[0097] S5. The ETC inspection vehicle performs parking space matching through RFID technology to confirm the location of the parking space where the identified vehicle is parked;

[0098] S6. The ETC inspection vehicle uploads the vehicle information and the road image to the designated parking cloud platform; the designated parking cloud platform processes the vehicle information and the road image through a set process, obtains the billing information of the identified vehicle, and sends the billing information to the edge server of the ETC inspection vehicle;

[0099] S7, the ETC inspection vehicle performs ETC deduction processing on the identified vehicle equipped with ETC according to the billing information and the overdue payment order; if the identified vehicle is not equipped with ETC, the road test recovery process is initiated;

[0100] S8. The ETC middleware cloud platform sends the deduction success information and saves it in the obu of the on-board ETC of the identified vehicle, and sends the deduction success information to the ETC app of the owner of the identified vehicle.

[0101] In this embodiment, in step S1, qualified unpaid orders are screened through a designated parking cloud platform to obtain overdue orders; the overdue orders are pushed to the ETC middleware cloud platform in real time through the designated parking cloud platform; wherein, the designated parking cloud platform adopts the Lianlu Smart Parking Cloud Platform.

[0102] Specifically, Figure 4 As shown, the designated parking cloud platform first screens out eligible overdue orders and pushes these orders to the ETC middleware cloud platform in real time.

[0103] In this embodiment, in step S2, after receiving the overdue payment order, the ETC middleware cloud platform immediately synchronizes it to the edge server of the ETC inspection vehicle; the edge server of the ETC inspection vehicle stores the received overdue payment order;

[0104] Specifically, after receiving the overdue payment order, the ETC middleware cloud platform will immediately synchronize it to the edge server of the ETC inspection vehicle (i.e., the inspection vehicle itself) to ensure the real-time nature of the overdue payment order data; the edge server of the ETC inspection vehicle will also store the received overdue payment order.

[0105] In this embodiment, in step S3, the ETC inspection vehicle performs inspection along a preset route through an unmanned driving control system;

[0106] Specifically, Figure 7 and Figure 8 As shown in the figure, the decision-making and path planning steps of the ETC inspection vehicle are:

[0107] S31, the ETC inspection vehicle receives the task instruction issued by the designated parking cloud platform;

[0108] Specifically, the ETC inspection vehicle first receives the task instructions from the designated parking cloud platform, including key information such as inspection area, inspection time, and task priority.

[0109] S32, collecting environmental information around the vehicle in real time through vehicle-mounted sensors;

[0110] Specifically, through a variety of on-board sensors (such as lidar, cameras, millimeter-wave radar, etc.), environmental information around the vehicle is collected in real time, including road conditions, obstacle locations, traffic flow, etc.

[0111] S33, determining the corresponding relationship between the current position of the ETC inspection vehicle and the map through GPS positioning and map matching technology;

[0112] Specifically, GPS positioning and map matching technology are used to determine the correspondence between the vehicle's current position and the map, providing basic data for subsequent decision-making and route planning.

[0113] S34. Predict and analyze potential dangers and traffic flow based on the collected environmental information;

[0114] S35. Make behavioral decisions and route planning for ETC inspection vehicles based on task instructions and environmental analysis results;

[0115] Specifically, according to the task instructions and environmental analysis results, the vehicle behavior decisions (such as acceleration, deceleration, steering, obstacle avoidance, etc.) and path planning are made. Path planning will comprehensively consider multiple factors such as road conditions, traffic rules, parking space distribution and task priority to generate the optimal driving path.

[0116] S36, smoothing and optimizing the generated path by setting a smoothing strategy and an optimization strategy;

[0117] Specifically, the generated path is smoothed and optimized to ensure the continuity and feasibility of the path and reduce the occurrence of sharp turns and frequent lane changes.

[0118] Among them, a B-spline curve or a Bezier curve is used for smoothing; the expression of the B-spline curve is:

[0119]

[0120] Where P(t) is a point on the curve; B i (t) is the basis function; P i It is the control point.

[0121] Use optimization algorithms such as gradient descent or simulated annealing to optimize the path; the expression of the gradient descent optimization algorithm is:

[0122]

[0123] Where θ is a parameter; η is the learning rate; J(θ) is the cost function.

[0124] S37, converting the formulated behavior decision into a motion control instruction;

[0125] Specifically, the decision results are converted into specific motion control instructions, such as throttle opening, braking force, steering angle, etc., for use by the vehicle actuators.

[0126] Among them, the PID control algorithm is used to generate control instructions such as throttle opening and braking force. The PID control expression is:

[0127]

[0128] Where u(t) is the control input; e(t) is the error; K p , K i , K d They are proportional, integral, and differential coefficients respectively.

[0129] S38, the ETC inspection vehicle drives according to the motion control instruction and performs the predetermined inspection task;

[0130] S39. During the execution of the task, the on-board sensors continuously monitor environmental changes and upload the monitoring results to the designated parking cloud platform in real time; the designated parking cloud platform sends new instructions to the ETC inspection vehicle or adjusts the original decision and route planning based on the uploaded data and task execution status;

[0131] S310, after the task is completed, the efficiency and effect of the task execution are evaluated;

[0132] Specifically, after the task is completed, the efficiency and effectiveness of the task execution are evaluated, including indicators such as inspection coverage, path rationality, and time consumption.

