Description

Background
Field
The present disclosure relates to a water quality measurement system, and more particularly, to a smart water quality measurement system for culturing aquatic products, which can analyze a water quality state of a fish farm in real time by using a measurement apparatus for water pollutants inducing environmental stress.
Description of the Related Art
Environmental stress is a factor that inhibits growth of cultured aquatic life in fish farms and furthermore destroys the ecological environment, and refers to stress which is caused by lost feed or stress which is caused by secretions of fishes and shellfishes.
Increase of water pollutants inducing such environmental stress in fish farms may cause mass mortality of cultured aquatic life in fish farms, and discharge water of fish farms discharged to the outside may destroy the ecological environment.
To minimize water pollution and to take immediate measures against water pollution, systems for measuring and monitoring water pollution to measure a water quality state in real time are increasingly used.
As related-art technology, there is a system for monitoring water pollution by using an optical sensor as disclosed in patent literature 1. However, water quality information measured through the optical sensor used in this technology is merely information that is easy to measure by domestic technology, such as hydrogen ion concentration (pH), oxidation reduction potential (ORP), dissolved oxygen (DO), or sodium.
Water quality information such as NH4, NO2-, or NO3- may be measured by using expensive products to which foreign technology is applied, and purchase or procedures are complicated and a high cost is required to maintain.
The related-art technology disclosed in patent literature 1 also has a problem that pollutants are accumulated around the sensor and the accuracy and precision of the sensor are degraded. To solve this problem, a physical cleaning method for cleaning the sensor periodically by using a brush disposed in the proximity of the sensor is disclosed. However, cleaning by an apparatus for periodically cleaning may not be satisfactory when the sensor is heavily polluted, and thus there is still the problem that the accuracy and precision of water quality measurement are degraded.

For example, the environmental standard may be a standard that is established according to a purpose to preserve a natural state of waters and quality of water resources.
FIG. 1 is a view illustrating a smart water quality measurement system according to an embodiment of the present disclosure.
Referring to FIG. 1, the smart water quality measurement system 100 may include a measurement unit 100, a computer 200, a server 300, and a mobile terminal 400. These components are connected with one another by a network, and the network may be formed by, for example, Wi-Fi, Internet, local area network (LAN), wireless LAN, wide area network (WAN), personal area network (PAN), 3G, 4G, long term evolution (LTE), or a combination of two or more of these networks.
The measurement unit 100 may include a plurality of devices for measuring water quality information of a specimen for measuring water quality.
According to an embodiment, the measurement unit 100 may include a water temperature measurement device 110, a salinity measurement device 120, a DO measurement device 130, a pH measurement device 140, and a measurement apparatus 150 for an environmental stress-inducing water pollutant.
The water temperature measurement device 100, the salinity measurement device 120, the DO measurement device 130, and the pH measurement device 140 may include respective sensors to measure water temperature, salinity, DO, pH in the specimen, respectively. However, since these devices may be implemented by technology well known to ordinary skilled person in the related art, a detailed description thereof is omitted.
The environmental stress-inducing water pollutant measurement apparatus 150 may mix a specimen with a reagent that emits light due to the chemiluminescence reaction with an environmental stress-inducing water pollutant to be detected, and may measure whether the specimen includes the environmental stress-inducing water pollutant by measuring light emitted from the mixture (mixture of the reagent and the specimen). An exemplary configuration and an operation of the environmental stress-inducing water pollutant measurement apparatus 150 will be described hereinafter with reference to FIGS. 2 and 6.
The computer 200 may include an amplifier 210, an AD converter 203, a computer processor 205, and other resources (software and hardware), which are operatively connected with one another.
The amplifier 201 may be a signal amplifier that is manufactured to perform an operation having a constant function relationship between an input and an output, like an operational amplifier.

