Description

Floor-type pedestrian signal system

[0001] The present invention relates to a floor-type pedestrian signal system, and more particularly, to a floor-type pedestrian signal system buried underground where a crosswalk is installed for the safety of pedestrians.

[0002] In-floor pedestrian signal systems are installed underground, such as in roads, and emit signal lights through the surface. They are highly regarded for their utility, as they serve as stop lines or guide lines for pedestrians and can be positioned in the line of sight. In particular, with the recent increase in pedestrians looking at their smartphones as they walk, they offer the advantage of easily providing pedestrians with signal information content.

[0003] However, unlike traffic lights installed on stilts, floor-mounted pedestrian signal systems are buried underground, typically in concrete or asphalt. Their upper surfaces must constantly withstand loads and impacts from pedestrians, motorcycles, and, in some cases, vehicles. They can also be submerged in snow or rainwater during heavy rainfall. Despite the harsh installation environments, floor-mounted pedestrian signal systems must operate reliably over long periods of time.

[0004] Furthermore, ground-based pedestrian signal systems should minimize driver distraction while maximizing pedestrian visibility. Ground-based pedestrian signal systems installed at the border between the roadway (crosswalk) and the sidewalk typically display three signals: red, green, and flashing green. However, these signals can be distracting or confusing to drivers, so minimizing them is desirable.

[0005] Additionally, it is desirable for the floor-type pedestrian signal system to provide signals that enable pedestrians to safely use crosswalks while minimizing signals that may interfere with driving.

[0006] 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.

[0007] The purpose of the present invention is to provide a floor-type pedestrian signal system that outputs text and / or sound when a pedestrian leaves a safety zone of a crosswalk when a traffic light turns red in order to guide pedestrians to use the crosswalk safely.

[0008] In order to achieve the above-described purpose, a floor-type pedestrian signal system according to an embodiment of the present invention is embedded in the ground between a roadway and a sidewalk of a crosswalk, and includes a plurality of floor-type pedestrian signal devices configured to display a signal status of the crosswalk and an information display device configured to display information content, and the plurality of floor-type pedestrian signal devices and the information display devices are arranged in a row.

[0009] A plurality of floor-type pedestrian signal devices may include a plurality of LED elements arranged in a matrix, and the plurality of LED elements may be configured to light a first color when a first control signal corresponding to a red light on the crosswalk is input, light a second color when a second control signal corresponding to a green light on the crosswalk is input, and blink the second color when a third control signal corresponding to a green light on the crosswalk is input.

[0010] The information display device can be placed at the end of a line formed by arranging a plurality of floor-type pedestrian signal devices and information display devices in a row.

[0011] An information display device may be configured to include a communication module that receives information content, a control module that generates and outputs an information content output request message including information content in response to information content transmission of the communication module, and a display module that outputs information content from the information content output request message in response to the information content output request message of the control module and outputs the information content.

[0012] An information display device may be configured to output information content when a first control signal corresponding to a red light of a crosswalk is input. The information display device may be configured to output the information content so as to overlap with a first color lighting image, and the first color lighting image may be an image in which a plurality of LED elements arranged in a matrix output the first color. The information display device may be configured to output a background of the first color and output the information content so as to overlap with the background of the first color. The information display device may be configured to output a frame image of the first color having a display area and output the information content so as to overlap with the display area.

[0013] The information display device may be configured to output a first color lighting image in which a plurality of LED elements arranged in a matrix output a first color when a first control signal is input in a state in which no information content is input.

[0014] The information display device may be configured to output a signal status of a crosswalk to which one of the second control signal and the third control signal corresponding to the green light and the orange light of the crosswalk is input.

[0015] The information display device is configured to output a second color lighting image when a second control signal corresponding to the green lighting of a crosswalk is input, and the second color lighting image may be an image in which a plurality of LED elements arranged in a matrix output a second color.

[0016] The information display device is configured to output a second color flashing image when a third control signal corresponding to the orange lighting of the crosswalk is input, and the second color flashing image may be an image in which a plurality of LED elements arranged in a matrix flash the second color.

[0017] The information display device is configured to output a second color lighting image at a set cycle interval when a third control signal corresponding to the orange lighting of the crosswalk is input, and the second color lighting image may be an image in which a plurality of LED elements arranged in a matrix output the second color.

[0018] An information display device may be configured to include a communication module for receiving information content, an input module for receiving a control signal corresponding to a signal state of a crosswalk, a control module for generating and outputting one of an information content output request message and a signal state output request message in response to the information content transmission of the communication module and the control signal transmission of the input module, and a display module for outputting information content detected from the information content output request message in response to the information content output request message of the control module and outputting the signal state of the crosswalk in response to the signal state output request message of the control module.

