Description

압력용기 이력관리장치 및 그의 충진방법{PRESSURE VESSEL HISTORY MANAGEMENT APPARATUS AND ITS USING METHOD}PRESSURE VESSEL HISTORY MANAGEMENT APPARATUS AND ITS USING METHOD}
본 발명은 압력용기 이력관리장치 및 이를 이용한 충진방법에 대한 것으로서, 압력용기의 상태 및 사용이력을 사용자에게 통지할 수 있는 압력용기 이력관리장치 및 충진방법에 대한 것이다.The present invention relates to a pressure vessel history management apparatus and a filling method using the same, and to a pressure vessel history management apparatus and a filling method that can notify the user of the state and history of use of the pressure vessel.
압력용기는 내부에 고압의 연료를 저장하는 용기로서, LPG, CNG 등과 같은 고압의 연료를 저장하는데 사용된다.The pressure vessel is a container for storing the high pressure fuel therein, and is used to store the high pressure fuel such as LPG and CNG.
압력용기는 충진소 및 이동식 운송장치에 부착된 모든 압력용기 등에 광범위하게 적용되고 있다.Pressure vessels are widely applied to all pressure vessels attached to filling stations and mobile transportation equipment.
압력용기는 통상적으로 고압을 견디기 위해 강재 등으로 제작되나 압력용기라도 충진 시에는 팽창되고, 사용 시에는 수축되며, 외부에서의 주기적인 진동과 충격에 의한 피로 균열이 발생하게 된다.Pressure vessels are usually made of steel to withstand high pressure, but even pressure vessels are expanded during filling, contracted during use, and fatigue cracks are generated by periodic vibrations and impacts from the outside.
이와 같이 균열이 발생한 압력용기를 계속해서 사용하게 되면 누수 및 폭발의 문제가 발생하여 안전성이 크게 위협 받게 된다.Continued use of pressure vessels in which cracks occur in this way causes problems of leakage and explosion, which greatly threatens safety.
신규제작 검사와 주기적인 안전검사의 경우 공기 또는 물을 통하여 가압 상태에서 테스트를 하는 방법이 존재하기는 한다.For new manufacturing and periodic safety inspections, there are methods for testing under pressure through air or water.
그러나, 상기 방법은 압력용기의 표면에 구멍이 관통되어 있어야만 누수 또는 누유를 통한 확인이 가능한 것인 바, 제품 표면에 있는 압력용기에 결함이나 균열이 존재하나 누수나 누유가 발생하지 않는 경우에는 확인이 곤란한 단점이 존재한다.However, the method can be confirmed by leaking or leaking only when a hole is penetrated through the surface of the pressure vessel. If a defect or crack exists in the pressure vessel on the product surface but no leakage or leakage occurs, This difficult drawback exists.
압력용기에 결함이나 균열이 발생한 경우 당장이 아니더라도 예측할 수 없는 향후 시점에 폭발이나 화재가 발생할 위험성이 존재하게 된다.If the pressure vessel is defective or cracked, there is a risk that an explosion or fire may occur at an unpredictable future, even if not immediately.
또한, 압력용기를 오래 사용한 경우 사용자가 압력용기에 대한 이력을 확인할 수 없어 교체주기나 보수 시기를 판단할 수 없게 되므로 사고의 위험성이 계속 존재하는 문제점이 발생한다.In addition, when the pressure vessel is used for a long time, the user cannot check the history of the pressure vessel, so it is not possible to determine the replacement cycle or the maintenance time, so there is a problem that the risk of an accident still exists.
한편, 압력용기는 폭발의 위험성으로 인해 두꺼운 금속재료를 성형하여 제작되어야 하는 데, 이 경우 압력용기의 무게가 증가되어 취급이 용이하지 않으며 차량 등의 연비를 저감시키는 문제를 발생시키게 된다.On the other hand, the pressure vessel has to be manufactured by molding a thick metal material due to the risk of explosion, in this case, the weight of the pressure vessel is increased, which is not easy to handle and causes a problem of reducing fuel consumption of the vehicle.

