[0025] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Combine the following Figure 1 The invention describes a closed-loop control method for automated daily maintenance management of a highway, comprising: step 100, inspecting the highway through a preset automated data collection device, generating inspection data, and intelligently adjusting the inspection frequency according to the real-time collected road condition, road age and traffic volume data, to perform dynamic inspections.

[0027] In the present invention, the automated acquisition equipment includes a mobile trolley and a positioning device and an industrial camera installed on the mobile trolley; Acquiring location information through the positioning device, and collecting road surface information of the highway through the industrial camera; The mobile vehicle moves along the set route to complete highway inspections and generate inspection data.

[0028] Specifically, the automated data acquisition equipment is connected to the vehicle power supply of the mobile vehicle, the GPS antenna is magnetically installed on the roof to obtain location information, the vehicle suction cup is used to install the bracket at the rear and rear windshield, and the bracket is leveled with a bubble level. A high-frame rate industrial camera is set up at a fixed height above the bracket. After the camera and GPS are connected, the equipment can be started and daily inspections can begin. During the inspection process, image information of the highway is continuously collected and location information is assigned to the image based on real-time positioning.

[0029] Intelligently adjust inspection frequency based on real-time collected road conditions, road age and traffic volume data to conduct dynamic inspections, including: Build a daily inspection frequency database through real-time collection of road conditions, road age and traffic flow; Calculate the optimal inspection frequency based on the daily inspection frequency library combined with a preset route condition threshold; Adjust the working frequency of the automatic collection equipment according to the optimal inspection frequency.

[0030] In the present invention, the process of adjusting the working frequency of the automatic acquisition device includes: Data preparation is performed to collect the road condition index 𝐶, road age 𝐴, and average daily traffic volume 𝑇 in real time, and the raw data is cleaned, formatted, and preprocessed. The raw data set is divided into a training set and a test set. The training set is used for model training, while the test set is used for model evaluation.

[0031] Referring to Table 1, the road condition is classified into five levels according to the road condition index 𝐶.

[0032] Table 1 Pavement technical condition classification

[0033] For each road condition level, a separate random forest model is built. Random forests consist of multiple decision trees, each of which is trained on a subset of the data to reduce the risk of overfitting. The random forest algorithm is used to train each level of the data set with the goal of predicting the inspection frequency.

[0034] The random forest algorithm can automatically estimate parameters, which mainly refer to the structure of each tree (such as the conditions for node splitting) and the number of trees in the entire forest. These parameters are further optimized through cross-validation.

[0035] Compare the predicted values ​​of the model with the true values ​​in the test set and calculate the performance indicator of the model, the root mean square error ( ) and the coefficient of determination .

[0036] .

[0037] .

[0038] in, is the actual inspection frequency, is the inspection frequency predicted by the model, N is the number of samples in the test set, It is the average value of the actual inspection frequency.

[0039] If the model Lower and If the value is high, it means that the model performs well on the test set and has good generalization ability. Otherwise, you may need to return to adjust the model parameters.

[0040] Although random forests do not directly generate output in the form of formulas, their predictions can be used directly to guide the adjustment of inspection frequency. Different random forest models will be generated for different road condition levels, so the prediction of inspection frequency will also vary according to different road condition levels. For each road condition level, the random forest model will output a function that predicts the inspection frequency. For example, for areas with "excellent" road conditions, the inspection frequency formula can be expressed as follows.

[0041] .

[0042] When the road condition index is 85, the road age is 5 years, and the average daily traffic volume is 2,000 vehicles / day, the inspection frequency can be expressed as follows.

[0043] .

[0044] Step 200: Determine the location and quantity of defects within a set unit length based on the inspection data.

[0045] Specifically including: generating an inspection log based on the inspection data according to the inspection date; Acquire disease images within a set unit length from the inspection log; The number of diseases is obtained from the disease image through a preset image recognition model, and the disease position is obtained according to the position information of the mobile vehicle when the disease image is obtained.

[0046] In the present invention, the inspection record form generated by the equipment is automatically imported into the system to generate an inspection log, which records the detailed equipment inspection data every 3 meters and every kilometer, including the location and number of cracks, fissures, potholes, and repair-type defects. The system automatically calculates the total amount of defects, crack rate and repair rate of a single inspection.

[0047] Step 300: classify the diseases according to the disease locations and the number of diseases, and if it is determined based on the classification results that the degree of damage caused by the diseases exceeds a preset dynamic threshold, the corresponding disease conditions are entered into the disease record.

[0048] Specifically, it includes: classifying the diseases according to the disease locations and the number of diseases, and determining the average damaged length and damaged area of ​​the diseases based on the classification results; When the average damaged length or damaged area of ​​the disease exceeds the preset dynamic threshold, the corresponding disease situation will be recorded in the disease record; The dynamic threshold is dynamically adjusted according to the changes in the damaged length and damaged area.

[0049] In the present invention, various types of diseases found during inspections are classified and treated, and the threshold is dynamically adjusted according to the degree of damage and entered into the disease record. Referring to Table 2, taking asphalt pavement diseases as an example, the diseases are divided into 21 types, and different entry thresholds are set according to the degree of damage. When the average damaged length / area of ​​the disease found during inspections is greater than the set threshold, it is automatically entered into the disease record.

[0050] Table 2 Classification and treatment of asphalt pavement defects

[0051] According to the disease data collected by the automated equipment, the initial storage threshold is set, and it is dynamically adjusted according to the real-time disease data to adapt to different road conditions and environmental conditions. When the average damaged length or area of ​​the disease collected exceeds the corresponding dynamic threshold, the system automatically enters the disease information (including type, location, size, time, etc.) into the disease database.

