Description

  The present invention relates to a voice guidance system that can listen to the content of an exhibition in front of the eyes or an exhibition that moves in front of the eyes without interference, and in particular, in front of the eyes in various sightseeing or museums. The present invention relates to a voice guidance system that can listen to each content of an exhibit moving in front of the eyes, such as a stationary exhibit and an event queue, without interference.

  Most of the conventional voice guidance systems are related to stationary exhibits in museums or expositions, and a special device developed exclusively for voice guidance has been used.

  An example of a voice guidance system related to a stationary exhibit is shown in Patent Document 1. In Patent Document 1, a spectator holds a portable automatic guidance device that stores data for viewing an exhibit, and receives unique identification data transmitted from the exhibit, thereby providing appreciation data corresponding to the identification data. It is stated that you can hear (contents of the exhibit).

  The voice data supply method disclosed in Patent Document 2 is a card-type voice guidance device in which a card-type voice guidance device carrier displays an explanation of an exhibition from a voice data wireless transmitter installed at a specific location when passing through a specific area. It is described that the apparatus automatically supplies wirelessly to the apparatus, and that the audience can always listen to the wirelessly supplied exhibition description from the beginning.

  In the automatic video / audio guide device disclosed in Patent Document 3, the remote control device attached to the exhibit senses the proximity of the portable random access video / audio playback device held by the audience, and the contents of the exhibit are displayed. It is transmitted to the playback device, and it is described that the audience holding the playback device can listen to the content.

  The audio guide reproduction apparatus disclosed in Patent Document 4 is for the audience to select and listen to audio data related to exhibits recorded in digital form. If the selection is wrong, incorrect audio data will be heard.

  In the tourist guidance information system shown in Patent Document 5, the tourist bus unit receives and stores tourist guide information by radio wave beacons transmitted from tourist spots, and the handy terminal is based on the tourist guide information stored in the tourist bus unit. It is described that the passenger can listen by selecting the contents of the tourist spot.

  An information providing method disclosed in Patent Document 6 is related to a moving exhibit, which is an information transmission terminal for short-distance communication installed in an exhibit or the like, and is wireless based on the Bluetooth (registered trademark) standard. By using what communicates, the contents of the exhibit can be known by the mobile phone held by the audience.

Japanese Patent No. 2765703 Japanese Patent Laid-Open No. 5-282542 Registered Utility Model No. 3015155 JP-A-11-143419 JP 2000-29942 A JP 2003-87188 A

  In the above-described conventional voice guidance system used for explaining stationary or moving exhibits, a special transmitter and / or receiver is required, including the case of using a mobile phone. In particular, for the explanation of the contents transmitted wirelessly from the exhibits, special receivers are used, and the number of receivers is usually limited. The number is limited. In particular, in general, there are many unspecified audiences who observe an event matrix, and there is a problem that it is difficult to obtain a special receiver.

  There is also a system in which a general mobile phone device is used without using the special receiver as described above, and the explanation and the like can be heard by sending a signal from the exhibit. However, the mobile phone has a problem that power consumption is large and it cannot be used for a long time. Further, since the receivable distance of the system is about 10 m, there is a problem that some audiences cannot be heard when the event matrix is longer than that.

  In the above-described conventional system, there is a possibility that interference may occur in the description of adjacent exhibits when the exhibits approach, and there is a problem that the prevention technology is not always clearly shown.

  Therefore, the object of the present invention is to solve the above-mentioned problems, and withstands long-term use without using a specially designed transmitter and a special receiver that is difficult to obtain. To provide a voice guidance system that can listen to explanations of exhibits even if the event queue is longer than 10 m, and does not cause interference in the explanation of neighboring exhibits even when the exhibits are approaching. It is in.

The voice guidance system of the present invention is a voice guidance system in a place where stationary exhibits are arranged, and each exhibition is performed at the same frequency from an FM (frequency modulation) transmitter installed at a predetermined position of each exhibit. When information about an exhibit is transmitted and the receiver side approaches a predetermined distance from the exhibit, the information about the exhibit is sent to the same receiver on the receiver side without interfering with information regarding other exhibits. It is characterized by listening.

