Abstract

PURPOSE:To broadcast arrival at appropriate time coping with open timing of the door of a train by performing a necessary arrival broadcast when an on-track signal indicating a train on the track of a platform and an open signal indicating the open door of a train are input. CONSTITUTION:When a train 1 is entered into the track circuit 3 of a previously decided platform 2, it is detected with an on-track detecting pat 4 and an on- track signal is output to a broadcasting control part 15. Meanwhile, in this condition, when the train 1 is stopped on the decided position against the platform 2 and a door 6 is opened, it is detected with a door opening detecting part 9 and an open signal is output to transmit with a transmitting part 10 on the train through an antenna 11 on the train. The open signal is received with a transmitting part 13 on the ground, output to a broadcasting control part 15. When inputting of the on-track signal and the open signal are detected with the broadcasting control part 15, immediately a broadcasting part 7 is started to perform necessary arrival broadcast.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a train arrival announcement device that automatically makes an arrival announcement when a train arrives at a station platform.

(Prior Art) FIG. 2 is a diagram showing a conventional example of a train arrival announcement device that automatically makes an arrival announcement when a train arrives at a station platform. This train arrival announcement device uses a track location detection unit 4 to notify that a train]- has entered a track circuit 3 of a predetermined station platform 2.
After a set time when the door 6 of the train 1 is expected to be opened, the broadcasting device 7 is activated to broadcast a predetermined arrival announcement. Incidentally, in FIG. 2, reference numeral 5 denotes a broadcast control section that counts this set time and controls the start-up of the broadcasting device 7.

(Problems to be Solved by the Invention) In the conventional device described above, the broadcasting device 7
Although the set time for the activation and up to the opening of door 6 is fixed, the time from detecting the presence of a train to opening of door 6 does not always match this set time, so in reality, the arrival announcement may be slightly different from the opening of door 6. It was done at the right time. For this reason, there has been a strong desire for improvements in order to realize arrival announcements that match the door opening timing.

The present invention has been made in view of the above, and an object of the present invention is to provide a train arrival announcement device that can broadcast train arrival announcements at appropriate timing.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above object, the present invention provides a track presence detection means that detects the presence of a train on a station platform and outputs a track presence signal, and a train door. The gist of the present invention is to include an open detecting means for detecting that a line has been opened and outputting an open signal, and a broadcasting means for performing a required arrival broadcast when a line presence signal and an open signal are input.

(Function) In the train arrival announcement device according to the present invention, the arrival announcement is made when the train location information and the opening signal are input, so that the announcement can be made in accordance with the opening timing of the train door.

(Example) Hereinafter, the present invention will be explained in detail using the drawings.

FIG. 1 is a diagram showing the configuration of a train arrival broadcasting device according to an embodiment of the present invention. In the figure, reference numeral 9 denotes a door open detection section that detects the opening of the door 6 of the train 1, and 10 indicates a vehicle having a function of transmitting and outputting the open detection by the door open detection section 9 as an open signal via the on-board antenna 11. This is an upper transmission section, and is installed in each train 1. Further, in FIG. 1, reference numeral 13 denotes a ground transmission unit that exchanges transmission information with the on-board transmission unit 10 via the ground antenna 12. The door opening detection section 9, on-board transmission section 10, on-board antenna 11, ground antenna 12, and ground transmission section 13 described above constitute a known ATO system 8 that automatically controls the operation of the train 1. It also constitutes an open detection means.

On the other hand, in FIG. 1, reference numeral 15 denotes a broadcast control section that receives a release signal from the terrestrial transmission section 13 and an on-line signal from the on-line detection section 4 and activates the broadcasting device 7. This broadcast control section 15 constitutes broadcasting means together with the broadcasting device 7.

In FIG. 1, the same parts as in FIG. 2 are given the same reference numerals, and detailed explanation thereof will be omitted.

Next, the operation of this embodiment will be explained.

When the train 1 enters the track circuit 3 of a predetermined station platform 2, the track presence detection section 4 detects this and outputs a track presence signal to the broadcast control section 15. On the other hand, in this state, when the train 1 or the station platform 2 stops at a fixed position and the door 6 is opened, the door open detection section 9 detects this and the on-board transmission section 10 transmits the on-board antenna 11. A release signal is transmitted and outputted through the terminal. When the terrestrial transmission section 13 receives this open signal via the terrestrial antenna 12, it outputs this open signal to the broadcast control section 15.

When the broadcast control unit 15 detects that the line presence signal and release signal have been input, it immediately activates the broadcasting device lf7 to perform the required arrival broadcast.

Therefore, according to the present embodiment, the arrival announcement can be reliably performed at a precise timing that coincides with the opening of the train door. In addition, by considering the train presence signal when starting the arrival announcement, it is possible to prevent a situation where the arrival announcement is made due to a malfunction when, for example, there is no train on the station platform. Furthermore, in the configuration of the train arrival broadcasting device of this embodiment, since a publicly known ATO system can be used, the complexity and size of the configuration can be suppressed.

In addition, in this embodiment described above, as shown in FIG.
By providing the timetable storage section 14 in the broadcast control section 15, information such as the departure time and destination of each train can be included in the arrival broadcast and broadcast.

In addition, in the embodiments described above, whether the open signal is transmitted via the transmission unit that constitutes the ATO system, or
The present invention is not limited to this, and transmission may be performed by allocating a part of the train radio frequency, for example.

[Effects of the Invention] As explained above, according to the present invention, the arrival announcement is made when there is train location information and the human power to signal the opening signal, so the arrival announcement is made at the appropriate timing corresponding to the opening timing of the train door. Arrival broadcasts can be made.
