It may be a device for controlling the state.

(10) can be controlled.

Hereinafter, the water treatment facility monitoring and control apparatus 100 will be described in detail with reference to FIG. 2 .

2 is a diagram schematically illustrating an apparatus 100 for monitoring and controlling a water treatment facility according to an embodiment of the present invention.

Referring to FIG. 2 , the water treatment facility monitoring and control device 100 includes an information collection unit 110 , a defect determination unit 120 , a communication unit 130 , a control command suitability determination unit 140 , and a control command execution unit 150 . ) may be included.

The information collection unit 110 may be configured to collect facility information on the water treatment facility 10 .

Specifically, the information collection unit 110 may be communicatively connected to the measurement device 11 of the water treatment facility 10 . In addition, the information collection unit 110 may receive facility information on the water treatment facility 10 from the measurement device 11 .

For example, the information collection unit 110 may receive facility information from the measurement device 11 at predetermined intervals.

The defect determination unit 120 may be configured to determine whether a defect occurs in the water treatment facility 10 from facility information using a preset learning model.

Specifically, the learning model may be pre-trained to output the current state of the water treatment facility 10 corresponding to the facility information when the facility information is input. For example, the learning model receives the temperature, water level, water pressure, flow rate, flow rate, operation state of the pump and valve, etc. of the water measured by the measuring device 11, and determines the current state of the water treatment facility 10 as a normal state or a defective state. It can be learned in advance to determine Therefore, the defect determination unit 120 inputs the facility information collected by the information collection unit 110 to the learning model, and determines whether a defect occurs in the water treatment facility 10 according to the result output from the learning model. there is.

More specifically, the factors included in the facility information are compared with a reference value (or reference range) that has been learned and set in advance for each, and based on the comparison result, it can be determined whether a defect occurs in the water treatment facility 10 . For example, when the water level of the water treatment facility 10 differs from the reference value by more than a threshold or the water level is out of the reference range, it may be determined that a defect has occurred in the water treatment facility 10 .

In addition, two or more factors among a plurality of factors included in the facility information may be selected, and the state of the water treatment facility 10 may be determined based on the correlation between the selected factors. Specifically, the learning model may select some or all of the factors included in the facility information, and determine some of the selected factors as the reference factors. And, the learning model may determine the state of the water treatment facility 10 by checking whether the values of the remaining factors among the selected factors can be derived from the reference factors based on the correlation learned in advance with respect to the selected factors.

Preferably, the learning model may be selected by combining two or more factors included in the facility information, and may determine the state of the water treatment facility 10 based on each combination. For example, assuming that a total of n factors included in the facility information, the number of combinations of factors that can be selected by the learning model may be “2 ⁿ -n-1”. This may be calculated according to the formula "2 ⁿ - _n C ₀ - _n C ₁ " when considering the number of cases in which two or more factors are selected from among the n factors. In addition, one or more reference factors and the remaining factors may be determined in each factor combination. And, the learning model may determine the state of the water treatment facility 10 based on the correlation preset to correspond to, the reference factor, and the remaining factors for each factor combination. Assuming that the number of factors included in one factor combination is m, the number of sub-combinations of the reference factor and the remaining factors that can be selected by the learning model may be “2 ^m −2”. This is the number of cases in which 1 to m-1 reference factors are selected among the m factors, and can be calculated according to the formula of "2 ^m - _m C ₀ - _m C _m ".

In conclusion, the learning model can determine whether the water treatment facility 10 is defective by comparing as much as the value derived from the following equation.

[Equation]

Here, N is the maximum number of comparisons of the learning model for determining whether the water treatment facility 10 is defective, n is the number of factors included in the facility information, and m is a combination of 2 to n factors for selection variable, and i is a variable for which 1 to m-1 factors are selected as reference factors. nCm denotes the number of cases in which m factors are selected from among n factors, and mCi denotes the number of cases in which i factors among m factors are selected as reference factors.

