1 is a configuration diagram of a remote odor monitoring system according to an embodiment of the present invention, FIG. 2 is a conceptual diagram of the telemetry device shown in FIG. 1, and FIG. 3 is a view for explaining a sensing unit shown in FIG. 1.

The remote odor monitoring system according to an embodiment of the present invention may include an odor measuring device 200 and a server 300.

The odor measurement device 200 may be installed in an odor source that discharges odor gas such as a sewer manhole.

The odor measurement device 200 may measure the concentration of odor gas in the installed odor source and transmit it to the server 300.

The above-described odor measurement apparatus 200 may include a collection unit 50, a sensing unit 52, a control unit 54, and a communication unit 56.

The collecting unit 50 may collect air from an odor source that discharges odor gas, such as a sewer manhole.

For example, the collecting part 50 is a collecting pipe 60a, an air pump/blower 60, an air flow meter 62, and a mass flow controller as shown in FIG. 2. A (mass flow controller) 64, a first solenoid valve 66, a chamber 68, and a second solenoid valve 70 may be included.

It is preferable that the collection pipe 60a is installed to collect air (including odor gas) from the odor source. Collection pipe (60a) may be composed of a pipe.

The air pump/suction fan 60 guides air (including malodorous gas) flowing into the collection pipe 60a to the chamber 68 side.

The air flow meter 62 may measure the mass flow rate of a medium (ie, air) flowing through the collection pipe 60a and passing through the air pump/suction fan 60.

The air flow meter 62 may be installed at the rear end of the air pump/suction fan 60.

The mass flow controller 64 may be installed at the front end of the chamber 68.

The mass flow controller 64 may measure and control the amount of gas flowing into the chamber 68 through the collection tube 60a. That is, the amount of air collected in the chamber 68 by the mass flow controller 64 can be checked.

The first solenoid valve 66 is installed at the front end of the chamber 68 (ie, between the mass flow controller 64 and the chamber 68), and the second solenoid valve 70 is at the rear end of the chamber 68 (ie , It may be installed between the chamber 68 and the intake manifold 72).

The first solenoid valve 66 and the second solenoid valve 70 perform an opening or shutting operation under the control of the controller 54.

Here, the first solenoid valve 66 and the second solenoid valve 70 will operate opposite to each other.

The chamber 68 substantially collects air (eg, including odor gas) introduced through the collection pipe 60a. Chamber 68 may be a vacuum chamber.

For example, while introducing air into the chamber 68, the first solenoid valve 66 will be open and the second solenoid valve 70 will be shut off. Conversely, after the air is sufficiently introduced (collected) into the chamber 68, the first solenoid valve 66 will be shut off and the second solenoid valve 70 will be opened.

The sensing unit 52 may measure the odor gas by sensing the air collected by the collecting unit 50.

For example, the sensing unit 52 may analyze malodorous substances as illustrated in Table 1 below in order to measure malodorous gas.

Methyl isobutyl ketone, butyl acetate, i-butyl alcohol

The sensing unit 52 may include intake manifolds 72 and a sensor array module 74.

In the sensor array module 74, as illustrated in FIG. 3, a plurality of sensor modules 74a to 74n are arranged in a matrix form.

One intake manifold 72 is connected to each of the sensor modules 74a to 74n.

Accordingly, the air in the chamber 68 may be introduced to each of the sensor modules 74a to 74n through the respective intake manifolds 72.

Each of the sensor modules 74a to 74n may include a plurality of sensors to analyze a plurality of types of malodorous substances (eg, 22 types of designated malodorous substances illustrated in Table 1).

That is, as illustrated in FIG. 3, each of the sensor modules 74a to 74n includes a plurality of sensors formed in one bundle.

For example, each of the sensor modules 74a to 74n may _{include various sensors such as an NH 3} sensor, an H ₂ S sensor, a VOC _S sensor, and a MOS sensor.