[0052] Assumptions Indicates The entry threshold of the disease-like and Respectively represent the most recent period of time The changes in the average damaged length and area of ​​the disease, and is the adjustment coefficient, then the adjustment formula of the dynamic threshold can be expressed as follows.

[0053] .

[0054] in, and It can be determined based on historical data and engineering experience. Usually and The values ​​are all within the range of 0-1. The storage threshold is the change in the damaged length and area of ​​a certain type of disease in the initial state. In the actual identification and collection process, the damaged length and area will change accordingly according to different road conditions and environmental conditions. The dynamic threshold is determined based on the average damaged length or area of ​​the disease identified and collected combined with the adjustment coefficient.

[0055] Step 400: Generate a disease notification based on the disease log and send it to the maintenance work area for on-site repair.

[0056] The disease information in the disease log is summarized according to each kilometer section, and a disease notification form is formed and sent to the maintenance work area for on-site repairs. After receiving the disease log, the maintenance work area will carry out on-site repairs based on the specific location and number of diseases, and conduct inspections after the repairs are completed.

[0057] Step 500: Based on the results of on-site maintenance, acceptance inspection is carried out through automated data collection equipment to calculate the repair compliance rate. When the repair compliance rate exceeds the standard repair rate, the repair acceptance is completed to form a fully automatic closed-loop management.

[0058] Specifically, after completing on-site maintenance, based on the results of on-site maintenance, images are collected in the maintenance area through automated acquisition equipment for acceptance inspection; The repair compliance rate is calculated using a preset formula based on the images collected by the automated acquisition equipment in the maintenance area; When the repair compliance rate exceeds the standard repair rate, the repair acceptance is completed to form a fully automatic closed-loop management.

[0059] In the present invention, after completing the on-site maintenance work according to the automatically distributed task notice, the corresponding repair rate standard is calculated through a formula based on the type of disease and its classification, and the completion degree of the repair project is automatically evaluated in combination with the repair progress data and the preset repair rate standard.

[0060] Assumptions represents the standard repair rate, Indicates the degree of impact of the disease on driving safety (quantified as 0-100), Indicates the urgency of the repair of the defect (quantified as 0-100), and the calculation formula of the repair rate can be expressed as follows.

[0061] .

[0062] Among them, m and n are weight coefficients, which can be adjusted according to actual conditions. Among them, m and n are weight coefficients of the degree of impact on driving safety and the urgency of defect repair determined based on historical experience, and the weight coefficients are selected between 0 and 1.

[0063] Assume that R1 is the current repair rate, R0 is the previous repair rate, and the acceptance formula is as follows.

[0064] .

[0065] refer to Figure 2 and Figure 3 , calculate and compare the completion status of this repair according to the above acceptance formula. When the completion rate reaches the standard, the system automatically changes the document status to "passed acceptance".

[0066] Check the acceptance status on the task notification list page. The initial status is "Not Accepted". When the automated inspection equipment uploads the "Acceptance Inspection" record, the system automatically corresponds to the same route, driving direction, lane position, kilometer section and other information. This standard repair rate According to the acceptance formula , the system automatically changes the document status to "passed acceptance".

[0067] In the present invention, a fully automatic closed management system of "maintenance inspection - disease record - task notification - acceptance management" is constructed, and an innovative integrated detection and maintenance mode is adopted. After a disease is found during the maintenance inspection process, a disease record is automatically generated according to the principle of automatic classification and treatment of the disease; the disease information in the disease record is summarized according to single-kilometer sections, and a task notification is automatically generated for each kilometer of disease and distributed to the maintenance work area; each task notification includes the location and specific conditions of all diseases within each kilometer; after the on-site construction is completed, the highway repair completion rate is calculated according to the formula, and the acceptance status of the task notification in the system is dynamically adjusted by comparing the corresponding limit values, thus completing the fully automatic closed management system of "maintenance inspection - disease record - task notification - acceptance management".

[0068] Based on a closed-loop control method for automated daily maintenance management of highways provided by the present invention, the location and number of defects are discovered through inspection of highways, a defect log is generated, on-site repairs are carried out on the defective areas, and acceptance inspections are conducted on the repair results. This method deeply integrates technical resources, optimizes the operation process, and establishes an efficient cycle from defect discovery to processing feedback, providing a more reliable and efficient guiding basis for highway maintenance management, thereby improving the intelligence and automation level of highway maintenance work.

[0073] The disease is classified according to the disease location and the number of diseases. If the degree of damage caused by the disease exceeds the preset dynamic threshold value based on the classification result, the corresponding disease situation is recorded in the disease record, including: Classify the diseases according to the disease locations and the number of diseases, and determine the average damaged length and damaged area of ​​the diseases based on the classification results; When the average damaged length or damaged area of ​​the disease exceeds the preset dynamic threshold, the corresponding disease situation will be recorded in the disease record; The dynamic threshold is dynamically adjusted according to the changes in the damaged length and damaged area.

[0074] Based on the results of on-site maintenance, acceptance inspections are carried out through automated data collection equipment to calculate the repair compliance rate. If the repair compliance rate exceeds the standard repair rate, the repair acceptance is completed, including: After completing on-site maintenance, based on the results of on-site maintenance, images are collected in the maintenance area through automated acquisition equipment for acceptance inspection; The repair compliance rate is calculated using a preset formula based on the images collected by the automated acquisition equipment in the maintenance area; When the repair compliance rate exceeds the standard repair rate, the repair acceptance is completed.

[0075] In the present invention, after completing the on-site maintenance work according to the automatically distributed task notice, the corresponding repair rate standard is calculated through a formula based on the type of disease and its classification, and the completion degree of the repair project is automatically evaluated in combination with the repair progress data and the preset repair rate standard.

When the automated inspection equipment uploads the "Acceptance Inspection" record, the system automatically corresponds to the same route, driving direction, lane position, kilometer section and other information.
