Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle stop position guidance broadcasting device used in various transportation facilities.

[0002]

2. Description of the Related Art In various transportation means, vehicle stop position information such as the next stop location name is broadcast in the vehicle. For example, in a route bus, each bus company records each stop position information along the operating route on a cassette tape, and prepares such a cassette tape for each operating route for the number of vehicles. The driver sets the cassette tape corresponding to the route to the stop guide broadcasting device at the start of the operation, and broadcasts the next stop name by manual operation every time it passes the stop.

[0003]

However, in the conventional vehicle stop position guide broadcasting apparatus using the cassette tape as the vehicle stop position information recording means as described above, reproduction, stop, etc. of the cassette tape are performed only by the manual operation of the driver. Since it is performed, when you set it in the device, you may set it without noticing that it has not been rewound, or as a result of forgetting operation etc., the current running position and the stop position information may not correspond .

At this time, since it takes time to fast-forward and rewind, there are problems that the operation time is disturbed due to operation, and of course operations during driving are dangerous, and the traveling position and the stop position information correspond. There was a case that it would run to the end point without doing so.

As described above with reference to the case of the route bus, the conventional stop position guidance broadcasting device has a problem that the necessary information is not always accurately guided because the operation is complicated and manual operation is required. there were.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems and to provide a stop position guide broadcasting device which is simple and can always provide accurate stop position guide.

[0007]

In order to achieve the above object, in a stop position guide broadcasting apparatus according to the invention of claim 1, a stop position guide broadcasting apparatus for performing stop position information of a vehicle by the in-vehicle broadcast. In the above, a CD-ROM storing each stop position information in order of operation for each one or a plurality of operation routes of the vehicle, and a search means for searching the CD-ROM to selectively extract the operation route of the vehicle, And a reproducing means for reading out a next stop position information signal of the vehicle and outputting it to the broadcasting means based on the position information signal outputted from the recognizing means. is there.

According to a second aspect of the invention, there is provided a stop position guidance broadcasting device according to the first aspect of the invention, wherein in the stop position guidance broadcasting device according to the first aspect, the recognizing means is provided with the position information provided at each stop position. It has a display reading means for reading the display shown.

Further, in the stop position guidance broadcasting device according to the invention described in claim 3, in the stop position guidance broadcasting device according to claim 1, the recognition means receives a signal from the global positioning system. It has a receiving device and a calculating means for calculating the current position of the vehicle based on the received signal from the receiving device.

[0010]

In the stop position guidance broadcasting device of the present invention, first, the search means searches the CD-ROM storing the stop position information for each one or a plurality of operation routes in order of operation, and selects and extracts an arbitrary operation route. The reproducing means reads out the next stop position information signal of the vehicle and outputs it to the broadcasting means based on the position information signal output by the recognizing means recognizing the current position.

Therefore, according to the present invention, by using a CD-ROM having a very large capacity as compared with the cassette tape for the storage means, all the operation routes are stored and the stop position information of the operation route necessary at the start of the operation. Not only can you automatically search for and extract, but also you can recognize the current position and read the next stop position information according to the running of the vehicle, so you can replace different tapes for each route, fast forward / rewind as before. The traveling position and the stop position information always correspond to each other without requiring a complicated manual operation such as, and accurate stop position guidance is performed.

Further, as a means for recognizing the current position of the vehicle,
It is possible to accurately recognize the current position (closest stop position) by providing a display such as a bar code indicating the position information at each stop position and reading it by a display reading means such as a bar code reader. Therefore, if the display cannot be read as the vehicle travels, that is, the next stop position information is read at a time when the vehicle passes the stop position having the display and is separated by a predetermined distance, the next stop position information is accurately guided. You can broadcast. The delay means for this purpose may be a time delay means such as a timer or a distance delay means linked with a vehicle odometer.

As a means for recognizing the current position of the vehicle, a global positioning system, so-called GPS (Global Positioning S
It is also possible to obtain accurate stop position information by using ystem). That is, the current position of the vehicle is calculated by the calculating means based on the GPS signal received by the GPS signal receiving device, and the current position and a predetermined position (definition position) in the operation route stored in the CD-ROM. By comparing the information with the information, it is possible to read out and reproduce the information on the stop position currently aimed at by the vehicle.

As a first embodiment, FIG. 1 shows a stop position guidance broadcasting device for a route bus using a bar code as a recognition means. This route bus vehicle 1 is equipped with a bar code reading device 2 connected to a CD-ROM searching and reproducing means (not shown). The automatic destination display device 4 is interlocked with the stop position guide broadcasting device to display the stop position name simultaneously with the guide broadcast. The stop position guide system according to the present embodiment will be described below with reference to the flow chart FIG. 2 and the schematic operation diagram 3 of the CD-ROM.

As shown in FIG. 2, at the start of operation (S101), the electric destination display device 4 is operated from the inside of the bus vehicle 1 to select an operation route (S102) and selected from the CD-ROM (FIG. 3a). The stop position information corresponding to the operation route is searched (S103). First, the head portion of the stop position information of the selected operation route is read out (FIG. 3b), and the vehicle is temporarily stopped.

The vehicle 1 is run and the bar code reading device 2 is operated (S104). This is repeated until the barcode 3 provided at the stop position can be read by the barcode reading device 2 (S106). Scanned barcode 3
When it is determined that is the starting point, the vehicle 1 is repeatedly read until the bar code 3 becomes unreadable because the vehicle 1 travels a certain distance from the bar code 3 (S107).
If it cannot be read, the first stop position information is read from the CD-ROM (Fig. 3c) and the in-vehicle broadcast (S10) is performed.
9), and the reproduction operation is temporarily stopped (S110, FIG. 3).
d). Then, the reading operation of the barcode 3 is restarted (S105).

When the vehicle 1 further travels and approaches the next stop position, the bar code there is newly read. If the read bar code is not at the starting point or the ending point (S108), the reading operation of the CD-ROM is restarted (FIG. 3e), the next stop position information is read out, and the in-vehicle broadcast (S109) is performed to perform the reproducing operation. Pause (S11
