Description

Method of displaying and making a memo for specific positions using GPS}

The present invention relates to a method of registering and storing a memo for a specific location using a GPS system and displaying proximity information for the location.

As is well known, the current satellite positioning system (GPS system) is an automatic navigation support system that has been developed since the early 1970s, and is a C / A (Clear) provided by GPS satellites. And Acquisition (24) can be used for all-weather positioning 24 hours a day, anywhere in the world, and the error range is about 100m.

The GPS system was first developed for military purposes, but now part of the GPS signal is used by the general public, thereby making it easy to use location tracking.

The GPS satellites consist of 24 satellites orbiting six orbital planes separated by 60 degrees with a 55 degree orbital inclination, so that theoretically, four or more GPS satellites can be observed anywhere on the earth.

Basically, the method of securing the position coordinate value by using the GPS system determines the position by observing the distance from the satellite to the GPS terminal using a triangulation principle based on the satellite. That is, the distance measurement between the GPS satellites and the GPS terminal can be obtained by multiplying the speed of the light from the GPS satellite to the time it takes to receive the signal from the GPS terminal, wherein the time from which the signal is transmitted from the GPS satellite and the GPS terminal The exact time difference received at For this purpose, an atomic clock with extreme precision is built into the GPS satellites using vibrations of specific atoms, and the GPS terminal adopts a clock with appropriate accuracy instead of an expensive atomic clock. In order to maintain the synchronization with the time error correction method is used.

Meanwhile, in order to display a geographic location on a display window on a GPS terminal, predetermined map data is decoded and displayed as a visual map. There are two methods for storing such map data. One method is to store map data in a Geographic Information System (GIS) server that stores and outputs map data to be transmitted to a GPS terminal. The other is to store map data by placing a predetermined map data storage unit in the GPS terminal itself. . As a result, the GPS terminal receives a map for a specific location from the GIS server or a map data storage unit in the terminal itself and displays it on the GPS terminal display window, and also provides various services such as proximity information about the specific location selected from the current location. To provide.

However, as described above, in order to receive a variety of services such as proximity information by selecting a specific location on the displayed map, the user must first designate a specific location on the map. However, since such maps are data that is already definitely stored in the map data storage unit in the GIS server or the terminal, the area name displayed on the map is definite. Therefore, in order to find the location again later, it is inconvenient to remember the exact geographical location or to remember the exact location name for the location.

Therefore, the present invention has been proposed to solve the above problems, the user can store his own specific location GPS location information in a separate space with a predetermined memo to easily find the place using the stored information over time It aims to be able to visit. In addition, an object of the present invention is to increase the convenience of location tracking by displaying proximity information along with a memo on the display window of the GPS terminal.

In order to achieve the above object, the present invention, by using a global positioning system (GPS, Global Positioning System) to store the location that the user wants to remember with the memo, it is possible to easily find the same place in the future and It provides a method of displaying proximity information on a display window on a GPS terminal. To this end, the GPS terminal designates a specific location from the GPS terminal user and registers a memo for the corresponding location, and registers a memo for the corresponding location, and displays a list of memos of each specific location registered by the GPS terminal user. And selecting a memo of a specific location, and displaying the proximity corresponding to the selected memo, and displaying proximity information of the corresponding map and the corresponding location on a display window of the GPS terminal.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing a circuit configuration of a GPS terminal according to an embodiment of the present invention.

Referring to this, the GPS receiver 110 receives a location information code transmitted from a GPS satellite through an antenna, and the key input unit 120 uses a direction key to designate a specific location to be displayed on a display window on a map on the screen. A designated key and a map zoom key. The user can specify a specific location on the map in detail by using these direction keys, designation keys, and zoom keys. Key usage will be described in detail in the location designation and memo registration step S210 of FIG. 2.

The screen display unit 150 outputs a combination of the location information received through the GPS satellites and the electronic map of the Geographic Information System (GIS) server or the map data storage unit in the terminal through a display window. The GIS server stores and outputs map data to be transmitted to the GPS terminal. The GPS terminal decodes the map data received from the server and displays a map of a specific location on the display window. If a space for storing map data is set aside in the GPS terminal, location information received from a GPS satellite in the terminal itself is displayed as a map on the display window without receiving the map data from the GIS server.

The map data storage unit 130 is a place where map information of a predetermined region corresponding to the location information received through the GPS satellites is stored as data. The GPS terminal displays the map information on the display window, thereby allowing the terminal user to easily specify a specific location. If there is no such electronic map data storage unit, the GPS terminal can display a map for a specific location by receiving map data from the GIS server.

