고정밀 실시간 표층수온염분측정 시스템{Thermosalinograph System for High Resolution and Real-time Data Aquisition}High-precision real-time surface water temperature and salinity measurement system {Thermosalinograph System for High Resolution and Real-time Data Aquisition}

본 발명은 고정밀 실시간 표층수온염분측정 시스템에 관한 것으로, 보다 상세하게는, 선박 내부에 설치하여 선박이 항해 또는 정선해 있는 위치의 표층 해수에 대한 고정밀의 수온, 염분, 전도도 데이터를 연속적이고 실시간으로 관측할 수 있으며, 자체 고장 진단이 가능하도록 고안된 고정밀 실시간 표층수온염분측정 시스템에 관한 것이다.The present invention relates to a high-precision real-time surface water temperature and salinity measurement system, and more particularly, it is installed inside a ship to continuously and in real time provide high-precision water temperature, salinity, and conductivity data for surface seawater at a location where the ship is sailing or stationary. It relates to a high-precision real-time surface water temperature and salinity measurement system designed to be observable and self-diagnostic.

일반적으로, 여객선이나 화물선을 포함하는 선박의 운행 또는 정박시에 표층 해수에 대한 수온, 염분, 전도도 등을 측정한다. In general, water temperature, salinity, conductivity, etc. of surface seawater are measured during operation or anchoring of a ship including a passenger ship or cargo ship.

표층수온염분측정센서는 별도의 공급장치에 의해 유입된 표층 해수가 시스템을 통과하는 동안 해수의 수온과 염분 및 전도도 등을 측정하게 된다. The surface water temperature and salinity sensor measures the water temperature, salinity, and conductivity of seawater while it passes through the system, introduced by a separate supply device.

이러한 해수의 조사 활동을 통하여 선박이 위치한 해양의 정보(수온, 염분, 전도도 등)를 실시간으로 획득함으로써, 단기간으로는 수온과 염분 변화를 통해 어장분초 변동을 바로 알 수 있고, 장기적으로는 기후변화에 의한 한반도 주변 해역의 연속적인 표층 변화를 모니터링하여 빅데이터를 구축할 수 있게 된다. By acquiring real-time information (water temperature, salinity, conductivity, etc.) of the ocean where the vessel is located through these seawater survey activities, changes in fishery areas can be immediately known through changes in water temperature and salinity in the short term, and climate change in the long term. It is possible to build big data by monitoring the continuous surface changes in the sea area around the Korean Peninsula.

As a prior art for measuring the salinity of such seawater, Korean Utility Model Publication No. 20-2008-0002787 (published on July 23, 2008) discloses a multifunctional salinity measuring device for ships.

그러나 이러한 선박용 다기능 염분측정장치는 조수기에서 생성된 담수의 염분을 측정함과 동시에 조수기에서 생성된 담수의 양을 유량측정장치를 이용하여 측정 및 표시하여주는 기능을 갖는 것으로, 표층 해수의 염분 및 수온, 전도도 등을 측정할 수 없는 문제점이 있었다. However, this multi-functional salinity measuring device for ships has a function of measuring and displaying the salinity of fresh water generated by the freshwater generator and at the same time measuring and displaying the amount of fresh water generated by the fresh water generator using the flow measurement device, and the salinity of surface seawater is measured. And there was a problem that water temperature, conductivity, etc. could not be measured.

도 1 내지 도 3에 도시된 바와 같이, 본 발명에 따른 고정밀 실시간 표층수온염분측정 시스템(10)은, 선박(100)에 설치되어 선박(100)이 위치한 해역의 표층 해수를 유입시켜 수온과 염분 및 전도도를 측정한 후 배출하도록 된 것으로, 표층 해수를 유입하도록 유입펌프(22)를 구비한 해수 공급부(20)와, 유입펌프(22)로부터 유입된 해수의 수온과 염분 및 전도도를 측정하기 위한 해수측정센서(30)와, 해수측정센서(30)를 통과한 해수를 배출하기 위한 배출펌프(42)를 구비한 해수 배출부(40)를 포함한다.1 to 3 , the high-precision real-time surface water temperature and salinity measurement system 10 according to the present invention is installed on the ship 100 and introduces the surface seawater of the sea area where the ship 100 is located, so that the water temperature and salinity and a seawater supply unit 20 having an inlet pump 22 to introduce the surface seawater, and the water temperature, salinity, and conductivity of seawater introduced from the inlet pump 22 to measure the conductivity and discharge it. and a seawater discharge unit 40 having a seawater measurement sensor 30 and a discharge pump 42 for discharging seawater that has passed through the seawater measurement sensor 30 .

