BEST MODE FOR CARRYING OUT THE INVENTION

Embodiment 1 FIG. FIG. 1 shows a configuration of a train operation support device according to an embodiment of the present invention. The same or corresponding parts as those of the conventional device shown in FIG. 5 are denoted by the same reference numerals. . This system is also roughly divided into a support data creation device 1 and a support data output device 2 as in the past, but in this example, the support data creation device 1 is mounted on each train together with the support data output device 2. While the train is running, curve data and gradient data, which are one of the support data, are automatically created. Reference numeral 16 denotes a GPS capable of measuring the heading and altitude, which is mounted on the roof of a running train and can measure the running direction and altitude of the train. 17 monitors the azimuth measured by the GPS 16, determines that there is a curve when the azimuth changes by a predetermined angle or more per unit time, and based on the kilometer information obtained from the distance detection unit 10, A curve start position information creating unit 18 for creating curve start position information using the point as a curve start position, and a curve start position information recording unit 18 for recording the curve start position information on a recording medium such as the FD6 or HD6a.
Also, 19 monitors the altitude measured by the GPS 16, judges that there is a gradient when the altitude changes by a predetermined value or more per unit time, and based on the km distance information obtained from the distance detecting unit 10. At that point as the slope start position,
A gradient start position information creating section for creating gradient start position information,
Reference numeral 20 denotes a gradient start position information recording unit that records the gradient start position information on a recording medium such as an FD or HD.

In the train driving support device configured as described above, the train is first run before starting commercial operation, and the support data generating device 1 is used to generate the support data. This is called a “measurement mode”. Thereafter, at the time of commercial operation, the created support data is transferred to the support data output device 2 to provide a driver or the like with a warning or the like. This is called “driving assistance mode (normal mode)”. At the beginning,
The operation of the support data creation device 1 in the “measurement mode” will be described with reference to the flowchart of FIG. First, stop the train to be measured at the running start position,
A column number is set (S1). At the same time, an initial value of about km is automatically set (S2). When the driver starts running the train (S3), the azimuth data and the altitude data from the GPS 16 attached to the roof of the train and the kilometer data from the distance detector 10 are collected (S4). When the train reaches the traveling end position (S5), the data collection ends. This data corresponds to each train.However, data is not collected for all trains present on the train schedule. The trains may be collected and later each train may be made to correspond to the collected data having the same running pattern.

The curve start position information creating section 17 creates curve start position information based on the collected azimuth data (S).
6). As shown in FIG. 3, the collected azimuth data is represented by a pair of azimuth and km, and the azimuth is "0" for north.
Degrees ”. From this azimuth data, for example, a point at which the azimuth changes by a predetermined angle or more per unit distance is detected and defined as “curved”. Conversely, when the azimuth does not change by more than a predetermined angle per unit distance, it is determined that the vehicle is passing through a straight line. In this way, the point at which the line is changed from "passing through the straight line" to "having a curve" is defined as the curve start position, and its distance is defined as curve start position information. The generation of the gradient start position information is the same as the generation of the curve start position information, and the gradient start position information generation unit 18 changes the altitude per unit distance to a predetermined value or more based on the collected altitude information. By detecting a point, gradient start position information is created (S
7). The created data is recorded on the FD 6 or the HD 6a (S7), and the process ends.

Next, the operation of the assistance data output device 2 in the "driving assistance mode" will be described with reference to the flowchart of FIG. First, the driving support data input unit 9 reads curve start position information and gradient start position information recorded on the FD 6, the HD 6a, or the like (Q1). Next, when the driver inputs the train number of the train to be driven from now on, driving support data corresponding to the train number is sent to the display output control unit 11 (Q2). When the train starts running (Q3), the display output control unit 11 sets the distance detection unit 10
The distance traveled from the starting station obtained from the station is constantly monitored, and the distance of the train at the starting station and the distance of the train calculated from the distance traveled are a predetermined distance before the distance recorded in the driving support data. Is reached (when YES in Q4), a warning display or voice output such as, for example, "It is 50m until the start of the curve" is displayed on the driver display 15 or the speaker 14 (Q5). The above processing is performed until the train arrives at the terminal station (Q6). As described above, since the driving support data can be automatically created simply by running the train, the trouble of inputting the data can be saved, and the data can be reliably recorded.

[0014]

Since the present invention is configured as described above, it has the following effects.

A train equipped with a GPS device capable of measuring direction and altitude is run from a traveling start station to an end station, and the running direction of the train is constantly monitored by the GPS device, and the running direction is equal to or more than a predetermined angle per unit time. When it changes to, the curve is determined to be "recorded" and recorded in the driving support data, so that it is not necessary to input the curve start position data, and the driving support data can be created reliably.

Further, when the train is in commercial operation, at the point where the train has reached a predetermined distance before the curve start position recorded in the driving support data, a warning of the driver approaching the curve is output to the driver. You can drive.

Also, the train altitude is monitored by the GPS device, and when the altitude changes over a predetermined value per unit time, it is determined that there is a "gradient" and recorded in the driving support data. Eliminates the need to enter data,
Driving support data can be created reliably.

Further, when the train is in commercial operation, a warning of approaching the gradient is output to the driver at a point where the train has reached a predetermined distance before the gradient start position recorded in the driving support data. Can drive.
