Description
Acoustic and floor pedestrian signal control devices and control systems
[0001] The present invention relates to an acoustic and floor walking signal control device that integrates and controls an acoustic signal device and a floor walking signal device for the visually impaired, and more particularly, to an acoustic and floor walking signal control device and system that enhances safety and efficiency by integrating and controlling an acoustic signal device and a floor walking signal device used for crosswalk signal guidance purposes.
[0002] Conventional pedestrian signal poles are equipped with an audible signal device for the visually impaired and a ground-level pedestrian signal control device. Each device's housing is a steel structure, and its size and weight detract from the aesthetic appeal of the crosswalk signal pole and pose a risk of falling due to its weight.
[0003] Additionally, the audible signal device for the visually impaired was directly connected to the green and red power lines of the crosswalk signal, and the signal was determined by the presence or absence of power in each power line. Since the green and red power lines of the traffic light are directly connected to the audible signal device for the visually impaired, a malfunction in the audible signal device for the visually impaired could cause a short circuit in the connected power lines, potentially leading to a malfunction of the crosswalk signal.
[0004] Additionally, since the audio signal device for the visually impaired communicates wirelessly with other audio signal devices for the visually impaired, there are cases where the communication quality deteriorates due to the influence of surrounding radio waves, resulting in signal errors.
[0005] The matters described in the background art above are intended to help understand the background of the invention and may include matters that are not publicly disclosed prior art.
[0006] The present invention has been proposed to solve the above-mentioned problems, and can improve both appearance and safety by integrating the structures of an acoustic signal device for the visually impaired and an on-floor pedestrian signal control device. In addition, since it is configured as an integrated control device and determines a traffic light signal by receiving a traffic signal control signal of a traffic signal control device rather than using the power of a traffic light to determine a traffic light signal, it can fundamentally prevent a failure of an acoustic signal device for the visually impaired from inducing a failure of a crosswalk signal light, while enabling efficient control. In addition, the purpose of the present invention is to provide a system that connects wired communication between the acoustic and on-floor pedestrian signal control devices installed at a crosswalk, thereby eliminating factors of communication errors (wireless communication failure) that may occur between devices due to conventional wireless communication.
[0007] In order to achieve the above object, an acoustic and floor walk signal control device according to an embodiment of the present invention is an acoustic and floor walk signal control device that integrates and controls an acoustic signal device for the visually impaired used for the purpose of providing crosswalk signal guidance and an on-floor walk signal device, the acoustic and floor walk signal control device including a system control unit that receives a traffic signal control signal from a traffic signal control device and transmits an acoustic signal device control signal to the acoustic signal device and transmits an on-floor walk signal light control signal to the on-floor walk signal light device, a power supply unit that supplies electric energy to the system control unit, and an acoustic signal device that receives an acoustic signal device control signal from the system control unit and outputs an acoustic signal in accordance with the walk signal of the crosswalk signal light, an acoustic signal communication module unit that receives a traffic signal control signal from the traffic signal control device, an acoustic signal microcontroller that receives a traffic signal control signal from the acoustic signal communication module unit and transmits an acoustic signal device control signal to the acoustic signal device, and an on-floor walk signal communication microcontroller that receives a traffic signal control signal from the traffic signal control device and transmits an on-floor walk signal control signal to the on-floor walk signal light device.

[0033] FIG. 1 is a drawing showing an acoustic and floor walking signal control system (1) according to an embodiment of the present invention.
[0034] As illustrated in Fig. 1, a traffic signal control device (10) applied to an acoustic and floor pedestrian signal control system (1) is a device that receives a crosswalk signal light traffic system signal (A) and controls a signal of a crosswalk (80) signal light (90). The traffic signal control device (10) includes a traffic signal control unit (11) and an option board (12). The option board (12) is attached to the traffic signal control unit (11). The option board (12) receives a traffic signal control unit signal (B) from the traffic signal control unit (11) and transmits a traffic signal control signal (C) to the acoustic and floor pedestrian signal control device (20).
[0035] The sound and floor pedestrian signal control device (20) is installed on the light pole (the pillar on which the signal light is installed) of the crosswalk (80) signal light (90). The sound and floor pedestrian signal control device (20) receives power other than the power of the crosswalk (80) signal light (90) and supplies the power back to the floor pedestrian signal light device (900).