Accordingly, each of the sensor modules 74a to 74n may _{measure the concentration by sensing ammonia (NH 3} ), hydrogen sulfide (H ₂ S), VOC _S , MOS, and the like.

As a result, the sensing unit 52 measures the odor gas in each sensor module 74a to 74n, and transmits the measured result (eg, the type and concentration of odor gas) to the control unit 54.

In this way, when measuring with several sensor modules 74a to 74n, it is possible to reduce a measurement error due to a manufacturing error of the sensor itself. If only a single sensor is used, when a measurement error occurs due to a manufacturing error in a single sensor, the measurement value of the single sensor is used as it is, and there is a problem. However, if several sensors are measured with a sensor module as a bundle, the average value of them can be used, so that measurement errors due to manufacturing errors of the sensors themselves can be minimized.

In other words, it is possible to minimize the measurement error of the sensing unit 52 by multiplexing the sensor modules 74a to 74n in a matrix form.

The communication unit 56 may transmit data of odor gas (eg, type, concentration, intensity, etc. of odor gas) to the server 300 under the control of the control unit 54.

For example, the communication unit 56 may transmit data of odor gas to the server 300 by wire or wirelessly. In the case of wired communication, RS-485/422, Ethernet, etc. can be used. In the case of wireless communication, LTE, Zigbee, BlueTooth, etc. can be used.

The control unit 54 controls the overall operation of the odor measurement device 200.

The control unit 54 controls air to be collected periodically or at the request of a user, and when air collection is complete, it may perform an odor determination, or the like.

That is, the control unit 54 compares the data of the odor gas measured by the sensing unit 52 (for example, data on the concentration of the odor gas) with a preset reference value to determine whether or not odor is generated, and when the odor occurs, corresponding information (Eg, the concentration of odor gas) can be controlled to be transmitted to the server 300.

In other words, the control unit 54 may analyze the concentration of the malodorous gas measured by the sensing unit 52, and has a reference value for evaluating the concentration of the malodorous gas in advance. In addition, the control unit 54 compares the concentration of the odor gas measured by the sensing unit 52 (more specifically, the sensor modules of the sensor array module 74) with a preset reference value to determine whether or not odor is generated or not. I can.

At this time, the control unit 54 may determine whether or not the odor gas is generated based on the odor determination degree according to the direct sensory method as shown in Table 2 below.

Degree of odor Odor tool Explanation 0 Odorless
(None) Relatively odorless, in a state in which nothing is sensed by the sense of smell. One Detect smell
(Threshold) You don't know what it's smelling, but it's in a state where you can feel the smell 2 Moderate smell
(Moderate) The state of knowing what it smells like 3 Strong smell
(Strong) It refers to a strong smell that can be easily detected, for example, the smell of cresols in a hospital. 4 An excruciating smell
(Very Strong) Very strong odor, for example a severe smell from conventional toilets in the summer 5 Unbearable smell
(Over Strong) An intense odor that is difficult to bear, which makes you feel as if your breathing will stop.

Here, the preset reference value may be, for example, that the degree of odor (i.e., intensity of odor) is 2.5 stages (ie, an intermediate stage between the degree of odor 2 and the degree of odor 3).

If necessary, the controller 54 may reflect information from an external environment sensing unit (not shown) in determining whether or not an odor is generated or not.

A more detailed description of the control unit 54 will be described later.

FIG. 4 is a flowchart illustrating a control algorithm of the air pump/suction fan and the first and second solenoid valves in the control unit 54 of the odor measuring apparatus shown in FIG. 1.

First, the control unit 54 of the odor measurement device 200 receives a collection operation signal (S10). Here, the collecting operation signal may be generated periodically or may be generated at the request of a user.

Subsequently, the controller 54 operates the air pump/suction fan 60 to collect air and opens the first solenoid valve 66 (S12).

Accordingly, air from the odor source is introduced into the chamber 68 through the collection pipe 60a installed near the odor source through which odor gas is discharged, such as a sewer manhole. At this time, the control unit 54 checks the amount of air collected in the chamber 68 through the mass flow controller 64 (S14).

