Description

WATER DISTRIBUTION MANAGEMENT SYSTEM CAPABLE OF DETECTING WATER LEAK}

The present invention relates to a water supply pipe network management system capable of leak detection, and more particularly, a data communication terminal device connected to the Internet to a tap water valve installed in a groundwater tap valve room or a tap valve box. The water pressure is measured at the dividing valve and transmitted to the server through the Internet without a separate device, and the transmitter identification number is stored in the hydraulic transmitter to be transmitted wirelessly with the water pressure. The present invention relates to a water supply network management system capable of detecting leaks that can detect leaks in a computer and manage a network.

In the water supply network, more than 12,000,000 water-reducing valves (gate valves or butterfly valves) are installed nationwide to separate the network into small or large compartments for each element. Most of the water supply network is buried underground, and a valve chamber (manhole shape) or a valve box (small tubular shape) is provided around the water discharge valve provided in the network to protect the water discharge valve and to provide easy access to the water discharge valve. Thus, the passage which provides the easiest access to the underground water supply network without digging out the ground is the valve chamber or valve box at the point of installation of the fresh water valve.

In Korean Patent Publication No. 10-5485511, a water leakage blocking and water flow radio having relays for receiving a radio signal propagated to the air and transmitting it to a mobile communication switch and for propagating a signal from the mobile communication switch to the air. A meter reading system is disclosed. 10-5485511 The invention relates to a system for wirelessly reading the water flow rate using the mobile communication network and the Internet, and to block leakage, and is installed in the water supply pipe flowing water to measure the flow rate according to the flow rate of the water supply pipe A metering device for generating an inspection meter data and detecting an abnormal state by detecting a flow rate of the water supply pipe, a valve control unit for opening and closing a valve installed in the water supply pipe in response to an input of a valve control signal, and reading the meter at predetermined intervals. At least one wireless meter reading unit including an RF transmission / reception control unit for receiving the meter data and the abnormal state data from a device and storing the meter data and the abnormal state data in an internal memory and converting the stored meter data and the abnormal state data into a CDMA message; Is connected to the mobile communication exchange through the Internet, and transmits and receives a transmission control protocol / Internet protocol to collect the data output from the wireless meter reading and storing in the database, and to respond to the data received from the meter reading and Leakage, characterized in that for opening and closing the valve of the water supply pipe in response to the valve opening and closing control signal transmitted from the control server is added to its own identification code, including a control server for transmitting the valve opening and closing control signal to the corresponding wireless meter reading unit A shutoff and flow rate wireless meter reading system is disclosed.

However, as described below, the present invention of No. 10-5485511 has a problem that it is difficult to supply power to each component (valve control unit, RF transmission / reception control unit, meter reading device), and the mobile communication service user and each communication unit for each RF transmission / reception control unit. There is a problem of signing up as an Internet service user and paying a regular communication fee, and providing water meter information or network information to a water supply manager who visited a leak site or suspected leak area. It may or may not be used.

First, look at the power supply problem. The valve control unit, the RF transmission / reception control unit, and the metering device according to the invention of No. 10-5485511 are installed in a manhole-shaped valve chamber or a small cylindrical valve box. In addition, the valve control unit of the present invention No. 10-5485511 opens and closes the valve installed in the water supply pipe in response to the input of the valve control signal, the RF transmission and reception control unit receives the meter reading data and abnormal state data from the meter reading device at a predetermined period It stores in the internal memory and converts the stored metering data and abnormal state data into a CDMA message form and transmits it to the repeater, and the metering device is installed in the water supply pipe through which water flows to measure the flow rate according to the flow rate of the water supply pipe. It generates the meter reading data and detects the abnormal state by detecting the flow rate of the water pipe. Therefore, these valve control units, RF transmission and reception control units and meter reading devices consume a lot of power. Particularly, the meter reading device continuously measures the flow rate according to the flow rate of the water supply pipe, generates meter reading data corresponding thereto, detects the flow of the flow rate of the water supply pipe, detects an abnormal state, and transmits it to the RF transmission and reception control unit. Since the meter data and the abnormal state data are periodically converted into a CDMA message and transmitted to the repeater, the data size of the transmitted data is large and the number of transmissions is frequent, which consumes a lot of power. However, it is difficult to draw utility power (cast) from the outside in the valve chamber or the valve box. One valve room or valve box installed in the water supply network is installed for each distillation valve (over 12,000,000 nationwide) .When commercial power is supplied to all valve rooms or valve boxes, a transformer and a power billing charge are applied to lower the transmission voltage. In order to install the electric power meter separately and to carry out the electric wires to every valve room or the valve box, the cost is excessively excessive and the inside of the valve room or the valve box is frequently flooded in rainy weather, which causes electric leakage and electric shock. This is because there is a risk of an accident. Therefore, a battery can only be used as a power supply device for the valve control unit, the RF transmission and reception control unit, and the meter reading device. However, since these devices consume a lot of power, even if a large capacity battery is used, it must be replaced at any time. However, replacing a battery installed in a valve chamber or a valve box in the underground is a very expensive and laborious task. There is this.

