[0009] In one embodiment, the endpoint streetlight terminal may transmit vehicle reduction information to the master streetlight terminal of the previous group to reduce the number of vehicles when the approach of the vehicle is confirmed.
[0010] In one embodiment, the slave streetlight terminal waits for the light quantity control signal from the master streetlight terminal of the group, and when the light quantity control signal is received, the output of the slave streetlight can be controlled according to the light quantity control signal.
[0011] According to another aspect of the present invention, a control method of the above-described smart streetlight group control system is provided, comprising: a first step in which a master streetlight terminal checks whether a vehicle is approaching and collectively controls the output of a plurality of streetlights within the group according to the approach of the vehicle; a second step in which a slave streetlight terminal controls the output of the corresponding streetlight according to the collective control of the master streetlight terminal; and a third step in which an endpoint streetlight terminal checks whether a vehicle is approaching and, according to the approach of the vehicle, transmits vehicle approach information to a master streetlight terminal of an adjacent group.

[0027] Hereinafter, some embodiments of the present disclosure will be described in detail with reference to exemplary drawings. When adding reference numerals to components in each drawing, identical components may have the same numerals as much as possible even if they are shown in different drawings. In addition, when describing the present embodiments, if it is determined that a detailed description of a related known configuration or function may obscure the gist of the technical idea of the present invention, the detailed description may be omitted. When "includes," "has," "consists of," etc. are used in this specification, other parts may be added unless "only" is used. When a component is expressed in the singular, it may include a case in which the plural is included unless specifically stated otherwise.
[0028] Additionally, terms such as first, second, A, B, (a), (b), etc. may be used to describe components of the present disclosure. These terms are only intended to distinguish the components from other components, and the nature, order, sequence, or number of the components are not limited by the terms.
[0029] In a description of the positional relationship of components, when it is described that two or more components are "connected," "combined," or "connected," it should be understood that the two or more components may be directly "connected," "combined," or "connected," but that the two or more components may also be further "interposed" with another component to be "connected," "combined," or "connected."

[0031] Meanwhile, when numerical values or corresponding information (e.g., levels, etc.) for components are mentioned, even without separate explicit description, the numerical values or corresponding information may be interpreted as including an error range that may occur due to various factors (e.g., process factors, internal or external impact, noise, etc.).
[0032] FIG. 1 is a configuration diagram of a smart streetlight group control system according to an embodiment of the present invention, and FIG. 2 is a schematic diagram for explaining the operation of a smart streetlight group control system according to an embodiment of the present invention.
[0033] Referring to FIGS. 1 and 2, a smart streetlight group control system (100) according to one embodiment of the present invention may include a master streetlight terminal (110), a slave streetlight terminal (120), and an endpoint streetlight terminal (130).
[0034] The smart streetlight group control system (100) divides a plurality of streetlights installed on a road into a plurality of groups (G1 to Gn) and controls the streetlights in groups according to the approach of a vehicle. The system can control only the streetlights in groups where a vehicle is present to output high illuminance, and the streetlights in groups where no vehicle is present to output low illuminance. Here, the groups (G1 to Gn) can be defined according to the direction of travel of the vehicle. That is, the vehicle first approaches the first group (G1) and sequentially proceeds to the last group (Gn). At this time, each group can be equipped with one master streetlight terminal (110) and a plurality of slave streetlight terminals (120).
[0035] Here, the master streetlight terminal (110) and slave streetlight terminal (120) of each group can communicate with the control server (11) via a repeater (12). For example, the master streetlight terminal (110), slave streetlight terminal (120), and repeater (12) can perform LoRa communication. The repeater (12) and the control server (11) can communicate via a public communication network such as LTE or 5G.
[0036] At this time, the control server (11) can monitor and manage the status of the master streetlight terminal (110) and slave streetlight terminal (120) of each group through the repeater (12). For example, the control server (11) can set the light intensity of the streetlight when a vehicle approaches. In addition, the control server (11) can manage the maintenance of the master streetlight terminal (110) and slave streetlight terminal (120).