이와 같이 압력용기가 복합소재로 이루어진 경우에는 외부에 둘러싸인 탄소섬유층에 의해 압력용기의 기밀이나 이력관리가 더욱 곤란하게 되는 바, 전술한 문제점은 더욱 심각하게 된다.When the pressure vessel is made of a composite material as described above, the airtightness or history management of the pressure vessel becomes more difficult by the carbon fiber layer surrounded by the outside, and the above-described problems become more serious.

본 발명의 압력용기 이력관리장치에서는 해당 압력용기의 고유 식별부를 통해 충진횟수를 미리 파악하여 각 소재에 대해 정해진 피로 파괴횟수를 초과하는 경우 경고신호를 발송하여 위험성을 사용자에게 통지한다.In the pressure vessel history management device of the present invention, the number of fillings is determined in advance through a unique identification unit of the corresponding pressure vessel, and a warning signal is sent to the user by sending a warning signal when the number of fatigue breakages for each material is exceeded.
따라서, 사용자는 경고신호를 고려하여 피로파괴관점에서 이미 사용가능횟수가 초과된 압력용기에 해당하는 경우 이를 교체하거나 수선하게 하여 폭발사고나 화재 등을 미리 예방하는 효과를 가지게 된다.Therefore, in consideration of the warning signal, the user has an effect of preventing explosion accidents or fire by replacing or repairing the pressure vessel when the available number of times is already exceeded in the fatigue failure point.
게다가, 가스 충진 후에는 충진횟수를 압력용기의 고유 식별부에 저장함으로써 향후 충진 시 이를 활용하여 사고를 방지할 수 있게 하는 장점을 가진다.In addition, after filling the gas by storing the number of filling in the unique identification portion of the pressure vessel has the advantage that can be used to prevent accidents in the future filling.
또한, 본 발명의 압력용기 이력관리장치에서는 측정되는 압력용기의 응력-변형율 곡선에서 변형율이 해당 압력용기 소재의 기준 항복 변형율을 초과하는 경우또는 측정된 응력-변형율 곡선의 탄성구간이 압력용기 소재 고유의 응력-변형율 탄성구간에서 미리 정해진 허용범위를 넘는 경우 사용자에게 변형율 이상상태에 대한 경고신호를 발송하여 이를 통지하게 된다.In addition, in the pressure vessel hysteresis management apparatus of the present invention, when the strain in the stress-strain curve of the pressure vessel measured exceeds the standard yield strain of the pressure vessel material or the elastic section of the measured stress-strain curve is inherent in the pressure vessel material. If the stress-strain elastic section of the sensor exceeds the predetermined allowable range, a warning signal for abnormal state of strain is sent to the user.
사용자는 이러한 경고신호를 참조하여 해당 압력용기를 계속 사용하거나 교체/수선할 것인 지 여부를 결정하게 되는 바, 역시 압력용기의 균열이나 손상으로 인한 사고를 미연에 방지하는 효과를 가지게 된다.The user decides whether to continue to use or replace / repair the pressure vessel with reference to the warning signal, which also has the effect of preventing an accident due to crack or damage of the pressure vessel.
마찬가지로, 변형율 이상상태 경고신호에 대한 내용도 압력용기의 고유 식별부에 저장함으로써 향후 충진시 참고자료로 활용할 수 있게 하는 효과를 가진다.Likewise, the information on the strain abnormal state warning signal is also stored in the unique identification part of the pressure vessel, so that it can be used as a reference for future filling.
또한, 경고신호가 일정기간 이상 계속되는 경우 사용자가 이를 간과한 것으로 판단하여 강제로 밸브를 폐쇄시킴으로써 사고의 발생을 근본적으로 차단하는 장점을 가진다.In addition, when the warning signal continues for more than a certain period of time, the user judges that it is overlooked, and has the advantage of fundamentally blocking the occurrence of the accident by forcibly closing the valve.
