Detailed Description
Specific embodiments of the present invention will be described in detail below with reference to fig. 1-5, but it should be understood that the scope of the present invention is not limited by the specific embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Example 1:
as shown in fig. 1, 4 and 5, the intelligent highway breakage inspection device provided by the invention comprises a vehicle body 101, and further comprises: the road surface crack detection mechanism comprises a roller 103 and a plurality of depth detection probes 104, wherein the roller 103 and a bearing are connected to the front of the vehicle body 101, a plurality of groups of first through holes 102 are formed in the roller 103, the plurality of groups of first through holes 102 are arranged along the axial direction of the roller 103, each group of first through holes 102 comprises a plurality of first through holes 102, the plurality of first through holes 102 of each group are arranged along the circumferential direction of the roller 103, one depth detection probe 104 is arranged in each first through hole 102, the plurality of depth detection probes 104 are uniformly distributed on the roller 103, each depth detection probe 104 can be abutted to a road surface, and the depth detection probes 104 are used for detecting the depth information of the road surface abutted by the depth detection probes; the processor is electrically connected to each depth detection probe 104, and the processor can determine whether there is a pavement crack 1 on the pavement and a real-time width value and a real-time depth value of the pavement crack 1 when the pavement crack 1 exists according to the depth information of the pavement detected by the plurality of depth detection probes 104 which are simultaneously contacted with the pavement.
The working principle of the embodiments is briefly described:
when the device is used, the vehicle body 101 is driven to travel on a road surface, the roller rolls on the road surface along with the travel of the vehicle body 101, the plurality of depth detection probes 104 on the roller 103 roll on the road surface in sequence, and the depth detection probes 104 detect the depth of the road surface at the contact position of the depth detection probes. Taking the pavement plane as a zero reference point, and when the pavement does not have pavement cracks 1, the depth information of the pavement detected by the depth detection probe 104 is always zero; when the pavement crack 1 appears on the pavement, the depth of the pavement at the pavement crack 1 is deeper than that of the pavement at the flat position, the width of the depth detection probes 104 with the detection results of zero, which are continuously distributed along the axial direction of the roller 103, is the real-time width of the pavement crack 1, and the depth value of the pavement at the detection positions of the depth detection probes 104 extending into the pavement crack 1 is the real-time depth of the pavement crack 1. The processor derives a real-time width value and a real-time depth value of the road surface crack 1 on the road surface based on the depths of the road surface detected by the plurality of depth detection probes 104. The device has higher intelligent degree and automation degree, and the intelligent repair operation of the pavement crack 1 is realized. In addition, since the device is directly inserted into the pavement crack 1 by the depth detection probe until the device is abutted against the bottom of the pavement crack 1, when the pavement crack 1 is covered with leaves and paper by wind, the leaves and paper can be extruded and deformed to be attached to the bottom of the pavement crack 1 under the extrusion of the depth detection probe 104. Therefore, the depth detection probe is used as a depth detection sensor and is analyzed by the processor to detect the depth and width information of the pavement crack, and compared with the traditional method for detecting the width and depth information of the pavement crack by using the visual detection system, the device can greatly reduce the influence of leaves and paper on the detection of the width and depth information of the pavement crack 1.
The intelligent road breakage inspection device disclosed by the invention can be used for simultaneously detecting a plurality of road surface cracks 1 on a road surface along the width direction of the road surface, detecting the depth and width information of each road surface crack 1, avoiding the influence caused by the road surface environment, preventing the interference of soft sundries such as leaves, paper and the like covered above the road surface cracks 1 on the detected width and depth of the road surface cracks 1, automatically performing intelligent analysis on the detected width and depth information of the road surface cracks 1 so as to generate more accurate road surface condition information, and enabling the intelligent road breakage inspection information acquisition to be more accurate.
Example 2:
on the basis of the embodiment 1, in order to draw a three-dimensional shape chart of the pavement crack 1, the pavement maintainer can more intuitively know the pavement condition information.
As shown in fig. 3 and 4, the vehicle body 101 is provided with a rotation angle detection mechanism 2, the rotation angle detection mechanism 2 is electrically connected with the processor, the rotation angle detection mechanism 2 is used for detecting the rotation angle of the roller 103, the data processor is used for calculating the real-time distance traveled by the vehicle body 101 according to the real-time rotation angle of the roller 103 and the diameter of the roller 103, and the processor is further electrically connected with a graph drawing module which is used for drawing a three-dimensional shape graph of the pavement crack 1 according to the real-time distance traveled by the vehicle body 101 and the real-time width value of the pavement crack 1.
