On the other hand, in recent years, a remote metering method of remotely reading only the water consumption of the consumer through a communication repeater installed in the water meter has been partially applied. However, although the conventional remote metering method has an effect of increasing the convenience of meter reading, the excess flow of the water meter is analyzed by analyzing the reverse flow rate and the frequency of the flow rate at the customer, and comparing the water meter installed in the customer with the actual water consumption. It does not provide any device for analyzing undetected titration.

In addition, the conventional remote metering method is impossible to determine the poor water discharge due to the pressure change in the water pipe, the rupture of the pipe due to leakage, etc., excessive communication costs in the process of continuously transmitting the flow data to the server It occurs, and the load of the management server is increased as data is collected in real time from a plurality of meters in one management server.

In addition, the number of data transmissions in the process of continuously reading the flow rate data to the management server by the remote meter reading, and the number of attempts to connect to the communication network of the signal detector also increases the energy consumption of the signal detector to detect the flow rate from the flow sensor This caused a need to install a separate power line for supplying external AC power to the signal detector.

An object of the present invention is to provide a water meter remote metering system for solving problems such as missing meter reading, manual meter reading, difficulty in meter reading, operation of the meter, possible frequency, excessive metering costs and the like.

In addition, the present invention is to collect the data installed on the customer side in order to solve the disadvantage that occurs when the continuous flow of the flow data from the conventional signal detector to the management server, such as leak detection, usage adequacy analysis, etc. By analyzing and transmitting raw data from the signal detector and transmitting only the processed data to the management server, the management server minimizes the management cost by minimizing the load on the management server and consumes energy of the signal detector according to the remote meter reading. In order to reduce the communication cost by minimizing the amount of data transmitted to the management server and to detect the amount of water discharge due to the pressure change in the water pipe, it is to provide a water meter remote meter reading system.

In addition, the signal detector detects the number of reverse flows through the electronic sensor, and may correct and output the flow rate data based on the detected number of reverse flows.

Also, if the flow rate increases more than the preset level and the flow rate increases more than the preset level for more than the preset time based on the flow rate data, the data collection analysis and transmitter sends a leakage to the management server or the manager terminal through the communication network. You can notify.

In addition, the data collection analysis and transmission unit, based on the flow rate data, if the state of the flow rate is greater than the first value for more than the first preset time, or if the state of the flow rate is less than the second value for more than the preset second time, through the communication network The management server or the administrator terminal can notify the change of the diameter of the water meter.

According to the present invention, there is an effect of resolving problems such as omission of meter reading, difficulty in meter reading, manual operation, meter operation, frequency, and excessive metering cost through remote meter reading.

Hereinafter, a water meter remote meter reading system according to an embodiment of the present invention will be described with reference to the accompanying drawings.

1 is a block diagram showing a water meter remote meter reading system according to an embodiment of the present invention.

Referring to FIG. 1, the water meter remote meter reading system 100 includes a water meter 110, a signal detector 120, a pressure gauge and a pressure transducer 130, a data collection analysis and a transmitter 140, and the like. The components shown in FIG. 1 are not essential, so the water meter remote meter reading system 100 may be implemented to have more or fewer components.

The water meter 110 performs a function as a meter for reading water consumption. In addition, a rotary plate, which is a non-metallic conductor, is mounted on the needle connected to the flow section wheel for remote meter reading. Accordingly, the rotating plate moves in the same manner as the increase and decrease of the flow rate, and the movement of the rotating plate is used for obtaining the flow rate data in the signal detector 120 for the remote reading.

The signal detector 120 is integrally coupled to the water meter 110 and includes an electronic sensitive sensor. In addition, the flow rate data is detected by detecting the movement of the rotating plate using the electronic sensor. In addition, the detected flow rate data is transmitted to a data collection analysis and transmitter 140 which will be described later at predetermined intervals.

Here, in order to transfer the detected flow rate data to the data collection analysis and transmitter 140 at predetermined intervals, the signal detector 120 needs to include a memory (not shown) therein. That is, the signal detector 120 stores the flow rate data collected for a predetermined time in the internal memory, and transfers the flow rate data pre-stored in the internal memory to the data collection analysis and transmitter 140 when a predetermined period is reached.

In addition, the time point of data collection analysis and delivery to the transmitter 140 can be set by the management server 300. Accordingly, the management server 300 may change the time point at which the flow rate data is transmitted from the signal detector 120 to the data collection analysis and the transmitter 140 as necessary.

On the other hand, the electronic sensor of the signal detector 120 is configured using three magnetic coils, each number is given to each coil is not only rectified but also reverse flow detection is possible. Therefore, the signal detector 120 detects the number of backflows by using the electronic sensor and corrects the error according to the backflow in the flow rate data. As the reverse flow correction is possible through the signal detector 120, the meter reading value read by the water meter 110 coincides with the meter reading value according to the remote meter reading.

As described above, in the case of acquiring the flow rate data using the electromagnetic sensitive sensor, there is an advantage that not only the flow rate data error occurs due to the reverse flow but also is not affected by the external magnetic force. In addition, since the flow rate data is acquired without being affected by the meter shaking, there is an advantage of obtaining accurate data.

