Description

폐쇄 공간용 산소 공급 시스템 및 이의 실행 방법Oxygen supply system for closed space and method of implementation thereof
본 발명은 폐쇄 공간용 산소 공급 시스템 및 이의 실행 방법에 관한 것으로, 보다 상세하게는 폐쇄 공간의 산소 용적량에 따라 자동으로 산소를 분사함으로써 폐쇄 공간에 있는 사용자의 산소량을 회복시켜 구토, 현기증, 무기력증, 극심한 피로감의 대부분을 극복할 수 있도록 하는 폐쇄 공간용 산소 공급 시스템 및 이의 실행 방법에 관한 것이다.The present invention relates to an oxygen supply system for a closed space and a method for implementing the same, and more particularly, by automatically injecting oxygen according to the oxygen volume of the closed space to restore the oxygen amount of the user in the closed space, vomiting, dizziness, lethargy, It relates to an oxygen supply system for a closed space that can overcome most of the extreme fatigue and a method for implementing the same.
밀폐된 공간의 공기는 생명체의 호흡에 의해 시간이 지나면서 이산화탄소의 함량이 증가하게 되어 생명체의 호흡에 지장을 주게 된다. The air in the enclosed space increases the carbon dioxide content over time due to the breathing of living things, which interferes with the breathing of living things.
즉, 운송 수단은 일정한 온도 유지와 공기압 유지, 외부 소음의 차단 및 디자인의 목적으로 외부와 밀폐된 형태로 제작되어 차량 등 운송 수단의 내부와 외부는 정도 차이는 있지만 거의 100%에 가깝게 단절되어 있는 상태이다.In other words, the means of transportation are manufactured in a sealed form from the outside for the purpose of maintaining a constant temperature, maintaining air pressure, blocking external noise, and designing. is the state
이러한 상태에서 차량 등 운송수단의 이용객인 사람이 장시간 운송수단을 이용할 경우 차량 등 운송수단의 내부 공기 중 산소 용적율이 급격히 감소하고 이산화탄소 용적율이 증가할 뿐만 아니라, 제한적 환기로 인하여 차량 등 운송수단의 내부 공기상태는 자연상태의 공기상태보다 현저하게 질적으로 악화될 수 밖에 없어, 이렇게 불량한 공기에 장시간 노출된 승객들은 차량 등 교통수단을 이용할 경우 구토증세, 현기증, 무기력증, 극심한 피로감 등을 호소하고 있다.In such a state, when a person who is a user of transportation means such as a vehicle uses transportation for a long time, the volume ratio of oxygen in the air inside the vehicle, such as a vehicle, decreases sharply, and the volume ratio of carbon dioxide increases. The air condition inevitably deteriorates qualitatively compared to the natural air condition, and passengers exposed to such poor air for a long time complain of vomiting, dizziness, lethargy, and extreme fatigue when using transportation means such as vehicles.
결국 이것은 단순히 차량 등 운송수단 내부의 공기정화장치를 이용한 먼지나 오염물질, 세균, 냄새 등을 정화시키는 것만으로 해결 될 수 없다. 즉, 내부 공기 중 산소용적률이 저하되어 있어 승객들의 체내에 필요한 산소량이 호흡을 통하여 부족하게 공급되기 때문이다. In the end, this cannot be solved by simply purifying dust, pollutants, bacteria, and odors using an air purifier inside a vehicle, etc. That is, because the oxygen volume ratio in the internal air is lowered, the amount of oxygen required in the body of passengers is insufficiently supplied through respiration.
즉, 내부공기의 정화문제에 한정되는 것이 아니라, 외부와 단절된 내부공기의 용적산소량을 일정 기준으로 증가시켜야만 해결될 문제이다.That is, it is not limited to the problem of purifying the internal air, but it is a problem to be solved only by increasing the volume of oxygen in the internal air that is cut off from the outside by a certain standard.
또한, 대단위 아파트 등 주거단지의 설계나 건축을 보면 외부공기와 내부공기가 창문을 열거나 특별한 환기장치를 가동하지 않는 한 차단되어 있는 것이 보통이다. In addition, when looking at the design or construction of residential complexes such as large-scale apartments, it is common that the outside air and the inside air are blocked unless a window is opened or a special ventilation device is operated.
이러한 경우, 실내의 오염된 공기를 실외의 신선한 공기로 대체해 줄 필요가 있으며, 최근 대두되고 있는 새집증후군 즉, 새집에서 발생하는 포름알데히드(HCHO) 및 휘발성 유기화합물(VOC)을 제거하기 위해 환기시스템의 필요성이 더욱부각되고 있는 실정이다.In this case, it is necessary to replace the indoor polluted air with fresh outdoor air, and ventilation is required to remove formaldehyde (HCHO) and volatile organic compounds (VOC), which are recently emerging in sick house syndrome.