[0037] At this time, if no vehicle is approaching, the streetlight can output at the first level of illumination. For example, the first level of illumination represents 20% of the light output. Furthermore, if a vehicle is approaching, the streetlight can output at the second level of illumination. For example, the second level represents 100% of the light output.
[0038] Master streetlight terminals (110) are installed in groups to detect the approach of vehicles. For example, the master streetlight terminal (110) may be installed on a streetlight positioned first in the direction of vehicle travel within the group. Alternatively, the master streetlight terminal (110) may be installed on a streetlight positioned midway in the direction of vehicle travel within the group.
[0039] A master streetlight terminal (110) can collectively control the output of multiple streetlights within a given group based on the approach of a vehicle. Here, the multiple streetlights may include not only streetlights equipped with slave streetlight terminals but also streetlights equipped with a master streetlight terminal. In other words, the multiple streetlights refer to all streetlights within the given group.
[0040] A slave streetlight terminal (120) may be installed on each of a plurality of streetlights within a group. Here, the plurality of streetlights refers to all streetlights within the group except for the streetlights on which the master streetlight terminal (110) is installed. In this case, the slave streetlight terminal (120) may control the output of the corresponding streetlight according to the collective control of the master streetlight terminal (110).
[0041] The endpoint streetlight terminal (130) may be installed at the last endpoint streetlight in the direction of travel of the vehicle. In other words, the endpoint streetlight refers to the last streetlight that the vehicle passes through. At this time, the endpoint streetlight terminal (130) may check whether a vehicle is approaching and, upon the vehicle's approach, transmit vehicle approach information to the master streetlight terminal (110-n) of the adjacent group (Gn). Here, the adjacent group may be the last group (Gn).
[0042] In this way, the smart streetlight group control system (100) according to one embodiment of the present invention has the effect of increasing energy efficiency by detecting vehicle traffic and controlling lighting output for a specific range according to the location of the vehicle.
[0043] FIG. 3 is a block diagram of a master streetlight terminal of a smart streetlight group control system according to an embodiment of the present invention.
[0044] Referring to FIG. 3, the master streetlight terminal (110) may include a camera module (111), a communication module (112), an object identification module (113), a light output signal generation module (114), a light quantity control module (115), and a vehicle count module (116). Here, the object identification module (113), the light output signal generation module (114), the light quantity control module (115), and the vehicle count module (116) may be implemented as a microprocessor.
[0045] A camera module (111) is installed in a master streetlight to capture images of approaching vehicles on the road. Here, the master streetlight refers to a streetlight in a group in which a master streetlight terminal (110) is installed. In other words, the camera module (111) can be installed in the direction in which vehicles enter the road.
[0046] The communication module (112) can communicate with a slave streetlight terminal (120) within the group. In addition, the communication module (112) can communicate with a master streetlight terminal (110) of another group. In addition, the communication module (112) can communicate with a repeater (12). Here, the communication module (112) can perform RoLa communication.
[0047] The object identification module (113) can analyze the image acquired through the camera module (112) equipped in the master streetlight to determine whether a vehicle is approaching. For example, the object identification module (113) can construct a virtual boundary box from the image acquired from the camera module (111), and determine that the vehicle is approaching when the vehicle moves from one side of the boundary box to the other side (see FIG. 6).
[0048] The lighting output signal generation module (114) can generate a lighting output signal to control multiple streetlights within the group to the first illuminance level if, as a result of the judgment of the object identification module (113), there is no vehicle in the corresponding section. Here, the lighting output signal can be a light quantity control signal. That is, if there is no vehicle approaching or present in the corresponding section, the lighting output signal generation module (114) can transmit a light quantity control signal of the first illuminance level to the slave streetlight terminal (120).
