Description

Technology Field

[0001] The present invention relates to a speed guidance system that provides vehicle speed information and safety guidance information for a vehicle passing through a speed enforcement zone. More specifically, the invention relates to a system that generates safety driving information to guide safe driving of a vehicle based on the vehicle speed of a vehicle passing through a speed enforcement zone, and outputs one or more of vehicle speed information, safety driving information, and vehicle registration number information to a display board device to guide safe driving of a vehicle passing through a speed enforcement zone and prevent accidents. Background Technology

[0002] Traffic accidents involving automobiles are extremely fatal, instantly taking away not only massive property damage but also precious lives. In particular, unlike simple signal violations or minor collisions, accidents caused by speeding often result in casualties. Therefore, in order to reduce vehicle speeds and accidents caused by speeding, police officers have used speed guns to measure the speed of moving vehicles on the road and crack down on speeding vehicles on the spot; however, direct enforcement at the scene presents many safety issues.

[0003] Therefore, as an idea to reduce the driving speed of vehicles, speed bumps, model traffic police officers, and mock cameras are installed, or unmanned cameras for catching speeding vehicles are installed to raise awareness among drivers and prevent speeding.

[0004] Unmanned cameras for catching speeding vehicles are utilized as a method to indirectly prevent speeding by taking photos of the license plate, date of violation, and speed of violation when a moving vehicle exceeds the speed limit, and using this as evidence when imposing a fine.

[0005] However, to avoid such speed enforcement, drivers of vehicles accelerate after passing unmanned cameras for speed enforcement and drive at speeds exceeding the speed limit.

[0006] Accordingly, although vehicles drive at the regulated speed due to unmanned cameras for speed enforcement, there is a problem in that vehicles only drive at the regulated speed in the enforcement zone where they are caught by the unmanned cameras, and after passing the enforcement zone, they instead accelerate rapidly and speed, which actually causes accidents.

[0029] FIG. 1 is a diagram showing the connections between the components of a speed guidance system that provides vehicle speed information and safety guidance information for a vehicle passing through a speed enforcement section according to an embodiment of the present invention; FIG. 2 is a block diagram of the components of a speed guidance system that provides vehicle speed information and safety guidance information for a vehicle passing through a speed enforcement section according to an embodiment of the present invention; FIG. 3 is a drawing showing the front view of a road where a speed guidance system that provides vehicle speed information and safety guidance information for a vehicle passing through a speed enforcement section according to an embodiment of the present invention is installed; FIG. 4 is a drawing showing the upper view of a road where a speed guidance system that provides vehicle speed information and safety guidance information for a vehicle passing through a speed enforcement section according to an embodiment of the present invention is installed; and FIG. 5 is a drawing showing the side view of a road where a speed guidance system that provides vehicle speed information and safety guidance information for a vehicle passing through a speed enforcement section according to an embodiment of the present invention is installed.

[0030] Referring to FIGS. 1 to 5, an overspeed guidance system (hereinafter referred to as the "overspeed guidance system") that provides vehicle speed information and safety guidance information for a vehicle passing through an overspeed enforcement section according to one embodiment of the present invention may include a vehicle information acquisition device (100), a control device (200), and an electronic display device (300).

[0031] A vehicle information acquisition device (100) can be installed on a road where a vehicle is traveling.

[0032] Specifically, the vehicle information acquisition device (100) may be installed on one side of the road to measure the speed of a vehicle traveling on the road, take an image of the vehicle, and acquire the vehicle registration number of the vehicle.

[0033] Here, as described above, the road is a path for vehicles to travel on, and lanes and a center lane may be formed to allow vehicles to travel in different directions, and crosswalks may be formed to allow pedestrians to cross.

[0034] In addition, vehicle traffic lights (L1) and pedestrian traffic lights (L2) may be installed on the road to prevent collisions between vehicles or between vehicles and pedestrians when vehicles and pedestrians pass.

[0035] In addition, the speed limit on the aforementioned road may be set in accordance with the Road Traffic Act.

[0036] Such a speed limit may refer to the maximum speed at which a vehicle can travel on that road.

