Description

Technical Field

[0001] This invention relates to the field of road construction technology, and in particular to a method and apparatus for the coordinated detection of the spread rate of synchronous chip seal layer. Background Technology

[0002] Synchronous chip seal is a road construction and maintenance technique that involves simultaneously spreading crushed stone and binder materials (modified asphalt or modified emulsified asphalt) onto the road surface using a synchronous chip seal vehicle, and then compacting it through natural vehicle traffic to form a single-layer asphalt-crushed stone functional layer. In the construction of new roads, synchronous chip seal acts as a bonding functional layer, a rigid-flexible transition layer, a waterproof layer, and a stress-absorbing layer between the asphalt pavement surface layer and the water-stabilized layer. Its construction quality affects the overall stress distribution of the pavement and the shear resistance of the asphalt surface layer.

[0003] The aggregate spreading rate is one of the key quality control indicators for synchronous aggregate seal pavement construction. Traditional testing methods typically involve placing or fixing a sample pan of known area on the working surface. After the emulsified asphalt and aggregate are spread, the mass of the aggregate in the sample pan is obtained through extraction or immersion in trichloroethylene, and the amount of aggregate spread is calculated. The problem with this method is its cumbersome nature, requiring a certain testing cycle, and inability to provide timely detection and correction, which is detrimental to process control of construction quality. Therefore, providing a more efficient testing method for the aggregate spreading rate is crucial. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a collaborative detection method and device for the crushed stone spreading rate of synchronous crushed stone sealing layer, which can improve the detection efficiency of crushed stone spreading rate.

[0005] To address the aforementioned technical problems, the first aspect of this invention discloses a collaborative detection method for the spread rate of synchronous crushed stone sealing layer, the method comprising: The detection program on the construction party's mobile device sends the gravel spread rate detection request to the cloud server; the gravel spread rate detection request includes the road number corresponding to the synchronous gravel seal layer to be detected. When the cloud server receives a request from the construction party to detect the stone spreading rate, it prompts the construction party to place a reference frame on the synchronous stone sealing layer corresponding to the spreading rate detection request; the reference frame is a hollow frame, and the synchronous stone sealing layer inside the reference frame is used for stone spreading rate detection. After the construction team places the reference frame on the synchronous crushed stone seal layer, the detection software uses the camera of the mobile device to take a picture of the reference frame to obtain the initial seal layer image. The target sealing image is obtained by preprocessing the initial sealing image using detection software. The target cover image is uploaded to a cloud server based on the detection software. The target sealing image is detected on the cloud server based on the gravel spreading rate detection model to obtain the gravel spreading rate detection result. The gravel spreading rate detection result is stored on the cloud server and fed back to the mobile device.

[0026] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0027] This invention discloses a collaborative detection method and apparatus for the spread rate of synchronous chip seal layer. Implementing the method described in the embodiments of this invention enables the synchronous chip seal layer to be photographed and preprocessed based on a detection program on a mobile device, and then detected using a model on a cloud server to obtain the chip spread rate detection result, which is beneficial to improving the detection efficiency of the chip spread rate. Detailed descriptions follow.

