Technical Field

The present invention relates to a water quality measuring system, and more particularly, to an intelligent water quality measuring system for aquaculture, which can analyze the water quality state of an aquaculture farm in real time using an environmental pressure-inducing substance measuring device.

Background

The environmental stress represents a stress due to a lost feed or a stress due to a secreted substance of fish and shellfish, etc., as a factor that hinders the growth of farmed organisms in an aquaculture farm and may further destroy the ecological environment.

Such an increase in the environmental pressure-inducing substances in the aquaculture farm leads to a large number of deaths of the cultured organisms in the farm, and causes problems in that the ecological environment is destroyed by the water discharged from the farm to the outside.

Recently, in order to prepare a timely countermeasure against water pollution while minimizing water pollution, the settings of water pollution measuring and monitoring systems for measuring the state of water quality in real time are increasing.

As disclosed in patent document 1, which is a prior art, there is a system for monitoring water pollution using an optical sensor. However, the water quality information that can be measured by the optical sensor used for this technique is only of a degree that is easy to measure by domestic techniques such as hydrogen ion concentration (pH), oxidation-reduction potential (ORP), oxygen dissolved amount (DO), or Sodium (Sodium).

Due to, for example, NH₄、NO^2-Or NO^3-The water quality information is generally obtained by using products to which expensive foreign technologies are applied, resulting in complicated purchase and flow processes and requiring a large amount of maintenance costs.

The prior art in patent document 1 also has a problem that contaminants accumulate around the sensor to degrade the accuracy and precision of the sensor, and in order to solve the problem, a physical cleaning method is disclosed in which periodic cleaning is performed using a brush or the like arranged around the sensor. However, the periodic cleaning device may not be sufficiently cleaned during a period of serious contamination, so that there may be a problem in that the accuracy and precision of the water quality measurement are lowered.

For example, the environmental standard may be a standard specified by a use in order to preserve the natural state of a water area and the quality of water resources.

Fig. 1 is a diagram for explaining an intelligent water quality measurement system according to an embodiment of the present invention.

Referring to fig. 1, the intelligent water quality measurement system may include a measurement unit 100, a computer 200, a server 300, and a mobile terminal 400, and these components may be connected via a Network, and the Network may be, for example, Wi-Fi, the Internet, a local Area Network (L AN: L oral Area Network), a Wireless local Area Network (Wireless L AN: Wireless L oral Area Network), a Wide Area Network (WAN: Wide Area Network), a Personal Area Network (PAN: Personal Area Network), 3G, 4G, L TE, or a combination of two or more of these.

The measurement section 100 may include a plurality of devices for measuring water quality information of the sample to be measured.

According to one embodiment, the measuring unit 100 may include a water temperature measuring device 110, a salinity measuring device 120, an oxygen dissolved amount (DO) measuring device 130, a hydrogen ion concentration (pH) measuring device 140, and an environmental pressure-inducing substance measuring device 150.

The water temperature measuring device 110, the salinity measuring device 120, the oxygen dissolved amount (DO) measuring device 130, and the hydrogen ion concentration (pH) measuring device 140 may be constituted by respective sensors for measuring the water temperature, the salinity, the oxygen dissolved amount (DO), and the hydrogen ion concentration (pH) in the sample. However, those skilled in the art, having an extent that can understand the present invention, can implement these means by a well-known technique, and thus detailed description is omitted.

The environmental pressure-inducing substance measurement device 150 mixes a sample with a reagent that can emit light by a chemiluminescent reaction with an environmental pressure-inducing substance to be detected, and measures the light emitted from the mixture (mixture of the reagent and the sample reagent) to determine whether or not the sample contains the environmental pressure-inducing substance. Further, an exemplary configuration and operation of the ambient pressure-inducing substance measurement device 150 will be described later with reference to fig. 2 to 6.

The computer 200 may include an amplification section 201, an AD converter 203, a computer processor 205, and other resources (software and hardware) (not shown), which may be operably connected to each other.

The amplifying section 201 may be a signal Amplifier such as an Operational Amplifier (Operational Amplifier) manufactured in such a manner as to be able to perform an operation having a predetermined functional relationship between an input and an output.

The AD converter 203 is a device that converts an analog signal into a digital signal, and in the present embodiment, the AD converter 203 may convert an analog signal received from the amplifying section 201 into a digital signal.

The computer 200 determines the degree of contamination of the sample based on the water quality information measured by the measuring unit 100.

