The user terminal 300 may correspond to a terminal of a user receiving tap water or a terminal of a person related to the user.

That is, the processor 120 of the analysis server 100 may deliver the necessary message to the user or related person through the user terminal 300.

Figure 2 is a flowchart showing the process of determining the state of tap water inside the distribution pipe 210 according to an embodiment of the present invention.

Figure 3 is a diagram showing the specific configuration of the water metering device 200 according to an embodiment of the present invention.

As can be seen in FIG. 3 , the water metering device 200 can receive power through the constant power source 250 and can also receive tap water from the distribution pipe 210.

The water metering device 200 is a device that supplies tap water to households included in a specific zone. When there are multiple zones, there may also be a plurality of water metering devices 200.

In addition, the water metering device 200 can deliver tap water to each home through a plurality of water supply pipes 230, and includes at least a first measurement sensor 270 and a second measurement sensor 280. A measurement sensor may be installed in the distribution pipe 210.

Meanwhile, in a state where the first measurement sensor 270 and the second measurement sensor 280 are testing the quality of tap water inside the distribution pipe 230, the first measurement sensor 270 is connected to a plurality of water supply pipes 230. ), it may be located at the same height or lower than the water supply pipe located at the lowest level.

Additionally, the second measurement sensor 280 may be located at the same height as or higher than the water supply pipe located at the top among the plurality of water supply pipes 230.

In this situation, the water metering device 200 may acquire water quality data about the tap water inside the distribution pipe 210 through the first measurement sensor 270 and the second measurement sensor 280 (S210).

Next, the water metering device 200 determines the state of tap water inside the distribution pipe 210 based on the water quality data acquired through the first measurement sensor 270 and the second measurement sensor 280 (S220). You can.

The first measurement sensor 270 and the second measurement sensor 280 may be installed at different positions (heights), and their measurement ranges may also be set to be different. This will be described later with reference to Figure 4.

Meanwhile, the water metering device 200 can transmit the water quality data to the analysis server through long-distance communication using one communication module 220. A plurality of measurement sensors including various sensors such as the first measurement sensor 270, the second measurement sensor 280, and the meter 240 can correspond to the one communication module 220, and the water metering device 200 ) can transmit a plurality of water quality data to the analysis server 100 through long-distance communication through one communication module. In other words, it is a 1 to N method. For reference, the communication module 220 included in the water metering device 200 may include a type of transmitter or receiver.

Additionally, the transmitter of the water metering device 100 may transmit collected data (meter reading data, water quality data, etc.) to the analysis server 100 using RS-485 (serial communication). Here, the RS-485 serial communication method may refer to a communication method that sequentially transmits and receives data 1 bit at a time through a transmission line.

According to an embodiment of the present invention, when the communication module 220 of the water metering device 200 does not receive separate data from the analysis server 100, the collected data is transmitted to the analysis server ( 100).

In other words, the water metering device 200 and the analysis server 100 cannot transmit or receive data at the same time, and when one side transmits, the other side can only receive data. Additionally, after receiving information from the analysis server 100, the water metering device 200 may transmit data to the analysis server 100 after a certain period of time (waiting time, timeout) has elapsed. This is to prevent information loss by transmitting information from both sides simultaneously.

In addition, according to an embodiment of the present invention, the water metering device 200 is capable of collecting information from a plurality of measurement sensors and a plurality of meters through RS-485 communication, and transmits this information through one communication module. Communication can be performed with the analysis server 100. At this time, communication between the communication module 220 of the water metering device 200 and the analysis server 100 includes IoT, Wi-Fi, Wideband CDMA (WCDMA), High Speed Downlink Packet Access (HSDPA), and High Speed Downlink Packet Access (HSDPA).

For reference, among the plurality of measuring sensors and plurality of meters included in the water metering device 200, one device is a kind of main device and can transmit commands to each of the other devices corresponding to sub devices.

