Description

Technology Field

[0001] The present invention relates to an artificial intelligence-based pedestrian safety light and a notification method thereof, which can prevent accidents at a crosswalk in advance by detecting a pedestrian at the crosswalk and illuminating the underground light, by supplying power generated through a solar power generation device to a camera, photographing a crosswalk area to determine whether a pedestrian is crossing, selectively transmitting an underground light illumination control signal according to the determination result, and causing the underground light device to illuminate when the underground light illumination control signal is transmitted. Background Technology

[0002] As is well known, on roads where vehicles travel, crosswalk markings are placed on the road surface to allow pedestrians to cross safely, and traffic lights are installed to regulate the flow of traffic, thereby ensuring that pedestrians can cross safely.

[0003] In addition, on roads with relatively low traffic volume or quiet conditions, separate traffic lights are not installed; instead, only crosswalk markings are provided. Pedestrians observe the flow of traffic and cross the road via the crosswalk only when no vehicles are passing, while drivers are required to stop and wait at the crosswalk when pedestrians are present, resuming their journey once the pedestrian has fully crossed the road.

[0004] Meanwhile, at crosswalks at night, in remote and dark areas, or during rain or snow, it is extremely difficult for drivers to identify pedestrians crossing and stop their vehicles; furthermore, since the installation locations of crosswalks are often difficult to identify, they always carry a high risk of accidents.

[0005] Accordingly, various technologies are being developed to prevent accidents by installing streetlights and separate lighting devices around crosswalks to indicate their location and enable drivers to clearly identify pedestrians, while technologies that integrate power generation devices using renewable energy into these systems are also being developed.

Specific details for implementing the invention

[0021] The advantages and features of the embodiments of the present invention, and the methods for achieving them, will become clear by referring to the embodiments described below in detail together with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below but may be implemented in various different forms. These embodiments are provided merely to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the invention, and the present invention is defined only by the scope of the claims. Throughout the specification, the same reference numerals refer to the same components.

[0022] In describing the embodiments of the present invention, specific descriptions of known functions or configurations will be omitted if it is determined that such detailed descriptions could unnecessarily obscure the essence of the invention. Furthermore, the terms described below are defined in consideration of their functions in the embodiments of the present invention, and these definitions may vary depending on the intentions or practices of the user or operator. Therefore, such definitions should be based on the content throughout this specification.

[0023] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings.

[0024] FIG. 1 is a block diagram showing an artificial intelligence-based pedestrian safety light according to an embodiment of the present invention, FIG. 2 is a schematic illustration of an artificial intelligence-based pedestrian safety light according to an embodiment of the present invention, FIG. 3 and FIG. 4 are drawings for explaining series-parallel switching in an artificial intelligence-based pedestrian safety light according to an embodiment of the present invention, and FIG. 5 and FIG. 6 are drawings for explaining the form of an underground light in an artificial intelligence-based pedestrian safety light according to an embodiment of the present invention.

[0025] Referring to FIGS. 1 to 6, an artificial intelligence-based pedestrian safety light according to one embodiment of the present invention may include a solar power generation device (100), an energy storage device (200), a camera (300), an underground light device (400), etc.

[0026] The solar power generation device (100) generates power using at least one solar panel (110) provided on the upper part of a support post installed on the side of a crosswalk, and may include at least one solar panel (110), a grid output unit (120), a switching unit (130), a power generation control unit (140), etc.

[0027] Here, at least one solar panel (110) can generate power by concentrating sunlight. An illuminance sensor may be provided on the upper surface of such solar panel (110), allowing for real-time monitoring of the generated power in response to the illuminance value measured during initial installation. After defining an algorithm for the voltage difference between the measured illuminance value and the solar panel (110), the operating state of the solar panel (110) can be diagnosed (e.g., occurrence of cracks, occurrence of contamination, etc.) through monitoring before and after the inverter (122) provided in the grid output unit (120), thereby enabling active response to the prevention and diagnosis of damage to the solar panel.

[0028] And, the grid output unit (120) outputs power generated through the solar panel (110) to the grid line and can perform a maximum power point tracking (MPPT) function by including a voltage detector (121), at least one inverter (122), etc.