According to one embodiment, the computer 200 may receive an electric signal as the water quality information from the light detection unit 154 constituting the environmental pressure-inducing substance measurement device 150.

The light monitoring unit 154 is a device capable of converting the intensity of the sensed light into an electrical signal, which will be described later. When the light detection section 154 detects light emitted by the chemiluminescent reaction between the sample and the environmental pressure-inducing substance, it converts the light into an electrical signal and transmits the electrical signal to the computer 200. In this embodiment, the computer 200 receives the electrical signal indicating that light is emitted by the chemiluminescent reaction, indicating that the sample includes the environmental pressure inducing substance. The computer 200 amplifies the electric signal received from the light detection section 154 by the amplification section 201, and the amplified signal may be converted into a digital signal by the AD converter 203 and processed by the computer processor 205.

That is, if the computer 200 receives an electric signal from the light detection unit 154, it can be determined that the sample is contaminated.

According to one embodiment, the computer 200 may receive water temperature data, salinity data, oxygen dissolution amount (DO) data, or hydrogen ion concentration (pH) data in the sample from the water temperature measuring device 110, the salinity measuring device 120, the oxygen dissolution amount (DO) measuring device 130, or the hydrogen ion concentration (pH) measuring device 140 as the water quality information. In this embodiment, the computer 200 may determine that the sample is contaminated when the received water quality information indicates a water temperature, a salinity, an oxygen dissolution amount (DO), and a hydrogen ion concentration (pH) that DO not satisfy predetermined environmental standards.

The server 300 receives the water quality information from the computer 200 and the degree of contamination of the sample determined by the computer 200, and stores and manages (deletes, changes, updates, and adds) the same.

The mobile terminal 400 may include a service 401, a user input output device 403, a memory device 405, an Operating System (OS) 407, and other resources (software and hardware) 409. An Operating System (OS) 407 may operatively connect the hardware and the application programs.

Here, a service program 401, a user input/output device 403, a storage device 405, an Operating System (OS) 407, and other resources (software and hardware) 409 are operatively connected.

The mobile terminal 400 may be implemented as, for example, a Personal Computer (PC), a smart phone, a smart watch, a tablet PC, a PDA phone, a notebook Computer, etc., which include a Computer processor, a memory, a display, hardware, software, a camera, and an application program. Here, the smart phone denotes a portable phone providing advanced functions while providing functions such as a PC, the smart watch denotes an embedded system watch mounted with further functions than a general watch, the tablet PC denotes a portable PC (Personal computer) mounting a touch screen as a main input device, and the PDA phone denotes a Personal information terminal (PDA) equipped with a mobile communication module.

The mobile terminal 400 transmits a control command for controlling the measurement operation of the measurement unit 100 to the server 300, the server 300 transmits the control command to the computer 200, and the computer 200 controls the operation of the measurement unit 100 based on the control command. Here, the control commands may include a water quality measurement start command, a water quality measurement stop command, and a periodic water quality measurement command. That is, the user can set the start and stop of the water quality measurement of the sample or the periodic water quality measurement by moving the terminal 400, thereby managing the water quality of the sample in real time.

According to an embodiment, if the mobile terminal 400 transmits a water quality measurement start command to the server 300, the server 300 transmits the water quality measurement start command to the computer 200. The computer 200 can control the operation of the measuring unit 100 based on the water quality measurement start command received from the server 300 to allow the measuring unit 100 to start the water quality measurement.

For example, the computer 200 may control the environmental pressure-inducing substance measuring device 150 in response to a water quality measurement start command received from the server 300 to start the water quality measurement by the environmental pressure-inducing substance measuring device 150.

According to an embodiment, if the mobile terminal 400 transmits a water quality measurement termination command to the server 300, the server 300 transmits the water quality measurement termination command to the computer 200. The computer 200 may control the operation of the measuring unit 100 so that the measuring unit 100 terminates the water quality measurement based on the water quality measurement termination command received from the server 300.

According to an embodiment, the mobile terminal 400 may transmit a periodic water quality measurement order to the server 300. For example, the user may set, via the input/output device 403 of the mobile terminal 400, to perform a periodic water quality measurement command by measuring the water quality information of the sample once for a predetermined time (10 minutes). The computer 200 may control the operation of the measuring unit 100 according to the periodic water quality measurement command received from the server 300 so that the water quality measuring unit 100 measures the water quality information of the sample at a predetermined time (10 minutes) set by the user as a period.

