The present invention relates to a system and a method for providing a location information through a coordinate value and a method for providing a location information using a RFID-embedded RFID tag and a portable terminal equipped with an RFID-reader. And recording the Jeonju localization number assigned to the power facility on the RFID-tag, attaching to the facility, and reading the position through the portable terminal equipped with the RFID-reader. In addition, by attaching the RFID ID tag, which stores the location information of the system such as the electric field mapping number, such as electric power facilities, not only power facilities, but also obtains accurate location information regardless of time and place. .

Currently, commercially available system for recognizing the location is using GPS signal and base station propagation.

The Global Positioning System (GPS), which uses the GPS signal, was developed by the US Department of Defense for its military purposes. It is an artificial satellite that enables the measurement of position, velocity, and time in a standard coordinate system regardless of climate anywhere on the planet. Advanced navigation system used. The navigation system GPS using the satellite is composed of a satellite group, and a ground control group and a user group for monitoring and controlling the satellite. The satellite group, which is composed of 24 satellites, is provided such that at least four satellites are always visible throughout the earth. It contains a precise and expensive atomic clock that travels around the earth with a period of time and has accurate visual information. The ground control group monitors and controls each satellite on the ground to keep it out of its orbit. The user group is composed of various devices including a GPS receiver for receiving the GPS satellite signal, extracting navigation data, and calculating a position and time.

The GPS receives a navigation message sent from the satellite and calculates a position at a receiver to determine a current position. The GPS measuring method includes an absolute positioning method and a relative positioning method. The absolute position measuring method is a position measuring method that indicates the position of the earth by analyzing the radio waves and codes of the satellites with one GPS receiver, and requires relatively low positional accuracy such as positioning, climbing, and sea position of high-speed moving objects such as automobiles and aircrafts. It is used in case of. On the other hand, the relative position measuring method is to obtain a position from a point from which the position is known to a point to know the position by installing a receiver at a known point, and the receiver of the unknown point and the receiver of the known point It is commonly used to calculate the position by measuring the phase of the carrier wave or the code to measure the difference in propagation time.

Currently, the application field using GPS is broadly divided into the ground transportation field, the marine transportation field, the air transportation field, the military field, the science / space field, the road transportation field, and the like.

However, since GPS needs to receive satellite signals, its cost is relatively high, and the location error reaches 3 to 10m, and the altitude error is higher than the location error, especially under crowded areas or under elevated roads. There is a problem that the signal is weak and does not properly recognize the location and can not be used in buildings, tunnels, underground, etc.

The use of the base station radio waves is developed in various forms and is being commercialized and serviced in some ways. Receiving a signal from neighboring base stations to determine the location of the portable terminal has the advantage that the existing portable terminal can be serviced without a separate transceiver. As a result, the accuracy of the error range is significantly lower than 500 m. In addition, there is a problem of incompatibility because a separate method is used for each service provider.

In addition, LBS (Location Based Service) using a dedicated wireless communication network is expected to be provided in earnest from July 2007, but this system is also used as a wireless method. There is an error of 20-30m in the accuracy of the opening and the sub-center within the accuracy, and does not display the altitude information.

In addition, the method using the GPS satellite signal or the base station propagation has a problem that the position value is different depending on the surrounding environment and time even in the same place.

As an alternative to solve the above problems, a patent and an electronic map retrieval apparatus (application number 10-2002-66225) using a Jeonju intellectualization number have been disclosed.

And map information output means for outputting, as map information, the digitized number of the telephone pole converted in the coordinate conversion means for converting the coordinates based on the data stored in the means.

Such conventional technology uses a number of Jeonju intellectualization numbers installed anywhere in the country, and does not use expensive GPS when searching for a current position and a desired position with a number system converted based on a flat rectangular coordinate. There is an advantage that you can easily search for geographic information using only Jeonju intellectualization number, but because the Jeonju intellectualization number is indicated on Jeonju Number Stamp attached to Jeonju, the user needs to use Jeonju Intellectualization Number directly. Checking the number plate, there is a hassle that you need to enter the telephone number of the telephone number indicated on the number plate in the text mode, or directly input through an input means such as a mouse or a touch pad, there is a problem in practical use.

In addition, since only the Jeonju intellectualization number is used, it is possible to locate only the Jeonju, but there is a problem that cannot locate the surrounding structures.In the case of the city center, the minimum unit is 50 square meters, and other areas are 100 square meters. Therefore, there is a problem that a large actual error occurs.

This numbering system also has a problem of not displaying altitude information.

In the present invention, in order to solve the above problems, the present invention provides a location guide system and a method thereof, and can read the intellectualization information from the RFID ID tag and the RFID ID tag installed with the intellectualization information recorded therein. It is an object of the present invention to provide a system and method for providing location information without using expensive GPS or base station radio waves through a portable terminal equipped with an RFID-reader.

It provides a system and method that can be applied to general structures as well as power facilities to provide relatively inexpensive system construction and services, and provides a system and method that is easy to use because users do not need to directly input intellectualization information. It aims to do it.

In addition, the error level is less than 1m by including a flat rectangular coordinate (TM) value and altitude information for error correction and 3D position recognition of the digitized number. An object of the present invention is to provide a system and a method capable of providing location information including floor information.

Hereinafter, with reference to the accompanying drawings will be described in detail a position guide system and a method using a portable terminal equipped with RFID ID tag and RF ID reader embedded with the present invention identification number information.

FIG. 1 is a diagram illustrating a configuration of a location guide system using a portable terminal equipped with an RFID-tag and an RFID-reader in which the present invention intellectualization information is embedded. As shown in FIG. 1, the system according to the present invention includes an RFID-tag 10, a portable terminal 20 equipped with an RFID-reader, a communication network 30, and a location information providing server 40. .