[0029] Here, the voltage sensor (121) can measure the power value of the power generated through each solar panel (110) and provide it to the power generation control unit (140).

[0030] And, at least one inverter (122) has an MPPT function to obtain maximum power generation using a solar panel (110), and can adjust voltage and current output conditions to a value that can produce maximum output.

[0031] Accordingly, the inverter (122) may stop operating when the output power value of the solar panel (110) is relatively lower than the maximum output point, according to MPPT control that enables operation when the maximum output point is higher.

[0032] For example, during times when the intensity of sunlight is weak, such as cloudy weather, just before sunset, or just after sunrise, the output power value of the solar panel (110) is lower than the maximum output point, so the operation of the corresponding inverter may be stopped, and the output power may be switched in series and parallel to the rear end of another solar panel of an adjacent (or nearby) solar power generation device through the switching unit (130), and through this, the output power of both sides may be added together and stored.

[0033] Additionally, the switching unit (130) can perform series and parallel switching by connecting the solar panel (110) and the grid output unit (120) or by connecting the rear end of another solar panel of another solar power generation device, and can switch to output power to another station when the voltage value of the power is lower than a preset power value according to the control of the power generation control unit (140).

[0034] The operation of such a switching unit (130) will be explained in detail in the description of the operation of the switching control of the power generation control unit (140) described later.

[0035] Meanwhile, the power generation control unit (140) controls the operation of at least one solar panel (110), a grid output unit (120), and a switching unit (130), and controls the power generated through the solar panel (110) to be stored in an energy storage device (200), and controls the power stored in the energy storage device (200) to be supplied to a shooting device (300) and an underground lighting device (400).

[0036] And, the power generation control unit (140) receives the voltage value of the power generated through the solar panel (110) and can control switching to output power to another solar panel if it is lower than a preset power value.

[0037] For example, referring to FIGS. 3 and 4, the series-parallel switching control of power is described. FIG. 3 shows a state in which each solar panel (110a, 110b) and each grid output unit (120a, 120b) are connected in correspondence with each other when the output power value of the solar panel (110a) is formed to be greater than or equal to the maximum output point of the grid output unit (120a).

[0038] And, FIG. 4 shows a state in which, when the output power value of the solar power (110a) is formed to be below the maximum output point of the grid output unit (120a), the solar panel (110a) provided in one solar power generation device (100a) is switched to the rear end of another solar panel (110b) provided in another solar power generation device (100b) and connected to another grid output unit (120b).

[0039] That is, power generated through one solar panel (110a) and another solar panel (110b) can be stored in a battery (131) provided in an energy storage unit (130) through a grid output unit (120b) provided in another solar power generation device (100b). Of course, even in this case, if the combined output power value of the two is below the maximum output point, the operation of the inverter provided in the corresponding grid output unit (120a, 120b) can be stopped.

[0040] As described above, in the embodiment of the present invention, switching control is explained as being performed using two photovoltaic power generation devices (100a, 100b) in which photovoltaic panels (111a, 111b) are each connected in series; however, it is understood that switching control can be performed in a similar manner even when four different sectors are configured and multiple photovoltaic power generation devices are configured in each sector. That is, when two or three output power values ​​are below the maximum output point, the output of the renewable energy generation unit of four sectors can be switched to one sector and converted into a single output.

[0041] In addition, the switching control in the embodiment of the present invention as described above can be performed through various series-parallel connections, such as a parallel mode, a two-location series mode, and a three-location series mode.

[0042] The energy storage device (200) stores power generated through the solar power generation device (100) and may include a battery (210), a battery manager (220), a power manager (230), a power converter (240), etc.

[0043] Here, the battery (210) stores power generated through the solar power generation device (100), and can store direct current energy in the form of chemical energy, including a fuel cell.

[0044] And, the battery manager (220) can manage the internal state of the battery (210) including a battery management system (BMS).

[0045] Additionally, the power manager (230) can manage the power storage system and supply system, including the power management system (PMS), and can execute an internal control algorithm by receiving real-time input of information on the power system, battery charge status, load status, etc., and thereby transmit control commands for charging (storage) operation or discharging (supply) operation to the battery (210).

