Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic broadcast system for in-train announcements.

There are two conventional in-vehicle broadcasting methods: one method has a sound source on the ground and transmits the sound to the vehicle, and the other has a sound source on the vehicle and broadcasts the sound inside the vehicle.

In the former case, train information is stored in a storage device 2 as shown in FIG. 1, and is transmitted from the processing device 1 to the train via the communication control device 3 and communication cable 13 at necessary timing. Communication control device 4 on the vehicle
A voice signal is synthesized through the voice synthesis logic device 6 and broadcasted in the car as a broadcast text by the broadcasting device 7 and the car speaker 8. In this broadcasting system, it is easy to correct or change information, it has flexibility, and it has excellent maintainability because it can be inspected all at once on the ground.

However, the required capacity of the storage device 2 increases,
In order to lay the communication cable 13 along the track,
The communication control device also has a large capacity and is expensive.

For the latter case, which is broadcast in the car using an on-board sound source, the sentence to be broadcast is stored in the on-board storage device 5 as shown in FIG. The signals are synthesized and broadcast in the car using the broadcasting device 7 and in-car speaker 8. In this case, as the storage device 5, for example, a one-man bus cassette tape or the like can be used, which is inexpensive, but since all the devices are on the vehicle,
There is no flexibility and there are difficulties in maintainability.

As described above, it has conventionally been difficult to obtain an in-vehicle automatic announcement system that is flexible, has a small capacity, and is easy to maintain.

The present invention provides flexibility and small capacity for in-train broadcasting by combining train ground information and preset on-board phrases.
The purpose of the present invention is to provide an in-train public address system that is easy to maintain.

In order to achieve the above object, the present invention places sound sources both on the ground and on the train, with the sound source on the train having a fixed phrase, and the sound source on the ground changing depending on the time, train, and train position. be.

By combining these two sound sources and broadcasting as a complete sentence, both the on-board equipment and the ground equipment can be relatively simple and require only a small capacity. There is also plenty of flexibility, as ground equipment can transmit information that varies depending on the time, train, and train location. Therefore, flexibility and maintainability, which are conventional problems, and small capacity and low cost can be achieved at the same time.

Hereinafter, the present invention will be explained in detail with reference to Examples.

The present invention stores certain broadcast phrases in advance in the on-board device, and provides information that changes depending on the time, train, and train location, such as destination, departure time, next stop station, direction of exit, and transfer information. Information such as guidance is transmitted from the storage device on the ground to the vehicle.

Once received onboard, the information is memorized, and a preset onboard phrase is combined with this ground information to be automatically broadcast as a complete sentence to the inside of the vehicle. For example, as shown in FIG. 3, on-board phrases are stored in the on-board storage device 5, train information is stored in the storage device 2 through the processing device 1 on the ground, and
If necessary, it is transmitted as an analog signal or a digital signal to the communication control device 4 on the vehicle through the communication control device 3 on the ground. After the ground information received in step 4 is temporarily stored in the storage device 5, it is combined with onboard phrases and synthesized in the speech synthesis logic device 6, and then broadcast at the necessary timing according to train information or broadcast commands from other systems. It is automatically broadcast to the inside of the car through the device 7 and the in-car speaker 8.

FIG. 4 shows a specific example of the combination of on-board phrases and ground information according to the present invention. in this case,
Each track on the magnetic disk is divided into necessary sectors, and each track stores on-vehicle phrases and ground information. For example, track number 01 in Figure 4a
and the first sector, track number 21 and the second sector, and track number 02 and the third sector, the onboard phrase and ground information are combined in the order of, as shown in the sentence example (1) in Figure 4b. It becomes a complete sentence. If track number 03 and the first sector, track number 21 and the second sector, and track number 04 and the third sector are selected in the same way, a complete sentence like sentence example (2) in FIG. 4b will be obtained. If this is broadcast in the car using the speaker 8 shown in FIG. 3, it can be broadcast accurately without errors. Also,
As in this example, the on-vehicle phrase is track number 01.
The required number of tracks, for example, 20, can be taken from the above, and the more tracks than that can be used as addresses for ground information.

Next, an embodiment of the communication method according to the present invention is shown in FIG. In FIG. 5, reference numeral 9 indicates a train track, 10 indicates a train, and 11 and 12 indicate communication devices on the ground. In the present invention, by having a storage device on the ground and on the vehicle, communication between the ground and the vehicle is possible because the time required to transmit information from the ground to the vehicle is extremely short. It is only necessary to transmit information from the ground up to the communication interval in a short time. Therefore, ground information is transmitted from the communication device 11 in FIG. The above communication is performed between communication devices 12 and 10.
In this way, communication is possible with a small capacity communication system.
