Description

Technical Field

[0001] The invention belongs to the technical field of traffic engineering, and in particular is a method for collecting status information of traffic infrastructure. Background Art

[0002] In recent years, traffic problems have become one of the major issues that have attracted widespread social attention and restricted the sustainable development of my country's economy, seriously affecting people's work and life. In the current context where the construction of road traffic and other infrastructure lags behind the growth rate of motor vehicle ownership, how to effectively utilize existing road resources has positive significance for alleviating the current traffic congestion to a certain extent.

[0003] The collection equipment used in the existing methods for collecting information on the status of transportation infrastructure mostly consumes electricity directly or converts light energy and electricity through solar panels. However, the collection equipment that directly consumes electricity has a large demand for electricity, and the storage of electricity through solar panels is more dependent on sunlight. When the converted electricity is insufficient, there will still be a large demand for electricity. Therefore, it is necessary to propose a method for collecting information on the status of transportation infrastructure. Summary of the invention

[0004] In order to solve the problem of large demand for electric energy by the above-mentioned existing collection equipment, the purpose of the present invention is to propose a method for facilitating the collection of traffic infrastructure status information, by charging the power supply through the charge generated when the vehicle presses the piezoelectric ceramic, thereby reducing the overall demand for electric energy of the device.

[0005] In order to achieve the above object, the technical solution of the present invention is as follows: a method for facilitating the collection of traffic infrastructure status information, comprising the following steps:

[0006] Step 1, data collection preparation: bury the piezoelectric component used to charge the power supply in the detection section, and fix the positive and negative poles of the power supply line to the top and bottom of the piezoelectric component respectively; connect the data collection device to the power supply and install it on one side of the detection section; the data collection device signal is connected to the controller, and the controller will analyze and process the information collected by the data collection device;

[0007] Step 2, information collection: the collection device collects road image information, current environmental temperature and humidity information, vehicle pressure information on the road surface, and road vibration information, and sends the collection results to the controller;

[0008] Step 3, information processing: The controller conducts a comprehensive analysis on the collected road surface image information, temperature and humidity information, pressure information and vibration information, and obtains different analysis results according to different road surface damage conditions. When the analysis results are obtained, the analysis process and analysis results are generated into an analysis report;

[0009] Step 4: Information upload: The controller uploads the analysis results to the cloud and sends an analysis report to the maintenance personnel to inform them of the specific conditions of the inspection section.

[0010] Step 5: Plan execution: Maintenance personnel go to the inspection section for on-site inspection, upload the inspection results to the cloud, and formulate and implement relevant plans.

[0011] The principle of the basic solution is: when the vehicle presses on the road surface, the piezoelectric ceramics buried in the detection section will be pressed by the road surface, causing the piezoelectric ceramics to generate electric charge; the charge generated by the piezoelectric ceramics will form an electric current through the metal plate and the power line during the movement, charging the power supply, and the power supply will supply power to the entire device. At this time, the acquisition equipment will collect road image information, environmental temperature and humidity information, vehicle pressure information on the road surface and road vibration information, and send the collection results to the controller, which will conduct a comprehensive analysis and obtain the corresponding analysis results, and generate an analysis report for the analysis process.

[0012] After the analysis is completed, the controller will send the analysis results to the cloud and send the analysis report to the construction personnel to inform them of the specific conditions of the test section. After receiving the report, the construction personnel will go to the test section for verification, upload the verification results to the cloud, and formulate and implement corresponding plans based on the different road damage conditions. The plans here include but are not limited to road maintenance plans and collection equipment maintenance or replacement plans.

[0013] The beneficial effects of the basic scheme are: 1. This method can charge the power supply through the charge generated when the vehicle compresses the piezoelectric ceramic, thereby reducing the overall demand for electricity of the device. Compared with the collection equipment using solar panels, this collection equipment can use the traffic flow to charge the power supply, which is more stable than the dependence of solar energy on sunlight.

[0014] 2. The analysis process and analysis results are generated into an analysis report, so that the analysis process is clear at a glance. When the collection equipment fails, the construction personnel can quickly identify the fault problem through the analysis report and then formulate a solution; when the collection equipment does not fail, the analysis report can provide the construction personnel with detailed analysis data for reference, which can assist the construction personnel in formulating corresponding road maintenance plans to a certain extent.

[0015] 3. Construction personnel go to the site for a second inspection, which enables them to further understand the specific conditions of the inspection section and judge the current operation status of the collection equipment. When there is a large gap between the analysis results obtained by the controller and the inspection results of the construction personnel, the construction personnel can promptly inspect, repair or replace the collection equipment, thereby reducing the situation where road information cannot be collected due to damage to the collection equipment.

[0016] 4. The design of uploading the analysis and verification results to the cloud enables construction personnel to monitor the specific conditions of the inspection road in real time through changes in cloud data, thereby improving the reliability of the collection method.

[0017] Furthermore, in step one, the piezoelectric component includes a piezoelectric ceramic, and a metal plate and a cement plate are provided on the top and bottom of the piezoelectric ceramic. The metal plate is located on the side close to the collection device, and the cement plate is located on the side away from the collection device.

