In other words, the upper rod 212 is also in the form of a long pipe in the vertical direction, and enters or exits the lower rod 211 through the upper end of the lower rod 211.
상기 스프링(213)은 하부봉(211) 내에 설치되어 상부봉(212)을 상측으로 밀어 올리는 방향으로 탄성력을 제공한다.The spring 213 is installed in the lower rod 211 to provide an elastic force in a direction of pushing the upper rod 212 upward.
부연하면, 하부봉(211)의 상단에는 안쪽으로 연장된 이탈방지 플랜지(211a)가 형성되고, 상부봉(212)의 하단에는 바깥쪽으로 연장된 확장 플랜지(212a)가 형성되며, 하부봉(211)의 하부 내측면에는 안쪽으로 연장된 지지 플랜지(211b)가 형성된다.In other words, at the upper end of the lower rod 211, an inwardly extending anti-separation flange 211a is formed, and at the lower end of the upper rod 212, an outwardly extending extended flange 212a is formed, and the lower rod 211 A support flange 211b extending inwardly is formed on the lower inner surface of ).

한편, 본 발명에 의한 미세먼지 측정기(200)는 도 5 내지 도 7에 도시된 것과 같은 형태로 구성될 수도 있다.On the other hand, the fine dust measuring device 200 according to the present invention may be configured in the same form as shown in FIGS. 5 to 7.
도 5 내지 도 7에 도시된 미세먼지 측정기(200)는 로프(230)와, 상기 로프(230)에 일정간격으로 설치되는 고정함(240)과, 상기 고정함(240)에 설치되는 미세먼지센서(220)로 구성된다.The fine dust meter 200 shown in FIGS. 5 to 7 includes a rope 230, a fixing box 240 installed at regular intervals on the rope 230, and a fine dust installed in the fixing box 240 It consists of a sensor 220.
상기 로프(230)는 상단이 수술실의 천장에 연결되는 것으로서, 상단에 고리(231)가 구비되어 수술실의 천장에 구비된 고리(미도시) 등에 연결할 수 있고, 하단에는 무게추(232)를 설치하여 로프(230)를 팽팽하게 잡아당긴다. 물론 로프(230)의 하단에도 고리(미도시)를 구비하고 수술실의 바닥면에도 고리(미도시)를 구비하여 로프(230)의 하단을 수술실의 바닥면에 연결할 수도 있다.The rope 230 has an upper end connected to the ceiling of the operating room, and a hook 231 is provided at the upper end to be connected to a hook (not shown) provided on the ceiling of the operating room, and a weight 232 is installed at the lower end. to pull the rope 230 taut. Of course, a loop (not shown) may be provided at the lower end of the rope 230 and a loop (not shown) may be provided on the bottom surface of the operating room to connect the lower end of the rope 230 to the bottom surface of the operating room.
상기 고정함(240)은 원통형 박스와 유사한 형태로 제작된 것으로서, 상하를 관통하는 관통홀이 고정함(240)에 형성되고 이 관통홀을 로프(230)가 통과한다.The fixing box 240 is manufactured in a shape similar to a cylindrical box, and through-holes passing through the top and bottom are formed in the fixing box 240, and the rope 230 passes through the through-hole.
이러한 고정함(240)의 내부에는 로프(230)를 꼬아 만든 매듭(230a)이 수용되어 상기 매듭(230a)에 의해 고정함(240)이 지지된다.A knot 230a made by twisting a rope 230 is accommodated inside the fixing box 240, and the fixing box 240 is supported by the knot 230a.
부연하면 고정함(240)은 바디(241)와, 상기 바디(241)의 상단에 스크류 방식으로 체결되는 덮개(242)로 구성되는데, 이 매듭(230a)은 고정함(240)에 형성된 관통홀의 직경보다 크게 형성되어 매듭(230a)이 덮개(242)의 저면에 막힘으로써 로프(230)의 특정위치에 고정함(240)의 위치가 고정된다.In other words, the fixing box 240 is composed of a body 241 and a cover 242 fastened to the top of the body 241 by a screw method. The knot 230a is formed larger than the diameter and is blocked on the bottom surface of the cover 242, thereby fixing the position of the rope 230 to a specific position 240 is fixed.
그리고, 고정함(240)의 바디(241) 내부에는 고정함(240)의 상하방향보다는 긴 일정길이의 로프(230)가 절곡된 상태로 수납되어 있다.In addition, inside the body 241 of the fixing box 240, a rope 230 having a predetermined length longer than the vertical direction of the fixing box 240 is accommodated in a bent state.