[0037] At this time, a vehicle speed enforcement device (E) may be installed on the road to monitor whether a vehicle is traveling at a speed exceeding the speed limit, that is, to monitor whether a vehicle is speeding.

[0038] Such vehicle speed enforcement equipment (E) can enforce speeding against vehicles traveling in a speed enforcement section (AR1) on the road. For example, the vehicle speed enforcement equipment (E) may be conventional equipment installed and operated by the police.

[0039] Meanwhile, the vehicle information acquisition device (100) can generate vehicle speed information by measuring the vehicle speed of a vehicle that has passed through the speed enforcement section (AR1) among vehicles driving on the road.

[0040] That is, the vehicle information acquisition device (100) can generate vehicle speed information by measuring the vehicle speed of a vehicle traveling in the subsequent section (AR2) of the speed enforcement section (AR1) after passing through the speed enforcement section (AR1).

[0041] Additionally, the vehicle information acquisition device (100) can generate vehicle speed information by measuring the vehicle speed of a vehicle traveling in a preceding section, which is a section prior to the speed enforcement section (AR1).

[0042] At this time, the vehicle can pass through the speed enforcement section (AR1) after passing the preceding section, and enter the following section (AR2) after passing through the high-speed enforcement section (AR1).

[0043] Here, the starting point of the subsequent section (AR2) is the same as the ending point of the speed enforcement section (AR1), and the ending point of the subsequent section (AR2) is separated by a predetermined distance from the starting point of the subsequent section (AR2), and the ending point of the preceding section is the same as the starting point of the speed enforcement section (AR1), and the starting point of the preceding section may be separated by a predetermined distance from the ending point of the preceding section.

[0044] To this end, the vehicle information acquisition device (100) may be equipped with a radar module for measuring speed.

[0045] Additionally, the vehicle information acquisition device (100) can generate vehicle registration number information by identifying the vehicle registration number from a vehicle that has passed through the speed enforcement section (AR1).

[0046] That is, the vehicle information acquisition device (100) can generate vehicle registration number information by identifying the vehicle registration number from a vehicle traveling in the subsequent section (AR2) of the speed enforcement section (AR1) after passing through the speed enforcement section (AR1).

[0047] Specifically, the vehicle information acquisition device (100) can generate a vehicle image by photographing a vehicle traveling in a subsequent section (AR2) of the speed enforcement section (AR1) after passing through the speed enforcement section (AR1), extract a vehicle license plate image from a vehicle license plate area in which a vehicle license plate is photographed among the vehicle images, and generate vehicle registration number information by identifying the vehicle registration number from the vehicle license plate image using a character identification algorithm.

[0048] To this end, the vehicle information acquisition device (100) may be equipped with a camera module for capturing an image, an image editing module for extracting an image of a specific area from the image, and a character identification algorithm for identifying a number from the image.

[0049] Meanwhile, the vehicle information acquisition device (100) can transmit the acquired vehicle information (vehicle speed information, vehicle registration number information) to the control device (200).

[0050] FIG. 6 is a diagram illustrating an artificial intelligence model included in a vehicle information acquisition device of a speed guidance system that provides vehicle speed information and safety guidance information of a vehicle that has passed through a speed enforcement section according to one embodiment of the present invention.

[0051] Referring to FIG. 6, the vehicle information acquisition device (100) can acquire vehicle registration number information based on a vehicle license plate image.

[0052] Specifically, the vehicle information acquisition device (100) inputs a vehicle license plate image (D) as input data to an artificial intelligence model (M) trained to identify characters and numbers from an image, and receives vehicle registration number information (I), which is the result of identifying the vehicle registration number from the artificial intelligence model (M), as output data.

[0053] At this time, the vehicle information acquisition device (100) can configure training data for training an artificial intelligence model (M) and use the configured training data to train the artificial intelligence model (M) to identify characters and numbers from an image.

[0054] To this end, the vehicle information acquisition device (100) can be configured as training data by matching a training vehicle license plate image prepared for the learning of an artificial intelligence model (M) and a training vehicle registration number information, which is the actual vehicle registration number of the vehicle represented by the training vehicle license plate image.

