Abstract

The present invention relates to a bus display for pedestrian safety. According to the present invention, a camera is put in front of a bus and a situation in front of the bus is shown through a screen attached to a side of the bus. Drivers can carefully pass while looking at a situation in front of the bus which was not conventionally visible, thereby protecting pedestrians. Since a distance sensor is attached to a front part of the bus, a camera image is transmitted to the screen only when there is a person in front of the bus, and in other cases, an advertisement screen is exposed, so a user can get fun and economical effects.

Description

보행자 안전을 위한 버스 디스플레이{Safe bus display for pedestrain}Safe bus display for pedestrain

정차한 버스의 옆을 지나가는 운전자는 버스 앞의 상황이 보이지 않기 때문에 버스 앞에서 갑자기 나타나는 보행자를 뒤늦게 알아채고 사고로 이어지는 경우가 있다. 버스 앞의 상황을 카메라로 찍고 버스 옆에 부착한 디스플레이 장치에 보여줌으로써 사고를 예방하는 방법이다.The driver passing by the side of the stopped bus may not notice the situation in front of the bus, so it may be late to notice a pedestrian appearing in front of the bus and lead to an accident. This is a way to prevent accidents by taking a picture of the situation in front of the bus and showing it on a display device attached to the side of the bus.

라즈베리파이와 같이 값싸게 컴퓨터의 기능을 구현할 수 있는 제품들이 시장에 많이 나타나게 되었다. 초음파 센서, 카메라, 디스플레이 장치등을 이용하여 버스 앞의 상황을 보여줄 수 있다.There are many products on the market that can implement computer functions inexpensively, such as Raspberry Pi. You can show the situation in front of the bus using an ultrasonic sensor, camera, or display device.

초음파센서는 버스 앞에 사람이 있는 지를 판단한다. 초음파센서에 의해 사람이 있다고 판단되면, 버스 앞면을 향하는 카메라를 동작시켜 영상을 찍는다. 이 영상을 버스 옆면에 부착된 디스플레이로 전송하여 버스 옆을 지나는 다른 운전자들이 보면서 직접 보이지는 않았던 버스 앞의 상황을 볼 수 있게 된다.The ultrasonic sensor determines if there is a person in front of the bus. If it is determined that there is a person by the ultrasonic sensor, the camera facing the front of the bus is operated to take an image. By sending this video to the display attached to the side of the bus, you can see the situation in front of the bus that was not directly seen by other drivers passing by the bus.

도2에서와 같이 버스 옆을 지나는 운전자는 버스 앞의 상황을 보지 못한다. 정차한 버스의 앞을 지나가는 보행자가 있는 경우, 다른 운전자가 알지 못하기 때문에 사고로 이어지는 경우들이 존재한다. 본 발명은 버스앞의 상황을 버스옆을 지나는 운전자들이 잘 알 수 있게 하는 장치를 고안하는 것이다. As shown in Fig. 2, the driver passing by the bus does not see the situation in front of the bus. When there is a pedestrian passing in front of a stopped bus, there are cases where an accident occurs because other drivers do not know. The present invention is to devise a device that allows drivers passing by the bus to know the situation in front of the bus.

컴퓨터의 역할을 하는 것은 라즈베리파이와 같이 장치를 이용할 수 있다. 거리를 측정하는 초음파센서, 버스 앞의 상황을 촬영하는 카메라, 버스옆면에 부착하여 버스 앞의 상황을 보여주는 디스플레이 장치를 활용한다.Acting as a computer, you can use a device like the Raspberry Pi. It utilizes an ultrasonic sensor to measure the distance, a camera to photograph the situation in front of the bus, and a display device attached to the side of the bus to show the situation in front of the bus.

버스앞의 상황을 다른 운전자들이 잘 볼 수 있게 하면서 보행자를 더 보호할 수 있다. 또한, 평상시에는 버스 디스플레이에 광고영상이 나오다가 버스 앞에 보행자가 나타나면 버스 앞의 영상으로 바뀌게 된다. 운전자들은 버스 앞의 상황을 주시하기 위해 버스 디스플레이를 주목하기 때문에 평상시에 나오는 광고 영상을 잘 보게 된다. 이런 특성 때문에 주목성이 높은 광고판의 역할을 할 수 있다. 광고판으로 사용할 수 있기 때문에 본 발명품의 제작비는 충분히 광고비 수익으로 대체할 수 있으며, 결과적으로 발명품제작에 드는 비용에 드는 부담은 거의 없게 된다.Pedestrians can be further protected by allowing other drivers to see the situation in front of the bus. In addition, in normal times, an advertisement image appears on the bus display, and when a pedestrian appears in front of the bus, it is changed to the image in front of the bus. Because drivers pay attention to the bus display to keep an eye on the situation in front of the bus, they can watch the advertisement video that comes out on a regular basis. Because of these characteristics, it can serve as a highly noticeable billboard. Since it can be used as a billboard, the production cost of the present invention can be sufficiently replaced with the profit of advertising costs, and as a result, there is little burden on the cost of manufacturing the invention.

도1은 본 발명을 구성하는 모든 요소들이 나타나 있다. 보행자(101)이 버스 앞을 지나가면, 초음파센서(102)가 이를 감지한다. 이 때 카메라(103)이 동작을 시작하게 되고 찍은 영상을 버스 옆면 디스플레이(104)로 전송한다. 이 모든 과정은 라즈베리파이와 같은 제어장치(105)를 이용하여 통제한다.1 shows all elements constituting the present invention. When the pedestrian 101 passes in front of the bus, the ultrasonic sensor 102 detects it. At this time, the camera 103 starts to operate and transmits the captured image to the bus side display 104. All of these processes are controlled using a control device 105 such as a Raspberry Pi.

초음파센서는 초음파를 발생하는 송신부와 수신부로 구성이 되어있다. 제어장치에서는 초음파센서를 이용하여 프로그램할 수 있는데, 신호를 보내고 수신한 시간을 이용하여 실제 거리를 계산할 수 있다. 거리를 너무 가깝게 설정해두면 사람이 지나가는 것을 판단하지 못할 수 있으며, 너무 멀리 설정해두면 사람이 없는데도 다른 물체를 사람으로 오판할 수 있다. 거리값은 실제 환경에서 적절하게 설정해두어야 한다.The ultrasonic sensor is composed of a transmitter and a receiver that generate ultrasonic waves. The control device can be programmed using an ultrasonic sensor, and the actual distance can be calculated using the time that the signal was sent and received. If you set the distance too close, you may not be able to judge a person passing by, and if you set too far, you may misinterpret other objects as people. The distance value should be set appropriately in the real environment.

초음파센서에서 거리를 측정한 결과 어느 일정 거리보다 가깝다면 카메라를 동작시키고 디스플레이로 전송한다. 디스플레이 장치에는 평상시에는 광고 영상이 나오게 설정을 해둔다. 평소에는 광고영상이 나오고 조심해야 할 때에는 카메라 영상이 나오기 때문에 오히려 주목성이 더 높아지게 된다.As a result of measuring the distance from the ultrasonic sensor, if it is closer than a certain distance, the camera is operated and transmitted to the display. The display device is set so that the advertisement image is normally displayed. Advertisement images usually come out, and camera images come out when you need to be careful.
