Description

Technology Field

[0001] The present invention relates to a tunnel and road entry blocking device configured to prevent secondary accidents by displaying emergency situations, such as traffic accidents, fires, or flooding of the underpass that may occur inside or outside the road, to drivers of vehicles entering tunnels, highways, or underpasses, and transmitting this information in advance. Background Technology

[0003] Generally, tunnels are formed by penetrating mountains or other terrain in the region to facilitate the rapid passage of vehicles traveling on highways, and they have the advantage of minimizing driving time and fuel consumption by reducing the vehicle's driving distance to the maximum limit.

[0004] However, tunnels with the aforementioned advantages pose a relatively high risk of suffocation accidents because, in the event of a fire caused by a vehicle accident or electrical short circuit inside, it is difficult to vent and disperse flames and smoke to the outside. Furthermore, if a vehicle entering the tunnel fails to notice the fire while driving on the highway, rapid evacuation becomes extremely difficult, raising concerns about large-scale human and material damage.

[0005] Therefore, in the event that an emergency situation such as a fire occurs inside the tunnel as described above, measures must be taken to prevent entry into the tunnel by notifying subsequent vehicles traveling toward the tunnel that an emergency situation, such as a fire, has occurred inside the tunnel.

[0006] Conventionally, as a means of blocking entry to such tunnels, indicator lights prohibiting entry were installed on the tunnel entrance, or gate-shaped pillars were installed on the tunnel entrance, with banners prohibiting entry lowered from the top of the pillars toward the road surface.

[0007] However, simply installing a no-entry sign on the entrance to the tunnel is insufficient to alert drivers of subsequent vehicles that there is a fire inside the tunnel, and it is not possible to accurately inform them of the situation inside the tunnel. Furthermore, allowing the banner to descend toward the road surface has the problem that the banner obstructs the driver's view, potentially causing a secondary accident, and the banner is difficult to recognize as it is blown away by the wind and passing vehicles.

FIG. 3 is a drawing showing the water discharge configuration of a display means according to one embodiment of the present invention. FIG. 4 is a drawing showing an example of implementation of a display image of a display means that is a component of the present invention. FIG. 5 is a block diagram showing a measuring unit according to one embodiment of the present invention. Specific details for implementing the invention

[0027] In describing the present invention, terms and words used in this specification and claims must be interpreted in a meaning and concept consistent with the technical spirit of the invention, based on the principle that the inventor can appropriately define the concept of the terms to best describe his invention.

[0028] Preferred embodiments of the present invention will be described below with reference to the drawings.

[0030] Referring to FIG. 1, the device of the present invention may be configured to include an output unit (10) in which one or more guidance information is stored and guidance information selected by a situational signal input from the outside is output, a guidance unit (20) equipped with a display means, and a control unit (30) that controls the operation of the guidance unit (20).

[0031] The output unit (10) above may store one or more pre-entered guidance information.

[0032] The above guidance information is a designated phrase prepared for the purpose of maintaining controlled roads including tunnels (1), highways, underpasses, etc., and can be designated and displayed by the manager according to the situation and can be changed at any time.

[0033] Such guidance information can be input to the output unit (10) through an administrator terminal (40). For example, the administrator terminal (40) is a terminal granted access rights to the device of the present invention, and may be a fixed terminal such as a desktop or a mobile terminal such as a smartphone or tablet, and may communicate data with the output unit (10) through a selected wired or wireless network.

[0034] And the above guidance information is information for visually guiding the driver of a vehicle using a controlled road including a tunnel (1) to the internal and external conditions of the road, and may be composed of one or more combinations of selected letters, symbols, and numbers.

[0035] The above guidance unit (20) may be installed in front of the entrance to the road to be controlled, and may be equipped with a display means (200) to display guidance information selected and output from the above output unit (10).

[0036] Although the above guide (20) is shown in FIG. 1 as being installed in each of the two-way entrances to the tunnel (1), the present invention is not limited thereto, and it is obvious that the installation direction and installation location may differ slightly depending on the form and structure of the entrance and exit of the controlled road, such as a highway or an underground road.

[0037] The display means (200) according to one embodiment of the present invention may be configured to display various characters, etc. in the form of a water stream using the falling of water and the time difference of falling.

[0038] Specifically, the above-mentioned display means (20) may be configured to include a fixed frame (210), a storage tank (220), an opening / closing valve (230), a discharge nozzle (240), and a distribution pipe (221), as shown in FIGS. 2a to 3.

