light when entering a vehicle, and a mobile phone application and a crossing speaker when a passerby enters a crossing while looking at their mobile phone are used to give a warning.

Description

{The use of microwave and photo-sensor fusion system to keep traffic range safe.}

The present invention relates to a crossing safety protection system that combines a microwave and optical sensor fusion system with ai to help vehicles and passersby pass more easily and safely.

While the technology continues to make rapid progress, on the other hand, the crossing safety system is not well developed, so the number of fatalities or injuries in traffic accidents continues to increase. In particular, the damage to the elderly and short children on the road behind the blind spot of a traffic accident is great. In addition, the number of pedestrian traffic accidents related to smartphones is increasing. This seems to be because the only safety device at the crossing is simply a traffic light. Through this, I think that it is necessary to change the perspective of traffic safety and the direction of the budget.

Although it is currently installed in a way using light (optical sensor) on the road, it is mainly effective only at night. It is a good example that traffic, which was initially vehicle-centered, has changed to pedestrian-centered, but now is the time to establish a transportation culture centered on mutual respect between vehicles and pedestrians based on advanced technology.

An object of the present invention is to reduce a traffic accident on a road behind a traffic accident blind spot, and to make a safer road by collecting data of drivers and pedestrians.

In addition, we want to create big data by collecting various information on the road with sensors, and based on this, create a situation where optimal traffic can be maintained, giving pedestrians safety and drivers attention to things they have not seen before.

When a vehicle enters by using a microwave and light sensor, it notifies the vehicle's entrance speed with LED lights as well as voice guidance. At this time, if the vehicle is speeding, the speed warning alarm and LED light blink.

In addition, when going straight and turning left/right, if there is a pedestrian, an LED warning is also provided. Pedestrians are also notified that a vehicle is approaching with LED lights, and the mobile phone app “crossing safety integrated app (tentative name)” and microwave are linked. Using the 2.4G (wifi) band used by this mobile phone, the mobile phone recognizes the crossing wifi id and runs the mobile phone app. Through this app, if the phone's screen is still active until the moment you enter the crossing, it will trigger an alarm on the phone and alert the speaker at the crossing, helping pedestrians to pause their use of the phone.

As described above, by effectively acquiring information of vehicles and pedestrians regardless of day or night and any weather and using the established real-time road traffic information situation to dramatically increase the interaction between pedestrians and vehicles, safety for pedestrians and better safety for drivers It can improve the convenience of transportation by providing wide and clear information.

In addition, by linking with the smart phone used by many people, it is possible to dramatically prevent traffic accidents caused by the frequent use of smart phones.

In addition, not only visual notifications but also auditory notifications come together so that more and more people can know more and more firmly by not relying on only one sense.

1 is an exemplary view of the recognition range when the present invention is implemented.
2 and 3 are explanatory views of a notification display method when the present invention is implemented.
4 and 5 are exemplary views of the notification display of the present invention.

The existing method using only light (optical sensor) was mainly effective at night, but the traffic accident prevention system using microwaves was constructed by fusion of microwaves and light (optical sensors), so it can be used for 24 hours and can be used without microwaves. The optical sensor compensates for the disadvantage of being absorbed by (water). By linking vehicles, motorcycles, and passers-by detected by the sensor with AI, LED warning lights when entering a vehicle, and when passers-by enter a crossing while looking at their mobile phone, a mobile phone application and a crossing speaker are used to give a warning.