그리고, 유입펌프(22)와 배출펌프(42) 사이에는, 해수측정센서(30)의 고장여부를 판단하기 위한 고장진단수단(50)이 마련된다. And, between the inlet pump 22 and the discharge pump 42, a fault diagnosis means 50 for determining whether the seawater measurement sensor 30 is faulty is provided.

고장진단수단(50)은, 해수측정센서(30)로 공급되는 해수의 온도를 측정하도록 유입펌프(22)와 해수측정센서(30) 사이의 유로관(70A)에 설치되는 제1 온도센서(52)와, 해수측정센서(30)를 통과한 해수의 온도를 측정하도록 해수측정센서(30)와 배출펌프(42) 사이의 유로관(70B)에 설치되는 제2 온도센서(54)로 이루어진다. The malfunction diagnosis means 50 is a first temperature sensor installed in the flow path 70A between the inlet pump 22 and the seawater measurement sensor 30 to measure the temperature of the seawater supplied to the seawater measurement sensor 30 ( 52) and a second temperature sensor 54 installed in the flow path 70B between the seawater measurement sensor 30 and the discharge pump 42 to measure the temperature of the seawater that has passed through the seawater measurement sensor 30 .

한편, 제2 온도센서(54)와 배출펌프(42) 사이의 유로관(70B)에는, 해수측정센서(30)를 통과한 해수가 자연 배수되도록 하여 유량과 유속을 안정시키기 위한 버퍼탱크(60)가 마련된다. On the other hand, in the flow path pipe 70B between the second temperature sensor 54 and the discharge pump 42, a buffer tank 60 for stabilizing the flow rate and flow rate by allowing the seawater that has passed through the seawater measurement sensor 30 to drain naturally. ) is provided.

이러한 버퍼탱크(60)에는 해수측정센서(30)를 통과한 해수의 수위를 감지하기 위한 수위감지센서(62)가 마련된다. The buffer tank 60 is provided with a water level sensor 62 for detecting the level of seawater that has passed through the seawater measurement sensor 30 .

그리고, 제1 온도센서(52)와 해수측정센서(30) 사이의 유로관(70A)에는 유량계(80A)가 설치되고, 해수측정센서(30)와 제2 온도센서(54) 사이의 유로관(70B) 또는 제2 온도센서(54)와 버퍼탱크(60) 사이의 유로관(70B)에는 유압을 측정하기 위한 유압계(80B)가 각각 설치된다. 유량계(80A)는 해수측정센서(30)로 유입되는 해수의 양을 측정하고, 유압계(80B)는 해수측정센서(30)로부터 배출되는 해수의 압력을 측정하기 위한 것이다. In addition, a flow meter 80A is installed in the flow path 70A between the first temperature sensor 52 and the seawater measurement sensor 30 , and the flow path pipe between the seawater measurement sensor 30 and the second temperature sensor 54 . A hydraulic pressure gauge 80B for measuring hydraulic pressure is installed in the flow path 70B between the 70B or the second temperature sensor 54 and the buffer tank 60, respectively. The flow meter 80A measures the amount of seawater flowing into the seawater measurement sensor 30 , and the hydraulic meter 80B is for measuring the pressure of seawater discharged from the seawater measurement sensor 30 .