[0049] In addition, the lighting output signal generation module (114) can generate a lighting output signal to control multiple streetlights in the group to a second illuminance level if a vehicle is present in the corresponding section based on the judgment result of the object identification module (113). Here, the lighting output signal can be a light quantity control signal. That is, the lighting output signal generation module (114) can transmit a light quantity control signal of a second illuminance level to the slave streetlight terminal (120) if a vehicle approaches or is present in the corresponding section.
[0050] The light quantity control module (115) can control the output of a streetlight in which a master streetlight terminal (110) is installed. For example, the light quantity control module (115) can control the output of the streetlight according to the light quantity control signal of the lighting output signal generation module (114).
[0051] The vehicle count module (116) can count the number of vehicles entering a section corresponding to a given group based on the approach of a vehicle. For example, the vehicle count module (116) can increase the number of vehicles in the corresponding section upon confirming the approach of a vehicle. At this time, the vehicle count module (116) can transmit vehicle reduction information to the master streetlight terminal of the previous group to reduce the number of vehicles.
[0052] In addition, the vehicle count module (116) can reduce the number of vehicles within a given area when it receives vehicle reduction information from the master streetlight terminal of the next group. That is, when a vehicle enters the group, the vehicle count module (116) directly transmits vehicle reduction information to the group, receives vehicle reduction from the master streetlight terminal of the next group, and determines that the group has lost vehicles, thereby counting the number of vehicles within the group.
[0053] In this way, the smart streetlight group control system (100) according to one embodiment of the present invention can improve the efficiency and accuracy of dimming control by counting the inflow and outflow of vehicles for each section corresponding to a streetlight group.
[0054] FIG. 4 is a block diagram of a slave streetlight terminal of a smart streetlight group control system according to an embodiment of the present invention.
[0055] Referring to FIG. 4, the slave streetlight terminal (120) may include a communication module (122) and a light control module (125). Here, the communication module (122) has the same configuration as the communication module (112) of the master streetlight terminal (110), so a detailed description thereof is omitted here.
[0056] The light quantity control module (125) can wait for receiving a light quantity control signal from the master streetlight terminal (110) of the corresponding group. At this time, when the light quantity control signal is received, the light quantity control module (125) can control the output of the corresponding slave streetlight according to the light quantity control signal. Here, the slave streetlight means a streetlight on which a slave streetlight terminal (120) is installed.
[0057] FIG. 5 is a block diagram of an endpoint streetlight terminal of a smart streetlight group control system according to an embodiment of the present invention.
[0058] Referring to FIG. 5, the endpoint streetlight terminal (130) may include a camera module (131), a communication module (132), an object identification module (133), a light amount control module (135), and a vehicle count module (136).
[0059] Here, the camera module (131), communication module (132), and object identification module (133) have the same configuration as the camera module (111), communication module (112), and object identification module (113) of the master streetlight terminal (110), so a detailed description thereof is omitted here.
[0060] When the vehicle count module (136) confirms the approach of a vehicle, it can transmit vehicle reduction information to the master streetlight terminal (110-n) of the previous group (Gn) to reduce the number of vehicles. In other words, the vehicle count module (116) can count the number of vehicles exiting the streetlight installation section.
[0061] The light control module (135) can control the endpoint streetlight to output at a constant illuminance. That is, the light control module (135) can control the endpoint streetlight to output at a constant illuminance without changing its output. For example, the light control module (135) can control the endpoint streetlight to output at a second illuminance.
[0062] FIG. 6 is a drawing for explaining an example of a vehicle entry determination operation of a master streetlight terminal of a smart streetlight group control system according to an embodiment of the present invention, and FIG. 7 is a drawing for explaining another example of a vehicle entry determination operation of a master streetlight terminal of a smart streetlight group control system according to an embodiment of the present invention.