산소 측정 센서(100_1~100_N)는 폐쇄 공간 각각에 위치하여 산소 정보를 센싱하여 산소 공급 제어 장치(400)에 제공한다. 이때, 산소 측정 센서(100_1~100_N)의 개수는 폐쇄 공간의 크기에 따라 변경될 수 있다. The oxygen measuring sensors 100_1 to 100_N are located in each of the closed spaces to sense oxygen information and provide it to the oxygen supply control device 400 . In this case, the number of oxygen measuring sensors 100_1 to 100_N may be changed according to the size of the closed space.
모션 감지 센서(200_1~200_N)는 폐쇄 공간 각각에 위치하여 모션 정보를 센싱하여 산소 공급 제어 장치(400)에 제공한다. 이때, 모션 감지 센서(200_1~200_N)의 개수는 폐쇄 공가의 크기에 따라 수용 가능한 인원 수의 모션을 측정할 수 있을 만큼의 개수로 결정될 수 있다.The motion detection sensors 200_1 to 200_N are located in each of the closed spaces to sense motion information and provide it to the oxygen supply control device 400 . In this case, the number of motion detection sensors 200_1 to 200_N may be determined to be sufficient to measure the motion of an acceptable number of people according to the size of the closed space.
산소 공급 장치(300)는 산소 공급 제어 장치(400)의 제어에 따라 산소를 분사하거나 산소를 발생시킨 후 이를 분사하는 장치이다. 이러한 산소 공급 장치(300)는 자동분사장치가 결합된 산소공급기와 이 산소공급기에 장착하는 일정한 용량의 규격화된 산소캔(산소용기)으로 구현될 수 있다. The oxygen supply device 300 is a device that injects oxygen or generates oxygen according to the control of the oxygen supply control device 400 and then injects it. The oxygen supplying device 300 may be implemented as an oxygen supply having an automatic injection device coupled thereto and a standardized oxygen can (oxygen container) of a certain capacity mounted on the oxygen supplying device.
즉, 산소 공급 장치(300)는 산소 공급 제어 장치(400)에 의해 폐쇄 공간의 산소 용적량이 임계 산소 용적량 이하이라고 판단되는 경우 산소 공급 제어 장치(400)의 제어에 따라 산소를 분사하거나 산소를 발생시키며, 산소 공급 제어 장치(400)에 의해 폐쇄 공간의 산소 용적량이 임계 산소 용적량 이상이라고 판단되는 경우 산소 공급 제어 장치(400)의 제어에 따라 산소 공급을 정지한다. That is, the oxygen supply device 300 injects oxygen or generates oxygen according to the control of the oxygen supply control device 400 when it is determined by the oxygen supply control device 400 that the oxygen volume of the closed space is equal to or less than the critical oxygen volume amount. When it is determined by the oxygen supply control device 400 that the volume of oxygen in the closed space is equal to or greater than the critical oxygen volume, oxygen supply is stopped according to the control of the oxygen supply control device 400 .
산소 공급 제어 장치(400)는 산소 측정 센서(100_1~100_N)로부터 수신된 산소 정보, 모션 감지 센서(200_1~200_N) 각각으로부터 수신된 모션 정보를 수신하고, 산소 정보 및 모션 정보를 이용하여 산소 용적량을 산출하고, 폐쇄 공간의 크기 및 모션 정보를 기초로 결정된 폐쇄 공간에 있는 예측 사용자의 수 따라 임계 산소 용적량을 결정한다. The oxygen supply control device 400 receives oxygen information received from the oxygen measurement sensors 100_1 to 100_N and motion information received from each of the motion detection sensors 200_1 to 200_N, and oxygen capacity using the oxygen information and motion information , and determine the threshold oxygen capacity according to the number of predicted users in the closed space determined based on the size and motion information of the closed space.
그런 다음, 산소 공급 제어 장치(400)는 산소 용적량 및 임계 산소 용적량을 비교하여 산소 용적량이 임계 산소 용적량 이하이면 산소를 공급하도록 산소 공급 장치(300)를 제어하며, 산소 공급 장치(300)가 산소를 공급하는 과정에서 산소 용적량이 임계 산소 용적량 이상이면 산소 공급을 중단하도록 산소 공급 장치(300)를 제어한다.Then, the oxygen supply control device 400 compares the oxygen volumetric amount and the critical oxygen volumetric amount to control the oxygen supply device 300 to supply oxygen when the oxygen volumetric amount is equal to or less than the critical oxygen volumetric amount, and the oxygen supplying device 300 provides oxygen When the oxygen volume is greater than or equal to the critical oxygen volume in the process of supplying the oxygen, the oxygen supply device 300 is controlled to stop the oxygen supply.

Then, the oxygen supply control apparatus 400 creates a motion information graph for each oxygen information by overlapping the oxygen measurement sensor position graph on which oxygen information is displayed and the motion detection sensor position graph on which the motion information is displayed.
이러한 산소 정보 별 모션 정보 그래프는 산소 측정 센서 위치 및 산소 측정 센서 위치를 기준으로 특정 반경에 위치하는 모션 감지 센서의 위치 및 모션 정보가 함께 표시되어 있는 그래프이다.The motion information graph for each oxygen information is a graph in which the position and motion information of the motion detection sensor located in a specific radius based on the position of the oxygen measurement sensor and the position of the oxygen measurement sensor are displayed together.
따라서, 산소 공급 제어 장치(400)는 산소 정보 별 모션 정보 그래프의 산소 측정 센서 위치를 기준으로 특정 반경에 위치하는 모션 감지 센서(200_1~200_N)에서 측정된 모션 정보를 이용하여 특정 반경 내에 위치하는 사용자의 수를 예측한다. Accordingly, the oxygen supply control device 400 is located within a specific radius using the motion information measured by the motion detection sensors 200_1 to 200_N located in a specific radius based on the oxygen measurement sensor position of the motion information graph for each oxygen information.

To this end, the oxygen supply control device 400 extracts the motion detection sensors 200_1 to 200_N that sense motion information among the motion detection sensors 200_1 to 200_N located in a specific radius based on the oxygen measurement sensor position, and the motion The number of corresponding motion detection sensors 200_1 to 200_N is predicted as the number of users according to at least one of whether the distance between the motion detection sensors 200_1 to 200_N that sensed the information is greater than or equal to a specific distance and the time difference when the motion information is sensed do.