Meanwhile, the existing water metering device required periodic battery replacement, and the existing water metering device itself was buried underground, making real-time inspection (flooding, water leakage, hygiene issues, meter reading) difficult.

In order to solve the above problem, the water metering device 200 of the present invention can be installed on the ground or underground, and the necessary power can be supplied through the constant power source 250.

In addition, the water metering device 200 may include a solar power device, a solar power device, a wind power device, a geothermal device, etc., and may provide power through the constant power source 250 such as the solar power device, a solar power device, a wind power device, a geothermal device, etc. can be supplied.

Through this, the water metering device 200 can operate stably even if a specific power supply source is inoperable by diversifying power supply sources.

The analysis server 100 allows the water metering device 200 to acquire water quality data on tap water in real time using a plurality of measurement sensors including the first measurement device 270 and the second measurement device 280. there is.

Meanwhile, a plurality of measuring sensors including the first measuring sensor 270 and the second measuring sensor 280 measure the pH concentration that measures the activity of hydrogen ions (i.e., hydrogen ion concentration index (pH)) present in tap water. A detection sensor, a turbidity detection sensor that optically measures the degree of scattering by suspended substances by incident light on tap water, a residual chlorine concentration detection sensor that measures the concentration of chlorine remaining during disinfection to remove pathogenic bacteria in tap water, It may include at least one measurement sensor among an EC (electric conductivity) conductivity detection sensor and a water temperature detection sensor. For reference, the data measured by the first measurement sensor 270 and the second measurement sensor 280 may be of the same type (ex. PH, etc.), and only the measurement range may be different (described later).

Among the sensors, the EC conductivity detection sensor is also abbreviated as CTD and represents electrical conductivity, temperature, and depth. In addition, the general CTD equipment equipped with the EC conductivity detection sensor is a device that can simultaneously measure water temperature and salinity by water depth in the field.

Therefore, when the EC conductivity detection sensor is adopted as the water quality sensor in the present invention, it is possible to detect the chlorine concentration and water temperature contained in tap water without installing a separate residual chlorine concentration detection sensor and water temperature detection sensor. By measuring electrical conductivity and water pressure, salinity can be calculated from electrical conductivity and water pressure, excluding water depth, since it is installed on the distribution pipe side.

Here, when using the CTD as the water quality sensor, regular calibration of the sensor is required, and depending on the purpose of investigation, in addition to the EC conductivity detection sensor, dissolved oxygen (DO), pH, and light transmission Various detection sensors such as the like can also be used by being detachably mounted at the entrance of the distribution pipe 210.

In addition, the water quality sensor may include installing and using a water pressure detection sensor, water leak detection sensor, vibration detection sensor, earthquake detection sensor, etc. in addition to the above detection sensors.

Specifically, the present invention provides water quality data for tap water inside the distribution pipe 210 obtained through the plurality of measurement sensors, including at least one of pH concentration, turbidity, residual chlorine concentration, electrical conductivity, and water temperature. can do.

At this time, the electrical conductivity of the tap water is the formula below at a standard temperature of 25 degrees

formula)

It can be calculated by .

Here, C ₂₅ is the electrical conductivity value at 25 degrees, Ct is the electrical conductivity value at t degrees, and α may correspond to the linear temperature coefficient.

Specifically, α can be selected from 0 to 5% per ℃, and is usually about 2% per ℃. In general, the linear temperature coefficient is smaller for acids (ex 1.6%), and can be larger for bases (ex 2.2%).

The processor 120 of the analysis server 100 sends a warning message to the user terminal 300 of each household to which the tap water is delivered when the electrical conductivity value (based on 25°C) measured by the measurement sensor for the tap water is higher than the contamination standard value. You can prohibit its use by sending .

For reference, the pollution standard value may vary depending on the point at which tap water is delivered. Specifically, for places where pollution is more critical, such as schools and hospitals, the pollution standard value may be higher than other locations (e.g. factories).

