Additionally, numbers used in the description of this specification (e.g., 1st, 2nd, etc.) are merely identification symbols to distinguish one component from another.

[0030] The present invention will be described in more detail below with reference to the drawings.

[0031] FIG. 1 is a diagram illustrating a system for providing a freight vehicle traffic control service using a weight verification terminal according to an embodiment of the present invention. Referring to FIG. 1, the system for providing a freight vehicle traffic control service using a weight verification terminal (1) may include at least one weight verification terminal (100), a freight vehicle traffic control service providing server (300), and at least one administrative system (400). However, since the system for providing a freight vehicle traffic control service using a weight verification terminal (1) of FIG. 1 is merely an embodiment of the present invention, the present invention is not to be interpreted as being limited by FIG. 1.

[0032] At this time, each component of FIG. 1 is generally connected through a network (network, 200). For example, as shown in FIG. 1, at least one weight verification terminal (100) can be connected to a truck traffic control service provider server (300) through the network (200). And, the truck traffic control service provider server (300) can be connected to at least one weight verification terminal (100) and at least one administrative system (400) through the network (200). Also, at least one administrative system (400) can be connected to the truck traffic control service provider server (300) through the network (200).

[0033] Here, a network refers to a connection structure capable of exchanging information among each node, such as multiple terminals and servers. Examples of such networks include a Local Area Network (LAN), a Wide Area Network (WAN), the World Wide Web (WWW), wired and wireless data networks, telephone networks, and wired and wireless television networks. Examples of wireless data networks include, but are not limited to, 3G, 4G, 5G, 3GPP (3rd Generation Partnership Project), 5GPP (5th Generation Partnership Project), LTE (Long Term Evolution), Wi-Fi, the Internet, LAN (Local Area Network), Wireless LAN (Wireless Local Area Network), WAN (Wide Area Network), PAN (Personal Area Network), RF (Radio Frequency), Bluetooth networks, NFC (Near-Field Communication) networks, satellite broadcasting networks, analog broadcasting networks, and DMB (Digital Multimedia Broadcasting) networks.

[0034] In the following, the term "at least one" is defined as a term including both singular and plural forms, and it will be obvious that even if the term "at least one" does not exist, each component may exist in a singular or plural form and may mean singular or plural. Furthermore, whether each component is provided in a singular or plural form may be changed according to the embodiment.

[0035] The weight verification terminal (100) illustrated in FIG. 1 will be described in detail with reference to FIG. 2. FIG. 2 is a detailed block diagram of a weight verification terminal according to another embodiment of the present invention.

[0036] For convenience of understanding and explanation, in addition to the weight verification terminal (100), some components of the system shown in FIG. 1 are also shown around FIG. 2.

[0037] A weight verification terminal (100) according to an embodiment of the present invention includes a weight measuring terminal (110), a driver terminal (120), a weight sensor (130), and an OBD (140), as shown in FIG. 2.

[0038] The weight measuring terminal (110) measures the real-time weight of the cargo truck by means of a weight sensor (130) and collects real-time driving information of the cargo truck through an OBD (140), and the driver terminal (120) transmits and receives the input of the measured weight and weight verification information through the cargo truck traffic control service providing server (300) and the network (200).

[0039] The weight measuring terminal (110) includes a wireless communication unit (111), a display panel (112), a GPS receiver (113), a control unit (114), a mobile communication unit (115), a weight measuring unit (116), a CAN communication unit (117), and a memory (118).

[0040] The wireless communication unit (111) transmits and receives weight information and driving information to and from the driver terminal (120), the GPS receiver (113) receives the GPS signal and calculates the current location information, and the weight measuring unit (116) measures the real-time weight from the weight sensor (130) installed on the cargo truck.

[0041] The CAN communication unit (117) extracts vehicle data in conjunction with the truck OBD (On-Board Diagnostics), and the control unit (114) analyzes real-time weight information measured by the weight measuring unit (116), current location information calculated by the GPS receiver (113), and real-time driving information extracted by connecting to the truck OBD through the CAN communication unit (117) to determine whether there is a change in weight, stores it in memory (118), and transmits a weight verification request to the truck traffic control service provider server (300) through the mobile communication unit (115).

[0042] Additionally, the control unit (114) can transmit weight information measured by the weight measuring unit (116) and weight verification information transmitted and received via the mobile communication unit (115) to the driver terminal (120) via the wireless communication unit (111). This is to allow the truck driver to determine and verify whether it is possible to pass the next overload enforcement system without stopping. Meanwhile, the weight measuring terminal (110) can input weight measuring information and display weight verification information independently without being connected to the driver terminal through the display panel (112).