한편, 본 발명의 이력관리장치는 압력용기가 내부에 금속소재 실린더가 형성되고 외부에 탄소섬유 필라멘트가 감기는 복합층으로 이루어진 경우에도 금속소재 실린더에 변형율 측정장치가 커버에 의해 장착가능하게 되는 바, 내부에 존재하는 금속소재 실린더의 균열 등의 흠결에 대해서도 용이하게 파악할 수 있는 장점을 가진다.On the other hand, the history management device of the present invention is that the strain measuring device to the metal material cylinder can be mounted by the cover even when the pressure container is formed of a metal material cylinder therein and the carbon fiber filament is wound in the composite layer In addition, there is an advantage that it is easy to grasp defects such as cracks in the metal material cylinder existing therein.

압력용기(100)는 도 1 에 도시된 바와 같이 내부가 빈 원통형상의 금속소재실린더(110)로 이루어진다. 또한, 압력용기(100)를 복합소재로 형성하는 경우도 있는 데 이 경우에는 도 2 에 도시된 바와 같이 실린더(110)의 외부에 유리섬유나 탄소섬유 필라멘트를 와인딩하여 복합재층(120)를 형성하는 것도 가능하게 된다.The pressure vessel 100 is composed of a cylindrical metal material cylinder 110 is hollow as shown in FIG. In addition, the pressure vessel 100 may be formed of a composite material. In this case, the composite layer 120 is formed by winding glass fiber or carbon fiber filament on the outside of the cylinder 110 as shown in FIG. 2. It is also possible.
한편, 압력용기(100)에는 고유식별부(130)를 형성할 수 있다. 고유식별부(130)는 RFID 태그, NFC(Near Field Communication) 태그 등과 같이 압력용기(100)의 고유한 정보, 예를 들어 제작일, 충진횟수, 압력용기 소재에 따른 피로파괴횟수, 항복점 변형율값을 포함하는 응력-변형율 곡선 정보 등이 입력되어 있으며 후술하는 바와 같이 충진회수 등과 같은 새로운 정보를 입력할 수 있는 구성을 가진다.On the other hand, the pressure vessel 100 may be formed with a unique identification unit (130). Unique identification unit 130, the unique information of the pressure vessel 100, such as RFID tag, Near Field Communication (NFC) tag, for example, the date of manufacture, the number of filling, fatigue breakdown frequency, yield point strain value according to the pressure vessel material Stress-strain curve information including the input is input, and has a configuration that can input new information, such as the number of filling, as described later.
압력용기(100)가 복합층으로 형성되는 경우 고유 식별부(130)는 외곽층인 복합재층(120)에 설치하는 것이 정보 식별에 있어 유리하다.When the pressure vessel 100 is formed of a composite layer, it is advantageous in the information identification that the unique identification unit 130 is installed in the composite layer 120 which is the outer layer.
한편, 압력용기(100)의 표면에는 변형율 측정장치로서 스트레인 게이지(200)가 장착되며 변형율 측정장치에 해당되는 것이면 다른 구성을 채택하는 것도 가능하다. 스트레인 게이지(200)는 일반적으로 사용되는 것으로 변형율을 측정하기 위해 사용되며 본 발명에서는 압력용기 표면의 변형율을 측정하는 데 사용된다.On the other hand, the strain gauge 200 is mounted on the surface of the pressure vessel 100 as a strain measuring device, and if it corresponds to the strain measuring device, another configuration may be adopted.

압력용기(100)가 도 2 에 도시된 바와 같이 복합재료로 형성되는 경우에 복합재층(120)이 금속소재 실린더(110)에 감기게 되면 스트레인 게이지(200)가 가압되어 변형율의 측정에 오차가 발생하기 쉽게 된다.When the pressure vessel 100 is formed of a composite material as shown in FIG. 2, when the composite layer 120 is wound around the metal cylinder 110, the strain gauge 200 is pressurized, thereby causing an error in the measurement of the strain rate. It is easy to occur.
