Description

[Detailed Description of the Invention] This invention is installed in a bus, for example, to issue various warning announcements to passengers during operation, such as "turning", "sudden stop", etc., and issuing numbered tickets. If so, please pick up a numbered ticket.
Furthermore, the present invention relates to an in-vehicle public announcement device that makes a dangerous goods announcement, for example, a message such as "Please do not bring dangerous goods into the car."

Conventionally, it has been proposed to automatically make an in-board announcement "Please do not bring dangerous objects" at the boarding entrance of a bus. In this conventional dangerous goods broadcast, a magnetic tape playback device used only for this purpose is provided, and each time the boarding entrance is opened, the magnetic tape playback device is automatically driven to perform one or more dangerous goods broadcasts. It was like that.

However, in-vehicle broadcasting using such magnetic tape playback devices has a relatively short lifespan due to wear and tear on the magnetic tape and playback head, and also includes mechanically moving parts.
Since this is subject to relatively large body vibrations at all times, it is prone to breakage and therefore requires constant repair or replacement.

Some buses have a fare system in which you receive a numbered ticket when you get on the bus, and pay the fare according to the number on your numbered ticket when you get off the bus. In such a case, if you forget to take your numbered ticket, you will have a problem when paying your fare, but there are currently no warnings to remind you to take your numbered ticket. In addition, there have been no announcements to warn passengers to be careful when a bus makes a turn during its operation. If the driver attempts to make these warning announcements, the driver will have to do so using a microphone, which increases the burden on the driver, and making such announcements while operating the vehicle may pose a danger to the driver. For some reason, it has not been done at all. For this reason, if the bus was running and suddenly made a large turn, passengers could become upset or even get injured.

Note that conventionally, guidance for each stop has been broadcast. This uses a magnetic tape reproducing device, and is configured so that, for example, when the vehicle starts running from one bus stop, the magnetic tape reproducing device is activated at an appropriate time to broadcast information about the next stop. In actual use, it is difficult to record warning announcements related to operation operations on such magnetic tapes.

An object of the present invention is to provide an in-vehicle public address system that broadcasts various cautions and dangerous materials to passengers in accordance with operation operations, driving operations, etc., and also broadcasts services to passengers as necessary.

According to this invention, a signal is generated in accordance with the operation operation or driving operation, that is, operation operation such as stopping the bus and opening or closing the boarding gate or the exit gate,
Furthermore, a signal corresponding to a driving operation such as when the bus turns in the direction of travel is generated, for example, by a direction indicator, and the message storage section is read out based on these signals.
The message storage section includes in-car announcements corresponding to each signal, warning announcements such as "This bus is turning right," and danger announcements such as "Please do not bring dangerous objects" to the boarding entrance or outside the vehicle. Physical broadcasts and the like are stored as code information. This code information is read out in accordance with the signal from the signal generation section, and the information is supplied to the speech synthesis section. The voice synthesis section receives the information, creates a voice signal, and automatically broadcasts this to the inside or outside of the vehicle.

In this way, a large amount of information can be stored in a semiconductor storage device, for example, without using magnetic tape, by storing the content to be broadcast as encoded information that can be converted into audio information through speech synthesis. It is possible to memorize and easily and immediately select, read out, and broadcast various signals to be broadcast, and has no mechanical parts or consumable parts, and has a highly reliable and long-life interior. A broadcasting device is obtained. Furthermore, it is possible to issue warnings that could not be provided conventionally, thereby improving service to passengers.

Next, an embodiment of the in-vehicle public announcement system according to the present invention will be described with reference to the drawings. 7 in Figure 1
Reference numeral 0 denotes a signal generating section that generates signals corresponding to driving operations, operation operations, etc. For example, if the direction indicator of the bus to which this broadcasting device is attached instructs the bus to turn to the right, a signal is obtained at the terminal 56, and if the bus is to turn to the left, a signal is obtained from the terminal 57. Furthermore, when the exit door is opened, a signal indicating this fact is obtained at the terminal 58, and when a numbered ticket is taken out from the numbered ticket issuer 21, a signal indicating this fact appears at the terminal 59.

Corresponding to each of these signals from the signal generating section 70, data to be broadcast in the car when the signal is obtained is stored in the message storage section 15 as code information. When a signal is generated from the signal generation section 70, the message storage section 15 is read out under the control of the control section 14, and the corresponding data to be broadcast in the car is read out, and the speech synthesis section 16 performs speech synthesis based on the data. is performed, and an audio signal to be broadcast in the car is created, and the audio signal is amplified by the amplifier 17 and supplied to the in-car broadcast speaker 18 or 63.

