일반적으로, 밀폐된 차안에서 혼자 수면을 취하고 있다거나 혹은 갓난아이나 자력으로 움직일수 없는 환자 등이 혼자서 장시간 동안 방치되어 있는 경우 차량내부의 온도가 지나치게 상승하게 되면 질식하는 경우가 발생하게 된다. 그러나, 종래의 자동차에는 이에 대한 방지 장치가 없어서 상기한 바와 같은 문제점을 예방할 수가 없었다.In general, when a person is sleeping alone in a closed car, or a newborn or a patient who cannot move by himself is left alone for a long time, the suffocation occurs when the temperature inside the vehicle becomes too high.

본 발명에 따른 일실시예를 참조로하여 본 발명의 작용 및 효과를 설명하기로 한다.With reference to one embodiment according to the present invention will be described the operation and effect of the present invention.
상기 도어 감지부(100)는 도어가 닫혀있으면 온되고, 도어가 열려있으면 오프되는 각각의 도어 스위치(앞우측도어, 앞좌측도어, 뒤우측도어, 뒤좌측도어)들로 구성된 도어 스위치부와 각각의 도어에 부착된 윈도우가 닫혀있으면 온되고, 윈도우가 열려있으면 오프되는 윈도우 스위치부로 구성되어 있고, 상기 스위치가 온되면 하이신호를, 상기 스위치가 오프되면 로우신호를 도어 신호(door.s)로 출력한다.The door detection unit 100 is a door switch unit composed of each door switch (front right door, front left door, rear right door, rear left door) that is turned on when the door is closed and turned off when the door is open. It consists of a window switch unit which is turned on when the window attached to the door of the door is closed, and is turned off when the window is opened, and a high signal when the switch is turned on and a low signal when the switch is turned off as a door signal (door.s). Output
상기 인체 감지부(200)는 차내부에 초전형 적외선 센서를 장착하여 인체에서 방출된 적외선이 감지되면, 이에 부합되는 전압을 인체감지신호(man.s)로 출력한다.The human body detecting unit 200 is equipped with a pyroelectric infrared sensor inside the vehicle, when the infrared light emitted from the human body is detected, and outputs a voltage corresponding to the human body as a human body detection signal (man.s).
상기 차량 속도 감지부(300)는 차량의 주행속도에 비례하는 속도펄스를 발생하는 속도센서(VSS : Vehicle Speed Sensor)를 이용하고, 발생된 속도펄스를 속도신호(speed.s)로 출력한다.The vehicle speed detecting unit 300 uses a vehicle speed sensor (VSS) for generating a speed pulse proportional to the traveling speed of the vehicle, and outputs the generated speed pulse as a speed signal (speed.s).
상기 마이컴(400)은 상기 도어신호(door.s)와 상기 인체감지신호(man.s) 및 상기 속도신호(speed.s)를 입력받아 도어와 윈도우가 모두 닫혀있고, 인체가 감지됨과 더불어, 차량이 정지하고 있는 것으로 판명되면, 소정의 기준시간을 카운트한 후, 윈도우 하강신호(down.s)를 출력한다.The microcomputer 400 receives the door signal (door.s), the human body detection signal (man.s) and the speed signal (speed.s), both the door and the window is closed, the human body is detected, If the vehicle is found to be stopped, the predetermined reference time is counted, and then the window down signal down.s is output.

이어서, 상기 실시예에서 이용된 초전형 적외선 센서와 속도센서를 도면을 참조하여 설명하기로 한다.Next, the pyroelectric infrared sensor and the speed sensor used in the above embodiment will be described with reference to the drawings.
초전형 적외선 센서는 초전효과를 이용하여 인체가 방사하는 적외선을 검출하게 되는데, 인체의 체온이 36∼37℃이므로 파장이 7∼10㎛에서 피크를 가진 원적외선이 방사되어 인체를 검출하는 것이다.The pyroelectric infrared sensor detects infrared rays emitted by the human body using the pyroelectric effect. Since the body temperature of the human body is 36 to 37 ° C., far infrared rays having a peak at a wavelength of 7 to 10 μm are radiated to detect the human body.
