Abstract

본 발명은 타이어 압력측정 경보장치에 관한 것으로서, 특히 자동차 운행중 타이어 내부 공기압력을 측정하여 경보를 알리는 장치와 이에 적합한 제어방법에 관한 것이다.The present invention relates to a tire pressure measurement alarm apparatus, and more particularly, to a device for informing an alarm by measuring air pressure inside a tire during operation of a vehicle and a control method suitable for the apparatus.

본 발명에 따라 타이어 압력측정 경보장치는 소정의 시간마다 주행중인 자동차의 각 타이어 공기압을 측정하여 아날로그신호로 출력하는 공기압측정부; 상기 측정부에서 측정된 공기압의 아날로그신호를 디지털신호로 변환하는 신호변환부; 상기 신호변환부에서 출력된 디지털신호의 공기압력값의 평균치를 산출하고 소정의 기준값과 비교하여 공기압의 이상유무 신호를 출력하는 제어부; 및 상기 제어부에서 출력된 공기압의 이상유무 신호에 따라 경보를 알리는 경보부를 포함함을 특징으로 한다.According to the present invention, there is provided a tire pressure measurement alarm apparatus comprising: an air pressure measurement unit for measuring tire pressure of each tire of a vehicle during a predetermined time and outputting the measured tire pressure as an analog signal; A signal converting unit for converting an analog signal of the air pressure measured by the measuring unit into a digital signal; A control unit for calculating an average value of air pressure values of the digital signal output from the signal converting unit and comparing the air pressure values with a predetermined reference value to output an air pressure abnormality signal; And an alarm unit for informing an alarm according to an abnormality signal of the air pressure output from the control unit.

본 발명에 의해 자동차 주행중에 타이어의 공기압을 소정의 시간마다 측정하여 기준치의 범위를 벗어난 경우에 경보를 통하여 운전자에게 알림으로써 운전자가 안전 운행을 할 수 있도록 한다.According to the present invention, when the air pressure of the tire is measured at predetermined time intervals during driving of the vehicle, the driver is informed to the driver through the alarm when the range of the reference value is out of range.
