Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial field of use" The present invention relates to a data generator for a guidance broadcasting device for guiding a destination and the next stop name in a vehicle such as a bus.

"Prior Art" The applicant of the present invention has previously described "Japanese Patent Application No. 58-52200" and "Japanese Patent Application No. 58-9".
No. 4621 ”proposed a data generator for guidance broadcasting equipment.

The guide broadcasting data generator proposed earlier stores audio data in the memory and reads out the audio data sequentially, for example, "This bus goes to Tokyo, Shinagawa, via Shinjuku. Please do not bring dangerous goods." It is a data creation device for broadcasting such destination guidance outside the vehicle.

In other words, if the destination guidance that is repeatedly broadcasted outside the vehicle at each stop is recorded on the magnetic tape for guiding the inside of the vehicle to guide the next stop name while the vehicle is running, the magnetic tape becomes long.

For this reason, in the previous proposal, voice data is written in advance in the semiconductor memory, and the destination guidance broadcast is performed by reading the voice data.

"Problems to be solved by the invention" Even if the destination guidance is reproduced by the audio reproducer configured by using the semiconductor memory, the in-vehicle guidance broadcast is still reproduced by the magnetic tape reproducer. As a result, two systems of audio reproducers, a magnetic tape reproducer and an audio reproducer using a semiconductor memory, must be mounted.

It is difficult for a magnetic tape player to maintain its performance for a long period of time because the tape running system is mechanical.

Further, the magnetic tape has a drawback that it wears because it is in sliding contact with the magnetic head, and that the magnetic head also wears and must be replaced periodically.

Furthermore, when the route of the route is changed, all the magnetic tapes for in-vehicle guidance broadcasting must be rewritten, so it takes time to rewrite and the management is troublesome.

An object of the present invention is to provide a data broadcasting device for a guidance broadcasting device in the case where all the guidance broadcasting is reproduced by an audio reproducer using a semiconductor memory regardless of whether it is an in-vehicle guidance broadcast or a destination guidance broadcast. To do.

"Means for Solving Problems" In the present invention, A. an audio signal detecting means for detecting the presence or absence of an audio signal given from the outside for each word representing the broadcast content, and B. a clock while the audio signal is present Address data generating means for counting and generating address data, and C. AD for converting a voice signal into digital voice data
Audio data storage that stores audio data corresponding to all words and phrases necessary for expressing broadcast contents by converting the address and stepping the address by the count value of the address data generator and sequentially storing the audio data. Means, E. audio signal detection means automatically counts each time the presence of an audio signal is detected, and a data number addition means for attaching a data number to each audio data, and F. added by this data number addition means Address data storage means that sequentially stores the address data corresponding to the head and end of the voice data at the address corresponding to the number, G. Number of each route, and the outside bus stop and destination name for each route The respective data, the control data for deleting the name of the transit stop, and the data indicating the destination name are sequentially input, and the data indicating the name of the stop for in-vehicle broadcasting is distinguished from these. H. The route number entered from this input means, the data indicating the outside bus stop name and the destination name, the deletion control data, and the in-car stop name. And the order data storing means for storing as order data for each route number in the input order, and I. Route number, address data corresponding to the head and end of the sequence data and its voice data, and these. The data generator for the guide broadcasting apparatus is constituted by the data transmitting means for sequentially reading and transmitting the voice data corresponding to the address data of 1.

[Operation] According to the configuration of the present invention, by inputting the audio signal to be used for the guide broadcasting by dividing it into unit phrases, the input of the audio signal is detected by the audio signal detecting means, and at the same time the address data generating means is detected. The head address data of the word is output and this head address is stored in the address data storage means.

At the same time, in synchronization with the clock, the AD converting means AD converts the audio signal, and the AD converted digital audio data is written in the audio data storing means. At this time, the start address generated by the address data generating means is accessed as the write start address of the voice data storage means, and the voice data is written from the start address.

Voice signals are, for example, "This bus is", "Tokyo", "Shinagawa",
It is composed of phrases such as "Yokohama" and "Shinjuku", and the voice signal detecting means detects the absence of the voice signal when the phrase ends. When the absence of the voice signal is detected, the address data generating means interrupts the clock counting operation, and the end address data output from the address data generating means at that time is written in the address data storing means.