[0055] That is, when a vehicle enters the subsequent section (AR2), the vehicle information acquisition device (100) captures the vehicle to generate a vehicle image, extracts a vehicle license plate area containing the vehicle license plate from the vehicle image as a vehicle license plate image, and inputs the vehicle license plate image as input data to an artificial intelligence model (M), thereby receiving vehicle registration number information (I), which is the result of identifying the vehicle registration number, as output data from the artificial intelligence model (M).

[0056] Referring again to FIGS. 1 to 5, the control device (200) generates safety driving guidance information that induces safe driving of the vehicle based on vehicle speed information, and can control the display device (300) so that the display device (300) outputs one or more of the vehicle speed information, vehicle registration number information and safety driving guidance information.

[0057] At this time, the control device (200) can control the electronic display device (300) by transmitting one or more of vehicle speed information, vehicle registration number information, and safe driving guidance information to the electronic display device (300), and also transmitting a control signal to the electronic display device (300).

[0058] Below, the process of the control device (200) generating safe driving guidance information will be explained in detail.

[0059] First, when the control device (200) receives vehicle speed information from the vehicle information acquisition device (100) indicating the vehicle speed of a vehicle traveling in the subsequent section (AR2) of the speed enforcement section (AR1) after passing through the speed enforcement section (AR1), it can determine whether the vehicle speed indicated by the received vehicle speed information exceeds the speed limit set on the road.

[0060] Here, the speed limit may refer to the maximum speed at which a vehicle can travel in accordance with the Road Traffic Act.

[0061] Afterward, the control device (200) can generate safe driving guidance information based on the result of determining whether the vehicle speed indicated by the vehicle speed information exceeds the speed limit.

[0062] Specifically, the control device (200) can generate one or more of the following as safe driving guidance information: overspeed notification information indicating that the vehicle speed is overspeeding when the vehicle speed exceeds the speed limit, and deceleration guidance information inducing the vehicle speed to decelerate.

[0063] For example, the speed warning information may be text information containing “speeding,” and the deceleration induction information may be text information containing “decelerate” or “reduce speed.”

[0064] Conversely, if the vehicle speed is below the speed limit, the control device (200) can generate one or more of the following as safe driving guidance information: speed compliance notification information indicating that the vehicle speed is complying with the speed limit and the speed maintenance guidance information inducing the vehicle to maintain its speed.

[0065] For example, speed compliance notification information may be text information containing “speed compliance,” and speed maintenance guidance information may be text information containing “maintain speed” or “maintain speed.”

[0066] Meanwhile, the control device (200) can control the display device (300) to output vehicle speed information, vehicle registration number information, and safety driving guidance information while transmitting the vehicle speed information, vehicle registration number information, and safety driving guidance information to the display device (300) when the vehicle travels in the subsequent section (AR2).

[0067] At this time, the control device (200) can control the display device (300) so that when the vehicle speed exceeds the speed limit, the display device (300) outputs vehicle speed information in a preset first color.

[0068] Conversely, the control device (200) can control the display device (300) so that if the vehicle speed is below the speed limit, the display device (300) outputs vehicle speed information in a preset second color.

[0069] For example, the first color may be red and the second color may be green.

[0070] To this end, the control device (200) can include color information in the control signal and transmit it to the display device (300).

[0071] Meanwhile, a control device (200) according to another embodiment can calculate first acceleration information representing the acceleration of a vehicle traveling from the starting point of the following section (AR2) to the middle point of the following section (AR2) by using first vehicle speed information representing the vehicle speed of a vehicle at the starting point of the following section (AR2) and second vehicle speed information representing the vehicle speed of a vehicle traveling at the middle point of the following section (AR2).

[0072] Here, the midpoint of the subsequent section (AR2) may be the midpoint between the start point of the subsequent section (A2) and the end point of the subsequent section (A2).

[0073] Afterwards, the control device (200) can use the first acceleration information to generate maximum speed information indicating the expected maximum speed of the vehicle while the vehicle travels from the midpoint of the trailing section (AR2) to the end point.