According to an embodiment, the computer 200 may receive an electric signal from a light detector 154 of the environmental stress- inducing water pollutant measurement apparatus 150 as water quality information.
Although will be described, the light detector 154 is a device that converts an intensity of detected light into an electric signal. The light detector 154 detects light emitted due to the chemiluminescence reaction between the specimen and the environmental stress-inducing water pollutant, and converts the light into an electric signal and transmits the electric signal to the computer 200. In the present embodiment, receiving, by the computer 200, the electric signal implies that light is emitted due to the chemiluminescence reaction and an environmental stressinducing water pollutant is included in the specimen. The computer 200 may amplify the electric signal received from the light detector 154 by the amplifier 201, and may convert the amplified signal into a digital signal by the AD converter 203, and may process the digital signal through the computer processor 205.
That is, the computer 200 may determine that the specimen is polluted when the electric signal is received from the light detector 154.
According to an embodiment, the computer 200 receives, as water quality information, water temperature data, salinity data, DO data, or pH data in the specimen from the water temperature measurement device 110, the salinity measurement device 120, the DO measurement device 130, or the pH measurement device 140. In the present embodiment, the computer 200 may determine that the specimen is polluted when the received water quality information indicates water temperature, salinity, DO, pH levels which do not meet a pre-defined environmental standard.

The mobile terminal 400 may include a service program 401, a user input/output device 403, a memory device 405, an operating system (OS) 407, and other resources (software and hardware) 409. The OS 407 may operatively connect hardware and application programs.
Herein, the service program 401, the user input/output device 403, the memory device 405, the OS 407, and the other resources (software and hardware) 409 are operatively connected with one another.
The mobile terminal 400 may be implemented by using various devices including a computer process, a memory, a display, hardware, software, a camera, and an application, such as a personal computer (PC), a smartphone, a smart watch, a tablet PC, a personal digital assistant (PDA) phone, a notebook PC. Herein, the smartphone refers to a cellular phone that provides an enhanced function in addition to functions of the PC, and the smart watch refers to an embedded system watch having more enhanced functions mounted therein than a normal watch. The tablet PC is a portable personal computer (PC) having a touch screen mounted therein as a main input device, and the PDA phone refers to a PDA that is provided with a mobile communication module.
The mobile terminal 400 transmits a control command to control a measurement operation of the measurement unit 100 to the server 300, and the server 300 transmits the control command to the computer 200, and the computer 200 controls the operation of the measurement unit 100 according to the control command. Herein, the control command may include a command to initiate water quality measurement, a command to stop water quality measurement, and a periodic water quality measurement command. That is, a user may manage measurement of water quality of a specimen in real time through setting for initiation, stop of water quality measurement, or periodic water quality measurement though the mobile terminal 400.
According to an embodiment, when the mobile terminal 400 transmits the water quality measurement initiation command to the server 300, the server 300 may transmit the water quality measurement initiation command to the computer 200. The computer 200 controls the operation of the measurement unit 100 to initiate water quality measurement according to the water quality measurement initiation command received from the server 300.
For example, the computer 200 may control the environmental stressinducing water pollutant measurement apparatus 150 to initiate water quality measurement according to the water quality measurement initiation command received from the server 300.
According to an embodiment, when the mobile terminal 400 transmits the water quality measurement stop command to the server 300, the server 300 transmits the water quality measurement stop command to the computer 200. The computer 200 may control the operation of the measurement unit 100 to stop water quality measurement according to the water quality measurement stop command received form the server 300.
According to an embodiment, the mobile terminal 400 may transmit the periodic water quality measurement command to the server 300. For example, the user may command to periodically measure water quality by setting to measure water quality information of a specimen every predetermined time (10 minutes) through the user input/ output device 403 of the terminal 400. The computer 200 may control the operation of the measurement unit 100 to measure water quality information of the specimen at intervals of the predetermined time (10 minutes) set by the user according to the periodic water quality measurement command received from the server 300.
Hereinafter, the measurement apparatus 150 for the environmental stressinducing water pollutant will be described with reference to FIG. 2 and 6.
As shown in FIG. 2, a measurement apparatus 150 for an environmental stress-inducing water pollutant according to an embodiment of the present disclosure includes a reagent supply unit 151 to supply a luminescence reagent to a sensor unit 159 in a constant quantity, and a sample constant supply unit 157 to supply a specimen to the sensor unit 159 in a constant quantity.
When the specimen includes an environmental stress-inducing water pollutant, which is detectable by a luminescence reagent, light is emitted due to a chemiluminescence reaction between the luminescence reagent and the environmental stress-inducing water pollutant, and thus it can be identified whether there exists the environmental stress-inducing water pollutant. Furthermore, according to an embodiment, a quantity of the environmental stress-inducing water pollutant may be identified.
A chemiluminescence reaction between a luminescence reagent and a target object to be detected refers to a phenomenon in which an electrically excited product is produced and the produced product directly emits light while returning to a ground state from the excited state, or emits light while transferring energy in the excited state to other molecules.
Since such a chemiluminescence reaction generally has a slow reaction speed, it is difficult to identify within a short time with naked eyes. Accordingly, the reaction may be accelerated by using an appropriate catalyst in the luminescence reagent. In the present disclosure, detectable environmental stress-inducing water pollutants perform the role of the catalyst, and the “target object to be detected” in the present disclosure refers to an environmental stress-inducing water pollutant included in the specimen.
Hereinafter, a detailed configuration of the measurement apparatus 150 for the environmental stress-inducing water pollutant which can detect an environmental stress inducing-water pollutant according to embodiments of the present disclosure will be described.
In the present disclosure, the “luminescence reagent” which emits light when reacting with the target object to be detected includes a “narrow-sense luminescence reagent” as a compound that cause a chemiluminescence reaction like luminol, and a “wide-sense luminescence reagent” as a mixture that causes a chemiluminescence reaction by mixing with various compounds. The term “luminescence reagent” will be used as long as the distinction has no benefit.
FIG. 2 is a view illustrating a structure of the measurement apparatus for the environmental stress-inducing water pollutant according to an embodiment of the present disclosure.
Referring to FIG. 2, the measurement apparatus 150 for the environmental stress-inducing water pollutant according to an embodiment may include the reagent supply unit 151, a plurality of peristaltic tubing pumps 153, a filter 155, the sample constant supply unit 157, and the sensor unit 159.