[0036] The sound and floor walking signal control device (20) receives power and transmits it to the floor walking signal light device (900). The power transmission method may use a method in which the sound and floor walking signal control device (20) is directly received by different floor walking signal light devices (900), or a method in which the power is received by one floor walking signal light device (900) and the received power is transmitted and received between adjacent floor walking signal light devices (900).
[0037] The sound and floor walking signal control device (20) receives a traffic signal control signal (C) from the option board (12) and transmits the traffic signal control signal (C) to another sound and floor walking signal control device (20-1).
[0038] In addition, the sound and floor pedestrian signal control device (20) receives a traffic signal control signal (C) from the option board (12) and transmits a floor pedestrian signal control signal (E) to the floor pedestrian signal light device (900). The signal transmission method may include a method in which the floor pedestrian signal control signal (E) is transmitted from the sound and floor pedestrian signal control device (20) and directly received by each different floor pedestrian signal light device (900), and a method in which the floor pedestrian signal control signal (E) is received by one floor pedestrian signal light device (900) and the received floor pedestrian signal control signal (E) is transmitted and received between adjacent floor pedestrian signal light devices (900).
[0039] The floor pedestrian signal light device (900) can be installed embedded in the ground on one side of a crosswalk (80). At this time, the floor pedestrian signal light device (900) is connected to each adjacent different floor pedestrian signal light device (900) via a cable. In addition, as described above, the floor pedestrian signal light device (900) receives and determines the floor pedestrian signal light device control signal (E) and transmits green, green flashing, and red LEDs.
[0040] The pedestrian signal information confirmation remote control (50) is a device that transmits a pedestrian signal information confirmation remote control signal (G) to a remote control receiving antenna (200) to request that the pedestrian signal and the location guidance information of the traffic light (90) of a crosswalk (80) be transmitted as sound.
[0041] The audio signal confirmation button (800) is a device that transmits an audio signal confirmation button signal (H) to the system control unit (100).
[0042] The sound signal confirmation button (800) is a device that is installed on a light pole (a pillar on which a traffic light is installed) of a crosswalk (80) traffic light (90) and transmits an sound signal confirmation button signal (H) to the system control unit (100) to request that sound be transmitted in accordance with the pedestrian signal of the crosswalk (80) traffic light (90).
[0043] The floor pedestrian signal light device (900) receives a signal from the sound and floor pedestrian signal control device (20) and outputs green, green flashing, and red LEDs in accordance with the green, green flashing, and red signal lighting of the crosswalk (80) signal light (90).
[0044] For example, when the red lamp of the crosswalk signal light (90) is turned on by the control of the acoustic and floor walking signal control device (20), the speaker output unit (630) of the acoustic signal device (600) outputs the red signal of the signal light acoustically, and the red LED element of the LED of the floor walking signal light device (900) lights up together to emit red light. In addition, when the green lamp of the crosswalk signal light (90) is turned on by the control of the acoustic and floor walking signal control device (20), the speaker output unit (630) of the acoustic signal device (600) outputs the green signal of the signal light acoustically, and the green LED element of the LED of the floor walking signal light device (900) lights up together to emit green light. The floor walking signal light device (900) installed buried in the ground displays red, green, and green flashing by the acoustic and floor walking signal control device (20) so that a pedestrian walking with his or her head down and looking at his or her cell phone can recognize the surrounding situation. Additionally, by providing traffic light signals through sound, it is expected to have the effect of preventing accidents by increasing the convenience and concentration of all pedestrians, not just the visually impaired.
[0045] Fig. 2 is a drawing showing an acoustic and floor walking signal control device (20) according to an embodiment of the present invention.
[0046] Referring to Fig. 2, the sound and floor walking signal control device (20) is composed of a system control unit (100), a remote control receiving antenna (200), a power supply unit (300), a leakage circuit breaker (400), a surge protector (500), an sound signal device (600), and an sound signal confirmation button (800).
[0047] The sound and floor walking signal control device (20) is a device that integrates the structure and function of an sound signal device for the visually impaired and a floor walking signal control device.
[0048] The system control unit (100) serves to control the devices included in the sound and floor walking signal control device (20). The system control unit (100) receives and controls a traffic signal control signal (C) from the option board (12) and transmits an sound signal device control signal (D) to the sound signal device (600).
