이하에서는 도면을 중심으로 본 발명을 설명하고자 한다. Hereinafter, the present invention will be described with reference to the drawings.

도 1은 본 발명에 따른 후방감지용 초음파 거리센서를 구비한 자전거 후방감지시스템의 구성을 설명하기 위한 도면이다.BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a view for explaining a configuration of a bicycle rear detection system having an ultrasonic distance sensor for detecting a back according to the present invention.

도 1에 도시된 바와 같이, 본 발명은 후방물체감지센서부(100) 및 비상램프부(200)를 포함한다.As shown in FIG. 1, the present invention includes a rear object detecting sensor unit 100 and an emergency lamp unit 200.

후방물체감지센서부(100)는 운전자 전방에 구비되면, 운전자의 움직임을 접근하는 물체로 인식할 가능성이 있으므로, 운전자 후방인 자전거(10)의 일 측에 구비되는 것이 바람직하다. When the rear object detecting sensor unit 100 is provided in front of the driver, it is preferable that the rear object detecting sensor unit 100 is provided at one side of the bicycle 10, which is the rear of the driver, because the rear object detecting sensor unit 100 may recognize the movement of the driver as an approaching object.

후방물체감지센서부(100)는 접근하는 물체를 인식하여 거리를 감지하는 다양한 센서가 사용될 수 있으며, 초음파거리센서로 구비되는 것이 보다 바람직하다. 초음파(ultrasonics wave)는 인간이 들을 수 있는 가청 주파수(일반적으로 16Hz~20kHz의 범위)보다 높은 주파수를 갖는 음파로서, 일반적으로 20KHz 이상의 주파수를 갖는 음압을 의미한다. 초음파를 이용하여 거리를 측정하기 위해서는 초음파의 송신부와 수신부가 필요하며(송/수신부 병용 가능), 송신부가 송신한 초음파가 물체에 부딪혀 반사되어 수신부로 되돌아 오는 시간을 측정, 이를 통해 거리를 감지하게 된다.The rear object detecting sensor unit 100 may be various sensors that recognize an approaching object and sense the distance, and it is more preferable that the rear object detecting unit 100 includes an ultrasonic distance sensor. Ultrasonic waves are sound waves having a frequency higher than the human audible frequency (generally in the range of 16 Hz to 20 kHz), and generally means a sound pressure having a frequency of 20 KHz or more. In order to measure distances using ultrasonic waves, a transmitter and a receiver of ultrasonic waves are necessary (the transmitter / receiver can be used together), and the ultrasonic waves transmitted by the transmitter are reflected by the object and are reflected back to the receiver. do.

본 발명에서는 자전거에 부착된 하나 이상의 비상램프부(200)가 구비되는 것이 바람직하다. 일반적으로 운전자의 전방에 배치되는 전방비상램프부(210)와 후방에 배치되는 후방비상램프부(220)가 필요에 따라 1개가 구비될 수도 있으며, 동시에 모두 구비되는 것이 더욱 바람직하다.In the present invention, it is preferable that at least one emergency lamp unit 200 attached to the bicycle is provided. In general, the front emergency lamp unit 210 disposed at the front of the driver and the rear emergency lamp unit 220 disposed at the rear of the driver may be equipped with one or both of them.

후방물체감지센서(100)에 의해 물체가 감지되면 제어부(미도시)로 감지신호가 전송되고, 제어부는 비상램프부(200)에 신호를 전송하여, 비상램프부(200)에서 발광, 음향 등의 기능이 작동하게 된다.When an object is detected by the rear object detection sensor 100, a detection signal is transmitted to a control unit (not shown), and the control unit transmits a signal to the emergency lamp unit 200 so that the emergency lamp unit 200 emits light, The function of the function is activated.

도 2는 본 발명에 따른 자전거 후방감지시스템이 후방의 물체(자전거)를 감지하는 것을 나타내는 개념도이다.Fig. 2 is a conceptual diagram showing that the bicycle rear detection system according to the present invention detects a rear object (bicycle).

본 발명에 따른 자전거 후방감지시스템은 후방에서 물체가 접근하면 위험한 소정거리를 '위험거리(DD: Danger Distance)'로 정의하여 설정할 수 있다. 위험거리는 도로상태, 위험상태, 주행속도 등을 고려하여 설정될 수 있으며, 또한 상황에 따라 적절하게 변경될 수 있을 것이다.In the bicycle rear detection system according to the present invention, a dangerous predetermined distance may be defined as a 'danger distance (DD)' when an object approaches from the rear. The danger distance may be set in consideration of the road condition, the danger condition, the traveling speed, and the like, and may be appropriately changed depending on the situation.

본 발명에 따른 자전거 후방감지시스템은 위험거리(SD: safety Distance)를 도 2에 도시된 바와 같이, 보다 세분화하여 구분하는 것을 특징으로 한다.The bicycle rear detection system according to the present invention is characterized in that the safety distance (SD) is divided into subdivisions as shown in FIG.

