The storage unit 100 stores the pressure value measured at the time of switching the detection alarm mode as the reference pressure value.

경보스위치(200)는 스위치가 온(on) 되면, 감지경보모드전환신호를 출력한다.The alarm switch 200 outputs a detection alarm mode switching signal when the switch is turned on.

보다 자세하게는, 운전자가 콘트롤러를 이용하여 스위치가 온(on)/오프(off) 되도록 원격 제어할 수 있거나 또는 운전자가 시동을 끄고 문을 잠갔을 때, 도어의 잠김 여부를 감지하는 도어락감지수단에 의해 스위치가 온(on)이 되도록 하여 감지경보모드로 바로 전환할 수가 있다.More specifically, the driver may remotely control the switch to be turned on or off using the controller, or the door lock detecting means for detecting whether the door is locked when the driver turns off the engine and locks the door. This allows the switch to be turned on so that it can be switched directly to the sensing alarm mode.

검출부(300)는 외부로부터 입력되는 검출제어신호에 응하여 차량 실내의 공기압을 검출한다.The detection unit 300 detects the air pressure in the vehicle interior in response to a detection control signal input from the outside.

제어부(400)는 감지경보프로그램 정보를 관리하고, 감지경보모드로 전환시 상기 저장부(100)에 저장된 프로그램에 따른 제어를 수행한다. 상기 제어부(400)는 다음과 같은 기능을 한다.The control unit 400 manages detection alarm program information, and performs control according to a program stored in the storage unit 100 when switching to the detection alarm mode. The control unit 400 functions as follows.

첫째, 상기 경보스위치(200)를 통해 감지경보모드전환신호가 입력되면 현재 모드를 감지경보모드로 전환시킨다.First, when the detection alarm mode switching signal is input through the alarm switch 200, the current mode is switched to the detection alarm mode.

둘째, 상기 검출부(300)로 검출제어신호를 출력하여 차량의 실내 공기압을 측정할 수 있도록 제어한다.Second, it outputs a detection control signal to the detector 300 to control the indoor air pressure of the vehicle.

셋째, 측정된 차량의 실내공기압을 상기 저장부(100)에 기준압력값으로 저장되도록 제어한다.Third, the measured indoor air pressure of the vehicle is controlled to be stored in the storage unit 100 as a reference pressure value.

다섯째, 상기 검출부(300)로부터 입력되는 차량의 실내공기압을 상기 기준압력값과 비교하여 허용된 오차범위 이내인가를 판단하여, 오차범위를 벗어나면 경보발생제어신호를 출력하고, 오차범위 안에 있으면 측정된 실내공기압을 새로운 기준압력값으로 갱신한다.Fifth, it is determined whether the indoor air pressure of the vehicle input from the detection unit 300 is within the allowable error range by comparing with the reference pressure value, and if it is out of the error range, an alarm generation control signal is output, and if it is within the error range, the measurement is performed. The revised indoor air pressure to the new reference pressure value.

여기서, 경보발생제어신호를 출력할 때, 제어부(400)는 차량의 혼(Horn)을 구동시키기 위한 신호를 출력하거나 또는 차량의 비상램프의 점멸을 동작시키기 위한 신호를 출력한다. 이 경우에 상기 제어부(400)는 경적음의 크기 조절 및 비상램프의 점멸 주기와 점멸 지속시간을 제어할 수도 있다.Here, when outputting the alarm generation control signal, the control unit 400 outputs a signal for driving the horn of the vehicle or a signal for operating the flashing of the emergency lamp of the vehicle. In this case, the controller 400 may control the volume of the horn and control the flashing period and the flashing duration of the emergency lamp.

경보발생부(500)는 상기 제어부(400)의 경보발생제어신호에 응하여 경보신호 를 출력한다. 이때, 경보발생부(500)는 차량의 혼(Horn) 또는 비상램프를 작동시킨다.The alarm generation unit 500 outputs an alarm signal in response to the alarm generation control signal of the control unit 400. At this time, the alarm generating unit 500 operates the horn or emergency lamp of the vehicle.

이와 같이 구성된 본 발명은 침입자가 차량의 유리를 파손해서 침입하거나 또는 차량의 문을 따고 침입하는 경우에, 외부공기가 차량 내부로 유입되면서 공기의 갑작스런 변화를 상기 검출부(300)가 즉각 감지하여 차량의 경적을 울리거나 비상램프를 점멸시켜 도난경보를 주위로 알리게 함으로써, 차량 도난을 막을 수 있게 된다.According to the present invention configured as described above, in case an intruder breaks through the glass of the vehicle or intrudes the door of the vehicle, the detection unit 300 immediately detects a sudden change of air while the outside air flows into the vehicle. You can prevent theft of your vehicle by sounding the horn or flashing the emergency lamp to alert theft alarms.