인체 감지 신호가 발생되는 과정을 초전형 적외선 센서의 단면도를 도시한 제2도를 참조하여 설명하면 다음과 같다.The process of generating the human body detection signal will be described with reference to FIG. 2 which shows a cross-sectional view of the pyroelectric infrared sensor.
여러 파장의 적외선이 센서에 입사되면 센서 윈도우부분(211)의 광학 필터에 의해 인체의 적외선파장(7∼10㎛)만 통과된다. 통과된 적외선은 열흡수막(212)으로 입사되어 적외선이 열로 변환되고, 상기 열흡수막(212)과 접해있는 감지소자(213)의 표면온도가 상승하여 초전효과에의해 표면전하가 발생된다.When infrared rays of various wavelengths are incident on the sensor, only the infrared wavelength (7 to 10 μm) of the human body passes through the optical filter of the sensor window portion 211. The infrared rays passed through are incident on the heat absorption film 212, and the infrared rays are converted into heat, and the surface temperature of the sensing element 213 in contact with the heat absorption film 212 increases to generate surface charges by the pyroelectric effect.
상기 발생된 표면전하가 전계효과 트랜지스터(214)에 의해 전압 증폭되며, 임피던스가 변환된다. 이때 전계효과 트랜지스터(214)를 구동시키기위한 구동전압은 드레인 단자(215)를 통해 공급되고, 상기 증폭된 전압신호와 외부에 접속된 소스 단자(216)와 어스 단자(217)간의 바이어스 전압이 중첩되어 인체감지신호(man.s)로서 출력되어 상기 마이컴(400)으로 입력된다.The generated surface charge is voltage amplified by the field effect transistor 214, and the impedance is converted. In this case, a driving voltage for driving the field effect transistor 214 is supplied through the drain terminal 215, and the amplified voltage signal overlaps with a bias voltage between the source terminal 216 and the earth terminal 217 connected to the outside. The body is output as a human body detection signal (man.s) is input to the microcomputer 400.
상기에 기술한 초전효과에 대해 설명하자면, 감지소자(213)에 고전압을 걸어서 분주시키면 소자표면에 생긴 양전하와 음전하는 공기 속의 반대전하를 지닌 부유이온과 결합하여 전기적으로 중화되는데, 만약 소자표면의 온도가 변화하면 이에 따라 감지소자(213)의 극성 크기가 변화하게 되어서 감지소자(213)의 전기적 평형상태가 무너지고 결합 할 상대가 없는 전하가 발생하게 되는 것이다.In the above description of the pyroelectric effect, when the high voltage is applied to the sensing element 213, the positive and negative charges generated on the surface of the device are electrically neutralized by combining with floating ions having opposite charges in the air. When the temperature changes, the polarity of the sensing element 213 is changed accordingly, thereby causing the electrical equilibrium state of the sensing element 213 to collapse, and a charge having no counterpart to generate is generated.
이와 같이 온도변화에 따라 전하가 발생하는 현상을 초전효과라고 한다.As such, a phenomenon in which charge occurs due to temperature change is called a pyroelectric effect.
이어서, 제3도는 본 발명에 따른 실시예에서 이용된 속도센서를 도시한 회로도로서, 차속을 검출하는 속도신호(speed.s)가 발생되는 과정을 살펴보면 다음과 같다.Next, FIG. 3 is a circuit diagram illustrating a speed sensor used in an embodiment according to the present invention. The process of generating a speed signal (speed.s) for detecting a vehicle speed is as follows.
속도센서(VSS)는 발광다이오드(LED)와 포토트랜지스터(Ph.T)가 조합되어 일체형으로 된 포토인터럽터(Ph.I)와 속도계 케이블(도시하지 않음)에 의해 구동되는 차광판으로 구성되는데, 상기 차광판에는 몇장의 날개가 붙어 있다.The speed sensor VSS is composed of a light blocking plate driven by a photointerrupter Ph.I and a speedometer cable (not shown) which are integrated by combining a light emitting diode (LED) and a phototransistor (Ph.T). There are several wings on the light shield plate.
차량이 움직이면 속도계 케이블이 회전하게 되고 이에 따라 차광판이 회전하여 발광 다이오드(LED)와 포토 트랜지스터사이에 차광판이 있는 경우와 차광판이 없는 경우가 발생된다.When the vehicle moves, the speedometer cable rotates. As a result, the light blocking plate rotates, and thus there is a case where there is a light blocking plate between the light emitting diodes (LEDs) and the phototransistor and there is no light blocking plate.