[0046] Meanwhile, the power converter (240) includes a power conditioning system (PCS) including a converter and an inverter, and converts the AC power output through the grid output unit (120) into DC power to store (charge) in the battery (210), and converts the DC power stored in the battery (210) into DC or AC power to supply to the shooting device (300) and the underground lighting device (400), respectively. For example, the DC-DC converter can adjust the voltage level of the power and output it, and the DC-AC inverter can convert the power into AC power and output it.

[0047] The shooting device (300) is equipped to photograph a crosswalk area on a support post and operates using power supplied from an energy storage device (200). It photographs the crosswalk area to determine whether a pedestrian is crossing and selectively transmits an underground light light control signal according to the result of the determination. The underground light light control signal can be transmitted to an underground light device according to a Bluetooth Mesh communication method and may include an object recognition camera (310), a camera control unit (320), a communication module unit (330), etc.

[0048] Here, the object recognition camera (310) can transmit captured video data including CCTV (closed circuit television), and can photograph pedestrians in the crosswalk area under the control of the camera control unit (320).

[0049] This object recognition camera (310) can operate functions such as pan, tilt, and zoom according to the control of the camera control unit (320) to more effectively photograph pedestrians in the crosswalk area.

[0050] In addition, the camera control unit (320) can control the object recognition camera (310), identify and detect artificial intelligence objects, and control the underground light device (400).

[0051] For example, the camera control unit (320) can identify and detect pedestrians using artificial intelligence in video data transmitted through the object recognition camera (310). It can determine whether a pedestrian is detected using artificial intelligence in video data capturing a crosswalk area, and if a pedestrian is detected, it can generate an underground light illumination control signal and transmit it to the underground light device (400) through the communication module unit (330). Of course, if no pedestrian is detected, normal camera control can be performed.

[0052] Here, artificial intelligence can utilize convolutional neural network (CNN) models, and among them, algorithms such as the single-shot multibox detector (SSD), which offers fast object detection speeds, and the Faster R-CCN ​​algorithm, which offers high object detection accuracy, can be used.

[0053] Additionally, the camera control unit (320) can transmit an operation control signal to the underground lighting device (400) through the communication module unit (330) to turn off or turn on the light according to a preset time range including daytime and evening time. The preset time range can be set as daytime (e.g., 7:00 AM to 7:00 PM), evening time (e.g., 7:00 PM to 7:00 AM), etc., and since sunrise and sunset times differ depending on the four seasons such as spring, summer, autumn, and winter, the time range can be set by taking these factors into account.

[0054] In addition, the camera control unit (320) receives the current illuminance value through the illuminance sensor installed in the solar power generation device (100) while the underground light device (400) is turned off or on according to a preset time range, compares it with a preset reference illuminance value, and if the value is relatively smaller than the preset reference illuminance value (e.g., on a rainy day, a snowy day, a cloudy day, etc.), it can transmit an emergency lighting control signal to the underground light device (400) through the communication module unit (330) to turn on the underground light in an emergency.

[0055] Here, the camera control unit (320) can transmit an operation control signal to the underground light device (300) through the communication module unit (330) to emit light in one color at a time when the light is turned on according to a preset time range, and can transmit an underground light light emission control signal to the underground light device (300) through the communication module unit (330) to emit light in a flashing manner by changing to another color when a pedestrian is detected in the crosswalk area.

[0056] Meanwhile, the communication module (330) may be responsible for the wireless communication environment of the shooting device (300) and the underground light device (400), including a Bluetooth mesh communication module. Here, in a Bluetooth mesh communication environment, a single master device can control multiple slave devices. By setting the shooting device (300) as the master and the underground light device (400) as the slave, the shooting device (300) can control the underground light device (400).

[0057] The underground lighting device (400) is installed underground at the leading edge of the crosswalk and operates using power supplied from the energy storage device (200), and can emit light when an underground lighting control signal is transmitted. For example, it can emit light in various colors such as white, red, green, and yellow.

