Abstract
본 발명은 차량실내의 담배연기 등으로 인한 공기상태를 감지할 수 있는 연기센서를 개발·장착해서 실내의 공기상태를 검지한 후, 이에 따라 환기시스템을 자동적으로 구동시킬 수 있도록 된 차량용 환기시스템을 제공하고자 하는 것이다.The present invention is to develop and install a smoke sensor that can detect the air condition due to cigarette smoke in the vehicle room to detect the air condition in the room, accordingly the ventilation system for a vehicle that can automatically drive the ventilation system accordingly It is to provide.
이를 위해 본 발명은 밧데리전원(B+)과 제어부(7)의 입력측단자간에 설치되어 있는 이그니션스위치(8)와; 전원(Vcc)과 접지간에 설치되어 있고 전류가 인가될 경우 스스로 적외선을 방출할 수 있도록 된 적외선방출용 다이오드(1)와; 이 적외선방출용 다이오드(1)에 의해 방출되고 공기중의 연기나 오염기체로 인하여 산란된 적외선을 그 베이스에서 감지하는 포토트랜지스터(2) 및 그 비반전입력 단자가 상기 포토트랜지스터(2)의 이미터단자에 접속되어 있고, 그 반전입력단자가 저항간에 접속되어 상기 포토트랜지스터(2)로부터 출력된 소정의 전압을 증폭시키는 연산증폭기(3)로 이루어진 연기센서(4); 이 연기센서(4)의 연산증폭기(3)에 의해 증폭된 아날로그치의 전압을 디지탈형태의 데이터로 변환시키는 A/D컨버터(5)와 이 A/D컨버터(5)에 의해 변환된 소정의 디지탈데이터에 따라 소정의 제어치를 발생시키는 CPU(6)로 이루어진 제어부(7) 및 ; 이 제어부(7)에 의해 제어되고 상기 제어부(7)의 출력측 단자에 접속되어 있는 송풍기(9)를 구비하여 구성된 것을 특징으로 한다.To this end, the present invention includes an ignition switch (8) installed between the battery power source (B + ) and the input terminal of the control unit (7); An infrared emitting diode (1) installed between the power supply (Vcc) and the ground and capable of emitting infrared rays by itself when a current is applied; The phototransistor 2 and its non-inverting input terminal which emit infrared rays emitted by the infrared emitting diode 1 and scattered due to smoke or pollutant in the air at the base thereof are already formed in the phototransistor 2. A smoke sensor 4 which is connected to the terminal and whose inverting input terminal is connected between the resistors and comprises an operational amplifier 3 for amplifying a predetermined voltage output from the phototransistor 2; A / D converter 5 for converting the voltage of the analog value amplified by the operational amplifier 3 of the smoke sensor 4 into digital data and a predetermined digital converted by the A / D converter 5. A control unit 7 comprising a CPU 6 for generating a predetermined control value in accordance with the data; It is characterized by including the blower 9 which is controlled by this control part 7 and connected to the output side terminal of the said control part 7, It is characterized by the above-mentioned.
