Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for monitoring and displaying the operation status of route buses, in which the operation status of each route bus can be grasped more reliably at each bus stop. The present invention relates to a route bus operation state monitoring and display method that can more reliably grasp the operation state of a route bus.

[0002]

2. Description of the Related Art In a conventional bus arrival time prediction system for a route bus, arrival guidance is provided by character information or voice to each bus stop (hereinafter simply referred to as a bus stop). For example, in the case of Japanese Patent Application Laid-Open No. 10-198989, each time a PHS portable device mounted on a route bus recognizes an ID from the nearest base station, a PHS portable device telephone number stored in advance corresponding to the ID. Calls the PHS portable device installed at the next bus stop,
When the approach information is transmitted, the fact that the route bus is approaching is displayed at the next bus stop. In the case of Japanese Patent Application Laid-Open No. 8-305996, while the bus identification information is periodically transmitted from the route bus from the low-power wireless transmitter, each of the bus stops where the bus identification information is received has the route bus. If it is related to the own bus stop, the distance to the route bus from the received electric field strength at that time, the arrival time to the bus stop is calculated from the distance, and the guidance display It has been provided to. Further, Japanese Unexamined Patent Publication No. 7-28543
In the operation information display system disclosed in Japanese Patent Publication No. 8 (1996), each train measures its own position using a GPS satellite and notifies the center via a communication satellite, while the center takes time to each stop station. After being requested, the information is transmitted and displayed at each of the stopping stations. However, regarding the estimated time of arrival at the destination, a position information notification system using radio waves from GPS satellites and a road traffic information providing system VICS (vehicle information
and communication system), the estimated time of arrival can be calculated almost accurately.

[0003]

However, in the case of the above-mentioned prior art, each of the route buses is, of course, until the user arrives at the bus stop. Since it is not possible to confirm what operating state the bus user is in, the bus user often waits for a long time at the bus stop. In general, it is difficult for the route bus itself to operate according to the timetable due to traffic conditions at that point in time, especially when it rains, traffic tends to be congested and its operation tends to be delayed. As a result, the user is often kept waiting for a long time at the bus stop.

[0004] A first object of the present invention is that at each bus stop,
It is an object of the present invention to provide a route bus operation status monitoring and display method that allows the status of each route bus to be more easily and reliably grasped without being affected by traffic congestion such as rainy weather. A second object of the present invention is to provide a route bus operation state monitoring and display method in which the operation state of each route bus can be more easily and reliably grasped even at bus stops.
A third object of the present invention is to provide a method for monitoring and displaying the operation status of a route bus at each bus stop, in which the actual operation position of each route bus can be more easily and reliably grasped. A fourth object of the present invention is to provide a non-bus stop,
Not only can the operation status of each route bus be more easily and reliably grasped, but at each bus stop, the actual operation position of each route bus can be more easily determined.
Another object of the present invention is to provide a route bus operation state monitoring display method that can be reliably grasped.

[0005]

A first object of the present invention is to provide a bus stop in which a scheduled arrival time is displayed in advance in correspondence with a bus ID, and in each of the bus stops, a bus passage is detected at the bus stop. Each time the pass position for the corresponding bus ID is stored and displayed as the bus stop, the information is wirelessly transmitted to the downstream adjacent bus stop as bus passing information,
Each time the passed bus information is received from the upstream adjacent bus stop, the passing position for the corresponding bus ID is stored and displayed as the upstream adjacent bus stop, and is also wirelessly transmitted to the downstream adjacent bus stop as the bus passed information. Every time an arrival time at the bus stop calculated based on the GPS satellite position measurement result transmitted by radio from the GPS stop is received, the arrival time is corrected by the traffic amount separately detected at the bus stop. This is achieved by being stored and displayed as a state in which it has been set.

[0006] In addition to the above, the above-mentioned second object is also provided that every time there is a bus operation status inquiry request from a PHS portable device to a PHS base station installed at each bus stop, the various information stored in the bus stop is selected. Is partially read out selectively, and the PHS of the inquiry request source is directly sent from the PHS base station.
This is achieved by transmission and display on the HS portable device.

A third object of the present invention is to provide a system in which the scheduled arrival time is displayed in advance at each bus stop in correspondence with the bus ID, and the radio is periodically transmitted from each operating bus.
Each time the position measurement result of the bus by the PS satellite is received at each bus stop, the position measurement result is displayed at the bus stop as a spot corresponding to the bus ID on the map.

