At this time, the corresponding measurement information received through the control information receiving unit 10 to be described later is stored. Control information (control status information) of the same time zone of the facility is stored together and converted into data.

The lower equipment control unit 40 is configured to transmit the control signal of the lower equipment 1A to the on-site control panel 1 or the central control center 2 .

As shown in FIG. 3 , the lower facility control unit 40 includes a fixed control unit 41 that allows the lower level facility 1A to be operated in a fixed manner according to a real-time control value input by a user, and input through the fixed control unit 41 .

It includes an automatic control unit 43 for intelligent control.

Here, the fixed control unit 41 includes current control information received by the user through the control information receiving unit 10 , and real-time image information received through the image information receiving unit 20 and various types of measurement information received through the measurement information receiving unit 30 . Each of the control values of the lower equipment 1A is input based on the measurement information. In this case, when the user inputs a control value having a large difference in a predetermined range compared to the existing control information, the control value is used as a control signal in the field control panel ( 1) or it may be configured so that the user reconfirms the corresponding control value prior to delivery to the central control center (2).

At this time, when the control value is a flow control value, the flow control value is automatically increased or decreased according to the range of the upper and lower limit control values based on the increase or decrease of the flow or water level measurement information received from the measurement information receiving unit 30. can be

On the other hand, the automatic control unit 43 is a control value input by the user through the fixed control unit 41, control information received from the on-site control panel 1 and the central control sensor 2, and proportional control through the proportional control unit 42 It is configured to automatically extract an optimal control value using machine learning based on the stored data and deliver the extracted control value to the on-site control panel 1 or the central control center 2 .

That is, the automatic control unit 43 automatically extracts the current optimum control value based on the past control values and control information, the past measurement information and real-time measurement information, and in the following, the automatic control unit 43 will be described in more detail. It will be described in detail.

When the user selects automatic control through the automatic control unit 43, first, it is determined whether there is past measurement information (M _{PT ) that matches the real-time measurement information (M RT ) received from the measurement information receiving unit ( 30 ).}

To this end, the real-time measurement information (M _RT ) and the matching past measurement information (M _PT ) is searched in the data storage unit 50, and when the matching past measurement information (M _PT ) is searched, the searched past measurement information ( M _PT ) and the stored past control value (P _CV ) is extracted.

Then, based on the extracted past control value (P _CV ), the control signal is automatically transmitted to the on-site control panel (1) or the central control center (2) to control the subordinate equipment (1A).

On the other hand, real-time measurement information _(RT M) in the case of no historical measurement information (M _PT) to match, the real-time measurement information _(RT M) of the past measurement information, based on the approximate lower limit (HM _PT, LM _PT ) is retrieved from the data storage unit 50, respectively, and the first difference value (DV _{1 ) between the real-time measurement information (M RT} ) and the past measurement information (HM _PT ) of the upper limit approximation value, and the real-time measurement information ( M _RT ) and a second difference value (DV ₂ ) between the past measurement information (LM _PT ) of the lower limit approximation value is extracted, respectively, and the extracted first and second difference values (DV ₁ , The past control value (P _CV ) is extracted _{based on the past measurement information (HM PT} ) of the upper limit approximation value or the past measurement information (LM _PT ) of the lower limit approximation value having a smaller value among _{DV 2 ).}

Here, the first and second difference values (DV ₁ , DV _{2 ) of past measurement information (HM PT} , approximation of the upper and lower limits having the smaller value) If the past control value (P _{CV ) is extracted based on LM PT} ) and applied as the current control value as it is, a large error that does not match between the actual field situation and the control value of the sub-equipment 1A may occur, and this In this case, the operation efficiency may be relatively lower compared to the manual control of the equipment by the user.

In addition, simply the first and second difference values (DV ₁ , DV _{2 ), past measurement information (HM PT} , approximation of the upper and lower limits of the smaller value) If the past control value (P _{CV ) is extracted based on LM PT} ) and applied as the current control value, there is still no matching past measurement information (M _PT ) for the same real-time measurement information (M _{RT ).} As a result, even if a large amount of control values are stored in the data storage unit 50 for long-term operation, _{a situation that does not match the real-time measurement information (M RT} ) occurs continuously, which reduces the reliability of intelligent automatic control. Trees can be a problem.

In order to solve this problem, control values suitable for various situations are input in advance to the data storage unit 50 through the manual control unit 41 or the difference between approximate values is automatically narrowed by accumulating data between uses, resulting in long-term operation When a wide range of data is accumulated, errors are naturally reduced and the reliability of intelligent automatic control can be guaranteed.

Of these, there is a physical limit to directly inputting a control value suitable for various situations, and therefore, the present invention provides a method of _{matching the real-time measurement information (M RT} ) and the past measurement information (M _PT ) to match the searched upper and lower limit approximation values when there is no previous measurement information (M PT ). Past measurement information (HM _PT , The first and second difference values (DV ₁ , of LM _{PT )} DV ₂ ) by applying the correction value (C _V ) to the past control value (P _{CV ) matching the past measurement information (HM PT} ) of the upper limit approximation value (HM PT ) or the past measurement information (LM _{PT ) of the lower limit approximation value having the smaller value among DV 2 )} It may be configured to transmit a control signal toward the control panel 1 or the central control center 2 .

