Description

IOT chlorine feeder management system reflecting water quality analysis data

The present invention relates to an IOT chlorinator management system that reflects water quality analysis data.

Most areas have well-equipped water supply facilities, so there is no need to worry about procuring drinking water. However, in some areas, such as remote mountainous areas, there are no water facilities, so natural water such as groundwater is used as drinking water. Such natural water may contain harmful bacteria. Therefore, natural water is disinfected and sterilized before it is used as drinking water. Chlorine is used to disinfect natural water. The chlorine agent, that is, sodium hypochlorite (Sodium Hypochlorite) is effective for sterilization of most organisms, so the disinfection of natural water can be made stably by using the chlorine agent. However, if the chlorine agent is excessively added during the disinfection process of natural water, the smell of the drug is felt relatively strongly during the drinking process, which may lead to resistance to drinking.

Conventionally, chlorine injectors of small-scale water supply facilities, such as village water supply in mountainous areas, etc., are installed in mountainous highlands and underground water wells that are inconvenient to access. Therefore, it is not easy to manage the chlorine injector, so there is a problem in that the chlorine disinfection function cannot be assured in using natural water as domestic water.

For example, the chlorine input device 20 is a storage tank in which the chlorine agent is stored, a pump for pumping the chlorine agent stored in the storage tank, a discharge pipe for discharging the chlorine agent pumped by the pump and supplying the chlorine agent to the water tank 10, the operation of the pump It may include a controller to control, and the like.

The flow meter 30 is installed in a natural water supply pipe through which the natural water supplied to the water tank 10 passes, and measures the flow rate of the natural water supplied to the water tank 10 . Through this, the amount of natural water newly generated and supplied to the water tank 10 may be calculated in real time.

The thermometer 40 measures the temperature of the area where the IOT chlorine injector management system according to an embodiment of the present invention is installed. For example, the thermometer 40 may be installed around the water tank 40 , around the pipeline 5 , around the town hall 1 , and the like to measure the temperature.

The conduit length adjuster 50 is installed in the middle of the conduit 5 and serves to vary the length of the conduit 5 according to the control of the control server 70 to be described later.

For example, the conduit length adjuster 50 forms a preset additional length in the basic conduit 52, the basic length to form a preset basic length for the entire conduit 5, as shown in FIG. 2, A plurality of additional conduits 54 and 56 connected in parallel with the main conduit 52, the main conduit 52 and a plurality of valves 51 , 53 and 55 for opening and closing the plurality of additional conduits 54 and 56, respectively. can be configured. That is, as shown in FIG. 2 , the basic conduit 52 is formed in a straight line, and the additional conduits 54 and 56 are wound at least once to form an additional length preset with respect to the basic conduit 52 . can be formed. Referring to FIG. 2 , the additional length of the second additional conduit 56 may be formed to be twice the additional length of the first additional conduit 54 . Although not shown in FIG. 2 , with this pattern, the additional length of the third additional conduit is three times the additional length of the first additional conduit 54 , and the additional length of the fourth additional conduit is that of the first additional conduit 54 . It can be formed with 4 times the additional length, etc. In this way, the plurality of additional conduits 54 and 56 may have different lengths, and may be formed in a form in which the length increases step by step. And, under the control of the control server 70, only the valve of the conduit to be used among the plurality of valves 51, 53, 55 may be opened, and other valves may be closed.

The chlorine meter 60 is finally installed at the end of the pipe 5 of the place of use where the natural water is supplied, and measures the residual chlorine amount of the supplied natural water.

For example, the chlorine meter 60 is a pipe leading into the village hall 1 that serves as a management center for a small-scale water supply facility, as shown in FIG. 1, in order to measure the amount of residual chlorine in natural water to be used immediately. It may be installed to measure the residual chlorine amount of natural water present in the pipe (5) in the vicinity of the faucet (3) installed at the end of (5).

The chlorine input device 20, the flow meter 30, the thermometer 40, the pipe length regulator 50, the chlorine meter 60, etc. described above perform wireless communication with the control server 70 to be described later to control the measurement data. 70 , or an operation command may be received from the control server 70 . For example, when the chlorine injector 20, the flow meter 30, and the thermometer 40 are physically installed in a short distance, one wireless communication means may be used to communicate with the control server 70.

The control server 70 calculates the storage amount of natural water stored in the water tank 10 using the water level of the water tank 10 measured by the water level gauge installed in the water tank 10 , and the natural water stored in the water tank 10 . of the stored amount, the supply amount of the newly generated natural water supplied to the water tank 10 through the natural water supply pipe, and the residual chlorine amount measured by the chlorine meter 60 are monitored.

And, the control server 70 uses a preset ratio of water and chlorine agent to determine the storage amount of natural water stored in the water tank 10 and the amount of natural water newly created and supplied to the water tank 10 through the natural water supply pipe. The amount of chlorine agent is calculated according to the combined amount of water, and the chlorine injector 20 can control the calculated amount of the chlorine agent to be introduced into the water tank 10 .

And, when the residual chlorine amount measured by the chlorine meter 60 exceeds a preset threshold, the control server 70 chlorine It is possible to control the injector 20 to be put into the water tank 10 .

In addition, the control server 70 additionally monitors the temperature and the length of the pipeline 5 measured by the thermometer 40, and through learning, from the quantity of chlorine agent calculated according to the amount of storage and supply, the quantity of water , an appropriate amount of chlorine agent is calculated in consideration of the temperature and the length of the pipeline 5 , and the chlorine injector 20 can control the calculated amount of chlorine agent to be introduced into the water tank 10 .

