Description

Water pressure turbidity monitoring system for pipe passage {Water quality monitoring system for water supply line}

When performing work such as relocating a water supply pipe, laying a new pipe, or recovering from an accident, the pipe passing work must be accompanied. However, the pipe passage work must be carried out very sensitively, as there is a high possibility of occurrence of risk factors in the water supply, such as pressure change in the pipe and generation of turbid water.

In the conventional water passage work, the points at which water pressure and turbidity, which are the main factors of the pipeline water passage work, can be checked are very limited, and the operator directly brings a simple turbidity meter and collects a sample at the time of the operator's own judgment to measure the turbidity, There was a problem that it was difficult to acquire real-time data, and there was no choice but to rely on the empirical judgment of the creator.

In this case, the turbidity value was measured below the set value on the sample collected by the worker and the supply of water was resumed, but after the manager left the site, an accident such as a secondary source of pollution flowing in and providing contaminated water to the consumer may occur. There was room.

Therefore, there is a need to develop a system that allows water pressure and turbidity values to be acquired in real time at major points on the water supply pipe and analyzed data to enable fast and accurate water flow.

Meanwhile, a decompression chamber 112 to be described below may be provided on the rear surface of the housing, and the decompression chamber 112 may be fixedly coupled to the rear surface of the housing or may be installed in a detachable form.

The water quality inlet 113 serves to supply water for turbidity measurement to the turbidity measurement unit 110 from the outside, and for this purpose, it is provided to penetrate the inside and outside of the housing. The water quality inlet 113 provides water from the decompression chamber 112 to the turbidity measuring unit 110 in the form of a hose or a pipe.

The turbidity measuring unit 110 serves to measure the turbidity of the water supplied from the water quality inlet 113 to generate a turbidity measurement value, and for this purpose, it is provided in the housing and is coupled in communication with the water quality inlet 113 . .

The turbidity measurement unit 110 is electrically connected to the wireless transceiver so that the generated turbidity measurement value can be transmitted to the outside, and also with the display module 130 so that the turbidity measurement value can be expressed on the display module 130 . electrically connected.

The wireless transceiver serves to transmit the turbidity measurement value generated by the turbidity measurement unit 110 to the outside, and for this purpose, it is provided inside the housing and is electrically connected to the turbidity measurement unit 110 . In this case, the antenna of the wireless transceiver may be provided outside the housing.

On the other hand, the wireless transceiver is also electrically connected to the water pressure measurement unit 120, and at this time, similarly transmits the water pressure measurement value generated by the water pressure measurement unit 120 to the outside. The turbidity measurement value and the water pressure measurement value transmitted from the wireless transceiver to the outside are transmitted to the control unit 200 or transmitted to the manager terminal 300 .

The water pressure inlet (not shown) serves to supply water for water pressure measurement to the water pressure measurement unit 120 from the outside, and for this purpose, it is provided to penetrate the inside and outside of the housing. The hydraulic inlet provides water supplied through the hydraulic line to the hydraulic pressure measuring unit 120 in the form of a hose or a pipe.

The main line 101 serves to provide a part of the water flowing through the water supply pipe to the water pressure measuring unit 120 and the water quality measuring unit, and for this purpose, one end is connected to a setting part of the water supply pipe and the other end is connected to the water pressure line and the water quality. Branched to the line 111 , the water pressure line is connected to the pressure inlet, and the water quality line 111 is connected to the pressure reduction chamber 112 provided at the front end of the water inlet 113 .

The main line 101 may be installed in the ITO valve, the water valve, or the air valve, but is not limited thereto, and may be installed anywhere in the water supply pipe.

The water quality line 111 serves to provide water for water quality measurement to the decompression chamber 112 , and is branched from the main line 101 to communicate with the decompression chamber 112 .

The water pressure line serves to provide water for water pressure measurement to the water pressure inlet, and for this purpose, it is branched from the main line 101 and communicated with the water pressure inlet.

At this time, the water quality line 111 and the water pressure line do not necessarily have to be branched at the same point at the same time, and after the water quality line 111 or the water pressure line is branched from the main line 101 , the water pressure line or the water pressure line 111 is again It is free even if it is composed in a branched form.

The decompression chamber 112 serves to reduce the pressure of the water provided from the water quality line 111 and transfer it to the water quality inlet 113 , and for this purpose, it is provided between the water quality line 111 and the water quality inlet 113 . .