The processing of the control section 14 can be performed by so-called program control, that is, a microcomputer can be incorporated to perform the processing. Each signal from the signal generation section 70 is supplied to the input/output port 61, and in the control section 14, the signal generation section 70
We are constantly monitoring whether or not a signal has been generated.
When the signal is generated, the signal is captured, it is determined which signal it is, and the storage unit 1 is stored in response to the signal.
Read out 5. The information stored in the storage unit 15 is, for example, for the signal at the terminal 56, as shown in FIG. 11A, "This bus is turning to the right," and for the signal at the terminal 57, as shown in FIG. 11B. "This bus is turning left", "Thank you for riding" for the signal at terminal 58, as shown in Figure 11C, and "Thank you for riding" for the signal at terminal 59, as shown in Figure 11C.
As shown in Figure D, information such as ``Thank you for riding the train, please take your ticket'' or ``Please do not bring dangerous goods'' as shown in Figure 11E, is stored as a code.

This code is a code that can be synthesized by a so-called speech synthesizer, and is stored, for example, as a voice characteristic parameter. Furthermore, for example, as shown in Figure 11A, the broadcast that says ``This bus is turning to the right'' and the broadcast that says ``This bus is turning to the left'' in Figure 11 B, indicate ``left'' and ``right''. There are some broadcast contents that differ only in the following parts and are the same in other parts. Such common speech pieces are stored as codes such as Va ₁ or Va ₇ ,
Variable speech pieces that change like “right” or “left” are
It is stored as a code such as Vb ₇ and Vb ₈ that can be directly reproduced by a speech synthesizer. Regarding the common voice piece, it is stored in area 1 of the storage unit 15 according to its code.
5a and provides the speech synthesis section 16 with a code capable of speech-synthesizing the contents of the common speech piece.

In this example, the message storage section, the control section 14, and the speech synthesizer 16 are used to broadcast information about the bus stop. That is, the first
In the figure, from the start signal generating section 11,
As shown in FIG. 2B, a start signal 12 as shown in FIG. 2B is generated every time the train passes a service stop No. 1 to No. n.
This activation signal 12 may be generated by the driver operating a button at each stop, for example, or it may be generated automatically when the bus starts running and reaches a predetermined speed or higher. This activation signal can be generated in the same manner as the drive signal for the magnetic tape reproducing device in conventional stop guidance using magnetic tape.

The activation signal 12 from the activation signal generating section 11 is applied to the address generator 13, and the address generator 13 generates an address signal corresponding to each stop number. The address signal indicating the stop number from the address signal generator 13 is applied to the control section 14, and the control section 14 reads the message from the message storage section 15 in accordance with the address.
The message storage unit 15 stores this stop guide as a code for each stop. The information read from the message storage section 15 is supplied to a voice synthesis section 16, amplified as an audio signal by an amplifier 17, and further supplied to a speaker 18 for in-vehicle broadcasting to broadcast the stop information.

In this embodiment, the stop information is broadcast for each stop in this way, and a part of the address signal for that purpose is used to further display the fare display 19.
In this case, the display control for the numbered ticket issuer 21 and the display control for the numbered ticket issuer 21 are also performed. That is, in order to control the fare display device and the fare display device, the control memory 22 is first read out using the address signal from the address generator 13, and then the message storage section 15 and the fare display device are controlled by the control signal read out from the control memory 22. 19, and furthermore, a signal for driving and reading out the numbered ticket issuer 21 is obtained.

As shown in FIG. 3, the control memory 22 stores, for example, control data for a plurality of operating systems, and at the beginning of the control data 23 for one system, data 24 indicating the system are R ₁ , R ₂ , It is remembered as... The next lineage data 24
Next, the control data 25 for system guidance broadcasting is K ₁ ,
K ₂ is stored as... Furthermore, various control data 31 for each stop in the system are stored thereafter. That is, stop data 26 is stored for each stop number No. 1 to No. n, and next to the stop data 26, fare display control data 27 for controlling the fare display 19 is stored as C ₁ to C ₂ , . . . ..., and then the stop guidance control data 2
8 are stored as S ₁ , S ₂ , . . . , and then the numbered ticket control data 29 is stored as H ₁ , H ₂ , .
Therefore, the control data 31 for each stop consists of four types: stop data 26, fare display control data 27, stop guide control data 28, and numbered ticket control data 29.
It will consist of two pieces of data.

