{INTELLIGENT WATER GAUGE SYSTEM CAPAPLE OF CHECKING MULTIPLE FUNCTION}

The present invention relates to an intelligent water meter multidermeter meter reading system, and more particularly, to an intelligent water meter multidermeter meter reading system that can easily break an inflow pipe and detect a leak.

The water meter comprises a flow rate detector for driving the impeller and a flow rate indicator for indicating the flow rate as a numerical value in accordance with a pulse provided by the flow rate detector. The flow rate detector further comprises an outer casing, an impeller assembly, And the outer casing is constituted as a coupler at both ends to be mounted on the water pipe and constituted as an inlet for inserting the impeller assembly into the inside of the casing and a flow path for the tap water. The impeller assembly is inserted into the casing, And a magnet attached to the impeller to form a magnetic field on the upper portion of the flow path cover. The flow path cover is formed by sealing the inlet of the outer casing containing the impeller assembly so that water does not leak, , And the flow rate display unit One is mounted on the top and in response to the polarity change of the magnetic field configuration as puzzles for integrating boards are interlocked to the gear assembly and the gear assembly is driven.

Constant supplied from the water source is transferred to the corresponding region through a constant diameter pipe having a large diameter (referred to as a main pipe). In these areas, the main pipe to each generation is supplied through the water supply pipe. In fact, there is no connection from the main pipe to each generation directly through the water pipe, and several water pipes having a middle diameter are connected between the main pipe and the water pipe, which are connected to the respective generations through the respective pipes . In each household, a water meter is installed at the end of the water pipe to measure the amount of water used by that household.

In general, however, it is not easy for the checkers to check the flow rate because private homes are buried in the ground and apartment houses such as apartments are buried in the walls. In addition, currently installed water meters are used only for measuring the amount of water used for each household.

3 is an explanatory view for explaining the installation structure of the water meter 50 and the multi-item detection control device 30 according to the embodiment of the present invention. The water meter 50 installed in each household is installed between a water supply pipe 20 into which a constant water flows and an outflow pipe 41 which supplies a constant water to each household. In the water supply pipe 20, two strands of sensing wires 21a and 21b are provided and it is possible to easily detect whether the water supply pipe 20 is damaged or not. The water meter 50 is provided with a protective case 53 for protecting against an external impact and a backflow prevention valve 51 for preventing reverse flow of the water from the outflow pipe 41. A pressure sensor 59 And a water leakage sensor 57 is attached to the inner surface of the water meter 50 to sense whether the water meter 50 is leaked or not. Further, the water meter 55 can be provided to measure the amount of use. The sensor wires 21a and 21b, the pressure sensor 59, the water leakage sensor 57 and the flow rate detection sensor 55 are connected to the breakage sensor cable 20a, the pressure sensor cable 59a, the leak sensor cable 57a, And is connected to the multi-item detection control device 30 using the sensor cable 55a.

FIG. 4 is a flowchart illustrating a process of installing and operating the intelligent water meter multi-item meter reading system according to the present invention. First, the initial resistivity value of the sensing line installed in the water supply pipe connected to each tap water meter is measured (ST 410). The initial resistivity value is stored in the multi-item detection control device to be installed in the water meter (ST 420). At this time, the initial resistivity value may be stored in the data logger unit of the multi-item detection control device or may be additionally provided with a separate memory and stored in a small-sized memory normally provided in the central processing unit. A multi-item measuring and controlling device is installed in each water meter by connecting a breakage sensor cable, a leak sensor cable, a hydraulic sensor cable, and a pressure sensor cable provided in each water meter to a multi-item detection control device (ST 430). When the next multi-item detection control device is driven, an internal timer built in the central processing unit starts operation (ST 440). When an event occurs at the time set in the internal timer, the flow rate / hydraulic pressure / leak measurement unit and breakage measurement unit are sequentially connected by the selection signal of the signal channel selection unit in accordance with the event to sequentially calculate the flow rate value, the hydraulic pressure value, The value is measured (ST 450). Then, the flow rate value, the oil pressure value, the leakage sensor value, and the resistivity value measured at ST 450 are stored in the data logger (ST 460). Next, it is checked whether a measurement data request signal is inputted from the mobile communication terminal 70 through the gateway device 40 (ST 470). If there is a data request according to the check result of ST 470, the measured flow value, the oil pressure value, the leakage sensor value, and the resistivity value are RF transmitted using the RF transceiver (ST 480). It is checked whether there is a data request according to the check result of ST 470 or a command for terminating the multi-item detection control device is inputted after ST 480 (ST 490). If the end command is inputted, If the termination command is not inputted, proceed from ST 450 again.

On the other hand, an application program called an app program for controlling the multi-item detection control device 30 is installed in the mobile communication terminal 70. 5 is a flowchart illustrating a state monitoring application program process flow in a mobile communication terminal. The meter reading source for monitoring the multi-item detection control device installed in each water meter is monitored while carrying the mobile communication terminal 70 and the gateway device 40 by using the ordinary vehicle (52 in FIG. 2). Of course, in the case of an apartment complex such as an apartment building, the metering staff visits the household or the office without going to the office or visiting the office, while monitoring the terminal while carrying the mobile communication terminal 70 and the gateway device 40. After the gateway device 70 is operated, the meter probe executes a status monitoring app program installed in the mobile communication terminal 70 to check the communication status with the gateway device (ST510). If the communication status between the status monitoring application program and the gateway device is normal, the meter probe moves to the vicinity of the water meter in the monitoring area (ST 520). The multi-item detection control device requests measurement data and waits for data reception (ST 530). The flow rate value, the oil pressure value, the leakage sensor value, and the resistivity value are displayed on the screen (ST 550). When the user requests the measurement value to be sent to the central sensing device 60 (ST 560), the measured flow value, the hydraulic pressure value, the leakage sensor value, and the specific resistance value are transmitted to the central sensing device 60 (ST 570) It is checked whether or not it is terminated (ST 580).

If it is determined in ST 540 that there is no data reception or ST 560 does not request data transmission to the central sensing unit 60 (ST 580), it is checked whether the data transmission is terminated (ST 580) If not, repeat from ST 530.

It is preferable that the initial resistivity value stored by step ST 420 of FIG. 4 is transmitted to the app program together with the flow rate value, the hydraulic pressure value, the leakage sensor value and the resistivity value measured according to the measurement data request of ST 530 in FIG. 5 Do. The application program can confirm whether or not breakage has occurred in the buried pipe by comparing the initial resistivity value with the measured flow rate value, the hydraulic pressure value, the leakage sensor value and the resistivity value stored in the data logger unit of the multi-item detection control device .