[0133] S311. Record all data during the task execution and upload them to the designated parking cloud platform for subsequent analysis and optimization.

[0134] In this embodiment, in step S4, the ETC inspection vehicle collects and processes road images in real time through the AI ​​recognition system to obtain vehicle information of the identified vehicle;

[0135] Specifically, Figure 5 and Figure 6 As shown, the steps of environmental perception and data collection and processing are:

[0136] S41. Collect environmental information around the vehicle in real time through the laser radar, camera, millimeter-wave radar and ultrasonic sensor carried by the ETC inspection vehicle to obtain original collected data;

[0137] Specifically, LiDAR, cameras, millimeter-wave radar and ultrasonic sensors begin to collect real-time environmental information around the vehicle. LiDAR provides high-precision 3D point cloud data, cameras capture high-definition images, millimeter-wave radar measures distance and speed, and ultrasonic sensors are used to detect obstacles at close range.

[0138] S42, performing cropping, resizing and denoising preprocessing on the collected original data to obtain preprocessed sensor data;

[0139] Specifically, the collected raw data will go through preprocessing steps, including cropping, resizing (adjusting the image size), denoising and other operations to improve the efficiency and accuracy of subsequent processing.

[0140] Among them, the cropping process is to crop out irrelevant or redundant data areas according to actual application requirements and sensor characteristics. For example, for lidar data, a region of interest (ROI) can be set and only the point cloud data in the region is retained.

[0141] Resizing is the process of adjusting the image size to fit the input requirements of the subsequent processing algorithm. This usually involves image scaling operations, which can use methods such as bilinear interpolation or nearest neighbor interpolation. The mathematical expression for resizing is:

[0142] I resized (x,y)=I original (scale x x, scale y y)

[0143] In the formula, I original is the original image; I resized is the resized image; scale x and scale y are the scaling factors for the horizontal and vertical directions respectively.

[0144] Denoising is the process of applying filtering algorithms to remove noise interference in data. For image data, Gaussian filtering, mean filtering, etc. can be used. For lidar data, statistical filtering or voxel filtering can be used to remove noise and outliers.

[0145] S43, fusing the preprocessed sensor data through a sensor fusion algorithm to obtain fused data;

[0146] Specifically, advanced sensor fusion algorithms (such as Kalman filtering, particle filtering, etc.) are used to fuse data from different sensors to obtain fused data.

[0147] Among them, the Kalman filter fusion algorithm is used for state estimation and smooth motion trajectory of continuous data. Kalman filter minimizes the estimation error by recursively updating the state estimation and covariance matrix.

[0148] The particle filter fusion algorithm is used in complex or nonlinear scenarios. The particle filter simulates the system state through a large number of particles and updates the particle weights according to the observed values ​​to achieve more robust data fusion. Its key steps include initializing particles, predicting particle states, updating particle weights, resampling, and estimating system states.

[0149] Fusion processing combines time synchronization, spatial alignment and other methods to fuse the data of different sensors in a unified coordinate system. For example, the data of different sensors can be aligned using timestamps, and the data of different sensors can be converted to the same reference coordinate system using coordinate transformations (such as rotation matrices and translation vectors).

[0150] S44, constructing a three-dimensional environment model according to the fused data;

[0151] Specifically, based on the fused sensor data, a three-dimensional environment model or a bird's-eye view (BEV map) around the vehicle is constructed to enable a more intuitive understanding of the scene.

[0152] The 3D environment model uses a point cloud processing library (such as PCL) to process the fused lidar data to generate a 3D point cloud model, which usually involves operations such as point cloud filtering, segmentation, registration, and surface reconstruction.

[0153] S45, processing the fused data by a computer vision algorithm to obtain vehicle information; monitoring the occupancy status and time of the parking space by a geomagnetic device to obtain vehicle parking space occupancy information;

[0154] Specifically, computer vision algorithms are used to process image data to achieve license plate recognition, vehicle detection, etc. At the same time, geomagnetic equipment is used to monitor the occupancy status and time of berths.

[0155] Wherein, in the process of processing the fused data by a computer vision algorithm to obtain the vehicle information, the steps of identification processing are:

[0156] S451, performing denoising and enhancement preprocessing on the captured vehicle image;

[0157] Specifically, the captured vehicle images are preprocessed by denoising, enhancing, etc. to improve the image quality.

[0158] S452, extracting vehicle features of the identified vehicle through a deep learning network;

[0159] Specifically, a deep learning network (such as a convolutional neural network (CNN)) is used to extract vehicle features, including license plate number, vehicle model, color, etc.

[0160] S453: Based on the extracted vehicle features, perform vehicle identification through a classifier and output the vehicle information.