[0028] Example 1 Please see Figure 1 , Figure 1 This is a schematic flowchart of a collaborative detection method for the spread rate of synchronous crushed stone sealing layer disclosed in an embodiment of the present invention. Wherein, Figure 1 The described method can be applied to any scenario where the chip spread rate of synchronous chip seal is detected, and the embodiments of the present invention are not limited thereto. Figure 1 As shown, the collaborative detection method for the crushed stone spreading rate of the synchronous crushed stone seal layer includes the following operations: 101. The detection program on the construction party's mobile device sends the crushed stone spreading rate detection request to the cloud server; In this embodiment of the invention, the request for detecting the crushed stone spreading rate includes the road number corresponding to the synchronous crushed stone seal layer to be detected; 102. When the cloud server receives a request from the construction party to detect the crushed stone spreading rate, it prompts the construction party to place the reference frame on the synchronous crushed stone sealing layer corresponding to the spreading rate detection request. In this embodiment of the invention, the reference frame is a hollow frame, and the synchronous crushed stone sealing layer inside the reference frame is used for crushed stone spreading rate detection; 103. After the construction team places the reference frame on the synchronous crushed stone seal layer, the detection software calls the camera of the mobile device to take a picture of the reference frame to obtain the initial seal layer image; In this embodiment of the invention, the reference frame can be any shape such as a rectangular frame or a circular frame, and this embodiment of the invention does not limit it; for example, if the reference frame is a rectangular frame, it can be made of aluminum alloy to reduce the risk of deformation, and its inner side dimensions can be 400mm*600mm. 104. Based on the detection software, the initial sealing layer image is preprocessed to obtain the target sealing layer image; 105. The target cover image is uploaded to the cloud server based on the detection software; In this embodiment of the invention, before uploading the target sealing image to the cloud server in step 105, the construction party can first confirm the image quality, and upload it only after confirming that there are no errors. 106. The target sealing image is detected on the cloud server based on the gravel spreading rate detection model to obtain the gravel spreading rate detection result. The gravel spreading rate detection result is stored on the cloud server and fed back to the mobile device.

[0029] In this embodiment of the invention, the gravel spread rate detection model can be trained based on the ConvNextV2 model or on other image detection model frameworks; this embodiment of the invention does not impose any limitations. The synchronous gravel seal images required for training the gravel spread rate detection model have different gravel spread rates. Under conditions of smooth network connectivity and normal operation of the cloud server, the processing time of step 106 should not exceed 15 seconds. Depending on the functional layer, the gravel spread rate of the synchronous gravel seal generally requires a gravel coverage rate of 60-90% on the hot asphalt.

[0030] As can be seen, the method described in this invention can send a gravel spreading rate detection request to a cloud server based on the detection program on the construction party's mobile device, prompting the construction party to place a reference frame on the synchronous gravel sealing layer, take a picture of the reference frame to obtain an initial sealing layer image, perform image preprocessing on the initial sealing layer image based on the detection software to obtain a target sealing layer image and upload it to the cloud server; the cloud server detects the target sealing layer image based on the gravel spreading rate detection model to obtain the gravel spreading rate detection result, stores the result on the cloud server and feeds it back to the mobile device, which helps to improve the detection efficiency of gravel spreading rate.

[0031] In an optional embodiment, step 102 above, where the cloud server receives a request from the construction party to detect the stone spreading rate, prompts the construction party to place a reference frame on the synchronous stone sealing layer corresponding to the spreading rate detection request. This may include: When the cloud server receives a request from the construction party to detect the rate of crushed stone spreading, it uses the detection program to call the positioning program on the mobile device to obtain the location of the mobile device. Determine whether the location of the mobile device matches the road number of the synchronous gravel seal layer corresponding to the gravel spread rate detection request, and obtain the road matching judgment result; When the road matching judgment result indicates that the location of the mobile device matches the road number of the synchronous crushed stone seal corresponding to the crushed stone spreading rate detection request, it is determined whether the construction party matches the road number of the synchronous crushed stone seal corresponding to the crushed stone spreading rate detection request, and the construction party matching result is obtained. When the matching result of the construction party is used to indicate that the construction party matches the road number of the synchronous chip seal corresponding to the chip spread rate detection request, the construction party is prompted to place the reference box on the synchronous chip seal corresponding to the spread rate detection request.

