Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a route bus guide device that guides passengers to the stops where route buses stop.

[Summary of the invention]

In the present invention, information regarding maps and bus stops is stored in a predetermined memory that can be randomly accessed, and when the current location of the bus, which is detected independently, reaches the vicinity of a stop on a predetermined route, guidance is automatically announced. be done.

[Background technology]

Conventional route buses play back pre-edited magnetic tapes for each route to guide passengers to the next stop.

For this reason, the driver of the route bus manually operates the switch each time immediately after leaving the bus stop or shortly before arriving at the bus stop to put the magnetic tape into playback mode. When a preset predetermined time has elapsed or when a predetermined marker is detected, the playback operation is automatically terminated.

[Problem that the invention seeks to solve]

In this way, the conventional system records information on magnetic tape, which not only takes a lot of effort to compile, but also requires preparing a different magnetic tape for each route, which means that the same bus does not always follow the same route.

Find the tape that corresponds to the route the driver will be traveling on that day,
This was inconvenient as it had to be installed on the bus before it could go into service.

In addition, since the driver has to operate the driver each time, there is a risk that the driver will be burdened, which may impede safe driving.

Therefore, the present invention is intended to automatically provide guidance without requiring much effort from the driver.

[Means for solving problems]

The present invention provides a route bus guide device that includes a randomly accessible memory that stores at least map information regarding a plurality of routes on which buses travel, information regarding a plurality of bus stops on the map, and an independent memory that stores the current location of a bus on a map. The present invention is characterized in that it includes a detection means for detecting the current location, and a control circuit that makes a guidance announcement when the current location reaches a predetermined relationship with a stop on a predetermined route.

[Effect]

The randomly accessible memory stores at least a map of a plurality of routes along which the bus travels and information regarding a plurality of stops on the map. The detection means autonomously detects the current location of the bus on the map. For example, when the current location reaches the vicinity of a stop on a predetermined route, the control circuit makes a guidance announcement.

〔Example〕

FIG. 1 is a block diagram of a route bus guide device of the present invention. This device is pre-installed on the bus.

The driver operates the input means 4 before operating the bus.

First of all, start position i! Enter (your current location). At the bus stop where a route bus stops, 1 For example, as shown in Figure 5, the name of the stop (for example, 000 station front) and the number (including symbols, etc.) assigned to each stop are posted. 6 For example, the starting position When (the current location of the bus) is the stop location A on the route map shown in FIG. 3, the number A1 is input. This location A is, for example, a bus garage (one of the stops)
Often, but not necessarily.

Next, the driver operates the input means 4 to input the route to be traveled on that day. Now, as shown in FIG. 3, since the starting position is position A1, route A is input.

Rank E! Since there is no other route starting from A t, inputting the route may be omitted in such a case. That is, the memory 5 stores in advance information about all (plural) routes of the company to which the bus belongs, information about the map (road) about the route, and information about the plurality of stops on the map. Therefore, when a start position is input from the input means 4, the control circuit 3, which is made up of a microcomputer or the like, may search for a route that includes the start position (stop).

However, if the starting position is, for example, position AI (B-), there are two routes that include this position. Therefore, in such a case, one of the routes is input.

Randomly accessible memory 5 is, for example, RAM or CD.
- It includes a ROM, etc., and the input start position and route are stored in the RAM, for example.

When the route is determined, the control circuit 3 controls the destination guide means 12 via the drive circuit 11, and in this case the positions ff1A,
Display as the destination. If the destination guide means 12 is composed of, for example, a piece of cloth with a plurality of destinations printed on it, a motor (not shown) is rotated, and the destination guide means 12 is configured to have a plurality of destinations printed on it, for example, cloth or the like. A
Selectively display the name of I.

Of course, this destination guide means 12 can also be configured by an electronic bulletin board or the like. This destination guide means 12 is usually provided at the upper front of the bus so that one passenger can easily determine the destination of the bus from the outside.

When the destination AG is displayed on the destination guide means 12, the control circuit 3 controls the generating circuit 8 to make the speaker 10 announce the name (or route number, etc.) of the destination A by voice. The speaker 10 is placed near the driver's seat, so that the driver can confirm the display of the destination guidance means 12 from inside. The audio signal is stored in C that constitutes the memory 6.
It is possible to store it in advance in a D-ROM or the like and reproduce it, or it is also possible to use a voice synthesis IC or the like as the 1 generation circuit 8.

The detection means 1 detects the running direction of the bus from, for example, the earth's magnetism, and the detection means 2 detects the traveling distance from the rotation of the tires of the bus. The control circuit 3 calculates and detects the current location of the bus based on the start position from the output of the detection means 1.2 (
Of course, this calculation can also be made to be performed by the detection means 1.2).

In other words, the current location is detected independently. It is also possible to detect the current location separately by using a GPS device or by receiving radio waves emitted from a bus stop, but doing so would complicate the configuration and increase costs. There, the current location is detected autonomously.