  The voice guidance system of the present invention is a voice guidance system for exhibits moving in a matrix, and information on each exhibit at the same frequency from an FM (frequency modulation) transmitter installed at a predetermined position of each exhibit. When one exhibit in the queue approaches the audience, the receiver can listen to the information about the exhibit at the same receiver on the receiver side without interfering with the information about the surrounding exhibits. To do.

  Here, in the voice guidance system of the present invention, the predetermined position where the FM (frequency modulation) transmitter is installed is near the center of the exhibit, and the FM transmitter can be freely adjusted to a certain output or less. .

  Here, in the voice guidance system of the present invention, the predetermined position where the FM (frequency modulation) transmitter is installed is an end of the exhibit, and the antenna of the FM (frequency modulation) transmitter has directivity. It can have.

  Here, in the voice guidance system of the present invention, the antenna of the FM (frequency modulation) transmitter can be extended and retracted.

  According to the voice guidance system of the present invention, it can be applied not only to stationary exhibits but also to explanations of moving exhibits. The receiver (reproducing device) held by the audience may be a general FM receiver or an inexpensive auto-scan type thin FM receiver that has been recently marketed. The transmitter may be a commercially available FM transmitter. Therefore, there is an effect that it is possible to provide a voice guidance system that can withstand long-term use without using a specially designed transmitter and a special receiver that is difficult to obtain. The audible range can be adjusted by changing the transmitting antenna characteristics depending on the position of the transmitter. For stationary exhibits, the audible range can be adjusted according to the spread of the audience around the exhibit, and for moving exhibits, such as event queues, audible depending on the length of the queue It is possible to adjust the range. For this reason, a voice guidance system that can listen to explanations of exhibits even if the event queue is longer than 10 m and does not cause interference in the explanation of adjacent exhibits even when the exhibits are approaching. There is an effect that it can be provided.

  First, an outline of the voice guidance system of the present invention will be described, and then specific examples and experimental results will be described in detail with reference to the drawings.

  In the description of a stationary exhibit such as a work of art, generally, an explanatory note of the exhibit relating to its origin and contents is arranged on the side of the exhibit. However, elderly people with poor eyes are difficult to interpret fine characters and the display effect is halved. In such a case, if a small transmitter (FM transmitter) with a playback device in the voice guidance system of the present invention is placed behind the explanatory text, etc. (predetermined position), the voice of the present invention distributed at the reception is provided. Listen to the card-type auto-scan FM radio etc. (receiver) in the guidance system with earphones and enjoy the normal FM broadcast when you are away from the exhibit. Information on each exhibit) can be heard. In this case, it is desirable that the transmitter has a small output with a radio wave reach of 5 m (predetermined distance) or less. At this time, even if the distance to the adjacent exhibit is about 1 m, the explanation of the exhibit can be heard without interference. In the voice guidance system of the present invention, as a characteristic of frequency modulation (FM), the stronger one is selected (masking effect) if the same carrier frequency is used to prevent interference.

  The present invention can also be used when the exhibit moves. That is, for example, “Nepta”, a typical summer festival in the Tsugaru region, will have “Neputa” as a total of 60 “participate”. However, it is difficult for all these units to “run” overnight, and usually about 30 “Nepta” “run” every night. These “Neputa” are produced independently by each neighborhood association or company, and various stories are hidden in the selection and creation of the pictures. In addition, when and which “Neputa” will take part is arbitrary and is not particularly determined. The contents of each “Neputa” are detailed in pamphlets sold throughout the venue, but it is almost impossible to read the contents while viewing each “Neputa” that actually passes in front of you. . On the other hand, the announcer explains the contents of each “Neputa” through a speaker in a specific spot for such a situation, but such an explanation cannot be given in all the places of the audience seat with a total length of about 2000 m.