따라서, 압력용기(100)가 복합재층으로 형성되는 경우에는 스트레인 게이치(200)의 상부에 커버(210)를 형성함으로써 복합재층(120)이 실린더(110)의 외주면에 감기는 경우에도 스트레인 게이지의 변형공간을 확보함으로써 정확한 변형율을 측정하는 것이 가능하게 된다.Therefore, when the pressure vessel 100 is formed of a composite layer, the strain gauge is formed even when the composite layer 120 is wound around the outer circumferential surface of the cylinder 110 by forming a cover 210 on the upper portion of the strain gate 200. It is possible to measure the exact strain rate by securing the strain space of.

또한, 제어처리부(620)에는 누설확인모듈이 포함됨으로써 차량이 정지 경우에도 압력계(300)에서의 압력이 지속적으로 유지되지 않는 경우 누설을 경고하는 작용을 하게 할 수 있다.In addition, the control processing unit 620 may include a leak check module to warn the leak when the pressure in the pressure gauge 300 is not continuously maintained even when the vehicle is stopped.
한편, 제어처리부(620)는 보조 스트레인 게이지가 추가로 설치된 경우, 주 스트레인 게이지의 고장여부를 확인하여 고장시에는 주 스트레인 게이지 대신에 보조 스트레인 게이지가 작동하도록 형성될 수 있다.On the other hand, the control processing unit 620 may be formed to operate the auxiliary strain gauge instead of the main strain gauge in case of failure by checking whether the main strain gauge is additionally installed, if the auxiliary strain gauge is additionally installed.
주 스트레인 게이지의 고장 여부는 밸브(400)의 개방 후 소정시간이 경과하였음에도 압력용기(100)의 변형율이 검측되지 않는 경우 이를 고장으로 판단한다. The failure of the main strain gauge is determined as a failure when the strain rate of the pressure vessel 100 is not detected even after a predetermined time has elapsed since the opening of the valve 400.
식별부 리더(610)에 의해 압력용기(100)의 고유 식별부(130)를 인식하여 해당 압력용기에 대한 고유 정보가 제어처리부(620)로 입력된다.The identification unit reader 610 recognizes the unique identification unit 130 of the pressure vessel 100, and unique information about the pressure vessel is input to the control processing unit 620.

도 3 은 본 발명의 압력용기 이력관리장치를 이용한 충진방법을 도시하는 흐름도이다.3 is a flowchart illustrating a filling method using the pressure vessel history management device of the present invention.
다음으로 이와 같이 형성된 압력용기 이력관리장치를 이용한 이력관리방법에 대해 설명한다.Next, a history management method using the pressure vessel history management device thus formed will be described.
먼저, 식별부 리더(610)가 고유 식별부(130)를 인식하여 해당 압력용기(100)에 대한 정보를 이력관리부(600)의 제어처리부(610)로 입력시키는 단계(s100)를 수행한다.First, the identification unit reader 610 recognizes the unique identification unit 130 and inputs the information on the pressure vessel 100 to the control processing unit 610 of the history management unit 600 (s100).
단계(s100)에서 고유 식별부(130)에는 해당 압력용기(100)에 대응하는 소재 고유의 응력-변형율 곡선 및 피로파괴횟수, 압력용기 제작일, 충진횟수 등의 내용이 입력되어 있는 데, 이러한 정보가 이력관리부(200)의 제어처리부(620)로 입력되게 된다.In the step (s100), the unique identification unit 130 has a material-specific stress-strain curve and fatigue breakdown frequency, pressure vessel production date, filling frequency, etc. corresponding to the pressure vessel 100 is input. Information is input to the control processing unit 620 of the history management unit 200.
도 4 는 금속소재에서 피로한도곡선을 도시하는 도면이다.4 is a diagram showing a fatigue limit curve in a metal material.
다음으로, 금번 충진횟수(N)가 피로 반복횟수(Nf)를 초과하는 지 여부를 판단하는 단계(s200)를 수행하여 충진횟수(N)가 피로 반복횟수(Nf)를 넘는 경우에는 경고신호를 발송하는 단계(s210)를 수행한다.Next, if the filling number (N) exceeds the fatigue repetition frequency (Nf) (s200) to determine whether the filling frequency (N) exceeds the fatigue repetition frequency (Nf), a warning signal is given. A step S210 of sending is performed.
