1 is a diagram illustrating a traffic light control system including an acoustic signaler according to an embodiment of the present disclosure;

Referring to Fig. 1, the traffic light control system includes an acoustic signaler 100, a traffic light controller 10, a pedestrian traffic light 20-1 and a traffic signal light 20-2.

The acoustic signaling device 100 may be a voice guidance device for a visually impaired person. The acoustic signaling device 100 is one of the facilities for the visually impaired and is installed on a support to which a traffic light or a traffic light of a pedestrian crossing is connected so as to provide information about the availability of the pedestrian crossing and information about the unique location where the pedestrian crossing is located have. Specifically, the sound signal generator 100 is information on the transversal section, and it is determined whether the red light of the crosswalk is lit, whether the green light is on, how much time is left until the green light is turned on, And how much time has elapsed before the user can be informed to the user. In addition, the sound signal generator 100 can provide information about the unique position, such as a name of a current position, a usage guide, directions starting from the current position, guidance of the next position, and the like to the user as a voice. The sound signal generator 100 can be operated by an input signal of a remote controller (not shown).

The remote control is one of the convenience devices possessed by the visually impaired and allows the visually impaired on the move to receive guidance, location and facilities guidance on the crossing. Specifically, a blind person on the road can receive guidance from the audio signal machine 100 for the traversing ability by pressing a button provided on the remote controller in the vicinity of the pedestrian crossing. In addition, the blind who is on the move can receive the guidance about the unique position where the sound signal transmitter 100 is installed from the sound signal transmitter 100 by pressing the button provided on the remote controller.

On the other hand, the acoustic signaling device 100 may include a pedestrian activation signal function. The pedestrian activation signal function means that the green traffic light is activated only when the pedestrian signal button is pressed in a predetermined case. For example, the vehicle can be used in a night time zone where vehicle traffic is likely to occur, or in a place where vehicle traffic is low. On the other hand, the traffic light control system can be implemented in such a manner that even if the pedestrian signal button is depressed, the pedestrian signal is not operated immediately but a certain signal period is required.

The traffic light controller 10 is installed at an intersection and a transverse road and controls a traffic light. The traffic light controller 10 can have independent crossroads control, interlinked control of an arterial road, and a function of being connected to a central computer. The traffic light controller 10 may include intelligent control devices, communication devices, contradictory detection devices, vehicle detector terminal boards, and registry switches using a microprocessor with a waterproof housing. The signal lamp controller 10 also includes a memory (e.g., ROM) having a program for signal control and a memory (e.g., RAM) for storing data for executing a program, Lt; RTI ID = 0.0 > and / or < / RTI > electrical characteristics. Further, the control program can be designed so that the correction can be easily stored in the EPROM, and the function can be easily supplemented or modified.

In addition, the traffic light controller 10 includes a traffic-sensitive control (Actuated Control) system in which the signal time per direction is changed according to the information input from the vehicle detector installed at the intersection, a TOD (Time Of Day) control method, a central control (on-line control) method by a central computer, and a signal control function such as a coordination control method capable of controlling an adjacent intersection and an interlocking signal have.

The pedestrian signal lamp 20-1 is installed on a pedestrian crossing to indicate whether a pedestrian is crossing, and may generally include a red light and a green light. The vehicle signal lamp 20-2 is a device installed on the road to notify whether the vehicle is proceeding or stopping, and may generally include a red light, a green light, a yellow light, etc. The red light, the green light, the yellow light, and the like may be embodied as light sources that emit light of respective colors. Alternatively, red light, green light, yellow light, and the like may be implemented using a light source that outputs light of the same color and a cover of each color.

FIG. 2 is a diagram for explaining a system for controlling an Internet-based acoustic signal transmitter according to an embodiment of the present disclosure.

Referring to FIG. 2, a plurality of signal lamps and a plurality of sound signal devices 100-1, 100-2, 100-3, 100-4, 100-5, 100-6, 100-7, Are shown. Typically, a crosswalk can have two signal lights and two acoustic signals on either side of the road. Since the crossroad is all four crosswalks, eight traffic lights and eight acoustic signals can be installed. The signal light can be installed together with the sound signal. The signal lamp and the sound signal can be supplied with power from the signal lamp controller. That is, each of the plurality of sound signals 100-1, 100-2, 100-3, 100-4, 100-5, 100-6, 100-7, and 100-8 receives power from an adjacent signal lamp controller, Receiving a transverse input signal from a user, outputting a message with a sound, and communicating with an external remote controller and an acoustic signal transmitter located on the other side facing the road.

