Description

Technology Field

[0001] The present invention relates to a real-time notification system using a high-precision positioning device and a method of operation for the same. More specifically, it relates to a real-time notification system and a method of operation for the same that provides lane classification information in real time to indicate (or identify) a work lane in a road emergency situation, such as a highway traffic accident or road closure operation, based on a device to which high-precision positioning technology is applied. Background Technology

[0002] Generally, when performing standalone positioning based on a Global Navigation Satellite System (GNSS) (i.e., using only one GNSS receiver), there are aspects where it is difficult to accurately obtain the location of the corresponding terminal due to satellite errors, atmospheric errors, or ground errors.

[0003] For reference, satellite error is associated with at least one of satellite orbit, satellite time, and satellite data, atmospheric error is associated with at least one of ionospheric and tropospheric delay, and ground error may be associated with at least one of signal distortion, multipath, and receiver.

[0004] Difference GNSS (hereinafter 'DGNSS') technology transmits correction information (Radio Technical Commission for Maritime Services, hereinafter 'RTCM') generated from a reference station installed at accurate absolute coordinates to a GNSS receiver (i.e., a mobile station, hereinafter 'Rover') located within an effective radius (e.g., within 10 to 20 km in RTK positioning) to compensate for factors causing errors in GNSS accuracy, and the mobile station (Rover) that receives this can correct the error.

[0005] DGNSS technology can be classified into Differential GPS (hereinafter 'DGPS') technology and Real Time Kinematic (hereinafter 'RTK') technology.

[0006] Specifically, if the signal used for positioning corresponds to a digital code signal (e.g., C / A code), it is DGPS technology, and if the signal used for positioning corresponds to a carrier signal with a constant period, it may be RTK technology. However, the error correction principles of DGPS and RTK technologies are identical.

[0007] Refer to Korean Registered Patent No. 10-2320523, which mentions a "geodetic surveying system capable of acquiring high-precision coordinates in real time through RTK control surveying of GPS" as a prior proposal. The problem to be solved

[0008] The purpose of this specification is to provide a real-time notification system using a high-precision positioning device and a method of operation for the same.

[0009] The technical problems to be solved by this specification are not limited to those mentioned above, and other technical problems not mentioned will be clearly understood by those skilled in the art to which this specification belongs from the description below. means of solving the problem

[0010] A method of operation of a real-time notification system using a high-precision positioning device according to the present embodiment includes: receiving RTK coordinate information associated with RTK positioning from a high-precision positioning device; generating map data associated with an open source geographic information system (QGIS) based on pre-stored precision road map information; setting a search area of ​​a predetermined radius based on RTK coordinate information on the map data; determining whether a plurality of lanes are included within the search area; determining a work lane based on the determination; generating lane classification information indicating the work lane; and transmitting alarm information including lane classification information to an administrator terminal.

[0011] According to the present embodiment, when the plurality of lanes are included within the search area, the lane closest to the RTK coordinate information among the plurality of lanes is determined to be the work lane.

[0012] According to the present embodiment, when multiple lanes are not included within the search area, a single lane is determined to be the work lane.

[0013] According to the present embodiment, map data is generated by applying a pre-stored lane-specific coordinate transformation function to precise road map information, and the precise road map information is implemented to include at least one of information such as lanes, lane centerlines, regulatory lines, road boundaries, road centerlines, traffic signs, and road surface markings. Effects of the invention

[0014] According to the present embodiment, a real-time notification system and a method of operation for the same may be provided, which provide real-time lane classification information capable of identifying road incidents, such as highway traffic accidents or blocking operations, on a lane-by-lane basis, based on a device equipped with high-precision positioning technology.

[0016] The aforementioned characteristics and the detailed description below are all exemplary matters to aid in the explanation and understanding of this specification. That is, this specification is not limited to such embodiments and may be embodied in other forms. The following embodiments are merely examples to fully disclose this specification and are intended to convey this specification to those skilled in the art to which this specification belongs. Accordingly, if there are multiple methods for implementing the components of this specification, it is necessary to make clear that the specification can be implemented by any of these specific methods or any method identical thereto.