The control circuit 3 is on the selected route. Memory 5 stops that are the same as the current location or behind the current location and stops in front of the current location
, and set each as the first (rear) stop Syu and the second (front) stop S2.

At this time, the control circuit 3 controls the generation circuit 6 to stop S8.
and 82 names are generated as images (characters) (of course, these data can also be stored in a CD-ROM) and displayed on a display means 7 such as a CRT. When the bus is running towards A4, the first place WI is as shown in Figure 4.
The names of A and A are displayed. Also, at this time, the control circuit 3 calculates the distance between the positions A and A4, and the ratio of the current location to this distance (distance of travel), and displays them as well. This not only allows passengers to visually know the names of the previous and next stops (useful in case they miss the audio display described below), but also allows passengers to see the names of the previous and next stops. You can tell which side of the road you are driving between. The display means 7 is disposed, for example, above and behind the driver's seat, facing rearward.

Furthermore, the control circuit 3 calculates the distance between the rear bus stop S and the current location. When the distance L exceeds a predetermined reference value l1, the stop S2 in front becomes the turning point (destination guidance means 1
2) is the point at which it is necessary to change the display. For example, right now the bus is from position II to position 1! t
A, when you're heading towards the place! ! Since A is not a turning point, the generation circuit 8 generates a message such as "For example, the first order is A."

An announcement is made from speaker 9. The speaker 9 is placed at a position where passengers on the bus can easily hear the sound, for example, on the ceiling inside the bus.

For example, the bus is from position 'il As to position i! When I was heading towards As! Since 8* is a turning point, the destination guidance means 12 is controlled via the drive circuit 11, and the destination guidance is 1! A, from position Ia! Changed to Ai. As a result, passengers waiting at location 1iiA for a bus headed in the direction of location A1 can correctly know the destination of the bus.

At the same time as the destination guidance is changed, a predetermined audio display (for example, an announcement such as "The first stop is at the last stop ooo") is also performed, as in the case described above.

Next, the distance between the stop S2 in front and the current location is calculated, and when the distance L8 becomes less than a predetermined reference value of 12 (when it comes close to 8 next stops), the 1 generation circuit 8 outputs 1, for example, 1 "This is A, please press the buzzer if you want to get off the train.", etc., is output and an announcement is made from the speaker 9. The reference value l is set in consideration of the time required for the passenger to operate the buzzer 14 when getting off the vehicle.

When the next stop S2 is a turnaround point, the bus always stops there, so the buzzer 14 is not operated and the lamp 1
3 is lit to indicate that the bus is stopping.

When the next stop S8 is not a turning point, the control circuit 3 starts a built-in timer. When a passenger operates the buzzer 14 before the predetermined time has elapsed.

The control circuit 3 causes the generation circuit 8 to generate a buzzer sound followed by an audio signal, and from the speaker 9, for example, the first vehicle stops.
etc., and lights up the lamp 13.

When the buzzer 14 is not turned on even after a predetermined period of time has elapsed,
Control circuit 3 controls generation circuit 8, and the primary passes through,
” etc. is emitted from the speaker 9.

When the current location becomes equal to the stop S2 (when the stop S8 is reached), the previous stop S2 is newly set as the stop S1, and the next stop is searched and set as the new stop S2.

The same operation is repeated thereafter.

The above operation is shown in a flowchart as shown in FIG.

If the distance traveled on the route is long and the display deviates from the current location, the driver can reset the error by simply re-entering the number of that stop as the starting position when the driver stops at a designated stop. . Of course, other automatic correction means may also be provided.

In the above, the next stop is specified by inputting not only the current location (starting position) but also the route, but it is also possible to select the next stop based on the direction in which the bus is traveling.

For example, in FIG. 3, when the current location is A, and the driver is heading toward A3, the next stop can be specified as A3 since there are no other stops (roads). However, place 1i
fA, to position A.

If you are heading towards A4., the next stop is A4. It is not possible to specify whether the stop is B or . In such a case, if there is a stop near intersection C, an announcement will be made almost every time the user arrives at the stop, which is somewhat inconvenient, but it is possible to omit entering the route.

Map information does not change frequently, but routes and stops may be expanded, changed, or deleted.

Therefore, map information may be stored in a CD-ROM or the like, and route and stop information may be stored in a solid-state memory, an IC card, or the like. Any type of memory that allows random access to arbitrary data may be used.

〔effect〕

As described above, the present invention relates to a route bus guide device.

A randomly accessible memory that stores at least map information regarding a plurality of routes along which the bus travels and information regarding a plurality of stops in the map.

The bus is equipped with a detection means that autonomously detects the current location on the map, and a control circuit that announces guidance when the current location reaches a predetermined relationship with a stop on a predetermined route. There is no need for special operations to provide guidance while driving. Since the memory only needs to be the same, it can be duplicated in large quantities and costs are reduced.
