Description

Technology Field

[0001] The present invention relates to a vehicle underpass notification system, and more specifically, to a vehicle underpass notification system that can accurately inform a driver whether their vehicle can pass a height restriction structure located ahead, thereby preventing accidents caused by the vehicle colliding with or getting stuck on the height restriction structure. Background Technology

[0002] Among various types of roads, such as overpasses, riverside roads, underpasses, railways, and underground parking lots, there are many places where barriers are installed to limit the height of passing vehicles. Consequently, when a vehicle with a heavy load travels on a road where vehicle height is restricted, there is a constant risk that the cargo vehicle may collide with the barrier installed on the road surface, as the driver may not be able to determine the height of the barrier in advance upon entering the road.

[0003] To prevent such risks, bridges and underpasses that currently restrict vehicle height display entry warning signs on the front of the facilities, indicating height limits such as 2.7 M or 3.4 M. However, actual drivers frequently witness accidents caused by drivers misjudging the height of their vehicles and attempting to pass through without stopping. Furthermore, accidents frequently occur where vehicles get stuck in or scratched by height restriction facilities, resulting in damage to cargo on top. Prior art literature

Brief explanation of the drawing

[0016] FIG. 1 is a configuration diagram of a vehicle underpass notification system according to an embodiment of the present invention. FIG. 2 is a drawing of a first support, a second support, and a sensor part according to an embodiment of the present invention. FIG. 3 is a rear view illustrating the state of detecting the height of a vehicle through a vehicle underpass notification system according to an embodiment of the present invention. Specific details for implementing the invention

[0017] As shown in FIGS. 1 to 3, the vehicle underpass notification system of the present invention comprises a height limiting structure (1), a first support (2), a second support (3), a sensor unit (4), a warning display member (5), and a control unit (not shown).

[0018] The above height limiting structure (1) is installed at the entrance of a tunnel, underpass, underground parking lot, etc., to limit the height of vehicles passing through.

[0019] Therefore, the moving vehicle passes under the height limiting structure (1).

[0020] The first support member (2) is formed in a column shape and is installed in front of the height limiting structure (1).

[0021] The second support member (3) is formed in a column shape and is installed between the first support member (2) and the height limiting structure (1).

[0022] As shown in FIGS. 2 and 3, the sensor unit (4) is mounted on the first support (2) and the second support (3) to measure the height of the moving vehicle.

[0023] The sensor unit (4) is composed of a first lower sensor (41), a first upper sensor (42), a second lower sensor (43), and a second upper sensor (44).

[0024] The first lower sensor (41) is mounted lower than the first upper sensor (42) on the first support (2) to measure the height of the moving vehicle.

[0025] The first upper sensor (42) is mounted on the upper part of the first lower sensor (41) on the first support (2) to measure the height of the moving vehicle.

[0026] The second lower sensor (43) is mounted lower than the second upper sensor (44) on the second support (3) to measure the height of the moving vehicle.

[0027] The second upper sensor (44) is mounted on the upper part of the second lower sensor (43) on the second support (3) to measure the height of the moving vehicle.

[0028] The first lower sensor (41) and the second lower sensor (43) are positioned at the same height, and the first upper sensor (42) and the second upper sensor (44) are positioned at the same height.

[0029] Accordingly, the first lower sensor (41) and the second lower sensor (43) measure the same height of the moving vehicle, and the first upper sensor (42) and the second upper sensor (44) measure the same height of the moving vehicle.

[0030] The above warning indicator member (5) is installed between the second support (3) and the height limiting structure (1) and / or on the height limiting structure (1).

[0031] The above warning indicator (5) can be displayed using a lamp, sound, screen, etc.

[0032] The above warning indicator member (5) may be installed in multiple numbers as shown in FIG. 1.

[0033] When the above control unit detects a moving vehicle through the sensor unit (4), it informs the outside through the warning display member (5) whether the vehicle can pass through the height restriction structure (1) according to the input value of the sensor unit (4).

