Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem that a conventional system adopts a method of listening to target audio guidance by causing a user to operate an installed device or a player carried with the user, there is a burden on the user to cause wrong operation or the like and in the conventional system, since it is difficult to deal with multiple languages, audio services can not provided for foreigners. <P>SOLUTION: An audio guidance system includes transmitters 4, 5, 6, 10 transmitting ID signals and a portable receiver 11 for receiving the ID signals and for reproducing target audio. When a user receives the ID signal transmitted from a target, audio guidance recorded in the portable receiver is automatically reproduced, thereby listening to the target audio guidance. Furthermore, a system is configured which is capable of easily providing multi-language audio guidance services. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

The present invention relates to an audio guide service by a portable audio reproduction receiver carried by a user for explaining an exhibit such as a museum or a museum. (Hereafter, exhibits that require audio explanations are called “objects”)

2. Description of the Related Art Conventionally, an unmanned guide device is a guide device description that provides information by image or sound by a user's operation, a system that listens to a guide broadcast with a receiver carried by the user, or an audio player equipped with a storage medium. A system is known in which a user carries a voice and provides a guidance voice by a user operation.

Japanese Laid-Open Patent Publication No. 2005-92483

There are techniques of [Patent Document 1] and [Patent Document 2] to solve the conventional voice guide. However, according to the technique of [Patent Document 1], since radio waves are used for information transmission, it is difficult to specify the range of use for an object, and a user who receives a guide voice other than the target object receives the user. May provide incorrect information.

According to the technique of [Patent Document 2], the reception area is specified in the same manner as [Patent Document 1]. In addition, since the audio information of the object is repeatedly broadcast, the user can listen to the guide audio from the middle. Forced.

In order to support these systems in multiple languages, it is necessary to assign a large number of channels, and there are problems such as a limit on the number of channels and a system in which a user performs an operation of selecting a receiving channel or a target guide voice. .

FIG. 1 shows an overhead view of the system of the present invention. The ID transmitters 4, 5, and 6 that transmit ID codes of wireless communication waves such as infrared rays at regular intervals to the exhibits (A, B, and C) 1 to 3, respectively, are received areas 7, 8, and 9, respectively. Install to be

When the portable receiver 11 carried by the user 10 enters the transmission area 7, the ID of the ID transmitter installed in the exhibit (A) is received, and this received ID becomes a trigger (start) signal to display the exhibit ( A) Voice guidance starts automatically.

When the user 10 finishes the audio guide of the exhibit (A) and enters the reception area of the next exhibit (B), the audio guide of the exhibit (B) starts automatically, and the user receives the portable receiver. You can listen to the audio guide of the exhibits one by one without 11 operations.

The receiver is provided with a function to prevent a user's erroneous operation by playing an operation guide of the receiver prompting the success or failure of the reproduction when entering the next reception area during the audio guide reproduction.

FIG. 2 shows a block diagram of each function equipped in the receiver. Digital audio data file that assigns a series of unique (single) ID codes (hereinafter referred to as IDs) and converts the audio guides of all the objects to be displayed into multiple languages, so that the audio guides can be used in many languages. Are stored in the audio data memory card 17 as follows.

A reception demodulation circuit 13 for receiving a radio signal transmitted from an object or an ID transmitter carried by a guide to be described later, and a CPU circuit 6 for searching and reproducing sound data corresponding to the received ID from the memory card data. And the receiver is a regenerative receiver. Therefore, the user can listen to the voice guide of the automatically reproduced object from the top (by the handset) by entering the reception area of the ID transmitted by the object.

Since it is easy to limit the receiving range of IDs that provide information by using infrared rays for communication media of IDs transmitted from the objects because of directivity and ease of blocking, Enabled the voice guidance system that avoids the interference.

The amount of guide voice data stored in the storage medium of this system depends on the number of objects and the number of languages. In recent years, large-capacity memory devices can be obtained at a low price. Since it is possible to store and manage audio data of up to 10 days, it is possible to provide audio guidance of exhibits for several days to the user.

The transmitter 2 intermittently transmits the voice guide ID of the object to the transmitting portable receiver by infrared communication, and the portable receiver automatically reproduces without any operation and can listen to the guide from the beginning, not from the middle. There are advantages that can be made.

For example, an ID transmitter using infrared rays installed on an object is intermittently transmitted at intervals of 1 second, so that power consumption is extremely small, and power supply by a battery or a solar power generation element is sufficient. Therefore, it is not necessary to supply power from the power line to the transmitter, and the transmitter can be reduced in size, so that the transmitter can be easily installed.

Shows an overhead view of one actual form of the system. Fig. 2 shows a block diagram of a portable receiver and a portable ID signal transmitter carried and operated by a guide and a signal transmission state of this system.

One embodiment of the present invention is shown in FIG. When the user enters the reception area of the transmitter installed on the object, the guide voice of the object is automatically reproduced from the portable receiver.

"Effect of the embodiment"
According to this embodiment, if a language to be reproduced is selected in advance from multilingual audio data stored in the mobile receiver, many foreign users can operate the guide voice without operating the mobile receiver. Can provide.

Claims (3)

FIG. 1 shows a system for performing audio guidance of exhibits. Each guidance object 1 in the exhibition hall is provided with a transmission device 2 that intermittently emits a code (ID) unique to the exhibition using radio waves or infrared rays. The user stores a storage medium 3 in which guide voices of all the exhibition objects are stored, a receiver 4 that receives and demodulates radio waves or infrared rays transmitted from a transmission device installed on the object, and a storage medium 3 A portable receiver that has a CPU 5 for selecting a guide voice and processing the operation switch 7 and an AD converter 6 for converting and reproducing voice data into voice is carried, and a user receives a transmitter installed on the object. A system is provided in which guidance voice is automatically played when entering a zone. FIG. 2 shows details of the user of the voice guidance system and the transmitter 2 installed on the object. The transmission circuit 8 of the transmission device includes an electronic circuit and a power source that intermittently transmit ID code pulses of several milliseconds assigned to an object at intervals of 1 second, for example. In addition, since the transmitting device operates with a minute electric power, the use of a battery eliminates the need for a power supply wire and reduces the size of the exhibit. In addition, if a photovoltaic power generation element is used, sufficient power can be obtained by lighting the exhibits, and battery replacement and power switches are not required. In facilities where this system has not been introduced, facilities where installation is not permitted, landscapes where buildings cannot be equipped with objects, buildings, etc., tour portable transmitters that send object IDs manually. The system operated by the conductor can provide voice guidance services in multiple languages.