When the vehicle body 101 moves along the length direction of the pavement crack 1 of the pavement, the rotating angle detection mechanism 2 is used for detecting the rotating angle of the roller 103 in real time, the rotating angle detection mechanism 2 transmits the rotating angle information of the roller 103 to the data processor, the data processor calculates the real-time distance of the vehicle body 101 moving along the length direction of the pavement crack 1 according to the rotating real-time angle of the roller 103 and the diameter of the roller 103, and the graph drawing module draws a three-dimensional shape graph of the pavement crack 1 according to the real-time distance of the vehicle body 101 moving along the length direction of the pavement crack 1 and the real-time width value and the real-time depth value of the pavement crack 1. Through setting up rotation angle detection mechanism 2 and figure drawing module, can draw the three-dimensional shape of road surface crack 1 according to the real-time distance that automobile body 101 marched in road surface crack 1 length direction and real-time width value and the real-time degree of depth value of road surface crack 1 to more audio-visual let highway maintainer know the situation information on road surface.
Example 3:
in addition to example 2, in order to know whether or not there is a micro crack in the road surface, more detailed information on the road surface condition can be provided to the road maintainer.
As shown in fig. 2, 4 and 5, the device further comprises an ultrasonic detection module, the ultrasonic detection module comprises an ultrasonic emitter 301 and an ultrasonic receiver 302, the ultrasonic emitter 301 and the ultrasonic receiver 302 are arranged on the depth detection probes 104 in two adjacent groups of first through holes 102 at intervals, the ultrasonic emitter 301 and the ultrasonic receiver 302 can be abutted against a road surface, ultrasonic waves emitted by the ultrasonic emitter 301 can be transmitted to the ultrasonic receiver 302 through the road surface and received by the ultrasonic receiver 302, the ultrasonic receiver 302 is electrically connected with a road surface crack analysis module, and the road surface crack analysis module is used for comparing ultrasonic signals transmitted by the road surface and received by the ultrasonic receiver 302 with ultrasonic source signals emitted by the ultrasonic emitter 301 and analyzing whether the road surface between the ultrasonic emitter 301 and the ultrasonic receiver 302 has a road surface crack 1 according to comparison results.
As the roller 103 rotates, when the ultrasonic transmitter 301 and the ultrasonic receiver 302 on the depth detection probes 104 in the two first through holes 102 axially adjacent along the roller 103 are abutted against the road surface, the ultrasonic waves transmitted by the ultrasonic transmitter 301 can be transmitted to the ultrasonic receiver 302 via the road surface and received by the ultrasonic receiver 302. Since the frequency and peak value of the ultrasonic wave emitted from the ultrasonic transmitter 301 are fixed, when there is a micro crack in the road surface between the ultrasonic transmitter 301 and the ultrasonic receiver 302, the frequency and peak value of the ultrasonic wave received by the ultrasonic receiver 302 are greatly different from the frequency of the ultrasonic wave received by the ultrasonic receiver 302 when there is no micro crack in the road surface between the two, and thus the road surface crack analysis module can analyze whether there is a micro crack in the road surface from the difference of the two received waves, thereby providing more detailed information on the road surface condition to the road maintainer.
As a preferred solution, as shown in fig. 3-5, each ultrasonic emitter 301 is provided with a trigger 9, each trigger 9 can be abutted against the ground, and when the trigger 9 on the ultrasonic emitter 301 is abutted against the ground, the trigger 9 triggers, so as to control the ultrasonic emitter 301 to emit ultrasonic waves. By arranging the trigger 9 on the ultrasonic transmitter 301, only the ultrasonic transmitter 301 which rotates along with the roller 103 to the ultrasonic transmitter 301 which is contacted with the ground is triggered by the ground, the ultrasonic transmitter 301 can transmit ultrasonic waves, and the rest ultrasonic transmitters 301 are in a silent state, so that the ultrasonic transmitters 301 which are not contacted with the ground can be prevented from transmitting ultrasonic waves, and the clutters are prevented from being received by the ultrasonic receiver 302 adjacent to the ultrasonic transmitter 301 which is contacted with the ground, so that whether the micro cracks exist on the analysis ground or not is interfered, and the accuracy of the analysis result of the pavement crack analysis module is ensured.
As a preferred solution, as shown in fig. 2, 4 and 5, the depth detection probe 104 includes a needle sleeve 401, a needle bar 402, a first spring 403 and a pressure sensor 404, the needle sleeve 401 is disposed in the first through hole 102, the needle bar 402 is slidably connected in the needle sleeve 401, the pressure sensor 404 is disposed in the needle sleeve 401, the first spring 403 is disposed between the needle bar 402 and the pressure sensor 404, the needle bar 402 can be abutted against a road surface, the pressure sensor 404 is electrically connected with the controller, the pressure sensor 404 is used for detecting a real-time pressing force applied by the needle bar 402 to the first spring 403 and transmitting the real-time pressing force to the controller, and the processor obtains a width value and a depth value of the road surface crack 1 on the road surface according to the real-time pressing forces detected by the pressure sensors 404 of the depth detection probes 104.