[0032] As can be seen, this optional embodiment can obtain the location of the mobile device by calling the positioning program on the mobile device based on the detection program, and determine whether the location of the mobile device matches the road number of the synchronous crushed stone seal corresponding to the crushed stone spreading rate detection request. If they match, it determines whether the construction party matches the road number of the synchronous crushed stone seal corresponding to the crushed stone spreading rate detection request. If they still match, it prompts the construction party to place the reference box on the synchronous crushed stone seal corresponding to the spreading rate detection request. This helps to reduce the possibility that the crushed stone spreading rate detection request does not correspond to the synchronous crushed stone seal that needs to be detected, and at the same time reduces the possibility that the construction party will detect the synchronous crushed stone seal that is not under its construction, thereby reducing the processing burden of the crushed stone spreading rate detection model on the cloud server.

[0033] In another optional embodiment, the image preprocessing of the initial sealing image based on the detection software in step 104 above to obtain the target sealing image may include: The first sealing image is obtained by identifying the inner edge of the reference box in the initial sealing image using detection software and cropping the initial sealing image with the inner edge of the reference box as the boundary. The first cover image is converted into a standard-resolution second cover image with a rectangular shape based on the image perspective transformation matrix algorithm; The second cover image is converted to grayscale to obtain the target cover image after image preprocessing.

[0034] As can be seen, this optional embodiment can identify and crop the inner edge of the reference box in the initial sealing image, convert it into a standard resolution image of a rectangular shape, and then perform grayscale conversion to obtain the target sealing image. This helps to improve the accuracy of the target sealing image, thereby improving the detection accuracy and efficiency of the gravel spreading rate.

[0035] In another optional embodiment, step 103 above, which involves the detection software calling the mobile device's camera to capture an image of the reference frame to obtain an initial cover image, may include: The detection program calls the weather forecast and location programs on the mobile device to obtain the real-time weather conditions corresponding to the location of the mobile device. If the real-time weather conditions corresponding to the location of the mobile device are sunny, the construction team is prompted to use an umbrella to shield the reference frame. After the construction team uses an umbrella to cover the reference frame, the detection software uses the camera of a mobile device to take a picture of the reference frame, thus obtaining an initial sealing layer image.

[0036] In this optional embodiment, the shooting focal length can be between 23mm and 28mm, and the distance from the gravel seal ground is about 1m-1.5m; using an umbrella to shield the reference frame can avoid direct sunlight and improve the shooting effect of the initial seal image.

[0037] As can be seen, this optional embodiment can call the weather forecast program and the positioning program on the mobile device based on the detection program to obtain the real-time weather conditions corresponding to the location of the mobile device; if the real-time weather conditions are sunny, it prompts the construction party to use an umbrella to shield the reference frame, and further takes pictures of the reference frame to obtain the initial sealing layer image, which helps to reduce the influence of sunlight on the initial sealing layer image, thereby improving the detection accuracy and efficiency of the gravel spreading rate.

[0038] In yet another optional embodiment, the method may further include: Determine whether the crushed stone spreading rate test result meets the preset crushed stone spreading rate threshold, and obtain the crushed stone spreading rate judgment result; When the crushed stone spreading rate judgment result is used to indicate that the crushed stone spreading rate detection result does not meet the crushed stone spreading rate threshold, the synchronous crushed stone seal corresponding to the crushed stone spreading rate judgment result is determined, and the target synchronous crushed stone seal vehicle for the construction of the synchronous crushed stone seal is determined. Identify all target synchronous chip seal layers constructed by the target synchronous chip seal layer vehicle; obtain the chip spreading rate of each target synchronous chip seal layer, and calculate the proportion of qualified synchronous chip seal layers to all target synchronous chip seal layers; wherein, qualified synchronous chip seal layers are target synchronous chip seal layers whose chip spreading rate reaches the chip spreading rate threshold. Determine whether the compliance rate has reached the preset threshold and obtain the threshold judgment result. When the result of the compliance rate threshold judgment is used to indicate that the compliance rate has reached the threshold, the target synchronous chip seal vehicle is identified as a synchronous chip seal vehicle to be re-inspected.