[0034] The control unit determines that if a vehicle is not detected by the first lower sensor (41) and the second lower sensor (43), the vehicle can pass through the height restriction structure (1), and thus does not activate the warning indicator member (5) or causes the warning indicator member (5) to indicate permission for the vehicle to pass.

[0035] And, if a vehicle is detected by the first lower sensor (41) and the second lower sensor (43) and not by the first upper sensor (42) and the second upper sensor (44), the control unit informs the vehicle to exercise caution when passing through the height limit structure (1) via the warning indicator member (5) located at the front.

[0036] In addition, when a vehicle is detected by the first upper sensor (42) and the second upper sensor (44), the control unit notifies the vehicle of a prohibition of passage through the warning indicator member (5) so that the vehicle cannot pass through the height restriction structure (1).

[0037] At this time, when the first upper sensor (42) and the second upper sensor (44) detect a vehicle, the first lower sensor (41) and the second lower sensor (43) also naturally detect a vehicle.

[0038] With the system of the present invention as described above, the driver can easily recognize whether their vehicle can pass through the height limiting structure (1) located in front.

[0039] The present invention may further include a solar module mounted on the first support (2) and / or the second support (3).

[0040] At this time, the sensor unit (4), warning indicator member (5), or control unit is operated by electricity produced from the solar module.

[0041] The sensor unit (4) may also measure the speed of a moving vehicle.

[0042] At this time, it is preferable that the sensor unit (4) be composed of a LiDAR sensor, etc.

[0043] The control unit calculates the time for the vehicle to reach the warning indicator member (5) based on the speed of the vehicle measured by the second lower sensor (43) or the second upper sensor (44) mounted on the second support member (3), and then indicates whether the vehicle can pass at the warning indicator member (5) at the calculated time.

[0044] Through this, the warning indicator member (5) indicates whether the vehicle can pass through the height restriction structure (1) when the vehicle is right in front of it, thereby allowing the driver to better know whether their vehicle can pass through the height restriction structure (1) without confusing it with other vehicles.

[0045] And, the control unit calculates the time for the vehicle to reach the second support (3) based on the speed of the vehicle measured by the first lower sensor (41) or the first upper sensor (42), and if the vehicle is not detected by the second lower sensor (43) and the second upper sensor (44) within the calculated time range, it notifies the administrator or the warning indicator member (5) that there is a system failure.

[0046] This allows you to identify system malfunctions and take prompt action.

[0047] In addition, the sensor unit (4) may also detect the license plate of a moving vehicle.

[0048] At this time, the control unit displays the license plate of the corresponding vehicle on the warning display member (5).

[0049] Through this, the driver can more accurately determine whether their vehicle can pass through the height restriction structure (1) by checking the pass signal displayed together with their vehicle number.

[0050] In addition, the control unit may receive information from an external disaster management server that manages floods, heavy rain, heavy snow, earthquakes, etc., and notify the outside of such information through the warning display member (5).

[0051] Through this, vehicles can be prevented from entering underpasses, tunnels, etc. located behind the height restriction structure (1), and various functions can be implemented through the warning indicator member (5) of the present invention.

[0052] Meanwhile, when a vehicle is detected by the first upper sensor (42) and the second upper sensor (44), the control unit transmits a signal to the smartphone of the driver or owner of the vehicle to automatically activate an alarm warning sound indicating that the vehicle cannot pass.

[0053] This allows the driver and others to more accurately recognize that their vehicle must not pass through the height restriction structure (1).

[0054] As described above, the present invention has the effect of preventing an accident in advance by accurately notifying the driver whether their vehicle can pass through a height restriction structure (1) located in front, thereby preventing the vehicle from colliding with or getting stuck on the height restriction structure (1).

[0055] The vehicle underpass notification system of the present invention is not limited to the aforementioned embodiments and can be implemented with various modifications within the scope permissible by the technical concept of the present invention. Explanation of the symbols