On the other hand, for example, when writing the head address in the address data storage means, the data number adding means counts +1 and writes the count value in the address data storage means together with the address data as the data number of the audio data written in the voice data storage means. .

That is, the data number defined by the data number adding means is given to the address data storage means as an address signal, and the start address and end address of each voice data are written in the address corresponding to the data number to associate each voice data with the data number. To do.

Next, when the second audio signal is input, the AD converting means AD converts the audio signal. At the same time, when the voice signal detecting means detects the presence of the voice signal, the address generated from the address data generating means at that time is written in the address data storing means as the head address of the voice data.

The audio data is AD converted in synchronization with the clock, and the AD converted audio data is written in the audio data storage means in synchronization with the clock. The address data generating means counts the clock and advances the address by +1 in synchronization with the writing of the audio data, and advances the address of the audio data storage means by +1.

Also, the data number adding means increments the count value by 1 when writing the start address of the second voice data in the address data storage means, and takes the incremented value as the data number of the second voice data, and uses that number as the address data. It is given to the storage means as an address signal, and the start address and the end address of the second audio data are written to the address.

When the second voice data is finished and the voice signal detecting means detects the absence of voice, the address data generated in the address data generating means at that time is stored in the address data storing means and the second voice data is written. finish.

In this way, every time an audio signal is supplied, the audio signal is AD converted into digital audio data and written in the audio data storage means. Along with this, the data number and the start address and end address of the data are added to each voice data, and this is stored in the address data storage means.

On the other hand, a number is assigned to the stop name used for destination guidance and each stop name for in-vehicle guidance, and the numbers are input in the order of number to input voice data, address data and data number to the voice data storage means and address data storage means composed of semiconductor memory. Write. If the number of data to be written is set to about 1000, it can be used commonly by at least one business office vehicle even in a large bus operating company.

The above is the description of the method of creating data related to voice data. Next, a method of creating data that defines the contents of the guidance broadcast used on each route will be described.

The route number and the data number of the audio data used on the route are input from the input means, and the broadcasting order of the audio data is defined according to the input order. A tenkey board can be used as the input means. A route number previously assigned to each route and each data number of voice data used on the route are input from the ten key board in the order of broadcasting, and the input sequence data is stored in the sequence data storage means.

The order data is stored separately for destination guidance and in-vehicle guidance. For example, the route number for destination guidance is prefixed with RU, and the route number for in-vehicle guidance is marked with RT at its head. For example, "RU001, RU003, RU005, RU016, RU123, RU499"
Then, input "RT001, RT123, RT300" and memorize it.

To express an example of this in words, it is used for broadcasting such as "This bus goes to Tokyo and Shinjuku via Shimbashi."

Each data stored in each storage means is read by the data sending means and sent to the outside.

By this sending operation, the data can be transferred to and stored in the memory of the audio reproducing device mounted on the vehicle such as each bus. Since the data transfer can be completed in a very short time, the data can be rewritten in a short time even if the number of vehicles is large.

[Embodiment] FIG. 1 shows an embodiment of a guide broadcasting data generator according to the present invention.

Reference numeral 100 in the figure denotes the entire guide broadcasting data generator. In this example, the guide broadcasting data generator 100 shows a case in which the personal computer 3 configures the other parts except the A / D converter 1 and the audio signal detecting means 2.

As is well known, the personal computer 3 is a central processing unit.
3A, ROM 3B containing a program for operating the central processing unit 3A in a predetermined order, voice data input from the outside, route number, number attached to each stop and internally generated address data, data RAM3C, which composes each storage means for storing numbers, etc., and input port 3D
, Output port 3E, input means 3F, monitor television 3H, and the like.

The input terminals of the A / D conversion means 1 and the audio signal detection means 2 are commonly connected, and the common connection point is connected to the signal input terminal IN. The output terminal of the A-D conversion means 1 and the output terminal of the audio signal detection means 2 are respectively connected to the input port 3D of the personal computer 3, and a signal indicating the presence or absence of an audio signal,
Digital audio data obtained by A / D converting the audio signal is input to the input port 3D. Input means 3F is also connected to the input port 3D, and the route number and the number assigned to each stop are input through the input means 3F.