본 발명에 따른 전방비상램프부(210)의 경우, 자전거와 접근물체와의 거리가 설정된 위험거리(DD) 이내로 접근되면, 제어부는 설정된 위험신호를 전송하여 전방비상램프부(210)에 설정된 위험표시가 작동되게 한다.In the case of the front emergency lamp unit 210 according to the present invention, when the distance between the bicycle and the approaching object is within the set danger distance DD, the control unit transmits a set danger signal, Let the display work.

구체적으로, 전방비상램프부(210)에는 방향표시부(211)가 구비되어, 접근하는 물체의 좌우방향이 발광 또는 점멸로 표시될 수 있다. 발광되는 색깔이나 점멸회수는 특정하게 제한되지 않고, 적절하게 설정되는 것이 바람직할 것이다. Specifically, the frontal emergency lamp unit 210 is provided with a direction indicator 211, so that the left-right direction of the approaching object can be indicated by flashing or flashing. The number of colors to be emitted or the number of blinks is not particularly limited, and is preferably set appropriately.

예로, 안전상태일때는 비발광 또는 녹색발광을 하다가, 위험거리이내로 감지되면, 적색발광 또는 점멸되도록 설정되는 것이 가능하다.For example, it can be set to emit no light or green light when it is in a safe state, and to emit red or blink when it is detected within a dangerous distance.

또한, 전방비상램프부(210)에는 음향알림부(212)가 구비되어 음향으로 알려질 수 있다. 음향으로 "위험거리접근" 등의 소리가 발생되도록 할 수도 있고, 지정된 음향이 발생되도록 할 수도 있을 것이다.In addition, the front emergency lamp unit 210 may be provided with an acoustic notification unit 212 and may be known as sound. It may be possible to cause a sound such as "danger distance approach" to sound, or to cause a specified sound to be generated.

나아가, 접근하는 물체가 자전거의 좌측 또는 우측에서 접근하는 지에 관한 정보를 제공하여 운전자가 위험상황에서 적절한 운전조치를 취하도록 할 수 있다. 이를 위해, 도 1에 도시된 바와 같이, 화살표 등의 방향표시부(211)를 구비하여, 그 방향표시부(211)가 발광 또는 점멸하게 하는 것이 가능하다. 물론 음향알림부(212)에서 방향을 소리로 발생시키는 것도 가능하다.Furthermore, it can provide information about whether the approaching object is approaching from the left or the right side of the bicycle, allowing the driver to take appropriate action in a hazardous situation. For this purpose, as shown in Fig. 1, it is possible to provide a direction indicator 211 such as an arrow to make the direction indicator 211 illuminate or blink. Of course, it is also possible to generate sound in the sound announcement unit 212 as a sound.

본 발명에 따른 후방비상램프부(220)의 경우, 자전거와 접근물체와의 거리가 설정된 위험거리 이내로 접근되면, 제어부는 설정된 위험신호를 전송하여 후방비상램프부(220)에 설정된 위험표시가 작동되도록 하는 것이 바람직하다.In the case of the rear emergency lamp unit 220 according to the present invention, when the distance between the bicycle and the approaching object approaches within a set danger distance, the control unit transmits a set danger signal, and the danger indicator set in the rear emergency lamp unit 220 is activated .

구체적으로, 접근하는 물체가 설정된 위험거리 이내로 접근된 경우, 설정된 접근단계에 따라 후방비상램프부(220)의 조도가 증가되도록 하는 것이 바람직하다. 예로, 접근하는 물체(자전거등)가 DD1 단계에서 DD2 단계로 더 가까워지면, 후방비상램프부의 조도(빛의 밝기)가 증가되어, 접근하는 물체에 위험상태에 대한 경고를 줄 수 있다. 또한, 예로 접근하는 물체(자전거등)가 DD3 단계에서 DD2 단계로 멀어지면, 조도가 감소되어 상호간의 거리가 멀어지고 있음을 알려주게 된다(도 2 참조).Specifically, when the approaching object is approaching within the set danger distance, it is preferable that the illuminance of the rear emergency lamp unit 220 is increased according to the set approaching step. For example, if an approaching object (such as a bicycle) gets closer to DD2 in step DD1, the illuminance of the rear emergency ramp (brightness of light) is increased to alert the approaching object of the danger. Also, if the approaching object (such as a bicycle) moves away from the DD3 stage to the DD2 stage, the illuminance is reduced and the distance between the objects is getting distant (see FIG. 2).

이러한 상호 거리의 증감을 음향알림부에서 음향의 증감으로 표시하는 것도 바람직하다.It is also preferable to display the increase or decrease of the mutual distances by increasing or decreasing the sound in the acoustic notification unit.

본 발명에 따른 비상램프부(200)는 제어부로부터 블루투스(Bluetooth) 방식 또는 지그비(ZigBee)방식 등의 근거리 무선통신방법에 의해 제어신호를 받는 것이m 자전거에 불필요한 부품을 최소화하는 측면 등에서 바람직하다. The emergency lamp unit 200 according to the present invention preferably receives a control signal from a control unit by a short-range wireless communication method such as a Bluetooth method or a ZigBee method, in order to minimize unnecessary parts for the motorcycle.