  At the time as described above, the audience can enjoy the deeper contents of the festival using the voice guidance system of the present invention. In other words, “Neputa” is placed at the center of each matrix. The “Nepta” is equipped with a small transmitter (FM transmitter) with the above-mentioned playback device, and the contents of its own “Neputa” (each exhibit) Information on (about) is sent. The length of the description should be such that it repeats at least twice while the matrix passes in front of the audience. This is because the portion missed in the first explanation can be heard in the second explanation. Therefore, the length of the description is proportional to the length of the matrix. In addition, it is preferable that the effective reach of radio waves transmitted from the transmitter is (matrix length / 2) or more, ideally about 1.5 × (matrix length / 2). Preferably there is. In any case, it is preferable that the effective range of radio waves be equal to or longer than the length of the matrix (exhibit).

  The card-type auto-scan FM radio (receiver) held by the audience may be a normal FM radio that the audience brings from home, or can be sold at a low price around the venue. Recently, a thin auto-scan FM radio with earphones is available for one coin (about 500 yen). Therefore, the organizers of the venue can sell it as a specially designed radio, and the specially designed radio can be used as a souvenir and can be used as a normal radio after the festival. is there.

Experiment 1. Stationary exhibits (transmitters A and B) and recipients (experimenter A)
Two transmitters A and B with the above playback devices are placed 20 m apart from each other at positions 1 and 2 (both not shown), and the transmission frequency is set to the same frequency 78 MHz (same frequency). Sends music, and transmitter B sends readings. When the experimenter who possesses the FM radio walks in a straight line from the location 1 of the transmitter A that is transmitting music to the location 2 of the transmitter B, it reads from the music at an intermediate point, that is, at a point 10 m from both transmitters. After that, it did not change to the position of Transmitter B that sent readings.

Experiment 2.
In the above-described state, the same experiment was performed by setting the output of the transmitter B that transmits readings in half. As a result, it was confirmed that the switching place from music to reading moved to the transmitter B side which transmits about 5 m reading. That is, it has been found that the switching point can be changed by adjusting the output.

Experiment 3. Moving exhibits (Otsuka with transmitter A, Sakai who owns transmitter B) and recipients (experimenter A)
Next, the two transmitters A and B equipped with the playback devices were held by the two members B and B, respectively, and were placed at positions 1 and 2 20 m apart from each other. Each transmission frequency is set to 78 MHz, music is transmitted from the transmitter A owned by the second party, and reading is transmitted from the transmitter B owned by the second person. The experimenter who owns the FM radio is listening to the reading at the position 2 of the kite that owns the transmitter B. Along with the signal from the experimenter A, the second and the second are moving away from the experimenter A in the direction of the experimenter A, and the second is collinear with the positions 1 and 2 and at the same speed. At this time, the experimenter A confirmed that the reading changed from the reading to the music at a point near the experimenter A about 10m.

Experiment 4.
Two transmitters A and B with a playback device are placed at positions 1 and 2 20 m apart from each other, the transmission frequency is set to the same frequency of 78 MHz, music is transmitted from transmitter A, and from transmitter B Sending recitations. Each transmitter A and B is equipped with the same directional antenna, and the direction of the transmitter A is opposite to the direction of the transmitter B with respect to the antenna of the transmitter A, and the direction of the transmitter B is directed to the direction of the transmitter A. . When the experimenter who owns the auto-scan mini-radio walks in a straight line from the location 1 of the transmitter A where music is being transmitted to the location 2 of the transmitter B, the music is about 1 meter from the transmitter A to the location B. The content changed from reading to reading and did not change to the position of transmitter B.

Experiment 5.
Two transmitters A and B with a playback device are placed at positions 1 and 2 20 m apart from each other, the transmission frequency is set to the same frequency of 78 MHz, music is transmitted from transmitter A, and from transmitter B Sending recitations. In addition, the length of the antenna of the transmitter B is set to be half the length of the antenna of the transmitter A. When the experimenter A with FM radio walks linearly from transmitter 1 to transmitter 2 where music is being transmitted, the content changes from reading to reading at 15m, and then readings are sent. Did not change to position 2 of transmitter B.