As described above, the acoustic signaler is a walking aid for the visually impaired. Thus, if the acoustic signal fails, it is dangerous and inconvenient for the visually impaired to cross the road. Therefore, it is necessary to confirm the failure of the acoustic signal device and quickly repair the failure.

In the conventional case, the manager checked the acoustic signalers one by one to check whether there is a failure and to repair the failure. Alternatively, the pedestrian can not confirm the failure of the acoustic signaling device by notifying the management center of the failure of the acoustic signaling device. When the manager checked the acoustic signalers one by one, it took a long time to check and repair the acoustic signalers. Also, since most people do not feel uncomfortable with the acoustic signal breakdown, there is a problem that the failure report is not made on time.

Accordingly, a technique has been developed in which a main diagnostic apparatus is provided to receive a failure signal from eight acoustic signals located at a short distance, and the main diagnostic apparatus again transmits a signal to the server as to whether or not the failure has occurred. However, if the main diagnosing device fails, there is a problem that a failure signal is not transmitted to the server and an additional device must be installed.

In the present disclosure, each of the eight acoustic signals 100-1, 100-2, 100-3, 100-4, 100-5, 100-6, 100-7, and 100-8 located at a range is an abnormality And a communication unit for transmitting the sensed abnormality signal to the server 200. Therefore, each of the eight sound signals 100-1, 100-2, 100-3, 100-4, 100-5, 100-6, 100-7, and 100-8 specifically determines the detected abnormal state , An abnormal signal corresponding to the determined abnormal state, and a unique identification number can be transmitted to the server 200.

That is, each of the plurality of sound signals 100-1, 100-2, 100-3, 100-4, 100-5, 100-6, 100-7, and 100-8 detects an abnormal state of the sound signal, The abnormal signal corresponding to the detected abnormal state and the unique identification number can be transmitted to the server.

The server 200 receives an abnormal signal corresponding to the abnormal state from each of the acoustic signal devices 100-1, 100-2, 100-3, 100-4, 100-5, 100-6, 100-7, By receiving the unique identification number, the manager has the advantage of being able to easily and quickly identify which part of an acoustic signal is abnormal.

Also, the server 200 can control each of the plurality of sound signals 100-1, 100-2, 100-3, 100-4, 100-5, 100-6, 100-7, and 100-8 . The server 200 may store a unique identification number for each of the sound signals. Accordingly, the server 200 can determine the specific sound signal using the unique identification number. Then, the server 200 can transmit a control signal to a specific acoustic signaler.

For example, the server 200 can control the volume or the height of the sound output from the sound signal generator 100. The sound signal generator 100 installed in a place with a high ambient noise needs to output a relatively large sound signal. Alternatively, the sound signal transmitter 100 needs to output a relatively large sound signal during the daytime when the traffic of the vehicle or the person is frequent. The server 200 may transmit a control signal for increasing the volume to the sound signaling device 100. [ The sound signal generator 100 receives the control signal for increasing the volume from the server 200, and can output a sound by increasing the volume.

Conversely, the sound signal generator 100 installed at a place where the periphery is low needs to output a relatively small sound signal. Alternatively, the sound signal generator 100 needs to output a relatively small sound signal in the night time zone. The server 20) transmits a control signal for lowering the volume to the sound signaler 100, and the sound signaler 100 can output the sound by lowering the volume according to the control signal.

In a similar manner, the server 200 can control the elevation of the sound output from the sound signal generator 100. [ For example, the server 200 may transmit a control signal for lowering the pitch to the first acoustic signaler and a control signal for increasing the pitch to the second acoustic signaler. The first sound signal generator receiving the control signal outputs a sound by lowering the pitch and the second sound signal can output sound by increasing the pitch.