[0063] Referring to FIG. 6, the object identification module (113) constructs a virtual boundary box from the image acquired by the camera module (111), and when a vehicle moves from one side of the boundary box to the other, it can be determined that the vehicle is approaching. Here, the object identification module (113) can set a boundary box horizontally in the image. In this case, the vehicle moves from top to bottom in the image.
[0064] Referring to FIG. 7, the object identification module (113) may set a vertical boundary box in the image. In this case, the vehicle moves from left to right in the image.
[0065] At this time, the boundary box may be a location corresponding to the location of the first streetlight in the group. That is, the object identification module (113) can determine that a vehicle has entered the group when the vehicle passes through the boundary box.
[0066] Hereinafter, the smart streetlight group control method of the present invention will be described with reference to FIGS. 8 to 10.
[0067] Here, the smart streetlight group control method of the present invention includes a first step (200A) in which a master streetlight terminal (110) checks whether a vehicle is approaching and collectively controls the output of multiple streetlights within the group according to the approach of the vehicle;
[0068] A second step (300) in which a slave streetlight terminal (120) controls the output of the corresponding streetlight according to the collective control of the master streetlight terminal (110); and
[0069] It includes a third step (200A) in which the endpoint streetlight terminal (130) checks whether a vehicle is approaching and transmits vehicle approach information (vehicle reduction information) to the master streetlight terminal (110-n) of the adjacent group according to the vehicle approach.
[0070] FIG. 8 is a flowchart of a method for controlling an endpoint streetlight terminal of a smart streetlight group control method according to an embodiment of the present invention.
[0071] Referring to FIG. 8, the control method (200A) of an endpoint streetlight terminal includes a step of confirming the terminal (S201 to S202), a step of setting an output (S203), and a step of identifying and counting an object (S204 and S205).
[0072] To explain in more detail, as illustrated in FIG. 8, first, the streetlight terminal (110, 130) extracts the group ID (GID) built into the processor and sets the number of vehicles (cnt) to 0 (step S201).
[0073] Next, the streetlight terminal determines whether it is an endpoint streetlight (step S202), and if it determines that it is not an endpoint streetlight, it proceeds to step S211. Here, steps S201 and S202 are terminal identification processes and can be performed equally in both the master streetlight terminal (110) and the endpoint streetlight terminal (130).
[0074] If it is determined as an endpoint streetlight as a result of the judgment in step S202, the endpoint streetlight terminal (130) controls the output to the second level (Dim=100%) (step S203).
[0075] Next, the endpoint streetlight terminal (130) identifies the object (step S204) and if the object is not identified, the process continues until the object is identified. Here,
[0076] If the determination result of step S204 identifies an object, the endpoint streetlight terminal (130) transmits vehicle reduction information to the master streetlight terminal (110) of the previous group (PREGID) to reduce the number of vehicles (step S205). Thereafter, the endpoint streetlight terminal (130) returns to step S204 and can continue to identify objects. In other words, the endpoint streetlight terminal (130) can identify passing vehicles.
[0077] Figure 9 is an operation flowchart of a master streetlight terminal of a smart streetlight group control method according to an embodiment of the present invention.
[0078] Referring to FIG. 9, the control method (200B) of the master streetlight terminal includes a waiting step (S211), a step of identifying an object (S212), a step of increasing output (S213), and a step of counting the number of vehicles (S214 to S218).
[0079] To explain in more detail, as illustrated in FIG. 9, first, the master streetlight terminal (110) controls the streetlights of the corresponding group to the same illuminance (step S211). At this time, the master streetlight terminal (110) may be set to the first illuminance (Dim=20%).
[0080] Next, the master streetlight terminal (110) analyzes the image acquired through the camera module to check whether a vehicle is approaching and identifies an object (step S212). If the object is not identified, the process proceeds to step S216.
[0081] As a result of the judgment in step S212, if an object is identified by an approaching vehicle, the master streetlight terminal (110) transmits a light quantity control signal (Dim=100%) to the slave streetlight terminal (120) to control multiple streetlights in the group to the second level (step S213).
