Description

Leakage prevention and flow rate wireless meter reading system and control method {SYSTEM FOR TELEMETERING WIRELESS HAVING WATER LEAKAGE CUTOFF AND METHOD SAME}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wireless remote meter reading system. More particularly, the present invention relates to a system for automatically detecting a leak and a metering flow for automatically detecting a leak of water supplied to a water supply pipe and controlling a valve of the main pipe and metering and metering the amount of water in the main pipe. It is about.

Typically, for supply to purified water, such as drainage, industry, large buildings and homes are supplied through pipelines such as water pipes, drain pipes, drain pipes and drain pipes having a very large diameter. In other words, water is supplied from the water purification plant to the drainage basin through the water pipe, and water is supplied from the drainage basin to the large residential complex where a large number of prisoners are collected. In addition, water is supplied to the small housing complex through the drainage pipe through the drainage pipe of the large housing complex. This will be described below with reference to the drawings.

1 is a view for explaining a wide water supply block system. Referring to Figure 1, between the water treatment plant 10 and the reservoir 14 located in the indirect water supply block 12 (or pressurized water supply area) is connected through a large water pipe 16. The drainage 14 and the water supply block 18 (for example, a large unit house) are connected through the drainage pipe 20. The diameter of the drain pipe 20 is smaller than the diameter of the water pipe 16 is used. At this time, the water supply pipes 16 and the water distribution pipe 20 are provided with flow meters 22, 24, and 26 at appropriate positions. These flow meters 22, 24 and 26 provide useful information for metering the flow rate of water flowing through the water supply pipe, the drain pipe, and the drain pipe, and for detecting leaks in the pipe.

For example, a water pipe 14 connected between a water treatment plant 10 and a drain 14 and a flow meter 22, 24 and 26 installed between the drain pipe, the drain pipe and the drain pipe between the drain 14 and the drain pipe 20 are used to determine the amount of water flowing in. Weigh and indicate numerically. Examples of such flow meters include various types such as ultrasonic type, differential pressure type, area type, and the like.

As described above, if the meter reading information of the flowmeter installed between the plurality of pipelines can be grasped, and if it is possible to determine whether or not leaks of the pipelines located between the flowmeters, the leaked pipelines can be repaired or replaced to prevent leakage. It is a well known fact.

Most of the flowmeters adopted in the water supply block system simply measured the flow rate flowing into the water supply line and only displayed the information, and could not detect the leak in the pipe line automatically. The conventional method for detecting whether a leak occurs in a pipeline installed with a flowmeter is mainly used to calculate the value of the two flowmeters and the amount of water consumed therebetween and detect them as the difference.

For example, in FIG. 1, in order to detect whether there is a leak in the drainage pipe 20 between the flowmeters 24 and 26l, the reading amount of the flowmeters 24 and 26l and the average consumption of the water supply blocks 18i, 18j and 18k are subtracted. It is a way of recognizing a leak when it leaves. However, in the conventional leak detection method as described above, the leak detection is not performed in real time by using a separate leak detector or manually reading and calculating the values of the flow meters. Therefore, leak detection and valve repair due to leakage, replacement of the water pipe was not smoothly consumed a large amount of water and water management was not smooth.

In addition, even if the occurrence of the leak is detected, there is a problem that takes a long time to shut off the leak by manually opening and closing the valve installed in the large water supply pipe.

Accordingly, an object of the present invention is to provide a leakage blocking and flow rate wireless meter reading system and a control method thereof to detect leakage of a water pipe in real time in a blocked water supply system so that the leakage can be blocked in the shortest time.

Another object of the present invention is to wirelessly transmit the meter reading data of the flow meter to the waterworks control center by a simple method to detect the leakage of the water supply pipe in the shortest time, and the water leakage cutoff and the flow rate wireless that can control the opening and closing of the valve of the water supply pipe remotely The present invention provides a metering system and a control method thereof.