If the amount of air collected in the chamber 68 is not sufficient ("No" in S16), the control unit 54 returns to the above-described step S12 and controls the operation from that step to continue.

Conversely, if the amount of air collected in the chamber 68 is sufficient ("Yes" in S16), the control unit 54 stops the operation of the air pump/intake fan 60 and blocks the first solenoid valve 66 (S18). ).

Then, the control unit 54 opens the second solenoid valve 70 (S20).

Accordingly, the air collected in the chamber 68 moves to the sensor array module 74 through the intake manifold 72 (S22). That is, the air collected by the collecting unit 50 moves to the sensing unit 52.

FIG. 5 is a flowchart illustrating a method of measuring malodor in the malodor measuring apparatus shown in FIG. 1.

As described above, when the air collected by the collecting unit 50 moves to the sensing unit 52 (S30), the sensing unit 52 senses the air collected by the collecting unit 50 to measure the odor gas. (S32). At this time, the sensor array module 74 of the sensing unit 52 includes a plurality of sensor modules in the form of a matrix, and each sensor module includes a plurality of different sensors as a bundle. Each sensor module can measure the concentration of odor gas.

In this way, each of the sensor modules 74a to 74n of the sensing unit 52 transmits the measurement result (eg, concentration of odor gas) to the control unit 54 (S34).

For example, it is assumed that there are three sensor modules of the sensing unit 52, and each sensor module _{senses only ammonia (NH 3} ) and transmits a concentration value corresponding thereto. In this case, for example, sensor module 1 may _{transmit data indicating that 5 ppm of ammonia (NH 3} ) was measured to the control unit 54, and sensor module 2 _{measured 4} ppm of ammonia (NH 3 ). Meaningful data may be transmitted to the controller 54, and the sensor module 3 may transmit _{data indicating that 4.5 ppm of ammonia (NH 3} ) was measured to the controller 54.

Of course, in the above example, the three sensor modules have been _{described assuming that only ammonia (NH 3} ) is sensed, but the three sensor modules have other gases (e.g., hydrogen sulfide (H ₂ S), VOC _S , MOS, etc.) You can also sense it. Accordingly, the three sensor modules in the above example can transmit _{not only measured concentration data for ammonia (NH 3} ) but also measured concentration data for hydrogen sulfide (H ₂ S), VOC _S , MOS, etc. to the control unit 54 Is of course.

The control unit 54 calculates an average value of the concentrations of odor gases measured by each sensor module (S36). In other words, in the previous step S34, the control unit 54 is the three measurement concentration data from the sensing unit 52 (ammonia (NH ₃ ): 5 ppm, ammonia (NH ₃ ): 4 ppm, ammonia (NH ₃ ): 4.5 ppm) ) Has been received, so the average value of the received three measured concentration data is calculated. That is, the control unit 54 may calculate that the average value of the concentrations of the odor gas (eg, ammonia (NH _{3 )) measured by the sensing unit 52 is 4.5 ppm.}

In this way, the control unit 54 may calculate the average value of the concentration data of the odor gas measured by the plurality of sensor modules 74a to 74n and use it as a basis for determining whether or not the odor has occurred. If only a single sensor is used, even if a measurement error due to a manufacturing error occurs in a single sensor, the control unit 54 uses the measured value of the single sensor as it is. However, if several sensors are measured by a sensor module in a bundle, the control unit 54 can use the average value of them, so that measurement errors due to manufacturing errors of the sensors themselves can be minimized. As a result, the reliability of the measurement result and the reliability of the judgment of occurrence of odor can be increased.