[0074] At this time, the control device (200) can generate the vehicle's speed as maximum speed information when the vehicle reaches the end point of the following section (AR2) while maintaining the acceleration indicated by the first acceleration information from the midpoint of the following section (AR2).

[0075] Next, the control device (200) can generate overspeed prediction information as safe driving guidance information indicating that overspeeding is expected when the maximum speed indicated by the maximum speed information exceeds the speed limit.

[0076] For example, the speeding prediction information may be text information containing “speeding prediction”.

[0077] Through this, the control device (200) can notify the driver of a vehicle that speeding is expected due to rapid acceleration while driving in the following section (AR2), even if the current speed of the vehicle is below the speed limit.

[0078] Meanwhile, a control device (200) according to another embodiment may add vehicle registration number information of a vehicle to a high-risk vehicle list based on second acceleration information representing the acceleration of a vehicle that has traveled in a preceding section of the speed enforcement section (AR1) and the first acceleration information described above.

[0080] Specifically, the control device (200) can calculate second acceleration information representing the acceleration of the vehicle using third vehicle speed information representing the vehicle speed at the starting point of the preceding section and fourth vehicle speed information representing the vehicle speed at the ending point of the preceding section.

[0081] Afterwards, the control device (200) can calculate a first acceleration ratio, which is the ratio of the acceleration represented by the first acceleration information to the first reference acceleration, and a second acceleration ratio, which is the ratio of the acceleration represented by the second acceleration information to the second reference acceleration.

[0082] Next, the control device (200) can add the vehicle registration number information of the vehicle to the high-risk vehicle list if the sum of the first acceleration ratio and the second acceleration ratio exceeds the reference acceleration ratio.

[0083] When the control device (200) detects that a vehicle with a vehicle registration number of the vehicle registration number information registered in the high-risk vehicle list has entered the speed enforcement zone (AR2), it can generate high-risk vehicle notification information indicating that a high-risk vehicle has entered the speed enforcement zone (AR2).

[0084] Afterwards, the control device (200) can transmit high-risk vehicle alert information to an auxiliary display device.

[0085] The auxiliary display device is a device that outputs information by being located near a crosswalk installed within a speed enforcement zone (AR2), and, for example, can be installed next to a traffic light for a crosswalk to provide information to pedestrians.

[0086] Specifically, when the auxiliary display unit receives high-risk vehicle alert information from the control unit (200), it can display the high-risk vehicle alert information using one or more of numbers, letters, symbols, and codes.

[0087] For example, the auxiliary display unit can display the phrase “High-risk vehicle entry” on the screen when high-risk vehicle alert information is received.

[0088] Through this, the control device (200) can notify the driver of a vehicle that speeding is expected due to rapid acceleration while driving in the following section (AR2), even if the current speed of the vehicle is below the speed limit.

[0089] FIG. 7 is a drawing for explaining an example of an electronic display device of a speed guidance system that provides vehicle speed information and safety guidance information for a vehicle passing through a speed enforcement section according to one embodiment of the present invention, and FIG. 8 is a drawing for explaining another example of an electronic display device of a speed guidance system that provides vehicle speed information and safety guidance information for a vehicle passing through a speed enforcement section according to one embodiment of the present invention, that provides information.

[0090] Referring to FIGS. 7 and 8, the display device (300) can be positioned above the road to display information so that the driver of a vehicle traveling on the road can check the displayed information.

[0091] Specifically, the display device (300) can be positioned above the subsequent section (AR2) so that the driver of a vehicle traveling in the subsequent section (AR2) of the speed enforcement section (AR1) after passing through the speed enforcement section (AR1) can check the information displayed.

[0092] That is, the vehicle passes through the preceding section and then enters the speed enforcement section (AR1) and drives through the speed enforcement section (AR1). When passing through the speed enforcement section (AR1), it can enter the following section (AR2), drive through the following section (AR2), and then pass through the following section (AR2).

[0093] Such an electronic display device (300) can display one or more of vehicle speed information, vehicle registration number information and safe driving guidance information, one or more of numbers, letters, symbols and signs.

