Abstract

PURPOSE:To obtain a GPS receiver capable of calculating the optimum direction and distance to a station of public transportation from the self-position. CONSTITUTION:By receiving the signal from the GPS satellite and using the self-position calculated in a GPS engine part 1 and the station position contained in a station information storage part 3, the direction and distance of a station from the self-position are calculated in a controller 2 and the result is indicated on a display 5.

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention applies to GPS (Global
(Positioning System) receiver.

2. Description of the Related Art There is no GPS receiver that displays the direction and distance between the user's location and the location of a public transportation platform (for example, a railway station). Some on-vehicle GPS receivers display the location of stations and airports on CRTs, etc., along with other landmarks.

0003

[Problem to be solved by the invention] In general, public transportation is often used on foot rather than by car, and with conventional methods, it is unavoidable that the device becomes larger. There was a problem that it could not be used.

[0004] The present invention solves the above-mentioned problems, and aims to provide a GPS receiver that can determine the direction and distance of the optimal public transportation stop at the user's location.

[0005]

[Means for Solving the Problems] In order to achieve the above object, the present invention provides an antenna section integrated in a device for receiving signals from GPS satellites, and a device for determining one's own position by analyzing the signal. a GPS engine unit for calculation; a boarding/disembarkation location storage unit storing information on the locations of public transportation platforms; an input unit for inputting instructions regarding the operation of the device; and the GPS engine unit. a control unit that calculates the direction and distance from the calculated self-position and the position of the boarding/disembarking station stored in the boarding/disembarkation location storage unit, and controls the operation of the device; and a control unit that controls the operation of the device and the direction/distance to the self-position determined by the control unit. The device is equipped with a display device that displays , and a battery built into the device.

[0006]

[Operation] With the above configuration, this device can specify its own position using GPS, calculate the direction and distance from that point to the nearest station, etc. stored in advance, and display the results.

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 a GPS receiver according to an embodiment of the present invention. 1 is a GPS engine unit that receives signals from GPS satellites (not shown), calculates its own position by analyzing the signals, and outputs position information in terms of latitude and longitude; 3 indicates the position of a railway station in latitude and・Station information storage unit that stores the longitude and station name and track name; 4 is an input unit for inputting instructions regarding the operation of the device; 2 is a storage unit for self-location information and station information obtained by the GPS engine unit 1; A control section inputs the station location information stored in section 3 and calculates the direction and distance; 5 a display section that displays the calculation results calculated by the control section 2 and the station name and track name of the relevant station;
6 is an antenna for receiving signals from GPS satellites;
7 is a NiCd battery that supplies power to the device.

The operation of the GPS receiver having the above-mentioned constituent blocks will be explained below.

First, at a point where the location of a station is desired, an instruction to search for the nearest station is given to the control unit 2 via the input unit 4. The control unit 2 receives data obtained by receiving and analyzing signals from GPS satellites by the GPS engine unit 1 via the antenna 6, and determines its own position. Let the positioning result of the own position be the latitude YR and the longitude XR. Further, the control section 2 takes in the position information of each station from the station information storage section 3 as latitude YB and longitude XB. The control unit 2 performs calculations according to the flowchart in FIG. 2 to determine the direction and distance of each selected station from its own position. As a result, the station closest to the user's location is selected and the direction, distance, station name, and track name of that station are displayed on the display unit 5 (display example: FIG. 3). Furthermore, by issuing an instruction using the input unit 4, it is also possible to perform a similar display for the next closest station. Therefore, the direction of the station can be determined from the azimuth using a compass, etc., and the distance and
You can search for the most suitable station by knowing the station name and track name.

[0011] As described above, according to the GPS receiver of the embodiment of the present invention, the own position can be specified using GPS, and the direction and distance to the nearest station can be displayed based on the stored station position information.

0012

[Effects of the Invention] As is clear from the above embodiments, according to the present invention, it is possible to measure one's own position using GPS, and to determine the direction and distance of the nearest public transportation stop from that point. It is possible to provide an excellent GPS receiver that can greatly improve the convenience of using public transportation by knowing where to get on and off the public transportation.
