Abstract

Embodiments of the present invention are directed to a technology for timely reporting on vehicle positions to a control center without unnecessary spending on communication costs. The positions of a plurality of moving bodies which are being managed are detected. Determinations are made on whether or not the positions of these moving bodies are within specified multi-stage distance ranges (S100 to S200 to S500). As a result of this determination, when the position of the moving body enters into a distance range for one of the stages, the position of this moving body is wirelessly reported to a control center 200 (S600).

Claims

1. A mobile system to be installed in a vehicle monitored by a vehicle position management system having a detection device configured to detect a position of the vehicle, the mobile system comprising:

a storage module configured to store a plurality of checkpoints associated with a planned route of the vehicle;

an evaluation module configured to evaluate whether or not a vehicle position obtained from the detection device of the vehicle position management system is within a predetermined distance range organized as a plurality of stages from the checkpoint; and

an output module configured to generate and output a signal based on evaluation by the evaluation module to provide wireless reporting of the vehicle position to a control center of the vehicle position management system when the vehicle position enters the distance range of one of the stages.

2. The mobile system of claim 1 wherein the output module is configured to generate and output a signal, if the evaluation module indicates that the vehicle position is outside the predetermined distance range, to provide wireless reporting of the vehicle position to the control center of the vehicle position management system at predetermined time intervals.

3. The mobile system of claim 2 wherein the storage module is configured to receive from the control center operations settings data containing the planned route and the checkpoints and to store the operations settings data, when the output module generates and outputs the signal to provide wireless reporting of the vehicle position to the control center.

4. The mobile system of claim 1 wherein the storage module is configured to receive from the control center operations settings data containing the planned route and the checkpoints and to store the operations settings data, when the output module generates and outputs the signal to provide wireless reporting of the vehicle position to the control center.

5. A mobile system to be installed in a vehicle monitored by a vehicle position management system having a detection device configured to detect a position of the vehicle, the mobile system comprising:

a storage module configured to store a plurality of checkpoints associated with a planned route of the vehicle;

an evaluation module configured to evaluate whether or not a vehicle position obtained from the detection device of the vehicle position management system is within a predetermined distance range organized as a plurality of stages from the checkpoint; and

an output module configured to generate and output a signal, if the evaluation module indicates that the vehicle position is outside the predetermined distance range, to provide wireless reporting of the vehicle position to the control center of the vehicle position management system at predetermined time intervals.

6. The mobile system of claim 5 wherein the output module is configured to generate and output a signal based on evaluation by the evaluation module to provide wireless reporting of the vehicle position to a control center of the vehicle position management system when the vehicle position enters the distance range of one of the stages.

7. The mobile system of claim 5 wherein the storage module is configured to receive from the control center operations settings data containing the planned route and the checkpoints and to store the operations settings data, when the output module generates and outputs the signal to provide wireless reporting of the vehicle position to the control center.

8. A vehicle position management system comprising:

a detection device configured to detect a position of the vehicle;

a mobile system which includes;

a mobile system storage module configured to store a plurality of checkpoints associated with a planned route of the vehicle;

an evaluation module configured to evaluate whether or not a vehicle position obtained from the detection device of the vehicle position management system is within a predetermined distance range organized as a plurality of stages from the checkpoint; and

a mobile system output module configured to generate and output a signal based on evaluation by the evaluation module to provide wireless reporting of the vehicle position when the vehicle position enters the distance range of one of the stages; and

a vehicle position control system which includes;

a control system storage module configured to store operations settings data including the planned route of the vehicle and the plurality of checkpoints associated with the planned route;

a monitoring module configured to detect when the output module generates and outputs the signal to provide wireless reporting of the vehicle position; and

a control system output module configured to read and wirelessly send the planned route and the operations settings data to the mobile system when the output module generates and outputs the signal to provide wireless reporting of the vehicle position as detected by the monitoring module.

9. The vehicle position management system of claim 8 wherein the mobile system output module is configured to generate and output a signal, if the evaluation module indicates that the vehicle position is outside the predetermined distance range, to provide wireless reporting of the vehicle position to the control center of the vehicle position management system at predetermined time intervals.

10. The vehicle position management system of claim 8 wherein the mobile system storage module is configured to receive from the control system output module operations settings data containing the planned route and the checkpoints and to store the operations settings data, when the output module generates and outputs the signal to provide wireless reporting of the vehicle position.

11. A method for managing vehicles, comprising:
