[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] To address the safety hazards and low efficiency of existing RSU angle adjustment methods, this embodiment discloses a roadside unit device, such as... Figure 1A and 1B As shown, the roadside unit device includes: a roadside antenna 1, a rotating module (such as...) Figure 1A The diagram shows the roadside antenna and rotating module structure) and intelligent control handheld devices (such as...). Figure 1B (A top-view view of the front of the smart control handheld device shown).

[0035] The rotating module includes a ball gear 21, a motor 22 disposed in the drive wheel 211 of the ball gear, a first Bluetooth communication module (not shown in the figure), and a first controller (not shown in the figure). It is worth noting that, in order to protect the first Bluetooth communication module and the first controller, and to facilitate the first controller to drive and control the electrodes, the first Bluetooth communication module and the first controller can be integrated into the motor.

[0036] The intelligent control handheld device includes an angle adjustment button 31, a second controller (not shown in the figure), and a second Bluetooth communication module (not shown in the figure).

[0037] To finely adjust the angle of the roadside antenna 1, in this embodiment of the invention, the outer gear of the spherical gear is the driven gear 212, and the inner gear is the driving gear 211. The inner surface of the outer gear serves as the tooth surface, and the tooth surface of the outer gear is provided with concave and convex teeth. The outer surface of the inner gear serves as the tooth surface, and the tooth surface of the inner gear is provided with concave and convex teeth. The convex teeth of the driving gear of the spherical gear mesh with the concave teeth of the driven gear, or the concave teeth of the driving gear of the spherical gear mesh with the convex teeth of the driven gear. In this way, when the driving gear of the spherical gear rotates, it can drive the driven gear 212 of the spherical gear to rotate. The roadside antenna is fixedly connected to the driven gear 212 of the spherical gear, and the driving gear 211 of the spherical gear is fixedly connected to the ETC gantry or L-shaped pole. Specifically, the driving gear 211 of the spherical gear is fixed to the ETC gantry or L-shaped pole. The first Bluetooth communication module and the second Bluetooth communication module are connected via Bluetooth. Once the first Bluetooth communication module and the second Bluetooth communication module are connected via Bluetooth, the first controller and the second controller can be connected via Bluetooth.

[0038] The first and second controllers can be, but are not limited to, microcontrollers. The microcontrollers can further be, but are not limited to, MCUs. The MCU can be a standard model, sufficient to fulfill the aforementioned conventional functions of sending angle adjustment signals and driving the motor to rotate the drive wheel of the ball gear. The specific model can be selected based on actual needs and is not limited here. For example, the specific MCU model can be, but is not limited to, Genio 130A (MT7933).

[0039] It should be noted that the second Bluetooth communication module is located inside the smart control handheld device, therefore Figure 1B The dashed line indicates this. Furthermore, Figure 1B The image only shows a top-down view of the intelligent control handheld device. The positions of the modules and the shape of the intelligent control handheld device are only examples and can be adjusted according to the actual situation in practical applications.

[0040] To ensure the stability of the Bluetooth connection, the first and second Bluetooth communication modules mentioned above can be, but are not limited to, Bluetooth 5.0 and above, thereby ensuring an effective connection between the rotating module and the smart control handheld device.

[0041] The angle adjustment button 31 is adapted to trigger an angle adjustment signal in response to a user's operation of pressing the button, and the signal is sent to the first controller via the second controller. It should be noted that the angle adjustment signal includes the angle adjustment direction.

[0042] The first controller drives the motor based on the angle adjustment signal to rotate the driving wheel of the ball gear. The rotation of the driving wheel drives the driven wheel of the ball gear to rotate, and the rotation of the driven wheel drives the roadside antenna to rotate, thereby realizing the fine adjustment of the angle of the roadside antenna.

[0043] It is important to note that, to ensure the stability of the Bluetooth connection and to better reflect actual road conditions, the communication distance between the rotating module and the smart control handheld device should be no less than 50 meters. This allows the smart control handheld device to automatically adjust the angle of the rotating module, thereby adjusting the angle of the roadside antenna, even when the rotating module and the smart control handheld device are at a certain distance.

[0044] As can be seen from the above, the roadside unit device provided by this utility model can intelligently adjust the RSU angle by combining an intelligent control handheld device with a rotation module, without the need for manual climbing multiple times. This effectively avoids the safety hazards caused by manual climbing multiple times and also improves the adjustment efficiency and convenience of RSU angle deviation.

[0045] In some embodiments, such as Figure 1BAs shown, the angle adjustment button 31 includes a sensor and adjustment buttons for tilting, looking down, left, and right (the sensor and microcontroller can be integrated with the adjustment buttons). This allows for angle adjustment of the ball gear from multiple directions, thereby enabling more flexible angle adjustment of the roadside antenna. The sensor is an existing device; a standard model can be selected based on the actual situation, and no limitation is made here. The sensor can further utilize, but is not limited to, an APT8L series capacitive touch sensor chip to fulfill the aforementioned standard function of sending the angle adjustment signal generated by detecting changes in the button's position and sending it to the second controller. The specific model can be selected based on the actual situation, and no limitation is made here. For example, the specific MCU model can be, but is not limited to, Genio 130A (MT7933).

[0046] In this embodiment, the specific signal acquisition and transmission process of the intelligent control handheld device includes: the user triggers any of the adjustment buttons for looking up, looking down, left, and right; the sensor can detect the position change of the button, generate an angle adjustment signal, and send it to the second controller; the second controller sends the angle adjustment signal to the first controller; the first controller drives the motor according to the angle adjustment signal, which in turn drives the drive wheel (i.e., the inner gear) of the ball gear to rotate, thereby driving the driven wheel (i.e., the outer gear) to rotate, thus realizing the fine adjustment of the angle of the roadside antenna.

[0047] In some embodiments, to better achieve the rotation of the driving wheel of the spherical gear driving the rotation of the driven wheel, the inner gear is a complete spherical gear, that is, the inner gear is a single spherical gear. The outer gear is a partial spherical gear. Furthermore, to ensure better meshing between the convex / concave teeth of the driving wheel and the concave / convex teeth of the driven wheel, the missing portion of the outer gear is less than half a sphere. That is, the shape of the outer gear is between a half-spherical gear and a complete spherical gear; specifically, the shape of the outer gear can be, but is not limited to, a three-quarter spherical gear. This allows for better realization of the driving wheel rotating to drive the driven wheel, and the driven wheel rotating to drive the roadside antenna, thereby achieving adjustment of the roadside antenna angle.

[0048] In some embodiments, Figure 2A A top-down view of the second smart control handheld device is shown. Figure 2B A top-down view of the reverse side of the smart control handheld device is shown. (See image.) Figure 2A and 2BAs shown, the smart control handheld device also includes an antenna 32, a power / off button 33, a battery pack 34, a display screen 35, a connection status indicator 36, and a charging port (located inside the smart control handheld device, not shown in the figure). The battery pack 34 (located on the back of the smart control handheld device) is communicatively connected to the antenna 32, the power / off button 33, the display screen 35, the connection status indicator 36, and the charging port (located on the side of the smart control handheld device, not shown in the figure).

[0049] It should be noted that the charging port can be embedded in, but is not limited to, any side of the smart control handheld device. Furthermore, Figure 2A The top front view of the second smart control handheld device shown and Figure 2B The diagram shows a top-down view of the reverse side of the intelligent control handheld device. The positions of the modules and the shape of the intelligent control handheld device are only examples and can be adjusted according to actual needs in practical applications.

[0050] Antenna 32 is adapted to receive ETC signals transmitted by roadside antennas; that is, antenna 32 only includes a signal receiving module. Similarly, antenna 32 can also be, but is not limited to, a 16-element antenna array or a 64-element antenna array.

[0051] The start / stop button 33 is suitable for starting or stopping the smart control handheld device. Specifically, in response to the user triggering the start or stop button, the smart control handheld device can be turned on or off.

[0052] The battery pack 34 is suitable for powering the smart control handheld device, and further, for powering the angle adjustment button 31, the second Bluetooth communication module, the antenna 32, the power on / off button 33, the display screen 35, and the connection status indicator 36 of the smart control handheld device, to ensure the normal operation of the smart control handheld device. The battery pack 34 may use, but is not limited to, a rechargeable lithium battery. Furthermore, to reduce energy consumption, the power of the battery pack 34 may be, but is not limited to, 24 watts.

[0053] The display screen 35 is adapted to display the signal strength of the ETC signal after receiving the ETC signal sent by the antenna board module, thereby facilitating users to promptly check the strength of the ETC signal sent by the roadside antenna. Furthermore, the display screen 35 can be, but is not limited to, an LED display screen.