[0039] The above fixed frame (210) can be installed upright at the entrance of the controlled road.

[0040] The above fixed frame (210) can be installed upright by combining a transverse frame (211) and a longitudinal frame (212), and it is preferable to install it at a location sufficiently far from the entrance so that it does not obstruct traffic when a vehicle enters the controlled road and allows for response actions to be taken before entry.

[0041] For example, when applied to a tunnel (1), as shown in FIG. 1, the fixed frame (210) has longitudinal frames (212) installed on each side of the road and a transverse frame (211) connected to the upper parts of both longitudinal frames (212) so that guidance information can be easily recognized in the forward field of view of a vehicle driver entering the tunnel (1).

[0042] The above storage tank (220) can be installed on the upper part of the above fixed frame (210), that is, on the above transverse frame (211), and an internal space can be provided to accommodate water.

[0043] The above storage tank (220) can be supplied with or replenished with water into its internal space through a supply pipe (261), and although not shown in the drawing, a drain pipe is provided to selectively discharge the water contained in its internal space.

[0044] The above-mentioned opening / closing valve (230) may be mounted at regular intervals along the longitudinal direction on the bottom surface of the storage tank (220). For example, the above-mentioned opening / closing valve (230) may be an electronic solenoid valve that is selectively opened or closed by an operating signal input from the outside.

[0045] The discharge nozzle (240) is mounted on the opening / closing valve (230) and can discharge water in the direction of the entrance path and drop according to the opening / closing operation of the opening / closing valve (230), and the distribution pipe (221) branches from the storage tank (220) and is connected to each opening / closing valve (230), so that the water contained in the storage tank (220) can be discharged individually through each discharge nozzle (240).

[0046] Meanwhile, the control unit (30) receives guidance information output from the output unit (10) and can control the operation of the display means (200) so that the guidance information is displayed.

[0047] That is, the control unit (30) recognizes the guidance information transmitted from the output unit (10) and controls the opening and closing operation and discharge time of the individual opening and closing valve (230) to correspond to the recognized guidance information, thereby enabling the image of characters, etc., to be expressed in the form of a stream of water.

[0048] In this case, the image expressed in the form of a water stream can have a dot pattern composed of the position and timing of the water stream.

[0049] It is preferable that the opening and closing valve (230) of the above-mentioned display means (200) be mounted in multiple rows along the longitudinal direction on the bottom surface of the storage tank (220). Accordingly, the visibility of the guidance information can be improved by increasing the vertical resolution, thereby enabling detailed expression of images such as characters implemented in the form of water streams and expanding the range of such expression.

[0050] In addition, the above-mentioned opening / closing valve (230) may be an electronic solenoid valve as previously mentioned, in which case the control unit (30) can selectively adjust the degree of opening of the above-mentioned opening / closing valve (230) to control the flow rate and velocity of the discharged water.

[0051] Generally, when the shut-off valve (230) is fully opened, the water discharged through the discharge nozzle (240) falls freely due to gravity, so the water discharged from all discharge nozzles (240) falls at the same speed.

[0052] However, according to a preferred embodiment of the present invention, when the control unit (30) expresses an image of guidance information in the form of a water stream, the flow rate and velocity of the water discharged from the individual discharge nozzle (240) can be varied to change the thickness and speed of the water stream.

[0053] Accordingly, by varying the stroke thickness of images such as text, emphasis and a sense of depth can be provided to guidance information, and by changing the curved path of falling water, the rhythm and texture of movement can be expressed, thereby providing a more dynamic visual effect compared to a standard water stream method.

[0054] And the above display means (200) may further include a warning light (270) and a speaker (280) that are installed in front of the fixed frame (210), that is, in the direction viewed by the driver of a vehicle entering the controlled road, and operate in conjunction with the operation of the opening / closing valve (230).

[0055] The above warning light (270) and speaker (280) can be operated by a control signal from the control unit (30), and by outputting preset visual effects and warning sounds to attract attention, the driver of a vehicle entering the controlled road can be guided to focus on the guidance information displayed on the display means (200).

[0056] Additionally, the above-mentioned display means (200) may further include a plurality of lighting modules (290) that are installed along the longitudinal direction of the storage tank (210) at the rear of the fixed frame (210) and illuminate a stream of water that is discharged through the discharge nozzle (240) and falls downward.