In addition, the filter 155 and the sample constant supply unit 157 may be positioned on a sample supply path, and the filter 155 may be positioned upstream from the sample constant supply unit 157. The sensor unit 159 may be positioned at a point where the sample supply path and the reagent supply path meet.
The sensor unit 159 may receive a luminescence reagent of a constant quantity from the reagent supply unit 151, and may receive a specimen of a constant quantity from the sample constant supply unit 157, and may be configured to mix the luminescence reagent and the specimen and to detect light from the mixture of the luminescence reagent and the specimen (hereinafter, referred to as a “mixture), thereby detecting a target object included in the specimen.
According to an embodiment, the reagent supply unit 151 stores the luminescence reagent and supplies the luminescence reagent to the sensor unit 159 in a constant quantity through the reagent supply path.
In embodiments of the present disclosure, the “reagent supply path” refers to a component that provides a space to allow the luminescence reagent stored in the reagent supply unit 151 to move therethrough. For example, the reagent supply path may be a pipeline that has a sealed inner space to allow a fluid to move therethrough without leakage.
According to an embodiment, the peristaltic tubing pumps 153a, 153b, 153c may be disposed downstream from the reagent supply unit 151 on the reagent supply path, and may pump the reagent from the reagent supply unit 151 and supply the reagent toward the sensor unit 159, and may control a supply of the supplied luminescent agent.
For example, the peristaltic tubing pumps 153a, 153b, 153c may supply a luminescence reagent of a predetermined quantity (hereinafter, a constant quantity) from the reagent supply unit 151 to the sensor unit 159 for a predetermined time.

As shown in FIG. 2, the reagent supply unit 151 may include a first reagent supply unit 151a to supply a first reagent R1, a second reagent supply unit 151b to supply a second reagent R2, and a third reagent supply unit 151c to supply a third reagent R3. The first reagent supply unit 151a may be configured to supply to the first reagent R1 to the sensor unit 159 in a first constant quantity, the second reagent supply unit 151b may be configured to supply the second reagent R2 to the sensor unit 159 in a second constant quantity, and the third reagent supply unit 151c may be configured to supply the third reagent R3 to the sample constant supply unit 157 in a third constant quantity.

