Abstract

PROBLEM TO BE SOLVED: To easily edit and modify broadcast contents without an error by providing a control part with a storage means which reads in management information from one external memory where management information and sound source information of broadcast contents are recorded through an interface and allowing the control part to generate a broadcasting command by the management information read in the storage means and a separately stored broadcast program. SOLUTION: The control part 10 fetches the switch signal of a forward/ backward switch 3 for the travel direction of a train, the opening/closing signal of a door opening and closing device 4, and the output signal of a pulse converter 5a for converting the output of a speed signal generator 5 into the travel distance of the train through an I/O 11. Further, management information of broadcast contents are read in from an IC memory card 2 through a reproduction part 20 and an I/O 12 and stored in a RAM 14. Consequently, a CPU 15 generates a broadcasting command. The reproduction part 20 reads in sound source information of the broadcast contents from the IC memory card 2 and uses the sound source information according to the command from the control part 10 to generate an analog voice signal through voice synthesis.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An automatic broadcasting apparatus according to the present invention will be described below with reference to an embodiment shown in the drawings. FIG. 1 is a diagram showing a schematic configuration of a broadcasting system in a train using the automatic broadcasting device of the present invention.

In FIG. 1, reference numeral 1 denotes an automatic broadcasting device main body,
The apparatus main body 1 includes a digital input unit (I / O) 11, 1
2, a ROM 13 for storing (storing) a broadcast program and a control program, a RAM 14 for storing (storing) broadcast content management information, a CPU 15 for creating a broadcast command, and a control unit 10 surrounded by a dotted line including a clock unit (clock) 16.
And an audio reproduction unit 20 and a connection unit 30 for the IC memory card 2 as an external memory.

The control unit 10 receives, via a digital input unit 11, a switching signal of the front / rear switch 3 for setting the traveling direction of the train, an opening / closing signal of the door opening / closing device 4, and an output of the speed generator 5, for the travel distance of the train. The output signal of the pulse converter 5a for conversion into is taken in. Further, it reads management information of the broadcast content from the IC memory card 2 via the playback unit 20 and the digital input unit 12 and stores it in the RAM 14. The type of broadcast is set by the driver or conductor from the keyboard 7 by looking at the content displayed on the monitor 6.

Although a detailed illustration of the reproducing unit 20 is omitted,
It has a dual port RAM, a RAM and a speech synthesizer,
Reads management information of broadcast contents from the C memory card 2 and
In addition to the transmission to the AM 14, the sound source information of the broadcast content is read from the IC memory card 2 and stored in its own RAM, and voice synthesis is performed using the sound source information stored in the RAM in accordance with a command from the control unit 10. Generate analog audio signals. Reference numeral 8 denotes an amplifier for the audio signal sent from the reproduction unit 20, and 9a and 9b to 9n denote speakers in the train.

Next, management information and sound source information of broadcast contents stored in the IC memory card 2 will be described. FIG.
4 to 4 are management information data tables, and FIG. 5 is a sound source information data table.

FIG. 2 is a train number (vehicle number) information table listing the starting station, the ending station, and the stop station pattern between the train stations in each train number. FIG. 3 is a stop station pattern table for defining the stop station broadcast guide (stop next station guide) and arrival guide time of the stop station pattern in each item number of FIG. 2 by distance, and FIG. 4 is each station code of FIG. FIG. 5 is a sound source data table for each sentence number in FIG.

The stop station pattern in FIG. 2 differs from the stop station pattern depending on whether the train is a regular train, stops at each station, is a high speed train, or is a special express train. Each stop station of the train can be checked. The stop code corresponding to the train number can be selected by displaying it on the monitor 6 in FIG. 1 and selecting a pattern code using the keyboard 7. I have.

For each of the pattern codes A to X in FIG.
As shown in FIG. 3, the point at which broadcasting is performed during traveling from the first station to the last station is defined by the distance from the start of each station. Then, station codes A1 to An to X1 to Xn are assigned to each station. These station codes A1 to An to X
There is a broadcast content table shown in FIG. 4 in association with 1 to Xn. For example, what kind of guidance is to be provided in the next station guide, and the number of sentences and a sentence number corresponding to the number of sentences are assigned. The content of each sentence number is set in the sound source data table of FIG.

Therefore, the management information shown in FIGS. 2 to 4 and the sound source information shown in FIG. 5 can be displayed on a monitor, and the data can be freely set or changed using a keyboard while comparing the data.

