Description

Apparatus of transmission to demand voice guidance and sound signal for vision sence disorder}

The present invention relates to a device for transmitting voice guidance and sound signal requests for the visually impaired, and more specifically, the voice that is pre-installed when a visually impaired person performs work, crosses or walks in a public place such as a crosswalk or a public office. The present invention relates to a transmitter for requesting a voice announcement and a sound signal in association with a guide or a sound signal device.

The public facilities used by the people who make up the general society are being developed and installed mainly for normal people, and the case of Korea, which is developing into an advanced society, cannot escape this frame. However, in developed countries such as the United States, public facilities are designed to be uncomfortable for the disabled as well as for the disabled, and the concept of the disabled for the disabled is changing. These days, the perception of the disabled in Korea is changing a lot, but it is not easy to find social welfare facilities that are concerned about the disabled in connection with real life in public places such as government offices. In particular, there are many inconveniences for the visually impaired people in real life due to the visual impairment.

Therefore, the installation of public facilities for the visually impaired one after another, Korean Patent Application Publication No. 1998-072020 (published date: October 26, 1998) (hereinafter, selected as the first application that has been filed and published by the applicant of the present application) Is a selection that is configured to cross the pedestrian crossing conveniently and safely for the visually impaired by overcoming this inconvenience.

1 and 2 together, the circuit configuration of the transmission device (TA) for requesting voice guidance and sound signals for the visually impaired (VD) is the vibration sensor 100, the main control unit 110 and the voice guide code generation The unit 120, the acoustic signal generating unit 130, the unique identification code setting unit 140, the encoder 150, the high frequency transmission unit 160 and the antenna ANT1. In addition, the main control unit 110 includes a reference value setting unit 111, a vibration detecting unit 112, a timer 113 and a code generation control unit 114, the switching switch (SW) is the main control in the vibration sensor 100 In order to switch the signal transmitted to the unit 110 is provided between the vibration sensor 100 and the main control unit 110.

While the visually impaired (VD) is walking in a public place, the vibration sensor 100 vibrates by detecting the movement of the visually impaired (VD). At this time, when the visually impaired (VD) stops movement, the vibration sensor 100 stops the operation.

The vibration detecting unit 112 of the main control unit 110 receives the vibration signal transmitted from the vibration sensor 100 and detects vibration based on the reference value set by the reference value setting unit 111. The reference value set by the reference value setting unit 111 is a preset value to determine whether the visually impaired person VD is walking or has stopped walking. The vibration detector 112 operates when the vibration signal sensed by the vibration sensor 100 is equal to or greater than the reference value set by the reference value setting unit 111, and sends the detection signal to the code generation controller 114. The code generation control unit 114 receiving the vibration detection signal from the vibration detection unit 112 generates the code generation control signal discretely according to the timing signal of the timer 113 and the voice guidance code generation unit 120. Transmission to the sound signal generator 130, respectively.

The voice guide code generator 120 receives the code generation control signal discretely transmitted from the code generation controller 114 of the main control unit 110 to generate a voice guide code and transmits the voice guide code to the encoder 150. The code generator 130 also generates a sound signal using the code generation control signal discretely transmitted from the code generation controller 114 like the voice guide code setting unit 120 and transmits the sound signal to the encoder 150.

At this time, the unique recognition code setting unit 140 outputs the corresponding recognition code in order to decode the voice guide code and the sound signal code from the encoder 150, the voice guide code generator 120 and the sound signal code generator 130 In the voice guidance code and the sound signal code generated by each.

The high frequency transmitter 160 receives the decoded voice guide code and the sound signal code from the encoder 150, amplifies the signal to a predetermined level, and transmits the same through the antenna ANT1, which is installed in the office SO as shown in FIG. Transmit to an antenna ANT2 of the receiving device RA or to an antenna of an acoustic signal (not shown) as mentioned in the selection. The high frequency transmitter 160 operates repeatedly by transmitting for 2 seconds and stopping for 3 seconds to extend the life of the battery built in the transmitter TA, and also interrupts time because continuous transmission is impossible under the Korean Radio Control Law. To transmit discretely.

The signal of the voice guidance code and the sound signal code received through the antenna ANT2 of the receiving device RA is processed by the selected voice guide device RA and transmitted to the speaker SP. The voice guide device RA ) Performs the role of sound signal as well as voice guide, so it can be installed in pedestrian crossing as well as selection. The visually impaired person (VD) will perform his / her job according to the sound signal broadcasting that can use voice guidance and pedestrian crossing to inform that the office (SO) is transmitted through the speaker (SP). At this time, the transmission device (TA) of the present invention on the wrist of the visually impaired (VD) can be modified to be attached to the waistband and can be used at any time where the selected voice guidance device (RA) is installed.

In addition, when the visually impaired person (VD) recognizes the voice guidance or sound signal broadcast from the voice guidance device (RA), the visually impaired person (VD) switches the switching switch (SW) of the transmitting device (TA) and repeats continuously. Not only can the voice guidance or sound signal be stopped, but the voice announcement or sound signal can be requested again.