[0018] The principle and beneficial effect of the basic scheme are: piezoelectric ceramics will generate electric charge when they are compressed, and the electric charge will be introduced into the power supply by the power line under the conductive effect of the metal plate, thereby charging the power supply. The design of piezoelectric ceramics and metal plates enables the electric charge generated by piezoelectric ceramics to charge the power supply when the vehicle passes over the detection section, thereby reducing the need for electric energy and playing a certain positive role in protecting the environment and saving energy.

[0019] Furthermore, in step one, a nickel layer is plated on the surface of the metal plate, and an anti-rust paint is applied on the side of the surface of the nickel layer away from the piezoelectric ceramic.

[0020] The principle and beneficial effect of the basic solution are: the nickel layer and the anti-rust paint can delay the rusting of the metal plate to a certain extent, thereby increasing the service life of the metal plate and reducing the overall consumable loss of the device.

[0021] Further, in step one, the collection equipment includes a vertical support rod, the bottom of the vertical support rod is fixedly connected to the ground, the side wall of the vertical support rod is fixedly connected to a detection box, the outer wall of the detection box is fixedly connected to an LED screen, the LED screen is electrically connected to a power supply, the power supply is located below the detection box, and a plurality of partitions are fixedly connected to the inner wall of the detection box, and the partitions divide the interior of the detection box into a temperature and humidity detection chamber, a pressure detection chamber, and a vibration detection chamber; a temperature and humidity sensor is fixedly connected in the temperature and humidity detection chamber, a pressure sensor is fixedly connected in the pressure detection chamber, and a radar is fixedly connected in the vibration detection chamber; a horizontal support rod is fixedly connected to the top of the vertical support rod, and an infrared camera is fixedly connected to the surface of the horizontal support rod.

[0022] The principle and beneficial effects of the basic solution are: the infrared camera will collect road image information; the temperature and humidity sensor will collect the temperature and humidity information of the current environment; the radar will collect the vibration information of the ground; the power supply will power the LED screen;

[0023] The design of the infrared camera on the surface of the horizontal support rod enables the infrared camera to shoot the inspection section from above the inspection section, which can more accurately collect road image information compared to shooting the road surface from both sides of the inspection section; the detection box can effectively protect the temperature and humidity sensors, pressure sensors and radars inside the detection box, thereby reducing the possibility of damage to the temperature and humidity sensors, pressure sensors and radars.

[0024] Furthermore, in step one, an alarm is fixedly connected to the inner wall of the detection box, and the alarm is connected to the controller signal.

[0025] The principle and beneficial effect of the basic solution are: when the detection box is damaged, the alarm device will send an alarm input signal to the controller, at which time the construction personnel can know through the controller that the detection box is damaged, and then the construction personnel can go to repair the detection box.

[0026] Furthermore, in step 2, after the acquisition device completes the acquisition of the temperature and humidity information of the current environment and the pressure information exerted by the car on the road surface, the collected temperature and humidity information and the pressure information exerted by the road surface will be displayed in real time through the LED screen.

[0027] The principle and beneficial effect of the basic scheme is: the temperature and humidity information and the pressure information on the road surface are displayed in real time through the LED screen, so that the construction workers and drivers can intuitively understand the current temperature and humidity information and the pressure information on the road surface, so that the construction workers and drivers can take corresponding measures. For example: when the humidity is too high and the road surface is slippery, the driver can replace the vehicle with a tire with stronger grip, and the construction workers can warn the driver to remind the driver to drive carefully.

[0028] Furthermore, in step three, the controller first discards a maximum value and a minimum value before performing analysis.

[0029] The principle and beneficial effect of the basic solution are: the operation of discarding the maximum and minimum values ​​can effectively reduce the impact of data generated by errors on the overall analysis results, thereby improving the accuracy of the analysis results.

[0030] Furthermore, in step three, the controller first grays the image information using a grayscale formula, and then sharpens the image using an energy gradient formula. The grayscale formula and energy gradient formula are as follows:

[0031] Grayscale formula:

[0032]

[0033] Among them, Gray represents the gray value, R represents the red value of the pixel, G represents the green value of the pixel, and B represents the blue value of the pixel;

[0034] Energy gradient formula:

[0035] D(f)=∑ x Σ y {[f(x+1,y)-f(x,y)] 2 +[f(x,y+1)-f(x,y)] 2}

[0036] Among them, the lower left corner of the image is taken as the origin, and (x, y) represents the location coordinates of the pixel.

[0037] The principle and beneficial effects of the basic scheme are as follows: grayscale processing of images can reduce the image storage space occupied, thereby reducing the image processing and storage costs. At the same time, since the grayscale processed image only contains single-channel information, the grayscale image processing speed is faster than the color image, making it easier for the visual algorithm to recognize and process, facilitating subsequent sharpening operations.

[0038] The energy gradient formula can intuitively reflect the changing trends and characteristics of the physical processes inside an object. The larger the energy gradient function, the more drastic the grayscale changes of the image in the spatial domain. This can intuitively judge the clarity of the image and produce a sharpening effect on the image.