[0017] Where in this specification it is mentioned that a configuration includes specific elements, or that a process includes specific steps, it implies that other elements or steps may be additionally included. That is, the terms used in this specification are intended only to describe specific embodiments and are not intended to limit the concept of this specification. Furthermore, the examples described to aid in understanding the invention also include complementary embodiments.

[0018] The terms used in this specification have the meanings generally understood by those skilled in the art to which this specification pertains. Commonly used terms should be interpreted in a consistent sense according to the context of this specification. Furthermore, terms used in this specification should not be interpreted in an overly ideal or formal sense unless their meaning is clearly defined. Embodiments of this specification are described below with reference to the attached drawings.

[0019] FIG. 1 is a diagram illustrating position positioning based on RTK technology according to the present embodiment.

[0020] Referring to FIG. 1, the reference station (10) of FIG. 1 is installed at absolute coordinates (x1, y1, z1) and can transmit correction information (RTCM) to a mobile station (110) located at specific coordinates (x1', y1', z1') within the effective radius.

[0021] For example, the correction information (RTCM) may be implemented to include correction data (dx, dy, dz) for correcting errors with GNSS satellites due to the difference in distance between the reference station (10) and the mobile station (110).

[0022] It will be understood that, according to one embodiment of the present specification, RTK technology using a carrier signal for positioning of a mobile station (110) may be applied.

[0023] Meanwhile, according to the present embodiment, the position of the mobile station (110) has an error of only 1 to 3 cm due to the application of RTK technology, so it will be understood that a high-precision positioning device capable of positioning with superior accuracy compared to conventional GNSS-based positioning can be provided.

[0024] For example, the frequency of the carrier signal used for positioning of the mobile station (110) may be 1575.42 MHz. In this case, the wavelength of the carrier signal may be about 19.1 cm.

[0025] Meanwhile, in FIG. 1, the reference station (10) is depicted as one, but it will be understood that the present specification is not limited thereto. In other words, the mobile station (110) may be implemented to receive correction information (RTCM) from one or more reference stations.

[0026] FIG. 2 is a block diagram showing a real-time notification system using a high-precision positioning device according to the present embodiment.

[0027] Referring to FIGS. 1 and 2, a real-time notification system (200) using a high-precision positioning device may include a high-precision positioning device (210) and a server device (220).

[0028] In this case, the server device (220) can communicate with the high-precision positioning device (210) by linking with one or more base stations (2).

[0029] The high-precision positioning device (210) of FIG. 2 may include an RTK GPS module (211), a communication module (213), a control module (215), and a power module (217).

[0030] For example, the RTK GPS module (211) may be implemented to generate RTK coordinate information based on a correction signal (RTCM) received from one or more reference stations (20).

[0031] For example, the communication module (213) can be implemented based on low-power long-range communication technology (LPWA), such as Cat.M1 broadband communication.

[0032] That is, the communication module (213) can be implemented to transmit RTK coordinate information generated from the high-precision positioning device (210) to the communication module (223) of the server device (220) through one or more base stations (2).

[0033] For example, the control module (215) may be implemented to control the overall positioning operation of the high-precision positioning device (210). As an example, the control module (215) may be implemented based on a Micro Controller Unit (MCU).

[0034] For example, the power module (217) can be implemented to supply power to the high-precision positioning device (210) and can be implemented as a wireless battery rechargeable or wired.

[0035] Meanwhile, the server device (220) of FIG. 2 may include a coordinate conversion module (221), a communication module (223), a database (225), and a lane classification module (227).

[0036] For example, the coordinate transformation module (221) can be implemented to generate map data associated with an open source geographic information system (QGIS) based on precision road map information stored in advance in a database (225).

