음주측정기 교정시스템{calibration system for Breath Alcohol Analyzers}Calibration system for breath alcohol analyzers

본 발명은 음주측정기가 정확히 동작하는지를 검증하는 음주측정기 교정시스템에 관한 것이다.The present invention relates to a breathalyzer calibration system for verifying that the breathalyzer works correctly.

음주측정기는 운전자의 음주량을 측정하기 위한 장치로서 운전자의 음주량에 따라 운전자는 사법 처리되기 때문에 음주측정기의 신뢰도가 담보되어야한다.Breathalyzer is a device for measuring the amount of driver's drinking. Since the driver is judicially processed according to the driver's drinking amount, the reliability of the breathalyzer should be guaranteed.

따라서 음주측정기는 주기적으로 정확히 동작하는 지를 테스트하는 교정작업이 이루어져야 하고, 통상적인 음주측정기의 교정작업은 교정자가 음주측정기를 알콜 표준가스통에 연결하여 측정되는 알콜농도를 판독하여 이루어지고 있으나, 이러한 교정작업은 교정자가 한 번에 하나씩의 음주측정기만을 테스트할 수 있기 때문에 많은 시간이 소요되고, 교정작업의 정밀성이 떨어지는 문제점이 있었다.Therefore, the breathalyzer should be calibrated periodically to test the correct operation, and the calibration of the conventional breathalyzer is performed by reading the alcohol concentration measured by the calibrator by connecting the breathalyzer to the alcohol standard gas cylinder. The work takes a lot of time because the calibrator can test only one breathalyzer at a time, there was a problem that the precision of the calibration work is poor.

또한, 종래의 교정작업시에 음주측정기에 주입되는 알콜 표준가스가 사람의 날숨 온도(34℃)보다 떨어지기 때문에 정확한 교정이 이루어질 수 없었다.In addition, since the alcohol standard gas injected into the breathalyzer in the conventional calibration operation is lower than the human exhalation temperature (34 ℃) could not be accurate calibration.

또한, 종래의 교정작업시에는 교정자가 표준가스통에 연결된 정유량밸브를 조작하여 음주측정기에 표준가스를 주입시켰기 때문에 정확히 주입되는 표준가스량을 제어하기가 곤란하였다.In addition, in the conventional calibration operation, since the calibrator manipulated the constant flow valve connected to the standard gas cylinder to inject the standard gas into the breathalyzer, it was difficult to accurately control the standard gas amount injected.

또한, 종래의 교정방법으로는 교정장소내에 표준가스가 배출되어 머물기 때문에 교정자는 교정시에 알콜 표준가스를 흡입하는 문제점이 있어 건강상의 문제를 야기시킨다.In addition, in the conventional calibration method, since the standard gas is discharged and stays in the calibration site, the calibrator has a problem of inhaling the alcohol standard gas during calibration, causing health problems.

본 발명은 이러한 문제점을 해결하기 위한 것으로, 본 발명의 해결과제는 다수개의 음주측정기를 동시에 교정할 수 있도록 하면서도 정확히 교정될 수 있도록 하는 음주측정기 교정시스템을 제공하기 위한 것이다.