[0054] The connection status indicator 36 is used to display the Bluetooth connection status between the smart control handheld device and the rotation module. Specifically, when the smart control handheld device and the rotation module are successfully connected, the connection status indicator 36 displays green; when the connection fails, the connection status indicator 36 displays red. In this way, through the connection status indicator 36, users can intuitively determine whether the Bluetooth connection between the smart control handheld device and the rotation module is successful, improving the user experience.

[0055] The charging interface is suitable for connecting to an external power source to charge the battery pack. This enables the creation of a rechargeable smart control handheld device.

[0056] In some embodiments, such as Figure 3A As shown, it also includes a roadside controller. The roadside controller in this embodiment can be customized in shape and size according to actual application scenarios. This embodiment only shows the connection relationships of the various modules of the roadside controller and explains the functions of each module, without showing the specific implementation of the physical object. The roadside controller includes a data transceiver module 41 and a first external interface 42.

[0057] It should be noted that the automatic adjustment function implemented through a smart handheld device can be applied to both traditional RSUs and RSUs with video capture capabilities. In this embodiment, when applied to an RSU with video capture capabilities, Figure 3B A block diagram of another roadside antenna of the roadside unit device is shown, such as Figure 3B As shown, in this embodiment, the roadside antenna 1 further includes a video capture module 11, a data storage module (located inside the roadside antenna, not shown in the figure), and a second external interface 12. The first external interface 42 and the second external interface 12 are connected via a communication cable to realize the communication connection between the roadside controller 4 and the roadside antenna. Furthermore, the communication cable can be, but is not limited to, an RS485 communication cable.

[0058] Since the roadside controller is connected to the roadside antenna, the video capture module 11 is also connected to the data transceiver module 41. At the same time, the video capture module 11 is also connected to the data storage module.

[0059] The data transceiver module 41 is adapted to respond to receiving target vehicle information and mileage information sent by the On-Board Unit (OBU), perform ETC toll deduction, and send a capture command to the video capture module 11. The target vehicle information and mileage information are encrypted to protect vehicle information confidentiality. Specifically, the capture command is broadcast by the RSU. Upon receiving the broadcast, the OBU responds, obtains the OBU's MAC address, and in the next frame, the RSU sends a command to the target OBU to establish a dedicated link. The OBU responds, and thus a dedicated link is established between the RSU and the OBU. The RSU then obtains the vehicle information bound to the OBU and deducts the toll based on the toll rate. Furthermore, after the OBU responds to the RSU, the established dedicated link triggers the video capture module 11 to capture the image.

[0060] The data transceiver module can be an existing conventional data transceiver module; the specific model can be selected according to the needs, and there are no restrictions here.

[0061] The video capture module 11 is suitable for collecting vehicle information when a capture command is received and sending it to the data storage module. The vehicle information may include, but is not limited to, three vehicle attributes: license plate, vehicle color, and vehicle shape.

[0062] The video capture module 11 can use, but is not limited to, a camera with a built-in supplementary light; the specific model can be selected according to the needs. This allows for high-precision acquisition of vehicle information in low-light conditions (such as at night or in dimly lit environments), thereby improving the accuracy of vehicle information collection.

[0063] The data storage module is suitable for storing vehicle information. The data storage module can use, but is not limited to, an SD card. Its main purpose is to store vehicle information so that, in the event of abnormal ETC toll collection issues, the vehicle information stored here can provide complete data and a chain of evidence for subsequent audits of abnormal ETC transactions.

[0064] In some embodiments, Figure 4 This diagram illustrates the connection relationship of the modules of another roadside controller in the roadside unit device of this utility model. The roadside controller in this embodiment can also be set in shape and size according to the actual application scenario. This embodiment of the utility model only shows the connection relationship of each module and explains the function of each module, and does not show the specific implementation form of the physical object.

[0065] like Figure 4 As shown, the roadside controller also includes an equipment status indication module 43 and a card slot 44.

[0066] The equipment status indication module 43 is adapted to display the current operating status of the roadside antenna. Furthermore, the current operating status of the RSU may include, but is not limited to, idle, running, waiting, and fault states. This allows users to easily understand whether the roadside antenna is functioning normally and its current operating status, facilitating timely detection and handling of roadside antenna faults. The equipment status indication module 43 can be a display screen, which may be, but is not limited to, an LED display screen. The specific model can be selected according to actual conditions, and this embodiment of the invention does not impose any limitations.