Alternatively, the server 200 may control the testing of the speaker circuit of the acoustic signaling device 100. The speaker of the acoustic signaling device 100 operates when the button is pressed. That is, when the user presses the button of the sound signaling device 100, the speaker can output the corresponding voice message. However, the server 200 can test the speaker circuit by transmitting a control signal to the acoustic signaling device 100 to operate the speaker. The server 200 can control the buzzer circuit to be turned on by the sound signaler 100. [ That is, the button circuit can be switched from the off state to the on state by pushing the user or the control button control signal of the server 200. Alternatively, the button circuit may further include a separate parallel circuit operated by a control signal received from the server 200. [ Thus, the server 200 can control the operation of the speaker circuit of the acoustic signaling device 100. [

The server 200 can control the day / night reference time setting of the sound signal generator 100. That is, the server 200 can transmit the day / night time setting signal to the sound signaling device 100. [ For example, the sound signal generator 100 may be set to output sound at 50 decibels during the day and sound at 30 decibels at night. The sound signal generator 100 can determine the output decibel based on the day / night time setting signal received from the server. In other words, the server 200 can transmit a time setting signal to the sound signaling device 100 at 5 o'clock in the summer and 21 o'clock in the summer. The sound signal generator 100 receiving the control signal outputs sound at 50 decibels after 5 o'clock, and sound at 30 decibel after 21 o'clock. In addition, the server can transmit a time setting signal to the sound signaling device 100 at 7 o'clock in the winter and 19 o'clock in the winter. The sound signal generator 100 receiving the control signal outputs sound at 50 decibels after 7 o'clock, and sound at 30 decibels after 19 o'clock.

Then, the server 200 can control the nighttime volume of the sound signal generator 100. That is, the server 200 may transmit a control signal of 20 decibels at night to the audible signal 100. The sound signal generator 100 receiving the control signal can output sound at 20 decibels at night.

In addition, the server 200 can control the receiving distance of the remote control signal of the sound signal transmitter 100. [ The sound signal transmitter 100 can operate by receiving a remote control input signal from a user. When the sound signal generator 100 outputs a strong electric field sensing signal, the remote controller reception distance increases. When the sensing signal is output with a weak electric field, the remote controller reception distance decreases. The server 200 may transmit a control signal for controlling the distance of the remote control signal of the acoustic signal transmitter 100 according to circumstances. The sound signal transmitter 100 receiving the control signal can increase or decrease the remote control reception distance.

In the following, a description will be given of an object-based sound signaler according to various embodiments.

3 is a block diagram of an acoustic signaler in accordance with one embodiment of the present disclosure;

3, the sound signal generator 100 includes a power source 110, an input unit 120, a sound output unit 130, a sensing unit 140, a communication unit 150, and a processor 160.

The power supply unit 110 receives power from an adjacent traffic light controller. The traffic light controller can supply power to the acoustic signaling device 100 and the traffic light in common. The power supply unit 110 may be connected in parallel with a power supply line provided to a traffic light for lighting of a color light (e.g., red light, green light, yellow, etc.) from the traffic light controller. Therefore, when the traffic light controller supplies electric power to the traffic lights for lighting the color of the traffic lights, the sound signal transmitter 100 can receive power. In addition, the sound signal generator 100 can use the power for lighting the color of the traffic lights or the like from the traffic light controller to determine which color is illuminated.

The input unit 120 receives a cross input signal from a user. For example, the input unit 120 may include a touch key, a push key, a button, and the like. When a signal is input through the input unit 120, the sound signal generator 100 can output a message or change a turn-on color or the like after a predetermined time.

The sound output unit 130 outputs a message to the sound. The sound signal generator 100 determines the lighting state of the traffic lights. Then, the sound signal generator 100 can output a message about the currently lighted color or the like through the sound output unit 130. Alternatively, the sound output unit 130 may output a wait or a traverse message.

The sensing unit 140 senses an abnormal state of the power supply unit 110, the input unit 120, the sound output unit 130, or the communication unit 140. For example, in the sensing unit 140, the abnormal state of the power source unit 110 is 1, the abnormal state of the input unit 120 is 2, the abnormal state of the sound output unit 130 is 3, and the abnormal state of the communication unit 140 is 4, it is possible to distinguish an abnormal state detected according to each component. A specific example in which the sensing unit 140 senses an abnormal state of each component will be described later.

