【Example】

Example 1. FIG. 1 shows a basic configuration diagram relating to operation display in a train operation management system according to an embodiment of the present invention. Reference numeral 13 indicates the operation status displayed on the conventional operation display device 2 and the like according to the movement of the train. A video projector as a display device for displaying the ITV screen in a superimposed manner. If necessary depending on the length of the route to be displayed and the number of stations, two video projectors 1 and 2 are connected. An operation display controller 14 is connected to each video projector 13. The operation display controller 14 has a video composite NTSC and RGB input interface as a superimpose input, and can input an ITV camera 15 and a tuner 16 as well as a VCR, a laser disc, etc. (Frame / second) can be displayed on the X window. In addition, it has the function to save the frames of the moving image in the memory at arbitrary intervals and display them for playback later.

Normally, the video projector 13 displays an operation status screen (computer screen) which is RGB input from the operation display controller 14 (engineering workstation). On the operation status screen, the wiring diagram that is the shape of the track, platform, station name, train number display window on the platform and between stations, etc. are displayed, and the train number in the train number display window corresponds to the movement of the train. Color change (non-existence line; blue, route configuration; yellow, presence line; red) due to shift and train presence on the wiring schematic is performed. When the ITV screen is displayed in a superimposed manner according to the movement of the train, the window is cut and displayed at predetermined coordinates on the operation status screen. FIG. 2 shows an example of a video projector display screen. In this example, since the train entered the approaching section of B station, the color change of the route etc. due to it and the IT at B station
The V screen is displayed in superimpose.

Next, the flow of processing of the operation display controller 14 will be described with reference to the flowchart of FIG. Normally, the operation display controller 14 obtains station display information (positions of trains, traffic lights, route status, etc.) from the relay section of the station via a transmission device, and adds a train number unique to the train to a video projector. The operation status screen, which is a computer screen, is displayed as the base screen 13 (S1). If the train is in the approaching section of the station (usually the third track circuit outside the on-site traffic signal) due to changes in the position of the train (track circuit drop) (when there is S2), install on the platform of that station ITV camera 15
A video image of the congestion of the home captured by is displayed near the display of the station by superimposing (S3).
When no train has entered the approaching section of the station (when there is nothing in S2), only the operation status screen is displayed. Similarly, when the train departs from a station and enters the first track circuit on the inner side of the departure signal (when there is S4), the ITV screen of the station already displayed is erased (S).
5). As a result, only the operation status screen is displayed on the video projector 13 (S1). Further, when the operation commander requests information from the tuner 16 using a keyboard or the like (when YES in S6), the tuner screen is displayed in a superimposed manner (S7). The information from the tuner 16 includes weather information, news, etc., which have a great influence on train operation.

Similarly, when the tuner screen is erased from the keyboard or the like (if yes in S8), the tuner screen already displayed is erased (S9). As a result, only the operation status screen is displayed on the video projector 13 (S1). The frames of the moving image are stored in the memory at arbitrary intervals at each time, and when the playback is input by designating the time in order to verify the disorder of the timetable, the weather abnormality, etc. The time frame is played back and displayed (S11). Further, when a hard copy is requested (when it is present in S12), the hard copy can be output. When the deletion of the playback display is input (Yes in S13), the playback display is deleted and only the operation status screen which is the base screen is displayed (S1). Incidentally, the above S4, S6, S8, S10, S1
If the result of 2 and S13 is "NO", there is no change in the screen displayed at that time. As described above, the ITV screen is automatically displayed on the operation status screen in a superimposed manner depending on the position of the train.
Not only can the ITV screen be checked without it, but the operation of switching the ITV screen by the commander becomes unnecessary.

Embodiment 2 FIG. Although the computer screen and the ITV screen or the tuner screen are combined by the superimpose input interface of the operation display controller in the first embodiment, the operation display controller does not have the superimpose input and the external display is performed as shown in FIG. May be provided with a multimedia scan converter. The multimedia scan converter is a synthesizing device for displaying a video of a video camera, VTR, or ITV on a display of a workstation in real time by cutting a window. This multimedia scan converter uses the RGB input from the operation display controller 14 as a base signal and the NTS from the ITV camera 15 and the tuner 16.
The C inputs are combined and RGB output is performed to the video projector 13. As described above, as in the first embodiment, the ITV screen and the tuner screen are automatically displayed on the computer screen of the operation display controller 14 in the video projector 13 in superimposition in accordance with the movement of the train.

Example 3. Depending on the environment where the equipment is installed, the cables between the equipment may be long, which may adversely affect the image quality. However, assuming that case, the distributor with cable compensator is added to the basic configuration of Embodiments 1 and 2 above. May be provided. The distributor with a compensator distributes the output signal of one device to a plurality of devices while preventing the signal level from being attenuated. The block diagram is shown in FIG. This not only eliminates the problem of signal attenuation, but also enhances the expandability of each terminal such as display on another display or hard copy. For example, even if the ITV screen is conventionally switched in a maintenance terminal room or the like that is distant from the operation command room, the ITV screen is automatically switched according to the movement of the train.

Example 4. Further, in the above-described first to third embodiments, although the video projector is used as the operation display device, the operation display controller C which is an engineering workstation is used instead of the video projector.
The RT may be the main display device. In this case, the ITV screen or the like may be displayed in the superimposed manner as in the above embodiment, but when the display screen is too small to be seen well, the entire screen is changed from the operation status screen to the ITV screen instead of the superimposed display. It may be switched. This eliminates the need for a video projector and makes the device cheaper.

Example 5. Further, in the above-mentioned first to third embodiments, the ITV screen is synthesized on the computer screen by superimposing, but with this configuration, several ITV monitor CRTs are installed on the video projector and the superimposing of a certain station is performed. If the pause ITV screen is enlarged and displayed on the ITV monitor CRT, the details of the ITV screen can be confirmed. In this case, it is advisable to display the superimposed display on the video projector at the same timing as in the first embodiment and display it on the ITV monitor CRT at a certain fixed cycle. As a result, the ITV monitor CRT, which has conventionally required 20 or more units, can be saved to a few, and the operation management work can be efficiently performed.

[0028]

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

Since the operation display controller automatically switches the ITV screen according to the movement of the train, the operation management work can be performed efficiently.

Further, since the switched ITV screen is displayed on a part of the operation status screen of the video projector by superimposing, the ITV monitor CRT is unnecessary and the apparatus can be inexpensive.

Since the ITV screen is displayed in a superimposed manner by the multimedia scan converter, the ITV screen can be switched more easily.

Since the distributor with the cable compensator is provided, the expandability of the system is enhanced.

Further, since the CRT of the operation display controller is used as the display device, the device can be made cheaper.

Further, since the output to the ITV monitor CRT is performed together with the superimposed display of the ITV screen, more detailed operation management work becomes possible.

Further, the operation display controller displays the ITV screen imaged by the ITV camera at the station from the moment the train is in the approaching section of the station to the time when it enters the first track circuit inside the departure signal of the station. Is displayed on the display device, the operation status can be easily grasped.