Additionally, the water metering device 200 may transmit a plurality of meter reading data obtained from a plurality of meters 240 to the analysis server 100 through long-distance communication through the communication module 220. The analysis server 100 may store the received meter reading data (tap water usage, etc.) in the database 130.

That is, the analysis server 100 may receive water quality data from the water metering device 200 based on long-distance communication and store it in the database 130. Here, water quality data may include the amount of tap water used, the degree of contamination of tap water, and the electrical conductivity of tap water.

Figure 4 is a diagram schematically showing the state of tap water according to the measurement range and section of a plurality of measurement sensors according to an embodiment of the present invention.

The measurable range of the first measurement sensor 270 corresponds to the range between the minimum value of the 1-1 point 310 and the maximum value of the 1-2 point 320, and the measurement of the second measurement sensor 280 It can be set that the possible range corresponds to the range between the 2-1st point (330), which is the minimum value, and the 2-2th point (340), which is the maximum value.

At this time, if the 1-1 point 310 is less than or equal to the 2-1 point 330, the 1-2 point 320 is greater than or equal to the 2-1 point 330. It may be smaller than or equal to the 2-2 point 340 (FIG. 4A).

Additionally, when the 2-1 point 330 is less than or equal to the 1-1 point 310, the 2-2 point 340 is greater than or equal to the 1-1 point 310. It may be less than or equal to the 1-2 (320) point (FIG. 4b).

That is, as can be seen in FIG. 4(a)(b), the measurement range of the first measurement sensor 270 and the measurement range of the second measurement sensor 280 are in an overlapping area (point 2-1 to point 1-2). points or points 1-1 to 2-2, and may be different from each other. As will be described later, the overlapping area may correspond to a normal section for the measurement element.

The water metering device 200 determines the state of tap water inside the distribution pipe 210 based on water quality data acquired through the first measurement sensor 270 and the second measurement sensor 280 having the measurement ranges. can be judged.

In other words, the water metering device 200 can distinguish the water quality data of the tap water inside the distribution pipe 210 into a normal state and an abnormal state according to the measurement range of the first measurement sensor 270 and the second measurement sensor 280. .

Specifically, in a state where the 1-1 point 310 is smaller than or equal to the 2-1 point 330 (FIG. 4a), the values obtained through the first measurement sensor 270 and the second measurement sensor 280 The water quality data may be greater than or equal to the 2-1 point 330 and less than or equal to the 1-2 point 320. By setting the section as the first normal section, the water metering device 200 can determine that the state of the tap water inside the distribution pipe is in a normal state.

Alternatively, in a state where the 2-1 point 330 is smaller than or equal to the 1-1 point 310 (FIG. 4b), the The water quality data may be greater than or equal to the 1-1 point 310 and less than or equal to the 2-2 point 340. By setting the corresponding section as the second normal section, the water metering device 200 can determine that the state of the tap water inside the distribution pipe is in a normal state.

For example, the range in which the electrical conductivity of the first measurement sensor 270 can be measured is 30 ㎲/cm to 52 ㎲/cm, and the range in which the electrical conductivity of the second measurement sensor 280 can be measured is 48 ㎲/cm to 70. In the case of ㎲/cm or less, the normal electrical conductivity range of the tap water inside the distribution pipe 210 is 48 ㎲/cm or more and 52 ㎲/cm or less.

On the other hand, as can be seen in FIG. 4A, there is a section that is greater than or equal to the 1-1 point 310 and less than or equal to the 2-1 point 330, and a section that is greater than or equal to the 1-2 point 320. A section smaller than or equal to the 2-2 point 340 may be referred to as a first abnormal section.

In addition, as can be seen in FIG. 4(b), there is a section that is greater than or equal to the 2-1 point 330, a section that is less than or equal to the 1-1 point 310, and a section greater than or equal to the 2-2 point 340. A section that is equal to or smaller than the 1-2 point 320 may be referred to as a second abnormal section.

When at least one of the water quality data acquired through the first measurement sensor 270 and the second measurement sensor 280 is included in the first abnormal section or the second abnormal section, the water metering device 200 operates in the distribution pipe. It can be determined that the condition of the tap water inside is abnormal.