The ambient pressure-inducing substance measurement device 150 will be described in detail below with reference to fig. 2 to 6.

As shown in fig. 2, the environmental pressure-inducing substance measuring apparatus 150 according to an embodiment of the present invention includes: a reagent supply unit 151 for quantitatively supplying a luminescent reagent to the sensor unit 159; the sample quantitative supply unit 157 quantitatively supplies the sample to the sensor unit 159.

When the sample contains an environmental pressure-inducing substance detectable by the luminescent reagent, the presence or absence of the environmental pressure-inducing substance can be known by luminescence from a chemiluminescent reaction between the luminescent reagent and the environmental pressure-inducing substance. Further, according to embodiments, the amount of the ambient pressure inducing substance may also be known.

The chemiluminescence reaction between the luminescent reagent and the detection target is a phenomenon in which an electrically excited product is generated, and the product directly emits light while returning from an excited state to a ground state, or emits light by transferring energy of the excited state to another molecule.

Such a chemiluminescent reaction is usually slow, and thus is difficult to visually confirm in a short time. Therefore, the reaction can be promoted by using an appropriate catalyst in the luminescent reagent, and in the present invention, the detectable environmental pressure-inducing substance plays such a catalytic role, and the "detection object" in the present invention means the environmental pressure-inducing substance included in the sample.

In the following embodiments of the present invention, a specific configuration of the environmental pressure-inducing substance measuring device 150 capable of detecting the above-described environmental pressure-inducing substance will be described.

In the present specification, the "luminescent reagent" that emits light when reacting with a detection target is a compound that can undergo a chemiluminescent reaction, such as luminol (L luminol), and is used in a meaning including both "luminescent reagent in a narrow sense" and "luminescent reagent in a broad sense" that is a mixture that can undergo a chemiluminescent reaction by mixing a plurality of compounds.

Fig. 2 is a diagram for explaining the configuration of an ambient pressure-inducing substance measurement device according to an embodiment of the present invention.

Referring to fig. 2, the ambient pressure-inducing substance measurement apparatus 150 according to an embodiment may include a reagent supply unit 151, a plurality of tube-type pumps 153, a filter unit 155, a sample quantitative supply unit 157, and a sensor unit 159. Here, the reagent supply unit 151 and a part of the tube-type interlock pump 153 are located on the reagent supply path, and the reagent supply unit 151 is located upstream of the tube-type interlock pump 153. Also, the filter section 155 and the sample quantitative supply section 157 may be located on the sample supply path, with the filter section 155 located upstream of the sample quantitative supply section 157. Further, the sensor unit 159 is located at a point where the sample supply path and the reagent supply path meet each other.

The sensor unit 159 receives a quantitative amount of the luminescent reagent from the reagent supply portion 151 and a quantitative amount of the sample from the sample quantitative supply portion 157, thereby having a configuration in which such luminescent reagent and sample are mixed, and senses light from the mixed luminescent reagent and sample (hereinafter, referred to as "mixture"), thereby making it possible to sense an object of detection included in the sample.

According to an embodiment, the reagent supply portion 151 stores a luminescent reagent and quantitatively supplies the luminescent reagent to the sensor unit 159 through a reagent supply path.

In the embodiment of the present invention, the "reagent supply path" represents a component providing a space in which the luminescent reagent stored in the reagent supply portion 151 can move. For example, the fluid may be a pipe or the like having an inner space closed so as not to move the fluid.

According to an embodiment, the tube-type interlock pumps 153a, 153b, 153c may be disposed downstream of the reagent supply portion 151 on the reagent supply path, so that the reagent may be sucked from the reagent supply portion 151 to be supplied to the sensor unit 159 side, and the supply amount of the supplied luminescence reagent may be controlled.

For example, the tube-type interlock pumps 153a, 153b, 153c may supply a predetermined amount (hereinafter, referred to as "fixed amount") of the luminescent reagent from the reagent supply portion 151 to the sensor unit 159 for a predetermined time.

According to the present embodiment, the reagent supply unit 151 may be configured in plural. As shown in fig. 2, the reagent supply part 151 may include: a first reagent supply unit 151a for supplying a first reagent R1; a second reagent supply unit 151b for supplying a second reagent R2; and a third reagent supply unit 151c for supplying a third reagent R3. The first reagent supply portion 151a may be configured to supply the first reagent R1 at a first amount to the sensor unit 159; the second reagent supply unit 151b may be configured to supply the second reagent R2 at a second constant amount to the sensor unit 159; the third reagent supplying portion 151c may be configured to supply the third reagent R3 to the sample quantitative supply portion 157 at a third quantitative amount.