한편, 해수감지센서(30)는, 'SBE21' 모델과 비교해 수온과 전도도의 분해능이 10 배나 높아 정밀한 데이터 획득이 가능한 'SBE45' 모델을 적용한다. 반면 해당 해수감지센서(30)는 ‘SBE21’ 모델과 비교해 요구 유량이 10~16 ㎖/sec으로 현저히 낮기 때문에 대량으로 입력되는 해수의 유량을 낮춰 일정하게 공급해야 하며, 이를 위해 유입펌프(22)는 소형 입력 펌프를 적용한다. On the other hand, the seawater sensor 30 applies the 'SBE45' model, which has a 10 times higher resolution of water temperature and conductivity compared to the 'SBE21' model, which enables precise data acquisition. On the other hand, the seawater sensor 30 has a significantly lower required flow rate of 10 to 16 ㎖/sec compared to the 'SBE21' model, so it is necessary to reduce the flow rate of seawater input in large quantity and supply it constantly, and for this purpose, the inflow pump (22) applies a small input pump.

또한, 버퍼탱크(60)는 해수측정센서(30)를 통과하여 사용된 해수의 일정하고 안정적인 배출을 위한 것으로, 해수측정센서(30)의 끝부분(유로관)이 배출펌프(42)와 직결될 경우, 배출펌프(42)의 동작시 해수의 강제 배출이 이루어져 시스템(10)의 유로관(70A,70B) 내부를 이동하는 유체의 유량 및 유속의 불규칙한 변동이 발생하게 되고, 이로 인해 데이터의 손실이 발생하게 된다. In addition, the buffer tank 60 is for a constant and stable discharge of the used seawater passing through the seawater measurement sensor 30 , and the end (flow pipe) of the seawater measurement sensor 30 is directly connected to the discharge pump 42 . In this case, when the discharge pump 42 is operated, the forced discharge of seawater is made, so that irregular fluctuations in the flow rate and flow rate of the fluid moving inside the flow pipes 70A and 70B of the system 10 occur. loss will occur.

따라서 배출펌프(42)의 작동력이 해수측정센서(30)에 영향을 미치지 않도록 배출펌프(42)의 영향력(해수를 강제배출시키는 힘)이 해수측정센서(30)(30)에 미치지 않도록 배출펌프(42)와 해수측정센서(30) 사이, 정확하게는 제2 온도센서(54)와 배출펌프(42) 사이에 전술한 버퍼탱크(60)가 설치되는 것이다. Therefore, so that the operating force of the discharge pump 42 does not affect the seawater measurement sensor 30, the influence of the discharge pump 42 (force to forcibly discharge seawater) does not affect the seawater measurement sensor 30, 30. Between the 42 and the seawater measurement sensor 30, precisely, the above-described buffer tank 60 is installed between the second temperature sensor 54 and the discharge pump 42 .

이러한 버퍼탱크(60)는, 해수측정센서(30)를 통과한 해수가 자연 배수되어 모이고, 일정 수위가 되면 수위감지센서(62)가 이를 감지하여 배출펌프(42)가 작동되록 한다. 이 과정으로 사용이 완료된 해수는 배출될 수 있으며, 이러한 구조에 의해 시스템(10) 내부의 유량과 유속을 안정시켜 노이즈 없는 데이터의 취득이 가능하게 된다. In the buffer tank 60, the seawater that has passed through the seawater measurement sensor 30 is naturally drained and collected, and when the water level reaches a certain level, the water level sensor 62 detects it and the discharge pump 42 operates. In this process, seawater that has been used can be discharged, and by this structure, the flow rate and flow rate inside the system 10 are stabilized, so that noise-free data can be acquired.