[0037] For example, the coordinate transformation module (221) can be implemented to immediately generate map data based on the WGS 84 coordinate system based on precision road map information based on the UTM52N coordinate system stored in advance in the database (225).

[0038] As another example, the coordinate transformation module (221) can be implemented to generate map data based on the WGS 84 coordinate system by applying a pre-stored lane-specific coordinate transformation function to precision road map information based on the UTM-K coordinate system that is pre-stored in the database (225).

[0039] For example, the communication module (223) can be implemented based on low-power long-range communication technology (LPWA), such as Cat.M1 broadband communication.

[0040] That is, the communication module (223) can be implemented to receive RTK coordinate information generated by the high-precision positioning device (210) from the communication module (213) of the high-precision positioning device (210) through one or more base stations (2).

[0041] For example, the database (225) may be implemented to store road information (i.e., precise road map information) associated with areas where work plans for roads or lanes are made from a national management database (not shown) such as the National Geographic Research Institute.

[0042] Here, the precision road map information may be information based on the UTM52N coordinate system or the UTM-K coordinate system.

[0043] As another example, the database (225) may be implemented to store only precision road map information corresponding to a certain range by referencing RTK coordinate information.

[0044] In this case, the precision road map information may include at least one of the following: lanes, lane centerlines, regulatory lines, road boundaries, road centerlines, traffic signs, and road surface markings.

[0045] For example, the lane classification module (227) can be implemented to set a search area of ​​a predetermined radius (e.g., R in FIG. 5) based on RTK coordinate information. In this case, a Sweep Line algorithm can be applied to the lane classification module (227).

[0046] In addition, it can be implemented to calculate the distance between the centerlines of multiple lanes based on a reference point (e.g., O in Fig. 5) determined according to RTK coordinate information.

[0047] Additionally, the lane classification module (227) may be implemented to determine the lane closest to a reference point (e.g., O in FIG. 5) determined according to RTK coordinate information. In this case, a Divide and conquer algorithm may be applied to the lane classification module (227).

[0048] FIG. 3 is a diagram illustrating the operation process of a real-time notification system using a high-precision positioning device according to the present embodiment.

[0049] Referring to FIGS. 1 to 3, the high-precision positioning device (310) of FIG. 3 corresponds to the high-precision positioning device (210) of FIG. 2, and the server device (320) of FIG. 3 corresponds to the server device (220) of FIG. 2.

[0050] For example, the high-precision positioning device (310) can be connected to a server device (320) through one or more base stations (3) based on low-power long-range communication technology (LPWA).

[0051] Additionally, the high-precision positioning device (310) can be implemented to perform positioning of the mobile station (M') based on a correction signal transmitted from one or more reference stations (30) using a carrier signal.

[0052] The administrator terminal (330) of FIG. 3 may be implemented to receive alarm information including lane separation information for identifying a work lane from a server device (320). For example, it will be understood that a Human Machine Interface (HMI) for an administrator may be applied to the administrator terminal (330).

[0053] FIG. 4 is a diagram illustrating the operation method of a real-time notification system using a high-precision positioning device according to the present embodiment.

[0054] Referring to FIGS. 1 to 4, a server device (e.g., 220 in FIG. 2) of a real-time notification system (e.g., 200 in FIG. 2) using a high-precision positioning device according to the present embodiment may be implemented to perform steps S410 to S470 in conjunction with a high-precision positioning device (e.g., 210 in FIG. 2).

[0055] In step S410, a real-time notification system (e.g., 200 in FIG. 2) using a high-precision positioning device according to the present embodiment can receive RTK coordinate information associated with RTK positioning from a high-precision positioning device (e.g., 210 in FIG. 2).

[0056] For example, the RTK GPS module (e.g., 211 in FIG. 2) of the high-precision positioning device (e.g., 210 in FIG. 2) according to the present embodiment may be implemented to generate RTK coordinate information based on correction signals received from one or more reference stations (e.g., 20 in FIG. 2).

