Blind guide

The invention relates to a blind guiding device, in particular to a blind guiding device capable of providing blind road information by using wireless transmission technology combined with a guiding device and an earphone.

In recent years, with the advancement of science and technology and the high development of humanities, people are paying more and more attention to social welfare. How to make people with reduced mobility have more convenient society has become an increasingly important issue. For visually impaired people, the completeness of blinding facilities is of great help to the convenience of blind people. The blind guide bricks have gradually been eliminated. The reason is that the latest visually impaired guidance concept is no longer seen. Guide blind brick is the only guiding tool. The visually impaired compatriots do not completely lose their visual function. They need a flat and comfortable sidewalk and can clearly distinguish the other sidewalks. For the blind all blind cells, the belt-shaped and unobstructed walking space is It is the best direction guide, and the bumpy guide bricks on the sidewalks are more likely to cause walking obstacles for the disabled.

Other common blinding devices have many shortcomings. The traditional guiding can only detect obstacles on the ground not far from the front; although the guide dogs can interact with the visually impaired, the feeding cost is high. Not affordable for the average person. Other common electronic guide blind devices, such as the use of pre-built landmarks with voice feedback systems, are more convenient than the previous guide blind devices, but they are unable to provide immediate analysis and analysis of road conditions.

Another example is an electronic guide blind assister that detects the environment and prompts the function of the obstacle. The global positioning system is used in conjunction with the voice system to inform the visually impaired of the road conditions. However, due to the need to include a variety of techniques for the guide aid, the high-function electronic guide aid is expensive, bulky, and power intensive, and does not meet the needs of the visually impaired.

Therefore, designing a blind guiding device, which can provide immediate analysis and return for road conditions, and reduce the economic burden of visually impaired persons, is easy to implement and light and easy to carry, and is a problem actively solved by those skilled in the art. One.

In view of the above-mentioned deficiencies, the inventors of the present invention have collected information, multi-assessed, and have accumulated many years of experience in the industry, designing and simulating the combination of technology products and guiding devices, and continuously designing and modifying. This blind guide.

The main object of the present invention is to provide a blind guiding device, which cooperates with the radio frequency identification technology, and when the blind person approaches, the reader carried by the blind device is connected with the guiding device and receives the instantaneous position and road condition information.

In order to achieve the above object, the present invention is achieved by the following technical means, wherein the blind guiding device of the present invention comprises: a guiding device comprising a wafer disposed at the intersection; a reader, which can be set On a device carried by a blind person; and a wireless headset connected to the reader via a wireless network; wherein the chip stores information about the location when the blind person approaches the guide When the device is blinded, the reader senses and reads the chip through a Radio Frequency Identification (RFID), and the reader transmits the read information to the wireless headset through the wireless network. The wireless headset plays the information so that the blind person knows where he is and decides where to go.

In a preferred embodiment, the guide blind device is a guide blind brick.

In a preferred embodiment, the guide blind device is a traffic light.

The above described objects, features, and advantages of the invention will be apparent from the description and appended claims

The present invention is further described in the following with reference to the embodiments of the present invention, but the embodiments are not intended to limit the scope of the present invention, and the description of the operation of the structure is not intended to limit the order of execution thereof. The recombined structure, which produces equal devices, is within the scope of the present invention.

Referring to FIG. 1, the present invention is a blind guiding device, comprising: a guiding device (1), a reader (21), and a wireless earphone (3).

The guide device (1) includes a wafer (12) disposed at the intersection, which may be a guide brick, a traffic light or a street light, but is not limited thereto. In the embodiment, the guide blind The device (1) is a guide blind brick. The wafer (12) internally stores information about the location.

The reader (21) can be disposed on a device (2) carried by a blind person (4), and the device (2) can be a mobile phone, a crutches or a wireless earphone (3), but is not limited thereto. The reader (21) can also be a standalone device. The reader (21) senses the chip (12) through a Radio Frequency Identification (RFID) and reads information on the chip (12). The principle of radio frequency identification is to use a reader (21) to emit radio waves, touch a corresponding chip (12) in the sensing range, generate current by electromagnetic induction, supply the chip (12) to operate and emit an electromagnetic wave response sensor. In this embodiment, the device (2) is a mobile phone.

The wireless headset (3) is mounted on the blind person (4) and coupled to the reader (21) via a wireless network. The wireless network can be Bluetooth or Bluetooth Low Energy (BLE). The advantage of Bluetooth connection is that it is easy to operate and low in power, suitable for short-distance wireless transmission. BLE can reduce power consumption and maintain longer operating time. In this embodiment, the wireless network is BLE.

With the above structure and composition design, the following is the use and operation of this creation:

Please also refer to FIG. 3, when a blind person (4) approaches a guide blind device (1), at this time, the reader (21) senses the wafer (12) of the guide blind device (1) through RFID. After driving the chip (12) by electromagnetic waves and reading the road information on the chip (12), the data is transmitted to the wireless earphone (3) through the BLE connection, and the wireless earphone (3) plays the road information so that The blind person (4) knows where he is and decides where to go.

It is worth mentioning that, as shown in FIG. 3 at the same time, the guiding device (1) may further comprise a wireless transmission device (13) and be connected with a road power supply system to obtain power, for example, a street lamp (5). And receiving the instant road condition by the wireless network and updating the information of the chip (12). After the chip (12) is powered, the signal can be actively transmitted for reading by the reader (21), and the signal transmission range is relatively wider than that of no power supply. By this arrangement, the guiding device (1) can reduce the power consumption of the reader (21) during use, and provide the latest road condition information to the blind person (4), such as whether there is an accident, construction, etc. in front. For the blind (4) reference to determine the direction of advancement.

Please refer to FIG. 4 , which is still another embodiment of the blind guiding device of the present invention, wherein the guiding device can be a street lamp ( 5 ) or a traffic light lamp, and can directly supply the power of the street lamp ( 5 ). The wafer (12) and the wireless transmission device (13) operate.

Referring to the entire drawings, in combination with the above, the blind guiding device of the present invention uses the wireless transmission technology combined with the earphone to transmit the instant road information through the earphone in the form of sound to assist the blind person to walk, thereby providing the user. Establish a virtual road scene to ensure the safety of walking.

Therefore, when using this creation, compared with the conventional technology, the following advantages exist: (1) The blind guide device of the present invention is relatively inexpensive. (2) The blind guide of the creation can make an immediate analysis and return according to the current road conditions.