Subsequently, the control unit 54 determines whether the calculated odor concentration (ie, the average value of the odor concentrations of each sensor module) is equal to or greater than a preset reference value (S38). Here, as for the preset reference value, for example, in the case of ammonia (NH ₃ ), 1 ppm may be referred to as a reference value (reference concentration), and the odor intensity (ie, odor degree) at this time may correspond to 2.5 steps. If necessary, the reference value is adjustable. Here, the marked odor is classified according to the direct sensory method in Table 2. It is also possible to express the odor concentration using a odor concentration classification method other than the direct sensory method. On the other hand, since the sensing unit 52 (more specifically, the sensor array module 74) can measure two or more kinds of malodorous gases, if the concentration of each of two or more kinds of malodorous gases is measured, the control unit 54 is It will be determined whether the average value of the concentration of the complex odor is equal to or greater than the preset reference value with a preset reference value corresponding to.

If the calculated odor concentration (that is, the average value of odor concentrations of each sensor module) is less than a preset reference value ("No" in S38), the control unit 54 determines that odor has not occurred and returns to step S32. And repeat the operation from that step.

On the contrary, if the calculated odor concentration (that is, the average value of odor concentrations of each sensor module) is more than a preset reference value ("Yes" in S38), the controller 54 determines that odor has occurred, and the odor occurrence notification and the corresponding odor concentration, The intensity of odor is notified to the server 300 through the communication unit 56 (S40). Here, the odor concentration known to the server 300 is the odor concentration calculated by the control unit 54, and will be an average concentration of odor gases of each sensor module.

In the above description, only when the odor concentration calculated by the control unit 54 is greater than or equal to a preset reference value, the odor occurrence notification and the corresponding odor concentration and odor intensity are notified to the server 300 through the communication unit 56. Accordingly, the control unit 54 may transmit the calculated odor concentration directly to the server 300 without comparison with the reference value.

6 and 7 are diagrams for schematically explaining the operation of the server 300 shown in FIG. 1.

The server 300 may estimate the degree of water pollution in the sewage pipe network based on information (eg, concentration) of odor gases in odor sources in which each odor measurement device 200 is installed. In other words, as shown in FIG. 6, the odor measuring device 200 may be installed for each point (A1 to A20), and the odor measuring device 200 includes information on the odor gas for each point (A1 to A20). May be transmitted to the server 300. Accordingly, the server 300 accumulates information (e.g., concentration) of odor gas from each odor measurement device 200 to convert it into big data, and estimates the degree of water pollution in the sewage pipe network through the accumulated big data. have.

In this way, the server 300 stores the odor data (eg, the concentration of the odor gas) measured by the odor measurement device 200 for each point (A1 to A20) and can be used as big data later, so that the odor source If the occurrence is repetitive, the cause can be easily identified based on previous data.

In addition, the server 300 estimates the cause of the odor and the place where the odor is generated based on the odor data (e.g., the concentration of the odor gas) measured by the odor measurement device 200 for each point (A1 to A20). And can be traced. In other words, as shown in FIG. 7, the server 300 checks the odor concentration of each point (A1 to A20) and checks the odor concentration of each point (eg, A3, A4, A11 to A13, A17 to A20). It is possible to estimate and track the approximate place where the odor is generated by grouping (G1, G2) around the point with the highest odor concentration. That is, the server 300 estimates the cause of the odor and the location of the odor according to the concentration and ratio of the odor gas (eg, ammonia, hydrogen sulfide, etc.) measured by the odor measurement device 200 at each point (A1 to A20). And can be traced. At this time, the server 300 may utilize the flow of sewage between adjacent points to track the place where the odor occurs.

8 is an internal configuration diagram of the server 300 shown in FIG. 1. The server 300 may be an example of an odor remote monitoring device described in the claims of the present invention.

The server 300 includes a receiving unit 80, a comparison unit 82, a grouping unit 84, an alignment unit 86, a determination unit 88, a notification unit 90, a data storage unit 92, and a control unit ( 94).

The receiving unit 80 may receive odor data (eg, odor concentration) from the odor measurement device 200. That is, since the odor measurement device 200 is installed at each point of the sewer network (eg, near a sewer manhole), the receiving unit 80 may receive the concentration of odor at each point.