[0057] In addition, RTK coordinate information can be received by the communication module (e.g., 211 in FIG. 2) of a server device (e.g., 220 in FIG. 2) through the communication module (e.g., 223 in FIG. 2) of a high-precision positioning device (e.g., 210 in FIG. 2).

[0058] In step S420, a real-time notification system (e.g., 200 in FIG. 2) using a high-precision positioning device according to the present embodiment can generate map data associated with an open source geographic information system (QGIS) based on pre-stored high-precision road map information.

[0059] For example, a coordinate transformation module (e.g., 221 in FIG. 2) of a server device (e.g., 220 in FIG. 2) according to the present embodiment may be implemented to generate map data associated with an open source geographic information system (QGIS) based on pre-stored high-precision road map information.

[0060] For example, a coordinate transformation module (e.g., 221 in FIG. 2) can be implemented to immediately generate map data based on the WGS 84 coordinate system based on high-precision road map information based on the UTM52N coordinate system stored in a database (e.g., 225 in FIG. 2).

[0061] As another example, a coordinate transformation module (e.g., 221 in FIG. 2) can be implemented to generate map data based on the WGS 84 coordinate system by applying a pre-stored lane-specific coordinate transformation function to high-precision road map information based on the UTM-K coordinate system that is pre-stored in a database (e.g., 225 in FIG. 2).

[0062] For example, high-precision road map information can be obtained in advance from a national management database (not shown), such as the National Geographic Information Institute. In this case, the high-precision road map information may include at least one of lanes, lane centerlines, regulatory lines, road boundaries, road centerlines, traffic signs, and road surface markings.

[0063] For example, precise road map information can be implemented to retrieve road information associated with the area from a national management database (not shown) by referring to a work plan for a road or lane, and to store it in advance in a database (e.g., 225 in FIG. 2) of a server device (e.g., 220 in FIG. 2).

[0064] As another example, precise road map information can be implemented to retrieve road information associated with RTK coordinate information from a national management database (not shown) by referencing RTK coordinate information, and to store it in advance in a database (e.g., 225 in FIG. 2) of a server device (e.g., 220 in FIG. 2).

[0065] In step S430, a real-time notification system (e.g., 200 in FIG. 2) using a high-precision positioning device according to the present embodiment can set a search area of ​​a predetermined radius (e.g., R in FIG. 5) based on RTK coordinate information on map data as described later in FIG. 5.

[0066] For example, a lane classification module (e.g., 227 in FIG. 2) of a server device (e.g., 220 in FIG. 2) according to the present embodiment may be implemented to set a search area (e.g., R in FIG. 5) of a predetermined radius based on RTK coordinate information.

[0067] In this case, it will be understood that a Sweep Line algorithm may be applied to the lane separation module (e.g., 227 in FIG. 2) to set a search area of ​​a predetermined radius (e.g., R in FIG. 5).

[0068] In step S440, a real-time notification system (e.g., 200 in FIG. 2) using a high-precision positioning device according to the present embodiment can determine whether a plurality of lanes (e.g., L1, L2 in FIG. 5) are included within a preset search area (e.g., R in FIG. 5).

[0069] For example, a lane classification module (e.g., 227 in FIG. 2) of a server device (e.g., 220 in FIG. 2) according to the present embodiment may be implemented to determine whether a preset search area (e.g., R in FIG. 5) overlaps (or includes) a plurality of lanes (e.g., L1, L2 in FIG. 5) corresponding to map data.

[0070] If it is determined that a pre-set search area (e.g., R in FIG. 5) and multiple lanes (e.g., L1, L2 in FIG. 5) overlap (or are included), the procedure proceeds to step S450. Additionally, if it is determined that only a single lane overlaps (or is included) with a pre-set search area (e.g., R in FIG. 5), the procedure proceeds to step S460.

