Description
본 발명은 산소 포집 시스템에 관한 것으로서, 보다 상세하게는 대기중의 산소농도를 포함한 유해가스 농도 등을 측정하여 대상 위치의 대기 상태를 확인하는 산소농도 측정용 산소 포집 시스템에 관한 것이다.The present invention relates to an oxygen collection system, and more specifically, to an oxygen collection system for measuring oxygen concentration that measures the concentration of harmful gases, including oxygen concentration in the atmosphere, and confirms the atmospheric condition of the target location.
산업 공사환경에는 야외에 작업하는 것이 일반적이라고 생각되지만 의외로 배선공사, 터널공사, 지하시설공사 등 지하시설이나 밀폐된 지하공간에서 공사를 수행하는 환경이 다수 존재하며, 이러한 환경에서 발생하는 사고 중 평균 사고성 재해의 치명률이 1.1%일 때 질식사고의 치명률은 47.4%까지 높으며 이와 같은 통계는 질식사고 발생시 근로자의 절반가량은 사망한다고 볼 수 있다.It is thought that working outdoors is common in industrial construction environments, but surprisingly, there are many environments in which construction is performed in underground facilities or enclosed underground spaces, such as wiring work, tunnel construction, and underground facility construction, and the average number of accidents that occur in these environments is When the fatality rate of accidental accidents is 1.1%, the fatality rate of suffocation accidents is as high as 47.4%. These statistics show that about half of workers die when suffocation accidents occur.
또한, 밀폐된 지하공간 내 대기는 유해가스가 다수 포함되어 있을 수 있거나 산소가 부족할 수도 있지만, 이는 육안으로 파악할 수 없고, 위와 같은 환경에 노출된 이후 최소 몇십초에서 최대 몇분간 이후에 현재 대기에 이상이 있다는 사실을 몸으로 느꼈을 때는 이미 유해가스 중독인 상태거나, 산소가 부족하여 의식이 흐려지기 시작되는 시점이므로 타 산업사고에 비해 예방하는 방법이 쉽지 않은 편이다.In addition, the atmosphere in a closed underground space may contain many harmful gases or may be low in oxygen, but this cannot be detected with the naked eye, and the current atmosphere will remain in the atmosphere for at least a few tens of seconds to a maximum of several minutes after exposure to the above environment. By the time you physically feel that something is wrong, you are already in a state of poisoning from harmful gases or your consciousness begins to blur due to lack of oxygen, so prevention methods are not easy compared to other industrial accidents.
따라서, 작업공간 대기환경의 성분 중 산소 농도, 유해가스 농도, 온도, 습도, 분진량 등 작업자의 안전사고에 영향을 줄 수 있는 대기환경 측정값을 산출하여 작업자가 근무 가능한지 여부를 판단해주는 작업 공간 대기환경 분석 시스템에 대한 연구가 요구된다.Therefore, among the components of the work space air environment, the work space air environment determines whether the worker can work by calculating atmospheric environment measurements that can affect worker safety accidents, such as oxygen concentration, harmful gas concentration, temperature, humidity, and dust level. Research on environmental analysis systems is required.

또한, 상기 제어부(150)는, 상기 측정수단부(120)가 상기 단독 측정모드로 밀폐공간 또는 지하공간에서 대기환경을 측정할 때, 원활한 이동을 위해 조명부(123) 내 조명 중 상기 영상촬영부(122)의 영상촬영장치가 바라보는 방향에 위치한 조명만 빛을 조사하도록 제어하거나, 상기 이동부재의 파손 및 전복으로 인해 사용자 또는 작업자가 회수하러 가야할 상황에서 조명부(123)내 모든 조명이 0.5초 내지 2초 간격으로 불규척적으로 빛을 조사하도록 제어하여 쉽게 찾을 수 있도록 상기 조명부(123)를 제어할 수 있다.In addition, the control unit 150 controls the image capture unit among the lights in the lighting unit 123 for smooth movement when the measuring means unit 120 measures the atmospheric environment in an enclosed space or an underground space in the single measurement mode. The video recording device of (122) is controlled to emit light only from the lights located in the direction it is facing, or in a situation where the user or worker has to go to retrieve the moving member due to damage or overturning, all lights in the lighting unit (123) are turned on for 0.5 seconds. The lighting unit 123 can be controlled to emit light irregularly at intervals of 2 to 2 seconds so that it can be easily found.
한편, 상기 제어부(130)는, 상기 환기부(130)를 통해 폭발 위험 알림이 활성화된 경우, 상기 본체부(110)를 통해 통신연결된 상기 안전관리자의 단말로부터 신호를 수신받아 폭발위험 알림을 비활성화 하여 사용자가 작업범위를 벗어난 이후 에도 알림이 계속 울리지 않도록 제어할 수 있다.Meanwhile, when the explosion risk notification is activated through the ventilation unit 130, the control unit 130 receives a signal from the safety manager's terminal connected to communication through the main body unit 110 and deactivates the explosion risk notification.