한편, 본 발명에 따른 경보 장치는 여름철 날씨로 인해 차량 내부온도가 급격하게 상승할 경우에 온도변화에 따라 압력차가 발생하게 되는데, 이러한 압력차에 의한 오작동을 방지하기 위해서 온도변화를 감지하는 온도센서와, 내부온도가 상승한 만큼 기준압력값을 보상해주는 압력보정수단을 더 구비할 수도 있다.On the other hand, the alarm device according to the present invention is a pressure difference occurs in accordance with the temperature change when the temperature inside the vehicle is rapidly increased due to the weather in summer, the temperature sensor for detecting the temperature change in order to prevent malfunction due to such a pressure difference And, it may further include a pressure correction means for compensating the reference pressure value as the internal temperature rises.

이에 따라, 내부온도가 상승한 만큼 차량 실내압을 보상하여 줌으로써, 압력차에 의한 오작동에 대해서 효과적으로 대응할 수 있게 된다. Accordingly, by compensating the vehicle interior pressure as the internal temperature rises, it is possible to effectively cope with a malfunction caused by the pressure difference.

도 2는 본 발명에 따른 차량 실내압 변화 감지 경보 장치의 순서도이다.2 is a flow chart of the vehicle interior pressure change detection alarm apparatus according to the present invention.

도 2를 참조하면, 본 발명에 따른 차량 실내압 변화 감지 경보 장치의 작동과정을 설명한다.Referring to Figure 2, it will be described the operation of the vehicle interior pressure change detection alarm apparatus according to the present invention.

본 발명의 감지경보모드 개시는 경보스위치(200)의 조작에 따라 감지경보모드가 설정 또는 해제가 된다.(S100)In the detection alarm mode start of the present invention, the detection alarm mode is set or released according to the operation of the alarm switch 200. (S100)

먼저, 감지경보모드가 개시되면, 제어부(400)는 검출부(300)로 검출제어신호 를 출력하여 차량 실내압을 측정하도록 하고, 측정된 차량의 실내 공기압을 상기 저장부에 기준압력값으로 저장되도록 제어한다.(S110)First, when the detection alarm mode is started, the control unit 400 outputs a detection control signal to the detection unit 300 to measure the vehicle interior pressure, and stores the measured indoor air pressure of the vehicle as a reference pressure value in the storage unit. Control. (S110)

이어서, 제어부(400)는 미리 설정된 시간만큼 시간을 카운팅한다.(S120) 설정시간이 경과되면, 제어부(400)는 다시 검출부(300)로 검출제어신호를 보낸다.(S130) Subsequently, the controller 400 counts the time by a predetermined time. (S120) When the set time has elapsed, the controller 400 sends a detection control signal to the detector 300 again (S130).

검출부(300)는 제어부(400)의 신호에 따라서 차량의 실내 공기압을 측정한다.(S140) The detector 300 measures the indoor air pressure of the vehicle according to the signal of the controller 400 (S140).

제어부(400)는 상기 검출부(300)에 의해 측정된 실내 공기압을 저장부(100)에 저장된 기준압력값과 비교한다. 측정된 실내공기압이 허용오차범위 내에 있는지를 판단하여 허용오차범위 내에 벗어나면 S160 단계로, 측정된 실내 공기압이 허용오차범위 안에 있다고 판단되면, 제어부(400)는 측정된 실내공기압을 새로운 기준압력값으로 갱신한 후, 상기 S120 단계로 피드백하여, 주기적으로 공기압을 측정하도록 한다. (S150)The controller 400 compares the indoor air pressure measured by the detector 300 with a reference pressure value stored in the storage 100. If it is determined that the measured indoor air pressure is within the tolerance range and is out of the tolerance range, in step S160, if it is determined that the measured indoor air pressure is within the tolerance range, the controller 400 determines the measured indoor air pressure as a new reference pressure value. After updating to, to feed back to step S120, to periodically measure the air pressure. (S150)

측정된 실내 공기압이 허용오차범위 내에 벗어난다고 판단되면, 제어부(400)는 경보발생제어신호를 출력하여 경보발생부(500)를 작동시킨다. 상기 경보발생부(500)는 차량의 혼을 구동시키거나 또는 차량의 비상등을 점멸시킨다.(S160)If it is determined that the measured indoor air pressure is out of the tolerance range, the controller 400 outputs an alarm generation control signal to operate the alarm generation unit 500. The alarm generator 500 drives the horn of the vehicle or flashes the emergency light of the vehicle.

지금까지 기술한 바와 같이, 본 발명의 차량 실내압 변화 감지 경보 장치는 차량의 문을 따고 침입하는 경우 또는 차량의 문을 부수고 침입하는 경우에 외부공기가 차량 내부로 유입되는 것을 즉각 감지하여 경보를 발생시켜 차량 도난을 방지 할 수 있는 장점이 있다.As described above, the vehicle interior pressure change detection device of the present invention immediately detects the inflow of external air into the vehicle when the vehicle is invaded by the door or the vehicle is broken through the door. There is an advantage to prevent theft of the vehicle.