As in the invention of No. 10-5485511, the RF transmission / reception control unit of the wireless meter unit receives the meter data and the abnormal state data from the meter at a predetermined cycle and stores the stored meter data and the abnormal state data in the internal memory, and stores the stored meter data and the abnormal state data in the form of a CDMA message. Converting the data into the repeater, connected to the mobile communication switch via the Internet, the control server transmits and receives a transmission control protocol / Internet protocol, collects the data output from the wireless meter reading unit, and stores the data in the database; In order to transmit data and valve opening / closing control signals for responding to data received from the meter reading unit to the corresponding wireless meter reading unit, each RF transmitter / receiver control unit needs to subscribe to a mobile communication service provider and receive a subscriber number. Communication for each RF transceiver Fees must be paid regularly. Therefore, when using the water leakage blocking and flow rate wireless meter reading system of the 10-5485511 invention, it is difficult for the water service provider to bear the cost.

Water supply managers identify areas where pipes are aging in the water supply network, so they often visit site for suspected leaks and carry out on-site inspections. In the invention of No. 10-5485511, waterworks that visit the site and check for leaks The disadvantage is that it does not provide any information to the administrator.

The present invention has been made to solve the problems of the above-described leakage blocking and water flow rate wireless meter reading system, the first problem to be solved by the present invention is to minimize the power consumption of the hydraulic pressure measuring radio transmitter installed in the valve chamber or valve box In order to provide a water supply network management system that can detect leaks that can be used for a long time without changing batteries while using batteries.

The second problem to be solved by the present invention is a water supply that can detect leaks in the water supply office through the mobile communication network and the Internet without subscribing to a mobile communication service provider or paying a communication fee for each RF transmission / reception control unit installed in the valve. It is to provide a pipe network management system.

The third problem to be solved by the present invention is to visit the area where the water supply manager suspects leakage, check the water pressure of the corresponding area by the smart phone possessed by the water supply manager in the field to detect the leak, and confirm the pipe network management information to take countermeasures. To provide a water supply network management system that can take.

The fourth problem to be solved by the present invention is to check the water pressure and pipe network management information measured by the pressure measurement wireless transmitter with a voice on the smartphone without installing a text speech conversion engine (TTS) on the pressure measurement wireless transmitter or smartphone It is to provide a water supply network management system that allows water managers to detect leaks and take countermeasures in the field even during the time (between 2 and 5 am).

The fifth problem to be solved by the present invention is the pipe network management information of the dilution valve and the piping around the dilution valve (distillation valve manufacturing year, dilution valve manufacturer, diameter, opening and closing rotation speed, the current rotation direction rotation or opening direction rotation, supervisor Name, name of supervisor or name, name or name of the original city contractor, name or name of subcontractor, name of construction year, completion date, position of water valve, nature of pipe (water pipe, drain pipe, water supply pipe, inlet pipe), type of pipe (cast iron pipe, PE pipe, etc.) , The nature of the valve (intermediate valve, branch pipe, air valve, discharge valve, etc.), and the nature of the branch pipe when the valve nature is a branch pipe (1 male 1 type T-type tube + type of capillary; The type, triangular T-shaped tube + type of mother tube, the type of sperm tube + mother tube to be connected, and the type of manhole (648mm, 265 manhole, etc.) can be checked at any time by the hydraulic measuring radio transmitter installed in the water valve. Information on valve compartment The present invention provides a water supply network management system that can be changed externally without entering a valve or a valve box.