According to the present embodiment, the respective tube-type interlock pumps 153a, 153b, 153c are disposed on the respective reagent supply paths connected to the respective reagent supply portions 151a, 151b, 151c to control the amounts of reagents supplied from the respective reagent supply portions 151a, 151b, 151 c.

According to the present embodiment, the environmental pressure-inducing substance measurement device 150 according to an embodiment may further include a T-shaped pipe 161 located on the reagent supply path. The T-pipe 161 has a configuration that at least two fluids can be input and the received two fluids are mixed and output. T-pipe 161 is located downstream of tubing gang pumps 153a, 153b and upstream of sensor unit 159.

Further, the T-shaped pipe 161 may receive the output of the pipe-type interlock pump 151a and the output of the pipe-type interlock pump 151b to mix and output them with each other. The output of the T-pipe 161 is supplied to a sensor unit 159.

For example, as shown in fig. 2, the respective tube-type pumps 153a and 153b connected to the respective reagent supply units 151a and 151b through the T-shaped pipe 161 are connected, so that the reagents R1 and R2 output by the tube-type pumps 153a and 153b can be supplied to the sensor unit 159 in a mixed state. The reagent R3 output by the tube-type pump 151c can be supplied to the sample quantitative supply portion 157.

However, it is merely exemplary, and may be configured to mix only necessary reagents.

According to an embodiment, the first reagent R1, the second reagent R2, and the third reagent R3 are reagents having different functions, respectively, and the reagent supplied to the sensor unit 159 may be configured to include a mixture of one or more of the first reagent R1, the second reagent R2, or the third reagent R3. For example, the luminescence reagent supplied from the reagent supplying part 151 to the sensor unit 159 may be composed of a mixture including one or more of the first reagent R1 or the second reagent R2, and the luminescence reagent supplied from the reagent supplying part 151 to the sample quantifying part 157 may be composed of the third reagent R3.

According to an embodiment, the first reagent R1 is a luminescent reagent in a narrow sense as a compound that can be chemiluminescent, and the second reagent R2 and the third reagent R3 are composed of an activator that activates chemiluminescence of the first reagent R1.

According to an embodiment, the second reagent R2 may be composed of one of an oxidizing agent or a reducing agent that produces a chemiluminescent reaction with the first reagent R1 to make the first reagent R1 chemiluminescent.

According to an embodiment, the third reagent R3 may be composed of a basic compound or an acidic compound that produces a chemiluminescent reaction with the first reagent R1 to make the first reagent R1 chemiluminescent. For efficient reaction, it is preferably composed of a strongly basic compound or a strongly acidic compound. Further, the third reagent R3 may be supplied to the sample quantitative supply portion 157 to function as a carrier within the sample quantitative supply portion 157.

For example, any one of luminol (L uinol), lucigenin (L ucigenin), luciferin (L uciferin), Acridinium (Acridinium), oxalic acid (Oxalate), or ruthenium (ruthenium) may be used.

The sample quantitative supply portion 157 may receive a sample through a sample supply path and quantitatively supply the sample to the sensor unit 159.

The "sample supply path" is a component providing a space in which the sample received by the sample quantitative supply unit 157 can move. For example, the fluid may be a pipe or the like having an inner space closed so that the fluid can move without leaking.

According to an embodiment, the sample quantitative supply portion 157 may receive the sample specimen from the sample storage portion R disposed on the sample supply path. The tube-type interlock pump 153d may be disposed on the sample supply path in such a manner as to be connected to the sample storage portion R to suck the sample stored in the sample storage portion R to be supplied to the filter portion 155, and may control the supply amount of the sample supplied from the sample storage portion R to the filter portion 155.

According to the present embodiment, the ambient pressure-inducing substance measurement device 150 according to an embodiment may further include a filter unit 155 located on the sample supply path.

The filter portion 155 may be located upstream of the sample quantitative supply portion 157 on the sample supply path. The filter unit 155 filters the sample received from the sample storage unit R, and supplies the filtered sample (treated water) to the sample quantitative supply unit 157.