[0057] That is, the above lighting module (290) shines light in a direction that follows the trajectory of the falling water stream, thereby making the outline of the water stream, which has poor visibility, clear and clearly revealing the shape of the water stream, and also induces reflection and refraction of light on the water stream to express guidance information more effectively while ensuring visibility.

[0058] Meanwhile, the situational signal input to the output unit (10) for the initiation of the above guidance information display can be input from a manager terminal (40) provided for the purpose of maintaining the road subject to control.

[0059] The above-mentioned manager terminal (40) may be provided in a control center for controlling the road subject to control and disseminating emergency situations, and may have an input means to input situational signals and transmit them to the above-mentioned output unit (10).

[0060] At this time, the above situational signal may have different signals depending on the internal and external conditions of the road to be controlled and may include unique identification information. For example, the above situational signal may include a fire occurrence signal to transmit an emergency situation due to a fire or accident inside the tunnel (1), a flood occurrence signal to transmit an emergency situation due to flooding in the underpass, or a forward lane control signal to transmit control of some lanes for traffic congestion or construction.

[0061] As previously mentioned, such situational signals may be directly input by the administrator terminal (40), but the present invention is not limited thereto, and may be linked to a server of a road traffic safety-related agency and linked to traffic situation information transmitted in real time from the agency's server, so that one of the situational signals may be selected and input.

[0062] The output unit (10) can recognize identification information included in the situational signal and select and output guidance information suitable for the recognized identification information among a plurality of previously stored guidance information.

[0063] For example, in the event of an emergency situation due to a fire or accident inside the tunnel (1), the above guidance information may be a 'stop' that blocks the entry of vehicles as shown in FIG. 4, and in the event of traffic congestion or control of some lanes for construction, the above guidance information may be a 'slow down' that induces the deceleration of vehicles.

[0064] Meanwhile, the device of the present invention can install a plurality of measurement sensors on a controlled road and display guidance information based on the results directly measured by these measurement sensors.

[0065] Specifically, the device of the present invention may further include a measurement unit (50) that detects the internal and external conditions of a controlled road and selectively generates a situational signal according to the detection result, and inputs the generated display signal to the output unit (10).

[0066] For example, the above measuring unit (50) may include various sensors capable of automatically detecting the internal and external conditions of the tunnel (1) when the road to be controlled is a tunnel (1). As shown in FIG. 5, it may include a fire detection sensor (500) that detects whether there is a fire inside the tunnel (1) and outputs a fire detection signal, a congestion detection sensor (510) that detects whether there is congestion inside the tunnel (1) and outputs a congestion detection signal, and an accident detection sensor (520) that detects whether there is an accident inside the tunnel (1) and outputs an accident detection signal.

[0067] In addition, the above measuring unit (50) may further include a height detection sensor (530) that detects the height of a vehicle traveling toward the entrance of a controlled road and outputs a height detection signal.

[0068] These garage detection sensors (530) can be applied to the entrance of bridges and urban tunnels (1) to control whether vehicles can enter based on their height.

[0069] The detection signal output from each sensor constituting the measurement unit (50) also includes unique identification information that can identify individual situations, and by inputting this together with the situation-specific signal to the output unit (10), the output unit (10) can recognize individual situations through the identification information of the input situation-specific signal.

[0070] In addition, the above measuring unit (50) is installed on the fixed frame (210) so as to face the entrance and exit of the road to be controlled, and may further include a reverse driving detection sensor (540) that recognizes the driving direction of the vehicle, detects the reverse driving of the vehicle, and outputs a reverse driving detection signal.

[0071] The output unit (10) can select and output guidance information indicating the risk of driving in reverse when a reverse driving detection signal is input according to the reverse driving detection of the reverse driving detection sensor (540).

[0072] In this case, the control unit (30) can control the operation of the display means (200) so that guidance information indicating the danger of driving in reverse is displayed through the guide unit (20) installed at the entrance / exit of the road to be controlled, rather than the display means (200) installed in the direction of entry of the road to be controlled.

[0073] Accordingly, by promptly transmitting the dangerous situation caused by a vehicle traveling in the wrong direction to the driver of a vehicle in the normal entry lane of the controlled road, it is possible to prevent or prepare for accidents such as collisions with vehicles entering from that direction, thereby minimizing casualties.

[0075] Although preferred embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and improvements by those skilled in the art using the basic concept of the present invention as defined in the following claims also fall within the scope of the present invention.