Write down including an RF transmitting and receiving control unit One or more wireless meter reading unit; It is connected to the mobile communication exchange through the Internet, transmits and receives a transmission control protocol / Internet protocol (hereinafter referred to as "TCP / IP"), collects the corresponding data, stores it in a database, and stores a valve. It includes a control server for transmitting and closing the control signal and various response data to the wireless meter reading unit, the wireless leak leakage blocking and water flow rate wireless meter reading system and its control method is added to its own identification code from the control center to open and close the valve It is characterized in that the valve of the water supply pipe is opened and closed in response to the control signal.

The control server in the leakage blocking and water flow rate wireless meter reading system configured as described above is always in the neighboring indirect water supply block from the value of the difference between the wireless meter reading data transmitted at predetermined intervals from a plurality of wireless meter reading parts positioned at predetermined intervals in the water supply pipe. When the consumption value is reduced by subtracting the consumption value, the valve control signal is transmitted to the wireless meter reading part to automatically open and close the valve located in the wireless meter reading part so that the leak can be repaired quickly.

2 is a block diagram of a leak diagnosis and flow rate wireless meter reading system according to an embodiment of the present invention. Referring to FIG. 2, the water leakage blocking and water flow rate wireless meter reading system according to the present invention is installed in the water supply pipe 113 through which water flows to measure the flow rate according to the flow rate of the water supply pipe to generate meter reading data corresponding thereto, and the flow rate of the water supply pipe. A meter reading device 114 for detecting an abnormal state by detecting a flow of water, a valve control unit 118 for opening and closing a valve installed in the water supply pipe in response to an input of an opening / closing control signal, and meter reading data and abnormal state data from the meter reading device at predetermined intervals. And a wireless meter reading unit 102i configured as an RF transmission / reception control unit 116 for receiving and storing the data in an internal memory and converting the stored meter reading data and the abnormal state data into a CDMA message. At this time, each of the forward or backward directions of the water pipe 113 where the wireless meter reading unit 102i (where i is a natural number including 0) is installed to the input of the valve control signal output from the valve control unit 118 in the wireless meter reading unit 102i. The solenoid valve 115i is opened or closed in response.

The wireless meter reading data output from the wireless meter reading unit 102i is transmitted / received in a transmission format of cellular or code division multiple access (CDMA). Of course, the wireless meter reading unit 102i has a unique call code like CDMA communication terminals, and is configured to enable mutual call and communication.

The meter data information wirelessly transmitted from the wireless meter reading unit 102 is transmitted to the repeater 104 forming a commercial CDMA communication network. The repeater 104 receives a radio signal propagated to the air, transmits the signal to the mobile communication switch 106, and propagates the signal from the mobile communication switch 106 to the air, for example, a wireless meter reading unit shown in FIG. At least one repeater 104 for transmitting to 102i and another CDMA terminal (mobile phone) or the like.

The repeater 104 is connected to a mobile communication switch 106 composed of a control station (Base Station Center) and a mobile switching center (Mobile Switching Center) and is given a unique call sign, for example, between the mobile phone and the wireless meter reading unit 102i Form a communication channel. Note that in the present invention, such CDMA communication is not described in detail. In order to carry out the present invention, wireless metering data transmitted from the wireless metering units 102i are transmitted to the control server 110 via the Internet 108. Communication between the mobile communication switch 106 and the control server 110 transmits and receives TCP / IP, the control server 110 collects the corresponding data, stores the data in a database, and transmits a valve opening / closing control signal and various response data to the wireless meter reading unit 102i. .

