Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a visually impaired person guiding device for guiding visually impaired persons according to their purposes.

[0002]

[Prior art]

 In the past, this type of device consisted of a magnetic marker provided in the passage, a special white cane for detecting it, and a voice guidance device.The cane was equipped with a magnetic sensor and a small vibrator, and the magnetic sensor When a magnetic marker is detected, the cane vibrates and some voice guidance devices are activated. Further, as another guidance device, there is one that is composed of a small transmitter owned by the user and a voice sign guide device having a reception function, which is installed in a necessary place.

[0003]

[Problems to be solved by the device]

 However, in the above-described magnetic marker, since the magnetic sensor and the vibrator are incorporated in the cane, the user (visually impaired) is liable to bear the cost, and the battery is exhausted even in the small transmitter. In some cases, it is not possible to send and get accurate information (message). Further, in each of the above conventional examples, the user (visually impaired person) cannot obtain the unique information (service) by the specific identification number. The present invention has been made in view of the above problems, and the purpose thereof is to obtain information by a magnet, and to keep the distance between a moving body and a point block such as a snowy road where a transmitter does not require a power source. Another object of the present invention is to provide a visually impaired person guidance device that can transmit accurate information to visually impaired people even when they are far from each other.

[0004]

[Means for Solving the Problems]

 As means for solving the above-mentioned object, a moving body provided with a transmitter on the bottom of footwear or a tip of a cane, an external antenna provided inside or outside a Braille block, and a transmitter received from the external antenna are used. It consists of a control panel that operates various devices with a specific identification number, a magnet that is installed in the moving body, and a sensor that operates with magnets inside or outside the point block.

[0005]

[Action]

 Since the present invention has the above-mentioned means, when this is used, for example, the antenna main body is embedded below and around the point block and the control panel is installed in the vicinity of the point block. At the same time, a lead switch operated by a magnet attached to the tip of the cane is installed inside the point block. In this state, when the tip of the cane of a visually impaired person approaches the point block (30 cm to 1 m), the transmitter attached to the tip emits radio waves (for example, 312, When the power of 45 Mz) is caught, the power is automatically turned on, a specific identification number is transmitted from the internal antenna inside the transmitter, and received again by the external antenna, and the required information is sent through the speaker. In addition, even if the transmitter fails, the lead sensor is activated by the magnet and information is sent in the same way.

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The visual obstacle guidance device is composed of a moving body 1, an external antenna 4, a control panel 5, and a sensor 6. First, the moving body 1 is one in which a transmitter 3 is embedded in the tip of a cane 2. The transmitter 3 is composed of an IC chip 3a and an internal antenna 3b. The IC chip 3a is used for ID memory and communication. The necessary control circuits are all contained in one chip, and the internal antenna 3b uses a ferrite core to obtain an efficient communication effect. The ID memory has a capacity of 64 bits or more, and the reading distance is about 1 m. Further, a magnet 2a is attached to the tip side of the cane 2. The external antenna 4 is one in which an electric wire is wound around the lower surface of the dot-shaped block A, or an antenna main body 4a using a ferrite core is integrally provided, and the transmission / reception distance is about 1 m. Next, the control panel 5 has a transmitter circuit 5a for transmitting a radio wave (312, 45 Mz) for transmitting electricity (consumption power) to the transmitter 3 connected to the external antenna 4, and a transmitter circuit 5a in the transmitter 3. The specific identification number stored in a certain IC chip 3a is transmitted from the internal antenna 3b, and the receiving circuit 5b for receiving the identification number (specific frequency) and the received specific frequency (for example, 312, 45 MHz) detection circuit 5c, amplification circuit 5d that amplifies voltage value (power value), identification circuit 5e that checks modulation of a specific frequency (specific identification number), and output circuit that activates various devices. 5f. As the device, for example, a device which sends specific information to a visually impaired person by a voice synthesis circuit c and a speaker d can be considered. The sensor 6 is a reed switch operated by the magnet 2a, and is arranged in the dot block A.

When the above embodiment is used, when the visually impaired person approaches the point-like block A with the tip of the cane 2 (within 1 m), the radio wave (31 2, When the power of 45 Mz) is caught, the power is automatically turned on, the specific identification number is checked from the internal antenna 3b in the transmitter 3, and the information for each identification number (guidance information by the speaker d etc.) is provided. . The above example of use is effective when the distance between the point block A and the walking stick 2 is relatively large, for example, when the point block A is below snow. Also, the sensor 6 in the point block A can be operated by the magnet 2a, but this can obtain information by contacting the point block A. For example, when the transmitter 3 fails. Can also get information.

The external antenna 4 in the above embodiment may be provided at a position where the antenna body 4a is appropriately separated from the bottom surface of the Braille block A. As for various devices, in addition to voice guidance by speaker d, information is provided by using light and vibrator (contact), and in the case of transmitter 3 in particular, it is possible to identify by visually impaired persons (age, gender, etc.) by a specific identification number. Information can be provided (toilet guidance by gender, etc.).

[0009]

[Effect of device]

 As described above, the present invention has the following effects. With the above configuration, the transmitter of the mobile unit does not require a power source, so there is no trouble such as running out of batteries, and the distance between transmission and reception is long, so it is effective even during snowfall in winter. Also, by transmitting a specific identification number, it is possible to provide unique information for each visually impaired person. Furthermore, there is an effect that information can be obtained even if the transmitter fails due to the magnet.
