Description
본 고안은 차량용 가스감지기에 관한 것이다.The present invention relates to a gas detector for a vehicle.
일반적으로 LPG 사용승합차, 택시 등과 같은 차량은 엔진 구동을 위한 연료로서 LPG 가스를 사용하고 있고, 이는 연료 비용면에서 경제적이다. 그러나, 이러한 차량에 있어서의 가스는 가스통과 호스와의 연결부위 또는 호스의 부식, 엔진내부 배관 및 가스장치 등으로 부터 누설되는 것이 다반사고, 이러한 누설된 가스는 완전 밀폐되지 않은 차량 내부로 스며들어 인체에 유해한 가스가 차량내부에 장시간 앉아 있는 운전자에게 악영향을 미친다. 따라서, 운전자는 무색무취의 가스에 노출되어 심하면 가스중독에 의한 사망을 가져올 수 있고, 운전중에는 운전에 큰 장해를 줄 수 있는 것이어서 안전사고 발생이 크게 우려되고 있는 실정이다.In general, vehicles such as LPG vans and taxis use LPG gas as fuel for driving an engine, which is economical in terms of fuel cost. However, the gas in such a vehicle is often leaked from the connection between the gas cylinder and the hose or from the corrosion of the hose, the internal pipes of the engine and the gas system, and such leaked gas is permeated into the vehicle that is not completely sealed. Gas harmful to the human body adversely affects the driver who sits in the vehicle for a long time. Therefore, the driver is exposed to colorless and odorless gas, which can cause death due to gas poisoning, and may cause serious obstacles during driving.
본 고안은 차량 내부로 스며든 가스를 감지하여 운전자에게 알려 줄 수 있게 함으로써, 유해가스로부터 운전자를 보호하고, 안전사고 유발을 미연에 방지함을 목적으로 한다.The present invention aims to protect the driver from harmful gases and to prevent the occurrence of safety accidents by detecting the gas permeated into the vehicle and informing the driver.
본 고안은 LPG 사용 승합차, 택시 등과 같은 차량 트렁크에 설치된 LPG 가스통, 호스, 엔진내부 배관 및 가스장치로부터의 누설되는 가스가 차량 내부에 인입될 시 이를 확인할 수 있도록 표시 또는 경보하여 가스로 부터 운전자를 보호하도록 함을 기술적 과제로 삼는다.The present invention displays or alerts the driver when gas leaks from LPG gas cylinders, hoses, internal engine pipes and gas equipment installed in the trunk of a vehicle such as an LPG-enabled van or taxi. Protecting is a technical challenge.
상기 과제를 달성하기 위한 본 고안은 가스 감지기 본체를 차량 내부의 시거 잭에 삽착하여 전원을 공급받아 차량내부에 스며든 가스를 감지하도록 함을 특징으로 한다. 상기에서 가스 감지기 본체는 차량내부의 가스를 감지하는 가스센서부와, 가스센서로 부터 감지된 신호를 증폭시키는 증폭부와, 증폭된 신호를 기준전압과 비교하는 비교회로부와, 기준전압이상의 출력 신호가 발생시 구동하는 경고 및 표시회로부로 구성된다.The present invention for achieving the above object is characterized in that the gas detector body is inserted into the cigar jack in the vehicle to detect the gas permeated into the vehicle by receiving power. The gas detector main body includes a gas sensor unit for detecting gas in the vehicle, an amplifier unit for amplifying a signal detected from the gas sensor, a comparison circuit unit for comparing the amplified signal with a reference voltage, and an output signal above the reference voltage. It consists of a warning and display circuit unit to drive when the occurrence.

