Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a railway track monitoring / display system.
[0002]
[Prior art]
Conventionally, in order to monitor a railway line, an alarm is placed on a part of the railroad track, for example, a railroad crossing, to notify that a vehicle or a pedestrian has entered before passing the railcar, or to use a local mirror. It is placed so that railroad car drivers and pedestrians can check the surrounding situation.
[0003]
[Problems to be solved by the invention]
However, in such a system for monitoring a part of a railroad track, even if a person who encounters the location such as a driver of a railcar can grasp the situation, in the central control station of the railroad operator of the railroad track, , There is a problem that the detailed situation of the situation along the line cannot be grasped.
[0004]
By the way, as seen in the fire incident of the subway in Korea, if the central control station can accurately grasp the situation of the fire site, it will give proper instructions and countermeasures, and such many sacrifices It can't be said that we don't have to put out a person.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail.
[0012]
FIG. 1 is a schematic diagram of a railway track monitoring / display system showing an embodiment of the present invention, FIG. 2 is a configuration diagram of the central monitoring device, and FIG. 3 is a configuration diagram of the individual monitoring device.
[0013]
In these drawings, A is a central monitoring station and includes a central monitoring device 1. The central monitoring device 1 includes a transmission / reception device 2, a central control device 3, a storage device 4, a reference image storage device 5, a display device 6, a key input unit 7, and an alarm device 8. is doing. 9 indicates a station and 21 indicates a tunnel.
[0014]
On the other hand, the individual monitoring device 10 includes a transmission / reception device 11, a central control device 12, a storage device 13, a reference image storage device 14, an imaging camera 15, a video magnification / function changeover switch 16, and a function-enhanced fluoroscopic imaging camera 17. For example, it is fixedly arranged at the station premises, near iron bridges, overpasses, near power transmission lines, tunnel entrances, and the like. In addition, it is desirable to arrange | position the individual monitoring apparatus 10 so that it can monitor not only the location which needs to be monitored but all the lines along a railroad. Accordingly, the individual monitoring apparatus 10 is installed with an imaging camera that can see a considerable distance, for example, with a telephoto function added. As a result, it is possible to monitor all lines along the railroad and assist train operation while reducing costs.
[0015]
Therefore, normally, the individual monitoring device 10 is sequentially called by polling from the transmission / reception device 2 of the central monitoring device 1, and the nearby video captured by the imaging camera 15 of the individual monitoring device 10 is centrally transmitted from the individual monitoring device 10. Transmit to the monitoring device 1.
[0016]
Further, in some cases, if the polling is performed according to the progress of a railway vehicle (not shown), it is possible to monitor the railway line immediately before the operation, so that the accuracy of the safe operation can be improved.
[0017]
The transmitted image of the vicinity of the individual monitoring device 10 is displayed on the display device 6 of the central monitoring device 1. In that case, when the transmitted video is an abnormal video that is compared with a normal video stored in advance in the reference image storage device 5 and fluctuates from a predetermined value, the video is more closely watched by the supervisor. Display to (arouse).
[0018]
Specifically, for example, a blinking lamp is used together to urge the monitor to pay attention to the video. When the supervisor of the central monitoring device 1 recognizes that it is necessary to monitor the video combined with the blinking lamp in more detail, a command is transmitted from the central monitoring device 1 to the individual monitoring device 10, and the video magnification / The function changeover switch 16 is operated to change the magnification of an image in the vicinity thereof, or in some cases, the imaging camera 15 is switched to a function-enhanced fluoroscopic (night vision) imaging camera 17 that sees through darkness and smoke. It is possible to transmit a fluoroscopic image clarifying the above to the central monitoring apparatus 1.
[0019]
By configuring in this way, it is possible to reliably monitor the railway along the progress of the vehicle, and at the time of abnormalities along the railway, the central monitoring station accurately grasps the situation so that the driver of the vehicle The information and instructions can be provided in a timely manner, and it is possible to assist the driving of the vehicle driver in combination with signal devices at various locations along the line, and to perform safe operation in cooperation with the vehicle and the central monitoring station. it can.
[0020]
4A and 4B are diagrams showing a normal video and an abnormal video of the tunnel according to the present invention, FIG. 4A is a diagram showing a normal video of the tunnel, and FIG. 4B is an abnormal video in which the tunnel is partially collapsed. FIG.
[0021]
In FIG. 4, the inside of the tunnel 21 is monitored by the individual monitoring device 10 fixed at the entrance of the tunnel, and the normal image is transmitted as an image having no abnormality as shown in FIG. As shown in FIG. 4B, when an abnormal image in which a collapsed portion 22 is seen in a part of the tunnel is transmitted to the central monitoring device 1, the monitor at the central monitoring station A further details the situation. By confirming with a simple video, the operator of the railway car can be contacted, and the driver of the railway car can take measures such as slow driving the section. Furthermore, it is possible to carry out a close inspection by a staff member in the track maintenance area of the collapsed portion 22 of the tunnel.
[0022]
Further, instead of the above-described polling method, when the individual monitoring device 10 compares and contrasts the normal image stored in the reference image storage device 14 with the image of the imaging camera 15 and is an abnormal image exceeding a predetermined threshold value. Detects this, and automatically transmits an emergency alarm signal and an abnormal image from the transmission / reception device 11 of the individual monitoring device 10 and receives them at the central monitoring device 1, thereby displaying the central monitoring device 1. An abnormal image can be displayed on the device 6 and the alarm device 8 can be operated to alert the supervisor.
[0023]
For example, a method such as Japanese Patent Publication No. 5-73093 may be employed as a method for inserting emergency communication into communication using the polling method.
[0024]
In addition, this invention is not limited to the said Example, A various deformation | transformation is possible based on the meaning of this invention, and they are not excluded from the scope of the present invention.
[0025]
【The invention's effect】
As described above in detail, according to the present invention, the following effects can be obtained.
[0026]
(A) The video sent from the individual monitoring device can ensure that the central monitoring station can grasp the situation along the railway along with the progress of the vehicle. By providing the information and instructions to the vehicle, it is possible to assist safe driving. That is, the vehicle and the central monitoring station can cooperate to contribute to the safe operation of the railway vehicle.
[0027]
(B) According to a command from the central monitoring station, the individual monitoring device can transmit more detailed video information in the vicinity to the central monitoring station, and more reliable monitoring can be performed.
[0028]
(C) In the case of an emergency in which an individual video device captures an abnormal video, the alarm signal of the central monitoring device is activated automatically by sending an alarm signal to the central control device regardless of the polling method. Can be aroused.
[0029]
(D) Even if it does not go to the site, the abnormal part can be quickly identified, and it can be used for providing information, guidance, etc. to crew members and passengers.
[0030]
(E) The status of facilities along the railway can be understood and used as a reference for maintenance.