[0043] At least one driver terminal (120) may be a driver's terminal capable of inputting weight measurement information and displaying weight verification information using a webpage, app page, program, or application related to a freight vehicle traffic control service using a weight verification terminal. For example, as a wireless communication device that ensures portability and mobility, it may include all types of handheld-based wireless communication devices such as navigation systems, smartphones, smartpads, tablet PCs, etc.

[0044] The OBD (140) is a device for self-diagnosing a vehicle and is used to connect to the vehicle from the outside to diagnose faults and extract vehicle information. Control modules (ECMs) such as the vehicle's ECU (Electric Control Unit), TCU (Transmission Control Unit), ACU (Airbag Control Unit), and ABS (Anti-lock Braking System) share vehicle information using CAN (Controller Area Network) communication, and by connecting to the CAN through the OBD, it becomes possible to extract vehicle information provided by each control module. According to one embodiment of the present invention, the weight measuring terminal (110) can collect driving information such as the vehicle speed (SPEED), brake operation (BRAKE), and steering (STEERING) by connecting to the OBD connector of the cargo vehicle via wired or wireless connection through the CAN communication unit (117).

[0045] At least one truck traffic control service providing server (300) may be a server that provides a traffic control service web page, app page, program, or application using a weight verification terminal. Additionally, the truck traffic control service providing server (300) may be a server that reviews weight changes based on weight verification information transmitted from at least one weight verification terminal (100) and determines whether to pass without inspection or weigh the vehicle with inspection.

[0046] Here, traffic control means verifying existing weight information to permit or approve passage without inspection, or suspecting overloading and instructing the vehicle to pass through an overload enforcement system for inspection. To this end, the cargo vehicle traffic control service providing server (300) may be a server that stores at least one parameter and formula for traffic control judgment.

[0047] Meanwhile, the truck traffic control service provider server (300) can transmit the traffic control judgment result to the road electronic display board (310) for display and transmit it to the overload enforcement system (320) to prepare for the inspection of the truck subject to inspection. In addition, the truck traffic control service provider server (300) can be integrated with the operating system of a checkpoint or highway entrance toll booth where the overload enforcement system (320) and the road electronic display board (310) are installed.

[0048] Referring to FIG. 2, the freight vehicle traffic control service providing server (300) may be implemented as a computer that includes a processor, memory, and a database, and can connect to a remote server or terminal via a network. Here, the computer may include, for example, a laptop, desktop, laptop, workstation, server, etc. equipped with a web browser.

[0049] At least one administrative system (400) may be a terminal of a relevant ministry that uses a web page, app page, program, or application related to the management service of the relevant ministry, overload enforcement, and restricted vehicle operation permit service in relation to the operation of a freight vehicle. Here, the restricted vehicle operation permit service refers to a service that obtains permission from the Ministry of Land, Infrastructure and Transport in advance for the driving route and transport weight in situations where a vehicle must transport cargo heavier than a standard freight vehicle. The freight vehicle traffic control service server (300) may use the restricted vehicle operation permit result information to approve passage without inspection if there is no change in the application information and weight.

[0050] And, at least one administrative system (400) may be a terminal that comprehensively stores and manages information on truck overload enforcement systems operated by each management agency, namely the National Road Management Office and the Road Corporation, which are divided into general national roads and expressways.

[0051] FIG. 3 is a drawing for explaining the type of overload enforcement system (320) that can be passed while a cargo truck is in operation and the type of electronic scale used to measure the weight of the cargo truck in the overload enforcement system.

[0052] Referring to FIG. 3(a), after loading the cargo, the truck driver can measure the weight of the cargo himself by passing through an authorized weighing station or a private weighing station (321). Afterward, if the truck driver travels on a highway, he can be permitted to drive on the highway after passing through a low-speed weighbridge (322) at an entrance toll booth to verify that he is not overloaded. On the other hand, if he travels on a general national road, he may be randomly selected by a mobile enforcement team (323) and subjected to a weight inspection after stopping. In the future, multiple high-speed weighbridges (324) capable of measuring weight while driving at high speed may be installed on the main lines of general national roads and highways, and the truck driver may be directly inspected by passing through multiple high-speed weighbridges or selected as suspected of overloading and subjected to additional inspection at a checkpoint. Here, the truck driver may not pass through each overload inspection system only once, but may be subjected to duplicate inspections in various cases depending on the driving route.

[0053] Figure 3(b) is a diagram illustrating the types of electronic scales for measuring the weight of a cargo truck that can be used in an overload control system (320) according to an embodiment of the present invention.