These control data are sequentially stored in the control memory 22, for example in a shift register format, and are always repeatedly read out in sequence. This control memory 2
The system data 24, the stop data 26 read from the bus stop data 26, and the address generated by the address generator 13 are compared in the comparator 32 as shown in FIG. is stored in the control register 33. In other words, a signal indicating the system to be operated or currently in operation is sent from the system signal generator 34 to the address generator 1.
3 as the upper bit, and the lower bit thereof is sequentially incremented by the activation signal from the activation signal generating section 11 as described above. The system signal 35 from the system signal generator 34 matches the read output of the data 24 indicating the system sequentially outputted from the control memory 22, and the address indicating the current stop from the address generator 13 and the control memory 22 match. When the stop data 26 in that system matches, the following fare display control data 2
7. Three types of control data, ie, stop guide broadcast control data 28 and numbered ticket control data 29, are stored in the control register 33.

In order to store control data in the control register 33 in this way, for example, as shown in FIG. A comparison is made in section 32a, and if the two match, flip-flop 36 is set. For example, system signal 3
5 is set to the system _R1 , when _R1 in the system data 24 is read from the control memory 22, the flip-flop 36 is set and its Q
The output becomes high level, and its Q output goes to gate 37.
given to. On the other hand, the output of the control memory 22 is sent to the address generator 1 in the comparison section 32b of the comparator 32.
The bus stop number is compared with the address signal indicating each stop number given by the address generator 13b in 3, and if the two match, the flip-flop 38 is set.
The high level Q output is given to the gate 37. The output of the control memory 22 is also applied to the gate 37 . Therefore, the current operation system is
At R ₁ , if the next stop is No. 1, then R ₁ is read out from the control memory 22, and later the next three control data, namely the fare The gate 37 is opened only during the period when the display control data 27, the stop guide control data 28, and the numbered ticket control data 29 are read out, and these three control data sequentially pass through the gate 37 from the control memory 22 and are stored in the control register 33. stored within. The control register 33 is composed of, for example, a shift register controlled in synchronization with the read clock of the control memory 22, and the outputs of the flip-flops 36 and 38 are supplied to an AND gate 39, from which a high level output is obtained. The control register 33 is allowed to perform a shift operation only during this period. Moreover, the control register 33
The number of stages is selected to be the same as the length of the three control data 31 for each stop. Therefore, the contents of the control data stored in each control register 33 in each stage correspond to the order in which they were input. The guide control data 28 and the numbered ticket control data 29 are stored in the register section 33h.

In FIG. 4, a bit indicating that the stop data 26 is stored in the control memory 22 is stored, and the bit indicating the stop data is applied to the gate 40.
Furthermore, the inverted output of the comparator 32b is applied to the gate 40. Therefore, in the above example, when stop number No. 1 of system R ₁ is read out and the next control data is read out, the output of the comparator 32b immediately becomes a low level, and the next stop data, that is, No. 2, is read out. When a match is detected by gate 40, flip-flop 38 is reset by its output. Therefore, as mentioned earlier, control register 3
3 stores only the control data for one stop. Similarly, each system data 24 in the control memory 22 is given a bit to indicate this, and that bit is obtained on the signal line 41.
When the AND circuit 42 detects that a signal indicating system data 24 from the signal line 41 and a mismatch output from the comparator 32a are simultaneously generated,
The flip-flop 36 is reset by its output. In this way, only the control data for the stops generated in the address generator 13 in the designated system are stored in the control register 33.

The stop guidance control data in the control register 33 is taken into the control section 14 and broadcast as audio as described above. Various methods can be used for speech synthesis. For example, speech is divided into short pieces of speech that are about the same length as the speech words to be broadcast, and each piece of speech is memorized as characteristic parameters and pitch, and this is used to synthesize the speech to be synthesized. Read out the necessary parameters depending on the piece and synthesize it.

For example, as shown in FIG. 5, the system information announcement is made such as ``This bus is going to 〇〇 system 〇〇.'' In this case, only 〇〇 indicating the system and 〇〇 indicating the destination differ depending on the system. In this way, all system guidance broadcasts have common parts and variable parts that differ from system to system.
Therefore, by distinguishing these and storing common parts as codes indicating their contents, the storage capacity of the message storage section can be reduced.

In Figure 5, “This bus is” is a common voice piece.
Va ₁ , “〇〇” for 〇〇 system is a variable speech piece.
Vb ₁ , "system" is a common speech piece Va ₂ , "〇〇" for destination is a variable speech piece Vb ₂ , "I'm going" is a common speech piece Va ₃ , common speech pieces Va ₁ , Va ₂ , Va ₃ are given symbols to indicate each.