For example, as shown in FIG. 1, the peristaltic tubing pumps 153a, 153b connected to the reagent supply units 151a, 151b, respectively, are connected to the T-shaped pipe 161, and the reagents R1, R2 outputted by the peristaltic tubing pumps 153a, 153b may be supplied to the sensor unit 159 in a mixed state. In addition, the reagent R3 outputted by the peristaltic tubing pump 153c may be supplied to the sample constant supply unit 157.
However, this is merely an example and only necessary reagents may be mixed.
According to an embodiment, the first reagent R1, the second reagent R2, and the third reagent R3 may have different functions, respectively, and a mixture including at least one of the first reagent R1, the second reagent R2, or the third reagent R3 may be supplied to the sensor unit 159. For example, the luminescence reagent to be supplied to the sensor unit 159 by the reagent supply unit 151 may be a mixture including at least one of the first reagent R1 or the second reagent R2, and the luminescence reagent to be supplied to the sample constant supply unit 157 by the reagent supply unit 151 may be the third reagent R3.

However, this is merely an example and is not limited, and various luminescence reagents which react with the target object to be detected and emit light may be used.
The sample constant supply unit 157 receives the specimen through the sample supply path and supplies the specimen to the sensor unit 159 in a constant quantity.
The “sample supply path” refers to a component that provides a space to allow the specimen that the sample constant supply unit 157 receives to move therethrough. For example, the sample supply path refers to a pipeline that has a sealed inner space to allow a fluid to move therethrough without leakage.
According to an embodiment, the sample constant supply unit 157 may receive the specimen from a sample repository R disposed on the sample supply path. The peristaltic tubing pump 153d may be disposed on the sample supply path to be connected to the sample repository, and may pump the specimen stored in the sample repository R and supply the specimen to the filter 155, and may control a supply of the specimen supplied to the filter 155 from the sample repository R.
According to an embodiment, the measurement apparatus 150 for the environmental stress-inducing water pollutant may further include the filter 155 disposed on the sample supply path.
The filter 155 may be positioned upstream from the sample constant supply unit 157 on the sample supply path. The filter 155 may filter the specimen supplied from the sample repository R and may provide the filtered specimen (treated water) to the sample constant supply unit 157.
According to an embodiment, the filter 155 may include an adsorptive resin column or an extraction coil including a masking agent. The masking agent may refer to a material for filtering an interference material interfering with the chemiluminescence reaction between the target material to be detected and the luminescence reagent from the specimen.
The filter 155 may filter by removing the interference material from the specimen by using the masking agent, or by extracting only the target material to be detected from the specimen.
Various luminescence reagents may be used according to a kind of an environmental stress-inducing water pollutant to be detected, and kinds of interference materials interfering with the reaction may vary according to luminescence reagents. Since the masking agent is variously configured to target an interference material according to a luminescence reagent and to remove the interference material, the environmental stress- inducing water pollutant can be detected more exactly and precisely.
FIG. 6 is a table showing luminescence reagents, interference materials, and masking agents according to target objects to be detected. Hereinbelow, specific examples will be described with reference to FIG. 5.
Example 1) where the target object to be detected is uric acid
To detect uric acid corresponding to the environmental stress-inducing water pollutant in the specimen, octyl phenyl polyglycol ether may be used as the first reagent R1, KMnO4 may be used as the second reagent R2, and HNO3 may be used as the third reagent R3. Ascorbic acid may be a material that interferes with the chemiluminescence reaction between these reagents and uric acid, and iron (III) ion (Fe (III)) which is a kind of iron oxide may be used as the masking agent to remove the interference material.
Example 2) where the target object to be detected is cobalt (II) ion (Co (II))
To detect cobalt (II) ion (Co (II)) corresponding to environmental stressinducing water pollutant in the specimen, luminol may be used as the first reagent R1, H2O2 may be used as the second reagent R2, and NaOH may be used as the third reagent R3. Iron (III) ion (Fe (III)) may be a material that interferes with the chemiluminescence reaction between the luminescence reagents and cobalt (II) ion (Co (II)), and ascorbic acid may be used as the masking agent to remove the interference material.