[0054] As shown in Fig. 3(b), the weighing machine is applied to an authorized weighing station or a private weighing station (321), and is in the form of a scale on which the entire truck can be placed, and when the truck is placed on the weighing machine and stops, the total weight is measured.

[0055] As shown in Fig. 3(b), the mobile axle loader is used by the mobile enforcement team at the mobile checkpoint (323), and is in the form of a scale on which each wheel of a cargo truck can be placed. When a cargo truck is placed on the mobile axle loader and stops, the weight of each wheel is measured and the total weight is measured by adding them up.

[0056] As shown in Fig. 3(b), the low-speed axle load scale is applied to the highway entrance toll booth (322), and when a truck passes by at a low speed (within 20 km / h), the weight of each wheel is measured and the total weight is measured by summing them.

[0057] As shown in FIG. 3(b), the high-speed axle load scale is applied to the main lanes (324) of highways and general roads, and when a cargo truck passes by at high speed, the weight of each wheel is measured and the total weight is measured by summing them. The application method of the high-speed axle load scale may vary depending on the accuracy; high-accuracy high-speed axle load scales are used for direct enforcement, while low-accuracy high-speed axle load scales are used for screening vehicles suspected of overloading. If a vehicle is screened as suspected of overloading, it is instructed to bypass the main lane and pass through a screening vehicle enforcement checkpoint.

[0058] Figure 4 is a diagram illustrating a weight sensor used in the weight verification terminal of Figure 2.

[0059] The weight sensor can be implemented as a plurality of weight sensors installed on the leaf springs and air springs constituting the suspension system of a cargo vehicle, which measure physical quantities responding to weight changes and convert them into weight.

[0060] Weight sensors used in leaf spring suspension systems may be equipped with angle sensors, position sensors, strain sensors, load cells, etc., which measure changes in the angle of the leaf spring, changes in body height, or changes in strain that increase or decrease according to changes in weight. Additionally, weight sensors used in air spring suspension systems may be equipped with pneumatic sensors, position sensors, angle sensors, load cells, etc., which measure changes in the pressure or height of the air spring that increase or decrease according to changes in weight.

[0061] Here, for use in a weight verification terminal, it is desirable to use a sensor capable of measuring both the axle weight and the total weight of the cargo truck. If a sensor capable of measuring only partial load weight or total weight is used, weight verification is impossible when the axle weight exceeds enforcement standards because the axle weight cannot be measured even if a weight change is detected.

[0062] FIG. 5 is a diagram illustrating the process of transmitting and receiving data between a weight verification terminal (100) and a truck traffic control service providing server (300) included in a truck traffic control service providing system using the weight verification terminal of FIG. 1 according to an embodiment of the present invention. Hereinafter, an example of the process of transmitting and receiving data between each component will be described through FIG. 5, but the present invention is not to be interpreted as being limited to such an embodiment, and it is obvious to those skilled in the art that the process of transmitting and receiving data shown in FIG. 5 may be changed according to various embodiments described above.

[0063] Referring to FIG. 5, the weight verification terminal (100) determines whether to approach an overload enforcement system (320) to be passed by using real-time location information measured by the GPS receiver (113). Here, the determination of approach may use a conventional method of setting a geo-fencing zone for each overload enforcement system, storing zone information of the entire overload enforcement system in a database, and analyzing real-time location information and each zone information to determine whether to enter the geo-fencing. According to another aspect, if the application of the driver terminal (120) includes a navigation function, a method of specifying a truck driving route and analyzing only the overload enforcement systems within the route may be used.

[0064] When the weight verification terminal (100) approaches the overload enforcement system (320) to be passed, it collects information on whether the current weight of the cargo truck has changed, location information, and information on passing the previous overload enforcement system to generate weight verification information, and transmits it to the cargo truck traffic control service provider server (300) to request weight verification. The reason for simply determining whether the weight has increased without integrating and managing real-time cargo truck weight and location information and the entire driving route information in a single system for weight verification is to propose a method that uses only the minimum necessary information for the protection of personal information. The protocol form of the weight verification information according to an embodiment of the present invention is as shown in Table 1 below, but is not limited thereto.

[0065] No. Field detail example 1 Vehicle Information Vehicle ID, communication IP, etc. 123ga4567,123.12.13.123 2 Verification request time "YYYYMMDDHHmmss" 20230101090115 3 Previous Pass Information Previous passing overload enforcement system ID WS0163 or None 4 Previous passing time "YYYYMMDDHHmmss" 20230101081110 5 Whether there is a change in weight Weight increase (Y), No weight increase (N) Y or N 6 Restricted vehicle operation Permitted (A), Unpermitted (B) A or B 7 Current location X hardness 1283214 8 Current location Y latitude 4566208

[0066] The truck traffic control service provider server (300) analyzes the received weight verification information to determine whether there is information regarding the previous overload enforcement system (320) passing. At this time, if there is no previous passing information, the inspection weighing of the truck is determined, and the weight verification result can be transmitted again along with the inspection location. On the other hand, if there is previous passing information, the weight change is reviewed to determine whether additional cargo was loaded after passing the previous overload enforcement system (320). If there was an increase in the truck's weight, the inspection weighing is determined again, and if there was no increase in weight, passing without inspection can be approved.