A fourth object of the present invention is to provide a method for monitoring and displaying the operation status of a route bus at each bus stop, wherein the scheduled arrival time is displayed in advance at each bus stop in correspondence with the bus ID. In each case, each time a bus passage is detected at the bus stop, the passing position for the corresponding bus ID is stored and displayed as the bus stop, and is wirelessly transmitted to the downstream adjacent bus stop as bus passing completed information, and is transmitted from the upstream adjacent bus stop. Each time a bus passed information is received,
The passing position for the corresponding bus ID is stored and displayed as the upstream adjacent bus stop, and is wirelessly transmitted to the downstream adjacent bus stop as information indicating that the bus has passed, and is periodically transmitted wirelessly from each operating bus. Each time the position measurement result and the arrival time at the bus stop calculated based on the position measurement result are received, the arrival time is stored and displayed as a state corrected by the traffic amount separately detected at the bus stop. At the same time, the position measurement result is displayed as a bus ID-corresponding spot on the map, and is stored in the bus stop every time there is a bus operation status inquiry request from the PHS portable device to the PHS base station installed at the bus stop. Some of the various types of information are selectively read out, and the PHS of the inquiry request source is directly sent from the PHS base station.
This is achieved by being transmitted and displayed on the portable device.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. First, the operation status monitoring and display system of a route bus according to the present invention will be described.
FIG. 1 shows a system configuration in one example.
As shown in the figure, the system includes a plurality of running buses 3 whose position information can be confirmed by a GPS satellite 13.
And a plurality of bus stops 10 to 12 scattered along the operation route, a general PHS base station 1 (1a to 1c) installed at each of the bus stops 10 to 12, and a PHS base station 1 as necessary. And the PHS portable device 2 which can be accessed at any time. Bus stop 1
Each of the bus information transmitting and receiving units 8
(8a-8c), passage sensor 7 (7a-7c), map information display unit 14 (14a-14c), timetable 4 (4a-4)
c), the operation unit 6 (6a to 6c), the processing unit 5 (5a to 5c)
c) and a database 9 (9a to 9c).

[0010] Here, the system components will be described more specifically. In each of the PHS base stations 1a to 1c, as shown in FIGS.
2 Daily bus operation status in each database 9a-9
c, a bus operation status inquiry request from the user is read out from the databases 9a to 9c and transmitted to the processing units 5a to 5c. Updating of data on the databases 9a to 9c is permitted. The databases 9a to 9c include, for example, a bus ID for identifying each running bus 3 on a route, a passing position indicating a passing stop position, a scheduled arrival time indicating an arrival time on an original timetable, an arrival time changing in real time, And the boarding rate indicating the degree of congestion in each running bus 3.

In the bus information transmitting / receiving sections 8a to 8c, the passing position information wirelessly transmitted from the upstream adjacent bus stop, the boarding rate and the arrival time (G) wirelessly transmitted from each running bus 3 are transmitted.
Each time the PS satellite 13 receives the real time (calculated based on the position measurement result of the bus 3 itself) during operation,
While a processing request event is generated for the processing units 5a to 5c, the bus information transmission / reception units 8a to 8c send a command to each of the processing units 5a to 5c to a downstream adjacent bus stop.
The data is transmitted wirelessly.

The passage sensors 7a to 7c acquire a bus ID when detecting that the running bus 3 has passed this stop, generate a processing request event to the processing units 5a to 5c, and Is detected, and the calculation units 6a to 6c are periodically notified.

The time tables 4a to 4c are, as shown in FIG.
It comprises a timetable display section 18 and a display panel of a bus information display section 19. Of these, a circle symbol displayed on the time display section 18 indicates guidance of a passed bus, and a square symbol indicates that the bus has already departed and is operating on the route. On the other hand, the bus information display unit 19 focuses on the running bus 3 indicated by the □ symbol in the timetable display unit 18, and the passing position, the scheduled arrival time, the arrival time, and the occupancy rate are indicated on the line. Is displayed. The display contents on each of the display panels can be changed in real time by instructions from the processing units 5a to 5c.

The computing units 6a to 6c monitor the traffic volume. When the arrival time is wirelessly transmitted from the operating bus 3 as input information, the arrival time is determined in consideration of the traffic volume. The output is corrected.