For example, the learning model may determine the water level and water pressure among the water level, water pressure, and flow rate of the input waterseo facility 10 as reference factors, and determine the flow rate as the remaining factors. The learning model may determine a predicted value (or predicted range) for the flow rate from the input water level value and water pressure value based on the pre-learned correlation with the water level, water pressure, and flow rate. And, the learning model may determine the state of the water treatment facility 10 by comparing the predicted value (or predicted range) with the value of the input flow rate. If, there is a difference between the predicted value and the value of the input flow rate by more than a threshold value, or if the value of the input flow rate does not fall within the predicted range, it may be determined that a defect has occurred in the water treatment facility 10 . And, the learning model may check whether the value of the input water pressure is derived, based on the value of the input water level, the value of the input flow rate, and the correlation, the value of the input water pressure, the value of the input flow rate, and the correlation Based on the , it may be checked whether the input water level is derived.

The communication unit 130 may be configured to transmit defect information about the defect to the manager device 20 when it is determined that a defect has occurred in the water treatment facility 10 by the defect determination unit 120 .

Specifically, the communication unit 130 may transmit defect information indicating that a defect has occurred in the water treatment facility 10 to the manager device 20 using wired and/or wireless communication.

The communication unit 130 may be configured to receive a control command including control information corresponding to the defect information from the manager device 20 .

Specifically, the control information may be information for controlling an operation state of a pump and a valve. For example, the control information may include information on operation of a pump and/or opening/closing of a valve. As a more specific example, the control information may include information related to the operation of the pump, such as the operation state (on or off) and/or the speed of the pump, and information on the opening and closing of various valves provided in the water treatment facility.

The control command suitability determining unit 140 may be configured to determine whether the control information included in the control command received by the communication unit 130 is included in a preset guide line.

For example, the guideline is a settable value, a settable range (eg, a range of settable values) or a settable state (eg, on or off) may be. That is, the guide line may be preset for each of the control devices 12 of the water treatment facility 10 . These guide lines may be preset in consideration of the specifications of each of the control devices 12 .

The control command suitability determining unit 140 may determine the suitability of the corresponding control command by determining whether the control information included in the control command received from the manager device 20 corresponds to (in particular, included) the guide line. .

For example, when the control information included in the control command is included in the guide line, the control command suitability determining unit 140 may determine that the corresponding control command is appropriate.

Conversely, the control information included in the control command is not included in the guideline. In this case, the control command suitability determining unit 140 may determine that the corresponding control command is inappropriate.

The control command execution unit 150 may be configured to determine whether to execute the control command according to the suitability determination result of the control command suitability determination unit 140 .

Specifically, when it is determined that the control command is appropriate by the control command suitability determining unit 140 , the control command execution unit 150 may control the water treatment facility 10 according to control information included in the control command. . More specifically, the control command performing unit 150 may control the water treatment facility 10 by controlling each of the control devices 12 according to the control information.

For example, the control command performing unit 150 may control the opening and closing of a pump and/or a valve provided in the water treatment facility by controlling the control device according to the control command.

The water treatment facility monitoring and control device 100 according to an embodiment of the present invention can not only remotely monitor the water treatment facility 10 , but also remotely control each of the control devices 12 of the water treatment facility 10 . there are advantages to In addition, the water treatment facility monitoring and control device 100 has the advantage of being able to selectively perform only the control command corresponding to the water treatment facility 10 by determining the suitability of the control command received from the manager device 20 .

Meanwhile, the water treatment facility monitoring and control device 100 may further include a storage unit 160 . The storage unit 160 may store data necessary for each component of the water treatment facility monitoring and control apparatus 100 to perform an operation and function, or data generated in the process of performing a program or operation and function. The storage unit 160 is not particularly limited in its type as long as it is a known information storage means capable of writing, erasing, updating, and reading data. As an example, the information storage means may include RAM, flash memory, ROM, EEPROM, registers, and the like. In addition, the storage unit 160 may store program codes in which processes executable by each component of the water treatment facility monitoring and control apparatus 100 are defined.

Hereinafter, the water treatment facility monitoring and control apparatus 100 will be described in more detail with reference to FIGS. 3 to 6 .

3 to 6 are diagrams schematically illustrating the operation configuration of the apparatus 100 for monitoring and controlling a water treatment facility according to an embodiment of the present invention.

In step S110 , the information collection unit 110 may collect facility information on the water treatment facility 10 . Specifically, the information collection unit 110 may be connected to the measurement device 11 of the water treatment facility 10 to collect facility information from the measurement device 11 .

