Description

Technical Field [0001] The present invention relates to a cross-

The present invention relates to a crosswalk information providing system for a visually impaired person, and more particularly, to a system for providing a crosswalk information providing system for a visually impaired person, The present invention relates to a system for providing crosswalk information for the visually impaired, which provides crosswalk information and sound file corresponding to terminal information through a server and a broadband mobile communication and guides the crosswalk to the blind.

Generally, a crosswalk is equipped with an acoustic signaling device to assist the visually impaired in safe use. The acoustic signaler is a facility that allows the visually impaired to walk through the crosswalk safely without the aid of others. The voice signal generated by the acoustic signaling device is divided into a signal indicating the position of the pedestrian crossing and a signal indicating the lighting of the green light.

For example, the acoustic signaler allows the position of the pedestrian crossing to be recognized by Bach's G major Minute melody. When the green light is turned on, a woman's voice is output at the crosswalk on the right side of the intersection, and a male voice is output from the crosswalk on the left to inform the passable state. Such a voice signal is output when a button installed on a sound signaler or a button of a remote control owned by a visually impaired person is pressed. When the gait light is red, a voice saying "Please wait. It is good to cross the street. "With the sound of a cricket sound, it induces a safe crosswalk.

However, such a sound signal system has some problems.

First, there is a problem that the button installed in the sound signal is hard to find by the visually impaired. Also, even if the blind person does not use it, the acoustic signal is output to inform the position of the crosswalk, which may act as noise to other people. In addition, there is a management inconvenience in that a manager is dispatched to a field to adjust the volume of an acoustic signal device when a complaint is caused by a noise inconvenience.

Furthermore, there are problems in that sound source files for generating sound signals are not unified, managing dispatching personnel to update sound source files, maintenance of devices, and the like, while managing sound signals in accordance with local governments .

Meanwhile, Korean Patent Laid-Open Publication No. 10-2016-0108674 proposes an acoustic guidance system for a visually impaired and an operation method thereof. This prior art document discloses a configuration in which an acoustic guidance device and a portable communication device of a visually impaired person communicate using Bluetooth and a sound signal output of an acoustic guidance device is activated by the selection of a visually impaired person.

However, as the acoustic signal is output from the acoustic guidance apparatus, there still exists a problem that the noise acts on other people as described above, and management such as updating the sound source file is still required.

At this time, the current position information measured by the GPS module 136 of the user terminal 100 may be transmitted together. Generally, the GPS module receives a signal from a satellite, so that a slight error may occur in the position information. When the user terminal 100 enters the communication radius of the local signal unit 300, the distance to the local signal unit 300 can be recognized. Accordingly, by combining the relative distance with the local signal unit 300 and the absolute position included in the terminal information of the local signal unit 300, the current position measured by the GPS module 136 is corrected, You can check the location. When the traffic guidance message is generated at the user terminal 100 in the future, the traffic guidance based on the corrected position information can prevent the visually impaired person 110 from deviating from the safe traffic route on the pedestrian crossing.