한편, 고장진단수단(50)은, 다음과 같이 작동된다. 즉, 해수가 시스템(10)을 이동하는 과정에서, 유입되는 해수의 온도를 제1 온도센서(52)가 측정하고, 제1 온도센서(52)를 통과하여 유입되는 해수의 온도를 해수측정센서(30)가 측정하며, 해수측정센서(30)를 통과한 해수의 제2 온도센서(544)가 감지하고, 제어부(90)는 제1 온도센서(52)와 해수측정센서(30) 및 제2 온도센서(54)가 감지한 해수의 온도값을 비교 분석하여 해수측정센서(30)의 고장유무를 판단할 수 있고, 고장으로 판단되는 경우에 경고메시지를 발생시켜 시스템(10)을 정지시키는 등을 조치를 취하도록 할 수 있다. On the other hand, the fault diagnosis means 50 is operated as follows. That is, in the process of seawater moving the system 10 , the first temperature sensor 52 measures the temperature of the incoming seawater, and the seawater measurement sensor measures the temperature of the incoming seawater through the first temperature sensor 52 . 30 is measured, the second temperature sensor 544 of the seawater that has passed through the seawater measurement sensor 30 detects, and the control unit 90 includes the first temperature sensor 52 and the seawater measurement sensor 30 and the second temperature sensor 544. 2 By comparing and analyzing the temperature value of the seawater detected by the temperature sensor 54, it is possible to determine whether the seawater measurement sensor 30 has a failure, and generates a warning message to stop the system 10 when it is determined to be a failure. You can take action, etc.

그리고, 전술한 과정으로 해수측정센서(30)로부터 취득한 해수에 대한 데이터는, 제어부(90)에 의해 취득된 데이터와 취득된 시간, 선박(100)의 위치 정보(GPS)를 함께 저장할 있다. 그리고 실시간 모니터링 기능이 통합된 운영 소프트웨어를 통해 시스템(10) 전체를 직관적이고 효율적으로 운용할 수 있다.In addition, data on seawater acquired from the seawater measurement sensor 30 through the above-described process may store the data acquired by the controller 90, the acquired time, and location information (GPS) of the vessel 100 together. In addition, the entire system 10 can be operated intuitively and efficiently through the operating software integrated with the real-time monitoring function.

전술한 바와 같이 구성된 표층수온염분측정 시스템(10)의 작용을 설명한다. The operation of the surface water temperature salinity measurement system 10 configured as described above will be described.

유입펌프(22)에 의해 유입된 해수는 제1 온도센서(52)를 통하여 해수측정센서(30)를 통과하면서 해수측정센서(30)에 의해 수온, 염분 및 전도도가 측정된다. 이어서 해수측정센서(30)를 통과한 해수는 제2 온도센서(54)를 통과한 후 버퍼탱크(60)에 임시 저장된다. 이와 같이 해수측정센서(30)를 통과한 해수가 버퍼탱크(60)로 자연배수되므로 해수측정센서(30)를 포함한 유로관(70A,70B) 내의 유량 및 유압, 유속 등이 일정하게 된다. The seawater introduced by the inlet pump 22 passes through the seawater measurement sensor 30 through the first temperature sensor 52 , and the water temperature, salinity and conductivity are measured by the seawater measurement sensor 30 . Subsequently, the seawater that has passed through the seawater measurement sensor 30 is temporarily stored in the buffer tank 60 after passing through the second temperature sensor 54 . As the seawater passing through the seawater measurement sensor 30 is naturally drained to the buffer tank 60 as described above, the flow rate, hydraulic pressure, and flow velocity in the flow pipes 70A and 70B including the seawater measurement sensor 30 become constant.

한편, 해수가 유입펌프(22)를 통과하여 제1 온도센서(52), 해수측정센서(30)와 제2 온도센서(54)를 통과하는 동안 제1 온도센서(52), 해수측정센서(30)와 제2 온도센서(54)가 해수의 온도를 측정한 후 이를 비교하여 해수측정센서(30)의 고장여부를 판단하게 된다. 이 과정으로 측정 신뢰도를 높일 수 있다. On the other hand, while the seawater passes through the inlet pump 22 and passes through the first temperature sensor 52, the seawater measurement sensor 30 and the second temperature sensor 54, the first temperature sensor 52, the seawater measurement sensor ( 30) and the second temperature sensor 54 measure the temperature of the seawater and compare it to determine whether the seawater measurement sensor 30 is malfunctioning. This process can increase the measurement reliability.
