Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to a device that can automatically broadcast various information on a one-man bus, and uses a voice synthesizer to electronically reproduce the voice, so that a wide variety of information can be set on a single device. Moreover, the purpose is to enable a part of them to be repeatedly broadcast for a necessary period of time, and to make it possible to easily change the broadcast contents.

[Conventional technology]

Conventionally, guidance announcements on one-man buses have generally been carried out using tape recorders, and mainly only the name of the next stop during operation is broadcast inside the bus. This is because the storage medium is magnetic tape, which does not have a large storage capacity, and the information must be recorded in series in the order in which it is broadcast, for example, every time the information is stopped at a stop. If we were to broadcast the destinations for each route outside the train, we would have to record the information between each stop name and other information, which would be physically impossible, so we would like to reduce the information to the minimum necessary. This is because they are being held back.

[Problem that the idea aims to solve]

The drive of the tape recorder mentioned above is started by the driver by operating a push button etc. every time the vehicle starts.
If multiple tape recorders are installed, such as one for broadcasting information on bus stop names and one for broadcasting destinations by route system, it is not only uneconomical and large-scale, but also requires drivers to perform various tasks. This will force you to operate the vehicle, which will affect safe driving. Furthermore, magnetic tape has drawbacks such as it is difficult to change only part of the recorded content due to changes in stop names or routes, and it is subject to wear. In addition, for example, if the boarding door is open and passengers are boarding, if the information such as the destination is announced only once, it may be missed or misheard due to noise, etc., and the boarding order However, there is a problem in that the person behind is too far away to hear. Also, while there are people on board, it is necessary to repeat the broadcast many times, but with conventional methods such as tape recorders, it is necessary to repeatedly record the same content or rewind and play it many times. Therefore, there are problems in that the recording tape and playback device become large-scale and the operation becomes complicated. Alternatively, it is necessary to specify the number of repetitions, etc. Since the number of repetitions is undefined depending on the conditions,
It's unrealistic. The present invention has been made for the purpose of providing an innovative guidance broadcasting device that eliminates all of the various drawbacks mentioned above.

[Means to solve the problem]

The automatic guidance broadcasting device for one-man buses of the present invention includes a destination setter that is set with a predetermined system number for each operating route, and outputs an output signal corresponding to the set system number, and a higher-order address. Code numbers assigned to each type of word/phrase are stored in advance in memory addresses designated by the designation signal and the lower address designation signal in accordance with the order of the words in the guidance broadcast, and the upper address designation signal a semiconductor memory from which a corresponding code number is read by specifying a lower address designation signal and a lower address designation signal; a drive command output means for outputting a drive command signal in relation to a passenger door opening/closing signal; and a drive command output means from the destination setting device. outputs an upper address designation signal corresponding to the output signal of the controller, and each time a specific code number indicating the end of a word in the broadcast content is read from the semiconductor memory only while the drive command signal is being output. A code conversion circuit that outputs a series of low-order address designation signals that are repeated in sequence, and a speech synthesizer that outputs a synthesized voice of words corresponding to each code number read from the semiconductor memory through a speaker. .

[Effect]

According to the present invention having the above configuration, the upper memory address of the semiconductor memory corresponds to a system number predetermined for each operating line, and the lower memory address corresponds to a code assigned corresponding to each type of word/phrase. Since the numbers are stored in advance in accordance with the order of the words in the guidance broadcast, while the drive command signal is being output in conjunction with the opening/closing signal for the passenger door, the last word in the broadcast content can be read from the semiconductor memory. A series of lower address designating signals are repeatedly output each time the specific code number shown is read out.