According to an embodiment, the filter part 155 may be composed of an absorbent resin column (resin column) including a Masking agent (Masking agent) or an extraction coil (extraction coil). The Masking agent (Masking agent) is a substance for filtering an interfering substance in the sample, which interferes with the chemiluminescent reaction between the substance to be detected and the luminescent reagent.

The filter unit 155 may remove an interfering substance in the sample with a Masking agent (Masking agent) or may perform filtering so as to extract only a substance to be detected.

A plurality of luminescent reagents may be used according to the kind of the environmental pressure-inducing substance to be detected, and the kind of the interfering substance that interferes with the reaction may be different depending on the luminescent reagent. The Masking agent (Masking agent) can be variously configured to be capable of labeling (targeting) and removing an interfering substance by the luminescent reagent, and thus more accurate and precise detection can be performed.

FIG. 6 is a table for explaining a luminescent reagent, an interfering substance, and a masking agent (Maskingagent) according to an object of detection. A specific example is explained below with reference to fig. 6.

Example 1) case where the object to be detected is Uric acid (Uric acid)

In order to detect Uric acid (Uric acid) corresponding to an environmental pressure-inducing substance in a sample, octylphenyl polyglycol ether (octylphenyl polyglycol ether) may be used as the first reagent R1, and potassium permanganate (KMnO) may be used as the luminescent reagent₄) As a second reagent R2, nitric acid (HNO)₃) Used as the third reagent R3. The substance interfering with the chemiluminescent reaction of the luminescent reagent with uric acid (uric acid) is Ascorbic acid (Ascorbic acid), and ferric ion (fe (iii)) which is one of the iron oxides may be used as a Masking agent (Masking agent) therefor.

Example 2) case where the object to be detected is divalent cobalt ion (Co (II))

In order to detect divalent cobalt ions (co (ii)) corresponding to the environmental pressure-inducing substance in the sample, luminol (L mininol) may be used as the first reagent R1, and hydrogen peroxide (H) may be used as the luminescent reagent₂O₂) As the second reagent R2, sodium hydroxide (NaOH) was used as the third reagent R3. The substance interfering with the chemiluminescent reaction of the luminescent reagent with the divalent cobalt ion (Co (II)) is ferric ion (Fe (III)), and Ascorbic acid (Ascorbic acid) can be used as a Masking agent (Masking agent) for this.

Example 3) case where the object to be detected was 1-glutamic acid (1-glutamic acid)

In order to detect 1-glutamic acid (1-glutamic acid) corresponding to an environmental stress-inducing substance in a sample, peroxyoxalate (peroxixlate) can be used as the first reagent R1 and hydrogen peroxide (H) can be used as the luminescent reagent₂O₂) As a second reagent R2, nitric acid (HNO)₃) Used as the third reagent R3. Substances interfering the chemiluminescent reaction of the luminescent reagent and 1-glutamic acid (1-glutamic acid) are monovalent potassium ions (K (I)) and divalent magnesium ions (Mg (II)), and Perylene (Perylene) can be used as a counterMasking agent for this (Masking agent).

The operation of the sample quantitative supply portion 157 will be described in detail below with reference to fig. 3.

Referring to fig. 3, the sample quantitative supply portion 157 is configured to supply a quantitative amount of a sample. For example, the six-way valve may be configured to be capable of quantitatively supplying the sample by changing the position a (position a) and the position b (position b). Hereinafter, the operation of the sample constant-volume supply unit 157 will be described assuming that the sample constant-volume supply unit 157 is constituted by a six-way valve.

The sample quantitative supply portion 157 includes a body B equipped with six ports P1, P2, P3, P4, P5, P6, into or out of which fluid can be input or output, and conduits L1, L2, L3, L4 here, the conduits L1, L2, L3, L4 are located outside the body B for communication between the ports or with an external path (or conduit).

The first tube L1 is a path for communicating the first port (or, also referred to as "sample-side port") P1 with a sample reagent path, specifically, an output of the filter section 155, the second tube L2 is a path for communicating the second port P2 with the fifth port P5, the third tube L3 is a path for communicating the third port (or, referred to as "sensor-side port") P3 with a sample reagent path, specifically, an input of the sensor unit 159, the fourth tube L4 is a path for communicating the fourth port with a carrier storage section (not shown), and the fifth tube L5 is a path for communicating the sixth port P6 with an exhaust section (not shown).

That is, the first tube L1 is used to input the sample output from the filter unit 155 to the first port P1, and the third tube L3 is used to input the sample output from the third port P3 to the sensor unit 159.

