KR200283061Y1 - The sound traffic signals for a blind person - Google Patents

Abstract

The present invention relates to a guide sound and a voice guidance device for the visually impaired in the crosswalk. Existing visually impaired acoustic signals were installed in only one crosswalk or two pairs, and the sound contents and sound emission methods were the same. As a result, it has been difficult for the visually impaired to detect the direction to cross on the crosswalk.

The present invention aims to make the visually impaired people sense the crossing direction accurately by crossing the sound signal of the sound signal at the starting point and the expected arrival point on the crosswalk in two pairs.

Description

Sound signal device for blind people {The sound traffic signals for a blind person}

In order to allow the blind to cross the crosswalk safely,

Special 1998-28307 'Vibration walkway voice guidance device for the visually impaired' receiving guidance of the current location and the way to go by operation of the remote control, and 20-0176063 'Traffic signal for the visually impaired, which generates more cross-guided sound even when the red light is on. 'Guide Device', and the real 1996-000650 'Acoustic Beacon for the Visually Impaired,' which detects the north-south and east-west directions by changing the frequency and repeating form of the background sound.

However, in the conventional technology, the guide sound is radiated only at one place on the crosswalk, so that the direction of the starting point and the expected point of arrival cannot be guided, or it is installed in two sets so that the base sound frequency and the repetition form change the north and south directions. Detecting will only detect the direction of North and South, East and West. The present invention selects Korean or foreign language and selects A and B types so that the sound is emitted only from one sound signal at the same time or with a set of two sound signals so that the direction of the starting point and the expected arrival point can be accurately detected.

Existing visual signal system for the visually impaired was installed in only one crosswalk, so it was difficult to detect the cross direction, or even if two sound signals were installed on both sides of the crosswalk, the visually impaired person moved from the starting point of the crosswalk to the arrival point. As the radiation time of the light source coincides, the visually impaired person starts with the loudest sound signal near the starting point at the starting point of the crosswalk.

And the transversal direction should be taken while listening to the sound of the sound signal installed near the arrival point. Since the relatively small sound of the starting point and the expected arrival point is heard at the same time at the same time, it detects the radiation direction of the arrival point sound. There have been difficulties in determining the destination and moving.

Thus, in the present invention, the sound of the sound signal at the starting point and the expected arrival point on the crosswalk is partially coincident or with a time difference, so that the visually impaired person detects the crossing direction accurately by crossing the sound.

The present invention is a notice sound generating unit 100, the start sound generating unit 110, the flashing sound generating unit 120, the ground sound generating unit 130, the operation unit 200, the terminal plate 300, the speaker 400 A visually impaired sound signal group consisting of a power supply unit 500, a foreign language generator 600, a main control unit 700, and a clock pulse generator unit 800 are installed on both sides of a crosswalk;

The preliminary sound generating unit 100 stores the sound of "Please wait a moment" in the voice IC chip and generates the sound through the speaker.

The start sound generator 110 stores the sound of the melody “ding dong deng” and the message contents “green light is turned on” and “it may be crossed” in the voice IC chip and generates the sound simultaneously or through a parallax through a speaker.

The blinking sound generating unit 120 stores the sound of "Hazard, please wait for the next signal" in the voice IC chip and generates the sound simultaneously or with a time difference through the speaker.

The operation unit 200 operates the sound signal for the visually impaired through the operation buttons and the remote control, and emits the sound of the warning sound "Please wait" by the operation unit.

Terminal plate 300 omits the notice sound (when the green light of the pedestrian crossing light is turned on immediately when the operation part and the notice sound generation part are omitted, the start sound generation part is operated.) Selection, AB type (A type, B type) Select the type to make two types into one set.) Selection, language selection There are Korean and foreign language terminal, and it is operated by the administrator.

The foreign language generator 600 stores messages in Japanese, Chinese, English, and German, "You may skip" and "Please wait for the next signal."

The power supply unit 500 is installed in parallel with the power line of the pedestrian crossing pedestrian light, and turns on the green light when one of the first lights of the green light and the red light turns off through the relay 1 and the green light relay 2 of the red light power supply. The sound signal device for visually-impaired persons is operated normally even in the event of one disconnection of the pedestrian lamp.