[0161] Specifically, based on the extracted features, a classifier (such as a support vector machine (SVM), a neural network, etc.) is used to perform vehicle recognition and output vehicle information.

[0162] S46. Upload the vehicle information and the vehicle parking space occupancy information to a designated parking cloud platform in real time.

[0163] Specifically, all key data collected (including license plate number, vehicle type, parking space status, parking time, etc.) will be uploaded to the designated parking cloud platform in real time. The designated parking cloud platform will further process this data for management functions such as parking fee settlement and parking space monitoring.

[0164] In this embodiment, in step S5, the ETC inspection vehicle performs parking space matching through RFID technology to confirm the location of the parking space where the identified vehicle is parked;

[0165] Specifically, Fig. 9 As shown, the steps for berth matching confirmation are:

[0166] S51. Install a unique RFID tag on each berth;

[0167] Specifically, a unique RFID tag is installed on each berth, and the tag contains the berth number, location information, etc.

[0168] S52, read the RFID tag information on the berth in real time through the RFID reader / writer on the ETC inspection vehicle;

[0169] S53: Match and confirm the vehicle information of the identified vehicle with the berth information read by the RFID.

[0170] Specifically, the vehicle identification result is matched with the parking space information read by RFID. When the inspection vehicle passes by the parking space, the system simultaneously obtains the vehicle image and RFID tag information. By comparing the vehicle position with the RFID tag position, combined with information such as timestamp, the vehicle and parking space are accurately matched.

[0171] In this embodiment, in step S6, the ETC inspection vehicle uploads the vehicle information and the road image to the designated parking cloud platform; the designated parking cloud platform processes the vehicle information and the road image through a set process, obtains the billing information of the identified vehicle, and sends the billing information to the edge server of the ETC inspection vehicle.

[0172] In this embodiment, in step S7, the ETC inspection vehicle performs ETC deduction processing on the identified vehicle equipped with ETC according to the billing information and the overdue payment order; if the identified vehicle is not equipped with ETC, the road test recovery process is started;

[0173] Specifically, Figure 4 As shown, the ETC inspection vehicle edge server stores these overdue payment orders. During the inspection process, the inspection vehicle will read the OBU information loaded on the vehicle through the vehicle-mounted ETC antenna, and query whether the vehicle has overdue payment information on the edge server of the ETC inspection vehicle through the ETC antenna module. If there is overdue payment information, it will be transferred to the third-party deduction channel through the ETC middleware cloud platform, and the bank card associated with etc will be deducted. If the identified vehicle is not equipped with ETC, the reading fails or the tag is invalid, the road test recovery process is started.

[0174] In this embodiment, in step S8, the ETC middleware cloud platform sends down and saves the deduction success information in the obu of the on-board ETC of the identified vehicle, and sends the deduction success information to the ETC app of the owner of the identified vehicle.

[0175] Specifically, once the user completes the supplementary payment, the ETC inspection vehicle edge server will push the successful deduction information back to the ETC middleware cloud platform to ensure timely feedback of the information. The successful deduction information is then written to the on-board OBU module through the downlink channel, and the successful deduction information is sent to the ETC app that identifies the owner of the vehicle. For vehicles in abnormal conditions (such as blacklisted vehicles), the bank's deduction center or settlement center will handle the deduction failure, including deduction query, black and white gray list verification, and ensure that the ETC channels in various provinces in the country can be opened to ensure the smooth progress of the deduction process.

[0176] In summary, the present invention obtains overdue payment orders by screening qualified unpaid orders through a designated parking cloud platform; pushes the overdue payment orders to the ETC middleware cloud platform in real time through the designated parking cloud platform; after receiving the overdue payment orders, the ETC middleware cloud platform immediately synchronizes them to the edge server of the ETC inspection vehicle; the edge server of the ETC inspection vehicle stores the received overdue payment orders; the ETC inspection vehicle inspects along the preset route through an unmanned driving control system; the ETC inspection vehicle collects and processes road images in real time through an AI recognition system to obtain vehicle information for identifying vehicles; the ETC inspection vehicle matches parking spaces through RFID technology to confirm that the identified vehicle is parked The location of the parking space; the ETC inspection vehicle uploads the vehicle information and the road image to the designated parking cloud platform; the designated parking cloud platform processes the vehicle information and the road image through a set process, obtains the billing information of the identified vehicle, and sends the billing information to the edge server of the ETC inspection vehicle; the ETC inspection vehicle performs ETC deduction processing on the identified vehicle equipped with ETC according to the billing information and the arrears order; if the identified vehicle is not equipped with ETC, the road test recovery process is started; the ETC middleware cloud platform sends and saves the deduction success information in the obu of the on-board ETC of the identified vehicle, and sends the deduction success information to the ETC app of the owner of the identified vehicle. The present invention can automatically identify road test vehicles, support ETC road test recovery, realize efficient and accurate automatic charging, improve road traffic management and charging efficiency; and reduce labor costs and error rates. The present invention effectively curbs evasion by supporting ETC road test recovery and automatic charging, and improves the fairness and transparency of highway toll management.