[0071] In step S450, a real-time notification system (e.g., 200 in FIG. 2) using a high-precision positioning device according to the present embodiment can determine the lane closest to the search area (e.g., R in FIG. 5) that overlaps (or includes) with the search area (e.g., R in FIG. 5) based on RTK coordinate information as the work lane.

[0072] For example, a lane separation module (e.g., 227 in FIG. 2) of a server device (e.g., 220 in FIG. 2) according to the present embodiment may be implemented to calculate the distance between the centerline of a first lane (e.g., L1 in FIG. 5) (e.g., L1_CT in FIG. 5) and the centerline of a second lane (e.g., L2 in FIG. 5) (e.g., L2_CT in FIG. 5) based on a reference point (e.g., O in FIG. 5) determined according to RTK coordinate information.

[0073] Next, the lane classification module (e.g., 227 in FIG. 2) of the server device (e.g., 220 in FIG. 2) according to the present embodiment can be implemented to determine the lane (i.e., L1) closest to a reference point (e.g., O in FIG. 5) determined according to RTK coordinate information as the work lane.

[0074] For example, it will be understood that a Divide and Conquer algorithm can be applied to determine the lane closest to a reference point (e.g., O in Fig. 5) determined by RTK coordinate information.

[0075] In step S460, a real-time notification system (e.g., 200 in FIG. 2) using a high-precision positioning device according to the present embodiment can determine a single lane that overlaps (or includes) a pre-set search area (e.g., R in FIG. 5) based on RTK coordinate information as a work lane.

[0076] For example, a lane classification module (e.g., 227 in FIG. 2) of a server device (e.g., 220 in FIG. 2) according to the present embodiment may be implemented to determine a single lane as a work lane based on a reference point determined according to RTK coordinate information.

[0077] In step S470, a real-time notification system (e.g., 200 in FIG. 2) using a high-precision positioning device according to the present embodiment can generate lane classification information indicating a work lane.

[0078] For example, a lane separation module (e.g., 227 in FIG. 2) of a server device (e.g., 220 in FIG. 2) according to the present embodiment may be implemented to generate lane separation information that includes not only information that can identify a work lane based on map data, but also other information associated with the work lane.

[0079] In addition, a real-time notification system using a high-precision positioning device according to the present embodiment (e.g., 200 in FIG. 2) can transmit alarm information including lane classification information to an administrator terminal.

[0080] For example, for example, a communication module (e.g., 223 in FIG. 2) of a server device (e.g., 220 in FIG. 2) according to the present embodiment may be implemented to transmit alarm information including lane classification information to an administrator terminal (e.g., 330 in FIG. 3).

[0081] According to the present embodiment, a real-time notification system and a method of operation for the same may be provided, which provide real-time lane classification information capable of identifying road incidents, such as highway traffic accidents or blocking operations, on a lane-by-lane basis, based on a device equipped with high-precision positioning technology.

[0082] Meanwhile, although not illustrated in FIG. 4, a real-time notification system using a high-precision positioning device according to the present embodiment (e.g., 200 in FIG. 2) can be implemented to further determine whether a work lane indicated by lane classification information corresponds to a work area predetermined by a manager.

[0083] Furthermore, if the work lane indicated by the lane classification information matches a work zone predetermined by the manager, the information regarding the work lane may be implemented to be transmitted to the drivers' terminals via the server of a private navigation company.

[0084] FIG. 5 is a diagram illustrating the process of setting a search area for generating lane classification information according to the present embodiment.

[0085] Referring to FIGS. 1 to 5, a high-precision positioning device (e.g., 210 of FIG. 2) according to the present embodiment can be installed (or attached) to a work signal vehicle (500) of FIG. 2.

[0086] That is, a work signal vehicle (500) equipped with (or attached to) a high-precision positioning device (e.g., 210 in FIG. 2) may be implemented to be connected to a work vehicle (5') and to move together with the work vehicle (5') or to stop in front of the work site with the work vehicle (5').