The main control unit 700 controls the overall sound signal device for the visually impaired.

The clock pulse generator 800 selects A and B types and provides time pulses for adjusting the time difference as the sound is emitted at the same time or with a time difference in two sets.

This audio signal for visually impaired person who installs 2 sets of A and B as a pair of visually impaired people such as pedestrian crossing walks is sounded by operation of operation button or operation of remote controller as shown in FIG. The notice sound of the generation unit 100 will be a guide broadcast of "Please wait a moment", and if you want to select the way to operate unconditionally when the green light turns on without the operation of the remote control or button type, the notice sound in the terminal board 300 If the selection is omitted, the operation unit 200, the notice sound generating unit 100 is omitted.

When the green light is turned on, the sound of the melody "ding dong dang" and the message content "green light" is emitted from the start sound generator 110 at the same time at the sound signals A and B, and then "crosses" only at the A sound signal. Only the sound of is emitted, followed by only the sound of "Best to skip" from the B sound signal, and then the background sound is a frequency of 800 to 900 Hz (aka cricket). Signals alternately emit sound. That is, if the A sound signal emits the ground sound for 1 second, after 0.5 seconds, the B sound signal alternates the ground sound for 1 second to alternately emit the ground sound to guide the arrival point. When the green flashing signal of the pedestrian light flashes, the A and B sound signals are emitted by the flashing sound generator at the same time, and the A and B sound signals are alternately emitted after the message "Please wait for the next signal." Exit when the pedestrian light turns red.

In addition, when the language is set to Korean by the terminal board 300, the above-described control is performed. However, when the language is selected as a foreign language, the operation sound of the operation unit as shown in FIG. The sound is emitted in order of Japanese, Chinese, and German, but even if the green light on the pedestrian light turns on during the acoustic radiation, the start sound is emitted immediately.A, B sound signal at the same time, the melody "Ding dong deng" at the same time in Korean, Followed by a "sound is ok" sound in English only on the A sound signal, followed by a "sense good" sound in Japanese on the B sound signal only, followed by a "sound is good" in Chinese on the A sound signal only Is emitted followed by the "Best crossing" sound in German only on the B sound signal and flashing green light A and B sound signal at the same time is emitted in Korean at the same time sound "Hazard, please wait for the next signal" followed by A sound signal only in English, "Hazard, please wait for the next signal". After the sound is emitted in English "Please wait for the next signal" A and B sound signals followed by the sound in Korean at the same time "Danger, please wait for the next signal" sound after the sound is emitted After the "Please wait for the signal" sound is emitted, only the B sound signal will emit the sound "Please wait for the next signal" in Japanese, followed by the A and B sound signals at the same time in Korean. After the radiation, only the A sound signal is emitted in Chinese, "Please wait for the next signal." Only the audio signal is emitted in Chinese, "Please wait for the next signal". Then, A and B sound signals are emitted in Korean at the same time. Please wait for the next signal ". The sound is emitted in B sound signal only in German and ends when the" Please wait for the next signal "sound is emitted and the red light is on.

The message and melody of the notice sound generator, the start sound generator, the flashing sound generator, the background sound generator, and the foreign language generator can be changed with the IC voice chip memorized in each country's language.

When the visually impaired person walks crosswalk through the above control, it is possible to traverse the starting point to the arrival point without losing the direction, and when the sound signal ends early compared to the equalization period, the sound corresponding to the equalization is repeated. A sound signal device for the visually impaired having a main control unit that controls to switch to the next sound signal immediately after the equalization period and to terminate the message even when the equalization period is shorter than the sound signal.

To solve the problem of the current visually impaired audio signal that the sound at the starting point is relatively louder when the same sound is emitted at the same time even if it is installed in only one crosswalk or two sets, It emits sound only from one coincidence or only one sound signal to recognize the direction of departure point and expected arrival point, and to safely cross it. It is an acoustic signal device for visually impaired people with crosswalks that can be selected.
