Abstract

PURPOSE:To obtain a GPS location recognizing apparatus which permits a current location to be known and an azimuth and a distance of a destination to be known. CONSTITUTION:A current position (location) can be recognized by utilizing a GPS device 1 for receiving electric waves from a GPS satellite to measure a current position and a location data storage part 4 for storing position information (latitude and longitude) and corresponding data of the location. A GPS location recognizing apparatus has a structure wherein a distance and an azimuth of a destination can be known by inputting a destination location by a location input part 5.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a GPS location recognition device having a function of confirming a location and displaying position information of a destination location.

[0002]

2. Description of the Related Art At present, it is known that the current position of oneself can be measured using GPS satellites and the position information (latitude, longitude, altitude) can be recognized.

[0003]

However, in the conventional GPS device, even if the latitude, longitude and altitude of the current position can be confirmed, the location indicating the location is not known and the location of the destination is known. There was a problem that the destination had to be searched on the map when the position was not clear.

The present invention solves such a problem, and an object of the present invention is to provide a GPS location recognition device capable of confirming the current location and the location of the destination.

[0005]

In order to achieve the above object, the present invention provides a GPS capable of confirming the present position.
The device, the position information display section that displays the position information (latitude, longitude, altitude) indicating the current position measured by the GPS device, and the data corresponding to the position information and the location are stored, and the position information is stored when necessary. The location data storage section that reads out the location based on the location and the location information that reads out the location information based on the location, the location name input section for entering the location of the destination, and the location entered in the location name input section are displayed. A location display unit that displays the location read out in the storage unit.

[0006]

With this configuration, the user can confirm the location of the current location, and if the location of the destination is known but the location is not clear, if the location data is input to the device, the destination can be confirmed. It works to display the latitude, longitude, altitude, and the distance and direction to the destination.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of the main part of a GPS location recognition apparatus according to an embodiment of the present invention.

In FIG. 1, reference numeral 1 denotes a GPS device that receives electric waves constantly sent from GPS satellites by an antenna 2 and indicates the current position, and 3 shows position information (latitude / longitude / altitude) measured by the GPS device 1. The position information display section 4 to display stores the data corresponding to the position information and the location, and reads the location based on the position information when necessary, and conversely reads the position information based on the location. Part 5 is a location name input section for entering the location name of the destination,
A location display unit 6 displays the location input in the location name input unit 5 and displays the location read out in the location data storage unit 4.

Next, the relationship and operation of each of the above components will be described (see FIG. 2). (1) When the user wants to know the location (whereabouts) of the user's current position, the user measures the position information of the current position using the GPS device 1. The position information is displayed on the position information display unit 3 and at the same time, the location corresponding to the feed position information is read out to the location data storage unit 4. Here, the location data storage unit 4 will be described with reference to FIG. Location information (latitude /
(Longitude) and location are, for example, north latitude XX degrees XX minutes XX seconds,
Location corresponding to east longitude ○○○ degree ○○ minute ○○ second is ○○ prefecture ▽
▽ City □□ Town ○ It has a relationship as if it were chome. In FIG. 3, the location A corresponds to the location information a, and the location B corresponds to the location information d. In this way
The location data storage unit 4 reads the location from the location information of the current location. The read location is displayed on the location display unit 6.

(2) If only the location name of the destination is known, but the position is not clear, in such a case, it is necessary to actually check it on the map, which is inconvenient when there is no map. According to the present invention, the location name input unit 5 inputs the location name of the destination. The location name input section 5 has a word processor function including an alphabet key and a numeric keypad. The location input section 5 once displays the location entered in the location name input section 5, and sends it to the location data storage section 4. This will be described with reference to FIG. This time, the position information is read from the target location, but as shown in FIG.
Multiple location information may correspond to one location such as b and c. The plurality of pieces of position information are sent to the GPS device 1 and compared with the position information of the user's current position, and the position information at the closest position is selected. Then, based on the selected position information, the distance and direction from the current position to the destination are calculated, and those data are displayed on the position information display unit 3.

[0012] Here, there is a problem of how much the location information and location in the location data storage unit 4 are divided into areas. First, with respect to the position information, it is possible to analyze up to a range of accuracy (for example, a unit of second) in which the GPS device 1 can perform positioning. The location should be divided into as many areas as possible (for example, □□ town or ○ chome range), but depending on the land, it may not be possible to divide the area so much that it is possible to recognize the location to some extent. Should be.

A CD-ROM is used as a memory of the system of the location data storage unit 4, and areas are divided into prefectures (prefecture units, Kyushu, Shikoku, etc.) within a certain range.
Make a CD-ROM for each area.

As described above, according to this embodiment, since the location data storage unit for storing the location information measured by the GPS receiver and the corresponding location data is provided, the location of the present location (location) The position information of the destination can be known by reading the position data in the location data storage unit by designating the destination position information in the destination name input unit.

[0015]

As is apparent from the above embodiments, according to the present invention, it is possible to confirm which location the user of the GPS device is currently located, and the location name of the destination is known. When the position is not clear, the position of the destination and the distance / direction can be clearly known. This is because even if you do not have a map, you can confirm the current location and the location of the destination, and in the event of an emergency in a land you do not know, you can confirm the current location (location) of the user. It is possible to provide a GPS location recognition device that enables quick contact.