우선, 차광판이 없는 경우에는 포토 트랜지스터(Ph.T)에 발광다이오드(LED)의 빛이 닿게 되어 포토 트랜지스터(Ph.T)가 온 되고, 트랜지스터(Q1)의 베이스 전류가 흘러 트랜지스터(Q1)는 온 되어 출력단자의 전위가 OV가 된다.First, when there is no light blocking plate, the light of the light emitting diode LED comes into contact with the phototransistor Ph.T, the phototransistor Ph.T is turned on, and the base current of the transistor Q1 flows to the transistor Q1. On, the potential of the output terminal becomes OV.
다음에 차광판이 있는 경우에는 지금까지 포토트랜지스터(Ph.T)에 비추고 있던 발광 다이오드(LED)의 빛이 차단되기 때문에, 포토 트랜지스터(Ph.T)는 오프 되고 트랜지스터(Q1)의 베이스전류가 차단되어 트랜지스터(Q1)는 오프 된다. 따라서, 출력단자의 전위가 전원전위(Vcc)까지 상승한다.When there is a light blocking plate next, since the light of the light emitting diode LED which has been reflected on the phototransistor Ph.T is cut off, the phototransistor Ph.T is turned off and the base current of the transistor Q1 is cut off. The transistor Q1 is turned off. Therefore, the potential of the output terminal rises to the power supply potential Vcc.
이와 같이 출력단자 전위변화가 펄스 신호가 되어 속도신호(speed.s)로서 상기 마이컴(400)으로 보내져 차속이 검출되는 것이다.In this way, the output terminal potential change becomes a pulse signal and is sent to the microcomputer 400 as a speed signal (speed.s) to detect the vehicle speed.
상기와 같은 동작을 하는 초전형 적외선 센서와 속도센서(VSS)를 이용하여 구성된 본 발명에 따른 윈도우 자동 하강 장치의 실시예는, 상기 도어 스위치와 윈도우 스위치가 모두 오프된 상태를 감지한 도어 신호(door.s)와 상기 초전형 적외선 센서에 의해 인체에서 방출된 적외선을 감지한 인체 감지 신호(man.s) 및 상기 속도센서(VSS)에 의해 차량이 정지하고 있음을 OV의 속도신호(zero.s)로 입력받은 상기 마이컴(400)은 타이머를 이용해서 소정의 기준시간이 경과된 후, 상기 윈도우 하강신호(down.s)를 출력하여 윈도우 구동 스위치를 턴온 시키고, 이에 따라 배터리 전원이 윈도우 모터(50)를 회전시켜서 윈도우를 하강시키므로써 밀폐된 차안에 공기가 유입되는 것이다.Embodiment of the automatic window lowering device according to the present invention configured using the pyroelectric infrared sensor and the speed sensor (VSS) to operate as described above, the door signal (S) detecting the state that the door switch and the window switch are both off ( door.s) and the human body detection signal (man.s) detecting the infrared rays emitted from the human body by the pyroelectric infrared sensor and the speed sensor (VSS) that the vehicle is stopped by the speed signal (zero. The microcomputer 400 received through s) turns on the window drive switch by outputting the window down signal down.s after a predetermined reference time has elapsed by using a timer. By rotating the 50, the window is lowered so that air is introduced into the sealed car.
이상에서 살펴본 바와 같이, 본 발명에 따르면 자동차의 내부에 초전형 적외선 센서를 장착하여 밀폐된 차안에 사람이 장시간 방치되어 있을 때에는 인체에서 방출된 적외선을 센서가 감지하여 인체감지신호를 마이컴에 보내주어 마이컴이 윈도우를 제어할 수 있도록하여 승객의 질식 사고등을 예방할 수 있는 효과가 있다.As described above, according to the present invention, when a person is left in a closed car for a long time by mounting a pyroelectric infrared sensor inside the vehicle, the sensor detects infrared rays emitted from the human body and sends a human body detection signal to the microcomputer. By allowing the microcomputer to control the window, it is possible to prevent passengers from choking.