The pipes L1, L2, L3 and L4 do not always flow fluid, but are connected to ports in the body B such that a part of the pipes L1, L2, L3 and L4 flows fluid and the remaining part is blocked by no fluid flow.

In Position a, the body B is internally connected in such a manner that the first port P1 and the second port P2 communicate with each other, and is internally connected in such a manner that the fifth port P5 and the sixth port P6 communicate with each other. Here, the third port P3 and the second port P2 are not internally communicated with each other, and the fourth port P4 and the fifth port P5 are also not internally communicated with each other.

Further, for the purpose of explanation of the present invention, the case where the valve (not shown) is located at the Position that becomes Position a is referred to as the case where the sample constant-volume supply portion 157 is performing the constant-volume filling operation. The quantitative filling work is a work of quantitatively filling the sample specimen, and in the present embodiment, the sample specimen may be filled with, for example,

a second conduit L2.

In Position B, the main body B is internally connected in such a manner that the first port P1 and the sixth port P6 communicate with each other, and the second port P2 and the third port P3 communicate with each other, and the fourth port P4 and the fifth port P5 communicate with each other. Here, the third port P3 and the fourth port P4 are not internally communicated with each other, and the fifth port P5 and the sixth port P6 are also not internally communicated with each other.

Further, for the purpose of explanation of the present invention, the case where the valve (not shown) is located at the Position that becomes Position B is referred to as the case where the sample constant-volume supply portion 157 is performing the constant-volume supply operation. That is, the constant-volume supply operation is an operation of supplying the sample that is quantitatively filled in the constant-volume filling operation to the sensor unit 159.

In the Position a state (i.e., the constant-volume filling state), the sample supplied to the first pipe L1 by the tube-type gang 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, and the carrier is supplied to the sensor unit 159 through the fourth pipe L4, the fourth port P4, the third port P3, and the third pipe L3.

Immediately after the sample is discharged to the outside through the fifth duct L5, the state is switched to the Position B state (i.e., the constant-volume-supply operation state).

If the Position a is changed to the Position B, the sample supplied to the first conduit L1 by the tube-type interlock pump 153 is discharged to the outside through the first port P1, the sixth port P6, and the fifth conduit L5, and if the carrier is supplied to the fourth conduit L4, the sample filled in the second conduit by the carrier is supplied to the sensor unit 159 through the third port P3, specifically, if the carrier is supplied to the fourth conduit L4, the carrier is supplied to the sensor unit 159 through the fourth port P4, the fifth port P5, the second conduit L2, the second port P2, the third port P3, and the third conduit L3.

Here, if all the sample stored in the third duct L3 is supplied to the sensor unit 159, it is thereafter switched to the Position a state (i.e., the quantitative filling operation state).

In the manner described above, the switching operation is alternately performed as the Position a and the Position B to supply the sample to the sensor unit 159 in a fixed amount.

Fig. 4 is a diagram for explaining an exemplary structure of a sensor unit according to an embodiment of the present invention.

Referring to fig. 4, the sensor unit 159 includes: a flow cell (flow cell)152 that provides a space in which a luminescent reagent and a sample can be mixed with each other to perform a chemiluminescent reaction; the light detecting part 154 may sense light emitted by a chemiluminescent reaction.

According to an embodiment, the sensor unit 159 may be manufactured in a form of mounting the flow cell (flow cell)152 and the light detecting part 154 on a substrate of a flexible material such as an aluminum plate (aluminum plate).

The flow cell (flow cell)152 may be constituted by a reaction chamber 152a capable of accommodating a luminescent reagent and a sample specimen and having an internal space maintained airtight. The reaction chamber 152a is formed using a transparent material that can transmit light, and the other portion (hereinafter, referred to as a "light-opaque portion") than a portion through which light emitted from the internal space can be transmitted only through a portion of the reaction chamber 152a (hereinafter, referred to as a "light-transmitting portion") is surrounded by an opaque material.

The reaction chamber 152a may be formed of transparent glass, such as borosilicate, or transparent plastic, such as acrylic plastic, which is excellent in durability and transmittance.

According to an embodiment, the reaction chamber 152a may be surrounded by a material such as black PVC, which is opaque, to form a portion other than the light transmitting portion allowing light to transmit therethrough so that light cannot leak.

The light detecting section 154 is coupled to the flow cell (flow cell)152 in such a manner as to completely cover the light transmitting section allowing light to transmit in the reaction chamber 152 a.