The communication unit 150 communicates with an external remote control, an acoustic signal unit located on the other side facing the road, and a server. The communication unit 150 can receive an input signal from an external remote controller or the like. For example, the external remote control may be a remote control carried by a blind person. The communication unit 150 receives a remote control signal input by a nearby blind person and the sound signal unit 100 can provide status information of a current traffic light to a blind person.

The communication unit 150 communicates with a sound signal unit located on the other side facing the road. When the gait signal is turned on by communicating with the acoustic signaler located on the other side facing the road, the acoustic signaler 100 alternately outputs the induction alarm signal to the acoustic signaler located on the other side . In addition, the sound signal transmitter 100 can sense an abnormal state of the communication unit 150 of the sound signaler 100 or an abnormal state of the communication unit of the sound signaler located on the other side by communicating with the sound signaler located at the other side.

In addition, the communication unit 150 performs communication with the server. The communication unit 150 may transmit the abnormal state of the sound signaling apparatus 100 to the server by communicating with the server and may transmit the statistical data of the sound signaling apparatus 100 to the server.

For example, the communication unit 150 may be a Bluetooth (R), RFID, infrared communication, UWB, ZigBee, WiFi, Wireless LAN (WLAN), Digital Living Network Alliance (DLNA), Wireless Broadband (WiBro), High Speed Downlink Packet Access , HSUPA (High Speed Uplink Packet Access), LTE (Long Term Evolution), and LTE-A (Long Term Evolution-Advanced).

The processor 160 may control the communication unit to transmit the abnormal signal corresponding to the abnormal state detected by the sensing unit 140 and the unique identification number to the server. In the following, a concrete embodiment for determining whether the sound signal transmitter 100 is abnormal will be described.

4 is a diagram for explaining a method for detecting abnormality according to an embodiment of the present disclosure.

Referring to FIG. 4, there is shown a circuit that can detect an abnormality in the sensing unit 140. In FIG. 4, only the circuit part detecting the abnormality in the sensing part 140 is shown in the entire circuit. First, an embodiment in which the sensing unit 140 detects a power source abnormality will be described. The power supply unit 130 supplies power to the sound signal generator 100. The circuit for supplying power to each component of the sound signal generator 100 in the power supply unit 130 includes a fuse 111. The fuse 111 is disconnected when it is above a predetermined voltage. The sensing unit 140 may sense a voltage at a side opposite to the one end of the fuse 111 connected to the power supply unit 130. That is, one end of the fuse 111 is connected to the power supply unit 130 and the other end is connected to the sensing unit 140.

In a normal state, the power supply unit 130 supplies power to the sound signal generator 100. [ The sensing unit 140 may sense a voltage greater than a predetermined level at the other end of the fuse 111. [ If the fuse 111 is disconnected or power is not supplied from the power supply unit 130, the voltage sensed by the sensing unit 140 becomes 0V. That is, the sensing unit 140 can sense whether the power source inputted from the power source unit 130 is turned off. The sensing unit 140 may transmit different signals to the processor according to the components. Alternatively, the sensing unit 140 may transmit a signal to the processor along with the identification information of each component. The processor can control the communication unit to forward the power failure signal to the server based on the detected power off state. When transmitting a power failure signal, the processor may transmit a unique identification number of the acoustic signaler 100 together.

On the other hand, if no power is supplied from the power supply unit 130, all components of the sound signal generator 100 can not operate. Accordingly, the acoustic signaling device 100 may include a large capacity condenser. That is, the sound signal transmitter 100 includes a large-capacity condenser and can charge the large-capacity condenser in a normal state. When the power is not supplied to the sound signal transmitter 100, the power signal abnormality signal can be transmitted to the server using the power charged in the large capacity condenser.