Next, the actual automatic broadcasting will be described with reference to the flow charts of FIGS. As shown in FIG. 6, at the starting station, first, a step (hereinafter, abbreviated as “S”) is performed.
Car number setting of 10 is performed. At the start of operation, the driver or conductor knows the train number (vehicle number), destination, stop station, etc. of the train to be driven, so the monitor 6 in the driver's seat displays the train number information table shown in FIG. The corresponding pattern code, for example, the pattern code A in FIG. 2 is selected. Then, the control unit 10 stores management information (data of the station codes A1 to An) of the broadcast contents stored in the IC memory card 2 such as the stop station pattern table shown in FIG.
Then, the sound source information (data of the sentence numbers 101 to 101 related to the station codes A1 to An) in the sound source data table of FIG.

When the reading of the data is completed, the process proceeds to S20, where the destination of the train is guided while the vehicle is stopped. At this time, since the train is stopped at the starting station, the station code A1 in FIG. 3 is selected by the control unit 10, and the number of sentences and the sentence number of the station code A1 in FIG. 4 are transmitted to the reproduction unit 20 as a broadcast command. Is done.

The reproducing section 20 performs a table search in S61 based on a command from the control section 10 as shown in FIG. 7, and determines in S62 whether there is corresponding data. If not, the process ends as not applicable. However, if there is, the process proceeds to S63, and since the number of sentences is 3 in the station code A1 in FIG. 4, 3 is written into the RAM of the reproducing unit as the number of sentences. Next, in S64, it is determined whether or not the number of sentences is 0. If the number of sentences is 0, the process ends. However, it should be 3 at this point. Therefore, the process proceeds to S65, where the document number is written in the RAM of the reproducing unit. Subsequently, in step S66, the audio data is searched to determine whether there is any corresponding data. At this point, since the data has not been broadcast and there is data, the flow advances to S68 to reproduce the sound of one sentence of the sentence 101 in FIG.
Thereafter, in S69, the number of sentences is decremented to reduce the number of sentences to two.
And returns to S64.

In this way, automatic broadcasting is performed one sentence at a time, and the process ends when the number of sentences has reached zero.

When the destination guidance is completed, a flag is set in the broadcast completion column in FIG. 4, and it is determined in S30 in FIG. 6 whether the door is open. If the vehicle is stopped, the determination of S30 is repeated, and when the door is closed, the process proceeds to S40 and the traveling distance is counted. This is performed based on an input from the speed generator 5. Then, the process proceeds to S50, and it is determined whether or not a point at which the guidance of the next station is to be performed has been reached. If not, the process proceeds to S70. Since the arrival guidance is given at a further point,
Proceed to S90. Since the door is closed during running, S40
Return to While this is being repeated, when the vehicle arrives at the next station guide point, the process proceeds to S60 and guides the next station. Since this broadcast is performed in the same manner as in FIG. 7 based on the station code A2, the description is omitted.

Since the train is proceeding during the broadcast, the next station guidance is not performed again even if the process returns to S40 after the broadcast is completed. When the broadcast is completed, a flag is set in the broadcast completion column of FIG. Can be If it is determined in S70 that it is an arrival guidance point, an arrival broadcast is performed in S80. A flag is similarly set at the end of the broadcast. The door is closed. That is, if the vehicle is running, S30 to S90 are repeated,
When the vehicle arrives at the next station, the door is opened, so the process proceeds to S100 and resets the distance count in preparation for the next S40. Thereafter, in S110, the station code is set to A3. The process further proceeds to S120, and it is determined whether or not the vehicle has arrived at the terminal station. This determination is made based on whether the station code is An, or whether a flag is set in the broadcast completion column of the station code An in FIG.

If the vehicle has not arrived at the terminal station, the process returns to S30, and the above processing is repeated to sequentially guide the next station and the arrival at the appropriate points after departure or before arrival, respectively.
End processing is performed when the terminal station is reached. This is the control unit 1
0 of the management information stored in the RAM 14 of the
The sound source information stored in M and the flag in the broadcast completion column in FIG. This end processing is not performed, and the next vehicle number setting processing S10
In, when data is read, overwriting can be performed.

In the above embodiment, the train number information table shown in FIG. 2 is displayed on the monitor to select a pattern code. However, since this table is specific to the train, the monitor 6 is not provided. A hard copy of this table may be prepared in the driver's seat, and the item number or pattern code may be manually input from a keyboard or operation panel.

As described above, since the management information and the sound source information for broadcasting are stored in the same single memory, when editing or when a change is required, the table of both information is stored in the personal computer. It can be displayed on the screen at the same time and edited while comparing.

Further, by providing a train number information table as management information, even if the same train corresponds to various running patterns, one memory is sufficient and the same train may be caused by a mistake in the memory. There will be no false broadcasts,
Broadcast with good timing can be obtained.

[0030]

As described above, according to the present invention, even if the broadcast content is increased and complicated, the broadcast content can be easily edited and changed without error without using an external memory. Not only can an apparatus be obtained, but also an automatic broadcasting apparatus using an external memory as a storage medium on which broadcasting is automatically performed with good timing can be obtained.