[0039] In this optional embodiment, it is understood that when the crushed stone spreading rate judgment result is used to indicate that the crushed stone spreading rate detection result does not meet the crushed stone spreading rate threshold, it can be determined whether the problem of the crushed stone spreading rate judgment result not meeting the crushed stone spreading rate threshold is due to the problem of the synchronous crushed stone sealing vehicle itself, by identifying the synchronous crushed stone sealing vehicle that carried out the construction of this section of synchronous crushed stone sealing, and further identifying the crushed stone spreading rate judgment result of other road sections constructed by the synchronous crushed stone sealing vehicle.

[0040] As can be seen, this optional embodiment can determine whether the crushed stone spreading rate test result meets the preset crushed stone spreading rate threshold. If it does not meet the threshold, it determines the synchronous crushed stone seal corresponding to the crushed stone spreading rate judgment result, and determines the target synchronous crushed stone seal vehicle used for the construction of the synchronous crushed stone seal. It also determines all target synchronous crushed stone seals constructed by the target synchronous crushed stone seal vehicle, obtains the crushed stone spreading rate of each target synchronous crushed stone seal, calculates the compliance ratio of the compliant synchronous crushed stone seal to all target synchronous crushed stone seals, and determines whether the compliance ratio reaches the ratio threshold. If the ratio threshold is reached, the target synchronous crushed stone seal vehicle is identified as a synchronous crushed stone seal vehicle to be re-inspected. This helps to improve the accuracy of determining the synchronous crushed stone seal vehicle to be re-inspected based on the crushed stone spreading rate test result, thereby reducing the possibility that a problematic synchronous crushed stone seal vehicle will continue to complete synchronous crushed stone seal construction that does not meet the crushed stone spreading rate threshold.

[0041] In yet another optional embodiment, the method may further include: Acquire several first seal images of the synchronous gravel sealing layer corresponding to the gravel spread rate detection request; the first seal images are taken by traffic participants, including vehicle drivers and passengers as well as pedestrians; For each first sealing layer image, the cloud server detects the first sealing layer image based on the gravel spreading rate detection model to obtain the first gravel spreading rate detection result corresponding to the first sealing layer image; Based on the first gravel spread rate detection results corresponding to all first seal layer images, determine the reference gravel spread rate detection results for the synchronous gravel seal layer corresponding to the gravel spread rate detection request; Obtain the gravel spread rate detection result of the synchronous gravel sealing layer corresponding to the gravel spread rate detection request on the cloud server; Determine whether the difference between the reference crushed stone spreading rate test result and the crushed stone spreading rate test result exceeds the preset crushed stone spreading rate error threshold. If it does, mark the crushed stone spreading rate test result corresponding to the crushed stone spreading rate test request as pending re-inspection.

[0042] In this optional embodiment, it is understood that the gravel spreading rate detection model can be made available to traffic participants. Based on the reference gravel spreading rate detection results corresponding to the seal layer images taken by different traffic participants, it can be determined whether the gravel spreading rate detection results obtained by the construction party need to be re-inspected. This can make full use of public resources and reduce the possibility of problems with the gravel spreading rate.

[0043] As can be seen, this optional embodiment can acquire several first seal images from traffic participants, and detect the first seal images to obtain a first gravel spread rate detection result. Based on the first gravel spread rate detection results corresponding to all first seal images, a reference gravel spread rate detection result is determined. The gravel spread rate detection result of the gravel spread rate detection request is obtained. It is determined whether the difference between the reference gravel spread rate detection result and the gravel spread rate detection result exceeds a preset gravel spread rate error threshold. If it exceeds the threshold, the gravel spread rate detection result corresponding to the gravel spread rate detection request is marked as pending re-inspection. This helps to improve the accuracy of the judgment of the gravel spread rate detection result re-inspection based on the reference gravel spread rate detection result obtained from the images taken by traffic participants, thereby improving the accuracy of determining the gravel spread rate of the synchronous gravel seal.

