Description

Apparatus and method for displaying map data using terminal}

The present invention relates to a map data display apparatus using a terminal and a method thereof.

More specifically, to update the data information that is changed from time to time to provide the current location and movement route, various geographic information, traffic information, etc., to display the current location of the user and the exact location of the destination. A map data display apparatus using a terminal and a method thereof are provided.

A similar display method in the related art is a car navigation system (CNS). Current vehicle navigation system uses latitude, longitude, and altitude from a plurality of satellites belonging to the Global Position System (GPS) to check the current position and moving speed or to determine the movement route for various moving objects such as ships and aircrafts. After calculating the current position of the moving object by receiving a radio wave indicating the back, and displaying the map information including the current position to the driver. That is, the conventional navigation device displays the current position of the magnetic moving object calculated using the information received from the GPS on the map displayed on the display screen. In addition, it provides the driver with various information necessary for driving, such as displaying the moving direction of the moving object, the distance to the destination to be traveled, the current moving speed of the moving object, the route set before the driver and the optimum route to the destination. .

Despite this state-of-the-art vehicle navigation system, the navigation device does not actively cope with the current situation of the road. In other words, the road on which the vehicle runs frequently generates new roads due to numerous constructions and constructions, and the situation continues to change, such as the disappearance of existing roads or the closure of roads due to long-term construction. Since the CD is already a storage medium such as CD-ROM (Compact Disc Read Only Memory), the navigation device is useless for the road information of the constantly changing situation. This is because a CD-ROM is a read-only storage medium.

In addition, it is a big burden for the user to purchase a new CD-ROM storing the modified map. In addition, the system lacks universality, so that vehicles that are walking or using public transportation, and vehicles that are not equipped with vehicle navigation systems, cannot receive their current location and route, and cope with current road conditions such as traffic jams. I couldn't figure it out.

That is, all map data including the conventional vehicle navigation system cannot receive the information of the map data which is changed from time to time. In addition, since map data is not easy to change, information that changes frequently, such as traffic information, is not included in the data from the beginning.

Therefore, the map data is supplied to the end user through a certain period of time, such as a certain survey period and production period, so that the latest traffic information generated due to changes and congestion after the survey period is completed is supplied to the user despite the most important data. I can't. In addition, even if the user can not always purchase the latest data from the user's point of view, there is a problem in that the additional cost of the double-triple that must be purchased again. In addition, mobile terminal companies and telecommunication companies are preparing or commercializing a variety of services to enable the provision of information using maps. However, the mobile terminal companies and the telecommunication companies do not supplement the basic disadvantages as described above. Although only map data should always be supplied to the user with the latest data, it is still being supplied with incorrect data.

An object of the present invention is to update the data information that is changed from time to time to provide a current location and moving path and various geographic information and traffic information so as to solve the above-mentioned problems, the current own location and destination to proceed to any destination The present invention provides a map data display apparatus and a method using a terminal for displaying the exact location of the same.

A calculation unit 12 for calculating the number and converting the calculated leaf number map data into XY coordinate values, a sending unit 13 for sending the leaf number through the calculation processing unit 12, and forwarding from the server Receiving unit 14 for receiving the map data to be received, map data storage unit 15 for storing the read / write map data transmitted through the receiving unit 14, arithmetic processing unit 12 and map data storage A system controller 16 for controlling, transmitting or processing map data transmitted from the unit 15, a display unit 17 for displaying map data controlled, transmitted or processed through the system controller 16, and various use It is configured to include an operation section 18 for operating the related information.

That is, the GPS receiver 11 receives values such as longitude, latitude, altitude, and time through the GPS. The calculation processing unit 12 calculates and stores the drawing number so that the corresponding numerical map using the received longitude and latitude data can be used directly. At this time, the leaflet number is sent through the sending unit 13, and if the user does not specify any point, the leaflet number including the current location point is sent. In addition, since the user using the display unit 17 and the operation unit 18 can use the map, this series of tasks is transmitted to the system control unit 16.

Here, in order to supply the user with the latest map data, first, a terminal with embedded map data is released, and after the terminal is released, an index table for the changes or frequent changes based on the survey date is checked to check the changes. do.

Briefly describing a map data display apparatus using a terminal according to the present invention, receiving the received data from the GPS to determine the user's position by the longitude and latitude values. Subsequently, when a user searches for his / her location and a user needs a request, the corresponding map data is read out through the request analysis, and the data of the server is accessed (posting a leaf number) and compared with an index table prepared in advance. Thus, if there is no change, the read map data is immediately displayed through the display unit. If there is a change, the read map data is changed and displayed through the display unit.

Detailed description of the above items is the same as FIG. 2A and FIG. 2B.

2A and 2B are explanatory diagrams showing changes of map data according to the present invention in a table, and if there is a changed leaf number, a change of a matching leaf number is found after comparison with a requested leaf number.

Next, a change / add / delete data is read and sent with reference to the change history table (FIG. 2B). Here, the leaf number is given to pieces (see Fig. 6) for ease of map data retrieval (however, in the case of numbering, the numbers calculated based on the values of longitude and latitude are combined and pasted).

In addition, the process of the terminal during the series of processes as described above will be described as shown in FIG. If there is changed data, data such as road, background, traffic information / property are classified, and each received data is changed, added, deleted, adopted or avoided through a series of processes.

Here, the adoption and avoidance is a matter that is changed in real time according to the traffic information, and is a method for notifying the congestion of the road. Therefore, relatively fast roads are guided in the path calculation (speed ← HIGH), and slow roads are avoided in the path calculation (speed ← LOW).

5 is a flowchart illustrating a method of displaying map data using a terminal according to the present invention.

As illustrated in FIG. 5, a map is displayed on a terminal after a user requests a geographic information service. At this time, if there is updated data in the area of the requested map, the latest map data through automatic upgrade is displayed on the terminal.

First, it is checked whether the user requests the geographic information service (S501).

As a result of confirming the above-described step (S501), if the geographic information service is requested, values such as longitude, latitude, altitude, time, etc. are received through the GPS receiver (S502) to calculate and extract the current location of the self (S503), and The leaflet number is extracted by calculating the leaflet (S504).

Subsequently, it is necessary to confirm whether there is updated data from the server before displaying the map data on the display unit, so that the leaf number obtained by the calculation is sent to the server (S505).

Thereafter, it is checked whether the leaf number sent from the server is the updated leaf number (S506).

As a result of confirming the above-mentioned step (S506), if the updated leaf number is inquired about the details of the update data, the change data is extracted (S507), and the extracted change data is sent (S508).

As a result of confirming the above-mentioned step S506, if it is not the updated leaf number, it is regarded that there is no updated data, and no change data is sent (S509).

Up to now, a series of processes for extracting whether the leaf number received from the server is an updated leaf number or, if so, which items have been updated and immediately sending them to the terminal, is described.

Subsequently, the map data is received and retrieved through the information receiver (S510), the map leaf of the corresponding area is read from the map data storage unit (S511), and it is checked whether there is changed data (S512).

As a result of checking in the above-described step (S512), if there is changed data, the data to be changed is updated in the map data of the read-out map (S513), and the updated data is transmitted to the system control unit (S514). It is displayed (S515).

On the other hand, if there is no changed data as a result of confirming the above-described step (S512), it is immediately transmitted to the system control unit (S514) to display the map data and the user location on the display unit (S515). The user's location is displayed on a map as a point or a picture in a separate display.