도 4 에 도시된 바와 같이, 충진횟수(N)가 피로 반복횟수(Nf)를 넘는 경우에는 항복점을 넘지 않는 작은 응력이 작용하는 경우에도 압력용기(100)의 파손이 발생할 수 있기 때문이다.As shown in Figure 4, when the filling frequency (N) exceeds the fatigue repetition frequency (Nf) is because the breakage of the pressure vessel 100 may occur even when a small stress does not exceed the yield point.
따라서, 사용자는 상기 경고신호를 참조하여 압력용기를 교체하거나 수선 후 사용하는 등의 사전조치를 취할 수 있게 되어 사고를 방지할 수 있으며, 특히 가스 충진 전에 압력용기의 상태를 확인할 수 있어 사고의 위험은 더욱 감소하게 된다.Therefore, the user can take precautions such as replacing the pressure vessel or using it after repairing with reference to the warning signal, thereby preventing an accident, and in particular, checking the state of the pressure vessel before filling the gas may cause a risk of an accident. Is further reduced.
도 5 는 금속소재에서 응력-변형율 곡선을 도시하는 도면이다.5 is a diagram showing a stress-strain curve in a metal material.
충진횟수(N)가 피로 반복횟수(Nf)를 넘지 않는 경우에는 가스충진을 수행하면서 압력계(300)를 이용하여 충진되는 압력값을 측정하여 제어처리부(620)로 입력하는 단계(s300)를 수행한다.When the filling frequency (N) does not exceed the fatigue repetition frequency (Nf), while performing gas filling, measuring the pressure value filled using the pressure gauge 300 and inputting it to the control processor 620 (s300) is performed. do.
단계(s300)에서 제어처리부(620)에서는 압력값을 이용하여 압력용기에 작용하는 응력(σ= F(압력에 의해 작용하는 힘)/A(압력용기 단면적))을 연산한다.In step S300, the control processing unit 620 calculates the stress (σ = F (force acting by pressure) / A (pressure vessel cross-sectional area)) acting on the pressure vessel using the pressure value.
다음으로, 압력용기(100)에 가스가 충진되면서 발생하는 압력에 의한 변형율(ε= △/L)을 스트레인 게이지(200)를 통해 측정하는 단계(s400)를 수행한다.Next, the step (s400) of measuring the strain (ε = Δ / L) due to the pressure generated while the gas filled in the pressure vessel 100 through the strain gauge 200 is performed.
여기서 ㅿ : 변형량 (= L1 - L)Where ㅿ: strain (= L1-L)
L : 변형 전 원래길이L: Original length before deformation
L1 : 변형 후 길이L1: length after deformation
한편, 스트레인 게이지(200)를 복수로 형성한 경우, 하나의 스트레인 게이지가 고장인 경우 다른 스트레인 게이지를 통해 변형율을 측정하는 것이 가능하다.On the other hand, when a plurality of strain gauges 200 are formed, it is possible to measure the strain rate through the other strain gauge when one strain gauge is a failure.
즉, 가스충진이 진행된 후에 일정시간 경과 후에도 원래 이력관리부(600)에 연결된 주 스트레인 게이지가 작동하지 않는 경우 이력관리부(600)에 의해 보조 스트레인 게이지가 작동되어 변형량을 측정하는 것이 가능하다.That is, when the main strain gauge originally connected to the history management unit 600 does not operate even after a predetermined time after the gas filling is performed, the auxiliary strain gauge may be operated by the history management unit 600 to measure the deformation amount.
제어처리부(620)에서는 이와 같이 연산되어 입력된 응력 및 변형율을 곡선으로 표시한 다음, 압력용기 소재의 고유한 기준 응력-변형율(σ-ε) 곡선과 대비하여 변형율 이상여부를 판단하는 단계(s500)를 수행한다.The control processor 620 displays the calculated stresses and strains as curves and then determines whether or not the strains are higher than the inherent reference stress-strain (σ-ε) curves of the pressure vessel material (s500). ).