[0087] For example, a lane classification module (e.g., 227 in FIG. 2) of a server device (e.g., 220 in FIG. 2) may be implemented to determine a reference point (O) associated with the location where the work signal vehicle (500) is stopped, based on RTK coordinate information generated by a high-precision positioning device (e.g., 210 in FIG. 2) installed (or attached) to the work signal vehicle (500).

[0088] In other words, the center point (O) of a search area (R) with a predetermined radius can correspond to a reference point determined according to RTK coordinate information.

[0089] Additionally, a lane separation module (e.g., 227 in FIG. 2) of a server device (e.g., 220 in FIG. 2) can be implemented to set a search area (R) having a predetermined radius (D) centered on a reference point (O).

[0090] For example, the search area (R) of a predetermined radius in FIG. 5 is set as a circle, and the radius (D) of the search area (R) can be set to a predetermined size (e.g., 3.6 m), but it will be understood that the present embodiment is not limited to FIG. 5.

[0091] In other words, the shape of the search area (R) with a predetermined radius can be implemented as a polygon such as a square, and the radius (D) can also be adjusted differently depending on the working environment.

[0092] FIG. 6 is a drawing for explaining the physical structure of a high-precision positioning device according to the present embodiment.

[0093] Referring to FIGS. 1 to 6, the high-precision positioning device (600) of FIG. 6 may correspond to the high-precision positioning device (200) of FIG. 2.

[0094] For example, the high-precision positioning device (600) may include a GPS antenna (610), a waterproof housing (620), a PCB (630), an RTK GPS / LPWAN module (635), an anti-shake sealing (640), a magnet for vehicle attachment (650), a waterproof sealing (660), a wired communication and charging terminal (670), and a lithium-ion battery (680).

[0095] For example, an RTK GPS / LPWAN module (635) may be mounted on a PCB (630). For example, the RTK GPS / LPWAN module (635) may be implemented as an integrated RTK GPS module and an LPWAN communication module or independently.

[0096] For example, it will be understood that the mobile station (e.g., 110 in FIG. 1) can be attached to a specific location on a vehicle (e.g., M' in FIG. 3) corresponding to the mobile station (e.g., 110 in FIG. 1) or attached to a specific location on a work signal vehicle (e.g., 500 in FIG. 3) corresponding to the mobile station (e.g., 110 in FIG. 1) via a vehicle attachment magnet (650).

[0097] FIG. 7 is a block diagram showing the physical configuration of a server device according to an embodiment of the present invention.

[0098] Referring to FIGS. 1 to 7, the server device (700) according to the present embodiment may correspond to the server device of FIG. 2 (e.g., 220 of FIG. 2).

[0099] For example, the server device (700) may include a bus (710), a display (720), a communication circuit (730), a database (740), a memory (750), an I / O interface (760), and a processor (770).

[0100] In another embodiment, the server device (700) may omit at least one of the above components or additionally provide other components.

[0101] The bus (710) can electrically connect the components (720 to 770) to each other. The bus (710) may include circuits for communication (e.g., control messages and / or data) between the components (720 to 770).

[0102] The display (720) can display text, images, videos, icons, or symbols that constitute various content. The display (720) may include a touchscreen and can receive touch, gesture, proximity, or hovering input using an electronic pen or a part of the user's body.

[0103] For example, the display (720) may include a liquid crystal display (LCD), a light-emitting diode (LED) display, an organic light-emitting diode (organic LED) display, a microelectromechanical systems (MEMS) display, or an electronic paper display. The display (720) may be implemented by being included in the server device (700), or implemented separately from the server device (700) but operatively connected to the server device (700).

[0104] The communication circuit (730) can establish a communication channel between the server device (700) and external devices (e.g., user terminals). The communication circuit (730) may also be referred to as an input / output unit. For example, the communication circuit (730) can communicate with external devices by accessing the network (780) via wireless or wired communication.