Correspondingly, the control memory 22 in FIG.
The control data 25 for system guidance in Fig. 3 inside
As shown in FIG. ₆ , for example, a common speech piece Va ₁ , a variable speech piece Vb ₁ , a common speech piece Va ₂ , a variable speech piece Vb ₂ , and a common speech piece Va ₃ are respectively stored for K 1 . These system guidance control data from the control register 33 are taken into the control unit 14, and the control unit 14 reads each common voice piece Va from the description 15a, and reads out characteristic parameters etc. necessary for generating the voice piece. Then, characteristic parameters and the like are also read out from the storage unit 15b for the variable speech piece Vb. These read feature parameters and the like are sequentially sent to the speech synthesis section 16. The speech synthesis section 16 is constituted by, for example, a pitch frequency oscillator, a noise generator, and a digital filter whose characteristics are controlled by characteristic parameters, and is sequentially reproduced as a digital signal and converted into an analog signal as a continuous signal.

The control unit 14 can use a so-called microcomputer, and therefore, the processing procedures performed by the control unit 14 are stored as a program, and a program memory is also used for reading and writing data necessary for various processes. It has built-in readable and writable memory. The microcomputer in the control section 14 can also be used to control the synthesis processing in the speech synthesizer 16.

In this way, address generator 1 is generated for each stop.
Control data for broadcasting is read out from the control memory 22 in accordance with each address from 3, and the common voice piece and variable voice piece in the message storage unit 15 are read out and further edited based on the control data. The speech is synthesized by the speech synthesizer 16, and a stop guide broadcast corresponding to the system or stop is broadcast to the inside of the car through the speaker 18.

Note that the system guidance control data 25 is stored in the control register 3.
In FIG. 3, data corresponding to stop number data 26, fare display control data 27, and numbered ticket data 29 are automatically stored in the register section 33s of No. 3, before and after the system guidance control data 25. No. 0, C ₀ and H ₀ are stored respectively. Furthermore, if necessary, the data C ₀ is used to control the fare display 19, and the data H ₀ is used to control the numbered ticket issuer 21.
It is also possible to reset each to the initial state.

For example, as shown in Figure 7, the stop information broadcast will be something like ``Next is 〇〇''.
In this case, "next wa" and "desu" are common speech pieces Va ₄ and Va ₅ , respectively, and "〇〇" indicating a stop is stored as a variable speech piece Vb ₆ .

As mentioned earlier, in this embodiment, the fare display is also controlled, and the fare display is, for example, a so-called triangular table as shown in FIG. 8, and the ticket numbers _H1 to _{H6 are} displayed. and fare section number C ₁ ~
The table shows the fares corresponding to C6 and _C6 , and this table shows that, for example, a person with ticket number _H2 will pay 100 yen if he gets off at section _C3 , or a person with ticket number H2 will pay 100 yen if he gets off at section _C5 .
This indicates that if you get off the train at , you will have to pay 130 yen. Data representing this table is stored in the fare data memory 45 of FIG. The storage state is shown in FIG. 9 for the case of the table shown in FIG. That is, regarding the system data 24 shown in FIG. 3, fare data 46 corresponding to the fare table is stored for each of the fare display control data 27C ₁ , C ₂ , C ₃ , . . . in FIG. 3 for each system. There is. That is, in FIG. 8, for section _C1 , only 8 indicating the fare of 80 yen for ticket number _H1 is stored as fare data 46, and after _C2 , which is the next control data 27, serial number H is stored. Fares 100 yen and 80 yen for ₁ and H ₂
Data 10 and 8 indicating yen are sequentially stored as fare data 46. The following information is stored in the same manner.

This fare data 46 is read out according to the contents of the control register 33, that is, the control data 27 of the register section 33c. This reading is performed by comparing the control data from the register section 33c, the system command 35 from the system command generator 34, and the read contents of the fare data memory 45 using a comparator 48, and displaying the required fare data based on the comparison result. The fare is stored in the register 49 and the fare is displayed on the display 19.

In this way, only the necessary contents of the fare data memory 45 can be stored in the fare register 49 in the same manner as described with reference to FIG. 2, for example. That is, as shown in FIG. 10, the data read out from the output of the fare data memory 45 and the system signal 35 from the address generator 13a are compared by the comparator 48a, and the readout of the memory 45 corresponds to the fare of the specified system. When the beginning of the data string is detected, flip-flop 50 is set. Thereafter, the fare display control data 27 obtained in the register section 33c of the control register 33 in FIG.
1 is set. flipflop 50 and 5
Each Q output of 1 is supplied to an AND gate 52, and when they match, that is, when the fare display control data 27 indicating the current section in the designated system is read, the gate 52 is opened and the data is input from the fare data memory 45. The readout output of , that is, the next fare data 46 is stored in the fare data register 49 through the gate 52 .