The sixth problem to be solved by the present invention is to provide a water supply network management system that can determine whether or not leaking water by accurately measuring the water pressure after discharging the air bubbles or air even if the air flowing through the pipe contains air bubbles or air have.

The first to fifth objects of the present invention described above are provided with a transmitter identification number and installed in the dilution valve, so that the battery power is supplied only when the valve key is impacted to measure the water pressure and measure the measured water pressure together with the transmitter identification number. Battery-powered hydraulic transmitters for transmitting to phones; After receiving the transmitter identification number and the measured water pressure from the water pressure measuring radio transmitter, and transmits to the following server, receiving the dilution valve management number, pipe network management information, voice file and text data about the water pressure from the server, Smart phone to output the divisor valve management number and pipe network management information and measured water pressure by voice or screen; The dilution valve management number matched to the transmitter identification number, the pipe network optical information matched to the distillation valve management number, measured water pressure and measurement date and time database, and after receiving the transmitter identification number and the measured water pressure from the smartphone and stored in the database A server for generating a voice file for the dilution valve management number, the pipe network management information, and the measured water pressure to the smartphone, and transmitting the text data for the distillation valve management number, the pipe network management information and the measured water pressure to the smartphone; And a client computer which displays a dilution valve management number of the server database, pipe network management information matched thereto, measured water pressure, and a measured date and time on a monitor so that an administrator can determine a leak due to a change in water pressure. Detected by a water supply network management system that can be detected.

The sixth problem of the present invention described above is that the water pressure measurement radio transmitter has a water inlet formed therein and a water distribution space for dispensing water introduced from the water inlet is continuously formed with the water inlet. And a hydraulic pressure gauge outer cylinder having a first air discharge port formed at a side thereof, and an air discharge valve assembled inside the hydraulic pressure gauge outer cylinder so as to be disposed above the water distribution space of the hydraulic pressure gauge, and having a lower end exposed to the water distribution space. It includes a hydraulic pressure gauge core having a second air outlet for connecting the discharge air valve and the first air outlet of the hydraulic pressure gauge, and a pressure sensor installed in the hydraulic pressure core and the lower end is exposed to the water distribution space It is solved by configuring.

According to the present invention, although the hydraulic pressure measuring radio transmitter installed in the dilution valve is driven by the battery, the power of the battery is supplied only when the valve key is impacted to measure the hydraulic pressure and transmit the measured hydraulic pressure. In addition to this, since only the transmitter identification number is transmitted to the smartphone without any other data along with the measured water pressure, the data transmission power is small to minimize the data transmission power, so that the hydraulic pressure transmitter can be used for a long time without replacing the battery. In addition, since the received water pressure and transmitter identification number transmitted from the water pressure measurement radio transmitter are received by a smartphone owned by the administrator and transmitted to the server through the wireless Internet, each mobile water service transmitter installed in the valve can be separately subscribed or No need to pay communication fee The administrator visits the leak suspected area and receives the measured water pressure and pipe network management information from the server by his smartphone at the site, checks the water pressure of the corresponding area, detects the leak, and checks the pipe network management information to take countermeasures. This enables quick and accurate leak detection and countermeasures, and enables the smartphone to monitor the water pressure and network management information measured by the hydrostatic wireless transmitter without installing a text speech conversion engine (TTS) on the hydrostatic wireless transmitter or smartphone. The water manager can detect leaks in the field and take countermeasures even at dawn (between 2 and 5 o'clock in the morning), and the network management information of the piping around the water valve and the water valve (year of manufacture of the water valve, The distillation valve manufacturer, diameter, open / close rotation speed, current lock direction rotation or open direction rotation, supervisor's name, Name or name of the company, name or name of subcontractor, name or name of subcontractor, date of completion, location of water valve, nature of pipe (water pipe, drain pipe, water supply pipe, inlet pipe), type of pipe (cast iron pipe, PE pipe, etc.), valve Nature of the valve (middle valve, branch pipe, air valve, discharge valve, etc.) The three-T-shaped tube + type of mother tube, the type of sperm tube + mother tube to be connected), the type of manhole (648mm, 265 manhole, etc.)) can be checked at any time by applying a shock to the hydraulic measuring radio transmitter installed in the dividing valve. Since the management information can be changed on the client computer connected to the server, the water pipe network can be managed very efficiently. In addition, according to the present invention, even if bubbles or air is included in the water flowing through the pipe has an effect that can determine whether the water leakage by accurately measuring the water pressure after discharging the bubbles or air.