[0094] Specifically, as shown in FIG. 7, the vehicle information acquisition device (100) can output vehicle speed information (I1), overspeed notification information (I2) indicating that the vehicle speed is overspeeding, deceleration induction information (I3) inducing the vehicle speed to decelerate, and vehicle registration number information (I4) when the vehicle speed exceeds the speed limit.

[0095] Through this, it is possible to guide the speeding and rapid acceleration of a vehicle that speeds in the subsequent section (AR2) of the speed enforcement section (AR1) after passing through the speed enforcement section (AR1) by avoiding the speed enforcement of the speed enforcement equipment (E).

[0096] Conversely, as illustrated in FIG. 8, if the vehicle speed is below the speed limit, the display device (300) can output vehicle speed information (I5), speed compliance notification information (I6) indicating that the vehicle speed is below the speed limit and that the speed limit is being observed, speed maintenance guidance information (I7) encouraging the vehicle to maintain its speed, and vehicle registration number information (I8).

[0097] Through this, even if the vehicle passes through the speed enforcement zone (AR1), the driver can be guided to comply with the speed limit in the subsequent section (AR2) of the speed enforcement zone (AR1).

[0098] Hereinafter, the configurations of the vehicle information acquisition device (100) will be described.

[0099] The vehicle information acquisition device (100) may include a processor, a storage unit, and a communication unit.

[0100] The processor can control the overall operation of the vehicle information acquisition device (100) using various programs stored in the storage unit included in the vehicle information acquisition device (100). The processor may be composed of RAM, ROM, a graphics processing unit, a main CPU, first to n interfaces, and a bus. At this time, the RAM, ROM, graphics processing unit, main CPU, first to n interfaces, etc., may be connected to each other through a bus.

[0101] RAM stores the O / S and application programs. Specifically, when the vehicle information acquisition device (100) boots up, the O / S is stored in RAM, and various application data selected by the user can be stored in RAM.

[0102] A set of instructions for booting is stored in the ROM. When a turn-on command is input and power is supplied, the main CPU copies the O / S stored in the storage unit to the RAM according to the instructions stored in the ROM, and executes the O / S to boot. When booting is complete, the main CPU copies various application programs stored in the storage unit (150) to the RAM, and executes the application programs copied to the RAM to perform various operations.

[0103] The main CPU accesses the storage unit and performs booting using the OS stored therein. Additionally, the main CPU performs various operations using various programs, content, and data stored in the storage unit.

[0104] The first to n interfaces are connected to the various components described above. One of the first to n interfaces may be a network interface connected to an external device through a network.

[0105] Meanwhile, the processor may include one or more cores (not shown) and a graphics processing unit (not shown) and / or a connection channel (e.g., a bus, etc.) for transmitting and receiving signals with other components.

[0106] Meanwhile, the processor may further include RAM (Random Access Memory, not shown) and ROM (Read-Only Memory, not shown) for temporarily and / or permanently storing signals (or data) processed within the processor. Additionally, the processor may be implemented in the form of a system-on-chip (SoC) that includes at least one of a graphics processing unit, RAM, and ROM.

[0107] The storage unit can store various programs and data required for the operation of the vehicle information acquisition device (100). The storage unit may be implemented as non-volatile memory, volatile memory, flash memory, hard disk drive (HDD), or solid-state drive (SSD).

[0108] The storage unit can store programs (one or more instructions) for processing and controlling the processor. The programs stored in the storage unit can be divided into multiple modules according to their function.

[0109] The communication unit can communicate with other devices. In particular, the communication unit may include various communication chips such as Wi-Fi chips, Bluetooth chips, wireless communication chips, NFC chips, and low-power Bluetooth chips (BLE chips). In this case, the Wi-Fi chip, Bluetooth chip, and NFC chip perform communication using LAN, Wi-Fi, Bluetooth, and NFC methods, respectively. When using a Wi-Fi chip or a Bluetooth chip, various connection information such as SSID and session key is transmitted and received first, and after establishing a communication connection using this information, various information can be transmitted and received. A wireless communication chip refers to a chip that performs communication according to various communication standards such as IEEE, Zigbee, 3G (3rd Generation), 3GPP (3rd Generation Partnership Project), LTE (Long Term Evolution), and 5G (1st Generation).
