For example, when the train approaches, the LED inside the thread line blinks, notifying the train approach and urging attention to prevent falling.

  As a safety measure for visually impaired persons and the like, an embedded block called a Braille block is installed to ensure safety during walking, fall prevention, and the like.

  By the way, in the platform of the station, as a guide to the user, various speakers based on train information such as limited express, express, normal, etc., train information such as number of trains, etc. Voice guidance is provided.

  However, since such voice guidance is performed by the speakers installed above the heads of the respective homes, the sound from the speakers is diffused in all directions, depending on the environment and conditions of the mounting position of the speakers. May be difficult to hear because the sound from each speaker is mixed.

  In order to solve such a problem, it is conceivable to apply a road burying sound generator as shown in Patent Document 1. This is because the block body is provided with a mounting recess whose upper surface is open, and the waterproof surface of the speaker is set in the mounting recess so that the entire periphery is surrounded by a synthetic resin material, and the speaker is synthetic resin on the upper surface. While the layer is thin and used as a vibrating membrane, a plate with a plurality of holes is set on the block body and the upper open part of the mounting recess is closed to enable voice guidance from the feet and ensure accurate guidance guidance It is what I did.

  It is also conceivable to apply a road surface burying block as shown in Patent Document 2. This is because a planar speaker is arranged in an internal space formed below the upper wall portion of the road surface embedding block in parallel with the upper surface of the upper wall portion. Voice guidance.

That is, the boarding / alighting position is a place where each door 101 of each vehicle is located when the train 100 stops at a predetermined position on the platform H of the station.

  Next, the operation of the guidance information broadcasting system having such a configuration will be described. First, when the voice output control device 10 receives the information on the train position from the detection device 1 and the train operation information (diagram information) from the external device 2, the diamond information analysis unit 14 of the voice output control device 10 described above. The guidance control data D1 and D2 are generated and output.

  Next, the voice instruction data output unit 15 of the voice output control device 10 is based on the above-described guidance control data D1 generated by the diagram information analysis unit 14 and the train state output from the train position condition output unit 12. The voice instruction data is output to the voice output device 20. This voice instruction data is output from the train position condition output unit 12 according to which position of the above-mentioned home approach block section K1, home block section K2, and home departure block section K3 the train 100 belongs to. For example, voice instruction data is output every time the train 100 belongs to each of the home approach block section K1, the home block section K2, and the home departure block section K3.

  When the voice output device 20 receives voice instruction data corresponding to any of the home approach block section K1, the home block section K2, and the home departure block section K3, the voice signal generation unit 21 of the voice output apparatus 20 outputs the voice data. The voice data corresponding to the voice instruction data stored in the memory 22 is read, and an analog voice signal is generated. The generated analog audio signal is output to the audio signal line 24 by the high impedance amplifier 23.

  Here, since the matching transformer 30 connected to the input side of each flat panel speaker 41 is connected in series to the audio signal line 24, the audio signal of the high impedance amplifier 23 is given to all the matching transformers 30. It is done. When impedance matching is performed by each matching transformer 30, voice guidance is performed from the flat panel speaker 41 by the audio signal subjected to the impedance matching.

  Here, from each flat panel speaker 41, for example, a voice guidance such as “Please pay attention to your feet as a 10-car train will soon enter the line,” or “Soon a 10-car train will be available. Voice guidance such as “Be careful about your feet as we will be entering the 3rd platform” and “Be careful with your feet as the 10-car train will pass through the 3rd platform.” Voice guidance is provided. These voice guidances are all output according to the train state output from the train position condition output unit 12 of the voice output control device 10 described above.

  Each flat panel speaker 41 is built in the guidance information broadcasting device 40 installed in the platform H of the station, for example, embedded in a tile, so that the sound can be heard from the feet. Therefore, even if the sound from the speaker installed on the head of the home H is diffused and mixed in all directions, the voice guidance is performed in a spot manner, so that the sound from the speaker installed on the head of the home H is It can be heard separately from mixed sounds.

  Thus, in 1st Embodiment, the train output information from the detection apparatus 1 which detects the position of a train for every block section preset by the audio | voice output control apparatus 10, and the train operation information from the external apparatus 2 are demonstrated. Based on the above, voice instruction data that is train information for performing voice guidance is output, and the voice output device 20 outputs a voice signal for voice guidance based on the voice instruction data. Voice guidance based on train information is provided from a guidance information broadcasting device 40 which is connected to the voice output device 20 via a line 24 and has a built-in flat panel speaker 41 which is a speaker arranged side by side along the platform of the station. I was supposed to be.

  In this case, since the guidance information broadcasting device 40 is installed side by side along the platform H of the station, the voice guidance from the guidance information broadcasting device 40 can be heard from the feet, and the voice guidance based on the train information is spotted. Therefore, the voice guidance based on the train information can be heard by distinguishing from the mixed sound from the speakers installed above the head of the home H.