In the processing units 5a to 5c, predetermined processing is performed by processing request events from the bus information transmitting and receiving units 8a to 8c and the passage sensors 7a to 7c.
The processing operations at a to 5c will be described below with reference to FIGS.

That is, if a processing request event occurs to the processing units 5a to 5c, if the event is from the running bus 3, the arrival time from the running bus 3 to the arithmetic units 6a to 6c Is issued to correct. Further, the data updating process shown in FIG. 4 is started for the databases 9a to 9c of the PHS base stations 1a to 1c as a common process. In this data update process, after a bus ID to be updated is searched, a process corresponding to an event is performed. As shown in the figure, in the case of an event from the passage sensors 7a to 7c, "passed" is set on the data line corresponding to the corresponding bus ID. In the case of an event from an upstream adjacent bus stop, a passing bus stop position is set on the data line corresponding to the corresponding bus ID, and in the case of an event from the operating bus 3, the data line corresponding to the corresponding bus ID is set. Above, the (corrected) arrival time and the occupancy rate are set. Thus, after the databases 9a to 9c are updated,
Under the initiative control of the processing units 5a to 5c, the database update contents are wirelessly transmitted to the downstream adjacent bus stop.

The PHS portable device 2 sends a bus operation status inquiry request to the PHS base station 1 to transmit bus operation status information,
For example, as shown in FIG. 5, the operation status on the bus information display unit 19 can be acquired as character information.
FIG. 5 shows an operation sequence with the PHS base station 1 when a bus operation status inquiry request is made from the HS portable device 2. If the user issues a bus operation status inquiry request from the PHS portable device 2 as needed, the PHS base station 1 reads the bus operation status information from the database 9 as desired based on the request. Is returned to the PHS portable device 2 as a direct inquiry response without going through the PHS portable device 2 so that the character information of the bus operation status information can be displayed on the PHS portable device 2.

In the case where the position measurement result of the bus 3 by the GPS satellites 13 is periodically transmitted by radio from each of the buses 3 in operation, the bus information is displayed on the map information display section 14 at each of the bus stops 10 to 12. The position of each bus 3 can be displayed. Whenever the bus position measurement result is received at each of the bus stops 10 to 12, the position measurement result is displayed at the bus stop 10 to 12 as a bus ID corresponding spot on a map as shown in FIG. 7, for example. , User is operating bus 3
Each operation position is easily known. FIG.
In the middle and black circle positions 21, the own bus stop position and the white circle position 22
Indicates the other bus stop position, and the white circle mark position 23 indicates the position of each bus 3 in operation.

Finally, the operation of the operation status monitoring and display system will be briefly described as follows. That is, assuming, for example, that the bus 3 passes through the bus stop 12, a processing request event by the passage sensor 7 c occurs in the processing unit 5 c, and the processing unit 5 c causes the database 9 to operate.
After the passage position data corresponding to the corresponding bus ID on c is updated and set to have passed this stop, the updated content is wirelessly transmitted from the bus information transmission / reception unit 8c to the downstream adjacent bus stop 11 under the control of the processing unit 5c. Is what it is. At the downstream adjacent bus stop 11, a processing request event by the bus information transmitting / receiving unit 8b is generated in the processing unit 5b in accordance with the reception of the updated content, and the processing unit 5b causes the processing unit 5b to execute the database 9b
After the passing position data corresponding to the corresponding bus ID is updated and set to have passed the stop, under the control of the processing unit 5b,
The updated content is wirelessly transmitted from the bus information transmitting / receiving unit 8b to the downstream adjacent bus stop 10. Since the updated content has been received, the same processing is performed at the downstream adjacent bus stop 10.

The operating bus 3 passing through the bus stop 12
From this time, the arrival time by the GPS satellite 13 and the occupancy rate of the bus are wirelessly transmitted to the downstream adjacent bus 11. If the information is received by the bus information transmitting / receiving unit 8 b of the downstream adjacent bus 11, the processing request event is processed. Generated in the section 5b,
b, the scheduled arrival time is corrected, and after the corresponding arrival time and the occupancy rate data on the database 9b are updated, the updated content is wirelessly transmitted from the bus information transmitting / receiving unit 8b to the downstream adjacent bus 10. Has become. As a result, the same processing is performed on the downstream adjacent bus 10, and the database 9a is updated as desired.