The audio signal detecting means 2 can be composed of, for example, a saturation amplifier. That is, the sound signal is saturated and amplified by the saturation amplifier, for example, “1” while the sound signal is being input.
It outputs a logic level, and when the audio signal is cut off, the output returns to a "0" logic level. When the audio signal detecting means 2 outputs "1" logic, the personal computer 3 determines that an audio signal has been input, and starts counting clocks supplied through the clock signal line 3G connected to the input port 3D. This counting operation is executed by the central processing unit 3A using a partial storage area 20 of the RAM 3C, and this storage area 20 operates as an address data generating means. Therefore, the address data generating means 20 will be hereinafter referred to.

At the same time that the address data generating means 20 starts the counting operation, the central processing unit 3A starts the operation of taking in the AD conversion output of the AD converter 1 through the input port 3D.

The central processing unit 3A stores the voice data taken in through the input port 3D in the memory area 30 of the RAM 3C as the address data generating means 2
The data is sequentially stored according to the address data in which 0 is generated.
Therefore, hereinafter, it will be referred to as the voice data storage means 30.

Further, when the voice signal detecting means 2 detects the presence of the voice signal, the central processing unit 3A is at that time the address data generating means.
The address where 20 is generated is read and written in the storage area 40 of the RAM 3C as the head address data. When the voice signal detecting means 2 detects the end of the voice signal, the central processing unit 3A stores the address data output from the address data generating means 20 at that time in the storage area 40 as the end address of the voice data. Therefore, this storage area 40 will be referred to as address data storage means 40 below.

When the audio signal detecting means 2 detects the presence of an audio signal, the central processing unit 3A performs a counting operation using the storage area 50 of the RAM 3C to count the number of incoming audio signals. This count value is used as an address signal for accessing the voice data storage means 30, and a number is added to the voice data. Therefore, this storage area 50 will be referred to as data number adding means 50 below.

On the other hand, the input means 3F indicates a key board, and numeric values can be input from the ten key board, and digital codes corresponding to alphabets A to Z or kana characters can be input from the main key board.

From the input means 3F, the route number for destination guidance, for example, RU001 to RU0
Enter 03, the route number RT001-RT300 for in-vehicle guidance broadcasting, and the number attached to each stop, for example, 0001-1000. For this input, the numerical value attached to each stop is input in accordance with the broadcast sequence determined in advance for each route and stored in the storage area 60 of the RAM 3C. Therefore, this storage area 60 will be referred to as order data storage means 60.

When the voice data and the sequence data that determines the sequence of guidance used for each route are written, the central processing unit 3A sequentially reads the data stored in each storage unit as necessary and outputs the output port.
Data is sent to the buffer memory 4 through 3E.

The buffer memory 4 is backed up by a battery so that the data is retained even when carried. The buffer memory 4 is connected to an audio reproducing device mounted on a bus (not shown), and the data is injected into a semiconductor memory built in the audio reproducing device.

FIG. 2 shows the relationship between the clock, the audio signal and the address data. FIG. 2A shows a clock pulse. This clock pulse is branched from the clock line of the personal computer 3 to the clock signal line 3G and given to the AD converting means 1 and the input port 3D. The A / D conversion means 1 is constantly supplied with a clock pulse and constantly executes an A / D conversion operation.

FIG. 2B shows an audio signal input to the input terminal IN. Each time an audio signal is input, the address data generating means 20 starts counting clock pulses and generates the head address AR of the audio signal.

The head address AR generated by the address data generating means 20 is given to the voice data storage means 30, the address AR of the voice data storage means 30 is accessed, and the writing of voice data is started from this access as shown in FIG. When the voice signal is cut off, the address data generating means 20 suspends the clock counting operation. The address data generating means 20 is configured to interrupt the counting operation with a delay of at least one clock when the voice signal detecting means 2 detects the absence of the voice signal. By doing so, it is possible to prevent the end address of the previous audio data and the start address of the next audio data from overlapping.

On the other hand, the central processing unit 3A uses the data numbers "0001", "0002" ... "1000" generated in the data number adding means 50 to set the head address "0001" of the address data storing means 40 as shown in FIG. The head address AR ₁ , A of the voice data in the voice data storage means 30 is accessed to this address “0001”.
Write R ₂ , AR ₃ ... and end address BR ₁ , BR ₂ , BR ₃ ....