And the client computer 400 to allow the administrator to determine the leak due to the water pressure fluctuation.

As can be seen with reference to Figures 2 and 6, the hydraulic pressure measuring unit 100 detects the water pressure and outputs an electrical signal (current or voltage) proportional to the water pressure and the pressure A hydraulic pressure measurement transmitter 57 converts the output signal (current or voltage) of the sensor 53 into a digital value and wirelessly transmits it to the smartphone 200 together with the transmitter identification number. The hydraulic pressure measuring transmission unit 57 is an analog-to-digital converter (A / D converter) 65 for converting an analog electric signal output from the pressure sensor 53 into a digital value, and the triggering of the impact sensor 67 ( Receives a triggering signal and supplies power to the pressure sensor 53, thereby turning on and reading the digital value of the water pressure from the analog-to-digital converter (ADC) 65 and storing the receiver identification number stored in the memory 63.

And a shock sensor 67 for inputting a triggering signal to the microcontroller unit 59 when the impact is applied to switch the microcontroller unit 59 from the standby mode to the operation mode. ).

The radio frequency transceiver 61 is a radio transmitter using a Bluetooth protocol or a Zigbee protocol to which a transmitter identification number is assigned. That's because every smartphone includes a wireless transmitter that uses the Bluetooth protocol or Zigbee protocol to communicate wirelessly with it. The Bluetooth wireless transmitter adopts Bluetooth that can transmit and receive data by being compatible with Bluetooth installed in a smartphone.

The shock sensor 67 provides a triggering signal to the microcontroller unit 59 by being electrically closed or opened in an instant when an impact by a valve key (117 of FIG. 5) is applied. The impact sensor 67 may be provided with a required impact by hitting the key box 119 of the valve key 117 against the hydraulic transmitter 100.

As shown in FIG. 6, a trigger switch reacting by light such as a CdS cell 69 or a trigger switch reacting by a magnetic field such as a reed switch 71 may be used as an equal replacement means for the impact sensor. It may be. As shown in FIG. 5, when the CdS cell 69 is used, light required for operation may be applied using the flash 127. In addition, a magnet 123 is driven into the lower surface of the key box 119 of the valve key 117 and the required magnetic field can be applied to the reed switch 71 by bringing the key box 119 close to the hydraulic pressure transmitter 100. have.

The impact sensor 67, the CdS cell 69, and the reed switch 71 may be selectively or individually used, but as shown in FIG. 6, the microcontroller unit 59 may be connected to each other in parallel. To provide a triggering signal.

As shown in Figures 2 to 5, the hydraulic pressure measuring transmitter 100 is installed in the water separator valve. The dividing valve includes a valve body 107 and a valve cover 103 coupled to the upper portion of the valve body 107. The hydraulic measurement wireless transmitter according to the present invention includes a reinforcement 105 in the valve cover 103. It is possible to form, and install the hydraulic pressure transmitter 100 in this place. In this way, when the hydraulic transmitter 100 is installed on the valve cover 103 instead of the valve body 107, it is possible to measure the hydraulic pressure in a state where the air discharge is ensured (at the point where the air is the highest). As a result, it is easy to apply an impact or the like outside the ground of the manhole or the valve box, and there is an advantage of receiving wireless data on the ground without interference of electromagnetic waves by the valve body 107 made of metal.

As shown in FIGS. 3 and 4, a female threaded hole (tab) penetrates the reinforcement bar 105 formed in the valve cover 103 to reach the inside of the valve cover, and a cock 101 having an on-off valve built therein. In this cock 101, it is preferable to install the hydraulic pressure measuring transmitter 100 according to the present invention. This is because the cock 101 can be shut off when the hydraulic transmitter 100 fails or is replaced.