[0067] Card slot 44 is suitable for installing a PSAM card. The PSAM card is suitable for providing a key during the ETC decryption process. The ETC decryption process is a conventional technology and will not be described in detail here. The PSAM card, short for Pin Secure Access Module Card, is a highly integrated smart card. It is a terminal security control module based on a highly integrated integrated circuit chip, consisting of a storage unit and a processing unit. The storage unit stores data; in this embodiment, it stores the key. The processing unit is responsible for data processing and verification, i.e., decrypting the ETC toll deduction process. Specifically, it can decrypt all encrypted information during the ETC toll deduction process, such as target vehicle information and mileage information.

[0068] The roadside controller 4 described above can be installed in a location that is convenient for users to view or operate, such as in the user's operating room. This embodiment of the utility model does not impose any limitations on this.

[0069] It should be noted that all the modules mentioned above are existing modules, and their specific circuit structures will not be described in detail here. You can choose the specific model of the module according to your actual needs. This utility model does not impose any restrictions on this.

[0070] Based on the components described above, the complete working process of adjusting the roadside antenna angle will be explained below:

[0071] After the roadside antenna is installed and powered on, it sends ETC signals through the antenna board module. Manually turning on the smart control handheld device via the start / stop button module turns it on. The smart control handheld device captures the ETC signal emitted by the roadside antenna and displays the ETC signal strength on the screen. The angle adjustment module detects the ETC signal strength and peak value. Based on the ETC signal strength and peak value, it determines when the signal coverage deviates from the lane's preset signal coverage range, and when the connection status indicator light on the smart control handheld device is green. This indicates that the Bluetooth module (i.e., the second Bluetooth communication module 32) of the smart control handheld device has connected with the rotation module (i.e., the second Bluetooth communication module 32). When the Bluetooth module of the first Bluetooth communication module is successfully connected, the user triggers the angle adjustment button. The sensor responds to the trigger operation by triggering the angle adjustment signal and sends it to the second controller (the controller of the smart control handheld device). The second controller sends the angle adjustment signal to the first controller (the controller of the rotation module). The first controller controls the drive wheel of the ball gear to rotate a preset number of tooth positions (e.g., one tooth position) according to the angle in the angle adjustment signal by driving the drive wheel of the ball gear. The rotation of the drive wheel drives the driven wheel of the ball gear to rotate, and the rotation of the driven wheel drives the roadside antenna to rotate, thereby realizing the fine adjustment of the angle of the roadside antenna by the rotation module.

[0072] The first controller controls the drive wheel of the ball gear to rotate the number of convex teeth according to the angle in the angle adjustment signal by controlling the drive motor. This is preset in the program of the first controller and can be set according to the actual situation. This utility model will not explain this.

[0073] Similarly, in conjunction with the components described above, the complete working process of ETC toll collection through the roadside unit device provided by this utility model is described below:

[0074] Vehicle identification and information recording at the entrance stage: When a target vehicle enters the dedicated ETC lane on the highway, the roadside unit (RSU) above the lane communicates with the on-board unit (OBU) to read the target vehicle's information, including vehicle type, license plate, and vehicle color, and records the vehicle's entrance information, such as the toll station name and entrance time. This information provides the basis for subsequent toll calculation.

[0075] Fee Calculation and Deduction: When a vehicle arrives at the exit, the Roadside Unit (RSU) in the ETC lane broadcasts information. The On-Board Unit (OBU) responds to this broadcast, obtaining the OBU's MAC address. In the next frame, the RSU sends a command to the target OBU to establish a dedicated link. The OBU responds, and a dedicated link is established between the RSU and OBU. The RSU then obtains the vehicle information bound to the OBU, calculates the fee based on the toll rate and mileage, and automatically deducts the fee from the bound ETC user card. Furthermore, after the OBU responds to the RSU, the establishment of the dedicated link triggers the video capture module 11 to capture an image. After successful deduction, the system sends a successful deduction message to the user, informing them of the detailed information of this deduction.

[0076] Furthermore, when the OBU responds to the Roadside Unit (RSU), the video capture module collects the vehicle information of the target vehicle and stores it in the data storage module. The vehicle information of the target vehicle stored here can provide complete data and evidence chain for subsequent audits of abnormal ETC, but it does not participate in the information exchange process of the aforementioned dedicated short-range communication.

[0077] In some embodiments, the roadside antenna 1 further includes a housing, not shown in the figure. In this case, the antenna board module and data storage module are housed within the housing. This effectively prevents water leakage, wind and sand ingress, and other damage to the roadside antenna, thus protecting its internal components and extending its service life.

