Water meter reading system using WPS {REMOTE WATER METERING SYSTEM USING GPS}

The present invention relates to a water meter reading system using GPS, and more particularly, a digital water meter is installed in each home, and the water consumption measured by the digital water meter is received by the PDA terminal via RF transmission, but using GPS. GPS readers can easily read the bed-bed building at a long distance from a PDA terminal, and can also read the water consumption of each home or building at a long distance, thereby greatly improving the efficiency and convenience of meter reading work. It relates to a water meter reading system using.

In general, each home or building is equipped with a water meter for measuring the amount of water used, and the water meter is embedded in the ground so that the water pipes are buried in the ground so that the water pipes are buried in the ground, and are installed in the pipes that pass through the water tanks. In order to protect the meter, the meter guard is opened and closed by a cover.

Therefore, the water meter reader reads the water meter by opening the cover and checking the scale of the meter installed inside the meter protection container.

If the above water meter is installed outdoors, the meter reader can easily read the water meter regardless of whether or not there is a person in each home or shopping mall. In other words, since it is installed indoors, it is impossible to read the water meter when there are no people in each home or mall, and the meter reader has to visit several times. It takes a lot of time, so many meter readers are required, which also costs a lot of meter reading.

In order to solve such a problem, conventionally, a water meter automatic meter reading system has been proposed to install a camera in the water meter and allow the meter reader to read the water consumption outdoors.

However, the metering system as described above has a problem in that the quality of the image taken by the camera is deteriorated due to moisture inside the protective case when the protective case containing the camera is incompletely sealed and used for a long time. In the process of checking the meter, there was a disadvantage in that the protective case was broken and the photographed image (reading value) could not be recognized.

Looking at the prior art, a water meter remote meter reading system using a mobile communication network, registered utility model No. 20-0413730 has been devised, as described in the claims of the published notification, which reads the number displayed on the instrument panel of the meter A system, comprising: reading and storing data obtained by converting meter reading data into set data at a predetermined time and a unique ID value of a meter and transmitting the same to a mobile communication company; and receiving and storing data transmitted through the meter reading means, A central processing server for transmitting the meter reading data and the unique ID value of the meter to the water management office, storing the meter reading data and the unique ID value of the meter, and storing the unique ID value of the registered meter and Calculate the amount of usage of the meter by comparing the unique ID value of the transmitted meter It consists of an exit server.

However, such a remote metering system has an excessive cost such as replacement of a conventional water meter and installation of a repeater, and also a few meters that are not easy to communicate due to a long distance from a communication repeater in transmitting meter readings remotely. If this is the case, it is difficult to add a separate repeater for this purpose, but there is a problem that this method is inefficient even if the meter is too dense or too wide.

As another example, an automatic wireless meter reading system of a water meter with a patent registration number 10-0829350 has been devised, which is a digital meter or contact type water meter and the water meter in an automatic wireless meter reading system of the water meter A meter connected with a common cable, a communication repeater connected to the meter and a wireless network, a communication repeater collecting a meter reading received from the water meter at a long distance, a communication repeater connected to the communication repeater and a wireless network, and a meter reading from the meter. And a wireless concentrator that collects meter readings for each meter and collects meter readings received from the water meter at a short distance, and responds to it within a few seconds when inquiring. The concentrator and the holiday via a public telecommunication network. Collecting the meter reading value is sent from the radio equipment, and is configured by it as the control server for managing access according to the amount of the water meter.

As another example, a remote meter reading system and a method using the WPS of the Patent Publication No. 10-2004-0009448 has been devised, which is to determine the position of the metering target device using a GPS remotely, and In a remote meter reading system for reading the device on the bed by communicating wirelessly, using the GPS to display the location and the location of the device to be read with geographic information, if the device to be approached within a certain distance And a remote meter for automatically communicating with the metering target device to receive metering data from the metering target device, and connected to the remote meter in a wired manner to receive and store the metering data from the remote meter. Based on this, the meter reading and remote meter reading center used for statistical analysis It is configured for reading information about the target device as the data by reading a database to store management.

However, this conventional technique is uncomfortable to move to near the target building or house that the meter is to be read, since the meter reading is carried out only when the meter carried by the reader is approached to the device to be read. In addition, there is a problem that the reading signal transmitted from the meter reading device due to the surrounding buildings or the environment is not properly transmitted to the remote meter reading side, resulting in inconvenience due to a drop in transmission rate.

In addition, since the meter reading value and the stored meter reading value are not displayed, the reader can not grasp the water consumption of the delivery or the metered water consumption, and thus it is not immediately presented at the request of the consumer, thereby greatly reducing the consumer's reliability. In other words, there is a problem that the reader has to visit the area to be read, since the building or house to be read is not displayed at all on the portable meter.

The present invention, which was devised to solve the problems of the conventional water meter reading system, by further configuring the GPS receiving module in the PDA terminal can easily identify the location of the building or house on the bed through the GPS satellite, Can be checked through the PDA directly, so that the current usage and transmission usage can be grasped, thereby increasing the consumer's reliability and preventing the reception rate from dropping by the RF (Radio Frequency) module transmission as well as the outdoor indicator installed outdoors. The purpose of the present invention is to provide a water meter reading system using GPS that improves the efficiency of the meter reading work by allowing the meter to be read while the meter is moved to the vehicle by the GPS and RF module transmission even if it is not located nearby.