As shown in FIG. 5, the dilution valve according to the present invention according to the present invention may be installed in a valve box of a lower ground of a narrow iron rod 129 that cannot be entered by a person, but a person may have It can also be installed inside a manhole that can be retracted. However, the water supply manager can always receive the water pressure and the handset identification number by the smart phone 200 from the ground, and can receive voice files and text data about the water pressure and pipe network management information from the server 300.

As can be seen with reference to Figures 7 to 9, the hydraulic pressure measuring transmitter 100 according to the present invention is a hydraulic pressure gauge outer cylinder (1, 19) consisting of a hydraulic pressure gauge lower outer cylinder (1) and a hydraulic pressure gauge upper outer cylinder (19). And a hydraulic pressure gauge core 27 assembled inside the hydraulic pressure gauge outer cylinders 1 and 19. The lower portion of the hydraulic gauge lower outer cylinder (1) is formed with a connection pipe 13 is screwed to the pipe or a dilution valve, etc., the flange 17 and the body 23 is formed on the upper connection pipe (13). An inlet 15 is formed in the connection pipe 13. The body 23 of the lower outer cylinder 1 is provided with a water distribution space 11 which is wider than the inlet 15 so as to distribute water introduced from the inlet 15.

A first air outlet 5 is formed at the side of the body 3 of the upper outer cylinder 19. The inside of the upper outer cylinder 19 is provided with a step 9 for setting a limit to which the hydraulic pressure core 27 can enter upward when assembling the hydraulic pressure core 27 to the upper outer cylinder 19. By this step 9, the board | substrate 58a installation space of the hydraulic pressure measurement transmission part 57 is ensured by the fixed height on the hydraulic-pressure core 27 upper part. As shown in FIG. 7, the inner wall of the upper outer cylinder 19 forms a female screw, and the outer wall of the hydraulic core 27 forms a male screw coupled thereto so that the upper outer cylinder 19 and the hydraulic core 27 are formed. Can be screwed together. However, when the sealing is sufficiently performed by interfering an O-ring between the upper outer cylinder 19 and the hydraulic pressure core 27 or applying an adhesive, the internal thread and the hydraulic pressure gauge core 27 of the inner wall of the upper outer cylinder 19 are provided. The external thread of the outer wall may be omitted. In addition, a groove 7 is further formed on the inner wall of the upper outer cylinder 19 to the height of the first air outlet 5 to easily connect the flow path with the second air outlet 37 formed in the hydraulic core 27. You can also The outer surface of the lower outer cylinder (1) or the outer surface of the upper outer cylinder (19) may be further formed on each surface for screwing the tool hook. The upper outer cylinder 19 may be provided with a light emitting means in order to allow the water supply manager to easily detect the hydraulic pressure measuring transmitter 100 from the outside of the valve chamber or the valve box. The light emitting means may include a fluorescent material in the molding material of the upper outer cylinder 19, combine a phosphor prepared separately in the upper outer cylinder 19, or combine a light emitting lamp such as an LED.