[0019] According to the present invention, a floor-type pedestrian signal system includes a plurality of floor-type pedestrian signal devices that display the signal status of a crosswalk and a display device that outputs information content, thereby having the effect of providing various information to pedestrians along with the signal status of the crosswalk.

[0020] In addition, the floor-type pedestrian signal system has the effect of allowing pedestrians to check various information while checking the signal status of the crosswalk by placing an information display device at the end of a line formed by arranging a plurality of floor-type pedestrian signal devices and information display devices in a row.

[0021] In addition, the floor-type pedestrian signal system can minimize the sense of incongruity felt by pedestrians between the floor-type pedestrian signal device and the information display device by configuring the information display device to display information content while indicating the signal status of the same crosswalk as the floor-type pedestrian signal device.

[0031] Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the attached drawings.

[0032] These examples are provided to more fully illustrate the present invention to those skilled in the art. The following examples may be modified in various ways, and the scope of the present invention is not limited to the examples described below. Rather, these examples are provided to further faithfully and completely convey the spirit of the present invention.

[0033] The terms used herein are used to describe specific embodiments and are not intended to limit the present invention. Furthermore, the singular forms used herein may include the plural forms, unless the context clearly dictates otherwise.

[0034] The drawings are intended solely to facilitate understanding of the invention and should not be construed as limiting the scope of the invention. Furthermore, relative thicknesses, lengths, and sizes in the drawings may be exaggerated for convenience and clarity of explanation.

[0035] Referring to Fig. 1, a floor-type pedestrian signal device (11) can generally be installed embedded in the ground on one side of a curb (40) of a crosswalk (20) installed between a road and a sidewalk. At this time, the floor-type pedestrian signal device (11) is connected to another adjacent floor-type pedestrian signal device (11) via a cable.

[0036] A plurality of floor-type pedestrian signal devices (11) can be electrically connected to a signal controller (12) located outside the road or the like and linked to a crosswalk signal light (not shown).

[0037] For example, when the red lamp of the crosswalk signal light is turned on by the control of the signal controller (12), the red LED element in the floor-type pedestrian signal device (11) may also be turned on to emit red light. In addition, when the switching module of the crosswalk signal light is turned on by the control of the signal controller (12), the green LED element in the floor-type pedestrian signal device (11) may also be turned on to emit green light. At this time, when the switching module of the crosswalk signal light blinks by the control of the signal controller (12), the green LED element in the floor-type pedestrian signal device (11) may also blink. In this way, the floor-type pedestrian signal device (11) installed buried in the ground is displayed in red, green, and green blinking by the signal controller (12), allowing a pedestrian walking with his or her head down and looking at a mobile phone to recognize the surrounding situation.

[0038] Referring to Fig. 2, a plurality of floor-type pedestrian signal devices (11) are installed on a crosswalk and are connected to each other in the left and right directions using cables.

[0039] The first floor-type walking signal device (11a) is connected to the controller (13), the second floor-type walking signal device (11b) is connected to the first floor-type walking signal device (11a), and the third floor-type walking signal device is connected to the second floor-type walking signal device (11b). Although not shown in Fig. 2, the nth floor-type walking signal device (11n) is connected to the n-1th floor-type walking signal device (11).

[0040] In a conventional floor-type pedestrian signal device control system, a signal controller (12) transmits a control signal (ON, OFF, Blink) to a controller (13), and the controller (13) applies a constant current power supply to the floor-type pedestrian signal device (11) according to the control signal.

[0041] A plurality of floor-type pedestrian signal devices (11) can be electrically connected to a signal controller (12) located outside the road or the like and linked to a crosswalk signal light (not shown).

[0042] For example, when the red lamp of the crosswalk signal light is turned on under the control of the signal controller (12), the red LED element in the floor-type pedestrian signal device (11) may also be turned on to emit red light.

[0043] In addition, when the switching module of the crosswalk signal light is turned on under the control of the signal controller (12), the green LED element within the floor-type pedestrian signal device (11) may also be turned on to emit green light. At this time, when the switching module of the crosswalk signal light is blinked under the control of the signal controller (12), the green LED element within the floor-type pedestrian signal device (11) may also blink.

[0044] In this way, the floor-type pedestrian signal device (11) installed buried in the ground is displayed as a red light, a green light, and a green flash by a signal controller (12), so that a pedestrian walking while looking at a cell phone with his head down can be aware of the surrounding situation.

[0045] Referring to FIG. 3, a floor-mounted pedestrian signal system (100) according to an embodiment of the present invention displays the signal status of a crosswalk (20) through red lighting, green lighting, and green flashing, while simultaneously displaying information content. Here, the information content is content comprised of at least one of text, video, and image, and is, for example, promotional content corresponding to corporate advertising content, public institution policies, and lifestyle guides.