In step S120 , the defect determination unit 120 may determine whether a defect occurs in the water treatment facility 10 according to the facility information collected by the information collection unit 110 . Specifically, the defect determination unit 120 may determine the state of the water treatment facility 10 corresponding to the collected facility information using a preset learning model. For example, the defect determination unit 120 may determine the state of the water treatment facility 10 as a normal state or a defective state.

Step S130 may be performed when the defect determination unit 120 determines that a defect has occurred in the water treatment facility 10 in step S120 . In step S130 , the communication unit 130 may transmit the defect information to the connected manager device 20 through wired and/or wireless communication.

In step S140 , the communication unit 130 may receive a control command including control information corresponding to the defect information from the manager device 20 . Here, the control command may be a command including control information on at least one control device 12 provided in the water treatment facility 10 .

In operation S150, the control command suitability determining unit 140 may determine whether the control information included in the control command is included in a preset guide line. If the control information is included in the guideline, step S160 may be performed, and if not included, step S210 may be performed.

When it is determined by the control command suitability determination unit 140 that the control command is appropriate (the result of step S150 is YES), in step S160, the control command execution unit 150 performs the control command to ) can be controlled. Specifically, the control command performing unit 150 controls the operation state of at least one control device 12 provided in the water treatment facility 10 to correspond to the control information included in the control command, thereby controlling the water treatment facility 10 . can be controlled

When it is determined by the control command suitability determination unit 140 that the control command is not appropriate (the result of step S150 is NO), in step S210, the control command execution unit 150 requests the control command to be modified. You can create correction request information. Here, the correction request information may include a notification that a preset guideline and corresponding control information are not included in the guideline.

For example, it is assumed that a plurality of pieces of control information is included in the control command, and some of the plurality of pieces of control information are not included in a corresponding guide line. The control command execution unit 150 may generate correction request information for some control information not included in the corresponding guideline.

In step S220 , the control command performing unit 150 may determine whether the modification request information has been generated for a preset threshold number of times. If the correction request information is generated a preset threshold number of times, step S410 may be performed, otherwise, step S230 may be performed.

To this end, the control command execution unit 150 may count the number of times of generation of the modification request information whenever the modification request information is generated. Here, the control command performing unit 150 may count the number of times of generation of the correction request information for one control command by one.

For example, as in the previous embodiment, when some control information among a plurality of control information included in one control command is not included in a corresponding guide line, the control command performing unit 150 requests a correction corresponding to the partial control information. Information may be generated, and the number of times of generation of the correction request information may be increased by one. That is, even if the modification request information corresponding to a plurality of pieces of control information is generated for one control command, the number of generation of the modification request information may be increased by one.

In step S230 , the control command execution unit 150 may transmit the modification request information to the manager device 20 through the communication unit 130 . That is, when the number of generation of the modification request information is less than the threshold number (the result of step S220 is NO), the communication unit 130 may transmit the generated modification request information to the manager device 20 .

When the communication unit 130 receives a correction command from the manager device 20 (when the result of step S240 is YES), step S250 is performed, otherwise (when the result of step S240 is NO), step S310 is performed can be

In operation S250, the control command suitability determining unit 140 may determine whether the corrected control information included in the correction command is included in a preset guideline. If the control information is included in the guideline, step S160 may be performed, and if not included, step S310 may be performed.

That is, in step S250 , the control command suitability determining unit 140 may determine whether the control information included in the correction command is included in the guide line. And, when it is determined by the control command suitability determination unit 140 that the correction command is appropriate (the result of step S250 is YES), the control command execution unit 150 in step S160 performs a correction command to 10) can be controlled.

Step S310 may be performed when the communication unit 130 does not receive the correction command in step S240 or when it is determined that the correction command is not suitable by the control command suitability determining unit 140 in step S250. That is, when the result of step S240 is NO or when the result of step S250 is NO, step S310 may be performed.

In step S310, the control command execution unit 150 requests the control simulation of the water treatment facility 10 based on the control command or the correction command to the defect determination unit 120, and the result of the control simulation from the defect determination unit 120 can receive

For example, when the communication unit 130 does not receive a correction command from the manager device 20 , the control command execution unit 150 may request a simulation based on the control information from the defect determination unit 120 .

