Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention provides train tracking based on solid equipment that controls and monitors routes and distributed at each station, and based on service schedule information and equipment information at each station sent from the solid equipment. The present invention relates to a distributed traffic control system in which station equipment for route control and primitive guidance is connected via a transmission line, and in particular to a central monitor of the output of a sound source device for release, which is connected as a terminal of the station control equipment.

[Background of the invention]

For example, in the conventional distributed operation management system as shown in Japanese Patent Application Laid-open No. 53-65004, if there is an abnormality in the broadcast content at each station, the operator has no choice but to rely on communication from station staff from the station. It was inconvenient to manage the content of passenger information broadcasts, which is important for management.

[Purpose of the invention]

An object of the present invention is to enable a station control device to input broadcast content from a sound source device for passenger guidance broadcasting at each station terminal as input information using a transmission line that exchanges information between the central station and the station.
The aim is to centrally manage the contents of passenger information broadcasts at each station by centrally monitoring them.

[Summary of the invention]

The distributed operation management system of the present invention includes a solid device that centrally manages the operation status of all lines, a station control device that is distributed at each station and performs train operation control and passenger guidance control within the range of each station, and this station control device. It consists of a sound source device that is connected as a terminal device, and a transmission line that connects these devices.

At each station, departure order information and train information for each station are given to each station device as planned timetable information before the day's train service begins by a solid device. The station control device takes in equipment information (track circuit information, signal, switch information, etc.) within the vending area and tracks trains within the vending area, and also uses the departure order information of the planned timetable and the train location status. As self-sold passenger information broadcasts, applicable number information, approach broadcasts, arrival broadcasts,
Broadcast type information such as transfer guide broadcast and departure broadcast is given to the sound source device. The sound source device analyzes this information and outputs the broadcast text to the platform of the corresponding number via the broadcast amplification device.

With this configuration, the sound source device encodes the content being broadcast and outputs it digitally, and the station control device receives this output as input and sends it to the solid device via the transmission line, and the central system broadcasts the broadcast for each station line number. Monitor content.

With this configuration, you can create a station control system! ! ! 2 and the sound source device 13 are connected by a serial transmission circuit due to the large amount of data per unit time and to simplify the connection, and data is sent from the station control device 12 to the sound source device 1t13. The sound source device 13 receives the broadcast type code (broadcast type signal such as track and approach, arrival, departure, etc.) sent from the station control device 2, synthesizes the broadcast text, outputs an audio signal, and outputs an audio signal to an external broadcasting add-on. It is output to the iJ device 14. In addition, when the broadcast type code is no longer sent from the station control device 13 side (transmission failure), the sound source device sends a simple approach broadcast to inform customers on the platform that there is an approaching train as minimum information. Are the digital input circuit for taking in the orbit information necessary for performing this from the relay movement device 6 and the sound source device 13 in this simple broadcasting state?

Alternatively, it has a digital output circuit that controls the lamp 28 that informs the station staff that it is in a normal state.
