The present invention is a visually impaired gait signal transmission and reception system for receiving the information about the crosswalk and the surrounding situation that is wirelessly output when passing the crosswalk and output through the earphone or speaker It is about.

In more detail, at a traffic light post that is built on both edges of a pedestrian crossing and adjacent sidewalks and is equipped with a traffic light, a transmission device in which information such as a traffic light of the pedestrian crossing and its position and direction is inputted and transmitted is outputted. It provides a walk-in signal transmission and reception system for the visually impaired, which allows the visually impaired person who is within the transmission range of the device to receive wirelessly by the receiving device carrying various information output from the transmission device and listen to the earphone or output through the speaker. I will.

Conventionally, the auxiliary apparatus for the visually-impaired person installed in the crosswalk includes "the device for transmitting voice guidance and sound signal request for the visually impaired" in Korean Utility Model Registration No. 20-193111, and the utility model registration No. 20-283061 in " Acoustic signal device for the visually impaired, "Pedestrian crossing voice signal button device for visually impaired" No. 10-1996-25273, and "Radio propagation method" in Publication No. 10-2005-80187 Traffic weak crosswalk safety support system and method thereof, and Patent No. 10-194064 "Traffic signal guide device for visually impaired and its control method" are known.

Utility Model Registration No. 20-193111, "Voice Guidance and Sound Signal Request Transmitter for Visually Impaired Persons," Utility Model Registration No. 20-283061, "Audio Signal Device for Visually Impaired Persons," and Korean Patent Application Publication No. 10-1996 -25273, "Pedestrian crosswalk voice signal button device for visually impaired" and "Public Weak Crosswalk Safety Support System and Method Using Radio Frequency Identification Method" of Publication No. 10-2005-80187 When a switch installed in a traffic light is operated or a person with a disability is positioned on a crosswalk, the electronic device stored inside the traffic light broadcasts the signal information of the traffic light and the direction of the surroundings through a speaker installed in the traffic light.

However, since this system broadcasts the signal system and the surrounding information through the speaker, there is a problem that the visually impaired person cannot easily hear the information as the broadcasting contents are mixed with the surrounding noise, and the blind person has to switch the posts of the signal lamps. There is a problem that can not be found easily do not utilize smoothly.

In addition, Patent Registration No. 10-194064, "Traffic signal guide device for the visually impaired device and its control method", enters the direction that the visually impaired person wants to proceed by using a transmission unit for transmitting a radio signal, the transmission unit is entered It modulates the direction into a radio signal and transmits it to the receiving unit, and the receiving unit receives and demodulates the information of the transmitted traveling direction, and the auxiliary direction information and the direction signal of the signal signal for the traveling direction and the traffic information of the corresponding direction signal. Compared to output the voice signal, the visually impaired to output the traffic signal to the voice.

However, this is a problem that even if the visually impaired person carries the transmission unit, the noise is excessively generated on the side of the road, so it is difficult to input the direction of movement because it is scattered and busy, and even if the normal person uses the transmission unit, this also can be utilized smoothly. There is no problem, and since the traffic information output through the speaker is mixed with the surrounding noise, the visually impaired person cannot easily listen to the traffic information, and there is a problem that the utilization is significantly reduced.

The present invention is to provide an improved walk-in sound transmission and reception system for the visually impaired to solve the above problems.

According to the present invention, a traffic light post, which is built on both edges of a sidewalk and adjacent to a crosswalk and is provided with a traffic light, is provided with a transmission device in which information such as the traffic light and the position and direction of the crosswalk is input and transmitted, and the transmission of the transmission device. The purpose of the present invention is to provide a walk-in signal transmission / reception system for the visually impaired, which enables the visually impaired to receive wirelessly by the receiving device carrying various information output from the transmitting device and to listen to the earphone or output through the speaker. There is this.

Another object of the present invention, when the visually impaired person carrying a wireless receiver near the traffic light installed in the crosswalk enters the transmission device installed in the traffic light post to detect (detect) it, the current position, the visually impaired people and traffic lights Wirelessly outputting information such as a separation distance and an entry direction to a pedestrian crossing, a direction straight ahead and a rearward, a position and a traveling direction across the pedestrian crossing; The wireless receiver carried by the visually impaired person outputs various information transmitted from the transmitter and outputs it through the earphone or the speaker which the visually impaired person attaches to the ear. The purpose of the present invention is to provide a walking beep transmission and reception system for the visually impaired, which can be acquired more efficiently, easily and naturally.

The above and other objects of the present invention,