[0058] Although the underground lighting device (400) is described as a single device, it should be understood that it is installed as a device having multiple underground lights, and the underground lighting device (400), which is a slave device, can operate (e.g., turn off, turn on, flash, etc.) according to the control of the shooting device (300), which is a master device, including a Bluetooth mesh communication module.

[0059] In addition, the underground lighting device (400) can be installed in various forms, such as having multiple circular underground lights arranged at each end of the crosswalk based on the direction of vehicle travel as shown in FIG. 5, or having multiple rectangular underground lights arranged as shown in FIG. 6, and the underground lights can be turned off or turned on according to a preset time range including daytime and evening time, depending on an operation control signal transmitted from the camera device (300).

[0060] Additionally, the underground light device (400) may turn on the underground light in an emergency according to an emergency lighting control signal transmitted from the camera device (300). The underground light may turn on in an emergency when the current illuminance value is relatively smaller than the preset reference illuminance value while the light is turned off or on according to a preset time range (e.g., on a rainy day, a snowy day, a cloudy day, etc.).

[0061] In addition, the underground light device (400) can be illuminated in white according to an operation control signal transmitted from the camera device (300) to emit light in one color at a time when it is illuminated according to a preset time range, and can be illuminated in a way that flashes red according to an underground light emission control signal transmitted from the camera device (300) to change to a different color and flash when a pedestrian is detected in the crosswalk area.

[0062] These color changes and flashing patterns can be set in various ways according to the user's needs.

[0063] Accordingly, one embodiment of the present invention supplies power generated through a solar power generation device to a camera, photographs a crosswalk area to determine whether a pedestrian is crossing, selectively transmits an underground light illumination control signal according to the determination result, and when the underground light illumination control signal is transmitted, the underground light device emits light, thereby detecting a pedestrian at the crosswalk and emitting the underground light, so that accidents at the crosswalk can be prevented in advance.

[0064] In addition, one embodiment of the present invention operates by supplying power from an energy storage device to a camera and an underground light device, and by transmitting an underground light illumination control signal from the camera to the underground light device according to a Bluetooth mesh communication method, the illumination of the underground light can be effectively controlled depending on whether a pedestrian is detected in the crosswalk area.

[0065] FIG. 7 is a flowchart illustrating the underground light notification process in an artificial intelligence-based pedestrian safety light according to one embodiment.

[0066] Referring to FIG. 7, power can be generated through a solar power generation device (110) comprising at least one solar panel (110) provided on the upper part of a support post installed on the side of a crosswalk (step 710).

[0067] In this step 710, the photovoltaic power generation device (110) may be provided with a grid output unit (120) that outputs power generated through the photovoltaic panel (110) to the grid line, and may perform a maximum power point tracking (MPPT) function by including at least one inverter (122) provided in the grid output unit (122).

[0068] Here, at least one inverter (122) has an MPPT function to obtain maximum power generation using a solar panel (110), and can adjust voltage and current output conditions to a value capable of producing maximum output.

[0069] Accordingly, the inverter (122) may stop operating when the output power value of the solar panel (110) is relatively lower than the maximum output point, according to MPPT control that enables operation when the maximum output point is higher.

[0070] For example, during times when the intensity of sunlight is weak, such as cloudy weather, just before sunset, or just after sunrise, the output power value of the solar panel (110) is lower than the maximum output point, so the operation of the corresponding inverter may be stopped, and the output power may be switched in series and parallel to the rear end of another solar panel of an adjacent (or nearby) solar power generation device through the switching unit (130), and through this, the output power of both sides may be added together and stored.

[0071] Additionally, the switching unit (130) provided in the photovoltaic power generation device (110) can perform series and parallel switching by connecting the photovoltaic panel (110) and the grid output unit (120) or by connecting the rear end of another photovoltaic panel of another photovoltaic power generation device, and can switch to output power to another station when the voltage value of the power is lower than a preset power value according to the control of the power generation control unit (140).

[0072] Next, the power generated through the solar power generation device (100) can be stored in the energy storage device (200) (step 720).