Here, the odor concentration received by the receiving unit 80 will receive only the odor concentration of the odor measuring device 200 in which the odor concentration measured by the odor measuring device 200 is equal to or higher than the reference value preset in the odor measuring device 200. . Of course, if necessary, the receiving unit 80 may receive the odor concentration in the odor measuring device 200 at all points of the sewage pipe network regardless of the reference value preset in the odor measuring device 200.

In other words, the receiving unit 80 receives only the odor concentration from the odor measurement device 200, which is determined to be odor generation, among the odor measurement devices 200 at all points of the sewage pipe network, or receives the odor at all points regardless of the odor generation determination. The odor concentration measured by the measurement device 200 may be received.

The comparison unit 82 compares the concentration of odor at each point with a preset reference value. Here, as the preset reference values, there may be a single reference value for each odor gas and a reference value for each complex odor. Therefore, for example, if the odor gas at each point is ammonia (NH ₃ ), the comparison unit 82 compares the odor concentration at each point and a preset reference value for the corresponding odor gas (ie, ammonia). If the odor concentration at each point is the concentration of a complex odor in which two or more odor gases are combined, the comparison unit 82 compares the odor concentration at each point (that is, the concentration of the complex odor) with a preset reference value of the corresponding complex odor. do.

If necessary, the reference value used in the comparison unit 82 is adjustable.

The grouping unit 84 may group the periphery of points having a maximum value or a value equal to or higher than the reference value among points having an odor concentration equal to or higher than a preset reference value according to a comparison result of the comparison unit 82. In this case, the grouping unit 84 is preferably grouped based on points having an odor concentration greater than or equal to a preset reference value according to the comparison result of the comparison unit 82. That is, points having an odor concentration less than a preset reference value are not included in the grouping operation.

The alignment unit 86 arranges the odor concentration at each point in order of size. That is, the alignment unit 86 sorts the malodor concentrations of points having a malodor concentration equal to or greater than a preset reference value according to the comparison result of the comparison unit 82 in order of size.

The determination unit 88 may determine the odor occurrence point based on the sewage flow between adjacent points and the odor concentration for each grouped point. That is, since the flow direction of the sewage helps to spread the odor, the determination unit 88 uses the sewage flow between adjacent points to determine the odor occurrence point. For example, the determination unit 88 is based on the sewage flow and the odor concentration of each grouped point, the odor concentration of the point having the highest value and the next rank (eg, the highest value among values lower than the highest value). It can be identified as the point of occurrence of odor between the points of.

The notification unit 90 may inform the outside of the odor generation point determined by the determination unit 88 and the degree of contamination according to the odor concentration at the corresponding odor generation point.

The data storage unit 92 may store odor data for each point received through the reception unit 80 (eg, type, concentration, intensity, etc. of odor gas) and information on the odor occurrence point from the determination unit 88. have.

The control unit 94 controls the overall operation of the server 300.

In particular, the control unit 94 can track the odor occurrence point based on the information stored in the data storage unit 92, and if necessary, the odor occurrence point tracking location information (that is, location information tracking the odor occurrence point). ) Can be transmitted to the outside through the notification unit 90.

9 is a flowchart illustrating a method for remotely monitoring odors according to an embodiment of the present invention, and FIG. 10 is a diagram illustrating an example of a sewage pipe network employed in the description of FIG. 9.

In the following description, as illustrated in FIG. 10, it is assumed that an odor generating source (an odor generating point) exists between the point A15 and the point A16. In addition, it is assumed that the odor concentration measured by the odor measurement device 200 is the odor concentration for ammonia (NH _{3 ).} In addition, it is assumed that the odor concentration at the point A8 is 2 ppm, the odor concentration at the point A15 is 6 ppm, and the odor concentration at the point A16 is 7 ppm.