[0078] Furthermore, the housing includes an upper housing and a lower housing, which are fixed together by bolts. The upper housing may be made of, but is not limited to, a plastic housing, and the lower housing may be made of, but is not limited to, a metal housing.

[0079] In some embodiments, such as Figure 5 As shown, the rotating module also includes a fixing plate 23. One end of the fixing plate 23 is fixedly connected to the outer casing, and the other end of the fixing plate is fixedly connected to the driven wheel of the ball gear, thereby achieving a fixed connection between the roadside antenna and the driven wheel of the ball gear. Furthermore, the outer casing is fixedly connected to one end of the fixing plate using bolts and nuts. Fixing the outer casing of the roadside antenna and the driven wheel of the ball gear with the fixing plate reduces damage to the outer casing caused by the fixed connection, thereby increasing the service life of the roadside antenna and, consequently, the service life of the roadside unit device.

[0080] In some embodiments, such as Figure 6As shown, the rotating module also includes a fixed base 24. One end of the fixed base 24 is fixedly connected to the driving wheel 211 of the ball gear. Specifically, one end of the fixed base 24 and the driving wheel 211 of the ball gear can be fixedly connected by a bearing or a ball joint. The other end of the fixed base 24 is fixed to the ETC gantry or L-pole. It should be noted that the fixed base in this embodiment uses an existing roadside antenna fixed base. When the automatic adjustment function malfunctions, if a traditional fixing method is desired, the original fixed base and connectors can be directly replaced without replacing the antenna, thus improving the flexibility of the roadside unit device.

[0081] Because roadside antennas have a certain weight, instability can easily occur during the adjustment of the rotating module angle. Therefore, to address this issue, in some embodiments, such as... Figure 7 As shown, the rotating module also includes at least one set of springs 25. Each set of springs consists of two springs 25, meaning the springs 25 are arranged in pairs. Therefore, the number of springs 25 is either two or four, or an even number. One end of each spring 25 is fixedly connected to the driven wheel connection end of the fixed plate, and the other end is fixedly connected to the driving wheel connection end of the fixed base. It is worth noting that, to maintain the stability of the roadside antenna, the two springs 25 in one set are parallel and positioned on different planes. This counteracts the elastic and tensile forces generated by the springs 25 on different planes during rotation, thus securing the roadside antenna.

[0082] To effectively prevent the roadside antenna from becoming unstable or falling, and to maintain flexibility while allowing the ball gear to rotate the antenna, in a preferred embodiment, there are two sets of springs, totaling four springs. The springs are made of high-carbon steel with a wire diameter between 0.6-1.2 mm, an outer diameter between 10-20 mm, and a stretchable length of up to 15 cm. Thus, when the ball gear rotates, it drives one of the two parallel springs on different horizontal planes to generate a tensile force, while the other spring generates a spring force. The tensile and spring forces cancel each other out, thus achieving a fixing effect.

[0083] In some embodiments, to allow for automated adjustment of the roadside antenna angle while retaining the capability for manual adjustment or inspection from a higher vantage point, the outer surfaces of the inner gear and the inner gear of the rotating module's ball gear are provided with graduations. This allows the graduated ball gear to provide a reference for manual operation should the automated roadside antenna angle adjustment system malfunction.

[0084] In some embodiments, to improve ease of use, the smart control handheld device may be designed as, but is not limited to, a smart control handle.

[0085] As can be seen from the above, the roadside unit device provided by this utility model can connect to the rotating module (including ball gear) via Bluetooth through an intelligent control handheld device during engineering installation. The angle of the ball gear can be adjusted according to the engineering application, thereby driving the adjustment of the roadside antenna angle. In other words, the RSU angle can be intelligently adjusted by combining the intelligent control handheld device with the rotating module, without the need for manual climbing multiple times. This effectively avoids the safety hazards caused by manual climbing multiple times and also improves the efficiency and convenience of adjusting the RSU angle deviation.

[0086] In addition, the roadside unit device provided by this utility model can collect and store the vehicle information of the current vehicle through the video capture module. In this way, if abnormal ETC toll collection occurs in the future, the vehicle information of the current vehicle stored here can provide complete data and evidence chain for the subsequent audit of abnormal ETC.

[0087] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0088] The various embodiments in this specification are described in a progressive manner. Similar or identical parts between embodiments can be referred to interchangeably. Each embodiment focuses on describing the differences from other embodiments. In particular, the system embodiments are basically similar to the method embodiments, so the description is relatively simple; relevant parts can be referred to the descriptions in the method embodiments.

[0089] The above description is merely an embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