The location memo storage unit 140 is a place where memo contents input by a user for a specific location selected from a map on the screen are stored. When the memo is saved, the memo stored in the location memo storage unit is displayed with the map when the corresponding location is displayed again. For example, when a user selects a specific location on the map and enters 'Hong Gil-Dong Office', the memo 'Hong Gil-Dong Office' is stored with the location in the location memo storage to find the 'Hong-Kil-Dong Office' later. As shown in the note, along with a map of the location, memo content, location proximity information, etc. are displayed.

The location proximity calculator 160 performs a function of analyzing specific location proximity information such as a distance, a direction, and a moving time estimate between a location of a current GPS terminal and a location specified on a map and provides the same to a user. This analysis method is the same as the existing GPS location tracking analysis method and is not related to the gist of the present invention, a detailed description thereof will be omitted.

The controller 100 controls each of the above functional units and analyzes the location information applied through the GPS satellites to display the corresponding location map on the display window.

2 is a flowchart illustrating a process of memorizing a specific location using the GPS information and displaying location proximity information thereof.

First, the GPS terminal has a location designation and memo registration step of receiving a destination location designation and a memo for the corresponding location from the user (S210).

There are three methods for location designation. In the first method, when memo registration items are selected from memo registration, modification, deletion, and list items, the map data stored in the electronic map data storage unit is displayed. It is displayed on the screen display, and the user designates the position he or she wants to select using the zoom input / reduction key, direction key, and designation key. That is, after selecting the map of the city of Seoul that appears in the display window as shown in Figure 3, by using the direction key 340 of the key input unit to select the location on the map to specify. For example, if it is assumed that the building A of Gangnam Station located in Gangnam-gu as its destination, the user places the arrow 300 in Gangnam-gu using the direction keys 340 and then presses the zoom-in button 310 to determine the You can zoom in on the map in more detail. In this way, if the map of Gangnam-gu is enlarged, the location of a specific building of Gangnam Station can be found as shown in FIG. After finding the location of a specific building in Gangnam Station, the arrow 400 can be positioned on the building A, which is a corresponding building, by using a direction key, and then a designation can be made by pressing a designated button.

The second method is to enter the position of the destination directly by text. For example, when the user directly inputs the location of the destination as 'Gangnam Station', the GPS terminal displays a map around the Gangnam Station on the display window. When the map near the Gangnam station is displayed, the user can specify the building he wants to find. Geographic location by character recognition of the area name searches for the area name stored in the electronic map data, finds a geographic location matching the same, and displays the map.

The third method is to display the region names in the electronic map data storage in a list window. The user can select a region name corresponding to the location he wants to find from the displayed list. Therefore, when the 'Gangnam Station' is selected from the list of local names, a map near Gangnam Station is displayed, and the user can find and locate the building he wants to find on this map.

When the position designation is completed as described above, the GPS terminal displays a memo input column for the corresponding position on the display window. The user can enter his own note for the location. For example, as shown in Figure 4, if you select the location of the building by pressing the Assign button after placing the arrow in the building A, a note input window for the building appears, the user can recognize yourself like 'Hong Gil-dong office' You can enter the memo. In this way, the memo is stored in the location memo storage unit 140 of FIG. 1 together with the location of the corresponding building. As shown in FIG. 5, the memo may be modified, deleted, or displayed in a list using a memo edit menu item on a display window.

After going through the location designation and memo registration step as described above, the user selects the memo list item shown in FIG. Through this, you can easily find the location. For example, when the memory list display item is selected as shown in FIG. 5, the terminal displays a memo list registered so far as shown in FIG. 6. When one of the list items is displayed, the GPS terminal determines the location on the map that matches the selected memo (S230). After the location is determined, the location proximity calculation unit of FIG. 1 calculates the proximity information such as the distance between the location and the current location, direction, and estimated time required, and displays it on the display window together with the corresponding map and the corresponding memo ( S240).

For example, when the user selects 'Hong Gil-dong office' in FIG. 6 displaying a memo list, the GPS terminal displays a location map matching the selected memo on the display window, and further, the distance between the current location and the Hong Gil-dong office and the current location. It displays proximity information about the destination such as Hong Gil-dong office direction and estimated time to move the vehicle. Accordingly, unlike the uniform map when registering a memo for a specific location in FIG. 4, the memo content 710 and the proximity information 720 are displayed together on the map, so that the GPS terminal itself is displayed. You can display a map for a specific location so that users can easily identify it.

Although the technical spirit of the present invention has been described in detail according to the above-described preferred embodiment, the above-described embodiment is for the purpose of description, and various ordinary embodiments of the present invention may be made by those skilled in the art. I can understand.

As described above, by registering and storing a memo for a specific location using GPS and selecting a registered memo to find a specific location, the user can easily find the same place in the future without remembering the exact location. . In addition, by displaying the proximity information on the location with the memo on the map, there is an effect that can conveniently use the location tracking service using GPS.