For example, the range in which the electrical conductivity of the first measurement sensor 270 can be measured is 30 ㎲/cm to 52 ㎲/cm, and the range in which the electrical conductivity of the second measurement sensor 280 can be measured is 48 ㎲/cm to 70. If it is less than ㎲/cm, the abnormal electrical conductivity section of the tap water inside the distribution pipe 210 is more than 30 ㎲/cm but less than 48 ㎲/cm or more than 52 ㎲/cm and less than 70 ㎲/cm.

In addition, even if it falls outside the measurement range of the first measurement sensor 270 and the second measurement sensor 280 (the first and second normal sections, the first and second abnormal sections), the water metering device (200) may determine that the state of the tap water inside the distribution pipe is abnormal. In the above example, it would fall within the range of less than 30 μs/cm or more than 70 μs/cm.

In this way, by dividing the section and redundantly measuring the quality of tap water inside the distribution pipe 210 through a plurality of measurement sensors including the first measurement sensor 270 and the second measurement sensor 280, the distribution pipe 210 ) It is possible to reduce the influence of factors that interfere with water quality measurement, such as foam generation due to internal water pressure differences, and to obtain more accurate water quality data.

In addition, by using a plurality of measurement sensors, water quality data of tap water inside the distribution pipe 210 can be collected even if some of the measurement sensors malfunction, allowing more flexible response to malfunctions.

Meanwhile, the analysis server 100 is connected to a plurality of water metering devices for each individual, company, or institution that provides tap water, and when an abnormal state is confirmed in the water quality data obtained from one of the plurality of water metering devices , it is possible to track the point where abnormal water quality occurs (any water metering device).

For reference, in the normal section, in addition to the overlapping measurement range of the first measurement sensor 270 and the second measurement sensor 280, the user can arbitrarily set the normal section and abnormal section range.

Meanwhile, the water metering device 200 measures the inside of the distribution pipe 210 based on water quality data for the tap water inside the distribution pipe 210 obtained through the first measurement sensor 270 and the second measurement sensor 280. The condition of tap water can be analyzed.

At this time, the water metering device 200 determines whether the tap water inside the distribution pipe 210 is abnormal based on the water quality data for the tap water inside the distribution pipe 210 obtained through the first measurement sensor 270. If it is determined that the tap water inside the distribution pipe 210 is in a normal state based on the water quality data for the tap water inside the distribution pipe 210 obtained through the second measurement sensor 280, It can be determined that an error occurred in water quality measurement.

In addition, based on the water quality data for the tap water inside the distribution pipe 210 obtained through the first measurement sensor 270, it is determined that the tap water inside the distribution pipe 210 is in a normal state, and the second measurement If it is determined that the tap water inside the distribution pipe 210 is in an abnormal state based on the water quality data for the tap water inside the distribution pipe 210 obtained through the sensor 280, it is determined that an error occurred in water quality measurement. can do.

Afterwards, in a state where it is determined that an error has occurred in the water quality measurement, the tap water inside the distribution pipe 210 can be remeasured through the first measurement sensor 270 and the second measurement sensor 280. .

In addition, if it is determined that an error has occurred in water quality measurement continuously a certain number of times (ex. 5 times) or more, the water metering device 200 sends information that an error has occurred to the user terminal 300 through the analysis server 100. You can inform.

Additionally, if water quality data is not obtained from at least one measurement sensor through the first measurement sensor 270 and the second measurement sensor 280, it may be determined that an error has occurred in water quality measurement.

Additionally, the above process may be performed using the AI module included in the processor 120 of the analysis server 100.

In addition, the water metering device 200 of the present invention may include a plurality of meters 240, as can be seen in FIG. 3. The tap water flowing out from the distribution pipe 210 may be delivered to each of a plurality of households through the water supply pipe 230.