For example, as the temperature of the chlorine agent added to the natural water increases, and the length of the pipe 5 increases, the evaporation rate may increase. Therefore, in an embodiment of the present invention, learning can be performed by applying this principle.

Referring to FIG. 3 , the control server 70 may include a communication unit 71 , a data collection unit 72 , a learning unit 73 , and a control unit 74 .

The communication unit 71 includes components of the IOT chlorine injector management system according to an embodiment of the present invention (eg, a water tank 10, a chlorine injector 20, a flow meter 30, a thermometer 40, and a pipe length adjuster). (50), chlorine meter (60, etc.) and performs wireless communication.

For example, the communication unit 71 receives the measurement data from the water tank 10 , the flow meter 30 , the thermometer 40 and the chlorine meter 60 , and the chlorine input unit 20 and the pipe length adjuster 50 . An action command can be sent.

The data collection unit 72 collects measurement data received from the water tank 10 , the flow meter 30 , the thermometer 40 , and the chlorine meter 60 through the communication unit 71 .

That is, the data collection unit 72 stores the amount of natural water stored in the water tank 10 calculated from the water level measured by the water level gauge of the water tank 10 , measured by the flow meter 30 and supplied to the water tank 10 . The amount of natural water supplied, the temperature measured by the thermometer 40, and the residual chlorine amount of the supplied natural water measured by the chlorine meter 60 may be collected.

In addition, the data collection unit 72 controls the pipe length adjuster 50 to vary the length of the pipe 5, and obtains the amount of residual chlorine measured by the chlorine measuring device 60 for each variable length, It is possible to collect data on the amount of residual chlorine by the amount of water that is the sum of the storage and supply and the length of the pipeline 5 .

The learning unit 73 repeatedly learns the collected residual chlorine amount data that changes according to the amount of water, the temperature, and the length of the pipeline 5, and the residual chlorine amount by water amount, temperature, and length of the pipeline 5 based on the learning Calculate the prediction data for

For example, the learning unit 73 learns by using regression analysis, classification, time-series pattern analysis, etc. It is possible to calculate the predicted data for the amount of residual chlorine for each length.

Here, the regression analysis is a method of estimating the closest straight line, curved surface, etc. to the collected residual chlorine amount data by water volume, temperature, and pipe length (5), and through this, predictive data for residual chlorine amount can be calculated. Such regression analysis has a relatively fast modeling speed, is easy to find the cause sensor when anomalies occur, and a sensor with low correlation acts as noise, so it needs to be removed.

And, for classification, prediction data for the amount of residual chlorine can be calculated based on the distribution of the amount of residual chlorine data for each collected water volume, temperature, and length of the pipeline 5 . This classification is applied to a sensor to which a regression method cannot be applied due to a low correlation index, and is generally applied as a pair by tying two sensors to remove noise, and occupies a large amount of memory.

And, the time series pattern analysis is a method of predicting future data based on past data patterns according to time, and through this, prediction data for the amount of residual chlorine by water volume, temperature, and length of the pipeline 5 can be calculated. Such time series pattern analysis is applied to each sensor, and it takes a relatively long time to learn, so it has a characteristic that it is applied only to major sensors.

The control unit 74 calculates the quantity of the chlorine agent according to the amount of water that is the sum of the amount of storage of natural water and the amount of supply of natural water by using a preset ratio of water and chlorine agent, and the chlorine input unit 20 uses the calculated amount of chlorine agent. It can be controlled to be put into the water tank (10).

And, when the measured residual chlorine amount exceeds a preset threshold value, the control unit 74 injects a reduced amount of chlorine agent according to a preset chlorine agent reduction ratio for each fraction exceeding the threshold value of the residual chlorine amount to the chlorine injector 20 into the water tank ( 10) can be controlled to input.

That is, the control unit 74 may calculate the appropriate amount of chlorine agent input by applying the chlorine agent reduction ratio according to the excess of the threshold value of the residual chlorine amount to the quantitative amount of the chlorine agent according to the amount of water.

On the other hand, the control unit 74 uses the prediction data for the amount of residual chlorine by the amount of water, the temperature, and the length of the pipe 5 calculated by the learning unit 73, the currently measured water quantity, the currently measured temperature and the current pipe ( It is possible to calculate the appropriate amount of chlorine agent input according to the length of 5). For example, the length value of the current conduit 5 may be input from the user.

That is, the control unit 74 calculates the calculated amount of water, the temperature, and the length of the pipeline 5 from the predicted data for the residual chlorine amount by the calculated amount of water, the temperature, and the length of the pipeline 5. The amount of residual chlorine may be derived, and the appropriate amount of chlorine agent input for the amount of chlorine agent according to the amount of water may be calculated according to the derived residual chlorine amount.

At this time, as described above, when the derived residual chlorine amount exceeds a preset threshold value, the control unit 74 applies a preset chlorine agent reduction ratio for each fraction exceeding the threshold value of the residual chlorine amount to the quantitative amount of the chlorine agent according to the amount of water. An appropriate amount of input can be calculated.

In addition, the control unit 74 may control the chlorine injector 20 to inject the calculated appropriate amount of the chlorine agent into the water tank 10 .

Also, as shown in FIG. 4 , the control unit 74 may output various measurement data through a screen in real time and provide it to the user.
