Description
본 발명은 수소 충전 시스템에 관한 것이다.The present invention relates to a hydrogen charging system.
수소 연료는 내연기관의 연료와 달리 무색, 무취로 사람이 누설을 쉽게 감지할 수 없고, 특히 밀폐된 공간에서의 누설은 자연 발화나 폭발의 위험이 있기 때문에 수소 누설의 사전 감지가 필수적이다.Unlike internal combustion engine fuel, hydrogen fuel is colorless and odorless, making it difficult for humans to easily detect leaks. In particular, leaks in closed spaces have the risk of spontaneous combustion or explosion, so preliminary detection of hydrogen leaks is essential.
종래의 수소 충전 시스템은 하나의 공간 내에서 다수의 수소주입기를 통해 수소 수요처에 수소를 공급하여 충전하였다. 그러나 다수의 수소주입기에 각각 배속된 다수의 개폐밸브 중 어느 하나에서 누설이 발생되었을 때 정확한 누설 위치를 찾아내기 어려웠다.The conventional hydrogen charging system is charged by supplying hydrogen to hydrogen consumers through multiple hydrogen injectors within one space. However, when a leak occurred in one of the multiple on-off valves assigned to multiple hydrogen injectors, it was difficult to find the exact location of the leak.
그리고 누설 위치를 정확하게 찾기 위해서 수소 충전 시스템에 구비된 각 개폐밸브들 전체를 차단한 후 누설 위치를 찾기 위해 많은 시간과 노력이 요구되었다.And in order to accurately find the location of the leak, a lot of time and effort was required to find the location of the leak after blocking all of the on-off valves provided in the hydrogen charging system.
따라서, 본 발명의 목적은 누설 위치를 신속하고 정확하게 찾을 수 있는 수소 충전 시스템을 제공하는 것을 목적으로 한다.Therefore, an object of the present invention is to provide a hydrogen charging system that can quickly and accurately find the leak location.
본 발명은 다수의 수소주입기와 각 주입기에 배속된 개폐밸브를 갖는 수소 충전 시스템에 관한 것으로, 상기 다수의 수소주입기의 주변에 분산 설치되어 수소농도를 검출하는 다수의 수소센서 및, 상기 수소센서들로부터 수신된 수소농도 신호로부터 농도값이 높은 상위 세 곳의 수소센서 위치에 기초하여 추정 누설영역을 추정하며, 상기 추정 누설영역에 해당하는 수소주입기의 개폐밸브를 차단하는 제어부를 포함한다.The present invention relates to a hydrogen charging system having a plurality of hydrogen injectors and an opening/closing valve assigned to each injector, a plurality of hydrogen sensors distributed around the plurality of hydrogen injectors to detect hydrogen concentration, and the hydrogen sensors It estimates the estimated leakage area based on the positions of the top three hydrogen sensors with high concentration values from the hydrogen concentration signal received from and includes a control unit that blocks the opening/closing valve of the hydrogen injector corresponding to the estimated leakage area.
여기서, 상기 제어부는 상기 추정 누설영역에 관련된 개폐밸브의 차단 후 소정 시간 경과된 후 상기 수소센서들 중 적어도 어느 하나로부터 소정 농도 이상의 수소농도 신호가 발생되면 상기 수소센서들로부터 수신된 농도값이 높은 상위 세 곳의 수소센서의 위치에 기초하여 보정 누설영역을 추정하며, 상기 보정 누설영역 내의 수소주입기에 해당하는 개폐밸브가 차단되도록 제어하는 것이 바람직하다.Here, when a hydrogen concentration signal higher than a predetermined concentration is generated from at least one of the hydrogen sensors after a predetermined time has elapsed after blocking the on-off valve related to the estimated leakage area, the controller determines that the concentration value received from the hydrogen sensors is high. It is desirable to estimate the corrected leakage area based on the positions of the top three hydrogen sensors and control the opening/closing valve corresponding to the hydrogen injector within the corrected leakage area to be blocked.
상기 제어부는 상기 보정 누설영역 내의 개폐밸브가 차단된 후 소정 시간 경과된 후 상기 수소센서들로부터 소정 농도 이상의 수소농도 신호가 발생되면 상기 각 주입기에 배속된 개폐밸브들 전체가 차단되도록 제어하는 것이 바람직하다.Preferably, the control unit controls all on-off valves assigned to each injector to be blocked when a hydrogen concentration signal exceeding a predetermined concentration is generated from the hydrogen sensors after a predetermined time has elapsed after the on-off valve in the compensation leak area is blocked. do.