At this time, each of the plurality of meters 240 can check meter reading data (ex. tap water quantity, etc.) flowing into each of the plurality of households.

Therefore, the database 130 of the analysis server 100 linked to the water metering device 200 contains the tap water measured for each of a plurality of households (ex. household a, household b, etc.) using a plurality of meters 240. Average daily usage can be saved.

Additionally, the database 130 may also store household information (e.g., age of household members, number of household members) for each of the plurality of households. For example, information may be stored that household a includes one man in his 70s, and household b includes four people: a man in his 50s, a woman in her 50s, a man in his 20s, and a woman in her teens.

With the average daily usage of tap water stored in the database 130, the average daily usage (of tap water) during a specific period (ex. 1 week) of the first specific household is equal to the average daily usage of tap water (ex. It can be assumed that it is outside a certain range from 300L).

At this time, the processor 120 of the analysis server 100 may deliver a warning message to the terminal 300 corresponding to the first specific household that water usage is too much or too little than usual. The above process can be performed using the AI module included in the processor 120 of the analysis server 100 of the present invention.

Here, the terminal 300 corresponding to the first specific household may correspond to a terminal previously stored in the database 130. For example, if the first specific household consists of one senior citizen (a) in his 70s living alone, the terminal is the terminal of the senior citizen (a) living alone or the terminal of the child (a') of the senior citizen living alone (or the terminal of a related department such as a senior citizen protection group living alone) terminal). First, if the water usage of a specific household (a) is excessively lower than usual, the child (a’) will be able to immediately check what has happened to the health of the elderly person (a) living alone and take action.

On the other hand, when four or more members of a household are recorded in the database 130 and the average daily usage of the household is outside a certain range, the processor 120 of the analysis server 100 separates the household from the household. Warning messages may not be delivered unless requested to do so. In other words, whether or not the warning message is delivered can be determined by the number of household members.

In addition, when the number of household members is large, the certain range (based on average daily usage) that serves as a standard for delivering the warning message may be larger than when the number of household members is small. This is because when the number of members is large, the range of tap water usage (low or high) can be larger.

In addition, the processor 120 of the analysis server 100 charges the tap water usage cost of a second specific household with the lowest daily average usage among the plurality of daily average usage for a plurality of households, or causes the tap water usage cost to be billed at a discounted amount. You can apply. In other words, the analysis server 100 can directly charge the tap water usage fee, but it can also support billing of the tap water usage fee from another system (ex. water supply and sewage office, etc.).

At this time, the discount rate of the discounted amount may be determined based on the average value (A) of the average daily usage of each of the plurality of households and the average daily usage (B) of the second specific household. Specifically, the discount rate = A-B/A.

For example, if the average value (A) of the average daily usage of each of a plurality of households is 300L, and the average daily usage (B) of a second specific household is 200L, the discount rate is 300-200/300 = 33.333%, approx. It could be 33%.

In some cases, the processor 120 of the analysis server 100 provides a mini game to the household member terminal 300 of the second specific household, and the result of the mini game (33% discount, 50% discount, no discount) ), the discount rate can be determined. This is to reduce indiscriminate use of tap water and allow the use of the server (app) of the present invention.

Additionally, in another embodiment of the present invention, a plurality of households can be divided into two or more groups, and the household with the lowest average daily usage can be selected for each group. In addition, the processor 120 of the analysis server 100 provides a mini game to each household member terminal 300 of the selected household, and according to the result of the mini game (33% discount, 50% discount, no discount) You can also decide to have different discount rates.

In the above, the present invention has been described with specific details such as specific components and limited embodiments and drawings, but this is only provided to facilitate a more general understanding of the present invention, and the present invention is not limited to the above embodiments. , a person skilled in the art to which the present invention pertains can make various modifications and variations from this description.

Therefore, the spirit of the present invention should not be limited to the above-described embodiments, and the scope of the patent claims described below as well as all modifications equivalent to or equivalent to the scope of the claims fall within the scope of the spirit of the present invention. They will say they do it.