[0044] In yet another alternative embodiment, after determining the target synchronized chip seal vehicle for the synchronized chip seal construction in the above steps, the method may further include: Determine the driving speed and spreading parameters of the target synchronous chip seal vehicle, and adjust the driving speed and / or spreading parameters of the target synchronous chip seal vehicle so that the subsequent chip spreading rate test results meet the chip spreading rate threshold.

[0045] As can be seen, this optional embodiment can determine the driving speed and spreading parameters of the target synchronous chip seal vehicle. Adjusting the driving speed and / or spreading parameters of the target synchronous chip seal vehicle can help reduce the possibility that the synchronous chip seal subsequent construction by the synchronous chip seal vehicle will meet the non-chip spread rate threshold.

[0046] Example 2 Please see Figure 2 , Figure 2 This is a schematic diagram of the structure of a collaborative detection device for the simultaneous crushed stone sealing layer crushed stone spreading rate disclosed in an embodiment of the present invention. Wherein, Figure 2 The described device can be applied to any scenario involving the detection of the chip spread rate in synchronous chip seal layers, and the embodiments of the present invention are not limited thereto. Figure 2 As shown, the collaborative detection device for the simultaneous crushed stone cover crushing rate can include: The sending module 201 is used to send a gravel spreading rate detection request to the cloud server based on the detection program on the construction party's mobile device; the gravel spreading rate detection request includes the road number corresponding to the synchronous gravel seal layer to be detected; The prompt module 202 is used to prompt the construction party to place the reference frame on the synchronous crushed stone sealing layer corresponding to the crushed stone spreading rate detection request when the cloud server receives the crushed stone spreading rate detection request from the construction party; the reference frame is a hollow frame, and the synchronous crushed stone sealing layer inside the reference frame is used for crushed stone spreading rate detection. The shooting module 203 is used to capture the initial seal image by calling the camera of the mobile device based on the detection software after the construction party places the reference frame on the synchronous crushed stone seal layer. Processing module 204 is used to perform image preprocessing on the initial sealing image based on the detection software to obtain the target sealing image; Upload module 205 is used to upload the target cover image to the cloud server based on the detection software; The detection module 206 is used to detect the target sealing image on the cloud server based on the gravel spreading rate detection model, obtain the gravel spreading rate detection result, store the gravel spreading rate detection result on the cloud server and feed it back to the mobile device.

[0047] As can be seen, the device described in this invention can send a request for detecting the crushed stone spreading rate to a cloud server based on the detection program on the construction party's mobile device, prompting the construction party to place a reference frame on the synchronous crushed stone sealing layer, take a picture of the reference frame to obtain an initial sealing layer image, perform image preprocessing on the initial sealing layer image based on the detection software to obtain a target sealing layer image and upload it to the cloud server; the cloud server detects the target sealing layer image based on the crushed stone spreading rate detection model to obtain the crushed stone spreading rate detection result, stores the result on the cloud server and feeds it back to the mobile device, which helps to improve the detection efficiency of the crushed stone spreading rate.

[0048] In an optional embodiment, when the cloud server receives a request from the construction party to detect the stone spreading rate, the prompting module 202 prompts the construction party to place a reference frame on the synchronous stone sealing layer corresponding to the spreading rate detection request. Specific methods may include: When the cloud server receives a request from the construction party to detect the rate of crushed stone spreading, it uses the detection program to call the positioning program on the mobile device to obtain the location of the mobile device. Determine whether the location of the mobile device matches the road number of the synchronous gravel seal layer corresponding to the gravel spread rate detection request, and obtain the road matching judgment result; When the road matching judgment result indicates that the location of the mobile device matches the road number of the synchronous crushed stone seal corresponding to the crushed stone spreading rate detection request, it is determined whether the construction party matches the road number of the synchronous crushed stone seal corresponding to the crushed stone spreading rate detection request, and the construction party matching result is obtained. When the matching result of the construction party is used to indicate that the construction party matches the road number of the synchronous chip seal corresponding to the chip spread rate detection request, the construction party is prompted to place the reference box on the synchronous chip seal corresponding to the spread rate detection request.