First, the server 300 receives the odor concentration at the corresponding point from each odor measurement device 200 (S50). In particular, the received odor concentration will receive only the odor concentration of the odor measuring device 200 in which the odor concentration measured by the odor measuring device 200 is equal to or higher than a predetermined reference value among the respective odor measuring devices 200. In other words, as illustrated in FIG. 10, the number of points is all 20, but the malodor concentration value among the 20 points is the malodor measuring device 200 measuring the malodor concentration equal to or higher than the reference value preset in the corresponding malodor measuring device 200. ) Will only receive odor concentrations.

Here, the odor concentration at the point A8, the point A15, and the point A16 is greater than or equal to a preset reference value in the corresponding odor measurement device 200, so that the server 300 is the point A8, the point A15 ), and the malodor concentration at point A16.

Alternatively, since the odor measurement device 200 may directly transmit the calculated odor concentration to the server 300 without comparison with a preset reference value, in this case, the server 300 is the odor of all points (A1 to A20). It can be seen that it receives the concentration.

Subsequently, the server 300 determines whether the received odor concentrations are equal to or greater than a reference value preset in the server 300 (S52). In this case, 1 ppm may be set in the server 300 as a reference value (ie, reference concentration) for ammonia.

If the received odor concentration is less than the preset reference value ("No" in S52), the server 300 returns to the above-described step S50 and repeats the operation from that step.

Conversely, in the case of FIG. 10, all of the odor concentrations at points A8, A15, and A16 are more than a preset reference value, and among the odor concentrations at the points A8, A15, and A16 received as described above. If there is an odor concentration equal to or higher than the preset reference value ("Yes" in S52), the server 300 groups the periphery of the point A16 having the highest value among points having an odor concentration equal to or higher than the preset reference value (S54). That is, as shown in FIG. 10, the server 300 may create a group G3 including a point A8, a point A15, and a point A16.

Subsequently, the server 300 sorts the odor concentrations of the grouped points A8, A15, and A16 in order of size (S56). Thereby, the order will be 1) A16 (7ppm), 2) A15 (6ppm), 3) A8 (2ppm).

Then, the server 300 determines the odor generation point (ie, the odor source) based on the sewage flow between adjacent points and the odor concentration for each point (S58, S60). For example, if the flow direction of sewage is the same as A8 -> A16 -> A15, as shown in FIG. 10, the server 300 considers the flow of sewage and the point between the point A16 and the point A15 It can be discriminated (estimated) that there is an odor generating point (an odor generating source) close to (A16). In addition, the server 300 can estimate that the odor measurement concentration at the point A8 is low and the odor measurement concentration at the point A15 is similar to that of the point A16 due to the effect of the flow of sewage.

Accordingly, the server 300 notifies the determined odor generation point (odor generation source) and the degree of contamination according to the odor concentration of the odor generation point to the outside (S62).

In addition, the server 300 uses data of odor gas for each point received through the receiving unit 80 (eg, type, concentration, intensity, etc. of odor gas) and information on the odor occurrence point as big data at a later time. It is stored for (S64). The server 300 may track the odor occurrence point based on the stored information, and, if necessary, transmit information on the odor occurrence point tracking location information to the outside through the notification unit 90.

In FIGS. 9 and 10 described above, the measurement of ammonia was described as an example, but all gases measured by a sensor module capable of detecting 22 types of designated odor substances such as _{H 2 S, VOCs, and MOS with a similar algorithm} ) Can also be applied to the concentration measurement.

Meanwhile, a remote odor monitoring method according to an embodiment of the present invention will be described with reference to FIG. 11. 11 is a view showing another example of a sewage pipe network employed in the description of FIG. 9.

In the following description, it is assumed that an odor generating source (ie, an odor generating point) exists between the point A14 and the point A17 as illustrated in FIG. 11. In addition, it is assumed that the odor concentration measured by the odor measurement device 200 is the odor concentration for ammonia (NH _{3 ).} In addition, it is assumed that the odor concentration at the point A2 is 1.5 ppm, the odor concentration at the point A13 is 2 ppm, the odor concentration at the point A14 is 6 ppm, and the odor concentration at the point A17 is 5 ppm.

