Abstract

PROBLEM TO BE SOLVED: To obtain a destination guide device which easily executes guide to a destination which doesn't have information specified by latitude and longitude. SOLUTION: A reference area having a reference point specified by longitude and latitude is successively divided based on prescribed regularity to obtain divided areas and subdivided areas; and when destination information including codes which discriminate the reference area, a divided area, and a subdivided area respectively is inputted, longitude and latitude of the destination of movement specified by this destination information are successively calculated from the reference point, and a worker is guided to this destination of movement based on the calculation result. Therefore, the destination of movement is obtained with a very small information volume of longitude and latitude without preparing information related to longitude and latitude of each destination of movement, and GPS is interlocked to guide the worker.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a satellite positioning system (Glob).
The present invention relates to a destination guidance device for guiding to a destination using an al positioning system (GPS), and particularly to a destination guidance device for guiding to a destination that does not have individual latitude / longitude information.

[0002]

2. Description of the Related Art Conventionally, there is a navigation system shown in FIG. 6 as this kind of destination guidance device. In this navigation system, a reception unit 101 receives a signal loaded from a GPS and transmits a current position of the vehicle from a GPS via an antenna 100, and a latitude and longitude stored in a memory 103 in advance based on the reception signal. The calculation unit 102 calculates the current position on the map from the map information specified by
The present position is displayed on the display unit 104 in association with the map data. The memory 103 is a CD-RO
Map information specified by latitude and longitude is recorded in a large-capacity storage device such as M.

[0003]

Since the conventional navigation system as a destination guidance device has been constructed as described above, it must be map information specified by latitude and longitude stored in the memory 103 in advance. For example, there is a problem that a destination cannot be specified and a vehicle or the like cannot be guided to the destination. That is, position information other than map information specified as latitude and longitude, for example, identification codes indicating the location of utility poles, electric wires, gas pipes, or electric or gas equipment cannot be displayed on a map in conjunction with GPS. .

A utility pole, electric wire, gas pipe or electric or gas equipment indicated by the identification code indicating the location is referred to as a G.
If it is attempted to display on a map in conjunction with the PS, it is necessary to add and specify map information specified by latitude and longitude for each identification code, and the data amount of the map information becomes enormous, It becomes impossible to configure as a simple system.