As can be seen with reference to FIGS. 7 and 9, the hydraulic pressure gauge core 27 is disposed inside the hydraulic pressure gauge upper outer cylinder 19 so as to be disposed above the water distribution space 11 of the hydraulic pressure gauge lower outer cylinder 1. Is assembled on. At this time, the lower end of the hydraulic core 27 is assembled in close contact with the upper end of the body 23 of the hydraulic outer cylinder (1). The pressure sensor 53 having a lower end exposed to the water distribution space 11 is coupled to the hydraulic gauge core 27. In addition, the hydraulic core 27 is provided with an air discharge valve 41 adjacent to the pressure sensor 53, the lower end of which is exposed in the water distribution space 11. To this end, a first tab 33 in which the connecting pipe 55 of the pressure sensor 53 is screwed is formed in the body 29 of the hydraulic gauge core 27, and a pressure sensor is formed on the first tab 33. The hollow 31 to which the body of 53 is assembled is formed. In addition, the body 29 of the hydraulic pressure gauge core 27 has a second tab 35 which is assembled with the connecting pipe 49 of the air discharge valve 41 adjacent to the first tab, and the second tab 35. ) Is formed a second air outlet (37) for forming a flow path continuous with. As shown in FIG. 9, the second tap 35 is provided with an air discharge valve 41 including an O-ring 39, an operation port 43, and a ball support 45. The operating port 43 is not lifted by air, but is lifted by water with water pressure and has a weight that comes into close contact with the O-ring 39. A flow path 47 is formed at the center of the sphere support 45, and a connection pipe 49 screwed with the second tab 35 of the hydraulic gauge core 27 is formed at the sphere support 45. In addition, the upper end of the connecting pipe 49 is formed with a plurality of long holes 51 in the longitudinal direction. The first air discharge port 5 of the hydraulic pressure gauge upper outer cylinder 19 and the second air discharge hole 37 of the hydraulic pressure gauge core 27 are assembled with a hydraulic pressure gauge upper cylinder 19 and a hydraulic pressure gauge core 27. In the state to form an air flow path connected to each other. The external shape of the pressure sensor 53 may employ a pressure sensor 53 of various structures in addition to the structure shown in the drawings, and according to the external shape of the pressure sensor 53 and the first tab 33 formed in the hydraulic pressure gauge core 27 and The shape and size of the hollow 31 also vary.

As shown in FIG. 8, the hydraulic installation core 60 further includes a battery installation hole 60 into which the battery 58b of the hydraulic measurement transmission unit 57 is inserted.

Referring to FIG. 9, when air or air bubbles are mixed in the water received in the water distribution space 11 through the inlet 15, the flow path inside the support 45 of the air discharge valve 41 is shown. Passing through the 47 and the long hole 51 is discharged through the second air outlet 37 and the first air outlet (5). At this time, since the air or air bubbles are light, the operation port 43 cannot be pushed up. When air or air bubbles are not mixed in the water obtained in the water distribution space 11 through the inlet 15, the water pushes the operating port 43 upward by water pressure to closely contact the O-ring 39. Therefore, there is no leakage of water and only air or bubbles escape. By configuring the hydraulic pressure transmitter in this manner, even when bubbles are contained in the water, it is possible to measure the exact hydraulic pressure to the extent that it is possible to determine whether there is a leak.

As can be seen again with reference to Figure 1, the program executed in the hydraulic pressure measurement transmitter 100 is a hydraulic pressure measurement module for supplying power to the pressure sensor by detecting a shock and measuring the hydraulic pressure, transmitter identification number and measurement It includes a wireless transmission module for transmitting the water pressure to the smartphone.

The server execution program includes a module for generating, inputting, retrieving, or modifying pipe network management information text data matched with a dilution valve control number. The server is equipped with a TTS (Text to Speech) engine.

As described above, according to the present invention, although the hydraulic pressure measuring transmitter installed in the dividing valve is driven by the battery, the power of the battery is supplied only when the valve key is impacted to measure the hydraulic pressure and transmit the measured hydraulic pressure. In addition to the low power, the transmitter transmits only the transmitter identification number to the smartphone without any other data with the measured water pressure. Since the transmission data is small, the data transmission power can be minimized. It can be used, and receives the measured water pressure and transmitter identification number sent from the pressure measuring radio transmitter from the smartphone owned by the administrator and transmits it to the server through the wireless Internet, so that each hydraulic measuring radio transmitter installed in the valve is separately provided to the mobile communication service provider. No need to sign up or pay for communication The water supply manager visits the suspected water leak area and receives the measured water pressure and pipe network management information from the server by his smartphone at the site, checks the water pressure of the corresponding area, detects the leak, and checks the pipe network management information to respond. Measures can be taken to enable quick and accurate leak detection and countermeasures, and to monitor the water pressure and network management information measured by a hydraulic transmitter without a text speech conversion engine (TTS) installed on the hydraulic transmitter or smartphone. By checking the voice on the smartphone, the water manager can detect leaks in the field and take countermeasures even at dawn (between 2 and 5 o'clock in the morning). You can check at any time by applying an impact to the installed hydraulic pressure transmitter, The ability to change from a client computer or smartphone connected to the server, there is an effect that can manage the water distribution network very efficiently.