변형율 이상여부 판단단계(s500)는 2가지 방법의 어느 일방이나 양방에 의해 수행될 수 있다.Strain abnormality determination step (s500) may be performed by either one of the two methods.
하나의 방법은 도 5 에 도시된 바와 같이 측정된 응력-변형율 곡선의 탄성구간과 압력용기 소재 고유의 응력-변형율 곡선의 탄성구간과의 차이가 미리 정해진 범위, 예를 들어 ±10% 를 넘는 경우 변형율 이상으로 판단하는 방법이다.One method is the case where the difference between the elastic section of the stress-strain curve measured as shown in FIG. 5 and the elastic section of the stress-strain curve inherent in the pressure vessel material exceeds a predetermined range, for example, ± 10%. It is a method to judge more than a strain rate.
이 방법을 선택한 이유는 소재는 기본적으로 응력이 작용하는 경우에 탄성구간에서 변형율이 선형적으로 비례하여 변동되어야 하며 응력이 제거된 후에도 선형적으로 다시 회복되어야 하는 것이 정상인데, 이러한 범위를 벗어나서 거동하는 경우 압력용기의 소재가 노후가 균열 등으로 기본적으로 제 기능을 발휘하지 못하는 것으로 판단할 수 있기 때문이다.The reason for choosing this method is that it is normal for the material to change linearly proportionally in the elastic section when the stress is applied and to recover it linearly even after the stress is removed. In this case, the material of the pressure vessel can be judged that it is basically not functioning due to the cracking of the aging.
또한, 탄성구간에서는 응력-변형율 곡선은 직선으로 선형비례하므로 측정된 응력-변형율 곡선의 탄성구간과 기존 응력-변형율 탄성구간을 비교하기에 상대적으로 용이하기 때문이다.In addition, since the stress-strain curve is linearly proportional to the elastic section, it is relatively easy to compare the elastic section of the measured stress-strain curve with the existing stress-strain elastic section.
또 다른 방법은 변형율 값이 주어진 응력에서 항복점 변형율(εy)을 넘는 지 여부를 확인하는 방법이다.Another method is to determine whether the strain value exceeds the yield point strain (εy) at a given stress.
이 방법을 채택하는 이유는 도 5 에 도시된 바와 같이 변형율(ε)이 항복 변형율(εy)보다 높아지게 되는 경우 압력용기의 소재가 탄성구간을 벗어난 것을 의미하므로 언제든지 소성구간이나 파단점(F)으로 이동하게 되어 압력용기로서의 제 역할을 하지 못하게 될 가능성이 존재하기 때문이다.The reason for adopting this method is that when the strain ε becomes higher than the yield strain ε y as shown in FIG. 5, it means that the material of the pressure vessel is out of the elastic section, and therefore, at any time, This is because there is a possibility that the movement will not work as a pressure vessel.
상기 2가지 방법 중 어느 일방이나 양방에 있어서 변형율 이상여부가 발생되지 않은 경우 현재 충진횟수를 고유 식별부(130)에 저장하는 단계(s600)를 수행한다.In the case in which one or both of the above two methods do not have a strain rate abnormality, the current filling frequency is stored in the unique identification unit 130 (S600).
충진횟수는 가스 충진 시 밸브(400)의 노즐이 개방되는 개폐회수를 충진 횟수 정보를 확인 모션 센서(410)가 감지되어 제어처리부(620)로 송신하면, 제어처리부(620)에서 이를 식별부 리더(610)를 통해 고유 식별부(130)로 입력시키게 된다.The number of filling checks the number of filling times of opening and closing times in which the nozzle of the valve 400 is opened during gas filling. When the motion sensor 410 is detected and transmitted to the control processor 620, the control processor 620 identifies the reader. It is input to the unique identification unit 130 through 610.
또는, 스트레인 게이지(200) 작동횟수도 충진회수로 사용될 수 있으며 상기와 동일한 방식으로 고유 식별부(130)로 입력하는 것도 가능하다.Alternatively, the strain gage 200 may be used as the filling frequency and may be input to the unique identification unit 130 in the same manner as described above.