The control server 110 detects a unique identification code of the wireless meter reading unit 102i included in the wireless meter reading data received through the repeater 104, the mobile communication switch 106, and the Internet 108, and stores the wireless meter reading unit 102i, that is, the wireless meter reading database of the flow meter. Will be updated. At this time, the control server 110 receives the wireless meter reading data of the wireless meter reading unit 102 and the neighboring wireless meter reading unit 102i to calculate the difference between the meter reading data. Thereafter, the control server 110 is a value within a preset range by comparing the value of the always average consumption flow rate of the water supply block located between the two wireless meter reading units 102 and 102i with the calculated difference of the reading data. In this case, normal treatment. At this time, the value of the preset range should be set in consideration of the minimum leakage caused by the seam of the water pipe (or water pipe).

If the difference between the meter reading data and the average value of the average water consumption of the water supply block between the two flowmeters is out of the preset range, the control server 110 determines that a leak has occurred in the water supply pipe between the wireless meter 102 and 102i. Then, the valve closing control signal is transmitted to the RF transmission / reception control unit 116 in the wireless meter reading unit 102 and 102i via the Internet 108, the mobile communication switch 106, and the repeater 104. In this case, the RF transmitter / receiver controllers 116 in the wireless meter reading units 102 and 102i supply the valve closing driving signal to the valve control unit 118 by the received valve closing control signal, and the valve control unit 118 is positioned around the valve 115 as shown in FIG. 2. The 115i is closed to block the inflow of water into the water pipe. In addition, the control server 110 transmits a leak message of the water pipe to the water supply terminal 112 connected by TPC / IP or a dedicated line to enable repair and replacement of the water pipe leaked.

As described above, the leakage blocking and water flow rate wireless meter reading system according to the present invention is a flow meter, that is, the meter reading data transmitted wirelessly by meter reading in the wireless meter 102 installed in the water pipe, the control server 110 through the repeater 104, the mobile communication switch 106 By receiving from, the flow rate of the corresponding water pipe (water treatment plant or drainage station) can be remotely recognized, and the valve can be automatically detected by detecting the leakage of the corresponding water pipe by calculating the average inflow of the water supply block and the reading data values of neighboring flow meters. By controlling, leaks can be repaired more quickly. This operation will be made clearer by the following description.

Of the above configurations, the repeater 104, the mobile communication switch 106, the Internet 108 and the control server 110 forms a CDMA communication channel to collect data transmitted from the wireless meter reading unit 102 and transmits a control signal (response signal) corresponding thereto. It should be recognized that it corresponds to the control unit that updates meter reading data.

FIG. 3 is a block diagram illustrating a specific example of the wireless meter reading apparatus shown in FIG. 2. Referring to FIG. 3, the meter reading device 114 monitors the operation state of the flow meter reading unit 116 and the wireless meter reading unit 116 for measuring the flow rate of water flowing into and out of the water supply pipe and outputting it as digital data. Or an abnormality detection unit 118 for detecting a state of the water supply pipe, for example, a blockage of the fluid by foreign matter, and the like. The meter reading data and the abnormality detection data output from the flow rate detection unit 116 are output to the control unit 120.

The controller 120 outputs and displays the input meter reading data and the abnormality detection data to the display unit 122, converts the data into a data format including a unique call code, and transmits the read data to the repeater 104 through the CDMA modulator 124 and the RF module 126. In this case, the CDMA demodulator 124 and the RF module 126 modulate the meter reading data or the abnormality detection data output from the control unit 120 in a CDMA format, and the RF module 126 upconverts the input modulation data to a CDMA frequency band and waits. To propagate. That is, it converts to the cellular or PCS communication frequency band and transmits to the repeater 104 side of FIG.

In addition, the RF module 126 receives data received through the mobile communication switch 106 and the repeater 104 from the control center 110 of FIG. 1, for example, a valve control signal, a metering request message, an acknowledgment signal, and the like. Data to be input is input to the controller 120. Here, the meter reading request message means a message for receiving the flow meter reading data of the flow meter, that is, the wireless meter reading units 102 periodically or at a preset time. In addition, the confirmation signal is a response message indicating that the reception of the meter reading data when the flow meter reading data of the water supply pipe from the wireless meter reading unit 102.