[0046] Referring to FIG. 4, a floor-type pedestrian signal system (100) according to an embodiment of the present invention is configured to include a plurality of floor-type pedestrian signal devices (120) and an information display device (140).

[0047] A plurality of floor-type pedestrian signal devices (120) are arranged in parallel along the curb (40) of the crosswalk (20). The plurality of floor-type pedestrian signal devices (120) are arranged along a first line parallel to the curb (40) so as to be parallel to the curb (40).

[0048] A plurality of floor-type pedestrian signal devices (120) indicate the signal status of the crosswalk (20). The plurality of floor-type pedestrian signal devices (120) indicate the signal status of the crosswalk (20) by turning red, turning green, and blinking green based on a control signal from a signal controller (12, or controller (13)).

[0049] Referring to FIG. 5, the floor-type pedestrian signal device (120) includes a plurality of LED elements (122) arranged in a matrix.

[0050] When a first control signal corresponding to a red light of a traffic light is input, the floor-type pedestrian signal device (120) lights up a plurality of LED elements (122) in red. When a second control signal corresponding to a green light of a traffic light is input, the floor-type pedestrian signal device (120) lights up a plurality of LED elements (122) in green. When a third control signal corresponding to an orange light of a traffic light is input, the floor-type pedestrian signal device (120) blinks a plurality of LED elements (122) in green. Through this, the plurality of floor-type pedestrian signal devices (120) indicate the signal status of the crosswalk (20).

[0051] The information display device (140) is placed at the end (right end in the drawing) of a line formed by arranging a plurality of floor-type pedestrian signal devices (120) side by side.

[0052] Since the information display device (140) displays information content, when placed between a plurality of floor-type pedestrian signal devices (120), it may actually hinder pedestrians from checking the signal status of the crosswalk (20). That is, pedestrians may not be able to check the signal status of the crosswalk (20) displayed on the floor-type pedestrian signal devices (120) because they focus on the information content displayed on the information display device (140).

[0053] Accordingly, a plurality of floor-type pedestrian signal devices (120) are arranged in parallel along the curb (40) of the crosswalk (20) so as to be parallel to the curb (40), and the information display device (140) is arranged at the end (right end in the drawing) of the line formed by the plurality of floor-type pedestrian signal devices (120) arranged in parallel.

[0054] For example, it is assumed that the floor-type walk signal system (100) includes a first floor-type walk signal device (120a), a second floor-type walk signal device (120b), a third floor-type walk signal device (120c), a fourth floor-type walk signal device (120d), and a display device. The first floor-type walk signal devices (120a) to the fourth floor-type walk signal devices (120d) are arranged side by side, and the display device is arranged on the right side of the fourth floor-type walk signal device (120d) in the drawing. Here, in FIG. 3, the display device is illustrated and described as being arranged on the right side of the fourth floor-type walk signal device (120d), but the present invention is not limited thereto and may be arranged on the left side of the first floor-type walk signal device (120a).

[0055] The information display device (140) is configured to include a display such as an LCD or OLED. The information display device (140) receives information content from an external terminal (hereinafter, “external terminal”) via wired or wireless communication. The information display device (140) displays the information content provided from the external terminal. At this time, the information display device (140) outputs the information content regardless of the signal status of the crosswalk (20). In other words, the information display device (140) outputs the information content when the information content is input from an external device, regardless of the signal status of the crosswalk (20).

[0056] Referring to FIG. 6, the information display device (140) is configured to include a communication module (142), a control module (144), and a display module (146).

[0057] The communication module (142) is connected to an external device via wired or wireless communication and receives information content from the external device. Here, the communication module (142) receives information content composed of at least one of text, video, and image, such as promotional content corresponding to corporate advertising content, public institution policies, and lifestyle guides, from the external device, as an example. The communication module (142) transmits the information content received from the external device to the control module (144).

[0058] The control module (144) generates an information content output request message in response to the information content transmission of the communication module (142). The control module (144) generates an information content output request message including the information content transmitted from the communication module (142). The control module (144) transmits the information content output request message to the display module (146).

[0059] The display module (146) outputs information content in response to an information content output request message from the control module (144). The display module (146) detects text, video, images, etc. from the information content output request message. The display module (146) outputs text, video, and images. To this end, the display module (146) is configured to include a display such as an LCD or OLED to output text, video, and images. In addition, the display module (146) may be configured to include another display capable of outputting text, video, and images.