또한, 고정함(240)의 상면과 저면에는 서로 부착되는 자석(243)이 설치된다. 즉 고정함(240)의 덮개(242) 상면과 고정함(240)의 바디(241) 저면에는 자석(243)을 각각 설치하여 미세먼지 측정기(200)를 사용하지 않을 때에는 로프(230)에 설치된 다수의 고정함(240)을 서로 밀착시킨다. 따라서 미세먼지 측정기(200)의 부피가 줄어들어 운반 및 관리가 용이해진다.In addition, magnets 243 attached to each other are installed on the upper and lower surfaces of the fixing box 240. That is, magnets 243 are installed on the upper surface of the cover 242 of the fixing box 240 and the bottom surface of the body 241 of the fixing box 240, respectively, and installed on the rope 230 when the fine dust detector 200 is not in use. The plurality of fixing boxes 240 are brought into close contact with each other. Therefore, the volume of the fine dust measuring device 200 is reduced, making it easy to transport and manage.
한편, 미세먼지센서(220)는 블루투스나 WIFI와 같은 무선통신망을 통하여 서버(400)와 전기적으로 연결되어 미세먼지센서(220)가 획득한 각종 데이터를 서버(400)에 전송할 수 있도록 구성하는 것이 바람직하고, 더불어 사용상의 편리성을 위하여 유선 충전보다는 무선충전 방식의 채택하거나 휴대용 배터리에 의해 전원이 공급되는 것이 바람직하다.On the other hand, the fine dust sensor 220 is electrically connected to the server 400 through a wireless communication network such as Bluetooth or WIFI, and is configured to transmit various data acquired by the fine dust sensor 220 to the server 400. Preferably, in addition, for convenience of use, it is preferable to adopt a wireless charging method rather than a wired charging method or to supply power by a portable battery.
상기 촬영장치(300)는 미세먼지 발생기(100)로부터 미세먼지가 공급되는 수술실의 내부 모습을 촬영하는 것으로서, 어안렌즈 또는 VR 카메라를 이용한다. 따라서 촬영장치(300)에 의해 촬영된 수술실의 영상은 입체적인 영상으로 구현된다.The photographing device 300 captures the inside of an operating room in which fine dust is supplied from the fine dust generator 100, and uses a fisheye lens or a VR camera. Therefore, the image of the operating room photographed by the photographing device 300 is implemented as a three-dimensional image.
그리고, 촬영장치(300)에 의해 촬영된 영상은 통신망을 통하여 서버(400)에 전송된다.Then, the image captured by the photographing device 300 is transmitted to the server 400 through a communication network.
상기 서버(400)는 다수의 미세먼지센서(220)가 측정한 미세먼지의 농도값을 제공받은 후 각 지점에서의 미세먼지 변화의 양상을 통해 수술실의 공기 흐름을 파악한다.After the server 400 receives the concentration value of the fine dust measured by the plurality of fine dust sensors 220, it determines the air flow in the operating room through the change of the fine dust at each point.
즉, 서버(400)에는 AI 알고리즘과 소프트웨어가 탑재되어 있기 때문에 미세먼지센서(220)가 위치되는 각 지점에서 미세먼지의 농도를 측정함으로써 그 측정값을 전달받으면 미세먼지가 어떤 흐름의 양상을 보이는지 파악할 수 있고, 이로부터 특정 수술실에서 공기가 어떤 흐름의 양상을 보이는지 계산하여 파악할 수 있다.That is, since the server 400 is equipped with an AI algorithm and software, by measuring the concentration of fine dust at each point where the fine dust sensor 220 is located, when the measured value is received, what kind of flow pattern the fine dust shows. From this, it is possible to calculate and figure out what kind of flow the air shows in a specific operating room.
한편, 서버(400)는 촬영장치(300)에 의해 촬영된 수술실의 내부 영상에 해당 수술실에서의 공기의 흐름을 보여주는 영상을 더하여 디스플레이(500)를 통하여 출력한다. 따라서 해당 수술실에서 공기가 어떻게 흐르는지를 시각적으로 명확하게 확인할 수 있다.Meanwhile, the server 400 adds an image showing air flow in the operating room to an image of the inside of the operating room photographed by the photographing device 300 and outputs the image through the display 500 . Therefore, it is possible to clearly see how the air flows in the operating room.
그리고, 서버(400)는 미세먼지 발생기(100)와도 전기적으로 연결되어 원격으로 미세먼지 발생기(100)를 조작 제어할 수 있을 뿐만 아니라 미세먼지 발생기(100)로부터 발생된 미세먼지의 배출량에 관한 정보를 제공받을 수 있으며, 미세먼지센서(220) 및 촬영장치(300)와도 전기적으로 연결되어 이들을 원격으로 조작 제어할 수 있다.In addition, the server 400 is electrically connected to the fine dust generator 100 to operate and control the fine dust generator 100 remotely, as well as information on the amount of fine dust generated from the fine dust generator 100. It can be provided, and it is electrically connected to the fine dust sensor 220 and the photographing device 300 to operate and control them remotely.
