Abstract

The present invention relates to a method for correcting a sensor with respect to the concentration of air in a non-aspirated drunkometer, and a non-aspirated drunkometer applied with the same. According to the present invention, a detecting reference value of a sensor is corrected by the concentration of external air and thus, a process of precisely correcting the sensor can be automatically or manually performed at all times or at an appropriate time. Therefore, the non-aspirated drunkometer is always corrected without a user or a professional correcting institution, thereby always maintaining the highest sensitivity and accuracy, and securing the convenience of use.

Description

자동 교정 기능을 탑재한 비호기식 음주감지기 및 방법 {Non-breath DUI tester with automatic calibration and calibration method }Non-breath DUI tester with automatic calibration and calibration method}

본 발명은 주취 운전자 단속 등에 사용하는 음주 감지기 중 별도로 호흡을 불어넣는 과정이 없이 감지를 수행하는 비호기식 음주감지기에서 자동으로 감지부(알코올 센서를 포함한다)를 교정하는 방법에 관한 것이다.The present invention relates to a method of automatically calibrating a detection unit (including an alcohol sensor) in an aerobic breathing detector that performs detection without a separate breathing process among the breathing detectors used for controlling drunk drivers.

전통적인 음주감지기는 호흡을 불어넣어 주취자를 선별하였다면(이하 '호기식 음주감지기'), 비호기식 음주감지기는 호흡을 불어넣지 않고 차량 내 알코올 농도를 감지, 차량을 선별하는 방식의 음주 감지기이다. Traditional breathalyzer is a breathing detector that selects the alcoholic drinker by inhaling it (hereinafter referred to as ``breathable breathalyzer''), while an aerobic breathalyzer is a breathalyzer that detects the alcohol concentration in the vehicle without breathing and selects the vehicle.

현재 경찰 및 각종 기관에서 주취자 및 주취운전자를 선별하기 위해 사용하고 있는 호기식 음주감지기는 센서를 전문 교정 기관에서 주기적으로 교정한다. 그러나 비호기식 음주감지기는 그 특성 상 종래의 호기식 음주감지기보다 월등히 감도가 높아 주변의 공기 등의 영향을 상당히 받고, 이러한 사유로 수시 교정이 필요하다. 현재 새로이 개발되어 경찰 등에서 사용 중인 비호기식 음주감지기는 별도의 감도 조절 노브를 이용하여 센서 및 감지부를 적절히 조절하여야하나, 상당히 잦은 주기로 조절 노브로 교정이 필요하며, 사용자의 숙련도에 따라 감지기의 감도 차이가 발생하는 문제점이 있다.The breathing type breathalyzer, which is currently used by police and various institutions to select drunk drivers and drunk drivers, periodically calibrates the sensor by a professional calibration institution. However, due to its characteristics, the aerobic breathing detector is significantly more sensitive than the conventional breathing detector and is significantly affected by the surrounding air, and for this reason, frequent correction is required. The aerobic breathing detector, which is currently newly developed and used by the police, must properly adjust the sensor and the detection unit using a separate sensitivity control knob, but it needs to be calibrated with the adjustment knob at a fairly frequent cycle, and the sensitivity of the sensor varies according to the user's skill level. There is a problem that occurs.

상기 문제점을 보완하기 위한 본 발명은, 차량 외부의 공기를 이용해 음주감지기의 감지부(알코올 센서를 포함한다)를 교정하는 방법 및 해당 교정 기능이 적용된 비호기식 음주감지기에 대한 것이다.The present invention for supplementing the above problem relates to a method of calibrating a detection unit (including an alcohol sensor) of a breathalyzer using air outside a vehicle and an aerobic breathalyzer to which the corresponding calibration function is applied.

본 발명을 통하여 단속자가 별도의 수동 교정을 행할 필요가 없이, 항상 규정된 감도 이상을 유지하는 비호기식 음주감지기를 개발 및 제조 할 수 으며, 이로서 그 사용성과 감도를 향상시킬 수 있다.Through the present invention, it is possible to develop and manufacture an aerobic breathing detector that always maintains more than a prescribed sensitivity without the need for a separate manual calibration by a regulator, thereby improving its usability and sensitivity.

본 발명의 바람직한 실시 예는 주취 운전자 단속을 위하여 사용되는 비호흡식 음주 감지기에서, 센서의 자동 교정을 수행하는 것에 있다. A preferred embodiment of the present invention is to perform automatic calibration of the sensor in a non-breathing breath detector used to control drunk drivers.

본 발명의 한 가지 구체적 구현 예시로서, 센서는 알코올 농도를 지속적으로 추적하고, 이 중 최소값에서 일정 수치를 더한 값을 기준치로 설정하도록 구성한다. 이는 선별 대상인 주취 의심 차량의 내부 알코올 농도가 외부 공기의 농도보다 높을 것을 상정한 것이다. 기준치 이상의 센서 값이 감지되면 알코올이 감지된 것으로 간주하며, 경보를 송출할 수 있도록한다. 상기 과정은 아날로그, 디지털 회로 내지 펌웨어, 소프트웨어로서 수행한다.As one specific implementation example of the present invention, the sensor is configured to continuously track the alcohol concentration and set a value obtained by adding a predetermined value from the minimum value as a reference value. This is assuming that the alcohol concentration inside the vehicle that is suspected of drinking alcohol is higher than the concentration of the outside air. If a sensor value above the reference value is detected, alcohol is considered to be detected, and an alarm can be sent out. The above process is performed as analog, digital circuits, firmware, and software.

본 발명은 상기의 예시를 참고로 더욱 상세히 설명되며, 상기의 예가 본 발명을 제한하려는 것은 아니다.The present invention is described in more detail with reference to the above examples, and the above examples are not intended to limit the present invention.