[0060] Referring to FIG. 7, the floor-type pedestrian signal system (100) may be configured to output information content only when the crosswalk (20) is in a red light state. That is, the floor-type pedestrian signal system (100) is configured so that the information display device (140) outputs information content in a red light state when the pedestrian remains stationary, in order to increase the efficiency of the information provision service. At this time, the floor-type pedestrian signal system (100) is configured so that the information display device (140) outputs the signal status of the crosswalk (20) in a green light and green blinking state when the pedestrian is in a moving state.

[0061] To this end, referring to FIG. 8, the floor-type pedestrian signal system (100) may further include an input module (148) that receives a control signal corresponding to the lighting status of a traffic light installed on a crosswalk (20).

[0062] The input module (148) receives one of a first control signal corresponding to red lighting, a second control signal corresponding to green lighting, and a third control signal corresponding to orange lighting from a signal controller or a controller. The input module (148) transmits the control signal received from the signal controller to the control module (144).

[0063] The control module (144) generates one of an information content output request message and a signal status output request message as an output request message in response to a control signal transmission from the input module (148). The control module (144) transmits the output request message to the display module (146).

[0064] For example, when a first control signal corresponding to a red light state of a crosswalk (20) is received from the input module (148), the control module (144) generates an information content output request message including information content and transmits the message to the display module (146). At this time, the control module (144) may also generate an information content output request message including the first control signal and information content and transmit the message to the display module (146). At this time, when the control module (144) does not receive information content from the communication module (142), the control module (144) transmits a red light output request message to the display module (146).

[0065] When a second control signal corresponding to the green lighting state of the crosswalk (20) is received from the input module (148), the control module (144) generates a green lighting output request message and transmits it to the display module (146).

[0066] When a third control signal corresponding to the orange lighting state of the crosswalk (20) is received from the input module (148), the control module (144) generates a green flashing output request message and transmits it to the display module (146).

[0067] The display module (146) outputs information content in response to an output request message from the control module (144). That is, if the output request message from the control module (144) is an information content output request message, the display module (146) outputs information content in response to the information content output request message. The display module (146) detects and outputs information content from the information content output request message.

[0068] At this time, if the output request message of the control module (144) is a red light output request message, the display module (146) outputs a red light image (A).

[0069] For example, referring to FIG. 9, the display module (146) outputs a red light image (A) identical to the state in which a plurality of LED elements (122) arranged in a matrix output red light in response to a red light output request message of the control module (144).

[0070] If the output request message of the control module (144) is an information content output request message including the first control signal and information content, the display module (146) outputs a red light state and information content.

[0071] At this time, the display module (146) can output the red lighting status and information content in various formats.

[0072] For example, referring to FIG. 10, the display module (146) outputs a red background and overlaps and outputs information content on the red background. In the case of information content composed of text, the display module (146) may output text in a complementary color of white or red.

[0073] As another example, referring to FIG. 11, the display module (146) can output a red frame image (C) having a display area (B), and output information content by overlapping it on the display area (B) of the red frame image (C).

[0074] Meanwhile, when information content is output on a red background or red frame, pedestrians may feel a sense of incongruity between the red light displayed on the floor-type pedestrian signal device (120) and the red background displayed on the information display device (140).

[0075] Accordingly, the display module (146) outputs information content while outputting a signal status in the same manner as the floor-type walking signal device (120).

[0076] For example, referring to FIG. 12, the display module (146) outputs a red light-up image (A) identical to the state in which a plurality of LED elements (122) arranged in a matrix output red as a background, and outputs information content so as to overlap with the red light-up image (A). In the case of information content composed of text, the display module (146) can output text in the complementary color of white or red.

[0077] Through this, the display module (146) can output a background identical to the red lighting state of the floor-type walk signal device (120), thereby minimizing the sense of incongruity between the floor-type walk signal device (120) and the information display device (140).

[0078] If the output request message of the control module (144) is a green light output request message, the display module (146) outputs a green light image (D) in response to the green light output request message. The display module (146) can output a green light image (D) configured in the same manner as a floor-type pedestrian signal device (120) when outputting the signal status of a crosswalk (20).

[0079] For example, referring to FIG. 13, the display module (146) responds to a green lighting output request message from the control module (144) by outputting a green lighting image (D) identical to the state in which a plurality of LED elements (122) arranged in a matrix output green.

[0080] If the output request message of the control module (144) is a green flashing output request message, the display module (146) outputs a green flashing image in response to the green flashing output request message. At this time, the display module (146) can output a green flashing image configured in the same manner as the floor-type pedestrian signal device (120) when outputting the signal status of the crosswalk (20).

[0081] For example, referring to FIG. 14, the display module (146) outputs a green blinking image (E) identical to the state in which a plurality of LED elements (122) arranged in a matrix output a green blinking color in response to a green blinking output request message of the control module (144).

[0082] The display module (146) may output a green flashing state by outputting a green flashing image (D) at a set cycle in response to a green flashing output request message.