상기 제어부는 상기 각 주입기에 배속된 개폐밸브들 전체가 차단된 후 소정 시간 경과된 후 상기 수소센서들로부터 측정된 농도가 감소하는 것으로 판단되면 상기 보정 누설영역으로부터 가장 먼 곳에서 가까운 곳으로 시간차를 두고 상기 각 주입기에 배속된 개폐밸브들을 하나씩 개방하면서 상기 수소센서들을 통해 누설여부를 판단하는 것이 바람직하다.If the control unit determines that the concentration measured from the hydrogen sensors decreases after a predetermined time has elapsed after all on-off valves assigned to each injector are blocked, the control unit adjusts the time difference from the furthest point to the nearest point from the correction leak area. It is desirable to determine whether there is leakage through the hydrogen sensors while opening the on-off valves assigned to each injector one by one.
전술한 구성을 갖는 본 발명에 따르면, 누설 위치를 신속하고 정확하게 찾을 수 있어 수소 누설에 따른 안전사고를 예방할 수 있다.According to the present invention having the above-described configuration, the leak location can be quickly and accurately found, thereby preventing safety accidents due to hydrogen leak.

이하, 첨부도면을 참조하여 본 발명의 실시예에 따른 수소 충전 시스템을 구체적으로 설명한다.Hereinafter, a hydrogen charging system according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
도 1을 참조하면, 실시예에 따른 수소 충전 시스템(100)은 다수의 수소주입기(110), 개폐밸브(120), 다수의 수소센서(S), 제어부(130)로 이루어진다.Referring to FIG. 1, the hydrogen charging system 100 according to the embodiment consists of a plurality of hydrogen injectors 110, an opening/closing valve 120, a plurality of hydrogen sensors (S), and a control unit 130.
다수의 수소주입기(110)는 수소 저장탱크(10)에 저장된 수소를 공급받아 수소용기, 연료전지스택 등에 수소가 충전되게 한다. 다수의 수소주입기(110)와 수소 저장탱크(10)는 다수의 공급배관(20)을 통해 연결되며, 각 공급배관(20)에는 적어도 하나 이상의 공급밸브(22)가 설치된다.A plurality of hydrogen injectors 110 receive hydrogen stored in the hydrogen storage tank 10 and fill hydrogen containers, fuel cell stacks, etc. A plurality of hydrogen injectors 110 and a hydrogen storage tank 10 are connected through a plurality of supply pipes 20, and at least one supply valve 22 is installed in each supply pipe 20.
개폐밸브(120)는 각 주입기(110)에 배속되어 수소 저장탱크(10)로부터 수소의 공급 및 수소의 공급이 차단되게 한다. The on-off valve 120 is assigned to each injector 110 and blocks the supply of hydrogen from the hydrogen storage tank 10.
다수의 수소센서(S)는 각 수소 주입기(110)에 배속된 개폐밸브(120)들의 주변에 분산 설치되어 수소의 누설을 감지한다. 각 수소센서(S)들의 위치는 위치저장부(미도시)에 미리 저장된다. A plurality of hydrogen sensors (S) are distributed and installed around the on-off valves (120) assigned to each hydrogen injector (110) to detect hydrogen leakage. The positions of each hydrogen sensor (S) are stored in advance in a position storage unit (not shown).
여기서 각 수소센서(S)들은 도면에 도시하지 않았지만 각 수소주입기(110) 뿐만 아니라 각 공급배관(20)에 설치되어 있는 공급밸브(22)들의 주변에 분산 설치되어 있을 수 있다.Here, although not shown in the drawing, each hydrogen sensor S may be dispersedly installed around the supply valves 22 installed in each hydrogen injector 110 as well as each supply pipe 20.
제어부(130)는 수소센서(S)들로부터 수신된 수소농도 신호로부터 농도값이 높은 상위 세 곳의 수소센서 위치에 기초하여 추정 누설영역(P)을 추정하며, 추정 누설영역(P)에 해당하는 수소주입기(110)의 개폐밸브(120)를 차단한다.The control unit 130 estimates the estimated leakage area (P) based on the locations of the top three hydrogen sensors with high concentration values from the hydrogen concentration signals received from the hydrogen sensors (S), and corresponds to the estimated leakage area (P). Block the opening/closing valve 120 of the hydrogen injector 110.