Since the water pressure of the water flowing in the water supply pipe is very high, it is difficult to properly measure the water when the water is directly provided to the turbidity measuring unit 110 . Accordingly, the decompression chamber 112 is provided in order to properly depressurize the water provided from the water quality line 111 and supply it to the water quality inlet 113 .

To this end, the decompression chamber 112 is configured to include a chamber housing 1120 having a hollow interior, and two partition walls installed to be spaced apart from each other inside the chamber housing 1120 , and thus to one side of the chamber housing 1120 . The water introduced through the communication-coupled water quality line 111 flows through the partition wall in turn and flows out through the water quality inlet 113 connected to the lower end of the other side of the chamber housing 1120 .

The partition wall is provided to be spaced apart from each other so as to be in close contact with the two opposing side surfaces and the bottom surface of the housing, so that the hollow part excluding the inner upper end of the housing is divided into three, and the hollow part of the housing divided by the partition wall is divided into a first hollow from one side to the other side. The part, the second hollow part, the third hollow part, and the inner upper end of the housing that are not separated by the partition wall are named the upper hollow part, and the partition wall separating the first hollow part and the second hollow part is formed by the first partition wall 1121 , When the partition wall separating the second hollow part and the third hollow part is called the second partition wall 1122 , the water provided from the water quality line 111 first falls into the first hollow part. At this time, since the water provided from the water quality line 111 is strongly sprayed, a large amount of air bubbles are generated, so a partition wall is provided to remove such air bubbles. Water that has fallen into the first hollow part gradually rises, overflows the first partition wall 1121 from the upper end of the first partition wall 1121, and flows into the second hollow part. Then, the water introduced into the second hollow part gradually rises, overflows the second partition wall 1122 at the upper end of the second partition wall 1122, and flows into the third hollow part. Finally, the water introduced into the third hollow part flows out through the water quality inlet 113 connected to the lower end of the third hollow part and is supplied to the water quality measuring part.

At this time, the first outlet 1123 is connected to the lower end of the first hollow part, the second outlet 1124 is connected to the lower end of the second hollow part, and the third outlet 1125 is connected to the other end side wall of the housing in communication with each hollow. It is configured to discharge part of the water introduced into the unit to the outside. If this is a structure in which all the water introduced from the water quality line 111 without an outlet flows out to the water quality inlet 113, the water quality line 111, the pressure reducing chamber 112, and the water quality inlet 113 are sealed. This is because, eventually, the pressure in the water quality line 111 and the pressure in the water quality inlet 113 become the same.

However, at this time, if the amount of water discharged to the outlet is too large, the water introduced into the first hollow may not overflow to the third hollow and thus may not flow out to the water quality inlet 113, and the amount of water discharged to the outlet may be too large. If the amount is small, eventually the inside of the chamber housing 1120 may be filled with water, and there may be a problem in that the pressure in the water quality inlet 113 is increased. Therefore, in the present invention, in order to solve this problem, the first outlet 1123, the second outlet 1124, and the third outlet 1125 are connected in communication with one outlet hose 1126, and the outlet hose 1126. A discharge valve 1127 is provided thereon, and a water level measuring unit 1128 is further provided on one side of the chamber housing 1120 . Accordingly, the controller receives the measured value from the water level measuring unit 1128, and when the measured value is detected by the water level measuring unit 1128, the discharge valve 1127 is opened after a set time at a set rate, and the discharge valve 1127 is opened. A discharge valve 1127 that allows water to overflow into the third hollow without filling the chamber housing 1120 using the time interval until the measured value is not detected in the water level measurement unit 1128 compared to the time point. ) can be estimated.

The control unit 200 receives the water pressure measurement value and the turbidity measurement value from the wireless transceiver of the measurement device 100 , accumulates and stores it in real time, and transmits it to the manager terminal 300 .

The control unit 200 first calculates information on which consumers can be supplied with water by using the distance and altitude values from the current measurement point to the rear end of the water pressure measurement value. The drain is usually provided at a higher position than the consumer, and since these drains are branched or continuous from the water supply pipe, the distance from the current measurement point to each drain, the height difference between the current measurement point and each drain, and the water pressure measurement value Using this, it is possible to calculate to which reservoir the water in the water supply pipe reaches, and to what extent the range of consumers receiving water from the reservoir is.