[0049] In addition, the system control unit (100) receives and controls a traffic signal control signal (C) from the option board (12) and transmits a floor pedestrian signal device control signal (E) to the floor pedestrian signal device (900).
[0050] Additionally, the system control unit (100) receives and controls a traffic signal control signal (C) from the option board (12) and transmits the traffic signal control signal (C) to another sound and floor pedestrian signal control device (20-1).
[0051] The remote control receiving antenna (200) is an antenna device that receives a pedestrian signal information confirmation remote control signal (G) from a pedestrian signal information confirmation remote control (50) and transmits it to the system control unit (100), and is a device that requests the system control unit (100) to transmit information on the pedestrian signal and the location of the current crosswalk (80) signal light (90) as sound.
[0052] The power supply unit (300) is composed of an AC / DC converter (310) and a DC / DC converter (320), and serves to receive power, convert it to suit the device, and output it.
[0053] A leakage circuit breaker (400) is used to prevent electric shock and fire by cutting off electricity when a leakage occurs in the system.
[0054] A surge protector (500) is used to prevent damage to power equipment from lightning strike voltage within the system.
[0055] The sound signal device (600) is used to output sound in accordance with the pedestrian signal of the crosswalk (80) traffic light (90), and receives a signal from the system control unit (100) and outputs sound in accordance with the pedestrian signal of the crosswalk (80) traffic light (90).
[0056] The audio signal confirmation button (800) is a button that requests audio output in accordance with the pedestrian signal of a traffic light at a crosswalk. When the button is pressed, a signal is transmitted to the system control unit (100), and the system control unit (100) determines and outputs audio in accordance with the pedestrian signal of the traffic light.
[0057] Conventional audio signal devices for the visually impaired were directly connected to the green and red power lines of the crosswalk (80) signal light (90) and determined the traffic light signal based on whether or not power was supplied to each power line. In addition, since the green and red power lines of the crosswalk (80) signal light (90) were directly connected to the audio signal device for the visually impaired, if a malfunction occurred in the audio signal device for the visually impaired, a current leakage occurred in the connected power line, which could lead to a malfunction of the crosswalk (80) signal light (90).
[0058] The acoustic and floor walking signal control device (20) of the present invention is a device that integrates the structure and function of an acoustic signal device for the visually impaired and an on-floor walking signal control device. The acoustic and floor walking signal control device (20) does not use the power of the traffic light (90) to determine the signal of the traffic light (90), but receives the traffic signal control signal of the traffic signal control device to determine the signal of the traffic light. Since the power of the acoustic and floor walking signal control device (20) is not connected to the traffic light (90), unlike the conventional invention that induces a malfunction of the crosswalk (80) signal light (90) due to a malfunction of the acoustic signal device for the visually impaired, it can fundamentally prevent the induction of a malfunction. In addition, it is efficient because the acoustic signal device for the visually impaired and the on-floor walking signal control device can be controlled as a single integrated device and system.
[0059] Additionally, the system eliminates communication errors (wireless communication failures) that can occur between devices due to conventional wireless communication by connecting wired communication between acoustic and floor pedestrian signal control devices installed at crosswalks. This improves pedestrian safety.

[0061] Referring to Fig. 3, the acoustic and floor pedestrian signal control system (1) is composed of a traffic signal control device (10), an acoustic and floor pedestrian signal control device (20), and a floor pedestrian signal light device (900). The traffic signal control device (10), the acoustic and floor pedestrian signal control device (20), and the floor pedestrian signal light device (900) are signal-connected.
[0062] The traffic signal control device (10) is a device that transmits a traffic signal control signal (C) to the acoustic and floor pedestrian signal control device (20). The acoustic and floor pedestrian signal control device (20) controls the received traffic signal control signal (C) and transmits it to the system within the device, and generates an acoustic and floor pedestrian signal light control signal (E) and transmits it to the acoustic and floor pedestrian signal light device (900). The systems of each device that receives the signal output according to each signal. For example, the acoustic and floor pedestrian signal control device (20) outputs sound according to the pedestrian signal of the crosswalk (80) signal light (90) from the speaker output unit (630) of the acoustic signal device (600), and the acoustic and floor pedestrian signal light device (900) may also emit light by lighting up green, green blinking, and red LED elements together in the acoustic and floor pedestrian signal light device (900) according to the pedestrian signal of the crosswalk (80) signal light (90).