[0082] Next, the master streetlight terminal (110) counts the number of vehicles entering the section corresponding to the group depending on whether the vehicle is approaching. At this time, the master streetlight terminal (110) increases the number of vehicles (cnt) by 1 (step S214).
[0083] Next, the master streetlight terminal (110) transmits vehicle reduction information (-1) to the master streetlight terminal of the previous group to decrease the number of vehicles (step S215). That is, the master streetlight terminal (110) can transmit a value of -1 as the number of vehicles (cnt) to count the number of vehicles that have left the previous group as vehicles move to the corresponding group.
[0084] Next, the master streetlight terminal (110) determines whether to receive vehicle reduction information from the master streetlight terminal of the next group (step S216), and if not, proceeds to step S218. Here, the received vehicle reduction information may be a number of vehicles (cnt) with a value of -1 to count the number of vehicles leaving the group as vehicles enter the next group.
[0085] As a result of the judgment in step S216, if vehicle reduction information is received from the master streetlight terminal of the next group, the master streetlight terminal (110) reduces the number of vehicles (cnt) in the corresponding area by 1 (step S217).
[0086] Next, the master streetlight terminal (110) determines whether the number of vehicles (cnt) is 0 (step S218), and if not 0, proceeds to step S212 and repeatedly performs the processes of steps S212 to S217. That is, if there are vehicles within the section, the streetlights within the group can be controlled to the second illuminance (DiM=100%) while continuously counting the inflow and outflow of vehicles.
[0087] If the number of vehicles (cnt) is 0 as a result of the judgment in step S218, the process returns to step S211, and the master streetlight terminal (110) controls the corresponding group as the first streetlight. That is, since there are no vehicles in the corresponding section, the master streetlight terminal (110) can control multiple streetlights of the corresponding group as the first streetlight in the original standby state.
[0088] Fig. 10 is an operation flowchart of a slave streetlight terminal of a smart streetlight group control method according to an embodiment of the present invention.
[0089] Referring to FIG. 10, the control method (300) of a slave streetlight terminal includes a step of identifying the terminal (S301), a step of waiting for reception (S302), and a step of adjusting the output according to the master (steps S303 and S304).
[0090] To explain in more detail, as illustrated in FIG. 10, first, the slave streetlight terminal (120) extracts the group ID (GID) built into the processor (step S301).
[0091] Next, the slave streetlight terminal (120) waits to receive a signal from the master streetlight terminal (110) of the same group (step S302).
[0092] Thereafter, when the slave streetlight terminal (120) receives a light quantity control signal (Dim) from the master streetlight terminal (110) (step S303), it controls the output of the corresponding streetlight according to the light quantity control signal (Dim) (step S304). At this time, the slave streetlight terminal (120) can control the output of the corresponding streetlight according to the first illumination. In addition, the slave streetlight terminal (120) can control the output of the corresponding streetlight according to the second illumination.
[0093] The smart streetlight group control method according to the embodiments of the present invention described above can be implemented as an application (computer program) stored in a storage medium of a computer.
[0094] Here, the computer may include a smart streetlight group control system.
[0095] The computer's operating system may be an operating system such as Windows or Macintosh, which is installed on general PCs such as desktops and laptops, or a mobile-only operating system such as iOS or Android, which is installed on mobile devices such as smartphones and tablet PCs.
[0096] The smart streetlight group control method according to the embodiments of the present invention described above may be implemented as an application (i.e., a computer program) installed by default on a computer or installed by a user, and may be stored (recorded) on a computer-readable storage medium.
[0097] In this way, in order for a computer to read a program recorded on a storage medium and execute the smart streetlight group control method according to the embodiments implemented as a program, the application (application program) described above may include code (Code) coded in a computer language such as C, C++, JAVA, or machine language that can be read by a computer's processor (CPU).