As another example, when the communication unit 130 receives a correction command from the manager device 20 , but the corrected control information included in the correction command is not included in the guide line, the control command execution unit 150 is a defect determination unit It is possible to request a simulation based on the modified control information in (120).

Here, the defect determination unit 120 may perform a simulation on the control information using a pre-trained learning model. For example, the defect determination unit 120 inputs the facility information on the water treatment facility 10 and the control information received from the control command execution unit 150 to the learning model, thereby normalizing the predicted state for the water treatment facility 10 . It can be determined by state or fault state.

If the simulation result in step S320 is a result of a defect, step S330 may be performed; otherwise, step S160 may be performed.

For example, when the result of the control simulation is the first simulation result that the defect does not occur in the water treatment facility 10 (when the result of step S320 is NO), the control command execution unit 150 performs a control command or a correction command to control the water treatment facility (10).

That is, if the control information is not included in the guideline, but it is expected that a defect will not occur in the water treatment facility 10 as a result of the simulation, the control command execution unit 150 is configured to promptly handle the defect in the water treatment facility 10 . , it is possible to control the water treatment facility 10 according to the control command. However, since the water treatment facility 10 is controlled based on control information not included in the guideline, the control command execution unit 150 may record information such as the corresponding control information and simulation results.

In step S330 , the control command execution unit 150 may transmit the simulation result to the manager device 20 through the communication unit 130 .

For example, when the result of the control simulation is the second simulation result that a defect is generated in the water treatment facility 10 (when the result of step S320 is NO), the control command execution unit 150 is the manager device through the communication unit 130 . A second simulation result may be transmitted to (20). In addition, the control command execution unit 150 may control the water treatment facility 10 based on a response to the second simulation result from the manager device 20 .

In step S340 , the control command execution unit 150 may determine whether a forced execution command has been received from the manager device 20 through the communication unit 130 . If the control command execution unit 150 receives the forced execution command from the manager device 20 , step S160 may be performed, otherwise step S210 may be performed.

When the control command execution unit 150 receives a command to forcibly execute a control command or a correction command as a response from the manager device 20 through the communication unit 130 (when the result of step S340 is YES), according to step S160 The control command execution unit 150 may control the water treatment facility 10 according to a control command or a correction command.

For example, when a defect occurs in the water treatment facility 10 , the manager may want to quickly control the control device 12 to take emergency measures for the water treatment facility 10 . Accordingly, when the control command execution unit 150 receives a command to forcefully perform the most recently received command (control command or correction command) from the manager device 20 , the control device 12 controls the control device 12 to correspond to the command. By controlling, the water treatment facility 10 can be controlled. In this case, although the simulation result by the defect determination unit 120 is a second simulation result indicating that a defect occurs, the control command execution unit 150 for emergency control of the water treatment facility 10 controls the most recently received control. It is possible to control the water treatment facility 10 according to the information. However, since the water treatment facility 10 is controlled based on control information not included in the guideline, the control command execution unit 150 may record information such as the corresponding control information and simulation results.

If the control command execution unit 150 does not receive a command to forcibly perform a control command or a correction command as a response from the manager device 20 through the communication unit 130 (the result of step S340 is NO), step S210 is can be performed.

For example, in step S210 , the control command performing unit 150 may regenerate modification request information for requesting modification of the control command or the modification command. And, in step S220 , the control command execution unit 150 may transmit the modification request information to the manager device 20 through the communication unit 130 . Thereafter, the steps below step S230 may be performed by the water treatment facility monitoring and control device 100 .

In step S410, the control command performing unit 150 may be configured to control the water treatment facility 10 based on a preset guideline.

That is, when the number of generation of the correction request information is the critical number (the result of step S220 is YES), the control command performing unit 150 determines guide information for controlling the water treatment facility 10 based on the guideline. can

As described above, the guideline is a settable value, a settable range (eg, a range of settable values) or a settable state (eg, a range of settable values) for each of the control devices 12 in which the water treatment facility 10 maintains a normal state. , on or off). The control command execution unit 150 may determine guide information with reference to a preset guide line for the control device 12 corresponding to the correction request information.

For example, when the guide line corresponding to the control device 12 is a settable value, the control command performing unit 150 may determine the settable value as guide information, and control the corresponding control device 12 according to the guide information. there is.