[0093] Referring to FIG. 9, the audio signal device (600) is composed of a speaker communication unit (610), a speaker control unit (620), and a speaker output unit (630).
[0094] The speaker communication unit (610) receives an audio signal device control signal (D) from the system control unit (100) and transmits the audio signal device control signal (D) to the speaker control unit (620). The speaker control unit (620) receives and controls the audio signal device control signal (D) from the speaker communication unit (610) to transmit a speaker control signal (D1). The speaker output unit (630) receives the speaker control signal (D1) from the speaker control unit (620) and outputs sound in accordance with the pedestrian signal of the crosswalk (80) traffic light (90).
[0095] For example, the sound signal device (600) outputs a sound such as "The crosswalk has a green light. You may cross" from the speaker output unit (630) when the green light of the crosswalk (80) signal light (90) is on. When the green light flashes, the speaker output unit (630) outputs a sound such as "The signal has changed to a flashing signal. Please cross quickly." When the red light flashes, the speaker output unit (630) outputs a sound such as "It is dangerous. Please wait for the next signal."
[0096] In addition, when the pedestrian signal information confirmation remote control (50) and the audio signal confirmation button (800) are operated, sound is output according to the green lighting, green flashing, and red lighting status of the crosswalk (80) signal light (90). When the green signal is on, the speaker output unit (630) outputs a sound such as "The crosswalk light is on green. You may cross." When the green signal is on, the speaker output unit (630) outputs a sound such as "The signal has changed to flashing. Please cross quickly." When the red signal is on, the speaker output unit (630) outputs a sound such as "It is dangerous, so please wait for the next signal."
[0097] By providing such sounds, we can expect to prevent accidents by increasing the convenience and concentration of all pedestrians, not just those with visual impairments.
[0098] Figure 10 is a block diagram of a communication module (700) between system control units according to an embodiment of the present invention.
[0099] Referring to Fig. 10, the inter-system control unit communication module (700) receives a traffic signal control signal (C) from the option board (12) and transmits it to another sound and floor pedestrian signal control device (20-1). More precisely, it transmits it to another inter-system control unit communication module (700-1) of another sound and floor pedestrian signal control device (20-1). The other sound and floor pedestrian signal control device (20-1) controls the received traffic signal control signal (C) to output sound and light emission in accordance with the pedestrian signal of the crosswalk (80) signal light (90).
[0100] By using wired communication between the acoustic and floor pedestrian signal control device (20) and another acoustic and floor pedestrian signal control device (20-1), the occurrence of signal errors due to deterioration of communication quality caused by the influence of surrounding radio waves, which is a problem with acoustic devices for the visually impaired that use only conventional wireless communication, can be prevented. As a result, it is expected that stable crosswalk operation will be possible.
[0101] Fig. 11 is a block diagram of a floor pedestrian signal light device (900) according to an embodiment of the present invention.
[0102] Referring to FIG. 11, the floor pedestrian signal light device (900) is composed of a floor pedestrian signal light communication unit (910), a floor pedestrian signal light control unit (920), and a floor pedestrian signal light output unit (930).
[0103] The floor pedestrian signal communication unit (910) receives the floor pedestrian signal device control signal (E) from the system control unit (100) and transmits it to the floor pedestrian signal control unit (920). The floor pedestrian signal control unit (920) receives the floor pedestrian signal device control signal (E) from the floor pedestrian signal communication unit (910) and transmits the floor pedestrian signal control signal (E1) to the floor pedestrian signal output unit (930). The floor pedestrian signal output unit (930) receives the floor pedestrian signal control signal (E1) from the floor pedestrian signal control unit (920) and emits light in accordance with the pedestrian signal of the crosswalk (80) signal light (90).
[0104] For example, the floor pedestrian signal light output, when the green signal of the crosswalk (80) signal light (90) is turned on, the floor pedestrian signal light device (900) outputs a green LED. When the green blinking signal is turned on, the floor pedestrian signal light device (900) outputs a blinking green LED. When the red signal is turned on, the floor pedestrian signal light device (900) outputs a red LED.
[0105] By providing such floor pedestrian traffic lights, the visibility and concentration of the crosswalk (80) and traffic light (90) signals for pedestrians and drivers can be improved, and the convenience and concentration of all pedestrians, not just the visually impaired, can be increased, which is expected to have the effect of preventing accidents.