An address counter 53 is provided to generate an address signal for storage in this register 49, and the address counter 53 counts the read clock of data in the fare data memory 45, and the output of this counter 53 is sent to the fare data register 49. Given as an address. For the flip-flops 50 and 51, a mismatch is detected from the corresponding comparators 48a and 48b, and the presence of a bit indicating that it is the system data 24 obtained from the memory 45 and the section data, that is, the fare display control data. Due to the presence of the bit indicating 27, the mismatch output at that time causes flip-flops 50 and 51 to be reset, respectively. The counter 53 is reset by the reset output of the flip-flop 51. In this way, each time the fare display control data 27 is detected in the fare data register 49, the contents of the subsequent fare data 46 are stored at a predetermined address. The contents of the fare data register 49 are read out by the drive circuit 54 for the display 19 and displayed.

In order to control the numbered ticket issuer 21 in FIG.
In step 5, for example, binary-decimal conversion is performed,
This numbered ticket control data is given to the numbered ticket issuer 21, and a numbered ticket with a corresponding number is issued. This issuance control is performed in the same manner as the control for the conventional numbered ticket issuer 21. For example, a pulse motor is provided in the numbered ticket issuer 21, and when it is detected that the rotation angle of this pulse motor matches the input numbered ticket control data 29, the rotation of the motor is stopped. A numbered ticket with a number corresponding to the number is issued.

FIG. 11D for the signal obtained from terminal 59.
Alternatively, if the content shown in E is to be broadcast, it is not necessary to broadcast it to all passengers, but only to those who are boarding the train. Therefore, if you want to broadcast only to people who are boarding the train, for example, as shown in FIG.
2, the output of the amplifier 17 can be switched from the speaker 18 for in-vehicle broadcasting to the speaker 63 provided at the bus entrance.

In addition, a message such as "Thank you" to passengers getting off the train can be sent by installing a speaker near the exit, and a message to the driver can be sent through a speaker installed near the driver's seat.

The address generated by the address generator 13 is given to the stop number display 64 so that it is possible to monitor what kind of stop signal, that is, address signal, is currently being generated. The stop number generated by the address generator 13 is displayed. Also address generator 1
3 can decrease or increase the address by 1 by controlling the address controller 65. For example, each time the operating lever of the address controller 65 is operated, a pulse is given to the address generator 13, and by changing the operating direction of the operating lever to either the left or right (or up or down), the address generator is activated. Reference numeral 13 is a reversible counter that advances by one step or subtracts by one. Therefore, the driver can easily set the address generator 13 to an address corresponding to an arbitrary stop number.

As described above, according to the information broadcasting device according to the present invention, the message is stored in the message storage section without using a magnetic tape playback device, and what is stored as a code is read out.
It has a long life and is highly reliable. Furthermore, it is possible to make announcements based on driving operations that were previously impossible, such as warnings such as "turn right" or "turn left," which further improves safety and service for passengers. . Furthermore, when applying the brakes, it has been proposed to provide a visual display, but the warning display is useless unless the user is looking at the display, but if the brake operation is announced by voice, the visual display can be displayed. Passengers who are not aware of the situation are also warned, increasing safety. Furthermore, in addition to providing services such as ``Thank you for your ride,'' we also need to be careful to take the numbered ticket, even though we often forget to take it, to avoid any trouble when paying wages. I can do it. In addition, since the in-vehicle announcement is automatically made, there is no burden on the driver, and this allows him/her to pay attention only to driving and operation, resulting in safer and more accurate driving. Operation becomes possible.

Furthermore, the storage formats of the control memory 22 and fare data memory 45 and the storage devices used may be other formats. In other words, data is output to an address that is constantly read and matches the address of the address generator, but the required amount of data is output according to the address from the address generator 13 without constantly reading the memory. The memory may be read using an address created based on the reference. Additionally, a message storage section 15
In particular, the storage unit 15b for the variable speech segment may be a readable/writable memory so that it can be corrected when the route is changed, or it may be configured such that only that part can be replaced. . Although a microcomputer is used as the control unit 14 in the above description, it may be configured as a circuit. Further, the microcomputer of the control unit 14 is used to generate an address for the address generator 13, and necessary control data is taken in from the control memory 22, and further, the control data is used to read fare data. Various processes such as storage in the fare data register 49 can also be performed.