본 고안은 가스 감지기 본체(10)를 차량 내부의 시거 잭(미도시)에 삽착하여 전원을 공급받아 차량내부에 스며든 가스를 감지하도록 하되, 가스 감지기 본체 (10)는 차량내부의 가스를 감지하는 가스센서부(1)와, 상기 가스센서부(1)내의 가스센서로 부터 감지된 신호를 증폭시키는 증폭부(2)와, 증폭된 신호를 기준전압과 비교하는 비교회로부(3)와, 기준전압이상의 출력 신호가 발생시 구동하는 경고 및 표시회로부(4)로 구성된다. 상기에서, 증폭부(2)는 오피앰프로 구성하며, 비교회로부(3)는 비교기로서 기준전압과 입력신호를 비교하는 것으로, 원칩 마이컴을 이용하여도 무방하다. 즉, 멀티플랙서와, 상기 멀티플랙서의 신호를 디지털 신호로 변환하는 A/D컨버터와, 램 및 롬과 연결된 중앙처리장치의 프로그램에 의해 디지털 신호를 I/O포트를 통해 출력케 하는 마이컴을 이용하여 경고 및 표시회로부(4)를 구동하게 할 수 있다. 상기 경고 및 표시회로부(4)는 스위칭 트랜지스터, LED 및 버저로 구성한다.The present invention inserts the gas detector main body 10 into a cigar jack (not shown) inside the vehicle to detect the gas permeated into the vehicle by receiving power, but the gas detector main body 10 detects the gas inside the vehicle. A gas sensor unit 1, an amplification unit 2 for amplifying a signal sensed by the gas sensor in the gas sensor unit 1, a comparison circuit unit 3 for comparing the amplified signal with a reference voltage, It consists of a warning and display circuit section 4 which drives when an output signal above the reference voltage is generated. In the above description, the amplifier 2 comprises an op amp, and the comparison circuit 3 compares the reference voltage and the input signal as a comparator, and may use a one-chip microcomputer. In other words, the multiplexer, an A / D converter that converts the signal of the multiplexer into a digital signal, and a microcomputer that outputs the digital signal through the I / O port by a program of a central processing unit connected to RAM and ROM. It is possible to drive the warning and display circuit unit 4 by using. The warning and display circuit section 4 is composed of a switching transistor, an LED and a buzzer.
이와같은 구성의 본 고안은 차량 내부의 시거 잭에 가스 감지기 본체(10)를 꽂은 후 차량 내부로 스며든 가스를 감지하여 경고 및 표시케 한다. 즉, 가스가 가스 센서부(1)에 의해 감지되면 이 신호를 증폭부(2)의 오피앰프로서 증폭 시키고, 증폭된 신호는 기준전압과 비교회로부(3)의 비교기에 의해 비교되어 기준전압 이상일 경우에는 이 출력신호가 경고 및 표시회로부(4)의 트랜지스터를 도통 시키고, 이에따라 LED 및 버저가 표시 및 구동되어 운전자에게 이를 알려 주게 되어 차량내부에 가스의 진입을 손쉽게 알 수 있게된다.The present invention of such a configuration allows the gas detector body 10 to be inserted into the cigar jack in the vehicle, and then detects the gas that has penetrated into the vehicle to warn and display. That is, when gas is detected by the gas sensor unit 1, this signal is amplified as an op amp of the amplifier 2, and the amplified signal is compared by the comparator of the reference voltage unit and the comparison circuit unit 3 to be equal to or greater than the reference voltage. In this case, the output signal conducts the transistor of the warning and display circuit unit 4, and accordingly, the LED and the buzzer are displayed and driven to inform the driver so that the gas can be easily recognized in the vehicle.
본 고안은 차량내부에 진입된 가스를 운전자가 알 수 있도록 표시 또는 경보케 함으로써, 인체에 유해한 가스로 부터의 피해를 미연에 방지하게 되고, 특히 운전자를 가스중독으로 부터 보호할 수 있어 가스로 인한 안전사고 유발을 방지 및 가스누설에 의한 폭발사고를 방지할 수 있는 효과를 가진다.The present invention prevents damage from gas harmful to the human body by displaying or alarming gas entered into the vehicle so that the driver can know, and in particular, protects the driver from gas poisoning. It has the effect of preventing the occurrence of safety accidents and preventing explosion accidents due to gas leakage.