Next, an embodiment for detecting the abnormality of the input unit 120 will be described. As described above, the input unit 120 is a structure that receives a signal from a user through a touch or a push operation. The input unit 120 may include an anomaly detection contact 121. The abnormal detection contact 121 may be called a b contact. The abnormality detecting contact 121 is a contact which maintains an on state in a normal state and switches to an off state when an abnormality occurs. That is, in a normal state, the sensing unit 140 can sense the ON state of the anomaly detection contact 121. [ Alternatively, in a normal operating state, the sensing unit 140 may sense an off state of the instantaneous abnormality detecting contact 121. [ However, in an abnormal state, the abnormality detecting contact 121 can maintain the off state for a long time. Accordingly, the sensing unit 140 may detect an abnormality of the input unit 120 when the abnormality detection contact 121 is maintained in the off state for a predetermined time or more. The sensing unit 140 may transmit a signal indicating an abnormal state of the input unit 120 to the processor. The processor can control the communication unit to transmit an input abnormality signal to the server based on the off state of the abnormality detecting contact 121 at the sensing unit 140 for a predetermined time or more.

Next, an embodiment for detecting the abnormality of the sound output unit 130 will be described. The sound output unit 130 may include an amplifier 131 and a speaker 132. Whether the amplifier 131 and the speaker 132 are defective can be detected in the same way. When both of the amplifier 131 and the speaker 132 are in a normal state and a sound is output, a predetermined voltage may be outputted to the output terminal of the amplifier 131. [ The sensing unit 140 may sense an abnormality of the amplifier 131 and the speaker 132 by using the voltage sensed at the output terminal of the amplifier 131. [ That is, when the amplifier 131 or the speaker 132 is defective, the voltage sensed by the sensing unit 140 is 0V to several mV. In a normal state, the voltage sensed by the sensing unit 140 is several hundreds of mV . Accordingly, the sensing unit 140 can sense the voltage value of the output terminal of the amplifier 131 included in the sound output unit 130 and sense whether the sound output unit 130 is abnormal. The sensing unit 140 may transmit a signal indicating an abnormal state of the sound output unit 130 to the processor. The processor may control the communication unit to transmit an abnormal signal of the sound output unit 130 to the server when the voltage value sensed by the sensing unit 140 is less than a preset value.

On the other hand, the communication unit can be divided into detailed modules according to which of the objects to which signals are transmitted and received.

5 is a detailed block diagram of a communication unit according to an embodiment of the present disclosure;

5, the communication unit 150 may include a remote control reception module 151, a sound signal communication module 152, and a wireless communication module 153. [ The remote control receiving module 151 can receive an input signal from an external remote controller. The remote control receiving module 151 is a module capable of receiving input when a blind person uses the remote control. Since the remote control receiving module 151 can only receive signals, it can be operated only when receiving a remote control signal. Therefore, the sound signal generator 100 can calculate the number of times of daily use and judge whether there is an abnormality based on periodic usage statistics.

That is, the sound signal generator 100 can calculate the input frequency by sensing the number of external remote control input signals input through the remote control receiving module 151. Then, the sound signal generator 100 can determine the abnormal state of the remote control receiving module 151 when the calculated input frequency is equal to or less than a predetermined frequency. The sound signal transmitter 100 can transmit a remote controller receiving module error signal to the server.

The sound signal transmitter communication module 152 can communicate with the sound signal receiver located on the other side facing the road. The sound signal transmitter communication module 152 is a module for performing mutual communication by setting the same ID as the sound signal transmitter communication module of the opposite sound signal receiver. The acoustic signal transmitter communication module 152 periodically transmits a signal to the acoustic signal transversely opposite to the acoustic signal transmitter 152 and receives a response to sense abnormality.

That is, the sound signal transmitter communication module 152 is set to the same ID as the sound transmitter module of the sound signal transmitter located on the other side facing the road, and can communicate with the sound signal transmitter located at the other side at a predetermined cycle . The acoustic signal transmitter 100 can determine an abnormal state of the acoustic signal transmitter communication module of the acoustic signal transmitter 100 or the acoustic signal transmitter communication module of the other acoustic signal transmitter when the response signal is not received from the acoustic signal transmitter located at the other side. Then, the sound signal transmitter 100 can transmit a sound signal transmitter communication module error signal to the server.

The wireless communication module 153 can communicate with the server. That is, the wireless communication module 153 can transmit an anomaly signal and an acoustic signal identifier corresponding to each component to the server.

Various embodiments of a sound internet based sound signaler have been described so far.

A flow chart of the sound signal control method will be described below.
