The CPU 5 performs a prescribed processing by ADPCM data and memory data of the ROM, operates a speach synthesis part 10, and performs an annonucement in the train.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a speech synthesis guidance broadcasting system for trains that automatically broadcasts guidance using speech synthesis within a train in accordance with the operating conditions of the train.

[Prior Art] Conventionally, this type of train guidance broadcasting device broadcasts various train information, service information for passengers, etc., depending on the status of the train traveling from the starting station to the terminal station.

In such conventional technology, each time the train completes traveling to a predetermined position, the conductor operates a command device installed in the driver's cab.

Then, the tape recorder that had previously recorded the broadcast content was activated, and the necessary broadcast content information was broadcast to the passengers from a plurality of speakers installed at predetermined locations in the train.

In addition, with conventional technology, the train's progress is automatically detected without the conductor having to operate the command unit every time the train is operating, and the tape recorder that records the broadcast content in advance automatically detects the progress of the train. It was configured to start operating and broadcast various necessary train information through speakers.

Incidentally, a conventional passenger guide device of this kind for a vehicle is disclosed in Japanese Patent Application Laid-open No. 128495/1983.

[Problems to be Solved by the Invention] Since the conventional technology has the configuration described above, the following problems have emerged.

■ It was cumbersome for the conductor to operate the command unit one by one depending on the train operating status.

(2) Since the guidance broadcasting device is equipped with a tape on which broadcast contents are recorded in advance, the recording capacity of the tape is limited, and the tape may deteriorate after many years of use.

Therefore, quality problems arose.

■ If train routes are changed, station names are added or modified, or train information increases or changes, it is necessary to replace the tapes, which increases the number of man-hours required for replacement and requires preparing a large number of tapes in advance. was necessary and not economical.

The purpose of the voice synthesis guide broadcasting device for trains according to the present invention is to eliminate the drawbacks of the conventional techniques described above.

[Means for Solving the Problems] The present invention aims to solve the problems existing in the conventional technology, and employs the following configuration and means. That is, by inserting a serial data receiving section that receives and decodes train number and distance data, a CPU that processes signals from the serial data receiving section, and a card that stores phrase combinations depending on the train, an ADPCM decoder can be installed. The present invention also provides a speech synthesis guide broadcasting system for trains, which is comprised of a speech synthesis section that generates speech via a digital-to-analog converter, and a display section that displays whether the operation is normal or abnormal.

[Function] Since the present invention employs the configuration and means as described above, for example, a card storing various service information during train operation and phrase combinations corresponding to the train can be inserted into the card insertion hole. Therefore, depending on the train's operating status, the second stop is Osaka Station. This is to synthesize and output the information of j.

The system also has the feature that the driver does not need to operate the command unit every time the train operates, and the necessary voice synthesis information is automatically sent to the train cabin.

In addition, even if there is a change or addition to a train's operating route or addition or change to a stop station name, there is no need to change the card that stores phrase combinations according to the train. play an action.