[0073] This energy storage device (200) can convert AC power output through the grid output unit (120) into DC power and store (charge) it in a battery (210), and can convert the DC power stored in the battery (210) into DC or AC power and supply it to a shooting device (300) and an underground lighting device (400), respectively. For example, a DC-DC converter can adjust the voltage level of the power and output it, and a DC-AC inverter can convert the power into AC power and output it.

[0074] And, power is supplied from the energy storage device (200) to the shooting device (300) equipped to photograph the crosswalk area on the support post to operate it, and the crosswalk area can be photographed (step 730).

[0075] In this step 730, the shooting device (300) can more effectively photograph pedestrians in the crosswalk area by operating camera functions such as pan, tilt, and zoom through the object recognition camera (310) under the control of the camera control unit (320).

[0076] Meanwhile, the camera control unit (320) of the shooting device (300) can detect whether a pedestrian is crossing in the captured image of the crosswalk area captured through the object recognition camera (310) (step 740).

[0077] In this step 740, the camera control unit (320) can identify and detect pedestrians using artificial intelligence in the image data transmitted through the object recognition camera (310), and can determine whether pedestrians are detected using artificial intelligence in the image data of the crosswalk area.

[0078] Here, artificial intelligence can utilize CNN models, and among them, algorithms such as the SSD algorithm, which offers fast object detection speed, and the Faster R-CCN ​​algorithm, which offers high object detection accuracy, can be used.

[0079] Next, when the camera control unit (320) detects a pedestrian crossing, it can transmit an underground light emission control signal from the shooting device through the communication module unit (330) (step 750).

[0080] In the step (750) of transmitting the underground light light control signal, the camera control unit (320) can transmit the underground light light control signal to the underground light device (400) through the communication module unit (330) according to the Bluetooth mesh communication method.

[0081] Of course, if no pedestrian is detected, normal camera control can be performed.

[0082] Next, power is supplied from the energy storage device (200) to the underground light device (400) installed in the ground at the edge of the crosswalk to operate it, and it can emit light when an underground light light control signal is transmitted (step 760).

[0083] Here, the underground lighting device (400) can turn off or on the underground lighting according to a preset time range including daytime and evening time based on an operation control signal transmitted from the shooting device (300). The preset time range can be set as daytime (e.g., 7:00 AM to 7:00 PM), evening time (e.g., 7:00 PM to 7:00 AM), etc., and since sunrise and sunset times differ depending on the four seasons such as spring, summer, autumn, and winter, the time range can be set by taking these factors into account.

[0084] Additionally, the underground light device (400) may turn on the underground light in an emergency according to an emergency lighting control signal transmitted from the camera device (300). The underground light may turn on in an emergency when the current illuminance value is relatively smaller than the preset reference illuminance value while the light is turned off or on according to a preset time range (e.g., on a rainy day, a snowy day, a cloudy day, etc.).

[0085] In addition, the underground light device (400) can be illuminated in white according to an operation control signal transmitted from the camera device (300) to emit light in one color at a time when it is illuminated according to a preset time range, and can be illuminated in a way that flashes red according to an underground light emission control signal transmitted from the camera device (300) to change to a different color and flash when a pedestrian is detected in the crosswalk area.

[0086] These color changes and flashing patterns can be set in various ways according to the user's needs.

[0087] Accordingly, another embodiment of the present invention supplies power generated through a solar power generation device to a camera, photographs a crosswalk area to determine whether a pedestrian is crossing, selectively transmits an underground light illumination control signal according to the determination result, and causes the underground light device to emit light when the underground light illumination control signal is transmitted, thereby detecting a pedestrian at the crosswalk and emitting the underground light, so that accidents at the crosswalk can be prevented in advance.

[0088] In addition, another embodiment of the present invention operates by supplying power from an energy storage device to a camera and an underground light device, and by transmitting an underground light illumination control signal from the camera to the underground light device according to a Bluetooth mesh communication method, the illumination of the underground light can be effectively controlled depending on whether a pedestrian is detected in the crosswalk area.

[0089] Although various embodiments of the present invention have been presented and described in the above description, the present invention is not necessarily limited thereto, and those skilled in the art will readily understand that various substitutions, modifications, and changes are possible within the scope of the technical concept of the present invention.