According to an embodiment, a light inflow hole PMT hole capable of receiving light transmitted through a light transmitting portion of the reaction chamber 152a may be formed at the light detecting portion 154, and hermetically coupled to the flow cell 152 at a position corresponding to the light transmitting portion of the reaction chamber 152 a. Here, the light inlet hole is preferably configured as a light transmitting portion closely attached and joined to the reaction chamber 152a in a size that can completely cover the light transmitting portion of the reaction chamber 152a so that light flowing out of the light transmitting portion of the reaction chamber 152a is transmitted only to the light detecting portion 154.

According to an embodiment, the light detecting part 154 may include a converter that converts the intensity of the sensed light into an electrical signal and outputs it if the light flowing out is detected at the light transmitting part of the reaction chamber 152 a. The converter may be constituted by, for example, a photomultiplier Tube (PMT), a photomultiplier, a photodiode, or a phototransistor (Photo transistor).

That is, the light detection section 154 is a device that can receive light, i.e., light rays, and convert the light rays into an electrical signal, and may further include an element that amplifies the light and/or the electrical signal.

Referring to fig. 1, the water quality information measured by the ambient pressure-inducing substance measuring device 150 is an electric signal output from the light detecting unit 154, and the electric signal is transmitted to the computer 200. The computer 200 can analyze the characteristics of the electric signal to determine the degree of contamination of the sample.

For example, the computer 200 can know whether or not the sample contains the environmental pressure-inducing substance to be detected by comparing the intensity of the electric signal with a reference value (a value predetermined for the environmental pressure-inducing substance). The computer 200 can also determine the amount of the environmental pressure-inducing substance desired to be detected by analyzing how much the intensity of the electric signal is greater than the reference value.

The light-emitting reagent may be used in a variety of forms depending on the type of the environmental stress-inducing substance to be detected. Thus, the reference value may represent a value predetermined in accordance with the luminescent agent of the environmental pressure inducing substance.

Fig. 5 is a diagram for explaining the structure of a sensor unit according to another embodiment of the present invention.

Referring to fig. 5, the sensor unit 159 includes: a flow cell (flow cell)152 that provides a space in which a luminescent reagent and a sample can be mixed with each other to perform a chemiluminescent reaction; a plurality of light detecting portions 154a, 154b, 154c that can sense light emitted by a chemiluminescent reaction; and an optical wavelength separator 156.

Comparing the embodiment of fig. 5 with the embodiment described with reference to fig. 2 to 4, the embodiment of fig. 5 further includes an optical wavelength separator 156, and there is a difference in that the sensor unit 159 includes a plurality of optical monitoring portions. Hereinafter, the embodiment of fig. 5 will be described mainly in terms of differences.

According to the embodiment of fig. 5, the sensor unit 159 shown in fig. 5 is configured such that, when one or more compounds capable of chemiluminescence (a luminescence reagent in a narrow sense) is included in the luminescence reagent supplied from the reagent supply portion 151, a detection target according to the kind of the luminescence reagent can be confirmed.

Since the wavelength of the emitted light differs depending on the kind of the light-emitting reagent, when a plurality of light-emitting reagents are reacted in the flow cell (flow cell)152, light having different wavelengths is emitted.

The optical wavelength separator 156 is an optical element that receives optical signals including light having different wavelengths from each other and separates the light according to the wavelengths.

According to one embodiment, the optical wavelength separator 156 receives light emitted from the flow cell 152 and separates the light into wavelengths different from each other.

The optical wavelength separator 156 and the flow cell 152 are coupled so that the optical wavelength separator 156 does not allow the light emitted from the flow cell 152 to flow out to the outside but allows the light to flow into the optical wavelength separator 156.

The light having different wavelengths separated from the optical wavelength separator 156 is supplied to the plurality of light detectors 154a, 154b, and 154c, respectively.

Each of the light detectors 154a, 154b, and 154c is configured to be capable of independently receiving light of each wavelength separated by the optical wavelength separator 156 and detecting the light, and thereby can check a detection target according to the type of the luminescent reagent.

The operation and configuration of each of the plurality of light detection units 154a, 154b, and 154c in fig. 5 can be described with reference to fig. 2 to 4.

As described above, since it is understood that various modifications and variations can be made from the description in the above description by those having ordinary knowledge in the field to which the present invention pertains, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the scope of the claims but also by the scope equivalent to the scope of the claims.