First, the server 300 receives the odor concentration at the corresponding point from each odor measurement device 200 (S50). In particular, the received odor concentration will receive only the odor concentration of the odor measuring device 200 in which the odor concentration measured by the odor measuring device 200 is equal to or higher than a predetermined reference value among the respective odor measuring devices 200. In other words, as illustrated in FIG. 11, the number of points is 20, but the malodor concentration value among the 20 points is the malodor measuring device 200 measuring the malodor concentration equal to or higher than the reference value set in the corresponding malodor measuring device 200. You will receive only the odor concentration of ).

Here, the odor concentration at the point A2, the point A13, the point A14, and the point A17 is greater than or equal to a preset reference value in the corresponding odor measurement device 200, so that the server 300 is at the point A2 ), point A13, point A14, and point A17 can be considered to receive the odor concentration.

Alternatively, since the odor measurement device 200 may directly transmit the calculated odor concentration to the server 300 without comparison with a preset reference value, in this case, the server 300 is the odor of all points (A1 to A20). It can be seen that it receives the concentration.

Subsequently, the server 300 determines whether the received odor concentrations are equal to or greater than a reference value preset in the server 300 (S52). In this case, 1 ppm may be set in the server 300 as a reference value (ie, reference concentration) for ammonia.

If the received odor concentration is less than the preset reference value ("No" in S52), the server 300 returns to the above-described step S50 and repeats the operation from that step.

On the contrary, in the case of FIG. 11, all of the odor concentrations at the points A2, A13, A14, and A17 are equal to or higher than a preset reference value. Among the odor concentrations in A17), if there is an odor concentration higher than the preset reference value ("Yes" in S52), the server 300 groups the vicinity of the point A14 having the highest value among points having the odor concentration higher than the preset reference value. Do it (S54). That is, as shown in FIG. 11, the server 300 may create a group G4 including a point A2, a point A13, a point A14, and a point A17.

Subsequently, the server 300 sorts the odor concentration of each grouped point (A2, A13, A14, A17) in order of size (S56). Thereby, 1) A14 (6ppm), 2) A17 (5ppm), 3) A13 (2ppm), 4) A2 (1.5ppm).

Then, the server 300 determines the odor generation point based on the sewage flow between adjacent points and the odor concentration for each point (S58, S60). For example, if the flow direction of sewage is the same as A17 -> A14 -> A13, A14 -> A2, as shown in FIG. Between A14), it can be determined (estimated) that the odor occurrence point (or odor source) has occurred near the point A17. In addition, the server 300 may estimate that the points A2 and A13 are spread of odors according to the flow of sewage.

Accordingly, the server 300 notifies the determined odor generation point (odor source) and the degree of contamination according to the odor concentration of the odor generation point to the outside (S62).

In addition, the server 300 uses data of odor gas for each point received through the receiving unit 80 (eg, type, concentration, intensity, etc. of odor gas) and information on the odor occurrence point as big data at a later time. It is stored for (S64). The server 300 may track the odor occurrence point based on the stored information, and, if necessary, transmit information on the odor occurrence point tracking location information to the outside through the notification unit 90.

In FIGS. 9 and 11 described above, ammonia measurement has been described as an example, but all gases measured by a sensor module capable of detecting 22 types of designated odor substances such as _{H 2 S, VOCs and MOS with a similar algorithm} ) Can also be applied to the concentration measurement.

In addition, the above-described method for remote odor monitoring of the present invention can be implemented as a computer-readable code on a computer-readable recording medium. The computer-readable recording medium includes all types of recording devices that store data that can be read by a computer system. Examples of computer-readable recording media include ROM, RAM, CD-ROM, magnetic tapes, floppy disks, and optical data storage devices. In addition, the computer-readable recording medium is distributed over a computer system connected through a network, so that computer-readable codes can be stored and executed in a distributed manner.