제어부(130)는 각 수소센서(S)들로부터 수소의 농도값 정보를 연속적으로 제공받는다. 제어부(130)는 각 수소센서(S)들이 제공한 정보로부터 수소의 누설 여부를 판단할 수 있다.The control unit 130 continuously receives hydrogen concentration value information from each hydrogen sensor (S). The control unit 130 can determine whether hydrogen is leaking from the information provided by each hydrogen sensor (S).
또한 제어부(130)는 수소의 누설시 다수의 수소센서(S)들이 제공한 연속적인 농도값 정보들로부터 수소센서(S)들 각각의 시간-농도값 이력 정보를 획득할 수 있다. 시간-농도값 정보로부터 해당 수소센서(S)들의 시간에 따른 농도값 변화 즉, 농도 반응 속도를 알 수 있으며, 농도 반응 속도는 수소의 누설 위치와의 거리에 따라 다르다.Additionally, the control unit 130 may obtain time-concentration value history information for each hydrogen sensor (S) from continuous concentration value information provided by a plurality of hydrogen sensors (S) when hydrogen leaks. From the time-concentration value information, the concentration value change over time of the corresponding hydrogen sensors (S), that is, the concentration reaction speed, can be known, and the concentration reaction speed varies depending on the distance from the hydrogen leak location.
각 수소센서(S)들의 농도 반응 속도를 비교하기 위해서는 정량화된 수치값인 농도 반응 속도값이 필요하며, 비교 가능한 농도 반응 속도값으로는 미리 정해둔 농도값에 도달하는 시점의 시간이 이용된다.In order to compare the concentration response rate of each hydrogen sensor (S), a concentration response rate value, which is a quantified numerical value, is required, and the time at which a predetermined concentration value is reached is used as a comparable concentration response rate value.
도 2를 참조하면, 농도값이 높은 상위 세 곳의 수소센서(S1, S2, S3)는 각각 A, B, C 위치에 설치되어 있으며, 수소의 누설 위치는 P이다. 각 수소센서(S1, S2, S3)들이 수소의 누설에 반응하는 농도 반응 속도, 즉 시간에 따른 농도 변화는 서로 다르게 되며, 누설 위치에 가까운 수소센서의 농도 반응 속도가 상대적으로 더 빠르다.Referring to Figure 2, the top three hydrogen sensors (S1, S2, and S3) with high concentration values are installed at positions A, B, and C, respectively, and the hydrogen leak location is P. The concentration reaction speed of each hydrogen sensor (S1, S2, S3) in response to a hydrogen leak, that is, the concentration change over time, is different from each other, and the concentration reaction speed of the hydrogen sensor closer to the leak location is relatively faster.
도 3을 참조하면, A 위치에 있는 수소센서(S1)의 농도 반응 속도가 가장 빠르고, B 위치에 있는 수소센서(S2)의 농도 반응 속도가 다음으로 빠르고, C 위치에 있는 수소센서(S3)의 농도 반응 속도가 가장 느리다. 이에 따라 수소 누설 위치는 A 위치로부터 가장 가깝고 C 위치로부터 가장 먼 위치로 추정할 수 있다.Referring to Figure 3, the concentration response speed of the hydrogen sensor (S1) at position A is the fastest, the concentration response speed of the hydrogen sensor (S2) at position B is the next fastest, and the hydrogen sensor (S3) at position C is the fastest. has the slowest concentration reaction rate. Accordingly, the hydrogen leak location can be estimated as the location closest to location A and furthest from location C.
따라서 제어부(130)는 수소 누설시 농도값이 높은 상위 세 곳의 수소센서 각각의 농도 반응 속도 및 설치 위치를 기초하여 수소의 추정 누설영역(P)을 추정할 수 있다. 제어부(130)에 의한 수소의 추정 누설영역(P) 추정은 삼각 측량법을 이용하며, 삼각 측량법을 이용해 위치를 추정하는 것은 이미 잘 알려진 기술이므로 상세한 설명은 생략하기로 한다.Therefore, the control unit 130 can estimate the estimated hydrogen leakage area (P) based on the concentration response speed and installation location of each of the top three hydrogen sensors with high concentration values in the event of hydrogen leakage. The hydrogen leakage area (P) estimation by the control unit 130 uses triangulation, and since estimating the location using triangulation is a well-known technique, a detailed description will be omitted.