The pressure gauge and the pressure converter 130 perform a function of detecting a pressure change in the water pipe, and convert the pressure change detected through the pressure gauge inserted in the water pipe into pressure data using a pressure converter.

The data collection analysis and transmitter 140 is connected to the signal detector 120 and analyzes the flow rate data output from the signal detector 120. In addition, based on the analysis result, statistical information, such as water consumption and water usage patterns of the consumer, may be calculated.

In addition, the magnetic data collection analysis and transmitter 140 may analyze the flow rate data detected through the signal detector 120 to determine whether or not the leakage occurs. The data collection analysis and transmitter 140 continuously analyzes the flow rate data acquired through the signal detector 120 to increase the water usage by more than a predetermined level and to increase the usage by more than the predetermined level. Judging by the leak. For example, it may be determined that a leak occurs when a predetermined flow rate is continuously used for a predetermined period of time at a customer who has not used the amount between 24 and 7 o'clock.

In addition, the data collection analysis and transmitter 140 may calculate the amount of undetected usage outside the performance by analyzing the flow rate data detected through the signal detector 120.

In addition, the data collection analysis and transmitter 140 may determine the failure of the meter by analyzing the flow rate data detected through the signal detector 120.

In addition, the data collection analysis and transmission device 140 may analyze the flow rate data detected through the signal detector 120 to determine a suitable aperture suitable for the water consumption of the consumer. If the usage meter reading over the maximum flow rate that can be read by the current meter aperture lasts for a predetermined period or more, the data collection analysis and transmitter 140 determines that the meter aperture needs to be replaced by a larger aperture. On the other hand, when the meter reading below the minimum flow rate that can be read at the current meter aperture lasts for a predetermined time or more, the data collection analysis and transmitter 140 determines that the meter aperture needs to be replaced with a smaller aperture.

In addition, the data collection analysis and transmitter 140 analyzes the pressure data detected through the pressure gauge and the pressure transducer 130 to determine whether the pipe rupture. For example, if it is determined that the pressure in the water pipe has dropped sharply based on the pressure data, it may be determined that the water pipe ruptures.

In addition, the data collection analysis and the transmitter 140 may determine whether there is a water discharge failure by analyzing the pressure data detected through the pressure gauge and the pressure transducer 130. In general, the water pressure in the pipeline of the customer varies depending on the height of the zone. For example, in low-zone customers, the pressure in the pipeline is low, and in areas with relatively high or low density, the pressure in the pipeline is higher. Therefore, the pressure data of the water pipe can be used as a data for distributing the water pressure toward the lower side by lowering the pressure in the pipeline by installing a pressure reducing valve in the pipeline of the high pressure consumer.

On the other hand, the data collection analysis and the transmitter 140 through the analysis of the flow rate data collected through the signal detector 120, the above-described statistical information, leakage occurs, undetected usage outside the performance, meter failure, appropriate aperture information, Analysis data including at least one of whether a pipe rupture, poor water extraction, or frequency may be generated, and the generated analysis data may be transmitted to the management server 300 through the communication network 200. Here, the period or time point for transmitting the analysis data to the management server 300 can be controlled by the management server 300. Therefore, the management server 300 can receive the analysis data at the required time.

In addition, when the flow rate data is requested from the management server 300, the data collection analysis and transmitter 140 may transmit the flow rate data collected from the signal detector 120 to the management server 300 without processing.

In addition, when a request for changing the flow rate data collection cycle of the signal detector 120 is received, the timing at which the flow rate data is collected from the signal detector 120 may be controlled based on the request.

In addition, the data collection analysis and transmitter 140 may notify the management server 300 through the communication network 200, or transmit a message informing the manager terminal 400 of the leakage when it is determined that the leak occurs. .

In addition, when the data collection analysis and transmitter 140 determines that the meter diameter needs to be changed, requesting the meter diameter replacement to the management server 300 or the manager terminal 400 through the communication network 200 and guiding a suitable diameter. Information can be sent.

In addition, the data collection analysis and transmitter 140 detects the occurrence of backflow through the signal detector 120, and intentionally installs the water meter 110 upside down based on the period in which the backflow continuously occurs to generate a continuous backflow to increase the flow rate. You can determine whether you want to use it illegally. For example, if the backflow continues for more than a predetermined time, it can be determined that the water meter is intentionally installed upside down.

The communication network 200 includes a mobile communication network or a wired / wireless internet network, and includes a water meter remote meter reading system 100 and a management server 300, a water meter remote meter reading system 100, an administrator terminal 400, and a management server ( 300 to support communication between the manager terminal 400.

The management server 300 calculates a water rate of each customer using the analysis data collected through the data collection analysis and the transmitter 140, and continuously monitors the water usage of each customer.

In addition, as a result of monitoring the water consumption of each consumer, when it is determined that a leak has occurred, a message for guiding the leak may be transmitted to the manager terminal 400 through the communication network 200.

In addition, when the meter size replacement is necessary based on the data collection analysis and analysis data collected from the transmitter 140, a message for guiding the meter replacement and proper size information may be transmitted to the manager server 300 through the communication network 200. .

The manager terminal 400 is a terminal 400 of a manager who manages a member of each customer or water consumption of each customer, and is a terminal capable of transmitting and receiving data through the communication network 200.