[0049] As can be seen, this optional embodiment can obtain the location of the mobile device by calling the positioning program on the mobile device based on the detection program, and determine whether the location of the mobile device matches the road number of the synchronous crushed stone seal corresponding to the crushed stone spreading rate detection request. If they match, it determines whether the construction party matches the road number of the synchronous crushed stone seal corresponding to the crushed stone spreading rate detection request. If they still match, it prompts the construction party to place the reference box on the synchronous crushed stone seal corresponding to the spreading rate detection request. This helps to reduce the possibility that the crushed stone spreading rate detection request does not correspond to the synchronous crushed stone seal that needs to be detected, and at the same time reduces the possibility that the construction party will detect the synchronous crushed stone seal that is not under its construction, thereby reducing the processing burden of the crushed stone spreading rate detection model on the cloud server.

[0050] In another optional embodiment, the processing module 204 performs image preprocessing on the initial sealing image based on the detection software to obtain the target sealing image. Specifically, this may include: The first sealing image is obtained by identifying the inner edge of the reference box in the initial sealing image using detection software and cropping the initial sealing image with the inner edge of the reference box as the boundary. The first cover image is converted into a standard-resolution second cover image with a rectangular shape based on the image perspective transformation matrix algorithm; The second cover image is converted to grayscale to obtain the target cover image after image preprocessing.

[0051] As can be seen, this optional embodiment can identify and crop the inner edge of the reference box in the initial sealing image, convert it into a standard resolution image of a rectangular shape, and then perform grayscale conversion to obtain the target sealing image. This helps to improve the accuracy of the target sealing image, thereby improving the detection accuracy and efficiency of the gravel spreading rate.

[0052] In another optional embodiment, the imaging module 203 uses the camera of the mobile device to capture a picture of the reference frame based on the detection software to obtain an initial cover image. Specific methods may include: The detection program calls the weather forecast and location programs on the mobile device to obtain the real-time weather conditions corresponding to the location of the mobile device. If the real-time weather conditions corresponding to the location of the mobile device are sunny, the construction team is prompted to use an umbrella to shield the reference frame. After the construction team uses an umbrella to cover the reference frame, the detection software uses the camera of a mobile device to take a picture of the reference frame, thus obtaining an initial sealing layer image.

[0053] As can be seen, this optional embodiment can call the weather forecast program and the positioning program on the mobile device based on the detection program to obtain the real-time weather conditions corresponding to the location of the mobile device; if the real-time weather conditions are sunny, it prompts the construction party to use an umbrella to shield the reference frame, and further takes pictures of the reference frame to obtain the initial sealing layer image, which helps to reduce the influence of sunlight on the initial sealing layer image, thereby improving the detection accuracy and efficiency of the gravel spreading rate.

[0054] In yet another alternative embodiment, the device can also be used for: Determine whether the crushed stone spreading rate test result meets the preset crushed stone spreading rate threshold, and obtain the crushed stone spreading rate judgment result; When the crushed stone spreading rate judgment result is used to indicate that the crushed stone spreading rate detection result does not meet the crushed stone spreading rate threshold, the synchronous crushed stone seal corresponding to the crushed stone spreading rate judgment result is determined, and the target synchronous crushed stone seal vehicle for the construction of the synchronous crushed stone seal is determined. Identify all target synchronous chip seal layers constructed by the target synchronous chip seal layer vehicle; obtain the chip spreading rate of each target synchronous chip seal layer, and calculate the proportion of qualified synchronous chip seal layers to all target synchronous chip seal layers; wherein, qualified synchronous chip seal layers are target synchronous chip seal layers whose chip spreading rate reaches the chip spreading rate threshold. Determine whether the compliance rate has reached the preset threshold and obtain the threshold judgment result. When the result of the compliance rate threshold judgment is used to indicate that the compliance rate has reached the threshold, the target synchronous chip seal vehicle is identified as a synchronous chip seal vehicle to be re-inspected.