The RFID-tag 10 stands for Radio Frequency Identification-Tag so that predetermined information can be embedded in a microchip and tracked with a radio frequency. The tag is called an electronic tag or a start tag, an electronic label, or a radio identification. will be.

Therefore, the RFID-tag 10 is composed of a transponder chip and an antenna made of a semiconductor. There are passive and active types according to a power supply method. Passive type is operated by receiving energy from RF ID-reader's radio signal without internal power supply, and active type is built-in battery to operate by itself.

The RFID tag 10 is used at a short distance of 1.8 m or less of a low frequency radio frequency identification system (30 kHz to 500 kHz), and is 27 m or more of a high frequency system (850 MHz to 950 MHz or 2.4 GHz to 2.5 GHz). It can be used from a long distance.

The RFID-tag 10 according to the present invention is characterized in that the embedded information is intellectualization information.

The intellectualization information recorded in the RFID-tag 10 is information that may indicate a location in which the RFID-tag 10 is installed, and includes information matching with the planar rectangular coordinates in various number systems.

Among the various numbering systems used for such intellectualization information, the present invention is characterized by using the numbering system assigned to the telephone pole.

As shown in the figure for explaining the system of Jeonju localization number assigned to Jeonju, FIG. 2 is divided into urban and other regions, and is composed of 8 digits. The system of 8-digit Jeonju Intellectualization Number is divided into 2/2/1/1/1/1 digits from the front, and the management zone X coordinate / management zone Y coordinate / management zone type / X block / Y block / sequence It consists of.

As shown in the drawing illustrating the system of Jeonju Intelligent Numbers given to Jeonju as an example of an urban area, two digits from the front represent the X coordinate of the management zone and the unit is 2km. The next two digits represent the Y coordinate of the management zone and the unit is 2km. Therefore, the area of one management zone is 4 km ² . Thereafter, one digit divides the management zone and adds one digit name to it. In the case of urban areas, 16 divided sections are divided at 500m intervals, and other regions are divided into four divided sections at 1km intervals. One digit is the X coordinate of the block obtained by dividing the divided section by 100, and one digit is the Y coordinate of the block.

Thus, a block in an urban area becomes a square with 50m on one side and a square with 100m on one side.

After that, the last one digit is given according to the order of poles existing in the block and is independent of coordinates.

Therefore, when the intellectualization number of the urban area of FIG. 2 is '9715F592', it means '59' block of 2,500 square meters of 'F' divided area of 0.25 square kilometers in the '9715' administrative area of 4 square kilometers. . Therefore, the whole country is divided into blocks of 2,500 square meters in the urban area and 10,000 square meters of blocks in the rest of the country, and thus the Jeonju localization number is matched with the planar rectangular coordinates of latitude and longitude.

In the case of the block according to the designation number, the city center is 2,500 square meters and the other regions are 10,000 square meters, so that an error occurs in the block.

Therefore, the present invention is to store the TM coordinate value separately in order to correct the position error in the block when using the above-mentioned pre-intellectualized numbering system as the intellectualization information. Accordingly, the user can select and use the position coordinate or the plane rectangular coordinate value of the pole number system.

In addition, the intellectualization information according to the present invention further includes the elevation information. This coordinate provides the elevation information of the nationwide unified system based on Korea's level origin. Therefore, it is possible to provide vertical position information even in a building or basement with the same planar rectangular coordinate value, as well as knowing whether it is flooded in the event of an accurate altitude check, which can be helpful in establishing a flood protection plan. .

Accordingly, the portable terminal 20 equipped with the RFID-reader has a built-in program that calculates coordinates by calculating coordinates based on the intellectualization information received from the RFID-tag 10. Here, the calculation method and principle for calculating the coordinate value of the planar rectangular coordinate through the cadastralization information are well known and will not be described.

In addition, since the portable terminal 20 includes graphic information of a map in an internal storage space, the portable terminal 20 provides a graphic value instead of displaying a coordinate value corresponding to the cadastralized information read by the RFID-reader as a graphic. It features.

In addition, even when receiving the coordinate value of the other party from the other party through the communication network 30 is characterized in that it provides a graphic of the location of the other party rather than providing the location of the other party as a simple numerical value.

This is provided by loading the graphic information of the map in the storage space by the range set by the output means of the portable terminal 20 based on the coordinate value.

If there is no graphic information of the map corresponding to the coordinate value, the coordinate value is transmitted to the location information providing server 40 through the communication network 30, and the graphic of the map from the location information providing server 40 is transmitted. It is desirable to download the information.

In addition, the portable terminal 20 provides a graphic user interface (GUI), which is an input window for inputting a keyword for a search such as an address search, a name search, a neighbor search, and so on, so that a user can search for a desired location with a keyword. do.

At this time, the location search through the keyword input through the graphical user interface to search the information stored in the internal storage space, or transfer the keyword to the location information providing server 40 through the communication network 30 to search the corresponding location Result information can be received.

In addition, the portable terminal 20 is characterized in that the automatic transmission of the coordinate value corresponding to the intellectualization information read to the RFID-reader immediately before the transmission of the emergency call number, such as 112 or 119.

That is, in the case of an emergency call number, it is important to know the location of the caller. Therefore, the calculated coordinate value is automatically transmitted when the counterpart number and the number set as the emergency call number are sent.

At this time, the authenticity of the calculated coordinate value is determined by providing the counterpart with time information, etc., when the ID information is received from the RFID-reader.

The communication network 30 is a communication network of a general mobile communication provider, and is not limited to any specific communication network, and is a variety of networks capable of transmitting and receiving data by connecting to a portable terminal 20 equipped with an RFID-reader.