The upper memory address corresponds to the system number, and the lower memory address stores words and phrases of predetermined broadcast content for each system number using code numbers. For example, as shown in the figure, if you want to broadcast the message "This bus is bound for Kitahama via Route 75 Osaka Station," the code numbers "1, 16, 4, 21, 3,
24, 2". Reference numeral 16 denotes a boarding door control section as a drive command output means that outputs a drive command signal S1 in relation to the opening/closing signal of the boarding door. Reference numeral 4 denotes a code conversion circuit that extracts a predetermined code number from the semiconductor memory 3, and converts the output signal S12 of the destination setting device 1, the drive command signal S1 output from the boarding door control section 16, and the route point of the one-man bus. It outputs an upper address designation signal S3 and a lower address designation signal S4 to the semiconductor memory 3 in response to a transit stop passage signal S2 output from the fare display when passing through. Hereinafter, the constituent elements of the code conversion circuit 4 will be explained. Reference numerals 5 and 6 designate an input interface for converting the output signal of the destination setter 1, and a latch circuit for latching the signal and outputting it to the semiconductor memory 3 as an upper address designation signal S3. Similarly, 7 and 8 are respectively drive command signals S1
With the interface and latch circuit of 9,10
are an interface and a latch circuit for the intermediate stop passage signal S2, respectively. The gate timer circuit 11 has the following functions. When the drive command signal S1 is input, the counter circuit 12 outputs a reset signal S10 that sets the lower two bits of the lower address designation signal S4 to "00", and the speech synthesizer 1
Start signal S for starting speech synthesis in step 3
Outputs 8. Audio output end signal S from the audio synthesizer 13
When 6 is input, it outputs a count signal S7 that increments the lower two bits of the output data of the counter circuit 12, and also outputs a start signal S8 that starts voice synthesis in the voice synthesizer 13. When the reset control signal S5 (code number "2" in FIG. 2) indicating the end of the word in the broadcast content and the audio output end signal S6 are input from the semiconductor memory 3, the counter circuit 12 outputs the lower address designation. It outputs a reset signal S10 that sets the lower two bits of the signal S4 to "00" and also outputs a start signal S8 that starts voice synthesis in the voice synthesizer 13. When the drive command signal S1 is no longer input, the start signal S8 is not output. When the intermediate stop passage signal S2 is input, a preset signal S1 is generated to preset the value of the upper two bits of the lower address designation signal S4 to a specific value.
1 (for example, "01") is output, and the upper two bits of the counter circuit 12 are preset to "01". Until the intermediate stop passing signal S2 is input,
The value of the upper two bits of the lower address designation signal S4 is "00". 12 is a counter circuit 12 that outputs a lower address designation signal S4 to the semiconductor memory 3. The upper two bits of the lower address designation signal S4 are preset to predetermined values ("00" and "01" in FIG. 2) by the preset signal S11, and the lower two bits of the lower address designation signal S4 are It is incremented by the count signal S7 ("00" to "06" in FIG. 2), and is reset to "00" when the reset signal S10 is input. 13 is a speech synthesizer, which includes a clock generator,
It is composed of LSI, ROM, interface, etc., and uses an electronic circuit that simulates the human body's vocal production mechanism, and a signal that analyzes the original voice, encodes its characteristics, and records it in memory. It is something to be reproduced. In the embodiment, the combination of words and phrases is made possible by the action of a microcomputer, and the main voice signal is the voice signal of the word or phrase corresponding to each code number, which is sequentially input from the semiconductor memory 3 as the control signal S9, and this voice signal is sent to the amplifier. After being amplified by the speaker 14, the synthesized voice is output from the speaker 15. Next, to explain the operation of the embodiment device configured as described above, the system number is set by the destination setting device 1, and the destination display is displayed on the destination display 2 on the front, side, and rear of the one-man bus. , the upper address designation signal S is sent from the code conversion circuit 4 in response to the output signal of the destination setter 1.
3 is output, and in the semiconductor memory 3, the upper memory address corresponding to the set system number is designated. Let's take system number "75" as an example. When the destination setter 1 is set to the system number "75", an upper address designation signal S3 is output in response to the output signal S12. When the one-man bus in operation arrives at the stop and the boarding door opens, the drive command signal S1 is sent to the gate via the interface 7 and latch circuit 8.
The signal is input to the timer circuit 11. If the drive command signal S1 is input when the transit stop passing signal S2 is not input, that is, when the upper two bits of the lower address designation signal S4 output from the counter circuit 12 are "00", the above function is executed. Accordingly, the gate timer circuit 1
1, a reset signal S10 is output, and the lower two bits of the lower address designation signal S4 become "00". At this time, the upper memory address of the semiconductor memory 3 becomes "0001" by the upper address designation signal S3, the lower memory address becomes "0000" by the lower address designation signal S4, and is stored at the combined memory address "00010000". has been done. "1"
The code number is read out, and this code number is input to the speech synthesizer 13 as a control signal S9. In the speech synthesizer 13, the control signal S9 is inputted, and the start signal S8 is also inputted from the gate/timer circuit 11 by the function, so that the synthesized signal corresponding to the code number "1" is inputted. The audio signal "Kono bus wa" is output, amplified by the amplifier 14, and output from the speaker 15. When the output of the synthesized audio signal "Kono bus wa" corresponding to the code number "1" is completed, an audio output end signal S6 is output. When this audio output end signal S6 is input to the gate/timer circuit 11, the above function causes
It outputs a count signal S7 and a start signal S8. The counter circuit 12 increments the lower two bits of the lower address designation signal S4 from "00" to "01" by up-counting using the count signal S7. The code number "16" stored in the synthesized address "00010001" is then read out and input to the speech synthesis device 13 as a control signal S9. In the speech synthesizer 13, the control signal S9 is input, and the gate
Since the start signal S8 from the timer circuit 11 is also input. Synthesized speech "75" corresponding to the code number "16" is output. Synthetic voice “75” corresponding to the code number “16”
