The present invention relates to a road guide apparatus for a visually impaired person, which not only senses the yellow color of Braille blocks installed on a road to guide the visually impaired person, but also reads information from an RFID tag to guide the visually impaired person. The road guide apparatus for a visually impaired person comprises a road sensing apparatus 10 including a handle, wheels attached to a main body 30 of the apparatus 10, a handle rod 20 fixed at the main body 30 via hinge 22, and a control unit 50 installed within the main body 30 and connected to a yellow color sensing unit 40 and a tag sensing unit 60. The yellow color sensing unit 40 senses the yellow color of a Braille block 2 or a yellow line and transmits a signal to the control unit 50. The tag sensing unit 60 senses a signal of the RFID tag installed on the road and transmits the signal to the control unit 50. The control unit 50 has a central processing unit 51 for processing signals, and an audio signal output unit 56 for transmitting information to a Bluetooth module 80 or an earphone 82 so as to be recognized by the visually impaired person. |