To detect 1-glutamic acid corresponding to the environmental stressinducing water pollutant in the specimen, peroxyoxlate may be used as the first reagent R1, H2O2 may be used as the second reagent R2, and HNO3 may be used as the third reagent R3. Potassium (I) ion (K (I)) and magnesium (II) (Mg (II)) may be materials that interfere with the chemiluminescence reaction between these reagents and 1-glutamic acid, and perylene may be used as the masking agent to remove the interference materials.
Hereinafter, an operation of the sample constant supply unit 157 will be described in detail with reference to FIG. 3.
Referring to FIG. 3, the sample constant supply unit 157 is configured to supply a specimen in a constant quantity. For example, the sample constant supply unit 157 may include a six-direction valve to supply the specimen in the constant quantity through a position change between a position A and a position B.
Hereinafter, the operation of the sample constant supply unit 157 will be described on the assumption that the sample constant supply unit 157 includes the sixdirection valve.
The sample constant supply unit 157 includes a main body B including six ports P1, P2, P3, P4, P5, P6 to receive or output a fluid, and pipes L1, L2, L3, L4, L5. Herein, the pipes L1, L2, L3, L4, L5 may be positioned outside the main body B to connect the ports or to connect with an external path (or pipe).
The first pipe L1 is a path for connecting the first port (or the port at the sample side) P1 and the sample supply path, specifically, the output of the filter 155, the second pipe L2 is a path for connecting the second port P2 and the fifth port P5, the third pipe L3 is a path for connecting the third port (or the port at the sensor side) P3 and the sample supply path, specifically, the input of the sensor unit 159, the fourth pipe L4 is a path for connecting the fourth port and a carrier repository (not shown), and the fifth pipe L5 is a path for connecting the sixth port P6 and a discharge portion (not shown).
That is, the first pipe L1 is to let the specimen outputted from the filter 155 be inputted to the first port P1, and the third pipe L3 is to let the specimen outputted from the third port P3 be inputted to the sensor unit 159.
A fluid does not always flow through the above-described pipes L1, L2, L3, L4, L5, and the fluid may flow through some of the pipes L1, L2, L3, L4, L5 and may not flow through the other pipes by an internal connection of the ports in the main body B. Herein, the internal connection may be changed by an operation of the six-direction valve (not shown) included in the main body B (herein, an operation of the valve is illustrated in the arrow direction).

In the position A, an internal connection is established in the main body B to connect the first port P1 and the second port P2, and an internal connection is established to connect the fifth port P5 and the sixth port P6. Herein, the third port P3 and the second port P2 are internally disconnected from each other, and the fourth port P4 and the fifth port P5 are internally disconnected from each other.
For the purpose of explaining the present disclosure, when the valve (not shown) is positioned to have the position A, the sample constant supply unit 157 is referred to as performing a constant filling operation. The constant filling operation is an operation of filling the specimen as much as a constant quantity, and in the present disclosure, the specimen may be filled in the second pipe L2.

For the purpose of explaining the present disclosure, when the valve is positioned to have the position B, the sample constant supply unit 157 is referred to as performing a constant supply operation. That is, the constant supply operation is an operation of supplying the specimen filled as much as the constant quantity in the constant filling operation to the sensor unit 159.
In the state of the position A (that is, the state of the constant filling operation), the specimen supplied to the first pipe L1 through the peristaltic tubing pump 153 is discharged to the outside through the first port P1, the second port P2, the second pipe L2, the fifth port P5, the sixth port P6, and the fifth pipe L5. In addition, the carrier may be provided to the sensor unit 159 through the fourth pipe L4, the fourth port P4, the third port P3, and the third pipe L3.
At a moment when the specimen is discharged to the outside through the fifth pipe L5, the sample constant supply unit 157 may be switched to the state of the position B (that is, the state of the constant supply operation).
When the sample constant supply unit 157 switches from the position A to the position B, the specimen supplied to the first pipe L1 through the peristaltic tubing pump 153 may be discharged to the outside through the first port P1, the sixth port P6, and the fifth pipe L5. In addition, when the carrier is supplied to the fourth pipe L4, the specimen filled in the second pipe may be supplied to the sensor unit 159 through the third port P3 by the carrier. Specifically, when the carrier is supplied to the fourth pipe L4, the carrier is provided to the sensor unit 159 through the fourth port P4, the fifth port P5, the second pipe L2, the second port P2, the third port P3, and the third pipe L3.
Herein, when all specimen stored in the third pipe L3 is supplied to the sensor unit 159, the sample constant supply unit 157 may switch to the state of the position A (that is, the state of the constant filling operation).
The operation in the position A and the operation in the position B are alternately performed as described above, such that the specimen is supplied to the sensor unit 159 as much as the constant quantity.

