DETAILED DESCRIPTION OF THE INVENTION
Embodiment 1 FIG.
FIG. 1 is a block diagram showing a configuration of a railway vehicle driving training simulator according to Embodiment 1 of the present invention.
In FIG. 1, a cab 1 operates a driving training simulator for a railway vehicle. The simulation calculation unit 2 simulates the operation speed based on the operation command of the cab 1. The forward route image reproduction device 3 records the route image in front of the driver's cab from the first station to the last station where the simulation is performed, and reproduces the forward route image according to the driving speed output by the simulation calculation unit 2. The forward route image display means 4 includes a video projector 4a and a screen 4b. The side image reproduction device 5 records a side image obtained by photographing the cab side surface at a constant speed in advance, and reproduces the side image according to the traveling speed according to the traveling condition. The video switcher 6 switches between the side image and the blackback image. The side image display means 7 includes a video projector 7a and a screen 7b. The lower surface image reproduction device 8 records a front lower surface image obtained by photographing the lower front portion of the cab in advance at a constant speed, and reproduces the front lower surface image in accordance with the traveling speed according to the traveling condition. The video switcher 9 switches between the front lower surface image and the blackback image. The lower surface image display means 10 includes a video projector 10a and a screen 10b.
[0008]
When the driving training simulator for a railway vehicle configured as described above performs a driving operation on the cab 1, the simulation calculation unit 2 calculates the traveling speed, position, and the like of the train according to the contents of the driving operation. Based on the above, the playback speed of the front route video playback device 3, the side video playback device 5 and the bottom video playback device 8 is controlled.
While traveling between stations, the forward route video recorded in the forward route video reproduction device 3 is reproduced and displayed on the forward route video display means 4, and the blackbacks video is displayed on the side video display means 7 and the bottom video display means 10. Is displayed. When the traveling speed falls below the specified value, the video switchers 6 and 9 switch from the blackback video to the side video and the front lower video recorded in the side video playback device 23 and the lower video playback device 8, and the side video display means 7. And displayed on the lower surface image display means 10.
[0009]
At this time, the side image reproduction device 5 and the lower surface image reproduction device 8 always reproduce the side image and the front lower image, and the video switchers 6 and 9 switch between the blackback image, the side image, and the front lower image. Controls the display / non-display of the side image and the front bottom image.
Since it is necessary to synchronize the video with the front route video, the side video, and the front lower video, each time the train arrives at the specified synchronous section, store the synchronization signal at the same point in the same section of each video By synchronizing the front route image, the side surface image, and the front lower surface image, the shift between the images can be corrected.
[0010]
Next, the reproduction of the side image and the front lower image will be described with reference to FIG.
FIG. 2 is a graph showing a traveling state between the station where the railway vehicle driving training simulator according to Embodiment 1 of the present invention stops and the previous station.
In FIG. 2, the horizontal axis indicates the position of the train, and the right end is the stop position of the next station where it stops. The vertical axis represents the train speed, and the curve represents the state of deceleration when the vehicle stops at the next station.
While the train is traveling between the stations at a predetermined speed, only the forward route image is selected. When stopping at the next station, the train speed is decelerated so as to reach a predetermined speed before the next station where the train stops, so if the train speed falls below the preset speed regulation value V1, the driver The video switchers 6 and 9 switch the blackbacks video to the side video and the front bottom video, and the side video and the front bottom video are displayed on the side video display means 7 and the bottom video display means 10. Is done.
[0011]
According to the first embodiment, the side image and the front lower surface image when arriving at the stop station can see the same image as the actual stop, and the stop position is shown on the side surface and the lower surface. In addition, the driver can know the stop point accurately and can perform a fixed point stop training with high accuracy.
Furthermore, since the overlapping part of the front route image, the side image, and the front lower surface image is displayed in synchronization, the front route image, the side image and the front lower surface image can be seen as an integrated screen. Know exactly.
In addition, when the speed is faster than the set speed, the side image and the front lower surface image are not displayed, the blackback image is displayed, and the side image and the front lower surface image are displayed only when the speed is lower than the preset speed. Since it is configured, it is possible to see side images during driving and front bottom images when necessary, and it is possible to carry out highly accurate fixed point stop training.
