Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a train operation platform monitoring system in which the condition of each station platform used by passengers is photographed by a TV camera and monitored by a monitor or television.

[Prior art and problems]

When a train is in operation, the condition of the platform is photographed with a TV camera and monitored on a monitor or television. In this case, the conductor or station staff of the 19 train usually confirms the safety of the passengers on this monitor/TV and signals the driver to depart.

By the way, in recent years, in order to save labor, unmanned stations have been introduced in subways and other places where trains are operated by single drivers. In such a case, monitors and televisions will be placed at the traffic control center and monitors will be able to view them all at once.

By the way, if we install two monitors/TVs each at the top and bottom of the station, and two at Baum, each station would require four monitors/TVs, and if there were 10 stations, we would need 40 monitors/TVs. Concentrating traffic in a traffic control center requires a large amount of space and a large number of observers. For this reason, there is a need to reduce the number of monitors/TVs to efficiently monitor the status of each station during each train operation.

[Purpose of the invention]

The purpose of the present invention is to meet such requirements,
To this end, it is an object of the present invention to provide a train operation platform monitoring system capable of monitoring the status of each station with a small number of monitors and televisions by monitoring one train in operation using one set of monitors and televisions.

[Structure of the invention]

In order to achieve this object, 1. In the train operation platform monitoring system of the present invention, the boarding/disembarkation status of passengers for trains and the status of passengers on the platform are monitored on a television. A plurality of CTCs, a plurality of television receivers corresponding to at least the number of trains in operation, and a television camera installed on the platform;
It is equipped with a video switching device that switches and controls video signals for these television receivers, and identifies the television receiver that monitors trains in operation at the time of monitoring.
A feature of this system is that this monitoring is performed while the train in operation is stopped at the platform.

[Embodiments of the invention]

Before describing one embodiment of the present invention in detail, its outline will be explained.

In the present invention, for example, a traffic control center is provided with as many monitors and televisions as there are trains in operation, and the monitors and televisions are specified for each train. The system then monitors the condition of the train until it departs after it enters the station.

In this way, the number of monitors and TVs will only be required depending on the number of trains in operation, which is about 100% compared to the conventional case where the number of monitors and TVs needed depends on the number of station platforms. Only half the number is required.

An embodiment of the present invention will be described based on FIGS. 1 and 2. FIG.

1. rgJ is a block diagram of an embodiment of the present invention, and FIG. 2 shows a display state of a monitor television set.

As shown in Figure 2, the monitor/TV M placed in the traffic control center consists of a receiver 11TV and a display.On the display 1, the train number received on the TV receiver is displayed. The name of the station where the train is stopping will be displayed on the TV screen.

The name of the station where the train that the monitor should monitor is stopping.

You can monitor the status of that station. In this case, the number of monitors/TVs can be selected as appropriate, such as 9, for example, 2 or 3 per station, but in FIG. 1, the case of 1 monitor is described for the sake of simplicity.

In FIG. 1, 10 is a traffic management device.

A large number of CTC+ -CTCMs (
Train operation information 1 (e.g., train number, station name) output from the Central Train Control (Central Train Control).

It provides comprehensive management of how each train is currently being operated in terms of up/down lines, incoming/outgoing lines, speed, etc.

The monitor control unit 11 receives data such as where each train is currently operating and in what condition based on the information transmitted from the CTC+ to CTCM.

A video switching device 12 was installed at each station. The image signal sent from the TV camera is received for monitoring taTV-
1 to TV-M. In this case, the station has television cameras installed on both the up and down platforms.

The video control section 13 outputs a switching control signal to the video switching device 12 based on the data sent from the monitor control section 11, and also sends a stop station name signal for each train to the station name display control section 14.

The station name display control unit 14 displays a monitor image 1i”rv-1.
~ This is to control station name display on TV-M.

The operating train number extracting unit 15 recognizes the number of the train in operation from the signal transmitted from the monitor control unit 11, and determines the monitor receiver in advance according to the operating status of the train. A table (not shown) is used to determine which train information is to be displayed on which monitor receiver.

The train number display control section 16 controls the display of train numbers on the displays mD-'1 to DM.

In FIG. 1, 11k1.1 to Nam are trains.

Trains (Il & 12) stop at the inbound platform of C station (entering the train)
This shows a case where three trains (Nh3.Nam) stop at the downbound platforms of A and N stations, and one train (No. 1) is operating on the upbound line between A and B stations.

The operation information of each of these trains is transmitted to the operation management device 10 from CTCl-CTCM. and operation control device lO
Based on the train operation information from these CTC+-CTCMs, the traffic management center constantly monitors where each train is currently located and in what condition it is operating. This operation management device 10 includes a monitor control section 11
Against.

Outputs where each train is currently operating.

The monitor control unit 11 sends one train number information to the operating train number extraction unit 15, and the operating train number extraction unit 15 thereby refers to a monitor receiver selection table (not shown) and selects a monitor receiver for each train. video control unit 1.
3 and the train number display control section 16. Based on this, the train number display control unit 16 displays the instructed display, device D.
Selectively display train numbers from -1 to DM.

The video control section 13 recognizes the television receivers TV-1 to TV-M to be displayed in correspondence with the train number based on the monitor receiver selection information transmitted from the operating train number extraction section 15. Then, from the monitor control unit 11, the name of the station where the train entered the line, the upstream, and the downward P
When the line and train number information is transmitted, the video switching device 12 is controlled accordingly, and the image signal of the TV camera installed on the predetermined platform of the station where the line is entered is transmitted to the receiver corresponding to the train number. control so that it is input to At this time, the station name display control unit 14 sends the name of the station on the line to the receiver, and this station name is displayed on the receiver along with the status of the platform.

This allows the monitor to be closer to the screen of this receiver.

Since you can see the platform status from arrival to departure, you can check the safety status of passengers at that station, and if there is an abnormality, this will be communicated to the train driver, and depending on the situation, the train will be able to control the departure and stop of the train. .

By doing this, at intervals of three and a half minutes.

Experimental results showed that when a train runs through 10 stations (20 up and down platforms), it can be monitored using about 10 sets of monitor receivers, half the number of conventional systems.

〔Effect of the invention〕

According to the present invention, since the train in operation is configured to be monitored by a monitor receiver when it enters the station, monitoring can be performed more efficiently with a smaller number of receivers than when monitoring at each station. can do. In addition, the monitor and train are in a corresponding relationship, and the status of each station is displayed sequentially as the train progresses.

From an operational standpoint, it does not cause any discomfort to the observer.