In addition, the control unit 200 estimates the turbidity measurement value at the customer compared to the turbidity measurement value at the current measurement point by using the turbidity measurement value. The turbidity of the water flowing in the water supply pipe tends to decrease gradually as the suspended matter is precipitated or diluted as it flows through the water supply pipe. Therefore, even if the turbidity measurement value at the current measurement point is higher than the reference value, if the expected turbidity measurement value at the customer is less than the reference value, the turbidity measurement value estimation at the customer is accurate because it cannot cause damage to the customer by forcibly forcing the water supply. should be done

However, it is impossible to derive the expected turbidity measurement value from the consumer only by measuring the turbidity measurement value at one measurement point using one measurement device 100 . Therefore, the present invention installs a plurality of measuring devices 100 at the rear end from a point where turbidity is expected to increase due to replacement work of water supply pipe, etc., and the water pressure measurement value and turbidity measurement value transmitted from each measurement device 100 is transmitted from the control unit 200 . The control unit 200 calculates the difference between the measured values for each measuring device 100 for each set time, and calculates the range of the consumer through which water reaches and the expected turbidity value in the corresponding consumer.

The control unit 200 transmits the water pressure measurement value, the turbidity measurement value, and the calculated turbidity measurement value in the range of the customer and the turbidity measurement value in the customer to the manager terminal 300 . This allows the site manager to perform the operation of the ITO valve or the water drain valve.

Since the determination of the operation timing of the ITO valve or the water drain valve using the measuring device 100 is made as a water pressure measurement value and a turbidity measurement value transmitted in real time, the inflow of a secondary pollutant in which the turbidity measurement value gradually decreases in time series rises again It is possible to identify the timing and take measures accordingly, which is a turbidity measurement using a portable simple measuring device, which has the advantage of responding to the inflow of secondary pollutants compared to the method of determining the operation timing of the ITO valve or the water drain valve.

On the other hand, the inflow of a pollutant is generally generated during replacement of a pipe or a new burial, but may also be introduced due to pipe breakage, water leakage, or the like. In this case, there is a problem that can be recognized only after the pollutants arrive at the reservoir and are detected by a sensor installed in the reservoir, or reach the consumer and file a complaint.

Therefore, in the present invention, a plurality of stationary measuring devices 100 and a plurality of mobile measuring devices 100 are provided to measure the inflow of a pollutant in real time to enable rapid response. The stationary measuring device 100 is always fixedly installed on the water supply pipe and transmits 24-hour measurement values to the control unit 200 , and the mobile measurement device 100 is a result of analyzing the measurement values of the stationary measuring device 100 , the inflow of pollutants It is temporarily installed as needed on this suspicious section and transmits the measured value to the control unit 200 .

To this end, in the present invention, a base measurement site in which the measuring device 100 is fixedly installed on the water supply pipe and a measuring point where the measuring device 100 is selectively temporarily installed as a movable type on the water supply pipe between the base measurement sites are designated. At this time, the fixed measurement device 100 installed in the base measurement site and the mobile measurement device 100 installed in the point measurement site are basically divided by the difference between whether the same measurement device 100 is always installed or temporarily installed, and separate The measuring device 100 having a function is not provided separately. The base measurement site is the point just before the water supply pipe is branched, for each set distance of the water supply pipe, or other points where turbidity measurement is required at all times, and the point measurement site is designated between these base measurement sites.

