Description

Walk guide system using RFID system {Walk Guide system for using Radio Frequency Identification System}

The present invention relates to a technology for ensuring the right of movement of the visually impaired by using an RFID system.

In general, RFID stands for Radio Frequency Identification and is a kind of automatic recognition technology.

The tag attached to the product contains information about the entire process of production, distribution, storage, and consumption, and has its own antenna, which allows the reader to read this information and integrate it with the satellite or Speak activity, or chip.

Non-contact reading is possible using data stored in Tag, Label, Card, etc.

Semiconductor chips and antennas send information wirelessly from a few meters to tens of meters, and the reader receives this signal, decodes the product information, and sends it to a computer.

In RFID system, RFID tag can be divided into active type requiring active power and passive type operated by reader without supplying power directly from inside or outside.

Active type has the advantage of reducing the power required of the reader and the recognition distance from the reader. However, since it requires, it is limited by and has a disadvantage that it is more expensive than passive type.

On the other hand, the passive type is very light and cheaper than the active type and can be used semi-permanently. However, the passive type has a shorter recognition distance and consumes much more power in the reader.

In addition, the RFID reader of the RFID system has an electronic circuit part that transmits and receives a radio wave toward a tag. In the reader, it is stored in memory, which is a storage device, and converts the signal from the tag, verifies the signal of the data, and has a transmission function.