Experiment 6.
The voice guidance system of the present invention was actually tested at Hirosaki Park. FIG. 1 is a map showing the situation in which Experiment 6 was performed. Prepare three transmitters A, B, and C of the same type with a playback device, and place transmitter A at Hirosaki Castle castle tower position 1 and transmitter B at follower gate position 2 (on the gate: predetermined position). The transmitter C was placed at the tourist building position 3 on the Hirosaki Park side. As for transmitters A, B, and C, transmitter A sends a description of the castle tower, transmitter B sends a description of Otemon, and transmitter C sends a description of the Tsugaru paintings that are displayed in the tourist hall. In FIG. 1, the experimenter A possessed FM radio and moved along the route of arrow X. In the arrow X route, at point P in FIG. 1, the explanation switches from the description of the castle tower (explanation at transmitter A) to the explanation at Otemon (explanation at transmitter B), and the explanation at point Q is the explanation of Otemon. (Description in transmitter B) switches to description of Tsugaru coating (explanation in transmitter C), and the explanation at the point R changes from description of Tsugaru coating (explanation in transmitter C) to description of Otsumon (explanation in transmitter B) It was confirmed that it switched. Interference at the switching points, P, Q, and R points was not observed. Judging from FIG. 1, the radio wave of the transmitter A has reached a considerable distance, which is presumably because there were few obstacles to the arrival point because the transmitter was placed in a high altitude castle tower. The transmitter A or the like is arranged in the approximate center (near the center) of the exhibit, and the effective range of radio waves can be adjusted by adjusting the output of the transmitter A or the like freely below a certain output. Alternatively, the effective range of radio waves can be adjusted by arranging a transmitter A or the like having a directional antenna at the end of the exhibit. In the above case, the effective range of radio waves can be adjusted by making the antenna such as transmitter A extendable.

  As described above, according to the first embodiment of the present invention, information on each exhibit can be obtained at the same frequency from the FM transmitter A or the like installed at a predetermined position of each exhibit within the place where the stationary exhibit is arranged. When the receiver side approaches a predetermined distance with respect to the exhibit, the information on the exhibit can be heard at the same receiver on the receiver side without interfering with information on other exhibits. it can. Therefore, without using a specially designed transmitter and a special receiver that is difficult to obtain, it can withstand long-term use and listen to explanations of exhibits, and it can also explain adjacent exhibits. It is possible to provide a voice guidance system in which interference does not occur.

  Furthermore, according to Embodiment 1 of the present invention, there is provided a voice guidance system for exhibits that move in a matrix, and each exhibit has the same frequency from an FM transmitter A or the like installed at a predetermined position of each exhibit. When information is transmitted and one exhibit in the queue approaches the audience, information on the exhibit can be heard at the same receiver on the receiver side without interfering with information on surrounding exhibits. . Therefore, listen to the explanation of the exhibit even if it is a long event queue that can withstand long use and exceeds 10 m without using specially designed transmitters and special receivers that are difficult to obtain In addition, it is possible to provide a voice guidance system in which interference does not occur in the explanation of adjacent exhibits even when the exhibits are close to each other.

  As an application example of the present invention, the present invention can be applied not only to stationary exhibits in museums, expositions, etc., but also to systems that explain the contents of the exhibits to the audience and the like regarding moving exhibits such as event queues. This is a system that can be used by an unspecified number of people in using ordinary FM radio without using a special receiver, and can be used without any problem of interference in the explanation of adjacent exhibits. Therefore, the field of use is not limited to the above, and can be used for explanations of sightseeing spots in sightseeing spots or explanations of appearance teams at festivals and the like, and can be applied to various fields.

It is a map which shows the condition where Experiment 6 of the voice guidance system of this invention was performed.