  Here, when the audio signal line 24 from the high-impedance amplifier 23 is connected in parallel to the matching transformer 30, as shown in FIG. 7, four flat panel speakers 41 corresponding to one of the four doors 101. For this, one matching transformer 30 is provided, and the audio signal line 24 from the high impedance amplifier 23 is connected to each matching transformer 30. Further, two flat panel speakers 41 are connected in series to one matching transformer 30.

  In this case, if the output impedance of the matching transformer 30 on the flat panel speaker 41 side is, for example, 8Ω and the input impedance of the flat panel speaker 41 is, for example, 6Ω, the total input impedance of the four flat panel speakers 41 is 6Ω.

  In this case, the user who uses the green car can confirm that the green car stops by the voice guidance, and the customer who does not use the green car can move to another boarding position by the voice guidance.

  Moreover, when the boarding position of the platform H of the station where the user is located is specified, from the above-described train operation information (diagram information), for example, when the boarding position is a position where the female exclusive vehicle stops, It is also possible to provide voice guidance such as “The women-only train stops at the boarding position”.

  As a result, the passenger (female) who uses the female-only vehicle can confirm that the female-only vehicle stops by the voice guidance, and the passenger (male) who cannot use the female-only vehicle can check the other boarding positions by the voice guidance. Can be moved to.

  Further, if a passenger is not detected by any of the sensors 50, the boarding position where the user is not detected is specified. Therefore, the user can be detected by selecting the audio signal line 24 from the high impedance amplifier 23. Voice guidance is also possible only at the designated location.

  Further, when the guidance information broadcasting device 40 and the sensor 50 are arranged at a place where the platform H of the station is curved, and a user or a baby stroller or a wheelchair is detected by the sensor 50, the flat panel speaker 41 reads “Home and train”.

  Here, when the sensor 50 and the audio output control device 10 are connected, as shown in FIG. 23, the sensor 50 is placed in the vicinity of each of the four flat panel speakers 41 corresponding to the four doors 101. The four sensors 50 are connected in series, and the four sensors 50 and the audio output control device 10 are connected by a signal line 51.

  In such a configuration, when a user is detected by any one of the sensors 50, the boarding position of the station platform H corresponding to at least one of the four doors 101 is specified, and the sound from the sound signal output unit 23a is specified. By selecting the signal line 24, spot-like voice guidance is performed from the four flat panel speakers 41 corresponding to the boarding position.

  Thus, in the tenth embodiment, when a user is detected by any one of the sensors 50, the boarding position of the platform H corresponding to at least one of the four doors 101 is specified, and the audio signal output unit By selecting the audio signal line 24 from 23a, it becomes possible to perform spot-like audio guidance from the four flat panel speakers 41 corresponding to the boarding position.

    Similarly, if no passenger is detected by any of the sensors 50, a boarding position where the user is not detected is specified, and therefore the audio signal line 24 from the audio signal output unit 23a is selected. Voice guidance is also possible only at the place where the user is detected.

  In addition, since the audio signal from the audio signal output unit 23a is amplified by the amplifier 42a on the guide information broadcasting device 40 side, the number of flat panel speakers 41 is limited as compared with the case where the high impedance amplifier 23 shown in FIG. Therefore, a large number of flat panel speakers 41 can be arranged even if the platform H of the station is wide and the number of the platforms H is large.

The D / A converter 43 converts a digital audio signal into an analog audio signal.

  The identification data given by the identification data giving unit 27 may be different for each flat panel speaker 41. However, as shown in FIG. 25, four pieces of identification data are provided corresponding to each of the four doors 101. Since the voice guidance from each of the arranged flat panel speakers 41 only needs to be substantially the same, the same identification data may be given to these four flat panel speakers.

  In such a configuration, as described above, when the user is detected by any one of the sensors 50 and the boarding position of the platform H of the station where the user is located is specified, the identification data adding unit 27 specifies the boarding position. Identification data corresponding to the flat panel speaker 41 corresponding to the boarding position is given.

  When the digital audio signal from the high impedance amplifier 23 is output to the audio signal line 24, the identification data included in the digital audio signal is converted into the guidance information broadcasting device by the data discriminating unit 44 on the guidance information broadcasting device 40 side. It is determined whether or not the flat panel speaker 41 in 40 is applicable.

  If applicable, the digital audio signal is converted into an analog audio signal to the D / A converter 43, and the four doors 101 corresponding to the boarding position where the passenger is detected by the sensor 50 are detected. Spot-like voice guidance is performed from the corresponding four flat panel speakers 41.

  Thus, in the eleventh embodiment, when a user is detected by any one of the sensors 50 and the boarding position of the platform H of the station where the user is located is specified, the identification data adding unit 27 specifies the boarding position. Since the identification data corresponding to the flat panel speaker 41 corresponding to the boarding position is given, it is possible to perform voice guidance only at the location corresponding to the boarding position where the user is detected.