When the control unit 120 receives the valve control signal through the RF module 126 and the CDMA transformer 124, the control unit 120 analyzes the valve control signal to open and close the valve 115 installed in the water supply pipe 113 through the valve driver 118 to control the flow rate of the water supply pipe 113. To control the flow.

Figure 4 is a flow chart of the operation of the leak diagnosis and flow rate wireless meter reading system according to the preferred time of the present invention.

Hereinafter, a preferred embodiment according to the present invention will be described in detail with reference to FIGS. 1 to 4.

When the leakage blocking and water flow rate wireless meter reading system configured as shown in FIG. 2 is operated, the meter reading device 114 in the wireless meter reading unit 102 detects the flow of the flow rate in the water supply pipe 113 and generates digital meter reading data corresponding to the inflow / outflow of water. The abnormal state is detected by detecting the state of the flow rate of the water supply pipe 113. For example, the flow meter reading unit 116 of FIG. 3 reads the flow rate of water flowing into / out of the water supply pipe 113 and provides the corresponding data to the control unit 120. The abnormality detecting unit 118 detects an abnormal state in the water supply pipe 113. Here, the abnormal state is the output of the sensor for detecting the blockage of the water supply pipe 113, for example, foreign matters that impede the flow of the flow, and the low battery, empty tube state, water supply pipe of the wireless meter reading unit 102. Means the output of the sensor for detecting the decomposition of the freezing wave, the wireless meter reading unit 102 and the like can be used as it is currently used in this field.

The meter reading data and the abnormal state detection data as described above are provided to the control unit 120 in the RF transmission / reception control unit 110. In this case, the controller 120 reads the meter reading and abnormality detection data in step 302 of FIG. 4 and stores the read meter and abnormality detection data in the memory 128 in step 304. The controller 120 analyzes the received data and searches whether an abnormal condition has occurred.

If an abnormal condition occurs as a result of the search, the controller 120 up-converts the abnormal detection data stored in the memory to the CDMA frequency band through the CDMA modulator 124 and the RF module 126 in step 308 of FIG. In step 312 of FIG. 4, it is checked whether a response message is received through the 126 and the CDMA modulator 124. At this time, upconverting to the CDMA frequency band means converting data into a frequency band used as a cellular or personal communication service (PCS) communication scheme so as to transmit and receive data to a preset counterpart. The communication of the CDMA frequency band uses a method that is already widely used, and includes its own code of the wireless meter reader 102.

The data transmitted to the repeater 104 is input to the control server 110 through the mobile communication switch 106 and the Internet 108. The control server 110 analyzes the received data to recognize the unique code of the wireless meter reading unit 102 and the contents of the abnormality detection data. For example, the control server 110 analyzes the received data to analyze and recognize the position and abnormality of the wireless meter reading unit 102.

As a result of analysis, if it is determined that the abnormal condition is caused by a fatal abnormality in the water supply pipe 103, for example, the water pipe is clogged due to freezing, foreign substances, etc., the control server 110 transmits and displays the corresponding message to the terminal 112 of the waterworks office. At the same time, the corresponding response code, for example, a valve closing or valve opening driving signal is transmitted to the corresponding wireless meter reading unit 102 through the Internet 108. The response code transmitted to the Internet 108 is transmitted to the wireless meter reading unit 102 through the mobile communication switch 106 and the repeater 104, and the RF module 126 and the CDMA transformer 124 in the wireless meter reading unit 102 transmit the received response code to the controller 120. to provide.

In this case, the control unit 120 in the wireless meter reading unit 102 analyzes the response code received in step 312 of FIG. 4 and provides the valve closing or ring opening control signal to the valve driving unit 118 in steps 314 to 320 of FIG. The valve 115 is opened and closed, and as a result, a message is transmitted to the control server 110 through the CDMA modulator 124 and the RF module 126. For example, when the valve close message is received, the controller 120 outputs a valve close drive signal to the valve driver 118 to close the valve 115, monitors the state, and transmits a message to the control server 110 that the valve 115 is closed, thereby causing an abnormality. Monitor remotely that the valve of the finished water pipe is closed. For this operation, valve 115 must be coupled with a sensor that detects the open / closed state of the valve.

