Abstract

PROBLEM TO BE SOLVED: To realize a monitor image switching system capable of quickly and reliably performing station platform monitoring in a driving command office. SOLUTION: A CTC device 7, a train radio device 6, and an image selector 3 are connected to a calculator 1. The calculator 1 detects the position and the state of a train on the basis of the train information and various signal facility information obtained from the CTC device 7 and the train radio device 6, and automatically switch-controls an image of a monitor device 2 by editing and outputting information of the station to be monitored, the camera number and the monitor number on which the image is to be displayed in relation to the image selector 3 with the movement of a train when monitoring is necessary in the operation command office. A commander can quickly and reliably perform monitoring of the platform only by monitoring the image of the monitor device 2, to be automatically displayed by the calculator, and therefore, the load of the commander can be decreased.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video switching system for a monitor installed in a driving command center.

[0002]

2. Description of the Related Art In recent years, there has been an increase in one-person crew operation in which a train driver uses a monitor device provided in a driver's seat or the like to open and close a train door and monitor the platform when leaving a train. In this case, when there is a failure in the driver's seat monitor device or a failure in the train image transmission facility for transmitting images to the train, the driver will not be able to perform these tasks, so the dispatcher at the operation command center Performs these tasks using a monitor installed at the command center, and supports trains with one-person crew operation.

However, in the conventional configuration, in the monitor device installed at the operation commanding place, the cameras of each station are often fixedly assigned to each monitor device as in the example shown in FIG. If a failure like
The dispatcher had to constantly monitor the operation status of the train and select a monitor device for displaying the next station platform to arrive at for monitoring. This is a heavy burden on the work for the dispatcher who manages the operation of many trains, and when multiple trains must be monitored,
There was a risk of oversight and there was a safety issue.

[0004]

SUMMARY OF THE INVENTION The present invention realizes a monitor image switching system capable of quickly and reliably performing home monitoring work at a driving command place without complicated work, and reduces the burden on a dispatcher. belongs to.

[0005]

In order to achieve the above-mentioned object, the present invention has a constitution in which a computer is connected with a CTC device, a train radio device, a video switching device and the like. The computer detects the train status and position from the train information and various signal equipment information obtained from the CTC device, train radio device, etc., and when platform monitoring is required at the operation command center, the video at each station of the moving train Are automatically displayed on the same monitor device. At this time, the alarm buzzer sounds and the alarm lamp installed on the monitor is also turned on.

[0006]

According to the present invention, since the computer automatically switches the images on the monitor device as the train moves, the commander always monitors the same monitor device, and the complicated work as in the conventional case is required. It is possible to quickly and surely monitor the home without carrying out, and it is possible to reduce the burden on the dispatcher.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows the configuration of a monitor video switching system which is an embodiment of the present invention. This system is a train radio that mainly collects various train information obtained by radio from a computer 1, a monitor device 2, an image switching device 3, an alarm lamp 4, an alarm buzzer 5, and a train installed at a driving command station as data. Device 6, Train operation status, control various signal equipment status,
It is composed of a CTC device 7 to be managed, a console 16 and the like.

The computer 1 fetches information about a failure of the monitor device 14 on the train from each related equipment such as the train radio device 6 and the CTC device 7 and data about a failure of the light transmitter 11 for transmitting an image to the train. When the station platform monitoring work is required at the central operation command center, the video switching device 3
Edits and outputs information such as the station to monitor, the camera number, and the monitor number that displays the video. Thereby, the video switching device 3 outputs the designated camera video and station name to the monitor device 2. At this time, the computer 1 uses the alarm buzzer 5
Together with the lighting control of the alarm lamp 4 installed on the upper part of the monitor device, and informs the commander of the timing of home monitoring and which monitor device to look at. The computer then CTs the location of the failed train.
It detects based on the track circuit information obtained from the C device 7, and automatically switches the same monitor image as that previously displayed at the timing when the train enters each station platform. This process is performed until the failure is recovered or the vehicle is loaded into the garage.

As a result, the instructor can always monitor the same monitor device to quickly and surely monitor the home without performing the complicated work as in the conventional case.
This has the effect of reducing the burden on the dispatcher.

[0010]

As described above, according to the present invention, when it is necessary to perform home monitoring work at a driving command place,
Since the computer automatically switches the image on the monitor device as the train moves, the commander can always monitor the image on the same monitor device to enable quick and reliable home monitoring. In addition, this system can be used for monitoring the platform when an accident occurs on the station yard or when the train schedule is disturbed, so it is effective even when not driving alone.