The control unit 200 always receives the measurement value from the base measurement site where the measurement device 100 is always installed. And, when the turbidity measurement value of the base measurement site is greater than or equal to the set value, a command is transmitted to temporarily install the measurement device 100 in the point measurement site at the rear end of the corresponding base measurement site. Thereafter, the control unit 200 receives the water pressure measurement value and the turbidity measurement value from the measurement device 100 of the base measurement site and the measurement device 100 of the point measurement site, and based on this, the range of consumers that water can reach and the expected value in the consumers Estimate the turbidity level. And, based on the turbidity measurement value for each set time of the base measurement site or the point measurement site, estimate the time when the expected turbidity value at the customer becomes less than the set value, generate water supply restart time forecast information, and post it on the web or in the manager terminal 300 send. The manager can predict the withdrawal time and water supply restart time of the measuring device 100 from the point measurement site by using the water supply restart time forecast information transmitted to the manager terminal 300, and accordingly, the manager does not reside in the point measurement site. It is possible to adjust the valve for withdrawal and water supply of the measuring device 100 from the measuring point at an appropriate time, so that the optimized operation of the management personnel is possible. In addition, when the secondary pollution source occurs and the water supply restart time forecast information is changed, the control unit 200 immediately transmits it to the manager terminal 300 so that the manager can refer to the dispatch. And, when the occurrence of the secondary pollution source is measured, the control unit 200 designates the restart time of the water supply as a time delayed by a set time compared to that of the primary pollution source, which means that the occurrence of the secondary pollution source may be a risk of a tertiary pollution source. This is because, when the occurrence of the secondary pollution source is detected, the installation of the measuring device 100 is maintained at the point measurement site for a longer period of time, and the restart time of water supply is further delayed.

Meanwhile, the control unit 200 accumulates and stores the measurement values at the base measurement site and the point measurement site. At this time, the accumulated measured values are stored by matching the measured values between the base measurement sites with the measured values of the base measurement sites. As the measured values matched and stored in this way, the error range is reduced as the measured values are accumulated, and the control unit 200 uses this to determine if the turbidity measurement value at one base measurement site is greater than or equal to the set value, matching and storing the measured value between the base measurement sites. Based on the measurement value, it is determined at which point measurement location the measurement device 100 should be installed. In addition, in this case, the matching of the measured values not only matches the measured values of the one base measurement site and the measuring point existing at the rear end thereof, but further subdivides the measured values of the one base measurement site into a plurality of sections, and each measured value It is possible to match and store the measured values of the point measurement points for each section. Through this, the control unit 200, when the measured value of the one base measurement site is equal to or greater than the set value, the measuring device 100 is placed on the point measurement site where a meaningful measurement value is expected based on the measurement value of the point measurement site matched to the corresponding measurement value section The measurement device 100 installation information is transmitted to the manager terminal 300 to install.

In addition, when matching and storing the measured value of the measuring point of the base to the measured value of the measuring point of the base, it is possible to further match and store more subdivided information. At this time, the matching information includes any one or more of the distance, altitude, diameter of the pipe, the presence or absence of branch points, the number of branch points, water pressure in the pipe, or the flow velocity between the set number of other base measurement points or point measurement points adjacent to the base measurement point or the point measurement point. It is measurement site relation information, and the control unit 200 determines a measurement site at a point where installation of the measuring device 100 is unnecessary based on the measurement site relation information accumulated over a set period. And, when a new pipe network is added, it is possible to determine which point of the new pipe network to designate a base measurement site or a point measurement site by extracting measurement site relationship information similar to that of the new pipe network from the stored data.

The present invention configured as described above includes a measuring device 100 installed on a water supply pipe to transmit measured values in real time, and a control unit 200 that accumulates and stores the transmitted measured values and transmits them to the manager terminal 300 . By including the configuration, there is an effect that the manager can know the operation time of the valve even if he is not resident on the site.

In addition, since the present invention measures turbidity and water pressure at the same time, there is an effect capable of predicting the range of water flowing through the current water supply pipe and the turbidity value in the consumer.

In addition, the present invention has an effect of minimizing the measurement error of the turbidity measurement value by minimizing the generation of air bubbles while decompressing the water flowing into the water quality measurement unit by providing a decompression chamber 112 having a three-division hollow part. .

In addition, in the present invention, a base measurement site in which the measuring device 100 is always installed and a point measuring site in which the measuring device 100 can be temporarily installed between the base measurement sites are designated, and only when an abnormal signal is generated in the base measuring site By being configured to install the measuring device 100 in a point measuring point associated with the corresponding base measuring point, there is an effect that can minimize the operation of the measuring device 100 .

In addition, the present invention matches and stores the measured value of the point measurement site with the measurement value of the base measurement site, and through this, it is determined whether the measuring device 100 should be installed at any point measurement site when an abnormal signal occurs at one base measurement site Therefore, there is an effect of optimizing the operation of the measurement device 100 .

In addition, the present invention has the effect of matching and storing the measurement site relationship information with the measurement value of the base measurement site, and through this, it is possible to reasonably determine at which point the base measurement site or the point measurement site should be installed when a new pipe network is added. .