If it is determined in step 306 that no abnormal condition occurs, the controller 120 reads the output of the CDMA demodulator 124 in step 322 and searches whether RF data is received from the repeater 104. Here, the data received from the repeater 104 is data transmitted from the control server 110, and is a message such as a meter reading request, a confirmation signal (a confirmation signal that the meter data has been received), a valve control signal, and the like.

If it is determined in step 322 that the RF data has been received, the control unit 120 searches in step 324 whether the received data is a meter reading request message. If it is determined in step 324 that the meter request message, the control unit 120 reads the metering data stored in the memory 128 in step 326, and converts to the RF-CDMA data format in step 428, the repeater 104 through the CDMA modulator 124, RF module 126 To send.

The repeater 104 transmits the data received as described above to the mobile communication switch 106, the mobile communication switch 106 transmits the meter reading data received through the TCP / IP to the control server 110. The control server 110 updates the received meter reading data in the database and transmits a confirmation signal to the corresponding wireless meter reading unit 102. The confirmation signal output from the control server 110 is transmitted to the wireless meter reading unit 102 through the Internet 108, mobile communication switch 106, the repeater 104.

In this case, the control unit 120 in the wireless meter reading unit 102 determines that the confirmation signal has been received in step 330 of FIG. 4, and resets the metering data stored in the memory 128 in step 332. Here, the reset may mean setting the meter reading data to an initial state and marking the time information transmitted by the meter reading data to the control server 110 so that the new meter reading data accumulated later is transmitted.

On the other hand, when the control server 110 receives the metering data from one wireless metering unit 102, the wireless meter reading data transmitted from the wireless metering unit 102 and the neighboring wireless metering unit 102i and the average consumption of the water supply block 18 is compared and calculated As described above, the leak state of the corresponding water pipe is detected, and if it is determined that the leak occurs, the valve driving signal is selectively output. For example, when it is determined that the leak state, the control server 110 outputs a message indicating the position of the water supply pipe 113 where the leak occurred to the water supply terminal 112. The valve driving signal is input to the controller 120 through the RF module 126 and the CDMA transformer 124 as described above.

In this case, the controller 120 determines that the message received in step 324 is not a meter reading request message, and searches whether the valve close / open sound driving signal is performed in step 334. If it is determined that the signal received in step 334 is the valve closing drive signal, the control unit 120 outputs the valve closing drive signal to the valve driving unit 118 to close the valve located in the water supply pipe 113 to block the flow of the flow rate in the water supply pipe. Do not occur.

When the repair / replacement of the water pipe which leaks by the manager is completed and the repair completion message is transmitted from the waterworks terminal 112 to the control server 110, the control server 110 transmits a valve opening control signal to the corresponding wireless meter reading unit 102. The controller 120 in the wireless meter reading unit 102 outputs the valve opening driving signal to the valve driving unit 118 in step 338 of FIG. 4 to open the valve of the corresponding water pipe 112 and transmits the result message to the control server 110.

Therefore, the water leakage blocking and water flow rate wireless meter reading system and its control method according to the present invention by comparing the average consumption flow rate of the flow meter installed in the water pipe, that is, the meter reading data of the wireless meter reading and the water supply block connected to the corresponding water pipes It can automatically detect leaks and automatically open and close the valve located near the wireless meter of the water supply pipe in the remote control server 110 so that the leak can be repaired quickly, preventing waste of water resources. have.

As described above, the present invention can automatically detect leaks from water pipes at a remote location, quickly replace and repair leaks, and at the same time, wireless meter reading of a flowmeter can be used to more efficiently manage water resources. There is this.
