Abstract
Description
[도 3], [도 5], [도 6]에 예시한 것과 같이 종래 기술을 이용하는 경우 반사 특성이 명확히 구분 되는 무반사 바닥면에 반사체를 사용하는 경우와 반사하는 바닥면에 무반사 특성의 반사체로 구성되는 경로에 대해서는 잘 동작하나, 반사 특성이 유사한 바닥면(흰색 프린터용 종이)에 반사체(무반사 써스판 또는 유리면 써스판)를 경로 장치로 사용하는 경우 종래 기술을 사용하는 경우 바닥면과 반사체에서 반사되는 빛의 세기를 분리할 수 없기 때문에 적외선 센서의 동작 거리가 짧아지며, 동작 각도를 향상시키기 위한 방법이 어렵게 된다. As shown in Fig. 3, Fig. 5, and Fig. 6, in the case of using the prior art, a reflector is used for the antireflection bottom surface where the reflection characteristics are clearly distinguished, and as a reflector having antireflection property on the bottom surface that reflects. It works well for the path that is constructed, but when the reflector (anti-reflective or glass surface plate) is used as the path device on the bottom surface (paper for white printers) with similar reflection characteristics, the bottom surface and the reflector in the prior art are used. Since the intensity of the reflected light cannot be separated, the operating distance of the infrared sensor is shortened, and a method for improving the operating angle becomes difficult.
유사한 반사 특성을 갖는 바닥면과 반사체에서 반사되는 적외선을 구분할 수 있도록 적외선 센서의 발광부와 수광부의 배치 및 광경로 장치를 추가하여 무인반송차의 경로를 에러 없이 인식할 수 있도록 하는 반사특성이 유사한 반사체의 인식을 위한 적외선 센서를 제공함을 목적으로 한다. Similarly, the reflection and the light-receiving part of the infrared sensor are added and the light path device is added to distinguish the infrared rays reflected from the reflector and the bottom surface having similar reflection characteristics. An object of the present invention is to provide an infrared sensor for recognizing a reflector.
반사체(거울반사)와 바닥면(난반사)의 반사특성이 유사하지만 반사각도 및 빛의 반사량에 차이가 있다는 것을 이용하여 포토 다이오드(40)에 적외선 발광 다이오드(20)의 높이보다 높게 빛을 흡수하는 재질로 속이 빈 막대(예, 검정색 아크릴 재질의 속이 빈 원통형 막대)를 세우게 된다. 이렇게 세워진 광경로장치(30)를 통해 입사되는 광은 거울반사 특성을 갖는 반사체로부터 반사되는 광이 대부분이며, 바닥면에서 반사된 빛은 광경로장치(30)에 입사되지 못하고 외부로 반사하게 되어 반사체와 바닥면을 쉽게 구분할 수 있게 된다. 또한 적외선 센서의 인식 각도를 향상시키기 위해 도 2b와 같이 한 개의 포토 다이오드(40)에 센서의 인식 각도를 향상시키기 위한 방향으로 여러 개의 적외선 발광 다이오드(20)를 배치할 수 있으며, 도 2a는 전후 방향의 인식 각도를 향상시키기 위해 적외선 발광 다이오드(20)를 배치한 센서의 구성 예이다. Although the reflection characteristics of the reflector (mirror reflection) and the bottom surface (reflective reflection) are similar, but the difference in the reflection angle and the amount of reflection of light is used, the photodiode 40 absorbs light higher than the height of the infrared light emitting diode 20. The material will stand a hollow bar (e.g. a hollow cylindrical bar made of black acrylic). The light incident through the optical path device 30 erected in this way is most of the light reflected from the reflector having a mirror reflection characteristic, and the light reflected from the bottom surface does not enter the optical path device 30 and reflects to the outside. The reflector and the bottom can be easily distinguished. In addition, in order to improve the recognition angle of the infrared sensor, as shown in FIG. 2B, a plurality of infrared light emitting diodes 20 may be disposed in one photodiode 40 in a direction for improving the recognition angle of the sensor. It is a structural example of the sensor which arrange | positioned the infrared light emitting diode 20 in order to improve the recognition angle of a direction.
종래의 기술로는 반사체(거울반사)와 바닥면(난반사)으로 구성된 무인반송차의 경로 장치에서 인식 거리 20mm, 인식 각도 5로 진동이 많은 경우에 사용이 어려운 문제점이 있다. 본 고안에서 예시한 도 1, 도 2a의 센서 구성으로는 인식 거리 30mm, 인식 각도 10로 진동이 많은 열악한 환경에서 보다 안정적으로 경로의 인식이 가능하다. Conventional technology has a problem in that it is difficult to use when there is a lot of vibration at a recognition distance of 20 mm and a recognition angle of 5 in a path device of an unmanned vehicle consisting of a reflector (mirror reflection) and a bottom surface (reflection reflection). In the sensor configuration of FIGS. 1 and 2A illustrated in the present invention, a path can be more stably recognized in a harsh environment having a lot of vibrations at a recognition distance of 30 mm and a recognition angle of 10.