The flow cell 152 may include a reaction chamber 152a which accommodates the luminescence reagent and the specimen, and has an inner space tightly sealed. The reaction chamber 152a may be formed with a transparent material through which light is transmitted. However, in order to let light emitted from the inner surface transmit only through a portion (hereinafter, a “light transmission portion”) of the reaction chamber 152a, the other portion (hereinafter, “light non-transmission portion”) except for the light transmission portion may be surrounded by an opaque material.
The reaction chamber 152a may be formed with transparent glass (for example, borosilicate) or transparent plastic (for example, acrylic plastic) having good durability and high transmittance.
According to an embodiment, the reaction chamber 152a may be surrounded by an opaque material such as black PVC to prevent light from leaking through the other portion except for the light transmission portion.
The light detector 154 is coupled with the flow cell 152 to completely cover the light transmission portion which allows light to transmit therethrough in the reaction chamber 152.
According to an embodiment, the light detector 154 may have a light inflow hole (photo multiplier tube (PMT) hole) to receive light transmitted through the light transmission portion of the reaction chamber 152a, and may be tightly coupled with the flow cell 152 at a position where the light inflow hole (PMT hole) and the light transmission portion of the reaction chamber 152a correspond to each other. Herein, the light inflow hole may be formed to have a size to completely cover the light transmission portion of the reaction chamber 152a and may be coupled with the light transmission portion of the reaction chamber 152a in close contact therewith, such that light emitted from the light transmission portion of the reaction chamber 152a is transmitted only to the light detector 154.
According to an embodiment, the light detector 154 may include a converter which converts an intensity of light into an electric signal when light emitted from the light transmission portion of the reaction chamber 152a is detected, and outputs the electric signal. The converter may include a photo multiplier tube (PMT), a photomultiplier, a photodiode, or a photo transistor.
That is, the light detector 154 is a device that receives light and converts the light into an electric signal, and may additionally include an element for amplifying light and/or electric signal.
Referring to FIG. 1, water quality information measured in the environmental stress-inducing water pollutant measurement apparatus 150 corresponds to the electric signal outputted from the light detector 154, and the electric signal is transmitted to the computer 200, and the computer 200 may determine a degree of pollution of the specimen by analyzing characteristics of the electric signal.
For example, the computer 200 may determine whether the specimen includes the environmental stress-inducing water pollutant to be detected, by comparing the intensity of the electric signal and a reference value (a value predefined according to an environmental stress-inducing water pollutant). In addition, the computer 200 may determine a quantity of the environmental stress-inducing water pollutant to be detected by analyzing how much the intensity of the electric signal is greater than the reference value.
Various luminescence reagents may be used according to kinds of environmental stress-inducing water pollutants to be detected. Accordingly, the reference value may refer to a value which is pre-defined according to a luminescence reagent which varies according to an environmental stress-inducing water pollutant.

The wavelength of emitted light varies according to a kind of luminescence reagent. Therefore, when there are a plurality of luminescence reagents reacting in the flow cell 152, lights having different wavelengths are emitted.
The optical wavelength divider 156 is an optical element which divides light according to a wavelength upon receiving a light signal including lights of different wavelengths.
According to an embodiment, the optical wavelength divider 156 receives light emitted from the flow cell 152 and may divide the light into lights of different wavelengths and emit the lights.
The optical wavelength divider 156 and the flow cell 152 may be coupled to allow all lights emitted from the flow cell 152 to enter the optical wavelength divider 156 without being discharged to the outside.
The lights of different wavelengths divided by the optical wavelength divider 156 may be provided to the plurality of light detectors 154a, 154b, 154c, respectively.