[0039] Further, in step three, when the crack width in the image information analyzed by the controller is less than 3mm, the crack depth is between 10-15mm, and the vehicle is traveling on the detection road with a shaking amplitude of less than 10°, the road damage is determined to be slightly damaged; when the crack width is between 3-5mm, the crack depth is between 15-20mm, and the vehicle is traveling on the detection road with a shaking amplitude of 10-15°, the road damage is determined to be moderately damaged; when the crack width is greater than 5mm, the crack depth is greater than 20mm, and the vehicle is traveling on the detection road with a shaking amplitude of greater than 15°, the road damage is determined to be severely damaged.

[0040] The principles and beneficial effects of the basic plan are: to classify the road damage conditions. After clarifying the road damage conditions, when multiple roads need to be repaired, construction workers can consider the priority of road repair, such as repairing roads with more serious damage first, and then repairing roads with less damage, thereby optimizing the allocation of resources; according to the different damage conditions of the roads, construction workers will also make corresponding adjustments to the road repair strategy and repair cost. When repairing roads with more serious damage, the repair strategy that construction workers need to adopt will be relatively complex, and the repair cost will also be higher.

[0041] Furthermore, in step three and step four, after completing the comprehensive analysis of various information, the controller gives a prediction result based on the analysis result, and sends the prediction result to the cloud synchronously, and the prediction result is synchronously presented in the analysis report.

[0042] The principle and beneficial effect of the basic solution are as follows: when the humidity sensed by the temperature and humidity sensor gradually increases over time, the controller will determine the possibility of rain in the near future. If the judgment result is that it will rain, it will send corresponding suggestions to the construction personnel based on the road damage so that the construction personnel can take corresponding measures;

[0043] When the road is slightly damaged and does not affect the passage of vehicles, the controller will not send suggestions to the construction workers; when the road is moderately damaged and there will be some bumps during vehicle driving, the controller will send warning suggestions to the construction workers, and the construction workers can then add speed limit warnings at the road entrance and midway; when the road is severely damaged and vehicles have difficulty traveling, the controller will send closure suggestions to the construction workers, and the construction workers can then close the road and carry out road repair work.

[0051] Step 2, information collection: the infrared camera 1021 collects road surface image information by photographing the road surface, and sends the road surface image information to the controller; the temperature and humidity sensor collects the temperature and humidity information of the current environment according to the sensed temperature and humidity information, and sends the temperature and humidity information to the controller; the pressure sensor collects the pressure information of the car on the road surface according to the change of road surface pressure, and sends the pressure information to the controller; the radar collects the vibration information of the road surface according to the vibration of the monitored road surface, and sends the vibration information to the controller; the temperature and humidity sensor and the pressure sensor display the collected temperature and humidity information and the pressure information of the road surface in real time through the LED screen 1012;

[0052] Step 3, information processing: The controller performs a comprehensive analysis on the collected road image information, temperature and humidity information, pressure information and vibration information. Before the analysis, the controller first discards a maximum value and a minimum value;

[0053] When processing road image information, the controller first uses the grayscale formula to grayscale the image information, and then sharpens the image using the energy gradient formula. The grayscale formula and energy gradient formula are as follows:

[0054] Grayscale formula:

[0055]

[0056] Among them, Gray represents the gray value, R represents the red value of the pixel, G represents the green value of the pixel, and B represents the blue value of the pixel;

[0059] Among them, the lower left corner of the image is taken as the origin, and (x, y) represents the location coordinates of the pixel point;

[0060] The controller obtains analysis results according to the damage of the road surface, and generates an analysis report for the analysis process and analysis results;

[0061] After the controller performs image clarification processing, if the analysis shows that the crack width in the image information is less than 3mm, the crack depth is between 10-15mm, and the vehicle is traveling on the detection road with a shaking amplitude of less than 10°, the road damage is determined to be slightly damaged; if the crack width is between 3-5mm, the crack depth is between 15-20mm, and the vehicle is traveling on the detection road with a shaking amplitude of 10-15°, the road damage is determined to be moderately damaged; if the crack width is greater than 5mm, the crack depth is greater than 20mm, and the vehicle is traveling on the detection road with a shaking amplitude of greater than 15°, the road damage is determined to be severely damaged;

The prediction results will be presented synchronously in the analysis report;

[0063] Step 5: Plan execution: Maintenance personnel go to the inspection section for on-site inspection, upload the inspection results to the cloud, and formulate and implement relevant plans.

[0064] The specific implementation process is as follows: the construction personnel first bury the piezoelectric ceramics 201, cement board 202 and metal plate 203 in the detection section, and weld the positive and negative poles of the power cord of the power supply 1013 to the metal plate 203, and install the collection equipment 1 on one side of the detection section to complete the preparation for collecting information.

[0065] When a vehicle passes through the detection section, the vehicle will press the road surface, and then the road surface will press the piezoelectric ceramic 201. After being pressed, the piezoelectric ceramic 201 will generate electric charge, and at this time, the electric charge will generate current through the metal plate 203 and the power line during the movement, charging the power supply 1013, and then the power supply 1013 will power the acquisition device 1 as a whole.