[0067] The weight verification result analyzed as passing through inspection or without inspection is transmitted to the weight verification terminal (100), stored in the memory and database of the cargo truck traffic control service provider server (300), and can be displayed on a road electronic display board (VMS) for guidance or transmitted to an administrative system.

[0068] FIG. 6 is a diagram illustrating a method for determining whether there is an actual change in weight in real time using the total weight measurement value in the control unit (114) of the weight measuring terminal (110) of FIG. 2 according to a preferred embodiment of the present invention.

[0069] Figure 6(a) is a graph illustrating the weight change of a cargo truck expected to pass without inspection as described. At this time, it can be seen that there is no increase in weight from the time the cargo truck passes the first overload enforcement system and inputs weight information after loading 40 tons of cargo until the next overload enforcement system to pass.

[0070] Figure 6(b) is a graph illustrating the weight change of a cargo truck expected to receive an inspection order as described. At this time, it can be seen that the weight increase occurred after the cargo truck passed through the initial overloading inspection system and entered the weight information after loading 40 tons of cargo.

[0071] Specifically, the control unit (114) can determine whether there is a change in the weight of the cargo truck using the following mathematical formula 1.

[0072]

[0073] Here, GVW roi is a weight increase judgment index, and GVW p is the gross weight of the cargo truck measured by the previous overload enforcement system, and GVW c is the current gross weight of the cargo truck measured in real time by the weight measuring terminal, and ER is the error rate (%) of the weight measuring sensor.

[0074] If weight increase occurs, GVW roi It becomes greater than 1, and if no increase in weight occurs, it becomes less than 1.

[0075] Considering that the error rate of a typical weighing sensor in Fig. 6(b) is within 10%, GVW p is 40 tons, GVW c If we substitute 45 tons and ER 10 into Equation 1, GVW roi It is calculated as (45-40) / (40*10 / 100) and becomes 1.25, which is analyzed as an increase in weight.

[0076] FIG. 7 is a diagram illustrating a driver terminal (120) screen and a road electronic display board (310) (VMS, Variable Message Sign) displaying non-inspection passing approval information and inspection instruction information according to a preferred embodiment of the present invention, and the method of displaying the terminal and the road electronic display board that received the weight verification information is not limited thereto.

[0077] As shown in FIG. 7(a), a driver terminal or road electronic display board that has received information on passing without inspection approval can display information on passing without inspection weight verification.

[0078] As shown in Fig. 7(b), a driver terminal or road electronic display board that receives vehicle inspection instruction information can display vehicle inspection instruction weight verification information.

[0079] FIG. 8 is a drawing provided to explain a method for providing a freight vehicle traffic control service using a weight verification terminal according to a preferred embodiment of the present invention.

[0080] First, after the truck driver passes the initial overload enforcement system, the weight measurement result is entered and stored through the driver terminal (120) (S100).

[0081] Afterwards, while driving the cargo truck, the approach to the next overload enforcement system (320) to be passed is determined, and weight verification information is transmitted to the cargo truck traffic control service provider server (300) at a distance of 2 km to request weight verification (S200).

[0082] Then, the truck traffic control service provider server (300) analyzes the received weight verification information to determine whether to pass without inspection or to inspect the vehicle, and transmits the weight verification result (S300).

[0083] Specifically, 1) determine whether there is information on passing the previous overload enforcement system, and 2) review weight changes to determine whether additional cargo was loaded after passing the previous overload enforcement system, and determine whether to weigh the vehicle or pass without inspection based on whether the vehicle weight has increased, thereby generating a weight verification result and transmitting it.

[0084] The weight verification terminal (100) receives the weight verification result and displays the result on the driver terminal (120). Meanwhile, the weight verification result can also be displayed on the overload enforcement system (320) and the road electronic display board (310) (S400).

[0085] Furthermore, although preferred embodiments of the present invention have been illustrated and described above, the present invention is not limited to the specific embodiments described above. It is understood that various modifications can be made by those skilled in the art without departing from the essence of the invention as claimed in the claims, and such modifications should not be understood individually from the technical spirit or perspective of the present invention.