또한, 제어부(130)는 추정 누설영역(P)에 관련된 개폐밸브의 차단 후 소정 시간 경과된 후 수소센서(S1', S2', S3')들 중 적어도 어느 하나로부터 소정 농도 이상의 수소농도 신호가 발생되면 수소센서(S1', S2', S3')들로부터 수신된 수신된 농도값이 높은 상위 세 곳의 수소센서의 위치에 기초하여 보정 누설영역(P1)을 추정하며, 보정 누설영역(P1) 내의 수소주입기에 해당하는 개폐밸브가 차단되도록 제어한다.In addition, the control unit 130 receives a hydrogen concentration signal of a predetermined concentration or higher from at least one of the hydrogen sensors (S1', S2', and S3') after a predetermined time has elapsed after blocking the on-off valve related to the estimated leakage area (P). When this occurs, the correction leakage area (P1) is estimated based on the positions of the top three hydrogen sensors with high concentration values received from the hydrogen sensors (S1', S2', and S3'), and the correction leakage area (P1) is ) Control the opening/closing valve corresponding to the hydrogen injector to be blocked.
여기서, 추정 누설영역(P)에 관련된 개폐밸브의 차단 후 소정 시간 경과된 후 수소센서들로부터 수소농도 신호가 발생되지 않으면 수소의 누설 위치를 정확하게 찾은 것이다.Here, if a hydrogen concentration signal is not generated from the hydrogen sensors after a predetermined time has elapsed after blocking the on-off valve related to the estimated leakage area (P), the location of the hydrogen leak has been accurately found.
제어부(130)에 의한 보정 누설영역(P1)의 추정은 추정 누설영역(P)의 추정과 동일하므로 상세한 설명은 생략하기로 한다.Since the estimation of the corrected leakage area (P1) by the control unit 130 is the same as the estimation of the estimated leakage area (P), detailed description will be omitted.
제어부(130)는 보정 누설영역(P1) 내의 개폐밸브가 차단된 후 소정 시간 경과된 후 수소센서(S)들로부터 소정 농도 이상의 수소농도 신호가 발생되면 각 주입기(110)에 배속된 개폐밸브(120)들 전체가 차단되도록 제어한다. 여기서, 보정 누설영역(P1)에 관련된 개폐밸브의 차단하고 소정 시간 경과된 후 수소센서(S)들로부터 수소농도 신호가 발생되지 않으면 수소의 누설 위치를 정확하게 찾은 것이다.The control unit 130 operates the on-off valve assigned to each injector 110 when a hydrogen concentration signal of a predetermined concentration or higher is generated from the hydrogen sensors (S) after a predetermined time has elapsed after the on-off valve in the compensation leak area (P1) is blocked. 120) are controlled to be blocked. Here, if the hydrogen concentration signal is not generated from the hydrogen sensors (S) after a predetermined time has elapsed after blocking the on-off valve related to the correction leak area (P1), the location of the hydrogen leak has been accurately found.
계속해서 제어부(130)는 각 주입기(110)에 배속된 개폐밸브(120)들 전체가 차단된 후 소정 시간 경과된 후 수소센서(S)들로부터 측정된 농도가 감소하는 것으로 판단되면 보정 누설영역(P1)으로부터 가장 먼 곳에서 가까운 곳으로 시간차를 두고 각 주입기(110)에 배속된 개폐밸브(120)들을 하나씩 개방하면서 수소센서(S)들을 통해 누설여부를 판단한다.Subsequently, if the control unit 130 determines that the concentration measured from the hydrogen sensors (S) decreases after a predetermined time has elapsed after all of the on-off valves 120 assigned to each injector 110 are blocked, the control unit 130 determines the correction leak area. The opening/closing valves 120 assigned to each injector 110 are opened one by one with a time difference from the furthest point to the nearest point from (P1), and leakage is determined through the hydrogen sensors (S).
이와 같이 각 개폐밸브들을 보정 누설영역으로부터 가장 먼 곳에서 가까운 곳으로 시간차를 두고 하나씩 개방하면서 수소의 누설을 확인함에 따라 각 개폐밸브에 대한 누설 유무를 정확하고 신속하게 확인할 수 있다.In this way, by opening each on-off valve one by one with a time difference from the farthest to the nearest point from the compensation leak area to check for hydrogen leakage, the presence or absence of a leak for each on-off valve can be accurately and quickly confirmed.
이상 본 발명의 실시예를 첨부도면을 참조하여 설명하였지만, 당해 기술분야에 숙련된 사람은 하기의 청구범위에 기재된 본 발명의 기술적 사상으로부터 벗어나지 않는 범위 내에서 본 발명을 다양하게 수정 및 변경할 수 있음을 이해할 수 있을 것이다.Although embodiments of the present invention have been described above with reference to the accompanying drawings, a person skilled in the art may modify and change the present invention in various ways without departing from the technical spirit of the present invention as set forth in the claims below.