In this way, every time a voice signal is input, the voice data is written in the voice data storage means 30 in the area of the address according to the end address from the head address generated in the address data generation means 20. At the same time, the address data storage means 40 is accessed according to the data number generated in the data number addition means 50, and the address data storage means 40 is accessed.
Write the start address and end address of each audio data to each address “0001”, “0002” ... “1000”.

When the writing of the voice data is completed, the personal computer 3 is switched to the sequential data input mode. When the sequence data is input, for example, the monitor 3H displays a line number input field 5 and a stop name input field 6 as shown in FIG.

In the route number input field 5, the route numbers RU001 to RU300 with the destination guide code RU and the route numbers RT001 to RT300 with the in-car guide code RT are entered. The maximum value of the route number is 300 in this example, but this number is a number determined by the number of routes handled by each business office, and is not limited to 300.

In the stop name entry field 6, enter the stop number assigned to each stop. This table is written in the sequential data storage means 60 as it is, and the writing of all data is completed.

Here, for the destination guide and in-vehicle broadcast, for example, "This bus is a line", "Don't bring dangerous goods" or "Next""is""If you get off, please press the exit button. There are phrases such as "please".

Data numbers are attached to these words and phrases, and voice data storage means
Although not stored in the broadcast sequence described in the sequence data storage means 60, the data is automatically read out by the voice reproduction device of the bus and combined with the front and rear of the stop name used for destination guidance and in-vehicle guidance. It can be configured to broadcast.

Therefore, since it is configured in this way, only the stop name and other various control signals need to be written in the sequence data storage means 60.

The other control signal is the control data for deleting the name of the stop in the destination guidance, that is, a code indicating the number of stops up to the stop. KU shown in FIG. 5 indicates a code indicating that there is a waypoint, and the numeral 07 added after this code KU indicates the number of stops from the first train to the waypoint. For example, if you select route 001, the destination information from the first train to the seven stops is determined by "0001""0201""0900""0311" For example, "Tokyo, Shinjuku via Shinagawa" So, please do not bring in dangerous goods. We will omit it here because it will be added with a recycling device.) 7 stops
If it passes, it will be changed to "Shinjuku" which is decided by "0311" and simply broadcast "This bus is Shinjuku bound".

In the column for in-vehicle guidance broadcasting, the data number of each stop in the order of stops on route RT001, for example, "0010""0100""0210""10"
You can enter 1 ”,“ 0201 ”, and so on.

The data is created as described above, and the data is written in the RAM3C. Central processing unit with data writing completed
The 3A has a function of reading the data stored in the RAM 3C as necessary and sending the data to the outside through the output port 3E. This data transmission function is performed by the central processing unit 3A executing a program stored in the ROM 3B. Therefore, it can be said that the central processing unit 3A and the ROM 3B constitute a data transmission means.

The data sent from the output port 3E to the outside is stored in the buffer memory 4. The buffer memory 4 has a built-in battery and can maintain the data written in the memory. The buffer memory 4 is connected to an audio reproducing device mounted on the bus, data is injected into the audio reproducing device of each bus,
Can be copied. The voice reproducing device of the bus can also maintain the data by the battery and perform the destination guidance and the in-vehicle guidance broadcast at the next stop as it is until the rewriting is necessary.

"Effects of the Invention" As described above, according to the present invention, for example, 4
By having a storage capacity of ~ 8MB, 0.5 ~ 1
It is possible to memorize about 1000 stop names that end in about a second. By using the name of the stop, destination guidance can be used to broadcast onboard guidance for each route. Therefore, it is possible to perform both destination guidance broadcasting and in-vehicle guidance broadcasting without using a voice reproducer using a magnetic tape.

Further, in the guide broadcasting data generator 100 according to the present invention, when the supply of the audio signal is cut off, the address data generating means 20 interrupts the counting of the clock, so that the audio data storing means 30 does not have a blank portion (unused portion). Therefore, the memory can be used effectively.

Further, according to the present invention, it is easy to create the voice data because the data number, the start address and the end address of the voice signal are automatically created only by inputting the voice signal and the data number and the address data are sequentially stored.

Further, since the sequence data of a plurality of routes can be stored, it is convenient that the same voice data group can be used to perform destination guidance broadcast and in-vehicle guidance broadcast of a plurality of routes.