When the output of is completed, an audio output end signal S6 is output. In this way, the lower two bits of the lower address output from the counter circuit 12 are sequentially incremented, so that the synthesized voice corresponding to the data from addresses "00010000 to "00010006" says, "This bus is route 75 via Osaka Station Kitahama. "On my way" is output. Code number "2" indicating the end of the word in the broadcast content
When the reset control signal S5 is output, the gate/timer circuit 11 outputs a start signal S8 and a reset signal S10 by the above function. In the above explanation, the code number "2" indicating the end of the word in the broadcast content was used as the reset control signal S5, but this code number "2" also serves as the word "go". , for example, another code number such as "0" may be used as a dedicated code number indicating the end of a phrase in the broadcast content. The reset signal S10 may be output when this code number "0" is read. This reset signal S10 causes the lower address designation signal S4 output from the counter circuit 12 to
The lower two bits of are reset to "00". Therefore, the lower address designation signal S4 outputted from the counter circuit 12 repeats between "0000" and "0006", and the synthesized voice "This "Bus 75 is bound for Kitahama via Osaka Station" is displayed repeatedly. Then, when the drive command signal S1 is no longer input, the start signal S8 is not outputted by the function, so the output of the audio signal is stopped. When the drive command signal S1 is input again,
As shown above, the synthesized voice ``This bus is bound for Kitahama via Route 75 Osaka Station'' is repeatedly output. The above is an explanation of an example in which synthesized speech based on the drive command signal S1 is output. Next, when the transit stop passing signal S2 is input to the gate/timer circuit 11, the function causes the gate/timer circuit 11 to change the value of the upper two bits of the counter circuit 12 to a specific value, for example, "01'' is output. As a result, the upper memory address of the semiconductor memory 3 remains "0001", and the upper two bits of the lower memory address are changed to "01". Therefore, if the drive command signal S1 is input after the intermediate stop passage signal S2 is input, that is, when the upper two bits of the lower address designation signal S4 output from the counter circuit 12 are "01",
According to the above function, the gate timer circuit 11
The lower two bits of the lower address designation signal S4 outputted from the counter circuit 12 become "00" by the reset signal S10 outputted from the counter circuit 12. Therefore, the upper address designation signal S3 of the semiconductor memory 3 is "0001", and the lower address designation signal S4 is "0100". Then, the code number “1” stored in the combined memory address “00010100”
is read out, and the speech synthesizer 13 receives the start signal S from the gate/timer circuit 11.
Since 8 is also input, the synthesized audio signal ``Kono bus wa'' corresponding to the code number ``1'' is output. When the output of the synthesized voice "Kono bus wa" corresponding to the code number "1" is completed, a voice output end signal S6 is output. When this audio output end signal S6 is input to the gate/timer circuit 11, a counter signal S7 is output. In the counter circuit 12, the lower two bits of the counter circuit 12 are incremented by the count signal S7, and the lower two bits of the lower address designation signal S4 are incremented from "00" to "01". The code number “16” stored in the combined address “00010101”
is read out, and the corresponding audio signal "75" is output. When the output of the audio signal "75" corresponding to the code number "16" is finished, the audio output end signal S
6 is output. In this way, the lower two bits of the lower memory address output from the counter circuit 12 are sequentially incremented, so that the address "00010100"
A synthesized voice corresponding to the data from 00010104 to ``This bus is route 75 bound for Kitahama'' is output. When the last code number "2" of the word in the broadcast content is output, the reset control signal S5 is output, and the audio output end signal S6 is output, the gate/timer circuit 11 outputs the reset signal S10. . This reset signal S10 causes the lower address designation signal S4 output from the counter circuit 12 to
The lower two bits of are reset to "00". Since the upper two bits of the lower memory address are designated as "01" by the preset signal S11, the lower address designation signal S4 output from the counter circuit 12 repeats between "0100" and "0104". The synthesized voice signal ``This bus is route 75 bound for Kitahama'' corresponding to the data from memory addresses ``00010100'' to ``00010004'' in the semiconductor memory 3 is repeatedly output. Then, when the drive command signal S1 is no longer input, the start signal S8 is not output, so the output of the audio signal is stopped. After this, when the drive command signal S1 is input, the upper two bits of the lower memory address remain designated as "01" by the preset signal S11, so the synthesized voice "This bus" is output as described above. 75 bound for Kitahama" is repeatedly output. In the above-mentioned embodiment, the explanation has been given of the guidance broadcast of destinations by route, but it goes without saying that the present invention can be applied to all kinds of guidance broadcasts, such as stop names, fares, etc. Further, in the embodiment, the passenger door open signal is used as the drive command signal, but the passenger door close signal may be inverted to obtain a signal equivalent to the passenger door open signal. In any case, it is sufficient to obtain the drive command signal from the passenger door opening/closing signal.

[Effect of the idea]

As described above, according to the automatic guide announcement system for one-man buses of the present invention, the voice synthesizer is controlled by the code number stored in the semiconductor memory with a large storage capacity to broadcast the guide. Unlike conventional magnetic tape, there is no need to store information in the order in which it is broadcast, and a single device can broadcast a variety of information such as stop names, fares, and destinations for each route, providing sufficient information to passengers. This service allows passengers to get on and off the train smoothly and with peace of mind, thereby avoiding unnecessary crowding, which is especially good news for visually impaired people. In addition, destination guidance by system, which has not been done in the past, can be done automatically every time a one-man bus arrives at a stop, which prevents troubles caused by boarding the wrong bus. Since guidance broadcasts with the same content can be continuously and repeatedly broadcast while a drive command signal such as a passenger door opening signal is being output, there is no chance of missing or mishearing due to noise etc. Furthermore, unlike magnetic tape, it has the great advantage that it is extremely easy to change or add recorded content and there is no wear and tear, and the present invention is revolutionary and has significant practical effects.
