Description

[Detailed Description of the Invention] (Technical Field) The present invention utilizes a transmitter attached to each stop when a bus is in operation, a receiver attached to the bus in operation, and an audio message that outputs a message in response to a received signal. Synthesis (1)
-G7' This relates to a notification system in which a message such as the name of the stop is automatically announced to the inside of the train for each stop.

(Background technology) Conventionally, when operating a one-man bus, etc., as the bus approaches each stop, the driver operates a tape recorded in advance with a tape recorder, etc. in the order of stops, and records it inside the bus. In this traditional method,
This system requires the driver's own operation during operation, resulting in a lack of operational safety, and also has short mechanical lifespans because it uses a device with a mechanical part, such as a tape recorder, as the audio output device.

(Problems to be solved by the invention) The purpose of the present invention was to eliminate the following drawbacks, and to eliminate unnecessary operations by drivers of buses, etc., and to provide a voice synthesizer composed of semiconductor elements as a voice output device. It provides an automatic notification system with a long mechanical life using (2) a transmitting device that outputs radio waves corresponding to the symbol; a receiving device that is installed on a moving object passing through the fixed point and receives and decodes the signal; and a receiving device that is installed on the moving object and compresses the information in advance. a storage unit that stores the audio data stored in the memory;
It has a control unit that selects desired audio data from a storage unit in accordance with the decoding of the receiver, and a voice synthesizer that synthesizes and outputs audio from the selected audio data, and has a control unit that selects desired audio data from a storage unit according to the decoding of the receiver, and a voice synthesizer that synthesizes and outputs audio from the selected audio data. It is in the operation information notification system that provides notifications related to.

(Structure and operation of the invention) FIG. 1 shows an embodiment of the invention. 1 is a bus stop, which has a built-in transmitter 2 that transmits a signal 5 indicating the location, and when a bus 3 in operation approaches the stop 1, the signal 5 is received through an antenna 4 attached to the bus. Then, it is decoded by a receiver 6 provided inside the bus, and audio data of the content to be announced inside the bus is selected from the storage section of the voice synthesizer 7, synthesized, and announced inside the bus.

The operation of the transceiver according to the embodiment of the present invention will be explained in detail with reference to FIGS. 2 and 3. The transmitter 2 has a frequency f Tra
The transfer format used in the R, 5232C interface, etc., in accordance with the data setting section 9, which can arbitrarily set the carrier wave α generated by the ns oscillator 8 and 1-byte data representing the position, i.e., the start pitch indicating the start of data)
10 Continuously generates serial data at a constant cycle using a format consisting of ba, accompanying data b1 to b8, and a stop pit bE indicating the end of data.
The output waveform G of the signal generator is multiplied by the output waveform G of the signal generator G by the multiplier 11 to generate the transmission signal wave G.

The receiver 6 receives the transmission signal of C through the antenna 4, and tunes this received signal to the transmitter carrier frequency fTran in the tuning section 12.
This demodulated signal is shaped into a waveform to be compared with the threshold level V814 by the comparator 13, decoded by the serial data decoder 15, and 1 byte indicating the position is demodulated by s. Recognized as data.The carrier frequency fTran8 is in the long wave region and is 100KHz.
~300T(I(z), transmitter power is 0.1W~
IW or a transmission baud rate of 1280 BPS or less is sufficient. As a speech synthesizer, Coronasha Co., Ltd., Acoustic Engineering Course, edited by the Acoustical Society of Japan, "Speech", by Kazuo Nakata, p.64~

PCM (adaptive PCM) method, ADPCM (adaptive differential PC
M) method, PARCO method (partial autocorrelation) method, editing synthesis method, etc. can be used, and the configuration of the speech synthesizer of this embodiment will be explained below.

The voice synthesizer 7 compresses and stores the voice necessary for the announcement according to one of the voice synthesis methods mentioned above, and also includes a storage section 16 in which storage address information of each voice data is also stored, and the output of the receiver 6. a microprocessor section 17 that retrieves audio data according to the information from the storage section 16;
A voice synthesis section 18 is also configured to synthesize the extracted voice data using the same method as the compressed information and output the voice, and the voice synthesized by the voice synthesizer 7 is announced to the inside of the car through a speaker 19. As the storage section, for example, a solid-state storage device made of a semiconductor is used.

Based on the above configuration, specific operations will be explained with reference to the flowchart in FIG. 4, the parameter table in FIG. 5(a), and the storage map in FIG. 5(b). When the bus departs, the counter unit 14 is reset by turning on the power of this speech synthesizer, and an announcement is made at the start, for example, ``Thank you for riding the bus.'' This bus goes to ×○ via ××. '' is taken out from the storage unit 15 and synthesized and output. This audio data is stored in advance at the address AST of the storage unit 15.
This is what I wrote from ART.

After the above announcement ends, the soft timer of the microprocessor section 16 outputs the counter section 14 (in this case, the counter section output remains in the reset state, so it corresponds to O)
After tosec, an announcement of the name of the next -1 stop, etc., such as "Ping Bonpan, the next stop is Fu 1. If you want to get off, please let us know by pressing the nearest alight button." is synthesized and output.

Delay time t from when the train departs until audio output. are stored in advance as parameters in the storage unit 15 as shown in FIG. 5, depending on the intervals between each stop, route conditions, etc.

The sounds that are common to the announcements for each stop except for the "M1" sound are written from address AcoM in the storage unit 15, and are used many times when announcing the name of each stop. The stop name of 11'' is the output of counter part]4 (in this case, it is 0 because it is in a reset state) and the memory part address A.
. It is obtained by synthesizing the audio data written in the storage unit 15 from .

When the next stop approaches and there is a notification 13 from the receiving unit 6, the count of the counter unit 14 is amplified. 5 according to the output (in this case 1), after SeC, the stop name is the voice data written in the storage unit 15 from the address A1, and the other parts are the address ACOM of the storage unit 15. Synthesize and output using the audio data written in the above.

Similarly, the sound is output for each stop, and after the train departs from the last stop. - After I Sec, the end point announcement, for example, "Ping Pong Pan, next is the last stop. Thank you for riding." is synthesized and output. Similar to the announcements of each stop name, etc., the common part is ``Ping Bong Pan, next is -''.
It is also possible to use the same voice data for "Thank you for your ride."

(Effects of the Invention) As explained above, by using the speech synthesizer of this embodiment, the announcement car at each stop can be completely automated, and the driver can only engage in driving, improving operational safety. Ru. Furthermore, since a voice synthesizer made of semiconductor elements is used for audio output, there is no mechanical deterioration due to vibrations during bus operation, and the bus can be used semi-permanently.