[0055] As can be seen, this optional embodiment can determine whether the crushed stone spreading rate test result meets the preset crushed stone spreading rate threshold. If it does not meet the threshold, it determines the synchronous crushed stone seal corresponding to the crushed stone spreading rate judgment result, and determines the target synchronous crushed stone seal vehicle used for the construction of the synchronous crushed stone seal. It also determines all target synchronous crushed stone seals constructed by the target synchronous crushed stone seal vehicle, obtains the crushed stone spreading rate of each target synchronous crushed stone seal, calculates the compliance ratio of the compliant synchronous crushed stone seal to all target synchronous crushed stone seals, and determines whether the compliance ratio reaches the ratio threshold. If the ratio threshold is reached, the target synchronous crushed stone seal vehicle is identified as a synchronous crushed stone seal vehicle to be re-inspected. This helps to improve the accuracy of determining the synchronous crushed stone seal vehicle to be re-inspected based on the crushed stone spreading rate test result, thereby reducing the possibility that a problematic synchronous crushed stone seal vehicle will continue to complete synchronous crushed stone seal construction that does not meet the crushed stone spreading rate threshold.

[0056] In yet another alternative embodiment, the device can also be used for: Acquire several first seal images of the synchronous gravel sealing layer corresponding to the gravel spread rate detection request; the first seal images are taken by traffic participants, including vehicle drivers and passengers as well as pedestrians; For each first sealing layer image, the cloud server detects the first sealing layer image based on the gravel spreading rate detection model to obtain the first gravel spreading rate detection result corresponding to the first sealing layer image; Based on the first gravel spread rate detection results corresponding to all first seal layer images, determine the reference gravel spread rate detection results for the synchronous gravel seal layer corresponding to the gravel spread rate detection request; Obtain the gravel spread rate detection result of the synchronous gravel sealing layer corresponding to the gravel spread rate detection request on the cloud server; Determine whether the difference between the reference crushed stone spreading rate test result and the crushed stone spreading rate test result exceeds the preset crushed stone spreading rate error threshold. If it does, mark the crushed stone spreading rate test result corresponding to the crushed stone spreading rate test request as pending re-inspection.

[0057] As can be seen, this optional embodiment can acquire several first seal images from traffic participants, and detect the first seal images to obtain a first gravel spread rate detection result. Based on the first gravel spread rate detection results corresponding to all first seal images, a reference gravel spread rate detection result is determined. The gravel spread rate detection result of the gravel spread rate detection request is obtained. It is determined whether the difference between the reference gravel spread rate detection result and the gravel spread rate detection result exceeds a preset gravel spread rate error threshold. If it exceeds the threshold, the gravel spread rate detection result corresponding to the gravel spread rate detection request is marked as pending re-inspection. This helps to improve the accuracy of the judgment of the gravel spread rate detection result re-inspection based on the reference gravel spread rate detection result obtained from the images taken by traffic participants, thereby improving the accuracy of determining the gravel spread rate of the synchronous gravel seal.

[0058] In yet another alternative embodiment, the device can also be used for: After the device identifies the target synchronous chip seal vehicle for the synchronous chip seal construction, it determines the driving speed and spreading parameters of the target synchronous chip seal vehicle, and adjusts the driving speed and / or spreading parameters of the target synchronous chip seal vehicle so that the subsequent chip spreading rate test results meet the chip spreading rate threshold.

[0059] As can be seen, this optional embodiment can determine the driving speed and spreading parameters of the target synchronous chip seal vehicle. Adjusting the driving speed and / or spreading parameters of the target synchronous chip seal vehicle can help reduce the possibility that the synchronous chip seal subsequent construction by the synchronous chip seal vehicle will meet the non-chip spread rate threshold.