At this time, the correction value (C _V ) may be a value arbitrarily set by the user, or alternatively, the first past control value (HP _{CV ) stored in the past measurement information (HM PT} ) of the upper limit approximate value and the past measurement information of the lower limit approximate value After the difference value DV ₃ of the second past control value LP _CV stored in (LM _PT ) is obtained, the difference value DV ₃ may be obtained by ½.

Through the above configuration, real-time measurement information (M_RT) and the historical measurement information (M_PT), the past measurement information (HM) of the upper and lower limit approximations_PT, LM_PT) of the first and second difference values (DV_One, DV₂) of the past measurement information (HM) of the upper limit approximation having the smaller value_PT) or past measurement information of the lower limit approximation (LM_PT) matching the past control value (P_CV) to the correction value (C_V) is applied to the control value is stored in the data storage unit 50, and then real-time measurement information (M_RT) is received, the past measurement information (HM)_PT, LM_PT) is reduced, and as a result, as the data is accumulated, the error of the control value is reduced, and the reliability of the intelligent automatic control of the lower equipment 1A is improved.

The data storage unit 50 is configured to store, as operation data, a control value matched to the corresponding measurement information along with the time and date measurement information of the lower equipment 1A controlled through the lower equipment control unit 40 .

The data storage unit 50 may be configured to automatically store data by periodically backing up data to the main server, and the control value input in real time through the fixed control unit 41 and the measurement information obtained in real time at the same time period are matched together. may be configured to be stored.

In addition, when the lower equipment 1A is controlled by manually inputting a control value, the name or administrator number of the user who entered the control value may be stored together, and in this case, the user's name or administrator number is The name or manager number input when the integrated monitoring control device 3 is connected may be configured to be automatically matched and stored.

On the other hand, the integrated monitoring and control device 3 may further include a failure diagnosis unit 60 for monitoring the change trend of the measurement information value received through the measurement information receiving unit 30 to determine whether the lower equipment 1A has a failure. can

The failure diagnosis unit 60 may be configured to guide the failure of the corresponding measurement equipment when the change trend of the measurement information value received through the measurement information receiving unit 30 is out of a set error range.

At this time, it may be configured to additionally determine whether the change in the measurement information value is due to an abnormality or failure of the corresponding sub-equipment 1A, or an abnormality or failure of the measurement device. If there is an abrupt change in the change trend of the value out of the set error range, it is configured to compare the change trend of other measurement information except the corresponding measurement information.

And if the change trend of other measurement information has a similar or the same change trend as the corresponding measurement information having a sudden change, it is determined that the subordinate equipment 1A of the corresponding measurement information is abnormal operation or failure, and the change trend of other measurement information is Unlike the corresponding measurement information having a sudden change, if there is no change or the change trend is not large, it is determined as a failure of the corresponding measurement device.

Through the above configuration, it is possible to accurately determine whether a failure is caused by an abnormal operation of the measuring device or the subordinate equipment 1A, and as a result, it is possible to quickly respond to the failure.

On the other hand, in the measurement information receiving unit 30, a water quality sensor (not shown) is installed on the pipe with a pair of valves spaced apart by a predetermined interval therebetween, and through this, the turbidity of the water flowing inside the pipe is detected to measure the quality of the water. can be configured to measure.

At this time, if the flow rate of water in the pipe is fast, it may be difficult to accurately detect the turbidity of the water. Therefore, when measuring the water quality through the water quality sensor, the opening degree of both pipes is automatically adjusted to It may be configured to measure the water quality in a state where the flow of water is stopped by reducing the flow rate below a set flow rate or by closing both valves.

If the flow rate inside the pipe is frequently reduced or the flow of water is stopped to measure the water quality in this way, the smooth operation of the water supply facility may be hindered. Therefore, water quality measurement through the above method is performed 1-2 times a day, 1 week. It can be set in the measurement information receiving unit 30 to be measured ~ 3 times or by the user's selection.

Here, if the water quality measurement is set to be measured 1 to 2 times a day, 1 to 3 times a week, it can be set to be measured during a time period in which the use of constant is relatively small, and when water quality is measured with both valves closed It may be configured to measure the water quality through the water quality sensor after 3 to 5 minutes have elapsed with the valve fully closed so that the water quality can be measured after this complete stagnation.

In addition, only when the water quality measured by the water quality sensor is below the standard value, water may be secondarily purified through a separate secondary water purifying device and then supplied to the user. In comparison, the operation efficiency and service life (filter, etc.) of the secondary water purification device are relatively improved.

As described above, in the present invention, the user selects among the manual, proportional, and automatic operation modes of the integrated monitoring and control device, and the control information of the lower equipment is transmitted to the on-site control panel or the central control center. Since it is proportionally controlled appropriately according to the lower limit setting value, the lower equipment can be quickly and automatically controlled in response to changes within a predetermined range that occur during operation. Alternatively, after the approximate value data is extracted, when the approximate value data is extracted, the correction value is applied to control the lower equipment. As a result, the lower equipment is more accurately and stably controlled through the integrated monitoring and control device according to various on-site conditions. will become
